Music is filled with mathematical relations. When creating music, the composer must keep in mind the rhythm, the notes, and how well they ring with each other. Our aim was to design an application that teaches these relationships and allows users to compose their own songs using numbers. Our work follows the design science research method, and we have co-designed the application together with elementary...
There are many research works on automated GUI traversal-based test case generation techniques for Android application. However, the effect of different factors used in a GUI traversal algorithm has not been systematically explored. In this work, we report a controlled experiment on 33 real-world applications to expose their real failures to systematically study three major factors that are commonly...
This research has been carried out to find an intelligent system to generate chords for melodies which has been composed without considering chords initially. In western music, melodies are composed alongside with chords which specifies the rules for composing. Even though, the concept of chord is not practised in Hindustan music, modern musicians are now adapting the chords and use western instruments...
Energy consumption is one of the most important aspects of mobile apps. During energy testing, it is important for developers to understand not only the energy consumption rate of an app, but also why energy is consumed. However, existing energy testing tools are more concerned about the accuracy of energy estimation, while typically not providing explanations on why and how exactly energy has been...
This article reports study results in which participants (n=145) responded to a variety of negative messages in a variety of message channels, visual, textual, and verbal. Participants participated in A-B testing of distinct message strategies and then identified communication values that seemed most important in distinct message contexts. Results showed very clear differences between two broad classes...
The World Wide Web network, with its ubiquitous nature, a multitude of functionalities, and a broad range of benefits seems to require proper care and maintenance in support of its continued development. This responsibility lies largely in the hands of web designers and those involved in the administration of individual pages as fundamental units of the entire virtual reality of the WWW system. It...
Recent revisions of IEC 60034-27-3 and API 541 now include recommended acceptance criteria for dissipation factor (DF, or tangent delta) measurements and offline partial discharge (PD) analysis, which are common factory acceptance tests of sacrificial coil samples of new medium voltage stator windings. IEC 60034-27-3 recommends acceptance limits for DF & tip-up and API 541 recommends 100 pC for...
This paper provides a description of Absence of Voltage Testers (AVTs), their use, listing requirements (as defined in UL 1436), and application considerations. A discussion of how AVTs can be used to support NPFA 70E work practices, as well as advantages and limitations are also addressed.
This article describes a method for the long-term testing of storage batteries and high-capacity ion sources, implemented using National Instruments technologies. A test stand was developed using DAQ NI USB-6001. A brief description of the program implemented in NI LabVIEW is given. The part of the program code is opened — the block diagram of correction of temperature coefficients. The interface...
The paper describes automated system for MIL-STD-1553 integrated circuits functional and parametric control based on National Instruments hardware and software. Automated measuring system block-scheme is presented. The paper discusses the process of ICs testing and software and hardware description.
Fuzzing is attractive for finding vulnerabilities in binary programs. However, when the application's input space is huge, fuzzing cannot deal with it well. For discovering vulnerabilities more effective, researchers came up concolic testing, and there are much researches on it recently. A common limitation of concolic systems designed to create inputs is that they often concentrate on path-coverage...
This paper presents a set of low-cost desktop IC test systems developed for engineering education. The set is implemented using the National Instrument (NI) Educational Laboratory Virtual Instrumentation Suite (ELVIS) and custom-made load boards. The software is based on the NI LabVIEW development environment. The set has been developed and employed for teaching electronic testing, instrumentation...
Recent advances bring new challenges to different aspects of power systems. These challenges necessitate new philosophy and paradigm shifts in power system protection, control, and operation. This paper describes a dynamic state estimation-based centralized protection scheme (DSEBCPS) that provides a new paradigm for a resilient protection system for the power system of the future. The proposed system...
We demonstrate a desktop platform which has the ability of modeling ReRAM TiO2 samples in a highly automated manner. The system consists of a bespoke RRAM characterization instrument that hosts packaged RRAM devices and is operated via a PC. The system's python-based software includes a module that automatically applies strategically chosen sequences of pulses to a test device and then extracts the...
Partial Discharge (PD) detection and analysis is playing an increasingly important role in the validation and quality control of insulation systems for ac stator windings, [1]. The availability of advanced PD instruments provided by separation and defect identification facilities, has opened interesting perspectives in insulation system characterization, [2, 3]. However, constrains based on existing...
Describes the universal approach to the intellectual automated system development of digital signal processing for acoustic testing devices with free vibrations method and the usage of artificial neural networks. The system solves the problem of defects recognition and classification, and enhances performance testing in comparison with traditional instruments.
We live in a world of Energy. We use it and, following the laws of Thermodynamics, give up a portion of that as inevitable toll for its conversion for our purposes. There are the non-conventional sources around us. Utilization of these energies will help to reduce harmful pollution caused by the oil and coal technologies and save money for the social developments. Beside the previously considered...
Digital microfluidic biochip (DMFB) is an attractive platform for immunoassays, point-of-care clinical diagnostics, DNA sequencing, and other laboratory procedures in laboratory experiments due to its flexible application and low fabrication cost and further for the development of instruments. As being applied for these safe-critical applications, on-line testing methods are required to ensure robust...
This paper aims to present a new method for automated testing of industrial equipment, used primarily in the automotive field. The underlying concept of this work consists in developing an application to test the equipment (DUT — device under test) that automated tests need to be performed on, from the point of view of the hardware system, and in terms of the software loaded on such a device. The...
As many automated test input generation tools for Android need to instrument the system or the app, they cannot be used in some scenarios such as compatibility testing and malware analysis. We introduce DroidBot, a lightweight UI-guided test input generator, which is able to interact with an Android app on almost any device without instrumentation. The key technique behind DroidBot is that it can...
