Producing Mega-pixel CMB Maps from Differential Radiometer Data

A major goal of cosmology is to obtain sensitive, high resolution maps of the Cosmic Microwave Background (CMB) anisotropy. Such maps, as would be produced by the recently proposed Microwave Anisotropy Probe (MAP), will contain a wealth of primary information about conditions in the early universe. To mitigate systematic effects when observing the microwave background, it is desirable for the raw data to be collected in differential form: as a set of temperature differences between points in the sky. However, the production of large (mega-pixel) maps from a set of temperature differences is a potentially severe computational challenge. We present a new technique for producing maps from differential radiometer data that has a computational cost that grows in the slowest possible way with increasing angular resolution and number of map pixels. The required central processor (CPU) time is proportional to the number of differential data points and the required random access memory (RAM) is proportional to the number of map pixels. We test our technique, and demonstrate its feasibility, by simulating one year of a space-borne anisotropy mission.Comment: 8 pages Latex with 3 Postscript figures embedded using eps

Improving Load Calculations for Fenestration with Shading Devices

Additional reproduction, distribution, or transmission in either print or digital form is not permitted without ASHRAE’s prior written permission.Activities and findings arising from ASHRAE Research Project 1311-RP are summarized. This project included three main goals, (a) development of models for pleated drapes, venetian blinds, roller blinds and insect screens, (b) implementation of these models in the ASHRAE Loads Toolkit, and (c) compilation of results suitable for direct application in building cooling load methods such as Radiant Time Series (RTS). The solar and heat transfer interactions present in multilayer systems are complicated and the corresponding models entail significant complexity. This work produced the ASHRAE Window Attachment (ASHWAT) model that uses a simplified approach to the way in which radiation interacts with each glazing or shading layer. Each layer is assigned spatially-averaged “effective” optical properties so that glazing and shading layers can be arranged in any combination. ASHWAT offers wide scope in the design process, the possibility of active control (e.g., slat angle adjustment), fast computation, and facilitates the implementation of additional shading layer types. Very few input data are needed to model any layer. Measurement-based validation was undertaken at both the subcomponent level and at the complete system level with documentation in the technical literature. The ASHWAT model has been added to the ASHRAE Loads Toolkit and coupled to the heat-balance room model, supporting accurate calculation of cooling load impact of fenestration shading. Simplified correlation models were developed to allow shaded fenestration performance estimates via spreadsheet-tractable formulas. The model was also used to generate greatly expanded simplified data for inclusion in Fundamentals and suitable for direct use in widely-used engineering proceduresNatural Resources Canada (NRCan) || Natural Sciences and Engineering Research Council (NSERC
