HAL/S-360 compiler system specification
A three phase language compiler is described which produces IBM 360/370 compatible object modules and a set of simulation tables to aid in run time verification. A link edit step augments the standard OS linkage editor. A comprehensive run time system and library provide the HAL/S operating environment, error handling, a pseudo real time executive, and an extensive set of mathematical, conversion, I/O, and diagnostic routines. The specifications of the information flow and content for this system are also considered
HyperImage – Image-Oriented e-Science Networks
Images are an important source of scientific knowledge in many disciplines. E.g. you want to analyse satellite photographs or x-ray images of human livers or symbols of death in Dutch baroque paintings. You study the relevant images closely and compare details of one image with details of another. When you want to share your knowledge you will necessarily also communicate about image details. Using paper images, you can just mark up details of interest with a pencil. But with digital images you either have to make marks by employing an image manipulation software, which is not as widespread and easy to use as current text processing software is. Or you have to describe your findings verbally, such as "... above left is an interesting dark spot in picture No. 1 ... now compare it to picture No. 2 where a similar dark spot can be found nearly in the centre of the picture ..." and so on. Neither the employment of a complex image manipulation software package nor the time consuming and not very precise verbal description is satisfactory and appropriate for everyday use in science. Additionally, any technical solution to the lack of easy-to-use technology has to be Web-based in order to support collaborative research on images. The HyperImage project is concerned with the currently unsolved technical problem of establishing links between image details. Our goal is to develop a Web-based workspace that will enable scientists in any image-oriented discipline to create simple and precise links between images and image details, in a fashion similar to that which until now has been the privilege of text. The HyperImage editor permits scientists to mark details of pictures and create links between images and image details of any scale. It is programmed as a platform independent Java application and is open source (GNU Lesser General Public Licence). Any work in progress can be stored within the Hyper- Image system by an author or group of authors, or it can be exported as XML for further usage outside the HyperImage system. Currently we are testing our software prototype with our HyperImage partners from the faculties of Art History and Biology
Ambience: An Introduction
With this issue of Moveable Type, we hope to set in motion a new wave of interest in ambient literature, seeking new insight into the patterns and thematics of ambient writing and bringing to light discussions left unresolved by various critiques of ambience. Our issue theme of Ambience presents a conversation between a group of scholars, writers and reviewers who locate ambient literatures beyond apps and web browsers, identify new research trajectories, and challenge definitions of ambient literature, countering its contemporariness and reliance on technology by foregrounding precursors to ambient literature. We suggest that these developments be considered beyond a distraction or aberrant offshoot of book history; as contiguous with historic reader response practice; and that they may come to be an important component or even central element of composition and reception
An Edgeworth expansion for finite population L-statistics
In this paper, we consider the one-term Edgeworth expansion for finite
population L-statistics. We provide an explicit formula for the Edgeworth
correction term and give sufficient conditions for the validity of the
expansion which are expressed in terms of the weight function that defines the
statistics and moment conditions.Comment: 14 pages. Minor revisions. Some explanatory comments and a numerical
example were added. Lith. Math. J. (to appear
Drainage water quality impacts of agricultural management practices
Investigators analyzed the impacts of liquid swine manure application, tillage, rotation and cover crops on dissolved nutrient loss in subsurface drainage. The project took place at the ISU Northeast Research Farm near Nashua. Tile drainage water samples were collected weekly for nitrate and dissolved-reactive P analysis during 2009 and 2010. Nitrate-N concentrations were highest under continuous corn receiving swine manure every year compared to other treatments. Corn-soybean rotations that received manure only before corn had lower nitrate-N concentrations compared to corn-soybean rotations that received manure before both crops. During these three years, which were not ideal for cover crop growth due to cold wet springs, nitrate concentrations in tile water from the corn-soybean system without a cover crop were similar to or slightly higher than concentrations from the corn-soybean system with a cover crop
