Tidskriftsartikel (refereegranskat)abstract
- The PHENIX detector is designed to perform a broad study of A-A, p-A, and p-p collisions to investigate nuclear matter under extreme conditions. A wide variety of probes, sensitive to all timescales, are used to study systematic variations with species and energy as well as to measure the spin structure of the nucleon. Designing for the needs of the heavy-ion and polarized-proton programs has produced a detector with unparalleled capabilities. PHENIX measures electron and muon pairs, photons, and hadrons with excellent energy and momentum resolution. The detector consists of a large number of subsystems that are discussed in other papers in this volume. The overall design parameters of the detector are presented. (C) 2002 Elsevier Science B.V.

Polymer based electrochemical devices for logic functions and paper displays
- 2003
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Here, we report on devices based on patterned thin films of the conducting polymer system poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulphonic acid) (PEDOT:PSS) combined with patterns of solid electrolyte. The key device functionalities base on the updating of the RedOx state of PEDOT. This results in control of the electronic properties of this conjugated polymer, i.e. the conductivity and optical properties are updated. Based on this we have achieved electric current rectifiers, transistors and display cells. Also, matrix addressed displays will be presented. Electrochemical switching is taking place when the oxidation and reduction potentials are overcome respectively. Therefore, these devices operate at voltage levels less then 2 Volts. Low voltage operation is achieved in devices not requiring any extremely narrow dimensions, as is the case for field effect driven devices. All devices reported can or has been made using standard printing techniques on flexible carriers.

The effect of traffic flow improvements on driver attitudes towards pavement markings and other traffic control devices and pedestrian safety

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The author notes that many drivers today, especially those outside of major metropolitan areas, have not ever been pedestrians in the usual way. They may walk to their cars or through parking lots to mall entrances, but they rarely walk on public streets. Since they are not used to being pedestrians, many of them do not know how to behave towards pedestrians when they are behind the wheel of a car. In addition, some of the current traffic flow improvements provide the driver with more choices to make, sometimes leaving the pedestrian to the bottom choice. Right turn on red laws and arrows (and in some states left turn on red is permitted) frequently encourage the pedestrians to race for the curb in order to avoid being hit by the turning vehicle. Radios, cell phones, on board computers, and other amenities available in today's cars further distract the drivers from paying attention to pedestrian pavement markings and the pedestrians in them.
