Example An operating system is a widely-used example of a complex concurrent system that manages many different types of applications and hardware. For instance, it coordinates and demultiplexes the communication between standard Internet networking applications, such as telnet, ftp, smtp, dns, and inetd, and hardware I/O devices, such as network interfaces, disk controllers, end-user terminals...

background: it is important to learn how to study for different examinations. the objective of the current study is to explore whether the assessment method selection would significantly affect the studying and learning approaches of students. methods: this descriptive-analytical research consisted of 191 first-year undergraduate nursing students from three nursing schools and was conducted dur...

Reinforced Concrete (RC) deep beams are commonly used in structural design to transfer vertical loads when there is a vertical discontinuity in the load path. Due to their deep geometry, the force distribution within the RC deep beams is very different than the RC shallow beams. There are some strut and tie model (STM) already been developed for RC deep beams. However, most of these models are ...

Relation extraction models based on deep learning have been attracting a lot of attention recently. Little research is carried out to reduce their need of labeled training data. In this work, we propose an unsupervised pre-training method based on the sequence-to-sequence model for deep relation extraction models. The pre-trained models need only half or even less training data to achieve equiv...

streptokinase is a potent fibrinolytic agent which is widely used in treatment of deep vein thrombosis (dvt), pulmonary embolism (pe) and acute myocardial infarction (mi). major limitation of this enzyme is its short biological half-life in the blood stream. our previous report showed that complexing streptokinase with chitosan could be a solution to overcome this limitation. the aim of this re...

Abstract The redistribution of matter in the deep-sea depends on water-flow currents and turbulent exchange, for which breaking internal waves are an important source. As turbulence essentially three-dimensional ‘3D’, their dynamical development should ideally be studied a volume seawater. However, this is seldom done ocean where 1D-observations along single vertical line already difficult. We ...
