Galaxy clusters are not iso-thermal, and the radial temperature dependence will affect the cluster parameters derived through the observation of the Sunyaev-Zeldovich (SZ) effect. We show that the derived peculiar velocity will be systematically shifted by 10− 20%. For future all-sky surveys one cannot rely on the observationally expensive X-ray observations to remove this systematic error, but...

Konferenzraum gezeigt. Summary This work lays the foundations for improved thermal comfort in climate-controlled rooms. A methodology is developed which makes it possible to estimate the airflow process in real-time. Based on mathematical modeling, the air temperature and velocity are calculated by virtual sensors at deliberate positions in the room. Therefore, a computationally efficient, data...

We use large eddy simulations with the Euler-Lagrange point-particle approach to assess appropriateness of well-mixed theory in predicting indoor risk contagion. A novel `statistical overloading' technique allows us analyze infinitely many scenarios, only one data-rich simulation. The figure shows droplet nuclei (left half room; see color map for radius `r') and an iso-surface velocity magnitud...

Introduction: The present study aimed to compare the filtration performance between neat hybrid electrospun nanofibers consisting of polyacrylonitrile (PAN) polymer and magnesium oxide (MgO) nanoparticles and plasma treated ones in removing fine particles from the air stream. Methodology: The upper surface of the nanofibers were processed by cold-plasma with a radio frequency power supply (13....

1) RFC 892 is an older version of the ISO Transport Protocol Specification. Therefore this RFC should be assumed to supercede RFC 892. 2) This document has been prepared by retyping the text of ISO/TC97/SC16/N1576 and then applying proposed editorial corrections contained in ISO/TC97/SC16/N1695. These two documents, taken together, are undergoing voting within ISO as a Draft International Stand...

In order to increase the distribution uniformity of sprinkler irrigation systems, some influential parameters such as wind speed, arrangement, space and type of sprinklers must be studied and controlled. In this study, a set of experiments were conducted based on ISO 7749/2(1990) standard to evaluate the ADF 250 and Nelson, F80APV sprinklers. To study the effects of wind velocity, operating pre...

With a dataset of more than 600 million small RNAs deeply sequenced from mouse hippocampal and staged sets of mouse cells that underwent reprogramming to induced pluripotent stem cells, we annotated the stem-loop precursors of the known miRNAs to identify isomoRs (miRNA-offset RNAs), loops, non-preferred strands, and guide strands. Products from both strands were readily detectable for most miR...

The availability of road and vehicle data enables the control vehicles to adapt for different irregularities. Vision-based or stored inform regarding ahead surface conditions. Due these abilities, can be controlled efficiently deal with irregularities in order improve driving comfort stability performances. present paper proposes an integration method intelligent, road-adaptive, semi-active sus...
