Performance Analysis Of Java Persistence Api Providers, Besart Pllana
UBT International Conference
Nowadays, fast and accurate access to data is very important. Usually data is managed and processed through software applications. In recent years, the most preferred programming model by most application developers is Object Oriented Programming (OOP) where data is represented through objects. These data must be persistent and therefore needs to be stored, and storage can be done on a variety of databases. The most common databases are Relational Database Management Systems (RDBMS). While persistence of objects in RDBMS is limited by object-relational mismatch which is the inconsistency of the direct interaction between two components based on different approaches, OOP …

Nb-Iot: A Network Slice For Massive Iot, Xhafer Krasniqi
UBT International Conference
Network virtualisation is a concept that has been around for some time now, but the concept of network slicing is more recent and only started to be mentioned in the context of 5G. In essence, network slicing is a specific form of network virtualisation that enables sharing of physical resources by multiple logical network slices used to serve different applications and use cases. One such a use case would be to allocate network resources to small things, e.g. sensors and very low power consumption objects. To allow these small objects access to network resources or to a slice of such …

Morphological Parsing Of Albanian Language: A Different Approach To Albanian Verbs, Iir Çollaku, Eşref Adali
UBT International Conference
The very first step when processing a natural language is creating a morphological parser. Verbs in Albanian language are the most complex area of inflection. Besides irregular verbs, the ways in which the regular verbs change their form while being inflected are hardly definable, and the number of exceptions is huge. In this paper, a different approach to Albanian verbs is made. Unlike traditional classification, based on the inflection themes they take, verbs are classified into different verb groups. This way, the inflection process looks clearer and more regular, as the affix remains the only changeable part of the inflected …

Definition, Validation And Comparison Of Two Population Models For Austria, Martin Bicher, Barbara Glock, Florian Miksch, Niki Popper, Günter Schneckenreither
UBT International Conference
In this work we present two structurally different mathematical models for the prognostic simulation of Austria’s population: A time-continuous, macroscopic system dynamics approach and a time-discrete, microscopic agent-based approach. Both models were developed as case studies of a series of population concepts in order to support models for decision-support in Austria’s health care system. In the present work we want to focus on the definition, the parametrisation as well as especially the validation process of both population-models. The latter was of special interest as it included a cross-model validation with Statistics Austria’s own prognostic model SIKURS.
