Abstract Background Objective measurement of movement asymmetry is gaining in popularity, especially as an adjunct to traditional lameness evaluation. Earlier research has highlighted the need for more knowledge regarding the clinical significance of measured movement asymmetry, and the influence of biological variation. Evaluating the locomotor system of the Standardbred trotter can be challenging, and studies using objective technology on this breed are few. The aim of this study was to quantify the prevalence and magnitude of objectively measured movement asymmetry in young, presumed sound Standardbred trotters, by performing objective movement analysis during in-hand trot and while driven on a track. Our hypothesis was that asymmetry scores would be higher when evaluating horses in-hand versus while driving on a track.Results Of 103 horses included in the study, 77 were measured both in-hand and on the track, 24 were measured only in-hand, and two were measured only on the track. Previously set symmetry thresholds for the measurement system were used, during both in-hand and track trials. The majority of horses (91, 88.3%) did not have any trials below threshold. Front and/or hind limb parameters were above the symmetry thresholds during in-hand trials for 94 (93.1%) horses, and during track trials for 74 (93.7%) horses. For the total 180 in-hand and track trials, 166 (92.2%) trials were above threshold. Asymmetry magnitude ranged from mild to severe, with the majority of horses showing mild asymmetry. A minority of horses (19.7%) switched side of asymmetry for one or more parameters between in-hand and track trials. Trial standard deviations were overall high, mainly due to horse behavior, and this variability should be considered when interpreting the results. There was no significant effect on asymmetry of measuring horses in-hand versus driven.Conclusions A high proportion of presumed sound Standardbred yearlings showed movement asymmetries above previously determined thresholds. The biological and clinical relevance of the study findings may be aided by examining how this asymmetry evolves over time and with training. This is important in order to ensure the welfare of the Standardbred trotter.

Computer Based

Better methods are needed to evaluate the therapy of diseases which are subject to frequent fluctuation in the intensity of symptoms and lack an objective measurement reflecting the disease state. A patient diary system is reported in which patient symptomatology is collected and the data computerized. The system provides for management and automated tabulation of large volumes of data. It has proved to be a successful way to obtain the detailed symptomatology data necessary to assess therapeutic regimens in hay fever clinical studies.

Automated Determination

Based on laboratory trials on the optimal flocculating point, in which the variation of this command variable of the juice purification was demonstrated, a prototype for the automated determination was constructed. A measurement system, which is operated in the bypass of the industrial production, is used for an automatic stepwise carbonatation of main liming juice. Starting at pH = 11.2 carbonatation gas is injected to bring down the pH to 10.4 in 0.1 or 0.2 pH units per step. After every pH step, the sedimentation behavior of the juice is characterized by means of a turbidity measurement after a clarification time of 3.5 min. With the function of turbidity versus pH value the optimal end point of the1st carbonatation can be determined. All in all an analysis takes approximately 60 min. Afterwards, an automated cleaning step takes place. For the prototype, the control of every step as well as the interpretation of the results is carried out with a personal computer. Based on the good experiences a so-called industrial version of this measurement system was constructed.

High Voltage System

This paper describes the structure and the principle of the NI DAQ based measurement system used for investigating the frequency dependent behavior of instrument transformers in the high voltage system. A computer based NI DAQ card is utilized as the data acquisition system in the new measurement system. The software digital filter and the phase locked loop are implemented to obtain the magnitude and phase angle, respectively. With this measurement system, we investigated frequency responses of several voltage and current transformers at the converter station of the Germany railway.
