Electrical Component Measurement, Mechanics and Optics in Fundamental Physics - Laboratory Manual Volume-II |Book Publisher International

 

This fundamental laboratory manual from Volume II is provided on the experimental theory for the higher educational level that is especially triggered by the electromagnetic characteristics and nature of their components, such as capacitors, resistors, oscilloscopes, magnetism, and AC-circuits, into an experimental approach to be performed in the pre-college and higher levels. This manual gives the necessary details to perform the experiments. The experiments included are meant to offer a basic understanding of electronics and the magnetic concept of physics. Most of the experiments are designed to go hand in hand with the theoretical courses in physics being taught during the whole curriculum of the semesters. For some additional experiments away from the theoretical background of the experiment, the laboratory procedure and data sheet are arranged for each experiment session and are contained both in the previous Volume I and this Volume II books. Some additional experiments away from the theory courses are being raised to enhance the scope of learning beyond the interdisciplinary physics courses that will integrate science with technology. The necessary theory for this type of experiment is described in the manual in a self-explanatory manner. However, all efforts are made to clarify any doubts by the teachers in these laboratory classes.

Multiple Characteristics of Mouth Opening in Temporomandibular Joint Disorders | Chapter 11 | Medical Science: Recent Advances and Applications Vol. 8

 

The Temporomandibular Joint (TMJ) of the human body is a complex joint. Its movement is primarily controlled by the muscles of mastication along with other structures of the head and neck. Restricted mouth opening in itself is a symptom of TMJ disorders. TMJ arthritis is one of the common disorders found in this joint. Radiological investigations, including MRI, are beneficial in the diagnosis of TMJ Dysfunction. It is the most prevalent type of musculoskeletal disorder with different clinical features. Most common presentation is the limited mouth opening (LMO), which could be arthrogenic or myogenic in nature. This further leads to activity limitation of the subject suffering from this disorder. Use of the metal ruler to measure the limited mouth opening is a common assessment method, along with other simple and complex procedures to accurately measure the mouth opening at TMJ. The treatment of TMJ issues frequently entails a multidisciplinary strategy that includes behavioural, physical, and pharmaceutical therapies. Physiotherapy, cognitive behavioural therapy, occlusal splints, analgesics, and non-steroidal anti-inflammatory medications (NSAIDs) are common forms of treatment. Thus, mouth opening, an important function of TM Joint mostly affected by all TM Joint Disorders, is also an important indicator that diagnosis and management are necessary to prevent activity limitation.

On-Site Measurement of Partial Discharge: Investigating Characteristics through Rise Time Analysis | Chapter 3 | Theory and Applications of Engineering Research Vol. 6

This paper describes partial discharge (PD) characteristics for on-site measurement based on rise time waveform. The frequency of partial discharges (PD) is a significant factor concerning electrical insulation. The implications of this kind of PD characteristics are becoming increasingly important with the rapid development of the detection of PD signals in medium voltage. The rise times characteristics are used in insulation condition monitoring to keep getting earlier information about the insulation condition of the high voltage or medium voltage equipment. Currently, there is minimal research working on the characteristics especially rise time and due to this, it needs to further develop comprehensive characteristics of PD detection at such extreme conditions. An on-site PD measurement using Rogowski coil (RC) and MATLAB analysis focusing on rise times is presented here. Measurement was set up based on the IEC60270 standard and the circuit in the standard is followed. Insulation used in this work is XLPE type under 11 kV voltage stress and there were eight locations were performed in order to get a clear picture of the pattern. The overall result indicates that the rise times range is between 1.5 and 5 ns. The impact of rise time characteristics on the PD signal based on the real measurement is huge since the maintenance unit can perform measurement in a short time compare to the previous method. Specifically, the total number of PD measurement and severity range were shown with cable length. The rise time pattern always provide different value depending on level severity and frequency. However, when combining the result rise time from 8 substations measured, it provides a significant result. The finding is valuable for future PD measurement and detection at the site when the operator directly focuses on the range value to identify PD signals.

Multifunctional Device for Measuring and Monitoring Parameters of a Photovoltaic Module | Chapter 12 | Research and Developments in Engineering Research Vol. 4

 In this work, analyzes of existing devices for measuring the current-voltage characteristic were carried out in order to compare several devices. The purpose of this work is to develop a device for measuring the current-voltage characteristics of photovoltaic modules and the environmental factors affecting them. The paper discusses a system for monitoring solar module parameters that measure air temperature, module temperature, solar radiation, wind speed, current-voltage characteristic, maximum power point (MPP), efficiency, and fill factor (FF) and stores the data in a computer. The system is constructed around a programmable microcontroller with an analog-to-digital converter built in. The suggested system's program code also includes an algorithm for determining the maximum power point of the solar module. Because every parameter are taken into account automatically and written to the computer in the form of tables, the system performs all measurements in real time and is simple to use.  In order to compare the suggested monitoring system with alternative commercial measuring equipment, the research looked at their properties. The proposal includes a circuit diagram for a monitoring system as well as an electrical circuit to measure current-voltage characteristics.

Measurement of Heart Size in the New Zealand White Rabbit by Cardiothoracic Ratio | Chapter 7 | New Ideas Concerning Science and Technology Vol. 13

 Aim: In small animal practise, radiographic assessment of the heart and other thoracic structures is critical for staging a patient with a suspected cardiac abnormality, deciding on therapy protocols, and monitoring disease progression or response to treatment. For objective assessment of heart size, a variety of procedures and measurement techniques have been developed. The goal of this study was to provide a value for radiographic heart size assessment in the New Zealand White (NZW) rabbit using the cardiothoracic ratio (CTR). The heart size of rabbits was measured using dorsoventral projections. Materials and Methods: The study involved ten healthy NZW rabbits. In each of the animals, a dorsoventral (DV) thoracic radiograph was taken. The 10 rabbits' cardiac and thoracic diameters were measured in radiographs to establish a CTR reference value in normal NZW rabbits.

CTR was 0.54 0.01 with a mean plus or minus standard error of mean (MSEM). CTR values for males (0.54 0.01) and females (0.54 0.01) did not differ significantly (p0.05). There was no link between gender and CTR.

Conclusion: In clinical practise, using CTR to examine the heart radiographically is both objective and simple.

Water Vapor Sensors Based on the Swelling of Relief Gelatin Gratings: Recent Advances and Development | Chapter 5 | New Approaches in Engineering Research Vol. 4

 We present a novel device for measuring relative humidity. Different materials are used in the measurement of relative humidity. The sensor is built around gelatin surface diffraction gratings. This material expands and contracts in response to the amount of water vapor in the air. Diffracted orders appear when a light beam is directed at a grating. First order intensity varies with relative humidity due to gelatin swelling or shrinking. Calibration curves for intensity versus relative humidity have been discovered. The process of making diffraction gratings and testing prototype sensing devices is described.

Illustrating an Efficient 3-D Ray Tracing Method for Prediction of Indoor Radio Propagation at 28 GHz in 5G Network | Chapter 1 | New Insights into Physical Science Vol. 9

 The fifth generation networks would be dominated by millimetre wave technology due to the obvious The benefit of higher frequency and thus broader spectrum bands. The Indoor Radio Wave in this article The 28 GHz propagation is studied by the development of effective three-dimensional ray tracing (ETRT) Process. The ETRT model based simulation programme has been tested by measurement results. Important agreement between simulation and measurement has been shown by the obtained signal strength indication and path loss. The proposed ETRT method has greater agreement with measurement data compared with the traditional shooting bouncing ray tracing method. Appropriate agreement on the proposed approach is reached on the basis of a detailed comparison. Further research into the 28 GHz mmWave indoor mobile network networks is expected to direct the results of this research.
