Term Translation disambiguation in Cross-Language Information Retrieval (Case Study: Translation From Arabic To English)

ABSTRACT Cross-language information retrieval (CLIR), where queries and documents are in different languages, become one of the major topics within the information retrieval community. The important step in CLIR is the translation. This research proposes a term translation disambiguation method based on co-occurrence statistics for translation in Arabic-English CLIR. There are multiple ways to perform query translations: employing machine translation techniques, using parallel corpora or usi...

Assessment Of Plasma Ureacreatinine And Uric Acid Levels Among Sudanese Cigarette Smokers (Study In Khartoum) State

Abstract This is a case-control study, conducted to determine the effect of cigarettes smoking on urea, creatinine and uric acid levels in Sudanese male cigarette smokers in a period from March to May 2015. Eighty samples were collected from cigarette smokers without diseases that may affect levels of urea, creatinine and uric acid. And fifty nonsmokers people as control were informed about study and informed consent for participation was obtained. 2.5 ml of venous blood was collected ...

Spatio-Temporal Variability Of Trace Metals In Atmospheric Fine Particulate Matter From Selected Industrial Sites In Ogun State, Nigeria

   ABSTRACT The spatial and temporal variations of fine particulate matter bound trace metals were investigated in three industrial estates namely Ota Industrial Estate (OTE), Ewekoro Community (EWC) and Agbara Industrial Estate (AGE) and one background (Covenant University Farm Ota) in Ogun State. The sampling period was six (6) months covering the wet and dry seasons. One hundred and fifty (150) samples were collected according to standard methods using environtech gravimetric sampler, a...

A Software Product Line Approach To Ontology-Based Recommendations In E-Tourism Systems

ABSTRACT This study tackles two concerns of developers of Tourism Information Systems (TIS). First is the need for more dependable recommendation services due to the intangible nature of the tourism product where it is impossible for customers to physically evaluate the services on offer prior to practical experience. Second is the need to manage dynamic user requirements in tourism due to the advent of new technologies such as the semantic web and mobile computing such that etourism systems...

An Ant Colony Optimisation Algorithm For Timetabling Problem

 ABSTRACT The University Course Timetabling Problem (UCTP) is a combinatorial optimization problem which involves the placement of events into timeslots and assignment of venues to these events. Different institutions have their peculiar problems; therefore there is a need to get an adequate knowledge of the problem especially in the area of constraints before applying an efficient method that will get a feasible solution in a reasonable amount of time. Several methods have been applied to s...

Evaluation Of Performance Of The SPECT Camera In Elnilien Medical Diagnostic Centre In Khartoum

Abstract The objective of this study is to evaluate the performance of the SPECT gamma camera at Alnilien Medical Diagnostic Centre of Khartoum This study was carried out in Nuclear Medicine Department in Alnelein Medical Diagnostic Centre (NMDC) and the results were compared with the international guidelines. The study evaluates the following parameters: energy resolution, uniformity, sensitivity and linearity All results that obtained from the study have been compared with the accepta...

Location-Allocation-Routing Approach To Solid Waste Collection And Disposal

ABSTRACT Various studies have indicated that the collection phase of solid wastes, which comprises of the initial col- lection at the source of generation and the transportation to the disposal sites, is by far the most expensive. Two fundamental issues of concern in solid waste collection are the locations of initial collection and the period of collection by the dedicated vehicles. However, considering the prevailing conditions of adhoc lo- cation of waste containers and the faulty roads in...

Analytical Study And Generalisation Of Selected Stock Option Valuation Models

ABSTRACT In this work, the classical Black-Scholes model for stock option valuation on the basis of some stochastic dynamics was considered. As a result, a stock option val- uation model with a non-_xed constant drift coe_cient was derived. The classical Black-Scholes model was generalised via the application of the Constant Elasticity of Variance Model (CEVM) with regard to two cases: case one was without a dividend yield parameter while case two was with a dividend yield parameter. In both ...

Growth And Characterization Of Ternary Chalcogenide Thin Films For Efficient Solar Cells And Possible Industrial Applications

ABSTRACT   Ternary thin films of Iron Copper Sulphide (FeCuS), Iron Zinc Sulphide (FeZnS), Lead Silver Sulphide (PbAgS), Copper Silver Sulphide (CuAgS) and Copper Zinc Sulphide (CuZnS) were grown using cheap and simple solution growth technique with EDTA, TEA and NH3 as complexing agents. The deposited films were characterized using PYE-UNICO-UV-2102 PC spectrophotometer, and optical microscopy. The results suggest that some of the films have crystal structures. From the spectral analysis ...

Assay Of Antibiotic Producing Microorganisms From Different Soils In The Premises Of Federal University Oye-Ekiti, Ekiti St A Te. (Fuoye)

ABSTRACT A total of eight soil samples were collected from different sites within FUOYE environment and were analyzed to determine the presence of antibiotic producing bacteria, fungi and actinomycete Using nutrient agar, sabauraud dextrose agar and glycerol yeast extract agar as culture media. Seven bacteria: Escherichia coli, Bacillus spp, Pseudomonas spp, Azomonas spp, Gluconobacter spp, Micrococcus spp, and Staphylococcus aureus; five fungi: Rhizopus spp, Mucor spp, Rhodotorula spp, ...

Delineation Of Anisotropy Properties Of Fracture In Part Of Federal University Oye-Ekiti Campus Southwestern Nigeria, Using Radial Vertical Electrical Sounding (Rves) Method

ABSTRACT Electrical resistivity survey was used to investigate the anisotropic properties with the view of understanding the major direction of fractures as well as the behavioural patterns of the structures in part of Federal University Oye Ekiti, south western Nigeria. The area lies within the south-western Basement complex of Nigeria underlain by migmatite, granite gneiss. Five Radial Vertical Electrical Soundings (RYES) were carried out along four different azimuths (0°, 45°, 90°...

A Modified Framework for No-Reference Digital Image Quality Assessment

ABSTRACT In light of the information revolution and rapid technological jumps which caused to increase use the digital images to develop large applications in visual communication systems, the target image is typically degraded from an original perfect quality image is called the reference image. Image quality assessment (IQA) is a measure to assess the quality of an image in understanding or in reference to the original image. May occur degradations in image quality during reproduction, tra...

Rainfall Forecasting in Sudan Using Computational Intelligence

Abstract Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time at a given location. Human kind has attempted to predict the weather since ancient times. Generating predictions of meteorological events is very complex process, because the atmosphere is unstable and the systems responsible for the events are the culmination of the instabilities and involve nonlinear interaction between different spatial scales from kilometers ...

Assessment of Plasma Urea and Creatinine levels among Sudanese Children using Antiepileptic Drugs in Khartoum state

Abstract Background and Aim of the study: antiepileptic drugs such as valproic acid (VPA) and carbamazepine (CBZ) may disrupt renal function. Plama Urea and creatinine may reflect renal dysfunction and may be useful in detecting renal injury. The aim of this study was to determine the levels of plasma urea and creatinine in Sudanese children used antiepileptic drugs (CBZ and VPA). Materials and Methods: this was cross sectional comparative study, conducted from May to September 2019, at Soba...
