Synthesis and characterization of Pure and Indium doped sno2 nanostructures by sol-gel methods[ ]


We report simple methods to synthesize Pure Tin oxide nanostructures and Indium doped Tin oxide Nanostructures without using catalysis with less complicity. Nanosized SnO2 particles have been synthesized by a simple sol-gel method. The obtained tin oxide powder has been characterized using X-ray powder diffraction, scanning electron microscope, and DC conductivity studied. The result shows that there is the formation rutile type (tetragonal) structure in nanometric range. This was done by adding SnCl4.2H2O in Ethanol and adding of HCl and NH4OH at appropriate ratio and formed nano powder is annealed for 300oC for 2h. We also synthesized the In/SnO2 Nanostructures by Sol-Gel method by adding 0.11 atomic % and 0.24 atomic% of Indium to SnO2. The obtained powder is annealed at 300oC for 2h. In (NO3)3 is added to SnCl4.2H2O to get indium doped tin oxide nanostructures. These nanocomposites are characterized by XRD, SEM, EDX and DC Conductivity was studied in the temperature range 25°C to 150°C and it was observed that conductivity of SnO2 is increased by adding Indium dopant.

THE ROLE OF ENERGY IN THE JAPAN ECONOMY[ ]


The purpose of this research is to investigate how energy resources affect Gross Domestic Product or economic growth of Japan, using data over a period from 2000 to 2014. The Cobb-Douglas production function was used for two models using macroeconomic indicators. These indicators are GDP, energy production, capital, net energy import and energy consumption. GDP is the dependent variable and energy production and capital are the independent variables in the first model. GDP again is the response variable and net energy import and energy consumption are the predictor variables for the second model. A regression analysis was run on both models to know the relationship between all the variables. The empirical results showed a positive relationship between GDP and energy production, capital and net energy import. However, the results showed a negative correlation between GDP and energy consumption. The result also showed Japan highly reliability on overseas countries for its energy supply and this dependency even increased after the Fukushima accident in March, 2013.

DESIGNING OF FISCAL REGIME FOR OIL AND GAS SECTOR IN UZBEKISTAN[ ]


Today a comprehensive range of fiscal tools existing to policymakers to design a fiscal regime for the oil and gas sector that will attract investment at the same time provide a reasonable share of economic interest for the country. Some countries rely on production-based levies to ensure a steady stream of revenue to the state budget, while others put greater emphasis on profit-based levies to minimize distortions. The conducted study uses documental analysis methods and shows that most countries have mixed (profit-based and production-based) levies. Fiscal terms declared by a country reflect the negotiating strength and experience of the country, potential reserves, and the track record of previous projects. Potential fiscal income may be lowered to compensate for specific high costs of extracting oil, commercial or political risk premia the study is revealed.

Classifying Students 2nd Level at National Crypto Institute with Vertex Discriminant Analysis and Kernel Discriminant Analysis[ ]


Discriminant analysis is a multivariate technique to classify the observations into the known groups and one or more new observations are classified into one of the known groups based on the discriminant function. Classical discriminant analysis, also known as Fisher discriminant analysis, assumes that the data from each group have homogeneous variance-covariance matrices. If the data does not meet the assumption, we can use Vertex Discriminant Analysis (VDA) or Kernel Discriminant Analysis (KDA) to perform discriminant analysis. In this paper, we compare the performance of both methods in classifying "data". In classifying students based “Grade Point Achievent (GPA)”, the data that we was use are final scores of subject in first semester and scores of psikotest. With the training data about 70%, the results show that 71.7% of the data was correctly classified using VDA and 37.7% of the data was correctly classified using KDA. For testing data, VDA have 43.5% data was correctly and KDA have 52.2% data was correctly, so VDA is better than KDA for validations and KDA is better than VDA for predictions in this case.

Compression Efficiency improvement of HEVC Encoder by Introduction of First Pass Encoding[ ]


High Efficiency Video Coding (HEVC/H.265) is the next generation video compression standard, the successor of Advanced Video Coding (AVC/H.264). HEVC is expected to improve the compression efficiency by 50% compared to its predecessor. The introduction of a first pass encoder results in dual pass encoder with the pre-encoder feeding the information about the video frame to the second pass. This article discusses an implementation of a pre-encoder module, which analyses the given video, performs motion estimation on a sub-sampled image and provides information about the video frame to the actual encoder. Approximate motion estimation information will help the actual encoder to perform accurate motion estimation, which improves the overall coding efficiency.

Simultaneous Logic Operation Using Optical Shadow Casting Technique for 3D Scheme[ ]


This paper represents the fastest operations in parallel processing of logical units, free space interconnection using the non-polarized characteristics of light. Different new algorithms are exploited in the design of optical computing modules using encoded optical shadow casting (OSC) scheme. In advanced VLSI system 3D IC is one of the hosts of 3D integration schemes that use the z direction to gain the higher electrical performance. In order to achieve more functionality within a compact space, 3D IC is structured by bracing silicon wafers and interconnects them vertically using through-silicon via (TSV) technique, as such they can behave like a system on chip (SOC). As this is a new technology, people will face new hardship or obstacles including cost, yield, heat, design complexity and interconnects however lack of standards. Interconnection problem is relatively dreadful in this 3D IC system whereas we can possess a free space interconnection 3D system, the generalized OSC design algorithm which realizes a functional truth table is used to design parallel logic gates. In this paper we evolve a new design scheme for parallel processing of logical units that shallows less power, less area and massive improvement in parallel interconnection. This design of parallel OSC demonstrates a completely novel computing system as it is capable of triggering to compute parallel logical operation of the two bit binary variables. The design algorithm for identity the source patterns, input encoding pattern and output decoder with possible parallel implementation are also presented. This design efficiency improves up to 77.78% compared to the conventional designalgorithms.

ESDAS: Explorative Spatial Data Analysis Scale to predict spatial structure of landscape[ ]


Cartographic scale definition of the hydrographic features is critical to display the geospatial data as computer aided maps. Discovering the landscape type that provides geographic context is significant to define cartographic scale. Extensive coverage of the spatial gradients are generally used to distinguish the landscape type. The variation or change over from one type to other type landscape are with limited outliers and not instantaneous. Hence the classification of the landscape types is challenging. An exploratory spatial data analysis scale to learn and predict the landscape types in spatial data is described. This research defined a meta-heuristic scale to perform deep learning that extracts patterns from labeled spatial data of landscape types and further classifies the given unlabeled spatial data in to divergent landscape types. Cross validation and misclassification rate analysis are used to evaluate the proposed model. The paper explored the proposed explorative scale and its impact on the selection of landscape regions. The experiments evinced the scalability and robustness of the proposed explorative scale sensibility to recognize landscape diversity.

Comparative Use of Cement and Katsi to Stabilize Laterite as a Liner in Containment Facility[ ]


Solid waste management has recently dominated the environmental scene in developing countries, everyday nearly three thousand tons of solid waste is generated in each state thereby causing environmental degradation. This research investigates the use of cement, and Katsi admixture to stabilize laterite used as a liner in containment facility. A trial pit of 1m3 at a waste disposal site was dug and soil sample were collected. The natural soil was subjected to test in accordance with BS 1377(1990). The sample was prepared by adding either cement or Katsi to the collected soil, at varying percentage. The geotechnical properties of unstabilized soil sample shows that the soil has a low to medium plasticity; its specific gravity of 2.44 indicates that the soil needs improvement for it to meet the range of value stipulated for clay minerals. Also the unconfined compressive strength UCS of the soil was observed to be 286.0 KN/m2, and coefficient of permeability K was found as 1.39 x 10-5 cm/s. Katsi was observed to have improved the Atterberg’s Limit of the soil as the percentage of Katsi is increased explaining cationic exchange between the Katsi and laterite. And 7.5% Katsi content is recommended as convenient for laterite –Katsi mixture within the content of this study. This is because at 7.5% Katsi content the LL remained the same and the PI was at peak, implying that the greater the dry strength and toughness at plastic limit; the permeability, the rate of volume change and compressibility will remain the same.

Efficient Brain Tumor Detection Using Image Processing Techniques[ ]


The paper covers designing of an algorithm that describes the efficient framework for the extraction of brain tumor from the MR images. The first phase of the Algorithm is Gaussian and Median Filters implemented to enhance the image quality. A couple of morphological operations are applied to calculate the morphological gradient. The filtered image and the morphological gradient image are added to enhance the intensity of the image to make it suitable for further operations. After the enhancement process, the threshold value is calculated using the mean and standard deviation of the image. This threshold value is used to binarize the image followed by the morphological operations. After this tumor area is made visible while rest of the image is darkened to differentiate between the affected and the unaffected area of the brain.

Sustainable Urban Landscape Practices: A New Concept to Reduce Ecological Degradation[ ]


Urbanization is an inevitable process of development of human society and an outcome of economic development and scientific and technological progress. While urbanization process in promoting the development of human civilization, also no doubt, urban landscape has been a corresponding impact. Urban environment has suffered unprecedented damage majorly due to the increase in urban population density and heavy migration rate, traffic congestion and environmental pollution. All this have however led to a major ecological degradation and imbalance. As lands are used for the rapid and unplanned urbanization, the green lands are diminished and severe pollution is created by waste products. Plastic, the most alarming waste at landfill sites, is yet uncontrolled. Therefore, initiatives must be taken to reduce plastic mediated pollution and increase green application. However, increasing green land is not possible due to the landfill by urban structures.
