High Performance FIFO Design for Processor through Voltage Scaling Technique

Abstract: Green computing is making revolution by bringing high speed processor with less power consumption. Our paper is based on this philosophy. Objectives: To come out High Performance FIFO for processor by minimizing the power consumption. Methods/Statistical Analysis: To make FPGA based design of FIFO we used voltages and frequency scaling techniques. Keeping voltage constant at 2.3 volt we varied frequency from 20MHz to 250MHz and for other experiment we kept the frequency constant and varies voltages from 1volt to 2.3 volt. Findings: The power consumption is reduced to 95.79% on voltage scaling where as there is a 4.38% less power consumption on frequency scaling. Application/Improvements: It will surely help in futuristic processor development.

Energy Efficient CRC Design for Processor of Workstation, and Server using LVCMOS

Abstract: In our work we have designed CRC using the LVCMOS IO standards which are stands for Low Voltage Complementary Metal Oxide Semiconductor. In this work we have worked with four kinds of LVCMOS (LVCMOS 12, LVCMOS 15, LVCMOS 18, LVCMOS 25). For LVCMOS 12 when we scaled down the frequency form 50GHz to 10 GHz we found 64.41% reduction in total power. For LVCMOS 15 when we change down the frequency form 50GHz to 10GHz we found 67.58% reduction in total power. For LVCMOS 18 when we scaled down the frequency form 50GHz to 10 GHz we found 69.54% reduction in total power. In last when we reduced the frequency form 50GHz to 10GHz in LVCMOS 25 we found 64.41% reduction in total power. Our CRC design is implemented on Virtex-6 FPGA family.

We have designed our FIFO on 28 nm kintex-7 FPGA family

SSTL IO Based WLAN Channel Specific Energy Efficient RAM Design for Internet of Thing

Abstract: Now days in area of computer science Green computing is creating revolution by bringing some new digital component with less power consumption. Our research work is created on this idea. In this paper our objective is to come up with High Performance RAM design for IOT based processor by reducing the power consumption. For calculating total power consumption of FPGA based RAM we used five WLAN frequencies (900 MHz, 2.4GHz, 3.6GHz, 5GHz, 5.6GHz) and calculated Clock, Logic, Signals, IOs, Leakage power at four different IOs standard (SSTL 135, SSTL15, SSTL18_I, SSTL18_II). In experiment we found that if we will use the SSTL135 instead of SSTL18_II IO standard then we can reduced power consumption by 8.69% at 900MHz, 10.74% at 2.4MHz, 11.80% at 3.6MHz, 12.86% at 5MHz and 13.29% at 5.9MHz. We think that the application of this design will definitely help to design in futuristic IOT based processor development.

Diversity and phylogenetic profiling of niche-specific Bacilli from extreme environments of India

Abstract: The diversity of culturable, aerobic and heterotrophic Bacillus and Bacillus-derived genera (BBDG) was investigated in various extreme environments (including thermal springs, cold deserts, mangroves, salt lakes, arid regions, salt pans and acidic soils) of India. Heat treatment followed by enrichment in different media led to a total of 893 bacterial isolates. Amplified ribosomal DNA restriction analysis (ARDRA) using three restriction enzymes AluI, MspI and HaeIII led to the clustering of these isolates into 12–74 groups for the different sites at 75 % similarity index, adding up to 559 groups. Phylogenetic analysis based on 16S rRNA gene sequencing led to the identification of 392 bacilli, grouped in two families, Bacillaceae (89.03 %) and Paenibacillaceae (10.97 %), and included 13 different genera with 75 distinct species. It was found that among the thirteen genera, nine (Bacillus, Halobacillus, Lysinibacillus, Oceanobacillus, Pontibacillus, Salinibacillus, Sediminibacillus, Thalassobacillus and Virgibacillus) belonged to Bacillaceae and four (Ammoniphilus, Aneurinibacillus, Brevibacillus and Paenibacillus) belonged to Paenibacillaceae. Novel isolates tolerant to low and high pH and temperature, salt and low moisture were identified. The major outcome of the present investigation was the identification of niche-specific species and also the ubiquitous presence of selected species of BBDG, which illustrate the diversity and pervasive nature of BBDG in extreme environments.

Energy-Efficient UART Design on FPGA Using Dynamic Voltage Scaling for Green Communication in Industrial Sector

Abstract: In the present scheme of the world, the problem of shortage of power is seen across the world which can be a vulnerability to various communication securities. The scope of proposed research is that it is a step towards completing green communication technology concepts. In order to improve energy efficiency in communication networks, we designed UART using different nanometers of FPGA, which consumes the least amount of energy. This shortage is happening because of expanding of industries across the world and the rapid growth of the population. Therefore, to save the power for our upcoming generation, the globe is moving towards the concept and ideas of green communication and power-/energy-efficient gadget. In this work, a power-efficient universal asynchronous receiver transmitter (UART) is implemented on 28 nm Artix-7 field-programmable gate array (FPGA). The objective of this work is to reduce the power utilization of UART with the FPGA device in industries. To do this, the same authors have used voltage scaling techniques and compared the results with the existing FPGA works.

Diversity of endophytic actinomycetes in mandarin grown in northern Thailand, their phytohormone production potential and plant growth promoting activity

Abstract: The rapid expansion of mandarin (Citrus reticulata L.) production areas with high agrochemical input in the highland areas of northern Thailand has resulted in negative effects in terms of production, environment, soil quality, and public health. The use of microorganisms as plant growth promoters is an alternative method to reduce agrochemical input. Thus, we studied the diversity of endophytic actinomycetes in mandarin and their potential as plant growth promoters. A total of 252 endophytic actinomycete isolates were recovered from mandarin. Based on spore chain morphology, cell wall type, and 16S rRNA gene sequence, the isolates were classified into six genera: Streptomyces, Nocardia, Nocardiopsis, Spirillospora, Microbispora and Micromonospora. The most frequent isolates recovered were members of Streptomyces (85.3%). Selected isolates (64 isolates) from these genera were evaluated for their indole-3-acetic acid (IAA) production potential in a medium with 2 mg mL−1 tryptophan, and all the sel...

Impact of phosphate solubilizing bacteria on growth and yield of maize

Abstract: Soil microorganisms are supportive in the transformation of soil phosphorus (P) and are thus an important component of the soil P cycle. These are effective in releasing P both from inorganic and organic pools of total soil P through their respective solubilizing and mineralizing abilities. To evaluate this, five promising strains of PGPR (PS-01 (Burkholderai sp.), PS-12 (Bacillus sp.), PS-32 (Pseudomonas sp.), PS-41 (Flavobacterium sp.) and PS-51 (Pseudomonas sp.)) capable of solubilizatio n of both organic and inorganic phosphorus as investigated under in vitro conditions were evaluated in a pot trial for their rhizosphere phosphatase activity and mineralization potential of organic P in soil, plant growth and yield at different farmyard manure (FYM) levels i.e. 0, 8 and 16 Mg ha -1 . These bacterial strains were also monitored for other attributes like chitinase activities and root colonization ability in addition to phosphatase activity, auxin production and ACC-deaminase activity. In response to inoculation with these selected rhizobacteria, significant increases in plant height, root length, shoot dry weight, root dry weight and grain yield were observed which were up to 16, 11, 42, 29 and 33%, respectively, over uninoculated control in the presence of FYM at 16 Mg ha -1 . Similarly, there were significant increases in the rhizosphere phosphatase activity, mineralization of organic P and soil available P which were 189, 185 and 62% higher than uninoculated control in the presence of FYM, respectively. The study demonstrated that the use of PGPR having multifaceted beneficial traits would be highly effective for improving growth and yield of crops.

Assessment of functional and genetic diversity of aerobic endospore forming Bacilli from rhizospheric soil of Phyllanthus amarus L.

Abstract: Fifty two aerobic and endospore forming Bacilli (AEFB) strains were recovered from rhizospheric soil of Phyllanthus amarus. Morphological, biochemical and molecular characterization by 16S rDNA gene sequencing has shown that these bacterial strains belong to six different genera of AEFB i.e. Bacillus, Brevibacillus, Lysinibacillus, Paenibacillus, Terribacillus and Jeotgalibacillus. Analysis of their PGP activities has shown that 92.30 % strains produced indole acetic acid hormone, 86.53 % of the strains solubilized Phosphate and 44.23 % strains produced siderophore. Chitinase production activity was shown by 42.30 % of the strains and 21.15 % of the strains produced 1-amino cyclopropane-1-carboxylate (ACC) deaminase. 46.15 % of isolates have shown antagonistic activity against common fungal pathogen of the plant i.e. Corynespora cassiicola. Among all of the isolated strains B. Cereus JP44SK22 and JP44SK42 have shown all of the six plant growth promoting traits tested. B. megaterium strains (JP44SK18 and JP44SK35), Lysinibacillus sphaericus strains (JP44SK3 and JP44SK4) and Brevibacillus laterosporus strain JP44SK51 have also shown multiple PGP activities except ACC deaminase production activity. In the present study bacterial strain belonging to genera Jeotgalibacillus sp. JP44SK37 has been reported first time as a member of rhizospheric soil habitat and has also shown PGP activities. It can be concluded that Rhizosphere of P. amarus has harboured a good diversity of AEFB bacterial strains having a lot of biofertilizing and biocontrol abilities.
