ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The RCC TTG initiated task TT-49 to generate a standard for the transport of serial streaming telemetry (TM) over the Internet Protocol (IP). An ad hoc committee was activated comprised of Range and vendor participation to develop this standard. This paper will address the progress of the standard, the use of commercial standards, and the benefits to the ranges. The early meetings focused on developing the packet structure; the preliminary results will be presented along with the latest status on the RCC approval cycle.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / A fiber optic event timing system was developed for the High Speed Test Track at Holloman Air Force Base, Alamogordo, NM. The system uses fiber optic sensors to detect the passage of rocket sleds by different stations along the track. The sensors are connected by fiber optic cables to an electronics package that records the event time to a resolution of 100 nanoseconds. By use of a GPS receiver as the timebase, the event time is stored to an absolute accuracy of 300 nanoseconds. Custom VMEbus boards were developed for the event timing function, and these boards are controlled by a programmable high speed sequencer, which allows for complicated control functions. Each board has 4 electro-optic channels, and multiple boards can be used in a VMEbus card cage controlled by a single board computer. The system has been tested in a series of missions at the Test Track.

Timing och sväng är begrepp som återkommit frekvent i min musikutbildning. Min upplevelse är att ämnet är viktigt, men att det samtidigt saknas forskning på området. Studien syftar till att få en djupare insikt i hur pianopedagoger definierar begreppen timing och sväng samt hur de ser på undervisning när det gäller dessa. Jag är intresserad av att hitta didaktiska redskap och metoder för att på ett konkret sätt kunna tillämpa timing och sväng i pianoundervisningen. Undersökningen genomfördes med hjälp av en kvalitativ intervju-form där jag intervjuade fyra pianopedagoger, med inriktning jazz, verksamma på olika musikhögskolor och konservatorier. Resultatet visar, enligt respondenternas tolkning, att timing och sväng spelar en viktig roll i musiken i stort. För att komma åt detta i pianoundervisningen presenteras olika redskap. Viktiga aspekter för att spela svängigt pianospel är exempelvis kopplingen till kroppen, dynamik och underdelningar. Resultatet visar också att timing och sväng handlar om att göra musiken levande.

With aggressive technology scaling, within-die random variations are becoming the most dominant source of process variations. Gate-level statistical static timing is becoming a widely accepted approach as an alternative to static timing analysis. However, statistical timing approaches lack good models for handling timing variations due to within-die random variations. Before performing statistical timing analysis on a design or System On Chip (SoC), the cells in the library are pre-characterized for delay as well as constraints due to these random variations. This is referred to as statistical characterization of the cells. The major contribution of this dissertation is the development of novel techniques for statistical characterization and optimization of cells. The methods couple the knowledge of circuits along with the significant factor analysis methods to compute the sensitivities, to perform statistical timing and to perform sensitivity-aware cell optimizations. The first contribution of this dissertation is a statistical delay characterization method developed for computing delay sensitivities of standard cells considering both global and mismatch process variations. In addition to the cells being characterized for delay, the sequential cells are characterized for timing constraints like setup and hold time constraints. The second contribution of this dissertation addresses the problem of constraint sensitivity characterization in sequential cells. Block-based statistical timing approaches lack accurate consideration of the impact of slew variations on both delay and arrival time variations. Specifically, the delay variations due to within-die random variables (mismatch variables) result in a slew-based correlation during timing propagation. Handling within-die random variations more accurately during statistical timing propagation is the topic of the third contribution of this dissertation. Clock networks are more prone to these within-die random variations and can result in significant clock-skew variations. In the fourth contribution, a timing margining methodology is presented that accurately accounts for the clock skew variations in a timing sign-off flow. Typically, the standard cells are designed very early in the design cycle and long before the process reaches production maturity. Any subtle improvements to reduce variability in standard cells can improve parametric yield significantly. Statistical characterization of cells for timing provides a key baseline for understanding the circuit behavior due to different sources of variation. The sensitivity information can also help increase yield by reducing the variability during the circuit design itself. The final contribution in the dissertation addresses this by defining key cell and device criticality metrics. A sensitivity-aware standard cell layout optimization is demonstrated using the proposed criticality metrics. / text

The aim of this study was to investigate how timing training by Interactive Metronome ® (IM) affects motor timing and rhythmicity in soccer players. Twenty-four female soccer players (age 19 ± 2.8) participated, and were randomly assigned to either a control or an IM training group. All participants took part in a functional magnetic resonance imaging (fMRI) session before the start of the training period, to find out what brain areas are activated during different tempos. The fMRI outcomes indicate that some of the active areas are the inferior parietal cortex (BA 40), frontal/SMA and precentral cortex and postcentral (BA 6) and inferior frontal cortex (BA 45). Pre- and post-measurements of motor timing deviation and variability was made. The result shows that after four week of IM training a significant improvement of motor timing was found for the IM group in comparison to the control group. The findings indicate that timing training can improve timing ability in healthy sport perpetrators.

The main aim of this thesis is to understand the extent to which intraspecific variation in developmental event timing might provide the raw material from which heterochronies may originate. To this end I studied the timing of a suite of both morphological and physiological events in the embryonic development of Radix balthica, a species of aquatic snail known to exhibit event timing variation during the embryonic period (Tills et al. 2010; Rundle et al. 2011) and that sits within an evolutionary clade, in which extensive heterochrony has been documented (Smirthwaite et al. 2007). I found that variation in embryonic developmental event timing within R. balthica is pervasive (Chapters 2 - 5) and distributed primarily at low (inter-individual and egg mass), rather than high (population) biological levels (Chapter 3). This variation also appears to have a genetic basis (Chapter 2) and to be heritable (Chapters 4 and 5). Examination of the development of function in the cardiovascular (CV) system in Chapter 5 also revealed extensive variation, including differences between egg masses in the timing of aspects of this development, and differences between populations in the rates of change in heart rate during different phases of ontogeny. Variation in CV development also had effects on life history, which suggest that altered embryonic development might have implications for Darwinian fitness (Chapter 5). This thesis demonstrates that intraspecific variation in developmental event timing represents a fundamental link between ontogeny and phylogeny and that study of altered timing at the inter-individual level provides the opportunity to address questions concerning its evolvability and implications.

The Large Observatory For x-ray Timing (LOFT) is a mission concept which was proposed to ESA as M3 and M4 candidate in the framework of the Cosmic Vision 2015-2025 program. Thanks to the unprecedented combination of effective area and spectral resolution of its main instrument and the uniquely large field of view of its wide field monitor, LOFT will be able to study the behaviour of matter in extreme conditions such as the strong gravitational field in the innermost regions close to black holes and neutron stars and the supra-nuclear densities in the interiors of neutron stars. The science payload is based on a Large Area Detector (LAD, > 8m(2) effective area, 2-30 keV, 240 eV spectral resolution, 1 degree collimated field of view) and a Wide Field Monitor (WFM, 2-50 keV, 4 steradian field of view, 1 arcmin source location accuracy, 300 eV spectral resolution). The WFM is equipped with an on-board system for bright events (e. g., GRB) localization. The trigger time and position of these events are broadcast to the ground within 30 s from discovery. In this paper we present the current technical and programmatic status of the mission.

De acordo com a teoria de equity market timing, as companhias tendem a emitir ações ou dívidas de modo a explorar janelas de oportunidade e esse comportamento é um determinante significativo da estrutura de capital das empresas, reflexo das decisões de financiamento. Com base nessa assertiva e nas evidências recentes, esta dissertação investiga a ocorrência de equity market timing na decisão de emissão primária de ações (IPO e Follow-on) no mercado de capitais brasileiro. Em um primeiro momento, analisaram-se os determinantes da estrutura de capital das companhias brasileiras, com base em variáveis comuns na literatura: índice market-to-book, tamanho, tangibilidade, rentabilidade e setor. Mais tarde, para averiguar a existência do comportamento de market timing na decisão de emitir ações, utilizou-se a relação dos retornos anormais, antes e após a emissão, com o volume total de capital levantado por meio da oferta desses títulos, além da quantidade de ações que a empresa emitiu e o preço inicial de negociação, medidas relativas utilizadas por Alti (2006). A amostra analisada leva em conta características setoriais e compreende 123 empresas de capital aberto que emitiram novas ações na BM&FBOVESPA entre 2004 e 2015, somando 165 emissões primárias durante esse período. Foram utilizadas análises descritivas de dados, testes de diferença de médias e regressões lineares para prover evidências da ocorrência desse fenômeno. Os resultados indicam que mais da metade das emissões de ações no Brasil ocorre nos meses que antecedem o prazo máximo de divulgação dos demonstrativos contábeis das empresas, e que 75% das emissões aconteceram depois de retornos anormais positivos. Ademais, as empresas que tiveram retornos anormais negativos depois da emissão de ações foram as que captaram mais recursos por essa via de financiamento, indo a favor da prática de equity market timing na decisão de emissão de ações no mercado brasileiro. Destaca-se, ainda, a constatação de que esse comportamento oportunista está mais claramente ligado à oferta inicial de ações (IPO), ou seja, quando a empresa utiliza essa fonte de financiamento pela primeira vez do que quando a emissão é subsequente (Follow-on), além das evidências de que o setor tem papel importante no comportamento de market timing dos gestores, indicando que as empresas de um mesmo ramo setorial tomam decisões semelhantes com a finalidade de explorar janelas de oportunidades possivelmente relacionadas aos seus respectivos setores. / According to the equity market timing theory, companies tend to issue stocks or debts in order to explore windows of opportunity, and this behavior is a significant determinant of the capital structure of companies, which reflects from financing decisions. Based on this assertion and on recent evidence, this dissertation investigates the occurrence of equity market timing in the decision of primary issuance of shares (IPO and Follow-on) in the Brazilian capital market. First, determinants of the capital structure of Brazilian companies were analyzed, based on common variables in the literature: market-to-book ratio, size, tangibility, profitability and industry. Later, in order to determine the occurrence of market timing behavior in the decision to issue shares, it was investigated the relation of abnormal returns - both before and after the issue - with the total volume of capital raised through securities\' offers and also the quantity of shares issued by the company and the initial trading price, relative measures used by Alti (2006). The analyzed sample takes into account industrial characteristics and comprises 123 public companies that issued new shares on BM&FBOVESPA between 2004 and 2015, resulting in to 165 primary issues during this period. Descriptive data analyzes, mean difference tests and linear regressions were used to provide evidence of the occurrence of this phenomenon. The results indicate that more than half of Brazil\'s equity issues occur in the months leading up to the maximum disclosure period of the companies\' financial statements, and that 75% of the issues occurred after abnormal positive returns. In addition, the companies that had negative abnormal returns after the issuance of shares were the ones that captured more resources through this financing channel, favoring the practice of equity market timing in the decision to issue shares in the Brazilian market. It should also be pointed out that this opportunistic behavior is more clearly linked to the initial public offering (IPO), that is, when the company uses this source of financing for the first time than when the issue is secondary (Follow- on). Also, there is evidence that the industry plays an important role in the manager\'s market timing behavior, indicating that the companies belonging to a same industry make similar decisions with the purpose of exploring windows of opportunities that possibly related to their respective industries.
