Lunar Meteoroid Impacts and How to Observe Them
Author: Brian CudnikPublisher: Springer Science & Business Media
ISBN: 1441903240
Category : Science
Languages : en
Pages : 242
Book Description
The genesis of modern searches for observable meteoritic phenomena on the Moon is the paper by Lincoln La Paz in Popular Astronomy magazine in 1938. In it he argued that the absence of observed fashes of meteoritic impacts on the Moon might be interpreted to mean that these bodies are destroyed as luminous meteors in an extremely rarefed lunar atmosphere. The paper suggested the possibility of systematic searches for such possible lunar meteors. With these concepts in mind, I was surprised to note a transient moving bright speck on the Moon on July 10, 1941. It appeared to behave very much as a lunar meteor would – except that the poorly estimated duration would lead to a strongly hyperbolic heliocentric velocity. Thus, the idea of systematic searches for both p- sible lunar meteors and meteoritic impact fashes was born. It was appreciated that much time might need to be expended to achieve any positive results. Systematic searches were carried out by others and myself chiefy in the years 1945–1965 and became a regular program at the newly founded Association of Lunar and Planetary Observers, or ALPO.
Venus and Mercury, and How to Observe Them
Author: Peter GregoPublisher: Springer Science & Business Media
ISBN: 0387742867
Category : Science
Languages : en
Pages : 265
Book Description
Venus and Mercury have long been regarded as difficult targets for amateur observers, but advances in commercially-made telescopes have brought them within the skills of observers of only moderate experience. Peter Grego’s fascinating book presents an up-to-date, detailed description of the history and geology of the so-called inferior planets, and provides the latest, most useful advice on observing and recording them with commercially-available telescopes and cameras. The book also offers a wealth of detailed practical information on every aspect of observing, from safely targeting the two planets, through visual observing, to sketching and electronic imaging.

Author: A Satellite-Based Multi-Channel Approach to Tropical Cyclone Intensity Estimation Using the AMSU Passive Microwave Sensor
Author: Brian W. KabatPublisher:
ISBN:
Category : Science
Languages : en
Pages : 156
Book Description
In tropical cyclones, a strong inverse relationship exists between the magnitude of the upper-tropospheric warm anomaly (UTWA) and minimum sea level pressure (MSLP). Uniquely poised to capture this warming aloft, the Advanced Microwave Sounding Unit (AMSU) flown aboard current National Oceanic and Atmospheric Administration (NOAA) polar-orbiting satellites is capable of observing Tropical Cyclones (TC's) worldwide. A physical/statistical MSLP estimation algorithm based on AMSU brightness temperature anomalies (dTbs) has been operating in an experimental mode at the University of Wisconsin Cooperative Institute for Meteorological Satellite Studies (UW-CIMSS) for two years. The algorithm relies on a single AMSU channel (54.9 GHz) and shows great promise as a viable TC analysis tool. However, the radiances can be susceptible to environmental variability leading to sub-sampling and errors in MSLP. The goal of this research is to improve the existing single-channel algorithm by introducing an additional channel (55.5 GHz) that seeks to capture the true magnitude of the UTWA in instances when the single channel fails. By implementing the multi-channel approach, the goal is to create an operationally viable satellite-based guidance tool to help support tropical forecast and analysis centers worldwide.

Game Audio Programming 4
Author: Guy SombergPublisher: CRC Press
ISBN: 100099841X
Category : Computers
Languages : en
Pages : 356
Book Description
Welcome to the fourth volume of Game Audio Programming: Principles and Practices – the first series of its kind dedicated to the art, science, and craft of game audio programming. This volume contains 17 chapters from some of the top game audio programmers in the industry and dives into subjects that apply to diverse game genres and from low-level topics such as thread-safe command buffers and pitch detection to high-level topics such as object management, music systems, and audio tools. With such a wide variety of topics, game audio programmers of all levels will find something for them in this book. The techniques presented in this book have all been used to ship games, including some large AAA titles, so they are all practical and many will find their way into your audio engines. There are chapters about timed ADSRs, data-driven music systems, background sounds, and more. This book collects a wealth of advanced knowledge and wisdom about game audio programming. If you are new to game audio programming or a seasoned veteran, or even if you’ve just been assigned the task and are trying to figure out what it’s all about, this book is for you!
Cladh Hallan - Roundhouses and the dead in the Hebridean Bronze Age and Iron Age
Author: Mike Parker PearsonPublisher: Oxbow Books
ISBN: 1789256968
Category : Social Science
Languages : en
Pages : 568
Book Description
This first of two volumes presents the archaeological evidence of a long sequence of settlement and funerary activity from the Beaker period (Early Bronze Age c. 2000 BC) to the Early Iron Age (c. 500 BC) at the unusually long-occupied site of Cladh Hallan on South Uist in the Western Isles of Scotland. Particular highlights of its sequence are a cremation burial ground and pyre site of the 18th–16th centuries BC and a row of three Late Bronze Age sunken-floored roundhouses constructed in the 10th century BC. Beneath these roundhouses, four inhumation graves contained skeletons, two of which were remains of composite collections of body parts with evidence for post-mortem soft tissue preservation prior to burial. They have proved to be the first evidence for mummification in Bronze Age Britain. Cladh Hallan’s remarkable stratigraphic sequence, preserved in the machair sand of South Uist, includes a unique 500-year sequence of roundhouse life in Late Bronze Age and Iron Age Britain. One of the most important results of the excavation has come from intensive environmental and micro-debris sampling of house floors and outdoor areas to recover patterns of discard and to interpret the spatial use of 15 domestic interiors from the Late Bronze Age to the Early Iron Age. From Cladh Hallan’s roundhouse floors we gain intimate insights into how daily life was organized within the house – where people cooked, ate, worked and slept. Such evidence rarely survives from prehistoric houses in Britain or Europe, and the results make a profound contribution to long-running debates about the sunwise organisation of roundhouse activities. Activity at Cladh Hallan ended with the construction and abandonment of two unusual double-roundhouses in the Early Iron Age. One appears to have been a smokery and steam room, and the other was used for metalworking.
