How do archaeologists work? A multimedia digital object to learn their investigation process
No full textThe aim of the CHAT ("Cultural Heritage fruition & e-learning applications of new Advanced (multimodal) Technologies") research project was to provide on smartphones context-sensitive multimedia services accessible through several interaction modalities. The multimedia content of such services was implemented as Digital Objects managed by the Fedora web service. In this paper, we present a multimedia digital object that, through images, videos, 3D reconstructions, sounds, informs people about the scientific value of the archaeological investigation and about the complexity of the overall archaeological research process. Archaeologists follow a rigorous method, called stratigraphic excavation, to reconstruct the past civilizations lifestyles. People tend to think that the archaeologist work consists only in the excavation and research of valuable elements, while it has its scientific rigor. By exploiting the CHAT infrastructure, the multimedia digital object about the archaeologist work can be accessed in difTerent context on several device

Introducing Energy Efficiency into SQALE
No full textEnergy Efficiency is becoming a key factor in software development, given the sharp growth of IT systems and their impact on worldwide energy consumption. We do believe that a quality process infrastructure should be able to consider the Energy Efficiency of a system since its early development: for this reason we propose to introduce Energy Efficiency into the existing quality models. We selected the SQALE model and we tailored it inserting Energy Efficiency as a sub-characteristic of efficiency. We also propose a set of six source code specific requirements for the Java language starting from guidelines currently suggested in the literature. We experienced two major challenges: the identification of measurable, automatically detectable requirements, and the lack of empirical validation on the guidelines currently present in the literature and in the industrial state of the practice as well. We describe an experiment plan to validate the six requirements and evaluate the impact of their violation on Energy Efficiency, which has been partially proved by preliminary results on C code. Having Energy Efficiency in a quality model and well verified code requirements to measure it, will enable a quality process that precisely assesses and monitors the impact of software on energy consumptio
Definition, implementation and validation of energy code smells: an exploratory study on an embedded system
No full textOptimizing software in terms of energy efficiency is one of the challenges that both research and industry will have to face in the next few years.We consider energy efficiency as a software product quality characteristic, to be improved through the refactoring of appropriate code pattern: the aim of this work is identifying those code patterns, hereby defined as Energy Code Smells, that might increase the impact of software over power consumption. For our purposes, we perform an experiment consisting in the execution of several code patterns on an embedded system. These code patterns are executed in two versions: the first one contains a code issue that could negatively impact power consumption, the other one is refactored removing the issue. We measure the power consumption of the embedded device during the execution of each code pattern. We also track the execution time to investigate whether Energy Code Smells are also Performance Smells. Our results show that some Energy Code Smells actually have an impact over power consumption in the magnitude order of micro Watts. Moreover, those Smells did not introduce a performance decreas
Advanced interaction paradigms to define smart visit experiences in the internet of things era
No full textThe growing spread of smart objects is changing the way humans interact with technologies since the interaction they propose is more and more physical and less virtual. From an HCI perspective, one of the most interesting aspects regards how non-technical end users can program the behavior of such smart objects. This poster presents an ongoing project on three novel interaction paradigms that support the creation of smart visit experiences. Copyright is held by the author/owner(s)
