abstract = {Transmedia Stories are becoming an increasingly important technique for the tourism industry. They are successful tools to engage, inspire and gather audiences online and offline. In this article, we describe the design, implementation and evaluation of Fragments of Laura, a bespoke Transmedia Storytelling (TS) experience designed to involve visitors in developing knowledge and awareness about the cultural and natural heritage of Madeira Island. Fragments of Laura (FoL) is composed of two interconnected components: a Location-Aware Multimedia Story, and a Hypermedia Platform populated with locally collected testimonies and interviews. Results from the extensive evaluation of Fragments of Laura, highlights the potential of interactive multimedia, TS in particular, in engaging tourists with the destination values and community. Our contribution is twofold, on one hand we extend on the state of the art of multimedia interactive storytelling, with the description of the Fragments of Laura TS artifact. On the other hand, results from FoL evaluation highlight how the artifact impacts on the tourism experience its implications for the design of future tourism driven TS experiences.},

abstract = {This paper investigates how the concept of score has been used in the NIME community. To this end, we performed a systematic literature review of the NIME proceedings, analyzing papers in which scores play a central role. We analyzed the score not as an object per se but in relation to the users and the interactive system(s). In other words, we primarily looked at the role that scores play in the performance ecology.  For this reason, to analyze the papers, we relied on ARCAA, a recent framework created to investigate artifact ecologies in computer music performances. Using the framework, we created a scheme for each paper and clustered the papers according to similarities. Our analysis produced five main categories that we present and discuss in relation to literature about musical scores.},

We discuss the formulation of an environmental statement for the conference as well as the initiation of a NIME Eco Wiki containing information on environmental concerns related to the creation of new musical instruments. We outline a number of these concerns and, by systematically reviewing the proceedings of all previous NIME conferences, identify a general lack of reflection on the environmental impact of the research undertaken. Finally, we propose a framework for addressing the making, testing, using, and disposal of NIMEs in the hope that sustainability may become a central concern to researchers.},

abstract = {INTRODUCTION: We present an audience study investigating the impact of different technologies to create visuals in dance performances.

OBJECTIVES: We investigated four conditions: motion capture, sensors, camera image, and minimal interaction; and four variables: how much did the audience perceive a connection between the body and the visuals; the visuals as merely copying the dancer; how much distracting were the visuals; and how much did the audience enjoy the visuals.

METHODS: We used a questionnaire to collect data. We analyzed it using Friedman’s test, and Spearman’s correlation test.

RESULTS: The audience perceived a stronger connection in the camera condition, but in the same condition, visuals tend to be merely copying the dancer. We also suggest that the perceived connection has a positive correlation with enjoyment, while distraction has a negative correlation.

CONCLUSION: Our results help to highlight the impact that different technology have on live visuals for dance.},

abstract = {This paper reports on the different engineering, social and financial challenges behind the building and deploying electric energy monitoring and eco-feedback technology in real-world scenarios, which despite being relevant to the research community are seldom reported in the literature. The objectives of this paper are two-fold: First, discuss the technical and social constraints of real-world deployments. This includes, for example, hardware and software requirements, and issues related to security and intrusiveness of the monitoring solutions. Second, identify and understand the costs associated with developing and deploying such systems. These include hardware costs and consumed energy. To this end, we rely on over five years of experience developing and improving a non-intrusive energy monitoring research platform to enable the deployment of long and short-term studies of eco-feedback technology. During this time, two versions of that platform were deployed in 50 homes for periods that lasted between 6 and 18 consecutive months. By iteratively developing and deploying our sensing and eco-feedback infrastructures, we managed to build upon previous findings and lessons learned to understand how to create, deploy, and maintain such systems. Concurrently, we gained insights regarding what are some of the most relevant costs associated with running such experiments.},

Particularly, we explore two of the most important markets in the Latin American region (i.e., Brazil and Mexico), which went through similar economic downturns, but different social experiences in recent years. Survey data from Kantar Media’s Target Index (TGI) Latina service —the most extensive market study in the region— and qualitative data from a second online survey conducted through eCGlobal online panel have been analyzed. Data reveals that the rush to cancel cable or satellite television services did not occur at the high rates expected and were not remarkably influenced by social class, as they were by education factors.},

abstract = {
This paper describes recent work on the development of a wireless-based remote monitoring system for household energy consumption and generation in Madeira Island, Portugal. It contains three different main sections: (1) a monitoring system for consumed and produced energy of residencies equipped with photovoltaic (PV) systems, (2) developing a tool to predict the electricity production, (3) and proposing a solution to detect the PV system malfunctions. With the later tool, the user (owner) or the energy management system can monitor its own PV system and make an efficient schedule use of electricity at the consumption side. In addition, currently, the owners of PV systems are notified about a failure in the system only when they receive the bill, whereas using the proposed method conveniently would notify owners prior to bill issue. The artificial neural network was employed as a tool together with the hardware-based monitoring system which allows a daily analysis of the performance of the system. The comparison of the predicted value of the produced electricity with the actual production for each day shows the validity of the method.

Specific information about types of appliances and their use in a specific time window could help determining in details the electrical energy consumption information. However, conventional main power meters fail to provide any specific information. One of the best ways to solve these problems is through non-intrusive load monitoring, which is cheaper and easier to implement than other methods. However, developing a classifier for deducing what kind of appliances are used at home is a difficult assignment, because the system should identify the appliance as fast as possible with a higher degree of certainty. To achieve all these requirements, a convolution neural network implemented on hardware was used to identify the appliance through the voltage and current (V-I) trajectory. For the implementation on hardware, a field programmable gate array (FPGA) was used to exploit processing parallelism in order to achieve optimal performance. To validate the design, a publicly available Plug Load Appliance Identification Dataset (PLAID), constituted by 11 different appliances, has been used. The overall average F-score achieved using this classifier is 78.16% for the PLAID 1 dataset. The convolution neural network implemented on hardware has a processing time of approximately 5.7 ms and a power consumption of 1.868 W.

abstract = {One of the greatest challenges presented by the writings of Flann O’Brien is how to place them. For some he is the peer of Joyce and Beckett; for others his work is modernist pastiche; still others regard him as a reactionary satirist; while for another group he is the forerunner of American postmodernism. His work is often loosely labelled “surreal” or “absurd.” Yet O’Brien’s work is rarely read as avant-garde per se. This essay attempts to gain a new understanding of his oeuvre by reading a particular sliver of it – his manifestos – in the context of the historical avant-garde in Europe. Like many writers of his generation and the one previous, O’Brien wrote manifestos. One example is the founding editorial of the “anti-magazine” Blather (1934), whose “sardonic laugh” echoes the manifestos – or “anti-manifestos” – of Vorticism and Dada. The manifesto of intertextuality in At Swim-Two-Birds (1939), meanwhile, is more complex: while it appears to be in some ways a sincere statement about the novel as a whole, it is also intensely ironic and self-mocking. But that only deepens its relation to the manifestos of the preceding decades, which frequently undercut their own purpose in the midst of their performance.},

abstract = {
Non-intrusive load monitoring (also known as NILM or energy disaggregation) is the process of estimating the energy consumption of individual appliances from electric power measurements taken at a limited number of locations in the electric distribution of a building. This approach reduces sensing infrastructure costs by relying on machine learning techniques to monitor electric loads. However, the ability to evaluate and benchmark the proposed approaches across different datasets is key for enabling the generalization of research findings and consequently contributes to the large-scale adoption of this technology. Still, only recently researchers have focused on creating and standardizing the existing datasets in order to deliver a single interface to run NILM evaluations. Furthermore, there is still no consensus regarding, which performance metrics should be used to measure and report the performance of NILM systems and their underlying algorithms. This paper provides a review of the main datasets, metrics, and tools for evaluating the performance of NILM systems and technologies. Specifically, we review three main topics: (a) publicly available datasets, (b) performance metrics, and (c) frameworks and toolkits. The review suggests future research directions in NILM systems and technologies, including cross-datasets, performance metrics for evaluation and generalizable frameworks for benchmarking NILM technology.
