Emotion in Motion: A Study of Music and Affective Response
No full textEmotion in Motion’ is an experiment designed to understand the emotional reaction of people to a variety of musical excerpts, via self-report questionnaires and the recording of electrodermal response (EDR) and pulse oximetry (HR) signals. The experiment ran for 3 months as part of a public exhibition, having nearly 4000 participants and over 12000 listening samples.
This paper presents the methodology used by the authors to approach this
research, as well as preliminary results derived from the self-report data and the
physiology
Barriers to Adopting Agile Practices when Developing Medical Device Software
No full textAgile methodologies such as XP and Scrum are founded upon the four values and twelve principles of agile software development. A software development project is only considered to be truly agile if these values and principles are followed. However, software developed for use in medical devices must be regulatory compliant and this can make the process of following a single agile methodology such as XP difficult to achieve. This paper outlines how we identified the barriers to agile adoption in the medical device software domain through performing a survey. These barriers include:lack of documentation; maintaining traceability; regulatory compliance; lack of up front planning and the process of managing multiple releases. Based on this research recommendations are also made as to how these barriers can be overcome

Software Process Improvement to assist Medical Device Software Development Organisations to comply with the amendments to the Medical Device Directive
Get PDFA recent revision to the European Medical Device Directive (MDD) 2007/47/EC made fourteen
amendments to the original directive (93/42/EEC). A number of these changes directly affect the development of software for use in healthcare. The most significant change in relation to medical device software development is that standalone software is now seen as an active medical device and should be developed following state of the art medical device software development processes. State of the art medical device software processes is understood within the industry as developing software in accordance with IEC 62304 and standards that are aligned with it. This paper identifies how changes to the MDD affect medical device software development companies and recommendations are made as to how medical device software development companies can conform to the latest regulatory requirements. Additionally, the paper provides an overview of how Medi SPICE is currently being developed to provide organisations with a single point of reference for the practices that should be implemented in order to produce regulatory compliant medical device software
Traceability-Why do it?
No full textTraceability of software artifacts, from requirements to design and through implementation and quality assurance, has long been promoted by the research and expert practitioner communities. However, evidence indicates that, with the exception of those operating in the safety critical domain, few software companies choose to implement traceability processes, in the most part due to cost and complexity issues.
This paper presents a review of traceability literature including the implementa-tion of traceability in real organizations. Through both analyzing case studies and research published by leading traceability researchers, this paper synthesiz-es the motivations of the organizations for implementing traceability. Given the importance of traceability in the regulated domain of safety critical software, the paper compares the motivations and benefits for organizations operating inside and outside of this domain.
Finally, based on an analysis of the disparate case studies, the paper re-assesses the value of traceability motivators for more widespread adoption by firms outside of the safety critical sector
The Emotion in Motion Experiment: Using an Interactive Installation as a Means for Understanding Emotional Response to Music
No full textn order to further understand our emotional reaction to music, a museum-based installation was designed to collect physiological and self-report data from people listening to music. This demo will describe the technical implementation of this installation as a tool for collecting large samples of data in public spaces. The Emotion in Motion terminal is built upon a standard desktop computer running Max/MSP and using sensors that measure physiological indicators of emotion that are connected to an Arduino. The terminal has been installed in museums and galleries in Europe and the USA, helping create the largest database of physiology and self-report data while
listening to music
Application of Remote Sensing techniques at Brú na Bóinne World Heritage Site, County Meath, Ireland
No full textResults from the first use of the Geophysical Exploration Equipment Platform (GEEP) in Ireland in carrying out a multi-sensor survey in the vicinity of a possible Neolithic passage tomb known as Site E in the Brú na Bóinne World Heritage Site. Brú na Bóinne, a UNESCO World Heritage Site, has been an important ritual, social and economic centre for thousands of years. Much research has been undertaken in the area, including large-scale excavations at the Neolithic passage tombs of Newgrange and Knowth. However we still lack an in-depth understanding of the site’s broad range of archaeological monuments, and the landscape and communities that shaped them. To date there has been no systematic large-scale use of ground geophysical techniques although a number of successful spatially discrete geophysical surveys have been carried out. The landscape has many large, open fields under pasture or tillage suitable for systematic large-scale ground geophysical survey. Such a survey, integrated with the interpretation of other available remote sensing data is an obvious next step in the investigation of this internationally important landscape. The evaluation was successful and the results from the GEEP dataset will be presented with a comparative study of data collected by traditional hand-carried magnetic gradiometry, earth resistance and magnetic susceptibility surveys
The Hill of Slane Archaeological Project (HoSAP) EF/HER/2011/68. Preliminary Survey Report 2012
No full textThe Hill of Slane Archaeological Project (HoSAP) was set up in 2010 as a way of exploring the archaeology, history and cultural heritage of this important but somewhat overlooked archaeological complex. The hilltop is the location of a number of important stone ruins, ecclesiastical in nature while is also the site of a significant motte castle as well as a possible prehistoric barrow. This preliminary report details the second phase of archaeological survey work which includes topographic survey, LiDAR analysis and geophysical survey. The main aims are firstly to gather data on the nature of the surviving monuments and secondly to identify low relief or subsurface traces related to these and other features in the comple
Effects of weather-related episodic events in lakes: an analysis based on high frequency data.
Get PDF1. Weather-related episodic events are typically unpredictable and their duration is often short. Abiotic and biological responses are often missed in routine monitoring. These responses are, however, now of particular relevance given projected changes in extreme weather conditions.
2. We present data from high frequency monitoring stations from lakes in Europe, North America and Asia that illustrate two classes of abiotic effects of weather events: (i) generally short-lived effects of storms on lake thermal structure and (ii) the more prolonged effects of high rainfall events on dissolved organic matter levels and water clarity. We further relate these abiotic effects to changes in dissolved oxygen or in chlorophyll a levels.
3. Three differing causes for weather-related decreases in surface dissolved oxygen levels were observed: (i) entrainment of anoxic water from depth, (ii) reduction in primary productivity, and (iii) increased mineralisation of organic carbon delivered from the catchment.
4. The duration of in-lake effects tended to be longer for events driven by weather conditions with a longer return period, that is, conditions which were relatively more severe and less frequent at a site. While the susceptibility of lakes to change was related in part to the severity of the meteorological drivers, the impacts also depended on site-specific factors in some cases.
5. The availability of high frequency data at these sites provided insight into the capacity of the lakes to absorb current and future pressures. Several of the changes we observed, including increases in carbon availability, decreases in PAR and increased disturbance, have the capacity to shift lakes towards an increased degree of heterotrophy. The magnitude and direction of any such change will, however, also depend on the magnitude and direction of climate change for a given location, and on lake and catchment characteristics
