A Digital Baseband with Novel Clock Generator for UHF RFID Tag

Clock accuracy is critical to the performance of UHF (Ultra High Frequency) RFID (Radio Frequency Identification) tag, especially for the encoder in baseband. To reduce the bit error rate of the responded data from tag, a novel clock strategy is proposed in this paper, which generates a high accuracy clock for the encoder by counting the preamble of the commands from reader. Moreover, for reducing the chip area and the power consumption, a novel CRC (Cyclic Redundancy Check) generator is designed, which reuses the resource and fulfills a no-gap-link between the responded data and CRC code. The baseband of tag is implemented in a 0. 18μm CMOS process and its area is 75479μm. Simulation results show that the frequency variation of the clock is within a reasonable range. 
The Study of Strategic and Extensive form of Non- cooperative Game Theory

In this paper, we consider a wide range of widelystudied models strategic form behavioural game theory. It is standard multi agent settings to assume that agents will adopt Nash equilibrium strategies. This paper gives a brief overview of game theory. Therefore in the first section we want to outline what game theory generally is and where it is applied. In the next section, we introduce some of the most important terms of Non-cooperative game theory such as strategic form (or) normal form games, extensive form and Nash equilibrium.

Processes Controlling Tropical Tropopause Temperature and Stratospheric Water Vapor in Climate Models

A warm bias in tropical tropopause temperature is found in the Met Office Unified Model (MetUM), in common with most models from phase 5 of CMIP (CMIP5). Key dynamical, microphysical, and radiative processes influencing the tropical tropopause temperature and lower-stratospheric water vapor concentrations in climate models are investigated using the MetUM. A series of sensitivity experiments are run to separate the effects of vertical advection, ice optical and microphysical properties, convection, cirrus clouds, and atmospheric composition on simulated tropopause temperature and lower-stratospheric water vapor concentrations in the tropics. The numerical accuracy of the vertical advection, determined in the MetUM by the choice of interpolation and conservation schemes used, is found to be particularly important. Microphysical and radiative processes are found to influence stratospheric water vapor both through modifying the tropical tropopause temperature and through modifying upper-tropospheric water vapor concentrations, allowing more water vapor to be advected into the stratosphere. The representation of any of the processes discussed can act to significantly reduce biases in tropical tropopause temperature and stratospheric water vapor in a physical way, thereby improving climate simulations.
Self-Assembly through Competitive Interactions of Miscible Diblock Copolymer/Homopolymer Blends: Poly(vinylphenol-b-methyl methacrylate)/Poly(vinylpyrrolidone) Blend

We have investigated a new type A-b-B/C blend system, poly(vinylphenol-b-methyl methacrylate)/ poly(vinylpyrrolidone) (PVPh-b-PMMA)/PVP, where PVPh-b-PMMA block (A-b-B) copolymer, PVPh/PVP (A/C), and PMMA/PVP (B/C) blends are all miscible through hydrogen bond interaction or dipole-dipole interaction. Because of the significantly stronger hydrogen bond interaction between PVPh and PVP than that between PVPh and PMMA, this miscible PVPh-b-PMMA copolymer becomes immiscible up on blending with 20-60 wt % PVP (27-56 wt % PMMA in the blend system) and can self-assemble to form ordered morphologies. Results from small-angle X-ray scattering (SAXS) and TEM consistently indicate that different compositions of PVPh-b-PMMA/PVP blends induce different microphase separation structures such as hexagonal and lamellar phases. However, sharp and multiple orders of diffraction are absent from the SAXS profiles, indicating relatively limited sizes of the ordered domains. Large polydispersity in the molecular weight of PVP and small differences in the interaction parameters of the three components of PVPh, PMMA, and PVP are attributed to be the main reasons that limit the microphase separation in this blend system.
Food security in Zimbabwe: Demand for African indigenous vegetables

African Indigenous Vegetables (AIVs) are mostly leafy vegetables traditionally grown throughout Africa. Since they are domesticized versions of wild plants growing naturally throughout the continent, they are excellently adapted to the climate of the region they are growing in. Furthermore, they are rich in minerals and micronutrients and have therefore a large potential for alleviating hunger and malnutrition in Africa. Although they have a significant role in the traditional diets of many countries, economic development and change of values challenges the use of these vegetables. Little is known about consumer attitudes towards AIVs. Therefore, we analyse determinants of AIVs demand based on a consumer survey in Zimbabwe. The survey was conducted in four districts of varying prevalence of food insecurity. We analyse the relationship between household income and AIVs consumption. Second, we examine the effects of the geographical location of the household as an indicator of the socio-economic environment it is living it. Third, we explore consumers’ attitudes. Regions of lowest economic development and highest food insecurity show highest levels and variations in AIVs consumption. AIVs consumption rises the lower the income and the higher the age of the respondent is. Only for AIVs species play a significant role in consumption in Zimbabwe; these are Spider flower, Pumpkin, Cowpea and Okra. Socio-economic factors like age, income determine the quantities of the consumption of AIVs.
How You Feel About Yourself Can Affect How You Feel About Your Job: A Meta-Analysis Examining the Relationship of Core Self-Evaluations and Job Satisfaction

The construct of core self-evaluations has been recognized as one of the most significant dispositional predictors of job satisfaction. The current study meta-analyzed the relationship between core self-evaluations and job satisfaction and found a moderate, positive relationship. Characteristics of the samples (such as gender, race, age, and organizational tenure), and characteristics of the research design (such as type of core self-evaluation measurement used and author type) were examined as potential moderators of the relationship between core self-evaluations and job satisfaction in this study. The findings along with practical implications are discussed and outlined.
Auditory Supplements to Speechreading

Auditory-visual speech recognition is far more accurate and robust than speech recognition by hearing alone. Yet, in spite of the benefits and obvious importance of auditory-visual speech for everyday communication, little is known about the mechanisms involved in auditoryvisual speech integration. As a preliminary step toward the development of a generalized model of speech communication that incorporates visual speech cues, it is necessary to delineate the spectral and temporal interactions that occur when visual speech cues are used in tandem with acoustic cues. It will be shown that this interaction is both highly synergistic and non-linear. Further, it is suggested that visual speech cues may serve as a guide for auditory speech processing by informing the listener of spectral and temporal landmarks that can be used to decode the speech message.
The Application of ARGO Data to the Global Ocean Data Assimilation Operational System of NCC

In this paper, we have preliminarily studied the application of ARGO (Array for Real-time Geostrophic Oceanography) data to the Global Ocean Data Assimilation System of National Climate Center of China (NCC-GODAS), which mainly contains 4 sub-systems such as data preprocessing, real-time wind stress calculating, variational analysis and interpolating, and ocean dynamic model. For the sake of using ARGO data, the relevant adjustment and improvement have been made at the corresponding aspects in the sub- systems. Using the observation data from 1981 to 2003 including the ARGO data of 2001 to July. 2003, we have performed a series of numerical experiments on this system. Comparing with the corresponding results of NCEP, It is illustrated that using ARGO data can improve the results of NCC-GODAS in the region of the Middle Pacific, for instance SST, SSTA (SST anomalies), Nino index, sea sub-surface temperature, etc. Furthermore, it is obtained that NCC-GODAS benefits from ARGO data in the other regions such as Atlantic Ocean, Indian Ocean, and extratropical Pacific Ocean much more than in the tropical Pacific.
Epidémiologie moléculaire de la colonisation nasale par le staphylocoque doré sensible à la méthicilline (MSSA) dans une cohorte pédiatrique multi-centrique suisse

Le portage nasal du Staphylocoque dore constitue un facteur predisposant reconnu pour le developpement d’infections localisees comme systemiques. La virulence d’une souche donnee est determinee par la presence de certains elements genetiques et par l’expression de toxines. Aucune analyse moleculaire des souches de staphylocoques dores sensibles a la methicilline (MSSA) n’etait disponible dans la population pediatrique a ce jour. Notre etude a consiste en une analyse genetique sophistiquee de 572 souches de MSSA prelevees dans le nez d’enfants admis dans 8 centres pediatriques suisses et en l’etablissement des relations phylogenetiques entre elles. Nos resultats ont montre que 30% des souches de MSSA presentaient des genes exprimant une toxine ainsi qu’une grande variabilite hylogenetique. Aucune relation clonale n’a ete mise en evidence. Cette diversite suggere une pression de selection limitee dans notre pays.
Total knee replacement: a randomized study of clonidine and dexmedetomidine used for epidural postoperative analgesia

Background: Epidural anaesthesia with adjuvant is the preferred method for intra and postoperative pain relief after total knee replacement surgeries but search for ideal adjuvant for prolonging the duration of postoperative analgesia without any side effect goes on. This study was conducted to evaluate the onset, extent and duration of sensory and motor block and side effects of clonidine or dexmedetomidine when used as an adjuvant in epidural anaesthesia in total knee replacement. Methods: 60 patients of ASA status I and II, posted for total knee replacement were randomly allocated into two groups of 30 each. Group I group patients received 18 ml of 0.5% levobupivacaine and clonidine 2 mcg/kg in epidural route and Group II group patients received 18 ml of 0.5% levobupivacaine and dexmedetomidine 1.5 mcg/kg in epidural route. Intraoperative and postoperative block characteristics as well as hemodynamic parameters were observed and recorded. Results: Dexmedetomidine had an earlier onset and longer duration of sensory and motor block in comparison to clonidine. Sedation scores were statistically significant with dexmedetomidine group in comparison to clonidine group. Conclusions: Dexmedetomidine was a better than clonidine as an adjuvant to levobupivacaine in epidural anaesthesia in total knee replacement.

Influence of Capacity Management Strategies on Performance of Hotels in Mombasa County, Kenya. A Case Study of 4 Star Hotels in Mombasa County

The problem of capacity management is one of the most difficult to tackle in business management; a situation which is aggravated in the majority of services, due to uncertain demand and personalized requirements, which make it difficult to plan and assign productive capacity. While excess capacity implies extra costs, insufficient capacity implies a lower level of attention to customer needs and therefore a lack of perceived performance. The main objective of the study was to determine the influence of capacity management strategies on performance of hotels. The Specific objectives of the study was guided by the following research objectives, to determine influence of competitive positioning, influence of information communication technology, influence of customer relationship management and influence of human resource management in hotel performance. The study used primary data which was collected through use of questionnaires The target population was 63 Management staff of 4 star hotels in Mombasa County; a sample size of 54 respondents was obtained using slovin’s formula and the sample selected by probability sampling design using simple random sampling. A modified Likert scale questionnaire was developed divided into three parts. A pilot study was carried out to refine the instrument. The quality and consistency of the study was further assessed using Cronbach's alpha. Data analysis was performed on a PC computer using Statistical Package for Social Science (SPSS Version 22) for Windows. Analysis was done using frequency counts, percentages, means and standard deviation, regression, correlation and the information generated was presented in form of graphs, charts and tables. The findings of the study show that information communication, competitive positioning, customer relationship management and human resource management have an effect on performance. After each factor was tested it showed a positive significant effect. Similarly the hotel managers have a big role to play to ensure that all uncertainties inhibiting performance are mitigated to provide avenue for Industry stability. Therefore, from the findings the study concludes that human resource management plays a significant role in the performance of hotel industry in terms of ensuring they have enough competent personnel who are qualified and able to perform roles and tasks assigned to them. The study recommends policy makers in coming up with information communication geared towards improving performance of hotel industry. The study recommends that managers and other policy makers in hotel industry have the responsibility of making customer relationship policies and decisions that add value to the hotels performance.
Habitat segregation in two congeneric hawk-eagles (Spizaetus bartelsi and S. cirrhatus) in Java, Indonesia

On the island of Java, Indonesia, two congeneric hawk-eagles occur, i.e. the endemic Javan hawk-eagle Spizaetus bartelsi and the wide-ranging changeable hawk-eagle S. cirrhatus. Comparisons with similar species-pairs in South-East Asia suggest that these species may be competitors both in habitat and diet. The limited area and less-diverse resources of islands should make competition between similar species more acute and should lead to marked niche segregation, with a larger niche breath for the endemic species. Spizaetusbartelsi was recorded significantly more frequently in forest habitats from sea level to 2500 m asl and S. cirrhatus more in open habitats up to 1600 m asl. Contrary to the prediction, the endemic hawk-eagle occurred in a smaller range of habitats (four out of seven) compared with S. cirrhatus that was found in all seven habitat types. Although significant, habitat segregation was not as well marked as in some similar co-occurring Spizaetus species. The relative overlap between the two species may in part result from human influences with the dense continuous rain forest being replaced by more open forest types.
UNIVERSITÉ DU QUÉBEC EFFET DE LA VÉLOCITÉ DU COURANT SUR LA PLASTICITÉ MORPHOLOGIQUE DES PREMIERS STADES DE DÉVELOPPEMENT DE LA TRUITE ARC-EN-CIEL (Oncorhynchus mykiss) MÉMOIRE

Kevin P. Chu' and Richard Cloutier' 'Laboratoire de Biologie évolutive, Université du Québec à Rimouski, 300 allée des Ursulines, Rimouski, Québec, Canada, G5L 3AI Developmental plasticity plays a major role in evolution and provides an excellent context for unravelling the ecological implication of variation in abiotic factors to which developing fish are subjected. Water velo city has been known to induce morphological variations in salmonids, but the functional significance of these changes throughout early ontogeny are po orly documented. In this study, newly hatched specimens of rainbow trout (Oncorhynchus mykiss) were reared in four constant water-velocity treatments (0.4, 0.8, 1.6 and 3.2 cmls) for a period of 100 days. Traditional and geometric morphometrics were used complementarily to characterize morphological changes among treatments during ontogeny. Morphological plasticity induced by water velocity was detected in all size classes (15-20, 20-25, 25-30 and 30-35 mm). In the largest size class, induced morphological changes in fin shape and position were consistent with adaptations required for improved swimming ability under divergent swimming demands. However, body shape changes responded inversely to functional expectations, suggesting that body shape response to water velocity is maladaptive. This response might be caused by constraints imposed by the adaptive response of the muscular system to water velocity. Therefore, ev en under the same selective pressure, the multi-dimensionality of a fish response (i .e., changes in morphology, physiology and behaviour through ontogeny) can lead to complex interactions and compromises among its different developmental systems.
The modal performance measure for parameter optimization of power system stabilizers

This paper develops an optimization approach using the modal performance measure for the selection of power system stabilizer (PSS) parameters in multimachine power systems. The goal of the optimization problem is to damp out the sustained low frequency oscillations in the outputs of a linearized power system. Thus, the modal performance measure optimization problem is to select a set of PSS parameters so that the area under the envelop of the oscillatory output response will be minimum. This paper also considers bounded and unbounded PSS parameters and compares the effects of bounds on the end results. Furthermore, this work also shows that the performance measure is not a convex function in the PSS parameters. That is, there exist many local minima and possibly a global minimum. Single-machine infinite-bus and two-machine three-bus power systems are used to show the effectiveness of the proposed work. >

Models of AM Canum Venaticorum star outbursts

Context. Outbursting AM CVn stars exhibit outbursts similar to those observed in different types of dwarf novae. Their light-curves combine the characteristic features of SU UMa, ER UMa, Z Cam, and WZ Sge-type systems but also show a variety of properties never observed in dwarf novae. The compactness of AM CVn orbits and their unusual chemical composition make these systems valuable testbeds for outburst models. Aims. We aim for a better understanding of the role of helium in the accretion disc instability mechanism, testing the model for dwarf novae outbursts in the case of AM CVn stars, and aim to explain the outburst light-curves of these ultra-compact binaries. Methods. We calculated the properties of the hydrogen-free AM CVn stars using our previously developed numerical code adapted to the different chemical composition of these systems and supplemented with formulae accounting for mass transfer rate variations, additional sources of the disc heating, and the primary’s magnetic field. Results. We discovered how helium-dominated discs react to the thermal-viscous instability and were able to reproduce various features of the outburst cycles in the light-curves of AM CVn stars. Conclusions. The AM CVn outbursts can be explained by the suitably adapted dwarf-nova disc instability model but, as in the case of its application to hydrogen-dominated cataclysmic variables, one has to resort to additional mechanisms to account for the observed superoutbursts, dips, cycling states, and standstills. We show that the enhanced mass-transfer rate, due presumably to variable irradiation of the secondary, must not only be taken into account but is a determining factor that shapes AM CVn star outbursts. The cause of the variable secondary’s irradiation has yet to be understood; the best candidate is the precession of a tilted/warped disc.
