Towards Creating a Model of IoT to be used in Library Activities for Saudi Arabia\u27s Taibah University

The library must create a replacement organisation system in instruction to swap the existing system with the new one. There are several details why library operates need to adopt a new scheme, including the following: I have lost a lot of info on library books. The lack of familiarity with the literature Difficulty deciphering the fine print of library operations because of a sluggish system Difficulty in maintaining current information. Apart from orientation, the user interfaces are pleasant, and retraining was required. The researcher suggests that this approach be used on an ongoing basis to ensure the continued provision of library services. Other management responsibilities include serials and magazines, as well as reservations book, e-mail notice, and automated reminder, as well as the use of bar codes, scanners, and labels, as well as the custom of regularity identification tags to reduce book theft. Additionally, it is suggested that the library system engage in online surfing to enable users to access books and courses through the internet. The proposed research project would contribute to the development of a model IoT application for library operations at TIBA University in Saudi Arabia. The new system will manage and regulate all library information, resolving the aforementioned issues while also providing numerous advantages to staff and students

Results for the response function determination of the Compact Neutron Spectrometer

The Compact Neutron Spectrometer (CNS) is a Joint European Torus (JET) Enhancement Project, designed for fusion diagnostics in different plasma scenarios. The CNS is based on a liquid scintillator (BC501A) which allows good discrimination between neutron and gamma radiation. Neutron spectrometry with a BC501A spectrometer requires the use of a reliable, fully characterized detector. The determination of the response matrix was carried out at the Ion Accelerator Facility (PIAF) of the Physikalisch-Technische Bundesanstalt (PTB). This facility provides several monoenergetic beams (2.5, 8, 10, 12 and 14 MeV) and a 'white field'(Emax ~17 MeV), which allows for a full characterization of the spectrometer in the region of interest (from ~1.5 MeV to ~17 MeV. The energy of the incoming neutrons was determined by the time of flight method (TOF), with time resolution in the order of 1 ns. To check the response matrix, the measured pulse height spectra were unfolded with the code MAXED and the resulting energy distributions were compared with those obtained from TOF. The CNS project required modification of the PTB BC501A spectrometer design, to replace an analog data acquisition system (NIM modules) with a digital system developed by the 'Ente per le Nuove tecnologie, l'Energia e l'Ambiente' (ENEA). Results for the new digital system were evaluated using new software developed specifically for this project.Comment: Proceedings of FNDA 201

Brokerage

Dominant intermediaries are a defining feature of the modern economy. This paper studies the mechanisms that give rise to trading networks with a dominant intermediary. Trades between actors require a direct link or a path that involves intermediaries. Links are costly. Efficiency therefore pushes towards connected networks with few links: this set includes the hub-spoke network, the cycle network and their variants. The hub-spoke network exhibits extreme inequality, while the cycle network yields equal payoffs for all traders. We conduct a large scale experiment on link formation among traders; the game takes place in continuous time and allows for asynchronous choices. The main finding is that the pricing protocol - the rule dividing the surplus between traders and intermediaries - determines which of these two networks arises

Large Scale Experiments on Networks: A New Platform with Applications

This paper presents a new platform for large scale networks experiments in continuous time. The versatility of the platform is illustrated through three experiments: a game of linking, a linking game with public goods, and a linking game with trading an

Etude comparative de protocoles de vaccination contre la maladie de Newcastle dans les élevages modernes de poules pondeuses au Sénégal

Plusieurs protocoles de vaccination contre la maladie de Newcastle sont utilisés au Sénégal sur les poulettes futures pondeuses en élevage moderne. Cependant, chaque année, cette virose se manifeste par des mortalités ou des chutes de ponte qui grèvent le budget des exploitants de la filière. Afin de déterminer l'efficacité de la prophylaxie médicale mise en oeuvre, il a donc été procédé à une comparaison des différents schémas de vaccination dans les conditions réelles de production. Il s'avère que les programmes vaccinaux comportant essentiellement des vaccins vivants fournissent une moins bonne protection que ceux qui ont recours aux vaccins inactivés huileux injectables, sans doute à cause du manque de technicité dans l'administration des vaccins vivants. Une primo vaccination associant un vaccin vivant administré individuellement par trempage du bec et une injection de vaccin inactivé huileux procure une bonne protection pendant les dix premières semaines de la vie. Une nouvelle injection à cette période permet d'assurer une couverture pendant toute la durée de l'élevage de la poulette et améliore l'effet de la vaccination par injection à l'entrée en ponte. Dès lors, aucun rappel n'est nécessaire jusqu'à la réforme des pondeuses. (Résumé d'auteur

Connectors and Influencers

We conduct an experiment to understand the principles that govern network formation. The design of the experiment builds on a model of linking and efforts taken from Galeotti and Goyal [2010]. In order to reduce cognitive complexity facing human subjects and facilitate learning, we develop a new experimental platform that integrates a network visualization tool using an algorithm of Barnes and Hut [1986] with an interactive tool of asynchronous choices in continuous time. Our experiment provides strong support for macroscopic predictions of the theory: there is specialization in linking and efforts across all treatments. Moreover, and in line with the theory, the specialization is more pronounced in larger groups. Thus subjects abide by the law of the few. Information on payoffs provided to subjects affects their behavior and yields differential welfare consequences. In the treatment where subjects see only their own payoffs, in large groups, the most connected individuals compete fiercely-they exert large efforts and have small earnings. By contrast, when a subject sees everyone's payoffs, in large groups, the most connected individuals engage in less intense competition-they exert little effort and have large earnings. The effects of information are much more muted in small groups

Age at menarche in Canada: results from the National Longitudinal Survey of Children & Youth

<p>Abstract</p> <p>Background</p> <p>Given the downward trend in age at menarche and its implications for the reproductive health and wellbeing of women, little is known about menarcheal age in Canada. Most Canadian studies are only representative of specific populations. The present study, therefore, aims to assess the distribution of age at menarche for Canadian girls and explore its variation across socio-economic and demographic factors.</p> <p>Methods</p> <p>The analysis of the study was based on all female respondents aged 14 to 17 years during Cycle 4 (2000/2001) of the National Longitudinal Survey of Children & Youth (NLSCY). The main outcome was age at menarche assessed as the month and year of the occurrence of the first menstrual cycle. Kaplan Meier was used to estimate the mean and median of age at menarche. Chi-square test was used to assess the differences in early, average and later maturers across the different levels of socio-economic and demographic variables. Bootstrapping was performed to account for the complex sampling design.</p> <p>Results</p> <p>The total number of girls analyzed in this study was 1,403 weighted to represent 601,911 Canadian girls. The estimated mean and median of age at menarche was 12.72 years (standard deviation = 1.05) and 12.67 years, respectively. The proportions of early (< 11.53 years), average (≥11.53 years and ≤13.91 years) and late maturers (> 13.91 years) were 14.6% (95% confidence interval (CI): 11.92-17.35), 68.0% (95% CI: 63.82-72.17) and 17.4% (95% CI: 14.10-20.63), respectively. Variations across the menarcheal groups were statistically significant for the province of residence, household income and family type.</p> <p>Conclusion</p> <p>The findings of the study pave the way for future Canadian research. More studies are warranted to understand menarcheal age in terms of its variation across the provinces, the secular trend over time and its potential predictors.</p

The prominent role of the heaviest fragment in multifragmentation and phase transition for hot nuclei

The role played by the heaviest fragment in partitions of multifragmenting hot nuclei is emphasized. Its size/charge distribution (mean value, fluctuations and shape) gives information on properties of fragmenting nuclei and on the associated phase transition.Comment: 11 pages, Proceedings of IWND09, August 23-25, Shanghai (China

First neutron spectroscopy measurements in the ASDEX Upgrade tokamak

Abstract: A compact neutron spectrometer based on the liquid scintil-lator BC501A has been installed on the ASDEX Upgrade tokamak. The aim is to measure neutron energy distribution functions as footprints of fast ions distribution functions, generated mainly via Neutral Beam Injection (NBI) in present day tokamaks. A flexible and fast software has been developed to perform digital pulse shape separation and to evaluate pulse height spectra. First measurements of count rates and pulse height spectra show a good sig-nal to noise ratio for integration times comparable to the NBI slowing down time and to the energy confinement time. Due to the perpendicular line of sight, D-d fusion with perpendicular NBI is detected more efficiently and the line broadening of the 2.45 MeV neutrons is higher. Ion Cyclotron Reso-nance Heating (ICRH) combined to NBI exhibits a synergy effect, with count rates higher than the sum of the counts due to NBI and ICRH separately. Although the collimator is designed to screen gammas as much as possible, some qualitative gamma analysis is also possible, providing information in case of runaway electrons during disruptions. The experimental campaign for the characterisation of the system (detector + acquisition system) is complete and the determination of the response function is in progress.
