Authors: Qasim Mohammed A , Velkin V I 
Published: December 2020

Abstract
The hybrid integration of small-scale wind and solar energy conversion systems can be used for on- and off-grid applications. This paper investigates a stand-alone off-grid application of a hybrid small-scale wind turbine and photovoltaic (PV) cell microgrid to supply houses in rural Iraq far from the utility grid. Experimental investigations were performed to measure wind speed and solar radiation, as well as the DC voltage in the rectifier section of a small-scale permanent magnet synchronous generator (PMSG) wind turbine and the DC voltage in a PV cell for 24 hours. The results showed that using a small-scale hybrid wind and solar generating system for off-grid applications in Iraq is possible if the components are equipped with proper charge controllers that perform maximum power point tracking (MPPT) during wind speed and solar radiation fluctuations.

Abstract
The known advantages of Reversible gates namely reduced power consumption and low latency found useful in Quantum computing. Its low power consumption and quicker operation makes them to be useful in applications Microprocessors, DSP processors and Quantum computers. Numerous reversible gates have been found in literature. This article focuses the implementation of 4 bit multiplier with the help of reversible logic gates. Array multiplier is chosen for our choice. Toffoli gate is chosen for partial product generation. The accumulation of partial products is carried using three topologies. The first topology uses reversible carry look ahead adder. The second topology uses parity preserving reversible carry look ahead adders. The third topology uses modified parity preserving reversible carry look ahead adders. The energy efficient multiplier’s topology proposed in this article implementation are done using Cadence 180nm technology. Performance evaluation reveals that the proposed reversible gate based multiplier results lesser power consumption and also a quicker one. It results that the proposed topology consumes 52.03% lesser power, topology 2 consumes 63.02% lesser power and topology 3 consumes 63.79% lesser power when compared with an existing reversible multiplier design. As the power consumption is the dominating quantity in VLSI design, the proposed topologies of multiplier design results better performance. The achieved area occupation of the proposed topology 1, topology and topology 3 are also 58.44%, 61.90% and 69.26% lesser respectively when compared with that existing reversible multiplier. Its quicker operation is also achieved by the reduction in propagation delay. Hence the proposed multiplier topologies named as an energy efficient multipliers.

Published: December 2020

Abstract
Field effect transistors (FETs) are widely used in integrated circuits of electronic devices. Mostly silicon-based FETs are used for commercial purposes, but with the recent advancement in organic electronics – organic thin-film transistors (OTFTs) have become trending research topics nowadays. Modeling of organic FETs helps in understanding various electrical characteristics of the device such as on current, threshold voltage, off current, on/off ratio, and so on. Optimization of these factors is needed to enhance the working and overall performance of thin-film transistors. In this paper, the comparative study of the device having bottom-gate with electrode contact on top and bottom of organic semiconductor has been done based on the effects of organic semiconductor's thickness variation, dielectric thickness variation, and dielectric material variation on pentacene based organic transistors.

Abstract
In the twenty-first century, there is a drastic depletion of non-renewable resources and a steady rise in greenhouse gas emission which causes global warming. In this case, it is wise to increase the use of renewable energy instead of non-renewable ones which will reduce the consumption of AC power. Sustainable energy sources like solar and wind are also used to control AC or DC loads, yet the execution is unsteady because of the ecological issues. Hence, it is essential to have a system with various input power sources which could provide power during a power-cut, grid failure and peak demand. It ensures better to maximum energy utilization and also results in a low electricity bill. This paper analyses the battery energy management which is crucial in the lives of the residential consumers by forming a system which can be operated both in grid connected and battery fed modes. To perform switching, it is mandatory to monitor both the input power sources and the loads simultaneously. When the loads are light loads and the charge of the battery is sufficient to drive the load, the loads are driven through the DC source. When the loads are heavy loads or the charge of the battery is less, the consumer cannot rely upon the DC source for driving the load. So, AC source is used to drive the loads. Depending upon the type of load, battery status and grid availability automatic switching takes place between the AC and the DC source.

Abstract
The presence of fiber in the concrete increases the mechanical properties of the concrete considerably. This paper presents the application of Artificial neural network to predict the compressive and impact strength of the concrete with varying percentage of glass fiber along with different combination of chemical admixtures in concrete such as super plasticiser, air entraining agent, accelerators, retarder and water proofing agent. In experimental part of research, the specimens were tested to failure in order to measure the compressive strength and impact strength by drop weight method. The compressive strength and impact strength of the Glass Fiber Reinforced Concrete (GFRC) with different combination of admixtures get increased to 12% and 90% respectively as compared with control specimen. The predicted strength was compared with the experimentally obtained compressive and impact strength of glass fiber reinforced concrete. The strength predicted by ANN is very close to the experimental results with minimal error.

Authors: Nguyen Van-Tu , Vu Ngoc-Quang , Nguyen Xuan-Dai 
Published: December 2020

Abstract
Multi-story buildings are important components of urban infrastructures due to their undeniable advantages. However, their structures are characterized by the mass distributed in height and a great slenderness leading to its earthquake vulnerability. Further, their typical structures designed by the conventional method provide low earthquake resistance. The seismic isolation bearings are considered as an effective solution for the structure located in regions of high and moderate seismic activity. The paper presents the procedure to calculate the isolated building structure located in the moderate seismicity areas such as Vietnam. The bilinear hysteretic model is employed to determine the properties of the isolator through the simplified procedure. Three-dimensional model of a typical 11-story building structure is analyzed to evaluate the effect of the isolator on seismic responses of building. The modal analysis and time history analysis are performed using Etabs V17, with the input record taken according to the earthquake ground motion in Hanoi-Vietnam, calculated by the Vietnamese code. The result shows the high effectiveness of isolator on reducing the seismic effect.

Abstract
PA6 micro composites with different weight percentage of diboron trioxide (B2O3) were fabricated by a twin-screw extruder and analysed for tribological behaviour. The weight percentage of B2O3 were 2, 4, and 8wt% of PA6 matrix. Tribological tests were performed on pin-on-disc apparatus under different loads, sliding distances, and sliding velocities. Results were shown for individual varying parameter as well as with the combination of two and all three varying parameters conditions. Results of the tribological study shows that the PA6 composite with 2wt% diboron trioxide fillers exhibits lowest friction coefficient (COF) and wear rate compare to others and followed by PA6 with 4wt% diboron trioxide filler composite. PA6 with 8wt% diboron trioxide fillers were not found effective in reducing COF and wear rate, infect it increased the COF and wear rate of PA6 and found maximum compare to pure PA6 and PA6 with 2 and 4wt% diboron trioxide fillers.

Abstract
Wind load and Earthquake load play an indispensable role in structural analysis. Many research works carried out on analysis & design of single column structures. Being inspirit from the previous works on effect of earthquake and wind load on single column structure, this paper presents effects of six different plan configurations i.e., Square, Rectangular, Circular, Triangular, Pentagon and Hexagon with same plan area (144 m2). Mono column structure with different plan geometry react adversely in contrast to earthquake and wind loads. Modelling, analysis and design of Multi storey mono column structure is done by using CSI ETABS software. Seismic and wind analysis has been done and maximum values of Storey displacement, Storey drift, Storey shear, overturning moment, Storey stiffness and Time period results are manifest in form of figures. The purpose of this analysis is to determine the most effective and vulnerable shape of structure in prone areas. Storey displacement, storey drift values are minimum in circular shape structure in all seismic zones. Storey shear, overturning moment, storey stiffness is minimum in square shape structure, maximum in triangular shape structure. Time period is maximum for mono column structure with rectangular plan configuration.

Authors: Babahammou Ahmed , Benamar Rhali 
Published: December 2020

Abstract
The linear flexural vibration of a thin isotropic rectangular plate simply supported at the free corner has been investigated by the symplectic superposition method by Rui.Li and al. The purpose of the present study was to establish the efficiency of the Rayleigh-Ritz method (RRM) applied to similar plate problems. Due to its numerical and systematic character, the RRM has many practical advantages compared to the classical laborious analytical approaches and can be extended to investigate the case of geometrically nonlinear vibrations. The trial plate functions used were obtained as products of beam functions with appropriate end conditions in each direction and the point support was modeled by a translational spring with an infinite stiffness. Different cases have been dealt with corresponding to different edge conditions, different aspect ratios, and for several modes. The comparisons made of the solutions obtained with the known solutions of isotropic rectangular plates with one or more point supports show a satisfactory agreement. The nonlinear vibration of various plates with a with point support at one corner have been also examined. The backbone curves based on the SMA have been calculated by Matlab code. The systematic and straightforward method presented can be readily extended to plates with inside point corners.

Published: December 2020

Abstract
FMany of the global cities are fast developing into resource-starved ecosystems, inefficient, unmanageable and unsustainable, owing to rising population and industrialization, adversely affecting the economic growth and quality of life, health and well-being of the communities inhabiting these cities. Furthermore, because of increasing urbanization, on the one hand, these cities are grappling with day-to-day challenges of risk and security concerns related to economic, technological and social development; and, on the other hand, they are also battling with environmental challenges related to energy, its source and insufficient availability, given that conventional energy sources such as fossil fuels are fast depleting and at the same time energy requirements to drive the physical infrastructure and economic engine of these already over-populated cities are rapidly escalating – not to mention the environmental threats posed by these traditional finite energy sources notoriously known for their carbon and other greenhouse gas emissions. Abu Dhabi, one of the emirates of the United Arab Emirates, launched The Masdar City which is presently underway and being built in Abu Dhabi by the subsidiary unit of the state-owned Mubadala Development Company. (Halligan. Neil,2019)1 This paper delves into the details of Masdar City which is unique and unconventional in many ways as it embraced information and communication technologies (ICT), more visibly Internet of Things (IoT), for better quality of life and performance of services, for an ecologically-balanced integrated urban development thereby becoming a ‘Smart City’. The city further leveraged this smartness in a domain convergent with ‘Sustainability’ with technology-driven goals related to eco-friendly environment, self-generated energy availability through solar, energy efficiency and other zero-carbon features in subsystems such as transportation, civic utilities, physical infrastructure, water management, waste management and so on. Additionally, this conceptual paper reviews the case of other similar global cities and explores how Masdar can position itself as a sustainable, smart city for others to follow

Abstract
Over the years, farmer grievances have been rapidly increasing due the barrage of issues that they face on a regular basis. This includes not getting good harvests, shortage of resources, etc. Decision making is an important aspect of farming, as it can improve results tremendously, hence helping farmers. With the rise in technology, and great research in the realm of Data Science, there is an increasing demand for technical solutions for farmers. To solve this, we built a Decision Support System that predicts a crop to be grown based on agrometeorological factors such as rainfall, temperature, and humidity. The system was built using various machine learning algorithms. We compared multiple models, change algorithmic parameters, and decide the best model to be used. This system aims to aid the decision-making process of a farmer, and hence help them gain maximum yield with the knowledge and resources available.
