The use of capacitors in power systems has many well-known benefits that include improvement the system factor, voltage profile, increasing maximum flow through cables and transformers reduction losses due to compensation reactive component flow. By decreasing cables, systems' loads can be increased without adding any new or overloading existing cables. These depend greatly on how are placed system. In this paper, problem optimally determine locations install sizes installed buses radial...

The patency of saphenous vein grafts is poor compared with native and arterial bypass grafts. Graft failures are often managed percutaneous coronary intervention (PCI) because the higher risks undergoing redo artery graft surgery. In addition, PCI to has a high incidence stent failure but still sometimes required, especially in refractory angina similar our case. We demonstrate safety feasibility use intravascular lithotripsy as an adjunct for severe calcified in-stent restenosis graft. Our...

Network security field had gained research community attention in the last decade due to its growing importance. This paper addresses directly one vital problem that is “Intrusion Detection System” (IDS). As much as many researchers tackle this problem, challenges arise while converting reliable automatic system. The biggest challenge make system works with low false alarm new unseen threats. In paper, we address by building a descriptive model using different models of deep Recurrent Neural...

In this paper, the firefly algorithm with a modified parameterless penalty function is used to determine optimal settings of Flexible AC Transmission System (FACTS) devices including Thyristor controlled phase shifting transformer TCPST, series capacitor (TCSC) and Static VAR Compensator (SVC). Use FACTS in power system reduces active losses improves voltage profile. The proposed solves an flow (OPF) problem for without as initial step generators' voltages powers calculate losses. locations...

Human error is considered one of the major causes car accidents. One potential approach to reduce human driving errors continuously monitor driver's performance while driving. This could help in detecting risks and thus likelihood In this paper, we introduce a machine learning system that analyzes brain activity predict performance. While driving, monitors mental state by analyzing acquired Electroencephalography (EEG) signals. Additionally, proposed acquires EEG from driver before predicts...

Background: Lower face and neck lift may be easilynoticed by most plastic surgeons as well other individuals,by spotting some peculiar landmarks. Besides obvious postoperativescars or major post-operative complications,ear synkinesis, also called "operated look ear", "stuck on","pulled" "pixie" ear, is among the prominent features [1].Treating ear synkinesis challenging unsatisfactoryfor both patients surgeons. It would ratheravoidable than correctable [2].The reported technique a simple...

Axial-flow ventricular assist devices are being increasingly used to support hemodynamically compromised patients undergoing percutaneous coronary intervention. Periprocedural valvular complications have been recognized in a few case reports. We present unique of entanglement the Impella within he mitral subvalvular apparatus, retrieved successfully using snare under fluoroscopic guidance. (Level Difficulty: Advanced.).

Introduction: Lipoinjection can be used to give extra-volume during breast enhancement surgeries and coect various types of depressed deformities the breast, but certain problems remain as unpredictability low graft survival which are a major concern in plastic surgery. Different trials techniques were done for enhancement take vascularity fat grafting. Platelet Rich plasma plays an important role process vascularization  grafted  fat  due  to  its  high  content  of  Platelet Derived...
