There have been several attempts to describe traffic flow behaviour by modelling the relationship between the main variables describing traffic such as speed, flow and density. Some of these models are based on simplistic assumptions and therefore, they are far from being accurate in representing the whole range of traffic conditions (e.g. from free flowing to congested situations). This paper ...

This paper proposes a divider structure that combines a novel self-timed ring structure and a carry-propagation-free division algorithm. The self-timed ring structure enables the divider to compute at a speed comparable to that of previously designed dividers with less silicon area. By exploiting the carry-propagation-free division algorithm, we can achieve even better performance. We designed ...

Wepresent results from a systemwhich uses received signal strength (RSS) measurements to estimate the speed at which a person is walking when they cross the link line. While many RSS-based device-free localization systems can detect a line crossing, this system estimates additionally the speed of crossing, which can provide signi€cant additional information to a tracking system. Further, unlike...

Background: Excessive range of adductory free moment of the ground reaction force may potentially increase the risk of lower extremity injuries by applying a higher torsional load transmitted to the proximal parts. Objective: It was hypothesized that the free moment pattern might be different between hyper-pronated and normal feet subjects. Moreover, a correlation would exist between peak...

the study deals with noise problems associated with the use of air-turbine drills in dental practice. noise level measurements were made on various types of dental handpieces, when operated free running and when used to cut tooth tissue. hearing acuity tests were also undertaken in 12 randomly selected dental surgeons who have been using these drills for a number of years. the results indicate ...

In this paper, a relatively new method, namely variational iteration method (VIM), is developed for free vibration analysis of a Timoshenko beam with different boundary conditions. In the VIM, an appropriate Lagrange multiplier is first chosen according to order of the governing differential equation of the boundary value problem, and then an iteration process is used till the desired accuracy ...

the aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel moldpowders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samplescontaining such compositions as mno, fe2o3, li2o, tio2 and zno, as well as another fluorine-free samplecontaining a combination of fe2o3 and tio2, were prepared in this research...

The performance of many traffic control strategies depends on how much the traffic flow models have been accurately calibrated. One of the most applicable traffic flow model in traffic control and management is LWR or METANET model. Practically, key parameters in LWR model, including free flow speed and critical density, are parameterized using flow and speed measurements gathered by inductive ...

We consider ways to increase calculational speed for Ewald of crystal summations in cases where standard combination rules do not apply. This also increases in the speed for the free-energy perturbation theory calculations.
