5G does not only aim at higher capacity and lower latency than current 4G in mobile broadband networks, but also to increase the level of programmability, control and flexibility to meet the requirements from innovative use cases such as IoT, smart manufacturing, and immersive media. However, several difficulties still need to be overcome for a better technological adoption. To reduce the time-to-market...
The purpose of this research is proposing a theory to verify the influence of virtual props trading sites to game loyalty of players. The objects of sampling aims at users who are actually engaged in online games props trading sites. A survey of 459 game players in Taiwan was conducted; research results were generated through the use of descriptive analysis, reliability analysis, correlation analysis,...
Based on the analysis of current conditions and shortages of the configuration files management in smart substation, the problems existing in current conditions are proposed, such as: ICD test technology, SCD test technology, SCD difference comparison technology. In order to meet the demand of the large scale smart substation construction, a solution of building the smart substation configuration...
Given today's fast growing automotive semiconductor industry, this tutorial will discuss the implications of automotive test, reliability and functional safety requirements on all aspects of the SOC lifecycle: design, silicon bring-up, volume production, and particularly in-system functional safety. Today's automotive safety critical chips need multiple insystem self-test modes, such as power-on self-test...
The experience of the department of the economic theory on the development and usage of technology for electronic testing and accompaniment of business games in the teaching of economic theory for students of technical stream is described.
In the technical support division of a large enterprise software provider, customers' technical incidents, problems, and change requests are processed as tickets. Each ticket is assigned to a support engineer for processing. Due to the limited expertise of individuals, resolving a ticket may involve routing the ticket among multiple groups of engineers. Each routing step costs time and resources....
Globalization allows many industries and enterprises to corporate and communicate with each other to provide services. In the era of knowledge management semantic web and related technology plays a major role. Ontology being the basic unit of semantic web realization will contain knowledge which is sharable between different domains. Ontology matching techniques are vital in querying and finding the...
Essentially, opinion reviews are a valuable and trustworthy source of information for the readers. However, regarding the business purposes, a huge number of deceptive opinions are intentionally posted on the Web. In order to keep opinion reviews as a precious and trusted resource, we propose a method which focuses on detecting positive and negative deceptive opinions. In this paper, we explore the...
Automation of software testing is a complex problem with multiple facets to be handled in sync to be viable. In this work we propose two novel concepts; model dressing for automated exploratory testing. Model dressing maps an application under test to a model created for the domain of the application. In its simplest form, the domain model defines the business tasks as well as the user actions that...
Technical Debt (TD) refers to the long-term consequences of shortcuts taken during different phases of software development life cycle. Lack of attention to monitoring and managing testing and development debt can contribute to unexpectedly large cost overruns and severe quality issues in software development projects. This paper describes a case study conducted with an industry partner to explore...
Credit scoring is an important process in every financial institution and bank. Its high accuracy in classifying customers helps decrease the credit risk and increase reliability and profit. In this paper, we propose a binary classification approach that can classify customers who apply for loans. A statistical technique called Stepwise Regression (SR) is used as a pre-process to select important...
The speed of development of the IT industry as well as the computational power which are increasing exponentially, create great competitiveness in the process of development but also in the launching of software products on the market. Automated testing comes to help with these challenges by trying to increase the speed of development by offering fast feedback and trustworthy quality by means of repeated...
Software startups can be subject to extreme money and time constraints while hoping for delivering reliable software. In a harsh startup environment, software may face quality downgrade either by improper process management or incapable human resources. Among the many, security is a fragile software quality characteristic responsible for severe negative consequences such as jeopardizing a startup's...
Previous work has demonstrated that property-based testing (PBT) is a flexible random testing technique that facilitates the generation of complex form data. For example, it has been shown that PBT can be applied to web-service applications that require various inputs for web-forms. We want to exploit this data generation feature of PBT and combine it with an external test-case generator that can...
Data-intensive systems in e-governance collect and process data to ensure conformance to a set of business rules. Testers meticulously verify data in test databases, extracted from different steps of a live production stream , for correct application of business rules. We simplify the process by allowing testers to model a test domain on a relational database and automatically generate test cases...
Web service composition involves a collection of web services; the interaction among the participating services makes the testing of the web service composition significantly complicated. In this paper, we present an approach of test case generation for Business Process Execution Language (BPEL) based web service composition using Colored Petri Net (CPN) which provides a strong formal background for...
In the current paper we describe how Watson Experience Manager (WEM), an industrial Question Answering (QA) tool developed by IBM, has been used in an educational context at the National Technical University of Athens (NTUA). During the postgraduate course on Data Science, three student teams experimented with WEM's QA capabilities on three different topics, namely, Nutrition, Autism and New York...
To ensure the delivery of high quality and robust service-oriented applications, testing of web services composition has received much attention. These services have become more and more complex, where they have to cope with strict requirements of business processes and their dynamic evolution, and interactions among different companies. In this context, the analysis and testing of such services demands...
The creation of a suite of unit testing is preceded by the selection of which components (code units) should be tested. This selection is a significant challenge, usually made based on the team member's experience or guided by defect prediction or fault localization models. We modeled the selection of components for unit testing with limited resources as a multi-objective problem, addressing two different...
Web applications are nowadays being used to support enterprise-level business operations and usually rely on back-end databases to deliver service to clients. Research and industry reports indicate the huge impact the quality of the data can have on businesses, especially when applications are not prepared for handling low quality data. In fact, even in widely tested and used applications, the presence...
