For time-constrained applications, repair-server-based active local recovery approaches can be valuable in providing low-latency reliable multicast service. However, an active multicast repair service consumes resources at the repair servers in the multicast tree. A scheme was thus presented in [10] to dynamically activate/deactivate repair servers with the goal of using as few system resources...

Condition-Based Maintenance (CBM) optimization using Proportional Hazards Model (PHM) is a kind of maintenance optimization problem in which inspections of a system relevant to its failure rate depending on the age and value of covariates are performed in time intervals. The general approach for constructing a CBM based on PHM for a system is to minimize a long run average cost per unit of time...

The failure and repair of modules in an N-Modular Redundant (NMR) system are governed by a failure time distribution and repair time distribution, respectively. It is generally reasonable to assume that a module’s failure time distribution is a simple exponential distribution. However, it is not reasonable to assume that the repair time distribution is also exponential. Reliability models with ...

The design of new electrically debondable adhesives has been an area enormous interest for the recycling, repair, and reuse electrical components last decade. However, complexity analyzing debonding process under real conditions is a major obstacle elucidating mechanism. Here, general mechanism ionic acrylic based on imidazolium liquids reported. Using synchrotron-based characterization techniq...

objective(s): coronary artery disease (cad) is the leading cause of death in both male and female worldwide. the main cause of cad is the atherosclerosis of coronary arteries, which is, mostly caused by genetic alteration. 50% of such cases occur in mitotic cells where single-strand breaks occur spontaneously or due to ionizing radiation. x-ray repair cross-complementing protein 1 (xrcc1) as a ...

There has been worldwide concern for sustainable development especially after the 1992’s Rio’s UN Conference on Environment and Development. Rapid encroachment of urban development on valuable agricultural land will have great in ̄ uence on whether sustainable development can be achieved. A sustainable land development model is developed using GIS in an attempt to control urban sprawl under rapi...
