This study presents an application of the recently reported theories of analytic signal space partitioning (ASSP) and symbolic dynamic filtering (SDF) to address degradation monitoring in permanent magnet synchronous motors (PMSM).An (experimentally validated)mathematicalmodel of generic PMSM is chosen to monitor degradation/fault events on a simulation test bed; and the estimated parameter of ...

The article describes a new control method of transistor power bridge converter. It is a new one, because of some original solutions and its difference in comparison to existing methods. It’s irrelevant of load, similar to the “phase shifted” control method. It is easy to realize using ordinary electronic elements. A significant advantage of method is the possibility of permanent output current...

OBJECTIVES To determine the effectiveness of intraoperative facial nerve monitoring (FNM) in preventing immediate and permanent postoperative facial nerve weakness in patients undergoing primary parotidectomy. DATA SOURCES PubMed-NCBI database from 1970 to 2014. REVIEW METHODS A systematic review and meta-analysis of the literature was conducted. Acceptable studies included controlled serie...

OBJECTIVE To evaluate the postoperative complications and to evaluate and stratify thyroglobulin (Tg) response associated with revision surgery for thyroid malignancy. STUDY DESIGN Case series with chart review. SETTINGS Academic, tertiary care center. SUBJECTS AND METHODS All patients with regionally recurrent thyroid carcinoma and who underwent revision thyroid surgery by the senior aut...

Reservoir monitoring improves our understanding of reservoir behaviour and helps achieve more effective reservoirmanagement and prediction of future performancewith obvious economic benefits. It relies on an integrated approach involving both surveillance (well or surface based; seismic, electrical, leakage, flow and deformation measurements, etc.) and modelling. Surface deformation monitoring ...

BACKGROUND Public health policies aim to improve and maintain the health of citizens. Relevant data and indicators are needed for a health policy that is based on factual information. After 14 years of work (1998-2012), the multi-phase action on European Community Health Indicators (ECHI) has created a health monitoring and reporting system. It has generated EU added value by defining the ECHI ...

Natural and artificial barrier systems are the key elements of a final repository site for hazardous waste in geological formations. The concept is to isolate the waste from the biosphere over a long period of time. During that period, groundwater is prohibited to access the waste since contaminated water may endanger people and environment. Hence, permanent monitoring is important to avoid ris...

A test piece is described for monitoring the performance of low-temperature steam-with-formaldehyde sterilizers. Comparative tests have shown it to be more difficult to penetrate than an arterial catheter when exposed to the same sterilizing conditions. It is permanent and simple to use and maintain. The growth or non-growth of bacterial spores, in the convenient form of spore strips, is used t...
