Published: July 2020

Abstract
A significant solution to achieve energy efficiencies and stability of the electrical network is upgrading auto-consumption in a single PV system. In this paper, we presented a methodology to implement low-cost sensors and actuators to have better monitoring and control for a feasibility solution. This approach has been conducted through a case study on Greenhouse’s PV system in Grenoble, France. We proposed a minimal set of sensors to reduce system complexity while giving us enough information to make decisions. Some technical issues were analyzed as accuracy, sampling rate, response-ability of our system. The influences of inverter operation mode to system losses were considered. After that, we figured out energy problematics in our system based on available design data and simulation data from PVSyst. A PV production prediction model was investigated with input as forecast cloudiness data collected from web service, updated every 3 hours. This model, combined with real-time monitoring data and setting mode on an off-grid inverter, was used to identify control strategies with objectives of avoiding oversize storage capacity and maximizing the autonomous duration of the PV system.

Abstract
As cities in Vietnam, a combined drainage system has been building in Danang City. In recent years, Danang City has been extensively developing. However, additional wastewater treatment plants have not been built. As a result, wastewater and rainwater are discharged directly into the coastal areas. The initial period of the runoff after first rainfall events can be called the first flush, which has higher pollutants. So the contribution of pollutants from the first flush must be considered in order to correctly make an environmental preservation method for the coastal area. This study uses Mike Urban with modelling water quality to analysis the sensitivity of the NH4
+ concentration in the first flush of the areas. In addition, rainfall intensity and Antecedent Dry Weather Period are two key factors influencing the pollutants of the first flush. Through the results of the simulation, the NH4
+ concentration increase follows the rainfall intensity with maximum concentration appearing when rainfall intensity reaches 19 mm/h. However, NH4
+ concentration then decreases even when rainfall intensity increases. NH4
+ concentration reaches up to around 15 mg/l every 5 days dry period with 30 mm/h rainfall intensity.

Authors: Mohammed Yaseen A , Abbas Hatem H 
Published: July 2020

Abstract
Achieving high data rate communications and increasing system reliability are the essentials for 5G networks. Massive MIMO and millimeter wave (mmWave) communications along with the ongoing developments in the underlying infrastructure promise to sharply increase the aggregate capacity. The communication system harnessing the odds of the unused spectrum in mmWave bands is vulnerable to the extreme path loss that severely weakens the strength of the information-bearing signal. Nevertheless, exploiting hybrid beamforming and efficient high-speed channel estimation algorithm can help address this problem and create the communication systems required for 5G. Our main contribution in this paper is to propose a very high speed accurate greedy algorithm called Subspace Pursuit (SP) and we also compare the performance of this algorithm with two other greedy algorithms. Simulation results show that SP algorithm achieves a noticeable improvement in comparison with Orthogonal Matching Pursuit (OMP) and Regularized Orthogonal Matching Pursuit (ROMP) algorithms in terms of both the spectral efficiency and runtime.

Abstract
The importance of disaster management systems is undeniable and is unable to be underestimated because of the numerous manmade and natural disasters now days like theearthquake in Japan, the tsunami disaster in 2011 and the Hurricane Sandy in 2012. The Japan disaster estimated cost was more than 300 billion US dollar. The role of telecommunications and transport is an indispensable resource to manage disaster in averting the human life loss, economic cost and in controlling the disruption. Focusing on the emergency transporting systems, an emergency response system was proposed for disasters at various levels of scale. The system exploits the Information and Communication Technology (ICT) developments, in addition developing a new tool/model to assess the suggested intelligent disaster system within the transportation evacuation strategies performance. The Speed Strategy (SS) and Demand Strategy (DS) were evaluated separately and simultaneously, for traffic in urban networks. In this work the intelligent disaster system Intelligent which utilizes the Intelligent Transportation Systems (ITS) were employed. In other words, varied substitute technologies which includes VANETs (Vehicular Ad hoc Networks) and mobile technologies are applied to suggest and examine an evacuation strategy called (Destination Strategy) while using the proposed Intelligent Disaster Management System. The effectiveness of the current developed system was observed by comparing the modelled consequences of a disaster on the transport environment with that of when the disaster management was implemented. Moreover, a balance and improvement in the traffic flow with effortless evacuation was observed as an outcome of the developed current work along with the implemented Designation Strategy.

Published: July 2020

AbstractPlastic waste management has become a burden and a threat for countries and major cities as well as a danger to environmental safety. The current report covers the ability of the concrete sector to use and recycle plastic wastes. The demand for concrete and raw materials for construction engineering has become very high in recent years because of urban development and the expansion of cities. Therefore, the use of this waste in civil and structural engineering is considered a successful way to get rid of plastic wastes properly to protect the environment. This research investigates the effectiveness of using plastic drinking water bottles (currently the highest plastic waste on the Iraqi market) as a partial substitution of the gravel in concrete. Plastic waste was added in different weight ratios of 2.5%, 5% and 10% as a partial substitute for the gravel and a cement mixture. A benchmark of 0% plastic wastes was prepared as a reference concrete for comparison purposes. The results show the possibility of using plastic waste, such as construction material. The results show a decrease in concrete strength by 12%, 29%, and 47%, and a reduction in concrete density by 10%, 16% and 31%, respectively. Research results show that this is useful to add plastic wastes for obtaining lightweight concrete.

Authors: Al-Sharify Zainab T. , Al-Sharify Talib A. , al-Obaidy baker W. , al-Azawi Ameer M. 
Published: July 2020

Abstract
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.
