Hi, I am trying using the bibtex import using exports from various sites, e.g. and on EndNote All of these exports fail due to different reasons. Example files are atteched. Endnote does not have the key, mathscinet and engineering village have extra spaces. Where as I would think that it is these exports that are incorrect, is it possible to add some additional code to make the import more compatible with these. Thanks Matt

These data sets mimic the late stages of coalescing black holes. We compare various aspects of the evolution of axisymmetric initial data sets, obtained with this 3D code, to results obtained from a well established axisymmetric code. In both codes we examine and compare the behavior of metric functions, apparent horizon properties, and wave forms, and show that these dynamic black holes can be accurately evolved in 3D. In particular we show that with present computational resources and techniques the process of excitation and ringdown of the black hole can be evolved, and one can now extract accurately the gravitational waves emitted from the 3D Cartesian metric functions, even when they carry away only a small fraction (<<1%) of the rest mass energy of the system. Wave forms for both the l=2 and the much more difficult l=4 and l=6 modes are computed and compared with axisymmetric calculations. In addition to exploring the physics of distorted black hole data sets, and showing the extent to which the waves can be accurately extracted, these results also provide important testbeds for all fully nonlinear numerical codes designed to evolve black hole spacetimes in 3D, whether they use singularity avoiding slicings, apparent horizon boundary conditions, or other evolution methods}, keywords = {black holes general relativity gravitation gravitational waves}, year = {1999} }

The aim of the system is to detect the presence of obstacles (targets) in the surrounding area and in addition to determine their positions and ultimately follow their movements. The advantage of using radar for this purpose is that unlike the sensors based on other physical principles (optical, ultrasound), its performance is insensitive to the illumination level, atmospheric disturbances (like fog) or acoustic noise in the environment.

These systems address straight-crossing-path crashes at signalized intersections. System components include sensors, processors, driver information devices, roadside-to-vehicle communication systems, and on-vehicle systems. The deployment model to realize infrastructure vehicle cooperation assumes the introduction of infrastructure-only systems that service all drivers with warnings provided by roadside information devices. These systems would be followed by the addition of roadside-to-vehicle communication systems that service drivers of intelligent vehicles through in-vehicle warnings. These concepts can be used to avoid a crash when a vehicle violates the signal. Equations of motion illustrate how a simple algorithm can be used to identify potential violators by using speed at a measurement point on the approach to an intersection. The example suggests that most potential signal violators can be warned in time to stop before they collide with a vehicle from the cross street. Analysis also indicates that when warnings of the possible signal violation are conveyed to drivers on the cross street, many of these drivers can also stop before colliding with the signal violator. In the example, 88% of the relevant straight-crossing-path crashes were addressed by providing timely warnings to either the violators or the other drivers. Deployment costs and benefits were estimated to demonstrate the potential value of infrastructure intersection collision-avoidance systems.}, key = {Intelligent vehicle highway systems}, keywords = {Collision avoidance;Intersections;Roadsides;Traffic signals;Vehicle actuated signals;}, note = {Infrastructure vehicle cooperative collision avoidance systems;Roadside to vehicle communication systems;Signalized intersections;}, } @inproceedings{2002367072517 , language = {English}, copyright = {Compilation and indexing terms, Copyright 2011 Elsevier Inc.}, copyright = {Compendex}, title = {Performance analysis of the collision avoidance procedure of the advanced infrared (AIr) CSMA/CA protocol for wireless LANs}, journal = {IEEE Vehicular Technology Conference}, author = {Vitsas, V. and Boucouvalas, A.C.}, volume = {3}, year = {2002}, pages = {1502 - 1506}, issn = {07400551}, address = {Birmingham, AL, United states}, abstract = {The Infrared Data Association (IrDA) Advanced Infrared (AIr) protocol for indoor optical wireless LANs is examined. AIr Medium Access Control (MAC) layer utilizes a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) scheme to coordinate medium access. To deal with hidden stations, AIr employs a Request To Send/Clear To Send (RTS/CTS) reservation scheme and a long Collision Avoidance Slot (CAS) duration that includes the beginning of receiver's CTS packet. AIr employs linear adjustment of the Contention Window (CW) size to minimize delays emerging from the long CAS duration. This paper develops an analytical model for the Collision Avoidance scheme of the AIr protocol that computes throughput performance assuming error free transmissions and a fixed number of stations. The model is validated by comparing analysis with simulation results. By differentiating the throughput equation, optimum CW size that maximises throughput as a function of the number of the transmitting stations is derived. In the case of AIr protocol where a collision lasts exactly one CAS, different conclusions result for maximum throughput as compared with the corresponding conclusions for the similar IEEE 802.11 protocol. By employing the analytical model, throughput performance for various parameter values is evaluated. The proposed linear CW adjustment is very effective in minimizing delays emerging from empty slots and collisions during the contention period. Linear CW adjustment combined with the long CAS duration provides an effective protection from collisions caused by hidden stations and offers an attractive collision avoidance scheme.}, key = {Network protocols}, keywords = {Approximation theory;Carrier sense multiple access;Collision avoidance;Computer simulation;Differentiation (calculus);Local area networks;Mathematical models;Optical communication;Wireless telecommunication systems;}, note = {Advanced Infrared protocol;Collision Avoidance Slot;Medium Access Control;}, URL = {}, }
