The method used in this study involved data collection of all raw cooking oil produced in Kuwait and exported to it for the past three years, which represents the overall amount of cooking oil within the country. This is followed by a calculation of the estimate used cooking oil produced from its initial stage. The estimated amount is then forecasted to determine the future changes in quantities and compared to diesel fuel in terms of cost, energy production, and environmental effects. The research findings showed that used cooking oil can be utilized as a supportive source of energy in Kuwait with minimum environmental impact compared with diesel fuel.

Volumetric engine inertial unbalances and road profile irregularities create mechanical vibrations. The purpose of this study is to employ optimization algorithms to identify structural elements that contribute to vibration propagation and to provide optimal solutions for reducing structural vibrations induced by engine unbalance and/or road abnormalities in a motorcycle. The powertrain assembly, swing-arm assembly, and vibration-isolating mounts make up the vibration-isolating system. Engine mounts are used to restrict transferred forces to the motorbike frame owing to engine shaking or road irregularities. Two 12-degree-of-freedom (DOF) powertrain motorcycle engine systems (PMS) were modeled and examined for design optimization in this study. The first model was used to compute engine mount parameters by reducing the transmitted load through the mounts while only consi...

In this work, a new experimental method is proposed for producing diesel-like fuel from the waste engine oil. The study proposes new physical and chemical treatment methods to produce diesel-like fuel from the used engine oil. The produced oil is chemically analyzed to characterize the produced engine oil fuel for application in a diesel engine, to calculate the power produced, to measure the gaseous emissions and to compare with the standard diesel fuel. The diesel-like fuel properties are investigated including viscosity, flash point, pour point, energy content, and gaseous emissions. The diesel-like fuel proves to emit less gaseous pollutants such as NOx than the diesel fuel. The diesel-like fuel is tested in a diesel engine which provided the efficiency of 22.4%. The proposed experimental approach pro...

This accounted for 27.2 TWh of electricity consumption with 14.2 MWh/capita/year in Kuwait. In this research, four offices in an educational building were equipped with a meteorological data logging system using temperature, humidity, and illuminance sensors. All four offices had double-glazed windows. Moreover, two offices were equipped with two types of commercially available window films. Two million data were stored in iCloud using Wi-Fi and an Internet of Things (IoT) system for the 3 months of June, July, and August 2019. Here, histograms and the kernel density estimation (KDE) of temperature/humidity were analyzed and compared for the two offices with/without 3M Neutral 20 window films. Two floors of the same building consisting of 31 offices were also modeled and simulated to study energy saving and CO2 footprint reduction using various...

In this study, we used a hybrid molecular dynamics-finite element-musculoskeletal model to determine the level of loads the knee can withstand when landing from different heights (20, 40, 60 cm), including the height at which cartilage damage occurs. The model was driven by kinematics–kinetics data of asymptomatic subjects at the peak loading instance of drop landing. Our analysis revealed that as landing height increased, the forces on the knee joint also increased, particularly in the vastus muscles and medial gastrocnemius. The patellar tendon experienced more stress than other ligaments, and the medial plateau supported most of the tibial cartilage contact forces and stresses. The load was mostly transmitted through cartilage-cartilage interaction and increased with landing height. The critical height of 126 cm...

While the techniques presented herein are general, the application of proposed techniques is demonstrated primarily through applications in motorcycles. The dynamic loads that are generated due to the shaking forces within the engine and the road loads that are transmitted to the engine through the tire patch are discussed. The geometrical shape of the engine mount is also considered in this work. All models discussed herein deal with solving the optimization problem for the engine mount system such that the transmitted forces to and from the engine are minimized in which the mount parameters are used as design variables. While work has been done in the past in the area of engine mount design, this dissertation tries to fill in the gap when it comes to designing a comprehensive mounting system that takes into account modeling of the mount characteristics, the excitation load present in the system, and a determination of the final geometrical shape of the engine mount. mount geometrical parameters such as the mount diameter and the thickness are used as design variables. Numerical examples are provided quantifying how mount geometrical parameters vary for different operating engine speeds. All the models and techniques developed in this work will help designers comprehensively design a mounting system that achieves an effective vibration isolation of the powertrain assembly. v ACKNOWLEDGMENTS I would like to thank my advisor, Professor Anoop Dhingra, for his continuous guidance, patience, support and friendship throughout my dissertation work. I appreciate

Embedding the internationalization process within the CDIO context would certainly benefit the higher education institutions and the attributes of their graduates. This paper suggests embedding implicitly the internationalization process within the CDIO standards without the needfor creating additional mandatory or optional ones. The case of institutionalizing the internationalization process at the Australian College of Kuwait is then presented and discussed.

Its structural functions include providing support for the body against gravity, and static and dynamic loadings. It also acts as a rigid lever system for the muscular action, and serves as a protective covering for the vital internal organs such as the heart, brain, and blood forming marrow. The primary metabolic function of bone lies in the ability to serve as a repository to calcium, which is necessary for nerve conduction, muscle contraction, clot formation, and cell secretion. Evidence is also accumulating to suggest that bone plays a major role in the induction of hemopoietin marrow [1]. A study done by Milovanovic et al. [2] suggests that bone fragility is highly affected by age which in turns increases the risk of fractures. The study shows that the femoral neck fracture is among the highest rates of fracture and is highly affected by age and gender of the patients. The study used atomic force microscopy (AFM) for imaging and mech...

We examined SIRD model for development of COVID-19 in Kuwait which was started on 24 February 2020 by 5 patients in Kuwait. This paper investigates sensitivity of SIRD model for development of COVID-19 in Kuwait based on duration of progressed days of data. For Kuwait, we have fitted SIRD model to COVID-19 data for 20, 40, 60, 80, 100, and 116 days of data and assessed sensitivity of the model with number of days of data. The parameters of SIRD model are obtained using an optimization algorithm (lsqcurvefit) in MATLAB. The total population of 50,000 is equally applied for all Kuwait time intervals. Results of SIRD model indicates that after 40 days the peak infectious day can be adequately predicted; althogh, error percentage from sensetivity analysis indicates that different exposed population sizes are not correctly predicted. SIRD type models are too simple to robustly capture all features ...

Window films are passive thin films stick to the interior or exterior of windows to effect various solar-optical impacts including energy saving, UV reduction, and increased thermal comfort. For this study, the 3M Neutral 20 and 70 are selected which are made of multilayer nanofilms of 220 SAN25/THV 95-nm thick reflective layers. Real-time measurements of temperature, humidity, and luminous were conducted in 5 min intervals over the months of June, July, and August 2019 and data stored through WiFi system in iClouds. Arduino-type microprocessors and various temperature-humidity, and LUX sensors were assembled and programmed to transfer and store data in real time. Exploring and analyzing the data collected for four offices with and without window films in summer of Kuwait, it is evident that window film has good potential to save water by preserving interior humidity to the level of human comfort, decrease interior temperature to save energy and reduce CO2 footprints, to restrict the solar UV rays to minimum level, and to reduce visual impacts of high solar luminous. The benefits and drawbacks of the selected window films are discussed here for the weather condition of Kuwait.

However, the question remains is that how large a wind turbine is the optimum size for a selected wind site? To answer this, three important objective functions, the levelized cost of electricity (LCOE), the capacity factor (CF) and a normalized annual energy production (AEP) are optimized versus the rated wind speed. Four empirical power curve models for large wind turbines and Weibull wind distribution are investigated to produce a Pareto front within range of practical wind conditions. It is observed that the optimized values of the objective functions are merely dependant on the Weibull shape factor, k. Also, the optimum rated wind speed is a linear function of the Weibull scale factor, c. Therefore, it is concluded that, there are limits for the optimum rated wind power and the costs. Consequently within the Pareto front, the lower rated power wind turbines may be selected to reduce LCOE albeit the higher rated power wind turbines may be adopted to produce higher AEP and CF.

The model presented herein consists of two main assemblies. The powertrain assembly and the swing-arm assembly are modeled as a six degree of freedom rigid bodies. The two assemblies are connected to each other using a shaft that is usually referred to as the coupler. The connection points on both assemblies are known. Unlike automobiles, motorcycle performance and handling is highly affected by the external disturbance. In addition to minimizing the shaking loads, the mounting system must be set up such that it also minimizes the external disturbance from the environment such as irregularities in the road profile and road bumps. This disturbance can be transmitted through the tire patch to the engine causing it to hit nearby components. The engine movement needs to be minimized due to space limitations surrounding the engine. In order to do so, these transmitted external loads must be minimized by the use of the mounting system. The load minimization process is achieved by selecting the optimum stiffness parameters, location and orientation of the mounting system that are supporting the engine. This goal is achieved by an optimization scheme that guarantees that the transmitted loads are minimized. An investigation will be done to explore the effect of different road profiles on the mount final geometrical shape.
