Abstract:
Approximation of finite population totals in the presence of auxiliary information is considered. Polynomials based on Piecewise polynomial and Newton backward difference polynomial are proposed. Like the local polynomial regression, Horvitz Thompson and ratio estimators, these approximation techniques are based on annual population totals in order to fit in the best approximating polynomial within a given period of time (years) in this study. The proposed Piecewise polynomial technique has shown to be unbiased under a first order polynomial as we approach the target value as opposed to the Newton backward difference polynomial. The use of real data indicated that the Piecewise polynomial is efficient and can approximate properly and give a smooth curve at the knots in the presence of outliers.

Graph theoretical analysis is an important area of research in biological networks. In this work we defined a new graph called Neuropeptide 𝒞 ∗∗ − graph obtained from 𝒞 ∗∗ − set of each protein/peptide graphs of fifteen neuropeptides which involved in the brain function – learning and memory processes. From the graph theoretical analysis we got some observations about the relation among the fifteen neuropeptides. The highest centrality measures of the neuropeptides Beta-endorphin, Galanin, Neuropeptide Y, Oxytocin and Substance P revealed the critical vertices of the graph and they also gave the prominent neuropeptides involved in the learning and memory processes. The neuropeptide 𝒞 ∗∗ − graph showed that all the neuropeptides were connected because every pairs of neuropeptides were inter related by atleast one amino acid which recieved atleast one highest centrality measure and revealed the strength of the relation between neuropeptides with in the brain function – learning and memory processes. This work may help in the study of the mechanisms involved in learning, memory processes and other brain functions and would aid in developing better solutions to treat diseases like Alzheimer’s. Its application may also help in the study of the evolution of neuropeptides involved in learning and memory processes and other brain functions in different species of animals

Abstract:
Alzheimer Disease (AD) is one of the brain related disease that occur due to aging. It affects the brain, degenerate and kills the brain cells therefore causes the shrinkage in the brain tissues. The detection of AD in brain images is very cruicial in present times. In this paper, we proposed a method for detecting the Alzheimer disease in MRI human head scans by segmenting the WM and GM using Spatial Fuzzy Clustering Method (SFCM). This proposed method is a two-tier process, the Tier1 consists of brain portion extraction using skull stripping method and the segmentation of White Matter (WM) and Gray Matter (GM) using SFCM with level set method is processed in Tier2. The WM and GM are further analyzed to detect Alzheimer disease in MR brain images. Moreover, our method is evaluated by the similarity measures such as Jaccard (J) and Dice (D) to assess the efficiency.

Abstract:
Oyster mushroom (Pleurotus spp.) cultivation is a very simple low cost technology. Four Pleurotus spp. viz. P. ostreatus, P. florida, P. pulmonarius and P. flabellatus were grown in 30 ± 2 0C in non-sterilzed rice straw. All the biochemical studies were done using 70% methanolic extract of dried powder of mushroom fruiting bodies. Flavonoids, total phenol, orthodihydric phenol content of all the species were measured in addition to their protein and carbohydrate contents. P. ostreatus showed highest protein and carbohydrate. P. flabellatus showed highest flavonoid. P. florida showed highest phenol content whereas P. florida and P. pulmonarius showed highest orthodihydric phenol contents. Antioxidant activities of the mushroom extract in terms of ABTS and DPPH oxidation and reducing power was estimated in all the species. Though ABTS scavenging activities are more or less similar but DPPH scavenging activities differ markedly in different Pleurotus spp. and P. ostreatus showed the highest result (74+2.2%). The highest reducing power was found in P. florida. The fruiting body as well as mycelial extract of Pleurotus species showed antibacterial activities in as low as 36-45 mg fresh fruiting body equivalent which is comparable to standard commercial antibiotic erythromycin. The present study does not establish the superiority of any single species but in general all the studied Pleurotus species contained different nutraceuticals which may be utilized for the benefit of nutritional as well as health status of people from third world countries

Abstract:
The powerloom industry came to be a successor and extension of the handloom industry. It was therefore obvious that handloom centers in the country developed into powerloom centers also. Of course, there were some other centers which developed independently as powerloom centers for different reasons. The main ailment of the power loom industry is that a large portion of it depends upon the private spinners for the supply of yarn and on the master weavers for the processing of cloth, its sale, etc. The imbalance in the weaving and spinning capacity and lack of a co-operative infrastructure for pre and post weaving facilities have been causing acute economic hardships to the weavers. Besides, as their services are not institutionalized, they have to forgo the commercial gains of their labour and have been reduced to the position of hired labour. The vast majorities of power loom weavers fall in the lowest income group. Majority of them work for master weavers who exploit them by manipulating the prices of raw materials as well as finished goods to their own advantage. Sometimes, weavers are also fleeced by the master weavers and the money lenders, who charge usurious rates of interest on loans taken by the weavers to buy materials or equipments or to tide over difficult periods or for the celebrations of a marriage or the defraying of medical expenses. There is also widespread unemployment among the weavers. This paper is based on secondary data and tries to identify the challenges faced by the workforce in decentralized powerloom sector and the government’s response in resolving these issues

Abstract:
Of late, the quality of education, particularly the higher and technical education in India, has attracted a lot of attention across the country. Failure of higher and technical education institutions in India to meet the global parameters of educational excellence can be testified with the simple fact that our institutions do not figure in the ranking lists of top educational institutions in the world. Along with the quality of education, low employability is the other verity which has raised serious concerns and necessitated the need for course correction in the domain of higher education in general and technical education in particular. Technical Education is one of the most significant components of human resources development in a developing country like India as it creates the required manpower to facilitate the industrial, technical development of the country and consequently the quality of life of the population. In recognition of the importance of this sector, the founding fathers of Indian economic planning accorded utmost priority to this sector. There has been phenomenal growth in the field of technical education during the last seven decades of economic planning in India. At the dawn of independence, there were hardly 4 degree and 8 diploma institutions. There are at present more 3,500 institutions, with intake capacity of around 15 lakhs. This phenomenal growth in the domain of technical education has raised certain crucial concerns for the policy makers and the stake holders. Some of these are ensuring quality of education, promoting the spirit of quest, to working out meaningful curriculum which is aligned with the requirements of job market. The essential rationale of this paper is to look into the challenges before the technical education in India and ways to align it with employability, and creation of a knowledge society which is fitting with the needs of industry and developmental necessities of the country. This paper is divided into three sections – first section sets the background by presenting an overview of engineering education in India since independence, second part enlists the main challenges in engineering education in India, third section makes an attempt to propose certain possible solutions so as to bring engineering education in sync with the imperatives of creating a knowledge society and ensure employability.

Abstract:
In respect of fluid dynamics two phase flow generally refers to a flow in which two material phases are simultaneously present. In some cases, the two phases consists of different physical state of a single material such as bubbles of steam in water (Gas-Liquid). In other cases, the two phases each consists of a different material such as dust particle in air (Solid - gas). Mathematical models of two phase flow are primarily applicable to situation mentioned as above. The two phases in some cases differ from each other with respect to their physical states. However, it is possible to use models to stimulate flows that involve mixture of two immiscible materials that exist in single physical state, for example, droplets of oil in water (liquid-liquid). In the present paper we have studied the MHD flow and heat transfer in both the following two types of fluid mixture :- (a) When the mixture is two fluids. (b) When the mixture is of a gas and dust particles. For the fluid in the two phase of first type, the fluid in the two-phase were assumed to be immiscible, incompressible. It is also assumed that the flow is steady, one-dimensional and fully developed. Further the two fluids are assumed to have different viscosities and thermal conductivities. We have investigated the upper phase and the lower phase of the two fluids was assumed to be electrically conducting and the conductivity of the two fluids is different. The transport properties of the two fluids were taken to be constant and the bounding plates are maintained at consists and equal temperature The analytical solutions for velocities and temperature distributions are obtained and are evaluated numerically for different heights and viscosity ratios for the two fluids and for two values of the electric load parameter R e . The results are plotted graphically. It is observed that in case of open circuit problem for negative values of the electric load parameter R e , the effect of increasing the Hartmann number M is to accelerate the velocity and is to increase the temperature in contrast to the short case. Further it is also observed that with suitable values of the ratios of depths the velocity decreases but the temperature increases. Again if the ratio of the viscosities of the two fluids is increased the velocity increases but the temperature decreases and if the ratio of the thermal conductivities is increased the temperature can also be increased. We have studied the magnetohydrodynamic heat transfer in two phase flow between two parallel plates in presence of a transverse magnetic field. We have assumed that both the phases are incompressible and to have constant transport properties and both the phases are taken to be electrically conducting. The plates were assumed to be maintained at constant and equal temperature. The investigation is expected to the useful in understanding the presence of slag layers on the heat transfer characteristic of coal-fired MHD generator. The boundaries of the generator channel will be assumed to be infinitely long, parallel plates. The exact solutions of velocity and temperature distributions are obtained. The results are shown graphically. Results are also presented for various depths, viscosities and thermalconductivities ratios for the two fluids and for two values of the electric field loading parameters. For the second type, the effect of radiative heat transfer term on propagation of characteristic waves in two phase mixture of a gas and dust particle. When particle volume fraction appears as an additional variable is investigated and with the help of Laplace Transformation analytic solutions are obtained in characteristic plane.

Background: Maternal smoking and alcohol exposure in pregnancy lowers BMI and affects the child IQ. Method: A cross sectional study in which we explored the IQ of school going children in the age group (11-17) and analyzes the factors associated with prenatal exposure of father and mother with the help of designed questionnaire and develop Ordinal logistic regression model.. Intelligence Quotient Score by Dr. P. Shrinivasan verbal intelligence test collected in pre-designed questionnaire in the class room without the presence of school administration so that student feel free in the class room to fill the information given in the questionnaire explained by the researcher. Result: In this study we observed that the mother whose education qualification was 12th pass have highest rate of non smoker category 93% and mother whose education qualification was Matric have highest rate of smoking during pregnancy 9.6%. Mother who smokes during pregnancy was found 10.5 % and 4.6% in urban and rural area. And mother who smoke during pregnancy gave birth to a child in preterm category and full term was 10% and 6.8%. We found there is significant association between children IQ and maternal smoking habit during pregnancy p=0.049. This indicates that maternal smoking habit during pregnancy negatively affects the IQ level of children. In an ordinal logistic regression table we found that these variables namely Alcohol intake of father, smoking habit of father, chewing habit of father, mother smoking during pregnancy, alcohol intake of mother, chewing habit of mother, health status of mother and type of delivery were significantly associated thus we conclude that these variables of prenatal exposure affect the IQ level of children. Conclusion: In our study we used chi-square test and ordinal logistic regression to check the association between children IQ and maternal smoking habit, prenatal exposure of father and mother. Smoking during pregnancy is likely to be one of the factors that affect the IQ of children. We conclude that there is significant association between children IQ and maternal smoking habit by using chi square test and when we apply ordinal logistic regression, we conclude that the IQ of children is affected by the prenatal exposure of father and mother.

Abstract:
Nowadays the Adaptive Noise Cancellation is one of the major techniques of estimating signals corrupted by noise or interference. The main advantage is no acceptable estimates of signal or noise, levels of noise rejection getable that may be troublesome or not possible to attain by different signal process strategies of removing noise. Its cost, inevitably, is that it wants two input signal such as original signal and noisy signal. The reference input is adaptively filtered and ablated from the first input to get the signal estimate. Reconciling filtering before subtraction permits the treatment of inputs that settled or random, stationary or time-variable. The result of unrelated noises in primary and reference inputs, and presence of signal parts within the reference input on the ANC performance is investigated. it's shown that within the absence of unrelated noises and once the reference is freed from signal, noise within the primary input may be basically eliminated while not signal distortion. A configuration of the reconciling noise canceller that doesn't need a reference input and is extremely helpful several applications is additionally use of ANC while not a reference input for canceling periodic interference, reconciling self-tuning filter, antenna aspect lobe interference canceling, cancellation of noise in EEG signals, etc

Abstract:
Evaluate the performance of database systems are more difficult with the existence of different database management systems such as MS SQL Server, Oracle, My SQL and so on, which serves different requirements. As DBMSes are limited in speed with respect to time, they need to be highly efficient and effective through their performances that demand by the market. A DBMS provides different facilities for controlling data access, data summarizing, enforcing data integrity, managing concurrency control, transaction system, recovering the database after failures and restoring it from backup files, as well as maintaining database security. It is a set of software programs that controls the system organization, storage, management, and retrieval of data in a database. That is why they need to be efficient in storage and speed. This is the same reason why DBMSes need to be evaluated based on their performances. Different DBMSs performs differently in different environment. This paper, evaluate the performance of Three different database management systems(MySql, Sqlite, PostgreSQL). Based on that, comparison of different DBMSs in the same environment is possible. This performance evaluation is done based on responce time and memory capacity.

Abstract:
This paper presents an optimization technique to dynamically balance the planar five-bar mechanisms in which the shaking force and shaking moment are minimized using the genetic algorithm (GA). A dynamically equivalent system of point-masses that represents each rigid link of a mechanism is developed to represent link’s inertial properties. The shaking force and shaking moment are then expressed in terms of the point-mass parameters which are taken as the design variables. These design variables are brought into the optimization scheme to reduce the shaking force and shaking moment. This formulates the objective function which optimizes the mass distribution of each link. The balancing problem is formulated as a multi-objective optimization problem and multiple optimal solutions are created as a Pareto front by using the genetic algorithm. The masses and inertias of the optimized links are computed from the optimized design variables. The effectiveness of the proposed methodology is shown by applying it to a problem of five-bar planar mechanism available in the literature.

Abstract:
Liquefied petroleum gas (LPG) is among the most common and ubiquitous of the fossil fuelsemployed by us. In contrast to other fossil fuels commonly used by everyone in day-to-day living ─ petrol, diesel, and kerosene ─ which all are a highly flammable, hence hazardous, LPG does not only carry flammability hazard but also the risk of explosion. Due to the very extensive and continuous use of LPG, the risk of LPG−related accident is ever present. This paper deals with the risk associated with the storage of LPG in large installations and reviews the safety codes prescribed by different agencies across the world to minimize the risk. It then p

Abstract:
The properties of H13 are dependent on the microstructure, the composition, and the heat treatment. The microstructure of H13 steel is composed of a tempered Ti C matrix, with various alloying element carbide precipitates distributed within. These carbides are composed of molybdenum, vanadium, chromium and iron. The size of the carbides varies for each alloying element that composes it. The molybdenum and vanadium carbides tend to be larger in size and clustered together. Carbides, composed of iron and chromium, are distributed evenly and therefore are very fine and do not form clustered colonies. The size of the carbides plays a key role in fracture. The present work discuss the life feasibility of the die by practical way of observing micro structures of bottom die after crack propagation and the hardness levels of heating. The process has been carried out on 1 ton hammer for observation of load impacts on the die

Abstract:
During chemical based enhanced oil recovery (EOR) process, ultralow oil-water interfacial tension (IFT) (less than 10-2 mN/m) should be achieved to mobilize the residual oil left behind after conventional recovery methods. This research work studied the phase behaviour of surfactant systems with a view to screen formulations for chemically enhanced waterflooding with ultralow IFT. The phase behaviour tests help to determine the optimum salinity, which is one of the most important parameter in the surfactant flooding because it is at this salinity at which maximum oil recovery can be obtained. The phase behaviour studies of (surfactant + brine + crude oil) systems were performed with various combinations of chemicals with crude oil (31 0API) of an Upper Assam oilfield at reservoir temperature (70 0C). The surfactants considered for the experimental works were Sodium Dodecyl Sulphate (SDS, anionic), TritonX-100 (TX-100, non-ionic) and Black Liquor (BL, natural). Five core flood experiments were done to determine the EOR potential of the surfactants used and to validate the chemical formulations that performed well in phase behavior experiments. Mixed surfactant systems were found to perform better in the phase behavior tests and recovered higher residual oil during core flooding due to synergistic effect.

Abstract:
The real-time Web can provide timely information on important events, and mining it online with stream processing allows yielding maximum benefit from it. In this chapter we proposed an application to online news recommendation. Our goal is to help the user keep up with the torrent of news by providing personalized and timely suggestions. We described T.REX, an online recommender that combines stream and graph mining to harness the information available on Twitter. T.REX creates personalized entity-based user models from the information in the tweet streams coming from the user and his social circle, and further tracks entity popularity in Twitter and news streams. T.REX constantly updates the models in order to continuously provide fresh suggestions.We framed our problem as a click-prediction task and we tested our system on real-world data from Twitter and Yahoo! news. We combined the signals from the two streams by using a learning-to-rank approach with training data extracted from Yahoo! toolbar logs. T.REX is able to predict with good accuracy the news articles clicked by the users and rank them higher on average. Our results show that the real-time Web is a useful resource to build powerful predictors of user interest.

Abstract:
Large-scale blast testing has proved that full-field displacement and in-plane strain data can be reliably obtained for composite sandwich panels secured around their edge during explosive events. Detailed deformation maps were obtained using digital image correlation (DIC) under extreme shock loading conditions and have been validated by point measurements using a laser gauge system. The DIC technique is now being adopted by other research groups for similar blast experiments. Important in this researchwas the support arrangement for the composite sandwich panels and how it influenced, as a design consideration, the mode and location of failure. Several studies were conducted which showed a number of real scenarios for naval structures, such as multiple blast impacts as well as a number of different blast impacts on a number of different constructions. Each of these studies has shown that the modes of failure are front-face dominated compared to the underwater blasts, which involved both front- and back-face failures being observed.

Abstract:
The kinetics of the alkali catalysed hydrolysis of Ethyl Iso-valerate (Aliphatic isovalerater) was studied in aquo-aprotic solvent systems(aquo- DMSO) and the specific rate constants of the reaction were found decreasing with increasing concentration of the organic content (DMSO) of the media. It is inferred that dielectic effect and the solvation changes are the causes of depletion in the rate of the reaction.

Abstract:
For highlighting the solvent effect of a dipolar protic solvent secondary alcohol on the rate, thermodynamic activation parameters and solvent-solute interaction of a solvolysis reaction, the kinetics of acid catalysed hydrolysis of Iso-propyl formate was studied in aquo-propan-2-ol media of varying composition containing 20 to 80% propan-2-ol at five different temperatures i.e. 20, 25, 30, 35 and 40oC. The changes observed in the values of iso-composition and isodielectric activation energies of the reaction have also been explained in the light of solvation and desolvation of initial and transition states to different extent. From the evaluated value of iso-kinetic temperature which comes to be 328.0, it is inferred that there is strong solvent-solute interaction in aquo- propan-2-ol media. Effects of ionic strength and change in [H+] ion concentration on the rate of reaction have also been studied and it is concluded that the acid catalysed hydrolysis of Iso-propyl formate is ion-dipolar reaction and it follows AAC 2 mechanistic pathways in aquo- propan-2-ol reaction media.

Abstract:
There has been expanding worry for Golden Eagle (Aquila chrysaetos) populaces in North America because of current and future projections of mortality hazard and natural surroundings misfortune from anthropogenic sources. Recognizable proof of high-use development halls and bottlenecks for the transitory part of the falcon populace in western North America is a significant initial step to help territory protection and the executives endeavors to lessen the gamble of bird mortality. We utilized unique Brownian Bridge development models to assess usage disseminations of grown-up falcons moving across the western North America and distinguished high-use regions by computing the cross-over of people on populace and provincial levels. On a populace level, the Rocky Mountain Front from east-focal British Columbia to focal Montana and southwestern Yukon enveloped the most involved relocation hallways with our review degree for both spring and fall. Local examination on a 100 x 200 km scale uncovered extra moderate and significant level use halls in the focal British Columbia levels. Birds were more scattered in the spring until their courses joined in southern Alberta. High-use fall halls broadened farther south into focal Wyoming. Information on these high-use regions can support preservation and site wanting to help keep up with and improve transitory Golden Eagle populaces in western North America.
