The reliability of the software chip is the essential factor in VLSI design since the chip can be implanted in any embedded circuit varies from simple adder to crucial satellite device. Thus breach in VLSI chip operation may results in huge negative impact devastation. A novel architecture of VLSI chip testing design is proposed and unlike from normal BIST structure this structure ensures the safety of entire aircraft by monitoring the flow of signals around aircraft and controlling various part of the system for better security. ERRIC architecture is initially proven to be best testing and controlling structure for aircraft applications. Performance analysis of area, power, and timing constraints has been proved better using Quartus - II synthesizer tool. A method of Nios Processor controlled aircraft safety is ensured as a new proposal. Nios processor design has the unique advantage of high accuracy and flexibility over reconfigurable Network on chip applications.

In this work, complete preparation of nanocomposite were discussed. Here a urea-formaldehyde polymer matrix was synthesized and melt blended with nanohydroxyapatite in order to quantify their effect on mechanical behaviour of the resulting polymer composites. Here urea-formaldehyde resins are epoxidised through the hydroxyl groups by treatment with epichlorohydrin. Nanocomposites were mixed with hexamethylenetetramine (HMTA) which was used as curing agent. The composites were shaped through compression moulding machine according to the ASTM std. The morphological characters were found through the synthesized powder using SEM and XRD analysis. The mechanical properties like tensile strength, hardness were discussed for the composite. © Research India Publications 2015.

In this work, 12 mm diameter AISI 1035 grade steel rods are friction welded with an aim to optimize the process parameters. The joints are made with various process parameter combinations (incorporating ANOVA methods) subjected to tensile test. The empirical relationships are established to predict the ultimate tensile strength, notch tensile strength, and % of elongation of the welded joints. The consistency of the model has been checked. The tensile properties, micro-hardness, microstructures, SEM, and the EDAX of the welded specimens have been studied and presented in this study. © 2014 Elsevier Ltd. All rights reserved.

This paper presents the wear behaviour of Al6061-T6 discontinuously reinforced with silicon carbide (SiC) and aluminium oxide (Al2O 3) composite. The test specimens are prepared and tested as per ASTM standard. The experiments are conducted by using a pin on disc wear tester. Empirical relation is established to estimate the wear using statistical regression analysis and analysis of variance (ANOVA). The results indicated that the wear resistance of the 15% hybrid composite is better than that of the 5% composite. The fracture surface of composites shows the ductile tear ridges and cracked SiC and Al2O3 particles indicating both ductile and brittle fracture mechanism. © 2013 Elsevier Ltd.

In this work, friction welding of AISI 52100 grade carbon steel rods of 12mm diameter was investigated with an aim to analyze the sensitivity of Tensile strength for the process parameter. Welds are made with various process parameter combinations using ANOVA design matrix which were subjected to tensile tests. The Ultimate tensile strength of the welded joints has been reported. A microstructure analyses were carried out to acquire the joint efficiency. The various zones of the microstructure have been shown in the optimized condition. © 2014 IEEE.
