Advances on the continued fractions method using better estimations of positive root bounds
(2007)We present an implementation of the Continued Fractions (CF) real root isolation method using a recently developed upper bound on the positive values of the roots of polynomials. Empirical results presented in this paper ... 
Applying constructivism for interactive educational software: A research based design, implementation and evaluation method
(2004)We have designed, developed and evaluated the educational software entitled "Interaction between objects" within the framework of social constructivism on the basis of the data issued from a preceded research with teachers ... 
An autodidactic programming curriculum application for early education: Pilot studies and improvement suggestions
(2012)Informal learning is a research area not fully explored yet [1], but interest in out of classroom learning methods and settings is currently increasing [2], [3]. In parallel to that, the advent of Internet, which allows ... 
Black hole search with finite automata scattered in a synchronous torus
(2011)We consider the problem of locating a black hole in synchronous anonymous networks using finite state agents. A black hole is a harmful node in the network that destroys any agent visiting that node without leaving any ... 
Computations in modules over commutative domains
(2007)This paper is a review of results on computational methods of linear algebra over commutative domains. Methods for the following problems are examined: solution of systems of linear equations, computation of determinants, ... 
Computing scientometrics in largescale academic search engines with MapReduce
(2012)Apart from the wellestablished facility of searching for research articles, the modern academic search engines also provide information regarding the scientists themselves. Until recently, this information was limited to ... 
Concise and accurate solutions to halfspace binarygas flow problems defined by the McCormack model and speculardiffuse wall conditions
(2004)An analytical version of the discreteordinates method (the ADO method) is used to establish concise and particularly accurate solutions to the viscousslip and the halfspace thermalcreep problems for a binary gas mixture. ... 
Continuous replica placement schemes in distributed systems
(2005)The Replica Placement Problem (RPP) aims at creating a set of duplicated data objects across the nodes of a distributed system in order to optimize certain criteria. Typically, RPP formulations fall into two categories: ... 
Decoupling of singular systems via PD feedback
(1996)The problem of inputoutput decoupling of singular systems via proportional plus derivative (PD) feedback is solved. The necessary and sufficient condition for the problem to have a solution is established. A special ... 
Design architecture of a data driven environment for multiphysics applications
(2003)The design architecture of a multidisciplinary problemsolving environment (MPSE) for supporting an efficient prediction capability for the response of continuous interacting systems under multiphysics conditions is ... 
Detecting IEEE 802.11 MAC layer misbehavior in ad hoc networks: Robust strategies against individual and colluding attackers
(2007)Selfish behavior at the Medium Access (MAC) Layer can have devastating side effects on the performance of wireless networks, with effects similar to those of Denial of Service (DoS) attacks. In this paper we consider the ... 
Dialoguebased personalized reflective learning
(2004)The WebBased Reflective Tutorial Dialogue System (WReTuDiS) is a system for personalized learning of historical text comprehension on the Web. The system offers a two level open interface: tutor level and learner level. ... 
Distributed online schedule adaptation for balanced slot allocation in wireless ad hoc networks
(2004)We propose an algorithm for design and on the fly modification of the schedule of a wireless ad hoc network for provision of fair service guarantees under topological changes. The primary objective is to derive a distributed ... 
Distributed resource allocation algorithms for peertopeer networks
(2008)In peertopeer networks, each peer plays the role of client and server. As server, it receives content requests made by other peers and needs to decide on what basis and to what extent it will satisfy these requests by ... 
Disturbance decoupling of singular systems via PD feedback
(1999)The problem of disturbance decoupling of singular systems via proportional plus derivative (PD) feedback is solved. The necessary and sufficient condition for the problem to be solvable is established as a rank condition ... 
Effective problem solving through fuzzy logic knowledge bases aggregation
(2015)Cooperative problem solving has attracted great interest in the research community. A number of nodes can cooperate to reach a common goal which is the solution to a specific problem. Through a team effort, nodes try to ... 
An exact solution algorithm for maximizing the fleet availability of an aircraft unit subject to flight and maintenance requirements
(2013)Flight and Maintenance Planning (FMP) of mission aircraft addresses the question of which available aircraft to fly and for how long, and which grounded aircraft to perform maintenance operations on, in a group of aircraft ... 
A framework for MAC protocol misbehavior detection in wireless networks
(2005)The pervasiveness of wireless devices and the architectural organization of wireless networks in distributed communities, where no notion of trust can be assumed, are the main reasons for the growing interest in the issue ... 
Implementing replica placements: Feasibility and cost minimization
(2007)Given two replication schemes Xold and Xnew, the Replica Transfer Scheduling Problem (RTSP) aims at reaching Xnew, starting from Xold, with minimal implementation cost. In this paper we generalize the problem description ...
