A framework for fast handoff schemes in wireless ATM networks
In this research, we focus on providing a framework that extends the fixed ATM standard to support user mobility in future WATM networks. The WATM architecture allows for the migration of fixed ATM networks without major modifications. Thus most of the mobility functions are implemented on the …

Predictive modeling of fuel efficiency of trucks
<p>This research studied the behavior of several controllable variables that affect the fuel efficiency of trucks. Re-routing is the process of modifying the parameters of the routes for a set of trips to optimize fuel consumption and also to increase customer satisfaction through efficient …

Routing and scheduling models for robust allocation of slack
… conventional scheduling models, however, ignore the presence of uncertainties in actual operations in order to limit the complexity of the problem. This leads to schedules that are prone to delays and disruptions. As a result, there has been wide interest recently in building robustness into …

Evaluating Fuel-Climate Tradeoffs in Contrail Avoidance
… Operational contrail avoidance via flight re-routing may be an effective and efficient mitigation approach due to the geometry of contrail-forming regions. Contrail avoidance strategies will result in fuel burn penalties and, consequently, additional climate warming from carbon dioxide …

Intrinsic constraints on cross-modal plasticity
… decades numerous examples have demonstrated the remarkable plasticity of the developing brain. This plasticity occurs from the level of a single synapse to the repatterning of sensory input. One paradigm that demonstrates this plasticity is the re-routing of sensory input to inappropriate …

A comparative analysis of denial of service vulnerabilities in network protocols
As global reliance on the Internet continues to grow, Denial of Service [DoS] attacks pose an ever greater threat to society. In recent years the proliferation of poorly secured "Internet of Things" [IoT] devices has enabled attackers to build massive botnets which have delivered on this threat …

A Comparison of the Army Corps of Engineers Hydrologic Modeling System and Autodesk Storm and Sanitary Analysis for Hydraulic and Hydrologic Analysis and Design
… of impervious surfaces to once pervious land and re-routing open channels and flow paths can cause flooding or declining water levels within a watershed. Many studies of these issues have found that there can be multiple factors causing hydrological and hydraulic impacts, and it can be hard to …

Survivability Analysis of Two Specific 16-Node, 24-Link Communication Networks
… topology 1 and 2, under usual network failures. The survivability of the networks mainly comes from their structure. Both topologies have different routes between all source-destination pairs, which gives the networks high route diversity. In fact, both topologies considered are regular …

Controls on long-term drainage development of the Carboneras Basin, SE Spain
… evolution can play an important role in the research on global changes. For longer term controls such as tectonics and climate this necessitates the use of a long time-scale such as the Plio/Pleistocene, and the integration of both geological and geomorphological data. This thesis uses data …

Analysis and Optimization of Chassis Movements in Transportation Networks with Centralized Chassis Processing Facilities
… impact on port drayage efficiency. The concept revolves around an off-dock terminal (or several off-dock terminals), referred to as Chassis Processing Facilities (CPFs). A CPF is located close to the port, where trucks will go to exchange chassis, thereby reducing traffic at the marine terminals …

An Airspace Planning and Collaborative Decision Making Model Under Safety, Workload, and Equity Considerations
… Federal Aviation Administration (FAA)-sponsored effort to increase U.S. National Airspace (NAS) capacity by 30 percent. Given a set of flights that must be scheduled during some planning horizon, we use a mixed-integer programming formulation to select a set of flight plans from among …

Multi-impairment and multi-channel optical performance monitoring
… networks will evolve from static to dynamically reconfigurable architectures to meet the increasing bandwidth and service requirements. The benefits of dynamically reconfigurable networks (improved operations, reduced footprint and cost) have introduced new challenges, in particular the need for …

Increasing the robustness of networked systems
What popular news do you recall about networked systems? You've probably heard about the several hour failure at Amazon's computing utility that knocked down many startups for several hours, or the attacks that forced the Estonian government web-sites to be inaccessible for several days, or you may …
