Conflict Detection on Models An Empirical Study
نویسندگان
چکیده
Software Configuration Management (SCM) systems are employed to facilitate collaboration on software engineering artifacts such as models. Therefore, they need to detect concurrent change – also known as conflict detection. However, many researchers recognized that conflict detection on models is not well supported in traditional SCM systems since they are engineered for textual files. Their conflict detection shows many false positives, and they require a merge every time the same the same file is changed. Operation-based conflict detection and merging have been proposed to overcome these problems and reduce false positives. In this paper, we present an empirical study to compare traditional file-based, textual conflict detection with operation-based conflict detection on models. We compare two different strategies of file-based with two operation-based strategies in a multi-case study. We show that operationbased conflict detection results in fewer conflicts and thus requires fewer merges.

Detection of Outliers and Influential Observations in Linear Ridge Measurement Error Models with Stochastic Linear Restrictions
The aim of this paper is to propose some diagnostic methods in linear ridge measurement error models with stochastic linear restrictions using the corrected likelihood. Based on the bias-corrected estimation of model parameters, diagnostic measures are developed to identify outlying and influential observations. In addition, we derive the corrected score test statistic for outliers detection ba...
متن کاملDetection of perturbed quantization (PQ) steganography based on empirical matrix
Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...
متن کاملData envelopment analysis in service quality evaluation: an empirical study
Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a sing...
متن کاملAutomating the Detection of Complex Semantic Conflicts between Software Requirements(An empirical study on requirements conflict analysis with semantic technology)
Keeping requirements consistent already at early project stages is a main success factor for software development projects. However, manual requirements conflict analysis takes significant effort and is error-prone. Requirement engineers and other project participants such as technical architects use different terminologies (due to different domain backgrounds) which makes automation of conflic...
متن کاملConflict and Performance in Channels: A Comparative Synthesis of Empirical Findings
We conduct a comprehensive meta-analysis of the literature on the role of channel conflict in channel performance. In particular, we assess the existing empirical evidence to compare two rival views of conflict. In the first view, conflict is a residual outcome of business processes that reduces joint profit and is efficiency depleting. Reduction or elimination of conflict is the firms’ objecti...
