Conception et caractérisation de circuits intégrés résistants aux radiations pour les détecteurs de particules du LHC en technologies CMOS submicroniques profondes

L'electronique associee aux detecteurs de particules du grand collisionneur de hadrons (lhc, actuellement en construction au cern), fonctionnera dans un environnement tres radioactif. Cette these propose une methodologie permettant de concevoir des circuits integres (cis) resistants aux radiations en utilisant une technologie cmos submicronique commerciale. Cette approche exploite la resistance intrinseque aux radiations des oxydes de grilles ultra minces, et utilise les transistors a geometrie ferme (enclosed layout transistors, elts) et les anneaux de garde pour empecher la creation, induite par l'irradiation, de courants de fuite. Pour verifier le niveau de tolerance aux radiations qui peut etre atteint avec l'approche proposee, plusieurs structures de test ont ete dessinees et testees avec differentes sources de radiations. Ces tests nous ont permis d'etudier les phenomenes physiques responsables des degats induits par les radiations, et leur possibles solutions. Ensuite, nous avons explore les caracteristiques particulieres des transistors a geometrie fermee et leur influence sur la conception de circuits integres complexes. La modelisation du rapport w/l, les asymetries (par exemple, dans la conductance de sortie) et la performance de l'appariement des elts n'avaient jamais ete etudiees auparavant. Nous avons aussi caracterise, avant et apres irradiation, la performance en bruit de la technologie cmos 0. 25 m qui est utilisee pour la conception de plusieurs cis pour les detecteurs du lhc. Finalement, deux cis concus avec la methodologie proposee sont presentes. Le premier est une memoire analogique, utilise pour verifier la tenue aux radiations de circuits a capacites commutees aux quels on a applique les techniques presentees. Le deuxieme est un ci qui serait utilise pour la lecture des signaux d'un des detecteurs du lhc. Les deux circuits ont ete irradies et ont supporte des doses tres elevees sans pratiquement montrer aucune degradation des performances.
Analysis of a Centrifugal Fan for Performance Enhancement using Converging Boundary Layer Suction Slots S World

Generally flow behavior in centrifugal fan is observed to be in a state of instability with flow separation zones on suction surface as well as near the front shroud. Overall performance of the diffusion process in a centrifugal fan could be enhanced by judiciously introducing the boundary layer suction slots. With easy accessibility of CFD as an analytical tool, an extensive numerical whole field analysis of the effect of boundary layer suction slots in discrete regions of suspected separation points is possible. This paper attempts to explore the effect of boundary layer suction slots corresponding to various geometrical locations on the impeller with converging configurations for the slots. The analysis shows that the converging suction slots located on the impeller blade about 25% from the trailing edge, significantly improves the static pressure recovery across the fan. Also it is found that Slots provided at a radial distance of about 12% from the leading and trailing edges marginally improve the static pressure recovery across the fan. Keywords—Boundary layer suction converging slot, Flow separation, Sliding mesh, Unsteady analysis, Recirculation zone, Jets and wakes.
The Value of Relationship and Communication Management in Fundraising: Comparing Donors' and Practitioners' Views of Stewardship

The organisation-public relationship paradigm has frequently referenced Kelly’s (2001) stewardship strategies as possible methods for strengthening relationships with stakeholders; however, there have been no attempts to measure stewardship. A mailed survey of individual donors (n = 1,706) and fundraising team members (n = 124) at three non-profit hospitals asked participants to evaluate their views toward the four stewardship strategies as well as estimate how the other side would evaluate them. By using the coorientation methodology, this study found that although both sides valued the four stewardship strategies, their attitudes differed in magnitude. These findings provide growing support for future examination of stewardship in other public relations settings, and specifically they add to the growing literature on the importance of donor cultivation.

Laypersons' expectations of recovery and beliefs about whiplash injury: A cross‐cultural comparison between Australians and Singaporeans

Beliefs and expectations are thought to influence outcome following whiplash injury. Studies have proposed a link between rates of chronic whiplash and laypersons' expectations about outcome following a motor vehicle accident. The prevalence of chronic whiplash is relatively high in Australia and apparently low in Singapore. This study's objectives were to compare laypersons' beliefs and expectations of recovery of whiplash injury in Brisbane and Singapore and to assess the effect of demographic factors on whiplash beliefs.
The effect of internal controls on financial reporting quality in Iranian family firms

PurposeThe purpose of this paper is to investigate the relationship between internal controls weakness and financial reporting quality and the effect of family ownership on the mentioned relationship in Iranian listed firms.Design/methodology/approachIn this way, the authors included the number of 139 firms from 2013 to 2017, of which 28 were family firms. The hypotheses are analyzed based on panel data and means comparison.FindingsThe results illustrated that weakness in internal controls has a significant negative relationship with financial reporting quality. In other words, internal controls weakness decreases the quality of financial reporting quality. Moreover, the results showed that being familial does not affect the aforementioned relationship.Originality/valueConsequently, there is no suitable criteria to distinguish family firms and there is a need to take them into serious consideration because very few studies have been conducted focusing on this issue in Iran, as it is considered an argumentative subject to be discussed in the Iranian market.
Comparison and Evaluation of Chemically Speciated Mobile Source PM2.5 Particulate Matter Profiles

ABSTRACT Mobile sources are significant contributors to ambient PM2 5, accounting for 50% or more of the total observed levels in some locations. One of the important methods for resolving the mobile source contribution is through chemical mass balance (CMB) receptor modeling. CMB requires chemically speciated source profiles with known uncertainty to ensure accurate source contribution estimates. Mobile source PM profiles are available from various sources and are generally in the form of weight fraction by chemical species. The weight fraction format is commonly used, since it is required for input into the CMB receptor model. This paper examines the similarities and differences in mobile source PM2.5 profiles that contain data for elements, ions, elemental carbon (EC) and organic carbon (OC), and in some cases speciated organics (e.g., polycyclic aromatic hydrocarbons [PAHs]), drawn from four different sources. Notable characteristics of the mass fraction data include variability (relative contributions of elements and ions) among supposedly similar sources and a wide range of average EC:OC ratios (0.60 ± 0.53 to 1.42 ± 2.99) for light-duty gasoline vehicles (LDGVs), indicating significant EC emissions from LDGVs in some cases. For diesel vehicles, average EC:OC ratios range from 1.09 ± 2.66 to 3.54 ± 3.07. That different populations of the same class of emitters can show considerable variability suggests caution should be exercised when selecting and using profiles in source apportionment studies.

Fostering Collaborative Learning with Mobile Web 2.0 in Semi-Formal Settings

Mobile Web 2.0 technologies such as: mobile apps, social networking sites and video sharing sites have become essential drivers for shaping daily activities and meeting learning needs in various settings. However, very few studies link mobile Web 2.0 to supporting collaborative learning in real-life problem solving activities in semi-formal contexts. A study of collaborative learning and mobile Web 2.0 usage practices in real-life problem solving activities was carried out with 18 participants recruited from a local faith based community club. Research data was gathered through observational studies, open-ended questionnaires, semi-structured interviews and by logging content captured on mobile devices. Data analysis examined learner demographics, social interactions and artefacts produced in activities. Results indicate that the choice and use of mobile Web 2.0 to support collaborative learning in semi-formal settings is based on the ways in which technological functions effectively support and enhance established social relations and practices.
Cooperative Control of Power System Load and Frequency by Using Differential Games

Electric power systems are evolving toward smart grids all over the world, which are generally regarded as the next-generation power systems with extensive application of advanced control, communications, and computation techniques. More and more distributed intelligent controllers will be employed in smart grids. Load frequency control (LFC) is a key issue in the traditional interconnected power systems, which constantly requires different control areas (CAs) to share the regulation burden of the CA that lacks regulation capacity by providing the power supports via the tie-line. Such a process imposes extra regulation costs on the helping CAs, for example, the wear and tear of generating units, which may result in the unfairness and the CAs' deviation from the LFC command. This situation becomes even more serious with the integration of intermittent renewable energy such as wind and solar power. In this paper, cooperative control by using differential games (DGs) is proposed as a possible solution to this problem. With a two-area and a three-area LFC models, a noncooperative equilibrium solution, and two cooperative equilibrium solutions with different time-consistency properties are derived. The case studies compare the proposed three DG-based LFC schemes with the traditional approaches based on proportional-integral control and the optimal control, and the results show that the cooperative control schemes allocate the regulation burden more rationally and ensure the CAs' sticking to the LFC command, which will be favorable to the stability of power system operation. The capability of conflict solution of DG-based cooperative control makes it a very promising scheme for smart grid control.
Spatiotemporal dynamics in the early stages of the 2009 A/H1N1 influenza pandemic

Epidemiology and public health planning will increasingly rely on the analysis of genetic sequence data. The ongoing influenza A/H1N1 pandemic may represent a tipping point in this trend, with A/H1N1 being the first human pathogen routinely genotyped from the beginning of its spread. To take full advantage of this genetic information, we introduce a novel method to reconstruct the spatiotemporal dynamics of outbreaks from sequence data. The approach is based on a new paradigm were ancestries are inferred directly rather than through the reconstruction of most recent common ancestors (MRCAs) as in phylogenetics. Using 279 A/H1N1 hemagglutinin (HA) sequences, we confirm the emergence of the 2009 flu pandemic in Mexico. The virus initially spread to the US, and then to the rest of the world with both Mexico and the US acting as the main sources. While compatible with current epidemiological understanding of the 2009 H1N1 pandemic, our results provide a much finer picture of the spatiotemporal dynamics. The results also highlight how much additional epidemiological information can be gathered from genetic monitoring of a disease outbreak.
A framework of students' reasons for using CMC media in learning contexts: A structural approach

Motivated by the increasing popularity of computer-mediated communication (CMC) media in university students' learning, this study employs a four-stage novel approach for analyzing and developing a structured hierarchy framework for students' usage of CMC media in learning contexts. First, media characteristics and the Uses and Gratifications (U&G) approach were adopted to understand student-specific reasons for using media. Second, a set of relevant data concerning the university students' reasons for using CMC media was collected by the Repertory Grid Interview Technique (RGT) and analyzed qualitatively using content analysis. The Interpretive Structural Modeling (ISM) technique was then used to develop a six-level hierarchical structural model of media use reasons. Finally, the cross-impact matrix multiplication applied to classification (MICMAC) technique was used to analyze the driver and dependence power for each media use reason and identify the hidden and indirect relationships among all reasons. The reasons related to students' use of CMC were classified as independent variables, linkage variables, and dependent variables. The study provides a validated typology of different clusters of interrelated students' reasons for using CMC media in learning contexts. The findings of this study will have significant implications and will be helpful for researchers, university policy-makers, instructors, and organizations in framing CMC technology implementation and use strategies. © 2011 Wiley Periodicals, Inc.
Myo-inositol, D-chiro-inositol, folic acid and manganese in second trimester of pregnancy: a preliminary investigation.

DESIGN AND PURPOSE The supplemental administration of myo-inositol, D-chiro-inositol, folic acid and manganese (MDFM) was tested in a prospective, randomized, double-blind, placebo controlled clinical trial, pilot study, to test the hypothesis that its supplemental administration in the second trimester of pregnancy would improve glucose and glycemic parameters and blood pressure. SUBJECTS AND METHODS Non-obese uniparous healthy pregnant women between 13th and 24th week of pregnancy were divided into two groups: group I, control group with placebo, and the group II, women in treatment with myo-inositol, D-chiro-inositol, folic acid and manganese. The main outcome measures were the comparative analysis of the parameters analyzed at time 0, after 30 days and 60 days; secondary outcome measure was the overall analysis of investigated parameters. RESULTS 24 women were allocated to receive MDFM and 24 the placebo. The two groups did not significantly differ for demographic, lipidic and glycemic parameter and blood pressure. After 30 days, significantly lower cholesterol (p = 0.0001), significantly lower LDL (p = 0.0013), lower TG (p < 0.0001) and lower glycemia (p = 0.0021) were observed all favoring group II. No significant difference was observed for HDL, diastolic and systolic blood pressure. After 60 days, significant difference was observed for cholesterol (p = 0.0001), LDL (p = 0.0001), HDL (p = 0.0001), TG (p = 0.0001), glycemia (p = 0.0064), all favoring the group treated with MDFM. No significant differences were observed for systolic (p = 0.12) and diastolic blood pressure (p = 0.42). When examining for overall differences between the two groups, a significant difference was observed for examined parameters at time 0 and at time 60; cholesterol (p = 0.0001), LDL (p = 0.0001), HDL (p = 0.047), TG (p = 0.0001) and glycemia (p = 0.019) were reduced in the MDFM group. A significant reduction was also observed in group II for systolic blood pressure after 60 days of intervention (p = 0.0092), but not for diastolic blood pressure (p = 0.29). CONCLUSIONS MDFM administration after 30 days in pregnancy improved glycemic and lipidic parameters, with significant gain after 60 days, without affecting diastolic blood pressure levels.
The perceptions of South African accounting practitioners on the post-implementation of IFRS for SMEs in an institutionalised environment

Orientation: Small and medium-sized entities (SMEs) play a crucial role in the South African economy. The financial reporting framework applicable to SMEs may contribute to the success of the SME. This study was exploratory in nature and followed an interpretive approach to seek an in-depth understanding of the application of the International Financial Reporting Standards for Small and Medium-Sized Entities (IFRS for SMEs) in South Africa. Research purpose: This article explores the perceptions of South African accounting practitioners regarding the post-implementation of the IFRS for SMEs in the South African SME sector. Motivation for the study: South African research on IFRS for SMEs is scarce. This study was designed to contribute to the scarce body of literature on IFRS for SMEs and will benefit both the South African and international accounting profession. Research approach/design and method: In-depth semi-structured interviews with 21 accounting practitioners were carried out during 2017 and 2018. An interpretive approach was adopted to analyse the data into themes providing the insight into the perceptions of South African practitioners. Main findings: Overall, there appears to be an approval of IFRS for SMEs. The uniformity associated with IFRS for SMEs is one of the significant advantages, while factors such as the age of the practitioners, the use of automated software systems and South African legislative requirements affect the relative merit of using the standard. Practical/managerial implications: The use of the interpretive style will assist professional accounting organisations, standard setters and regulators in understanding the various benefits and drawbacks of the IFRS for SME framework. Contribution/value-add: This article is the first to explore the in-depth views of accounting practitioners after IFRS for SMEs was adopted in South Africa. The article also highlights the challenges faced by accounting practitioners in developing economies that service SMEs.
The Role of Demandable Debt in Structuring Optimal Banking Arrangements

Demandable -debt finance by banks warrants explanation because it entails costs of bank suspension , liquidation, and idle reserve holdings. An explanation is developed in which demandable debt provides ince ntive-compatible intermediation where the banker has comparative adv antage in allocating investment funds but may act against the interests of uninformed depositors. Demandable debt attracts funds by giving depositors an option to force liquidation. Its usefulness in transacting follows from information-sharing between monitors and nonmonitors. (JEL G21)
Measure of E-Cash on Delivery Payment Convenience Option in the Context of Demonetisation and its Effect on Customer Loyalty

The rapidly changing business environment in India, particularly after demonetization, has made marketers understand the complex behaviour of consumers. Online retailers in India do not want to miss any opportunity to serve customers in a better way and enhance customer convenience. Since the Indian market is very dynamic, it is very important to understand the different factors affecting customer purchase decision; among these different factors, customer payment options are an important factor. Although online retailers offer several modes of payment, demonetization has changed the entire equation. This paper studies the measure of e-COD payment convenience scale, its validity, reliability and how it affects customer loyalty. Research methods like confirmatory factor analysis and structural equation modelling have been applied with the help of SPSS and AMOS.
