A Summary Of Classification And Regression Tree With Application, Adem Meta
UBT International Conference
Classification and regression tree (CART) is a non-parametric methodology that was introduced first by Breiman and colleagues in 1984. CART is a technique which divides populations into meaningful subgroups that allows the identification of groups of interest. CART as a classification method constructs decision trees. Depending on information that is available about the dataset, a classification tree or a regression tree can be constructed. The first part of this paper describes the fundamental principles of tree construction, pruning procedure and different splitting algorithms. The second part of the paper answers the questions why or why not the CART method should …

Fuzzy Logic Controlofgantry Crane System, Betim Shabani
UBT International Conference
The use of gantry crane systems for transporting payload is very common in industrial application. However, moving the payload using the crane is not an easy task especially when strict specifications on the swing angle and on the transfer time need to be satisfied. To overcome this problem, an intelligent gantry crane system had been introduced. Fuzzy logic controllers were adopted, designed and implemented for controlling payload position as well as the swing angle of the gantry crane. Fuzzy logic defines rules that determine the behavior of the system using word descriptions instead of mathematical equations also fuzzy logic control …

Improving Non-Native English Students’ Communicative Competence And Collaboration Skills Through Virtual Simulations, Alisa Sadiku
Improving Non-Native English Students’ Communicative Competence And Collaboration Skills Through Virtual Simulations, Alisa Sadiku
UBT International Conference
Knowing how to communicate in the target language is the main goal of most language learners. Furthermore, it is very challenging for teachers to bring real world communication experiences in classroom settings where English is not the native language. Hence, in this paper I explore the role of virtual simulations in promoting communicational and collaboration opportunities to non-native speakers of English. In my research, I describe how virtual worlds improve communicative and collaborative skills of non-native speakers of English. Moreover, I investigate how virtual worlds can create a learner centered environment where students take control of their own language production. …

Traditional Mathematics And New Methods Of Teaching Through Programming Together With Students, Robert Kosova, Teuta Thanasi, Lindita Mukli, Loreta Nakuçi Pëllumbi
UBT International Conference
We are used to the traditional methods of teaching mathematics. The textbook, the blackboard and a chalk have been for centuries a wonderful part of teaching. And, they always will be. Traditional teaching methods of mathematics are a wonderful legacy of our educational system that have educated generations of teachers, engineers, administrators, managers, leaders, and economists. American universities websites, the video- lectures of the best professors of well-known disciplines such as statistics, operational research, number theory, algebra, game theory, show impressing large blackboards, all over the auditor's walls. We always will need and admire traditional mathematics. But, beyond the lessons, …

Some Propositions About Inverse Semigroups, Osman Hysa, Arben Reka
UBT International Conference
The inverse semigroups are semigroups studied by many algebraists. In this paper we will formulate and prove some other propositions on these semigroups. So we will prove two propositions concerning the closure of a subsemigroup of a given inverse semigroup S, within the meaning introduced by Schein in 1962, two propositions on the group congruence on a normal subsemigroup of the inverse semigroup S, and a proposition about closed subsemigroup assertion of an inverse semigroup S.
Some Issues In The Testing Of Computer Simulation Models, David J. Murray-Smith
Some Issues In The Testing Of Computer Simulation Models, David J. Murray-Smith
UBT International Conference
The testing of simulation models has much in common with testing processes in other types of application involving software development. However, there are also important differences associated with the fact that simulation model testing involves two distinct aspects, which are known as verification and validation. Model validation is concerned with investigation of modelling errors and model limitations while verification involves checking that the simulation program is an accurate representation of the mathematical and logical structure of the underlying model. Success in model validation depends upon the availability of detailed information about all aspects of the system being modelled. It also …
