PURPOSE The purpose of this study was to compare the effects of local and general fatigue loads on knee proprioception. TYPE OF STUDY Experimental controlled study. METHODS Proprioception of the knee joint was evaluated by measuring absolute angular error (AAE) at matching defined index angles before and after 2 different types of fatigue protocols (local load and general load) in 27 health...

The study of balls-into-bins games or occupancy problems has a long history since these processes can be used to translate realistic problems into mathematical ones in a natural way. In general, the goal of a balls-into-bins game is to allocate a set of independent objects (tasks, jobs, balls) to a set of resources (servers, bins, urns) and, thereby, to minimize the maximum load. In this paper ...

Kinetics of sarcomere movement were studied in real-time by laser diffraction. Instantaneous sarcomere shortening was measured during afterloaded twitches simultaneously with instantaneous shortening and tension of the whole trabecula excised from rat right ventricle. Resting sarcomere length at optimal length was 2.20 +/- 0.02 micron (mean +/- SEM). Maximum amplitude of sarcomere shortening wa...

The bridge-type bridge crane is a common lifting equipment used in modern factories and workshops. During the crane’s operation, positioning of trolley swing load can significantly impact safety reliability. In this paper, we propose variable universe fuzzy multi-parameter self-tuning PID (VUFMS-PID) control strategy for controlling trolley’s movement. Our uses scaling factor variation to dynam...

Parallel applications commonly face the problem of sitting idle while waiting for remote data to become available. Even for problems where plenty of parallelism is available and good load balance is achievable, performance may be disappointing if local work cannot be overlapped with communication. We describe three patterns for achieving the overlap of communication with computation: overdecomp...

Abstract To study the teaching of sports science in athletics, this paper adopts method a nonlinear mathematical equation, According to explosive power = force * speed and hill best matching value between load weight muscle contraction when athlete reaches maximum is obtained by method, achieve objective quantifying scientifying training according individual ability athlete. The results show th...

Prediction of peak loads in Iran up to year 2011 is discussed using the Radial Basis Function Networks (RBFNs). In this study, total system load forecast reflecting the current and future trends is carried out for global grid of Iran. Predictions were done for target years 2007 to 2011 respectively. Unlike short-term load forecasting, long-term load forecasting is mainly affected by economy...

The force-velocity relations of single glycerinated rabbit psoas muscle fibers at 5 degrees C were studied at maximum and half-maximum activation in the presence of 0 (control) and 39-145 g/liter dextran T-70. Resting fiber diameter decreased progressively to approximately 70% of the nondextran control as the dextran concentration was increased. Isometric force at full activation increased to a...

OBJECTIVE The purpose was to determine if Soldier rucksack load, marching distance, and average heart rate (HR) during shooting affect the probability of hitting the target. BACKGROUND Infantry Soldiers routinely carry heavy rucksack loads and are expected to engage enemy targets should a threat arise. METHOD Twelve male Soldiers performed two 11.8 km marches in forested terrain at 4.3 km/h...
