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 ...
Optimization of integer-pel motion estimation for H.264 video encoding on tms 320c6416t digital signal processor
(Işık Üniversitesi, 2007-12-03)
Video processing is used in many applications such as broadcast television and home entertainments. Video applications have been revolutionized by the advent of digital TV and DVD-video players. The standardization of video ...
Cluster based sensors scheduling in a target tracking application with particle filter method
(Işık Üniversitesi, 2006)
In multisensor applications, management of sensors is neccessary for the classification of data they produce and for the efficient use of sensors as well. One of the most important aspects in sensor management is the sensor ...
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 ...
Evolving strategies for web crawler
(Işık Üniversitesi, 2009-05-06)
With the rapid growth of Internet and Internet-based information, it becomes the largest and publicly accessible data source in the world. Every day millions of information available so to achieve information becomes harder. ...
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. ...
New approaches for channel estimation in wireless communications
(Işık Üniversitesi, 2006-03-10)
This thesis first proposes a conputationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorthm for the orthogonal frequency division multiplexing OFDM systems in unkonown ...
Circuit models with mixed lumped and distributed elements for passive one-port devices
(Işık Üniversitesi, 2006-01-23)
In this thesis, to model measured data obtained from an actual passive one-port device, a circuit modeling method with mixed lumped and distributed elements is proposed. Namely, measured data is modelled by means of its ...
