State feedback controllers can be used to restore predictable behavior of asynchronous sequential machines that are afflicted by a critical race. The present note presents necessary and sufficient conditions for the existence of such controllers. The controllers also assign a specified behavior to the controlled machine. Copyright ©IFAC 2002

purpose the aims of the present study were to investigate (i) the changes in participation and performance and (ii) the gender difference in triple iron ultra-triathlon (11.4 km swimming, 540 km cycling and 126.6 km running) across years from 1988 to 2011. methods for the cross-sectional data analysis, the association between with overall race times and split times was investigated using simple...

purpose the aim of this study was to evaluate predictor variables of race time in female ultra-endurance inliners in the longest inline race in europe. methods we investigated the association between anthropometric and training characteristics and race time for 16 female ultra-endurance inline skaters, at the longest inline marathon in europe, the ‘inline one-eleven’ over 111 km in switzerland,...

abstract:   background: the most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. the differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. the a...

conclusions the tmd, with a cut-off point of 65 mm, had superior diagnostic value compared with the hmdr and mallampati score. therefore, the tmd could be used in malay patients to predict the difficulty of larynx visualization during laryngoscopy. results difficulty in visualizing the larynx was found in 28 (10.1%) patients. the auc, sensitivity, and specificity for the three airway predictors...

introduction: to compare the cleaning effectiveness of k3 and race niti rotary systems with k-flexo file instruments during the preparation of curved canals in extracted human teeth. materials and methods: a total of 50 root canals of mandibular and maxillary molars with curvatures ranging between 25º and 35 º were divided in three groups of 15 each and 5 as negative control groups. canals were...

This study investigated the differential predictive validity of the Developing Cognitive Abilities Test (DCAT) in a heterogeneous sample of 863 sixth-grade students. Bias was assessed across gender, race/ethnicity, and socioeconomic dimensions. Level H of the DCAT was administered during the students’ sixth-grade year, and selected subtests from the Iowa Tests of Basic Skills (ITBS) were admini...

This paper develops a two-sector, general equilibrium, overlapping generations model to derive necessary and su cient conditions for the existence of private tutoring in the presence of publicly-provided education. Young agents have heterogeneous endowments of human capital, which can be augmented by mandatory public education and elective private tutoring. Old agents work in the production sec...
