Identification of Accident Hot Spots at Different Roads of Midnapore Municipality Area: A Geoinformatic Approach
Abstract: Road traffic injuries (RTIs) are a huge public health and development problem, killing almost 1.2 million people a year and injuring or disabling almost 20 to 50 million or more. Both WHO and World Bank data show that without appropriate action these injuries will rise dramatically by the year 2020, particularly in rapidly-motorizing countries. The study identifies the volatile traffic areas where road accidents are almost regular events and assess …

Modification of gating System of Ball Valve Component using Soft-cast Simulation
Abstract: There are two main important considerations in castings are quality of the casting and yielding of the casting due to which scrape of material will reduce. Production of good quality casting mainly depends upon the gating system. In casting process gating and risering system has direct effect on its quality. Generally, many industries follow the trial and error method for casting process which is not economical for foundries for long …

Autonomous Optimization, Method Design of Casting and Its Experimental Validation: A Case Study
Abstract: The metal casting is a complicated but a mass production manufacturing technique. But on the otherhand, the chances of casting rejection are also more if proper attention is not made at every stage ofcasting production. In the metal casting process, higher yield and minimum defects level are expectedby the foundry industries. In the present global and competitive world metal casting industries needsto perform efficiently with a reduction in rejections. This …

Monitoring and Modeling of Atmospheric Change Indices In Parts of Imo State Using GIS, MATLAB and ANN
Abstract: Geographic Information System (GIS) and Matrix Laboratory (MATLAB) Models were used to study air quality in parts of Imo State. Primary data were obtained by conducting relevant analysis using standard instrumental methods on open-air rainwater samples collected in the dry and the rainy seasons for two consecutive years. GIS showed that the pollutants were present throughout the year. Artificial Neural Network (ANN) of MATLAB 2015 was used to represent data …

Inverse Model for Predicting Thermal Abnormality of the Transient Process Triggered by Defective Electronics Element
Abstract: The paper presents a model for predicting thermal abnormalities in Printed Circuit Boards (PCBs) by approximating the thermal process of electric elements with heating from point sources. Circuit board heat sources are defined as point and non-point. The point heat source is a small electronic heating element that can be approximated as having originated from one point on the circuit board. A non-point source is one with heat distributed over …

Microwave Curing of Glass-Epoxy Composites Using Silica Based Moulds
Abstract: AbstractFor polymer composite product manufacture, curing of the fibre reinforced polymers (FRP) is a critical step in achieving desired mechanical properties. The conventional cure processes involve thermal curing in hot air ovens and autoclaves where the cure process is time and energy intensive. In this context, microwave curing is one of the most promising processing methods since it results in substantially reducing cure cycle time, energy requirements and operational costs …
