An extension of the binary buddy system, called “tertiary buddy system" for dynamic storage allocation is presented in this work. Tertiary buddy system allows block sizes of 2 and 3.2 whereas the original binary buddy system allows only block sizes of 2. This extension is achieved at an additional cost of two bits per block. Simulation of the proposed algorithm has been implemented in C program...

This paper is concerned with the problem of finding bounds for the norm of lower triangular matrix operators from [Formula: see text] into [Formula: see text], where [Formula: see text] is the Cesàro weighted sequence space and [Formula: see text] is a non-negative sequence. Also this problem is considered for lower triangular matrix operators from [Formula: see text] into [Formula: see text], ...

We establish a sufficient condition for a block sequence in the Schlumprecht space S to have a subsymmetric subsequence, and prove the existence of an uncountable family of subsymmetric and mutually non-isomorphic block sequences in S.

We first include a result of the second author showing that the Banach space S is complementably minimal. We then show that every block sequence of the unit vector basis of S has a subsequence which spans a space isomorphic to its square. By the Pe lczyński decomposition method it follows that every basic sequence in S which spans a space complemented in S has a subsequence which spans a space ...

Background: To assess MRI in diagnosing endometriotic lesions, emphasizing T2*weighted imaging efficacy. Materials and Methods: This prospective study of 48 females (22-38 years, average 29.6) clinically suspected of endometriosis from September 2009 to April 2012. MRI was performed with a 1.5 T imager (Siemens) with a body array coil. T1, T2 and T2* weighted (2D-FLASH) sequences were obtained ...

Space-time block code (STBC) has a good BER performance. In 3GPP FDD specifications, Space Time Transmit Diversity (STTD) employs STBC to maintain orthogonality between the two antennas in order to avoid self-interference in fading channels. However, the capacity of multi-user STBC systems is still severely affected by multiple access interference (MAI) and inter-path interference (IPI). Fortun...

A factorial experiment was conducted to evaluate the impact of super absorbents and organic wastes of rice, olive marc, vermicompost and farmyard manure on the soil water holding capacity and the growth of plant based on randomized complete block design with 13 treatments at two irrigation intervals 5 and 10 days. The olive saplings with same heights and better appearances were planted...
