Drilling engineering comprises a major part of production and exploration in oil fields and drilling risk is a significant ingredient to success. As one of the crucial ways to terminate oil spill event, relief well assumes great responsibility. Thus it is essential to analyze and assess the risk of relief well technique before drilling operation in order to guarantee rescue project work smoothl...

Due to the inappropriate or untimely distribution of post-disaster goods, many regions did not receive timely and efficient relief for infected people in coronavirus disease outbreak that began 2019. This study develops a model emergency routing problem (ERRP) distribute more reasonably. Unlike general route optimizations, patients’ suffering is taken into account model, allowing patients urgen...

Context: In Wireless Networks, MANETs can dynamically create a network without relying on central hub or infrastructure. These features will be helpful for scenarios such as disaster relief military operations. However, the absence of authority presents challenges concerning security and routing, affecting network's stability capabilities. Approach: A proposed scheme incorporates consideration ...

We propose a novel design method that incorporates multiple-layer relief profiles of diffractive phase elements to implement integrated operations on the incident beams according to their wavelengths. We demonstrate simultaneous wavelength-division demultiplexing, arbitrary (even random) wavelength shuffling or routing, spatial focusing, and other manipulations of multiwavelength beams, such as...

Prompt reactions to the vital emergency relief necessities right after sudden-onset disasters, which are included distribution and victim evacuation, crucial mitigation of disaster influences in concerned regions. This paper renders a bi-objective optimization model plan humanitarian districted logistics network, broad range simultaneous decisions concerning facility location-allocation, redist...

one of the most important measures needed to be done in times of crisis is to optimize the allocation and distribution of resources among individuals. time is a critical factor effective to increase the number of people rescued by the relief activities.in this paper, we present a relief vehicle routing model in the affected area which uses covering tour approach to reduce total response time. a...
