Virtual Memory
Chapter 4 Virtual Memory Linux processes execute in a virtual environment that makes it appear as if each process had the entire address space of the CPU available to itself. This virtual address space extends from address 0 all the way to the maximum address. On a 32-bit platform, such as IA-32, the maximum address is 232 − 1or0xffffffff. On a 64-bit platform, such as IA-64, this is 264 − 1or0xffffffffffffffff. While it is obviously convenient for a process to be able to access such a huge ad- dress space, there are really three distinct, but equally important, reasons for using virtual memory. 1. Resource virtualization. On a system with virtual memory, a process does not have to concern itself with the details of how much physical memory is available or which physical memory locations are already in use by some other process. In other words, virtual memory takes a limited physical resource (physical memory) and turns it into an infinite, or at least an abundant, resource (virtual memory). 2. Information isolation. Because each process runs in its own address space, it is not possible for one process to read data that belongs to another process. This improves security because it reduces the risk of one process being able to spy on another pro- cess and, e.g., steal a password. 3. Fault isolation. Processes with their own virtual address spaces cannot overwrite each other’s memory. This greatly reduces the risk of a failure in one process trig- gering a failure in another process. That is, when a process crashes, the problem is generally limited to that process alone and does not cause the entire machine to go down. -

Solid Truss to Shell Numerical Homogenization of Prefabricated Composite Slabs
materials Article Solid Truss to Shell Numerical Homogenization of Prefabricated Composite Slabs Natalia Staszak 1, Tomasz Garbowski 2 and Anna Szymczak-Graczyk 3,* 1 Research and Development Department, FEMat Sp. z o. o., Romana Maya 1, 61-371 Pozna´n,Poland; [email protected] 2 Department of Biosystems Engineering, Poznan University of Life Sciences, Wojska Polskiego 50, 60-627 Pozna´n,Poland; [email protected] 3 Department of Construction and Geoengineering, Poznan University of Life Sciences, Pi ˛atkowska94 E, 60-649 Pozna´n,Poland * Correspondence: [email protected] Abstract: The need for quick and easy deflection calculations of various prefabricated slabs causes simplified procedures and numerical tools to be used more often. Modelling of full 3D finite element (FE) geometry of such plates is not only uneconomical but often requires the use of complex software and advanced numerical knowledge. Therefore, numerical homogenization is an excellent tool, which can be easily employed to simplify a model, especially when accurate modelling is not necessary. Homogenization allows for simplifying a computational model and replacing a complicated composite structure with a homogeneous plate. Here, a numerical homogenization method based on strain energy equivalence is derived. Based on the method proposed, the structure of the prefabricated concrete slabs reinforced with steel spatial trusses is homogenized to a single plate element with an effective stiffness. There is a complete equivalence between the full 3D FE model built with solid elements combined with truss structural elements and the simplified Citation: Staszak, N.; Garbowski, T.; Szymczak-Graczyk, A.

Solaris 10 End of Life
Solaris 10 end of life Continue Oracle Solaris 10 has had an amazing OS update, including ground features such as zones (Solaris containers), FSS, Services, Dynamic Tracking (against live production operating systems without impact), and logical domains. These features have been imitated in the market (imitation is the best form of flattery!) like all good things, they have to come to an end. Sun Microsystems was acquired by Oracle and eventually, the largest OS known to the industry, needs to be updated. Oracle has set a retirement date of January 2021. Oracle indicated that Solaris 10 systems would need to raise support costs. Oracle has never provided migratory tools to facilitate migration from Solaris 10 to Solaris 11, so migration to Solaris has been slow. In September 2019, Oracle decided that extended support for Solaris 10 without an additional financial penalty would be delayed until 2024! Well its March 1 is just a reminder that Oracle Solaris 10 is getting the end of life regarding support if you accept extended support from Oracle. Combined with the fact gdpR should take effect on May 25, 2018 you want to make sure that you are either upgraded to Solaris 11.3 or have taken extended support to obtain any patches for security issues.

Bridge Types in NSW Historical Overviews 2006
Timber Truss Bridges Study of Relative Heritage Significance of All Timber Truss Road Bridges in NSW 1998 25 Historical Overview of Bridge Types in NSW: Extract from the Study of Relative Heritage Significance of all Timber Truss Road Bridges in NSW HISTORY OF TIMBER TRUSS BRIDGES IN NSW 1.1 GENERAL During the first fifty years of the colony of New South Wales, 1788 - 1838, settlement was confined to the narrow coastal strip between the Pacific Ocean and the Great Dividing Range. The scattered communities were well served by ships plying the east coast and its many navigable rivers. Figure 1.1a: Settlement of early colonial NSW. Shaded areas are settled. In Governor Macquarie's time between 1810-1822, a number of good roads were built, but despite his efforts and those of the subsequent Governors Darling and Bourke, and of road builders George Evans, William Cox and Thomas Mitchell, the road system and its associated bridges could only be described as primitive. Many roads and bridges were financed through public subscriptions or as private ventures, particularly where tolls could be levied. The first significant improvement to this situation occurred in late 1832 when Surveyor- General Mitchell observed a competent stone mason working on a wall in front of the Legislative Council Chambers in Macquarie Street. It was David LennoxR3. He was appointed Sub-Inspector of Roads on October 1, 1832 then Superintendent of Bridges on June 6, 1833. His first project was to span a gully for the newly formed Mitchell's Pass on the eastern side of the Blue Mountains. -
Learning the Methods of Engineering Analysis Using Case Studies, Excel and VBA - Course Design
Computers in Education, Session 1520 Learning the Methods of Engineering Analysis Using Case Studies, Excel and VBA - Course Design Michael A. Collura, Bouzid Aliane, Samuel Daniels, Jean Nocito-Gobel School of Engineering & Applied Science, University of New Haven Abstract Methods of Engineering Analysis, EAS 112, is a first year course in which engineering and applied science students learn how to apply a variety of computer analysis methods. The course uses a “problem-driven” approach in which case studies of typical engineering and science problems become the arena in which these analytical methods must be applied. A common spreadsheet program, such as Microsoft Excel, is the starting point to teach such topics as descriptive statistics, regression, interpolation, integration and solving sets of algebraic, differential and finite difference equations. Students are also introduced to programming fundamentals in the Visual Basic for Applications environment as they create the algorithms needed for the analysis. In this programming environment students gain an understanding of basic programming concepts, such as data types, assignment and conditional statements, logical and numerical functions, program flow control, passing parameters/returning values with functions and working with arrays. EAS 112 is a stop along the Multidisciplinary Engineering Foundation Spiral1 in the engineering programs at the University of New Haven. A typical student will take the course in the second semester of the first year. Certain engineering foundation topics will appear in the assigned problems and case studies, contributing to students’ understanding of areas such as electrical circuits, mass balances, and structural mechanics. At this point along the spiral curriculum students are given most of the equations needed to analyze the case study problems, but they are responsible for development of the algorithms and implementing these in the spreadsheet and/or programming environment. -
