This paper presents a in situ on-chip micro tensile fracture strength tester, which is based on a thermal actuated test platform. In this test platform, tensile fracture strength could be extracted and process could be evaluated, there are two samples with same layout but fabricated under different process conditions were evaluated through this test platform and the results showed that this test platform...
Available sensing measurements in modern industrial process include two significant characteristics: distribution and autocorrelation. Different types of sensing measurements exhibit different characteristics. Moreover, different feature extraction methods are suitable for data with corresponding characteristics. This paper proposes a novel dual-step subspace partition method in order to establish...
The Kansas City National Security Campus (KCNSC) collects a large amount of test data used to accept high value and high rigor product. Data has been used historically to support root cause analysis when anomalies are detected in down-stream processes (bottom portion of Fig. 1). The opportunity to use the data for predictive failure analysis however, had never been exploited (top portion of Fig. 1)...
Deployed test and health monitoring systems must actually manage two tasks: (1) the testing and monitoring the device under test, and (2) the testing and monitoring the test system itself. The ability to isolate and identify faults is crucial to deployed test and health monitoring systems. Understanding failure mechanisms provides invaluable insight regarding whether the device under test is, in fact,...
A novel approach of a test environment for embedded networking nodes has been conceptualized and implemented. Its basis is the use of virtual nodes in a PC environment, where each node executes the original embedded code. Different nodes run in parallel, connected via so-called virtual channels. The environment allows to modifying the behavior of the virtual channels as well as the overall topology...
In the article the features of wireless smart biosensor for sensor networks in ecological monitoring are considered. The developed wireless smart sensors manufactured on certified contract manufacture, is described. The results of wireless sensors testing are given.
Corrosion of metal alloys is very common in the industrial field, and failure to monitor the seriousness of corrosion can cause serious consequences. Compared with other Non-Destructive Testing methods, the method of ultrasonic surface wave testing has a lot of advantages including portability, efficiency, and un-contamination etc. This makes it a very promising method to evaluate or monitor chemical...
On the example of operations for manufacturing the “Axis” detail, the effectiveness of statistical control of the technological production process for the “Nalchik plant of highvoltage equipment” is demonstrated. Specific recommendations on the effective quality assurance of parts are given.
Automated Test Systems (ATSs) can join the Internet of Things (IoT) at multiple layers and benefit both the overall IoT concept as well as advance the goals of ATSs. Logistics and sustainment are traditionally brought into the IoT conversation through asset tracking, transportation, and Health and Usage Monitoring Systems (HUMS). However the IoT has additional aspects that can be related to logistics...
Phasor Measurement Units have become more and more interesting for monitoring applications in distribution grids. For a large exploitation in medium and low voltage networks, however, a limited cost is required. Such specification, however, should not impact excessively the accuracy requirements, as it is expected that automatic control functionalities will run based on state estimation algorithms,...
With the rapid development of Internet technologies such as cloud computing and big data, the scales of distributed information systems in big companies have grown to enormous sizes. Automatic detection and diagnosis of system faults in the large-scale information systems is complicated and important in both practice and research. In this paper, we propose a Graph-based Fault Diagnosis approach in...
In order to effectively develop AAL solutions, it is crucial to analyse user requirements. The determination of actual user needs can make the difference between a nice to have and a real innovation. Integrating the target group successfully means being able to detect requirements and errors as well as needs, fears and barriers and utilize creative potential. The main advantage of such testing is...
The design of new device for electromagnetic compatibility testing — environmental shielded TEM-chamber — is considered. Diagnostic algorithms and functional structure decomposition of the chamber are presented. Tasks for a monitoring service of the chamber are indicated. The possibility of the diagnostic service implementation within a real-time operating system is considered for the chamber status...
This article reports on our experiences in applying formal methods to verify the security mechanisms of Android. We have developed a comprehensive formal specification of Android's permission model, which has been used to state and prove properties that establish expected behavior of the procedures that enforce the defined access control policy. We are also interested in providing guarantees concerning...
The school shuttle system commonly uses the vehicle to facilitate students to go and go home from school. However, there needs to be a development in terms of monitoring the students. In this paper explains the development of school shuttle system with IoT concept to apply Smart School application. The system will be designed uses a reader that will identify the identity card of students using Bluetooth...
The results of Stiftung Warentest, ÖKO-TEST and the official control laboratories are poorly comparable because of their different objects, even if there are some overlaps. Given the example of cosmetic sunscreen products, which had been tested by all 3 institutions over several years, the differences in testing and evaluation are presented. We show that also the testings of the single institutions...
In this paper, we address the problem of fault detection (FD) of chemical processes using improved generalized likelihood ratio test. The improved GLRT is the method that combines the advantages of the exponentially weighted moving average (EWMA) filter with those of the GLRT method. The idea behind the developed EWMA-GLRT is to compute a new GLRT statistic that integrates current and previous data...
The number of deaths due to the motor vehicle accidents has increased drastically during the last few years. It is estimated that nearly 40–50 % of the accidents are due to the distractions of the driver. One of the methods to assess driver distraction is using head pose estimation. The unavailability of a standard driving database hampers the study and testing of driver distraction algorithms. In...
The significant decrease in agricultural land and the rapid development of hydroponic system technology such as Nutrient Film Technique (NFT), have brought huge challenge to farmers. This hydroponic system requires special attention to several parameters such as the water temperature, water level, acidity (pH), and the concentration of the nutrient (EC/PPM). We first monitor and collect information...
System-on-a-Chip (Soc) design has become more complex, because many functional components or IPs (Intellectual Property) will be integrated within a chip. The test of integration is “how to verify on-chip communication properties”. Since conventional simulation-based bus protocol monitors can validate whether bus signals obey bus protocol or not, but they often lack of efficient debugging techniques...
