the main objective of this paper is to argue how the mobile phones have transformed the iranian lifestyle and how the arrival of mobiles has been a catalyst for revolting behavior, and has launched a new consumer behavior and has changed our relationships. the paper explains how the people's behavior has developed a whole new social code in iran. it is argued that the social value of being able...

We present a new differential compression algorithm that combines the hash value techniques and suffix array techniques of previous work. The term ‘‘differential compression’’ refers to encoding a file (a version file) as a set of changes with respect to another file (a reference file). Previous differential compression algorithms can be shown empirically to run in linear time, but they have ce...

The subject of this dissertation are universal lossless data compression algorithms. It is a very important field of research as the data compression allows to reduce the amount of space needed to store data or to reduce the amount of time needed to transmit data. This dissertation presents lossless data compression algorithms as well as most of well-known nowadays reversible data transforms th...

At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...

Reducing image files will be an important procedure when we transmit files across networks (Wiseman, Schwan & Widener, 2004). or when we would like to archive libraries. Usually, JPEG can remove the less important data before the compression; hence JPEG will be able to compress images meaningfully, which produces a huge difference in the transmission time and the disk space. The processing time...

Trace-driven simulation is a simple, fast, and convenient approach to simulate computer architecture for power consumption, throughput, CPU time, and other factors. However, trace-driven simulation requires a massive storage space to save the trace files of benchmark programs. Therefore, an important task is how to design a compression method that reduces the storage space of trace files effici...

Introduction: Coenzyme Q10 is a powerful antioxidant that has the ability to reduce the damage caused by oxidative stress and is predominantly found in the inner mitochondrial membrane. This study was conducted to determine the effect of coenzyme Q10 on neuropathic pain in an animal model of spinal cord injury. Methods: In order to induce neuropathic pain, thoracic segments of the spinal cor...

In recent years, customer lifetime value (CLV) has gained increasing importance in both academia and practice. While many advanced techniques have been proposed, the recency/frequency/monetary value (RFM) segmentation framework, and its related probability models, remain a CLV mainstay. In this article, we demonstrate the de_ciency in RFM as a basis for summarizing customer history (data compre...
