The international economy, in the beginning of the 20th century, is characterized by uncertainty about the supply and the price of oil. Together with the fast decrease of electrical propulsion component prices, it becomes more and more cost effective to develop vehicles with alternative powertrains. This paper focuses on two questions: Are alternative powertrains especially cost effective for s...

Robot automation increases productivity, the product quality and frees man from involuntary, unhealthy and dangerous work. While computational power has increased exponentially during the last decades, the limitations in flexibility constitute today a bottleneck in the further evolution of robotic systems. One application for intelligent systems is seam tracking in robotic welding. Seam trackin...

This paper deals with power line communication in vehicle (PLC). PLC is a very promising communication solution in order to offer future in-vehicle applications without increasing wiring harnesses. We join recent additional measurements which have been carried out using modified indoor PLC modems. These PLC modems are based on the two main technologies, HomePLUG AV and HDPLC. Index Terms HomePL...

This paper presents a vehicle dynamics prediction system, which consists of a sensor fusion system and a vehicle parameter identification system. This sensor fusion system can obtain the six degree-of-freedom vehicle dynamics and two road angles without using a vehicle model. The vehicle parameter identification system uses the vehicle dynamics from the sensor fusion system to identify ten vehi...

The fundamental causes of animal-vehicle collisions are unclear, particularly at the level of animal detection of approaching vehicles and decision-making. Deer-vehicle collisions (DVCs) are especially costly in terms of animal mortality, property damage, and safety. Over one year, we exposed free-ranging white-tailed deer (Odocoileus virginianus) to vehicle approach under low ambient light con...

in this paper, a pointwise pseudo-metric function on the l-realline is constructed. it is proved that the topology induced by this pointwisepseudo-metric is the usual topology.

Background: Due to the estrogen participation in modulating the proliferation and commitment of stem cells and the effects of miR-21 and miR-155 expression on reduced proliferation and colony formation of acute myeloid leukemia (AML), the aim of the present study was to evaluate the effect of estradiol on expression of miR-21 and miR-155 in the NB4 cell line, as an acute promyelocytic leukemia ...

We analyze the properties of line of sight (LOS) channels in vehicle-to-vehicle (V2V) communication. We use V2V measurements performed in open space, highway, suburban, and urban environments. By separating LOS from non-LOS data, we show that a two-ray ground reflection path loss model with effective reflection coefficient range fits the LOS channels better than the frequently used free space p...

Bridge expansion joints (BEJs) are equipped at the girder end of long-span railway bridges to ensure reliable transition track. BEJs should have suitable dynamic stiffness running safety and stability vehicle. To explore influence vertical on response vehicle, track, bridge, a three-dimensional vehicle-track-bridge coupled model is established, sleeper spacing vehicle speed taken into considera...
