Paperback. Condizione: new. Paperback. The number of robots applied to different jobs in our society has steadily increased over the past years. While industrial robots welding and varnishing our cars are quite common these days, the future generation of robots will enter our everyday life. In contrast to industrial robots working in special evacuated areas for security reasons, these mobile service robots will have to move among and interact with humans, imposing new challenges on the software of the robots. Only the application of sensors to observe the environment and the subsequent use of intelligent data processing algorithms will enable the robots to avoid collisions with moving obstacles, to get information on their current locations, to perform goal oriented tasks and to cooperate with humans as well as other robots.This thesis addresses these new challenges by describing the development of a team of robots that is able to exhibit intelligent behavior, competitive as well as cooperative, while moving in a highly dynamic environment, as a first step towards a new kind of mobile robots. To evaluate and compare the results of the development, robotic soccer (RoboCup) was chosen as testbed for the robot team.Many of the challenges imposed by the RoboCup environment are similar to those found in real-life applications. Robots in RoboCup have to localize themselves, gather information on their environment, including the position and also the velocity of potential obstacles, deal with varying lighting scenarios, as well as competing and cooperating with other robots. Firstly, the thesis presents the decisions made concerning the co-design of the robot hardware and software. Here, the selection of an omni-directional drive mechanism and a vision sensor with a high frame rate, the software framework designed to be flexible and expandable, as well as the development of a common and simple control interface are the key points in the system design. The main part of the thesis, however, presents the efficient algorithms implemented for image processing, environment modeling, and high-level control. As the only sensor of the robots is an omni-directional vision system that is able to map the complete surrounding of the robot, the performance of the robot system depends on the image processing algorithms and requires a high accuracy and a low processing time.The presented image processing algorithms fulfill both requirements proven by extensive experimental results. Besides landmark and object extraction these algorithms also include new techniques for automatic camera calibration. The environment modeling contains a new combined Monte-Carlo localization and tracking algorithm that is competitive with the best performing algorithms concerning the accuracy and the computation time at the same time, again proven by extensive experimental results. Finally, the high-level robot control component exhibits efficient movement through highly dynamic environments and successful competitive and cooperative behavior. The thesis concludes with an analysis of the team's RoboCup competition results as a final verification of the good performance of the developed system.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Doctoral Thesis / Dissertation from the year 2022 in the subject Engineering - Civil Engineering, grade: Summa cum laude, , language: English, abstract: Steel structures, which are made of hollow section profiles are mainly used for construction structures. There are many fields of applications for structures made of hollow section profiles. Hollow section profiles are lightweight and have got a high resistance to compression, which is an advantage for column structures. The most common profile types have squared or circular hollow cross sections. Connecting two or more pipes by welding, the joints have got different shapes. These joints are part of trusses or columns with a tree-shaped optic. The standards have got restrictions regarding the geometry, material or load cases. By choosing a node, which is excluded in the standards, designing engineers have to create their own models. This thesis is about the designing of a Y-shaped steel joint, full overlapped on top connection, which is not defined in current standards up to the time the thesis is created. In this thesis only uniplanar joints are investigated. A special focus is on the welding line, which has got a three-dimensional shape. The aim is to figure out the influence on the inclination angle between the two members on the resistance of the joint. Beside this, the profile shape and profile thickness vary to see the differences in their resistance. Square and circular hollow section profiles are in focus. To analyse the behaviour of the different steel joints, a numerical and experimental investigation is executed. Design charts are created as a medium for designing engineers to calculate the ultimate resistance in the elastic and plastic state, depending on the steel profile, thickness and inclination angle. The structure of the thesis is split into four main parts. Firstly, there is an explanation of the general topic with its difficultness. Secondly, there is the state-of-the-art presentation of literature and standards in this range. Thirdly, there is a numerical analysis of the joints. The basement of the numerical studies is detailed in pre-studies, which explain and compare different mesh types or geometrical variations. Fourthly, there is an experimental verification of the numerical tests. It is figured out, if the inclination angle increase, the resistance of the steel joint will decrease significantly. This effect is non-linear. Beside this, it is found, that the full overlapped joint with the squared profile has got a higher resistance than a comparable joint with a similar circular hollow section.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Management accounting information serves as a primary information source for managers and is a powerful resource for strategic decision-making and influence processes on all organizational levels.Patrick Heinemann combines and extends the research on power and influence from social psychology with insights from scholarly works on the use of information. He derives hypotheses on the relationships between influence strategies based on management accounting information, influence outcomes, and various moderating variables. In a sample of top-level managers of a large German utility provider, the author tests these theoretical relationships using the Partial Least Squares approach to structural equation modeling. The results highlight the importance of understanding power relationships in organizations and the ways in which management accounting information can be used for successfully influencing subordinates.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book is a collection of papers describing some of the first attempts to apply the techniques of recombinant DNA and molecular biology to studies of the nervous system. We believe this is an important new direction for brain research that will eventually lead to insights not pos sible with more traditional approaches. At first glance, the marriage of molecular biology to brain research seems an unlikely one because of the tremendous disparity in the histories of these two disciplines and the problems they face. Molecular biology is by nature a reductionist approach to biology. Molecular biologists have always tried to attack central questions in the most direct approach possible, usually in the most simple system available: a bacterium or a bacterial virus. Important experiments can usually be repeated quickly and cheaply, in many cases by the latest group of graduate students entering the field. The success of molecular biology has been so profound because the result of each important experiment has made the next critical question obvious, and usually answerable, in short order. Studies of the nervous system have a very different history. First, the human brain is what really interests us and it is the most complex structure that we know in biology. The central question is clear: How do we carry out higher functions such as learning and thinking How ever, at present there is no widely accepted and testable theory of learn ing and no clear path to such a theory.
