This paper investigates the fundamental coupling between loads and locational marginal prices (LMPs) in security-constrained economic dispatch (SCED). Theoretical analysis based on multi-parametric programming theory points out the unique one-to-one mapping between load and LMP vectors. Such one-to-one mapping is depicted by the concept of system pattern region (SPR) and identifying SPRs is the...

We have developed systems of two types for NTCIR2. One is an enhenced version of the system we developed for NTCIR1 and IREX. It submitted retrieval results for JJ and CC tasks. A variety of parameters were tried with the system. It used such characteristics of newspapers as locational information in the CC tasks. The system got good results for both of the tasks. The other system is a portable...

In this article, geovisualization is used for the presentation and interpretation of spatial analysis results concerning several house attributes. For that purpose, point data houses in region Attica, Greece are analyzed. The concern sale comprise structural characteristics, such as size, age floor, well locational Geovisualization characteristics performed employing interpolation techniques, k...

Space-time event data are often subject to deficiencies in (1) locational accuracy (2), temporal accuracy and (3) completeness. This work explores how these failings in the quality of input data may affect the results of space-time interaction tests. While previous work has partially investigated the impact of locational inaccuracy on the results of these tests, more work remains. The impacts o...

The rapid introduction of Distributed Energy Resources (DER) into the retail/distribution sector of the electric power system has raised questions concerning both the economics and control of the power system. This paper presents one market paradigm that builds upon extension of the logic of Locational Marginal Pricing into the distribution level arguing that this extension is necessary if ther...

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 controversial Section 8 Housing Choice Voucher program is the largest federal low-income housing program. Using GIS-based spatial clustering analysis (Getis–Ord’s Gi statistic) and multiple linear regressions, in this paper, the authors examine the locational patterns of more than 13,600 Section 8 housing units in Jefferson County, Kentucky, and explore key social, economic, demographic, an...

In a framework where deregulating the electric power market is an objective to be achieved, this thesis investigates how the transmission rules chosen by the regulator to deregulate this market will shape the incentives given to the market players and influence their market power. To study this influence, it is challenging the perfect market assumptions and examining how physical and financial ...

This paper examines racial and ethnic differences in locational attainments in the transition to adulthood, using longitudinal data about neighborhoods of youth in the National Longitudinal Study of Adolescent Health. It examines place stratification and life course models of locational attainment during the 1990s, a period during which neighborhood poverty rates were declining for many groups....

Here we introduce our application of the wavelet analysis method to DNA sequences. In the signal processing field, Fourier transform is popular for analyzing wave data. However, although this method can process frequency information, it fails to handle locational data. In contrast, the wavelet method accommodates both locational and frequency information for wave analysis. The wavelet method is...
