Model quality is one of the decisive factors that affect the performance of model-based controllers. However, the existing methods were devoted to the monitoring of the overall model quality, and didn't distinguish mismatch of the process model and the disturbance model. Aiming at this problem, this paper presents a new method for monitoring the quality of process model based on input and output data...
Software-Defined Networking (SDN) allows for fast reactions to security threats by dynamically enforcing simple forwarding rules as counter-measures. However, in classic SDN all the intelligence resides at the controller, with the switches only capable of performing stateless forwarding as ruled by the controller. It follows that the controller, in addition to network management and control duties,...
This article proposes an approach to generate test cases from BPMN models, for automated testing of Web applications implemented with the support of BPM suites. The work is primarily focused on functional testing and has the following objectives: (i) identify execution paths from the flow analysis in the BPMN model and (ii) generate the initial code of test scripts to be run on a given Web application...
In this paper, after a brief introduction on the developed plug-and-play (PnP) process monitoring and control architecture, a decentralized plug-and-play (PnP) process monitoring system for large-scale industrial processes is studied. And then, aiming at lower online computational load and more flexible industrial implementation, a decentralized adaptive configuration technique is further developed...
Although process monitoring is important for maintaining safety and product quality, it is difficult to understand process characteristics particularly when they are changing. Since the correlation among variables changes due to changes in process characteristics, process data visualization based on the correlation among variables helps process characteristic understanding. In the present work, a...
Increasing the safety of a navigation lock, by creating a modern and efficient communication between the human operator and the machine, for a prompt and accurate information offered to the operator, about the status of the equipment it serves, it is a requirement of today navigation worldwide. This paper aims to describe the implementation of a modern and efficient centralized tracking equipment...
We describe a cloud-based architecture for monitoring large numbers of industrial automation devices. We are interested in massive parallel monitoring of software components controlling critical automation facilities such as factories, mines or oil rigs. Monitoring focuses on post-deployment verification, aiming at discovering specification violations indicating for example bugs or incompatibilities...
Predictive process monitoring emerged as a technique to anticipate the outcome of a running instance of a business process. To this end, it first constructs a forecast model based on an encoding of traces of past process executions that are labelled with the prediction target. This model is then used to predict the outcome of a running process instance. However, existing approaches neglect that real-world...
This work presents a solution for radiation hardness grading procedure using compact X-ray facility built in probe station, with automated measurement system based on NI PXI platform. The radiation grading procedure can be integrated as additional stage to provide rad-hard option of conventional process. Using the radiation grading procedure as a stage of IC fabrication process, the total ionizing...
This paper addresses requirements from future automotive electronics system concept/design to computing technology or platform filling processing characteristics which will be used in applications of automated driving generation. We cannot completely predict future trends of functionality or application, so it is important to have flexible and scalable computing platform for that generation. The platform...
Inside of any organization, the acquisition process of product or service is extremely important and if not done properly can cause uncountable damage. In this way, the software acquisition isn't different and can cause uncountable problems too, like delays in existing contracts or even the dependence on the company contracted to code the product. Thus, the objective of this work is provide a software...

Governance of Information Technology (IT) aims to direct and control the current and future use of IT for the benefit of an organization, in order to guide the management of IT organizational resources globally through means and resources such as: access policy, risk management, human resource management, information access, transfer, storage and processing technologies and processes. This article...
The timber's drying process is a mandatory operation before any action of the wood processing. In the recent years, the fundamental research in the field of timber's drying has made progress, the physical laws regarding the removal of the water from the wood through different procedures (convection, vacuum, microwave etc.) being elucidated. The using of the calculus techniques allows the accurate...
Good management of public money, transparency and accountability are pillars of best practices of public governance. However, reliable, timely and timely information for constant decision-making is essential. Nevertheless, the information provided is recurrently generic, dense and technical. In this sense, the study aimed highlight the problem of redundant information to which municipalities are subject,...
This paper presents the results of a bibliometric study about the evolution of research on Continuous Auditing. This study has as main motivation to find reasons for the very slow evolvement of research on this topic. In addition, Continuous Auditing is one of the features of the emerging concept of Continuous Assurance. Thus, considering that Continuous Assurance represents numerous advantages for...
The present proposal is based on the use of mobile applications to stimulate social participation to strengthen the Sistema Único de Saúde (SUS) of Brazil and the inclusion of the citizen as protagonist to monitor public health policies. The general objective is to present a technological platform for mobile devices that enables citizens to participate and record information about health facilities,...
The conventional multivariate statistical process control (MSPC) methods may not be sensitive to the detection of incipient changes since they in general quantify the distance between the new sample and the modeling samples without checking the changes of data distribution. In the present works, a method with dissimilarity analysis and quality-relevant subspace decomposition based on process monitoring...
Multi-phase is one of the characteristics of the batch process. In this paper, Density Peaks Clustering (DPC) algorithm is applied to identify the different sub-phases and transition phase of batch processes. First, the three-dimensional training data is unfolded into K time-slice two-dimensional matrices. Then, the DPC algorithm is used to find out the cluster centers and divide the process into...
The multivariate statistical process monitoring methods represented by the partial least squares method are widely used in quality control and fault diagnosis. However, the existing partial least squares method has certain shortcomings in application. In order to enhance the nonlinear processing ability of system monitoring, a locally linear embedding enhanced partial least squares (LLEEPLS) model...
