Mounting machine is the most critical equipment in the SMT (Surface Mounted Technology), the production efficiency of which affects the entire assembly line's productivity dramatically, and can be the bottleneck of the assembly line if poorly designed. In order to enhance the VM(Virtual Manufacturing) of mounting simulation for PCB(Printed Circuit Board) circuit modular, the virtual reality sim...

Air quality data collection near pollution sources is difficult, particularly when sites are complex, have physical barriers, or are themselves moving. Small Unmanned Aerial Vehicles (UAVs) offer new approaches to air pollution and atmospheric studies. However, there are a number of critical design decisions which need to be made to enable representative data collection, in particular the locat...

In this work, the aerodynamic and structural design of fairing for vehicles was carried out. The Rankine half body theory, which is one theories being used aircraft gas turbine engine inlets turboprop nose cones adopted design. glass fabric composite materials were performed by analyzing loads. Structural analysis based on results to investigate safety. manufactured applying resin transfer mold...

The present study aims at investigating the amount of exhaust gases emissions of a 4-cylinder gasoline-ignition engine. An experimental study of an ignition engine management system has been conducted for emissions optimization, using Winols specialized software. In order to achieve a steady state conditions in the experiments, the temperature of the water and engine oil before each test reache...

basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. an efficient approach to studying cooling system for diesel engine is a 3d computational fluid dynami...

in internal combustion engines, only about a third of the total fuel input energy is converted into useful work. if the energy rejected into the cooling system and the exhaust gases could be recovered instead and put into useful work, fuel economy would have been substantially improved. the main aim of this research paper was to evaluate the effects of the hybrid nano-catalyst containing cerium...
