Ce mémoire est consacré `a l'analyse de sensibilité du modèle Black-Scholes Merton évaluant le prix d'une option d'achat européenne. Cette analyse évalue la part de l'influence des paramètres incertains à savoir le taux d'intérêt sans risque et la volatilité. Elle est basée sur la décomposition de la variance totale en utilisant les indices de Sobol. Nous avons utilisé la simulation Monte-Carlo pour l'estimation des indices de Sobol associés aux paramètres incertains. Nous avons aussi utilisé la technique de p-boxe combinant les deux types d'incertitudes, aléatoire et épistémique dans le même contexte. Nous avons estimé la moyenne, la variance et la fonction de densité des prix d'option d'achat européenne.

Appendicitis is the inflammation of the vermiform appendix which is the most common cause of acute abdomen in both adults and children all over the world. Appendicitis occurs most commonly between the ages of 10 and 20 years and it has a male-to-female ratio of 1.4:1. The lifetime risk is 8.6% for males and 6.7% for females in the United States , The global incidence of appendicitis is ( 100 in North America, 105 in Eastern Europe, and 150 in Western Europe) in 100.000person per year . The incidence is 160/100.000 person per year for Turkey The aim of this study is to determine the role of C-reactive protein and procalciton in as a markers to support modified Alvarado Score in differentiating Complicated Acute Appendicitis from Non-Complicated Acute Appendicitis by estimating the sensitivity and specificity of each of them, as well as which is more powerful to add to the diagnostic protocol.To achieve this aims, 100 patients suffer from acute appendicitis with ages range between (15-55) years are classified into two groups according to the severity , 60 patients with non-complicated acute appendicitis, 40 patients with complicated acute appendicitis. C-reactive protein, procalcitonin concentration were determined by enzyme linked Immunosorbent assay (ELISA)method, Also total serum bilirubin was estimated by spectrophotometric method . The results of present study reveals a significant increase in C-reactive proteincon centration (p< 0.001)in complicated acute appendicitis patients when compared to those of the non-complicated acute appendicitis patients,the sensitivity and specificity of c-reactive protein was 75%,68.7% respectively .Also significant increase in procalcitonin concentration(p < 0.001) in complicated acute appendicitis patients when compared to those of the non-complicated acute appendicitis patients,the sensitivity and specificity of procalcitonin was 75%,77.8% respectively. There was non-significant increase in concentration of total serum bilirubin in complicated acute appendicitis patients more than normal range .The results showed significant positive correlations between modified Alvarado score and C-reactive protein(r = 0.216, p < 0.05 ), significant positive correlation between modified Alvarado score and procalcitonin( r = 0.265, p < 0.05) and significant positive correlation between C-reactive protein and procalcitonin(r=0.546 , p<0.005) ,In conclusion, , C-reactive protein and Procalcitonin were more effective in patients with complicated acute appendicitis ,also positive correlations between C-reactive protein and Procalcitonin with Alvarado score strength the possibility of differentiating between complicated and non-complicated acute appendicitis and Procalcitonin was more powerful from C-reactive protein in supporting modified Alvarado score to differentiate complicated from non-complicated acute appendicitis according to their sensitivity and specificity

تعتبر الكوميديا من الأنواع المسرحية التي لقيت رواجا على المستوى العالمي عامة والجزائري خاصة، بتحليها آليات وتقنيات تبعث فينا الضحك، ولعل توظيفها واللجوء إليها راجع لما تحمله من روح الفكاهة والدعابة والتنكيت والسخرية، وذلك من أجل الترفيه وإرضاء ذائقة المتلقي، وما تطرحه لمواضيع مختلفة من عمق الواقع بأسلوب ساخر وناقد للأوضاع المعيشية لدى الفرد الجزائري وبتقنيات وأساليب كوميدية تسر مسامع المتلقي، ومسرحية "لعبة الزواج والزهر" جسدت لنا تلك الأوضاع وكشفت ما هو مستور ومخبأ بطريقة هزلية، أنست المتلقي ولو مؤقتا حالته المزرية التعسة التي يعاني منها.

Safety applications in Hybrid Vehicular Sensor Networks (HVSN) require robust transmission of messages in order to deliver safety to roads and drivers as intended. Since moving vehicles are equipped with wireless sensors that utilize and share the unreliable wireless channel for communication, the transmission of safety messages must be coordinated to minimize or completely eliminate collision of exchanged packets. The first step on the way of achieving that is through the Media Access Control (MAC) layer which is responsible for managing the access to the shared media safely and without collisions. This thesis aims at designing and implementing a HVSN MAC protocol to help exchange safety and control messages between the network elements, i.e. vehicles' on board sensors and road side sensor units. The Time Division Multiple Access (TDMA) is one of the media access techniques used for eliminating collisions. However, it imposes few challenges in implementation, namely, rescheduling and time synchronization among communicating nodes. In this proposed protocol, we provide a complete solution for such problems. Instead of dividing the time frame between just the available nodes, the protocol provides fixed schedules or time frames with enough time slots that are able to accommodate the maximum number of vehicles that may fit in one segment at a time. Such arrangement eliminates the need for re-scheduling and unnecessary processing. The synchronization problem is solved as well, with coordination from the network controller which is the road side unit. Since we are dealing with HVSN, the protocol has not only considered the network or the communication part, but also included the vehicles' behavior in the design process, through realistic mobility modeling. The mobility model and the protocol operations are employed on a small real map where vehicles interact and communicate. Moreover, a new Packet Delivery Ratio calculation method that considers the vehicles' mobility in the analysis is applied to practically evaluate the protocol performance. The devised MAC protocol is characterized by several features; first, it is a collision free MAC protocol that does not require the re-configuration of time slots division as well as it accounts for the time synchronization problem. Second, the protocol is one of the initial works that employs the IEEE 802.11 p in HVSN and utilizes its features and specifications. Third, the design is comprehensive and it is built and based on a realistic mobility model that helped in assessing the protocol performance through a unique TDMA mobility based-PDR calculation method

Drug shortage is a worldwide problem, which gained the attention of many authorities in recent years including the Egyptian government. The problem has markedly increased in Egypt during the past few years and has had a significant negative impact on patient care with subsequent costly financial implications. Despite the importance of the drug shortage problem and its consequences on the health of Egyptians and society as a whole, only a few researchers have addressed the topic in Egypt. This qualitative study aims at filling the gap and providing a better understanding of the problem in the Egyptian context. To achieve the study objective, the root causes of the problem and the actions taken by the government to mitigate the problem are explored. In-depth, semi-structured interviews are carried out with different stakeholders including from government, industry, distributors, and pharmacies. The findings of this research revealed that the drug shortage is attributed to a myriad of interlinked causes. The most critical causes of drug shortages are as follows: the drug pricing constraints, the devaluation, economic changes, overdependence on the importation of production inputs, illegal distribution practices, excessive bureaucracy and complicated procedures, manufacturing problems, poor supply chain management, and scarcity of raw materials. The findings also show that although the government has exerted many efforts to tackle drug shortages, there is still a gap to be addressed. Based on experiences of other countries and according to the Egyptian context, solutions are proposed to help in mitigating drug shortages in Egypt which include enhancing the sustainability of the production of medicines by improving companies’ profitability, improving collaboration between various stakeholders, developing a system for reporting and communication of drug shortage information, and modifying workflow within MoHP to avoid unnecessary delays.
