Nature Ecology & Evolution, 2017
Across land, air and water, larger animals are generally faster, but only up to a certain point. A new study provides a unifying explanation for why this might be so.

Journal of Theoretical Biology, 1995
An upper bound on the speed of evolution is derived. The bound concerns the amount of genetic information which is expressed in observable ways in various aspects of the phenotype. The genetic information expressed in some part of the phenotype of a species cannot increase faster than a given rate, determined by the selection pressure on that part ...

Are There Speed Limits in Rehabilitation?
Journal of Orthopaedic & Sports Physical Therapy, 2005During the course of rehabilitation of a patient, I often wonder if there are speed limits to our rehabilitation program. This dilemma usually occurs when a patient is recovering exceedingly fast, making me wonder if we are progressing too quickly and violating the soft tissue healing constraints. In the specific case of patients who have undergone ACL

Engine speed limiter for watercrafts
IEEE Transactions on Control Systems Technology, 2006Engine speed limiters are safety devices designed to prevent an engine from exceeding a predetermined high speed. The speed limiter herewith presented is designed for large and sudden load variations which require accurate and fast air-fuel ratio control. It is based on feedback linearization and online estimation of the load torque.

Nowadays, there is no exact method for determining the optimal speed limit in winter and the problems associated with winter speed limit has not yet been addressed in Hokkaido. Therefore, this study aims at determining the optimal winter speed limit through the application of a cost analysis and by analysis of effects of road and traffic conditions ...

Exploring the speed limit of SM2
2014 IEEE 3rd International Conference on Cloud Computing and Intelligence Systems, 2014In this paper, we explore the serial and parallel point multiplication speed limit of SM2 public key cryptographic algorithm. The optimization criteria for our design is speed, we carry out a thorough analysis on SM2 point multiplication structure and summarize three main factors that contributes to the ultra high-speed realization of point ...

Recognition of speed limits on speed-limit signs by using machine learning
2017 24th International Conference on Mechatronics and Machine Vision in Practice (M2VIP), 2017This study describes a method for using a camera to automatically recognize the speed limits on speed-limit signs. This method consists of the following three processes: first (1) a method of detecting the speed-limit signs with a machine learning method utilizing the local binary pattern (LBP) feature quantities as information helpful for ...

Seasonally Changing Speed Limits: Effects on Speeds and Accidents
Transportation Research Record: Journal of the Transportation Research Board, 2000Summarized are the results of studies that examined the effects of speed limits that were changed on a seasonal basis on Finnish main roads. The first of these studies was an experimental study (1987–1989) in which speed limits were changed according to time of year.
