Researches Regarding the Use of Elctrohydraulic Servosystems at Industrial Robots

2012

This paper presents some researches regarding the use of electro-hydraulic servo-systems in driving the industrial robots, taking into consideration the conditions in which the robots work. The researches conducted upon a particular system, reveal the optimum design elements for obtaining a good behaviour in use, subsequently a good stability in use.

Parental role models and the decision to become self-employed: The moderating effect of personality

2010

This paper uses social learning theory to examine the influence of parental role models in entrepreneurial families. We distinguish between paternal and maternal role models and investigate how their influence on offsprings’ decision to become self-employed is moderated by personality, specifically the offsprings’ openness. We use data on 461 alumni from eight German universities. Our results show not only that the presence of a parental role model increases the likelihood that individuals become self-employed, but that the influence of role models also depends on the individual’s openness. We discuss the implications of our findings for research on entrepreneurial families, role models, an…

Evolutionary Game Dynamics for Collective Decision Making in Structured and Unstructured Environments

2017

Abstract For a large population of players we consider a collective decision making process with three possible choices: option A or B or no option. The more popular option is more likely to be chosen by uncommitted players and cross-inhibitory signals can be sent to attract players committed to a different option. This model originates in the context of honeybees swarms, and we generalise it to accommodate other applications such as duopolistic competition and opinion dynamics. The first contribution is an evolutionary game model and a corresponding new game dynamics called expected gain pairwise comparison dynamics explaining how the strategic behaviour of the players may lead to deadlock…

Nash codes for noisy channels

2012

This paper studies the stability of communication protocols that deal with transmission errors. We consider a coordination game between an informed sender and an uninformed decision maker, the receiver, who communicate over a noisy channel. The sender's strategy, called a code, maps states of nature to signals. The receiver's best response is to decode the received channel output as the state with highest expected receiver payoff. Given this decoding, an equilibrium or "Nash code" results if the sender encodes every state as prescribed. We show two theorems that give sufficient conditions for Nash codes. First, a receiver-optimal code defines a Nash code. A second, more surprising observati…

Probabilistic and team PFIN-type learning: General properties

2008

We consider the probability hierarchy for Popperian FINite learning and study the general properties of this hierarchy. We prove that the probability hierarchy is decidable, i.e. there exists an algorithm that receives p_1 and p_2 and answers whether PFIN-type learning with the probability of success p_1 is equivalent to PFIN-type learning with the probability of success p_2. To prove our result, we analyze the topological structure of the probability hierarchy. We prove that it is well-ordered in descending ordering and order-equivalent to ordinal epsilon_0. This shows that the structure of the hierarchy is very complicated. Using similar methods, we also prove that, for PFIN-type learning…

Factor structure and stability of a quality questionnaire within a postgraduate program

2017

En este trabajo se describe un instrumento basado en el uso de una técnica de análisis factorial con el fin de medir la calidad de la educación a través de una muestra de estudiantes de postgrado de una universidad pública española. El instrumento tiene unas aceptables propiedades psicométricas (fiabilidad y validez). En cuanto a la solución factorial, tres dimensiones principales se han determinado: la importancia dada a la materia; recursos educativos y conocimiento de la materia (anterior y posterior). Es importante destacar que estas tres dimensiones se han detectado consistentemente en todo el análisis factorial: muestra total y cursos separados. Estas tres dimensiones deben ser consid…

Replacing radiative transfer models by surrogate approximations through machine learning

2015

Physically-based radiative transfer models (RTMs) help in understanding the processes occurring on the Earth's surface and their interactions with vegetation and atmosphere. However, advanced RTMs can take a long computational time, which makes them unfeasible in many real applications. To overcome this problem, it has been proposed to substitute RTMs through so-called emulators. Emulators are statistical models that approximate the functioning of RTMs. They are advantageous in real practice because of the computational efficiency and excellent accuracy and flexibility for extrapolation. We here present an ‘Emulator toolbox’ that enables analyzing three multi-output machine learning regress…

Improving scalability of web applications based on stability of the network with the use of controller PI

2015

This paper presents mathematical model of a computer network and then the model has been presented in the form of a flow chart. RED algorithm is a standard in computer network. RED algorithm has been replaced with the PI controller. In the article it has been assumed that a computer network is a particular dynamic system and it can be examined using known methods of the theory of dynamic systems. We tested of stability for the real computer networks. This method is called method the uncertain parameters space.

The authenticity of ‘authentic’ assessment some faculty perceptions

2017

The attempt to embed Authenticity within the learning process in higher education has been a driving principle within many pedagogical approaches to Higher Education developed over the past three decades. The desire to allow students to learn in a manner that closely resembles the way in which expertise is developed outside the academic environment is a central element of problem-based, inquiry-based and projectbased learning. Exploring the implications of authenticity for student achievement and the ways in which this should be assessed has led to innovative teaching methods and ways of evaluating student performance. Unfortunately, authenticity, and authentic assessment in particular, are…
