Lyme Disease: An Influential Outdoor Hazard, Kevin Kang

Dartmouth Undergraduate Journal of Science

Lyme disease is an important, common illness in New England. A relatively new illness, it was discovered about forty years ago in the town of Lyme, Connecticut. Now, it has become the most common vector-transmitted illness in the United States, with over 30,000 cases annually. Lyme disease arises when a bacterium is transmitted to a human via deer tick bite, so those of us involved in outdoor sports are most likely to contract the disease. Inhabitants of New England and the northeastern U.S. are most vulnerable to the disease, as 95% of Lyme Disease cases occur in only 14 out …

A Multiagent-Based Approach For Vehicle Routing By Considering Both Arriving On Time And Total Travel Time, Zhiguang Cao, Hongliang Guo, Jie Zhang

Research Collection School Of Computing and Information Systems

Arriving on time and total travel time are two important properties for vehicle routing. Existing route guidance approaches always consider them independently, because they may conflict with each other. In this article, we develop a semi-decentralized multiagent-based vehicle routing approach where vehicle agents follow the local route guidance by infrastructure agents at each intersection, and infrastructure agents perform the route guidance by solving a route assignment problem. It integrates the two properties by expressing them as two objective terms of the route assignment problem. Regarding arriving on time, it is formulated based on the probability tail model, which aims to …

Efficient Gate System Operations For A Multipurpose Port Using Simulation Optimization, Ketki Kulkarni, Trong Khiem Tran, Hai Wang, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

Port capacity is determined by three major infrastructural resources namely, berths, yards and gates. Theadvertised capacity is constrained by the least of the capacities of the three resources. While a lot ofattention has been paid to optimizing berth and yard capacities, not much attention has been given toanalyzing the gate capacity. The gates are a key node between the land-side and sea-side operations in anocean-to-cities value chain. The gate system under consideration, located at an important port in an Asiancity, is a multi-class parallel queuing system with non-homogeneous Poisson arrivals.

E2district: Behaviour Demand Response, Julia Blanke, Christian Beder, Emily Twomey, Sezen Aladag Ozdemir, Martin Klepal

NIMBUS Articles

This work describes the Behaviour Demand Response approach proposed in the context of the EU Horizon 2020 E2District project, which aims at achieving energy efficiency in District Heating and Cooling (DHC) systems applied in building blocks. Behaviour Demand Response (BDR) can be understood as the attempt to adjust the demand for power in accordance with supply side constraints, instead of adjusting the supply side alone without considering the potential flexibility of the demand. In contrast to this, typical current energy systems assume a rather strict distinction between a consumer driven demand side behaviour on one end and a matching supply …
