SuSoftPro: Sustainability Profiling for Software
2018 IEEE 26th International Requirements Engineering Conference (RE), 2018Co-Authors: Ahmed D. Alharthi, Maria Spichkova, Margaret HamiltonAbstract:The paper presents a SuSoftPro tool for requirement engineers to analyse the requirements' impacts on system sustainability. To perform the analysis of system sustainability, the tool provides quantitative questionnaires for rating high-level requirements within sustainability dimensions via a Fuzzy Rating Scale method. Stakeholders' responses are analysed by applying Technique for Order Preference by Similarity to Ideal Solution. The tool presents sustainability as a five-star rating label, a visualisation of the degree for sustainability dimensions, and a Bar Graph that illustrates the sustainability level.

research of doa estimation based on single mems vector hydrophone
Sensors, 2009Co-Authors: Wendong Zhang, Ling Gang Guan, Kai Rui Zhang, Guojun Zhang, Jianping WangAbstract:The MEMS vector hydrophone is a novel acoustic sensor with a "four-beam- cilia" structure. Based on the MEMS vector hydrophone with this structure, the paper studies the method of estimated direction of arrival (DOA). According to various research papers, many algorithms can be applied to vector hydrophones. The beam-forming approach and Bar Graph approach are described in detail. Laboratory tests by means of the a standing-wave tube are performed to validate the theoretical results. Both the theoretical analysis and the results of tests prove that the proposed MEMS vector hydrophone possesses the desired directional function.

Workload and stress in vigilance: the impact of display format and task type.
American Journal of Psychology, 2020Co-Authors: James L. SzalmaAbstract:: Signal salience was manipulated using configural and object displays to examine their effects on the performance, workload, and stress of vigilance. Improving performance and reducing the workload and stress of vigilance are crucial concerns. Signal salience improves performance and reduces stress, but to date there have been no salience manipulations using configural displays in a vigilance task. Two task types (individual variable monitoring and midpoint identification) and 3 display formats (Bar Graph-different baselines, Bar Graph-common baseline, and a polygon Graph display) were examined. Configural displays improved performance in the midpoint identification task but not in the individual variable monitoring task. Workload depended on the form of display features (Bar Graph vs. polygon). Stress increased across all conditions, but task and display format did not affect stress. The midpoint identification task was associated with more emotion-focused and avoidant coping. Increasing signal salience in a vigilance task using configural displays with emergent features or physical contours can improve performance and reduce the decrement. These displays may not reduce the stress of vigilance or encourage task-focused coping. Therefore, there may be hidden costs to vigilance performance even when highly salient configural displays are used.

Workload and Stress of Configural Displays in Vigilance Tasks
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2002Co-Authors: James L. SzalmaAbstract:The workload and stress associated with corrfigural displays in two vigilance tasks were investigated. Two kinds of configural displays were employed: A Bar Graph display and an object display. A non-configural Bar Graph display served as a control group. Relative to the non-configural display, both configural displays improved performance in a task requiring integration of information, but were not significantly different from the control group in a task requiring focused attention to display elements. The object display reduced workload in both tasks, but the Bar Graph configural display did not. Results showed a complex pattern of association/dissociation of workload with performance. Self reports of stress revealed that the tasks were stressful but that configural displays did not reduce the stress of either task.

Heart and respiratory rate detection on a bathroom scale based on the ballistocardiogram and the continuous wavelet transform
2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010Co-Authors: Sonia Gilaberte, Joan Gómez-clapers, Ramon Casanella, Ramon Pallas-arenyAbstract:BallistocardioGraphy is a non-invasive technique that yields information about the cardiovascular system that is not available in other external signals such as the electrocardiogram (ECG). In the last years, several research groups have obtained the ballistocardiogram (BCG) by using instrumentation methods simpler than those available in the 1950s and that did not progress because of their complexity as compared to ultrasound and other noninvasive techniques that are in common use nowadays. We describe a novel method for real-time robust heart- (HR) and respiratory- (RR) rate detection from a subject that stands on a common electronic bathroom scale. BCG signals from the scale are wirelessly sent to a PC where algorithms based on the continuous wavelet transform (CWT) extract the HR and the RR. HR results are compared to those obtained from the ECG. To better assess the RR results, subjects have been asked to synchronize their breathing rate to an on-screen Bar-Graph set at a constant rate of breaths per minute. This method to obtain the heart and respiratory rates is simple, compact, non-invasive and passive, and can be applied to any person able to stand on an electronic weighing scale, even if wearing shoes.
