Automatic building information model query generation

Energy efficient building design and construction calls for extensive collaboration between different subfields of the Architecture, Engineering and Construction (AEC) community. Performing building design and construction engineering raises challenges on data integration and software interoperability. Using Building Information Modeling (BIM) data hub to host and integrate building models is a promising solution to address those challenges, which can ease building design information management. However, the partial model query mechanism of current BIM data hub collaboration model has several limitations, which prevents designers and engineers to take advantage of BIM. To address this problem, we propose a general and effective approach to generate query code based on a Model View Definition (MVD). This approach is demonstrated through a software prototype called QueryGenerator. By demonstrating a case study using multi-zone air flow analysis, we show how our approach and tool can help domain experts to use BIM to drive building design with less labour and lower overhead cost.published_or_final_versio

First observation of cyclotron radiation from MeV-scale epm{\rm e}^{pm} following nuclear beta decay

We present an apparatus for detection of cyclotron radiation that allows a frequency-based beta energy determination in the 5 keV to 5 MeV range, characteristic of nuclear beta decays. The cyclotron frequency of the radiating beta particles in a magnetic field is used to determine the beta energy precisely. Our work establishes the foundation to apply the cyclotron radiation emission spectroscopy (CRES) technique, developed by the Project 8 collaboration, far beyond the 18-keV tritium endpoint region. We report initial measurements of beta^-s from 6He and beta^+s from 19Ne decays to demonstrate the broadband response of our detection system and assess potential systematic uncertainties for beta spectroscopy over the full (MeV) energy range. This work is an important benchmark for the practical application of the CRES technique to a variety of nuclei, in particular, opening its reach to searches for evidence of new physics beyond the TeV scale via precision beta-decay measurements

Guidebook to the Late Pliocene and Early Pleistocene of Nebraska

The interesting geographic and even strategic position of Nebraska between regions of mountain and interior glaciation during the Quaternary was emphasized by A. L. Lugn, Professor Emeritus of Geology at the University of Nebraska, more than thirty years ago. The earlier studies are summarized in two principal works by Lugn (1935; 1939a; see Selected References), to whom this guidebook is dedicated, much has been learned since and much remains to be recorded concerning the Tertiary and Pleistocene of Nebraska. In this centennial year, commemorating the beginning of a second century of geological instruction at the University of Nebraska, it seems best to look ahead, not back. Those who honor the University and the Field Trip Committee by participating in this excursion and the following scientific sessions in Lincoln will surely ask questions which cannot now be answered. In the two days allotted for the trip on the Late Pliocene and Early Pleistocene (Fig. 1) we hope to visit fifteen selected geologic sections, which will give some background for this topic. May we welcome you to Nebraska

Hematology and Blood Chemistry of Wintering Common Cranes

5 paginas y 2 tablesWe studied the hematology and blood chemistry of wintering Common Cranes (Grus grus). Red cell numbers (2.460 × 106 mm-3), hemoglobin content (14.8 g/100 ml), and hematocrit (42.9%) were similar in adult and young birds. Young birds have significantly higher leukocyte numbers (28 × 103 mm-3) than adults (22 × 103 mm-3). Heterophils are the most abundant white blood cells in adults (55%) whereas young have the same proportion of heterophils and lymphocytes (47%). Plasma protein levels are similar in young and adult birds (4.9 g/100 ml), as is the plasma cholesterol level (200 mg/100 ml). However, adults have higher plasma urea levels and lower uric acid and plasma triglyceride levels than young birds (7.1 vs. 5.5 mg/100 ml, 2.9 vs. 4.4 mg/100 ml, and 81 vs. 110 mg/100 ml, respectively).Fieldwork was supported by the DGICYT Project No. PB0389Peer reviewe
