T he move from Windows XP to Windows 7 is a dramatic one and the installation process is slightly more involved than when upgrading from Vista to Windows 7. This is because it is not possible to upgrade Windows XP in the same way – Windows 7 can usually still be installed on the computer (assuming the PC meets the hardware requirements – see page 14), but a ‘clean’ installation must be performed. Going down this route means you will need to back up files and settings to avoid losing all your important data or having to spend a great deal of time configuring Windows 7. Thankfully, this does not have to be done completely manually, as the Easy Transfer Wizard is on hand to help. Read on to find out how to upgrade from Windows XP to Windows 7. AS THE PROCESS OF PERFORMING A CLEAN INSTALLATION of Windows 7 will completely wipe the hard disk, it is vitally important to create a backup of any files and settings that need to be kept. Files stored in the My Documents folder can be backed up by copying them to an external hard disk or by burning them to blank CDs or DVDs, but you will also have to work through each of the programs you have installed to see whether it is possible to back up any settings that are in place – this includes backing up messages in your email program. There is often an ‘export’ option available that can be used to save data to another location.
Before committing to an upgrade, I suggest you read my “BUYING A WINDOWS 7 PC” sheet. There are lots of thoughts and comments there regarding the PC hardware. Many PC’s with XP Pre-installed were marketed as “Vista Ready”. They may not be capable of running Windows 7 (or Vista). (Blame Microsoft for that). Run the Upgrade Advisor Tool to find out. In most cases, PC’s sold with Windows VISTA pre-installed should be easily upgradable to Windows 7. They will run faster if you do. My personal recommendation is to never do an upgrade from Vista, but to migrate from Vista to Windows 7 by doing a clean Windows 7 install. You can use the Easy Transfer Tool to move your data and settings. If your PC is currently running Windows XP, then buying a whole new Windows 7 PC is usually a better bet than upgrading your old PC. See my comments in a later section of this sheet. CPU: If you plan to install Windows 7 64-bit, make sure your CPU can support 64-bit operation. You can run the “SecurAble” utility to find out. From http://www.grc.com/securable.htm . HARD-DRIVE SPACE: Make sure you have plenty of extra hard-drive space. A typical Windows 7 system with a few programs can easily exceed 25-30 GB. WARNING: If you do a full Windows 7 install and do not tell the Windows 7 Installer to format the drive, then all of your old system files and all of your new system files will all be using space the hard-drive. Do you have room for that? SSD’s (Solid State Hard Drives): Windows 7 runs like lightning with a SSD main-drive. If you plan to go to an SSD, I recommend upgrading to the SSD at the same time you upgrade to Windows 7. See more about SSD’s in my “BUYING A WINDOWS 7 PC” sheet. NOTE: Your PC's BIOS must support "ahci" SATA control to use an SSD. DEVICE DRIVERS: Even if the Upgrade Advisor says all is OK, you should go to the Manufacturer’s website for every one of your external devices (Printers, scanners, cell phones, cameras, etc ) and make sure they offer drivers for their gear for the version of Windows 7 you...
HP Notebook PCs - Upgrading from Windows 7 to Windows 8 This document pertains to HP Notebook computers to be upgraded from Windows 7 using a digital copy of Windows 8. You may perform either an In-place Installation that retains your data and settings from Windows 7, or a Clean Installation (custom) that deletes all data from the hard drive before installing Windows 8. Please read the following important information before beginning your upgrade: Not all Windows 8 features may be available on all Windows 7 computers. Your computer may require additional hardware, software, firmware, and/or a BIOS upgrade to install and run Windows 8. HP provides upgrade instructions and drivers for most computers sold after October 1st, 2011. For information about the Microsoft Windows 8 Upgrade Offer go to www.windowsupgradeoffer.com and www.windowsupgradeoffer.com/enUS/Home/Faq. Check these sites frequently, as some details may change and/or additional information may become available.
In an effort to keep consumers more informed about the reliability of the products they buy, over the past year and a half, SquareTrade has taken a look at the failure rates of many types and brands of laptops, cell phones, and game consoles. This time we turn our attention to digital cameras. In this reliability report, SquareTrade examines digital camera reliability from a few different angles. We start with an overview of digital camera failures, both from manufacturer defects and accidents. We then compare camera reliability by brand and price point. This analysis examines customer reported failure data from a sample of over 60,000 new digital cameras purchased by SquareTrade warranty customers (see Appendix for sample details). SquareTrade offers warranty plans that cover accidental damage as well as hardware failures, and we consider malfunctions from normal usage (“malfunctions”) separate from accidents (“accidents”) in our analysis. We refer to “total failure rate” as the sum of failure rates due to malfunctions and accidents. Among our conclusions, we found that almost 11% of digital cameras fail over the first 2 years of ownership, with 6.6% of failures coming from malfunctions and 4.1% from accidents. We also found the least expensive point-and-shoot digital cameras to be the least reliable, while expensive DSLR cameras tended to be the most reliable. This correlation between price and reliability was also found in SquareTrade’s earlier research on laptop computers as well. When we break the reported malfunction analysis down by brand and price, Panasonic clearly emerges as the most reliable brand of point-and-shoots. For example, on inexpensive point-and-shoot cameras, Panasonic had a malfunction rate of just 5.3% over the first 2 years. On the opposite end of the spectrum are Casio and Polaroid, with 2 year malfunction rates of 13.0% and 11.9% respectively. Now let’s delve into the data and take a look at the numbers. Please note that this study only includes digital cameras. Whenever we use the word camera, we are only referring to digital cameras.

Many process plants have an outdated Distributed Control System (DCS) currently in place. As a DCS reaches the end of its useful life, an upgrade to a new automation system is required. One of the main factors determining when to upgrade is the expected superior performance of a new automation system as compared to the old DCS. Superior performance results in lower overall plant operating costs, less downtime and lower maintenance costs—providing sufficient return on investment to justify an upgrade. This white paper will focus on the specific ways in which a new automation system can deliver superior performance as compared to a typical older DCS. Areas that will be covered include but aren’t limited to Advanced Process Control, integration with other manufacturing-related software and hardware systems, remote access, data analysis, PID loop control, and alarm and event handling. For each of these areas, this white paper will show why a new automation system is better than an older DCS. End users should expect much more from their new automation system than from their old DCS, and this white paper will show them how to fulfill those expectations, thereby justifying the decision to upgrade from an old DCS to a new automation system. Superior Performance A new automation system will outperform an older DCS in a variety of ways as listed in Table 1, and as discussed below. One of the main advantages will be superior process control, which confers a number of benefits. Table 1: Advantages of New Automation System over Older DCS Superior PID loop control and auto tuning Improved Advanced Process Control Improved alarm and event handling More reporting options with easier implementation Easier integration with third-party software systems Easier integration with smart instruments, analyzers and valves Better remote access Lower support costs Better access to new features and functions Easier to find personnel familiar with the system...
This paper presents a three-step process for creating locally optimal distributed controls for multiple robot vehicles. The first step is to define a global performance index whose extremum produces a desired cooperative result. The second step is to partition and eliminate terms in the performance index so that only terms of local neighbors are included. This step minimizes communication amongst robots and improves system robustness. Rather than requiring every robot to know the position of all the other robots, each robot only needs to know the position of its nearest neighbors. Also, if a neighbor dies, a new set of nearest neighbors is selected from the remaining robots. The third step is to define a control law that is the gradient of the partitioned performance index. This control drives the system towards the local extremum of the partitioned performance index. Connective stability of the resulting controls can be proven with a vector Liapunov technique. The approach has been tested in simulation and robotics hardware on a number of test problems. The first problem is the distribution of multiple robots along a line or curve. The second and third problems are the distribution of multiple robots in an unconstrained and constrained twodimensional plane. The fourth problem is the distribution of multiple robots around an elliptical curve. The fifth problem is for multiple robots to converge on the source of a plume in a plane. The sixth problem is for multiple underwater robots to converge on the source of a plume in a 3D volume.
