Optical absorption enhancement for

A-SI:H Solar Cells using Plasmonic Nanoparticles

Solar energy is the most favored renewable energy that can be harvested and converted to usable electrical energy using solar cells with a drawback of limited efficiency. The light harvesting and power conversion efficiency can be boosted utilizing nanostructured materials, including nanowires, quantum dots, plasmonic materials, and Nano antennas. In this work, we propose a new structure for an excitonic solar cell with improved light harvesting and power conversion efficiency using plasmonic nanoparticles distributed on the top surface of a conical shaped solar cell. Different metals will be used as plasmonic nanoparticles such as gold, copper, silver and vanadium dioxide. Hydrogenated amorphous silicon solar cells which have very strong absorbers using n-type, intrinsic, and p-type layers will by used. Therefore only a very thin film is required to capture most of the incident light. These light absorbing molecules can also be deposited with solution processable techniques. This means that large area devices can be manufactured using simple and cheap manufacturing processes. Hence, these solar cells are relatively cheap to produce; and can be prepared as flexible devices. The flexible and lightweight nature of these cells means they are more portable than traditional solar cells and can be incorporated more easily into consumer goods, such as backpacks. Another advantage of the strong absorption properties of these types of solar cells is they perform well under low or diffuse light conditions and so can be used indoors. On the other hand, conical shape of PIN is used to enhance the light trapping by multiple reflections of incident light. The optimum shape, size and position of plasmonic materials and optimum shape and height of the PIN conical shape will be determined using a finite difference time domain (FDTD) simulation tool. According to the parametric study, we will fabricate a prototype for a solar cell that can be industrialized. Electrical and optical properties of the proposed model will be determined and verified with the ones obtained by the parametric study as well.

Assessment of quality cost in Saudi Arabia manufacturing industry

Quality costs are those resulting from producing, identifying, repairing, and avoiding defective products. It consists of the following four categories:

1) Internal failure costs are incurred prior to the products delivery to the customer. They include costs of scrap, rework, retest, downtime, yield losses or disposition.

 2) External failure costs occur after the products are delivered to the customer. They include categories such as complaint adjustment, returned products, warranty charges, and liability or allowances concessions.

3) Appraisal costs result from measuring, evaluating, and auditing material and products to determine their conformance to specifications. They include costs of inspection and testing of incoming materials, through production, testing, and equipment calibration.

4) Preventive costs are associated with activities aimed at reducing appraisal and failure costs. They include costs of quality planning and design, new products review, process control, training, quality data analysis and reporting, and improvement projects.

A survey of several manufacturing industries in Saudi Arabia will be conducted. The survey includes a cross representation of manufacturing activities existing in the region. They include construction material, light metal fabrication, plastics and glass products, and assembly of various electric & mechanical products and home appliances.

The survey is intended to assess the level of awareness and quantitative estimates of quality costs as related to the above four categories. The survey design and findings will be presented along with analysis. Specific conclusions will be drawn regarding quality costs studies and reduction/improvements programs as related to the surveyed industry categories.

Piezoelectric for lighting highways

Sound is a regular mechanical vibration that travels through matter as a waveform. Longitudinal sound waves – compression waves – transmitted through the ambient air are made up of waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction. In This work, different intensity of the input sound was used.

Compared with other mechanical energy sources, it is very difficult to use mechanical energy from sound in order to generate electrical energy using a conventional PZT-based bulk or thin film piezoelectric energy harvester." To overcome this difficulty, the team worked with zinc oxide nanowires, a piezoelectric nanomaterial that leads to a much more sensitively response

Novel design and implementation of Chip-less tag using radio frequency identification (RFID) system

Radio-Frequency Identification (RFID) wireless technology is becoming the most popular and important instrument that is used in many applications such as logistic chains, tracking and localization items. RFID has the capability to read the items without needing line of sight. In addition, RFID is used for applications that require relatively long reading distance compared to the traditional barcode system. The main obstacle of the RFID system is the cost of an active tag unit as well as a passive tag unit with chip, and this still prevents RFID from being a widely used identification system.

Chip-less tag is one solution to effectively reduce the cost of the tag. However, this solution imposes new challenges in RFID systems. One of the main classical challenges is the development of anti-collision methodologies in order to identify multiple tags simultaneously. The anti-collision protocols that are frequently used in traditional active and passive RFID tags with chips are not suitable for chip-less tags, since chip-less tags do not have any on board controlling element (chip) or circuit. Therefore, new anti-collision protocols should be developed for chip-less tags. In this project we will design a microstrip printed antenna using an Ink-Jet printer in our lab at the University of Business and Technology.

In this research project, it is intended to design and develop new chip-less tags that should be extremely cheap. The new tags will need the development of new protocols for reading multiple tags simultaneously. As a result, this will open the way for building an initial prototype of an enhanced passive RFID system.

Modeling and Implementation of Grid Connected Hybrid Wind/Spv System and Application for Saudi Site

The shortage of fuel resources worldwide has required urgent search for alternative energy sources to meet up present day demands. Solar and wind energy sources is a clean, unfailing and environment-friendly potential resource among all renewable energy options. At present, there is a need for continuous supply of energy, which cannot be satisfied - due to seasonal and periodic variations – solely by a wind energy system or solar photovoltaic system.

Hybrid PV/battery bank/utility grid system (PV/BB/UG) is considered as a basic solution for any shortage of fuel resources worldwide. The overall cost of such hybrid system is the main issue that should be studied deeply before installation of the system. This research introduces a complete study of the performance of a hybrid PV/BB/UG system. The cost of kilo Watt of each individual source has been calculated and the kWh cost of the overall PV/BB/UG İs calculated as well taking into consideration the installation and running cost. The introduced system is simulating on a real load of a building at the University of Business and Technology located in Dahban, Jeddah, Saudi Arabia. Finally, we used our study in lighting some labs in the same engineering building.

It is generally agreed that using local information such as generated power from PV array and state of battery change are calculated using computer program under known insolation and load demand. The optimal power management is carried out using the designed program which has been tried and tested using actual data – under different operational conditions. Matlab-Simulink is used for carrying out a simulation using daily data of the load demand, insolation and temperature of Jeddah site, KSA. The results obtained show the beneficially of the hybrid integrated system

Simulating Ultra-Sensitive Gas Sensors Using Plasmonic Nanostructures

Gas sensors are important for a myriad of applications including petroleum production, automotive industry, agriculture, and environmental studies. Excellent gas sensors should be ultra-sensitive, selective, cheap, simple, energy efficient, feasible, fast in response, and can be used for a wide range of applications. Furthermore, the general architecture of the sensor should remain constant even if sensing materials or detected gases are changed.

Unfortunately, the reported techniques in the literature partially have the characteristics of ideal gas sensors. As a result, we propose to use the finite difference time domain (FDTD) method to simulate gas sensor designed by using plasmonic gold nanoparticles and gas sensitive polymeric materials. We plan to monitor only one physical quantity that will be changed in all chemical reactions between sensitive polymers and gases. Therefore, the basic structure of our proposed sensor will be fixed and only the sensitive polymeric materials can be changed. In addition, the proposed method will have the same advantages of traditional polymeric gas sensors but with extra sensitivity improvement. Also, the proposed sensor can be simulated above flat surfaces or optical fibers which widen its applications area.

A framework to evaluate the state of food retail supply chain in Saudi Arabia

Supply Chain Management has been playing a key role in food retail business in developed countries by providing various segments of customers with quality products in a highly efficient manner. The Kingdom of Saudi Arabia (KSA) is following the lead of developed countries, with rapid growth trend in super and hypermarkets. However, the role of supply chain management and its impact on meeting customer needs are not well understood because of lack of readily available data. There is need to develop an appropriate framework for the KSA food retail sector to study the impacts of the various elements of the supply chain. This paper describes a framework that researchers can utilize to study the supply chain impacts on the food retail sector.

Fabrication Of A Microelectrode Array, First Generation, Glucose Biosensor- PHASE I

The worldwide market for bio and chemical sensors is large, being valued at $13 billion in 2011, and growing quickly with a projected compound annual growth rate of 9.6% between 2011 and 2016. Many of these sensors are amperometric, where the concentration of a chemical analytic (e.g., free available chlorine, ozone, glucose) is determined by measuring the diffusion limited current at an electrode.
The electrodes used in the majority of these sensors are macro electrodes. Macro-electrodes are electrodes where the smallest electrode dimension is > 50 micrometers. The response of such electrodes depends greatly on the mass transport conditions in the analytic solution. The response at microelectrodes where the smallest electrode dimension is less than 50 micrometers, and is independent of mass transport. However, the current generated at such electrodes is very small and is difficult to measure. This problem can be overcome by measuring the aggregate current generated at an array of microelectrodes.

Fabricating such microelectrode arrays in a cheap and efficient manner is a technological challenge that has not been fully solved (please see Literature Review), as demonstrated by the low usage of these electrodes in commercial amperometric sensors. The researchers will build on work completed in the University of Limerick to first construct a microelectrode array, first generation, glucose biosensor and then similar sensors for other analytics.

Preparation of Hybrid Composite Materials And Their Microwave Properties Applied on The Telecommunication Towers In Jeddah – Proof of Concept

The extensive development of telecommunication systems and electronic devices has raised the electromagnetic pollution to a level never attained before. This has led to environmental questions, health concerns and a wide variety of applications. This justifies an active quest for novel and effective electromagnetic material creation that could provide solutions for the microwave behavior. Thus, materials with high efficiency to diminish electromagnetic interferences pollution have become a mainstream field of research. 

The present project will focus on the preparation, fabrication and development of hybrid composite materials to reduce the electromagnetic pollution that is produced by the telecommunication towers in Jeddah. These materials are expected to act as a  barrier, absorber, or reflector of the electromagnetic radiation. Protection of humans and other biological objects from the harmful action of the electromagnetic waves will therefore be achieved. These materials are expected to be implemented in different applications – i.e. antenna techniques and production, military applications, and improving the electromagnetic compatibility between different electronic devices.

Design of a Data Warehouse Model for Decision Support in Higher Education: A Case study at the University of Business & Technology (UBT)

The goal of this study is to design a Data Warehouse (D W) dimensional model at the University of Business and Technology (UBT). UBT is striving to be a world-class university. For this purpose several Information Systems (IS) were developed such as 
OPERA. Unfortunately, these systems are transactional systems that support day-to-day decision-making. However, these systems have failed to support strategic decisions. Hence, a DW design at UBT is essential to stay competitive in a rapidly changing world. OPERA system is the most critical IS at UBT since it contains undergraduate students’ information. In this study, a dimensional model will be designed for student academic examination data and human resources data. A prototype will be developed and evaluated based on the proposed model. The proposed model will help decision makers at UBT to make better strategic decisions in terms of academics and human resources perspective.

Flame spray Drying Synthesis of Calcium Phosphate Nanoparticles

The investigators propose to study the synthesis of calcium phosphate nanoparticles using the flame spray pyrolysis technique. Calcium phosphate salts are important biomaterials and flame spray pyrolysis is a fundamentally important technique extensively used in industry for the formation of metal oxide 
nanoparticles. Studies have previously been performed on the flame spray synthesis of calcium phosphate salts but such studies have not been systematic and have not considered in detail the treatment of the precursor solutions and the effect that such treatments have on the calcium phosphate phases produced. 
It is the purpose of this study to comprehensively characterize the flame spray system with a view to synthesizing calcium phosphate particles of controlled particle size and phase (e.g. hydroxyapatite, tricalcium phosphate, intimately mixed compositions of both phases) in a manner that is readily amenable to scaling so that a clear path to commercialization of the technology is outlined. 


It is also a goal of this research to develop expertise in flame spray technologies to enable the researchers to develop further projects where nanoparticles of other compositions will be synthesized.

Empirical Asset Pricing Saudi Stylized Facts and Evidence

I estimate proxy specifications of (Fama and French, 2014) five-factor model to produce stylized facts of the Saudi capital market and test an APT model. The data set is the panel of all publicly traded firms, excluding financial and negative book value of equity firms. My contribution to the extant literature is three-fold: [1] organizing Saudi market data based on beta and firm-specific fundamentals, namely, growth, size, accounting earnings, and equity investments, [2] conducting a parsimony analysis within the theoretical framework of Merton's (1973) APT, and [3] quantifying the information risk facing marginal investor by decomposing earnings into cash flows and accruals; and investigating respective loadings in an unrestricted version of the parsimonious specification. Proxy asset pricing specifications, though intuitively appealing, are scant due to lack of theoretical frameworks and misguided significance tests of factor loadings. Throughout, I address this issue in detail and keep the empirical analysis under describing market facts and testing an APT model.
