The paper concerns the detection of fall events based on human silhouette shape variations. The detection of fall events is addressed from the statistical point of view as an anomaly detection problem. Specifically, the paper investigates the multivariate exponentially weighted moving average (MEWMA) control chart to detect fall events. Towards this end, a set of ratios for five partial occupancy...
With growing complexity of premium cars, the end-of-line test systems also increase in complexity. The test systems have to provide more and more functionality like flashing of electronic control units (ECUs) and sensor calibration. Current end-of-line test systems evolved to complex networked IT-systems, which consist of various components and subsystems from different suppliers. Automotive production...
The emergence of the Industrial Internet results in an increasing number of complicated temporal interdependencies between automation systems and the processes to be controlled. There is a need for verification methods that scale better than formal verification methods and which are more exact than testing. Simulation-based runtime verification is proposed as such a method, and an application of Metric...
Third-party measurements of cloud availability are needed as a checkpoint of cloud providers' quality statements, and ICMP has been proposed to carry on such measurements. Simple ICMP-based measurement schemes, however, provide a poor discrimination between false outages and true cloud outages, unless the cloud outage probability is quite higher than the packet loss rate incurred by probing packets...
Performance testing is an important process in the embedded software development. It can detect bugs, help improve software quality and test the system reliability. The objective of this paper is to propose a performance testing method for embedded software platforms. A case study to evaluate the applicability of the proposed method is discussed. Performance tests are performed on three different...
For non-destructive testing (NDT) to be applicable in mechanical equipment, it is mandatory that NDT is highly flexible, accurate and robust. At present there have been several methods based on acoustic, optical and electromagnetic information to detect the cracks of the mechanical equipment. As a new technology, the fusion of testing information harnesses the advantages of various NDT instruments,...
Any adaptive traffic control system applied for an entire network must be flexible, in order to adjust the signalling times for each junction according with real traffic data, according to a macroscopic vision. Also, it must be network synchronized, in order for each signalling time modification to be correlated with the other junctions in the network. The system must also be able to properly respond...
In this paper, we propose reversed taint analysis to dig out the root cause of the vulnerability leading to crash. In order to increase the efficiency, we propose that during the analysis process, we should only taint the EIP register when the crash happens and then trace back to analyze the data and operations, until we find out the influential inputs that can be controlled by the users. In addition,...
Self-healing is an interesting topic in SON (Self- Organizing Networks). In this paper, we investigate cell outage detection problem, and propose an improved TCM (Transductive confidence machines) based automatic cell outage detection algorithm. By incorporating a hypothesis test with the Neyman-Pearson criterion to improve the detection accuracy, the improved TCM can effectively detect cell outage...
The rapid development of mobile telecommunication industry has brought great convenience to people's lives, and even progressively have changed our way of life. With the continuous improvement regarding coverage area, internet speed etc. of requirements, there are more and more mobile base stations, and the issue concerning the electromagnetic radiation of mobile base station is also of very high...
This paper describes the concept of the portable system for monitoring thermal exposure of firemen and other rescues. The system measures, archives and analyses actual external and internal temperatures affecting the monitored person and gives him a warning in case of dangerously increased values. Described is the construction and electrical components of the device, some important tests done in various...
In this paper, we propose a novel intrusion detection technique using a deep neural network (DNN). In the proposed technique, in-vehicle network packets exchanged between electronic control units (ECU) are trained to extract low- dimensional features and used for discriminating normal and hacking packets. The features perform in high efficient and low complexity because they are generated directly...
In recent years, there has been a shift in the process of performing electromagnetic interference (EMI) and electromagnetic compatibility (EMC) testing from a manual approach to a software-driven, automated approach. Generally speaking, this automation has provided numerous benefits to both those responsible for performing testing, as well as for those whose product is under test. This paper will...
Recent advances for the treatment of a cerebral aneurysm include a neurovascular flow diverter which can cover the entire length of the aneurysm inside the vessel. The flow diverter reduces blood flow that enters the aneurysmal sac without any adverse effects on the normal directional flow in the vessel. However, existing neurovascular flow diverters show a lengthy curing rate of the sac, which requires...
Ultrafiltration is applied to remove particles, colloids and large macromolecules from ultrapure water for semiconductor device manufacturing. Early detection of leaks, pinholes and fiber breaks in membrane modules is an essential prerequisite for this ultimate task and a first step for defect free manufacturing. Particle monitoring alone is not sufficient. Periodic pressure-hold testing enables much...
Remote software usability testing has been studied for over two decades. Yet, many of the existing testing methods are not ideal for field testing in challenging environments typical to military and emergency operations and contexts. In this paper we introduce a model and a messaging framework that allow remote usability tests to be run easily in the real work context of the users. We also introduce...
The paper describes the approaches to the solution of some problems in existing systems of acoustic emission monitoring. Provides the substantiation of the relevance of such problems and possible ways of their solution. The principles underlying the proposed solutions implements in the form of research acoustic emission system.
In the state of the art development of chip manufacturing (FinFet technology for example) both optical inspection and inline electrical test are deployed to monitor and facilitate the process development. While optical inspection provides critical process evaluation at the sector inline electrical test (ILT) at M1 provides the information of process impact on the electrical signal, which ultimately...
Cardiotocography (CTG) is a monitoring technique that is used routinely during pregnancy and labor to assess fetal well-being. CTG consists of two signals which are fetal heart rate (FHR) and uterine contraction (UC). Twenty-one features representing the characteristic of FHR have been used in this work. The features are obtained from a large dataset consisting of 2126 records in UCI Machine Learning...
Implantable medical devices are recommended by physicians to sustain life while improving the overall quality of life of the patients. In spite of the rigorous testing, there have been numerous failures and associated recalls which suggest that completeness of the testing is elusive. We propose a new validation framework based on formal methods for real-time closed-loop validation of medical devices...
