İşaret dilleri, sağırların hem birbirleriyle de diğer kişilerle iletişim kurabildikleri doğal dillerdir. dilleri hakkında toplumda birçok yanlış kanı vardır. Bunlardan en yaygını tüm dünyada tek bir işaret dili kullanıldığı düşüncesidir. Bu durumun temel sebebi, dillerinin yalnızca sağırlar, yakınları ve konuya ilgi duyan küçük kesim tarafından biliniyor olmasıdır. Bunun yanı sıra yeterli düzey...

Subjective impressions of task difficulty, risk, effort, and comfort are key variables of several theories of driver behaviour. A point of difference between many of these theories is not only the importance of these variables, but also whether they are continuously present and monitored or only experienced by individuals at certain critical points in the driving task. Both a threshold relation...

We evaluate the performance of frequent bus services in Edinburgh using the punctuality metrics identified by the Scottish Government. We describe a methodology for evaluating each of these metrics that only requires measurements of bus ‘headways’ — the time between subsequent bus arrivals. Our methodology includes Monte Carlo simulation and time series analysis. Since one metric is given in am...

The authors first reviewed the history of clinical application of artificial ligaments. Then, the status of clinical application of artificial ligaments was detailed. Some artificial ligaments possessed comparable efficacy to, and fewer postoperative complications than, allografts and autografts in ligament reconstruction, especially for the anterior cruciate ligament. At the end, the authors f...

We present an exactly solvable model for queue dynamics. Our model is very simple but provides the essential property for such dynamics. As an example, the model has the traveling cluster solution as well as the homogeneous flow solution. The model is the limiting case of Optimal Velocity (OV) model, which is proposed for the car following model to induce traffic jam spontaneously. The concept ...

This paper is concerned about optimal supply levels for a public transport route within an activity-based simulation framework. In a joint optimization of bus headway and fare, we simulate the interaction between users — who choose mode and departure time according to their activities, timetabling and convenience of the public transport service — and a public transport service provider. Differe...

We study platoon control of vehicles with linear third-order longitudinal dynamics under the constant time headway policy. The controller each follower vehicle is only based on its own velocity, acceleration, inter-vehicle distance and velocity difference respect to immediate predecessor, which are all obtained by on-board sensors. develop distributed cooperative extended state observers for fo...
