This paper studies the allocation of goods to agents without monetary transfers and incomplete information. Agents’ have private, multi-dimensional utilities over goods, drawn from commonly known priors, possibly asymmetric across agents’ types. Both cardinal and ordinal mechanisms are studied. For tractability, a large market approximation is considered with a continuum of agents for each type...

This paper presents an application of a distributed service-oriented architecture (FIPER) to the preliminary design of gas turbine. In this application, a one-dimensional analysis code is wrapped into an interface to create a network service. Several of these services are distributed across a grid of workstations. The FIPER architecture uses a service catalog that registers all the services tha...

Many critical loads rely on simple backup generation to provide electricity in the event of a power outage. An Energy Surety Microgrid can protect against outages caused by single generator failures to improve reliability. An ESM will also provide a host of other benefits, including integration of renewable energy, fuel optimization, and maximizing the value of

Data analysis plays a central role in our attempts to understand the behavior of complex systems. While research in both statistics and arti cial intelligence has addressed issues in the automation of later stages of analysis, such as theory generation, model selection, and experiment design [7], less attention has been given to initial exploration of data. Deriving structure from data is never...

In 1962 the Committee on Prosthetics Research and Development authorized a survey of current orthotics research and development in a number of selected centers as an initial step in a proposed orthotics evaluation program. A prime purpose of the survey was the identification of orthotic devices and procedures as suitable subject matter for the evaluation program. One of the devices selected as ...

SINCE interest is being increasingly extended to pupillography, a means has been devised to overcome the great loss of time involved in the conventional method. Instead of demanding a laborious measuring of each separate picture, this method allows a comprehensive view of the pupil reaction. The eye is focused on a film which moves slowly ina vertical direction. Very near to the film is fixed a...

Chagas disease (CD) is an important cause of cardiomyopathy and stroke in Brazil. Brain infarcts and atrophy seem to occur independently of cardiomyopathy severity and cognitive impairment is understudied. Objective: Compare the prevalence of brain magnetic resonance imaging abnormalities between patients with or without CD; determine if inflammatory biomarkers are increased in CD; and determin...

The paper presents a method for the preliminary design of parts using fuzzy logic and object-oriented design databases, in order to increase the efficiency of the design process. The method can be used to rapidly produce geometric models and drawings that can be used as a starting point for the detailed design phase.

This paper describes the vital role of freehand sketching in the design process. When designers first tackle a design problem they usually do so by sketching. We will explore the essential elements of sketching that make it so helpful to problem solving. We then examine how current computer interfaces interfere with the sketching process, and go on to establish the requirements for an environme...
