An identifying event in sports video has many efforts of sports applications. In this paper, proposed a system for automatic detection of key events in Broadcast Tennis Video (BTV). The ultimate goal is to detect the events of complete tennis match. The detected tennis events are fault, rally and net approach, there are also other events in BTV, they all are considered as secondary one. To detect the events of tennis by analyzing the player`s position and ball tracking. The experiments done in different tennis tournament, which has the events (fault, rally and net approach), the some of the visual features are extracted from MHI (Motion History Image) and modelled by Support Vector Machines (SVM) and Hidden Markov Model (HMM) for recognizing tennis events. In result HMM gives a higher accuracy rate of 96.66% when compared to SVM rate of 86.42%.

La RD Congo reste toujours un pays en conflits internes et externes. Ce spiral des conflits récurrents détruit l’organisation politique, sociale et économique de l’Est, ils vont jusqu’à affecter les rapports sociaux. Une seule voie reste, la voie de la réconciliation pour rétablir la cohésion Nationale. La manière par la quelle cette réconciliation a été expérimentée dans le processus de la paix témoigne toujours la persistance de conflits. Une telle situation résume qu’il est difficile de construire la paix et penser à un développement harmonieux. Car la RD Congo reste un pays fragile et les vraies motivations pour gérer la république dans le plan de la Justice, de la vérité, du pardon et de la réconciliation pour la paix durable reste hypothétique au risque d’éclatement des nouvelles violences.

Krukenberg's Tumors (TK) are defined as bilateral ovarian metastases from gastrointestinal cancer most often. They are rare and account 1 to 2% of ovarian tumors. We report a case of Krukenberg gastric original tumor in a female patient of 40 years old, G3P3, 3 living children, thyroidectomized with hormone replacement therapy, she was hospitalized for surgical exploration of two malignant abdominopelvic masses objectified in clinical examination and abdominopelvic ultrasound. Laparotomy had highlighted two ovarian tumors whose histology was in favor of ovarian metastases from carcinoma of digestive origin. Gastroesophageal Endoscopy showed a gastric adenocarcinoma with a signet-ring appearance of the pylorus and bulb gastric. Palliative chemotherapy was indicated. The patient died after four months. The treatment of this tumor remains palliative and is not codified. The progress of chemotherapy could improve the prognosis who is pejorative.

BACKGROUND: Health is wealth. Life is more precious for everyone and health cannot be earned. In the health care organization, the nurse turnover may detract the quality of care. To mitigate such a problem, it is better to examine nurses’ intentions to leave. OBJECTIVES: This study attempts to test the effects of workplace social context and job context and its relationship with the person - organization fit towards turnover intention of nurse’s at multi-speciality hospitals, are the focus of the study. METHODS: A structured survey questionnaire measures the responses from 847 nurses of multi-speciality hospitals using stratified random sampling method. Descriptive analysis, Correlation, and ANOVA were used. Confirmatory Factor Analysis using AMOS 20.0 validated the measurement model. RESULTS: The results show that workplace social context and job context have a positive relationship with the person - organization fit, with r =.233**, r =.284**, and p < .05. In turn, the person - organization fit has a significant negative relationship with intent to leave, as shown by r = -.383**. The χ2 statistics were significant and sensitive to sample size and model complexity. The fit indices were good and showed an acceptable fitting model. CONCLUSION: Job context has a greater impact than workplace social context on turnover intention of nurses through person - organization fit. Job context is closely related to person - organization fit. Higher the person - organization fit lowers the intent to leave among the nurses in multi-speciality hospitals.

Beta thalassemia major (also known as Cooley's anemia) is an inherited red blood cell disorder that results in the complete absence or decreased synthesis of the beta globin chains of hemoglobin. Beta thalassemia is among the most common genetic diseases in Morocco and characterized by mild to severe anemia, delay of growth and puberty, enlargement of the spleen, cardiac disease and dysmorphic bone changes. Untreated newborns have a higher risk of death within the first two years of life. Aim: The aim of this study is to evaluate the hematological and nutritional profile in young beta-thalassemia major patient in the Rabat commune. Material and Methods: This retrospective study assessed 104 young beta-thalassemia major patient followed at the division of pediatric hematology-oncology, Rabat children’s hospital, Morocco between October 2014 and 30 June 2015. Patients received regular transfusions every three weeks to maintain hemoglobin levels greater than 10 g/dl. To reduce iron overload, chelation therapy was considered to maintain the serum ferritin levels between 800-1000 ng/mL. Epidemiological, clinical and biological data were collected from medical records and transfusion files of patients. Furthermore, evaluation of the nutritional status and anthropometric measures such as weight-for-age and height-for-ageof subjects were investigated. Results: Data from medical records showed that the average age in our cohort is 11.42 years (the youngest age is 6 and the oldest age is 16). Low hemoglobin count (9.70 g/dl ±1.20) indicateda severe anemia which result in an important microcytosis and hypochromia. Indeed, 39.5% of patient developed leukocytosis, 12.5% neutrophilia, 23% eosinophilia, 9.6% basophilie, 85% monocytopenia, and 28% lymphocytosis. The percentage of subjects presenting stunting and wasting were 39.4%and 19.2%, respectively in patients. Conclusion: This study substantiates that beta thalassemia major young patients require a monitoring from birth, life-long transfusion support, reduction of overloaded iron, and regular nutritional assessment to prevent or reduce the risk of hematological and anthropometric complications.

The object of this research is to outline a method of building a measurement scale assessing staff satisfaction Moroccan public administrations. The measures were built from a survey of 237 functionaries in the Casablanca-Settat region. The methodology is based on the steps recommended by the paradigm of Churchill (1979), specifically its exploratory phase based on qualitative approach using semi-structured interviews and quantitative approaches based on exploratory factor analyzes and Cronbach's alpha. This paradigm allows building rigorously instruments standard questionnaire to measure multiple scales. The results reveal a structure of staff satisfaction in 5 components with a total explained variance of 80,25%. Only the first component: Remuneration and career management restores 33,35% of the total variance. The size and skills training was excluded in this exploratory phase, it does not explain enough variance in satisfaction. The analysis of the reliability of the scales of the principal components shows that the items of each scale are correlated and coherent with each other and vary between 0,681 and 0,931. It is the same for the reliability of the total scale of which Cronbach's alpha of 0,841.

The aim of this study is to reveal antioxidant capacity of methanol extract of Origanum haussknechtii aerial parts. The antioxidant capacity of methanol extract were assayed with various methods, metal chelating capacity, DPPH free radical and ABTS radical cation scavenging activity, including total phenolic compound contents by Folin – Ciocalteu reagent (FCR). The obtained results were compared with standard antioxidants such as Ascorbic acid, BHT and EDTA. The methanol extract of O.haussknechtii aerial parts showed free radical scavenging activity similar to that of BHT. Also, this extract exhibited strong ABTS radical cation activity. As a conclusion of this study, the methanol extract of O.haussknechtii has beneficial effects on metal chelating, ABTS radical cation , DPPH radical scavenging abilities and may thus exert protection against oxidative damage.

The rise of wireless sensor networks (WSN) is one of the leading innovations that postures different breed of intrusions, vitality and better performances in the nearing decades. However, in WSN, energy plays a vital role in transmitting data between sources. Also several communication protocols are available in cluster based for energy conservation and it varies depending on its application. Among the routing protocols, LEACH is chosen so that the vitality problem can be minimized. Few enhancements to improve its efficiency and ability to deliver data without packet loss is achieved to a greater extent. Increasing their energy through Solar means will prolong the network lifetime. Different enhanced LEACH protocols are collated to increase node alive rate, packet delivery ratio, and average residual energy, throughputs. The above parameters are derived for the R-LEACH, solar powered R-S-LEACH and SLEEP LEACH. The results are obtained using Network Simulator-2.

In this paper composite convolution operators with weight are introduced on Hilbert space H. Some basic properties for composite convolution operators with weight have been investigated. The characterization of normal, Hermitian and idempotent composite convolution operators with weight are explored. The commutant of composite convolution operators with weight has also been characterized.

Self-esteem has become an essential element of individual success in different life domains: work, social relations, sport, physical appearance, behaviour. However, context plays a particularly important role. This article unveils the role of family context in the structuring of self-esteem. Children brought up by single mothers live in a particular context, where parental identification exhibits quite serious defects coupled with the emotional deprivation of one parent, the father. After correlating self-esteem with age, we got a negative value (-0.117), which shows that the more these children grow, the more self-esteem declines. Yet, the said children already exhibit a low self-esteem with differences that are not significant to sex and age (9-12 years and 13-18 years).

The aim of this paper is to describe a methodology used to create an application that teaches programing to college students. The instructional design model and incremental software development model are used as a base. The instructional design model is a general methodology for the development of educational materials. This methodology is composed by 5 phases: Analysis Design, Development, Implementation and Evaluation, commonly refereed as ADDIE. We use the software incremental methodology, this software methodology divide software development into increments, in each increment, a functional software is developed and can be tested, for each increment will use the 5 phases of instructional design presented before. The software teaches programming to college students, detecting the students learning style and providing a personalized experience, we use the visual programming paradigm. This application is developed in a web environment, using as tool set: HTML, Javascript, Linux, Apache, MySQL and PHP. At the end of this work we have realized that the incremental software development methodology and the incremental development model is a good combination in the development of educational software focused on the web.

Katanga is one of the regions of the world, where we find abundant geochemical anomalies in most of these soils. These geochemical anomalies contain rich deposits mainly copper but also cobalt, zinc, cadmium and gold. The rich deposits of copper, cobalt, zinc, cadmium and gold are either in the hills or in the depths of the basement. Under these conditions these elements constituting a danger reduced to humans, plants and animals. From the time man, through its various activities (mining, metallurgical, plastic manufacturing) interrupts the strong links between these elements that begin the redistribution issues, release of these hazardous metals in the different compartments of environment: soil, water, air. They reach very high levels and become a real problem for humans. Atmospheric fallout from the rich fumes SO2 discharged through the chimney smelter plant Gecamines contributed to the accumulation of metals in the soils of Penga Penga-tray. The digging of the Quartz and brick-making contributed to the remobilization of these metals through the landscape, soil, air, and water are a serious public health problem in this part of the city Lubumbashi.

Katanga is nowadays dominated by mining activities, due to the presence of rich deposits of copper ore mainly but also cobalt, zinc, germanium and many others. These deposits left on the Katangan Copperbelt arc attracted investment capital needed to implant metal production plants (Cu, Co,…). These plants are generally hydrometallurgical expected to use large amounts of water and generated waste in the form of large quantities of liquid effluents. Sustainable Environmental Management recommends the use of modern devices to recycle wastewater from hydrometallurgical plants; unfortunately this is not the case of the STL, which discharges into the river Lubumbashi. Its rich effluents discharged minerals in the water have contributed to the change of the physicochemical conditions of the river. contents of the increase is noted in trace metals such as Cu, Co, Pb and Fe in water, soil and plants along the river Lubumbashi, through one of the Kafubu before flowing in the watershed of the Kafubu. This places the river water Lubumbashi on the list of those subject to special treatment before being used for various needs. Unfortunately, the population ignorant and uninformed on the matter is in use in the risk of contracting various diseases.

Metal contamination of soils, following local atmospheric deposition (industrial and urban) and to different inputs (compost, manure ...) or former explains in particular the presence in surface horizons, current levels ETM such as Cd, Cu, Zn and Pb. However, despite the obvious effect of accumulation, transfer of metal to the depth is also noted, usually deducted from total contents comparisons metals in different soil horizons. Among the cited metallic elements, some are essential trace elements such as zinc (Zn) and copper (Cu), but become toxic at high concentrations. Others such as lead (Pb) and cadmium (Cd) are toxic when trace. Their accumulation and transfer in the soil on the site of Penga Penga-therefore a risk to human health through contamination of the food chain but also for the environment as a whole.

In this paper, we propose a new classification algorithm called Intelligent Agent and Neuro-Fuzzy Rule based Group Support Vector Machines (IGSVM) to perform major classification of sentiments and to form groups based on the sentiments of people with respect to change in time and place. Finally, the groups are used to form discussion forums on various topics including business, e-learning, tour and sports. The main advantage of the proposed work is to identify the user interest based on the sentiments identified from tweets and to form similar interest users groups for discussion on specific topics. From the experiments conducted in this work, it is proved that the user groups formed by sentiment analysis provided more than 94% accuracy in identifying members for forming interest groups on twitter and hence is more accurate than the existing systems.

Genocide committed against the Tutsis in 1994 is a reality of the XXe century that is the specificity of Africa, since it was the first genocide that has been committed in this continent. In this manner Rwanda became unfortunately famous. The régime of Habyarimana had planned seriously and had executed genocide against the Tutsis. All the Institutions have been mobilized as well as a part of the population extremist Hutu to kill more possible Tutsi. The perpetrators had for mission to eliminate the Tutsis methodically using the lists of the names and the identification cards which mention the ethnicity. Thus, the Tutsis have been exterminated because the barriers were set up everywhere to stop the Tutsis from fleeing toward the neighboring countries. Before this genocide, the idleness of the International Community appeared a lot when some Tutsis have been killed without intervening. The following day of the beginning of slaughters in April 07 1994, the troops of RPF decided to leave their position in order to go to save the Tutsis that were again in life. The militias and the Presidential Guard killed the Tutsis while escaping the advanced of RPF toward the neighboring countries, but the big number of these perpetrators took refuge to the former Zaire, the current DRC. Finally, July 4, 1994, the RPF stopped genocide and liberated the country.

In this paper, the method was proposed a solution for the problem of an image inpainting method for missing parts or corrupted by noise of a video sequence recorded by a moving or stationary camera. The region to be inpainted may be still or moving, in the background or in the foreground, it may occlude one object or may be occluded by some other objects. This method was approached by a simple preprocessing stage and two steps of video inpainting. In the preprocessing stage, the corrupted video sequence images is extracted into multiple frames, then roughly segment each frame into foreground and background using Expectation Maximization algorithm. In segmentation, it builds three image mosaics that help to produce time consistent results and also improve the performance of the algorithm by reducing the search space. In the first video inpainting step, it reconstructs the corrupted video images of the moving objects in the foreground that are occluded. At the end of this first video inpainting, fill the gap as much as possible by copying information from the moving foreground in other frames, using a priority-based scheme. In the second step, the remaining regions are inpainted with the background. To accomplish this, first align the frames and directly copy when possible. The remaining pixels are filled in by extending spatial texture synthesis techniques to the spatiotemporal domain. This proposed framework has several advantages such as, it is simple to implement, fast and does not require statistical models of background or foreground. Works well in the presence of rich and cluttered backgrounds.

Accurate wind speed forecasting is a challenging, crucial and important task because it highly impacts on the power system and wind farm planning, scheduling and control operation. This article presents comparative performance analysis on the wind speed forecasting application based on the six artificial neural network namely, back propagation network (BPN), multi-layer perceptron network (MLPN), radial basis function network (RBFN), ELMAN network (EN), improved back propagation network (IBPN), and recursive radial basis function network (RRBFN). The real-time acquisitions utilized to forecast wind speed by means of six artificial neural networks are the 10 minutes mean wind farm data’s acquired at three acquisition location in Coimbatore region. Wind speed, wind direction, air pressure, temperature, relative humidity and dew point are taken as inputs for the six artificial neural network bases forecasting model to forecast different time scale wind speed forecasting. The effectiveness is validated by means of the five evolution error metrics such as mean absolute percentage error (MAPE), mean relative error (MRE), mean absolute error (MAE), root mean square error (RMSE), and mean square error (MSE). Simulation results revealed that even for the similar data sets, recursive radial basis function network based forecasting model outperform among the six artificial neural networks with the best forecasting accuracy and the lowest statistical errors.

The present study was undertaken with the aim to evaluate the diversity, the size and the vertical, horizontal and monthly distributions of the soil spiders in a field of cassava. Two methods were used, the" distance sampling" and the “Barber” trap. The identification of spiders was carried out using a binocular magnifying glass and identification key books of the Africa spiders. Each spiders sample was measured at the cephalothorax region with the help of graduated micrometer. The obtained results were analyzed by the mean of khi-square statistic test. 306 specimens of spiders belonging to 7 families, 10 genus and 12 species were harvested and identified. By the mean of "distance sampling" technique, 135 specimens belonging to 2 families and 7 species were captured. Lycosidae family was the most abundant (227 specimens) and the more diversified (4 species out of 7 harvested), following by the Ctenidae family (3 species out of 8 specimens). By the mean of “Barber” trap, 171 specimens belonging to 6 families were captured among which Lycosidae family was also the most abundant with 167 specimens and the more diversified (4 species out of 9 harvested) that the other (Salticidae, Gnaphosidae and Lycosidae). The ecological approach revealed that the spiders in this biotope circulate at the soil level (±0.96 cm) and that they have small sizes (2.07 mm to the level of the cephalothorax). Weeding and/or the ploughing could simplify the agro-systems and thus would involve their colonization by spiders of small sizes essential for the regulation of the population of the devastating insects of the cassava.

The aim of this work is to evaluate the nutritional value and cyanhydric acid content of eight plant species (Alchornea cordifolia, Alstonia boonei, Cola acuminata, Ficus vallis-choudae, Musanga cecropioïdes, Macaranga spinosa, Pycnanthus angolensis and Trilepisium madagascariensis) currently consumed by Okapia johnstoni in captivity at Epulu Fauna Reserve of Okapi in Democratic Republic of Congo. After two weeks of experimentation, the preference of Okapia johnstoni in consuming these plant species is in decreasing order as follow: Musanga cecropioïdes, Alchornea cordifolia, Alstonia boonei, Ficus vallis-choudae, Pycnanthus angolensis, Trilepisium madagascariensis, Macaranga spinosa and Cola acuminata. The biochemical analyses revealed that A. Boonei and C. acuminata are more rich in crude protein( 19.27% per 100 g of dry mater) and F. vallis-choudae is the richest species in the lipids (11.61%) and the poorest is A. cordifolia; M. cecropioïdes is the richest in calcium (6. 01%) against, P. angolensis which is the poorest (3.0 %); In the all plant species, magnesium is presented under the form of the trace; T. madagascariens and A. Boonei are the richest in cyanhydric acid (1, 60 mg) that P. angolensis (0, 40 mg). These results indicate that the selective choice of certain fodder to the detriment of others is a self medicative behaviour (zoopharmacognosy) in Okapi. Starting from these results, it is thus desirable that research works are carried out for the ex situ conservation of Okapi in the province of “Nord Ubangi”.

The study concerns the reproduction and structure of the populations of Sciuridae from the forest reserve of Yoko and has for objectives to identify the dominant species present in this reserve, to determine and to analyze the structure of the populations of squirrels and their reproduction phonology in order to estimate the stability of this group facing the local and global changes. The animals were harvested with the help of traditional traps from May 2014 to April 2015. From the six species captured, Funisciurus anerythrus was the most abundant, followed by the Funisciuruses bayonii, Funisciurus congicus, Paraxerus boehmi, Heliosciurus rufobrachium and Protoxerus stangeri. Their activities seem to achieve themselves in the fallows except the last two species that prefer the primary forest. The reproductive activities increase toward the middle of the rainy season (September-November) with a great proportion of the gravid females from December to February, which accompanies of a massive entry of the young during the active period from June to November. The sex-ratio is in favor of the males but the difference is not significative (p>0.05). The middle range is of two for Funisciurus anerythrus, and one for the other. The adults are abundant; the continuous presence of the young adult and juvenile reveals a continuous reproduction and the stability of the population.

Mapping land cover in complex regions like Western Cameroon Highlands is highly difficult. Most widely used algorithms are not easily implementable because of strong similarities observed in reflectance of different land cover units. This study evaluates the contribution of neural networks to the classification of LANDSAT 8 OLI images in order to achieve a better land cover map in this region. Image processing techniques (calculation of indices, principal components analysis, and color compositions) and a field survey allowed to discriminate and select trainings and validation sites of the main land cover units. Then, a network with 14 neurons in the input layer and 8 neurons in the output layer corresponding to different land cover classes was constructed. External and internal network parameters were experimentally selected for classification. The resulting map was finally validated with an overall accuracy of 90, 08% and a Kappa equal to 0.88. Eight land cover units have been identified. These are degraded forests, savannahs, bare soil and localities, water, wetlands, crops and burned areas. Finally, comparison with the maximum likelihood method has shown the superiority of neural networks with an overall accuracy difference of around 8%.

The Rouché-Fontené theorem plays a fundamental role in the study of linear equations. It gives, in fact, the general rule for solving linear systems of the type n×p (that is to say, systems of linear equations in n unknowns p, (n,p)∈N^*×N^*). This rule is based on the determination and calculation of the respective values of critical characteristics or "trimmed" and, of course, on their list, given that, as they are all zero or one of them do not be the result of a linear system which they are extracted radically changes. The demonstration to prove that the set μ(p,q,r) real matrices p×q type and rank r is a variety diving is based on the same type of reasoning based on the identification and calculation tacking matrices determinants; It can therefore rightly be regarded as a unique illustration and / or application of an aspect of Rouché-Fontené theorem. The aim of this article is precisely to show how Rouché-Fontené theorem (mainly within linear algebra) is a scope in the dives varieties theory (rather under differential geometry).

This paper aims to analyze the combined effect of couple stress and longitudinal surface roughness on the behavior of a Shliomis model based ferrofluid squeeze film in circular plates. The stochastic averaging model of Christensen and Tonder for longitudinally surface roughness has been adopted here. The generalized Reynolds’ type equation obtained by the application of Shliomis ferro-hydrodynamic model incorporating the Stoke’s micro- continuum theory has been stochastically averaged. The pressure distribution in the bearing system has been calculated taking recourse to appropriate boundary conditions. Then load carrying capacity of the bearing system is derived. The results presented in graphical forms, make it clear that the longitudinal surface roughness significantly modifies the squeeze film performance. It is clearly observed that the enhanced performance due to the combined effect of couple stress and magnetization gets further improved due to longitudinal surface roughness barring the case of negatively skewed roughness.

This study wore on the diversity and distribution of ophidians in a few protected areas in the Oriental Province (DR. Congo). The harvest data were performed at Tshuapa Lomami Lualaba Park (TL2), in the Yoko Forest Reserve (RFY) and in the Rubitele hunting area (RBTL). The collections come from the missions of Tshuapa Lomami Lualaba Park (TL2), the Yoko Forest Reserve (FRY) and Rubitele hunting area (RBTL). The Ophidians specimens were captured in actively prospecting night with a snake cane; some specimens of Ophidians were purchased from villagers. In total 91 biopsies were taken from the specimens examined belonging to 7 families 25 genera and 28 species. Using a unique method of catching sight in the three protected areas we find that the dominant species was the horned viper Bitis nasicornis (12.09%), followed by the species Boaedon olivaceus (10.99%) while Grayia smithii, Lycophidion laterale, Dendroaspis jamesoni, Causus maculatus, Natriciteres olivacea, Dasypeltis fasciata, Thrasops jacksonii, Rhamnophis aethiopissa, Thelotornis kirtlandii, Toxicodryas pulverulenta et Hapsidophrys lineatus were less represented with 1.10% for each of them. The index of Shannon - Weiner (H) show that the Yoko Forest Reserve (RFY) (H = 3,898) present a higher diversity of Ophidians than that other protected areas. The Simpson index was 0.81 for Tshuapa Lomami Lualaba park (TL2), 0.918 for Yoko Forest Reserve (RFY) and 0.907 for the Rubitele hunting area (RBTL). The equitability is 0.97; 0.917 and 0.944 respectively for the Tshuapa Lomami Lualaba Park (TL2) for the Yoko Forest Reserve (RFY) and the Rubitele hunting area (RBTL). The Species richness (RS) is 19 for the Yoko Forest Reserve (RFY), 15 for Rubitele hunting area (RBTL) and 6 for Tshuapa Lomami Lualaba Park (TL2).
