The field of mechatronics includes wide range of applications such as development of robot, embedded system, integrated high temperature material processing, controlling of electrical and fluid power actuators. Electro-pneumatic systems are taking a special role in automatic production processes such as food, beverage, plastic industries and many others. The fault detection and control of sequential operation based on fluid power actuators has always been challenging. This paper takes the case study of electro-pneumatic actuator role and its control in the sequential operation for automatically punching and placing the materials in the predefined states. The controlling of sequential operation has been carried out using PLC as well as relay, contactor, solenoid and watchdog timer. Also, in this paper the required actuation system is designed and simulated using Automation studio and it has been carried out experimentally with different fault detection cases.

Arithmetic circuits form an important class of circuits in digital systems with the remarkable progress in the very large scale integration (VLSI) circuit technology, many complex circuits, unthinkable yesterday have become easily realizable today. Algorithms that seemed impossible to implement now have attractive implementation possibilities for the future. This means that not only the conventional computer arithmetic methods, but also the unconventional ones are worth investigation in new designs. In this thesis an ARITHMETIC UNIT based on IEEE standard for floating point numbers has been implemented on Spartan3E FPGA Board. The arithmetic unit implemented has a 32-bit processing unit which allows various arithmetic operations such as, Addition, Subtraction, Multiplication, Division and Square Root on floating point numbers.Each operation can be selected by a particular operation code. Simulation of FLOATING POINT ALU has been done by XILINX-ISE.

Master Data Management (MDM) is a set of techniques and procedures (shared with Data Integration tools) put in place to collect raw data from several internal and external sources, conduct data quality analysis and profiling. cleanse them, combine/merge to provide “Single Source of Truth” and 360 view of a business entity and redistribute to internal transactional and business intelligence systems. MDM is useful in Business Intelligence world primarily for managing Dimensions in a typical Data Warehouse setup. Majority of the MDM deployments use MDM as the hub to supply Dimensional data to several downstream systems like Data Warehouses and Data Marts within the organization to facilitate reuse of unified/standard set of Dimensions across several reporting systems. Most of the MDM tools are also equipped to suck in data from several types of both external and internal data sources and redistribute the constructed Dimension data to several types of downstream destinations in both batch and real-time. Current MDM solutions are also usually accompanied by Data Quality and Data Profiling tools to assist during Data Preparation process.

The comparative microstructural and mechanical characteristics of fusion welds (Tungsten Inert Gas - TIG) and solid-state welds (Friction Stir Welding - FSW) of aluminum alloy 7075-T6 (AA7075-T6) are investigated in this paper. Microstructures of base metal and welded zones are analyzed by optical microscopy. The mechanical properties of welded joints are evaluated through hardness measurements and uniaxial tensile tests. The experimental results shown that the TIG welded joints are often cracked along the joins. The grain size grows in welded zone of TIG are dramatically coarser than that of FSW. Furthermore, comparison with the base metal, both the hardness and tensile strength in the welded TIG are reduced significantly in comparison with those in the FSW. Specifically, the tensile strength of the TIG and of the FSW welded joints is approximately 42% and 70% that of the base metal, respectively.

Seasonal variation of indoor radon, thoron and their progeny concentrations have been measured in different types of buildings at different locations of Belur and Channarayapatna taluks using time integrated passive radon dosimeters containing LR-115 Type II solid state nuclear track detector. The average radon and thoron activity concentrations, their progeny levels, life time fatality risk and annual effective dose due to radon and thoron were estimated in summer, rainy, autumn and winter seasons. A detail analysis of radon and thoron distribution in twenty different houses with seasonal variation is presented in this paper. In general, the levels of radon and thoron concentration were observed to be highest in winter and lowest in summer.

With the increased pollution levels and global warming, people are getting more aware of this persisting problem. This is causing a great push for the demand of renewable energy. The trend started with electric vehicles, although this is a good step but still not enough. One of the most promising solutions is the installation of solar cells in household setups. With the tax credits and the installation of smart grids, which allow to recuperate some of the initial cost back, the equivalent cost of installing such systems is getting cheaper and thus becoming more feasible and within the budget of a lot of people. This paper, models the photovoltaic setup, the proposed system includes a battery bank, electric or a plugin electric vehicle, smart grid, and an array of photovoltaic cells. The proposed method also aims at maximizing the solar energy usage, or in other words reduces the amount of said energy that is going to waste by not having any active receiver at any given time of the day.

The various parameters included in the study are blooming phenology, breeding systems, assessment of temporal depletion and deposition of pollen under flower – visitors activity, natural fruit set, fruiting flower and pod length and seed number, weight at inflorescence level. The trees of Delonixregia bloomed after leaf shedding. It flowers during March – September. The period of blooming extended over 128.5 (R = 97 - 158) days. The flowers per raceme were 11-14. Flowers are bisexual and compatible for geitonogamous and xenogamous pollination. Flowers were compatible for geitono and xeno pollen. In observation for fruit set at inflorescence level by hand-pollination, most of the odd numbered flowers developed into fruit. There were no seed abortions. The number of fruits per inflorescence were being commonly 1 - 2. Mostly the third, fifth and seventh flowers transformed into mature fruits. Hand-pollination of geitono and xeno pollen resulted in fruit set. There is no fruit set through autogamy.
Magnetohydrodynamic heat transfer in the fully developed viscous flow of an ionized gas under the influence of a uniform transverse magnetic field with hall current, in different geometrical considerations and under varied conditions. It is assumed that the magnetic Reynolds number is small. The fluids in the two regions are assumed to be incompressible immiscible and electrically conducting with different viscosities and electrical conductivities. The governing differential equations are solved analytically, using the prescribed boundary conditions in both phases and obtained exact solutions for primary and secondary velocity distributions. Numerical calculations of the resulting solutions are performed and by varying the various physical parameters Hartmann number Ha, Hall parameter m, viscosity ratio, height ratio h, thermal conductivity ratio β on the behavior of heat transfer.
