The purpose of this study was to compare the postoperative success and stability of two different autografts used to reconstruct the anterior cruciate ligament (ACL): doubled semitendinosus/gracilis (DST&G) and bone-patellar tendon-bone (PAT). Ninety-one young (x = 25.4 years), active patients were available for an average follow-up of 36.4 months and(More)
Until recently, local governments in Spain were using machines with rolling cylinders for verifying taxi-meters. However, the condition of the tires can lead to errors in the process and the mechanical construction of the test equipment is not compatible with certain vehicles. Thus, a new measurement device needs to be designed. In our opinion, the(More)
— Measuring the length of a path that a taxi must fare for is not an obvious task. When driving lower than certain threshold the fare is time dependent, but at higher speeds the length of the path is measured, and the fare depends on such measure. When passing an indoor MOT test, the taximeter is calibrated simulating a cab run, while the taxi is placed on(More)

GPS sensors are a promising technique for verifying taximeters, because they do not require dedicated facilities and are compatible with a wide range of vehicles. The main drawback of this technology is based on legal issues: neither the absolute error of a GPS-based measurement nor the tolerance of the sensor can be known in advance, because they depend on(More)
