    A poster submitted in ENG 207 taught by Dr. David Prescott for the Fall 2016 semester.VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 250 meters of each other to connect, creating a network with a wide range.[6] As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. These networks have no fixed infrastructure and instead rely on the vehicles themselves to provide network functionality

    No full text
    Water and sediments were collected on March 2013 and April 2014 from Khalid Khor creek area in United Arab Emirates to assess their quality parameters. The pH and alkalinity of the water samples were measured and their values were similar to those of shallow saltwater ecosystems. In addition, elemental analyses and organic compounds were done using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) and Gas Chromatography—Mass Spectroscopy (GC–MS), respectively. The concentration of heavy and trace metals in the water samples were within the acceptable limits except for lead which showed high values, while the concentrations of metals in the sediment samples were relatively high and ranged from 6517 to 13,768 mg/kg. GC–MS analysis showed the presence of polyaromatic heterocyclic (PAHs) compounds in sediments near the shipping area and in amounts classified as highly carcinogenic; however, no polychlorinated biphenyls (PCB) were identified. Moreover, fecal bacterial contamination in water was detected in concentrations that range between 300 and 10,140 organisms/100 mL

    A Master of Science thesis in Electrical Engineering by Bassel Mohamad Al Homssi entitled, "Portable Electromagnetic Surface Profiling System," submitted in June 2016. Thesis advisor is Dr. Nasser Qaddoumi and thesis co-advisor is Dr. Bassam Abu-Nabah. Soft and hard copy available.Due to its potential accuracy and speed, the use of profiling and detection sensing systems has been gaining rapid popularity in the industry. Whether they are implemented in coordinate measurement machines or encoded in custom-designed measurement systems, real-time accuracy and precision in determining the sensor position and orientation are crucial elements to the performance of inspection sensor measurement techniques. Uncertainty in tracking these sensors within a measurement system can adversely affect the quality of 3-dimensional surface profiling techniques. Recent advancements in micro-electro-mechanical systems and their applications in multiple-axis inertia measurement units (IMUs) have been offering relatively high accuracy and precision in determining linear accelerations and angular velocities within the operating range of inspection measurement systems. This effort targets taking a step forward towards integrating IMUs to offer robust and portable inspection measurement systems. Utilizing the gyroscope as a feedback, different forward models will be analyzed to accurately extract gravitational acceleration from IMU's accelerometer measurements at random real-time orientations simulating realistic measurement environments. Accuracy in the forward model lends itself for real-time assessment of a sensor's position and orientation as part of the inverse model, which will be investigated with different physics-based data processing techniques. Forward and inverse models and their real-time transformational matrixes allow taking a point from the sensor coordinate system to the world coordinate system. The developed models are tested for dimensional accuracy against known input profiles to show the potential capabilities and limitations of the proposed effort. Using the proposed algorithm, the drift bias error was minimized drastically demonstrating potential in usage as an alternative to bulky profiling machines used conventionally.College of EngineeringDepartment of Electrical EngineeringMaster of Science in Electrical Engineering (MSEE

    Hydrogen Fueled Home Generators

    A poster submitted in ENG 207 taught by Dr. David Prescott for the Fall 2016 semester.Burning fossil fuel, such as coal, oil and natural gases contribute to pollution and global warming due to the emission of carbon dioxide. 33% of green house emissions are due to electricity generation, which is the highest percentage amongst other factors. Also, fossil fuels are finite resources that will eventually deplete. The suggested hydrogen fuel cell does not burn oxygen rather it simply combines itself with oxygen from air to form water. Hydrogen fuel was already integrated to cars such as BMW 740i Sedan, but this concept has not yet been integrated to home generators

    Analysis of Non-Yielding Basement Wall Adjacent to Strip Footing

    A Master of Science thesis in Civil Engineering by Majid Omar Touqan entitled, "Analysis of Non-Yielding Basement Wall Adjacent to Strip Footing," submitted in May 2016. Thesis advisor is Dr. Magdi El-Emam. Soft and hard copy available.Foundation depth below the ground surface is one of the major factors that contributes to the bearing capacity and settlement of shallow foundation. Hence, it is common to find adjacent buildings on shallow foundations that are constructed at different depths. This situation leads to geotechnical and/or structural problems especially when a shallow foundation is constructed adjacent to a basement wall. A literature review and communications with local municipalities indicated that there is no solid code of practice that can be adopted to solve problems of shallow foundations constructed adjacent to non-yielding wall. The objective of this research is to study the behavior of non-yielding walls adjacent to strip footing experimentally and analytically. Parameters investigated during this study are footing depth below ground surface, horizontal distance from the basement wall to the footing, footing contact pressure, and width. To achieve these objectives, 15 reduced-scale wall-footing model tests with 1.15 m height by 1.4 m width and 2.7 m in length were constructed with well graded backfill sand. The strip footing was subjected to an incremental vertical stress until excessive deformation occurred. The wall-footing models were instrumented to measure lateral wall deflection, footing vertical stresses and settlement, horizontal forces transferred to the top and bottom boundaries of the wall, and vertical force transferred to the bottom of the non-yielding wall. Results showed that the non-yielding wall and the adjacent strip footing are working interactively, and the load capacity of the strip footing was affected significantly by the behavior of the non-yielding wall. Location of the footing relative to the wall, the footing width, and the footing embedment depth were the major parameters that influenced the wall-footing responses. The existence of the strip footing in the vicinity of the basement wall imposed significant vertical and horizontal forces at the wall top and bottom boundaries. A comparison between experimental results and results from the elastic theory method in combination with Jacky formula for lateral earth pressure at rest indicated that the analytical method underestimated the lateral earth forces on non-yielding walls due to strip footing. Therefore, a modification of the current used analytical methods was suggested to improve its accuracy. Finally, the experimental and analytical results indicated that the location of lateral forces above the wall bottom boundary was changed with the footing design parameters.College of EngineeringDepartment of Civil EngineeringMaster of Science in Civil Engineering (MSCE

    A poster submitted in ENG 207 taught by Dr. David Prescott for the Fall 2016 semester.Bangladesh is a flooding hotspot as 80% of Bangladesh is considered to be floodplain. It also has an extensive sea coastline, putting the nation at a high risk of experiencing periodic widespread damage. On average, in Bangladesh, about 18% of the country is flooded annually. However, in severe cases, the percentage of the total flooded can go up to 55%. Majority of the country's population live in rural areas

    Proton conductivity and morphology of new composite membranes based on zirconium phosphates, phosphotungstic acid, and silicic acid for direct hydrocarbon fuel cells applications

    The effect of Phosphotungstic acid (PWA) on the proton conductivity and morphology of zirconium phosphate (ZrP), porous polytetrafluoethylene (PTFE), glycerol (GLY) composite membrane was investigated in this work. The composite membranes were synthesized using two approaches: 1) Phosphotungstic acid (PWA) added to phosphoric acid and, 2) PWA + silicic acid were added to phosphoric acid. ZrP was formed inside the pores of PTFE via the in situ precipitation. The membranes were evaluated for their morphology and proton conductivity. The proton conductivity of PWA-ZrP/PTFE/GLY membrane was 0.003 S cm-1. When PWA was combined with silicic acid, the proton conductivity increased from 0.003 to 0.059 S cm-1 (became about 60% of Nafion’s). This conductivity is higher than the proton conductivity of Nafion-silica-PWA membranes reported in the literature. The SEM results showed a porous structure for the modified membranes. The porous structure combined with this reasonable proton conductivity would make these membranes suitable as the electrolyte component in the catalyst layer for direct hydrocarbon fuel cell applications

    Contextual Emphasis in the Holy Quran and its Translation into English

    A Master of Arts thesis in Translation and Interpreting MATI (English/Arabic/English) by Shaman Alsharou entitled, "Contextual Emphasis in the Holy Quran and its Translation into English," submitted in November 2016. Thesis advisor is Dr. Basil A. Hatim. Soft and hard copy available.This thesis tackles the translation of emphasis in the Holy Quran. To achieve this aim, relevant translation theories are invoked, and the context of the Quranic text carefully examined. The use of emphatic devices (my chosen area of research) depends on the context of situation, including the 'state' of the text receiver (denial, indifference to or acceptance of the message). However, having no equivalent emphasizers in English to the ones found in the source text, or failing to spot the significance of these emphasizers, can lead to problems in the translation process. Loss of emphatic meaning is one of the more subtle challenges facing translators of the holy Quran. With the relation between emphasis and context in mind, this thesis will thus assess two major translations of the Quran by Muhammad Marmaduke Pickthall (1930) and by Arthur Arberry (1955). Selected dialogues from the surahs of Yusuf, Hud, Al Shuara and Taha are analyzed, and alternative translations proposed in an attempt to adequately compensate for any loss of meaning related to emphasis that may have occurred.College of Arts and SciencesDepartment of Arabic and Translation StudiesMaster of Arts in English/Arabic/English Translation and Interpreting (MATI

    A poster submitted in ENG 207 taught by Dr. David Prescott for the Fall 2016 semester.The world consumes a total of 94 million barrels of oil per day. The global demand for oil is increasing exponentially while the remaining supply has been decreasing at a faster rate as shown in Figure 1. Burning of fossil fuels produces greenhouse gases that are responsible for global warming, the melting of the icecaps and the degradation of the Ozone layer. By the year 2050, emissions from our vehicles will make up to 50% of the total worldwide emissions
