Abstract. The analysis utilized data on performance traits recorded between 1993 and 2004 on 3- and 4-year-old Hungarian Sporthorse mares. Traits were categorized in three groups, chosen to describe conformation, free jumping and movement. Low to moderate correlations were found among traits within each of those groups. There were high correlations between type and frame for both ages; and within free jumping performance traits, jumping style and jumping ability were highly correlated as well. In principal component analyses of test results for 3- and 4-year-old mares, 9 factors (ratio of variance = 80.935) and 7 factors (ratio of variance = 74.115) were identified, respectively. Dendograms based upon cluster analysis verified the separation of trait groups. The trait of "impulsion in elasticity of movement" could be assigned to movement traits in 3-year-old; but as a probable consequence of training, it could be assigned to conformation traits, especially to overall impression, when horses were 4-year-old.

Analysis Of Performance

This study conducted a vibration table excitation test in order to evaluate performance of a tuned liquid damper (TLD), which was installed for vibration attenuation in a high-rise building, according to its installation direction. The TLD's base shear force and wave height characteristics changed according to excitation direction. When the excitation direction of the TLD was lower than 45 degrees, base shear force and wave height were the same as excitation direction at zero degree. However, when the excitation direction was 45 degrees or higher, base shear force and wave height were affected by excitation amplitude at 5mm or larger.

Analysis Of Performance

The Old-Kladruby horse is the only autochthonous Czech horse, a gene pool and national cultural heritage, which has been bred continually for more than 400 years in the Czech Lands. During such a long time span it has become perfectly adapted to a specific environment. The performance test is one of the most important factors, which decides whether the horse is to be incorporated in breeding and it is also a basis for efficiency testing. In our project we focused on a detailed analysis of performance tests of this breed with the aim to streamline the system of evaluation, above all in terms of increasing its objectivity.Our database records and evaluates the results of a performance tests of the Old-Kladruby horses from the beginning of keeping records in the National Stud Farm Kladruby nad Labem. The comparisons of horses were based on the colour variant, foundation stock, family, sex, owner and year of performance test. Apart from this we observed the correlations among the particular characters and features evaluated in the performance test. We also compared the systems of performance tests of the Old-Kladruby and Lipican horses.

Variation Simulation

A method of wheel load variation simulation for automobile ABS performance test bench is presented in the paper. To simulate the wheel load variation of the detected vehicle, the wheel placement angle on the rollers can be changed by adjusting the wheelbase between the ABS performance test bench’s two rollers, which support the same wheel. Equivalent wheel load is defined to reflect wheel load variation simulation, and the relationship among the equivalent wheel load, roller adhesion coefficient and wheel placement angle is also be analyzed. The simulation results show that the equivalent wheel load is not only can greater than wheel load many times, but also can less than wheel load. The minimum equivalent wheel load is determined by the critical wheel placement angle.

Analysis Of Performance

This study involves the design and fabrication of a Wood Plastic Composite (WPC) extruding machine that recycle wood and plastic wastes; sawdust (SD) and polyethylene terephthalate (PET) into useful products for interior and exterior building applications. The machine was designed using locally sourced raw materials making it affordable, user friendly and can easily be maintained. The major components of the machine include; the melting and mixing chamber, extruding unit, heaters, control panel and discharged unit. PET chips were melted and mixed with SD at temperature 190 0C inside the melting chamber before feeding the extruding unit for thorough kneading. The extrudate is collected into a shaped mould, hot compressed and allowed to cool down before removal. A 4hp 3-phase electric motor was the prime mover. Analysis of performance test carried out on the extruder using three screw speed of 222 rpm, 277 rpm and 370 rpm shows that the best WPC was produced at speed 277 rpm with machine recycling efficiency of 89 %. It took 13 minutes to recycle a batch of the waste materials with a throughput of 0.8 kg/hr and specific mechanical energy of 145 kJ/kg. This machine gives effective waste management by turning it to wealth.
