Jobsite Cameras Past, Present, Future
Jobsite Cameras Past, Present, Future How jobsite cameras are evolving in use and capability By David Gaw, Founder, CEO – Sensera Systems Jobsite cameras have become an essential tool for the modern connected jobsite. Understanding these systems and how they support construction best practices is important in today’s ever-expanding jobsite technology array. In this article, we’ll take a look at the evolution of jobsite cameras and how they are impacting the construction industry. WHAT IS A ‘JOBSITE CAMERA’? A jobsite camera is simply a camera that is used on a construction site to provide automated capture of imagery and/or video. Most would also agree that a jobsite camera is one that is network connected to allow for remote viewing and image retrieval. However, there are some more basic devices used on jobsites that record images and video to local storage for periodic manual retrieval by the user. For the purposes of our discussion here we will consider only network-connected cameras, since non-connected cameras are typically not suitable for commercial construction project applications. In addition to the camera hardware itself, a ‘jobsite camera’ typically also incorporates software that provides the following basic functions (at minimum): • Remote configuration of the camera operation • Viewing of images and video • Remote long-term storage of images and video (e.g., cloud-based storage) • Creation of time-lapse videos from individual still images collected at specified intervals BACK IN THE DAY The initial jobsite cameras grew out of early ‘webcam’ applications. A webcam is a camera that is connected to the Internet (or the Web), to allow for remote real-time viewing. -

Some Comments on the Tests of General Relativity
Some Comments on the Tests of General Relativity. M. Anyon and J. Dunning-Davies, Department of Physics, University of Hull, Hull HU6 7RX, England. Email: [email protected] Abstract A brief outline of the history of the discrepancies within Newtonian mechanics at the end of the 19th Century is given. The framework of General Relativity is briefly described and the famous ‘tests’ of General Relativity (GR) are considered and alternative solutions are discussed, with particular attention concentrating on the advance of the perihelion of the planet Mercury. The implications for the claims of relativity are discussed, all with reference to both pre and post 1915 publications. 1 Introduction The aim of this article is to address the notion that the well known classic ‘tests of general relativity’ - The Anomalous Precession of the Perihelion of the Planet Mercury, The Gravitational Red-shift and The Gravitational Deflection of Light-rays - may be explained and derived with no reference to Einstein’s theory of general relativity. The intention is to provide evidence that these phenomena can be explained and interpreted without the framework of general relativity, by using both modern sources and publications, as well as work that was published prior to Einstein’s work. By providing evidence that these phenomena could, and were explained, via classical mechanics before 1915, it will be possible to make a case against those that say anyone who questions general relativity is ‘obviously’ mistaken. Theories of the Relativity of Motion. The General Theory of Relativity (GR), proposed by Albert Einstein in 1915, was heralded as one of the most ground-breaking and complicated theories in physics when it was first published, and is still considered one of the greatest physical and mathematical theories of the universe at large today. -
Digital Camera Fully Compatible, Newly Developed S-TTL System
Digital Camera Fully Compatible, Newly Developed S-TTL System "S-TTL" enables TTL auto shooting by an external strobe for a digital SLR camera as well as for a point & shoot digital camera. INON S-TTL auto strobe supports any manufactures' model providing highly accurate exposure control. Film camera era without strobe selection problem TTL stands for "Through The Lens" and TTL auto strobe system controls flash amount to provide correct exposure based on calculation by camera's internal sensor metering reflecting strobe light from a subject through the lens. This TTL system meters actual light amount reflecting from a subject providing accurate exposure. When we start with the history of underwater TTL auto strobe, underwater camera "NIKONOS V" released in 1984 was the first to provide automatic TTL flash control for underwater strobe SB-102, SB-103 succeeded by NIKONOS V compatible underwater strobes form other manufactures. The 5 pin electrical sync connector for NIKONOS V is most popular and widely adopted to connect an underwater strobe and underwater film camera (underwater camera / housing). A film SLR camera has flexibility to select an underwater strobe. As far as housing has NIKONOS type electrical sync connector and properly NIKONOS type 5 pin electrical wired, automatic TTL flash control is usable with any TTL auto strobe sync connector and NIKONOS V like Nikon SB-105, INON Z-220, Z-22 connected via electrical sync with INON Z-22 strobe cable. Film camera compatible strobe is not usable for a digital camera!? Underwater TTL strobe circumstances have been drastically altered with the spread of digital camera among divers. -

A Review on Substellar Objects Below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs Or What?
geosciences Review A Review on Substellar Objects below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs or What? José A. Caballero Centro de Astrobiología (CSIC-INTA), ESAC, Camino Bajo del Castillo s/n, E-28692 Villanueva de la Cañada, Madrid, Spain; [email protected] Received: 23 August 2018; Accepted: 10 September 2018; Published: 28 September 2018 Abstract: “Free-floating, non-deuterium-burning, substellar objects” are isolated bodies of a few Jupiter masses found in very young open clusters and associations, nearby young moving groups, and in the immediate vicinity of the Sun. They are neither brown dwarfs nor planets. In this paper, their nomenclature, history of discovery, sites of detection, formation mechanisms, and future directions of research are reviewed. Most free-floating, non-deuterium-burning, substellar objects share the same formation mechanism as low-mass stars and brown dwarfs, but there are still a few caveats, such as the value of the opacity mass limit, the minimum mass at which an isolated body can form via turbulent fragmentation from a cloud. The least massive free-floating substellar objects found to date have masses of about 0.004 Msol, but current and future surveys should aim at breaking this record. For that, we may need LSST, Euclid and WFIRST. Keywords: planetary systems; stars: brown dwarfs; stars: low mass; galaxy: solar neighborhood; galaxy: open clusters and associations 1.

Theory and Experiment in the Quantum-Relativity Revolution
Theory and Experiment in the Quantum-Relativity Revolution expanded version of lecture presented at American Physical Society meeting, 2/14/10 (Abraham Pais History of Physics Prize for 2009) by Stephen G. Brush* Abstract Does new scientific knowledge come from theory (whose predictions are confirmed by experiment) or from experiment (whose results are explained by theory)? Either can happen, depending on whether theory is ahead of experiment or experiment is ahead of theory at a particular time. In the first case, new theoretical hypotheses are made and their predictions are tested by experiments. But even when the predictions are successful, we can’t be sure that some other hypothesis might not have produced the same prediction. In the second case, as in a detective story, there are already enough facts, but several theories have failed to explain them. When a new hypothesis plausibly explains all of the facts, it may be quickly accepted before any further experiments are done. In the quantum-relativity revolution there are examples of both situations. Because of the two-stage development of both relativity (“special,” then “general”) and quantum theory (“old,” then “quantum mechanics”) in the period 1905-1930, we can make a double comparison of acceptance by prediction and by explanation. A curious anti- symmetry is revealed and discussed. _____________ *Distinguished University Professor (Emeritus) of the History of Science, University of Maryland. Home address: 108 Meadowlark Terrace, Glen Mills, PA 19342. Comments welcome. 1 “Science walks forward on two feet, namely theory and experiment. ... Sometimes it is only one foot which is put forward first, sometimes the other, but continuous progress is only made by the use of both – by theorizing and then testing, or by finding new relations in the process of experimenting and then bringing the theoretical foot up and pushing it on beyond, and so on in unending alterations.” Robert A. -
Biography of Horace Welcome Babcock

P R ESTON Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 2007 NATIONAL ACADEMY OF SCIENCES WASHINGTON, D.C. Photograph by Mount Wilson and Los Campanas Observatories HORACE WELCOME BABCOCK September 13, 1912−August 29, 2003 BY GEORGE W . P RESTON ORACE BABCOCK’S CAREER at the Mount Wilson and Palomar H(later, Hale) Observatories spanned more than three decades. During the first 18 years, from 1946 to 1964, he pioneered the measurement of magnetic fields in stars more massive than the sun, produced a famously successful model of the 22-year cycle of solar activity, and invented important instruments and techniques that are employed throughout the world to this day. Upon assuming the directorship of the observatories, he devoted his last 14 years to creating one of the world’s premier astronomical observatories at Las Campanas in the foothills of the Chilean Andes. CHILDHOOD AND EDUCATION Horace Babcock was born in Pasadena, California, the only child of Harold and Mary Babcock. Harold met Horace’s mother, Mary Henderson, in Berkeley during his student days at the College of Electrical Engineering, University of California. After brief appointments as a laboratory assis- tant at the National Bureau of Standards in 1906 and as a physics teacher at the University of California, Berkeley, in 1907, Horace’s father was invited by George Ellery Hale in 1908 to join the staff of the Mount Wilson Observatory (MWO), where he remained for the rest of his career.
