An Application for Research: the Large Hadron Collider

The Large Hadron Collider (LHC) machine at CERN was designed and built primarily to find or exclude the existence of the Higgs boson, for which a large amount of data is needed by the LHC experiments. This requires operation at high luminosity, which in turn requires running with thousands of high-intensity proton bunches in the machine. After quantifying the data required by the experiments and elucidating the LHC parameters needed to achieve this, this paper explains how the LHC beams are fabricated from the pulse(s) coming from the CERN Duoplasmatron source.Comment: 10 pages, contribution to the CAS-CERN Accelerator School: Ion Sources, Senec, Slovakia, 29 May - 8 June 2012, edited by R.

Measuring the Lifetime of Trapped Sleptons Using the General Purpose LHC Detectors

In supergravity where the gravitino is the lightest supersymmetric particle (LSP), the next-to-lightest supersymmetric particle (NLSP) decays to the gravitino with a naturally long lifetime (10^4 - 10^8). However, cosmological constraints favour charged sleptons with lifetimes below a year as the natural NLSP candidate. For this scenario we report a method to accurately determine the slepton lifetime and SUSY cross-section from observation of the decays of sleptons trapped in the material comprising the main detector (ATLAS, CMS). A measurement of the lifetime to 5% is possible after 3 years at nominal luminosity and running conditions. This method is sensitive to the cosmologically preferred stau lifetime of ~37 days and does not require the use of ancillary trapping volumes

Electromagnetic wave energy converter

Electromagnetic wave energy is converted into electric power with an array of mutually insulated electromagnetic wave absorber elements each responsive to an electric field component of the wave as it impinges thereon. Each element includes a portion tapered in the direction of wave propagation to provide a relatively wideband response spectrum. Each element includes an output for deriving a voltage replica of the electric field variations intercepted by it. Adjacent elements are positioned relative to each other so that an electric field subsists between adjacent elements in response to the impinging wave. The electric field results in a voltage difference between adjacent elements that is fed to a rectifier to derive dc output power

Sentential Word Order and the Syntax of Question Particles

Polar question particles in languages with VO word order pose a problem for the otherwise robust Final-Over-Final Constraint, which rules out a head-final phrase immediately dominating a head-initial phrase (Holmberg 2000). This paper offers a description of these particles and the constraint, and offers data supporting the hypothesis that these final particles are different from their initial counterparts in a fundamental way

Implementation of Response to Intervention for English Language Learners

Response to Intervention is utilized to provide parents, teachers, and specialists with the data needed to implement and measure the effectiveness of evidence-based instructional and behavioral strategies matched to student needs. English Language Learners are in particular need of research-based instruction paired with progress monitoring as they seek to meet state standards in a new language. Parents, students, and school personnel all benefit from seeing Christ-like consideration for foreigners modeled through Response to Intervention

Null Subjects in Northeast English

This paper presents data and analysis relating to null subjects in spoken colloquial English. While English is not a „pro-drop? language (i.e. subjects must usually be overt), a corpus of speech collected on Tyneside and Wearside in 2007 shows that null subjects are permitted in finite clauses in certain contexts. This paper analyses these examples and follow-up questionnaires, and compares the data with the other types of null subject described in the literature (pro-drop, topic-drop, early null subjects, aphasics? null subjects and „diary-drop?), ultimately concluding that the colloquial English phenomenon is most closely related to diary- drop

Status and projections of the NAS program

NASA's Numerical Aerodynamic Simulation (NAS) Program has completed development of the initial operating configuration of the NAS Processing System Network (NPSN). This is the first milestone in the continuing and pathfinding effort to provide state-of-the-art supercomputing for aeronautics research and development. The NPSN, available to a nation-wide community of remote users, provides a uniform UNIX environment over a network of host computers ranging from the Cray-2 supercomputer to advanced scientific workstations. This system, coupled with a vendor-independent base of common user interface and network software, presents a new paradigm for supercomputing environments. Background leading to the NAS program, its programmatic goals and strategies, technical goals and objectives, and the development activities leading to the current NPSN configuration are presented. Program status, near-term plans, and plans for the next major milestone, the extended operating configuration, are also discussed

Interaction of hydrogen chloride with alumina

The influence of outgas conditions and temperature on the adsorptive properties of two aluminas Alon-c and Al6sG were studied using adsorption isotherm measurements. Alon-C and Al6SG were characterized using X-ray powder diffraction, thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and BET nitrogen surface areas. Some of these techniques were applied to two other aluminas but no isotherm data was obtained. Isotherm data and techniques applied to each alumina are summarized in tabular form

Technological ambiguity and the uneasy conscience: bringing Reinhold Niebuhr’s theology into dialogue with the philosophy of Lewis Mumford and Herbert Marcuse towards a Christian conception of responsibility in the technical age

Contemporary discussions regarding ethics in the technological society are obscured by faulty presuppositions regarding the answer to one question: is technology neutral or non-neutral? The question itself presents a binary that betrays a dimension of human nature that allows for the possibility of responsibility within the technological society to exist. We may presume human transcendence over, or contingence to, technology. In so doing, we either assuage one’s conscience of any moral deliberation whatsoever, or inhibit one’s freedom to the point of a mindless determinism. In either occasion, one is left with an easy conscience—an inability to attribute evil in the technological society to human conduct. There are at least two thinkers, Lewis Mumford and Herbert Marcuse, who frame their understanding of the question of technological neutrality in a way that diminishes the pitfalls of either position. While Mumford holds that technology is neutral, he is still attentively critical of the philosophical presumptions that led to the rise of the technological society. While Marcuse holds that technology is non-neutral, his critique of the technological society does not default to a despairing determinism. However, despite their contributions, both still presume anthropologies that lead them toward the same binary that both originally resisted, articulating the human as so transcendent over (Mumford) or contingent to (Marcuse) technology that one lacks the tensions necessary to establish an uneasy conscience—the recognition that humans are responsible for evil in the world. In response, this thesis will utilize Reinhold Niebuhr’s method of Christian Realism as a way of establishing an anthropology upon which responsibility can be maintained, but also as a way of housing both Mumford and Marcuse’s critiques of the technological society within an alternative approach that transcends the neutrality/non-neutrality binary: namely, technological ambiguity
