This paper deals with the description of pilot operational work of the system for heat energy collection from thermally active mining dump Hedvika. It describes particular technologies for heat collection including the system for use of the gathered heat energy in the form of hot water. It also describes the measurement system that monitors thermal activity of the mining dump at the location of heat...
Thin-walled parts are easy to deform during the machining process. The machining conditions of such parts are difficult to monitor since both tool wear and work-piece deformation need to be carefully monitored. Usually, the characteristic vector constructed based on monitoring signals can be deemed as the basis to recognize different machining conditions. In order to construct the characteristic vector,...
This paper focuses on supervisory control of a class of discrete event systems with known initial and destination states, whose evolution conforms to a set of specified linear or non-linear constraints. A supervisor is designed, which supervises the considered system to evolve and finally to reach the destination state with minimal costs without violating the specified constraints. A partial structure...
This paper proposes a divide-and-conquer method to synthesize non-blocking supervisors for a class of generalized Petri nets, namely G-system. A novel deadlock prevention method is presented by utilizing the reachability graph (RG). Due to the RG of a large Petri net model (PNM) easily becomes unmanageable, an optimal non-blocking supervisor based on RG becomes a challenging problem in a generalized...
This paper addresses the design of an on-off control strategy for operating robots in a cyclic flow shop plant. The main goal is to properly switch off and on the robots to save energy consumption without any reduction of the plant desired throughput. To fulfill this goal, first mathematical conditions, which characterize movement of parts in the plant and the on-off control for robots, are presented...
The Health At Home (HAH) is an alternative to the traditional hospital to promote the early discharge and to help patients and elderly people to live autonomously. This paper specifies and models an Integrated System (IS) devoted to the HAH management at the operational level. The IS is designed to monitor the daily living of the apartment inhabitant, detect the possible troubles and accidents, communicate...
In order to cope with system complexity and dynamic environments, modern industries are investing in a variety of sensor networks and data acquisition systems to increase information visibility. Multi-sensor systems bring the proliferation of high-dimensional functional profiles that capture rich information on the evolving dynamics of natural and engineered processes. This provides an unprecedented...
In the Prognostics and Health Management domain, estimating the remaining useful life (RUL) of critical machinery is a challenging task. Various research topics as data acquisition and processing, fusion, diagnostics, prognostivs and decision are involved in this domain. This paper presents an approach for estimating the Remaining Useful Life (RUL) of equipments based on shapelet extraction and characterization...
In this paper, we propose a gait analysis based walking stabilization system on an active robotic walker for Parkinson's Disease patient. We developed a vision based gait analysis that lower limbs from the frontal view which is captured by single RGB-D camera on the robotic walker. Our system constructs the lower limbs skeleton and kinematic model for calculating the walking gait features such as...
With the increasing percentage of elderly population in modern society, more attention is paid to improve the living quality for elderly who live alone at home. However, most home care units were designed to tackle single problem, not omni and real-time systems, faced at home. This study proposes an intelligent approach to identify elderly body information. Two sub-modules, fingertip temperature measurement...
In the industry, effectively improve the speed of production management and troubleshooting information quickly and efficiently share representatives do have better productivity, and thus may bring more cash flow. Except for the Storage and Cloud Computing concept of Cloud Platform, this paper provided new point about sharing issue. A good share resources available way to multinationals, can successfully...
