The purpose of this study was to examine the effects of load carrying methods, stair slopes and walking speeds on heart rate and walking postures. Nine participants climbed up and down stairs with various stair slopes (24°, 30° and 36°), walking speeds (72, 96, and 132 steps per minute), and using different load carrying methods (empty loads, backpack, and hand-held). The effects of these facto...

Real-time databases have numerous applications, including commodities trading, military command and control, patient monitoring, air tra c control, and exible manufacturing. All of these applications require that data be processed in such a way that the data and output of the database remains logically consistent . They also require that deadlines imposed on database operations are met (tempora...

The article considers and calculates the brake system of a two-axle service diesel motor car, consisting two subsystems acting separately on axles provided that each axle is served by one cylinder 501b. A calculation was made in order to evaluate effectiveness friction tread car model AS-01uz.

Live attenuated SA-14-14-2 vaccine against Japanese encephalitis (JE) was introduced in the routine immunization under Universal Immunization Program in the 181 endemic districts of India. Recently, the Government of India has announced the introduction of one dose of JE vaccine for adults in endemic districts. The policy to mass vaccinate adults has raised several concerns that are discussed i...

Introduction The use of visual guidance, or targeting, to tread on a force platform while walking has been reported as a potentially confounding factor in gait research (Oggero et al., 1997). While there is evidence that constraining the foot to a specific area within a walkway alters stepping parameters (Hirokawa, 1989) and promotes the use of visual control strategies (Patla et al., 1996), th...

Today we move on to the final section of material on quantum optical communication: the full multi-temporal mode treatments of electromagnetic field quantization, photodetection theory, nonlinear optics, non-classical light generation, and quantum interference. Because our prerequisite subjects—6.011 and 18.06—do not include enough background for these topics, we’ll tread gently. Hence there wi...

This paper proposes a simple mathematical tyre model that estimates tyre cornering stiffness. The model is derived by considering the tyre to be a combination of two independent systems. The sidewalls are assumed to be negligibly stiff in the lateral direction, and hence their influence on the lateral dynamics of the tyre will be ignored. The belt and tread area of the tyre will be considered t...
