The Culture on the Palm of Your Hand: How to Design a User Oriented Mobile App for Museums
2014
The increased usage of mobile apps has a great potential for the tourism industry. Through the use of mobile apps, web portals and social media may allow a fast and wide diffusion of awareness for museum and attract a large number of visitors, thus increasing the value of their image, with moderate investments. The aim of this chapter is to identify the key factors as antecedents of customer satisfaction for the design of a mobile app for a museum. To this aim, the authors use the Kano model that allows categorizing service attributes according to how they are perceived by customers and estimating their impact on customer satisfaction. This model is adopted in order to identify express and …
Table Top Augmented Reality System for Conceptual Design and Prototyping
2011
The AugmenTable is a desktop augmented reality workstation intended for conceptual design and prototyping. It combines a thin form factor display, inexpensive web cameras, and a PC into a unique system that enables natural interaction with virtual and physical parts. This initial implementation of the AugmenTable takes advantage of the popular open source augmented reality software platform ARToolkit to enable manual interaction with physical parts, as well as interaction with virtual parts via a physically marked pointer or a color-marked fingertip. This paper describes similar previous work, the methods used to create the AugmenTable, the novel interaction it affords users, and a number o…
Promotion of polygeneration for buildings applications through sector- and user-oriented “high efficiency CHP” eligibility criteria
2014
Abstract The eligibility criteria adopted to assess polygeneration plants as “highly efficient” can play a determinant role in favouring or discouraging the market growth of polygeneration systems, especially for buildings applications where economic viability is often more difficult to achieve. Based on the current European framework, in this paper the opportunity to adopt sector- and user-oriented criteria is discussed. After having identified three buildings with different uses (a large hotel, a hospital and an office building), the optimal lay-out and operation strategy of a polygeneration plant serving each building is determined; then, ex-post processing of economic and energetic resu…
A Low-cost, Real-time Monitoring System for PV Plants based on ATmega 328P-PU Microcontroller
2015
This paper presents a real-time monitoring system for PV power plants based on a microcontroller Atmega328P-PU. The proposed system, whose performances can be relatively close to those achieved with commercial monitoring systems, is simple, low-cost and open source technology-based. In addition, a user interface, capable to communicate through a wireless network by using a standard communication protocol IEEE 802.15.1, is here presented. From the experimental tests described and discussed in this paper it is demonstrated that the proposed monitoring system provides, with adequate accuracy, all the information about the operating status of the PV plant, even during fault conditions.
Validation of the group nuclear safety climate questionnaire.
2013
Abstract Introduction Group safety climate is a leading indicator of safety performance in high reliability organizations. Zohar and Luria (2005) developed a Group Safety Climate scale (ZGSC) and found it to have a single factor. Method The ZGSC scale was used as a basis in this study with the researchers rewording almost half of the items on this scale, changing the referents from the leader to the group, and trying to validate a two-factor scale. The sample was composed of 566 employees in 50 groups from a Spanish nuclear power plant. Item analysis, reliability, correlations, aggregation indexes and CFA were performed. Results Results revealed that the construct was shared by each unit, a…
A New Web Interface for Distributed Control Systems: Application to the Chemical Monitoring of a Wort Fermentation Process
2006
A new web interface for rule net-based distributed control systems is proposed. It is applied to the monitoring of a chemical analysis system coupled with a wort fermentation process. A complete description of both the chemical and the informatics system is presented. This interface offers the possibility of accessing the process from any Internet-connected device (PC, PDA, etc.), using a standard browser as the only software required. The evolution of the results obtained in the FIA monitoring (and consequently of the process) can be analyzed by means of this interface; on the other hand, the process itself can be directly controlled through the modification of the different working parame…
The Steps of User-Centered Design in Health Information Technology Development: Recommendations from a PhD Research Study
2016
This study was carried out to explore the steps of User-centered Design in development of health information technology. The technology was developed in two research projects: the European Union project United4Health that created a collaborative telemedicine system for remote monitoring of Chronic Obstructive Pulmonary Disease and the Southern Norway regional project eHealth-extended Care Coordination that built an information system for coordination in inter-municipal health care teams. In both projects, the end-users were involved as active contributors in a User-centered Design process spanning from idea-generation until final deployment stages. This paper presents the steps in the User-…
Flat panel displays for medical monitoring systems
2005
Flat panel displays are ideal for demanding hospital and clinic applications like vital sign monitoring and bedside administration. They take up much less space than conventional monitors (CRT based) and can be wall-mounted, cart-mounted or used on a desk stand. User friendly interface demands easy to use input device, rotary position encoders and touch screen panels offers simplicity replacing bulky keyboards. This article will present an overview about today's medical monitoring systems tendencies, describing as an example, a custom medical monitoring module developed to be integrated in an assisted ventilation system.
Effect of Channel-Quality Indicator Delay on HSDPA Performance
2007
This paper evaluates the effect of the channel estimation inaccuracy on the performance of an HSDPA system. This study provides some results from system level simulations that have been conducted over a very complete dynamic simulator which models an HSDPA system full compliant with specifications. This emulator allows performing multi-user transmission and link adaptation with a limited modulation and coding scheme (MCS) selection based on the channel quality indicator (CQI) modes. Many factors such as the user equipment (UE) speed, the employed scheduling algorithm or the traffic load have been considered in the assessment. Moreover the intrinsic constraints of a WCDMA system like HSDPA h…
PAUT inspection of complex-shaped composite materials through six DOFs robotic manipulators
2015
The requirement to increase inspection speeds for the non-destructive testing (NDT) of composite aerospace parts is common to many manufacturers. The prevalence of complex curved surfaces in the industry provides significant motivation for the use of six-axis robots for the deployment of NDT probes in these inspections. The IntACom project, developed by TWI Technology Centre (Wales) and supported by a number of major aerospace partners and the Welsh government, has produced a prototype robotic NDT system. The prototype system is capable of inspecting complex-geometry composite components with great time savings. Two six-axis robotic arms deploy end effectors carrying phased array ultrasonic…
