As the inspection requirement of engineering machinery cab is analyzed, the intelligent detection system for cab based on compactRIO(CRIO) is designed, which is combined with NI LabVIEW and embedded modules of CRIO. In engineering Machinery cab, the designed system can realize intelligent supervisory and networking management of testing data for electrical system. And then, a set of complete and systematic...
This paper focuses on performance testing of electronic noses for environmental odour monitoring in terms of their capability of correctly classifying odours at low odour concentrations. The studied case concerns the realization of an electronic nose network for the continuous monitoring of odour emissions from a crude oil extraction and separation plant. The novelty of the work consists in the fact...
This paper describes the proposed system, which is able to monitor, record and give indicator about air quality information especially the CO values in the environment. The system is designed to work real time using web-based and android applications. A portable gas detector was developed using micro controller. In order to detect the CO value, TGS2600 is used; here an additional function is added...
The practice of continuous deployment enables product teams to release content to end users within hours or days, rather than months or years. These faster deployment cycles, along with rich product instrumentation, allows product teams to capture and analyze feature usage measurements. Product teams define a hypothesis and a set of metrics to assess how a code or feature change will impact the user...
Nucleic acid amplification is a powerful technique for rapid pathogen detection due to its high analytical sensitivity, specificity and speed, but the complexity of multistep assay preparation confines their use to laboratories maintained by medical scientists and specialized equipment. Using a droplet magnetofluidic approach to miniaturization for nucleic acid testing at the point of care, we report...
This paper describes a phase switching algorithm for Interpolating Digital-to-Analog Converter (DAC) based Arbitrary Waveform Generators (AWG). This was possible by using the standard phase switching algorithm with the addition of simple phase offset and systematic phase difference adjustment; this was discovered by experimenting with suppression of the intermodulation distortion (IMD) components...
Most techniques to detect program errors, such as testing, code reviews, and static program analysis, do not fully verify all possible executions of a program. They leave executions unverified when they do not check certain properties, fail to verify properties, or check properties under certain unsound assumptions such as the absence of arithmetic overflow. In this paper, we present a technique to...
Programs written in unsafe languages like C and C++ often suffer from errors like buffer overflows, dangling pointers, and memory leaks. Dynamic analysis tools like Valgrind can detect these errors, but their overhead — primarily due to the cost of instrumenting every memory read and write — makes them too heavyweight for use in deployed applications and makes testing with them painfully slow. The...
In recent years, researchers have intensively investigated various topics in test prioritization, which aims to re-order tests to increase the rate of fault detection during regression testing. While the main research focus in test prioritization is on proposing novel prioritization techniques and evaluating on more and larger subject systems, little effort has been put on investigating the threats...
Although white-box regression test prioritization has been well-studied, the more recently introduced black-box prioritization approaches have neither been compared against each other nor against more well-established white-box techniques. We present a comprehensive experimental comparison of several test prioritization techniques, including well-established white-box strategies and more recently...
Software defect localization is an important step in the process of fixing defects and is a necessary means to improve software quality. In the process of fixing defects, it is also the most time-consuming and laborious task to accurately locate the files where the defects should be fixed. In order to clarify the research progress in the field of defect localization, we introduce the key technologies...
This papers deals with an advanced and effective approach for testing system, by utilizing the hardware-in-the-loop (HIL) with the vision based machine learning technique to make end to end automation in the feature diagnosis and validation of automotive instrument clusters. Recently, numerous HIL systems are in practice for simulating the vehicle networks in real time, by providing necessary signals...
The present study used fuzzy triangulation number to analyze self-assessment (SA) of 86 nonnative novice and experienced Iranian English language teachers. Fuzzy triangulation number was used to provide a score for each item of a 7 scales SA questionnaire (SAQ). These fuzzy scores were then compared to the teachers' obtained scores in FCE test. The teachers' scores obtained from the listening and...
This paper presents a new system for singing melody transcription from polyphonic songs. Instead of operating solely on polyphonic audio of each song to be processed (as most existing systems do), our system takes as inputs additionally multiple monophonic recordings of people singing the song. To transcribe the singing melody in a song, our system first tracks the singing pitch from polyphonic audio...
In this paper we assess and evaluate the quality of t-way combinatorial test-suites using three different test-suite quality assessment methods. As t-way combinatorial test-suites reduce the input space of a program under test, we investigate how an increasing t affects the quality of the test-suite. There are some limitations of existing test-suite quality assessment methods e.g. the number of mutants...
Data flow testing (DFT) has been shown to be an effective testing strategy. DFT features a high fault detection rate while avoiding the intense scalability problems to achieve full path coverage. In this paper we propose to apply data flow testing for SystemC virtual prototypes (VPs). Our contribution is twofold: First, we develop a set of SystemC specific coverage criteria for data flow testing....
Mutation testing is widely considered as a high-end test criterion due to the vast number of mutants it generates. Although many efforts have been made to reduce the computational cost of mutation testing, its scalability issue remains in practice. In this paper, we introduce a novel method to speed up mutation testing based on state infection information. In addition to filtering out uninfected test...
The increasing demand for clean energy and sustainable living have been promising for Photovoltaic (PV) systems. However, in urban environments, uniform solar insolation is not guaranteed. Thus, conventional Maximum Power Point Tracking (MPPT) techniques severely fail at Partially Shaded Conditions (PSC). In response, a new hybrid technique is being proposed using Adaptive Network-Fuzzy Inference...
The testing process of a low noise RF pre-amp in most of the semiconductor fabrication industries is either fully manual or employs expensive test systems. An efficient and low cost automated testing system is elucidated in this paper. The design and development of the automated RF test system is realized. The whole process involves the development of an Automated Test System (ATE) and a software...
Active ECUs (Electronic Control Unit) in a hybrid car while it is charging leads to inefficient power usage and reduction in ECU lifetime. To solve this issue, AUTOSAR has suggested PN (partial networking). As per the AUTOSAR specification, ECUs which are not required to be kept active during battery charging must be shutdown. This project's aim is to analyze the robustness of the design suggested...
