Agent orientated techniques will create a considerable involvement to the execution of statistics/information system via supplying extra capability and improved person interface. In this thesis, we tend to specialize on the usage of A.O context inside the primary degrees of the model of a system especially in R.E. Agent principles had been brought in R.E mostly as molding paradigms to represent energetic factors within the surroundings, normally consisting of the target system, The crucial degree of achievement of a software system is the grade to which it encounters the reason for which it turned into supposed. R.E is the technique of coming across that reason. R.E is a division of S.E whose vital aim is to supply a few systematic performances to its investors. There is a growing consideration because of its non concrete and imperceptible nature of s/w and the size-able variety and type of troubles that disclose to s/w solution. A.O designs are getting very famous in S.E as demonstrating contexts for R.E.
A high momentum jet tangentially flowing over the surface of a rigid flat plate is a wall jet. Understanding the flow physics of wall jets can be helpful in several practical applications, such as cooling off turbine blades, mixing off reactants in a combustion, air curtains, etc. Moreover, the rich flow physics in wall jets has inspired numerous researchers to work in this field. Wall jets are widely investigated to understand the flow turbulence, entrainment, mixing behavior, and formation of coherent structures. Presently, the study on acoustics emission from wall jets is also gaining significant importance. The schematic of a wall jet. As observed from the figure, the wall jet has two flow layers: the inner and outer layers. The former layer is due to the interaction between the jet and the solid surface of a plate, and the outer layer is due to the interaction between the jet and the ambient fluid. The inner layer initiates from the wall surface and extends up to the location of maximum stream-wise velocity, thus resembling a boundary layer. The outer layer region is between the maximum stream-wise velocity and the ambient flow velocity, thus representing a free shear layer.
With the current sedentary lifestyle, aging population, trauma, injury and diseases, the worldwide occurrence of bone related disorders is expected to increase two-folds by 2020. Hence, the demand for bone grafts have gone up exponentially. Autologous bone grafts have been the gold standard for bone regeneration since ages. The present demand for autologous bone grafts has exceeded the availability, hence making grafts the second highest priority. But the grafts come with a lot of disadvantages like slower/poorer healing, immunological response and reduced Osteo-conduction and Osteo-induction. These issues gave rise to the field of Bone Tissue EngineerinG which is an amalgamation of science, engineering, and medicine. The key aspects of BTE are as follows, biocompatible material for scaffold fabrication, scaffold mimicking the hierarchy of the bone tissue, osteogenic cells, and physical/mechanical/chemical supplements for cell growth and proliferation on the scaffold. Current generation tissue engineering aims at designing implants which induce tissue formation at the site of injury. To achieve this, various events are necessary such as: responsive host cells, a suitable scaffold to hold the growing cells, morphogenetic signals which guide the various aspects of cell development, followed by a nicely vascularized host bed to supply nutrients to the growing tissue. This led to the development of synthetic bone substitutes (made from polymers or ceramics) which have replaced the traditionally used grafts. Conventionally, an ideal scaffold is said to be the one which provides a suitable environment for cell adhesion, proliferation, migration and growth. Additionally, it should provide the proper micro-environmental conditions for differentiation of mesenchymal stem cells, into the required cell types and assist in the production of required extracellular matrix. The synthetic substitutes have evolved over a period to match the properties and functionalities of natural bone grafts. However, they are still far from meeting the clinical requirements.
Considering the economical and environmental aspects that have gained importance recently, the strengthening of the new and existing concrete structures has become an important upcoming alternative rather than demolishing and reconstructing. The deterioration and aging of concrete structures are not the only reason for strengthening; it can also be a faulty design or execution, upgrading design standards, increase in the load carrying capacity, accidents such as earthquakes and corrosion of reinforcements. The strengthening of structures implies repair and rehabilitation of the damaged existing concrete members, or retrofitting of a new structure or structure under service to improve its structural properties such as, strength, stiffness and so on. The traditional retrofit methods followed are concrete confinement and steel plate bonding to increase the load carrying capacity.
The inability of cartilage tissue to self heal due to the avascular nature often leads to conditions such as osteoarthritis, traumatic rupture of cartilage and Osteochondrosis. the cartilage provides cushioning effects between joints and avoid bone frictions, the extra cellular matrix of cartilage consists predominantly of collagens, elastin, proteoglycans and glycoproteins. reconstruction of cartilage is difficult and one of the most discussed issues for researchers and clinicians of lately. until today adequate supply of cartilage replacement metrics and scaffolds with similar microenvironment of native cartilage still remain restricted. currently, numerous experiments are going on xenogeneic scaffolds and bio implants from from extracellular matrices worldwide. the decellularized tissues provide appropriate bioactive cues in the absence of cellular components, hence avoiding immunological issues.
Fishes are the first vertebrates with jaws, which are cold-blooded animals and can breathe through gills, there are about 36,000 species, which represent 40% of the total vertebrates present on the planet earth. They have evolved during Ordovician period and widely distributed during Devonian period, which is known as ¿Golden age of fishes¿. The study of fishes is known as Ichthyology. They live in all types of water bodies and have a great significance in the life of mankind, being an important natural source of protein and omega 3 fatty acids, providing certain other useful products as well as economic sustenance to many nations (Piska and Naik, 1999). The capturing and culturing of the aquatic organisms in salt water accounts for bulk of the fishery products that reaches world markets. World capture fisheries production and aquaculture peaked about 140 metric tonnes in 2002 (FAO, 2002). In most countries, marine fisheries employ many of the fishers (Abu Talib et al., 2003a; Boonchuwongse and Dechboon, 2003; Cruz Trinidad, 2003; Long, 2003). The marine sector dominates capture fisheries production in all countries, [60-85%] and these tend to be dominated by demersal species (Janetkitkosol et al., 2003; Abu Talib et al., 2003b). Srilanka and the Philippines are exception where pelagic species dominated the landings from coastal fisheries (Barut et al., 2003).
Cartilage and bone are specialized connective tissues that primarily function as support structures for other adjacent tissues and organs. Both tissues can be characterized by the presence of an abundant extracellular matrix mainly dominated by collagen.Cartilage tissue is found throughout the human body in various types. Three main types of cartilage are elastic cartilage, hyaline cartilage and fibrous cartilage. This study focuses on load-bearing meniscus tissue, a type of fibrous cartilage found in human knee,. It consists of two components, the medial and the lateral meniscus.The current medical scenario necessitates the development of treatment alternatives for meniscus and bone injuries. As we observe that these defects vary in dimension from patient to patient, a customized treatment is ideal for better tissue repair. Tissue engineering alternatives are being extensively explored for the purpose of tissue and organ reconstruction as these overcome the limitations of autologous implants and possess the potential for enhancement of tissue regeneration and repair.
The growing scarcity of power resources tends researchers to find alternate sources to generate electric power. Even though the electric power could be generated from various natural resources, the only all time available resource throughout the year is sun light. The power generation from sun light is called up with the name photovoltaic system, which consists of varying number of photovoltaic cells that stores generated electric power for some time. Generally the deviation between the generated unit of electricity and consumed unit of electricity is higher due to the conduction loss. Similarly there is a conversion loss which is called switching loss present in every electric system. The energy generated from photovoltaic system has to be regulated to provide uninterrupted power supply according to the system to which it has been connected. There are many devices necessary for the conversion and regulation of power supply to the output device. In this research Cuk converter is considered which is a popular and efficient converter being used in the electronic world.
A converter with a single input and multiple outputs is known as a multi-output converter. The converter could be isolated or non-isolated. A non-isolated converter which uses a single common inductor for all the outputs is termed single-inductor multi-output converter. In a multi-output converter, a part of the converter circuit is common for all the outputs and a part of the circuit is exclusive to each output. This brings in cost advantages and improved power density. Fewer components also result in reduced losses. Multi-output converters have become very popular recently and many low power and portable applications widely use such converters. Since a part of the converter is common for all the outputs, achange in the load of one output affects the other outputs also. This is known as cross-regulation and the converters have to handle this apart from line and load regulation. This is what makes the topic complex and interesting and provides scope for further investigation, despite the large volume of research work already existing in this area. This thesis attempts to identify new topologies and control approaches for configuring such multi-output converters in all spheres, isolated or non-isolated, converters operating in discontinuous conduction mode or in continuous conduction mode and with uni-polar or bi-polar outputs.
A number of digital applications e.g. professional cameras, voice communication, video digitizers, data imaging and many more require low power, high speed, and high resolution analog to digital converters. But for high speed data communication systems with increased resolution and high sampling rates, different linear and nonlinear errors of ADCs come in picture which is a big challenge for design engineers to remove.A unique digital background calibration technique, a combination of signal dependent dithering with butterfly shuffler is proposed here for multi-bit, SHA-less 16-bit, 125 MS/s Pipelined ADC. The purpose of the research work was to integrate different stages of different sizes to achieve 16-bit error-free output at high sampling rate by using unique background calibration technique for SHA-less circuit. Because the achieved values of SNDR and SFDR are high with low power consumption, so this proposed ADC is suitable for high resolution applications like video communication. Without using sample and hold amplifier we saved power and reduced noise interference. Additional advantage of SHA removal is to use a smaller input sampling capacitor which increases ADC's drivability. A new timing diagram is also proposed here to resolve the sampling clock skew. The ultimate multi-bit front-end proposed here helped to save further power.The proposed comparator is able to avoid the kickback as compared to traditional comparators. For the initial multi-bit stage, a two-stage gain boosted amplifier is used to achieve high gain and to reduce the nonlinear gain errors. Because the non-idealities of Op-amp and capacitor mismatching errors, the ADC transfer function may achieve erroneous values by DNL errors, so the proposed technique is made capable to remove linear gain and offset errors and capacitor mismatching errors. Also the small signal linearity errors removed with the proposed architecture of 16-bit Pipelined ADC. Along with these advantages, high values of SNDR and SFDR has achieved, which is a top most indicator to distinguish the signal out from other noise and spurious frequencies.

A large number of various therapeutic devices are available in the market with the best efforts of bio-medical engineering.
Bank as is understood in general terms is a depositor or lender for the safekeeping of money. With the changing times banks are performing a host of other financial services like insurance, mutual funds, securities, etc. It is important to look at some definitions of banks to understand the concept of bank."An institution that provides a great variety of financial services. At their most basic, banks hold money on behalf of customers, which is payable on demand, either by appearing at the bank for a withdrawal or by writing a check to a third party. Banks use the money they hold to finance loans, which they make to businesses and individuals to pay for operations, mortgages, education expenses, and any number of things. Many banks also perform other services for a fee; for instance they offer certified checks to customers guaranteeing payment to third parties. In some countries they may provide investment and insurance services. With the exception of Zero Interest based banks, they pay interest on deposits and receive interest on their loans. Banks are regulated by the laws and central banks of their home countries; normally they must receive a charter to engage in business. Banks are usually organized as corporations.Commercial banks are mainly concerned with managing withdrawals and deposits as well as supplying short-term loans to individuals and small businesses. Consumers primarily use these banks for basic checking and savings accounts, certificates of deposit and sometimes for home mortgages.
With the increased rate of socio-economic activities due to fast-growing population and urbanization, disasters especially earthquakes, even today lead to large-scale destruction and loss of life. Urbanisation and rapid development of cities depend upon their location in regard to ecology, geology, demographic structure, economic opportunities and land use pattern. Thus, with people moving towards urban centers, the scale of risk and vulnerability is ever increasing. In developing countries like India, the socio-economic setup of cities becomes imbalanced mainly due to unauthorised construction taking place, lack in the enforcement of guidelines and forcing the poor to live in the most vulnerable areas within it.
The easy access to all kinds of media and information have made them much smarter than their previous generations. The major influence out of all the media on children is that of cartoon characters which are available on all kinds of media like television, internet, YouTube videos, games etc. Out of all the media, the most impactful is the television which has become a necessity in every household now. Cartoons are available 24 X 7 on satellite television through a number of channels dedicated only to cartoon shows. Cartoons have become immensely popular among children due to their attractive color schemes, speeding light flashes and rapid movements which immediately capture the child's attention.
One of the major sectors which have seen a rapid growth in the last decade is mobile telecommunications. It has not only become an important part in peoples lives but also playing a part in world business as the entire world is connected by telecommunication networks. The growing power demand and the dwindling fossil fuels resulted in the unreliable power supply, which is the critical challenge facing by telecommunication industries. Currently, telecom towers are using Diesel Generators (DG) as source of supply, which is rather expensive and emits environmental pollutants. This study analyses the solar photovoltaic (PV) system and battery based hybrid power supply system to reduce the usage of DG. The effective utilization and management of the PV and Battery sources increases the efficiency and reliability of the system. Therefore, in this work, a literature review related to maximum power point tracking of PV array, Li-Ion battery aging mechanism and battery state of health (SoH) estimation techniques have been presented.
"Health is wealth", one who has good health can enjoy the pleasures of life. Healthy people make a healthy nation. Good health is essential for human welfare and sustained economic and social welfare. Traditionally good health is viewed merely as the absence of disease. Generally one who has strong built and muscular body is considered to be healthy. World Health Organization (WHO1946) definition of health is "Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity"
Bahrain is one of the pioneers of modern Islamic banking, with origins tracing back to 1970s. Presently, the kingdom has become the international hub of shari'a-compliant financial services, playing host to the largest concentration of Islamic financial institutions in the West Asia. Economically, Bahrain is a nation in transition with some unique economic features. It has a diversified economy and the dependence of the Kingdom on the oil resources is comparatively less than the other members of the Gulf Cooperation Council (GCC).
Wireless Sensor Nodes of a network have some major constraints due to their limited energy, storage capacity, computing power and frequent battery replacement factor, when they meant to collect the information from an unattended location using various sensors. The modern wireless sensor networks deals with power consumption by the sensor node, communication defects, mobility of nodes, size of the sensor node and importantly cost of the sensor node. The power consumption of a sensor node as it is the main criteria in all wireless sensor networks (WSNs). Hence this proposed research implements a novelty power management system by introducing pack of two solar powered batteries and an automatic battery switching system with Lab VIEW based real time data acquisition. By implementing an Automatic Battery Switching System, a long life sensor node is designed and Lab VIEW based real time data acquisition is achieved.
Land subsidence is a natural hazard that causes gradual settling or sudden sinking of the Earth's surface due to the subsurface movement of earth materials. It is essentially a vertical downward movement of the land surface with little or no horizontal movement and results in loss of surface elevation compared to the surrounding areas. Every year, the phenomenon influences many areas globally causing huge economic, social and environmental losses. It has become a major problem worldwide threatening the viability, sustenance and economic development for millions of people, with total losses amounting to many billions of dollars every year, including the loss of human lives and several menacing environmental damages.

Lean Manufacturing Systems (LMS) have attracted serious attention among practitioners and researchers in recent years. The principles and practices of Lean Manufacturing (LM) were not only implemented in manufacturing organizations, but also in service organizations. Although numerous articles dealing with the theory and practice of LM have been published, ironically, not many organizations have been successful in implementing the LMS and demonstrating a significant improvement in performance similar to that of Toyota Motor Corporation (TMC). Many researchers have pointed out that one of the reasons for the same is that there is an improper understanding among the practitioners regarding LMS. However, implementing change management programs like LMS requires a thorough understanding of the constituents of LMS, performance measures of LMS, implementation procedure of LMS, and assessment of LMS. In addition, it is also necessary to analyze whether the implementation of LMS is justified. However, it is believed that such fundamental issues are not yet addressed completely in the literature of LM. Hence, there is a need to study the design and assessment of LMS. newline this research, a detailed literature review is carried out to understand the current status of LM and to identify the research gaps. To resolve some of the research gaps, a comparative analysis of various LM frameworks and frequency analysis of the LM elements is performed based on which a conceptual framework for LMS and an implementation framework for LMS is proposed. The proposed frameworks are validated using a case study. Similarly, a frequency analysis is carried out for to identify the performance measures of LM based on which a new Performance Measurement System (PMS) framework for LMS was proposed by modifying the balanced scorecard approach.
INTRODUCTION Women constitute about half of the population of any country, but their involvement in politics is insignificant as compared to that of men. A democratic country cannot progress if the energies of half of its population are concentrated in the kitchen only.1 To understand the status of women in society an examination of their political status is necessary. As political status is interlinked with socio-economic status, it has the capacity to influence the transformation of the socioeconomic system of the country. It has now been accepted that women's right to vote and occupy positions in society is fundamental to women's status.
In the last decade, social media has emerged as a front-runner as a communication medium that allows people to connect at a global level by breaking the geographical barrier and enabling e-participation of people through these social media platforms which act as a virtual world. Due to the above reasons, social media has become an integral part of our lives and we use these for almost everything, ranging from news, entertainment, recommendation on products, and connecting with friends and family. This obsession is so high that out of all Internet users, 75% use social media in one way or the other. People are so much attached to this virtual world that almost every day on average, one spends at least two hours on social media. Currently, there are around 2.9 billion active social media users worldwide. These active users are continuously posting messages, images, videos, etc on various social media platforms and generating tons of user-generated content (UGC).
