the existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

the research used the satellite image (landsat 7 etm ) within the thermal infrared sixth band (tir6) and geographic information system (gis) to determine the air pollution and its relationship with the land cover (lc) and land use (lu) of baghdad city. concentration of total suspended particles (tsp), lead (pb), carbon oxides (co, co2), and sulphur dioxide (so2) were obtained from 22 ground mea...

Her research focuses on human factors and applied psychology, with an emphasis on understanding team performance in high-risk healthcare settings. Dr. Parker is currently an AHRQ postdoctoral fellow, researching team coordination during trauma resusc...

The main focus of this study has been on the development of a conceptual framework for improving the current status of industrial accidents’ control. The framework is aimed to use of ICT to improve the information exchange between the Civil Defence and Industrial Sector and to provide an information management system model for the Industrial Incidents Administration System (IIAS). The purposed ...

This work presents the prototype of a standard for HVDC, designed to be used in the range of 1kV to 50 kV and calibrated in low voltages. In HV, it will be the link in the chain of traceability between the INMETRO standard and the dividers used by industrial laboratories.

In this project a mobile autonomous robot is developed that navigates and fulllls transportation tasks in dynamically changing industrial environments. Three obligatory ingredients are a goal-directed robot control architecture, a position-estimation mechanism for navigation purposes, and a wireless communication link to other robots and a control center.

Over past decades industrial IT evolved separately in the field automation and office automation domains. Nowadays increasing complexity of manufacturing requiresmore advanced control, which can be achieved only by integrating these, formerly separated, areas. This article focuses on two aspects of such integration: communication-related, interconnecting networks of different kinds, and functio...
