- Static timing analyzers, which are used to analyze real-time systems, need to know the minimum and maximum number of iterations associated with each loop in a real-time program so accurate timing predictions can be obtained. This paper describes three com

- BackgroundDuring orthopaedic assessment of lame horses, a head nod is commonly present in both primary forelimb and hindlimb lame horses. Additional motion metrics that could assist clinicians in correctly differentiating between these two scenarios would be of great clinical value. ObjectivesThe primary objective of this study was to examine whether withers movement asymmetry can be used in a clinical setting to distinguish primary forelimb lameness from compensatory head movement asymmetry due to primary hindlimb lameness. Study designRetrospective, multicentre study. MethodsMovement asymmetry of head, withers and pelvis was measured using multi-camera optical motion capture, as part of routine lameness investigations at four European equine hospitals. Vertical movement asymmetry parameters from 317 horses trotting in a straight line were compared before and after successful diagnostic analgesia of a single limb. Descriptive statistics, t-tests and linear models were used to analyse the data. ResultsIn forelimb lame horses, 80%-81% showed head and withers asymmetry both indicating lameness in the same forelimb. In hindlimb lame horses, 69%-72% showed head asymmetry ipsilateral to the lame hindlimb and withers asymmetry diagonal to the lame hindlimb, thus, head and withers asymmetry indicated lameness in different forelimbs. A large (>15 mm) compensatory head nod was seen in 28%-31% of the hindlimb lame horses. In 89%-92% of these, head and withers asymmetry indicated lameness in different forelimbs. Withers asymmetry decreased linearly with reduced head or pelvic asymmetry for both forelimb and hindlimb lame horses. Main limitationsCompensatory strategies were evaluated on group level to identify common patterns, potentially ignoring uncommon individual strategies. ConclusionsWithers vertical movement asymmetry metrics can be useful in helping to locate the primary lame limb during quantitative lameness assessment. Head and withers movement asymmetry parameters generally indicate the same forelimb in forelimb lame horses, but different forelimbs in hindlimb lame horses.

- Self-healing is a promising approach for designing reliable digital systems. It refers to the ability of a system to detect faults and automatically fixing them to avoid total failure. With the development of digital systems, heterogeneous systems, in which some parts of the system are executed on the programmable logic, and some other parts run on the processing elements (CPU), are becoming more prevalent. In this work, we propose an adjustable self-healing method that is applicable to heterogeneous systems with accelerated functions and enables the designers to add the self-healing feature to the design. In this method, by manipulating the software codes that are being executed on the processing element, we add the ability to verify the accelerated functions on the programmable logic and heal the possible failures to the system. This is done not only in a straightforward manner but also without being forced to choose a specific reliability-overhead point. The designer will have the option to select the optimum configuration for a desired reliability level. Experimental results on a large design including several accelerated functions are provided and show 42% improvement of reliability by having 27% overhead, as an example of the reliability-overhead point.
