The electric power systems are interconnected for the economical and reliable operation of supply systems. An interconnection can be implemented through AC DC links. A variable frequency transformer (VFT) has emerged as an alternative asynchronous interconnection, like back-to-back HVDC Unlike links, VFT requires reduced reactive power, offers quicker incipient transient recovery, coherent damp...

Electronic Health Records (EHR) serve as a solid documentation of health transactions and vital resource information for healthcare stakeholders. EHR integrity security issues, however, continue to be intractable. Blockchain-based architectures, address the issues very effectively. In this work, we suggest decentralized patient-centered data management (PCHDM) with blockchain-based framework co...

introduction: nowadays, without utilization of information technology, it is impossible to have effective access to required information. inappropriate use of new technology for professional knowledge transmission leads to inadequacy of technology as well as cost wasting. therefore, it is necessary to enhance general understandings about information technology (it) abilities and also end-user n...

The magneto-rheological fluid Dual Clutch Transmission (MDCT for short) adopts the magneto-rheological (MR for short) effect of magneto-rheological fluid (MRF for short) and the working characters of Dual-Clutch Transmission (DCT for short), and combines the characteristics with long service life, no wear, simple structure, accurate control of MR effect with the principles of DCT technology, it...

Four or more streams of MIMO transmission are needed to achieve data rates in excess of 1 Gbps in LTE-Advanced systems. However, accommodating more antennas for four or more streams of MIMO transmission means that a rise in costs and the difficulty of securing the space for additional antennas must be dealt with. This article describes NTT DOCOMO’s new transmission technology, Smart Vertical MI...

Multiple-input multiple-output (MIMO) transmission is attracting interest for increasing the transmission rates of wireless systems. This paper surveys MIMO transmission technology from the viewpoints of transmission methods, access control schemes, and total transmission efficiency. We consider wireless local area networks (WLAN) systems that use MIMO technology; moreover, we focus on multiuse...
