Integration von Fremdsoftware wird zunehmend zu einer Schlüsselfähigkeit der Automobilzulieferer, die es effizient zu beherrschen gilt. Hierbei existiert ein breites Spektrum von Anwendungsfällen mit unterschiedlichsten Anforderungen an Sicherheit (im Sinne von Safety und Security) und Zuverlässigkeit. Beispiele reichen von extern entwickelten Komfortfunktionen bis zu Softwarekomponenten des OE...

This paper is intended to be pedagogical rather than a presentation of original research. We describe a simple dynamic, stochastic general equilibrium (DSGE) model with capital utilization, capital adjustment costs, and a simple Cobb-Douglas technology to illustrate how DSGE models can be used to explain the past and to forecast the future. We identify one method to directly estimate latent var...

The question of t,he operation of large-scale controls in day-to-day weather map evolutions is discussed. To explore the usefulness of these concepts in daily forecasting, the problem of forecasting the passage of summertime r-Id fronts at Kansas City is used. More-or-less standard techniques are used to develop an objective method of forecasting these frontal passages, and its deficiencies are...

In [40], it was shown that the following singularly perturbed Dirichlet problem 2∆u− u+ |u|p−1u = 0, in Ω, u = 0 on ∂Ω has a nodal solution u which has the least energy among all nodal solutions. Moreover, it is shown that u has exactly one local maximum point P 1 with a positive value and one local minimum point P 2 with a negative value and, as → 0, φ(P 1 , P 2 ) → max (P1,P2)∈Ω×Ω φ(P1, P2), ...

We argue that an increase in the number of specialized consumers can shift the control of ecological dynamics from local to spatial processes. When there are only a few specialized types, local dynamics maintains most types within each patch. As the number of types increases, the probability of local extinction rises. Subsequent colonizations perturb local dynamics, setting off another round of...

Variable Neighborhood Search (VNS) is a recent metaheuristic, or framework for building heuristics, which exploits systematically the idea of neighborhood change, both in the descent to local minima and in the escape from the valleys which contain them. In this tutorial we first present the ingredients of VNS, i.e., Variable Neighborhood Descent (VND) and Reduced VNS (RVNS) followed by the basi...

This paper gives an overview of methods for utilizing large process data matrices. These data matrices are almost always of less than full statistical rank, and therefore latent variable methods are shown to be well suited to obtaining useful subspace models from them for treating a variety of important industrial problems. An overview of the important concepts behind latent variable models is ...

this study examined the effect of general and specific practice on the presence of a special skill. 24 healthy university students with no history of basketball were selected. after a pretest, they performed constant and variable practice (in constant and variable groups) for 5 weeks and 3 sessions per week. a performance test was conducted at the end of every week and retention and transfer te...

Variable neighborhood search (VNS) is a metaheuristic, or framework for building heuristics, based upon systematic change of neighborhoods both in a decent phase to find a local minimum, and in a perturbation phase to get out of the corresponding valley. It was first proposed in 1997 and since has rapidly developed both in its methods and its applications. Both of these aspects are thouroughly ...

Control chart techniques have been widely used in industries to monitor a process in quality improvement. Whenever we deal with variables data, we usually employ a combination of X-bar chart and R chart (or S chart) to monitor both the center and the spread of the process. In this paper, we propose a simple alternative, that is, we design a single chart to monitor both the center and the spread...
