For service-based applications which are composed of multiple independent third-parties, continuous monitoring is required to assure that runtime behavior of the systems complies with specified properties. However, most existing work only detects the violation while not consider how to enforce the properties so that the constraint can not be violated at runtime. To address this limitation, this paper...
LUSI (Lumpur Sidoarjo) mud volcano has been erupting solid and liquid materials for more than 7 years since its birth. The sudden nature of this phenomenon and land subsidence observed around the big hole requires immediate and precise management. Embankment built around it needs proper monitoring to observe the subsurface condition in order to avoid sudden failures. GPR monitoring, being non-destructive...
This paper presents a new computational algorithm for reliability inference with dynamic hybrid Bayesian network. It features a component-based algorithm and structure to represent complex engineering systems characterized by discrete functional states (including degraded states), and models of underlying physics of failure, with continuous variables. The methodology is designed to be flexible and...
This paper describes the findings on ‘flipping the classroom’ pedagogy for one selected topic in the Software Engineering module. A flipped classroom is a form of blended learning where the lecture is moved outside the classroom with the help of technology and learning activities are moved inside the classroom. The students typically watch instructional videos outside of the classroom but participate...
An irregular heartbeat is highly dangerous to an adult, and even more so to an unborn baby. Whether it is poor oxygenation or other more serious conditions, monitoring a fetus's heartbeat is necessary to determine any health issues. While current methodologies are well received from the general public, there is much room for improvement. A potential solution to the drawbacks of common measuring devices...
The use of online systems for assessments has become increasingly popular over the past decade. There is a general consensus that these systems have tremendous potential for enhancing teaching and learning even at the tertiary level. Nevertheless, most past studies on the use of online assessments have been focused on lower level or foundational courses that have larger class sizes while the adoption...
Precisely controlled blind via-holes were formed in multilayer substrates by an ultrafast laser. A LIBS detector integrated into the laser processing machine realizes the full potential of the ultrafast laser.
The Bioeconomy strategy fosters the integration of the agricultural, chemical, pulp and paper industries and the energy sector for obtaining sustainable bio-based materials and bioenergy. Basically all industrial sectors relying on biomass are facing economic burdens by resource competition. The cascade and coupled use stand as potential solutions for cross-sectoral cooperations to mutually enhance...
To solving the real-time material delivery problems from the warehouse to workstations of the mixed model automotive assembly line in accordance with the production cycle. The material flow of automotive assembly, type of material and the production characteristic were analyzed in order to feed material timely & properly. The material real-time delivery system based on field bus has been developed...
The paper presents results of research dealing with individual learning preferences and their reflection within the process of instruction at the Faculty of Informatics and Management, University of Hradec Kralove, Czech Republic. Learners' preferences in types of study materials, assignments, assessments, types of contact and approaches to teaching/learning reflecting individual learning patterns...
Electrical tree is recognized as one of the pre-breakdown phenomena that occurs in high voltage insulation material. In addition, under high divergent field, the electrical tree grows rapidly and severely which may cause the breakdown of insulation to occur. In view of foregoing, nano-filler was added into the base insulating materials to enhance their properties against the growth of electrical tree...
Complex engineering systems, such as nuclear processing systems, need to be closely monitored to meet given operational requirements. Previous work has developed diagnosers for detecting and counting occurrences of anomaly patterns (e.g., physical faults, facility misuse) in such systems within discrete event dynamic system (DEDS) framework. This work illustrates the application of this general methodology...
This article deals with the modeling of a strain-displacement transducer conceived for extending the FBG measurement range. The intrinsic fragility of the optical fiber limits their application to cases characterized by relatively small deformations. To extend the employ to the large displacement field (i.e. morphing applications), a dedicated device was conceived, constituted by a circular ring connected...
Air quality monitoring system that can monitor gas such as CO and SOx on ambient air in a real-time and can be accessed with internet line have been developed. Sensor element on this system is based on nano structured zinc oxide thin film synthesized using wet chemical route. Monitoring system is designed using arduino uno microcontroller as analog to digital converter, and ethernet shield for data...
This paper describes an engineering approach suitable for a service-oriented control and monitoring environment in the industrial manufacturing area. Recent and current research projects (http://www.socrades.eu and http://www.imc-aesop.eu) have focused on the concepts, opportunities, feasibility and required strategies for the effective application of service-oriented architectures in the manufacturing...
Micro-EDM (μEDM) milling is a well-established micro-manufacturing technique, which offers three-dimensional and flexible machining capabilities for structuring electrically conductive difficult-to-machine materials. There has been considerable progress in micro-manufacturing capabilities by μEDM in recent years. Nevertheless there still exist a few challenges in terms of process accuracy and efficiency,...
This paper describes an applications for supporting the cooperative learning by applying the Jigsaw method. Cooperative learning is the process which people gather in groups to teach each other what they know and understand. One of the famous method of cooperative learning is Jigsaw. But, using Jigsaw method need much time, hard to divide students into some groups and evaluation the learning process...
In order to monitor curing process of epoxy resin in real time, the system for cure monitoring is established based on Fiber Bragg Grating. First, a bare FBG, a FBG packaged with quartz capillary and an accurate resistance thermometer are closely stacked into a special mould. Then the mould is filled with mixture of epoxy resin and curing agent. Finally they are heated and cured together in the temperature-controlled...
This work describes preliminary steps towards nano-scale reservoir computing using quantum dots. Our research has focused on the development of an accumulator-based sensing system that reacts to changes in the environment, as well as the development of a software simulation. The investigated systems generate nonlinear responses to inputs that make them suitable for a physical implementation of a neural...
In order to monitor the agglomeration in gas-solid fluidized bed, the voiceprint characteristics should be accurately extracted. Acoustic signals created by the polymer impact on the inner bed wall of the fluidized bed reactor were monitored with pasting piezoelectric ceramic sensors on the outside wall of fluidized bed reactor, transmitting the charge with long shielded cables and audio sampling...
