The stochastic air traffic flow management rerouting problem
We formulate a model for planning the rerouting of aircraft to alleviate en-route congestion, with system capacity being modeled stochastically. To overcome problems with tractability, we apply a Dantzig-Wolfe decomposition and present an efficient method for solving it. The decomposed formulation …

Rerouting Pre-Existing Host Vaccine-Induced Immunity to wards Breast Cancer
<p>For decades, investigators have attempted to activate the immune system to prevent cancer metastasis or recurrence; however, owing to host immune tolerance to cancer antigens and the immunosuppressive environment at tumor sites, many such attempts have failed. The recent success of anti-CTLA4, …

Observations of aircraft proximity to weather for use in rerouting decision aids
Information about pilot behavior in the presence of weather is needed if a decision aid is to be created to assist with enroute replanning. Specifically it is important to know how close pilots are willing to fly to various levels of precipitation. Two surveys and an analytical study were conducted …

Slot-Exchange Mechanisms and Weather-Based Rerouting within an Airspace Planning and Collaborative Decision-Making Model
… Management System (FMS) as well as to provide rerouting strategies. The second major concept concerns modeling the mediated bartering of slot exchanges involving airline trade offers for arrival/departure slots at an arrival airport that is affected by the Ground Delay Program (GDP), while …

Data-driven flight path rerouting during adverse weather: Design and development of a passenger-centric model and framework for alternative flight path generation using nature inspired techniques
… fuel burn costs. A genetic algorithm (GA)-based rerouting technique that generates optimised alternative flight paths was proposed. The technique used a modified mutation strategy to improve global search. A discrete firefly algorithm-based rerouting method was also developed to improve rerouting …

Dynamic probabilistic network protection in large-scale failure scenarios
… The proposed preventive model is able to adjust rerouting decision parameters in a dynamic way by considering the disaster expansion and available network resources at each decision interval. Our findings show that the proposed preventive protection model significantly reduces the average number …

Truck Activity Pattern Classification Using Anonymous Mobile Sensor Data
… of a spatio-temporal regression model to capture rerouting behavior of trucks. </p> <p>First, we developed a K-means unsupervised clustering algorithm to find unique and representative daily activity patterns from GPS data. For a statewide GPS data sample, we are able to reduce over 300,000 daily …

The Effect of Airport Delays on the Evolution of the U.S. Air Travel Network
… are studied: increasing aircraft size, rerouting transit passengers, and decreasing schedule peaking. Regression analysis is used to determine where significant relationships exist between study variables and the overall level of flight delay for all airlines at each airport they serve. …

Self-stabilizing wormhole routing in hypercubes
… changes. We propose an efficient scheme of rerouting flits in case of node/link failures. Similar to the first algorithm, this algorithm also tries to follow preferred dimensions if they are nonfaulty at the time of transmitting the flits. However, due to topological faults it is necessary …

Autonomy Work: Personhood, Expertise, and Activism of Disabled AI Data Workers in China
… in and around technology. I call this mechanism “rerouting.” Instead of a complete departure from asymmetrical power relations, my interlocutors “reroute” the pathways between different human and non-human nodes without changing the nodes per se. They do so within the sociotechnical systems they …

Optical sensing as a means of monitoring health of multicomputer networks
… strain. This detection method allows the rerouting of critical data before data link failure occurs. This thesis investigates the implementation of the extrinsic Fabry-Perot interferometer into an optical hybrid communications/sensing network. A testbed of personal computers, acting as …

Minimizing average handling time in contact centers by introducing a new process: Rowan Support Desk case study
… research will show that with minimal effort in rerouting the unsolved tickets, we can decrease average handling time which simultaneously increases the total number of resolved tickets and minimize total processing time.

Traffic flow management under emergency conditions in and around the Virginia Tidewater area tunnels
… network. Traffic management actions like rerouting policies could be implemented and thus alleviate the problem. MASSVAC2, a computer simulation model for mass evacuation under emergency conditions was employed for analyzing different traffic management scenarios.

Handling Multiple Failures in IP Networks
… been several recent proposals based on local rerouting to provide greater network availability despite failures. While most of these proposals are effective in handling single failures, they can cause either loops or dropped packets in the case of multiple independent failures. This …

Application of data fusion and machine learning to the analysis of the relevancy of recommended flight reroutes
… in the National Airspace System. Indeed, rerouting flights ensures that aircraft comply with the air traffic flow, remain away from special use airspace, and avoid saturated areas of the airspace and areas of inclement weather. Reroute advisories are defined by their level of urgency i.e. …

A Sense of Time, A Sense of Self: The 'Lived Perspective' of the Walk
… and an aging infrastructure may lead to the rerouting of the CSX Railway south of Washington, D.C., shutting down the existing line, I propose to convert the CSX Railway bridge that crosses the Anacostia River in Southeast Washington to an open public space. While other portions of the track …

Metaheuristic algorithms for air-route optimization under climate change
… dominant corridor versus when it induces genuine rerouting (e.g., hub switches). On a 20×20 grid, ACO matches the Dijkstra optimum on the additive baseline with higher compute cost; when turbulence is active, a modest colony may under-explore, which we quantify and remedy by tuning. On a toy …
