Redundancy estimates for the Lempel-Ziv algorithm of data compression
The problem of non-distorting compression (or coding) of sequences of symbols is considered. For sequences of asymptotically zero empirical entropy, a modi0cation of the Lempel–Ziv coding rule is o1ered whose coding cost is at most a 0nite number of times worse than the optimum. A combinatorial proof is o1ered for the well-known redundancy estimate of the Lempel–Ziv coding algorithm for sequenc...

A Wireless Sensor Network (WSN) is an increasingly important mechanism for enabling continuous monitoring and sensing of physical variables like temperature, humidity etc. The tiny sensor nodes are powered by low capacity batteries. As the WSNs are usually deployed in remote areas, battery replacement becomes difficult. To minimize the power consumption in WSN, the data compression schemes play...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

Carl Jung said, 'Collective unconscious' i.e. we are all connected to each other in some way or the other via our DNA. In frequent cases there are four bases in a DNA. They are a (Adenine), c (Cytosine), g (Guanine) and t (Thymine). Each of these bases can be represented by two bits as 2 powers 2 =4 i.e. a – 00, c – 01, g – 11 and t – 10 respectively, although this choice is random. So redundan...
