Software Product Description and Quickspecs
VSI OpenVMS Alpha Version 8.4-2L2 Operating System DO-DVASPQ-01A Software Product Description and QuickSpecs PRODUCT NAME: VSI OpenVMS Alpha Version 8.4-2L2 DO-DVASPQ-01A This SPD and QuickSpecs describes the VSI OpenVMS Alpha Performance Release Operating System software, Version 8.4-2L2 (hereafter referred to as VSI OpenVMS Alpha V8.4-2L2). DESCRIPTION OpenVMS is a general purpose, multiuser operating system that runs in both production and development environments. VSI OpenVMS Alpha Version 8.4-2L2 is the latest release of the OpenVMS Alpha computing environment by VMS Software, Inc (VSI). VSI OpenVMS Alpha V8.4-2L2 is compiled to take advantage of architectural features such as byte and word memory reference instructions, and floating-point improvements, which are available only in HPE AlphaServer EV6 or later processors. This optimized release improves performance by taking advantage of faster hardware-based instructions that were previously emulated in software. NOTE: VSI OpenVMS Alpha V8.4-2L2 does not work on, and is not supported on, HPE AlphaServer pre-EV6 systems. OpenVMS Alpha supports HPE’s AlphaServer series computers. OpenVMS software supports industry standards, facilitating application portability and interoperability. OpenVMS provides symmetric multiprocessing (SMP) support for multiprocessing systems. The OpenVMS operating system can be tuned to perform well in a wide variety of environments. This includes combinations of compute-intensive, I/O-intensive, client/server, real-time, and other environments. Actual system performance depends on the type of computer, available physical memory, and the number and type of active disk and tape drives. The OpenVMS operating system has well-integrated networking, distributed computing, client/server, windowing, multi-processing, and authentication capabilities. -
Bit & Baud Rate
What’s The Difference Between Bit Rate And Baud Rate? Apr. 27, 2012 Lou Frenzel | Electronic Design Serial-data speed is usually stated in terms of bit rate. However, another oft- quoted measure of speed is baud rate. Though the two aren’t the same, similarities exist under some circumstances. This tutorial will make the difference clear. Table Of Contents Background Bit Rate Overhead Baud Rate Multilevel Modulation Why Multiple Bits Per Baud? Baud Rate Examples References Background Most data communications over networks occurs via serial-data transmission. Data bits transmit one at a time over some communications channel, such as a cable or a wireless path. Figure 1 typifies the digital-bit pattern from a computer or some other digital circuit. This data signal is often called the baseband signal. The data switches between two voltage levels, such as +3 V for a binary 1 and +0.2 V for a binary 0. Other binary levels are also used. In the non-return-to-zero (NRZ) format (Fig. 1, again), the signal never goes to zero as like that of return- to-zero (RZ) formatted signals. 1. Non-return to zero (NRZ) is the most common binary data format. Data rate is indicated in bits per second (bits/s). Bit Rate The speed of the data is expressed in bits per second (bits/s or bps). The data rate R is a function of the duration of the bit or bit time (TB) (Fig. 1, again): R = 1/TB Rate is also called channel capacity C. If the bit time is 10 ns, the data rate equals: R = 1/10 x 10–9 = 100 million bits/s This is usually expressed as 100 Mbits/s. -

To be specific, consider the statement `classical mechanics is symmetric under mirror inversion' which can be defined as follows: take any motion that satisfies the laws of classical mechanics. Then, reflect the motion into a mirror and imagine that the motion in the mirror is actually happening in front of your eyes, and check if the motion satisfies the same laws of clas- sical mechanics. If it does, then classical mechanics is said to be symmetric under mirror inversion. Or more precisely, if all motions that satisfy the laws of classical mechanics also satisfy them after being re- flected into a mirror, then classical mechanics is said to be symmetric under mirror inversion. In general, suppose one applies certain transformation to a motion that follows certain law of physics, if the resulting motion satisfies the same law, and if such is the case for all motion that satisfies the law, then the law of physics is said to be sym- metric under the given transformation. It is important to use exactly the same law of physics after the transfor- mation is applied. -

An Interpreter's Glossary at a Conference on Recent Developments in the ATLAS Project at CERN
Faculteit Letteren & Wijsbegeerte Jef Galle An interpreter’s glossary at a conference on recent developments in the ATLAS project at CERN Masterproef voorgedragen tot het behalen van de graad van Master in het Tolken 2015 Promotor Prof. Dr. Joost Buysschaert Vakgroep Vertalen Tolken Communicatie 2 ACKNOWLEDGEMENTS First of all, I would like to express my sincere gratitude towards prof. dr. Joost Buysschaert, my supervisor, for his guidance and patience throughout this entire project. Furthermore, I wanted to thank my parents for their patience and support. I would like to express my utmost appreciation towards Sander Myngheer, whose time and insights in the field of physics were indispensable for this dissertation. Last but not least, I wish to convey my gratitude towards prof. dr. Ryckbosch for his time and professional advice concerning the quality of the suggested translations into Dutch. ABSTRACT The goal of this Master’s thesis is to provide a model glossary for conference interpreters on assignments in the domain of particle physics. It was based on criteria related to quality, role, cognition and conference interpreters’ preparatory methodology. This dissertation focuses on terminology used in scientific discourse on the ATLAS experiment at the European Organisation for Nuclear Research. Using automated terminology extraction software (MultiTerm Extract) 15 terms were selected and analysed in-depth in this dissertation to draft a glossary that meets the standards of modern day conference interpreting. The terms were extracted from a corpus which consists of the 50 most recent research papers that were publicly available on the official CERN document server. The glossary contains information I considered to be of vital importance based on relevant literature: collocations in both languages, a Dutch translation, synonyms whenever they were available, English pronunciation and a definition in Dutch for the concepts that are dealt with. -

Helicity of the Neutrino Determination of the Nature of Weak Interaction
GENERAL ¨ ARTICLE Helicity of the Neutrino Determination of the Nature of Weak Interaction Amit Roy Measurement of the helicity of the neutrino was crucial in identifying the nature of weak interac- tion.

His research interests are in periment on the determination of helicity of the neutrino nuclear, atomic and falls in a similar category among experiments in the field accelerator physics. of modern physics. The experiments on the discovery of parity violation in 1957 [1] had established that the vi- olation parity was maximal in beta decay and that the polarisation of the emitted electron was 100%. This im- plies that its helicity was −1. The helicity of a particle is a measure of the angle (co- sine) between the spin direction of the particle and its momentum direction. H = σ.p,whereσ and p are unit vectors in the direction of the spin and the momentum, respectively. The spin direction of a particle of posi- tive helicity is parallel to its momentum direction, and for that of negative helicity, the directions are opposite (Box 1). -
Parity Alternating Permutations Starting with an Odd Integer
Parity alternating permutations starting with an odd integer Frether Getachew Kebede1a, Fanja Rakotondrajaob aDepartment of Mathematics, College of Natural and Computational Sciences, Addis Ababa University, P.O.Box 1176, Addis Ababa, Ethiopia; e-mail: [email protected] bD´epartement de Math´ematiques et Informatique, BP 907 Universit´ed’Antananarivo, 101 Antananarivo, Madagascar; e-mail: [email protected] Abstract A Parity Alternating Permutation of the set [n] = 1, 2,...,n is a permutation with { } even and odd entries alternatively. We deal with parity alternating permutations having an odd entry in the first position, PAPs. We study the numbers that count the PAPs with even as well as odd parity. We also study a subclass of PAPs being derangements as well, Parity Alternating Derangements (PADs). Moreover, by considering the parity of these PADs we look into their statistical property of excedance.

Title: Parity Non-Conservation in Β-Decay of Nuclei: Revisiting Experiment and Theory Fifty Years After
Title: Parity non-conservation in β-decay of nuclei: revisiting experiment and theory fifty years after. IV. Parity breaking models. Author: Mladen Georgiev (ISSP, Bulg. Acad. Sci., Sofia) Comments: some 26 pdf pages with 4 figures. In memoriam: Prof. R.G. Zaykoff Subj-class: physics This final part offers a survey of models proposed to cope with the symmetry-breaking challenge. Among them are the two-component neutrinos, the neutrino twins, the universal Fermi interaction, etc. Moreover, the broken discrete symmetries in physics are very much on the agenda and may occupy considerable time for LHC experiments aimed at revealing the symmetry-breaking mechanisms. Finally, an account of the achievements of dual-component theories in explaining parity-breaking phenomena is added. 7. Two-component neutrino In the previous parts I through III of the paper we described the theoretical background as well as the bulk experimental evidence that discrete group symmetries break up in weak interactions, such as the β−decay. This last part IV will be devoted to the theoretical models designed to cope with the parity-breaking challenge. The quality of the proposed theories and the accuracy of the experiments made to check them underline the place occupied by papers such as ours in the dissemination of symmetry-related matter of modern science. 7.1. Neutrino gauge In the general form of β-interaction (5.6) the case Ck' = ±Ck (7.1) is of particular interest. It corresponds to interchanging the neutrino wave function in the parity-conserving Hamiltonian ( Ck' = 0 ) with the function ψν' = (! ± γs )ψν (7.2) In as much as parity is not conserved with this transformation, it is natural to put the blame on the neutrino. -

The Three Myths of Optical Capacity Scaling How to Maximize and Monetize Subsea Cable Capacity

This paper will discuss scaling along each of these axes, but it is important to clarify exactly what is being scaled. There are at least three interpretations: • Increasing the data rate per wavelength • Increasing the capacity per line card or appliance • Increasing the total fiber capacity, or spectral efficiency These can potentially be scaled independently, or in concert as transponder technology evolves. In subsea deployments total fiber capacity, or spectral efficiency, is usually the dominant factor in determining overall network economics, so it becomes extremely important to understand the most effective way to achieve total capacity, especially when scaling baud rate has become a focal point for many dense wavelength-division multiplexing (DWDM) vendors today. -
