An Industrial Adaptive PID Controller

This paper presents a new industrial adaptive PID controller. The controller has the PID structure, with dual rate sampling, which means that the sampling rate for the PID controller is significantly higher than the sampling rate in the parameter estimator. The controller differs from conventional parametric adaptive controllers because it is based on estimation of transfer function properties. Fo

Inflation Forecasting, Relative Price Variability and Skewness

We aim to forecast U.K. inflation out-of-sample. Our study uses disaggregated quarterly UK consumption data from 1964:1 to 2004:3. A major finding of our analysis is that inflation forecasts of long time horizons of 1.5-2 years are significantly improved if a measure of symmetry of the price distribution is incorporated into the forecast equation. In contrast, the inclusion of price variability le

Xings for Augmented Family Communication

When a child has special communication needs, his or her entire family is affected. This position paper deals with “Xings” (crossings or just xings): active and reactive multisensory media, designed to be communicative on their own terms, challenging existing everyday communication patterns and augmenting family communication. The common shortcomings of oral and written language are no longer crit

Culturally queer, silenced in school? Children with LGBTQ parents, and the everyday politics of/in community and school

Children with lesbian, gay, bisexual, trans* and/or queer (LGBTQ) parents have received heightened attention during the processes of policy making regarding adoption and donor insemination legislation in Sweden during the 1990s and early 2000s. Yet, very little academic knowledge exists about children and young people in LGBTQ families and their experiences in schools. We engage the idea of "cultu

Light Scattering By Multiple Red Blood Cells

The interaction of light with multiple red blood cells was systematically investigated by the finite-different time-domain method. The simulations show that the lateral multiple scattering between red blood cells is very weak. The polarization is shown to have an almost insignificant influence on the distribution of the scattered light. The numerical results were compared with three approximate metho
