Apprendre à exploiter la houillère
Authors: Rojas Luc 
Published: November 2020

L’extraction du charbon de terre représente durant le XIX e siècle et le premier tiers du XX e siècle un enjeu économique important. L’instruction technique des futurs exploitants devient un moyen de favoriser le développement industriel du pays. Cependant, les savoirs transmis ne sont pas de même nature d’une période à l’autre. En effet, les cours dispensés au sein des écoles d’ingénieurs évoluent considérablement passant de la simple description technique de machines et de méthodes à des savoirs prenant en compte les dimensions techniques, économiques et sociales d’une mine. Finalement ces enseignements proposent, durant l’entre deux guerres, aux futurs exploitants de gérer la technique comme une ressource et un capital pour l’entreprise loin de la vision positiviste, magnifiant le culte de la science et de la perfection technique, développée par Auguste Comte et véhiculée par les cours du début du XIX e siècle.
Révéler ce qui fait patrimoine pour penser le renouvellement urbain des cités d’habitations à bon marché de Grenoble
Authors: Hadbi Ryma 
Published: November 2020

Ce projet de recherche consiste à questionner ce qui fait patrimoine dans trois cités d’habitations à bon marché de Grenoble construites dans les années 1920-1930 : les cités de la Capuche, l’Abbaye et Jean Macé. À l’origine similaires dans leur contexte de construction, ces dernières ont connu des transformations architecturales, urbaines et sociales différentes au fil du temps. Ce qui fait patrimoine est abordé, ici, comme un processus vivant qui sans cesse évolue, intègre des mutations, des changements, des ruptures et qui articule trois valeurs patrimoniales conjointes : valeur historique, valeur d’usage et valeur de renouvellement. Pour cela, nous nous intéressons aux mémoires individuelles et collectives, aux usages et aux récits de vie des personnes qui ont habité ces cités depuis des décennies. Ce qui compte, c’est en fin de compte la valeur que l’on accorde aux habitants et à leurs attaches. Tout autant, ce travail démontre l’intérêt de penser ce qui fait patrimoine par l’attachement au lieu pour penser le renouvellement urbain de ces cités pleines de significations affectives. La mémoire urbaine serait un moyen de lire à la fois le passé, le présent et le devenir possible d’un site en postulant qu’elle détient en quelque sorte les « gènes » du lieu. Elle serait l’héritage, le bien commun à partir duquel pourrait se faire tout renouvellement de ces lieux riches en mémoires et en émotions.

Physicochemical properties and antibiotic susceptibility of microorganisms isolated from wastewater samples collected from Al-Hikmah University female hostels were assessed. Samples obtained from different female hostels were examined physiochemically and microbiologically using standard procedures. Phytochemical result revealed the low temperature value of 28°C from Oladimeji and Commaissie hostels, while Deremi and Owaish had a value of 29.5°C. Dissolved oxygen of 0.1 ml/L was recorded from all the samples collected. Electrical conductivity ranged from 658 to 997µs, while chocking odour was recorded in all the four samples collected. In terms of pH, Oladimeji hostel had a pH of 10.5, Deremi had a pH of 10.6, while Owaish and Commaissie had a pH of 10.4. The wastewater samples from the four hostels were highly contaminated. Oladimeji hostel showed a mean bacterial 5count of 25.4×10cfu/ml, Deremi hostel, Owaish hostel and Coomassie hostels, showed a mean 4 4 4bacterial count of 5.7×10cfu/ml,16.8×10cfu/ml and 3.5×10cfu/ml respectively. Percentage occurrence of bacteria isolates were Salmonella sp. (12.5%), Klebsiella pneumoniae (12.5%), Escherichia coli (25%), Staphylococcus aureus (12.5%), Actinomyces (12.5%), Shigella sp. (6.25%), Pseudomonas aeruginosa (12.5%) and Proteus vulgaris (6.25%). Antimicrobial sensitivity tests revealed that all the organisms were susceptible to gentamycin except Actinomyces.

Authors: Al-Khalidi Mohammed Taher , Al-Marzook Misk , Hassan Zainab 
Published: November 2020

Background
Hepatitis B and C are infectious diseases caused by the hepatitis B Virus (HBV) and C virus respectively, that affects the liver. Hepatitis viruses are transmitted by blood-to-blood contact associated with dialysis, poorly sterilized medical equipment, needle-stick injuries, blood transfusion, and intravenous drug users.
Methods
this is a cross-sectional study conducted in the Hemodialysis Unit of Baghdad Teaching Hospital between the period of April and September 2018. Ninety-eight patients were enrolled in this study after adopting informed consent.
All patients were on regular hemodialysis as a renal replacement therapy with different durations. Full history was taken from them including age, gender, occupation, marital status, and past medical and surgical histories. Blood test results were also recorded. all data were analyzed using SPSS20 with 95%confidence which means a p-value less than 0.05 to be statistically significance.
Results
The percentage of Hemodialysis patients infected with Hepatitis C was (43%) while those infected with Hepatitis B was (3%). There is no statistically significant association between age and infection with Hepatitis B & C (P>0.05). The mean age of patients infected with Hepatitis B was (65.8±8.2), while for patients infected with Hepatitis C it was (45.3±14.7).
Conclusion
Hepatitis C is more prevalent than Hepatitis B in the Hemodialysis Unit and the infection was not statistically associated with the age or gender of the patients
Thalassemia prevention program in Iraq: Will it be cost-effective and applicable?
Authors: Majid Mustafa , Mutar Mohammed 
Published: November 2020

Thalassemia is an inherited autosomal recessive hemoglobinopathy which has a prevalence of 35.7/100000 and incidence of 4.5 per 100000 in Iraq. The disease is totally preventable as many countries succeeded in accomplishing this. Many domains included in the prevention program ranging from education, carrier detection, molecular diagnosis, genetic counselling prenatal diagnosis and therapeutic abortion. The last option may find difficulties in its accomplishment in Arabic countries as it finds contradictions to some religious and tradition habits.
In Iraq it does cause burden on health budget as a report from the federal board of supreme audit in 2016 revealed that the cost of management of each patient is 1428.00-3785.00 US$/month, this include blood transfusion, drugs and other treatment facilities. As this calculated for the life expectancy for thalassemic major patient and number of patients in Iraq, the pattern of Burden will be identified clearly. Comparing this pattern to that of single case prevention calculations may show the cost effectiveness of thalassemia prevention.
The aim of this study is to assess the cost-effectiveness of applying a prevention program and the difference in expenditure between case prevention and management per year and to see the extent of applicability of the prevention program.

Authors: Theofilatos K. , Likothanassis S. , Karathanasopoulos A. 
Published: November 2020

The present paper aims in investigating the performance of state-of-the-art machine learning techniques in trading with the EUR/USD exchange rate at the ECB fixing. For this purpose, five supervised learning classification techniques (K-Nearest Neighbors algorithm, Naïve Bayesian Classifier, Artificial Neural Networks, Support Vector Machines and Random Forests) were applied in the problem of the one day ahead movement prediction of the EUR/USD exchange rate with only autoregressive terms as inputs. For comparison reasons, the performance of all machine learning techniques was benchmarked by two traditional techniques (Naïve Strategy and moving average convergence/divergence model). Trading strategies produced by the machine learning techniques of Support Vector Machines and Random Forests clearly outperformed all other strategies in terms of annualized return and sharp ratio. To the best of our knowledge, this is the first application of Random Forests in the problem of trading with the EUR/USD exchange rate providing extremely satisfactory results.

Coplanar Stripline Loaded Reconfigurable Loop Antenna for WLAN and WiMAX Applications
Authors: Shastri S. P. R. , Singh R. R. , Ajetrao K. V. 
Published: November 2020

In this paper, a loop antenna loaded with coplanar strip (CPS) line is proposed as a multiband antenna. The CPS line is added with two switches to vary the antenna perimeter to cover seven different bands. The CPS line introduced into the loop is not only useful in reconfiguring antenna dimensions but also provides stationary radiation patterns for the all the covered bands. The proposed antenna works in single and dual-band modes. When the proposed antenna works as a single band antenna, it produces a band from 4.2GHz to 5.7GHz. Under dual-band operation, it produces bands from 3.75GHz to 4.7GHz and from 6.4GHz to 7.8GHz. The other dual-band mode ranges from 3.5GHz to 3.8GHz and from 5.58GHz to 7.4 GHz. The simulated and measured results are in good agreement and the proposed antenna can be used satisfactorily for W-LAN and WiMax applications. The proposed technique can also be used for size reduction of loop antennas.
Investigating the Effect of Ramp Geometry on the Flow Characteristics Around Under Pressure Tunnel Aerator Using OpenFoam Open Source Software
Authors: Manafpour M. , Ebrahimnezhadian H. 
Published: November 2020

The flow around the ramp embedded in a pressurized tunnel is divided into various zones downstream of the ramp, including the cavity and the main zone of flow above the shear layer. Ramp angle and height are parameters that affect the flow characteristics such as cavity length, velocity, and pressure coefficient immediately downstream of the ramp. In this study, OpenFOAM open source software and RNG K-ε turbulence model were used to simulate the flow around the under pressure tunnel ramp. In order to investigate the effect of the ramp geometry on the flow in various relative air discharges 0<β<10, the range of height and the angle of the ramp as 5<θ<20 and 0.1<tr/d<0.4 were developed and simulated. The correlation coefficient between the numerical and experimental results for the relative cavity length is in the range of 0.9377≤R2≤0.9722 that indicates proper agreement between results. The result of the research shows that in both cases of fixed height of ramp and increasing ramp angle, and fixed angle of the ramp and increasing ramp height, the values of the cavity length and maximum turbulence intensity increase, and the minimum pressure values at the cavity zone bed are decreased. But in both cases, the sensitivity of the three mentioned parameters is higher than the ramp height increment.
Residential Buildings Thermal Performance to Comply With the Energy Conservation Code of Saudi Arabia
Authors: AlFaraidy F. A. , Azzam S. 
Published: November 2020

About half of the total generated electricity in Saudi Arabia (SA) is consumed for the air conditioning of residential buildings. To reduce this burden on the economy as outlined by the country's 2030 vision, the implementation of the Saudi energy conservation code (SBC602) needs to be enforced. This code divided KSA into three climate zones with maximum overall heat transfer coefficients. This study aims to facilitate the use of thermal insulation by analyzing optimum thermal insulation thickness for each zone and calculate the payback period of initial insulation costs. Three cities were selected to represent the three climate zones, Riyadh, Arar, and Turaif. The code-compliant thermal insulation thickness is calculated using these variables: thermal properties of three insulation materials, overall heat transfer coefficients, and three insulated wall structures. It is concluded that external insulation and finish system utilizing polyurethane is the most feasible option with the best thermal performance. Polyurethane thicknesses are ranging from 45mm to 65mm, wall widths are ranging from 250mm to 320mm, while the overall costs are ranging from 20.02 to 24.57 US$/m2. This system is used to conduct a comparison between energy-efficient-building and base-case-building in terms of cooling loads and electrical consumption using hourly-analysis-program (HAP) with international weather data. The simulated annual savings in energy consumption for the three zones are 67.4%, 66.56%, and 67.91%. The economic analysis shows promising payback years, which are 3.1, 3.9, and 4.3 for zone one, zone two and zone three respectively.
Knowledge-Based Method for Word Sense Disambiguation by Using Hindi WordNet
Authors: Sharma P. , Joshi N. 
Published: November 2020

The purpose of word sense disambiguation (WSD) is to find the meaning of the word in any context with the help of a computer, to find the proper meaning of a lexeme in the available context in the problem area and the relationship between lexicons. This is done using natural language processing (NLP) techniques which involve queries from machine translation (MT), NLP specific documents or output text. MT automatically translates text from one natural language into another. Several application areas for WSD involve information retrieval (IR), lexicography, MT, text processing, speech processing etc. Using this knowledge-based technique, we are investigating Hindi WSD in this article. It involves incorporating word knowledge from external knowledge resources to remove the equivocalness of words. In this experiment, we tried to develop a WSD tool by considering a knowledge-based approach with WordNet of Hindi. The tool uses the knowledge-based LESK algorithm for WSD for Hindi. Our proposed system gives an accuracy of about 71.4%.
Simulation and RTDS Hardware Implementation of SHAF for Mitigation of Current Harmonics with p-q and Id-Iq Control Strategies Using PI Controller
Authors: Mikkili S. , Panda A. K. 
Published: November 2020

Control strategies for extracting the three-phase reference currents for shunt active power filters are compared, evaluating their performance under different source conditions in MATLAB/Simulink environment and also with Real Time Digital Simulator (RTDS) Hardware. When the supply voltages are balanced and sinusoidal, the two control strategies are converging to the same compensation characteristics but when the supply voltages are distorted and/or un-balanced sinusoidal, these control strategies result in different degrees of compensation in harmonics. The p-q control strategy is unable to yield an adequate solution when source voltages are not ideal. Extensive Simulations are carried out with PI controller for both p-q and Id-Iq control strategies for different voltage conditions and adequate results were presented. The 3-ph 4-wire SHAF system is also implemented on RTDS Hardware to further verify its effectiveness. The detailed simulation and RTDS Hardware results are included.
