NiCuZn ferrite nanopowders and polycrystalline bulk samples were prepared by wet chemical (citrate) method followed by sintering at temperatures lower than those for conventional solid-state ceramic route. The citrate method results in nano-powders. The addition of copper promotes sintering, and results in grain-growth during sintering, even at a low temperature. Composite thick films of desired thickness were prepared by die casting the ferrite mixed with a polymer in different weight ratios. The dielectric properties of the polycrystalline NiCuZn ferrite and their composite thick films were investigated at radio- and X-band microwave frequencies. Dielectric and magnetic losses are estimated to be appreciably low, even at microwave frequencies. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

In this paper, we have we have introduced a new intelligent soft-computing method of neutrosophic search with ranks and a new neutrosophic rank sets for neutrosophic relational data model (NRDM). Essentially the data and documents on the Web are heterogeneous; inconsistency is unavoidable in Web mining. Using the presentation and reasoning method of our data model, it is easier to capture imperfect information on the Web which will provide more potentially valued-added information. In Bio-informatics there is a proliferation of data sources. Each research group and each new experimental technique seems to generate yet another source of valuable data. But these data can be incomplete and imprecise, and even inconsistent. We could not simply throw away one data in favor of other data. So now we can represent and extract useful information from these data as a challenge. Thus it is a kind of an intelligent search for match in order to answer imprecise queries of the lay users. Our method, being an intelligent soft-computing method, will support the users to make and find the answers to their queries without iteratively refining them by trial and error. This important issue of closeness cannot be addressed with the crisp mathematics. That is why we have used the Neutrosophic tools. Neutrosophic-search method could be easily incorporated in the existing commercial query languages of DBMS to serve the lay users better. So in this Paper Authors are suggesting NRDM and Rank Sets to solve the imprecise query based on Rank Neutrosophic search which is a combination - Neutrosophic Proximity search and α-Neutrosophic-equality Search. © 2010 IEEE.

This Paper aims to reduce the read time as well as to increase the SNM and stability of the SRAM cell during read operation. A different 7T cell with single bit line is proposed to increase the SNM and stability within the memory core. A 4 × 4 array is constructed using single ended 7T cell to show the feasibility of the proposed SRAM cell. A 16 Bit SRAM operating at 1 v supply voltage is demonstrated in 45 nm CMOS process. Its total power consumption is reduced by more than 90% of the conventional design. This 7T cell has lower leakage current due to single bit line and transmission gate at feedback. As a result it is suitable for low power consumption application especially battery operated gadgets. Copyright © 2013 American Scientific Publishers All rights reserved.

Low power design is the industry buzzword these days in present chip design technologies. CMOS technology continues to drive the reduction in switching delay and power while improving area density. However, the transistor miniaturization also introduces many new challenges in Very Large Integrated (VLSI) circuit design, such as sensitivity to process variations and increasing transistor leakage. This paper focus is to reduce leakage power consumption of an 8 kbit SRAM by employing techniques like power gating. The main technique used in power gating is the use of sleep transistor. In our design we have chosen a stack-based implementation. In this paper, leakage power is measured by simulating a 1 Kb SRAM array. Leakage power is measured when each SRAM cell holds a logical '1' or '0'. Simulations were done in CADENCE using 45 nm Technology. Leakage power of 10T SRAM cell (Sleepy) = 155.4 nW. Leakage power of 6T SRAM cell (Sleepy) = 375.3 nW. Copyright © 2013 American Scientific Publishers.

Metal complexes of Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) with a new Schiff base derived from 2-acetylpyrrole and o-phenylenediamine are reported. The complexes have been characterized using chemical analysis, spectroscopic methods (IR, UV-VIS, 1H NMR), conductometric and magnetic data. According to these data, an octahedral geometry for metal (II) complexes are proposed. Antibacterial activity of the ligand and its metal complexes were studied against to Staphylococcus aureus, Bacillus subtilis, Salmonella typhi and E. coli.
