Image Super Resolution Using Back-Projection based on Canny Edge Detection and Gabor Filter Prior
Abstract: In recent years, due to the advancement of mixed media instrumentation and machine gadgets, single-image super resolution has currently been converted into a thought subject. Super-resolution is the procedure of improving a high-resolution image from varied low-resolution pictures of a similar scene. The key goal of super-resolution imaging is to reproduce a higher-resolution image focused around a group of pictures, procured from a similar scene and indicated as “low-resolution” pictures, …

Design and CFD Analysis with Experimental Testing of Exhaust Manifold
Abstract: The exhaust manifold undergoes back pressure problems. If the design of the manifold consists of sharp edges or bends which will tend to create turbulence and increase in pressure. Due to increase in turbulence it can cause an increase in back pressure. As the back pressure increases it tends to improper scavenging of the exhaust gases. So the improper scavenging of the gases leads to improper burning of fuel which …

Design and Ballistic Performance Assessment of Pattern-Optimized Lightweight Composite Armor Using ANSYS Explicit Dynamic and AUTODYN
Abstract: This study investigates the ballistic performance of lightweight composite armor panels designed to defeat 9 mm full-metal-jacket (FMJ) threats using high-fidelity numerical simulations. Four different composite materials were arranged into panels of identical overall dimensions; only the internal segment pattern was varied to explore geometric resistance effects while keeping mass and material type controlled. Ballistic impact simulations were performed using ANSYS Explicit Dynamics and AUTODYN to capture high-strain-rate behavior, local …

Evaluation of Image Reconstruction Techniques in Single Photon Emission Computed Tomography (SPECT/CT) Imaging
Abstract: AbstractThis work is aimed at evaluating the image reconstruction techniques used in single photon emission computed tomography (SPECT/CT) imaging. The reconstruction techniques considered in this work are: the ordered subset expectation maximization (OSEM) and the Filtered Back Projection (FBP). An anthropomorphic torso phantom with lung and liver inserts was injected with 99mTc. The liver and the background were given 0.2 MBq/ml and 0.07 MBq/ml respectively. The lungs inserts were filled …

Feasibility of adopting various tools in design phase management for construction projects
Abstract: Managing the design process across the course of a project's lifecycle is known as design phase management. Due to the iterative nature of the design phase, several types of variability affect workflow in construction and present management problems to the project team. In this study, the stakeholders were interviewed in-depth to identify the coordination issues that arise during the design phase of each stage of the building project. Based on …
