As renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. This paper presents unit commitment (UC) which takes into account the volatility of wind power generation. The UC problem is solved with the forecasted intermittent wind pow...

This paper presents the design and fabrication of a novel piezoelectric actuator for a gas micro pump with check valve having the advantages of miniature size, light weight and low power consumption. The micro pump is designed to have eight major components, namely a stainless steel upper cover layer, a piezoelectric actuator, a stainless steel diaphragm, a PDMS chamber layer, two stainless ste...

227 Lymphoedema is a chronic, debilitating disorder resulting from congenital abnormality of the lymphatic system (primary lymphoedema) or acquired causes (secondary lymphoedema). Complex decongestive physiotherapy is the ‘mainstay’ intervention for lymphatic insufficiency comprising manual lymph drainage, in selected cases intermittent pneumatic compression, multilayered compression bandaging ...

Two cases of frontal, space occupying tumour without papilloedema are reported. Both presented with frequent, stereotyped attacks of visual disturbance with orbital headache, neck pain and unsteadiness of gait. Intermittent occipital lobe ischaemia, related to compression of the posterior cerebral artery against the tentorium by distorted, herniating brain, seems a probable explanation.

Continuous glucose monitors (CGMs) measure interstitial fluid (ISF) glucose, and provide information about continuous glucose fluctuations that is not otherwise captured by intermittent blood glucose testing. CGMs may benefit patients having difficulty controlling their blood sugar or during initiation or monitoring of insulin pump use. CGMs require calibration with finger-stick tests and suppl...

Popliteal artery entrapment syndrome is a rare cause of peripheral vascular disease, often affecting young adults. Multiple studies have shown that osteochondromas can cause vascular injury. Intermittent compression, pseudoaneurysm, thrombosis, distal embolism, and venous thrombosis have all been described as possible complications. Here we present a case of popliteal arterial entrapment type I...
