This work develops a compact 9 GHz microwave imaging system. The core of the system is a vector network analyzer (VNA) which utilizes range-correlation architecture to suppress the phase noise of the received signal. To overcome the bottleneck that conventional mixer-based phase detectors have limited phase detection range, a novel quadrature phase detection algorithm is proposed. The experimental results show that the microwave imaging system can well detect the bone image of a chicken wing. © 2018 IEEE.

There is a necessity to schedule the system and user processes by the operating system to getting maximum utilization of the CPU and obtaining high throughput. This paper presents a dynamic scheduling algorithm that make use of genetic algorithm operations for scheduling multi non-preemptive task on uniprocessor system to get minimum average waiting time and average turnaround time. The algorithm dep.nd on construct fitness function that take in its consideration the dead time of process to avoid the starvation problem, in addition to obtaining maximum throughput. The results from proposed algorithm simulation by matlab (8.3) illustrates the successful of this method to obtain optimal result by giving the minimum average turnaround time for executing the given processes. © 2017 IEEE.

For several economical, financial and operational reasons, forecasting energy demand becomes a key instrument in energy system management. This paper develops a natural gas forecasting approach, which consists of two major phases: 1) it classifies the natural gas consumption daily pattern sequences into different groups with similar attributes. 2) the design and training of multiple autoregressive Gaussian Process models phase is carried out using the Algerian natural gas market data together with exogenous inputs consisting in weather (temperature) and calendar (day of the week, hour indicator) factors. The main novelty in this work consists of the investigation of multiple different clustering techniques for better analysis and clustering of natural gas consumption data. The impact of the obtained clusters, by each technique, is then summarized and evaluated with respect to the prediction accuracy.

Lightning-induced surges can cause backflashovers in transmission lines which lead to outages in power systems. In this context, the tower-footing grounding impedance and tower surge impedance play fundamental roles in reducing the lightning-induced surges. The tower footing grounding impedance and tower surge impedance have been evaluated by many models and numerical methods in the frequency and the time domain. The tower-footing grounding system is represented by lumped or distributed parameter models and the tower surge impedance is calculated by geometric solid models or lumped circuits. In this article, the full-wave solution of Maxwell's equations using the method of moments is used for calculating the tower-footing grounding impedance of counterpoise electrodes in the frequency domain for various values of soil resistivity. Then, the admittance of two different transmission towers is calculated for various soils by the same method. Once the admittance of the combined tower and the footing is obtained, a lumped circuit model is developed that will enable the lightning-induced surge calculation directly in time domain. © 2018 IEEE.

The recently created IETF 6TiSCH working group combines the high reliability and low-energy consumption of IEEE 802. 15.4e Time Slotted Channel Hopping with IPv6 for industrial Internet of Things. We propose a distributed link scheduling algorithm, called Local Voting, for 6TiSCH networks that adapts the schedule to the network conditions. The algorithm tries to equalize the link load (defined as the ratio of the queue length over the number of allocated cells) through cell reallocation. Local Voting calculates the number of cells to be added or released by the 6TiSCH Operation Sublayer 6top. Compared to a representative algorithm from the literature, Local Voting provides simultaneously high reliability and low end-to-end latency while consuming significantly less energy. Its performance has been examined and compared to On-the- fly algorithm in 6TiSCH simulator by modeling an industrial environment with 50 sensors. © 2018 IEEE.

In this study, a cooperative control problem with obstacle avoidance for a team mobile agent system is investigated. The agents are modelled with double integrator dynamics considering the center coordinates in 2D space. The underlying topology of the focused system is captured by an undirected graph. Firstly, basic consensus controller structures are explained. Then obstacle avoidance problem which is based on collision cone approach is examined. Finally, both controller algorithms are combined and simulated with using second-order agent model. Simulation studies have been conducted with MATLAB program. The obstacle is selected a circle stationary object. The results show that the agents use the collision avoidance algorithm to prevent obstacle and consensus algorithm to reach consensus point after passing the obstacle.

Fog Computing is a recent and compelling paradigm that proposes to run information-processing services at the edge of the network. While interesting standardization efforts are being currently pursued by many organizations, most of them focus on management and orchestration functions and primarily propose the adoption of programming models designed for Cloud applications in the Fog. Instead, Fog Computing applications would significantly benefit from innovative solutions that adopt an "acceptable lossiness" perspective and manage information processing and dissemination in a dynamic and integrated fashion. This paper presents an overview of the opportunities and challenges in Fog Computing application development, proposes an innovative holistic Software Defined Networking (SDN) approach based on an information-centric and value-based service model to support those applications, and presents an overview of the Holistic Analytics and Networking (HAN) SDN architecture that we are developing to realize this ambitious vision.

Investigative Study on the Interaction and Applications of Plasma Activated Water(PAW)

IOP Conference Series: Materials Science and engineering 2020年第1期870卷

作者： Zainab T. Al-Sharify Talib A. Al-Sharify baker W. al-Obaidy Ameer M. al-Azawi Env. Eng. Dep. College of Engineering Mustansiriyah University. Baghdad – Iraq Chem.Eng Dep.

Cold plasma is a budding technology that can be used as a nonthermal disinfectant and for surface modification which is free of chemicals and is environmentally friendly. The treatment of water with plasma, producing plasma activated water (PAW), generates an acidic condition resulting in the formation of reactive oxygen species (ROS), reactive nitrogen species (RNS), and creates change in the redox potential as well as conductivity. Consequently, the chemical composition of water and PAW differ from each other and can now be employed as a substitute for disinfection against microbes. The various sources of plasma used for PAW production, its physical and chemical properties and its prospective uses are reviewed in this paper. Particularly, the physiochemical properties of PAW will be discussed in the context of its acidity, conductivity, the amount of ROS and RNS, as well as its redox potential. Since the results are microbial in nature, the microbial disinfection with the use of PAW will also be reviewed. Lastly, the usage of PAW to enhance agricultural methods, such as its effect in plant growth and stimulating seed germination, is also discussed. It can be interpreted that PAW synergistically disinfects food as well as enhances the growth of seedlings. The boost in plant growth conceivably be mainly due to the increase in concentration of nitrate and nitrite ions in PAW. Therefore, in addition to the antimicrobial action of PAW, submerging seedlings in PAW supplements the germination of seeds and plant growth. This could possibly help fight against the drought stress and improve the yield of crops.
