Full textAbstract:
Meta-analysis has become a foundation of scientific inquiry. It is used to statistically integrate the findings of many studies to come to generalizable conclusions. Unfortunately, in some cases, the number of studies available for the analysis can make the meta-analysis process extremely difficult and lengthy. The current study attempted to alleviate this problem by investigating the effects of random sampling of the studies used in the analysis in recently published meta-analyses to determine if a subsample of studies could produce accurate results. In the process, the characteristics of recent meta-analyses were investigated, as well as the percentage of randomly sampled studies that is needed to produce accurate moderator findings. Results of this investigation provide preliminary support for the use of random sampling in medium and large-scale meta-analyses, or analyses in which a medium (35 or more) to large number (91 or more) of studies fit the analystâs inclusion criteria. Random sampling was able to reproduce the main effect sizes found in these types of meta-analyses. The use of random sampling to replicate the results of meta-analyses involving moderators, however, was only successful in large scale analyses. It is hoped that these results will encourage the use of random sampling in future meta-analyses by providing guidelines for its use, as this procedure can drastically reduce the amount of work required.

Full textAbstract:
Traditional theories of vision assume that object segregation occurs before access to object memories. Yet, behavioral evidence shows that familiar configuration is a prior for segregation, and electrophysiological experiments demonstrate these memories are accessed rapidly. A behavioral index of the speed of access is lacking, however. Here we asked how quickly behavior is influenced by object memories that are accessed in the course of object segregation. We investigated whether access to object memories on the groundside of a border can slow behavior during a rapid categorization task. Participants viewed two silhouettes that depicted a real-world and a novel object. Their task was to saccade toward the real-world object as quickly as possible. Half of the nontarget novel objects were ambiguous in that a portion of a real-world object was suggested, but not consciously perceived, on the groundside of their borders. The rest of the nontargets were unambiguous. We tested whether saccadic reaction times were perturbed by the real-world objects suggested on the groundside of ambiguous novel silhouettes. In Experiments 1 and 2, saccadic reaction times were slowed when nontargets were ambiguous rather than unambiguous. Experiment 2 set an upper limit of 190 ms on the time required for object memories in grounds to influence behavior. Experiment 3 ruled out factors that could have produced longer latencies other than access to object memories. These results provide the first behavioral index of how quickly memories of objects suggested in grounds can influence behavior, placing the upper limit at 190 ms.

Full textAbstract:
Fescue toxicosis is problematic for ruminant livestock, causing weight loss and low productivity when fed endophyte-infected forages. Complete underlying mechanisms of toxicosis are unknown therefore; the objective of the study was to determine if ruminally dosed ergot alkaloids impact rumen motility. Cannulated steers were pair-fed a forage diet and ruminally dosed with endophyte-free (E-) or endophyte-infected (E+) tall fescue seed. An 8-h period of rumen motility collection began 4-h after feeding by monitoring pressure change via a wireless telemetry and transducer system. In experiment 1, steers were paired by weight and assigned to E- or E+ treatment. Overall, E+ steers had more frequent contractions. On d 7 - 9, both treatments had lower frequencies and E- steers had greater amplitude of contractions, which corresponded with decreased DM intake. In experiment 2 steers remained in pair, but switched treatment. During the 57 d E+ steers received titrated levels of ergovaline + ergovalinine. There was no difference between treatments for frequency or amplitude of contractions, but increasing dosage, decreased frequency (d 1 - 44) and amplitude, coinciding with lower DM intakes. Alteration in rumen motility associated with changes in intake may be responsible for the decreased productivity in ruminants consuming E+ forages.

Full textAbstract:
Volumetric Lighting is a collective term for visual phenomena that occur due to how light interacts inside so-called participating media, and it accounts for many recognizable effects such as fog or light shafts. Because it isvery computationally expensive, it has been an importantproblem within computer graphics to calculate volumetriclighting, both accurately and efficiently. Ray Marching is a technique that has been used extensively in non real-time applications to compute volumetriclighting and has recently been adapted for real time applications by use of the GPU. In this thesis we implement andevaluatevolumetric ray marching with ordered dithering. The results show how ordered dithering yields significant performance improvements, retaining high quality while lowering the number of samples. We conclude that with ordered dithering, volumetric ray marching is a suitable approach for real time volumetric ray marching on the GPU and we discuss both important additional optimizationsand how ordered dithering will likely remain important in future ray marching implementations.Volumetriskt ljus är en term som beskriver visuella fenomen som uppstår från hur ljus interagerar inuti material som kan bära ljus. Hur ljuset absorberas eller ändrar riktning då det färdas igenom material ger upphov till många bekanta fenomen såsom dimma, moln eller eld. Eftersom volumetriskt ljus är dyrt att beräkna så har det varit ett viktigt problem inom datorgrafik hur man effektivt simulerar denna typ av ljustransport. Ray Marching är en metod som har använts mycket inom bland annat filmindustrin där man inte har en hård gräns på beräkningstiden, men metoden har med hjälp av grafikkortets parallelliseringsförmåga också börjat appliceras för realtidsapplikationer såsom datorspel. I denna rapport så utforskar vi en optimeringsmetod till grafikkortsbaserad ray marching som kallas för ordered dithering. Resultaten visar hur optimeringsmetoden ger stor prestandaförbättring genom att placera samplingspunkter mer effektivt, utan signifikant försämring av kvalité. Resultaten styrker hur den valda algoritmen är en lämplig algoritm för att åstadkomma volumetriskt ljus i realtid. Vi diskuterar också hur optimeringsmedoten troligtvis även i framtiden kommer spela en viktig roll i att nå acceptabel prestandainom grafikkortsbaserad ray marching.

Full textAbstract:
Guiding arriving flights through congested terminal airspace has always been a challenge. As traffic builds up, controllers must often move traffic away from the airport until they can bring those flights in for landing, causing inefficiencies. A widespread implementation of Continuous Descent Approach (CDA) would result in significant reductions in environmental impact and airline operating costs, however, a significant barrier to system wide CDA implementation is the difficulty to merge and space flights so that the CDA is flown safely. The en route metering essentially allows flights to absorb any necessary arrival delays en route, with transition to the terminal area in a pre-planned sequence. When delays would be imposed, the priority of landing would be based on the calculated time of arrival for each flight at the last metering fix, using a First-Come-First-Served policy. The spacing between successive arriving flights needs to be sufficient to allow for other flights downstream to merge into the overall flow while maintaining the minimum required separation according to the applicable rules. This work describes the fundamental design of a decision-support tool and procedures for CDA in the Sao Paulo Terminal Radar Approach Control (SP-TRACON) with flight spacing based on Required Time of Arrival (RTA) at a metering fix. A linear programming model was used to establish required time of arrival at TRACON entry points to provide adequate separation on final approach following the Standard Terminal Arrival Routes (STARs). For this purpose, typical actual traffic data approaching to airports in the SP-TRACON were used to apply the sequence model and evaluate the potential benefits on throughput and delays for Sao Paulo - Guarulhos airport. Using the ATFM methodology developed in this work, the general delays applied to the traffics of the two selected days were 53.5% and 55.1% lower than the delays observed with ATFM measures used by air traffic controllers. For the peak hours considered, the methodology provided 25.5% and 30.1% delay reduction. The air traffic controllers role in the process and workload reduction is also discussed.

Full textAbstract:
For many years, colleges of engineering across the nation have required that a foundational set of courses be completed for entry into upper division coursework or into a specific engineering major. Since 1998, The Dwight Look College of Engineering at Texas A&M University (TAMU) has required that incoming first-time enrolling students complete a Core Body of Knowledge (CBK) with specific cumulative grade points required for specific majors. However, considerations of the time to completion of coursework and other student characteristics and academic factors have not been taken into consideration by TAMU, like most institutions. The purpose of this study is to determine for first year engineering students at TAMU the relationship of gender, ethnicity, engineering major, unmet financial need, cumulative grade point average, and total transfer hours on time to completion of CBK courses. The results of the analysis showed that cumulative grade point average (CGPA) had the strongest relationship to completion of CBK of any independent variable in this study. Statistical significance was found for the following variables in this study: CGPA, gender, ethnicity, and unmet financial need. For the study's variable of major, statistical significance was found for Chemical, Electrical, and Computer Engineering majors. The one variable in this study that did not show statistical significance in relation to time to completion of CBK was transfer credit. Findings with implications for recruitment and retention of underrepresented in engineering is a statistical significance indicating that on average females are taking less time than males to complete CBK. The conclusion from the study is that efforts to attract more women into engineering have merit as do programs to support underrepresented students in order that they may complete CBK at a faster pace. Further study to determine profiles of those majors where statistical significance was found for students taking a greater or lesser amount of time for CBK completion than the mean is recommended, as is ongoing data collection and comparison for current cohorts of engineering majors at TAMU.

Rydell, Sofia. "Arrival and departure manager cooperation for reducing airborne holding times at destination airports." Thesis, Cranfield University, 2011. http://dspace.lib.cranfield.ac.uk/handle/1826/8022.
Full textAbstract:
This thesis addresses the possibility of using a delay-on-ground concept in which flights with less than 1 hour flying time (often referred to as pop-up flights) absorb their arrival sequencing delay at the departure gate by being issued their Arrival Manager (AMAN)-scheduled time as a Required Time of Arrival (RTA) that is inserted into the Flight Management System (FMS). Due to their short duration these flights are currently often inserted into the AMAN sequence shortly before Terminal Manoeuvring Area (TMA) entry and thereby often need to absorb their arrival sequencing delay in the inefficient manner of airborne holding or vectoring close to the arrival airport. The literature review examines current operational procedures of AMANs and Departure Managers (DMANs), the current FMS RTA function and live trials in which the delay-on-ground concept was tested in real operations. A case study airport in Europe that has potential to benefit from the concept is identified. The performance of the delay-on-ground concept for the case study airport is then assessed by performing 180 fast-time Monte Carlo simulation runs. For each run the arrival flow to the case study airport and the departure flows from two medium-sized airports from which the pop-up flights originate are simulated. Each run represents an operational day and variations in departure/arrivals time is put into the timetables to simulate the variation in actual departure/arrival times resulting from operational factors normally encountered in day-to-day operations. An algorithm is written in Matlab to simulate an AMAN-DMAN cooperation in which pop-up flights are locked to the required departure times to meet their RTAs. It is shown that a significant reduction in airborne delay time and fuel consumption can be achieved at the case study airport by using the concept. It is also shown that it is possible to ensure that the pop-up flights depart at the required times to meet their RTAs without negatively affecting the departure sequences.

Full textAbstract:
Mechanical Design Mast & Wall Mounted Enclosures is one out of five units within Ericsson AB, Network and Enclosure Solutions. The department develops mast and wall mounted products for Radio Base Stations and is responsible for the Remote Radio Unit (RRU), one out of two main units in a main remote radio base configuration. The RRU is designed to be located near the antenna to reduce feeder loss and power use. There are high demands for mast and wall mounted telecommunications products and the handling and installation of the products are key features to meet technical requirements. These operations are not always so intuitive why the product documentation is very important information. Occasionally these instructions are not fully followed. The aim of the master thesis was to analyze how the design of an RRU and the mounting equipment affects the handling and installation of the product, and show that by designing for usability enhance the intuitive sense of how to perform the installation. The thesis follows a user centered design (UCD) process, including four main steps; specify the context of use, specify requirements, create design solutions and evaluate designs , which keep the user in focus through the whole work. The first two steps were done by information gathering and a usability analysis of the RRU. This part contained the handling and installation of the whole RRU, while the development part would only focus on the mounting equipment. Recommendations for future design of RRU‟s regarding usability aspects have been documented. Based on the analysis requirements for the development phase was set up. The most prominent requirements were to design a solution that did not contain loose details such as nuts and bolts, and that it had to be backward compatible to fit elder models. A mounting equipment design was developed and a prototype was produced in order to evaluate the design. Feedback on the design was collected from a usability practice with Ericsson engineers. The final solution of the new mounting equipment is designed to use the same components for both mast- and wall configurations. The design consists of three main components which are all used for mast mounting and where two of the components are used for wall mounting. The design depends on the manufacturing possibilities of extruded aluminum and bent stainless steel as well as on the usability requirements. The final design solution have been documented in this report and submitted in CAD-files to Ericsson.Mechanical Design Mast & Wall Mounted Enclosures är en utav fem avdelningar inom Ericsson AB, Network and Enclosure Solutions. Avdelningen utvecklar mast- och väggmonterade produkter för radiobasstationer och är ansvarig för den radiospecifika enheten, RRU‟n, som är en av två huvudenheter av en Main Remote basstation. RRU‟n är konstruerad för att placeras i närhet av antennen för att reducera förluster i kablarna. Det finns högt satta krav på mast- och väggmonterade telekom-produkter och hanteringen och installationen av dem är nyckelfunktioner för att klara de satta kraven. Produktinformationen är en viktig del av produkten där det framgår hur den skall hanteras och installeras, vilket annars inte alltid är så intuitivt. I vissa fall finns dock inte dokumentationen tillgänglig. Syftet med examensarbetet var att analysera hur konstruktionen av RRU‟n samt mast- och väggfästet påverkar användarvänligheten under hantering och installation, samt visa att genom att designa utifrån användarvänlighet förbättra den intuitiva känslan av hur man utför installationen. Arbetet följde en process med fokus på användaren (User Centered Design) med fyra huvudsteg; specificera användarsambanden, specificera kraven, skapa designlösningar och utvärdera modeller. De första två stegen utfördes genom informationssökning samt genom en användaranalys av RRU‟n och inkluderade hela RRU‟n samt fästanordningen, medan den andra delen av arbetet enbart fokuserade på fästanordningen. Problemområden angående produkterna och rekommendationer för framtida design av en RRU är sammanställda. Krav gällande användarvänlighet vilka baserades på analysen fastställdes. De mest framträdande kraven var att skapa en lösning som inte innehöll lösa detaljer som skruvar och muttrar, och att lösningen måste vara bakåtkompatibel för att passa äldre modeller av RRU‟er. Ett nytt mast- och väggfäste utvecklades och en prototyp tillverkades för att kunna utvärdera designen. En användarövning tillsammans med anställda ingenjörer på Ericsson genomfördes för att erhålla feedback. Den slutliga lösningen av fästanordningen är designat utifrån möjligheten att använda samma komponenter för både mast- och vägginstallation. Produkten består av tre huvudkomponenter varav alla tre används vid mastmontage men enbart två används vid väggmontage. Designen är anpassad efter tillverkningsmöjligheterna av extruderad aluminium och bockad rostfri stålplåt, samt satta användarkrav. Det slutliga konceptet finns dokumenterat i denna rapport samt överlämnat till företaget i CAD-filer.

Full textAbstract:
There is a need for a fuel-optimal required time of arrival (RTA) mode for aircraft flight management systems capable of enabling controlled time of arrival functionality in the presence of wind speed forecast uncertainty. A computationally tractable two-stage stochastic algorithm utilizing a data-driven, location-specific forecast uncertainty model to generate forecast uncertainty scenarios is proposed as a solution. Three years of Aircraft Communications Addressing and Reporting Systems (ACARS) wind speed reports are used in conjunction with corresponding wind speed forecasts from the Rapid Update Cycle (RUC) forecast product to construct an inhomogeneous Markov model quantifying forecast uncertainty characteristics along specific route through the national airspace system. The forecast uncertainty modeling methodology addresses previously unanswered questions regarding the regional uncertainty characteristics of the RUC model, and realizations of the model demonstrate a clear tendency of the RUC product to be positively biased along routes following the normal contours of the jet stream. A two-stage stochastic algorithm is then developed to calculate the fuel optimal stage one cruise speed given a required time of arrival at a destination waypoint and wind forecast uncertainty scenarios generated using the inhomogeneous Markov model. The algorithm utilizes a quadratic approximation of aircraft fuel flow rate as a function of cruising Mach number to quickly search for the fuel-minimum stage one cruise speed while keeping computational footprint small and ensuring RTA adherence. Compared to standard approaches to the problem utilizing large scale linear programming approximations, the algorithm performs significantly better from a computational complexity standpoint, providing solutions in fractional power time while maintaining computational tractability in on-board systems.

Full textAbstract:
Warfarin, the most commonly prescribed anticoagulant, is principally metabolized by cytochrome P450 2C9 which functions by inhibiting the Vitamin K epoxide reductase. Genes CYP2C9 and VKORC1 code for these two proteins, respectively. CYP2C9 and VKORC1 exhibit genetic polymorphisms that have been shown to affect warfarin response and favorably facilitate warfarin dosing and improve clinical outcomes. However, none of these studies have involved populations from sub-Saharan Africa where the potential benefit of optimal dosing and reduced complications is greatest. Therefore, the thesis describes a study designed to investigate the role of genetic variations in CYP2C9 and VKORC1 on the time taken to reach a stable therapeutic international normalized ratio (INR) and warfarin dose required to maintain a therapeutic INR. This was a cross-sectional study of patients on warfarin to determine the relationship between genetic polymorphism in CYP2C9 and VKORC1 amongst black and mixed ancestry South Africans and clinical surrogates of warfarin metabolism. Medical records were accessed to determine time to INR and warfarin doses. DNA was extracted from blood samples, and genotyping for polymorphism in CYP2C9 (*2,*3,*8,*11) and VKORC1 (1173C>T, 1639G>A, 3730G>A) was accomplished by PCR-RFLP, Sanger sequencing and iPlex Mass Sequencing. Our results show that the genetic profile of CYP2C9 and VKORC1 differs between Black Africans (BA) and their Mixed Ancestry (MA) counterparts. VKORC1-1639AA genotype was observed at frequencies of 0.11 and 0.01 in the MA and BA, respectively. Time to stable INR was not influenced by CYP2C9 and VKORC1. Furthermore, compared to known genetic polymorphisms in these genes from population out of Africa, both qualitative and quantitative differences were observed. Finally, we found that VKORC1 genetic variation significantly affected the doses of warfarin in MA but had no effect in BA. These results suggest that further research in this area is warranted, and that it will be important to include populations from sub-Saharan Africa in future if the potential to develop personalized algorithms which integrate pharmacogenomics to assist with effective warfarin dosing and prevention of warfarin related complications is to be realized.

Full textAbstract:
Music CompositionD.M.A
My final project for the D.M.A. in composition consists of a Requiem Mass honoring the victims of the Iraqi war, a conflict that has stirred public debate since the invasion of Iraq in 2003. It is not meant as a political statement; rather, it is intended as a tribute in the broadest sense--not only for the combatants who lost their lives, but also for the innocent citizens caught in the cross-fire, all the families left in grief, and the returning soldiers whose lives were altered if not shattered by the experience of war. It speaks to the devastating toll war has on society in general. The Requiem lasts approximately 56 minutes. Except for the Sanctus, the seven movements of the work are all performed contiguously. It is scored for mixed chorus; SSAATBB, a solo, coloratura soprano, solo tenor and orchestra (3333 2431, 2 harps, percussion and strings). Mass for a Time of War reflects a broad array of stylistic impulses from the medieval through the present day, all the while transcending the boundaries of the various musical gestures and resources. These influences include: Schoenberg's signature hexachord pair (012569) (013478), the tone row from Webern's Op. 21 Symphony (1928), Charles Ives's The Unanswered Question (1906), Stravinsky's Requiem Canticles (1966), Messiaen's Quartet for the End of Time (1941), Franz Liszt's Via Crucis (LW J33) and the Kyrie from Haydn's Mass in C major, Paukenmesse (Hob. XXII: 9). Techniques of contrafactum, serialism, including a section of total serialization as well as an aleatoric passage, are of structural importance in the work. Several new compositional methods developed for the Credo include the use of a matrix multiplier on rhythmic and tone rows to produce a new row--albeit a tonal one--and a procedure the author calls "rhythmic resonances." In Mass for a Time of War, texts and chants from the Missa pro defunctis [Mass for the Dead] are interwoven with Czeslaw Milosz's poem Meaning, and serve as structural scaffolding throughout. The choices of additional texts and what the author terms "musical subtexts" that surround the scaffolding of the Latin are selected and positioned to heighten the unfolding narrative. The texts from the Mass for the Dead anchors the Requiem, while the emotional thrust is guided by Milosz's Meaning. Although the Latin texts are deeply religious, they have been taken from their familiar context by aligning them with prose and poetry. It was not intended to remove their religious connotations, but to instead expand their significance to a metaphoric stature. Additional texts include Emily Dickinson's stark poem on death, LXXVI, several lines from Rainer Maria Rilke's The Ninth Duino Elegy, texts from Eugene O'Neill's Mourning Becomes Electra, The Red Badge of Courage by Stephen Crane, Dexter Filkin's The Forever War, texts in both the Ancient Greek and English translation of Homer's Iliad, Erich Maria Remarcque's All Quiet on the Western Front, several texts from The New York Times Magazine and New Yorker Magazine articles, as well as the names of victims on both sides of the war. The arrangement of the texts and subtexts are consciously meant to imitate "cut-up" poetry or fiction, also called découpage, a form that takes small sections of words from existing poems as well as additional texts, such as those from newspapers and magazines and rearranges them to create new poems or other texts. The dichotomy of tonal and atonal impulses, compositional constructs that informed other of my compositions, form some structural basis for the work. Choice of these and other musical procedures is not arbitrary. They are not reasons in themselves, or meant to form a new mode of expression or imitate a particular musical style. Rather they support a dramatic narrative with deep resonances and historical allusion, one that draws the listener into the emotional substance of the difficult, often brutal dilemmas of war that humankind has wrestled and struggled with since before the printed word.

Full textAbstract:
Background. In South Africa violence related crimes are frequent, and interpersonal violence is one of the most common causes of injury and death. Violence can be related to social structures, poverty and income inequality. In South Africa 25% of the population live in extreme poverty, and 16% of households in Western Cape live in Informal dwellings. Drug and alcohol miss-use is a big problem. EMS personnel all over the world are exposed to violence. The last couple of years the rate of incidents of violence against the ambulances and EMS personnel in Western Cape and Cape Town has escalated, and a protocol to protect the personnel has been established. The protocol of Red Zones requires an armed escort for the ambulance and EMS personnel when working in certain areas. The red zones are often in low income areas, which makes United Nations’ Sustainable Development Goal of Reduced inequality relevant. The Purpose of this study is to describe how red zones affect patient waiting times and mission times for the ambulance in the Western Cape province of South Africa. Method. Quantitative analysis of priority 1 assignments in one month periods in 2016, 2017 and 2018 to Hanover Park, a suburb of Cape Town. Hanover Park has been considered a red zone since September 2016. Result. Seven different time periods in the missions were analyzed, comparing the City of Cape Town and Hanover park in 2016, 2017 and 2018. Conclusion. The result shows an increase in waiting times for EMS in Hanover Park, even though the precise response time could not be described. Call times and mission times for the entire City of Cape Town seem to have increased, indicating a problem beyond the red zones, potentially affecting everyone in need of an ambulance in the city. Further studies are encouraged.Bakgrund. I Sydafrika är våldsrelaterade brott vanligt förekommande, och interpersonellt våld är en av de vanligaste orsakerna till skada och död. Våldet kan relateras till sociala strukturer, fattigdom och inkomstskillnad. I Sydafrika lever 25% av befolkningen i extrem fattigdom och 16% av hushållen i Western Cape lever i informella bostäder. Missbruk av droger och alkohol är ett stort problem. Ambulanspersonal över hela världen utsätts för våld. De senaste åren har graden av våldshändelser mot ambulanser och dess personal i Western Cape och Kapstaden eskalerats och ett protokoll för att skydda personalen etablerats. Protokollet för Röda Zoner kräver en beväpnad eskort för ambulans och personal vid arbete i vissa områden. De röda zonerna är ofta i låginkomstområden, vilket gör FN: s hållbara utvecklingsmål för minskad ojämlikhet relevant. Syftet med denna studie är att beskriva hur röda zoner påverkar patienters väntetid och uppdragstider för ambulansen i Western Cape i Sydafrika. Metod. Kvantitativ analys av prio 1-uppdrag under en månadsperiod i 2016, 2017 och 2018 till Hanover Park, en förort till Kapstaden. Hanover Park har ansetts vara en röd zon sedan september 2016. Resultat. Sju olika tidsperioder i uppdragen analyserades, och jämfördes mellan hela Kapstaden och Hanover Park 2016, 2017 och 2018. Slutsats. Resultatet visar ökad väntetid för ambulansvård i Hanover Park, även om den exakta framkörningstiden inte kunde beskrivas. Uppdragstider för hela staden Cape Town verkar ha ökat, vilket indikerar ett problem bortom de röda zonerna, vilket potentiellt kan påverka alla som behöver en ambulans i staden. Ytterligare studier rekommenderas.

Full textAbstract:
Dans ce travail de thèse, nous proposons d'utiliser la technologie ULB pour établir un nouveau système de communication haut débit Radio Impulsionnelle (IR-ULB), basé sur un nouveau schéma de modulation nommé M-OAM (M-Orthogonal Amplitude Modulation) et les formes d'ondes orthogonales MGF (Modified Gegenbaeur Function). Ce système est dédié aux applications sans fil à courte portée, notamment les communications multimédia et le transport intelligent (ITS). Les modulations M-OAM proposées, sont évaluées sous le canal AWGN et les canaux ULB à trajets multiples à savoir IEEE.802.15.3a et IEEE.802.15.4a. Les résultats de simulation montrent que la performance du système proposé, en terme de taux d'erreur binaire (BER), est du même ordre que celle des modulations ULB traditionnelles. En outre, les modulations M-OAM offrent un très haut débit de données avec une faible complexité d'implémentation. En effet, la conception d'un tel système doit certes fournir un très haut débit mais aussi servir un grand nombre d'utilisateurs simultanément avec une bonne qualité de service. Dans cette optique, une nouvelle technique d'accès multiple DS-MGF-OAM est proposée. Ce système multi-utilisateur fait usage de la technique DS-ULB et l'orthogonalité des impulsions MGF pour permettre une communication efficace avec un nombre maximal d'utilisateurs. Néanmoins, l'effet de trajets multiples réduit la qualité de la transmission. Ainsi, la contribution de deux architectures de réception dans l'amélioration des performances est étudiée, à savoir le récepteur RAKE et l'égaliseur MMSE (Minimum Mean Square Error). Cette étude montre que le système de communication M-OAM offre de bonnes performances en terme de qualité de services (QoS). Après l'étape de simulation, les résultats expérimentaux des systèmes proposés dans les environnements réelles sont analysés et discutés. Dans la dernière partie de ce document, nous avons réalisé un prototype de traitement en temps réel sur une plateforme FPGA, offrant des temps de calcul à 3GHz grâce à des algorithmes parallélisables sur des architectures re-configurablesIn this thesis, we propose to use the UWB technology to establish a new communications system Impulse Radio (IR-UWB), based on a new modulation scheme called M-OAM (Orthogonal M-Amplitude Modulation) and orthogonal waveforms MGF (Modified Gegenbauer Function). This system is dedicated to the short-range wireless applications, especially multimedia communications and intelligent transportation (ITS). The proposed modulations M-OAM, are evaluated under the AWGN channel and UWB multipath channel namely IEEE.802.15.3a and IEEE.802.15.4a. Simulation results show that the performance of the proposed system in terms of bit error rate (BER) is the same as that of traditional UWB modulations. In addition, M-OAM modulations offer the highest data rate with low complexity of implementation. Indeed, the design of a such system should certainly provide a very high speed but also serve a large number of concurrent users with good quality of service. In this context, a new multiple access technique DS-MGF-OAM is proposed. This multi-user system makes use of the DS-UWB technology and orthogonal pulses MGF to enable effective communication with a maximum number of users. However, the multi-path effect reduces the quality of the transmission. Thus, the contribution of two receiver architectures in performance improvement is studied, namely the RAKE receiver and MMSE (Minimum Mean Square Error) equalizer. This study shows that the M-OAM communication system offers good performance in terms of quality of service (QoS). Following the simulation step, the experimental results of the proposed systems in real environments are analyzed and discussed. In the last part of this document, we performed a real-time protoptype on an FPGA platform, offering calculation time of 3GHz through parallelizable algorithms on reconfigurable architectures

Training a Support Vector Machine (SVM) requires the solution of a very large quadratic programming (QP) optimization problem. Sequential Minimal Optimization (SMO) is a decomposition-based algorithm which breaks this large QP problem into a series of smallest possible QP problems. However, it still costs O(n2) computation time. In our SVM implementation, we can do training with huge data sets in a distributed manner (by breaking the dataset into chunks, then using Message Passing Interface (MPI) to distribute each chunk to a different machine and processing SVM training within each chunk). In addition, we moved the kernel calculation part in SVM classification to a graphics processing unit (GPU) which has zero scheduling overhead to create concurrent threads. In this thesis, we will take advantage of this GPU architecture to improve the classification performance of SVM.

Due to the increasingly aging population in Taiwan, more and more social problems arose. Therefore, the Ministry of the Interior will publish the Reverse Mortgage Plan in 2012 to solve the problems. Under the premise that the greybeards could live in their houses throughout their lives, they could transform their ownership of houses into cash to cover their daily expenses. After that, the real estate could simultaneously bring the effect of living and financing into full play. First, we use the Taiwan Life Expectancy Database and simulate house prices and interest rates to estimate the constant annuity and the maximum loan to value. Second, we build the insurance pricing model of reverse mortgage, and then determining the best time required for the repossession of the collateral after loan termination and the most appropriate premium rates under the condition satisfying the present values of expected claim losses (PVEL) are equal to that of insurance premiums (PVMIP). Finally, the Reverse Mortgage Plan can be more complete by using the method above. We hope it will be useful for the development of reverse mortgage.

This research is based on the case study of the recheck decisions done in the 98th year of the ROC by the National Tax Administration of Central Taiwan Province. In this research, a full data model including the case features and recheckers’ characteristics mode is used separately, as well as to the profit-seeking enterprise income tax, business tax, individual income tax, estate tax and gift tax items in the sub sector model. This research uses logit model analysis to review the impact and analyze the important factors of the time period. The logit model uses a critical value of 0.5 for the classification to measure the recheck decisions and to analyze the time period’s predictive ability of the “within 60 days” and “over 60 days” classification. The main empirical results are analyzed as follows: 1.From the perspective of management, the Competent Tax Collection Authority should be cautious from the beginning. Using good quality management can reduce service failures and the subsequent need for service recoveries. It will avoid the waste of manpower and reduce the reduction of legal law suites. 2.Revenue officers shows a positive connection between the probability of requiring “over 60 days” when doing the recheck decisions at the 10﹪significance level. Showing that revenue officers, when doing recheck decisions, have a higher probability of requiring “ over 60 days”. In other words, revenue officers require a longer time period to do the recheck decisions than revenue assessors. It is suggested that it would be more beneficial if the Competent Tax Collection Authority promotes revenue assessors to perform the recheck decisions. 3.The Competent Tax Collection Authority should employ skilled workers, regardless of whether they are recheckers or revenue officers , if the workplace is closer to their homes, It is believed that it can improve the efficiency of their work. 4.The Competent Tax Collection Authority should regularly arrange training courses of professional skills in order to improve their member’s abilities as well as to help enhance and accelerate the trial speed of recheck cases.

Fire disasters occurred in the underground stations show that the potential life risk to the public do exist. In Chapter 2, several fire cases of underground stations of mass rapid transit system and railway system are introduced and discussed to conclude the affecting factors to life safety. Models or methods for calculating the Required Safe Egrees Time (RSET) and the Available Safe Egrees Time (ASET), Such as NFPA130 (Standard for Fixed Guideway Transit System), Architecture Research Center method in Japan, Department of Rapid Transit System (DORTS) in Taiwan are used to evaluate the life safety in the underground stations. Evacuation time is relatively complex, and it is an important index to the evaluation of building safety. In chapter 3, the evaluation of crowd evacuation for Taipei Railway Station is taken as an example to distinguish the applicability of Japan''s method which considers two major components of evacuation time：(1) the time taken up by relatively complex human behavior(usually referred as the pre-movement time) and (2) the time needed for the movement direct to the egress or escape(usually referred as the movement time) . By using this method, different evacuation times(T1、T2、Tf) are determined and compared with evaluation criterion. The conclusions are made with discussions of the results of this study and the observation practice. The case study chosen to be performed with EXDOUS software is Ching-Mei underground station in Shin-Dian line .The EXODUS software which comprises five core interacting component---the movement, behavior, occupant, hazard and toxicity submodels, is intended and designed to simulate the evacuation scenarios of Large number of individuals from an enclosure for the use in underground station, cinema theatres and lecture halls，etc. The computer software can depict both the input and output data in graphical way. Input parameters of sub-components in this study are based on field observations, code regulations and related theory of the underground station .The simulation results of Ching-Mei underground station of Shin-Dian line are compared with RSET and ASET of NFPA 130 which show the outcome is larger than the ASET regulated in NFPA 130.The main reasons of the results can be contributed to the non-uniform usage of the stairs and escalators which ends up in the disabilities to reach the optimal evacuation of initial design of egress system .The phenomenon of congestion of occupant is especially visible duing to the egrees facilities being deducted one escalator（here referred as door1 in this study） for the malfunction or maintenance reasons specified in NFPA130. Several solutions or tactics are proposed to improve the efficiency of egress facilities, including installation of stairs or escalators on the easily congested location, which is also the travel path of daily route. Besides that, proper actions taken by the underground staffs, such as effective evacuation guidance at the early stage to the occupant and early warning of fire occurrence via the public address system and fire alarm can also increase the efficiency of evacuation and greatly decrease the RSET.

Dissertação de Mestrado em Segurança aos Incêndios Urbanos apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra.A relevância da evacuação de edifícios em situação de incêndio para a proteção da vida humana, tem inerente, condições de emergência que são afetadas por fatores de difícil determinação que necessitam de ser definidos para o cálculo do tempo de evacuação e análise das condições de evacuação. O objetivo deste trabalho é o levantamento dos aspetos que influenciam o tempo de evacuação em edifícios que recebem público, desde o comportamento humano às caraterísticas físicas do edifício e às metodologias passíveis de adotar para a gestão da emergência, com vista a calcular o tempo necessário e disponível para a evacuação de um edifício e o tempo disponível para a evacuação através do programa de simulação FDS+EVAC. Para tal selecionou-se o edifício comercial Fórum Coimbra e realizaram-se oito simulações, quatro sem incêndio e quatro com incêndio, em cinco cenários distintos. Pela análise dos tempos de evacuação, com os condicionalismos referidos no projeto, estimou-se o tempo necessário para a evacuação do edifício de 17 minutos e 29 segundos, que oferece uma margem de segurança de 29,30% face ao tempo disponível para a evacuação e identificaram-se os pontos críticos de evacuação e oportunidades de melhoria quer para a gestão da emergência do edifício quer para futuros projetos. O desenvolvimento e verificação de metodologias facilitadoras da evacuação de edifícios e da segurança dos seus ocupantes constitui uma área de investigação da segurança contra incêndio com um grau de imprevisibilidade elevado mas o seu estudo continua a ser necessário, carecendo os resultados obtidos de especial cuidado no seu tratamento. O recurso a programas de simulação de incêndio e evacuação garante a definição de tempos médios de evacuação adequados, determinados quer pelos cenários de incêndio definidos pelo utilizador quer pela resposta humana expetável definida diretamente ou pelo programa de simulação ou pelo seu utilizador
In order to protect human lives, the importance of building evacuation under fire conditions has emergency conditions that are affected by factors which are hardly determined; however, they need to be defined for further calculation of evacuation time and analysis of the conditions of evacuation. The aim of this thesis is recording the aspects that influence the time of evacuation in buildings of public access. They go from human behavior to physical characteristics of the building as well as the most likely methodologies to adopt for the emergency management. All of this is used to calculate the available and required time for evacuation of a building and the available time for evacuation through the FDS+EVAC simulation program. Several simulations of Forum Coimbra were made in order to accomplish this goal, more precisely eight simulations, four with fire and four without fire. Considering all the conditions referred throughout the project and analyzing times of evacuation, the time needed for evacuation of the building is estimated to be 17 minutes and 29 seconds, which offers a safety margin of 29,30% relatively to the available time for evacuation. It was also possible to identify several critical points of evacuation and opportunities to improve the emergency management of the building as well as for future projects. The development and verification of the easiest methodologies of building evacuation and the safety of the people inside are one area of investigation to safety against fire on a high degree of unpredictability but its study is still needed, with its results needing a careful treatment. The use of fire and evacuation simulation programs guarantees an adequate definition of the average time of evacuation, determined by fire scenery customized by the user and the expected human answer defined directly by the program or its user.

Stainless steel screws and nails are used in the decoration, auto-mation and automobile industry mostly. However, the traditional pro-cess has to use the mold for metal end processing, which causes in-creasing costs and environmental pollution. Apply dieless drawing method to the stainless steel end geometry process would reduce envi-ronmental pollution and cost, due to the dieless drawing method has low material consumption and low environmental pollution. The rela-tionship between time-dependency temperature profile and metal end geometry was set up by laboratory previously. However, this temper-ature profile was calculated from by only set up the condition of drawing but not considerate the feasibility. This study approached the cooling energy on the node by the ap-proximate method and heat conduction model, for the purpose of real-ization and evaluation the feasibility of time-dependency temperature profile from above base. Construct the heating and cooling assemblies and realize the time-dependency temperature profile by amounts of cooling water obtained by calculation, reach the goal which forming metal end geometry. In addition, this study also attempts to calculate the feasibility of temperature profile by different temperature boundary and drawing speed, which obtain the limit of drawing speed and temperature boundary and discuss the relationship between energy and transient temperature distribution.

PURPOSE: The aim of this study is to better characterize the effect of the interval in time to the operating room on hospital length of stay and other post-surgical outcomes in adult patients with common emergency general surgery conditions who are admitted to the acute care surgical service at Boston Medical Center.
METHODS: This is retrospective cohort study examining a total of 321 subjects taken from an emergency general surgery registry at Boston Medical Center from May 2014 thru May 2015. Variables analyzed included: demographic factors, Charlson Comorbidity Index scores, times to the operating room, hospital length of stays, post- operative complications, and in-hospital mortality.
RESULTS: There were zero mortalities in this study and a 3.1% post-operative complication rate. There was a positive association between time to the operating room and hospital length of stay, even after controlling for covariates. It was found that those subjects who go to the operating room after 6 hours from the time of admission have an increased hospital length of stay by about 12 hours as compared to those subjects who do not.
CONCLUSIONS: In this study, subjects who went to the operating room sooner from the time of admission had associated shorter hospital length of stays and fewer post- operative complications.
