This paper shows that the driving simulator may be used as a platform in which to study workload and workload performance relationship. The participants were 8 adults with valid driver’s licenses. After a familiarization drive participants drove a route with five equidistant and symmetrical segments using a map and turn-by-turn directions. Upon completion participants retraced their journey wit...

This paper provides a system dynamic model for reducing the number of motorway accidents due to wrong-way driving. Motorway accidents are often fatal due to high speeds. It is therefore necessary to carry out all the possible countermeasures in order to achieve adequate traffic management. One of the reasons for motorway accidents is driving in the wrong direction. Based on the analysis of the ...

The neutral Higgs boson is expected to have a mass in the region 90-150 GeV/c2 in various schemes within the Minimal Supersymmetric extension to the Standard Model. A first generation Muon Collider is uniquely suited to investigate the mass, width and decay modes of the Higgs boson, since the coupling of the Higgs to muons is expected to be strong enough for it to be produced in the s channel m...

Mobile phones have become ubiquitous in daily life. They are also becoming more powerful with more computation and a variety of sensors embedded in them. We have built deSCribe, a context-aware phone-based navigational aid. The application provides turn-by-turn directions from the user’s current location to a requested destination. It provides information about the surroundings by processing th...

SSRL designed and built beam position electronics for its SPEAR storage ring. We designed the electronics, using digital receiver technology, for highly accurate turn by turn measurements of both the position and arrival time of the beam, allowing us to use this system to measure the betatron and synchrotron tunes of the beam. The dynamic range of the system allows us to measure the properties ...

We study random assignment economies with expectedutility agents, each of them eventually obtaining a single object. Inspired on Hylland and Zeckhauser’s (1979) Pseudomarket mechanism (PM) and on a serial dictatorship, we introduce the Sequential Pseudomarket (SP) where groups of agents are called turn by turn and participate in a pseudomarket for the remaining objects. To measure e¢ ciency, we...

Java is the ideal development platform for mobile code systems. It ensures application portability and mobility for a variety of platforms, while providing strong security features. The intermediate code (byte code) allows us to verify statically (i.e. during loading phase) that the program is trustworthy. This is done by a software security module called the byte code verifier. Given the compl...

The U-turn is a classical three-dimensional RNA folding motif first identified in the anticodon and T-loops of tRNAs. It also occurs frequently as a building block in other functional RNA structures in many different sequence and structural contexts. U-turns induce sharp changes in the direction of the RNA backbone and often conform to the 3-nt consensus sequence 5'-UNR-3' (N = any nucleotide, ...

Measurement and control of the tunes, coupling, and chromaticities in storage rings is essential to efficient operation of these accelerators. Yet it has been very difficult to make reliable realtime measurements of these quantities. We have built and commissioned the microprocessorbased Generic Finite State Data Acquisition (GFSDA) system. GFSDA provides turn-by-turn data acquisition and analy...

A single bunch of charged particles in a storage ring is a system of 10-10 coupled non-linear oscillators with radiative energy loss and compensated by the accelerating cavity. A stable collective mode in such system was induced and observed in the SPEAR storage ring using a turn-by-turn phase space monitor. New possibilities of using this mode as a tool to experimentally study non-linear dynam...
