Flowmetering terms can often seem cryptic. Here are definitions of some of the most commonly used. ACCURACY Accuracy is a quantity defining the limit that errors will not exceed. This value should include the combined effects of conformity, hysteresis, deadband, and repeatability errors. When applied to flowmeters, accuracy is specified in one of two different ways; % of full scale or % of rate...

The remaining useful life (RUL) prediction of Lithium-ion batteries is closely related to the capacity degeneration trajectories. Due to the self-charging and the capacity regeneration, the trajectories have the property of multimodality. Traditional prediction models such as the support vector machines (SVM) or the Gaussian Process regression (GPR) cannot accurately characterize this multimoda...

The subthalamic nucleus (STN) currently is considered to play a key role in the pathophysiological origin of the parkinsonian state and is therefore the main target for surgical treatment of Parkinson's disease. The authors review the incidence of hemichorea/ballism (HCB) as a complication of thalamotomy, pallidotomy or campotomy procedures before the introduction of levodopa therapy, including...

The method of robust design has long been used for the design of systems that are insensitive to noises. In this paper it is demonstrated how this approach can be used to obtain a robust eco-design (ecological design). In a case study, robust design principles are applied to the design of a factory smokestack, using the Gaussian Plume Model (GPM). The GPM is a well-known model for describing po...

A complete understanding of the Earth’s hydrologic cycle necessarily dictates an ability to accurately quantify the global range of precipitation rates and types (rain, snow etc.). In turn, global observations of precipitation are most efficiently made from space. Great strides in the measurement of global tropical rainfall have occurred recently as a result of the NASA Tropical Rainfall Measur...

This study was carried out to investigate an effective method for the co-delivery of Gemcitabine (GEM) and paclitaxel (PTX) into tumor cells. GEM and PTX were modified with functional (+)-a-tocopherol (VE) to obtain similar water solubility. Folic acid-poly(ethylene glycol)–(+)-a-tocopherol (FA–PEG–VE) was designed to co-encapsulate the modified GEM and PTX. Methoxy poly(ethylene glycol)–poly(l...

Numerous studies conducted as part of the Tropical Rainfall Measurement Mission (TRMM) program have demonstrated the benefits of space-borne precipitation measurements. The NASA Global Precipitation Mission (GPM) is an outgrowth of TRMM that will provide improved precipitation measurements and extend those measurements to higher latitudes. GPM satellite will carry a microwave imager coupled wit...

Since the early 1980s, CAPP has been expected to bridge the gap between CAD and CAM. Though numerous research works on CAPP have been reported, it is not easy to ®nd a commercial CAPP system applicable to complicated objects with freeform shapes such as mold and die. The dependency on CAM system is holding one leg of CAPP, while the complexity of the solution space in freeform shape machining h...
