Exploring The Role Of Sentiments In Identification Of Active And Influential Bloggers, Mohammad Alghobiri, Umer Ishfaq, Hikmat Ullah Khan, Tahir Afzal Malik

UBT International Conference

The social Web provides opportunities for the public to have social interactions and online discussions. A large number of online users using the social web sites create a high volume of data. This leads to the emergence of Big Data, which focuses on computational analysis of data to reveal patterns, and associations relating to human interactions. Such analyses have vast applications in various fields such as understanding human behaviors, studying culture influence, and promoting online marketing. The blogs are one of the social web channels that offer a way to discuss various topics. Finding the top bloggers has been a …


Microsimulation Models For Simulating Pathways Of Patients With Mental Diseases, Andreas Bauer, Felix Breitenecker, Christoph Urach Nov 2015

Microsimulation Models For Simulating Pathways Of Patients With Mental Diseases, Andreas Bauer, Felix Breitenecker, Christoph Urach

UBT International Conference

Predicting demand for care is necessary to provide sufficient capacities in hospitals and enable better planning to cope with challenges like changes in the structure of the population. Emphasis in this work is put on the analysis of the data and on the parametrization of a simulation model for the paths of patients with mental diseases through the health care system. Survival analysis and model selection methods are used for this purpose. Data on patients and their treatments is analyzed with methods of survival analysis. Different methods for modelling the survival and hazard function are presented and compared. Hereby, the …


The Importance Of Big Data Analytics, Eljona Proko Nov 2015

The Importance Of Big Data Analytics, Eljona Proko

UBT International Conference

Identified as the tendency of IT, Big Data gained global attention. Advances in data analytics are changing the way businesses compete, enabling them to make faster and better decisions based on real-time analysis. Big Data introduces a new set of challenges. Three characteristics define Big Data: volume, variety, and velocity. Big Data requires tools and methods that can be applied to analyze and extract patterns from large-scale data. Companies generate enormous volumes of polystructured data from Web, social network posts, sensors, mobile devices, emails, and many other sources. Companies need a cost-effective, massively scalable solution for capturing, storing, and analyzing …


10 W Dc-Dc Converter Based Led Driver Circuit Design, Ö. Faruk Farsakoğlu, H. Yusuf Hasrici, Ibrahim Çelik Nov 2015

UBT International Conference

Considering the total amount of energy consumed in the world, energy used in lighting is of utmost importance. For this reason, systems used in lighting should be energy efficient, and mıre efficient lighting elements should be preferred. LED, as a solid-state lighting system, is more energy efficient than the lighting systems with conventional lighting elements. Some of the LEDs used in solid-state lighting systems are named as standard 5mm LEDs and power LEDs. Because power LEDs have more light efficiency than standard 5 mm LEDs, they are produced as an alternative to conventional light sources. Power LEDs draw much more …


Implementation Of The Aodv Routing In An Energy-Constrained Mesh Network, Altin Zejnullahu, Zhilbert Tafa Nov 2015

Implementation Of The Aodv Routing In An Energy-Constrained Mesh Network, Altin Zejnullahu, Zhilbert Tafa

UBT International Conference

Wireless sensor networks (WSNs) compose the fundamental platform for a number of Internet of Things (IoT) applications, especially those related to the environmental, health, and military surveillance. While being autonomous in power supply, the main challenge in node’s processing and communication architecture design remains the energy efficiency. However, this goal should not limit the main functionality of the system which is often related to the network coverage and connectivity. This paper shows the implementation of the Ad-hoc On-demand Distance Vector (AODV) routing algorithm in an XBee based platform. As shown, the network can achieve low power consumption per node primarily …


Internet Of Things: From Applications, Challenges And Standardization To Industry Implementations, Xhafer Krasniqi Nov 2015

Internet Of Things: From Applications, Challenges And Standardization To Industry Implementations, Xhafer Krasniqi

UBT International Conference

The Internet of Things that is defined as anything that can be accessible anytime and anywhere provides connectivity to different objects and sensors around us and which will enable the transfer of different data between these objects and devices. A thing in the Internet of Things can be any natural or man-made object that can be assigned an IP address with a capability to exchange date over a network. There is a huge number of applications of IoT to benefit users, such as health monitors, smart homes, connected cars etc. If everything around us is connected and information about these …


Bounty Techniques For Web Vulnerability Scanning, Tanzer Abazi, Mentor Hoxhaj, Edmond Hajrizi, Gazmend Krasniqi Nov 2015

Bounty Techniques For Web Vulnerability Scanning, Tanzer Abazi, Mentor Hoxhaj, Edmond Hajrizi, Gazmend Krasniqi

UBT International Conference

With the advancement of technology and the raising of massive amount of data, the used techniques for data security are continually a challenge. This paper contributes on identifying the gaps and evaluating security level on web portals hosted or managed by Republic of Kosovo institutions or businesses, whose data privacy and security could be a big business concern. The results have been obtained from real case scenario, where 25 security researchers have contributed in white hack activities. These activities, were part of a one day conference called. “The DAY when hacking is legal”, held in Pristine.


Security Concerns Of New Alternative Telecommunication Services, Arbnora Hyseni, Krenare Pireva, Miranda Kajtazi Nov 2015

Security Concerns Of New Alternative Telecommunication Services, Arbnora Hyseni, Krenare Pireva, Miranda Kajtazi

UBT International Conference

With the advancing new era of communication, the so-called era of ‘being always online’ many providers offer their services for free. In that sense a small company or a virtual company becomes a huge competitor for different traditional telecommunication providers. Using the same services such as: voice calls, video calls, chat and similar services, the internet technology has made huge changes how users make use of such services . Instead of using these services, users shall install applications that are specialized for offering these services via applications, such as: Viber, WhatsApp, Facebook, Google Talk etc.. During the installation and update …
