    The purpose of this research was to analyze three different narrative web series that were adapted into traditional television formats within the past ten years. Delving into how the creators marketed themselves, created the content, and distributed the content allows the reader to notice strategies that worked in the past to sell stories to production companies

    Measurement of the Prompt Double J/psi Production Cross Section in pp Collisions at sqrt(s) = 7 TeV

    The simultaneous production of two J/psi mesons has been significantly observed in proton-proton collisions at a center-of-mass energy of 7 TeV with the CMS detector. The two J/psi mesons are fully reconstructed in their decay to muons. The signal yield is extracted with an extended maximum likelihood fit based on four event variables. A method was developed to correct for detector acceptances and efficiencies based on the measured momenta of the J/psi and their decay muons to maintain the least model dependence possible. The measurement is performed in an acceptance region defined by the individual J/psi transverse momentum and rapidity. From the measured signal yield of 446 events corresponding to an integrated luminosity of 4:7 inverse femtobarn. The total cross section is found to be 1:49 nanobarn, with 0:07 statistical and 0:13 nb systematic error, and unpolarizaed production was assumed. Most predictions for particle production at the LHC assume dominance of single parton interaction for proton-proton collisions, which can be tested with the final state measured in this analysis. The differential cross section is measured in bins of the double J/psi invariant mass, the double J/psi transverse momentum, and the absolute difference in rapidity of the two J/psi. The reconstruction of the four charged muon trajectories heavily relies on the Pixel subdetector located close to the beampipe. Systematic studies with cosmic muons and tracks from collision events are presented. The development of the Pixel RawToDigi package, data quality monitoring packages, commissioning studies of Pixel data and tracks in first collisions, and realistic simulations of decay signals in the pixel subdetector were all performed as a part of this dissertation work

    Design implications of the new harmonised probabilistic damage stability regulations

    Get PDF
    In anticipation of the forthcoming new harmonised regulations for damage stability, SOLAS Chapter II-1, proposed in IMO MSC 80 and due for enforcement in 2009, a number of ship owners and consequentially yards and classification societies are venturing to exploit the new degrees of freedom afforded by the probabilistic concept of ship subdivision. In this process, designers are finding it rather difficult to move away from the prescription mindset that has been deeply ingrained in their way of conceptualising, creating and completing a ship design. Total freedom it appears is hard to cope with and a helping hand is needed to guide them in crossing the line from prescriptive to goal-setting design. This will be facilitated considerably with improved understanding of what this concept entails and of its limitations and range of applicability. This paper represents an attempt in this direction, based on the results of a research study, financed by the Maritime and Coastguard Agency in the UK, to assess the design implications of the new harmonised rules on passenger and cargo ships

    Fortnight is a two-week long, fully immersive, experience based in the interactions and communications of daily life. Up to 200 participants sign up to receive messages that are sent to their mobile phones, email, and home address; these messages contain a series of poetic nudges that encourage those participating to question their sense of place. Participants also receive daily invitations to visit locations throughout their city where they can pause to reflect on what it means to be here now. Fortnight enables the experience of “theatre” to penetrate beneath a seemingly brittle aesthetic surface of performance, deep into the consciousnesses of our participants as they begin to interact with and perceive world around us as the performance itself; the place where we act out our own daily lives. In Fortnight, the spectator becomes participant; the journey becomes narrative. Fortnight therefore subverts the notion of an audience, in which each spectator’s perspective is forced to examine not the situation and setting of performers on a stage, but rather the situation and setting of our own sense of place and the meaning we apportion to our everyday lives. Fortnight uses various forms of ubiquitous technology such as: Radio Frequency Identification (aka, RFID tags of the type contained in key fobs), which are used in badges sent to each participant that allow them to interact with real-world “portals” to trigger certain effects in their surroundings; QR technology (in the form of barcodes on posters that reveal additional hidden messages, should the participant choose to delve further; SMS messages; email; and, Twitter. Alongside this, older modes of communication such as handwritten letters, give Fortnight a decidedly low-fi aesthetic. Throughout Fortnight, participants are encouraged to explore the creative possibilities of pervasive and communicative media without reverting to mere technological fetishism. In Fortnight, each mode of communication is used not only for its functionality but also as symbols that bind the project and the participant together, rooting them to the here and now with the everyday tools of modern society. The mediated messages within Fortnight lead participants down a living, breathing rabbit hole where the familiar becomes unfamiliar and reality distorts. The project becomes an experience for the participant that is as immersive as their own life; creating an alternative reality, that not only co-exists alongside their own everyday realities, but also merges with them.This is a performance with shared responsibilities, reflecting the actions and consequences of our daily lives: what we put in, we get out

    Surface wave dispersion inversion using an energy likelihood function

    Get PDF
    Seismic surface wave dispersion inversion is used widely to study the subsurface structure of the Earth. The dispersion property is usually measured by using frequency-phase velocity (f-c) analysis and by picking phase velocities from the obtained f-c spectrum. However, because of potential contamination the f-c spectrum often has multimodalities at each frequency for each mode. These introduce uncertainty and errors in the picked phase velocities, and consequently the obtained shear velocity structure is biased. To overcome this issue, in this study we introduce a new method which directly uses the spectrum as data. We achieve this by solving the inverse problem in a Bayesian framework and define a new likelihood function, the energy likelihood function, which uses the spectrum energy to define data fit. We apply the new method to a land dataset recorded by a dense receiver array, and compare the results to those obtained using the traditional method. The results show that the new method produces more accurate results since they better match independent data from refraction tomography. This real-data application also shows that it can be applied efficiently since it removes the need to pick phase velocities, and with relatively little adjustment to current practice since it uses standard f-c panels to define the likelihood. We therefore recommend using the energy likelihood function rather than explicitly picking phase velocities in surface wave dispersion inversion

    Low-Energy Dynamics of String Solitons

    Full text link
    The dynamics of a class of fivebrane string solitons is considered in the moduli space approximation. The metric on moduli space is found to be flat. This implies that at low energies the solitons do not interact, and their scattering is trivial. The range of validity of the approximation is also briefly discussed.Comment: 8 pages, Minor typos correcte

    Self-Renormalization of the Classical Quasilocal Energy

    Get PDF
    Pointlike objects cause many of the divergences that afflict physical theories. For instance, the gravitational binding energy of a point particle in Newtonian mechanics is infinite. In general relativity, the analog of a point particle is a black hole and the notion of binding energy must be replaced by quasilocal energy. The quasilocal energy (QLE) derived by York, and elaborated by Brown and York, is finite outside the horizon but it was not considered how to evaluate it inside the horizon. We present a prescription for finding the QLE inside a horizon, and show that it is finite at the singularity for a variety of types of black hole. The energy is typically concentrated just inside the horizon, not at the central singularity.Comment: 7 pages, 4 figure
