It was shown in Spong [1999b] that the passive gaits for a planar 2DOF biped walking on a shallow slope (Goswami et al. [1995]) can be made slope invariant by a passivity based control that compensates only the gravitational torques acting on the biped. In this paper we extend these results to the general case of a 3-D, n-DOF robot. We show that if there exists a passive walking gait, i.e., if there exists a ground slope and a set of initial conditions that give rise to a stable limit cycle trajectory of the system, then there exists a passivity-based nonlinear control law that renders the limit cycle slope invariant. The result is constructive in the sense that we generate the resulting control law and initial conditions from the initial conditions of the passive biped and the ground slope. This intuitively simple result relies on some well-known symmetries in the dynamics of mechanical systems with respect to the group action of SO(3) on solution trajectories of the system. We also discuss the use of passivity-based control to increase the basin of attraction of the passive limit cycle.
Abstract—a Long-term Human-robot Proxemic (hrp) Study Was Performed Using a Newly Developed Autonomous Proxemic System (aps) for a Robot to Measure and Control The

approach distances to the human participants. The main findings were that most HRP adaptation occurred in the first two interaction sessions, and for the remaining four weeks, approach distance preferences remained relatively steady, apart from some short periods of increased distances for some participants. There were indications that these were associated with episodes where the robot malfunctioned, so this raises the possibility of users trust in the robot affecting HRP distance. The study also found that approach distances for humans approaching the robot and the robot approaching the human were comparable, though there were indications that humans preferred to approach the robot more closely than they allowed the robot to approach them in a physically restricted area. Two participants left the study prematurely, stating they were bored with the repetitive experimental procedures. This highlights issues related to the often incompatible demands of keeping experimental controlled conditions vs. having realistic, engaging and varied HRI trial scenarios.
Beng 260-neurodynamics Final Report

The project aims to explore two fractal models (by Lowen and Liebovitch) of ion channel kinetics, and how this affects spike train patterns. The project also intends to extend the Liebovitch model and explore how fractal dimension affects potassium ion channel conductance profiles, and the behavior and rate of action potentials. 1 I n t r o d u c t i o n Fractal patterns have been used to model many different aspects of our natural world, from coastlines, to mountains, to neuromorphology, all of which deal with fractal behavior as applied to geometry. Fractal behavior can also be imparted to dynamical systems, particularly neural spike train patterns. Experimental evidence has indicated that neurons along the auditory pathway, demonstrate a fractal firing pattern, where the term fractal is used to signify that the fluctuations of spiking rate appear self similar over various integration time periods, as shown in Figure 1 [9]. Figure 1: a) A fractal fluctuation rate. Fluctuations don’t change in amplitude, even as the rate is taken over longer time periods. b) Non-fractal fluctuation rate. Fluctuations decline in amplitude and smooth out as the firing rate is taken over longer time periods. In considering possible biophysical origins of this fractal behavior of auditory nerve spiking trains, one possibility that has been suggested relates to fractal kinetics of neuronal ion channels.

CAMBIO EN LAS PROPIEDADES FÍSICAS DE UN ULTIC HAPLOXERALF CULTIVADO CON VID (VITIS VINIFERA)

INTRODUCCIÓN. La actividad agropecuaria modifica la estructura del suelo; la magnitud del cambio depende del tipo de manejo y del tiempo de utilización desde la incorporación del suelo a la actividad silvoagropecuaria, luego de la eliminación de la vegetación nativa (8, 11). Al cambiar el uso del suelo de bosque nativo a plantaciones de pino (Pinus ponderosa Dougl.), se ha observado una pérdida del grado estructural de agregados granulares; ello reflejaría un cambio de la distribución de poros por tamaño, al aumentar la microporosidad y disminuir la macroporosidad bajo pino (5, 9). En Sudán (14) también se han utilizado sitios cercanos de vegetación nativa (pradera de Cynodon dactylon L., Ocinum basilicum L.) para comparar algunas propiedades del suelo (nitrógeno total, carbono orgánico y densidad aparente) con sitios de cultivo convencional de caña de azúcar de más de 40 años, y de menos de 10 años desde su establecimiento. Otros autores (7) han utilizado la condición de vegetación nativa, para observar cambios en el contenido de carbono debido a cambios en el uso del suelo, comparándolo con sitios de rotación con labranza convencional (soya-trigo-maíz). Todas las experiencias concluyen que al existir un cambio de uso del suelo existe una disminución de carbono orgánico (14) y un cambio en la dinámica de la formación de agregados, disminuyendo en el suelo la estabilidad de los agregados al agua y aumentando los riesgos de erosión (7, 10). Falta estudiar con mayor detalle el efecto de la labranza continua en sistemas de cultivos persistentes. El presente estudio busca determinar cómo el cultivo de la vid afecta algunas propiedades físicas del suelo, y ver en qué magnitudes se manifiestan los cambios en las variables a medir, tanto en la entre hilera como en la sobre hilera, tomando como referencia el suelo bajo vegetación natural.
TRENDS IN MODERN SYSTEM THEORY

The topics considered are related to linear control system design, adaptive control, failure detection, control under failure, system reliability, and large-scale systems and decentralized control. It is pointed out that the design of a linear feedback control system which regulates a process about a desirable set point or steady-state condition in the presence of disturbances is a very important problem. The linearized dynamics of the process are used for design purposes. The typical linear-quadratic design involving the solution of the optimal control problem of a linear time-invariant system with respect to a quadratic performance criterion is considered along with gain reduction theorems and the multivariable phase margin theorem. The stumbling block in many adaptive design methodologies is associated with the amount of real time computation which is necessary. Attention is also given to the desperate need to develop good theories for large-scale systems, the beginning of a microprocessor revolution, the translation of the Wiener-Hopf theory into the time domain, and advances made in dynamic team theory, dynamic stochastic games, and finite memory stochastic control.
How Significant Is Culture in the Development of Coping Styles among Latinas

The purpose of this study was to investigate the relationship between the cultural worldview perspective and coping styles of Puerto Rican females in the study. According to Hobfoll's "Conservation of Resources Theory," people strive to retain, protect, and build resources. Hobfoll's theory addresses some of the issues associated with the stress of living in different cultures concurrently. Latinas living in the continental United States are faced with choosing the optimum coping behaviors that will preserve their energies (resources) dealing with the socialization agents (mass media, printed language, education system, church, and governmental entities) of the host society. The thrust of the study approached the research from the perspective of the individual coping on a daily basis with an available repertoire of behaviors, having been transmitted through the various social models or significant others. Jackson's Cultural World View Inventory and Hobfoll's Strategic Adaptation Coping Sub Scales were the inventories of choice for this study. (Contains 37 references.)

420. ON A EQUID FOSSIL FROM HIRAMAKI FORMATION

In April. 1958. R. HIDA, a farmer in Hi ramaki, Kani city. Gifu Prefecture found a lower jaw of Inehitherium on a valley wall of Ohata in Hiramaki, and possessed it as a part of dragon remains. The junior writer, while making a field survey of this arca, acquired i his information and could borrow the specimen from IIIDA for this study. From Omori, 1km southeast of this locality, two fragmental teeth of Anchitherum were found and described by H. MATSUMOTO in 1921. The specimen described here is of the same species as MATSUMOTO'S and is in far better preservation. The formation of the neighbourhood of the locality consists of alternation of white tuffaceous sandstone and black siltstnne and belongs to the uppermost part of Lower Hiramaki formation. MATSUNIOTO described Palaeotapirus yagii MAT. , Chilotherium pugnator (MAT.), Amphitragulus minoensis MAT. Gomphotherium annectens (MAT.), sciurid sp. besides this species. He correlated the fauna of Hiramaki formation with that of European Burdigalian or Gaj-Lower Siwalik of India. In 1919 F. TAKAI reported Palaaatapirus yogii and Chilalberium pugnalor from Katabira, Kani city and regarded the age of Hiramaki fauna as middle to late Miocene. It may be significant that the species in question is very much like A. gobiense COLBERT from Tungur formation of Outer Mongolia. Considered from this point of view, the uppermost. part of Lower Hiramaki formation may be treated as kite Miocene in age. H ere the writers extend their hearty thanks to Prof. F. TAKAI, Dr. T. HANAI, Mr. Y. HASEGAWA for their valuable advice and help during the course of this research and to Mr. R. HIDA for his kindness to permit them to use this specimen for their study.
Bundles of generalized theta functions over abelian surfaces

We study the bundles of generalized theta functions constructed from moduli spaces of sheaves over abelian surfaces. The splitting type of these bundles is conjecturally expressed in terms of a new class of semihomogeneous bundles. The conjecture is confirmed in degree zero. Fourier-Mukai symmetries of the Verlinde bundles are found, consistently with strange duality. A version of level 1 strange duality is established.
INTERFERENCE AND FADE MITIGATION TECHNIQUES FOR KA AND Q/V BAND SATELLITE COMMUNICATION SYSTEMS

Up to the past few months, geostationary telecommunication satellite systems have kept taking advantage of the satellite natural wide area coverage capability, of their rather rapid deployment and efficient capability to provide a telecommunication infrastructure in areas where the terrestrial ones were deficient or did not exist. In a context where “broadband” was the major, if not the only driving factor for the development of telecommunication infrastructures, satellites have imposed themselves as natural carriers for broadcast services while remaining an alternative carrier for point-to-point oriented services. But the situation has changed, and the mid to long term perspectives for geostationary satellites are challenged by their capability to remain competitive, in terms of capacity versus cost and supported services, with regards to the evolution of existing terrestrial technology and the emergence of new ones. For the satellite to keep playing a major role as a carrier for broadcast/multicast services while offering a competitive complementary telecommunication means for the provision of point to point oriented services, it should offer wide capacity, good availability, high flexibility, and guarantee the required quality of service in a cost efficient way.

Expert opinion is often sought with regard to unknowns in a decision-making setting. Our presumption is that such opinion is elicited as an incomplete probabilistic specification either in the form of probability assignments to fixed intervals or in the form of selected quantiles. We present likelihoods for such specification which arise through random mixtures of Beta distributions. We presume that a supra Bayesian presides over the opinion collection resulting in the posterior distribution as the mechanism for pooling opinion. The models are applied to opinion collected regarding points per game for participants in the 1991 NBA championship basketball series.

Individual representations belong to the individual experience, are perceptions, sensations, images in the consciousness of each person and why were unstable and ephemeral. Already collective representations were impersonal, objective, stable in transmission and reproduction, so resistant to change. If it changed, it was not because it was the normal change, but because it had imperfections. Curiosity moved to the preparation of this study arose from the need to understand the social representations – RS, raised through the discourse of maceioense population, on the promotion of physical activity in your city. Responses, mostly propose more government action. Some obstacles are listed by the study group that tend to increase due to lack of: security, physical infrastructure and qualified professional. It is crucial to know the circulating discourses so that together the relevant bodies, can intervene effectively and fosters public policies oriented physical activity in the city.
Testen und Schätzen individueller Behandlungseffekte bei hochdimensionalen Kandidaten-Biomarkern

Hintergrund: In der personalisierten Medizin verfolgt man den Ansatz, dass nicht jede Behandlung für alle Patienten gleich wirkt. Eine statistische Methode zur individuellen Behandlungswahl, stellt die Entwicklung von prädiktiven Biomarkern dar. Methoden: In dieser Arbeit wird eine Methode von Matsui et al. (2012) mit einem neuen Ansatz zur Entwicklung von hochdimensionalen Biomarkern anhand von omics-Daten verglichen. Der neue Ansatz stellt im Gegensatz zu der Methode von Matsui et al. (2012) eine multiple Herangehensweise mittels Lasso-Schätzer dar. Dabei wird sowohl ein einschrittiges als auch zweischrittige Verfahren betrachtet. Um den Treatmenteffekt zu testen werden Permutationstests vorgestellt. Wobei die Verfahren unterschiedliche Hypothesen betrachten. Ergebnisse: Eine Simulationsstudie zeigt, dass die Vorhersagegenauigkeit durch den multiplen Ansatz verbessert werden kann. Der neue Ansatz erkennt mehr der wahren Effekte und lässt den fälschlicherweise geschätzten Effekten nicht so viel Einfluss zukommen wie die Methode von Matsui et al. (2012). Dabei hängen die Ergebnisse aller Methoden stark von den vorhandenen Effekten in den Daten ab.

Sujeito nulo na aquisição: um parâmetro em mudança – sujeito preenchido na aprendizagem: a eterna tentativa de mudança

Se considerarmos que as linguas naturais sao um “dote” do ser humano e apenas dele e que todos os seres humanos possuem um mesmo “dote” linguistico, poderiamos supor que todas as linguas sao iguais. Entretanto, sabemos que essa suposicao nao e verdadeira. Ha diferencas entre as linguas naturais de todo o mundo que nao se restringem apenas a diferencas lexicais, foneticas ou fonologicas, mas tambem, a diferencas na organizacao das palavras nas sentencas, na sintaxe. Como, entao, explicar esse aparente paradoxo: todos os seres humanos possuem um mesmo aparato linguistico (concepcao inatista da aquisicao da linguagem) e, ao mesmo tempo, determinados grupos se utilizam de codigos linguisticos e de estruturas sintaticas diferentes para sua comunicacao e interacao?

São Carlos, 2002, I 85 p., Dissertação (Mestrado)Escola de Engenharia de São Carlos, Universidade de São Paulo. The use of mathematical models in groundwater problems allows to estimate severa I ways o f this resource management. This subject is useful, mainly facing a situation where new wells must be drilled. Thus, sectors for public water supply needs a tool to decide about drilling of new public or private wells, in order to avoid significant interferences in the present system. This paper relates a building and an application of a computing program connected with drawdown calculations, allowing to evaluate interferences il1 well systems. The program was build in EXCEL 7.0, using the Visual Basic programming language. The idea of buildmg a new program, easy to apply, as in values i.nlet and results display, is justified because present programs usually demands advanced knowledge on computing mathematic area (finite elements and fmite differences). The il1terference calculations performed by the program bases in well functions theory and the evaluation of total drawdow11s is done by the theory of superposition. The results of using it at evaluations o f well systems are presented, allowing to estimate pumping effects at the piezometric surface drawdown.

Determinantes da proficiência em matemática no Rio Grande do Sul: uma análise a partir de modelos hierárquicos

O presente trabalho tem como objetivo investigar os fatores associados ao desempenho escolar no Estado do Rio Grande do Sul, utilizando modelos hierarquicos lineares (MHL) e os microdados do Sistema de Avaliacao do Rendimento Escolar (SAERS) do ano de 2007. O principal resultado evidenciou que as caracteristicas socioeconomicas dos alunos estao fortemente associadas ao desempenho escolar, enquanto que as caracteristicas das escolas pouco contribuem na explicacao do rendimento escolar dos estudantes gauchos. Nao necessariamente esse resultado significa que as caracteristicas escolares nao sao importantes na explicacao da proficiencia, mas pode sinalizar um uso ineficiente dos recursos escolares. Verifica-se que e importante desenvolver estrategias que orientem politicas publicas, no sentido de ampliar o papel da escola no desempenho dos estudantes, de modo a proporcionar igualdade de oportunidades, sobretudo para os alunos mais carentes. Palavras-chave Economia da Educacao; desempenho escolar; modelos hierarquicos lineares TITULO EM INGLES Determinants of the proficiency in math in the State of Rio Grande do Sul: an analysis based on hierarchical models Abstract This paper aims to investigate the determinants of educational achievement in the State of Rio Grande do Sul, Brazil, by using hierarchical linear models (HLM) and the 2007 microdata from the Sistema de Avaliacao do Rendimento Escolar do Rio Grande do Sul (system of educational performance assessment of the State of Rio Grande do Sul). The main result points to the students’ socioeconomic characteristics as the strongest determinants of their performance, while school features contribute very little to their outcomes. This result does not necessarily mean that school attributes are not important to explain the students’ results, but it might mean that school resources have been used inefficiently. The evidence shows that it is important to develop strategies to guide public policies in order to expand the role of the school in the students’ achievements, so that they, especially the neediest ones, can be given equal opportunities.

Weiterbildung in Deutschland: Engagement der Betriebe steigt weiter

 Knapp ein Viertel der Kleinstbetriebe mit weniger als zehn Mitarbeitern engagiert sich auch über einen längeren Zeitraum nicht in der Weiterbildung. Allerdings beziehen kleine Betriebe, die sich an der Weiterbildung beteiligen, relativ viele ihrer Mitarbeiter ein. Damit ist die durchschnittliche Weiterbildungsteilnahme der Beschäftigten aus kleinen und großen Betrieben insgesamt nahezu gleich.
