Counterfeit coin problem has been considered for a very long time and is a topic of great significance in Mathematics as well as in Computer Science. In this problem, out of« given coins, two or more false coins (the coins are classified as false because their weights are different when compared to a standard coin) are present which have the same appearance as the other coins. This problem belongs...
Today, in the 21st century, knowledge of science, technology and especially engineering are necessary to make informed decisions in most aspects of everyday life and the demand to fill jobs in these areas, especially engineering, is growing rapidly. Recent research indicates that a majority of college students who enter Science, technology, engineering and mathematics (STEM) majors became interested...
"Stereotype threat" is a term used by social scientists to describe the anxiety one feels when one fears that he or she will confirm a negative stereotype about his or her own group. This anxiety impairs performance and reduces motivation by introducing a self-evaluative threat. More than 300 studies have verified that people underperform when put in situations that cause stereotype threat...
As a result of classroom practice and Fulbright research in Singapore, a modular approach to employing the Engineering Design process to frame projects in secondary science curricula has been developed. It is meant to facilitate project design and implementation by teachers who have little or no background in engineering. The approach has been tried in classrooms in the United States and Singapore...
Automatic Programming Assessment (APA) has recently become a significant method in assisting educators of programming courses to automatically mark and grade students' programming as its counterpart; the typical manual tasks are prone to errors and leading to inconsistency. By default, test data generation process plays an important role to perform a dynamic testing on students' programs. In software...
Student's performance is classified into four levels, including below basic, basic, proficient, and advanced levels. The descriptions of the performance standard make students understand their learning achievement via percentile rank (PR), a norm-referenced score, and T score (I). This paper develops an adaptive student assessment system and invites elementary-school students to do a test in mathematics...
One way to provide feedback to independent novice programmers is by leveraging experienced programmers as code reviewers. To provide this feedback at a large scale, experienced programmers can author heuristic programs, or rules, that automatically determine whether a novice program should receive certain feedback. This work presents the lessons learned from designing a tool to enable rule authoring.
The method of constructing testing impacts for digital devices is proposed. The method is based on the representation device as a set of models data exchange interfaces. This approach allows to build models of input impacts as a collection of standard operations inherent to the corresponding interface.
Combinatorial Test Design, CTD, does not easily lend itself to the modeling of ordered parameter-values. Such modeling is much needed in practice, e.g. For the testing of sequences of API calls or parameterized events. We extend the CTD paradigm to address this need. We define a test as an ordered tuple of the parameter-values of the model, and introduce the concepts of ordered restrictions and ordered...
This paper presents the technology and testing platform for interoperable e-mobility, infrastructure and power grids at TU Dortmund University. That environment allows to emulate several power grid states and to analyse the behaviour of charging station and EV regarding to both electrical and ICT aspects. Using this technology platform we developed an alternative method for Residual Current Detection...
Test driven development (TDD) appears not to be immune to positive test bias effects, as we observed in several empirical studies. In these studies, developers created a significantly larger set of positive tests, but at the same time the number of defects detected with negative tests is significantly higher than those detected by positive ones. In this paper we propose the concept of TDDHQ which...
A proposed test is realized by the separation of N registered observations into k shorter series containing n observations (N = n·k), estimation and comparing the variance of the mean values of these series with an average of their variances. If the ratio of these variance estimators after normalization by the number of degrees of freedom k − 1 and N − k is greater than the critical value Fcritic(1...
The purpose of this article is to describe a new method which is proposed to be the best practice for creating a very effective password candidate lists for specified language, which could be then also used to test the security level of wireless networks protected by WPA/WPA2 PSK standards. The main principle of this technique is to create the statistical model of the new target language which could...
This workshop focuses on teaching usability at the undergraduate and master's level, and emphasizes the potential of such courses to bring the classroom and workplace together, aid student learning, and allow businesses to influence the training of the next generation of professional communicators.
Traceability between development artefacts and mainly from and to requirements plays a major role in system lifecycle, supporting activities such as system validation, change impact analysis, and regulation compliance. Many researchers have been working on this topic and have published their work throughout the editions of the Requirements Engineering Conference. This paper aims to analyse the research...
Semantic Web Services (SWS) introduce a semantic layer to the current web infrastructure, enabling the automated processing of web tasks. Different frameworks have been proposed for designing SWS, however, there has been little research in the area of testing SWS. Generating test cases for SWS is challenging due to its dynamic nature and abstract views, evaluating the test cases is equally essential...
An important aspect of traceability experiments is the ability to compare techniques. In order to assure proper comparison, it is necessary to perform statistical analysis of the dependent variables collected from technique application. Currently, there is a lack of components in TraceLab to support such analysis. The Software Verification and Validation Research Laboratory (SVVRL) and the Statistics...
There is a growing interest of the Computer Science education community for including testing concepts on introductory programming courses. Aiming at contributing to this issue, we introduce POPT, a Problem-Oriented Programming and Testing approach for Introductory Programming Courses. POPT main goal is to improve the traditional method of teaching introductory programming that concentrates mainly...
The smart cards are increasingly used in several fields with critical data that require security. We cite, as example, the medical field and payment shopping with smart card. Therefore, the hardware and software security of smart cards is one of the key elements of the security of sensitive information handled. Currently, several scientific researchers are interested in studying and enhancing the...
Aspect-Oriented Modeling (AOM) has been the subject of intense research over the last decade and aims to provide numerous benefits to modeling, such as enhanced modularization, easier evolution, higher quality as well as reduced modeling effort. However, these benefits can only be obtained at the cost of learning and applying new modeling approaches. Studying their applicability is therefore important...
