 Abstract

The CRNO steels are used as core materials in electrical motors and transformers. Key properties governing the efficiency of the components are low core loss and high permeability. 50C600 grade with Si % between 1.3 to 1.4 is one of the most common grades in India. Variation in permeability (B50) was found in this grade, with variation from 1.65 Tesla to 1.70 Tesla. Detailed investigation was carried out to find the factors affecting the permeability. The most notifying source was found to be average inclusion size. Inclusions deteriorate the magnetic property by pinning the motion of domain walls. Presence of inclusion above 10 ?m resulted in lower permeability. Subsequently use of diffuser in tundish was experimented for forced flotation of inclusions. Optimum gas flowrates were calculated mathematically and further adjusted with a series of experiments. Bubbling was kept normal and the back pressure was maintained constant during the sequence casting. Average inclusion size reduced from 12 ?m to less than 8 ?m in HR coils with the use of diffuser. In the coils having lower inclusions, average permeability improved from 1.68 Tesla to 1.7 Tesla in the coils produced with the use of diffusers.

 Abstract

Rapid changes in technology, specifically knowledge-based technology, have inspired innovation in the use of tools to deliver instructional teaching and learning materials. Therefore, teachers need to be ready to utilise technologically driven supporting materials that focus on how and what pupils learn in an environment that is engaging. Therefore, this Design and Developmental research investigated the development of a stop-motion video as supporting material for teaching History to 63 Form One secondary school students. Results from phase one showed encouraging and positive feedback from students when two of the History teachers used stop-motion videos as teaching and learning material during their class. The data collected investigated the Need Analysis for History teachers in using stop motion for their classes. A semi-structured interview was employed with four History teachers and their responses were transcribed verbatim.

 Abstract

Converters are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high- voltage direct current applications that transport bulk power. Boost derived hybrid converter is use to supply both AC and DC load from the single input. The report of the project is based on the performance of MOSFET based model for boost derived hybrid converter with Sine-PWM technique. Unipolar Sine -PWM technique is apply for boost derived hybrid converter. Switching logic for generation of pulses on the basis of Sine-PWM is developed and simulated. Simulation of boost derived hybrid converter with resistive load is covered. A control card of pulse generation for boost derived hybrid converter is developed LM 324 Op-Amp and logical gate IC and tested. The main features of controller for SPWM generation are simpler in design, low in cost, and maximum range of voltage control and compact in size. Better accurate results are achieved in switching logic. Boost derived hybrid converter is simulated in PSIM software. The driver circuit is fabricated with required protection. The obtained results show the required performance of that circuit. Open loop testing of boost derived hybrid converter is done in proto type. The waveform at each stage of power circuit and control circuit are observed for verifying the required output and results obtained are as per requirement.

 Abstract

Induction machines are the widely used machines in many industrial applications. Enlistment machines are generally utilized as a part of enterprises because of its ease and least upkeep. In more electric aircraft (MEA), both ac and dc electric power with different voltage levels is required for different airplane loads. This paper introduces an enlistment generator-based ac/dc crossover electric power age framework for MEA. In the proposed system design, a fast enlistment starter/generator and a low-speed acceptance generator are introduced on the high pressure (HP) and low pressure (LP) spools of the motor, separately. In creating method of activity, the bigger part of the steady voltage variable recurrence ac power is produced by the HP generator while the dc control request is shared by both HP and LP generators. A control conspire is produced to manage the ac stack voltage and organize dc control age between the two generators. The proposed induction generator-based ac/dc hybrid generation system outcomes in reduced hardware requirement compared with both ac and dc primary generation systems.

 Abstract

ABSTRACT: Therapeutic drug monitoring could be a branch of clinical chemistry and clinical pharmacology that specifies within the measurement of medication levels in blood. Its main fixate is on drugs with a narrow therapeutic range.TDM begins when the drug is first prescribed, and involves determining an initial dosage process relevant for the clinical condition and such patient characteristics as age, weight, and collateral drug therapy. When interpreting concentration measurements, factors that require to be considered include the sampling time in reference to drug dose, dosage history, patient response, and therefore the desired medicinal targets. The goal of TDM is to use suitable concentrations of medications to optimize clinical outcomes in patients in various clinical situations.

 Abstract

Information technologies have a major role in the way people work, live globally. Today libraries are well furnished to provide the newly Information Technology services. Information Technology enabled services to complete the information needs of the users at the right place, time, and the right person. ICT has brought incomparable changes to library and information services, such as OPAC, user services, reference services, current awareness services, interlibrary loans, and customer relations can be provided more professionally and successfully using ICT. The paper attempts to discuss the rapid growth of information technology in the library services and the many problems faced by the LIS field in India and the success of many years using digital technologies.
