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...
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...
Following the Service-Oriented Architecture, a large number of diversified Cloud services are exposed as Web APIs (Application Program Interface), which serve as the contracts between the service providers and service consumers. Due to their massive and broad applications, any flaw in the cloud APIs may lead to serious consequences. API testing is thus necessary to ensure the availability, reliability,...
This paper is using artificial neural network (ANN) to predict oxygen content in the water for the fish farm, so that decrease times of starts of oxygen suppliers. In Southern Taiwan, aquaculture is one of major economic industries. Especially, the important issue is how to effectively monitor the oxygen content in the water, so that the fish will not die and start the oxygen suppliers for the minimum...
Wind-flow around a long-span bridge, as a bluff body, will generate an aerodynamic force that interacts with the flow, causing vibration to the bridge deck. This phenomenon can lead to structural fatigue or worst, the bridge collapse. A continuous and comprehensive measurement system is needed for early detection and maintenance reference of a long-span bridge. Another benefit this system is aiming...
High quality requirements are set for automated production systems (aPS) as malfunctions can harm humans or cause severe financial loss. These malfunctions can be caused by faults in the control software of the aPS or its inability to correctly identify and handle unintended situations and errors in the technical process or hardware behavior. To achieve more dependable control software, software testing...
We present single event transient (SET) and total ionizing dose (TID) data for the single channel voltage supervisor fabricated in a 0.35μm triple-well, mixed-signal CMOS process.
Total dose test results are presented for the Maxim 1257/1258 multi-channel ADC/DAC, and the Linear Technology LTC2378-20 low power SAR ADC. The paper discusses radiation testing challenges of complex mixed signal circuits.
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...
Developing a virtualized network service does not only involve the implementation and configuration of the network functions it is composed of but also its integration and test with management solutions that will control the service in its production environment. These integration tasks require testbeds that offer the needed network function virtualization infrastructure (NFVI), like OpenStack, introducing...
