Teaching with the advanced placement GridWorld case study: conference workshop

Journal of computing sciences in colleges (2009)

Laurie White Robert Allen

Case studies expose students to large programs, enabling them to understand the importance of design and good programming style while encouraging teamwork and active learning. The AP Computer Science curriculum has used case studies since 1995. Beginning in 2008, the APCS curriculum includes the GridWorld Case Study. The first portion of the workshop will introduce the participants to the GridWorld environment allowing them to explore GridWorld through a series of guided activities which demonstrate inheritance and class interaction. During the second portion of the workshop participants will be shown examples of how GridWorld can be used in a typical CS-1 course.

Optimizing the acquisition time of the middle latency response using maximum length sequences and chirps

The Journal of the Acoustical Society of America (2002)

Steven L. Bell Robert Allen Mark E. Lutman

The middle latency response (MLR) may be used as an indicator of anesthetic depth but has been criticized due to its long acquisition time. This study explores methods for optimizing recording of the MLR to maximize signal-to-noise ratio (SNR) and hence reduce acquisition time. The first experiment investigates the effects of increasing stimulation rate beyond conventional values and also using higher rates by means of maximum length sequences (MLS). The second experiment compares the use of click and chirp stimuli to elicit the MLR, both at conventional and MLS stimulation rates. For all conditions total recording duration is fixed at 185 s and stimulation level is fixed at 60 dB SL. It was found that SNR increases progressively with rate using conventional click stimulation until the theoretical rate limit is reached at the reciprocal of the response duration. The SNR improvement is equivalent to increasing test speed by a factor of 3. Using MLS stimulation, the SNR increases further until a maximum is reached at a rate of 167 clicks/s, equivalent to a fivefold test speed improvement relative to a conventional recording at 5 clicks/s. The use of chirp stimuli designed to compensate for the frequency dependent cochlear traveling wave delay produces an increase in wave V–Na amplitude at all recording rates. For the later latency waves of the response an increase in amplitude is seen for MLS, but not for conventional chirp trains. The optimum SNR was obtained using chirp stimuli at a MLS rate of 167 opportunities/s. It is concluded that the combination of chirps and MLS can reduce acquisition time to less than one-tenth of that required for conventional stimulation at 5 clicks/s for the same SNR. This would confer material benefits for estimating anesthetic depth using MLR.

Hand and arm injuries associated with repetitive manual work in industry: a review of disorders, risk factors and preventive measures

Ergonomics (1999)

J.M. Muggleton Robert Allen P.H. Chappell

Musculoskeletal disorders are the most common self-reported, work-related illness in the UK, with upper limb disorders ranking second only to back complaints. The rapid increase in disablement cases, the reduced productivity resulting from the disorders, and, perhaps, the threat of litigation which is on the increase, has led to an increased awareness of the problems and an increasing desire to reduce the incidence of such disorders. This paper reviews the problem of upper limb disorders and focuses on those disorders that could be associated with repetitive manual work in industry. The disorders are described and categorized, and potential occupational risk factors are discussed and related to the injuries. In addition, a number of preventive measures, in the form of ergonomics design changes and changes in workplace practice are reviewed. There are frequent calls for well-designed epidemiological studies, so that meaningful dose-response relationships can be drawn up. A significnat part of good study design is associated with measurement and analysis of the user-tool interface and the working environment. With this in mind, a variety of measurement techniques are described. Furthermore, this paper highlights the need for study designs to be founded on a better understanding of the potential damage mechanisms, and points the way towards which areas should be investigated.

Spine kinematic analysis using digital videofluoroscopy and image processing

Robert Allen C. Simonis Alan Breen

The author has examined spine kinematics using videofluoroscopy imaging combined with digital image processing. The parameters studied were instantaneous centres of rotation, intervertebral angles, angles of rotation and displacement for each vertebral joint. Parallel computation, using an array of transputers, was used. The method can be used to produce an efficient display to aid clinical diagnosis. >
