As Design Complexity is growing and Size of the individual components i.e mosfets shrinks, it led to the need for increased clock speeds, to do faster computation and propagate the clock to different subsystems of the chip. The clock to be routed must be free from clock skew and jitter. The alternate method for reducing power requirement is use of multi-Vdd i.e more than one supply voltage depending on the requirement ,without reducing the speed in an system on chip. For this, Level Converters are required. Level converters based on Multi-Vdd are proposed in this paper. The proposed level converters are compared with the existing standard level converters. Compared to the Existing Level Converters, the proposed level converters offers significant power saving and increased speed. In this paper ,180nm MOSFETs are used. For high performance and Low power design, different types of level converters are analyzed using Cadence Tools. © 2016 IEEE.

As Integrated Circuits are more complex, the need of supplying accurate and synchronized clocks to all the circuits becomes increasingly difficult. In some cases, more than one clock cycle is required to perform a predictable action. Clock Circuits are responsible for proportionate fraction of the power dissipation of a chip and are important in terms of performance. In integrated circuit, multiple supply voltages are utilized for reducing the power consumption by a sub- circuit. A sub circuit supply voltage is used to generate an output signal at a Lower Supply Voltage for another sub circuit and is generated from a higher supply voltage, and this achieves reduction of the power consumption by the sub circuit. Since an output signal generated by the sub circuit is a lower voltage signal, at the front stage of an output circuit, a level conversion circuit transform the level of this signal into a signal for the higher external supply voltage and Vice versa . In this paper for high performance and Low power design, two different types of level converters are proposed and the effect of temperature on process parameters is analyzed using Cadence Tools. © 2016 IEEE.

In this paper, we developed an efficient approach for the automated analysis of microarray images. The proposed approach consists of three steps: pre-processing, gridding and segmentation. Initially, the microarray images are preprocessed by hill climbing algorithm and gridding is applied to accurately identify the location of each spot while extracting spot intensities from the microarray images. In the segmentation stage, we developed an efficient Enhanced Fuzzy C-means (EFCMC) algorithm. The advantages of the proposed clustering algorithm compared with the conventional clustering techniques in segmentation of microarray image are given as: (1) it effectively detects the absent spot since the inclusion of neighborhood pixel information. (2) It is quite independent of the various noises (3) the detection of accurate spot can be done. By taking these advantages, the proposed approach effectively segmented the microarray images with preserving the image details. The proposed method is tested and evaluated using the Microarray image Database and the results confirmed the efficiency of the proposed approach. © 2011 Springer-Verlag.

A link analysis procedure is the one of the suitable technique for extracting relational models from relational data bases based on random walk model through the database defining Markov chain having as many states as elements related to database. One of the fundamental limitation of the link analysis is that relational data base could contain too many turned off elements, in which situation link analysis strategy is almost ineffective. Moreover, it is clearly not always simple to draw out a graph from a relational data source, especially when the database is large. So we propose develop Fuzzy Link based Analysis for extracting relationships in cluster database. The objective of our proposed approach is to recover not only the elements strictly submission with the restrictions of the SQL question, but also the components that almost adhere to these constraints and are therefore near to the focus on components. We will also assess the suggested technique on real cluster data sources. Our experimental results show efficient clustered documents from predefined datasets using Extended Boolean retrieval design in Fuzzy Link Based Analysis. © Research India Publications.

Although efforts have been made to fix the issue of clustering particular details via group outfits, with the results being aggressive to traditional methods, it is noticed that these methods unfortunately produce any details partition based on imperfect details. The actual ensemble-information matrix provides only cluster-data point interaction, with many entries being left unidentified. The paper provides an research that indicates this issue degrades the quality of the clustering outcome, and it provides a new link-based approach, which enhances the traditional matrix by finding unidentified records through similarity between groups in an collection. In particular, an efficient link-based criterion is suggested for the actual likeness evaluation. Afterward, to obtain the ultimate clustering outcome, a chart dividing technique is used to a calculated bipartite chart that is formulated from the enhanced matrix. Trial outcomes on several real details sets recommend that the suggested link-based method almost always outperforms both traditional clustering methods for particular details and well-known group collection techniques. © Research India Publications.

Resistance spot welding process parameters are optimized to improve spot weld quality. The experimental studies are conducted under varying force of electrode, welding current flow and its time duration. The spot weld quality characteristics are shear tensile strength and direct tensile strength has been considered. Signal to noise ratio was used to establish optimal process parameters. To authenticate the contribution percentage of experimental results against specified confidence level ANOVA was used. Verification trials show that it is feasible to improve the quality characteristics considerably. The investigational repercussions proved the effectiveness of the applied Taguchi method for improving spot weld quality. © 2015 Elsevier Ltd.

The instantaneous growth of mobile apps in mobile markets elevating the concerns on the protection of user's sensitive data in Smartphone's. The Majority of apps in all mobile markets are gathering the data which is insignificant to the app functionality. The mobile app collects the data of the user either users' sensitive data or device data by using orthodox permission control policy. This Permission policy in apps takes acceptance of user for installing an app and user has only one option to accept all permissions to continue the installation of app. In this work we proposed a framework PLANT which is Permission Leakage AvoidaNce Through Filteration for identifying data leakage done by mobile apps by using permissions. Finally framework gives the knowledge to the user to deny if there are any irrelevant permissions required by the app based on its functionality. © 2016 The Authors.

This paper describes the High capacity energy efficient Dynamic MAC protocol (HCEEDMAC) for WCDMA wireless multimedia networks to allocate system resources to multimedia users for QoS provisioning and for high resource utilization. The protocol is designed to support high capacity, Energy efficient and high throughput by using interference control and congestion control. High throughput is achieved by Dynamic MAC protocol (DMAC) using contention based scheduling. High capacity and Energy efficiency are achieved by using Adaptive Power Control technique (APC) which reduces the interference level and Adaptive Call Admission control (ACA) mechanism which controls the congestion by reducing the call blocking probability. By simulation results, we show that our proposed HCEEDMAC protocol achieves high capacity, Energy efficient and high throughput for multimedia data transmission. © 2013 IEEE.

During production of calibrated (sized) ore, more than 50 % of the generated fines and rejects (Slimes) cannot be directly utilised in iron making due to its unfavourable granulometry, low iron content, high alumina and silica content. Approximately 10–20 % of the process plant input is discarded as slimes into slime ponds/tailing dams. Tailing dams are now considered as a threat due to hazardous nature and acute shortage of land for storing. More over these slimes also pose threat to the environment. Recovery of iron values from slimes results in economic benefit by utilisation of waste as a resource and minimizes the land requirement, surface degradation, ground water pollution, destruction of forests. These slimes after beneficiation are agglomerated (Pelletisation) and can be used as burden for the blast furnace. This research work presents the route for beneficiation of slimes by removing gangue in the slimes to an acceptable level to produce hot metal through blast furnace route. Research has been carried out effectively and efficiently to utilise the iron ore slimes from the slime ponds of Donimalai iron ore mine. The slime sample from tailing pond of Donimalai iron ore mine was collected and transported to R&D Centre, NMDC Limited, Hyderabad. The ‘as received’ slime sample assayed 49.40 % Fe, 13.51 % SiO2, 8.44 % Al2O3, 5.16 % loss on ignition and all other trace elements were within the critical limits. The ‘as received’ sample contains around 7 % moisture. It has a bulk density of 1.74 t/m3 and specific gravity of 3.7. Screen assay analysis was carried out with the ‘as received’ sample. Optimisation studies were carried out for desliming by using hydro-cyclone. Hydro-cyclone underflow was subjected to magnetic separation. It is possible to produce a concentrate which assayed 65.93 % Fe, 1.45 % SiO2, 1.94 % Al2O3 and 1.56 % loss on ignition with a yield of 45.18 % with a recovery of 60 % iron values. © 2015, The Indian Institute of Metals - IIM.

This paper presents a novel approach using Equal incremental fuel cost (λ) and Tie line matrix for solving the Multi-Area Economic Dispatch (MAED) problem with tie line loss. Incremental fuel cost (λ) concept is introduced in this paper in order to evaluate the power to be transferred through tie lines from one area to another area in more economically and then Tie line matrix has been adopted to calculate the tie line power flow between the areas connected with tie line. The proposed approach has been tested on 4-area system with four generators in each area. The simulation results of the proposed method have been compared with the existing methods in literature and it is found that the results obtained from the present technique are better than the existing methods. © 2015 IEEE.
