Highlights

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.

Highlights

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.

Highlights

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.

Highlights

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.
