D Cube R2 Software Engineering
I'm solving by 4x4 Rubik's cube (aka Rubik's revenge) by reducing it to a 3x3. However, I keep finding that once I've got all the edge pieces paired together I've accidentally moved the centre pieces around, so that they're in places that don't correspond to their positions on a 3x3 cube.To solve this, I need algorithms to do the following two things:.swap two opposite centres.swap two adjacent centresThe first is fairly easy to find online but the second is what I really need. (I'm asking for both so that future visitors will have both in one place.)I don't need the algorithm to leave the edge or corner pieces invariant, as long as it doesn't split up the edge pieces that I've already paired.
Opposite Centers:To swap two opposite centers (top and bottom) without moving the corners nor egdes, you can use: r2 U2 r2 U2 M2 U2 l2 U2 l2If you don't like Cube notations (like me), here the same algorithm with symbols instead:Here a shorter alternative with the same result (pure top and bottom): r2 S2 r2 S2Adjacent Centers:To swap two adjacent centers (this time it will move around some edges and corners), you can use: r U2 r' l' U2 lWhich will swap the two adjacent centers at the top and front, as well as the FD, FU, FB edges.I will see if I can find a pure swap as well. Will edit when I do.Here a pure adjacent center swap, for the front and left faces: u M2 u' L2 F2 u M2 u' M2 F2 LM2Or here a shorter alternative adjacent center swap, for the front and right faces: u M' U2 M u' d' M U2 M' dShorter opposite swap and both pure adjacent swaps were not found by me, but.

Whether for protection of assets, personnel or monitoring the operations of a manufacturing facility, intelligent IP-based video surveillance provides features and capabilities well beyond traditional analog camera systems.With the development of megapixel video cameras, image quality and resolution has taken a major leap forward that allows for fewer cameras capturing more information that can be analyzed in more detail than was ever available from analog systems. Features such as electronic pan, tilt and zoom (PTZ) replace the need for expensive mechanically driven cameras of the past. Instead of scanning an area with an analog camera, a multi-lens megapixel camera can capture the entire 180 or 360 degree panorama dramatically increasing the surveillance data for live view or after-the-fact analysis.As with any technology, the design, installation and configuration of the IP video network is critical to its performance and reliability.
All aspects of the system from camera resolution to lens selection as well as storage systems and software must be designed to provide the best possible solution for the user. DCT’s technical staff works with each customer from design to implementation and on-going support to provide a cost effective, single source solution.

From conducting business more efficiently to enhancing the patient experience to increasing access to educational resources campus-wide, indoor wireless service is a must have in today’s fast paced wireless world.To some, “wireless” equates to Wi-Fi enabled laptops, but it’s much more than that - the world today relies on mobile and smart phones, BlackBerry devices, PDAs, and two-way radios to communicate. Your employees, customers, clients, students, patients or guests need ALL these wireless tools to work - especially indoors!In many organizations, mobile phones, Blackberry and other mobile devices are the primary means of communication for both voice and data applications. When these devices are used inside a building, however, materials such as concrete and steel weaken signals.

Our goal is to help your company deploy a wireless network that will grow with your business in the future.WiFi / WLAN Network Design / EngineeringDeployment of a wireless network requires careful planning. Business requirements and objectives need to be evaluated and a site survey must be undertaken to determine possible sources of interference. WiFi Networks can be tricky to implement in high interference areas, be incompatible with existing equipment and can open up security risks. WLANs are best used in addition to - rather than a replacement to wired networks. Our engineers will assure proper planning when designing and implementing your wireless network.
The complexity of your network will vary depending on the obstacles within and the size of your facility.Site SurveysA site survey is always performed first. This is a physical survey of the customer's premises to locate the best possible places to install access points and ensure 100% wireless coverage and optimum performance.Before installing any wireless devices we perform a radio frequency (RF) test in order to better understand the behavior of radio waves within a facility. This is recommended because various obstacles such as doors, walls, elevator shafts and people might affect the radio frequency pattern, causing it to be irregular and unpredictable.
Even if you are using omni-directional antennas, radio waves do not travel the same distance in all directions. The RF test can also detect any radio interference that might come from other sources and could affect the performance of the wireless LAN negatively. The ultimate goal of the site survey and RF test is to help determine the number and placement of the access points.Access Points - WLAN InstallationDCT will integrate the WiFi system into your current network as well as install all the required wireless equipment and certify its operation.
