The paper presents a case study that investigated the role of modern technology applications in rainfall flooding disasters prevention. The results reported demonstrated that modern technology facilities can be used to derive preventive measures for rainfall flooding disasters. Free of charge application programs and space technology data can be downloaded and used to achieve this purpose. The derived parameters of the hydrological and topographical models can be integrated with the drainage network of the area to ensure the draining of the water and prevent it from backing up and accumulating in the low land areas. An appreciated relief effort had been made by the local governments and non-government organizations related to rainfall flooding disasters across the world. However, it is high time to devote some of this effort to the application of modern technology facilities to tackle these rainfall disasters existing causes and provide future preventive measures.

In this paper, a methodology for sleep apnea detection based on ECG signal analysis using Hilbert transform is proposed. The proposed work comprises a sequential procedure of preprocessing, QRS complex detection using Hilbert Transform, feature extraction from the detected QRS complex and the feature reduction using principal component analysis (PCA). Finally, the classification of the ECG signal recordings has been done using two different artificial neural networks (ANN), one trained with Levenberg-Marquardt (LM) algorithm and the other trained with Scaled Conjugate Gradient (SCG) method guided by K means clustering. The result of classification of the input ECG record is as either belonging to Apnea or Normal category. The performance measures of classification using the two classification algorithms are compared. The experimental results indicate that the SCG algorithm guided by K means clustering (ANN-SCG) has outperformed the LM algorithm (ANN-LM) by attaining accuracy, sensitivity and specificity values as 99.2%, 96% and 97% respectively, besides the saving achieved in terms of reduced number of principal components. Profiling time and mean square error of the ANN classifier trained with SCG algorithm is significantly reduced by 58% and 83%, respectively, as compared to LM algorithm.

From the project of the date and time reading in the Radar images, the OCR templates technique was applied because some Radar images do not have date and time information in their properties. The method had the problems that the Radar images could not be retrieved when the month names are changed and then the new month name templates had to be created. Therefore, this work has applied Tesseract OCR library to help read the date and time images and used Fast Normalized Cross-Correlation theory to enhance the performance of the template matching and to retrieve more Radar images. The accuracy of results in this program using Fast Normalized Cross-Correlation with OCR templates was 86 percent.

As the lifetime of human being gets longer, the problems of chronic diseases grow more. In order to make sure the health statuses of patients are not getting worse, they must be health-monitored continuously in a long term. In this paper, a mobile health-monitoring system is built for patients in place of traditional health-caring manners, which not only gives patients more free spaces, but also can save medical resources, diagnose and predict diseases earlier. In the procedures of health-caring in-house and emergency treatment, a series of vital sensors are combined by integrating sensor network and wireless/mobile network technology to continuously transmit physiological signals of patients to a medical center in a real time, and then doctors can monitor the health statuses of patients exactly, thereby proceeding with diagnosing, recovering, and treatments.

La certification des coopératives a été envisagée à partir de la campagne 2004/2005 pour faire face à la menace des pays exportateurs de ne plus payer le cacao ivoirien du fait du travail d’enfants dans les exploitations. Cette politique vise non seulement à garantir la vente du cacao, mais aussi à assurer aux producteurs de meilleurs prix. Mais, la certification des premières coopératives cacaoyères soulève déjà de nouveaux problèmes de développement rural. La certification est source de différenciation sociale et de tensions sociales entre les membres des coopératives certifiées. L’objectif de l’étude est de comprendre le lien entre la mise en œuvre de cette politique de certification des coopératives et les problèmes survenus à la suite. Notre enquête menée auprès des agents des ONG de certification (UTZ Certified) et d’organismes de certification agréés (Bureau Véritas), des responsables des coopératives certifiées (Directeurs Généraux, Administrateur de groupe, Paysans Relais) et des producteurs-membres de quatre coopératives révèle que la certification du cacao n’a pu prendre en compte l’entièreté des producteurs de sorte que tous n’ont pu bénéficier de la prime de certification. Dans la coopérative COOPADIS d’Issia par exemple, seulement 52,35% sont certifiés sur un total de 3293 coopérateurs. La certification a ainsi entrainé la catégorisation des paysans à l’origine de la stratification économique et de la fragilisation de la cohésion sociale dans les communautés rurales.

The work presented in this paper describe the design and simulation of a MEMS (Micro Electro Mechanical System) system based piezoelectric sensor for detecting arterial pulse in biomedical application. The study is done through the analysis of square and circular diaphragm made out of piezoelectric and MEMS material. In this work, piezoelectric material is used which work on the principle of piezoelectric effect. In piezoelectric effect, diaphragm reorients under stress, form an internal polarization which result in crystal charge on the crystal face that is proportional to applied pressure. When pressure is applied on diaphragm deformation occurs which converts physical energy into output electrical voltage. For selecting the appropriate geometry and material for sensor design different parameter were checked such as deformation, output voltage, Stress and linearity. FEM analysis is done for circular and square diaphragm on COMSOL Multi-Physics. Comparison of square and circular diaphragm is done on the basis of deformation and Electrical potential. Piezoelectric sensor is designed and simulated with lithium-Niobate and poly-si. Sensitivity obtained for the designed sensor is about 4mV/Kpa.
