Over 20 million Tweets were used to study the psychological characteristics of real-world situations over the course of two weeks. Models for automatically and accurately scoring individual Tweets on the DIAMONDS dimensions of situations were developed. Stable daily and weekly fluctuations in the situations that people experience were identified. Predicted temporal trends were found, providing ...

A finite image I is a function assigning colors to a finite, rectangular array of discrete pixels. Thus, the information directly encoded by I is purely locational. Such locational information is of little visual use in itself: perception of visual structure requires extraction of relational image information. A very elementary form of relational information about I is provided by its dipole hi...

Competitive electricity markets which rely on centralized dispatch require a mechanism to solicit offers from competing generators. Ideally, such an auction mechanism provides incentives to submit offers equal to the marginal cost of generation for each generator. Economic theory suggests that the Uniform Price auction is an appropriate institution. However, an efficient implementation of this ...

The present paper discusses a method for robust face recognition that works even when only one image is registered and the test image contains a lot of local noises. Two types of facial image decomposition are compared both theoretically and experimentally. That is, we consider both a projectional decomposition, in which images are decomposed into individuality and other components, and a locat...

This study was conducted to compare the perceptions of park use status, importance, and satisfaction users in first implemented completed Uijeongbu Jikdong Neighborhood Park among private special projects carried out as a countermeasure for long-term non-execution urban parks. To this end, initiated project, apartment residents non-residents were classified according promotion plan, questionnai...

There is now substantial evidence that locational and agglomeration influences can have a significant positive effect on innovation performance. Networking and boundary-spanning activities are also increasingly recognised as important contributors to innovation success. This paper attempts to discover whether these factors are linked: in particular, is there any link between plant location, agg...

Part I of this Essay shows that two central principles of the EC, namely mobility between Member States and decentralization of economic policies (subsidiarity), imply that Member States and other lower-level jurisdictions necessarily are in competition with one another (locational competition). Part II presents an outline of a theory of interjurisdictional competition that suggests, first, tha...

Progress on restructuring of the US power system has been slowed, in part, by the debate over market design and, more specifically, over the design of the congestion management system. This paper proposes a hybrid model that combines the most critical elements of the flowbased and locational marginal price approaches. Specifically, the accounting interface between the simplified network represe...
