Plasma nitriding treatments are applied to achieve excellent surface properties on steel parts and tools. Active screen plasma (ASPN) does not have the defects presents in direct (DCPN). However, ASPN require much longer processing times develop layers as deep those of DCPN. This work development a biased treatment system, investigate possibility achieving greater efficiency. The were performed...
Addition of titanium (Ti) to ASTM A710 Grade B Cu-precipitation-strengthened steel significantly increases the impact absorbed fracture energy and reduces the ductile-to-brittle transition temperature. The effect of Ti correlates with the reduction of the amount of pearlite in the ferritic microstructure. A thorough study of the mechanical properties of Ti-modified A 710-B steel is presented.
The smoothness of the pavement surface approaching a Weigh-In-Motion (WIM) scale directly affects the device’s ability to accurately estimate static loads from measured dynamic forces. Lack of smoothness creates difficulties in obtaining an acceptable weighing error. Efforts were made in this study to determine appropriate threshold values of profile length and roughness approaching the WIM. Ro...
Tracking is the main factor which limits the safe working electric stress of insulation in power system applications. Polymer samples have been tested in laboratory conditions according to ASTM D2303 on accelerated inclined plane tracking test. In this paper, a model based on improved Weibull statistics is proposed for estimating the breakdown time of polymeric insulating materials with borax. ...
This study was aimed to study the probability about the production of fiberboard made of durian rind through latex with phenolic resin as binding agent. The durian rind underwent the boiling process with NaOH [7], [8] and then the fiber from durian rind was formed into fiberboard through heat press. This means that durian rind could be used as replacement for plywood in plywood industry by usin...
Sharing of healthcare related information among the different healthcare providers is a crucial aspect for the continuity of the provided care The purpose of this study is the presentation of a system appropriate to be used upon the transition or the referral of a patient, and especially in transition from hospital to homecare. The function of the developed system is based upon the creation of ...
