  • Hydrogen: The Key to an Emission-Free Future?
    Hydrogen technology plays a key role on the way to the desired climate neutrality. Hydrogen is considered the energy carrier of the future and is an important building block for the decarbonization of industry. Michael Leitsch, Head of Opportunity Engineering at AERZEN, on the potential of green
  • Analogue IC Design: The Current-Mode Approach
    Analogue IC Design: The Current-Mode Approach. This book draws upon contributions from the world's most eminent analogue IC designers to discuss the "true" complementary bipolar process, CMOS VLSI technology, and gallium arsenide processing, with key building blocks, circuit designs
  • EETimes.com | Electronics Industry News for EEs & Engineering Managers
    TI to reinforce consumer electronics center in Japan Texas Instruments Inc. is targeting consumer electronics as a key growth market. Digital camera forecast raised for 2003 The sizzling growth of the digital camera market has prompted one researcher to raise its forecast for the product segment
  • Winning the Space Race
    step. First, the team created an L27 orthogonal array design. The design was constructed in nine blocks, one for each different raw material blend. Within each block, the different process parameters were varied. Two of the trials were repeated, for a total of 29 trials. Each of these trials produced
  • What an Executive Order for Improved Chemical Facility Safety Means for Emergency Valve & Actuator Applications
    The installation of emergency block valves (EBV) on process piping and equipment is a key component of the various layers of protection. EBVs are used to shut down the system in the event of an emergency; and remotely operated EBVs are an acceptable loss prevention practice for reducing the size
  • Know Your Stormwater Risks and Avoid Violations
    Nobody wants to harm the environment, let alone get popped with a violation. That's why New Pig develops practical solutions to protect your storm drains. Our team of stormwater experts has visited hundreds of facilities and zeroed in on key products that filter, block and absorb pollutants. See
  • Monitoring Effects of Sympathicolysis with Infrared-Thermography in Patients with Complex Regional Pain Syndromes (CRPS) (.pdf)
    Determining pain intensity is a key intention in pain management. Unfortunately, no tool has been developed to date, that sufficiently fulfils this task, hence, it is extremely complex to conclude, if treatment offered to a patient is helpful or not. In particular forms of pain, i.e. neuropathic
  • Application Requirements Drive Choice of Voltage Regulator in Portable Systems
    . The growing use of multi-voltage designs has further complicated the designer's task. Many of the new function blocks designers are introducing into portable devices do not operate at the same voltage as the system power source. For example, the typical single cell lithium-ion battery powering a cell phone

    RC is an iterative secret- key block cipher published by Rivest [] in .
  • Encyclopedia of Cryptography and Security
    MAC Session Key The MAC Session Key KS either consists of only a leftmost key block KS = KSL or the concatenation of a leftmost and a rightmost .
  • Fast Software Encryption
    Inspired by [16], we note that APE can also be described as a block cipher based design: we drop the key additions at the beginning and end, and replace the permutations with a keyed block cipher EK defined by EK := KpK := ⊕0 …
  • Fast Software Encryption
    Many hash functions based on a fixed- key block cipher (also called permutation based hash functions) have also been proposed [32,43,48].
  • Advances in Cryptology – CRYPTO 2013
    For k-bit keys block ciphers, the resistance to dif- ferential cryptanalysis means p−Br max > 2k , which gives a criteria on r and pmax for the security of the cipher.
  • The key‐group method
    Abstract This paper proposes an extension to the key‐block method, called ‘key‐group method’, that considers not only individual key blocks but also groups of collapsable blocks into an iterative and progressive analysis of the stability of discontinuous rock slopes.
  • Cryptographic systems
    Differently however. by synchronization errors: As the pseudozufällige current of " key blocks enc(k,ai−1) independently of the processing of " the plaintext or key text blocks is generated, all following blocks are distorted until recovery of synchronization .
  • Fast Software Encryption
    the block cipher size is n bits and the compression function output size is 2n), from simple- key block ciphers such as AES-128 or double-key such as AES-256 [11].
