Nuclear Magnetic Resonance Spectroscopy NMR

By Dhaval Chudasama, Gaurang Patel

Abstract: Nuclear magnetic resonance is a type of spectroscopy. It is necessary to know for which atom it is active and for which atom it is inactive. How the nuclear magnetic resonance process takes place is important. We can therefore say that nuclear magnetic resonance spectroscopy is used to elucidate the composition of carbon atoms and crystals as well as non-crystals. And nuclear magnetic resonance spectroscopy can also be applied to …

Density and Interaction Data for Lutetium-Yttrium Ortho-Aluminate- Based Scintillation Crystals for Gamma-ray Spectroscopy and Imaging

By Luca Indovina, Raffaele Scafè, Marco Puccini, Rosanna Pellegrini, Roberto Pani

Abstract: The density values of (LupY1-p) AP scintillators based on the results of a literature survey have been found strongly positively linearly correlated to the value of the parameter p, that represents the ratio of lutetium vs. yttrium oxides content by weight. Two cases of serious lack of information have been investigated to search reliable data. Further studies are in progress aimed at inferring possible unknown compositions by using the data …

Efficient PCB Fault Detection System using Deep Learning and Image Processing

By Tanmay Ajay Sarode, Kalpant Chitteshwar Ruikar, Gaurav Kundan Raut, D. M. Bhalerao

Abstract: Printed Circuit Boards (PCBs) are essential parts that support the operation of electronic equipment in a variety of sectors. Nevertheless, difficulties that manufacturers regularly face during the PCB manufacturing process lead to defective devices. However, current inspection processes occur after etching, wasting a lot of material and rendering defective PCBs unusable. This study discusses relevant practical difficulties and offers a method for identifying errors in real PCB images using Matlab …

Radiation Effects in Acrylonitrile (AN) Ethyl Methacrylate Copolymer by Spectroscopic and Thermal Methods

By B. Sanjeeva Rao, D. Suresh, S. Kalahasthi, V. Sridhar

Abstract: Gamma irradiation effects in acrylonitrile (AN) ethyl methacrylate (EMA) (AE) copolymer have been investigated by electron spin resonance (ESR), Fourier transform infrared (FTIR) and differential scanning calorimetric (DSC) techniques. Temperature and radiation dose dependent effects have been investigated by recording ESR spectra under different conditions. Computer simulation techniques are used to analyze ESR spectra to identify of free radical produced on irradiation of copolymer. As such, ESR spectrum of irradiated …

Mass Production Tools and Process Readiness for Uniform Parts—Injection Molding Application

By Boorla S Murthy, Tobias Eifler, Thomas J. Howard, Chris McMahon

Abstract: A mass production always aims to produce uniform performing products. Production tools such as pressing dies, casting dies and injection moulds, play a significant role by producing uniform parts for achieving final products. Tool complexity increases when multiple cavities are present. These tools pass through several stages of quality maturation, before starting production, where the tool capability for part uniformity can be assessed, corrected and aligned to mass production variables. …

Capability Database of Injection Molding Process—Requirements Study for Wider Suitability and Higher Accuracy

By Boorla S Murthy, Tobias Eifler, Jens Dines O. Jepsen, Thomas J. Howard

Abstract: AbstractGenerally, there is little disagreement that an early consideration of dimensional accuracies achieved in production is conducive to the success of development of injection molding products. While different process capability databases (PCDBs) provide guidance for a meaningful estimation of the expected part variation, the adoption of corresponding guidelines and (proprietary) software tools seems to be, however, limited in industrial practice so far. This research paper addresses the gap between the …
