Design And Characterization Of Automated Color Sensor System
2017
Abstract The paper presents a color sensor system that can process light reflected from a surface and produce a digital output representing the color of the surface. The end-user interface circuit requires only a 3-bit pseudo flash analog-to-digital converter (ADC) in place of the conventional/typical design comprising ADC, digital signal processor and memory. For scalability and compactness, the ADC was designed such that only two comparators were required regardless of the number of color/wavelength to be identified. The complete system design has been implemented in hardware (bread board) and fully characterized. The ADC achieved less than 0.1 LSB for both INL and DNL. The experimental r…
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…
Hardware-in-the-loop implementation for an active heave compensated drawworks
2012
Published version of an article published in the journal: Central European Journal of Engineering. Also available from the publisher at: http://dx.doi.org/10.2478/s13531-011-0062-1 This paper presents the setup and running of a hardware-in-loop (HIL) simulation for an active heave compensated (AHC) draw-works. A simulation model of the draw-works is executed on a PC to simulate the AHC draw-works with a physical PLC. The PLC (ET200S) is configured with a controller architecture that regulates the motor angular displacement and velocity through actuation of the servo valves. Furthermore, a graphical user interface is developed for operation of the AHC system. The HIL test allowed tuning of t…
Presenting a Multi-level Superstructure Optimization Approach for Mechatronic System Design
2010
Synergism and integration in the design process is what sets apart a Mechatronic System from a traditional, multidisciplinary system. However the typical design approach has been to divide the design problem into sub problems for each technology area (mechanics, electronics and control) and describe the interface between the technologies, whereas the lack of well-established, systematic engineering methods to form the basic set-off in analysis and design of complete mechatronic systems has been obvious. The focus of the current paper is therefore to present an integrated design approach for mechatronic system design, utilizing a multi-level superstructure optimization based approach. Finall…
From Extensity to Protensity in CAS: Adding Sounds to Icons
2009
Being aware of the gap between technological offers and user expectations, the paper aims to illustrate the necessity of anthropocentric designs ("user-pulled") and to reveal the dangers of current ICT designs ("technology-pushed"). Since the gap is deepened because of insufficient innovative use of new agent-oriented technology potential, an affordable manner to "invent new Computer-Aided x" application domains is proposed. To substantiate the approach, the domain must be challenging, easy to implement and "as humanist as possible": Computer-Aided Semiosis (CAS). On this background, the paper also presents a new and challenging concept in IT applied research, borrowed from psychology and m…
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…
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…
Experimental evaluation of an hybrid communication system architecture for smart grid applications
2015
In this paper a new communication system architecture is proposed for the development of a SCADA system which can remotely monitor and control intelligent electronic devices (IEDs) connected to the low voltage distribution networks, i.e low voltage smart meter (SM), interface protection devises (IPS). New distributed metering systems and interface devices, together with a proper communication infrastructure (HiperLAN and narrowband power line communication (NB-PLC) on low voltage network), have been developed to allow monitoring the whole power system and controlling the distributed generators of a Smart Grid also in the presence of harmonic distortions. In this way, the electrical energy d…
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…
