in this paper, the flexible job shop scheduling problem with machine flexibility and controllable process times is studied. the main idea is that the processing times of operations may be controlled by consumptions of additional resources. the purpose of this paper to find the best trade-off between processing cost and delay cost in order to minimize the total costs. the proposed model, flexibl...

We are concerned with time space signal processing in CDMA system, which uses specific receiving configuration with RAKE receivers. This configuration is improving the system performances while decreasing the system capacity. Antenna array could provide capacity improvement while keeping the good performances from time processing. Actually this is conventional time space signal processing perfo...

To test whether atypical number development may affect other types of quantity processing, we investigated temporal discrimination in adults with developmental dyscalculia (DD). This also allowed us to test whether number and time may be sub-served by a common quantity system or decision mechanisms: if they do, both should be impaired in dyscalculia, but if number and time are distinct they sho...

For thousands of years engineers have dreamed of building machines with vision capabilities that match their own. However most image processing algorithms are computationally intensive making real-time implementation di cult, expensive and not usually possible with microprocessor based hardware. In this project a computationally intensive image-processing algorithm is implemented, analysed, and...

abstract background: the radiographic image accuracy depends on the x-ray film information visibility. good visibility is found by good contrast. radiation exposure parameters (kvp, mas) and film processing conditions have impact on contrast. in dentistry radiography machines, exposure time and processing procedure are set by radiographer. no optimized exposure time and processing conditions ma...

This paper considers identical parallel machines scheduling problem with past-sequence-dependent setup times, deteriorating jobs and learning effects, in which the actual processing time of a job on each machine is given as a function of the processing times of the jobs already processed and its scheduled position on the corresponding machine. In addition, the setup time of a job on each machin...
