Evaluation of Thermal Properties of the Fe80Cr20 Nanostructure for Interconnect Application in High Temperature

Metallic Fe80Cr20 alloy in thermal stability analysis is investigated. Approached method is combination technique (milled and UT) of ball milling (milled) combined with ultrasonic technique (UT) which is not yet fully explored. From Energy Dispersive x-ray Spectroscopy (EDS) analysis resulted that the composition of 80 wt% Fe and 20 wt% Cr in individual particle was achieved at milled and UB 4.5 h sample. Higher thermal stability of treated samples approximately 63% at 1100 °C temperature operation which showed by milled and UT at 4.5 h when compared to raw material. Combination technique shown high prospect to advance exploration in improving thermal stability which suitable for interconnect application.

Speed limiter integrated fatigue analyzer (SLIFA) for speed and fatigue control on diesel engine truck and bus

Every second, the number of road traffic deaths is increased globally with millions more sustaining severe injuries and living with long-term adverse health consequences. Jakarta alone in year 2015 had recorded 556 people died due to road accidents, approximately reached 6.231 road accident cases. The identified major contributory factors of such unfortunate events are both driver fatigue and over speeding habit especially related to the driving of truck and bus. This paper presents the idea on how to control the electronic system from input fuel system of injection pump and the combustion chamber engine will control the valve solenoid in injection pump which can lock and fuel will stop for moment, and speed limit can be success, by using sensor heart rate we can input reduce speed limit when fatigue detection driver. Integration process this tool can be relevant when Speed Limiter Integrated Fatigue Analyser (SLIFA) trial in the diesel engine for truck and bus, the result of this research Speed Limiter I...
