LMI Approach to Robust Iterative Learning Control for Linear Systems with Disturbances
Olfa Kouki, Chaouki Mnasri, Nizar Toujeni and Moncef Gasmi
This article focuses on the control of linear uncertain systems, subjected by disturbances, to cancel the effects of this latter and to follow the reference model. To achieve this goal, we proposed an approach based on robust control and iterative learning control at the same time. The H infinity norm is adopted to prove the monotonic convergence of the system based on the resolution techniques of linear matrix inequalities LMI. The effectiveness of our approach is demonstrated by the simulation results on a mechanical linear system.

The objective of this study is to show the environmental pollution by sewage dye assessing, on the one hand, their physical and chemical parameters and secondly those water wells surrounding the dye.
The wastewater analysis shows that they are very alkaline (pH> 10) and highly loaded with organic material in high concentrations of COD (212.25 mg / L to Adjamé and 877.4 mg / L to Abobo) and BOD5 (139.2 mg / L to Adjamé and 599.12 mg / L to Abobo). It also appears that these waters are loaded with minerals (CND Avg = 3196.6 microseconds / cm to Adjamé and 2876.6 microseconds / cm to Abobo) and particulate matter (SPM mean = 114.13 mg / L and to Adjamé 684.4 mg / L to Abobo). The values of these parameters far exceed WHO guidelines in raw sewage.
As for water wells show contamination of the environment, their analysis shows that they are less alkaline (7 < pH < 8) and loaded with organic and inorganic matter concentrations exceeding overall for conductivity, turbidity, COD, sulphate, ammonium and chromium, the WHO standards. These water wells have physicochemical properties that they are not recommended for human consumption.

Une étude a été conduite de novembre 2012 à mai 2013 dans le but de déterminer la qualité physico-chimique et la dynamique d’abondance des formes de contamination des helminthes intestinaux dans les eaux à Yaoundé. Des échantillonnages mensuels ont été effectués sur trois points du cours d’eau Ntem et sur trois effluents: un effluent domestique du quartier Ngousso, l’effluent de l’hôpital gynéco-obstétrique et pédiatrique de Yaoundé et l’effluent de l’hôpital général de Yaoundé. Les analyses physico-chimiques montrent que le bassin versant du Ntem est très anthropisé et ses eaux très minéralisées (688,26±449,23 µS/cm), riches en matières organiques biodégradables (55,55±19,58 mg/L d’O2). L’observation des éléments parasitaires s’est faite au microscope inversé de marque Olympus CK2 suivant les techniques formol-éther et Kato-Katz. Les résultats révélent la présence des agents pathogènes des genres Ascaris
(15 ± 2 œufs/L), Trychostrongylus
(21 ± 22 œufs/L),Strongyloides
(14 ± 16 larves/L), Taenia
(22 ± 16 œufs/L), et des espèces Hymenolepis nana
(20 ± 18 œufs/L) et Hymenolepis diminuta
(7 ± 5 œufs/L).Les analyses statistiques montrent des corrélations significatives (P<0,05) entre la densité de ces éléments parasitaires et les paramètres physico-chimiques comme la température, l’oxygène dissous, le CO2 dissous, les MES, la turbidité et les orthophosphates.

Cooperative Medium Access Control Protocol for Mobile Ad-hoc Networks
Tazeem Ahmad Khan and M. T Beg
In this paper, Aim of the study is to enhance the performance of the wireless network in noisy atmospheric conditions (fading channel environment) with the help of intermediate nodes. When source to destination transmission fails due to fading channel environment or random change in range of transmission, intermediate nodes help to transmit a packet. Wireless network are of two different types: centralized control and ad-hoc network. In this work, it is proposed to implement cooperative scheme on MAC layer level to enhance the performance of the mobile ad-hoc network. Cooperative scheme is to help the packet transmission with five handshakes instead of four. Performance analysis depends upon packet delivery ratio, received packets, loss packets, data rate and end to end delay. Our simulation supports 802.11 MAC layer mobile networks with cooperative scheme in CSMA/CA protocol. We analyze the performance using ns-2, a discrete time simulator.
Keywords: 802.11, CSMA/CA, NS-2, MAC layer, MANET.

Alia Nazir, Muhammad Afzal Khan, Fazal-E-Aleem, Shazia Bano and Saeed Ahmad Buzdar
A quality control phantom may help in assuring the accuracy of a measurement sequence and in detecting sources of error in the dose maps. In this study we have developed a dosimeter gel system by using Xylenol orange dye with Fricke-Benzoic solution. The gel system was irradiated with different radiation doses while using 6MV photon beam from Varian Clinic Linear Accelerator. The gel system was scanned by Magnetic Resonance Imaging using Spin Echo and Inversion recovery sequences. Conventional Spin Echo (CSE) and Fluid Attenuated inversion recovery (FLAIR) sequences were used to calculate relaxation times (R1 & R2). A dose profile was also extracted by using both sequences. FBX gel provides a linearity of sensitivity with absorbed dose up to a range of 20Gy. The extraction of dose profiles with maximum percentage difference of 4% has been found which establishes reliability of this gel system and technique for obtaining the information about spatial absorbed dose distribution.

Contract Farming Thai-Laos Cabbage: Problems and Guidelines for Marketing Development
This study is three fold: (1) to learn the reasons to participate in the Thai-Lao contract farming project, (2) to study the appropriate form of contract cabbage farming: cabbage and (3) to study the development of the marketing of cabbage from source to terminal market or Thai entrepreneurs. The sample was randomized by purposive sampling of the agriculturists participating in the contract farming project who were able to provide true data. 10 months were spent on the study. Questionnaires and semi-structured interviews were employed as research tools. Percentage and frequency were used to analyze the information. The research revealed that (1) Lao agriculturists participation in the contract farming project was because cabbage has become a popular alternative vegetable in the area (50.00%), secondly there is a guaranteed market in which to distribute the product (44.64%) and lastly there is a guaranteed price (30.36%), (2) the appropriate form for contract farming between Thai-Laos was when the entrepreneurs of both country drew the legal agreement because the neighboring counterparts were unable to do the contract directly with the Thais because of limiting laws in the Laos PDR. Therefore, the existing form of legal agreement is contract marketing and (3) a good relationship between cross-border entrepreneurs comes from the development of the marketing of cabbage which is based on a relationship as dependent stakeholders not just as traders and a buyers. Additionally, the government agents need to solve the problem of bribery that occurred with theThai entrepreneurs.

Financial Data Mining by Multiple Kern`el Machines and Dimensionality Reductions
Shian-Chang Huang, Chi-Yun Chiang, Ming-Hsiang Huang and Chih-Wei Lee
Financial statement analysis provides the basis for understanding and evaluating the results of business operations and delivering how well a business is doing. This paper proposes a novel approach to detect financial bankruptcies by analysing high-dimensional financial statement data. In this study, a composite kernel machine (CKM) on a kernel local fisher discriminant space (KLFDS) was constructed for analysing financial data, which solved three problems in high-dimensional data mining: the curse of dimensionality, data complexity and nonlinearity. In risk assessments, the detector, CKM, exploits multiple data sources with strong capability to identify the relevant ones and their apposite kernel (or data) representation. KLFDS is an optimal projection of original data to a low-dimensional space which maximizes the margin between data points from different classes at each local area of a data manifold. This new system robustly overcomes the weaknesses of CKMs, and outperforms many traditional classification systems in bankruptcy detections.

The Chromatic Number and Graph Folding
E. EL-Kholy and N. El-Sharkawey
In this paper we examined the relation between folding a graph and its chromatic number. We proved that any simple connected graph with number of edges greater than or equal to two and chromatic number two can be folded to an edge and hence do the cycle graph Cn, n is even. But Cn, n is odd can be folded to C3. We also proved that the wheel graph Wn, n even can not be folded while Wn, n is odd can be folded to C3. Finally we proved that if the clique number equal to the chromatic number equal to two, the graph can be folded to an edge, but if 2 < clique number = chromatic number = k < n, n is the number of V(G) then the graph can be colded to a clique of order k.

An Evaluation of Economic Values of the Alcoholic Drinking Quitting Projects
The Alcohol Quitting Projects are accepted as activities that might create noticeable tangible and or intangible benefits. One of a project measurable indicators of change is Social Return On Investment (SROI). The economic valuation by using SROI as a measure of change created by the project that affect its stakeholders, in the form of monetary value is one of the valid methods to assist a decision maker in conducting the most beneficial resource distribution between multiple projects: by prioritizing the project that create the most value among others.
