Galaxy formation: from primordial fluctuations to structure formation in the Universe

Durante questa tesi studieremo principalmente i modelli di formazione di struttura nel universo di Press & Schechter(1974) e di White & Rees (1978), che spiegano la formazione galattica con un modello gerarchico di formazione di tutte le strutture cosmiche, dalla crescita delle piccole perturbazioni primordiali fino alla formazione della materia, e come essa si evolve per formare stelle e poi sistemi stellari, cioè, galassie. Una parte importante di questa tesi sarà dedicata a studiare la formazione di aloni di materia oscura, che sono vere e proprie buche di potenziale, in cui la materia barionica caderà per formare la galassia. Finalmente, studieremo la formazione di strutture luminose, come sono le stelle, al interno degli aloni di materia oscura ed a cos'è dovuto le diverse morfologie che vediamo in diverse galassie. Confronteremo i risultati più importanti dei modelli teorici studiati con dati osservativi ed esperimentali moderni

Robert Walser

Las Prosastücke o Prosas de Robert Walser fueron publicadas por primera vez en 1916, en los cuadernos Schriften für Schweizer Art und Kunst de la editorial Raschen, y una vez más, como volumen independiente, en 1917 por la misma casa editora. Vuelto autor de culto, remitimos al lector a los textos de escritores como Elías Canetti, Walter Benjamin o Roberto Calasso; este último afirma en “El sueño del calígrafo”, a propósito de su obra más conocida, Jakob von Gunten: “[Walser] dirige su mirada sobre todo a los acontecimientos minúsculos, a la vida diseminada, a todo lo que es irrelevante: el tono de las cosas que pasan y se borran por sí solas. A Walser el símbolo no le merece más que una sonrisa desdeñosa”

Ingeborg Bachmann

Estos poemas de Ingeborg Bachmann (Klagenfurt, 1926-Roma, 1973) fueron escritos entre 1964 y 1967, y no fueron recopilados originalmente en libro alguno.1 Corresponden a una época de transición en la escritura de Bachmann, que servirá como preludio a la prosa fragmentaria y compleja de la novela Malina (1971)

A Versatile Method of Resolution Enhancement for Tactile Sensor Array Used as Synthetic Skin: Modeling and Implementation

Tactile sensors are one of the major devices that enable robotic systems to interact with the surrounding environment. In particular, modern assistive robotic systems need to carry out many human-like activities. Thus, it is desired to have sensor arrays that can acquire different environmental information just like human skin. In the past two decades, various types of tactile sensor arrays have been developed to acquire different physical properties, such as temperature, force, and geometric shapes. However, though the measurement of a single sensor can be accurate, the planar resolution is limited due to fabrication difficulties. This research aims to propose a mathematical model to describe the behavior of a tactile sensor based on experimental and statistical analyses. Moreover, to develop a versatile algorithm that can be applied to different tactile sensor arrays to enhance the limited resolution. With the proposed algorithm, the resolution can be increased up to twenty times if multiple measurements are available.;To verify if the algorithm can be used for tactile sensor arrays that are used in robotic system, a 16 x 10 force sensing array (FSR) is adopted. The force was first measured by a scanning data acquisition device integrated by a synthesized electronic circuit, DAQ station and an interface developed using MATLAB. The acquired two dimensional measurements were then processed by the Proposed Resolution Enhancement Algorithm (PREA) to enhance the resolution. The proposed algorithm can be used to improve the resolution for single image or multiple measurements. In this study, the developed MATLAB scripts can automatically identify the location of the targeted objects if multiple measurements are recorded. As a result, the resolution of the sensor is increased and it can be used as synthetic skin to identify accurate shapes of objects and applied forces

The relationship between kinship support services and placement outcomes

This study examined the relationship between kinship support services and placement outcomes using secondary data collected by Chang and Liles (2004) in the Counties of San Bernardino and Riverside. This study aimed at assessing kinship care placement outcomes by reviewing the characteristics of kin caregivers and their dependent children, types of financial support and services received, and contact with social workers. This study sample included 130 kinship caregivers and 291 dependent children from the original study (Chang & Liles, 2007)
