These studies focused on the Android Fragment class and the ROS framework. ... We analyzed the results of the studies using a mixed-methods approach, consisting of techniques from grounded theory, qualitative content analysis, and case studies. ... Since this study was exploratory and qualitative, the focus was not on internal validity. ...arXiv:1801.05366v1 fatcat:sj5sscin65a5tba6zweppqu5oi

The framework we employ al¬ lows us to analyze these data both quantitatively and with a methodology that combines quantitative and qualitative approaches. ... data is a technical achievement, but this effort can only pay off if there is a sensible framework for the analysis of such data. ...
Based on this, I will design middleware that combines models of the physical world with programming-language based assertions to help developers to design, develop, and debug robust CPS applications with ... Traditional debugging techniques can detect bugs in the cyber world, but bugs introduced from physical components and induced by limitations in the software interface to physical hardware are still difficult ... language that allows developers to capture both cyber and physical correctness; and (vi) builds a debugging framework that checks CPS assertions at run time. ...doi:10.1109/percomw.2014.6815195 dblp:conf/percom/Zheng14 fatcat:xi4oazfxorewlffiwvnysaa5ya

Several eye-tracking studies have investigated learners' debugging strategies though the literature lacks studies (a) conducted with early childhood preservice teachers and (b) that focus on block-based ... But most often, debugging was not informed by a hypothesis, which led to trial and error. Study limitations and directions for future research are discussed. ... Fourth, study participants worked on debugging activities individually. ...doi:10.37291/2717638x.20201132 fatcat:biz34gv4jng3vnjsb6b2l44dz4
Role of the Sponsor: The funding organization had no role in the design of the study beyond the critique offered by the peer-review process; and had no role in the conduct of the study, including the collection ... Debugging Qualitative studies can be done in series or in parallel with quantitative studies. ... Indeed, qualitative studies may be judged in part on whether they spark new ideas: if at the end of a qualitative study, one is still thinking precisely the same thoughts that one had when starting, then ...doi:10.1097/mpg.0b013e3182a025d8 pmid:23783009 pmcid:PMC3767397 fatcat:iqedfkglkrfktiuiamneg74jqi
One of the most important tasks in software maintenance is debugging. ... Using the SDI, we conducted a large study with professional developers to understand how developers set breakpoints. ... Study design The study consisted of two parts: (1) a qualitative evaluation using GV in a browser and (2) a controlled experiment on fault location tasks in a Tetris program, using GV integrated into Eclipse ...arXiv:1902.03520v1 fatcat:w2elasywurfgjntqxvfnwgizv4

To facilitate the design of a comprehensive evaluation approach, the CT framework of concepts, practices and perspectives developed by Brennan and Resnick (2012) was adopted in this study. ... A review of literature from 2010 onwards aimed to identify all studies related to CT evaluation to contribute to the development of appropriate evaluation components and methods for senior primary school ... The Adopted Framework for Computational Thinking Evaluation This study adopted a CT framework in the context of programming proposed by Brennan and Resnick (2012) as the evaluation framework. ...doi:10.1007/978-981-13-6528-7_8 fatcat:mnea5i4w2bdzvgmsbzoqkz5juy
The first one enables to create an evaluation protocol based on a knowledge database using two data mining algorithms, the "C4.5" to avoid from impossible combinations between devices and indicators and ... The aim of this work is to provide a framework allowing developers and experimenters to quickly evaluate 3DUIs and 3DITs during the design and the development lifecycle. ... Section 4 will present a case study applying the proposed Framework to evaluate an interaction technique. Conclusion and future work are given in section 5.

To this end, we propose a novel dense bottom-up framework: DEnse Bottom-Up Grounding (DEBUG). ... In this paper, we focus on natural language video localization: localizing (i.e., grounding) a natural language description in a long and untrimmed video sequence. ... But the bottleneck of DEBUG is the accuracy of boundary point in long video dataset. Qualitative Results. The qualitative results of DEBUG on ActivityNet Captions is illustrated in Figure 7 . ...doi:10.18653/v1/d19-1518 dblp:conf/emnlp/LuCTLX19 fatcat:s7n33mgy25c4rituwsuhvvycgq
It is widely held that debugging cyber-physical systems (CPS) is challenging; to date, empirical studies investigating research challenges in CPS verification and validation have not been done. ... This position paper then uses the findings from this study to highlight the discovered key challenges and to present a research trajectory to address these challenges. ... literature review, a quantitative on-line survey, and qualitative interviews. ...doi:10.1109/sescps.2015.11 dblp:conf/icse/ZhengJ15 fatcat:67yz2glwnzfqhprnbq55wsydke
Since scales limit attribute values in the objects, a qualitative form of constraint propagation on key attributes is achieved. Artificial Intelligence & Expert Systems Books 31723. ... A range of languages is studied: Pascal, SOLO, Lisp, Prolog and “Knowledge En- gineering Programming.” ...
In addition, a qualitative approach with an emphasis on filed observation was adopted to evaluate the instructional implementation of the maker education program. ... This study investigated elementary school students' learning performances and behaviors in a maker education program. ...
