Integration of GIS,GPS, and optimization technologies for the effective control of parcel delivery service

An intelligent monitoring and control system for parcel delivery service is described in this paper. To manage pick-up and delivery operations more effectively, geographical information system (GIS), global positioning system (GPS), and wireless communication technologies are applied to the system which consists of three subsystems, pick-up and delivery sequence planning system, pick-up and delivery monitoring system, and PDA execution system. Pick-up and delivery sequence planning system generates routes and schedules for pick-up and delivery using GIS and optimization techniques.

Management scheme of a workstation controller in a flexible manufacturing system

A workstation controller is an industrial computer which controls the function of the unit workstation in a flexible manufacturing system. A workstation is considered a functionally cohesive group of machine equipment and the operation is carried out independently. The basic operating unit in a workstation controller is the computer program. In other words it is a task. A set of software tools has been defined, developed, and tested for a workstation controller. The tasks create a workstation domain which makes the user application that controls and monitors the workstation operation. A specific program called Configuration Manager, consisting of various modules, is responsible for supervising the tasks within a workstation controller. Usually, a single Configuration Manager resides in a workstation controller. However, multiple Configuration Managers can be utilized in several CPU boards in a common backplane. The program has been developed on a realtime operating system to fit into the realtime environment of a manufacturing system. The Configuration Manager is written in the “C” programming language to enhance the portability. However, the user application software could be written in any higher level language.

This medical workstation aims to provide an environment for optimal interpretation of multiple noninvasive image modalities by combining functional PET, MRS, and MEG information with structural MRI anatomy both qualitatively and quantitatively. Since there is currently little knowledge relating to the positive and negative findings of various imaging and intracranial EEG studies on patient populations, the data extracted will also help in outcome analyses to identify inefficient or duplicative evaluation procedures

Controlling a Wheelchair Indoors Using Thought

Amyotrophic lateral sclerosis, or ALS, is a degenerative disease of the motor neurons that eventually leads to complete paralysis. We are developing a wheelchair system that can help ALS patients, and others who can't use physical interfaces such as joysticks or gaze tracking, regain some autonomy. The system must be usable in hospitals and homes with minimal infrastructure modification. It must be safe and relatively low cost and must provide optimal interaction between the user and the wheelchair within the constraints of the brain-computer interface. To this end, we have built the first working prototype of a brain-controlled wheelchair that can navigate inside a typical office or hospital environment. This article describes the BCW, our control strategy, and the system's performance in a typical building environment. This brain-controlled wheelchair prototype uses a P300 EEG signal and a motion guidance strategy to navigate in a building safely and efficiently without complex sensors or sensor processing     

Conceptual design of remote monitoring and fault diagnosis systems

Condition monitoring and fault diagnosis are of fundamental importance for many industrial systems. In the last decade, substantial research efforts have been made on the surveillance and diagnosis systems for different types of equipment, with the approach of integrating information technologies and intelligent computing methods. This paper presents the conceptual design of a distributed information system of condition monitoring and fault diagnosis for a growing number of gas turbine-based power generation systems. Each individual information system that monitors a specific gas turbine system, locally deployed in a power plant, is linked to another information system, deployed at the manufacturer's site, which oversees all the gas turbine systems in parallel. The systems are constructed on the basis of COM components, which are conceptually separated into three tiers. Subsequently, this paper proceeds to present a generic business domain model with components encapsulating physical entities of interest. Finally, this paper addresses the interactions among components, which considerably affect the performance of the system including efficiency and effectiveness. It has been identified that both asynchronous and synchronous communication mechanisms are required for exchanging information for different scenarios. COM+ services are also required for supporting object pooling, transaction coordination, and security control.
