Algorithms for energydriven agent placement in wireless embedded systems with memory constraints
(2011)The agent programming paradigm provides an easy to use framework for coding embedded applications in a pervasive environment. Under this model, applications are structured as mobile agents that can be flexibly installed ... 
Analysis and optimization of dynamically loaded porous metal sliding bearings under conditions of elastohydrodynamic lubrication
(2007)Purpose  This paper aims to develop a simulating model of a journal porous metal bearing under elastohydrodynamic conditions and combined (radial, friction and thermal) load distribution and to carry out structural ... 
Application of the integromoment method to steadystate twodimensional rarefied gas flows subject to boundary induced discontinuities
(2008)The computational efficiency of the integromoment method for solving steadystate twodimensional rarefied gas flows is investigated. The twodimensional boundary driven flow of a single gas in a cavity is used as a model ... 
Applications of singularvalue decomposition (SVD)
(2004)Let A be an m x n matrix with m greater than or equal to n. Then one form of the singularvalue decomposition of A is A = UT SigmaV, where U and V are orthogonal and Sigma is square diagonal. That is, UUT = Irank(A), VVT ... 
Are Computer Science and Information Technology still masculine fields? High school students' perceptions and career choices
(2008)This study investigated Greek high school students' intentions and motivation towards and against pursuing academic studies in Computer Science (CS), the influence of the family and the scholastic environment on students' ... 
An assessment of two fundamental flat triangular shell elements with drilling rotations
(2000)An approach for adding drilling rotations to the constant strain triangle, such that the added rotation stiffness contributes a minimum to the strain energy of the triangle is presented. The element is combined with a ... 
Asymptotic optimality of the RoundRobin policy in multipath routing with resequencing
(2006)We consider a model of a multipath routing system where arriving customers are routed to a set of identical, parallel, single server queues according to balancing policies operating without state information. After completion ... 
CDNsim: A Simulation Tool for Content Distribution Networks
(2010)Content distribution networks (CDNs) have gained considerable attention in the past few years. Hence there is need for developing frameworks for carrying out CDN simulations. In this article we present a modeling and ... 
A classification system based on a new wrapper feature selection algorithm for the diagnosis of primary and secondary polycythemia
(2013)Primary and Secondary Polycythemia are diseases of the bone marrow that affect the blood's composition and prohibit patients from becoming blood donors. Since these diseases may become fatal, their early diagnosis is ... 
Classification tree based protein structure distances for testing sequencestructure correlation
(2008)A methodology for testing the correlation between the sequence and structure distances of proteins is proposed. Structure distances were derived by applying a forward growing classification tree algorithm on defined ... 
Combined prediction of Tat and Sec signal peptides with hidden Markov models
(2010)Motivation: Computational prediction of signal peptides is of great importance in computational biology. In addition to the general secretory pathway ( Sec), Bacteria, Archaea and chloroplasts possess another major pathway ... 
Comparative calculation of irrigation networks using Labye's method, the linear programming method and a simplified nonlinear method
(2010)The designating factors in the design of branched irrigation networks are the cost of pipes and the cost of pumping. They both depend directly on the hydraulic pump head. It is mandatory for this reason to calculate the ... 
Comparison of quadratic and nonlinear programming (QP and NLP) optimization models in groundwater management
(2004)This project is concerned with the comparison of two algorithms used in groundwater management models based on Quadratic Programming (QP) and Nonlinear Programming (NLP) models,. A quadratic objective function is used and ... 
Component mode synthesis techniques for finite element model updating
(2013)Deterministic and Bayesian finite element (FE) model updating techniques are computationally very demanding operations due to the large number of FE model reanalyses required. Component mode synthesis techniques are ... 
Computer aided analysis of viscous film flow along an inclined wavy wall
(1999)The steady, laminar flow of a Newtonian liquid along an inclined wavy wall is studied in a twodimensional numerical experiment using the Galerkin finite element method. The dimensionless NavierStokes equations are solved ... 
Computer simulation based selection of optimal monomer for imprinting of triOacetiladenosine in polymer matrix: vacuum calculations
