In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. Although rapid technological development created new medical imagin...

The influence of voltage and current harmonics on equipment connected to electrical supply systems can cause serious problems. This paper presents a synopsis of the problem. The equipment most sensitive to harmonics is considered, such as -asynchronous motors, synchronous machines, transformers, capacitors, ripple control receivers, electricity meters, radio receivers, TV-sets, electronic contr...

evaluation of mechanical and electrical properties of agricultural products plays an important role in equipment design and optimizing post-harvest operations. among the crops, tomato and its products are the major processing industries in the world and its economic importance is increasing. considering the importance of the quality and various post harvesting uses of tomato, the evaluation of ...

Current failure analysis practices use diagnostic technology developed over the past 100 years of designing and manufacturing electrical and mechanical equipment to identify root cause of equipment failure requiring expertise with the equipment under analysis. If the equipment that failed had telemetry embedded, prognostic algorithms can be used to identify the deterministic behavior in complet...

During the ageing of in-service medium voltage equipment, electrical losses are mainly due to partial discharges. These partial discharges can lead to the electrical failure of industrial equipment [1]. Partial discharges include (i) bulk discharges occurring in insulating material voids, (ii) corona discharges affecting or not the insulator and (iii) surface discharges developing on an insulat...

The principal advantage of optical sensors for medical applications is their intrinsic safety since there is no electrical contact between the patient and the equipment. (An added bonus is that they are also less suspect to electromagnetic interference). This has given rise to a variety of optical techniques to monitor physiological parameters: for example, the technique of Laser Doppler veloci...

We describe a comparative analysis of the power consumption of optical cross-connect (OXC) equipment based on electrical and/or photonic matrix switching, which will be used for future large-capacity optical networks. The switch configurations used for both types of OXCs are also comprehensively discussed. For optical networks that accommodate traffic with a capacity of several Tb/s, the power ...

The aim of the paper is to analyze the impact of long-term thermal stresses of electrical equipment on climate change. There were determined the steady-state overtemperatures and the thermal time constants for three different section size of a copper busbar system incorporated in a low voltage electric cabinet in order to compare the thermal stresses for each case. To see the influence of the l...

At any point in the life of a building, mechanical and electrical equipment – the services infrastructure – may be poorly operated. Equipment may be inadvertently left in operation when not needed: lights and fans running all night or air conditioning in unoccupied spaces. Or equipment may be operated in ignorance of the cost, a problem exacerbated by time-varying electrical rates. Further, as ...
