The influence of different ignition timings and compression ratios on the combustion characteristics and performance of a gasoline direct injection GDI engine operating on gasoline and liquefied petroleum gas (LPG) fuels at a constant speed of 3000 rpm were numerically investigated. For this reason, a model was created and developed using the AVL Boost program (fully integrated IC engine simulation software). The results of this study showed that the effective power and effective torque were decreased for engines fueled with LPG compared to those of gasoline for all selected ignition timings. Also, brake specific fuel consumption was higher for LPG fuel than for gasoline fuel, but brake mean effective pressure, maximum cylinder pressure, and maximum cylinder temperature were higher for gasoline fuel than for LPG fuel. Increasing the compression ratios resulted in an increase in the effective power, effective torque, brake mean effective pressure, peak cylinder pressure, and peak cylinder temperature, but it also resulted in a decrease in the specific fuel consumption for both fuels.

Container-based virtualization is quickly becoming the standard method for developing and deploying applications. Kubernetes is a well-known open-source project that provides a platform for containerized application orchestration. In such a container-based environment, it is critical that Kubernetes can monitor the cluster computing resource as well as the resource requirements of the running pods. The goal of this paper is to introduce a generic framework which is named as Kube-Monitor for real-time monitoring of a heterogeneous Kubernetes cluster's resources, which include traditional data center devices and raspberry pi devices, as well as monitoring pod resource requirements. Kube-Monitor will collect 15 different cluster resource metrics and update their values every five seconds. As a result, the Kubernetes operator can use the Kube-monitor framework to view a comprehensive set of continuously updated resource metrics.

Streets are the most important parts of the city because they are the lifelines of cities and provide corridors and means of communication within cities and ways of interaction between activities. As well as being a place for social interaction among the residents. The availability of sustainable streets is an important part of the city's sustainability. This research discusses the criteria adopted to achieve sustainability in the streets, and then analyzes the reality of the streets in the study area, and compares with the sustainability indicators for each street. The research found that all the streets chosen in the city of Kut are very far from sustainability standards and do not match any international standards, as street designs encourage private cars at the expense of most other means of transportation, and the absence of institutional organization, as most streets lack the safety factor and the lack of response to the designs of conditions environmental.

In this work, 2D numerical simulation Pd/pentacene/Al planar Schottky diode using technology computer aided design (TCAD) has been reported. The TCAD is utilized to design and characterize the proposed organic Schottky diode. The current-voltage curve is performed at temperatures ranging from 260 K to 380 K with a step of 20 K. The effect of increasing the temperature on the device parameters, such as rectification ratio, barrier height, and ideal factor, is investigated. The calculated values for the main parameters at room temperature are saturation current (Is) = 3.53×10−12 A, barrier height (ΦB) = 1.18eV, ideal factor = 2.17 and rectification ratio = 3.55×106. The device exhibits with the increasing temperature a decrease in the ideal factor and rectification ratio and an increase in the barrier height and the saturation current. We also noticed that the value of the Richardson constant calculated conventionally from the temperature-dependent characteristic curve is much less than the theoretical value that we calculated by applying Richardson constant equation.

The demand for network capacity has been steadily increasing in recent decades due to the growth of new digital applications and services. Optical fiber supports to solve and avoid data traffic bottlenecks when dealing with high capacity data rate requirements. When fiber is used as a propagation medium, fiber dispersion and nonlinear distortions effects appear. Dispersion in optical fiber is a linear effect that may be compensated by a dispersion compensating fiber. In contrast, the nonlinearity effect is one of the most unfavorable aspects of modern communication systems causing intermodulation distortion, adjacent channel interference, phase distortion, and harmonic distortion. In the majority of communication systems, the primary fiber nonlinear effect is the Kerr nonlinearity caused by the refractive index dependency on signal intensity. The purpose of this paper is to summarize a survey of fiber nonlinearity compensation techniques to minimize the effect of nonlinear distortion that improve the performance of optical communication network. The conclusions showed that there are two types of compensation, digital and optical. Optical compensation has better advantages than digital compensation in terms of efficient improving system performance and increasing data rate against nonlinear effects, especially for advanced systems with high capacity.

Residential buildings are built to accommodate daily uses which need energy for heating, lighting, and cooling. Net-zero energy building (NZEB) is a building that makes a balance between the energy supply and production by decreasing energy demand and generating power using renewable resources. Building-integrated PV/T systems (BIPV/T) increase the total energy gain and take advantage of cooling fluid as a heat provider for buildings. Building information modeling is used as a virtual simulation to an existing apartment building of the Bismayah project to measure the effect of adding (BIPV/T) systems to the conventional power sources. Results showed the effectiveness of renewable power collectors in (heating, cooling, lighting, etc.) with the recommendations to increase the self-dependency of power building depending on renewable power sources.

In this paper, the effect of transceiver impairment on the capacity of the MIMO system is studied. Different from the conventional knowledge that the correlation among antenna elements degrade the system performance, this paper proposes an algorithm that simulates the capacity of the correlated MIMO channel that suffers from Rayleigh flat fading with the presence of a physical transmitter and physical receiver. We also assume that the channel state information at the receiver (CSIR) is available. Also, this work will be devoted to long-term evolution systems (LTE). The simulation process of the proposed algorithm is manipulated by MATLAB software with 10000 realizations of the channel. Each realization of the channel is generated randomly. The transceiver impairment levels (k) used in the simulation are 0.08 and 0.175. The simulation results of the proposed algorithm showed that the capacity of the correlated MIMO channel with the presence of a physical transmitter and physical receiver is stopped growing at a particular value in the high SNR regime, which is called the capacity limit. Also, the results showed that the correlation coefficient has an influential role in determining the value of the capacity limit. These results contradicted the results of the traditional MIMO system, in which the traditional MIMO channel capacity grows infinitely at the high-SNRs regime.

Numerical models utilizing the finite element technique through Plaxis program package were conducted in this study to investigate the behavior of a concrete retaining wall in sand soil. The proposed numerical model intended to predict the behavior of retaining wall under many factors. A parametric study is focus on the effect of various parameters on the behavior of concrete retaining walls. These parameters included the wall height, geogrid reinforcement, embedment ratio of geogrid and surcharge loads on top of backfilling. Three different heights were tested D (4, 6, 8) m and four values of surcharge were tried (100, 200, 300, 400) kN/m2. The geogrid layer was furnished in three locations according to the height of the wall h/D (0.25, 0.5, 0.75) to investigate the embedment ratio on the retaining wall. It was found that increasing the wall height leads to increase the active pressure of soil and the stem of wall will tilt away from the backfill. The foundation of the wall was rotated counterclockwise when the height of wall increased from 4 to 8 m. The location of external load is effective in increasing the value of displacement and these values are reduced when the distance of load moved away from wall stem. The presence of geogrids reduces both vertical and horizontal displacements. The geogrids change the direction of horizontal displacement at bottom of the stem and the movement changed from negative to positive direction due to redistribution of active pressure on the wall due to geogrid effect.

The emergence of COVID-19 pandemic led to an increase in establishing methods of sterilization and prevention, and also in the searching for sterilization methods at the lowest cost and most effective in eliminating viruses. Robots are widely used in many fields including the sterilization to reduce the risk to human life. This work presents a design and implementation of robot for automatic surface disinfecting using Ultraviolet (UV) lights. Arduino UNO R3 is used as micro controller to control the movement of the mobile robot and three ultrasonic sensor which used to avoid robot collision with obstacles. UV lights are used in the sterilization processes of surfaces, air and water, as it ruptures the DNA of bacteria or viruses and thus prevents it from reproduce. Eight UV lights are used in this research work which are fixed around the mobile robot. The results showed the low cost with robot using for surface disinfecting can be obtained with using simple sensors and actuators components and UV lights, as well as being safer for humans than using chemical disinfectants.
