Thin Film Thermal Deposition at Various Pressures

This research was to verify the hypothesis that resistivity of metal\u27s thin film deposited in a low-pressure environment is the same as its solid material. Thermal Evaporation is a thin film deposition technique in which metal inside a vacuum is evaporated, then deposited onto a surface. Higher quality metal films are deposited when the vacuum pressure is lower. At higher pressures, more air molecules are trapped within the layers of metal, thus increasing scattering sites and increasing the resistance. However, reaching a lower pressure requires more time and effort. In this research, films were deposited at various pressures and resistivities were calculated for each film to determine an ideal pressure range that creates the least resistivity

Seeing the light – finding the poetic content of design objects

This paper presents the process and initial results of a research through design project attempting to understand the poetic qualities of design objects. This exploration forms part of a PhD study addressing design artefacts as poetic objects - objects that both embed and conjure memory, association and imagination. The research examines the ways in which design objects can be poetic and how designers actively and knowingly use objects to poetic effect. It is proposed that the poetic content of design artefacts can be located on a continuum ranging from the experiential - relating to how we perceive things - to the reflective and cultural. What unites these levels is the capacity of design objects to reveal and change our way of looking at things. The practice uses the design of lighting as a vehicle for exploring the poetic meaning of designed objects more generally. Starting with the notion that lights do more than provide light, the current phase of practice examines the ways in which luminaires can mediate how we perceive and experience light and explores, in particular, the more nuanced and ephemeral qualities of light that escape conscious attention

Axial Vector Z′Z' and Anomaly Cancellation

Whilst the prospect of new $Z'$ gauge bosons with only axial couplings to the Standard Model (SM) fermions is widely discussed, examples of anomaly-free renormalisable models are lacking in the literature. We look to remedy this by constructing several motivated examples. Specifically, we consider axial vectors which couple universally to all SM fermions, as well as those which are generation-specific, leptophilic, and leptophobic. Anomaly cancellation typically requires the presence of new coloured and charged chiral fermions, and we argue that in a large class of models masses of these new states are expected to be comparable to that of the axial vector. Finally, an axial vector mediator could provide a portal between SM and hidden sector states, and we also consider the possibility that the axial vector couples to dark matter. If the dark matter relic density is set due to freeze-out via the axial vector, this strongly constrains the parameter space.Comment: 28 pages, 8 figures. v2. published versio

An approximate solution technique for the constrained search path moving target search problem

A search is conducted for a target moving in discrete time among a finite number of cells according to a known Markov process. The searcher must choose one cell in which to search in each time period. The set of cells from which he can choose is a function of the cell chosen in the previous time period. The problem is to find a searcher path, i.e., a sequence of search cells, that minimizes the probability of not detecting the target in a fixed number of time periods. The problem is formulated as a nonlinear program and solved for a local optimum by a simple implementation of the convex simplex methodNaval Postgraduate School, Monterey, CA.http://archive.org/details/approximatesolut15eaglNaval Postgraduate School, Monterey, CA.NAApproved for public release; distribution is unlimited

TTA school-based research consortium initiative, the evaluation, final report

This is the final report of the evaluation of th School-Based Research Consortium Initiative which ran in England from 1998 to 2001. The initiative was sponsored via a public/private partnership between the Teacher Training Agency (TTA), a UK Government agency, and the Centre for British Teachers (CfBT), a private not-for-profit company. The aim of the initiative was to create local infrastructures of support and action for teachers to engage ‘in and with’ research. Those infrastructures were made up of consortia, consisting in each case of a small number of schools together with a university department of education and at least one local education authority (LEA). Over the three years that it ran, the initiative spawned a considerable range and volume of research activities, including peer observation of teaching, peer review of videos of teaching, interview-based study, surveys measuring such things as rewards and sanctions in the classroom. In addition to well-developed teacher-university collaborations and some joint work with local education authorities, there were many examples of teacher-teacher collaboration (some of it between different schools), and also times when teachers and pupils worked together to devise, carry out or interpret research activity. In practice, the initiative created an environment in which it was possible to develop new research relationships across a range of partners, rather than merely transfer the locus of research to schools. Three aspects of teacher experience of the initiative are important to highlight. The first was the overwhelming testimony of teachers that the value of the initiative for them was the rediscovery of their professional confidence in a climate of low trust accountability, characterised by constant monitoring, target setting and bureaucratic demands. The second was the growth of familiarity with research practices that teachers gained through working collaboratively with their peers, with pupils, and with colleagues from the university. The third was how the process of research itself was necessarily situated in teachers’ own practices

Looking for a light Higgs boson in the overlooked channel

The final state obtained when a Higgs boson decays to a photon and a Z boson has been mostly overlooked in current searches for a light Higgs boson. However, when the Z boson decays leptonically, all final state particles in this channel can be measured, allowing for accurate reconstructions of the Higgs mass and angular correlations. We determine the sensitivity of the Large Hadron Collider (LHC) running at center of masses energies of 8 and 14 TeV to Standard Model (SM) Higgs bosons with masses in the 120 - 130 GeV range. For the 8 TeV LHC, sensitivity to several times the the SM cross section times branching ratio may be obtained with 20 inverse femtobarns of integrated luminosity, while for the 14 TeV LHC, the SM rate is probed with about 100 inverse femtobarns of integrated luminosity.Comment: 4 pages, 4 figures. Improves on version 1 in that 8 and 14 TeV LHC running is considered, the case of a 125 GeV Higgs is treated specifically, and the effect of an additional jet in the final state has been taken into account in studying experimental sensitivit

Editorial: Clinical practice can save evidence-based medicine from itself

Although imperfect, the structure of this journal and its publications are demonstrations of clinicians attempting to actualize the wisdom of these foundational thinkers. We need to leave examples and guideposts to the next generation of clinicians of how to fulfill this vision of being excellent clinicians, through both formal education and role modeling
