Towards End-to-End QoS in Ad Hoc Networks

http://citi.insa-lyon.fr/wons2006/index.htmlIn this paper, we address the problem of supporting adaptive QoS resource management in mobile ad hoc networks, by proposing an efficient model for providing proportional endto- end QoS between classes. The effectiveness of our proposed solution in meeting desired QoS differentiation at a specific node and from end-to-end are assessed by simulation using a queueing network model implemented in QNAP. The experiments results show that the proposed solution provides consistent proportional differentiation for any service class and validates our claim even under bursty traffic and fading channel conditions

Driving Factors of Urban Expansion in Peri-Urban Areas of Greater Cairo Region

Since the early 1980s, the Greater Cairo Metropolitan Region (GCMR) has witnessed a rapid urban expansion that has been mainly concentrated in the peri-urban areas (PUAs). Most of this expansion was against urban planning laws and has presented a critical challenge to the urban environment. It has also led to spatial fragmentation and loss of enormous agriculture lands. This research analyses the urban expansion in the PUAs of the GCMR, during the period (2001-2017) using GIS and remote sensing. In addition to presenting a set of driving factors of this expansion, which were extracted from the literature review and previous studies. The results of this research show that the urban expansion rate during the mentioned period reached to 461 hectares per year. Moreover, the population growth and accessibility were the most significant driving factors in the PUA of the GCR

ENVIRONMENTAL ISSUES AND CORPORATE PERFORMANCE: A CRITICAL REVIEW

the link between the environmental issues of the corporations and their economic performance and competitiveness has became one of the most popular issues to be studied in the profession. However, previous studies that have attempted to relate environmental issues to economic performance have often led to conflicting results. This paper reviewed the previous environmental literature and suggested that the inconsistency is due to the absence of clear framework that explain what actually constitutes environmental practices and how their outcomes are to be determined and evaluated. Therefore, it becomes difficult to identify general relationships between different indicators of environment and economic performance. The paper concluded that there is a lack of study investigating the relationship between disaggregated environmental practices, corporate environmental performance, and environmentally related competitiveness. Key words: environmental practices, corporate environmental performance, competitiveness, resource-based view theory

A Comparison Between Divergence Measures for Network Anomaly Detection

International audienceThis paper deals with the detection of flooding attacks which are the most common type of Denial of Service (DoS) attacks. We compare 2 divergence measures (Hellinger distance and Chi-square divergence) to analyze their detection accuracy. The performance of these statistical divergence measures are investigated in terms of true positive and false alarm ratio. A particular focus will be on how to use these measures over Sketch data structure, and which measure provides the best detection accuracy. We conduct performance analysis over publicly available real IP traces (MAWI) collected from the WIDE backbone network. Our experimental results show that Chi-square divergence outperforms Hellinger distance in network anomalies detection

Extracorporeal Shock Wave Therapy: Non‐Urological Indications and Recent Trends

Extracorporeal shockwave lithotripsy (ESWL) was introduced in 1980 as the preferred tool by the urologist for the treatment of renal stones and or upper ureteral stones. ESWL is minimally invasive procedures, exposes patients to fewer anesthesias, and has equivalent stone‐free rates comparable to open surgery and endourology interventions for the treatment of renal stones. Urolithiasis is not the only application for extracorporeal shock waves but there are also other applications for it. Extracorporeal shock wave is used for the treatment of gall bladder stones, common bile duct stone clearance, pancreatic calculi, salivary stones, erectile dysfunction, and refractory angina pectoris chronic wound healing. This chapter gives full review about ESWL as minimally invasive procedures in the following items: (i) ESWL l in treatment of gall stones; (ii) ESWL for common bile duct (CBD) stones; (iii) ESWL for pancreatic stones associated with pancreatic pseudo cysts and chronic pancreatitis; (iv) ESWL in the treatment of salivary stones; (v) ESWL in the treatment of erectile dysfunction (ED); (vi) Cardiac shock wave therapy (ESWL) in treatment of refractory angina (RA); (vii) ESWL and chronic wound healing; (viii) Recent trends in extracorporeal shockwave lithotripsy (ESWL); (ix) Post ESWL complementary therapy; and (x) The future of ESWL in the year 2038

Damage of Governmental Building Due to Geotechnical Properties (Case History)

This paper is a case study for a governmental building in a site located at Katamia zone (an extension of Great Cairo, Egypt). The site is belonging the Great Cairo Bus Station under the authority of Ministry of Transportation. It consists of two buildings and a shed for buses cleaning and lubrication. The buildings had been constructed since 15 years. However after two years of construction many cracks were noticed in the main building. Furthermore, after another few years, sever cracks had appeared in different parts of the building and the concrete water tank on the roof of same building had suffered from failure. The aim of this study is to know and examine the reasons of these cracks and damages which happened to the building, particularly the other building suffered no cracks or damages although it was built on the same soil and under the same conditions. Observation of the building movements were recorded over several years as well as soil investigation around and under the building. A structural analysis and an estimation of stresses under foundation have been calculated using a three dimensional finite element program before and after deformation. At the end of study the causes of the failure had been determined and conclusions were draw

BALANCED SCORECARD: WEAKNESSES, STRENGTHS, and ITS ABILITY as PERFORMANCE MANAGEMENT SYSTEM VERSUS OTHER PERFORMANCE MANAGEMENT SYSTEMS

Since the last decades, the performance management has become a legislative requirement for the private and public sectors. Companies are looking to find the tool that a can measure the performance effectively. One of the attractive areas subject to be measured is the social and environmental considerations. This paper provides theoretical discussion of the BSC and compares it with other different measurement systems. Moreover, it evaluates the ability of BSC to incorporate the social and environmental issues. The paper concluded that although the criticisms of BSC, it has many advantages versus other performance systems. It also strongly suggested the ability to BSC to incorporate the social and environmental issues, which can open the door for coming studies to consider such issue.   Key words: Balanced Scorecard, performance management systems, social and environmental issues

Early detection of Myocardial Infarction using WBAN

International audienceCardiovascular diseases are the leading cause of death in the world, and Myocardial Infarction (MI) is the most serious one among those diseases. Patient monitoring for an early detection of MI is important to alert medical assistance and increase the vital prognostic of patients. With the development of wearable sensor devices having wireless transmission capabilities, there is a need to develop real-time applications that are able to accurately detect MI non-invasively. In this paper, we propose a new approach for early detection of MI using wireless body area networks. The proposed approach analyzes the patient electrocardiogram (ECG) in real time and extracts from each ECG cycle the ST elevation which is a significant indicator of an upcoming MI. We use the sequential change point detection algorithm CUmulative SUM (CUSUM) to early detect any deviation in ST elevation time series, and to raise an alarm for healthcare professionals. The experimental results on the ECG of real patients show that our proposed approach can detect MI with low delay and high accuracy

Advantages of Intramedullar Fixation in Treatment of Congenital Tibial Pseudoarthrosis – A Case Report

This report describes a case of a 29-year old patient with congenital pseudoarthrosis of the distal tibia previously treated unsuccessfully by a conventional surgical method. Tibial congenital pseudoarthrosis is a rare disease characterized by segmental osseous weakness resulting in deformation of the bone and spontaneous fractures which progresses to a tibial nonunion. In our case we used intramedullary stabilization with bone grafting and six month after operation congenital pseudarthrosis of the tibia healed
