At present state, almost the industrial robot tasks are performed by the teaching playback method, in which the robot repeats positioning its joint angles, which are taught manually in advance using a teaching pendant, etc. This method is based on comparatively high repeatability of a robot arm. The problem here is that the laborious and time-consuming online manual teaching is inevitable whene...

In this study, an automated adaptive mesh control scheme, based on local mesh modifications, is developed for the finite element simulations of 3D metal forming processes. Error indicators are used to control the mesh discretization errors, and a consecutive h-adaptive procedure is conducted. The mesh size field used in the h-adaptive procedure is processed to control the geometric approximatio...

A task-oriented system structure has been developed. In normal industrial robot programming, the path is created and the process is based on the path. Here a process-focused method is proposed, where a task can be split in sub-tasks, one for each part of the process with similar process-characteristics. By carefully encapsulating the information needed to execute a sub-task, this component can ...

Factorial experiments are widely used in industrial experimentation and other fields. Whenever a factorial experiment is not designed as a full factorial but as a – regular or non-regular – fraction thereof, choice between competing designs and interpretation of experimental results should take into consideration how the experimental plan will confound experimental effects. This article propose...

A core goal for autonomous systems such as that proposed here is automated collaboration in order to perform tasks or share information. The system is always distributed by default and frequently on a large-scale. It can be argued that robustness and economy demand the deployment of a tested autonomic supporting infrastructure whenever possible. Industrial systems middleware is generally modula...

Empirical evidence is given for a significant difference in the collective trend of the share prices during the stock index rising and falling periods. Data on the Dow Jones Industrial Average and its stock components are studied between 1991 and 2008. Pearson-type correlations are computed between the stocks and averaged over stock pairs and time. The results indicate a general trend: whenever...

This research examines how the South Korean cable television industry has developed. The research reviews a brief history of the South Korean broadcast television system and examines the U.S. cable television system to provide better understanding of the development of the South Korean cable television. The research explains policies, laws, industrial structure, and three issues of localism, co...

The departure from the current automation landscape to next generation automation concepts for the process industry has already begun. Smart functions of sensors simplify their use and enable plug-and-play integration, even though they may appear to be more complex at first sight. Smart sensors enable concepts like self-diagnostics, self-calibration, and self-configuration/parameterization when...

In this paper we study the two-dimensional non-guillotine cutting problem, the problem of cutting rectangular pieces from a large stock rectangle so as to maximize the total value of the pieces cut. The problem has many industrial applications whenever small pieces have to be cut from or packed into a large stock sheet. We propose a tabu search algorithm. Several moves based on reducing and ins...
