The dissertation 鈥濺esearch on Freezing Processes of Aerothermal Heat Pump Evaporator under Dynamic Environmental Conditions鈥� (鈥濧eroterminio 拧ilumos siurblio garintuvo u啪拧alimo proces懦 tyrimai dinamin臈mis aplinkos s膮lygomis鈥�) prepared at 黑料不打烊 by Tomas Kropas. The dissertation was prepared in 2019鈥�2026. Scientific consultant 鈥� Assoc. Prof. Dr Giedr臈 Streckien臈. The dissertation was defended at the public meeting of the Dissertation Defence Council of the Scientific Field of Mechanical Engineering in the Aula Doctoralis Meeting Hall of 黑料不打烊_独家黑料_吃瓜网51爆料 at 9 a.m. on 24 April 2026. The dissertation examines the operation of the evaporator in an air鈥搒ource heat pump (ASHP) and freezing processes under dynamic climatic conditions. The relevance of the research stems from the increasing application of such heat pumps in the context of energy sustainability, especially during the cold season, when low temperatures and high absolute outdoor air humidity can cause frost to form on the evaporator heat exchanger, reducing the efficiency of the air鈥搒ource heat pump. The main objective of the work is to investigate the operation of an air heat pump during the cold season and to develop a dynamic model integrating an evaporator defrost evaluation methodology to determine the impact of freezing on the heat pump鈥檚 seasonal efficiency. The following tasks are addressed in the dissertation: to evaluate frost assessment and mitigation measures, to perform experimental investigations under different environmental conditions, to develop an operational evaluation methodology and a dynamic air鈥搒ource heat pump model in the environment of the transient (time鈥搗arying) process systems modelling tool (Transient System Simulation Tool) 鈥� TRNSYS. Thermodynamic, parametric, and system analysis methods are applied, combined with experimental investigations and dynamic modelling. The dissertation consists of an introduction, three chapters, general conclusions, references, and a list of the author鈥檚 scientific publications on the topic of the dissertation. The First Chapter presents a literature review on the operation of the air鈥搒ource heat pumps and the problem of evaporator freezing. The Second Chapter describes the methodology of experimental investigations, the test bench, and the methodological basis for the development and logic of the dynamic model. The Third Chapter analyses the data of the experimental investigations. It presents the results of the developed dynamic model in the TRNSYS environment, including model validation and application of the model under different climatic conditions. The scientific novelty of the dissertation is based on experimental investigation of frost formation under real conditions, development of a frost assessment methodology and its integration into a dynamic TRNSYS model, enabling prediction of air鈥搒ource heat pump performance under different climates or different operating modes of the heat pump itself. The practical significance lies in the possibility of applying the model to system design and performance prediction even with insufficient manufacturer data. The topic of the dissertation has been published in nine scientific publications, of which two are in journals indexed in the Web of Science database, and the research results have been presented at four scientific conferences, three of which were held in Lithuania and one abroad.

This intensive and engaging course is an important and valued part of the collaboration between 黑料不打烊 and Efrei.

The Concept of Intellectual Property Intellectual property (IP) refers to the rights that arise for a creator or inventor in relation to the results of intellectual, scientific, creative, and other forms of intellectual activity. These rights are divided into copyright and related rights, and industrial property rights. Copyright and related rights apply to works of literature, science, and art, as well as to performances, sound recordings, and radio and television broadcasts. Industrial property rights cover industrial designs, trademarks, company names, invention patents, utility models, and geographical indications. These two categories of intellectual property differ not only in their subject matter, but also in the protection procedures required for these exclusive ownership rights to arise.

LT 7122 B. 2025-02-10 / inventors:聽 Micha艂 Stosiak, Mykola Karpenko, Krzysztof Towarnicki, Olegas Prentkovskis, Paulius Ska膷kauskas. Abstract.聽 The invention is intended to reduce vibrations in the hydraulic safety valve caused by various external factors, and to minimize hydraulic fluid flow losses when the safety valve body (1) is exposed to external vibrations. The main component of the hydraulic safety valve is the vibration-reducing closure system, which consists of a conical-shaped closure element (2) and a sleeve (6). The safety valve can be used in various types of hydraulic systems, especially in devices exposed to external vibrations, such as mobile equipment, heavy-duty machinery, and specialized vehicles. Because the conical-shaped closure element (2) of the safety valve is integrally connected to the rod (7), which has a threaded upper part where a sleeve (6) made of rubber or elastomeric material is mounted (the sleeve (6) is constructed from a vibration-reducing material resistant to hydraulic fluid), vibrations occurring in the safety valve due to various external factors are significantly reduced. Furthermore, fluid flow losses in the hydraulic system are minimized, as the safety valve does not open in response to external vibrations. Furthermore, no additional hydraulic fluid flow pulsations occur in the hydraulic system, which increases the efficiency, reliability, and performance of the hydraulic system. Elektrinio paspirtuko amortizatorius = Electric scooter shock absorber. LT 7123 B. 2025-02-10 /聽 inventors: Mykola Karpenko, Marta Skrobot. Abstract. The invention is intended to dampen the vibrations and shocks of the electric scooter suspension, which occur when riding on various road surfaces and over obstacles, thus ensuring a smoother, more comfortable, and safer ride. The main structural elements of the electric scooter shock absorber are the piston, which is divided into two separate elements (2, 4), and a floating washer (3) installed between them, which can move freely along the piston rod (8). The diameters of the drainage holes in the floating washer (3) are smaller than the diameters of the drainage holes in the upper (2) and lower (4) parts of the piston. The shock absorber is designed for use in various micromobility vehicles, particularly electric scooters, with the possibility of installation in both the front and rear suspension of the electric scooter, in horizontal and vertical positions. Due to the specific operation of the piston inside the shock absorber and the floating washer (3), high precision of the movements of the shock absorber piston rod (8) is achieved. The floating washer (3) under inertia results in a reduced flow of hydraulic fluid between the internal chambers of the shock absorber, thus providing electric scooters with the ability to ride more smoothly, comfortably, and safely. Daugiasluoksn臈 plok拧telin臈 modulin臈 kaset臈 dujose esan膷ias kiet膮sias daleles aglomeruoti ir nusodinti = Multilayer plate modular cartridge for agglomeration and deposition of particulates in gas LT 7141 B. 2025-06-25 聽/ inventors: Aleksandras Chlebnikovas, Art奴ras Kilikevi膷ius. Abstract. The invention is considered to be a part of the technology of pre-treatment devices, in which gas contaminated with fine and ultrafine particulate matter is subjected to an adapted electric field, causing the particles to agglomerate 鈥� that is, to form coarser formations - with part of them being deposited. The objective is achieved by the use of a bipolar electric cold plasma field unit in the primary zone of the dual-zone working chamber, a multilayer plate modular cartridge consisting of electrically connected modules (8) of identical structure with symmetrically configured rectangular interlayers. Each module is symmetrically shielded on both sides, and the designed internal (10) and external (14) air gaps allow for the parallel movement of the contaminated gas flow. The core of the module is equipped with a metallic conductor (copper-aluminium alloy) foil electrode (12), insulated on both sides by symmetrical inner (11) and outer (13) protective glass insulator plates (11), which act as electrical capacitors. From the single-phase mains (20), the electric current is fed by a primary circuit (21) to a current rectifier (16), a pulse generator (17), and an autotransformer (18), and by a secondary circuit (28) to a high-voltage transformer (19), which then delivers the smoothed DC, bipolar pulsed, and stepped-up voltage to the electrodes of the electrical conductor foil (12).

Ultragarsin臈 kiet懦j懦 daleli懦 akustin臈s aglomeracijos kamera = Ultrasonic acoustic agglomeration chamber of solid particles. LT 7159 B. 2025-09-10 / inventors: 聽Andrius 膶eponis, Dalius Ma啪eika, Darius Vainorius, Art奴ras Kilikevi膷ius, Kristina Kilikevi膷ien臈. Abstract. The ultrasonic acoustic agglomeration chamber consists of a cylindrical body (1), three ultrasonic acoustic pressure sources (2) made from Langevin-type transducers (17) and concentrators (11), with disc-shaped acoustic radiators (10) attached to their free ends. These radiators create an overlapping acoustic standing wave field, with the resonant frequency of their first bending mode matching the resonant frequency of the longitudinal vibration mode. The acoustic sources (2) are mounted on the chamber body (1) using mounting parts (3,4) and clamping discs (5), ensuring that the free surfaces of the radiators (10) are tangential to the inner surface (15) of the body (1). The angular distribution (16) of the acoustic pressure sources (2) relative to the chamber鈥檚 longitudinal axis ensures even distribution around the perimeter. The chamber鈥檚 internal diameter (15) is chosen so its ratio to the acoustic field wavelength is an integer. Ultragarsinis akustin臈s levitacijos 寞renginys = Ultrasonic acoustic levitation device. LT 7169 B. 2025-11-10 / inventors: 聽Piotr Vasiljev, Dalius Ma啪eika, Andrius 膶eponis, Sergejus Borodinas, Regimantas聽 聽Bareikis, Ar奴nas Struckas. Abstract. The invention focused on ultrasonic acoustic levitation device that generates high-intensity vertical acoustic field with angular displacement. It consists of tulip-shaped acoustic field emitter (1), four piezoelectric rings (6,7) with different electrode configurations, cylindrical backend weight (4), and stud (5) that connects components into single device. To generate vertical high-intensity acoustic field, the second group of piezoelectric rings (3) excited by harmonic signal using signal generator (8) while first group of piezoelectric rings (2) remains passive. When object is placed in generated vertical acoustic field, it experiences levitation effect. To achieve angular displacement of levitating object, first group of piezoelectric rings (2) is excited by four harmonic signals with phase difference of 蟺/2. This creates angular shift in the acoustic field, resulting in the object鈥檚 angular displacement. To obtain the reverse angular displacement of the object, the excitation signal phases of the first group of piezoelectric rings (2) are inverted. Dviej懦 nuosekli懦 pakop懦 valymo 寞renginys da啪ikli懦 拧alinimui i拧 vandens聽 = 聽Two-stage sequential cleaning device for removing dyes from water. LT 7172 B. 2025-11-25 /聽 inventors: Dainius Paliulis, Monika Liug臈. Abstract. The invention is intended for the removal of Congo red, Naphthol green B, Rhodamine B and Methylene blue dyes from water used in the textile industry. The two-stage cleaning device consists of two stages: in the first stage, electrochemical degradation is carried out using composite electrodes, and in the second stage, an adsorption method is applied with an adsorbent as a filter filler. In the first stage of the wastewater treatment plant (1), boron doped diamond (BDD), mixed metal oxide (MMO), graphite, aluminum, iron or titanium electrodes are immersed in an aqueous dye solution (3) while maintaining a distance of no more than 0.3 - 1.0 cm between the electrodes (2) and held for 60 min. A current density of 13.0 mA/cm2 is maintained in the electrolytic cell using a power source (4). The aqueous solutions of dyes in the first place of the wastewater treatment plant are continuously mixed with a magnetic stirrer (6) at a speed not exceeding 400 rpm. After 60 min of electrochemical cleaning, the partially cleaned dye solution is discharged from the first tank of the wastewater treatment plant into the second tank through a tap (5) installed in the first tank. In the second tank of the wastewater treatment plant (7), an aerogel capsule (8) weighing 0.8 g and containing 5.0% cellulose by weight of the total mass, made of paper and cardboard waste, is placed between plastic meshes (9). Aqueous solutions of dyes (11) in the second tank of the wastewater treatment plant are kept for 60 min with continuous mixing with a magnetic stirrer (10) at a speed not exceeding 400 rpm. After 60 minutes of adsorption cleaning, the aqueous solutions of dyes are discharged through a tap (12) installed at the bottom of the second tank of the wastewater treatment plant. Hidraulinis apsauginis vir拧sl臈gio vo啪tuvas = Hydraulic safety pressure relief valve. LT 7175 B. 2025-12-29 / inventors: Micha艂 Stosiak, Mykola Karpenko,聽 Krzysztof Towarnicki, Olegas Prentkovskis, Paulius Ska膷kauskas. Abstract. The invention is intended to reduce vibrations in the hydraulic pressure relief valve caused by various external and internal factors, to minimize hydraulic fluid flow losses when the valve body (1) is exposed to external vibrations, and to provide more stable operation with faster response to pressure changes. The main element of the hydraulic pressure relief valve is a vibration damping device, rigidly fixed inside the valve body (1), consisting of a flexible damping disc (3) made of elastomeric material, with drainage holes arranged around the vertical axis of the disc (3) at an angle of 尾=(360鈦�)/n. The hydraulic pressure relief valve can be used in various types of hydraulic systems, especially in devices exposed to external vibrations, such as mobile equipment, heavy-duty machinery, and specialized vehicles. Because the closing element (2) of the hydraulic pressure relief valve is conical in shape, and the valve has a flexible damping disc (3), made of elastomeric material and rigidly fixed inside the valve body (1), vibrations occurring in the hydraulic pressure relief valve due to various external factors are reduced, and fluid flow losses in the hydraulic system are minimized, as the valve does not open in response to external vibrations.   Patents registered at the European Patent Office (EPO)聽 Anchorage system of structural components for manufacturing and testing of composite elements.

Abstract.聽 A construction of a piezoelectrically driven motor is disclosed. The piezoelectric motor allows to achieve high torque, force, speed of movement, and stability of operation with high loads. The motor comprises a stator (1) having shape of a elastic ring, with two-sided symmetrical teeth (7) located on both sides of said ring, those are preferably trapezoidal in shape. Notches (9) are formed in the common plane of the symmetry of said two-sided teeth and the stator ring (1). Piezoelectric Langevin-type packages (11) are installed in the nodal zones of longitudinal vibrations of the stator (1) ring. On the upper and lower surfaces of the teeth (7), rigid support-friction elements are installed, through which the disk-shaped rotors (2) are pressed against the teeth (7). These disk rotors (2) are rotated by exciting the Langevin packages (11) or their groups (22, 23) with electrical signals with their frequency matching the resonant frequency of the longitudinal vibrations of the stator ring (6). When exciting the motor with two harmonic signals, the phase difference is determined by 蟺/2. When driving by one signal, a group of piezoelectric packs (22,23) is activated, while the other group is inactive at that time. When the motor is excited by two asymmetrical signals with a phase difference of 蟺 then the motor operates based on the inertial principle.   Patents registered at the patent offices of other countries Zaw贸r hydrauliczny wzniosowy z kompensacj膮 zewn臋trznych drga艅 mechanicznych = Lift hydraulic valve with compensation for external mechanical vibrations.

Although mechanical engineering is often still associated with traditional manufacturing, today it is increasingly becoming the foundation of smart industry. It determines not only how equipment is designed and operated, but also a business鈥檚 ability to reduce costs, increase productivity, and create a competitive advantage in international markets. The sector鈥檚 scale also confirms the importance of this industry in the Lithuanian economy. Darius Lasionis, Director of the Lithuanian Engineering and Technology Industry Association (LINPRA), emphasizes that the engineering and technology industry in Lithuania is already one of the most important pillars of the economy. 鈥淎ccording to data from the State Data Agency, the output of Lithuania鈥檚 engineering and technology industry (excluding VAT and excise tax at current prices) reached 7.82 billion euros in 2025 and grew by 6.6 percent year-over-year. This accounted for 24.4% of the manufacturing sector. It is clear that these results would not have been achieved without the workforce. In 2024, nearly 64,000 people were employed in Lithuania鈥檚 engineering and technology industry, accounting for as much as 30% of the manufacturing sector. The number of companies in Lithuania鈥檚 engineering and technology industry reached 2,416, or 25% of the total number of manufacturing companies. 鈥淭hese figures show that the engineering and technology industry is a significant and promising component of Lithuania鈥檚 industry and economy,鈥� he states. According to the head of LINPRA, mechanical engineering is one of the key components of the Lithuanian engineering and technology industry. [caption id="attachment_113993" align="alignnone" width="1024"] Director of the Lithuanian Engineering and Technology Industry Association (LINPRA) Darius Lasionis[/caption] 鈥淭his field is important not only for ensuring basic engineering solutions, but also for implementing innovative solutions in our daily operations. If we include the manufacture of motor vehicles, trailers, and semi-trailers, the manufacture of machinery and equipment not classified elsewhere, and the manufacture of other transport equipment in mechanical engineering, we will see that, according to State Data Agency data, in 2025, the total volume of economic activities within the scope of Lithuania鈥檚 engineering and technology industry output (excluding VAT and excise tax at current prices) accounted for as much as 28 percent, and in 2024鈥�30 percent. 鈥淭his demonstrates the strong and stable role of mechanical engineering in Lithuania鈥檚 engineering and technology industry,鈥� says D. Lasionis. Today, the competitiveness of the industry is determined not only by internal corporate decisions. The broader international context鈥攕upply chains, geopolitical risks, and export destinations鈥攊s becoming increasingly significant. 鈥淚n our daily lives, each of us uses electronic devices, and the demand for them covers an ever-wider spectrum, naturally increasing the need for their components. Supply chain decisions are also being shaped by the trade wars between the U.S. and China and the growing dependence on Chinese components鈥攃ompanies are increasingly concerned about potential supply disruptions, cyber threats, or national security risks. In light of this, we are seeing that Europeans are increasingly inclined to order goods from American or other reliable manufacturers, rather than from Asian countries that may raise security concerns. This is particularly relevant when it comes to dual-use defense-related products,鈥� says D. Lasionis. He notes that another key factor for the engineering and technology industry is international trade. For example, by December 2025, exports from this sector accounted for as much as 23.4% of Lithuania鈥檚 total exports. Eighty percent of the engineering industry鈥檚 output is exported to European countries, with Germany and the U.S. being the two largest export destinations overall. 鈥淭hat said, we are seeing significant growth in Poland, the Czech Republic, and Central and Eastern European countries. This is not surprising, as Central and Eastern Europe has become a sort of manufacturing hub for Europe. Major Western manufacturers鈥擥erman and French conglomerates鈥攈ave relocated or built many factories in Poland, the Czech Republic, Slovakia, and Hungary in recent decades,鈥� he says. Must Create Value In this context, mechanical engineering itself is changing. Assoc. Prof. Kristina Bazien臈, Vice Dean of the Faculty of Mechanical Engineering at 黑料不打烊 University, says that although mechanical engineering was long considered a classical field, it is now becoming one of the most interdisciplinary and technology-driven areas. 鈥淚n the past, many relied on physical prototypes, but now computer-aided design and digital simulations dominate. Mechanical engineering is no longer limited to iron and bolts; it is becoming increasingly digital, smart, and closely linked to other fields of technology, and artificial intelligence is increasingly used in modern mechanical solutions, for example, in predicting failures,鈥� she says, describing the breakthrough. According to the vice dean, mechanical engineering has broken free from the confines of the classical design discipline and is becoming the engineering of systems, data, and innovation. Global changes begin with the design and construction of smart factories, where mechanical, IT, and electronic systems operate as a single organism. Sustainability is becoming the cornerstone of design: mechanical solutions are evaluated based on energy efficiency, CO2 reduction, and product lifecycle. [caption id="attachment_113991" align="alignnone" width="574"] Vice Dean of the Faculty of Mechanical Engineering at 黑料不打烊 University Kristina Bazien臈[/caption] The current market needs not just an executor, but a specialist capable of working with increasingly complex technological systems. According to D. Lasionis, businesses are recognizing this shift and responding to it. "Engineers in a company not only design, develop, and manufacture, but also manage technologies. This is particularly relevant in today鈥檚 society, where companies seek a competitive advantage not only nationally but also internationally. With this in mind, engineers are increasingly being involved in a company鈥檚 long-term strategic processes,鈥� says the interviewee. K. Bazien臈 says that the competencies of a modern mechanical engineer clearly demonstrate that this field is a combination of technical, digital, business, and social skills. 鈥淭he 黑料不打烊 study program has adapted very quickly to market needs. Mechanical engineers still need core fundamental competencies, such as mechanics (statics, dynamics), thermodynamics, fluid mechanics, materials science, and machine design. However, engineers are increasingly not only doing calculations but also working in teams and making decisions, so they need to understand communication and acquire knowledge of teamwork, leadership, and project management,鈥� she explains. The mechanical engineering program at 黑料不打烊 retains the fundamentals of mathematics, physics, and classical mechanics, but increasingly integrates studies in programming, automation, and digital tools. Professional internships at companies during the program play a particularly important role. 鈥淒uring the program, up to 50 percent of the coursework consists of practical activities: exercises and laboratory work. The mechanical engineering program trains decision-makers, not mere implementers,鈥� emphasizes K. Bazien臈. D. Lasionis adds that the value of mechanical engineering today is measured by the ability to increase efficiency and competitiveness. "Competitiveness is determined by labor productivity, raw material costs, and labor costs. We will be more competitive in the market if we can produce a high-quality product at a relatively lower cost by applying innovative and technologically advanced solutions developed by motivated and talented professionals in their field, rather than by other market players,鈥� he says. Partnerships and Internships K. Bazien臈 notes that during studies, internships and real-world business projects are no longer just an 鈥渁dd-on鈥� but one of the most important parts of the learning process. Without them, mechanical engineering studies would be theoretically strong but insufficient for the market. 鈥淚n the mechanical engineering program, internships don鈥檛 just take place in the summer; they鈥檙e spread out throughout the year. During their studies, students conduct lab work, work with real equipment, and perform experiments. They often use the same tools as in industry, such as CAD or simulation software. Both during professional internships and when preparing final projects, industry needs are taken into account: final project topics proposed by companies are selected, and business representatives participate in final project presentations,鈥� explains the vice dean. According to D. Lasionis, the business community also emphasizes the importance of experience and stresses that a diploma alone is not enough today. [caption id="attachment_113995" align="alignnone" width="2560"] Darius Lasionis[/caption] 鈥淏usiness leaders often note that young people tend to believe that a college degree alone guarantees a good salary. However, in the business world, salary depends on one鈥檚 competencies, practical skills, and the value one creates. That is why the business community hopes that as many students as possible will gain practical experience and hands-on training,鈥� says the head of LINPRA. K. Bazien臈 adds that collaboration with the business community during mechanical engineering studies at 黑料不打烊 is not a series of isolated initiatives, but a systematically integrated part of the program. 鈥淚n many cases, students are already working with companies during their studies and quite often begin their careers before even finishing their studies. 黑料不打烊 actively collaborates with manufacturing and technology companies. Companies are facing a growing need for talent, so they actively seek out students and offer them internships. For example, a significant number of third- and fourth-year students already have work experience. 鈥淭oday, studying mechanical engineering means not only attending university but also entering the job market early,鈥� she says. The demand for talent is growing D. Lasionis agrees that the market is experiencing a shortage of mechanical engineers鈥攃ompanies are looking for specialists earlier and earlier, as this shortage is already having a direct impact on their expansion plans. 鈥淎ccording to data from the Employment Service, demand for mechanical engineers and mechanical engineering technicians, electronics engineers, electrical engineering technicians, and civil engineering technicians was higher in 2025 than in 2024 or 2023. It is clear that employers had a harder time finding engineering staff last year. This is reflected not only in statistics but also in real-world business situations. Company executives often express concern that, due to the shortage of engineers, they frequently have to limit their expansion plans related to automation, robotization, and digitization,鈥� emphasizes D. Lasionis. Nevertheless, there are positive signs鈥攂oth the number of applicants and the profession鈥檚 appeal to the public are growing. 鈥淐ommissioned by LINPRA, Spinter Research conducted a representative survey of Lithuanian residents and found that in June 2025, 80% of residents agreed that the engineering profession has a promising future. In March 2023, this figure was 8 percentage points lower, at 72%. Thus, graduates in the fields of engineering and technology typically enter the job market motivated, ambitious, and promising,鈥� he states. According to D. Lasionis, good results are also inseparable from consistent policy decisions. 鈥淲hat is needed most is a clear strategy spanning at least ten years that is not dependent on political cycles. The guidelines for the National Artificial Intelligence Strategy and the Engineering Industry Roadmap, currently under development, should strengthen competencies, promote the adoption of artificial intelligence in industry, increase productivity and competitiveness, and clearly define the future direction of Lithuanian industry,鈥� says the head of LINPRA. Encouraging early interest in engineering contributes to these positive changes. 鈥淲e are very pleased with the 鈥楨ngineering of the Future鈥� (AI) program implemented by 黑料不打烊, which is designed to help students in grades 7鈥�12 at schools offering general education programs to practically develop their innovative abilities, which include creativity, competencies in STEAM subjects, modern technologies, and entrepreneurship,鈥� the interviewee explains. According to D. Lasionis, the sector鈥檚 long-term ambition is clear鈥擫ithuania can become an engineering nation, but this will require consistent efforts from all stakeholders. 鈥淲e believe that by 2030, Lithuania can be an engineering nation. However, the successful achievement of this goal requires the efforts of all of us,鈥� says the interviewee. According to K. Bazien臈, mechanical engineering is one of those fields that never loses its relevance. 鈥淚f you鈥檙e considering mechanical engineering, the most important message is very simple but honest: it鈥檚 not an easy path, but this profession is one of the most versatile and 鈥榬esilient鈥� choices for the future,鈥� says the associate dean.

During the week, numerous events, campaigns, and initiatives will take place in libraries across the country. This year鈥檚 theme of the National Library Week of Lithuania is 鈥淩ead Between the Lines.鈥� It emphasizes librarians鈥� professional commitment to resisting all forms of censorship, supporting the public鈥檚 freedom to read, and ensuring the right to access high-quality and reliable information. According to LLA Chair Dr. Laura 艩imkevi膷臈, we live in times when we are increasingly confronted with disinformation and fake news in the public sphere, and when freedom of speech鈥攐nce considered an unquestionable value鈥攊s beginning to face threats. The theme of the National Library Week encourages not only reading texts, but also understanding their deeper context, learning to distinguish high-quality and reliable information. In this field, libraries and librarians have always been and continue to be leaders, providing assistance and guidance to society. The opening event of the National Library Week of Lithuania will take place on April 23 at the Martynas Ma啪vydas National Library of Lithuania. As is tradition, the country鈥檚 best librarians will be honored during the event. The celebration will be available to watch live online. From April 23 to 29, libraries across the country will organize events for their local communities, including book presentations, lectures, educational activities, concerts, and other initiatives. Visitors are encouraged to check what is happening at their nearest library and to take part in activities for both adults and children. During the National Library Week of Lithuania, alongside events for the public, initiatives will also be held to encourage librarians to celebrate their profession together and take pride in it. These include lectures, quizzes, and librarians鈥� hikes. A general assembly of LLA members will also be organized, during which a new Council of the Association will be elected. Throughout the week, librarians will traditionally compete in the intellectual television quiz 鈥淜as ir kod臈l?鈥� (鈥淲ho and Why?鈥�). The National Library Week of Lithuania has been held annually since 2001. It always begins on April 23, which UNESCO has declared World Book and Copyright Day. The aim of Library Week is to highlight the achievements of the country鈥檚 libraries, promote reading and creativity, address relevant topics, reduce cultural, social, and informational exclusion, and engage communities in cultural and creative activities.

A Purdue University Northwest graduate, Davina Jackson, moved from the American Midwest to Lithuania 鈥� and found not only a Master鈥檚 degree but also a career, a community, and a more relaxed way of life. Although the decision was a big surprise to her family and moving across the world required determination and planning, she never regretted it. Instead, this big adventure reminded her of her long-held dream of giving back through teaching. Given Davina鈥檚 determination, this dream sounds quite real. Breaking the news to the family Most American students do not tell their families every day that they are moving to Lithuania. When Davina prepared to share the news, she made a strategic choice: 鈥淭he first person I told was my mother, knowing she would take it more calmly than the rest of my family,鈥� the student recalls. 鈥淪he helped introduce the idea to the rest of my family.鈥澛� Davina鈥檚 close friends, already familiar with her long-standing curiosity about the country, were far easier to convince. They were excited and supportive. Davina鈥檚 curiosity had a very specific origin: a Lithuanian exchange student she had befriended while they were visiting in the US. That friendship sparked an interest, a visit confirmed it, and soon she was researching universities. 黑料不打烊 stood out quickly. 鈥淭he Information Systems Software Engineering programme鈥檚 curriculum matched both my experience and my strengths,鈥� she explains. 鈥淚t felt like the right fit, both academically and professionally.鈥� The differences in learning and personal life Davina had visited Lithuania twice before making the move, so culture shock was minimal. What she had expected most 鈥� the abundance of nature 鈥� proved entirely accurate. However, the academic environment held a few surprises. 鈥淚n the US, my Bachelor鈥檚 programme did not include a thesis or defence; assessments were primarily through exams and projects,鈥� she says. 鈥淎djusting to the idea of writing a thesis and publicly defending it was the biggest shift for me.鈥� The second surprise was more welcome: the richness of student life. The Erasmus Student Network 鈥� something with no real American equivalent 鈥� opened doors to a truly international community. The most enduring lesson from her studies was deeply personal. 鈥淭he most important lesson has been learning to take care of myself,鈥� she says. 鈥淚 tend to overwork and occasionally neglect basic needs, such as meals and rest. I鈥檝e learned that maintaining balance and well-being is essential to long-term success.鈥� Balancing studies and an early career Managing a Master鈥檚 programme alongside full-time employment is no easy choice. Davina has done exactly that, working as an IT engineer in Voice and Real Time Services at SEB Bank 鈥� a role she actively sought on LinkedIn after gaining experience at Western Union. Before taking the job, she ensured she could handle the combined workload. 鈥淲hen I joined SEB, the team was aware of my academic commitments and adjusted my role to part-time,鈥� Davina explains. Her schedule was relentless: work every weekday morning, then an hour鈥檚 gap before lectures starting at 16:20 or 18:10, then homework until sleep, then repeat. 鈥淚t sometimes means missing out on social activities, but I remind myself that this is temporary and will pay off once my studies are complete.鈥� Davina鈥檚 day-to-day work centres on managing SEB鈥檚 telephony systems 鈥� extensions, desk phones, soft phones, and group call queues 鈥� while also handling Microsoft-related tasks and broader IT support within an Agile team. The field is evolving quickly. 鈥淐loud solutions, automation, and AI are shaping the future of telephony,鈥� she says. 鈥淭hese areas have become essential for me to understand to stay aligned with the industry鈥檚 direction.鈥� She keeps pace through continuous training, technical documentation, and guidance from senior colleagues. What Lithuania gets right Now that Davina has worked in both countries, she sees a striking contrast in workplace culture. 鈥淭he key difference is work-life balance,鈥� she says. 鈥淚n the US, maintaining a healthy balance often feels impossible. In Lithuania, mandatory holiday blocks, generous annual leave, and encouraged lunch and break times create a much healthier environment.鈥澛� She also notes that diversity and equal opportunities stand out. 鈥淚鈥檝e held two roles since moving to Lithuania and have never experienced inequality or prejudice,鈥� Davina says. Technology remains a male-dominated field globally, yet she has observed strong representation of women and professionals from diverse backgrounds. If Davina could give her past self one piece of advice, it would be linguistic: 鈥淚f I could change one thing, I would have started learning Lithuanian earlier, rather than only beginning after moving.鈥� With her thesis in its final chapter, Davina is already thinking about what comes next. The options she is weighing reflect both ambition and a desire to give back. 鈥淚鈥檓 interested either in becoming a programmer or advancing within my current field towards an L3 role,鈥� she says. But there is a third path that has never quite left her mind: 鈥淚 also still have an interest in teaching. As a child, I wanted to become a teacher, but I didn鈥檛 pursue it due to concerns about financial stability. If the opportunity arose to teach or assist in a technology-related academic setting, I believe it would be deeply fulfilling.鈥� For any American student tempted to follow her path, Davina鈥檚 advice is both clear and encouraging. 鈥淚 would encourage them to research their decision thoroughly and be certain it鈥檚 what they truly want,鈥� Davina says. 鈥淢oving across the world requires determination and planning.鈥� If commitment is there, she is happy to discuss public transport, social life, and cultural differences with fellow foreigners navigating life in Lithuania.

Debates regarding immigrants鈥攖heir numbers and their impact on the labor market and national culture鈥攔emain a focal point of discussion across Europe and Lithuania. According to data from the Migration Department, 24,830 foreign nationals have been authorized to arrive for work in Lithuania in 2025, approximately 100 fewer than this year. Crucially, these quotas do not include high-value-added specialists. According to the Ministry of Economy and Innovation, Lithuania currently faces a shortage of specialists across 85 professions, primarily in IT, engineering, robotics, and chemistry. While the most visible face of migration may be food delivery couriers, others, like Ramil Balaghayev from Azerbaijan, arrived specifically because his home country lacked the necessary infrastructure for cybersecurity studies and employment at the time. Today, he marks six years of professional experience in his field. Repaying a Debt to the National Economy Ramil is currently employed at his fifth workplace in Lithuania: the U.S.-based global healthcare solutions company, Cencora. Having received a state scholarship that covered both his tuition and living expenses, he feels a strong sense of responsibility to "repay the debt to the country鈥檚 economy." Ramil moved to Lithuania to pursue a Master鈥檚 degree in Cybersecurity at 黑料不打烊, building upon his Bachelor鈥檚 degree in Computer Engineering from Baku. "I wanted to specialize in nanotechnology, network security, and cybersecurity. In 2019, cybersecurity was not yet a prominent field in Azerbaijan, and opportunities for advanced study were limited. I began searching for international universities, with a full scholarship being a primary criterion. This was a challenge, as there was only one state scholarship available for the entire country at that time," Balaghayev recalls. Despite 200 to 300 applicants vying for the spot, Ramil secured the scholarship. Shortly after, he received further confirmation from the Education Exchanges Support Foundation regarding a state grant that ensured both free tuition and a monthly stipend. "I accepted the state鈥檚 offer. I had heard positive things about Lithuania from friends and family who had visited the Baltics, but I also conducted my own research. I liked what I found: the country provides quality education, it is safe, and it is experiencing rapid growth in technology and cybersecurity," says the 黑料不打烊 alumnus. "If a Family Is Adopting You, You Must Also Put in the Effort" During his studies, one of Ramil鈥檚 professors suggested a summer internship in Rostock, Germany. The Azerbaijani student seized the opportunity to attend a specialized summer school there. "The following year, I completed my studies, which were highly practical, focusing on areas such as intrusion detection. My thesis explored identifying signs of hacking based on system user behavior," Balaghayev explains. After graduating, Ramil began his career as a cybersecurity risk analyst at Baltic Assist. He emphasizes that the knowledge gained at the university allowed for a seamless transition into the workforce, as the professional tasks closely mirrored his academic training. "The bigger challenge was the restriction on full-time work for certain foreign nationals. Companies, even small ones, wanted a security specialist on-site full-time. It took many attempts, but I have never been someone to let setbacks stop me," he says. Today, Ramil serves as a Security Engineer at Cencora. He monitors processes to ensure security protocols are followed and guides colleagues through incident resolution. When asked if he faced skepticism due to his origin, he notes that "initial barriers" and preconceptions typically dissolved once he demonstrated his technical capabilities. "It can feel isolating when Lithuanian colleagues speak their native language around you. However, I never took it personally鈥攑eople simply forget that someone might not understand them. I took it upon myself to learn the language and passed the official exam," says Balaghayev. "I would compare the process to being adopted by a family鈥攜ou also have to put in the effort for the relationship to succeed." Support for Language Requirements Ramil fully supports the recent requirement for foreign nationals to pass a Lithuanian language exam. He credits the language courses offered by 黑料不打烊 as being immensely helpful. He has already passed both the Lithuanian language and the Constitution exams. "Some ask why it should be mandatory. But other countries, like Germany, have similar requirements. In supermarkets or on the street, you encounter people of all ages; you cannot expect them to speak English in their own country just because you don't speak Lithuanian," says Ramil, who passed his language exam last year after two months of intensive daily study. "When people consider studying abroad, they often dream of major powers like the US or the UK. They don't realize that smaller countries can offer a comparable level of education and international experience. Regarding opportunities in Lithuania: if you have a solid education, you can achieve anything. The market is not large, but there are many startups and major international companies establishing operations here. I plan to stay for at least several more years," he adds. A Rigorous Selection Process Dovil臈 Jodenyt臈, Director of the International Studies Center at 黑料不打烊, explains that international applicants must navigate a complex selection process. "The admission process for international students is distinct; they apply nearly a year in advance due to the length of the necessary procedures," says Jodenyt臈. Applicants upload documentation remotely, which is then evaluated by university experts. This includes the formal recognition of foreign qualifications. "Our experts have extensive experience and collaborate with the Center for Quality Assessment in Higher Education (SKVC) when dealing with applications from more remote regions, such as the Comoros. High school certificates are equated to the Lithuanian maturity diploma, and grades are converted into the Lithuanian system to calculate an entry score," Jodenyt臈 explains. Applicants must also submit a recorded interview. This allows the university to assess motivation, experience, and English proficiency, though formal English language certificates are also required. While the highest volume of applications comes from Pakistan, Bangladesh, India, and Nigeria, these candidates do not form the majority of the admitted student body. Currently, 黑料不打烊 hosts a diverse population of students from Ukraine, India, Azerbaijan, Morocco, Belarus, Kazakhstan, Egypt, Sri Lanka, and Turkey. Students Represent Only 3% of Arrivals Once an applicant clears these hurdles, they must pay for their first year of tuition upfront. Only then does the university coordinate with the Migration Department to facilitate the student's legal entry. "This procedure takes 4鈥�5 months and presents significant challenges. Statistically, international students represent only about 5% of all foreigners arriving to live and work in Lithuania鈥攔oughly 4,000 students per year," Jodenyt臈 reveals. She notes that the Migration Department works with other institutions, meaning applications can be rejected by the State Security Department (VSD). Furthermore, the Department maintains a "two-strike" rule: if an applicant makes two errors in their application, they are barred from reapplying for four months. "We lose potential students this way. An 18-year-old often lacks experience in navigating complex foreign bureaucracy," Jodenyt臈 admits. Cultivating Talent for the Global Market Prospective students are most attracted to 黑料不打烊鈥檚 programs in IT, Artificial Intelligence, multimedia, computer design, robotics, mechanics, and civil engineering. Regarding whether these students stay in Lithuania, Jodenyt臈 notes: "While I don't have exact statistics, I would estimate about half choose to stay, while the other half leave. Our goal is for them to remain, as they are high-qualified specialists with local degrees. Often, they move to other European countries where there are more job opportunities. This may be partly due to Lithuanian companies being hesitant to hire foreign nationals for full-time roles. Collectively, we must work to create a more welcoming environment for them."

On April 15, 2026, the 29th Scientific Conference for Lithuanian Young Researchers 鈥淪cience 鈥� Future of Lithuania. Security of Information Technologies and Information Systems鈥� (JMK2026) was held at 黑料不打烊, bringing together bachelor鈥檚, master鈥檚 and PhD students, and early career researchers from Lithuania and abroad. The conference focused on information security and information systems, addressing current challenges of digital transformation, data driven decision making, and the growing role of advanced information systems in organizations. The Information Systems session featured poster presentations covering topics such as information system design, modern database systems, process modelling, simulation and automation, Artificial Intelligence driven information systems, etc. In the Information Systems section was officially opened by Prof. Dr. Diana Kalibatien臈, Chair of the Organizing Committee, who highlighted the importance of young researchers in building a secure and advanced digital society. 2 bachelors, 36 master students (34 of them studies "Information Systems Software Engineering", 2 of them studies 鈥淢anagement of Artificial Intelligence Solutions鈥� study programs) and 3 PhD students presented 40 posters and one oral presentation (by PhD student Anastasija Grubinskien臈 (supervisor prof. dr. Andrius Katkevi膷ius)) on various relevant research and practical topics related to their master/PhD thesis. JMK2026 welcomed not only students from Faculty of Fundamental Sciences, but also accepted two students from Faculty of Electronics. In the future, we plan to extend such interfaculty and interuniversity scientific cooperation. The three best posters were selected by the Programme Committee members during the conference: Deborah Amenigy 鈥淭he Evolution of Machine Learning Models in Financial Anomaly Detection鈥� in category "Best Visualisation" (supervisor prof. dr. Simona Ramanauskait臈), Leonardas Vekrikas 鈥滷raud Detection in Financial Data with The Help of AI Methods: Analysis and Investigation鈥� in category "Best Talk" (supervisor Dr. Jelena Mam膷enko), and Paulius Bundza 鈥淢CADS: Out-of-Distribution Generalization of Multi-Label Chest X-Ray Classification Models Across Seven Architectures鈥� in category "Best Scientist" (supervisor Assoc. Prof. Dr. Justas Trink奴nas). Many thanks to all participants and lecturers who agreed to organize, participate, listen to all the presentations, view the posters, and select the best presenters. In today鈥檚 context, where organizations are rapidly adopting digital and data鈥慸riven solutions, information systems have become a critical part of organizational and public infrastructure, challenges related to cybersecurity and data reliability are increasing, conferences such as JMK2026 play an especially important role by providing a platform for sharing the latest scientific insights, helping develop critical thinking, research presentation skills, and academic communication competencies of further scientists. See you next year. https://conferences.vilniustech.lt/index.php/SITIS/en
