Study of 3MeV DC Electron Beam Accelerator to implement Distributed Control System

Electron beams with beam energy in the range of 0.2 to 10 MeV have found a large number of industrial applications such as cross linking of plastic film, foam and cables, degradation of scrap Teflon, sterilization of medical products and food irradiation. Keeping these industrial applications in mind, the development and commissioning of a 3 MeV accelerator is being done at Electron Beam Center at Kharghar, Navi Mumbai. The accelerator comprises of several sub systems such as Scan magnet supply, Chiller unit, Vacuum unit, High voltage unit and other support sub-systems. All the above subsystems have to be controlled from central location in order to operate and monitor the accelerator safely. Each of the sub-system is controlled by a Programmable Logic Controller (PLC) independently and their control and safety is ensured by the program logic. After each subsystem is tested separately all the PLCs are connected to the central PLC via Modbus RS232 and Modbus TCP-IP to implement the technology of Distributed Control System (DCS). A DCS refers to a process in which elements from different locations can be controlled by inputs from a remote place by different modes of control implementation

A Parallel Environment Designing for OWL Thinking

A huge volume of information available today is in the form of images and searching the wanted images is very difficult and highly time-consuming. The search may take longer periods as the search volume on the internet is very huge and also the relevance of extracted images is still not up to the mark. The technologies like ontology and languages like OWL help us to tag the images that describe the semantic of the images. Hence, it helps in faster searching of the wanted images. Also, another challenge with OWL and Semantic web is the speed in which one can derive the relationships between various objects extracted from the images. The challenge is to extract the semantic from the images more efficiently using a parallel approach. In this paper, we explore the different techniques for generating semantic knowledge using parallel approaches like the T-box approach, merge classification, extract concept for matching ontology. We propose an enhanced method to speed-up the computation by combining T-box and merge classification techniques

COMPACT ULTRA WIDE BAND ANTENNA WITH BAND NOTCHED CHARACTERISTICS.

A compact ultra wide band antenna with band notched characteristics is presented in this paper. Single band notch is created in 5.4 GHz to 6.4 GHz frequency region with the help of two C shaped slots in order to reduce the interference in WiMax and X-band systems. A good return loss (S11) values have been noted in WiMax (5.1 GHz to 5.8 GHz) and X-band (7.1 GHz to 7.7 GHz) frequency range. The designed antenna covers the ultra wide band range of 3.1 GHz to 10.6 GHz which has VSWR less than 2 and the return loss is less than -10db and has an omni-directional radiation pattern. The designing and simulation results are done by using ANSOFT High Frequency Structure Simulator. A prototype was fabricated on FR4 substrate and measurements were done using Agilent N9916A Fieldfox handheld vector network analyzer

Inability to Read After Prolonged COVID-19 Hospitalization: MRI With Clinical Correlation

Coronavirus Disease 2019 (COVID-19) is a viral condition caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Studies suggest that SARS- CoV-2, such as most coronaviruses, is capable of invading the central nervous system to exacerbate or cause neurological disease
