چکیده

Our goal in this article is togiveanoverview of the broad area of real-time systems. This task daunting because real-time systems are everywhere, and yet no generally accepted definition differentiates real-time systems from non–realtime systems. We will make an attempt at providing a general overview of the differentclasses of real-time systems, scheduling of tasks (or threads) in such systems, design tools and environments for real-time systems, real-time operating systems, and embedded systems. We will conclude our discussions with research challenges that still remain.

Field effect transistor nanobiosensors: State-of-the-art and key challenges as point of care testing devices

The existing health care systems focus on treating diseases rather than preventing them. Patients are generally not tested unless physiological symptoms are appeared. When they do get tested, the results often take several days and can be inconclusive if the disease is at an early stage. In order to facilitate the diagnostics process and make tests more readily available for patients, the conce...

How Operational Parameters and Membrane Characteristics Affect the Performance of Electrodialysis Reversal Desalination Systems: The State of the Art*

Operating parameters and membrane characteristics strongly affect the performance of electrodialysis reversal systems. The most impactful factors are applied voltage, flow rate, temperature, initial feed composition, and ion exchange membrane characteristics; the pH of the feed also has an effect, although to a lesser extent. To determine more precisely how all of these factors impact performan...

Ensemble-based Top-k Recommender System Considering Incomplete Data

Recommender systems have been widely used in e-commerce applications. They are a subclass of information filtering system, used to either predict whether a user will prefer an item (prediction problem) or identify a set of k items that will be user-interest (Top-k recommendation problem). Demanding sufficient ratings to make robust predictions and suggesting qualified recommendations are two si...

Markovian Delay Prediction-Based Control of Networked Systems

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...
