Business logic extraction is a very important concept in the realm of object oriented software engineering as it deals with reusability to a great extent. Proper reusability of existing systems (legacy systems) to accommodate required changes thereby transforming existing systems into new ones is an important consideration of object oriented development. This yields several significant advantages such as cost reduction, scheduled development and minimal learning overhead etc. In this paper, we propose a novel method for extracting business logic from existing system. The method developed for extracting business logic in an existing system follows a static-analysis based approach. The method relies on analyzing the source code of the system independently from any input which requires an execution of the system. © 2015 IEEE. Source

Cloud computing covers a wide range of applications, from online services for the end user. It becomes the new trends for most organizations to handle their business IT units. Services provided are becoming flexible because the resources and processing power available to each can be adjusted on the fly to meet changes in need [6]. However, infrastructures deployed on a cloud computing environment may induce significant performance penalties for the demanding computing workload. In our doctoral research, we aim to study, analyze, evaluate and improve performance in cloud computing environment based on different criteria. To achieve the thesis objectives, a research performed is based on a quantitative analysis of repeatable empirical experiment. © 2015 IEEE. Source

This paper presents an approach to enhance students' academic engagement with their university, as well as assisting them in understanding their current academic state by using mobile technologies. This approach simplifies the presentation, awareness of university rules and regulation in regards to graduation requirements, in credit hour system, through the development of a friendly mobile environment called UniApp. A test case is presented of an interactive mobile learning (mlearning) environment in higher education institutions that adhere to university rules and regulations. Normally, students login frequently to their university account in order to use some of the provided faciliies, such as marks and registered modules. However, students need to be aware of what they are studying and what learning outcome they need to achieve. They also need to be aware of how this can benefit them in completing their major, as well as having an enjoyable learning experience. Source

Lipids in Health and Disease | Year: 2014

Background: Fatty acid-binding protein 2 (FABP2) is an intracellular protein expressed exclusively in the enterocytes of proximal small intestine. FABP2 has a high affinity for saturated and unsaturated long-chain fatty acids and is believed to be involved in the absorption and transport of dietary fatty acids. Methods. This is a case-control study conceded in 438 T2DM cases and 460 subjects with normal glucose levels and non-obese considered as healthy controls. Allelic discrimination was performed using TaqMan single-nucleotide polymorphism was carried out by real time-polymerase chain reaction (RT-PCR) assays using purified DNA. Results: Clinical data and anthropometric measurements except age, glucose levels and lipid profile of the patients were significantly different from those of the controls (p < 0.05). Statistical analyses failed to show any type of significant association of the polymorphism between cases and controls. However logistic regression analyses was suggests that the TT genotype is significantly associated with male patients (p = 0.001). None of the allele or genotypes of FABP2 A54T was associated with T2DM cases versus the controls (AT genotype, OR = 0.85 (0.64-1.12), p = 0.25; TT genotype, OR = 0.66 (0.39-1.11), p = 0.11; T allele, 0.82 (0.67-1.02), p = 0.08). Conclusion: In conclusion, this study suggests that the above named variant in FABP2 gene is not potential contributor to the risk of T2DM and related traits in a Saudi population. However TT genotype is a risk factor for the disease in males. © 2014 Alharbi et al.; licensee BioMed Central Ltd. Source

Type 2 diabetes mellitus (T2DM) is a chronic degenerative disease, phenotypically and genetically heterogeneous, characterized by high levels of glucose and metabolic complications. Insulin receptor substrate 1 (IRS-1) plays a key role in the insulin-stimulated signal transduction pathway. A glycine-to-arginine substitution at codon 972 (G972R) (rs1801278) in the IRS-1 gene has been associated with impaired insulin action. Another SNP rs2943641 in the IRS-1 gene has been found to be associated with T2DM and insulin resistance in genome-wide association studies. The aim of the present study was to evaluate whether rs1801278 and rs2943641 are associated with increased risk of T2DM in the Saudi population. The study included 376 T2DM cases and 380 healthy controls. Genomic DNA was isolated using a commercially available kit supplied by Norgen Biotech Corp. Genotyping was performed by PCR and RFLP analysis. There was a significant difference in the genotypic distribution as well as allelic frequency between the T2DM cases and controls in case of both the polymorphisms for rs1801278 (1.752, 95 % CI 1.002–3.121; p = 0.04), and for rs2943641 (OR = 1.482, 95 % CI 1.176–1.867; p = 0.001). In conclusion, both the (rs1801278 and rs2943641) polymorphisms are associated with T2DM in the Saudi population. © 2014, Springer Science+Business Media New York. Source
