Title: Adaptive E-learning Content Design and Delivery Based on Learning Styles and Knowledge Level<br/><br/>Authors: Vassileva, Dessislava<br/><br/>Abstract: The possibility of adaptive learning content delivery in e-learning systems is one of the important factors for highly improving theirquality. Therefore, the application field of adaptive e-learning is relevant and significant. This article presents the main results of a PhD thesis examining various aspects of this area. The aim of the dissertation is to propose a model and a platform architecture of an adaptive e-learning system and a corresponding prototype to be designed, implemented and tested in experimental conditions. On one hand, the developed prototype will assist a learner in accessing and using learning resources which are adapted according to his/her personal characteristics (in this case his/her learning style and level of knowledge). On the other hand, it will facilitate the author of the learning content and course instructor in the creation of appropriate learning objects and applying them to the suitable pedagogical strategies.<br/><br/>Description: ACM Computing Classification System (1998): K.3.1, K.3.2.BPMN Analysis of Public Procurement

Title: BPMN Analysis of Public Procurement<br/><br/>Authors: Semerdjieva, Maria; Krastev, Evgeniy<br/><br/>Abstract: This paper formulates a realistic case study of a public procurement process, where the national legal system is taken in consideration.Business Process Modeling Notation (BPMN) is used for encoding processes related to the analysis of public procurement tasks. Critical elements in the public procurement process that affect time, quality and cost are identified at the organizational, process execution and system levels. The main phases of public procurement are described and problems related to each phase are distinguished. A BPMN collaboration diagram is used to show how different participants in a process are related and interact with each other.Choreography diagrams of the latest version of BPMN are being used to model the abstract behavior of the participants in business interactions for the purpose of providing a standard mapping to the Business Process Execution Language for Web Services (BPEL) and enable the execution of this behavior.<br/><br/>Description: ACM Computing Classification System (1998): D.0, D.2.11.Time–Harmonic Behaviour of a Cracked Piezoelectric Solid by BIEM

Title: Time–Harmonic Behaviour of a Cracked Piezoelectric Solid by BIEM<br/><br/>Authors: Marinov, Marin; Rangelov, Tsviatko<br/><br/>Abstract: Time–harmonic behaviour of a cracked piezoelectric finite solidis studied by nonhypersingular traction Boundary Integral Equation Method(BIEM). A numerical solution for Crack Opening Displacement (COD) andStress Intensity Factor (SIF) is obtained by using Mathematica. Severalexamples are presented to demonstrate the dependence of the solution onthe crack position.<br/><br/>Description: ACM Computing Classification System (1998): J.2, G.1.9On Blocking Sets in Affine Hjelmslev Planes

Title: Application of Wavelet Decomposition to Document Line Segmentation<br/><br/>Authors: Laskov, Lasko<br/><br/>Abstract: In this paper an approach to document line segmentation is presented. The algorithm is based on a wavelet transform of the horizontalprojective profile of the document image. The projective profile is examined as a one-dimensional discrete signal which is decomposed using the pyramidal wavelet algorithm up to a precise scale, where local minima and maxima are discovered. These local extrema, projected into the input signal, correspond to the spacing between document lines and to the pivots of the lines. The method has been tested on a broad set of printed and handwritten documents and proven to be stable and efficient.<br/><br/>Description: ACM Computing Classification System (1998): I.7, I.7.5.
