A biofidelic finite element model was developed from an acquired set of CT scans for a range of human head and UAS impacts to provide simulations of multiple velocity scenarios of impact severity at four impact orientations on the human head. The hypothesis was that a correlation existed between the total amounts of kinetic energy of the impact from the UAS and human head collision, as well as that location of impact plays a role in the injury risk sustained. Linear acceleration, angular velocity, and pressure data values were calculated for each individual simulated case and then further correlated to injury risks that represent the severity of damage that would be sustained from the collision. Resulting data proved to show that impact kinetic energy, impact orientation, and impact response of the head and UAS all play vital roles in the amount of damage that is sustained from the impact collisions.

[pt] Este estudo apresenta critérios para avaliação de condomínios logísticos sob pontos de vista social, ambiental, econômico e técnico-operacional. Para cada um destes critérios são apresentados os diferentes aspectos que os compõem e são sugeridos fatores de ponderação para estimativa do grau de viabilidade de implantação de condomínios logísticos em cidades situadas no entorno de grandes centros urbanos. Em particular, foi considerada a hipótese de implantação de condomínios logísticos na região metropolitana da cidade do Rio de Janeiro, e que se beneficiam em função de atração de demanda pelo porto do Rio. São definidos e classificados os tipos de condomínios e também apresentadas sínteses das estratégias internacionais de implantação de plataformas logísticas. Os critérios propostos para as avaliações estabelecem, para cada condomínio, um grau de viabilidade que pode variar de 0 a 100 por cento, e a aplicação desses critérios permitiu selecionar algumas localizações que obtiveram grau de viabilidade superior a 75 por cento, sendo que valores mais elevados sugerem recomendações de uso. Destacando-se um condomínio já existente no bairro da Pavuna, na cidade do Rio de Janeiro, que atingiu a marca de 92 por cento. / [en] This study presents a discussion of criteria for evaluation in the metropolitan region of the city of Rio de Janeiro and its impacts in order to be reviewed in terms of construction as well as its financial and operational performance. As a way to study, were looked for reference topics and also real enterprises options to compare indicators for development, definition and propose conditions for good performance in this area and scope. Logistics condos can be defined as storage areas in a consolidated or segregated way, using areas that can be shared with companies or used alone to meet demand or provide gains through their use. These centers were developed to provide economies for logistics operators, carriers, industries and retailers, meeting their needs for warehousing, distribution, cargo consolidation and vehicles distribution. By bringing together several sheds with flexibility to segregate spaces in a unique place with security and shared services infrastructure, where companies enjoy a cost-benefit relationship that they would not be able to achieve alone. In addition, it aims to offer services and provide logistical integration, cost reduction in inventories, facilities and processes, as mentioned by DIAS (2013). Logistics condos are also considered as evolution of the Distribution Centers (CDs) and are made up of different complexes of warehouses with different sizes and modules, located in condominiums, where costs, infrastructure are shared, as well as expenses with surveillance and security (Sobreira, 2012). According to DUBKE (2006), a logistics platform is a name given to logistics centers that operate by adding value to the product through a wide variety of services. Another mention is the Integrated Logistics Center (ILC) concept, which brings together a number of functions of transportation, logistics, operational support, and industrial processing. Such ILCs may house intermodal road and rail terminals and logistics platforms capable of carrying out for example stocking, distribution and consolidation operations. Through this concept, it can be concluded that logistics condominiums can be part of logistics platforms as a whole, mainly because they are sheds for the storage part as mentioned.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Multiple antennas promise high data capacity for wireless communications. Most space-time coding schemes in literature focus on the rich scatter environment. In this paper, we argue that minimax criterion is a good design criterion for space-time codes over the avionic telemetry channels. This design criterion is different than those of space-time codes over rich scattering Rayleigh fading channels. Theoretical and numerical results show that the codes with optimal performance in Rayleigh fading channels do not necessarily have optimal performance in avionic telemetry channels. Therefore, the space-time codes should be carefully designed/selected when used in the avionic telemetry channels.

The current study employed a Monte Carlo design to examine whether samplebased and formula-based estimates of cross-validated R2 differ in accuracy when predictor selection is and is not performed. Analyses were conducted on three datasets with 5, 10, or 15 predictors and different predictor-criterion relationships. Results demonstrated that, in most cases, a formula-based estimate of the cross-validated R2 was as accurate as a sample-based estimate. The one exception was the five predictor case wherein the formula-based estimate exhibited substantially greater bias than the estimate from a sample-based cross validation study. Thus, formula-based estimates, which have an enormous practical advantage over a two sample cross validation study, can be used in most cases without fear of greater error.

The purpose of this study was to empirically examine two empirically examine two main areas of concern in selecting criteria for validation studies: the development of the criterion and the multiple criteria versus composite criterion debate. Evidence was found for the ability of the various weighting schemes used to generate composites that were statistically and conceptually different from one another. Knowledge of the nature of each composite, along with the multiple criteria approach, proved essential to understanding the composite criterion to the validation process. Selection and treatment of the criterion apparently consist of judgment and individual estimations.

Esta dissertação investiga, por meio de uma leitura imanente da filosofia de Nietzsche, a relação problemática entre perspectivismo e relativismo em sua obra. Inscrito na efetividade, concebida como vontades de potência que se exercem de modo perspectivístico e interpretante, o perspectivismo propõe a ideia de que não existem fatos, mas apenas interpretações perspectivísticas. Cumpre então perguntar se tal perspectivismo incorreria num relativismo radical, segundo o qual todas as interpretações seriam equivalentes. Procuraremos mostrar que não é possível responder a esse problema de modo unilateral, com um simples e taxativo sim ou não. Por um lado, o exame de seus escritos indica que Nietzsche não pretenderia assumir a posição de um relativista radical na medida em que hierarquiza as interpretações e reivindica a superioridade de sua própria interpretação de mundo. Mais do que isso, sua filosofia aponta até mesmo para a inviabilização daquele relativismo: ao associar os conceitos de perspectiva e interpretação ao de valor, indica que toda perspectiva e toda interpretação avaliam e hierarquizam, de modo que inexistiriam perspectivas e interpretações que efetivamente considerassem as demais como dotadas de mesmo valor. Por outro lado, se admitida a concepção de uma efetividade perspectivística e interpretativa, então todo e qualquer critério estabelecido para hierarquizar as interpretações teria de ser relativo a uma perspectiva e a uma interpretação determinadas, não consistindo num critério incondicionado e objetivo. Assim, uma vez considerada a relatividade de todo critério, ressurge o problema do relativismo. / This dissertation researches, through an immanent reading of Nietzsches philosophy, the problematic relationship between perspectivism and relativism in his work. Intrinsic in the reality, conceived as wills to power that express themselves in a perspectivist and interpretive way, the perspectivism argues that there are no facts, but only perspectivist interpretations. So it is necessary to ask whether such a perspectivism incur a radical relativism, according to which all interpretations would be equivalent. We shall try to show that it is not possible to answer this problem unilaterally, with a simple yes or no. On the one hand, the examination of his writings indicates that Nietzsche would not intend to take the position of a radical relativist, for he ranks the interpretations and claims the superiority of his own interpretation of the world. More than that, his philosophy would point to the impossibility of that relativism: since Nietzsche associates the concepts of perspective and interpretation with the concept of value, he indicates that every perspective and every interpretation evaluate and rank, so that there would not be perspectives and interpretations that effectively could consider the others as equivalent. On the other hand, if we accept the conception of a perspectivist and interpretive reality, so any criterion fixed in order to rank the interpretations would depend on a certain perspective and interpretation, and thus it would not be an unconditional and objective one. Hence, since we consider that any criterion is relative, the problem concerning relativism resurfaces.

"In the prediction of phenomenon behavior there is a presupposition that a similarity exists between model and phenomenon. Success of application is derived from that similarity. An example of this approach is the use of similarity conditions such as Reynolds number in flow problems or Fourier number in heat transfer problems. The advent of performance-based codes has opened up opportunities for many diverse avenues of fire model implementation. The reliability of models depends upon model correspondence uncertainty. Model correspondence uncertainty is incomplete and distorted information introduced into a simulation by a modeling scheme. It manifests itself as 1) the uncertainty associated with the mathematical relationships hypothesized for a particular model, and 2) the uncertainty of the predictions obtained from the model. Improving model implementation by providing a method for rank-ordering models is the goal of the Model Validity Criterion (MVC) method. MVC values can be useful as a tool to objectively and quantitatively choose a model for an application or as part of a model improvement program. The MVC method calculates the amount of model correspondence uncertainty introduced by a modeling scheme. Model choice is based upon the strategy of minimizing correspondence uncertainty and therefore provides the model that best corresponds to the phenomenon. The MVC value for a model is quantified as the sum of the length of two files. These files are individual measures of model structure correspondence uncertainty and model behavior correspondence uncertainty. The combination of the two uncertainty components gives an objective and structured evaluation of the relative validity of each model from a set of likely candidate models. The model with the smallest uncertainty files has the lowest MVC value and is the model with the most validity. Ultimately the value of such a method is only realized from its utility. Example applications of the MVC method are demonstrated. Examples evaluate the rank-ordering of plume physics options used within the computer zone model WPI-Fire when validated against upper layer temperature data from compartment-fire test scenarios. The results show how candidate models of a set may be discriminated against based on validity. These results are powerful in that they allow the user to establish a quantitative measure for level of model performance and/or choose the most valid model for an application."

Dado um espaço vetorial topológico $X$ e um operador linear $T$ contínuo em $X$, dizemos que $T$ é {\\it hipercíclico} se, para algum $y \\in X$, o conjunto $\\{y, T(y), T^2(y), T^3(y), \\ldots T^n(y) \\ldots \\}$ for denso em $X$. Um dos principais resultados envolvendo operadores hipercíclicos consiste no chamado {\\it Critério de Hiperciclicidade}. Tal Critério fornece uma condição suficiente para que um operador linear contínuo seja hipercíclico. Por muitos anos, procurou-se saber se o Critério também era uma condição necessária.

Given a set of potential explanatory variables, one model selection approach is to select the best model, according to some criterion, from among the collection of models defined by all possible subsets of the explanatory variables. A popular procedure that has been used in this setting is to select the model that results in the smallest value of the Akaike information criterion (AIC). One drawback in using the AIC is that it can lead to the frequent selection of overspecified models. This can be problematic if the researcher wishes to assert, with some level of certainty, the necessity of any given variable that has been selected. This thesis develops a model selection procedure that allows the researcher to nominate, a priori, the probability at which overspecified models will be selected from among all possible subsets. The procedure seeks to determine if the inclusion of each candidate variable results in a sufficiently improved fitting term, and hence is referred to as the SIFT procedure. In order to determine whether there is sufficient evidence to retain a candidate variable or not, a set of threshold values are computed. Two procedures are proposed: a naive method based on a set of restrictive assumptions; and an empirical permutation-based method. Graphical tools have also been developed to be used in conjunction with the SIFT procedure. The graphical representation of the SIFT procedure clarifies the process being undertaken. Using these tools can also assist researchers in developing a deeper understanding of the data they are analyzing. The naive and empirical SIFT methods are investigated by way of simulation under a range of conditions within the standard linear model framework. The performance of the SIFT methodology is compared with model selection by minimum AIC; minimum Bayesian Information Criterion (BIC); and backward elimination based on p-values. The SIFT procedure is found to behave as designed—asymptotically selecting those variables that characterize the underlying data generating mechanism, while limiting the selection of false or spurious variables to the desired level. The SIFT methodology offers researchers a promising new approach to model selection, whereby they are now able to control the probability of selecting an overspecified model to a level that best suits their needs.
