ATPG for 2D/3D wider Kogge-Stone Adder circuit

Abstract: It is an well established fact that 3D design has a number of benefits over corresponding 2D design, albeit with somewhat more design complexity. One key advantage is the reduced set of Test Vectors needed to test a 3D circuit as the design is spread over multiple planes, each plane having reduced size than the original design. When all the TVs across these layers are combined we still get a smaller set as the TV complexity increases super linearly with the size of the circuit. In this paper we designed 4-, 8-, 16-, 32- and 64-bit 2D KSA adder circuits. We created the 3D version of the corresponding KSA circuits using two planes, inserting necessary control points in the form of Scan flip-flops. We then used TetraMax to create ATPG set of Test Vectors for these circuits to detect stuck at and transition faults. We find that the 3D version enables us to use effectively a much reduced set of Test Vectors for pre-bond testing compared to the 2D counterpart at the same time with increasing fault coverage. This is in confirmation with some of the results published in the literature on this.

Stiffened Cylindrical Shell with Cutout

Abstract: Cylindrical shell panels made of laminated composites with cutout are investigated for free vibration behaviour. Finite element model is used for studying the dynamic behaviour of stiffened shells using eight-noded curved quadratic isoparametric element for shell and a three-noded beam element for stiffener. Size of the cutouts and their positions with respect to the shell centre are varied for different laminations and edge constraints. The results presented in the form of figures and tables are analysed to suggest guidelines for selection of optimum size and position of the cutout with respect to shell centre considering different laminations and practical boundary conditions.

Phase formation and Morphological features of Calcium Copper Titanate by Modified Solid State Process

Abstract: Perovskite calcium copper titanate posses giant dielectric constant making it a suitable candidate for possible applications in microelectronic components, advanced transistors, energy storage capacitors. Generally, this grade of material is synthesized by the chemical route to improving homogeneity, controlled size growth for enhanced properties. In the present research, a simple synthesis process was adopted using precursors of high purity oxides like Calcium carbonate, titania, Copper oxide without any use of complicated synthesis routes and costly chemical precursors. The molar ratio of oxides used was about 1:3:4 with mechano-chemical activation in an agate mortar for 20, 25 and 30 hours respectively in dry condition. After milling, powders obtained were made to undergo annealing at a fixed temperature of 900°C for 26 hours soaking period. Phase analysis was carried to determine the phase along with crystallite size calculation. Bonding information of the synthesized sample was analyzed to obtain the M-O coordination and vibration-stretching analysis of the bonds. Morphological features were also noted using FESEM (Field Emission Scanning Electron Microscopy) for understanding grains and granular boundaries. Both FTIR (Fourier Transform Infra-Red Spectroscopy) and XRD (X-Ray Diffractogram) analyses confirm the compound formation in terms of molecular structure responsible to obtain the proper phase.

Command and Control (C2) Network for Disaster Management

Abstract: A natural Disaster or a catastrophe is a sudden incident which disturbs the normal conditions or equilibrium of an area both intensively and extensively by threatening human life and property where resources required for combating the scenario substantially exceeds what is locally available. In this paper we present a technique of deployment of Command and Control (C2) Network to generate an effective response necessary to meet the constraint of the hour. Here we make an endeavor to analyze the existing systems, their merits and demerits and finally propose a network which will carry the command to control the situation in case of an incident. Initially, we design a hierarchical commanding jurisdiction or we use an existing one and then we fit our designed network into it so that the command can be directed to the incident area without any ambiguity. Next, we check the compatibility of the Command and Control (C2) network with an existing hierarchical administrative system as a case study.
