The term automation has many definitions. Apparently, it was first used in the early 1950s to mean automatic handling of materials, particularly equipment used to unload and load stamping equipment. It has now become a general term referring to services performed, products manufactured and inspected, information handling, materials handling, and assembly—all done automatically (i.e.as an automatic operation without human involvement). At present, in order to solve the low efficiency and high cost problem in the process of CNC machines, Nowadays Manufacturers have always faced the challenge of constantly needing to find new ways to reduce the cost of their loading and unloading processes in machining centers. The project title is “LOW COST AUTOMATION FOR MACHINING CENTER” new concept in Machine tool industry for continuous production, less cycle time and more accuracy. This project contains the auto loading plate, unloading plate, hydraulic fixture and rotary table controlling with PLC Ladder logic controller.It is a simple automation system for auto load and unload component to vertical CNC Machining center as compared to the gantry auto load and unload system.

The security is an important aspect in our daily life whichever the system is considered, security plays vital role. The biometric person identification technique based on the pattern of human iris is suitable to be applied to access control and provides strong e-security. Iris recognition is one of important biometric recognition approaches in human identification is very active topic in research and practical application. Iris Recognition System consists of Acquisition, Localization, Feature Extraction and Feature Matching phases. Circular Hough Transform is one the best suitable algorithm in segmentation phase, but as a result of having two for-loops in its structure; CHT algorithm consumes high time processing and uses high storage capacity. These drawbacks make it hardly appropriate for real time applications of iris recognition system. To improve time and storage complexity, firstly, a pre-processing of CUHK iris image dataset is done to eliminate unnecessarily regions and secondly, a radius table is created based on pupil size variation of CUHK iris image dataset. The results show at least 40% efficiency in time complexity and minimum 20% efficiency in storage complexity.
The purpose of HVAC system is to provide and maintain a desired indoor thermal comfort. HVAC system inherents nonlinearity of the large scale system including pure lag time, big thermal inertia, uncertain disturbance factors and constraints which lead to inability to efficiently control this system. Furthermore, there is no combined model developed for the comprehensive HVAC system. This book addresses these issues by proposing a hybrid model combining building structure with the equipments of HVAC system in one model. The hybrid identification of physical and empirical methods is explained where empirical Residential Load Factor is used to calculate a buildings load. The indoor thermal sensation identification is using a TS fuzzy model based on PMV and tuned by Gauss-Newton Method. To control such sophisticated system, a new online-tuned TS Fuzzy Forward controller is proposed. This algorithm manipulates inputs of AHU based on optimization of inputs of PMV sensor. An important finding in this book is the conversion of a fuzzy inference system for PMV and control model into memory layers parameters. This approach is computationally faster and efficient than traditional methods.
High efficiency of power converters placed between alternative energy sources and the utility grid is required to maximize the utilization of these sources. Power quality is another aspect that requires large passive elements to be placed between these sources and the grid. This book, therefore, provides the different modern technologies for energy efficiency improvement and develops a higher-level high frequency power converter system (HFPCS) that optimizes the use of hybrid renewable power injected into power grid. HFPCS provides high efficiency, reduced size of passive components, higher levels of power density realization, lower harmonic distortion, higher reliability, and lower cost. Dynamic modeling for each part is developed, simulated and tested. Steady-state performance with battery storage is analyzed. Various types of algorithms are developed and tested to verify the effectiveness of the power conversion topologies. The developed HFPCS is compared experimentally with other currently available power converters. HFPCS is also employed inside a microgrid system infrastructure, connecting it to power grid to verify its power transfer capabilities and grid connectivity.

This monograph presents a high efficiency RF to DC converter. The technique exploits an internal Vth cancellation along with a leakage current reducer. The work demonstrates methods to reduce the threshold voltage of a transistor and reducing its leakage current. It further discusses techniques to reduce sub-threshold leakage current and enhance the power conversion efficiency.
Due to the growing demand for electrical energy and environmental impact such as global warming and pollution, photovoltaic (PV) energy generation system has been considered as a technological option for generating clean energy. The advantage of PV system is that it is pollution free, but it still has relatively low conversion efficiency from solar irradiation to electric power. Power delivered by the PV system depends on several environmental factors such as lighting conditions, temperature and shading. The nonlinear characteristic of PV array, the fluctuating output power which varies with temperature and irradiation and losses in power conditioner devices are among the drawbacks of PV systems. An important consideration in increasing the efficiency of PV systems is to operate the system approximate to the maximum power point (MPP). This book discussed a new high performance maximum power point tracking (MPPT) controller by using a new boost converter and a new intelligent MPPT algorithm.

Position-aware applications such as navigation tools for humans and robots, interactive virtual games, resource discovery, asset tracking, position-aware sensor networking etc. require precise positioning. These indoor applications require better accuracy than what current outdoor positioning systems provide. This book presents some new algorithms for position estimation in RFID, WSN and VLC technologies. We design some RSS positioning algorithms for RFID and WSN using flexible models. Using the time difference of arrival (TDOA) and RSS measurement functionally of a commercially available RFID system, a position finding algorithm is presented where the position is estimated in two steps. As a practical application of this system, an automatic parking management system is described in this book. For positioning in WSN, RSS based algorithms with flexible model of multi-layer parceptron and generalized regression neural networks are proposed. This book also demonstrates a robust, high accuracy positioning algorithm using VLC and image sensors for precisely locating movable objects, like autonomous robot inside the building.
