The present study describes the development and initial validation of a new obesity-specific, self-report measure of health-related quality of life (HRQOL) for children aged 5-13 years. Participants included 141 obese children (mean age=9.2 years, 67% female, 55% black, mean zBMI=2.52) and their primary caregivers. Children completed Sizing Me Up (obesity-specific HRQOL) and the PedsQL (generic...

An environmentally friendly and inexpensive substitute to the widely used poly(vinyl alcohol) (PVA) has been developed from soy proteins for textile warp sizing. Textile processing is the major source of industrial water pollution across the world, and sizing and desizing operations account for nearly 30 % of the water consumed in a textile plant. PVA is one of the most common sizing agents use...

A variety of Software Sizing approaches have been conjectured in the literature. While many of these approaches have been used for Software Cost Estimation, none were specifically designed for Software Costing. This paper reviews current methods of Software Sizing to determine their suitability for Software Cost Estimation. The approach differs from previous approaches in that it is based on a ...

Konferenzbeschreibung Die IWSM/MetriKon/MENSURA 2008 wurde im vergangenen Jahr von der GI-Fachgruppe 2.1.10 Software-Messung und Bewertung, der kanadischen Gesellschaft für Metrikenanwendung in Montreal (CRIM) und dem Common Software Measurement International Consortium (COSMIC), der Deutsch-sprachigen Anwendergruppe für Software-Metrik und Aufwand-schätzung (DASMA) und der spanischen Community...

Ravindra K. Ahuja and Dorit S. Hochbaum Abstract In this paper, we study capacitated dynamic lot sizing problems with or without backorders, under the assumption that production costs are linear, that is, there are no set up costs. These two dynamic lot sizing problems (with or without backorders) are minimum cost flow problems on an underlying network that possess a special structure. We show ...

Reducing basis weight could lead to huge savings of forest resources as well as energy consumption and waste treatment in the papermaking process. However, low basis weight paper generally lacks normal strength and stiffness. The lower the basis weight of the paper, the more important is surface sizing. Highly cross-linked cured epoxy resin, due to its epoxy group and phenyl group, has gained s...

Recent advanced in the fields of nanotechnology and atmospheric sciences underline the increasing need for sizing sub-10-nm aerosol particles in a simple yet efficient way. In this article, we develop, experimentally test and model the performance of a High-Pass Electrical Mobility Filter (HP-EMF) that can be used for sizing nanoparticles suspended in gaseous media. Experimental measurements of...

In this paper we develop a set of interconnect delay estimation models with consideration of various layout optimizations, including optimal wire-sizing (OWS), simultaneous driver and wire sizing (SDWS), and simultaneous bu er insertion/sizing and wire sizing (BISWS). These models have been tested on a wide range of parameters and shown to have about 90% accuracy on average compared with those ...

As a traditional model in the operations research and management science domain, deterministic lot-sizing problem is embedded in many application problems such as production and inventory planning and has been consistently drawing attentions from researchers. In this paper we consider basic versions of lot-sizing models in which problem parameters are stochastic and develop corresponding scenar...

This paper breaks new ground by modelling lot sizing and scheduling in a flexible flow line (FFL) simultaneously instead of separately. This problem, called the ‘General Lot sizing and Scheduling Problem in a Flexible Flow Line’ (GLSP-FFL), optimizes the lot sizing and scheduling of multiple products at multiple stages, each stage having multiple machines in parallel. The objective is to satisf...
