Abstract– In this research, we extant a short outline of Information Extraction, which is also a natural language processing domain that tries to find required information in structured, semi structured and unstructured Data. We draw a taxonomy of information extraction tasks and techniques. The other important thing is that we also extract learning methods like supervised, semi supervised and unsupervised learning and which methods are used in these types of learning. Our domain analysis consists on social media, Biomedical, chemical and unstructured data. There are different tasks included in information extraction which makes this activity more manageable as well as to easy to work in specific domain. We also detect weakness of existing techniques.

Abstract– Municipal Solid Waste (MSW) management has become more complex and costly with rapid socioeconomic development and increased waste volume. In this context, stand out Construction and Demolition Waste (C&D), considering that, they represent a large part of the solid waste generated in the urban environment. One of the main impacts faced by municipalities in relation to construction waste is associated with the irregular disposition of the enormous quantities produced and the expenses of the public administration with corrective management models. This study aims to present an overview of the current reception locations of C&D in the city of Brazil (Belo Horizonte), evaluating its efficiency in municipal management. In order to reach the proposed objective, references were used based on reports from the municipality and through bibliographical research, carried out in articles, municipal management plan and current legislation. Based on the results obtained, it can be seen that the municipality has a good structure for the management of C&D, in accordance with the requirements of CONAMA Resolution No. 307/2002. However, although SLU provides appropriate waste reception facilities, it is still possible to see several locations of irregular C&D disposal. It is concluded that there is a great deficiency regarding the measures related to the non-generation, the minimization, the disposition and the reutilization of the C&D generated in the city. Finally, it is suggested some measures that could be adopted to improve, especially related to the current areas of reception, the management of C&D in the city of Belo Horizonte.

Abstract– This study prepared, characterized maize-starch based cutting fluids and examined its effect combined with some machining parameters on heat generated during turning of AISI 304 stainless steel with a view to determine the suitability of the maize-starch for use as cutting fluid. The maize-starch cutting fluids were prepared by mixing 10% of soluble and coconut oils with maize-starch paste. Other cutting fluids used were water mixed with soluble oil and straight coconut oil. The viscosity, specific gravity of each cutting fluid and temperature at the cutting zone were determined. The results show that the kinematic viscosities for soluble oil, coconut oil, maize-starch mixed with soluble and coconut oils were 38.0, 37.98, 36.04 and 35.44 cSt, respectively. Also, the specific gravities for the cutting fluids were 0.99, 0.92, 1.06 and 1.06, respectively. Increases in depth of cut, cutting speed and feed rate increases the temperature produced at the tool-workpiece interface while increases in cutting fluid flow rate reduces the temperature using the four cutting fluids. Likewise, the maize-starch mixed with soluble oil demonstrated the best fluid since it gave the lowest temperatures at all levels of depth of cuts, fluids flow rates, cutting speeds and feed rates when compared with the other cutting fluids used. Therefore, if coconut oil could be used as a coolant in machining process, certainly, this study suggest that maize-starch mixed with soluble oil is suitable and superior to the other fluids with respect to lubricity and cooling effect when used in turning AISI 304 stainless steel.

Abstract– In this research work, for establishing a modern electrical design and installation of equipment of high rise building two new appliances have been proposed. The first one is usage of busbar trunking (BBT) system for main distribution line instead of conventional wiring system to provide much higher protection, easier installation process, reduce cost, time, space, and maintenance management. The second one is continuous fault analysis and monitoring using SICAM Q100 device which is the updated process to make sure more safety for monitoring power quality to acquire, visualize, analyze, and transmit measured electrical variables such as AC current, AC voltage, frequency, power, harmonics, etc. The measured variables can be output to a computer or control center via communication interfaces or shown on a display. Total electrical drawing has been drawn in AutoCAD. An entire substation for the high-rise building has been designed, according calculated load of the building. For protection of the building proper rated MCB and MCCB has been installed according to the load. To avoid fire hazard, fire detection and alarm system with immediate water supply has been installed in this building. Entire electrical connection has been designed based on Bangladesh National Building Code- 2014 (BNBC).
