Laboratory Scale Arrangement for Experimental Studies of Drill-String Motions
Authors: Meryem Kanzari, Mohamed Youssef Al-Qaradawi and Balakumar BalachandranBackground & Objectives Drilling systems are used to identify geological reservoirs and carry out extraction of oil or natural gas from these reservoirs. Deep wells are drilled by using rock-cutting tools driven from the surface by a slender structure of pipes called a drill string. These slender rotating structures can experience undesired dynamics, which can be detrimental to the drilling system. As an example, it is me Read More

Transient PV System Models for Power Quality Studies
More LessIn recent years, increasing concerns about climate change and the liberalisation of the energy market have provided the necessary impetus for a revolutionary restructuring of the electricity network. Traditional power networks are designed to operate in a passive and unidirectional way as their main functionality encompasses the transfer of energy from the power stations to the customer, with minimum loss. Increased ele Read More

Fungal Diversity in the Arabian Gulf Surrounding Qatar: New Species of Yeasts and Molds
The Arabian Gulf surrounding Qatar is a unique marine environment with high insolation and salinity. Over 2000 strains of yeasts and filamentous fungi were isolated during 4 samplings in the context of a QNRF funded NPRP project. Approximately 1200 of the isolates were yeasts and over 800 were molds. All isolates were identified by molecular barcodes based on the ribosomal DNA. In addition the yeast isolates were also iden Read More

Quantification of Managed Aquifer Recharge using Passive Thermal Tomography
Authors: Chris Lowry, Thomas Glose and Elsayed FerganyManaged aquifer recharge focuses on increasing the availability of potable water within the subsurface. Under managed aquifer recharge, recycled or excess water is diverted into large infiltration basins that allow water to percolate into the subsurface thus increasing the volume of water within the shallow aquifer. Water can then be extracted during periods of increased demand and provided water security. This widely used tech Read More

Reduced LPV Modeling and Control of a Solution Copolymerization Reactor
Authors: Nader Meskin, Sandy Rahme, Roland Toth and Javad MohammadpourControlling the operation of polymer reactors is a highly important task that aims at maximizing the production rate and the product quality and also minimizing the transition losses due to the high consumer demands, as well as the tight market competition for producing different grades of polymers. However, the control design task is nontrivial due to the nonlinear behavior of polymer reactor systems which exhibit strong d Read More

Effects of Nitrogen Fertilization on Growth and Physiological Characteristics of Populus Sibirica Seedlings in a Desertification Area, Mongolia
Authors: Yowhan Son, Hanna Chang, Seung Hyun Han, Jiae An and Ji Soo KimArid and semi-arid areas where desertification mainly occurs cover up to 40? of the world's land area. Mongolia is one of the arid and semi-arid areas, which 90? of the land is in effect of desertification. The government of Mongolia recognizes the need of afforestation for combating desertification, however, there are very limited practical afforestation techniques in Mongolia. Nitrogen fertilization, a major technique f Read More

Carbon Emissions Policies and its Impact on the Design of Supply Chains
Authors: Shaligram Pokharel, Zhitao Xu and Adel ElomriCarbon emission is a concern across the industry due to its environmental impact. In order to reduce carbon emissions, industry have to look not only at their processes but also in the generation of emissions in the whole supply chain that it belongs to. This is more necessary when various forms of carbon emissions policies are faced by the industry. The current focus on research is either in the economics of supply chain or Read More
