BACKGROUND Intraoperative awareness (IA) is diagnosed when patients can recall their surroundings or an event related to the surgery that occurred while they were under general anaesthesia. The female gender and Caesarean section are considered to be contributing factors. The aim of the present study was to analyse the frequency of IA in patients undergoing general anaesthesia either for Caesar...

Thermal characteristic is one of the key performances dry-type on-board traction transformer (D-OBTT), which directly affects operation safety new generation electric multiple units. However, due to particularity train-induced wind cooling mode D-OBTT, existing efficient thermal modelling methods cannot be used under fluctuating air velocity and load. A time-saving transient model for D-OBTT pr...

this article aims at strategic vision to technology and suggests a strategic planning for this purpose. the main emphasis in this article is on strategic report compilation in the framework of strategic vision and covers issues such as identification of strategic planning dimensions and strategic vision levels, technology priority setting, environment monitoring, focus on costumer needs, method...

Paleolatitude evolution could provide a general paleo-location framework for explaining the paleoclimate change and tectonic deformation in geological time. Strengthening paleolatitude study of Tuotuohe Basin is important understanding history mechanism uplift process north-central Tibetan Plateau. In this study, we introduced magnetostratigraphy Tuotuohe-D (TTH-D) section Basin, central-northe...

Discrete-time dynamic programming. This section achieves two goals at once. One is to demonstrate the utility of discrete-time dynamic programming as a flexible tool for decision-making in the presence of uncertainty. The second is to introduce some financiallyrelevant applications. To achieve these goals Section 7 presents three examples: (1) optimal control of execution costs (following a pap...

In this paper we provide a numerical analysis of the M D N queueing system This system consists of an in nite bu er and N identical batch servers with batch capacity b It serves as a model for various types of workstations in the manufacturing context Using an approach presented by Crommelin we derive the distribution of the number of lots waiting in queue at arbitrary time instants and the dis...

In this paper the optimal control of boundary heat flux in a 2-D solid body with an arbitrary shape is performed in order to achieve the desired temperature distribution at a given time interval. The boundary of the body is subdivided into a number of components. On each component a time-dependent heat flux is applied which is independent of the others. Since the thermophysical properties are t...
