In this article, transport properties of a single-wall carbon nanotube having chirality (4, 0), connected to copper, gold and graphene electrodes, have been investigated. Electronic structures have been analyzed using the density functional theory calculator. Transport properties of the devices formed by interfacing of single-wall carbon nanotube and electrodes are computed using the nonequilibrium Green's functional method coupled with density functional theory approach. Contact effects due to metal-carbon nanotube interface have significant impact on transport properties of charge carriers. Therefore, transport properties have been critically analyzed with the help of transmission spectra, differential conductance and conductance plots and I-V characteristics. From these results, it has been concluded that formulation of the electrode material is not the single-factor responsible for creating conduction problems. Along with the electrode material, interface position of metal-carbon nanotube configuration and heterostructure contacts are also responsible in influencing transport phenomenon. In this way, varying the contact geometry is found to play an important role in integrated circuit interconnect technologies for exploring the transport properties. Gold is best among all three simulated contact electrodes, and for low-power applications, graphene can be next choice over an applied bias range of 21 to +1 V. Atomistix software tool has been used to analyze transport properties of interconnect models. © IMechE 2013.

The most important factor in quality measurement of any technique or system is the efficiency. The hyper spectral images are the complex ones those are taken from the low resolution cameras. These images are often degraded in the acquisition process due to the integrated so many different noises in it. These can include various types of noises as impulse noise, Gaussian noise, deadlines and stripes etc. This paper defines new hybrid image restoration method based on Linear Discriminative Analysis (LDA) and Low Rank Matrix Recovery (LRMR). The proposed approach works in two phase, first it converting an image into number of patches and treating each patch as a separate image, performance can be measured out and that patches induced in LRMR framework In second phase, for further improvement in image quality LDA approach is used. © 2015 IEEE.

Two checkpointing approaches i.e., coordinated checkpointing and times based checkpointing are widely used in the literature of MDSs. Coordinated checkpointing protocols uses the less checkpoints and domino free but have large coordinated message overheads as processes synchronize by exchanging coordinated message. Time based approach has minimum coordinated messages overheads cost but has high checkpointing cost as it requires large number checkpoints than minimum. Hence coordinated checkpointing approach have minimum checkpointing cost than time based approach but higher coordinated message overheads cost which increases the checkpointing overheads. In this paper, we design an efficient time coordinated checkpointing algorithm which uses time to indirectly coordinate to minimize the number of coordinated message transmitted through the wireless link and reduces the number of checkpoints nearest to the minimum. The algorithm is non-blocking and minimum process. © 2013 Springer Science+Business Media.

Fault tolerant Resource consumption in Desktop grid is a motivational area in research. The present research paper focuses on the dimensions of Fault Tolerant resource usage especially in area of available computational power. Desktop grid resources are accountable for generation of computational power. Alchemi Desktop middleware is useful for collection of computational power on diverse machines in Microsoft window based environment. Failure and Fault in execution side can create serious problem, in addition to a direct impact on computational power in Real Time Environment. In the Environment of faults, control on the available computational power is very necessary in grid middleware. This problem has not been addressed so far. Alchemi Desktop Grid Middle ware provide manual Procedure for control of computational power in Real Time Environment. There is no automated mechanism available for controlling the processing power in alchemi desktop grid. This Research work has proposed, designed & developed automated framework for Alchemi Grid middleware. Framework can take control on available computational power in Real Time Environment at Time of Fault in execution processes. Testing for the framework is done in Real Time environment. Results after test show that framework gives quick response for controlling available computational power. Framework is able to detect defective process machine and correct fault in milliseconds which will cooperative to maintain level of available computational power In Real time Environment. This Research work has tried to eliminate Manual Procedure for controlling computational power by using automated Method for quick action in case of execution side faults. © 2015 IEEE.

An experiment was initiated in 2008 to evaluate the impact of irrigation regimes on germination and growth patterns of seedlings of Prosopis cineraria in the arid areas of Thar, India. Seeds collected from dried pods of P. cineraria were sown in polybags placed in nursery beds. Different irrigation regimes were provided to different beds and data regarding germination and growth were recorded to study natural regeneration. The study revealed that irrigation regimes significantly affected the germination and growth of P. cineraria under nursery conditions. The germination rate declined as the irrigation regime shifted from a daily to a fortnightly basis. Height of the seedlings also declined with a decrease in the intensity of irrigation. Thus, it can be concluded that germination and growth of seedlings of P. cineraria under nursery conditions can be enhanced by providing irrigation at regular intervals. © 2012 Beijing Forestry University and Springer-Verlag Berlin Heidelberg.

This paper presents the design and implementation of fuzzy based controller for the general form of two-link planar robotic manipulator. Also for comparative analysis, the conventional controllers; proportional-derivative (PD), proportional-integral-derivative (PID) and computed torque control are implemented on the same system under same conditions. The comparative analysis of the results demonstrates that the fuzzy logic controller is best among all the controllers and the simulation results confirm that the system can track the desired trajectory. Computer simulation results on a two-link planar robotic manipulator are presented to show tracking capability and effectiveness of the proposed control schemes. The simulations have been carried out using Matlab. © 2013 IEEE.

The new heterobimetallic [Mg(II)-Ti(IV)]-μ-oxoisopropoxide was synthesized on treatment of magnesium acetate with titanium(IV) isopropoxide in refluxing decalin in 1:2 molar ratio and characterized by liberated isopropanol, elemental, spectral (IR, 1H and 13C NMR, and mass), thermal analysis, and molecular weight data. The reactions of [Mg(II)-Ti(IV)]-μ-oxoisopropoxide compound with β-diketones in different molar ratios (1:1-1:4) yielded mono to tetra derivatives [{MgO 2Ti2(OPr)6-nLn}] (where n is 1-4 and L = acetylacetonate/benzoylacetonate anion)] of the μ-oxo complex and were characterized by elemental, liberated isopropanol, and spectral analysis (IR and 1H and 13C NMR). These studies revealed interesting facets in support of plausible structures of the parent compound and its β-diketonates. © TÜBITAK.

New salicylate derivatives of heteronucleic-μ-oxoisopropoxide [SnO 2AlB(OPri)2] have been synthesized by the thermal condensation of μ-oxoisopropoxide and methyl/ethyl/phenyl/phenyl ethyl salicylates in different molar ratios (1:1-1:2) yielding the compounds of the type [SnO2AlB(OPri)2-n(RSAL)n] (where n is 1-2 and RSAL = salicylate anion), respectively. The complexes have been characterized by elemental, spectral (IR, 1H, 13C, 27Al, 119Sn and 11B NMR), thermal and molecular weight measurement. The complexes are hydrolysed by hydrothermally assisted sol-gel technique and gave hydrolyzed product. Thermal studies of these products are made which favor the formation of multicomponent oxides. The studies reveal that salicylate derivatives are polymeric in nature and low susceptible to hydrolysis as compared to parent compound and may prove excellent precursors for the mixed metal oxides. © 2013 Chemical Society of Ethiopia.
