description: We show how the SUSY flavour and CP problems can be solved using gauged SU(3) family symmetry previously introduced to describe quark and lepton masses and mixings, in particular neutrino tri-bimaximal mixing via constrained sequential dominance. The Yukawa and soft trilinear and scalar mass squared matrices and kinetic terms are expanded in powers of the flavons used to spontaneously break the SU(3) family symmetry, and the canonically normalized versions of these matrices are constructed. The soft mass matrices are then expressed in the Super-CKM basis, and the leading order mass insertion parameters are calculated, and are shown to satisfy the experimental constraints from flavour changing neutral current processes. Assuming that CP is spontaneously broken by the flavons, the next-to-leading order effects responsible for CP violation are then estimated, and the predictions for electric dipole moments are shown to be an order of magnitude more suppressed than those predicted from the constrained minimal supersymmetric standard model (CMSSM), and may be further suppressed if the high energy trilinear soft parameter is assumed to be relatively small. We also predict that, unlike in the CMSSM, epsilon_K'/epsilon_K may be dominated by the SUSY operator O_8. We also discuss the additional constraints from unification, which can lead to further predictions for flavour changing in our scheme.

description: Contexte : La prise en soins de l’infirmière implique la reconnaissance des signes cliniques de maltraitance, les soins apportés à l’enfant ainsi que le signalement et la collaboration avec des autorités de protection de l’enfance. Ces différentes interventions sont influencées par plusieurs dimensions et peuvent avoir des répercussions durables sur l’enfant, l’infirmière et la famille. Objectif : Identifier les éléments pouvant favoriser ou entraver une prise en soins optimale concernant les enfants victimes de maltraitance. Méthode : Revue de littérature issue de deux bases de données : PubMed et CINAHL. Les sept articles sélectionnés ont été analysés selon la grille de Fortin. Les résultats ont été organisés sous forme de tableau suivi d’une synthèse des résultats, en lien avec la théorie du caring bureaucratique. Résultats : Les principaux obstacles à la prise en soins sont : la difficulté d’accès à des protocoles, la peur des représailles et le conflit entre le rôle d’aidant et de policier. Les facteurs facilitateurs sont la formation dans le domaine de la maltraitance infantile, l’interdisciplinarité, l’utilisation de techniques de soins adaptées à l’enfant et le contexte. L’obligation de signaler et la relation avec la famille sont des résultats ambivalents. L’utilisation du cadre théorique a permis de rassembler les variables qui influencent une prise en soins optimale de l’enfant victime de maltraitance sous différentes catégories. Conclusion : Les résultats obtenus permettent d’identifier les facteurs favorisant une prise en soins optimale ainsi que les améliorations possibles.

description: This volume covers Leg 43 of the cruises of the Drilling Vessel Glomar Challenger. Leg 43 began on 13 June 1975 at Istanbul, Turkey, and terminated 12 August 1975 in Norfolk, Virginia. We drilled six holes at six sites (382-387) on Leg 43. Leg 43 was planned to examine a wide variety of geological problems at numerous sites in the deep western North Atlantic basin. A variety of objectives were to be addressed on Leg 43, the principal emphasis being concentrated on, but not limited to, the following: 1) To core continuously through the major acoustic horizons ("A", A*, and ß) at several locations in the basin to establish the lithostratigraphic and chronostratigraphic correlations of the reflectors, and to determine if variations in these correlations could be related to lateral changes in acoustic character of the reflectors. 2) To investigate the sedimentary development of the North American basin with particular emphasis on (a) the age and nature of presumed calcareous sediments below the most seaward occurrence of Horizon ß on the western Bermuda Rise, (b) the seaward limit of Lower Cretaceous black clays in the western North Atlantic, the cause of the black-clay deposition, and the depth limits within which the clays were deposited, (c) the age, distribution and origin of the multicolored clays overlying the black clays, (d) the sources and distribution of the markedly siliceous Paleogene sediments on the Bermuda Rise, and (e) the role of surface/abyssal currents and surface productivity patterns in the Mesozoic and Cenozoic development of the sedimentary record. 3) To recover sediments containing late Mesozoic and Cenozoic fossils for biostratigraphic, paleobiogeographic, and paleoceanographic studies. 4) To recover samples of basaltic basement from the smooth crest of the basement ridge associated with the high-amplitude "J" magnetic anomaly north of the New England seamounts and determine whether the anomaly is accompanied by unusual basement composition and magnetic properties. 5) To examine the age and nature of volcanism on Bermuda and along the New England seamount chain, in order to test ideas on volcani* origin such as the "hot-spot" hypothesis, and to examine volcaniclastic lithofacies and assess the role of volcanic sources for certain North Atlantic sediments. 6) To determine the age of basement in the central part and at the young end ("J-anomaly") of the Keathley (M-series) magnetic anomalies, and in the older part of the Cretaceous "magnetic quiet zone," in order to better calibrate the M-series (Keathley) reversal chronology and the sea-floor-spreading history of the North Atlantic.
Bispectrality of multivariable Racah-Wilson polynomials

description: We construct a commutative algebra A_x of difference operators in R^p, depending on p+3 real parameters which is diagonalized by the multivariable Racah polynomials R_p(n;x) considered by Tratnik [27]. It is shown that for specific values of the variables x=(x_1,x_2,...,x_p) there is a hidden duality between n and x. Analytic continuation allows us to construct another commutative algebra A_n in the variables n=(n_1,n_2,...,n_p) which is also diagonalized by R_p(n;x). Thus R_p(n;x) solve a multivariable discrete bispectral problem in the sense of Duistermaat and Grunbaum [8]. Since a change of the variables and the parameters in the Racah polynomials gives the multivariable Wilson polynomials [26], this change of variables and parameters in A_x and A_n leads to bispectral commutative algebras for the multivariable Wilson polynomials.

Statistics, ethics, and probiotica

description: A randomized clinical trial comparing an experimental new treatment to a standard therapy for a life-threatening medical condition should be stopped early on ethical grounds, in either of the following scenarios: (1) it has become overwhelmingly clear that the new treatment is better than the standard; (2) it has become overwhelmingly clear that the trial is not going to show that the new treatment is any better than the standard. The trial is continued in the third scenario: (3) there is a reasonable chance that the new treatment will finally turn out to be better than the standard, but we aren't sure yet. However, the (blinded) data monitoring committee in the "PROPATRIA" trial of an experimental probiotica treatment for patients with acute pancreatitis allowed the trial to continue at the half way interim analysis, in effect because there was still a good chance of proving that the probiotica treatment was very harmful to their patients. The committee did not know whether treatment A was the probiotica treatment or the placebo. In itself this should not have caused a problem, since it could easily have determined the appropriate decision under both scenarios. Were the decisions in the two scenarios different, then the data would have to be de-blinded, in order to determine the appropriate decision. The committee mis-read the output of SPSS, which reports the smaller of two one-sided p-values, without informing the user what it is doing. It seems that about 5 lives were sacrificed to the chance of getting a significant result that the probiotica treatment was bad for the patients in the trial.

On the dynamics of spacecraft with a slewing appendage
Creators: name: Mah, Harry Wayne
Publisher: name: University of British Columbia
Year: 2010

description: A relatively general formulation for studying librational dynamics of a rigid satellite with a rigid appendage free to undergo any arbitrary slewing motion is developed. The governing nonlinear, nonautonomous and coupled equations are solved numerically. A parametric study suggests that the system can become unstable under critical combinations of inertia, geometric, orbital and slewing time history parameters. The fundamental information is relevant to the design of satellites and the Orbiter based experiments, and construction of the proposed space station, which would involve complex slewing motion of structural components.

description: We introduce a model which uses semi-analytic techniques to trace formation and evolution of galaxy disks in their cosmological context. For the first time we model the growth of gas and stellar disks separately. In contrast to previous work we follow in detail the angular momentum accumulation history through the gas cooling, merging and star formation processes. Our model successfully reproduces the stellar mass--radius distribution and gas-to-stellar disk size ratio distribution observed locally. We also investigate the dependence of clustering on galaxy size and find qualitative agreement with observation. There is still some discrepancy at small scale for less massive galaxies, indicating that our treatment of satellite galaxies needs to be improved.

description: While the structure of chromatin has been studied in great detail on length scales below 30 nm, amazingly little is known about the higher-order folding motifs of chromatin in interphase. Recent experiments give evidence that the folding may depend locally on gene density and transcriptional activity and show a leveling-off at long distances where approximately $ \sim O(1)$. We propose a new model that can explain this leveling-off by the formation of random loops. We derive an analytical expression for the mean square displacement between two beads where the average is taken over the thermal ensemble with a fixed but random loop configuration, while quenched averaging over the ensemble of different loop configurations -- which turns out to be equivalent to averaging over an ensemble of random matrices -- is performed numerically. A detailed investigation of this model shows that loops on all scales are necessary to fit experimental data.

description: Nonlinear optical properties, such as bulk photovoltaic effects, possess great potential in energy harvesting, photodetection, rectification, etc. To enable efficient light-current conversion, materials with strong photo-responsivity are highly desirable. In this work, we predict that monolayer Janus transition metal dichalcogenides (JTMDs) in the 1T' phase possess colossal nonlinear photoconductivity owing to their topological band mixing, strong inversion symmetry breaking, and small electronic bandgap. 1T' JTMDs have inverted bandgaps on the order of 10 meV and are exceptionally responsive to light in the terahertz (THz) range. By first-principles calculations, we reveal that 1T' JTMDs possess shift current (SC) conductivity as large as $2300 ~\rm nm \cdot μA / V^2$, equivalent to a photo-responsivity of $2800 ~\rm mA/W$. The circular current (CC) conductivity of 1T' JTMDs is as large as $10^4~ \rm nm \cdot μA / V^2$. These remarkable photo-responsivities indicate that the 1T' JTMDs can serve as efficient photodetectors in the THz range. We also find that external stimuli such as the in-plane strain and out-of-plane electric field can induce topological phase transitions in 1T' JTMDs and that the SC can abruptly flip their directions. The abrupt change of the nonlinear photocurrent can be used to characterize the topological transition and has potential applications in 2D optomechanics and nonlinear optoelectronics.

description: We carry out a detailed analysis of the scalar sector of the nonminimal supersymmetric standard model with lepton number violation, and study the constraints imposed on it by the stability of the electroweak symmetry breaking vacuum. The model contains a trilinear lepton mumber violating term in the superpotential together with the associated \susy breaking interactions which can give rise to neutrino masses. We evaluate the mass matrices for the various boson and fermion modes and then discuss the effect that the lepton number violating interactions have on the mass spectra using a phenomenological precription to implement the experimental constraints on the light neutrinos mass matrix. We also discuss qualitatively the conditions on the lepton number violating parameters set by the unbounded from below directions, and from the absence of the charge and color breaking minima in this model.

Development of a Multiparametric Lidar with the depolarization sensor
Creators: name: Nasti, Libera
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: The topic of this work was the design, the realization and the calibration of the depolarization sensor added in the Napoli Lidar (Light Detection and Ranging) system. In addition a complete rebuilding of the receiving system was operated, and a new characterization of all the components of the apparatus was done.
From the advent of Lidar technology in 1970 the study of the composition of the atmosphere gets a speed up. Lidar is an active sensor that sends into the atmosphere a short laser pulse and measures the elastic and Raman shifted optical backscattered power from molecules and aerosols. From the delay of the received pulse, the position of the scattering elements is obtained. Analyzing the backscattered radiation some important optical properties of the atmospheric aerosols can be derived: backscattering and extinction coefficients, position and altitude of the layers, colour index and so on.
In this context, a depolarization-sensitive Lidar can help to characterize the particle’s shape.
The discrimination of the shape of the aerosols is very important, for example to distinguish the phase of the clouds (ice-clouds are strongly asymmetric scatterers while low clouds are made by spherical water’s drops) and the type of aerosols (Saharan dust is constituted by non-spherical particles while urban aerosols by little spherical particles).
The depolarization measurements can be performed by using a linearly polarized laser source and a hardware configuration of the receiving system including two channels detecting simultaneously the backscattered radiation in the parallel and orthogonal direction with respect to the laser beam.
The total depolarization ratio, due both to molecular and aerosol contributions, is simply the calibrated ratio of the orthogonal signal to the parallel one. So, a key question to obtain high quality depolarization measurements is performing a good calibration of the Lidar system.
In this work different calibration techniques were analyzed by simulating lidar signals in different atmospheric conditions. In Napoli the sensor was realized and then calibrated while in Potenza the depolarization sensor was only calibrated. These two systems were calibrated with different techniques, due to different apparatus conditions.
My scientific activity was spent for the most in the Atomic and Laser Applications Laboratory in Physics Department of University Federico II of Napoli.
A period of three months was also spent in C.N.R.-I.S.A.C.(Istituto di Scienze Atmosferiche e Climatiche), in Bologna, where some theoretical models about the atmospheric dynamic were developed. Two months period was also spent in C.N.R.-I.M.A.A. (Istituto di Metodologie per l’Analisi Ambientale- Tito Scalo-Potenza), working under the supervision of Dr. Gelsomina Pappalardo.

description: By phenomenological Landau analysis, it is shown that a scalar order parameter with the point-group symmetry $Γ_{1g}$ explains most properties associated with the phase transition in PrFe$_4$P$_{12}$ at 6.5 K. The scalar-order model reproduces magnetic and elastic properties in PrFe$_4$P$_{12}$ consistently such as (i) the anomaly of the magnetic susceptibility and elastic constant at the transition temperature, (ii) anisotropy of the magnetic susceptibility in the presence of uniaxial pressure, and (iii) the anomaly in the elastic constant in magnetic field. An Ehrenfest relation is derived which relates the anomaly of the magnetic susceptibility to that of the elastic constant at the transition.

description: Cosmic ray (CR) hydrodynamics is a (re-)emerging field of high interest due to the importance of CRs for the dynamical evolution of the interstellar, the circumgalactic, and the intracluster medium. In these environments, CRs with GeV energies can influence large-scale dynamics by regulating star formation, driving galactic winds or by altering the pressure balance of galactic halos. Recent efforts have moved the focus of the community from a one-moment description of CR transport towards a two-moment model as this allows for a more accurate description of the microphysics impacting the CR population. Like all hydrodynamical theories, these two-moment methods require a closure relation for a consistent and closed set of evolution equations. The goal of this paper is to quantify the impact of different closure relations on the resulting solutions. To this end, we review the common P1 and M1 closure relations, derive a new four-moment H1 description for CR transport and describe how to incorporate CR scattering by Alfvén waves into these three hydrodynamical models. While there are significant differences in the transport properties of radiation in the P1 and M1 approximations in comparison to more accurate radiative transfer simulations using the discrete ordinates approximation, we only find small differences between the three hydrodynamical CR transport models in the free streaming limit when we neglect CR scattering. Most importantly, for realistic applications in the interstellar, circumgalactic or intracluster medium where CR scattering is frequent, these differences vanish and all presented hydrodynamical models produce the same results.

Danni di guerra e restauro dei monumenti. Palermo 1943-1955
Creators: name: Scaturro, Giuseppe

Year: 2006

description: Muovendo dall’analisi del titolo “Danni di guerra e restauro dei monumenti. Palermo 1943-1955” si possono riscontrare i contenuti ed i concetti elaborati nello scritto, poiché ogni sua parte individua una distinta tematica di studio.
Quale argomento? “Danni di guerra e restauro dei monumenti”: un tema riguardante la conoscenza delle distruzioni subite dal patrimonio monumentale in occasione di un evento bellico (nella fattispecie la seconda guerra mondiale) e lo studio del conseguente restauro di tali manufatti alla luce dei danni riportati.
Dove? A Palermo, dunque in un preciso e definito luogo geografico individuato in Sicilia e rappresentato dalla sua città capoluogo.
Quando?  Nel periodo compreso tra l’anno 1943 ed il 1955, esattamente coincidente con il servizio amministrativo svolto nel ruolo di Soprintendente ai Monumenti della Sicilia Occidentale prima dall’architetto Mario Guiotto e poi dal suo collega a lui succeduto Armando Dillon.
Il lavoro si articola sulle seguenti tematiche di studio, fondate sulla conoscenza e sulla successiva fase di comprensione critica degli eventi bellici e della conseguente attività di tutela intrapresa attraverso i restauri condotti sul patrimonio monumentale offeso, le quali hanno caratterizzato le diverse fasi del lavoro svolto:
1)	“Il servizio della tutela dei monumenti in Sicilia prima degli eventi bellici: organizzazione, protagonisti ed interpreti; 2) “Gli eventi bellici del 1943 a Palermo e i danni al patrimonio monumentale; 3) “1943-1955: l’opera di ricostruzione post-bellica a Palermo; 4) “Il restauro dei monumenti danneggiati dalla guerra: i casi esemplari e le tematiche di intervento.
In ultima analisi, la comprensione critica delle caratteristiche e delle modalità degli interventi operati dai due protagonisti porta a dedurre che in Sicilia non si è in presenza di una realtà chiusa in sè e avulsa dagli sviluppi del dibattito culturale che si andava svolgendo in Italia ed in Europa, ma di una prassi operativa che, per i contenuti tematici, può confrontarsi a pieno titolo, sul terreno delle esperienze d’intervento condotte su eccezionali preesistenze, con le altre realtà regionali della Penisola.
Rabies in Cats: Implications, Diagnosis, and Future Directions

description: Rabies is a highly fatal viral disease affecting the central nervous system of mammals, including humans, with global public health significance. Although rabies is most commonly associated with domestic dogs, cats are increasingly recognized as important vectors for the transmission of the rabies virus, particularly in areas where vaccination coverage is inconsistent or limited. As a zoonotic disease, rabies poses a critical risk not only to animals but also to human populations, with domestic cats sometimes acting as intermediaries between wild rabies reservoirs and humans. Despite being less prominently associated with rabies outbreaks compared to dogs, the role of cats in the epidemiology of rabies is significant, especially given the close proximity between domestic cats and human households.

description: Aims: I have analyzed a sample of seven nearby edge-on galaxies observed in the V and K'-band, in order to infer the properties of the dust distribution. Methods: A radiative transfer model, including scattering, have been used to decompose each image into a stellar disk, a bulge, and a dust disk. The parameters describing the distributions have been obtained through standard X^2 minimization techniques. Results: The dust disks fitted to the V-band images are consistent with previous work in literature: the radial scalelength of dust is larger than that for stars (h_d/h_s ~ 1.5); the dust disk has a smaller vertical scalelength than the stellar (z_d/z_s ~ 1/3); the dust disk is almost transparent when seen face-on (central, face-on, optical depth tau_0 =0.5-1.5). Faster radiative transfer models which neglect scattering can produce equivalent fits, with changes in the derived parameters within the accuracy of full fits including scattering. In the K'-band, no trace is found of a second, massive, dust disk which has been invoked to explain observations of dust emission in the submillimeter. I discuss the model degeneracies and the effect of complex structures on the fitted distributions. In particular, most bulges in the sample show a box/peanuts morphology with large residuals; two lower-inclination galaxies show a dust ring distribution, which could be the cause for the large fitted dust scalelengths.

description: The computational analysis of high dimensional surfaces is a fundamental problem across a wide range of scientific fields, for example in the study of models of clusters of atoms, glasses, self-assembling systems, and biomolecules; machine learning; physics; and other fields. This work presents a variety of novel methods developed to aid the computational study of the structures, dynamics, and thermodynamics of systems described by these surfaces, traditionally termed energy landscapes. When studying molecular systems, it is important to be able to quantify measures of similarity or difference between a pair of structures generated from an energy landscape. These measures are needed to make predictions of the properties of a given molecular structure from the known properties of similar others. Equivalently a pair of structures can be aligned into similar orientations to allow an interpolated pathway to be generated between them which can be used to identify the transition states between the pair which is a key limiting step in discrete path sampling. The efficiency of the transition state search is strongly dependent on the quality of the initial interpolation and so the alignment methods used. In this work two novel alignment algorithms are presented and benchmarked against existing algorithms for aligning pairs of structures for both periodic and isolated clusters of atoms. The algorithms respectively demonstrate superior performance for either periodic or isolated structures. The efficient evaluation of the global thermodynamic properties of an in silico system, or analogously, the evidence in Bayesian inference, is a challenge for many high-dimensional systems due to a phenomenon known as broken ergodicity. This problem occurs when the energy barriers between different regions of the energy landscape make it difficult to sample both uniformly. In this work a novel superposition based approach that is embarrassingly parallel, based on the athermal method nested sampling, is introduced and benchmarked against a model system exhibiting broken ergodicity. It is shown that the method reproduces the key features of the heat capacity

Estimation of error rates and fade distributions on a Rayleigh fading channel with additive white Gaussian noise

Publisher: name: University of British Columbia
Year: 2010

description: Several characteristics of the Rayleigh fading channel are examined. A digital Rayleigh fading simulator is used to generate the (fading) signal envelope from which various statistics are derived. Based on the simulation results, a simple model is proposed in order to estimate the block error rate of a block of N data bits transmitted over the Rayleigh fading channel in the presence of additive white Gaussian noise. This model gives an average estimation error of about 4 % over the range of blocksizes N = 63, 127, 255, 511, 1023, 2047 (bits), average signal-to-noise ratios 70 = 5 to 35 (dB) and fading frequencies f[sub D] = 10 to 90 (Hz) corresponding to vehicle speeds of 8 to 71 MPH at a radio carrier frequency of 850 MHz. A second somewhat more complex model for estimating the block error rate is found to yield a lower average estimation error of 2.4 % over the same set of simulated data. The probability distributions of the fade rate and the fade duration are also examined. Empirical models are derived for the estimation of the probability mass function of the fade rate and the probability density function of the fade duration. These empirical models allow fairly accurate estimates without the need for cosdy and time-consuming simulations. The probability of m-bit errors in an N-bit block is an important parameter in the design of error-correcting codes for use on the mobile radio channel. However, such probabilities are difficult to determine without performing extensive simulation or field trials. An approach to estimate them empirically is proposed.
Proto-magnetar jets as central engines for broad-lined type Ic supernovae

description: A subset of type Ic supernovae (SNe Ic), broad-lined SNe Ic (SNe Ic-bl), show unusually high kinetic energies ($\sim 10^{52}$ erg) which cannot be explained by the energy supplied by neutrinos alone. Many SNe Ic-bl have been observed in coincidence with long gamma-ray bursts (GRBs) which suggests a connection between SNe and GRBs. A small fraction of core-collapse supernovae (CCSNe) form a rapidly-rotating and strongly-magnetized protoneutron star (PNS), a proto-magnetar. Jets from such magnetars can provide the high kinetic energies observed in SNe Ic-bl and also provide the connection to GRBs. In this work we use the jetted outflow produced in a 3D CCSN simulation from a consistently formed proto-magnetar as the central engine for full-star explosion simulations. We extract a range of central engine parameters and find that the extracted engine energy is in the range of $6.231 \times 10^{51}-1.725 \times 10^{52}$ erg, the engine time-scale in the range of $0.479-1.159$ s and the engine half-opening angle in the range of $\sim 9-19^{\circ}$. Using these as central engines, we perform 2D special-relativistic (SR) hydrodynamic (HD) and radiation transfer simulations to calculate the corresponding light curves and spectra. We find that these central engine parameters successfully produce SNe Ic-bl which demonstrates that jets from proto-magnetars can be viable engines for SNe Ic-bl. We also find that only the central engines with smaller opening angles ($\sim 10^{\circ}$) form a GRB implying that GRB formation is likely associated with narrower jet outflows and Ic-bl's without GRBs may be associated with wider outflows.

Secondary range compression for improved range/Doppler processing of SAR data with high squint
Creators: name: Schmidt, Alfred Rudolf
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines a new algorithm, to be called secondary range compression (SRC), for significantly improving the range resolution of the range/Doppler synthetic aperture radar (SAR) processing algorithm when the radar antenna is significantly squinted away from the zero Doppler direction. The algorithm was recently introduced by Jin and Wu [13] for application to the SEASAT SAR sensor. Significant extensions of their algorithm and models are presented. First the model of range broadening in the basic range/Doppler algorithm is extended by using a more general form for the range compressed profile. A mathematical theory is developed to examine more closely the approximations involved in both basic range/Doppler processing and SRC and to explore alternate SRC implementations. The theory is used to derive the SRC algorithm as a matched filter directly from the point target response model rather from the simplified range compressed response used by Jin and Wu. Two new discrete implementations (azimuth SRC and range SRC) are developed for both single-look and multilook processing. In addition two new alternate methods of multilook SRC are presented : fixed SRC and look-dependent SRC. The sensitivity of the SRC algorithms to parameter errors is investigated. Extensive simulations are developed to quantify the image quality produced by each algorithm for a variety of processing parameters. The simulation results with nominal RADARSAT parameters show that the SRC algorithms can significantly extend the range of squint angles which can be processed with the range/Doppler type of algorithm.

description: 2 August 2014, MediaCityUK: A one-off performance of visual, dance, music and sound artists, plus a super-choir of hundreds. It explored the human impact of World War One.

Using texts from Welsh language War Poet, Hedd Wyn and archive materials from the Imperial War Museum North, audiences were given a window into the lives of those who fought on the front lines of the war and at home. Artists included Creative Director, Craig Morrison; German duo Hartung Trenz and Wales-based animator Sean Vicary, who were invited to use projected text and carefully curated imagery; Sharon Watson of Phoenix Dance Theatre, bringing physical performance to assist the storytelling; Theatre In The Quarter relaying the experiences of the region’s dockworkers enlisted to serve in battle through audio drama; and an emotionally charged ‘Super Choir’ performing a specially written piece by acclaimed composer Andy Smith and conducted by renowned Choral Director, Jeff Borradaile.

The playscript sections were created by Helen Newall, directed by Matt Baker, and constituted a storyboard for the narrative animations created by the animators. Performers were lit and micced, and visible to the audience, but the impact was of a radio or audio play within the projected visuals of the piece as a whole. Playscript performers were professional actors: Ben Tolley; Joanna Higson; Danny Childs Commissioned by Quays Culture. Funded by Arts Council England and AGMA. Supported by The Quays and MediaCityUK.

L’architettura romanica nel territorio dauno lungo la via peregrinorum
Creators: name: Di Tizio, Antonio
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: L'esaltazione di un linguaggio architettonico sviluppatosi nell'arco di secoli, molto legato al territorio e da esso plasmato, è dovuto anche alla conoscenza di opere “minori” quali la chiesa di Santa Maria Maggiore di Siponto e San Leonardo di Siponto, opere emblematiche del romanico pugliese e della sua interpretazione da parte del popolo dauno. Tutte le scelte operative effettuate sono derivate da attente valutazioni sulla morfologia del monumento e si sono fondate sul principio secondo il quale il rilievo del patrimonio architettonico ed ambientale è considerato non solo la base preliminare ad ogni intervento di tutela e di trasformazione di qualsiasi opera di architettura, ma anche una esperienza altamente formativa per chiunque operi nell'ambito della conoscenza e tutela dei beni culturali.
I casi analizzati sono esemplificativi di un linguaggio, diffuso in tutta Europa ed in Puglia in particolare, che sia in San Leonardo che in Santa Maria trova una interpretazione fortemente caratterizzata dalla cultura e dalle conoscenze tecniche del popolo dauno.
