3000AD Systems PDF-eXPLODE v4.1.26.97.42307
PDF-eXPLODE, an electronic document bursting or report bursting tool, makes it easy and cost-effective for small businesses to get their customers’ invoicing, vendors’ remittances and employee payslip information to the relevant people on time. It will definitely save you heaps of money.
The following instruction sums up the document or report bursting and delivery process in PDF-eXPLODE:
Step 1: Click PRINT from within your application – Select the PDF-eXPLODE Printer. Windows processes the output and sends this to PDF-eXPLODE
Step 2: PDF-eXPLODE now create a PDF (referred to as ‘Master PDF’) which contains all pages of the output from Windows
Step 3: Explode the Master PDF – Here is where the report bursting occurs: PDF-eXPLODE will ‘explode’ the PDF into multiple PDFs each containing one or more pages based on hidden "tag” (specially formatted text) in the document
Step 4: Deliver bursted/exploded PDF documents by E-Mail or FTP (or just archive on your hard disk) with or without additional documents attached (based on rules defined by you)
It’s as easy as 1-2-3-4!!

Rizom-Lab Unfold3D 2018.0.1
Since its creation in 2003 by Remi Arquier, Unfold3D was one of the first commercial software capable of automatically flattening 3D mesh geometries as the same time as preventing from stretching and distortion. Then, it rapidly found its place in the computer graphic industry while being adopted by many freelancers and major studios out there. Also, its core algorithms are now integrated in standard into Autodesk Maya. Today, following the path towards an ideal tool set capable of segmenting, flattening and packing UVs without any manual intervention, Rizom-Lab focuses on enhancing our technology, and making it available to 3D artists and product designers.

Paolo Rugarli - Steel Connection Analysis
Wiley-Blackwell, 2018
pdf, 537 pages, english
ISBN: 978-1-119-30346-6
Steel connection analysis and checking is one of the most complex problems in structural engineering, and even though we use very powerful computing tools, it is still generally done using very simplistic approaches. Fromthe point of view of a typical structural engineer, the problem to solve is to design and check nodes, not single connections, i.e. a number of connections between a number of different members – maybe tens or even hundreds of load combinations, inclined member axes, and generic stress states. In a typical 3D structure there may be several tens of such nodes, or maybe even hundreds, which may be similar, or may be different from one another; identifying nodes that are equal is one of the problems that the designer has to face in order to reduce the number of different possible solutions, and in order to get a rational design. However, this problem of detecting equal nodes has not been sufficiently researched, and there are currently no tools that are able to properly solve this issue. If posed with the due generality, the problem of checking 3D nodes of real structures has not been solved by automatic computing tools. Also, because a general method of tackling all these problems is apparently still lacking, usually a few "cooking recipes” have been used to solve a limited number of typical, recurring (2D assimilated) nodes. Indeed, it often happens that true, real world nodes have to be analyzed by such recipes, despite the fact that the basic hypotheses needed to apply these recipes do not always hold true. This poses a serious problem because although these "cooking recipes” have been widely used, in the past few years they have been applied to 3D structures designed using computer tools, in the non-linear range, perhaps in seismic areas, and with the aim of reducing the weight of steel. The effects of such oversimplification have already been seen in many structures where steel connections have failed, especially in seismic areas (e.g. Booth 2014), but even in non-seismic areas (e.g. White et al. 2013, Bruneau et al. 2011). Generally speaking, it is well known that connections are one of the most likely points of weakness of steel structures, one of the most cumbersome to design – indeed one of the least designed – and one of the least software-covered in structural engineering. |

Shenglai Yang - Fundamentals of Petrophysics Second Edition
Springer Geophysics, 2017
pdf, 509 pages, english
ISBN 978-3-662-55028-1
This book presents fundamental physical and physicochemical knowledge involved in oil and gas development engineering, such as physical and chemical phenomena, physical process. It is arranged to provide the knowledge of porous rock properties of reservoir rocks, and properties of fluids, i.e., gases, hydrocarbon liquids, and aqueous solutions, and the mechanism of multiphase fluid flow in porous media. The book also brings together the application of the above theories and knowledge. This textbook is written to serve the undergraduate teaching of the petroleum engineering major. It focuses on the introduction of basic conceptions, terms, definitions, and theories, placing more emphasis on the width of knowledge rather than the depth. What should be learned through the course includes the definitions of some essential physical parameters, the physical process, important physical phenomena, influencing factors, and engineering applications. In addition, the measuring methods and experimental procedures for the key parameters are also included. Through the study of this book, good foundation of knowledge frame for petroleum engineering should be established for students, which is benefit for both their further studying and their work in the future when they are engaged in job. |

Artsoft Gearotic v3.03
Gearotic is a CAD/CAM 3D software package aimed to assist with your geared mechanical creations. It was primarily designed as a gear template generator, but developed into a utility package we hope you'll find useful. Gearotic will generate gears individually or combine them to create a moving gear train. Software allows you to simulate, animate, create toolpaths for cnc mode or export as 3D models. Gearotic has grown a great deal over the past few years. It is now not only a gear template generator, but can create objects for 3d printing, design clock escapements, tabbed boxing, circular and non circular gears and even Celtic Knots. We hope you enjoy the new and added functions of Gearotic. It continues to grow and have features added and upgraded at users request. We consider it an adjunct to CAD programs of all types and hope it helps you in your design work. It is our hope that G2 will allow what in the past could be done by dedicated hobbiests to be done by the more casual hobbiest. Gearotic is written by Art Fenerty, the original creator of the Mach series of machine controllers. It is supported by Art , and by Bob Landry, a fellow Gearhead. So whether your interest is in clockworks, window openers, whirlygigs or rube-goldberg machines, we hope you find a comfortable spot to meet and discuss such things. Gearotic is more of an interest group than a normal software company, as with Mach3 the program grows around the community of its users. |
