Modern photovoltaic (PV) systems have received significant attention regarding fault detection and diagnosis (FDD) for enhancing their operation by boosting dependability, availability, necessary safety. As a result, the problem of FDD in grid-connected PV (GCPV) is discussed this work. Tools feature extraction selection classification are applied developed approach to monitor GCPV system under...

The high pressure neurological syndrome develops during deep-diving (>1.1 MPa) involving impairment of cognitive functions, alteration of synaptic transmission and increased excitability in cortico-hippocampal areas. The medial perforant path (MPP), connecting entorhinal cortex with the hippocampal formation, displays synaptic frequency-dependent-depression (FDD) under normal conditions. Synapt...

BACKGROUND Flow-dependent, endothelium-mediated vasodilation (FDD) and activity of extracellular superoxide dismutase (EC-SOD), the major antioxidative enzyme of the arterial wall, are severely impaired in patients with coronary artery disease (CAD). We hypothesized that both ACE inhibitor (ACEI) and angiotensin II type 1 receptor antagonist (AT(1)-A) increase bioavailability of nitric oxide (N...

BACKGROUND Endothelial dysfunction of coronary and peripheral arteries has been demonstrated in patients with chronic heart failure (CHF) and appears to be associated with functional implications. However, it is unknown whether endothelial dysfunction in CHF is independently associated with impaired outcome or progression of the disease. METHODS AND RESULTS We assessed the follow-up of 67 con...

Massive MIMO systems that for a cellular network, the channel from user equipment to a base station is composed of few grouped paths in space. With a very large antenna array, signals can be observed under extremely sharp regions in space. In the FDD mode, each BS sends a downlink training matrix to its served UEs which estimates the desired channel based on the downlink measurements and feeds ...

BACKGROUND Chronic heart failure (CHF) is associated with endothelial dysfunction including impaired endothelium-mediated, flow-dependent dilation (FDD). There is evidence for increased radical formation in CHF, raising the possibility that nitric oxide is inactivated by radicals, thereby impairing endothelial function. To test this hypothesis, we determined the effect of the antioxidant vitami...

Unified RF requirements are derived for an UTRA/FDD com-pliant mobile transceiver. Consideration of system issues,multi-mode operation, and interfacing concerns leads to de-tailed receiver and transmitter calculations based on exist-ing UMTS specifications. Finally, compliant and design-compatible transceiver requirements are derived.KeywordsRF Transceiver, UTRA/...

This paper presents a feasibility study of DC offset filtering for direct-conversion UTRA-FDD/WCDMA receivers. Spectral characteristics and properties of continuous transmission facilitate the use of simple high-pass filtering and this method is evaluated in the paper. Design equations for DC offset power to down-converted signal power ratio are presented and the impact on bit error rate of hig...

Formal methods are crucial in program specification and verification. Instead of building cases to test functionalities, formal specify functionalities as properties mathematically prove them. Nevertheless, the applicability is limited most development processes due requirement mathematical knowledge for developers. To promote application methods, we formulate formalism-driven (FDD), which an i...
