Wireless sensor networks have many applications in the real world and have been developed in various environments. But the limitations of these networks, including the limitations on the energy and processing power of the sensors, have posed many challenges to researchers. One of the major challenges is the security of these networks, and in particular the issue of authentication in the wireles...

Abstract: The development of distributed generation (DGs) units in recent years have created challenges in the operation of power grids, especially distribution networks. One of these issues is the optimal allocation (location and capacity) of these units in distribution networks. In this thesis, a method based on the improved ant colony optimization algorithm is presented to solve the problem ...

Short-term maintenance of verbal information is a core factor of language repetition, especially when reproducing multiple or unfamiliar stimuli. Many models of language processing locate the verbal short-term maintenance function in the left posterior superior temporo-parietal area and its connections with the inferior frontal gyrus. However, research in the field of short-term memory has impl...

Ecosystem of arid and semiarid regions of the world, much of the country lies in the sensitive and fragile environment Canvases are that factors in the extinction and destruction are easily destroyed in this paper, artificial neural networks (ANNs) are introduced to obtain improved regional low-flow estimates at ungauged sites. A multilayer perceptron (MLP) network is used to identify the funct...

Drives and motivations assist in natural action selection through temporarily focusing an agent’s behavioural attention on particular problems, thus escaping problems of dithering between goals. In artificial systems and models, durativestate-based mechanisms for action selection like emotions and drives have sometimes been neglected altogether in favour of planned or reactive control, or somet...

Characterization of quantum objects, being them states, processes, or measurements, complemented by previous knowledge about is a valuable approach, especially as it leads to routine procedures for real-life components. To this end, Machine Learning algorithms have demonstrated successfully operate in presence noise, estimating specific physical parameters. Here we show that neural network (NN)...

Roller is a key component of milling machine in iron and steel industry, with the development of industrial wireless technology. The online predictive maintenance of the roller plays an important role in effective production. But the harsh working environment – spray of cooling liquid, moving, high temperature and heavy shelter – cause low quality of wireless communication and need high reliabi...

Sensor network deployment and its maintenance are very challenging due to hostile and unpredictable nature of environments. The field coverage of a wireless sensor network (WSN) can be enhanced and consequently network lifetime can be prolonged by optimizing the sensor deployment with a finite number of sensors. In this paper, we propose an energy-efficient fuzzy optimization algorithm (EFOA) f...
