<P><B>Abstract</B></P> <P>Interoperability remains a major burden to the developers of Internet of Things systems. It is due to IoT devices are extremely heterogeneous regarding basic communication protocols, data formats, and technologies. Furthermore, due to the absence of worldwide satisfactory standards, Interoperability tools remains imperfect. In this paper, we have proposed Semantic Interoperability Model for Big-data in IoT (SIMB-IoT) to deliver semantic interoperability among heterogeneous IoT devices in health care domain. This model is used to recommend medicine with side effects for different symptoms collected from heterogeneous IoT sensors. Two datasets are taken for the analysis of big-data. One dataset contains diseases with drug details and the second dataset contains medicines with side effects. Information between physician and patient are semantically annotated and transferred in a meaningful way. A Lightweight Model for Semantic annotation of Big-data using heterogeneous devices in IoT is proposed to provide annotations for big data. Resource Description Framework (RDF) is a semantic web framework that is recycled to communicate things using Triples to make it semantically significant. RDF annotated patients’ data and made it semantically interoperable. SPARQL query is used to extract records from RDF graph. Tableau, Gruff-6.2.0, and Mysql tools are used in simulation in this article.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A Lightweight SIMB-IoT model is proposed for heterogeneous IoT devices for semantic interoperability in healthcare domain. </LI> <LI> Intelligent health cloud recommends drugs and their side effects against the input of different diseases’ symptoms. </LI> <LI> Semantic data analytics is used to expose hidden patterns from a large volume of the big dataset. </LI> <LI> SPARQL is used to interact with the document, indexed by MedDRA repository’s keywords. </LI> </UL> </P>

Intelligent Clustering in Vehicular ad hoc Networks

( Farhan Aadil ),( Salabat Khan ),( Khalid Bashir Bajwa ),( Muhammad Fahad Khan ),( Asad Ali ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.8

A network with high mobility nodes or vehicles is vehicular ad hoc Network (VANET). For improvement in communication efficiency of VANET, many techniques have been proposed; one of these techniques is vehicular node clustering. Cluster nodes (CNs) and Cluster Heads (CHs) are elected or selected in the process of clustering. The longer the lifetime of clusters and the lesser the number of CHs attributes to efficient networking in VANETs. In this paper, a novel Clustering algorithm is proposed based on Ant Colony Optimization (ACO) for VANET named ACONET. This algorithm forms optimized clusters to offer robust communication for VANETs. For optimized clustering, parameters of transmission range, direction, speed of the nodes and load balance factor (LBF) are considered. The ACONET is compared empirically with state of the art methods, including Multi-Objective Particle Swarm Optimization (MOPSO) and Comprehensive Learning Particle Swarm Optimization (CLPSO) based clustering techniques. An extensive set of experiments is performed by varying the grid size of the network, the transmission range of nodes, and total number of nodes in network to evaluate the effectiveness of the algorithms in comparison. The results indicate that the ACONET has significantly outperformed the competitors.

Farhan Istesham,Husnia Khaliqa Sumaita,Phillip Pardo Academy of Asian Business (AAB) 2022 Academy of Asian Business Review Vol.8 No.2

The case study provides an in-depth analysis of how ShopUp has enabled MSMEs to develop and function steadily, creating vast scopes for the retail industry of Bangladesh. Targeting its activities toward the most unorganized retail sector of the Asian market, where small businesses lack technological expertise for e-business management, capital or loan procurement methods, credible sourcing products or active delivery chains, ShopUp has managed to become the top B2B e-commerce platform of the country. Therefore, the case deconstructs the service infrastructure of ShopUp and uncovers how it moved through the development timeline, transforming from a credit provider into a unique and diversified service provider that boosted the lagging retail industry’s performance by integrating f-commerce into its operations. Following this, the study identifies the major turning points in ShopUp's journey and how it converted external challenges into market opportunities. The case then delves into ShopUp’s success factors and highlights how the company’s efficient leadership team fostered relevant partnerships and focused on vertical expansions. The final section examines ShopUp’s existing issues and suggests potential alternatives to overcome the constraints imposed by those challenges. Overall, the case study demonstrates how a company may use innovative technology to expand customer scope and redefine corporate growth.

Wakes of two inline cylinders at a low Reynolds number

Farhan Zafar,Md. Mahbub Alam,Zaka Muhammad,Md. Islam 한국풍공학회 2019 Wind and Structures, An International Journal (WAS Vol.29 No.1

The effect of vortex impingement on the fluid dynamics around a cylinder submerged in the wake of another of different diameters is numerically investigated at a Reynolds number Re = 200. While the diameter (D) of the downstream cylinder is fixed, impinging vortices are produced from the upstream cylinder diameter (d) varied as d/D = 0.24, 0.4, 0.6, 0.8 and 1.0, with a spacing ratio L = 5.5d, where L is the distance between the center of the upstream cylinder to the front stagnation point of the downstream cylinder. Two-dimensional simulations are carried out using the finite volume method. Fluid forces acting on the two cylinders are correlated with impinging vortices, vortex shedding, and wake structure. Different facets of wake formation, wake structure, and flow separation and their connections to fluid forces are discussed.

White sesame seed oil (WSSO) has been used in cooking and food preparations for centuries. It has many purported health benefits and may be a promising nutraceutical. The primary purpose of this study was to examine the effects of WSSO on fasting blood glucose (GLU) and insulin (INS) in male Sprague-Dawley rats with chemically induced diabetes. A secondary aim was to explore other hematological biomarkers of hepatic, cardiac, and renal function. Sixty-three male Sprague-Dawley rats were randomized into standard diet groups, normal control (NCON) (n = 21) and diabetic control (DCON) (n = 21), and a diabetic sesame oil (DSO) (n = 21) group, which were fed a diet containing 12% WSSO. Blood samples were analyzed at 0, 30, and 60 days. Differences between groups and across days were assessed with two-way repeated measures analysis of variance. At baseline, GLU and INS were similar in both diabetic groups, mean 248.4 ± 2.8 mg/dL and mean 23.4 ± 0.4 μU/mL, respectively. At 60 days, GLU was significantly (P < .05) higher in DCON (298.0 ± 2.3 mg/dL) compared with DSO (202.1 ± 1.0 mg/dL). INS showed similar favorable trends after WSSO supplementation. Consumption of WSSO significantly improved glucose control and other biomarkers of hepatic stress, as well as cardiac and renal health. WSSO may be a viable functional food to help reduce the detrimental effects of diabetes.

Farhan Aadil,Zeshan Iqbal,Adeel Akram 한국산학기술학회 2012 SmartCR Vol.2 No.6

Vehicular communication systems are a key part of an intelligent transportation system, while vehicle safety communication is a major target of vehicular communication. Other features that augment vehicular ad hoc networks are enhanced driving experience, including but not limited to, active navigation and weather information, real-time traffic information and a plethora of other autonomous and automated systems. However, our focus will be warning generation systems, which can help reduce fatalities if deployed in an efficient and fail-safe manner on motorways and highways. This paper describes a collective information system for collection and delivery of traffic information aimed at supporting fast, efficient and secure travel of people and transport of goods. Based on that information, authorities are able to assess vehicles’ sudden motion and movement changes and can generate warning/alert messages (for emergency/police vehicles) for post-accident scenarios. In this paper, the use of a radio frequency identification (RFID) system for vehicular communication has been proposed and an extended RFID system and infrastructure for vehicle safety communication through emergency phone towers (EPTs) and cell phones is suggested. In order to communicate, vehicles may be equipped with a cellular phone, RFID, and/or a global positioning system (GPS), whereas RFID readers may be mounted on EPTs, which are already installed on motorways. It also provides a demonstration on flow of information within the system; the simulation results are also included.

PURPOSE To compare the changes in the occlusal vertical dimension, activity of masseter muscles and biting force after insertion of immediate denture constructed with conventional, tooth-supported and Implant-supported immediate mandibular complete denture. MATERIALS AND METHODS Patients were selected and treatment was carried out with all the three different concepts i.e, immediate denture constructed with conventional (Group A), tooth-supported (Group B) and Implant-supported (Group C) immediate mandibular complete dentures. Parameters of evaluation and comparison were occlusal vertical dimension measured by radiograph (at three different time intervals), Masseter muscle electromyographic (EMG) measurement by EMG analysis (at three different positions of jaws) and bite force measured by force transducer (at two different time intervals). The obtained data were statistically analyzed by using ANOVA-F test at 5% level of significance. If the F test was significant, Least Significant Difference test was performed to test further significant differences between variables. RESULTS Comparison between mean differences in occlusal vertical dimension for tested groups showed that it was only statistically significant at 1 year after immediate dentures insertion. Comparison between mean differences in wavelet packet coefficients of the electromyographic signals of masseter muscles for tested groups was not significant at rest position, but significant at initial contact position and maximum voluntary clench position. Comparison between mean differences in maximum biting force for tested groups was not statistically significant at 5% level of significance. CONCLUSION Immediate complete overdentures whether tooth or implant supported prosthesis is recommended than totally mucosal supported prosthesis.

Survey of Automatic Query Expansion for Arabic Text Retrieval

Farhan, Yasir Hadi,Noah, Shahrul Azman Mohd,Mohd, Masnizah Korea Institute of Science and Technology Informat 2020 Journal of Information Science Theory and Practice Vol.8 No.4

Information need has been one of the main motivations for a person using a search engine. Queries can represent very different information needs. Ironically, a query can be a poor representation of the information need because the user can find it difficult to express the information need. Query Expansion (QE) is being popularly used to address this limitation. While QE can be considered as a language-independent technique, recent findings have shown that in certain cases, language plays an important role. Arabic is a language with a particularly large vocabulary rich in words with synonymous shades of meaning and has high morphological complexity. This paper, therefore, provides a review on QE for Arabic information retrieval, the intention being to identify the recent state-of-the-art of this burgeoning area. In this review, we primarily discuss statistical QE approaches that include document analysis, search, browse log analyses, and web knowledge analyses, in addition to the semantic QE approaches, which use semantic knowledge structures to extract meaningful word relationships. Finally, our conclusion is that QE regarding the Arabic language is subjected to additional investigation and research due to the intricate nature of this language.
