The object of research is the process circular and surface grinding titanium alloy corrosion-resistant steel, namely, cutting forces arising from mechanical processing. One most problematic areas in work selection required modes, material wheel grain size. In course experiment, we used samples VT8 12Х18N9T on which was studied with wheels made various materials (electrocorundum, cubic boron nit...

Train pneumatic brakes are part of a train safety system, and are thus critical components. This paper illustrates how modeling can be applied to efficiently design such system, from requirement definition to HIL testing. The valves modeling is discussed along with the system level model. Moreover, in order to study the wheel-slide protection device, a model of the wheel-rail interface has been...

For the past ten years, researchers have used the Stable Paths Problem (SPP) to analyze the stability properties of the Border Gateway Protocol (BGP). Analysis of SPP has revealed several combinations of topologies and routing configurations (or gadgets) where BGP cannot converge to a unique stable solution. Researchers typically analyze SPP by hand, using a trial-anderror process to (i) genera...

In this paper, we present the development of a tire rubber deformation sensing system that provides the critical information for understanding and estimation of wheel/ground interactions for mobile robots and vehicles. Polyvinylidene fluoride (PVDF)based sensors are designed and fabricated to embed on the inner tread surface to measure the tire rubber tread deformation. Analytical models of the...

This paper revisited some wheel–workpiece interaction problems in surface grinding including the profile of heat flux and the variation of the wheel’s elastic modulus. A method of using an optical microscope and a CCD camera was applied to capture the depth and width of the heated zone, the details of the temperature field and the stability of the heat flux. It was found that the heat flux in u...

Running wheel access and resulting voluntary exercise alter food intake and reduce body weight. The neural mechanisms underlying these effects are unclear. In this study, we first assessed the effects of 7 days of running wheel access on food intake, body weight, and hypothalamic gene expression. We demonstrate that running wheel access significantly decreases food intake and body weight and re...

In this paper, we propose an implementation of a real-time operating system for the two-wheel mobile robot. With this implementation, we have the ability to control the complex embedded systems of the two-wheel mobile robot. The advantage of the real-time operating system is increasing the reliability and stability of the two-wheel mobile robot when they work in critical environments such as mi...

nloaded purpose of this investigation was to identify pathways by which physical activity, implemented as g in an activity wheel, inhibits carcinogenesis. The focus of this analysis was on 20 plasma biomarr glucose homeostasis, inflammation, cytokine function, and endocrine activity, known to be afby a physically active lifestyle. Plasma for analysis was obtained from previously reported ogenes...

Nb, Ta and Zr are the favorable non-toxic alloying elements for titanium alloys for biomedical applications. Low rigidity titanium alloys composed of non-toxic elements are getting much attention. The advantage of low rigidity titanium alloy for the healing of bone fracture and the remodeling of bone is successfully proved by fracture model made in tibia of rabbit. Ni-free super elastic and sha...

A hardware and software architecture suitable for a safety-critical steer-by-wire systems is presented. The architecture supports three major failure modes and features several safety protocols and mechanisms. Failures due to component failures, software errors, and human errors are handled by the architecture and safety protocols. A test implementation using replicated communication channels, ...
