Speed Optimization vs Speed Reduction: the Speed Limit Debate [PDF]

, 2019
The purpose of this paper is to shed some light into the speed limit debate, and specifically whether reducing speed by imposing a speed limit is better than doing the same by imposing a bunker levy. This debate, along with the various issues of speed optimization versus speed reduction, is currently ongoing at the International Maritime Organization ...

Vehicle Speed Reduction Based on Authorized Speed Limits

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Keeping vehicle speed under control according to the speed limit is considered the main key to the traffic departments in the world to reduce vehicle accidents. This paper presents a prototype of a novel idea to control vehicle speed automatically according to the types of roads that the vehicle passes through without human ...

Real-Time Idle Time Cancellation by Means of Miniterm 4.0

Energies, 2019
The paper presents how single-model robotized manufacturing lines are rebalanced to save energy. The key idea is to eliminate idle time that each robot has by means of adjusting the velocity.

A semi-empirical operational performance prediction for anchor handling tug supply (AHTS) vessel [PDF]

BIO Web of Conferences
Speed reduction is a practice way for the ship operator to increase efficiency and reduce Green House Gas (GHG) emission in the shipping industry. In this paper, using Kwon’s method to predict the added resistance caused by wave and wind for specific ...

Speed reductions, inequalities, and transport [PDF]

Injury Prevention, 2001
Editor,—We read the editorials in the BMJ and Injury Prevention about speed limits with interest1, 2 and would like to share some of the Scottish experience on speed reduction. Councils throughout Scotland are conducting trials of advisory 20 mph limits as part of a Scottish Executive initiative. In Lothian these are generally in residential areas and

Understanding temporal rhythms and travel behaviour at destinations: Potential ways to achieve more sustainable travel [PDF]

, 2013
This paper analyses the roles played by time in destination-based travel behaviour. It contrasts clock time's linear view of time with fragmented time, instantaneous time, fluid time and flow, time out and the multiple temporalities of tourism ...

En-route speed reduction for the mangement of ATFM delays [PDF]

, 2009
In this paper a new concept aimed at better dealing with delays caused by regulations is presented. Inspired in future 4D trajectories, where a time constraint can be applied at each way-point, it is proposed to spread the total delay imposed by a ...

Speeding Multicast by Acknowledgment Reduction Technique (SMART) [PDF]

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
We present a novel feedback protocol for wireless broadcast networks that utilize linear network coding. We consider transmission of packets from one source to many receivers over a single-hop broadcast erasure channel. Our method utilizes a predictive model to request feedback only when the probability that all receivers have completed decoding is ...
