The focus of this paper is to present an architecture for the seamless integration of devices in Small and Medium Enterprises (SMEs). Our proposal intends to cover any device, regardless of manufacturer or technology level. In this scenario, small lot sizes and the fast adaptability of the production environment is more important than short cycle times. Moreover, the ability to incorporate new devices smoothly must be considered in order to reduce adaptation costs in an otherwise stablished production environment. This is the main difference of our approach when compared, for instance, to the European Union's Sixth Framework Programme (FP6) called SMErobot1. Control Architecture for Device Integration (CADI), although a much modest project, proposes a more flexible approach for transitioning an stablished production environment from a current technology level into a more flexible and automated environment, without the need for an overall adaptation of the work cell and the acquisition of all new equipment. This paper presents CADI's architecture in the form of its subsystems: the tag subsystem, the device proxy and the work cell controller.

This research is aimed at achieving human consciousness in a robot. The authors focus on mirror image cognition, which is a high-level conscious function of humans, and have been conducting mirror image cognition tests with the robot, and have discovered that emotion and feelings are closely related to decision-making and learning. However, do humans always decide on an action through their emotions? Most probably, people learn from their experiences and decide on an action by expecting the future status using past experiences. Consciousness and memory are closely related to each other, and are important factors also in achieving consciousness in a robot. The present paper discusses human consciousness, episodic memory, one of the memory functions, and expectation. It also reports on the study of a conscious robot that incorporates all of these elements.

Today technical product documentation and also related product use phase feedback contain valuable information about the company's products. In addition processing of various types of feedback provides opportunities for improvement potentials in product development especially in the next product generation and for increasing customer satisfaction. In this context, the acquired information is the key source of procedural knowledge particularly in product life cycle/data management. In the previous publications [1], [2] various knowledge based methods/functions like Bayesian Network, Dynamic Bayesian Network and Aggregation are presented, based on a kind of Assistance System for integration of product use information into product development. This paper presents a data integration approach through establishing an Assistance System for steel industry applications particularly for moderating of heat treatment process. In addition, a concept for using indicator systems for evaluating the performance of the Assistance System and particularly information quality is presented.

One of the problems for development of industrial controls programs is the availability of the actual equipment to be controlled. Availability of the equipment may be due to project timing, cost issues, and even location. By using a simulation tool, integrated with the control programming environment, the control engineer can test the control program functionality to reduce the amount of time required to commission and deploy the system. Dependent upon the complexity of the system and simulation, diagnostic programs can be developed and tested. Additionally, as new control system capabilities are developed, the corresponding simulation model can be adapted to test those new capabilities. In this paper, we describe the development, use, and validation of an integrated control and simulation tool for an anaerobic digester lab system. Results of the validation tests are discussed, as well as the methods used to develop and deploy the control program. Finally, future work is described to use the capabilities of the control and simulation tool as a formal validation step in the control system design and commissioning.

The authors have developed a system to autonomously classify the meanings of words using a knowledge database constructed from sentences found in textual content on Internet websites. This is a totally new system for classifying the meanings of words dynamically using only the connections between words. The authors believe that robots using such a system can approximate the knowledge of humans.

Safety is an element of extreme priority in mining operations, currently many traditional mining countries are investing in the implementation of wireless sensors capable of reducing the number of accidents; through early warning signs to prevent injuries, dead and significant economic losses. The application of sensors capable of measuring in real time variables of interest, promises to be of great impact on safety for mining industry. In this publication analyzed the main causes of accidents in coal mining underground, the technical issues to implement an efficient monitoring program of collapses and gases into underground mining. Issues related with the advantages, management and mine operations are discussed, including the analysis of Benefit, Opportunity, Cost and Risk. The publication will focus on coal mines, because these seem to be most accident prone underground mining environments. However, many of the reported results can be extrapolated to other mining activities.

This paper presents a new slack-time based algorithm for dual Vdd design to achieve maximum energy saving. Although a global optimum is sought computation time is kept low. The slack of a gate is defined as the difference between the critical path delay for the circuit and the delay of the longest path through that gate. A linear-time algorithm is used for computing slacks for all gates of the circuit. Positive non-zero slack gates are classified into two groups, one in which all gates can be unconditionally assigned low voltage and the other where only a selected subset can be assigned low voltage without violating the positive non-zero slack requirement. Multiple voltage boundaries are given special consideration. The overall complexity of this power optimization algorithm is linear in number of gates as compared to a previously published exponential-time exact algorithm using mixed integer linear program (MILP). We apply the new algorithm to optimize ISCAS'85 benchmark circuits and compare the results with those from MILP. We avoid the use of level converters at multiple voltage boundaries. Energy savings from the new slack-time based algorithm is very closed to those from MILP. For c880, the energy saving is 22% for subthreshold voltage operation and 50% for nominal operation in PTM CMOS 90nm. For c2670 nominal voltage design, time of dual voltage optimization is reduced 43X compared to the MILP method. This new algorithm is beneficial for large circuits with many large positive slack paths that would require enormous time for optimization by the MILP approach.

The performance of an enterprise largely depends on the schedule of its resources. A good schedule may increase the output rate and reduce the production costs. Therefore, in this paper, we consider the cyclic schedule of hoist activities in automated electroplating lines which is commonly known as Cyclic Hoist Scheduling Problem (CHSP). The CHSPs appear in the manufacturing facilities to achieve a mass production and to search a repetitive sequence of moves for the hoist. In such kind of lines, hoist is used for moving electroplates through a line of tanks containing chemical baths. In this paper, we extend our elaborated 2-degree cyclic linear model to a more complex configuration of the production lines.

This paper investigates the application to the provision of integral discrete sliding mode tracking control with input constraint for engine idling speed control because the control logic are always implemented in discrete-time by microprocessors. The subject of this experiment is to improve the stability of the system against disturbances such as fuel purges and torque loads. A discrete Sliding mode control based on servo system is employed that effectively remove the steady-state error when the bias power disturbance occurs. The control logic also concluded a design of feedback compensation gain, derived from the control input difference, to compensate for control input constraint. A mean-value engine model combined with dead time and superimposed disturbances was constructed in Matlab/Simulink. The simulation results showed the issue relating to steady-state deviation was successfully solved under the disturbances having bias power, and also robustness was maintained during engine speed fluctuations.
