Evaluating the user experience is often done in a laboratory. Methods for observing what happens in the wild are nonetheless being employed because they bring results that the traditional methods of evaluation do not yield. In this paper we describe and discuss methods used at our lab for understanding the mobile user experience. These methods range from quantitative to qualitative evaluation, and

The Kramers-Kronig relations are probably the most well known dispersion relations [1]. These relations relate the real and imaginary parts of the constitutive relations. Summation rules are closely related to dispersion relations, and they ar important for consistency checks as well as deriving various physical bounds. In [2, 3, 4, 5], a summation rule that relates the absorption and scattering c

The existing literature on eco-labeling and green consumerism has been framed within a classical market context where price and quality are the drivers of consumer choice. However, it seems possible that consumers are also concerned about the choices made by other consumers. In fact, it is unclear that people's consumption decisions are made independently of social context. For instance, under the

The classical Kalman-Yakubovich-Popov lemma gives conditions for solvability of a certain inequality in terms of a symmetric matrix. The lemma has numerous applications in systems theory and control. Recently, it has been shown that for positive systems, important versions of the lemma can equivalently be stated in terms of a diagonal matrix rather than a general symmetric one. This paper generali

We prove sharp estimates for the Bergman projection in weighted Bergman spaces in terms of the Bekolle constant. Our main tools are a dyadic model dominating the operator and an adaptation of a method of Cruz-Uribe, Martell and Perez. (C) 2013 Elsevier Inc. All rights reserved.

The Seebeck coefficient, a key parameter describing a material's thermoelectric performance, is generally difficult to measure, and no intrinsic calibration standard exists. Quantum dots and single electron tunneling devices with sharp transmission resonances spaced by many kT have a material-independent Seebeck coefficient that depends only on the electronic charge and the average device temperat

The physics of interacting many-body systems is a very complex and challenging subject. Therefore one in general needs to use simplified models and approximate methods for studying these systems theoretically. In this work we study the exchange-correlation (xc) potential for the Hubbard-Holstein (HH) model for the application of Density Functional Theory (DFT) to the same. The Hohenberg-Kohn theo

Sex trafficking has from six hundred thousand to four million victims each year (McCabe and Manian, 2010: 41-43). Because of different legal barriers, sex trafficking is closely associated with organized crime; crime victims often do not search for support from legal systems, law enforcement authorities, or other officials (ibid.) This thesis was to understand how law affects the ability of preven
