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...

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...

Humans adapt the instructions provided in route directions to the assumed spatial knowledge of the receivers; the majority of route directions is provided to wayfinders with at least partial spatial knowledge of the environment. However, today’s navigation systems assume no a-priori knowledge. Most of current research addresses this by exploring means to personalize assistance through the captu...

Aiming at predicting what happens in reality inside mills, the contact parameters of iron ore particles for discrete element method (DEM) simulations should be determined accurately. To allow the irregular shape to be accurately determined, the sphere clump method was employed in modelling the particle shape. The inter-particle contact parameters were systematically altered whilst the contact p...

Large three-dimensional virtual space and walk-through animations are used in navigation systems, games, and movies, etc . In three-dimensional space using the CG data, reality is dependent on the texture quality of buildings. However, the costs for high -quality texture data are also high , which makes it very difficult to reproduce the reality of the real world completely. In this research , ...

Spoken dialogue systems have until recently upheld the simplifying assumption that the conversation between the user and the system occurs in a strict turn-by-turn fashion. In order to have more human-like, uent conversations with computers, a new generation of spoken dialogue systems has arisen that is capable of processing the user’s speech in an incremental way. As the user is speaking, the ...

Predicting the dispersal of pest insects is important for pest management schemes. Flight-mills provide a simple way to evaluate the flight potential of insects, but there are several complications in relating tethered-flight to natural flight. We used high-speed video to evaluate the effect of flight-mill design on flight of the red palm weevil (Rynchophorous ferruginneus) in four variants of ...

A fast gate module has been developed at KEKB, which can pick up a signal of one bunch along a bunch train. The gate module was attached to a tune measurement system and to a turn-by-turn beam-position monitor system. Continuous monitoring of the betatron tune is an indispensable tool to keep the machine in a stable condition. A measurement of the tune along a bunch train is helpful to estimate...

People in dialog use a rich set of nonverbal behaviors, including variations in the prosody of their utterances. Such behaviors, often emotion-related, call for appropriate responses, but today’s spoken dialog systems lack the ability to do this. Recent work has shown how to recognize user emotions from prosody and how to express system-side emotions with prosody, but demonstrations of how to c...
