3D scanning by multiple fan beam X-ray sources and sensors

*** Purpose – Computer tomography (CT) for 3D reconstruction entails a huge number of coplanar fan-beam projections for each of a large number of 2D slice images, and excessive radiation intensities and dosages. For some applications its rate of throughput is also inadequate. A technique for overcoming these limitations is outlined. *** Design methodology/approach – A novel method to reconstruct 3D surface models of objects is presented, using, typically, ten, 2D projective images. These images are generated by relative motion between this set of objects and a set of ten fanbeam X-ray sources and sensors, with their viewing axes suitably distributed in 2D angular space. *** Findings – The method entails a radiation dosage several orders of magnitude lower than CT, and requires far less computational power. Experimental results are given to illustrate the capability of the technique *** Practical implications – The substantially lower cost of the method and, more particularly, its dramatically lower irradiation make it relevant to many applications precluded by current techniques *** Originality/value – The method can be used in many applications such as aircraft hold-luggage screening, 3D industrial modelling and measurement, and it should also have important applications to medical diagnosis and surgery.

Punk, Politics and British (fan)zines, 1974-84:'While the world was dying, did you wonder why?

This article recovers and contextualizes the politics of British punk fanzines produced in the late 1970s and early 1980s. It argues that fanzines – and youth cultures more generally – provide a contested cultural space for young people to express their ideas, opinions and anxieties. Simultaneously, it maintains that punk fanzines offer the historian a portal into a period of significant socio-economic, political and cultural change. As well as presenting alternative cultural narratives to the formulaic accounts of punk and popular music now common in the mainstream media, fanzines allow us a glimpse of the often radical ideas held by a youthful milieu rarely given expression in the political arena.

A new genus and new species of fan worms (Polychaeta: Sabellidae) from Atlantic and Pacific Oceans-the formal treatment of taxon names as explanatory hypotheses

Members of Parasabella minuta Treadwell, 1941, subsequently moved to Perkinsiana, were collected during a survey of rocky intertidal polychaetes along the state of Sao Paulo, Brazil. Additional specimens, which are referred to two new species, were also found in similar habitats from the Bocas del Toro Archipelago, Caribbean Panama, and Oahu Island, Hawaii. A phylogenetic analysis of Sabellinae, including members of P. minuta and the two new species, provided justification for establishing a new generic hypothesis, Sabellomma gen. nov., for these individuals. Formal definitions are also provided for Sabellomma minuta gen. nov., comb. nov., S. collinae gen. nov., spec. nov., and S. harrisae gen. nov., spec. nov., along with descriptions of individuals to which these hypotheses apply. The generic name Aracia nom. nov., is provided to replace Kirkia Nogueira, Lopez and Rossi, 2004, pre-occupied by a mollusk.

D(s)D* Molecule as an Axial Meson

We use QCD sum rules to study the possible existence of a D(s)(D) over bar* - D(s)*(D) over bar molecule with the quantum number J(PC) = 1(++). We consider the contributions of condensates up to dimension eight and work at leading order in alpha(s). We obtain m(DsD*) = (3.96 +/- 0.10) GeVaround 100 MeV above the mass of the meson X(3872). The proposed state is a natural generalized state to the strangeness sector of the X(3872), which was also found to be consistent with a multiquark state from a previous QCD sum rule analysis.

Axial ligand influence on geometries, charge distributions and electronic structures of iron tetraazamacrocycle [Fe((II))TIM(X)(Y)](2+) complexes assessed by Density Functional Theory

We employed the Density Functional Theory along with small basis sets, B3LYP/LANL2DZ, for the study of FeTIM complexes with different pairs of axial ligands (CO, H(2)O, NH(3), imidazole and CH(3)CN). These calculations did not result in relevant changes of molecular quantities as bond lengths, vibrational frequencies and electronic populations supporting any significant back-donation to the carbonyl or acetonitrile axial ligands. Moreover, a back-donation mechanism to the macrocycle cannot be used to explain the observed changes in molecular properties along these complexes with CO or CH(3)CN. This work also indicates that complexes with CO show smaller binding energies and are less stable than complexes with CH(3)CN. Further, the electronic band with the largest intensity in the visible region (or close to this region) is associated to the transition from an occupied 3d orbital on iron to an empty pi* orbital located at the macrocycle. The energy of this Metal-to-Ligand Charge Transfer (MLCT) transition shows a linear relation to the total charge of the macrocycle in these complexes as given by Mulliken or Natural Population Analysis (NPA) formalisms. Finally, the macrocycle total charge seems to be influenced by the field induced by the axial ligands. (C) 2011 Elsevier Ltd. All rights reserved.

Scanlation - What Fan Translators of Manga Learn in the Informal Learning Environment

The present paper discusses two pilot studies carried out to see the possibility of the fan community of manga (Japanese comics), in which fan translators translate the original Japanese manga into English (which is called scanlation), functioning as an informal learning environment for the Japanese language learning and translator training. Two pilot studies consist of a) comparison of the original Japanese version with the scanlation and official translation, and b) comparison of the original Japanese version with two different versions of scanlation to see the translators’ level of Japanese language and the overall translation quality. The results show that in scanlation versions, there were numbers of inaccuracies which would prevent them to be treated as professional translation. Some of these errors are clearly caused by insufficient understanding of Japanese language by the translator. However, the pilot studies also suggested some interesting features of fan translation, such as the treatment of cultural references. The two pilot studies indicate that it is desirable to conduct further studies with more data, in order to confirm the results of present studies, and to see the possible relationship between the types of trnalsation errors found in scanlation and the particular type of Japanese language (informal, conversational) that could be learned from manga.

Fan fictions eller adaptioner? : Om Amy Heckerlings spelfilm Clueless (1996) och Debra White Smiths roman Amanda (2006) mot Jane Austens roman Emma (1815)

Det huvudsakliga syftet med min uppsats var att utifrån originalverket Emma (1815) avJane Austen kunna bedöma vad två verk som inspirerats av romanen bör klassificeras som.De två verken var romanen Amanda (2006) av författaren Debra White Smith ochspelfilmen Clueless (1995) av regissören Amy Heckerling. Till min hjälp har jag lästaktuell forskning inom de två termerna adaption och fanfiction och utifrån detta gjort enjämförande analys på verken. Resultatet blev oväntat vagt, det visade sig att begreppen lågnärmre varandra än vad jag trott från början. Båda verken kan till viss del ses som enadaption på originalverket, på samma sätt som de även kan ses som fanfiction. Slutsatsenär dock att de båda verken passar bäst in under termen profic, som är en underkategoriinom fanfiction där författaren/regissören tjänar pengar på sin modifikation och intepublicerat verket i exempelvis ett obetalt nätforum som hobbyaktivitet.

Fan Culture as an Informal Learning Environment : Presentation of a NGL project

Fan culture is a subculture that has developed explosively on the internet over the last decades. Fans are creating their own films, translations, fiction, fan art, blogs, role play and also various forms that are all based on familiar popular culture creations like TV-series, bestsellers, anime, manga stories and games. In our project, we analyze two of these subculture genres, fan fiction and scanlation. Amateurs, and sometimes professional writers, create new stories by adapting and developing existing storylines and characters from the original. In this way, a "network" of texts occurs, and writers step into an intertextual dialogue with established writers such as JK Rowling (Harry Potter) and Stephanie Meyer (Twilight). Literary reception and creation then merge into a rich reciprocal creative activity which includes comments and feedback from the participators in the community. The critical attitude of the fans regarding quality and the frustration at waiting for the official translation of manga books led to the development of scanlation, which is an amateur translation of manga distributed on the internet.  Today, young internet users get involved in conceptual discussions of intertextuality and narrative structures through fan activity. In the case of scanlation, the scanlators practice the skills and techniques of translating in an informal environment. This phenomenon of participatory culture has been observed by scholars and it is concluded that they contribute to the development of a student’s literacy and foreign language skills. Furthermore, there is no doubt that the fandom related to Japanese cultural products such as manga, anime and videogames is one of the strong motives for foreign students to start learning Japanese. This is something to take into pedagogical consideration when we develop web-based courses. Fan fiction and fan culture make it ​​possible to have an intensive transcultural dialogue between participators throughout the world and is of great interest when studying the interaction between formal and informal learning that puts the student in focus

"Men shit, hur fan har vi kunnat glömma bort det?" : Falu kommuns socialtjänsts arbete gällande prostitution

The purpose of this study was to examine whether and how the social services in the municipality of Falun is managing social work related to prostitution. It is a qualitative study based on three focus group interviews conducted in parts of the social services organization in the municipality of Falun. The empirical data collected was analyzed from an intersectional perspective. Several distinct findings emerged from the study. Social work against prostitution does not exist in the social services organization in the municipality of Falun. The organization possesses no procedures or guidelines for this kind of work, and no preventive work or cooperation with other organizations is carried out. It also emerged, that several social work officers had a stereotype image of who a potential sex- seller could be. This fact may influence who would be able to get any support from social services regarding to this social problem.

Engajamento com fan pages de marcas no Facebook: impacto da força do laço, homofilia e confiança

A literatura de relacionamento do consumidor com a marca tem reconhecido a importância do ambiente virtual como ferramenta eficaz para a promoção da marca. Este espaço permitiu uma maior proximidade e estreitamento das relações com os diversos públicos das empresas ao potencializar as funções do marketing, o que levou as empresas a criarem fan pages de marca a fim de promover maior interação e incrementar o relacionamento com os stakeholders. Esta dissertação tem como objetivo verificar o impacto da força do laço e da homofilia na confiança em uma fan page de marca, e o impacto da confiança no engajamento com esta fan page. Para atender a este objetivo, a pesquisa se deu em duas etapas: uma primeira fase qualitativa e uma segunda fase quantitativa. Na primeira fase, esta pesquisa identifica a unidade de análise dos conceitos e gera itens para a mensuração da força do laço, homofilia, confiança e engajamento, por meio da revisão de literatura e nove entrevistas com seguidores de fan pages de marcas. A segunda fase verifica, por meio de uma survey com 688 seguidores de uma fan page, o impacto destes conceitos no engajamento. As entrevistas foram analisadas por meio da análise de conteúdo, enquanto que os dados da survey e a rede nomológica foram analisados pela modelagem de equações estruturais. Os resultados da primeira fase indicam que os consumidores tratam a fan page como unidade de análise dos conceitos e forneceram itens satisfatórios para a mensuração dos conceitos e suas dimensões. Já os resultados da segunda fase dão suporte a rede nomológica testada, indicando uma associação positiva da força do laço e homofilia com a confiança, e da confiança com o engajamento com fan pages de marcas.

Qualidade física e fisiológica de semente de soja colhida com sistema de trilha axial sob diferentes velocidades de operação e rotações do cilindro trilhador

A colheita mecanizada é ferramenta fundamental no processo produtivo das grandes culturas; se não for realizada adequadamente, poderá resultar em danos mecânicos severos às sementes, acarretando, prejuízos significativos na colheita, particularmente devido à redução da qualidade. Visando a avaliar os danos causados na colheita mecanizada de soja, o presente trabalho teve como objetivo estudar o efeito do sistema de trilha axial sobre a percentagem de bandinhas, impurezas e sementes quebradas de soja cv. M-Soy 8001, em função da velocidade de trabalho e rotação do cilindro trilhador. O delineamento experimental utilizado foi o inteiramente casualizado, em parcelas subdivididas, avaliando-se duas rotações do cilindro trilhador (400 e 500 rpm) e três velocidades de operação (3,5; 4,5 e 5,5 km h-1), com três repetições. Os resultados obtidos indicam que as combinações de velocidade de operação e rotações do cilindro de trilha avaliadas não afetam as variáveis vigor, impurezas, bandinha, emergência em areia e índice de velocidade de germinação e que o aumento da rotação de 400 para 500 rpm ocasiona o aumento de sementes quebradas.

Power performance evaluation of an electric home fan with triac-based automatic speed control system

In order to provide a low cost system of thermal comfort, a common model of home fan, 40 cm diameter size, had its manual four-button control system replaced by an automatic speed control. The new control system has a temperature sensor feeding a microcontroller that, by using an optic coupling, DIAC or TRIAC-based circuit, varies the RMS value of the fan motor input voltage and its speed, according to the room temperature. Over a wide range of velocity, the fan net power and the motor fan input power were measured working under both control system. The temperature of the motor stator and the voltage waveforms were observed too. Measured values analysis showed that the TRIAC-based control system makes the fan motor work at a very low power factor and efficiency values. The worst case is at low velocity range where the higher fan motor stator temperatures were registered. The poor power factor and efficiency and the harmonics signals inserted in the motor input voltage wave by the TRIAC commutation procedure are correlated.

Absence of gluonic components in axial and tensor mesons

A quarkonium-gluonium mixing scheme previously developed to describe the characteristic of the pseudoscalar mesons is applied to axial and tensor mesons. The parameters of the model are determined by fitting the eigenvalues of a mass matrix. The corresponding eigenvectors give the proportion of light quarks, strange quarks and glueball in each meson. However, the predictions of the model for the branching ratios and electromagnetic decays are incompatible with the experimental results. These results suggest the absence of gluonic components in the states of axial and tensor isosinglet mesons analyzed here.
