This paper addresses the problem of reactive power dispatch in a power system partitioned into several areas controlled by different transmission system operators. Previous research has shown that nearly optimal performance could be achieved in a time-invariant system by using a specific iterative decentralized control scheme with no information exchange. At each iteration of this scheme, every transmission system operator concurrently schedules its own control settings for the next iteration while representing the neighboring areas with external network equivalents. This paper focuses on some parameter tracking techniques to extend the range of application of the decentralized control scheme to time-varying systems, where the time-varying nature of the system is modeled as a succession of steady-state operating conditions with variation of the load demand. Those new techniques are evaluated in the context of IEEE 118 bus system partitioned into three control areas. [less ▲]

In this book the information relevant to fire design of steel structures is presented in a systematic way in seven chapters. Each Chapter begins with an introduction of various concepts to be covered and follows with detailed explanation of the concepts. The calculation methods as relevant to code provisions (in Europe, North America or other continents) are discussed in detail. Worked examples relevant to calculation methodologies on simple structural elements are presented. For the case of complete structures guidance on how analysis can be carried out is presented. Chapter 1 of the book is devoted to providing relevant background information to codes and standards and principles of fire resistance design. The chapter discusses the fire safety design philosophies, prescriptive and performance-based design fire safety design issues. Chapter 2 deals with basis of design and mechanical loads. The load combinations to be considered for fire design of structures, as per European and North American codes and standards, are discussed. Chapter 3 discusses the detailed steps involved in establishing the fire scenarios for various cases. Both Eurocode and North American temperature-time relationships are discussed. Procedures in this section allow the designer to establish the time-temperature relationships or heat flux evolutions under a specified design fire. Chapter 4 deals with steps associated in establishing the temperature history in the steel structure, resulting from fire temperature. The various approaches for undertaking thermal analysis by simple calculation models are discussed. Chapter 5 presents the steps associated for establishing the mechanical response of a structure exposed to fire. The possibilities for analysis at different levels: member level, sub-structure level and global level are discussed. Full details related to simple calculation methods for undertaking strength analysis at member level are presented. Chapter 6 is devoted to fire resistance issues associated with design of joints. The steps associated with the fire resistance of a bolted or a welded joint through simplified and detailed procedure are discussed. Chapter 7 deals with thermal and mechanical analysis through advanced calculation models. The procedures involved in the sub-structure analysis or global structural analysis under fire exposure is fully discussed. Case studies are presented to illustrate the detailed fire resistance analysis of various structures. Chapter 8 presents four design examples showing how a complex structure can be designed using the concept of element or sub-structure analysis. The book concludes with two Annexes which present some of the design information related to material properties and temperature profiles. Annex 1 focuses on thermal properties of structural steel and commonly used insulation materials and resulting temperature profiles in steel. Annex 2 focuses on mechanical properties of structural steel. [less ▲]

Bluetongue is a non-contagious disease that affects domestic and wild ruminants. Since its spreading to Northern Europe in 2006, this viral epizooty caused considerable economical losses on the ovine and bovine livestock. The biological vectors of the bluetongue virus (BTV) are biting midges belonging to the genus Culicoides. Many elements still remain unknown about their biology, physiology, ecology and distribution. This study shows that these biting midges are much more abundant on farm level than in the nearby meadows; these last ones nevertheless present a much more specifi c diversity. So possibility of migration between the meadow and the farm is voiced for the C. chiopterus and C. dewulfi species. Females are much more represented than males for the farm and the meadow alike. The physiology observation of these ones is realized throughout the study. [less ▲]

Low temperature epitaxial growth of group-IV alloys is a key process step to realize the advanced Si-based devices. In order to keep high growth rate below 600 $\,^ rc$C, trisilane (Si3H8) was used for their growth as an alternative Si precursor gas. Then, we compared the use of Si3H8 versus SiH4 for Si1−xGex growth in H2 and N2 as carrier gas by low temperature chemical vapor deposition. By using Si3H8 and controlling GeH4 flow rate, Si1−xGex growth with high growth rate and wide range of Ge concentration has been achieved compared to SiH4-based process. The growth rate and Ge concentration in Si1−xGex with Si3H8 grown at 600 $\,^ rc$C ranged from 11 to 74 nm/min and from 0 to 40%, respectively. The obtained growth rates with Si3H8 are between 1.5 and 6 times higher than for SiH4 at a given growth condition. Si3H8-based in-situ B- and C-doped Si1−xGex growth with high growth rate was also demonstrated [less ▲]

La neuropsychologie de l’enfant concerne un champ d’étude relativement récent et en même temps très vaste. Le but de cet ouvrage est de fournir une vue d’ensemble des connaissances scientifiques qui se sont accumulées au cours de ces dernières années, et ceci pour les principales fonctions cognitives ainsi que les populations les plus fréquemment examinées en neuropsychologie de l’enfant, en passant des troubles développementaux avec ou sans cause cérébrale et génétique clairement définie aux lésions acquises telles que le traumatisme crânien ou l’accident vasculaire cérébral. Une première série de chapitres situera les troubles cognitifs dans le cadre de la dynamique développementale qui caractérise la neuropsychologie de l’enfant, permettant de fournir une compréhension la plus complète possible des difficultés constatées. Une deuxième série de chapitres sera de nature davantage syndromique, en présentant les troubles cognitifs associés aux traumatismes crâniens, aux troubles épileptiques, aux principaux syndromes génétiques ainsi qu’à d’autres troubles développementaux tels que les troubles attentionnels avec ou sans hyperactivité et l’autisme. Dans les cas pertinents, les principaux outils d’évaluation disponibles seront développés et des pistes rééducatives discutées. [less ▲]

Background. The Belgian Transplant Coordinators Section is responsible for the yearly data follow-up concerning donor and transplantation statistics in Belgium and presents herein a 10-year overview. Methods. The procurement and transplant statistics were compared between 2 periods: Period 1 (P1, 1997–2005) versus Period 2 (P2, 2006–2007). Results. The kidney and liver waiting lists (P1 vs P2) showed an overall decrease for a period of 2 consecutive years in P2; kidney ( 170 patients; 18%), and liver ( 83 patients; 34%). All other waiting lists (heart, lung, pancreas) remained stable. Mean ED further increased (P1 vs P2); 229 (P1) versus 280 (P2, 22.27%). Non–heart-beating donors were significantly ( 288%) more often procured in P2. Mean donor age was 37.9 17.8 years (P1) versus 46.5 19.9 years (P2), and mean organ yield per donor was 3.48 1.7 (P1) versus 3.38 1.8 (P2). Overall transplant activity per million inhabitants increased 21.1%. Conclusion. For 2 consecutive years, the Belgian statistics showed significantly increased donor activity with an impact on waiting list dynamics and transplantation. The mean organ yield per donor was not influenced despite an increased average age and change in reason for death. [less ▲]

The objective of this paper is to examine nonlinear normal modes and their bifurcations in cyclic periodic structures. The nonlinear normal modes are computed using a numerical technique that combines shooting and pseudoarclength continuation. Unlike perturbation techniques, the resulting algorithm can investigate strongly nonlinear regimes of motion. This study reveals that modal interactions may occur without necessarily having commensurate natural frequencies in the underlying linear system. In addition, a countable infinity of such modal Q2 interactions are shown to exist in the system. [less ▲]

Bovine ghrelin, a 27 amino acid pepticle, has been identified in oxyntic glands of the abomasum. It is an endogenous ligand for growth hormone secretagogue receptor and stimulates food intake and growth hormone secretion. The bovine GHRL gene was completely sequenced and consists of five exons and four introns. Like mouse and human GHRL genes, we found that the bovine GHRL gene also contains a first non-coding exon of 21 bp. The bovine GHRL gene codes for 116 amino acid pepticle named preproghrelin which contains the ghrelin pepticle and another pepticle similar to obestatin. Sequence analysis revealed eight polymorphisms, which are located in the non-coding sequence of the gene. [less ▲]
