Remote, telecommunications based support for process equipment operation and maintenance can offer substantial benefits for the end-user in terms of improved uptime and better quality of operation. Equipment vendors can utilize this kind of facility to improve their after-sales services for the end-user. A remote operations support system has been designed and realized. The prototype system has...

Nowadays, dynamic service management frameworks are proposed to ensure end-to-end QoS. To achieve this goal, it is necessary to manage Service Level Agreements (SLAs), which specify quality parameters of the services operation such as availability and performance. This work is focused on the evaluation of Video-on-Demand (VoD) services in end-to-end QoS scenarios. Based on a straightforward Mar...

We introduce and investigate an operation with strings suggested by DNA processing (by means of exonucleases): the operation of cutting strings of equal length from the beginning and the end of a string. A related operation is that of cutting a square of a string from the preex of a string. The closure properties of families in the Chomsky hierarchy are investigated (and, with one exception, fo...

Design for disassembly (DfD) approaches play a vital role in (re)designing products from improving their sustainability and circularity performance. This is particularly true the case of complex resource-intensive wherein material recovery reutilization at end-of-life (EoL) dictated by ease-of-disassembly. Various DfD have been developed increasing valuable materials reducing overall time (DT)....

  Abstract   Background: Iatrogenic airway injury after endotracheal intubation and tracheotomy   remains a serious clinical problem. In this study we reviewed post-intubation and traumatic tracheal stenosis in 47 patients with a special attention to the cause, hense surgical treatment of the stenosis was performed and the results compared with the literatures.   Methods: Since February 1995 th...

Optimization of cutting parameters is valuable in terms of providing high precision and efficient machining. One of the effects of cutting force in the end milling operation with low diameter tool (during metal cutting) is tool deflection. Assuming that machining errors mostly arise from tool deflection, attempt was made to optimize machining parameters using Genetic Algorithm (GA) so as to min...

In this Data in Brief paper, a central composite experimental design was planned to collect the surface roughness of an end milling operation of AISI 1045 steel. The surface roughness values are supposed to suffer some kind of variation due to the action of several factors. The main objective here was to present a multivariate experimental design and data collection including control factors, n...

When a conscientious surgeon hears a description of a radical surgical procedure he asks himself: what have been the long term results obtained from the operation recommended? What are the indications and technical difficulties of such a procedure, and what precautions have been pointed out by the author in the technique and after-care? The surgical technique of most orthopaedic operations is n...

Parallel Cellular Automata (PCA) previously has been employed for optimizing bi-objective reservoir operation, where one release is used to meet both objectives. However, if a single release can only be used for one objective, meaning two separate sets of releases are needed, the method is not applicable anymore. In this paper, Multi-Step Parallel Cellular Automata (MSPCA) has been developed fo...
