La technologie CMOS-MEMS pour des applications acoustiques.

Recemment, des travaux montrant la faisabilite des MEMS a base de la technologie CMOS completee par un micro-usinage en surface sans masque ont ete publies. A la difference de l'approche plus ancienne ou la liberation des composants MEMS a ete faite par une gravure du silicium, la technologie proposee consiste en la gravure des couches d'oxyde afin de liberer les couches metalliques issues de la technologie CMOS. Ce sujet de these propose donc de fabriquer des microsystemes a vocation acoustique a partir d'une technologie CMOS standard : AMS 0.35 μm. Il sera, pour cela, compose de deux parties. Dans la premiere partie, il s'agit de developper un procede technologique (determiner le type de gravure, les temps de gravure, ainsi que les dimensions extremes realisables pour les structures simples en technologie CMOS). En effet, apres avoir etudie les differentes possibilites de la technologie CMOS-MEMS proposees dans la litterature, un procede CMOSMEMS a ete mis au point. Ce procede consiste a graver une couche sacrificielle d'oxyde afin de liberer des microstructures constituees des couches metalliques issues de la technologie CMOS 0.35 μm d'AMS. Le procede est premierement teste sur des echantillons contenant des microstructures telles que des ponts et des poutres. La seconde partie du travail est consacree a la validation du procede CMOS-MEMS par un developpement de structures MEMS acoustiques representees par un microphone MEMS capacitif. Dans un premier temps, un microphone MEMS capacitif a ete realise a partir de la technologie CMOS 0.35 μm d'AMS. Apres avoir pris connaissance des differents aspects de la technologie CMOS 0.35 μm d'AMS (materiaux, dimensions, regles de dessin,.), une modelisation de microphone MEMS capacitifs est proposee grâce a la realisation d'un schema electrique equivalent base sur les analogies entre les domaines electrique, mecanique et acoustique. Chaque parametre de ce circuit est determine par l'intermediaire de relations connues et par des logiciels de simulation utilisant la methode des elements finis (ANSYS, CoventorWare). Une fois les performances des microphones estimes a partir de ce circuit equivalent, un layout, representant les differents microphones concus, a ete cree sous Cadence afin d'etre envoye au fondeur AMS. Des la reception des echantillons, le procede CMOSMEMS mise en oeuvre precedemment a ete applique afin de liberer les structures des differents dispositifs. Ensuite, une serie de caracterisations a pu etre realisee sur les premiers echantillons. Ces caracterisations visent a determiner les performances des differents dispositifs fabriques, mais aussi a estimer les proprietes mecaniques des differentes couches utilisees pour former la structure des microphones. De cette facon, le circuit equivalent pourra etre valide ou etre ameliore selon les resultats obtenus.
Dynamics and Control of Infections on Social Networks

Random mixing in host populations has been a convenient simplifying assumption in the study of epidemics, but neglects important differences in contact rates within and between population groups. For HIV/AIDS, the assumption of random mixing is inappropriate for epidemics that are concentrated in groups of people at high risk, including female sex workers (FSW) and their male clients (MCF), injection drug users (IDU) and men who have sex with men (MSM). To find out who transmits infection to whom and how that affects the spread and containment of infection remains a major empirical challenge in the epidemiology of HIV/AIDS. Here we develop a technique, based on the routine sampling of infection in linked population groups, which shows how an Asian HIV/AIDS epidemic began in FSW, was propagated mainly by IDU, and ultimately generated most cases among the female partners of MCF (FPM). Calculation of the case reproduction numbers within and between groups, and for the whole network, provides insights into control that cannot be deduced simply from observations on the prevalence of infection. Specifically, the per capita rate of HIV transmission was highest from FSW to MCF, and most HIV infections occurred in FPM, but the number of infections in the whole network is best reduced by interrupting transmission to and from IDU. This network analysis can be used to guide HIV/AIDS interventions based on needle exchange, condom distribution and antiretroviral therapy. The method requires only routine data and could be applied to infections in other populations.
Ensemble of Soft Computing Techniques for Intrusion Detection

In the present world scenario network-based computer systems have started to play progressively more vital roles. As a result they have become the main targets of our adversaries. To apply high security against intrusions and attacks, a number of software tools are being currently developed. To solve the problem of intrusion detection a number of pattern recognition and machine learning algorithms has been proposed. The paper states the problem of classifier fusion with soft labels for Intrusion Detection. Performance of Artificial Neural Networks (ANN) and Support Vector Machines (SVM) is presented here. The performance of fusing these classifiers using approaches based on DempsterShafer Theory, Average Bayes Combination and Neural Network is proposed. As shown through the experimental results combined classifiers perform better than the individual
RURAL ELDERLY CAREGIVERS: EXPLORING FOLK HOME REMEDY USE AND HEALTH PROMOTION ACTIVITIES

This exploratory study examined folk home remedy behavior and engagement in health promotion activities in rural elderly caregivers. Data was obtained with a self-report questionnaire, from a probability sample of 80 caregivers (age range = 65-84 years). Results indicated that caregivers were very involved in health promotion activities, except for exercise. Participants had high rates of folk home remedy use. Emotional health was a significant positive predictor of engagement in health promotion activities and an important factor for a healthy lifestyle in the rural, elderly caregiver. The high frequency of folk home remedy use indicates that nursing assessments should include questions about the use of folk home remedies as a measure of health promotion.
Inventaire de la biodiversité marine dans le Golfe normano-breton. Echinodermes

Ce travail est une compilation des donnees faunistiques collectees dans le golfe normano-breton et se rapportant aux echinodermes. En Manche occidentale, les laboratoires de Roscoff et de Plymouth ont etabli des inventaires tres complets de la faune et de la flore des zones cotieres situees a leur peripherie. Enrichis au fil des annees, ce sont des etats de reference de premiere importance. Aucun travail de ce type n'a encore ete entrepris dans le golfe normano-breton, carrefour biogeographique reconnu, malgre les tres nombreuses donnees recueillies sur ce site depuis les premiers travaux d'Audouin et Milne-Edwards en 1832. Ces inventaires ne sont pas passes de mode. Ce sont des supports indispensables aux travaux de bionomie marine, de repartition d'especes et d'evolution des aires de distribution. A une epoque ou les changements climatiques sont devenus une evidence et ou les transferts d'especes sont legions, ces compilations sont des bilans tres precieux. C'est aussi la possibilite de regrouper des donnees souvent peu accessibles, qu'elles soient non publiees ou qu'elles n'existent que dans des rapports ou des theses a tirage limite. [Extrait]

The Profile-based Data Processing Method Using Wireless Sensor-actuator Networks

Wireless sensor and actuator networks (WSANs) bring many gains to smart building systems. When a control system is unified by a WSAN, and particularly if the network size is wide, a distributed communication and a control method are necessary. But, multi-hop communication and packet sizes among sensors and actuators cause challenges in making such systems. This paper proposes and evaluates a new profile based data processing scheme for a smart building system with WSANs. Experimental results show that the proposed method effectively achieves the reduction of packet numbers and sizes with selfcontrolled sensors and actuators. We also discuss how to dynamically extend the service of a WSAN with only profile distributions and updates.

Evaluation of Cathodic Antigen Urine Tests for Diagnosis of Schistosoma mansoni Infection in Sudan

Background: Kato–Katz is the preferred method for the detection of Schistosoma mansoni eggs in stool. However, the sensitivity of this method is low and affected by day-to-day variation in egg excretion. Cathodic antigen urine tests have been proven to be sensitive for the diagnosis of S. mansoni infection in limited studies. Aim: To evaluate the accuracy and sensitivity of cathodic antigen urine tests for the diagnosis of S. mansoni infection. Setting and Design: This study was conducted in the Gezira Irrigation Scheme in the Gezira State, Sudan. Both S. mansoni and Schistosoma haematobium are endemic in the Gezira State. Kab-Algidad Village situated in Al Kamleen locality was selected for the study. This is a school-based, cross-sectional, comparative study. Subjects and Methods: Female school children, aged between 11 and 14 years who consented to participate, were enrolled in the study. Stool samples were examined using Kato–Katz technique and sodium dodecyl sulfate (SDS) digestion method. Urine samples were tested using the circulating cathodic antigen assays for the diagnosis of S. mansoni, and by centrifugation for S. haematobium. Statistical Analysis Used: Data were analyzed using the Scientific Package for Social Sciences version 15. Results: Cathodic antigen urine tests showed similar sensitivity to SDS and higher sensitivity compared to six Kato–Katz (reference diagnostic test). Conclusion: Cathodic antigen urine tests is a useful tool for mapping S. mansoni and may be used to evaluate the interruption of transmission.

De ontwikkeling van spraakmotorische controle II: Vroege spraakproductie in relatie tot spraakperceptie.

In het eerste artikel van dit literatuuroverzicht is bij het bespreken van spraakmotorische controle uitgebreid aandacht besteed aan het DIVA model voor spraakproductie (Guenther, 1994; 1995). Aangezien auditieve feedback in het DIVA model zeer belangrijk wordt geacht voor het vestigen van een intern model voor spraakproductie tijdens de brabbelfase, wordt hier de rol van auditieve feedback in de ontwikkeling van brabbelen bij kinderen bekeken. De beschikbaarheid van auditieve feedback blijkt zeer belangrijk voor canonisch brabbelen, een cruciale eerste ontwikkelingsfase richting volwassen spraakproductie. Na een bespreking van vroege spraakproductie, wordt overgegaan naar de invloed van spraakperceptie bij de ontwikkeling van motorische controle van spraak. Bij spraakperceptie kan fonetische informatie niet alleen auditief, maar ook visueel verkregen worden. Aan de hand van de (revised) motor theory of speech perception (Liberman & Mattingly, 1985) wordt de link gelegd tussen spraakproductie en -perceptie zoals die ook tot uiting komt in imitatie. Imitatie wordt vaak genoemd als de link tussen perceptie en productie waarbij auditieve, visuele en motorische informatie aan elkaar gekoppeld worden. Van imitatie van, door anderen geproduceerde, spraakpatronen wordt verondersteld dat het voor een kind een belangrijk leermechanisme is tijdens taalverwerving en zelfs een vereiste is om uiteindelijk tot de volwassen spraakproductie te komen.
Delivering Tailored Smoking Cessation Support via Mobile Phone Text Messaging: A Feasibility and Acceptability Evaluation of the Quittext Program

Text messaging has emerged as a potentially useful tool to help smokers quit. This paper evaluates smokers’ preferences for the Quittext program, which examines the feasibility and acceptability of delivering tailored smoking cessation advice via mobile phone text messaging. Thirty smokers completed a web-based smoking behavior questionnaire and received 6 weeks of tailored text messages. Feedback was obtained via questionnaires and semistructured interviews. Smokers reported a preference for positive support, tailoring message content, and the ability to interact with the system. Delivering quitting advice by text message was considered feasible and acceptable. This research contributes to the literature; however, further intervention evaluation is warranted, with larger controlled studies needed to fully assess program feasibility and its effect on quit rates. jabr_ 38.58 Tobacco consumption remains the single greatest cause of preventable illness and premature death in the United Kingdom (UK) with more than 114,000 people dying each year from smoking-related diseases including cancers (Peto, Lopez, Boreham, Thun, & Heath, 1994). In 2008, the prevalence of smoking in the U.K. adult population was approximately 21% (Robinson & Bugler, 2010). However, two thirds (67%) of current smokers report wanting to give up, with three quarters saying that they have tried to give up sometime in the past (The Health and Social Care Information Centre, 2010). While rates of smoking today are declining, it has been estimated that smoking in the UK is costing the National Health Service around £5.2 billion each year (Allender, Balakrishnan, Scarborough, Webster, & Rayner, 2009).
Simulation analysis of DC power-supply system stability

The authors' new circuit model for simulating the stability of a DC power supply system provides a good trade-off between accuracy and calculation time. The simulated oscillation amplitude and frequency are within 10% of those obtained from an experimental system. The calculation took only a few minutes to complete. Moreover, the threshold voltage, which corresponds to the input voltage when capacitors are added to prevent oscillation, is also within 10% of the measured value. The effect of added capacitance and damping resistance on the stability of the DC power-supply system, the size of the stability region, and the stability margin of the system are also estimated with the model.
A Gradient-Based Approach for Discrete-Time Average Consensus with Self-Triggered Control

In this paper, we present a self-triggered control scheme for discrete-time average consensus problems. In the conventional time-triggered control, each agent has to periodically exchange information with its neighbor agents and update their inputs. On the other hand, in the self-triggered control, they can avoid such inefficient usage of computational resources by exchanging information and updating their inputs only when necessary. We show that the proposed discretetime consensus protocol with synchronized self-triggered control achieves an average consensus based on the analysis of gradient-like iterative algorithms.
Verification of Initialization Sequences for Sequential Circuits

This article suggests an approach for verification of initializing sequences. Such sequences were discovered using circuit emulating software prototypes. Software prototypes operate using bivalent logics (0 and 1), while hardware testing employs ternary logic (0, 1 and X). Experimental results show, that validation using ternary logic is too strict, labeling good initializing sequences as bad ones. Experimental results are based on ISCAS'89 benchmark.

Influences of Physalis peruviana L. and Lupinus albus L. fruits extracts on the levels of some biochemical parameters in brain and muscle tissues of type II diabetic rats

New functional foods are increasingly sought to improve the treatment of diseases related to glucose and lipid metabolism. The present study was designed to investigate the possible antidiabetic and antioxidant effects of goldenberry and lupin on brain and muscle tissues of streptozotocin-induced type II diabetic rats. Type II diabetes was produced in albino rats by the streptozotocin injection. Wistar albino rats were divided into four groups, each one containing 10 rats: non-diabetic control group, STZ- type II Diabetes group, STZ- type II Diabetes+goldenberry group, and STZ- type II Diabetes+lupin group. After one week from the injection, goldenberry and lupin were injected to rats for 2 months. Malondialdehyde, glutathione, cholesterol, and fatty acid levels, which are signs of lipid peroxidation, were measured in brain and muscle tissues. In type II diabetes, malondialdehyde increased compared to the control group. Glutathione decreased in the both tissues and all of the streptozotocin-induced diabetic groups. In type II diabetes, brain cholesterol levels decreased. Treatment with similar doses of goldenberry and lupin significantly reduced oxidative stress, augments antioxidant system and altered fatty acid metabolism in these tissues, thereby maintaining favourable fatty acid distribution affected by diabetic complications. These results validate the use of goldenberry and lupin fruits as a treatment against diabetes mellitus and its complications and suggest it is suitable to continue studies for its safe therapeutic use.
A Review on Edema

Edema is a swelling which is caused due to accumulation of fluid due to release of fluid from small blood vessels (capillaries) or interstitial spaces to nearby tissues. It may affect a small area or even entire body. The affected body part is considered to be edematous. Edema is most commonly seen in the legs, feet, ankles and it can even affect other body parts. Edema is a side effect in many medications. The article presents information on the types, symptoms, causes, diagnosis and treatment of edema.
A Low Power High Energy Efficiency Flexible Programmable Gain Amplifier for RF Transceiver Circuits

A low power high energy efficiency flexible programmable gain amplifier (PGA) was presented, of which the bandwidth/power can be configured over a wide range. The optimal configuration of power consumption which gives high energy efficiency is achieved through a novel constant bandwidth technique. The proposed PGA was implemented in 130nm CMOS process, the post simulation results show that the power consumption is from 0.13mA to 1.66mA from 1.2V power supply, the bandwidth can be configured from 2.3MHz to 15.8MHz, and the gain range can be programmed from -6dB to 20dB with a gain step of 2dB. The designed PGA can be widely used in multi-frequency and multi-mode RF transceiver circuits.
Free movimg pattern's Online Spanning Tree Coverage Algorithm

The coverage path planning algorithm can be defined as making integration the robot's footprint identical to that of the target region [Choset]. The spanning tree coverage which is one of the coverage path planning algorithm is proved to be optimal in the sense that there is no repetitive coverage [Gabriely]. But the online version of spanning tee coverage shows spiral moving pattern which can cause severe localization problems. So we propose a free moving pattern's online spanning tree coverage algorithm which can freely make any moving pattern to lessen the localization or moving pattern's problem and meet the user request
A Novel Algorithm for Edge Detection of Noisy Medical Images

Medical image edge detection is an important work for object recognition of the human organs, and it is an essential pre-processing step in medical image segmentation and 3D reconstruction. Although many edge-detection evaluation methods have been developed in the past years, however this is still a challenging and unsolved problem. Conventionally, edge is detected according to some early brought forward algorithms like Canny, LOG, Sobel, Prewitt, Roberts algorithms but in theory they belong to the high pass filtering, which are not fit for noise medical image edge detection because noise and edge belong to the scope of high frequency. In real world applications, medical images contain object boundaries and object shadows and noise. Therefore, they may be difficult to distinguish the exact edge from noise or trivial geometric features. After studying all traditional methods of edge detection, it has been analyzed that for these situations, a new algorithm is needed which is optimal. In this paper, we propose a new algorithm for edge detection of noisy medical images based on both Tsallis and Shannon entropy together. The performance of our method is compared against other methods by using blood cells image corrupted with various levels of "salt and pepper". It is observed that the proposed algorithm displayed superior noise resilience and decrease the computation time.
Measurement in elderly chronic care populations

This is one of the first volumes to address specific assessment measures that will accurately describe and predict the health status of individuals from chronic care populations. Throughout this volume, prestigious researchers provide reviews of measures that can be used among these individuals, whose assessment is often complicated because of factors such as frailty, perceptual and communication problems, and advanced cognitive impairment. This volume is a valuable resource and aid for clinicians and researchers in the selection of better assessment measures for the elderly in chronic care settings.
