History Of The Wall Creek Wildlife Management Area

As the manager for the Wall Creek Wildlife Management Area for 34 years, I will provide an overview of the history of the FWP purchase of the Wall Creek WMA as well as an overview of the history of the grazing system and elk and livestock use of the game range

Modifying Koha to Use as a Local Authors\u27 Catalog

Koha is a widely-used Integrated Library System, free to download, free to use. It is open-source software, is infinitely configurable and can be used in a variety of ways. This presentation will show how MedStar Washington Hospital Center is using Koha and modified Medline records to track articles written by MedStar authors

Smoller and King: California Should Have its Own Solar Decathlon

While the Federal Government has pulled back on the reins, California is vigorously going green. California’s legislature has passed ambitious climate change legislation while governors of both parties have made tackling climate change a priority. Last month, the City of Los Angeles released its own ambitious Green New Deal. To increase its impact, the California competition could be expanded to include a sustainability exposition which would include professional development and consumer workshops, as well as K-12 education events. Sustainability vendors would display and explain their products, services and new technologies. As many as 100,000 visitors per day could visit the competition houses as well as the exposition

THE AGRICULTURAL RISK MANAGEMENT SIMULATOR MICROCOMPUTER PROGRAM

The Agricultural Risk Management Simulator (ARMS) is a microcomputer program designed to help users evaluate strategies for managing yield and price risk in crop farming operations. Risk management strategies are defined by choices regarding crop mix, the purchase of multiple peril crop insurance, and the use of forward contracting. Probabilistic budgeting is used to determine the net cash flow probability distribution for each strategy considered. Flexibility with regard to both sources of probabilistic information and the form of yield and price probability distributions is a noteworthy feature of the program.Risk and Uncertainty,

A method for synchronising digitised video data

This paper presents a general method for synchronising digitised video data using a mathematical approach based upon the direct linear transformation reconstruction technique. The method was tested using digitised data from genlocked video recordings of gymnastic vaulting, tumbling, high bar and rings. The mean synchronisation error was less than 0.002 s for vaulting and less than 0.001 s for the other activities

Determining subject specific torque parameters for use in a torque driven simulation model of dynamic jumping

This paper describes a method for defining the maximum torque which can be produced at a joint from isovelocity torque measurements on an individual. The method is applied to an elite male gymnast in order to calculate subject specific joint torque parameters for the knee joint. Isovelocity knee extension torque data were collected for the gymnast using a two repetition concentric-eccentric protocol over a 75◦ range of crank motion at preset crank angular velocities ranging from 20◦s-1 to 250◦s-1. During these isovelocity movements, differences of up to 35◦ were found between the angle of the dynamometer crank and the knee joint angle of the subject. In addition faster preset crank angular velocities gave smaller ranges of isovelocity motion for both the crank and joint. The simulation of an isovelocity movement at a joint angular velocity of 150◦s-1 showed that, for realistic series elastic component extensions, the angular velocity of the joint can be assumed to be the same as the angular velocity of the contractile component during the majority of the isovelocity trial. Fitting an 18 parameter exponential function to experimental isovelocity joint torque / angle / angular velocity data resulted in a surface which was well-behaved over the complete range of angular velocities and within the specified range of joint angles used to calculate the surface

The effect of marker placement around the elbow on calculated elbow extension during bowling in cricket

The elbow extension angle during bowling in cricket may be calculated from the positions of markers attached around the shoulder, elbow and wrist using an automated laboratory-based motion analysis system. The effects of two elbow-marker sets were compared. In the first, a pair of markers was placed medially and laterally close to the condyles while in the second a triad of markers was placed on the back of the upper arm close to the elbow. The root mean square (RMS) difference in elbow extension angle between the two methods at four key instants was 8° for 12 fast bowlers and 4° for 12 spin bowlers. When evaluated against video estimates of the elbow extension angle for the fast bowlers, the elbow extension angle calculated using the pair method had an RMS error of 2° while the triad method had an RMS error of 8°. The corresponding errors for the spin bowlers were 3° and 5°, respectively. It is thought that the greater errors associated with the triad is a consequence of soft tissue movement in this dynamic activity. This is consistent with the finding of greater error for the fast bowlers compared with the spin bowlers

Quantifying elbow extension and elbow hyperextension in cricket bowling: a case study of Jenny Gunn

In this study a method for determining elbow extension and elbow abduction for a cricket bowling delivery was developed and assessed for Jenny Gunn who has hypermobility in both elbows and whose bowling action has been repeatedly queried by umpires. Bowling is a dynamic activity which is assessed visually in real time in a cricket match by an umpire. When the legality of a bowler's action is questioned by an umpire a quantitative analysis is undertaken using a marker based motion analysis system. This method of quantifying elbow extension should agree with a visual assessment of when the arm is "straight'' and should minimise the effects of marker movement. A set of six markers on the bowling arm were used to calculate elbow angles. Differences of up to 1 degrees for elbow extension and up to 2 degrees for elbow abduction were found when angles calculated from the marker set for static straight arm trials were compared with measurements taken by a chartered sports physiotherapist. In addition comparison of elbow extension angles at ball release calculated from the markers during bowling trials with those measured from high speed video also showed good agreement with mean differences of 0 degrees +/- 2 degrees
