A Universal Model-Based Solution for Describing and Handling Errors
2011
Before the system is on the way to end users’ desktops, developers should not forget about error messages their system might display. That is also true for systems with models inside. Is there a model-based solution for describing and handling errors in a universal way? We say ‘Yes’, and we show how the meta-meta level of abstraction aids here. Having error types described, particular errors are simply placed into the model repository (when needed), and the error handling mechanism automatically handles and displays them in an appropriate way.
Perceptions of Healthcare Service End Users
2016
The main objective of this study was to compare users’ perception and evaluation of both public and private healthcare services, distinguishing between primary and specialty care, with a cross-cultural approach in two Mediterranean countries: Italy and Spain. Within an exploratory approach and following a descriptive aim, we have conducted a quantitative methodology: after a literature review about health marketing and health management, we have developed a questionnaire and collected end users’ perceptions in both countries. Results highlight different aspects shaping the multidimensional healthcare service, such as the waiting lists, their experienced sensations, word-of-mouth (WOM) rele…
Decision-making Tool for Moving from 3-axes to 5-axes CNC Machine-tool
2016
Abstract Nowadays most of the parts within machine-building industry are machines on CNC machine-tools. According to their mechanical and kinematic structure, CNC machine-tools can be divided into 3-axes and 5-axes ones. Each type has its advantages and drawbacks and choosing between them could be a very difficult process. This paper presents a decision support tool for aiding the process of selecting between using and/or buying either a 3-axes CNC milling machine or a 5-axes milling machine, based upon fuzzy logic. The tool was built using the Fuzzy Logic Toolbox and the fuzzy graphical user interface (GUI) within Matlab software package.
The Human Modes of Being in Investigating User Experience
2008
An important challenge for interaction designers is to understand factors that shape user experience, and novel approaches are being developed to establish user experience as a specific field of research. Previous attempts to provide a comprehensive theory of user experience have focused on analyzing sensations and emotions as well as perceptions and behaviors. A holistic view of human experience is still lacking. I argue that a holistic view of the human being is needed to provide the appropriate theoretical foundations for user experience analyses in diverse contexts. In this chapter I introduce a theoretical framework for understanding human experience, and discuss how such a holistic vi…
User Activity Recognition for Energy Saving in Smart Homes
2015
Abstract Energy demand in typical home environments accounts for a significant fraction of the overall consumption in industrialized countries. In such context, the heterogeneity of the involved devices, and the non negligible influence of the human factor make the optimization of energy use a challenging task; effective automated approaches must take into account basic information about users, such as the prediction of their course of actions. Our proposal consists in learning customized structural models for common user activities for predicting the trend of energy consumption; the approach aims to lower energy demand in the proximity of predicted peak loads so as to keep the overall cons…
A microcontroller-based portable electrocardiograph recorder.
2004
We describe a low cost portable Holler design that can be implemented with off-the-shelf components. The recorder is battery powered and includes a graphical display and keyboard. The recorder is capable of acquiring up to 48 hours of continuous electrocardiogram data at a sample rate of up to 250 Hz.
A Banki–Michell turbine for in-line water supply systems
2017
The design of a novel Banki-Michell type turbine, to be located in existing water pipelines, is proposed. The turbine has a very efficient diffuser which allows the turbine to be compact and, most important, to have in-line flanges for minimal piping modifications at existing sites. This turbine combines a simple geometry with stable efficiency in a wide range of water discharges. The design procedure estimates the outer diameter of the impeller, its width and the geometry of the diffuser. A series of experimental tests has been carried out to measure the efficiency of the proposed turbine prototype. The turbine was tested in two different configurations, with and without rotational velocit…
A Graphical User Interface as a DSS Tool for GHG Emission Estimation from Water Resource Recovery Facilities
2017
A Grafical User Interface (GUI) for the greenhouse gas (GHG) emissions from WWTPs based on four models aimed at quantifying the gas emissions from the aerated tanks (i.e. CAS and MBR reactor), aerobic digesters, secondary clarifiers and anaerobic digesters have been englobed in a GUI in order to provide a valid decision support system (DSS) to the practitioners. The GUI allows to estimate such emissions for the different WWTP phases considered. The GUI has been developed on MATLAB platform and provides as output the GHG emissions in terms of CO2 and N2O fluxes.
Towards a cyber-physical era: soft computing framework based multi-sensor array for water quality monitoring
2018
Abstract. New concepts and techniques are replacing traditional methods of water quality parameter measurement systems. This paper introduces a cyber-physical system (CPS) approach for water quality assessment in a distribution network. Cyber-physical systems with embedded sensors, processors and actuators can be designed to sense and interact with the water environment. The proposed CPS is comprised of sensing framework integrated with five different water quality parameter sensor nodes and soft computing framework for computational modelling. Soft computing framework utilizes the applications of Python for user interface and fuzzy sciences for decision making. Introduction of multiple sen…
Unremarkable experiences - Designing the user experience of elevators
2014
Elevators enable people and goods to be transported to great heights at substantial speeds.The feats required technologically for suspension, movement, controls and safety are no less than remarkable. This is increasingly so when considering the competing new heights of skyscrapers. Although technological accomplishments are becoming ever more extraordinary, for the sake of those using the technologies, there is also the need to counter this remarkableness and consider the unremarkable as an experiential design goal. Discourse in user experience (UX) has mainly focused on designing for positive, affective and memorable experiences. However, in the case of utilitarian technologies such as el…
