Euresys Computer Platform
Euresys was the first company to introduce a computer platform based on the original Cyrix architecture. Since its introduction in 2000 the Cyros line allows software to run on hardware that was built to run software written based on the original Cyrix architecture. Since its original introduction in 2000 Euresys has been using the original Cyrix design and using many of the same modules available on the original Cyrix platform, but now using a platform designed for software developers who would not have the original design as they are based on the original designs with modules they develop.
The platform is a x86 architecture with 32 bit CPU, 1 megabyte of L3 cache, 1 megabyte of L2 cache, 8 megabytes of L2 cache, a 1 gigabyte of main memory, and 4. 5 megabytes of I/O space. The platform has two 32k flash ROM chips, 2 megabytes of ECC memory, and a 256k EEPROM chip. The X86 architecture has a total of 7 modules for the processor (5 microprocessors and 2 IO modules), memory (12K, 1K, 2K, and 1Mbytes), and IO (8K, 256K, and 1Kbytes) and an embedded platform. The embedded platform is based off of the AMD SoC and has a built in 8 MHz Clock for I/O. The original Cyrix architecture has a total of 4 modules for the CPU (3 Micro Processors and 1 IO Module), memory (4K, 512K, and 4 Megabytes), and IO (1. 2 Megabyte and 2Kbytes). The memory modules have 1Mbit of DIMM memory and have an 8 mega bit bus. The IO modules are for the X86 CPU and for the embedded platform which has 8 MHz Clock.
The architecture uses an L1 cache to reduce load on the CPU. The L1 cache is split into two 256 byte pages that are the top of the page is 4K bytes and the bottom of the page is 1K bytes. The CPU will cache instructions and data in these two 256 byte blocks. The L1 cache is shared with the CPU with 2. 5 Kbytes of ECC memory.
Measurement of the Geometric Parameters of Power Contact Wire Based on Binocular Stereovision.
Article Title: Measurement of the Geometric Parameters of Power Contact Wire Based on Binocular Stereovision | Computer Hardware.
A new approach to contact wire measurement is proposed which is based on the binocular stereopsis and the 3D reconstructed shape of the power contact wire. The reconstructed shape is obtained from a reconstructed 3D model of the power contact wire under a known viewing position. To estimate the viewing position, a single-point measurement method for contact wire is proposed. In this method, the position of the power contact wire is estimated by measuring the length of the power contact wire in the eye and then dividing that value by a predetermined factor for determining the viewing position. Because the above-mentioned measurements are performed by a single-point measurement method, the estimated viewing position does not have a positional accuracy sufficient to resolve the geometric parameters of the power contact wire. A new method for determining the viewing position is therefore proposed, which improves the positional accuracy. A geometric model of a power contact wire is constructed from the 3D reconstructed shape and the viewing position, and the viewing position is determined from the estimated viewing position by the measurement method based on the binocular stereopsis. The geometric model of a power contact wire is derived without the use of the power contact wire, and therefore it is not necessary to estimate the geometric parameters of the power contact wire. In other words, the method does not need to measure the power contact wire and construct a geometric model thereof. Therefore, the proposed method can perform a measurement without measuring the power contact wire.
It is well known that the measurement of the position of objects in the real world using only the visual sense is difficult. Because the human eye has a complex optical system that does not allow a single-point measurement, the position of objects on 2D or 3D spatial coordinates is difficult to measure. The same is true for the object’s shape and size on the screen. For example, in the field of digital photography, the position of the main subject of a photograph is difficult to measure. In the field of industrial applications, where the object is moving, the position of the object in real time is difficult to measure. In other words, it is impossible to measure the position of a moving object. Although a laser interferometer can measure a precise position, it is expensive and requires a large space.

The Electro-Mechanics of Drift Tube Wires at the Interface of Drilling Technology and Electric Power Transmission [by Takuya Umeda, Keiichi Ikeda, Hideyuki Murota] in Journal of Electro-Mechanical Engineering and Technology (J. Electro-Mechanical Eng’g & Tech.
A drift tube and a guide rail are electrically connected to each other so as to form a current transmission system. An electrode and an insulator are provided at both ends of the drift tube. The drift tube includes a closed-loop type circuit (1). A current is transmitted in a state in which the upper part is the drift tube and the lower part is the guide rail. Further, the drift tube has an elastic section having an elastic force of the same direction from the upper part to the lower part. By means of the current transmission structure to be described in more detail, transmission loss in an electric wave is minimized. By the current transmission structure described in the above example, a transmission loss caused by electro-migration in an oxide layer of the electrode can be reduced since electro-migration is taken into consideration.
Recently a technique for reducing the transmission loss in electric power by the use of a so-called conductive track or conductor by etching has attracted attention (1, 2). The technique is called as a conductive track or conductor technique (1).
Mechatronic design of a fast wire scanner for IHEP U-70 accelerator
A new scanner concept in a fast wire method of scanning, and its realization on a two-axis motion platform, has been developed at the Institute of High Energy Physics (IHEP) of Beijing. The scanner uses a new design for the beam-scanner, in which a flexible beam rod is held by a rotating frame (the frame is moved in the X-, Y- and Z-axis) of a single mass using a servomotor. An electromagnetic torque sensor has been designed to precisely control the angular position of the frame and the position and orientation of the beam rod. The scanner requires a high beam intensity in order to avoid the beam attenuation inside the scanner. Mechatronic and physical processes of a rotating frame and a beam rod were implemented in a new system; first, the frame’s angular position or the position and orientation of the beam rod were varied to move the beam position and orienting axis. It should be noted that a conventional control system for a single-mass scanner does not have enough accuracy for a higher beam intensity. By using the servomotor and a magnetically variable linear encoder, the position and orientation of the beam rod can be changed with high accuracy for different beam positions. It will be important to obtain an accurate beam position and orientation while using a flexible beam holder to ensure the positioning of the beam rod. The proposed frame was designed to be capable of maintaining a large angle between the two axes. Thus, this new scanner is expected to have a large and stable beam intensity. The scanner’s performance will be evaluated by the experimental studies carried out on IHEP U-70.
