A new embedded controller for data acquisition and control applications
(ISCIS, 1999)Developing high performance data acquisition and control systems takes better tools than the industry normally provides. As the most common controllers, PLCs can be still weak in many applications, and especially they are ... -
Determination of dose profile data with film dosimetry
(IEEE, 2001-10)Almost all external radiotherapy planning systems use dose profile data. There are various methods to measure these profiles. Direct measurements with semiconductor detectors are widely used. But this method takes lots of ... -
Neuro-fuzzy controller in real-time feedback schedulers
(Izmir Institute of Technology, 2002-06)Traditional scheduling algorithms worked on closed and highly predictable environments. However present day systems need to work in more open and unpredictable environments; such as mobile robots, on-line trading, ... -
İzmir Yüksek Teknoloji Enstitüsü'nün bilgisayar ağı için bir servis kalitesi uygulaması
(Türkiye Bilişim Derneği, 2002-09)Günümüzün gelişen bilgisayar ağları ve bu ağlarda oluşan trafik tiplerindeki çeşitlilik, Servis Kalitesi için büyük gereksinim doğuracak nitelikte sıkışıklıklar meydana getirmektedir. Nitekim, Servis Kalitesi’nin ne olduğu ... -
Bir ağ yönetim sistemi: GuardiLAN
(Türkiye Bilişim Derneği, 2003-09)Bilgisayar ağlarındaki hızlı gelişime rağmen ağ yönetim sistemleri bu gelişimin gerisinde kalmaktadır. Ağların hızla gelişmesi, ağda oluşan trafik tiplerindeki çeşitlilik, ve kaynaklardaki kısıtlılık Servis Kalitesi ve ... -
Stability properties of adaptive real-time feedback scheduling: A statistical approach
(Nessuna, 2004-03)This paper focuses on the statistical analysis of an adaptive real-time feedback scheduling technique based on imprecise computation. We consider two-version tasks made of a mandatory and an optional part to be scheduled ... -
Gerçek-Zamanlı uyarlamacı görev planlaması tekniğinin RT-Linux’ta uygulanması
(Türkiye Bilişim Vakfı, 2005)Bu çalışma kesinleşmemiş hesaplamalar yöntemine dayalı olan gerçek-zamanlı geribesleme denetimli bir görev planlama tekniğinin ("Real Time Feedback Control Scheduling") Gerçek zamanlı Linux (Rt-Linux) üzerindeki uygulamasını ... -
Crympix: Cryptographic multiprecision library
(Springer, 2005)This paper delineates the results gained throughout the development of a cryptographic multiprecision1 integer library, CRYMPIX. To obtain the know-how for cryptographic computation and thus being able to create the high ... -
A cluster-based dynamic load balancing middleware protocol for grids
(Springer, 2005)We describe a hierarchical dynamic load balancing protocol for Grids. The Grid consists of clusters and each cluster is represented by a coordinator. Each coordinator first attempts to balance the load in its cluster and ... -
Serial and parallel multilevel graph partitioning using fixed centers
(Springer, 2005)We present new serial and parallel algorithms for multilevel graph partitioning. Our algorithm has coarsening, partitioning and uncoarsening phases like other multilevel partitioning methods. However, we choose fixed nodes ... -
Dynamically adaptive partition-based data distribution management
(IEEE, 2005)Performance and scalability of distributed simulations depends primarily on the effectiveness of the employed data distribution management (DDM) algorithm, which aims at reducing the overall computational and messaging ... -
Multilevel static real-time scheduling algorithms using graph partitioning
(Springer, 2005)We propose static task allocation algorithms for the periodic tasks of a distributed real-time system. The cyclic task consists of task threads which may communicate and share resources. A graph partitioning process and a ... -
Merging clustering algorithms in mobile Ad Hoc networks
(Springer, 2005)Clustering is a widely used approach to ease implementation of various problems such as routing and resource management in mobile ad hoc networks (MANET)s. We first look at minimum spanning tree(MST) based algorithms and ... -
Optimal control for real-time feedback rate-monotonic schedulers
(Springer, 2005)This paper presents an optimal control scheme for a real-time feedback control rate-monotonic scheduling (FC-RMS) system. We consider two-version tasks composed of a mandatory and an optional part to be scheduled according ... -
Implementation of a cluster based routing protocol for mobile networks
(Springer, 2005)We show the implementation and the simulation results of a hierarchical, cluster based routing protocol for mobile ad hoc networks using Parallel Virtual Machine (PVM). The network represented by a graph is partitioned ... -
Mobile join operators for restricted sources
(Hindawi Publishing, 2005)We consider the problem of query execution when there is limited access to the relations, i.e. when binding patterns require values to be specified in order to get data from the relation. This problem is common in virtual ... -
Feedback control static scheduling for real-time distributed embedded systems
(IEEE, 2005-11-21)This paper presents an implementation of feedback control strategy on distributed static scheduling. The static schedule is created taking into account the average execution times of the tasks. Feedback control algorithm ... -
Intelligence analysis modeling
(IEEE, 2006)Intelligence is the process of supporting the policymakers in making their decisions by providing them with the specific information they need. Intelligence analysis is the effort of extracting the nature of intelligence ... -
A replication-based fault tolerance protocol using group communication for the grid
(Springer, 2006)We describe a replication-based protocol that uses group communication for fault tolerance in the Computational Grid. The Grid is partitioned into a number of clusters and each cluster has a designated coordinator that ... -
Performance evaluation of group communication architectures in large scale systems using MPI
(Springer, 2006)Group communication is an important paradigm for fault tolerance in large scale systems. We describe various group architectures as pipelined, hierarchical, daisy and hypercube groups each consisting of separate clusters, ...
