The relationships among four descriptors of lactate increase: 1) lactate threshold (LT) (the $$\dot V_{{\text{O}}_{\text{2}} } $$ at which blood lactate concentration begins to increase above the resting level during an incremental exercise test), 2) LT1 (the $$\dot V_{{\text{O}}_{\text{2}} } $$ at which blood lactate increases 1 mM above the resting(More)
In this paper, the existence and uniqueness of the equilibrium point and absolute stability of a class of neural networks with partially Lipschitz continuous activation functions are investigated. The neural networks contain both variable and unbounded delays. Using the matrix property, a necessary and sufficient condition for the existence and uniqueness(More)
The purpose of this investigation was to assess the effect of endurance training based upon the intensity as determined by the arterial blood lactate concentration (LA). Seven healthy male college students performed endurance training on a Monark bicycle ergometer for 15 min on 3 days/week for 8 weeks, at an intensity corresponding to 4 mmol·l−1 arterial(More)
In the sustainable ITS project at the Center for Collaborative Research, the University of Tokyo, an experiment platform is developed for drivers' characteristics analysis on the moving-based driving simulator. In the upper-level microscopic car traffic flow simulator, a prototype driver model and vehicle dynamics model are developed with flexibility in the(More)

Using an open circuit system (Douglas bag method), measurement of the anaerobic threshold (AT) was performed on ten healthy male college students during an incremental exercise test on a bicycle ergometer in an attempt to determine the validity of this method as compared with arterial blood lactate AT measurement. Blood samples were taken from either the(More)
In developing automatic platooning of trucks as an energy-saving technology, the reliable driving of the platooned trucks is a primary objective for public implementation and future applications. At the same time, there is also an emergency requirement to ensure the safety of the driving experiment in the automatic platooning of trucks, including the(More)
User's demand of the quality of streaming service depends on intrinsic characteristics of the content. Various items can be considered as a characteristic. These characteristics are rated on a scale of intensity from 1 to 5. In this paper it is denoted that intensity based on sound or image quality is a characteristic of the content.
