Methodology Oriented Thermoelectric Transport Properties of CaMn0.98Nb0.02O3[ ]


Perovskite n-type CaMn0.98Nb0.02O3 compound is synthesized by three different synthesis methodology: solid-state, sol-gel and combustion synthesis. Phase purity and microstructure of the synthesized samples are investigated by using powder X-ray diffraction and scanning electron microscopy, respectively. The electrical resistivity values of all the samples of CaMn0.98Nb0.02O3, synthesized by three different methodology, decrease with increasing temperature as expected from the presence of Mn3+ ions with eg electron in the Mn4+ matrix of CaMnO3. The transport properties are explained by Mott’s small polaron hopping mechanism. In the high temperature range, CaMn0.98Nb0.02O3 phase synthesized by combustion synthesis exhibits large Seebeck co-efficient (S975K = -162 μVK-1) and low electrical resistivity (ρ975K = 16 mΩ.cm) values, results in a high power factor of 143 μWm-1K-2 at 975 K. The above phenomena can be interpreted as variation in porosity of CaMn0.98Nb0.02O3 arising from the different synthesis route where combustion method results in lowest porosity among the other methodologies.

DESIGN AND DEVELOPMENT OF A LOW COST FLOATING SOLAR POWER PLANT[ ]


The constant rise in green and sustainable energy demand has been shifting the global focus to develop technologies to utilize the renewable energy sources to the maximum extent possible. Solar energy, owing to its availability across the globe in abundance along with its pollution free nature, is considered to be the best renewable energy source. One of the major challenges posed by solar energy systems is the requirement of large area of land to mount the PV panels. As the availability of land is becoming scarce and the cost of it is increasing day by day, technological solutions to utilize water bodies to mount PV panels are being explored. The PV panels when floating on water, are expected to stay cool and hence would generate more power than those setup on land.The floating solar panels help preserve water levels by reducing evaporation during extreme summers, they also limit the growth of algae and in turn improve the acquatic life sustainability. This work is aimed to design, develop and demonstrate a low cost floating solar power generation module, which can be utilized, in multiple ways, to boost the rural economy.

Dry wear characteristics of nickel rich Al-Si-Cu piston alloys[ ]


Wear and friction characteristics of Al-Si-Cu-Ni piston alloys have significant importance in the field of automobile industry by considering the environmental and economic factors. The present study aims to investigate the effect of varying Ni weight percentage from 2 wt. % to 2.6 wt. % on the microstructural, physical and mechanical characteristics of the Al-12.6Si-3Cu-(2-2.6 wt. %) Ni piston alloys. Wear and friction characteristics of the Al-12.6Si-3Cu-(2-2.6 wt. %) Ni piston alloys were investigated at different sliding velocities (0.2-1 m/s) by using pin-on-disc tribometer under constant normal load of 30 N and sliding distance 500m. The microstructural observations showed that the needle like β eutectic silicon’s are fragmented, spheroidized and evenly dispersed in the α-Al matrix after heat treatment under T6 conditions. It has been observed that the maximum hardness of 136 BHN obtained for Al-12.6Si-3Cu-2.3Ni Piston alloy. The maximum ultimate tensile strength of 230 MPa obtained for Al-12.6Si-3Cu-2.3Ni Piston alloy among the Al-12.6Si-3Cu-(2-2.6 wt. %) Ni piston alloys. Wear loss of Al-12.6Si-3Cu-(2-2.6 wt. %) Ni piston alloys decreases with the addition of 2.3 wt. % of Ni. A transition in the wear loss observed at a critical velocity of 0.6 m/s for the Al-12.6Si-3Cu-(2-2.6 wt. %) Ni Piston alloys. However considerable decrease in the wear loss occurred by the addition of 2.3 wt. % of Ni and the minimum wear loss observed in the case of Al-12.6Si-3Cu-2.3Ni piston alloy in all the sliding conditions such as constant normal load 30N, constant sliding distance 500 m and sliding velocities in the range of 0.2-1 m/s.

Optimal Mother Wavelet Function for EEG Signal Analyze Based on Packet Wavelet Transform[ ]


Electroencephalogram EEG signal is usually contaminated by different noise sources, which are called as artifacts. These artifacts need to remove before processing and analyzing the EEG signal. Several noise removal techniques are available and implemented. This paper presents a detail analysis of EEG de-noising using Packet Wavelet Transform (PWT). We carried out comparative study to choose the optimal mother wavelet basis function. The EEG database is freely acquired from MIT-BIH arrhythmia database for five control subjects. The EEG signal is grouped into five regional groups according to scalp regions. These groups are frontal, parietal, occipital, temporal, and central regions. Twenty five mother wavelet functions are researched. The functions are daubechies (db1 – db10), symlets (sym1 – sym10), and coiflets (coif1 – coif 5). These five groups are analyzed on these 25 mother wavelet functions (MWT). The cross correlation coefficients between signal of interest and wavelet de-noised signal are evaluated for the control subjects. The mother wavelets with better cross correlation coefficient can be selected as the optimal MWT basis function. This work is simulated and implemented using wavelet toolbox from MATLAB 2013 software environment.

A reliable Evaluation Method for 2D Wireless Sensor Network Deployment[ ]


In recent years, Wireless Sensor Networks (WSNs) have rapidly evolved and now comprise a powerful tool in monitoring and observation of the natural environment, among other fields. The use of WSNs is critical in early warning systems, which are of high importance today. In fact, WSNs are adopted more and more in various applications, e.g. for fire or deformation detection. The optimum deployment of sensors is a multi-dimensional problem, and has two main components; network and positioning approach. Lots of work has dealt with the issue, and one can find several solutions for sensor deployment either achieving ideal network topology or achieving fine geometry. In most cases, it is hard or even impossible to achieve perfect geometry in nodes’ deployment. The desirable scenario of nodes arranged in square or triangular grid would raise extremely the cost of the network, especially in unfriendly or hostile environments. However the user wants to know how much does the deployment plan, approximates the ideal geometry. A geometry as near as possible to the ideal one, minimizes the numbers of sensors needed, which subsequently means less costs for the entire network. This paper suggests an evaluation method for 2D Wireless Sensor Networks, concerning the geometry of the distributed sensors, in large scale WSNs. It approximates the solution comparing the random TIN that the nodes of the network form, with the ideal geometry, i.e. the regular equilateral triangle grid. The user knows a priori, how much does the proposed deployment plan, achieves a deployment as near as possible to the ideal one, for the given characteristics of the study area.

RICE SELF-SUFFICIENCY: A REVIEW OF GOVERNMENT POLICIES ON RICE PRODUCTION[ ]


The need to make Nigeria self-sufficient in rice production necessitated the introduction of improved ways of producing, processing and storage through various government inter interventions to enhance domestic rice production in the country. Attaining self-sufficiency in rice production involves strong policy formulation and implementation aimed at infusing improved seeds, machines and techniques into rice farming. Several policies had been introducedin the past but failed to achieve the desired target of increasing local production to a level of self-sufficiency and exportation. Policy gap from successive administrations, corruption and insincerity on part of driving agencies also contributed to this debacle. This study was therefore carried out to review the policies, constraints and recommend viable solutions to achieving this goal.

Perceived image quality prediction based on image quality attributes extraction[ ]


As the smartphones and tablet computers with embedded cameras and high definition resolution became an essential part in our life. A great deal of effort has been made by the smartphones vendors in recent years to develop an “objective” image quality metrics in order to predict the how the image quality is perceived by the consumers. Unfortunately, only limited success has been achieved. This paper describes the evaluation of a new “objective” image quality model that predicts the perceived image quality. The new model is based on the standard image quality attribute extraction to the VQEG image quality evaluation tool criteria. This improves and reduces the process and cost by providing a new quantitative method to evaluate perceived image quality of color images on smartphone displays. Four image quality factors: brightness, contrast, color saturation and sharpness, were chosen to represent perceived image quality. This new image quality assessment model is based on results of human visual tests that compared with image analysis by the software application VIQET. During the research, the VIQET tool was calibrated based on results from human visual experiments. This paper describes the evaluation of the new model according to the VQEG recommendations.

The Impact of Decentralization of the Philippines’ Public Health System on Health Outcomes[ ]


In 1991, the Local Government Code of 1991 was constituted to commence, among others, the decentralization of the republic's health care structure from the national administration to local government units (LGUs). This was recognized on the concept that with decentralization, health system in the country would be strengthened. As the directive continued, past researchers concluded a system failure in the country’s health sector upon its implementation. To scrutinize the previous scholars’ suppositions, this study assessed the impact of the decentralization of the Philippines’ public health system on health state of the population. The researchers pursued such analysis by utilizing the econometric model based on the Andrei, T., Mitrut, C., Constantin, D.L., & Oancea, B. (2009) study who dedicated their inquiry on the impact of decentralization of Romania’s public health system to Romania’s populations’ health state, and by using 1980-2012 data series measured by national-level statistics. The researchers found out that total government health expenditure, and bed capacity per 10,000 populations are statistically significant and has a progressive influence to the population health conditions with a decline in infant mortality rate by 1,000 live births. However, the government doctors’ population relative to infant death ratio was uncovered to be statistically insignificant.

Data Treatment, Childlessness and Singleness for Better Policy Proposition in Entrepreneurial Literature[ ]


This short note gathers from a literature survey evidence of the inefficiency of entrepreneurial findings in leveraging policy orientation and implementation on large group of people to boost supply in entrepreneurship, especially from unemployed youths. Meanwhile, governments, international organizations and various stakeholders are spending huge funds to prepare the environment or rather, to make it conducive for entrepreneurial development. An accusing finger points at research design and data analysis directed toward theoretical formulation and testing. The author offers data analysis treatments that are policy oriented and proposes gaps which findings could be of great help to policy makers. More precisely, composite index and latent class analysis are presented as better methods leading to policy orientation. These methods conveniently handle the multi-dimensional measure of personality traits, entrepreneurial development and entrepreneurship conceptual framework. Furthermore, the role of singleness and childlessness in inhibiting or promoting entrepreneurial development for economic and social inclusion is not quite clear; though it is well known that they are inherent attribute that foster social exclusion.

A Comparative Analysis on the Physical Property of Different Types of Yarn and Their Relation with Knitting Productivity and Knitted Fabric Quality[ ]


At the very beginning of this research work we have done a comparative study among the property of card yarn, combed yarn, mechanical compact yarn and pneumatic compact yarn. To make a fair comparison, all the yarns are produced with same linear density, same raw material and nearly about same TPI. Among all the yarns pneumatic compact yarn shows superior quality in terms of evenness, hairiness, strength etc. Then all types of yarn are knitted to make fabric by keeping same knitting parameters and same fabric construction. Then the knitting production per day is calculated. Investigation shows that pneumatic compact yarn gives higher production per day and it has the higher quality among all type of yarns and production per day decreases with the decreasing in yarn quality. Finally, we have investigated the bursting strength, weight loss due to abrasion and pilling resistance of the four fabrics. Test results show that all these properties are completely depends on the quality of yarn. Pneumatic compact yarn exhibits higher bursting strength, abrasion resistance and pilling resistance property and consecutively decreases for mechanical compact, combed yarn and card yarn.

User Location Time and Entropy (ULTE) based Salt generation for Password Based Key Derivation Function (PBKDF) in Cloud Computing[ ]


Virtualization is the biggest issue in our modern life with information technology. For accessing data globally and timely people are storing data, information, and programs into Cloud Storage Space. Cloud service providers (CSPs) maintain authentication and authorization mechanism but there are no mechanisms for data security. If the users’ credentials are compromised then information could be misused, or stolen. Client Side Encryption Tool (CSET) is used widely with their own features and security schemes to overcome the security problems in CSPs. CSET encrypts each data file of client’s with encryption key which are derived by a specialized algorithm called Password Based Key Derivation Function (PBKDF), and Salt, a random value plays vital role for making each encryption key unique and different from other keys. Through analysis, we found that: generation of Salt by using any Pseudo random number generation algorithms could lead the intruders like hackers to crack the encryption keys for multiple files stored in CSPs. Therefore, a new random number generate algorithm (ULTE) for Salt generation which is based on users’ Location Information, Time Information, and Entropy Data (bit strings of system noise sources like thermal noise or HDD seek time) is proposed. Simulation result shows the whole processes of Salt generation according to the ULTE Salt Generation Algorithm.

Progressive Collapse Analysis of Multi-Story Space Frames[ ]


The progressive collapse of building structures is initiated when one or more vertical load carrying members (typically columns) is re-moved. Once a column is removed due to a vehicle impact, fire, earthquake, or other man-made or natural hazards, the building’s weight (gravity load) transfers to neighboring elements in the structure. If these elements are not properly designed to resist and redistribute the additional gravity load the vertical load carrying elements of the structure continue to fail until the additional loading is stabilized causing greater damage to the structure than the initial cause.

IMPROVEMENT OF WEAR RESISTANCE QUALITY IN ALUMINIUM METAL MATRIX COMPOSITE – A REVIEW[ ]


Aluminum composites are the most generally utilized nonferrous materials in designing applications attributable to their appealing properties, for example, high quality to weight proportion, great flexibility, magnificent erosion resistance, accessibility and minimal effort. In any case, their applications have regularly been limited on the grounds that traditional aluminum amalgams are delicate and famous for their poor wear resistance. This issue was overcome by fortifying unmistakable particulates in aluminum and its mixes to make a sustained metal framework composite which has about isotropic properties. After fortress, Aluminum Metal Matrix Composites (MMCs) have enhanced properties, for instance, adaptable modulus, hardness, versatility at room and raised temperatures and enormous weight finances over unreinforced mixes. Inferable from their extraordinary upgraded properties, Aluminum Metal Matrix Composites (MMCs) are searched for over other customary materials in the field of aerospace, auto and marine applications. This paper uncovers the broad work that has been accounted for to enhance wear properties of Aluminum based Metal Matrix Composites.
