Full textSamtida befintliga konstruktioner blir äldre och de dimensionerade lasterna ökar med tiden.Ifatt med detta ändras även kraven för större laster. Därför bör regelbundna inspektioner ochförbättringar genomföras. I vissa områden kan det även förekomma seismiska rörelser som isin tur förorsakar skador på strukturer. Av bland annat dessa anledningar är det därför viktigtatt bedöma bärförmågan för befintliga konstruktioner. Syftet med arbetet är att granska demetoder och tillvägagångssätt som finns för att kunna bedöma den karaktäristiskatryckhållfastheten för betong i befintliga konstruktioner. Tryckhållfastheten är den styrandeparametern för materialet under tillståndsbedömningar. Huvudfokuset med arbetet är att bedöma den karaktäristiska tryckhållfastheten för befintligakonstruktioner som saknar information om nuvarande tryckhållfasthet. Till en början utfördesen noggrann litteraturstudie för alla applicerbara metoder. Därefter gjordes en undersökningoch bedömning av för- och nackdelar med vardera metod. Syftet med dessa metoder är attkunna mäta den nuvarande tryckhållfastheten för befintliga konstruktioner. Efter en ingående litteraturstudie, valdes de icke-destruktiva metoderna Ultrasonic pulsevelocity och Schmidt Hammer. Dessa metoder applicerades senare på Skuru bron i syfte attutföra icke-destruktiva tester för att bedöma betongens kvalitet. Tidigarekonstruktionshandlingar samt provtagningsrapporter från Skurubron som byggdes år 1914,har legat till grund för detta arbete. Företaget COWI är ansvariga för Skurubron projektet ochhar tillhandahållit all information om bron. Vidare, redovisar detta arbete olika beräkningssätt för samtliga metoder utifrån olikastandarder och tolkningsmetoder. För varje tolkningsmetod har evalueringar och analyserutförts med avseende på tillförlitlighet och praktisk tillämpning. De redovisadeberäkningssätten har använts för att räkna fram resultat från destruktiva och icke-destruktivatester. Resultaten tolkades i enlighet med europeiska koder, svenska koder och andratolkningsmetoder. Skillnaden mellan resultaten från samtliga tolkningsmetoder jämförs ochutvärderas med hänsyn till tillförlitlighet och effektivitet. Testresultaten från UPV och Schmidt Hammer bekräftade att betongen består av sammatryckhållfasthetsklass. Resultaten från de olika tolkningsmetoderna var dock olika.Anledningen till att det blev olika resultat beror på att varje tolkningsmetod utgörs av sinaegna metodiska procedurer. Resultaten visade även att vissa standarder kan övervärderaresultaten vilket kan resultera i fel bedömning av den karaktäristiska tryckhållfastheten. Åandra sidan, resulterade vissa tolkningsmetoder i lägre men säkrare uppskattning avtryckhållfastheten. Utöver detta, utfördes det beräkningar på de destruktiva testerna utifrån olikatolkningsmetoder. Beräkningarna baserades dels på att räkna på ett mindre antal kärnor.Skälet till detta är att man i praktiken vill undvika att borra ett stort antal kärnor. Resultatenvisade att korrekt bedömning och försiktighet vid val av metod och tolkningsmetod behöverimplementeras. Det rekommenderas även att överväga metoderna med hänsyn tillutredningens ändamål, dess begränsningar och antaganden.

Full textEsta tesis tiene el objetivo de ampliar y perfeccionar nuestra comprensión de por qué y cómo la dinámica de pareja afecta cuatro críticos resultados económicos que están directamente realacionados con la desigualdad y la estratificación. Estos resultados son, respectivamente; ser autónomo, la oferta de trabajo, el ahorro de los hogares y la distribución del ingreso. A lo largo de la tesis, con la dinámica de pareja, concibo dos conceptos: en primer lugar implica formar parte de una pareja (es decir, tener una esposa/o con ciertas características) versus ser soltero/a y transiciones entre estos dos estados. Y la segunda se refiere a los cambios en el comportamiento de los esposos debido a un cambio de contexto, como un aumento en el riesgo de disolución de la pareja. Por consiguiente, analiza las implicaciones de estos dos conceptos en cada una de estas variables económicas. La tesis se utiliza una serie de grandes conjuntos de datos longitudinales de diferentes países (p.e. PSID, GSOEP, PHCE, Living in Ireland Survey) y estratégias econométricas. Estas características incluyen el análisis de supervivencia, las estimaciones de diff-en-diff, simulaciones y descomposiciones.

CAPES
Este trabalho analisa propriedades da família de distribuições de probabilidade Composta N e propõe a sub-família Composta Poisson-Truncada como um meio de compor distribuições de probabilidade. Suas propriedades foram estudadas e uma nova distribuição foi investigada: a distribuição Composta Poisson-Truncada Normal. Esta distribuição possui três parâmetros e tem uma flexibilidade para modelar dados multimodais. Demonstramos que sua densidade é dada por uma mistura infinita de densidades normais em que os pesos são dados pela função de massa de probabilidade da Poisson-Truncada. Dentre as propriedades exploradas desta distribuição estão a função característica e expressões para o cálculo dos momentos. Foram analisados três métodos de estimação para os parâmetros da distribuição Composta Poisson-Truncada Normal, sendo eles, o método dos momentos, o da função característica empírica (FCE) e o método de máxima verossimilhança (MV) via algoritmo EM. Simulações comparando estes três métodos foram realizadas e, por fim, para ilustrar o potencial da distribuição proposta, resultados numéricos com modelagem de dados reais são apresentados.
This work analyzes properties of the Compound N family of probability distributions and proposes the sub-family Compound Poisson-Truncated as a means of composing probability distributions. Its properties were studied and a new distribution was investigated: the Compound Poisson-Truncated Normal distribution. This distribution has three parameters and has the flexibility to model multimodal data. We demonstrated that its density is given by an infinite mixture of normal densities where in the weights are given by the Poisson-Truncated probability mass function. Among the explored properties of this distribution are the characteristic function end expressions for the calculation of moments. Three estimation methods were analyzed for the parameters of the Compound Poisson-Truncated Normal distribution, namely, the method of moments, the empirical characteristic function (ECF) and the method of maximum likelihood (ML) by EM algorithm. Simulations comparing these three methods were performed and, finally, to illustrate the potential of the proposed distribution numerical results with real data modeling are presented.

Full textThis thesis aims to specify an assistance system based on the cooperation of the distributed robotic devices in the environment. It is characterized by adaptation to users' needs according to their physical abilities, their profile and their situation. It also relies on the collaboration between the assistive devices and the environment. We proposed a generic architecture to specify an ambient assistance system that can be deployed in the public spaces. In addition, we have proposed the methods of adjustment and adaptation of the robotic assistive devices. These methods are based on the remote sensing and automatic estimation. The experimental tests performed in this thesis are focused on the ambulation aid system for people with reduced mobility. Two studies with persons with reduced mobility have validated this work: the remote identification of physical characteristics of users, real time estimation of user's capacity of ambulation through the interaction with the walker

Full textTraditional large space structure construction incorporates the use of lightweight tubular metal alloys that have good strength to weight and stiffness to weight ratio. Recently, however, space structure construction has shifted focus on materials that are ultra lightweight, have high strength, have low package volume and possess excellent damping characteristics. Substantial damping is required in space since there is no surrounding medium to provide damping. Such a construction uses composites in a fabric form that displays viscoelastic behavior. The viscoelastic behavior is attributed to energy dissipation because of the shear stresses between the various fibrous strands that are kept in place by constraining viscoelastic layers. This type of vibration control falls under the rubric of passive damping of structures and has been found to have certain advantages over active damping such as less complexity as it does not require sensors, actuators and power supply that are needed for active damping.
One such material consists of woven carbon strands constrained by layers of viscoelastic damping material. Dynamics and buckling behavior of a structure in the form of a tube made from this material with metallic end caps is modeled and analyzed using commercially available Finite Element Analysis code ABAQUS®. The current analysis deals with the non-pressurized tube since the structure can maintain the tubular configuration as well as support end caps on account of the stiffness provided by the composites. Since no simple analytical approaches are available to predict damping of these materials, experimental data was used to estimate the damping characteristics of the material. The mass of the end cap was also estimated from the experimental impulse response as exact mass of the end cap (that was rigidly fixed to the tube) was unknown.

First, we present a theoretical framework of spatial and spatio-temporal point processes. The rest of the thesis is organized as follows. In Chapter 2 we present a new family of optimal and positive kernels an alternative unbiased estimator for the product density function. Its performance is compare under several kernel through MISE. In Chapter 3 a new kernel estimator of spatio-temporal product density function are given and also are developed close expressions for the variance under the Poisson case. En el capítulo 4 nos centramos en los métodos de orientación de segundo orden que proporcionan una herramienta natural para el análisis de los datos de proceso Punto espaciales anisótropas. Finally, we provide a general description of the currently ongoing research projects which have emerged motivated by the close relationship with the second-order properties.

Full textSex estimation is one of the primary aspects of identification, since it restricts a large part of the suspect population. Several studies have used odontometric parameters for sex estimation and the canine is the tooth that has presented greater sexual dimorphism in the human dentition, however, these parameters are populationspecific. The aim of this study was to define the values of the mandibular canine index (MCI) and MCI Standard proposed by Rao et al. (1989) in a Brazilian Southeast population and their respective accuracy in the sex estimation as well as its validation through the multivariate classification analysis. In a sample of 45 men and 45 women aged 18 to 35 years, the measurements of the mesio-distal distance of the right lower canine (MD43) and the inferior intercanine distance (DIC) were collected directly in the mouth with the aid of a digital caliper by three different examiners. MCI was 0.255 and 0.248 respectively, for the male and female, MCI Standard of 0.240, with an average accuracy of 52.22%. This result could indicate that the measures used do not present significant sexual dimorphism or only the ineffectiveness of the methodology in this population. For confirmation, the multivariate classification analysis was applied, which pointed out the correlation between the measurements MD43, DIC and sex, with an average accuracy of about 75 to 80%, confirming the sexual dimorphism in these parameters. Therefore, it was concluded that the measures that make MCI are good for sex prediction, however, MCI formulas are not effective in the study population

Perimeter of the basin, the ratio of the basin perimeter to the main stream length of the same basin, the drainage frequency, the mean slope of basin, v the mean annual precipitation and the curve number are the parameters that have been analysed for the multilinear statistical model. Principal Component Analysis, Multiple Regression Analysis and Stepwise Regression Analysis have been run for the data sets. For the computed discharges validation has been done. As a result of validation, it has been seen that the stepwise regression gives much closer discharge values to the observed values than the multiple regression results.

Full textRecent advances in composite structures and active control systems have made the concept of a forward swept wing aircraft a viable alternative to the more conventional configurations. This thesis encompasses some of the work resulting from a three year research program covering the dynamic behaviour and characteristics of a FSW aircraft having a closely coupled canard. The dynamic model has been based on the output of a first order optimisation routine with emphasis on minimum induced drag and static margin as the two most important criteria. Stability characteristics of the dynamic model were extracted from the transient response tests in both longitudinal and lateral modes by means of a statistical method, namely Extended Kalman Filter (E. K. F. ). In carrying out the dynamic tests, use was made of the facilies outlined by Ref. 8. Validated through computer based experiments, the Extended Kalman Filter algorithm has successfully been applied to the open-loop wind tunnel tests. Simulations of the equations of motion using estimates of stability derivatives obtained in this way closely match the observed behaviour. Furthermore, substitution of aerodynamic data obtained via static wind tunnel measurements in theoretically derived expressions for some of the stability derivatives has resulted in an alternative set of stability derivative estimates. ' Finally, estimates of the stability derivatives obtained with the E. K. F., first order optimisation program and static tests are compared. Although the results are limited to very low subsonic Mach numbers, nevertheless, they are very encouraging. It is hoped that future work might extend the studies into unstable flight regimes.

The data were obtained from a 1988 file established by the Defense Manpower Data Center containing locational and biodemographic information on 238,174 enlisted reservists. A random sample of 91 reserve centers was selected for the analysis. The logistic and normal distributions were evaluated as possible candidates for fitting the commuting distance distribution. It was found that a power transformation of the fractional distance traveled fit both distributions quite well. Parameters for the two distributions are obtained through a method of maximum likelihood estimation. Finally, a multiple regression equation is used to estimate the parameters of the commute distance distribution as a function of reserve center and market characteristics.

Full textThis paper presents estimated aeronautical telemetry channel characteristics during bit error events. A T-39 aircraft was flown around various test corridors while transmitting a filtered 10 Mb/s pseudo-noise (PN) sequence binary phase shift keying (BPSK) signal. The received signal was down converted to 70 MHz, digitized when trigger criteria were met, and stored for later analysis. Received signal strength was also recorded. The first step in data analysis consisted of dividing the fast Fourier transform (FFT) of the recorded signal by the FFT of the expected signal. The received signal strength data was then used to correct for flat fade effects. The resulting signal is the difference (dB) between the expected signal at the receiver intermediate frequency (IF) output and the measured receiver IF output during the error event. This difference is the aeronautical telemetry channel characteristic. The characteristics of this difference signal were then matched against a 2-ray and 3-ray multipath fading model with reflected signal amplitude and path delay as the variables.

The definition of characteristic value has two different parts. First of all, the value affecting the occurrence of the limit state and cautious estimate. In this research, cautious estimate is the core issue. Moreover, the geotechinical parameter which conform in affecting the occurrence of the limit state is called mobilized value. Eurocode 7 hopes the estimate of mobilized value supposed to locate in confidence level of 95%. This cautious estimate is about 5% fractile. However, there are two possible interpretations for the 5% quantile for the characteristic value in Eurocode 7. The first interpretation is that the 5% quantile is on the input geotechnical parameters. The second interpretation is that the 5% quantile is on the output limit state G. The major issue of this research explains the two ideas above which is the closest to Eurocod 7’s purpose. According to Eurocode 7’s purpose, the probability value of estimate should be controlled in 5% which is lower than genuine in-situ strength parameter. By going through first and second interpretation, structure deisgn would be simulated. Figuring out the probabilty of structur failure, First interpretation is found that probaility of failure has highly variable and the failure probability is very small. However, second interpretation does not has those problems. However, second interpretation requires the CDF of the limit state G and the ability to control this CDF. The two requirements are very unrealistic for engineer. This research hope to propose an approximate fulfilling second interpretation.
