This article deals with the technical testing of device for integrated evaluation of the antioxidant activity of foods. Results of technical testing are given. The major attention is paid to testing of hardware implementation of device.
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.
This paper presents two different implementations for recognition of handwritten numerals using a high performance autoencoder and Principal Component Analysis (PCA) by making use of neural networks. Different from other approaches, the non-linear mapping capability of neural networks is used extensively here. The implementation involves the deployment of a neural network, and the use of an auto encoder...
This experience paper presents how a globally distributed software engineering team was able to deliver usable software at the end of each takt, why this was important, and the benefits derived. We also describe the approach taken, the challenges faced and the steps to overcome them.
Formal approaches to software development have traditionally aimed at guaranteeing software correctness, through the use of notations, analysis mechanisms and other elements founded on solid mathematical grounds. Since the seminal works of Hoare, Floyd and others, formal methods have used logical notations to capture intended software behavior, and proposed techniques for reasoning about software...
The effects of temperature and tensile velocity on the mechanical properties and mechanics of Au/Cu/Au/Cu nanofilms under tensile testing are studied using molecular dynamics simulations. The simulation results show that at the initial tensile deformation, dislocations nucleate at layer interfaces, propagate along close-packed plane {111} toward the interior of the film, and are then terminated by...
Preschoolers as digital native cannot avoid gadgets. Game applications are more accessible to them. People believe that games have a negative impact such as bad character and violence. Nevertheless, the game can be developed into a fun tool. This research aimed to design a game prototype boosting cognitive abilities for preschoolers. Prototyping and testing the game system were the method. A preschoolers'...
Region merging is one of important steps in an image segmentation system, which can be used for partitioning the objects in images. This paper presents a region merging method based on hue angles (RMHA). The RMHA employs the architecture of the Improved Quad-tree Method (IQM) [7]. We propose the homogeneity testing based on hue angles (HTHA) as the core of the IQM. The HTHA merges two adjacent regions...
Mobile app testing is challenging since each test needs to be executed in a variety of operating contexts including heterogeneous devices, various wireless networks, and different locations. Crowdsourcing enables a mobile app testing to be distributed as a crowdsourced task to leverage the crowd in a community. However, a high test quality and expected test context coverage are difficult to achieve...
As software systems become more complex, the number of test cases required for effective testing becomes intractable. Cache misses have been identified as a major factor that affects software execution time. In our current work we target the instruction locality problem in the context of testing.
In this paper we present a case study of applying fitness dimensions in API design assessment. We argue that API assessment is company specific and should take into consideration various stakeholders in the API ecosystem. We identified new fitness dimensions and introduced the notion of design considerations for fitness dimensions such as priorities, tradeoffs, and technical versus cognitive classification.
Testing of mobile applications becomes more importantas the usage of smartphones increases. Many studiesuse Monkey, a basic testing tool provided by Android. WithMonkey, however, it is hard to replay the behavior of actualusers. In this work, we present a mobile app testing methodthat automatically records and replays user event logs on thesmartphone. From replay testing experiments, we have shownthat...
Selenium IDE is a glorious state-of-the-art integrated development environment for recording and playing Selenium test cases for web testing. However, it does not support automatically locating unnamed popup windows and inner frames, which impedes creating a sequence of test commands across different windows and inner frames. In this work, we extend Selenium IDE and propose a technique to dealing...
Fully assessing the robustness of a software application in-house is infeasible, especially considering the huge variety of hardly predictable stimuli, environments, and configurations that applications must handle in the field. For this reason, modern testing and analysis techniques can often process data extracted from the field, such as crash reports and profile data, or can even be executed directly...
Background: Test quality is a prerequisite for achieving production system quality. While the concept of quality is multidimensional, most of the effort in testing context hasbeen channelled towards measuring test effectiveness. Objective: While effectiveness of tests is certainly important, we aim to identify a core list of testing principles that also address other quality facets of testing, and...
Agile software development principles enable companies to successfully and quickly deliver software by meeting their customers' expectations while focusing on high quality. Many companies working with pure software systems have adopted these principles, but implementing them in companies dealing with non-pure software products is challenging. We identified a set of goals and practices to support large-scale...
Abstract test case prioritization (ATCP) aims at ordering abstract test case in order to increase the speed at which faults are detected, potentially increasing the fault detection rate. This paper empirically examines possible ATCP techniques, according to the following four categories: non-information-guided prioritization (NIGP), interaction coverage based prioritization (ICBP), input-model mutation...
Using topic modeling, we analyse the titles and abstracts of nearly 10,000 papers from 20 years published in 11 top-ranked Software Engineering(SE) conferences between 1993 to 2013. Seven topics are identified as the dominant themes in modern software engineering. We show that these topics are not static, rather, some of them are becoming decidedly less prominent over time (modeling) while others...
Handwritten text in any language is believed to convey a great deal of information about writers' personality and identity. Handwritten documents are frequently used as evidences in forensic tasks. Handwriting skills is learnt and developed from the early schooling stages. Research interest in behavioral biometrics was the main driving force behind the growth in research into Writer Identification...
