Bottleneck Merge Control Strategies for Work Zones: Available Options and Current Practices

Synthesis of Unconventional Dynamic Merge Metering Traffic Control for Work Zones

This paper presents an unconventional approach for work-zone bottleneck traffic control through integrating the dynamic late merge with a merge metering via wireless communication at the downstream taper area of a work zone, termed as Dynamic Merge Metering Traffic Control System (DMM-Tracs). The architecture and communication system for the DMM-Tracs, including system components, communication...

An Analysis of Merge Strategies for Merge-and-Shrink Heuristics

The merge-and-shrink framework provides a general basis for the computation of abstraction heuristics for factored transition systems. Recent experimental and theoretical research demonstrated the utility of non-linear merge strategies, which have not been studied in depth. We experimentally analyze the quality of state-of-the-art merge strategies by comparing them to random strategies and with...

Strategies for Stable Merge Sorting

We introduce new stable, natural merge sort algorithms, called 2-merge sort and α-merge sort. We prove upper and lower bounds for several merge sort algorithms, including Timsort, Shiver’s sort, α-stack sorts, and our new 2-merge and α-merge sorts. The upper and lower bounds have the forms c · n logm and c · n logn for inputs of length n comprising m runs. For Timsort, we prove a lower bound of...

Current strategies for pain control.

Pain is the most feared symptom for patients diagnosed with cancer. Although our understanding of cancer pain and its management has greatly improved in the past decade, an unacceptably large proportion of patients still do not receive adequate pain relief. Before commencing any form of treatment, patients must receive a thorough assessment in order to define the pain, causes and severity. The ...
