This paper studies a generalized version of the well-known page replacement problem. It assumes that page sizes and page fault penalties are nonuniform. This problem arises in distributed information systems, in particular ...

Distributed systems greatly benefit from caching. Caching data objects of

variable size and cost poses interesting questions that have

been researched for the past ten years. As a result, a few good algorithms ...

The newest generation of Implantable Medical Devices (IMDs) employ wireless communication with a nearby base station in order to provide better treatment and monitoring of the patients. However, a wireless connection opens ...

Pipeline FFT processors are used in mobile communication systems and in

particular in OFDM-based systems. This paper presents a method for power analysis of

pipeline FFT processors. This method applies to ...

Pipeline FFT processors are used in mobile communication systems and in particular in OFDM-based systems. This paper presents a method for delay analysis of pipeline FFT processors. This method applies to various architectures ...

A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS

implementation is presented. Out of the three modules in a common full-adder circuit, we

have replaced one with a new design, and optimized ...

A novel blind watermarking technique based on QR decomposition in still images is proposed. The method is implemented in wavelet domain and its robustness has been evaluated against some image processing attacks and the ...

In this paper an estimation

technique for the data hiding capacity in

biometric images is presented. We consider the

QSWT algorithm for data hiding in biometric

images and investigate the effect ...
