Analytical Algorithms for Ergonomic Seated Posture When Working with Notebook Computers
Jalil, Sakib,Nanthavanij, Suebsak Korean Institute of Industrial Engineers 2007 Industrial Engineeering & Management Systems Vol.6 No.2
This paper discusses two algorithms for recommending notebook computer (NBC) and workstation adjustments so that the user can assume an ergonomic seated posture during NBC operation. Required input data are the user's anthropometric data and physical dimensions of the NBC and the workstation. The first algorithm is based on an assumption that there are no workstation constraints while the second algorithm considers the actual seat height and work surface height. The results from the algorithms include recommendations for adjusting the NBC (tilt angle of the NBC base unit, angle between the base and screen units, and base support height) and the workstation (heights of seat support and footrest, and distance between the body and the NBC).
Fuzzy-Based Sensor Fusion for Cognitive Radio-Based Vehicular Ad Hoc and Sensor Networks
Jalil Piran, Mohammad,Ali, Amjad,Suh, Doug Young Hindawi Limited 2015 Mathematical problems in engineering Vol.2015 No.-
<P>In wireless sensor networks, sensor fusion is employed to integrate the acquired data from diverse sensors to provide a unified interpretation. The best and most salient advantage of sensor fusion is to obtain high-level information in both statistical and definitive aspects, which cannot be attained by a single sensor. In this paper, we propose a novel sensor fusion technique based on fuzzy theory for our earlier proposed Cognitive Radio-based Vehicular Ad Hoc and Sensor Networks (CR-VASNET). In the proposed technique, we considered four input sensor readings (antecedents) and one output (consequent). The employed mobile nodes in CR-VASNET are supposed to be equipped with diverse sensors, which cater to our antecedent variables, for example, The Jerk, Collision Intensity, and Temperature and Inclination Degree. Crash_Severity is considered as the consequent variable. The processing and fusion of the diverse sensory signals are carried out by fuzzy logic scenario. Accuracy and reliability of the proposed protocol, demonstrated by the simulation results, introduce it as an applicable system to be employed to reduce the causalities rate of the vehicles’ crashes.</P>

Introduction: Kelantan is one of the states in Malaysia which has a high prevalence of type 2 diabetes (DM2). Other than with endometrial carcinoma, the association of DM2 with particular female cancers is not known. Objective: To determine the proportion of breast, cervical, ovarian and endometrial cancers among females with DM2 diagnosed in Hospital Universiti Sains Malaysia (HUSM) over an 11 year period. Materials and Methods: All histologically confirmed cases of breast, endometrial, cervical and ovarian carcinomas admitted to the Hospital were included in the study. The patient diabetic status was traced from the hospital medical records. Results: There was a total of 860 cases of breast, cervical, ovarian and endometrial carcinomas over this period. Breast carcinoma was the commonest, accounting for 437/860 (50.8%) followed by cervix, 159/860 (18.5%), ovarian, 143/860 (16.6%) and endometrial carcinomas, 121/860 (14.1%). Out of these, 228/860 (26.5%) were confirmed diabetics. Endometrial carcinoma patients showed the highest proportion being diabetics, 42.1% (51/121), followed by ovarian cancer, 25.9% (37/143), breast carcinoma, 23.6% (103/437) and cervical cancer 23.3% (37/159). Conclusions: There is a significant proportion of DM2 among women with these four cancers, endometrial carcinoma being the highest followed by ovarian, breast and cervical carcinoma. The rising trend of these four cancers is in tandem with an increasing trend of DM2 in the community. In populations where diabetes is prevalent, screening for epithelial cancers should be rigourous. Diabetic clinics should include screening for these cancers among their female patients and gynecology clinics should screen the women they treat for their diabetes status.
Evaluation of Islamic Banking Efficiency in Iran
Jalil Khaksar,Mahdi Salehi,Elahe Torabi 동아시아경상학회 2014 The East Asian Journal of Business Economics Vol.2 No.2
Purpose - In this study, it is attempted to examine the Islamic banking practice in Iran based on new scientific methods. Design/methodology/approach- It is used the financial ratios demonstrating healthy or non-healthy of banks to assess the financial health of listed banks in Tehran Stock Exchange. The assessment of these ratios with use of decision tree as a non-parametric method for modeling is recommended for presenting this model. Information about the financial health of banks could be effective on the decisions of different groups of banks financial reports users, including shareholders, auditors, stock exchange, central bank and etc. Findings - the results of the study show that Decision Tree is strong approach in order to classifying Islamic banks in Iran. Originality/value- So far, several studies have been conducted in various countries on the topic of this study. Considering the importance Islamic banking, it is almost the first study in Iran and the outcomes of the study may helpful to Iranian economy.

The development and design of adsorbents with high adsorption performance is an effective method of removing p-Cresol from effluent for environmental protection. Therefore, an Al2O3 coated multiwalled carbon nanotubes (MWNTs) composite for adsorption of p-Cresol from aqueous solution was synthesized. The p-Cresol concentration was determined by estimating the absorbance of the sample solution on a DR5000 UV/vis spectrophotometer. Box–Behanken design (BBD) was involved in the optimization of p-Cresol adsorption upon Al2O3 coated MWNTs adsorbent against the process parameters time, pH and adsorbent dose. The effects of these factors were studied in the ranges 5–40 min, 4–10, and 0.2–2 g L−1, respectively. The lack of fit obtained for this model was 0.357 which confirmed that the model is highly significant and the experiments are accurate and reliable. The results showed that adsorption isotherms fit well with the pseudo-second-order kinetic model and Langmuir isotherm model and Qmax was calculated to be 54.05 mg/g. Our results demonstrate that Al2O3 coated MWNTs has the potential to be used as an effective adsorbent for the rapid uptake of p-Cresol from aqueous solutions.
Determining PGAA collimator plug design using Monte Carlo simulation
Jalil, A.,Chetaine, A.,Amsil, H.,Embarch, K.,Benchrif, A.,Laraki, K.,Marah, H. Korean Nuclear Society 2021 Nuclear Engineering and Technology Vol.53 No.3
The aim of this work is to help inform the decision for choosing a convenient material for the PGAA (Prompt Gamma Activation Analysis) collimator plug to be installed at the tangential channel of the Moroccan Triga Mark II Research Reactor. Two families of materials are usually used for collimator construction: a mixture of high-density polyethylene (HDPE) with boron, which is commonly used to moderate and absorb neutrons, and heavy materials, either for gamma absorption or for fast neutron absorption. An investigation of two different collimator designs was performed using N-Particle Monte Carlo MCNP6.2 code with the ENDF/B-VII.1 and MCLIP84 libraries. For each design, carbon steel and lead materials were used separately as collimator heavy materials. The performed study focused on both the impact on neutron beam quality and the neutron-gamma background at the exit of the collimator beam tube. An analysis and assessment of the principal findings is presented in this paper, as well as recommendations.
