Data collection and analysis on vanet
(Işık Üniversitesi, 2009-02-01)
The communication between devices is provided by wireless networks and it is growing rapidly, dependent on the needs. Wireless networks strike the attention of people throughout the world, and the ad hoc network is part ...
A learning object harvesting model and a sample application
(Işık Üniversitesi, 2008-03-06)
The aim of this thesis is to enable harvesting of Learning Objects which are embedded in web pages. Two main challenges have been identified which are interoperability and semantics. For this purpose, several learning ...
Security of chaotic cryptosystems
(Işık Üniversitesi, 2008)
In this thesis, we tried to show the weaknesses of chaotic cryptosystems. We break four chaos-based cryptosystems and proved our attacks. In our first cryptanalysis, we broke a cryptosystem based on two dimensional chaotic ...
Spline based neural networks
(Işık Üniversitesi, 2005-06)
In this thesis, we applied the Catmull-Rom splines and B-splines to the neural networks models, which are Multi Layer Perceptrons, Elman Networks, and Locally Recurrent Neural Networks, as adaptive activation functions. ...
Cost sensitive learning algorithms
(Işık Üniversitesi, 2008)
This thesis studies the cost sensitive learning algorithms that calculate the class learning algorithms errors and costs. Data mining is the automated extraction of hidden predictive information from databases that can be ...
Distributed iterative cluster localization in wireless sensor networks
(Işık Üniversitesi, 2009-01-07)
We designed a distributed algorithm for iterative cluster localization. Because this algorithm is especially designed for large scale networks, increase in the number of sensor nodes has no ine ciency e ect on sensor node ...
Performance and security issues in e-payment systems: pay on-line case
(Işık Üniversitesi, 2006-06)
In this thesis, we report an experience on Performance and Security issues in E-Payment systems. We develop an E-Payment system which covers all introduced performance and security measures written in this thesis. We also ...
Performance analysis of static agent architecture with centralized matchmaking
(Işık Üniversitesi, 2005)
Large- scale network environments such as the internet possess the characteristics of distributed data, distributed access and distributed control. This gives users a powerful mechanism for building and integrating large ...
Enterprise manager tool
(Işık Üniversitesi, 2005)
In this thesis we develop a new Enterprise Manager Tool with transformation data to Excel sheet capability. This is a user friendly tool.This tool gives user to access databases and database objects such as tables,views,stored ...
A new priority based packet scheduler with deadline considerations
(Işık Üniversitesi, 2006)
Quality of Services (QoS) issues have become a focus point of research on Next Generation Networks (NGNs). In order to supply the various QoS requirements for different kinds of applications, new packet scheduling policies ...
