  • The theory of switched systems concerns hybrid dynamical systems composed of a family of continuous–time subsystems and a switching law, orchestrating switching between these subsystems. Systems of this class have been identified in many natural and man– made systems, and are recently widely studied by control theorists, computer scientists, practicing engineers and others.

  • The “Ericsson GSM System” is Ericsson’s implementation of the Global System for Mobile Communications (GSM), encompassing GSM 900, GSM 1800, and also a GSM 1900 standard for the North American market. These systems are built around Ericsson´s AXE switching system technology. AXE’s system modularity standard allows functions to be added, deleted, or modified without disturbing the functionality in the rest of the system. Thus creating an environment where Ericsson’s GSM system can profit fully from future AXE developments....

  • LAN and Ethernet switches are usually considered as plumbing. They are easy to install and configure, but it is easy to forget about security when things appear to be simple. Multiple vulnerabilities exist in Ethernet switches. Attack tools to exploit them started to appear a couple of years ago (for example, the well-known dsniff package). By using those attack tools, a hacker can defeat the security myth of a switch, which incorrectly states that sniffing and packet interception are impossible with a switch.

  • GSM (Global System for Mobile Communications, originally Groupe Spécial Mobile), is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe technologies for second generation (2G) digital cellular networks. Developed as a replacement for first generation (1G) analog cellular networks, the GSM standard originally described a digital, circuit switched network optimized for full duplex voice telephony.

  • 1. STEPPER MOTOR SYSTEMS OVERVIEW Motion Control, in electronic terms, means to accurately control the movement of an object based on either speed, distance, load, inertia or a combination of all these factors. There are numerous types of motion control systems, including; Stepper Motor, Linear Step Motor, DC Brush, Brushless, Servo, Brushless Servo and more. This document will concentrate on Step Motor technology. In Theory, a Stepper motor is a marvel in simplicity. It has no brushes, or contacts.

  • Why is it so hard to make lasting changes in our companies, in our communities, and in our own lives? The primary obstacle is a conflict that’s built into our brains, say Chip and Dan Heath, authors of the critically acclaimed bestseller Made to Stick. Psychologists have discovered that our minds are ruled by two different systems—the rational mind and the emotional mind—that compete for control. The rational mind wants a great beach body; the emotional mind wants that Oreo cookie.
