In this paper, a sensorless speed control for linear induction motors (LIMs) is developed based on fuzzy observer design. First, the LIMs is represented by a Takagi-Sugeno (T-S) fuzzy model. Next, the fuzzy observer is constructed to estimate the immeasurable states of mover speed and secondary flux, where the observer gains are obtained by solving a set of linear matrix inequalities (LMIs). To...

Since the introduction of vaccines, the impact of vaccinations has been immeasurable. Under the current immunization guidelines, infants receive the first of their routine infant vaccinations at 2 months of age. While the benefits of routine infant vaccinations in premature infants have been demonstrated, there is relatively little data on the dosing of these vaccines in premature infants. The ...

Concept and establishment of essential amino acids in animals and human beings rendered immeasurable contributions to animal production and human health. In ruminant animals, however, essential amino acids have never been completely established. The present review proposes a hypothesis that histidine may not be an essential amino acid for normal growing cattle (Japanese black) at least at the g...

The successful revision and camouflage of facial scars is as much an art as a science, and the best teacher is continued experience; however, common sense, a broad knowledge of available options, technical ability, and patience are all necessary if one chooses to practice in this challenging field. Patients with facial scars are vulnerable in a way that few others are, and it is the responsibil...

The phenomenal increase of online video content confronts the consuming user with an immeasurable amount of data which can only be accessed with sophisticated multimedia search and management technologies. Usual video search engines provide a keyword-based search, where lexical ambiguity of natural language often leads to imprecise and incomplete results. Semantics of keywords and metadata has ...

Vehicle active safety control is attracting ever increasing attention in the attempt to improve the stability and the maneuverability of electric vehicles. In this paper, a neural network combined inverse (NNCI) controller is proposed, incorporating the merits of left-inversion and right-inversion. As the left-inversion soft-sensor can estimate the sideslip angle, while the right-inversion is u...

A new quadratic digital tracker for efficient tracking control of an unknown sampled-data system with a direct transmission term from an input to output and subject to input constraints is proposed in this paper. First, the observer/Kalman filter identification (OKID) method is utilized to identify an appropriate (low-) order state-space innovation model with a feed-through term, equivalent to ...

background road traffic injuries (rtis) impose a significant social and economic burden. objectives the objective of this study was to estimate the medical costs and economic burden caused by rti in iran methods the major components included in this study were medical costs, lost output, and indirect costs. cost components and their values in 2011 were obtained using previous data collected dur...

In this chapter we look at the strategic issue facing firms regarding whether or not to remanufacture their used products. We identify some direct costs of remanufacturing as well as some opportunity costs that should be included in a firm’s decision to remanufacture or support the secondary market of remanufactured products. We also explore how this decision may change under different competit...
