Helium

View this topic in
Helium is the chemical element with atomic number 2 and an atomic weight of 4.002602, which is represented by the symbol He. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions. (Wikipedia.org)

Sizing exit buffers in ATM networks: an intriguing coexistence of instability and tiny cell loss rates

[{u'author_order': 1, u'affiliation': u'Dept. of Comput. Sci., Tel Aviv Univ., Israel', u'full_name': u'H. Levy'}, {u'author_order': 2, u'full_name': u'T. Mendelson'}, {u'author_order': 3, u'full_name': u'M. Sidi'}, {u'author_order': 4, u'full_name': u'J. Keren-Zvi'}] IEEE/ACM Transactions on Networking, 1999

This paper deals with the sizing of end buffers in ATM networks for sessions subject to constant bit rate (CBR) traffic. Our objective is to predict the cell-loss rate at the end buffer as a function of the system parameters. We introduce the D+G/D/1 queue as a generic model to represent exit buffers in telecommunications networks under constant rate traffic, ...

We performed particle composition analysis of clean room particles by using a particle analyzer (PT1000) and a Cyclone Particle Sampler. While we expected to find only small particles in the clean room, we detected many large particles as well. Many floating particles are greatly influenced by air flow current. Particles are created by human movement and we speculate that this ...


Maximized L-Measure and Its Choquet Integral Regression Model

The well known normalized monotone measures, ¿-measure and P-measure, have only one formulaic solution. A multivalent normalized monotone measure with infinitely many solutions was proposed by our previous work, called L-measure, but L-measure is not a completed measure. And then, a completed measure with more many solutions than L-measure, called completed L-measure, was proposed by our next previous work, In ...

Having reliable context sources is very important for context-aware applications and the devices around a user can be a useful context for many applications. While the importance of `devices around' as a context has been highlighted many times, to the best of our knowledge, there is no systematic mechanism reported to identify and capture this context. In this paper we ...

  • Cryogenics

    This chapter discusses ways of cooling detectors, some associated calculations, measuring the temperatures, and the safety hazards. Work at low temperatures require calculations of the time required for components to cool, the ultimate temperature they will reach, and the amount of cryogen used in the cooling process. The chapter also discusses the thermal properties and how the required calculations are done. Conduction from room temperature into the cryogen is minimized by using supports with the smallest possible cross section and as long as possible. The measurement of temperatures is an important part of cryogenics. Several potential safety hazards exist when working with cryogens, but simple precautions are available to protect against all of them. If miniature gas lines (used to supply gaseous nitrogen to open‐cycle refrigerators) should break while under pressure, they can whip around, causing serious cuts or eye damage.

  • Terrestrial Radiation Fields

    Chapter 2 summarises terrestrial radiation sources including radiation originated from cosmic rays and radiation from radioisotopes that have natural abundance. Radioisotopes released from the Fukushima Daiichi nuclear power plants by severe accident are included. Their energy spectra are also summarised.
