The catalyst of such creativity in higher education is the acquisition of new knowledge and the living of new experiences. Then, within innovation and incubation environments, new thinking enriches knowledge handed down from previous generations, enlivens contemporary lives and informs future growth. Emergent knowledge encourages recognition of the limitations of traditional academic disciplines, exploration of new interdisciplinary frontiers, and, from this, novel transdisciplinary insights that unlock human potential and improve human conditions. In response, the University for Business and Technology intends to build collaboration environments to enable discovery and access, interpretation and analysis, creation and sharing of knowledge. These aspirations recognize the synergies possible when individual discovery is reinforced by collective inquiry with the shared purpose of using information ...

As a matter of fact, metal devices needed to connect the different elements often introduce a strong discontinuity in the current cross-section due to their size and to the presence of cavities needed to assemble the joint. Within the framework of a wider research project jointly carried out between Politecnico di Milano and DLC Consulting Srl on an innovative wall system, axial tests on a reference monolithic benchmark and three single joint specimens differing by reinforcement and/or mortar filling details have been carried out. A critical interpretation of the test results and of the compressive behaviour of the joints is provided by means of a numerical investigation through nonlinear static analyses performed with the software Abaqus.

The development and deployment of an effective, fast and robust sensing architecture able to detect, characterize and sort solid waste products is of primary importance. Near InfraRed (NIR) based HyperSpectral Imaging (HSI) techniques to detect materials to recycle and/or solid waste products to process represents an interesting solution to address quality control issues in these sectors. In this paper, are presented two different case studies on the utilization of NIR-HSI to detect contaminants in household plastic packaging waste and recognize materials occurring in processed monitors and flat screen waste. The proposed approach consists of a cascade detection based on Partial Least Squares – Discriminant Analysis (PLS-DA) classifiers applied on hyprspectral images acquired in NIR range (1000-1700 nm).

The most influential tool of the Russian Federation is the information warfare, composed with hybrid tactics, attempting to set a foot in the Western Balkans. Qualitative methods were used for analysis and the findings. The main results indicate that Russia has divers’ methods to impact political developments in the Balkans. Russia has been interested in this part of Europe, and it engages with all interested sides in the region. With its state propaganda, Russia at least has the ability to divert the policies of the Western Balkan states towards the EU. Moscow prefers the status of neutrality of the countries that emerged from the Yugoslav Federation. In other words, Kremlin challenges the U.S. on some levels and the sources of Russian influence primarily are stemming from information warfare strategies integrated in different platforms. Recently the EU and the U.S. have expressed thei...

Being the weakest point of nearly every user, as the data stored in it is essential, increased phone access security has been achieved by using biometric authentication modalities on these mobile devices. Here, the biometric modules that are most commonly used for authentication and how they are shared, the process of access and the weaknesses of each of these biometric modalities will be elaborated. Also indicate what are the potential attacks and problems that can be encountered in each of the biometric authentication methods on mobile devices.

In this paper, I propose the drafting and implementation of the Health System Strategy, based on ICT solutions, as well as in this document will be proposed the steps for the establishment and development of the health information system, which provides access to electronic health records to support decisionmaking in healthcare institutions, including human resource management, patient management, disease management, health status management, pharmaceutical management, and participation in open market The health information system is the establishment of a standardized interchange platform of patient's data, through network infrastructure, hardware equipment, and software solutions. Below is the strategy, I will try to visualize the architecture of the eHealth Information System. For us, it is very important to emphasize the life cycle of different entities and their interactions in the ecosystem of all the interoperable architecture, which is the basis for the proposed strategy. The information system architecture feasibility analysis is based on a personalized medical system, and interoperable between different modules or data.

The UBT Knowledge Center initiative extends the founding vision of national development through higher education. Since local knowledge, identity, and learning are necessarily situated, Kosovar students, faculty, staff, and administrators serve as topical experts and international educators from Sweden and the United States serve as design facilitators. Participatory design commenced in April 2017 when international faculty from Sweden and the United States co-taught a graduate level course, Information Systems Analysis, Design, and Modelling, at the Pristina campus. Working with UBT administrators, directors, managers, and librarians, students worked in teams to co-design three essential parts of a holistic Knowledge C...

At its essence, the Center aims to make local knowledge visible through furthering discovery of and access to research content produced by academic students and university professors on institutional, local and international levels. This paper reports on conceptual exploration of this institutional idea during spring semester 2017 in a graduate course on systems thinking and methodology. Using active learning pedagogy to improve local situations, an international teaching team facilitated student and stakeholder engagement in participatory design activities using soft systems methodology tools and techniques. Course evaluation outcomes revealed students' improved levels of knowledge and development of insights. In addition, their course work demonstrated their advanced understanding of systems thinking and its application. Furthermore, students expressed high motivation to learn more about other human-centred theories and participatory design tools. In considering the value of the University's knowledge vision, they were especially enthusiastic about its implications for furthering national democratic development in Kosovo and regional economic growth in southeastern Europe.

Therefore, electronic scrap (E-scrap) encompasses a broad and growing range of electronic devices ranging from large household appliances such as refrigerators, air conditioners, hand-held cellular phones, personal stereos, and consumer electronics to computers. The reuse of E-scrap is mainly limited in the separation of valuable materials, but there is another opportunity in using the e-scrap robots by combining them with renewable energy sources, and this way to build self-sustainable robots, which are cost effective and building them can be very functional for different universal needs. Self-sustainable robot (SSR) from e-scrap using renewable energy, has a solar panel to power it and to make him self-sustainable, it enables the robot to move through campus grounds and search for best angle to sunbathe and this way to collect energy. It can be used in different ways form greeting, giving out flyers, as an information robot to give information on ongoing conferences agenda, workshops etc. SSR, will provide a very good learning experience and show that robotics and renewable energy can go hand in hand and serve as a gateway to start getting SSR from e-scrap.

The vast majority of these schemes and systems are available even in Kosovo and their well-functioning is enabled by a broad scope of training and certification. Certification as well as quality assurance in the field of ICT is overwhelmingly important, particularly for employing the ICT industry referring it as the core of sustainable development in the professional career. We are aware that in Kosovo is still evident the phenomenon which is related to the lack of transparency concerning the qualifications. In this point of view, we have reasoned out that these education authorities such as training providers and certification organizations are eager to establish a close cooperation and a carry out a full-fledged and fruitful process of exchanging their experiences, aiming to build up a mechanism which would contribute to acknowledgements of these qualifications. However, our research is putting the emphasis on the labor modalities and the knowledge acquired by the most innovative practices of ICT, particularly in different sectors such as private businesses, state agencies, banking sector and governmental organizations. This study is developed in Kosovo and may serve as a case study for describing the approach of technology in education, respectively the impact and importance of professional education in a developing country.

One of the robot family built for University needs is Beggar Robot. Begging is a practice of asking a favor with no return back, favors can be monetary but also gifts, food etc. The idea behind beggar robot comes from a Slovenian artist Sašo Sedlaček, who build some of these robots in different countries but the technical solution and the building of this particular robot was done by us. The robot was built from old computer materials such as the computer cases to build the body, CD rom to build the hands, and old monitor to replace the face, and cheap electronics and open source control boards. Based on fact that building robots with almost zero cost we can conclude will provide a very good learning experience and also serve as a gateway to get into building robotics from e-scrap.

Chatterjee et al. recently introduced the first two typotolerant password checkers, which improve usability at no security cost but are technically complex. We look at the more general problem of computing an edit distance between two strings without having direct access to those strings — by storing the equivalent of a hash. We propose a simpler algorithm for this problem that is asymptotically quasi-optimal in both bits stored and exchanged, at the cost of more computation on the server.
