Authoring Tool for Location-based Learning Experiences

In this paper, we present some features of our in-situ indoor-outdoor authoring tool for location-based learning experiences. For example, how to reuse locations in different experiences or how to design from scratch in places without any location sensing mechanisms. In addition, we describe some features in which we are working on. We expect to create a space for discussion about these kind of tools and to reflect on the products created with them

Authoring Tool for Location-Aware Experiences

In this paper, we present an approach to create location-aware experiences. We use the concept of separation of concerns to represent the content layer and the location layer. This separation allows reusing the layers independently one of each other. The focus of this paper is to provide an end-user tool to create location-aware applications in-situ. By using our tool, the location-aware experiences can be defined in both indoor and outdoor spaces. We present an example of how our tool is used and we describe some discussion points that have occurred to us while defining a tool with these characteristics.Publicado en: NHT '15 Proceedings of the 2015 Workshop on Narrative & Hypertex

Combing Location-Aware Applications with in-situ Actors Performances

In this paper we present a model to define location-aware experiences having its different aspects (contents, location, etc) decoupled one from another. We have created an application following this model, which is also combined with actors’ performances. This application defines three relevant locations inside a specific building. By reading a QR-code the user indicates that he/she has arrived at one of those locations. In that moment, the application triggers some questions related to the actors’ performances. Hence, the user is required to see all the plays in order to be able to answer such questions. The application assists the user in moving throughout the different locations. We present the evaluation of this application and then we discuss interesting aspects that have shown up as a result of the in-situ evaluation of this application.Publicado en: NHT '15 Proceedings of the 2015 Workshop on Narrative & Hypertex

Desarrollo multiplataforma de aplicaciones móviles combinadas con el uso de beacons

En este trabajo se presenta la exploración de dos APIs de beacons existentes, una para PhoneGap y otra para React Native. Para esta exploración, se desarrollaron dos aplicaciones móviles, una en PhoneGap y otra en React Native; las cuales usan estas APIs para detectar la proximidad a los beacons, al entrar en la proximidad de un beacon, se brinda en pantalla la información del mismo. Se detallan distintas características de estas aplicaciones desarrolladas, haciendo hincapié en el análisis comparativo de estos desarrollos respecto a lo que provee cada API. Además, el trabajo presenta un espacio de discusión para analizar las lecciones aprendidas en la exploración realizada, en pos de contribuir a la temática relacionada al desarrollo de tipo de aplicaciones.Eje: X Workshop Innovación en Sistemas de Software (WISS

Measurements of the charge asymmetry in top-quark pair production in the dilepton final state at s √ =8 TeV with the ATLAS detector

Measurements of the top-antitop quark pair production charge asymmetry in the dilepton channel, characterized by two high-pT leptons (electrons or muons), are presented using data corresponding to an integrated luminosity of 20.3  fb−1 from pp collisions at a center-of-mass energy s√=8  TeV collected with the ATLAS detector at the Large Hadron Collider at CERN. Inclusive and differential measurements as a function of the invariant mass, transverse momentum, and longitudinal boost of the tt¯ system are performed both in the full phase space and in a fiducial phase space closely matching the detector acceptance. Two observables are studied: AℓℓC based on the selected leptons and Att¯C based on the reconstructed tt¯ final state. The inclusive asymmetries are measured in the full phase space to be AℓℓC=0.008±0.006 and Att¯C=0.021±0.016, which are in agreement with the Standard Model predictions of AℓℓC=0.0064±0.0003 and Att¯C=0.0111±0.0004

Study of the B-c(+) -> J/psi D-s(+) and Bc(+) -> J/psi D-s*(+) decays with the ATLAS detector

The decays B-c(+) -> J/psi D-s(+) and B-c(+) -> J/psi D-s*(+) are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb(-1) of pp collisions collected at centre-of-mass energies root s = 7 TeV and 8 TeV, respectively. Signal candidates are identified through J/psi -> mu(+)mu(-) and D-s(()*()+) -> phi pi(+)(gamma/pi(0)) decays. With a two-dimensional likelihood fit involving the B-c(+) reconstructed invariant mass and an angle between the mu(+) and D-s(+) candidate momenta in the muon pair rest frame, the yields of B-c(+) -> J/psi D-s(+) and B-c(+) -> J/psi D-s*(+), and the transverse polarisation fraction in B-c(+) -> J/psi D-s*(+) decay are measured. The transverse polarisation fraction is determined to be Gamma +/-+/-(B-c(+) -> J/psi D-s*(+))/Gamma(B-c(+) -> J/psi D-s*(+)) = 0.38 +/- 0.23 +/- 0.07, and the derived ratio of the branching fractions of the two modes is B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi D-s(+) = 2.8(-0.8)(+1.2) +/- 0.3, where the first error is statistical and the second is systematic. Finally, a sample of B-c(+) -> J/psi pi(+) decays is used to derive the ratios of branching fractions B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi pi(+) = 3.8 +/- 1.1 +/- 0.4 +/- 0.2 and B-Bc+ -> J/psi D-s*+/B-Bc+ -> J/psi pi(+) = 10.4 +/- 3.1 +/- 1.5 +/- 0.6, where the third error corresponds to the uncertainty of the branching fraction of D-s(+) -> phi(K+ K-)pi(+) decay. The available theoretical predictions are generally consistent with the measurement
