In this paper. we have articulated that as more and more IoT based devices get connected to the Internet. it results in the extension of the surface area for external attacks. We classified those attacks based on the layers that make up IoT and discussed several such attacks with examples. …

Integrated Energy Systems for Multigeneration looks at how measures implemented to limit greenhouse gas emissions must consider smart utilization of available limited resources and employ renewable resources through integrated energy systems and the utilization of waste energy streams. This reference considers the main concepts of thermal and conventional energy systems …

A new single switch high static gain non-isolated dc-dc converter is presented in this paper. The proposed converter topology is suitable for renewable energy based applications having low input dc voltage. The proposed converter provides high voltage conversion without using transformer and coupled inductor. The semiconductor power devices used in …

Practical Wellbore Hydraulics and Hole Cleaning presents a single resource with explanations. equations and descriptions that are important for wellbore hydraulics. including hole cleaning. Involving many moving factors and complex issues. this book provides a systematic and practical summary of solutions. thus helping engineers understand calculations. case studies and guidelines …

Voluminous amounts of data have been produced. since the past decade as the miniaturization of Internet of things (IoT) devices increases. However. such data are not useful without analytic power. Numerous big data. IoT. and analytics solutions have enabled people to obtain valuable insight into large data generated by IoT …

This paper has presented a comprehensive analytical method for designing LCL filter of a three-phase power factor correction rectifier (PFC). The method is explained by the converter current and the voltage behavior. The converter current ripple determines all the filter parameters and defines a suitable margin for them. A general …

The transformer percent differential protection is not reliable enough during external fault. if the differential restraint characteristic is the only one criteria providing security. The saturation of CTs during external faults could lead to cases of dangerously high differential restraint ratios crossing the characteristic into the operating region and causing …

To realize the wideband DPA above 3GHz. the frequency dependency compensating circuit and the λ ۴ inverter incorporating parasitic elements inside package were proposed. The feasibility of the approach was verified by measurement results. and it achieved 45.9- 50.2 % drain efficiency with -50 dBc ACLR over the 3.0- 3.6 …

In this paper. a novel MS-LMFM motor has been proposed and several varied geometric parameters have been optimized for maximum thrust force. Furthermore. a comparison between the proposed and existing motor has been carried out under fixed copper loss by FE method. Compared with the existing motor. it is confirmed …

The feasibility and performance of a battery charger for PHEV application using back to back (B2B) converter in a utility connected micro-grid has been investigated in this paper. A structure has been proposed involving three parts: an AC micro-grid. in which the load is fed from the DG source. a …
