In the general case, multidimensional data means a table of numbers whose rows correspond to different objects and columns correspond to features characterizing the objects. Usually, the number of objects is large, and the dimensionality (number of features) is greater than it is possible to represent the objects as points in 2D. The goal is to reduce the dimensionality of data to such one that objects, characterized by a large number of features or by proximities between pairs of the objects, be represented as points in lower-dimensional space or even on a plane. Multidimensional scaling (MDS) is an often-used method to reduce the dimensionality of multidimensional data nonlinearly and to present the data visually. MDS minimizes some stress function. We have proposed in [8] and [9] to consider the stress function and multidimensional scaling, in general, from the geometric point of view, and the so-called Geometric MDS has been developed. Geometric MDS allows finding the proper direction and step size forwards the minimum of the stress function analytically. In this paper, we disclose several new properties of Geometric multidimensional scaling and compare the simplest realization (GMDS1) of Geometric MDS experimentally with the well-known SMACOF version of MDS.","PeriodicalId":255059,"journal":{"name":"Proceedings of the 2021 European Symposium on Software Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128600967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of these rules can be automated and supervised using software systems that interact with connected devices such as smart cameras, motion sensors, smart door locks, etc. Given the critical nature of a pandemic prevention application, it seems essential to use techniques such that the possibility of failures is minimised. The integration of formal reasoning within software development is obviously a way to achieve this goal. Unfortunately, often formal methods are deemed too difficult and hence their application is somehow limited. This study builds on real-life pandemic prevention strategies, and shows how a formal method and domain-specific languages can be mixed in a lightweight development process. Our approach extends Meeduse, a language workbench that embeds an animator and model-checker and allows one to define proved executable Domain-Specific Languages (xDSLs) using the B method. In addition to the benefits of using xDSLs together with a formal approach during the development process the originality of this work is two-fold: (1) first, we propose a novel refinement-based approach that allows DSL developers to produce several versions of the application without breaking down the global safety properties; and (2) second, we use the verified specification of the DSL semantics at runtime so that the implementation effort is highly reduced.","PeriodicalId":255059,"journal":{"name":"Proceedings of the 2021 European Symposium on Software Engineering","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116175680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measuring this distance is challenging as the welding arc complicates the usage of conventional distance measurements without positional offset in-process. For that reason, this study investigated and evaluated the usage of several sensors (wire feed sensor, current and voltage sensor, microphone, welding camera, spectrometer, structural acoustic sensor) for a direction independent in-process measurement. Features were extracted based on domain knowledge and selected by means of a correlation analysis. The spectrometer (Pearson’s r = −0.90) showed the most robust measurements for stable process parameters when computing the relative intensity at a wavelength of 960 nm, followed by the welding camera (Pearson’s r = 0.84) when analyzing the images with a convolutional neural network. Based on the findings, a closed-loop-control was created. As a system identification revealed a high impact of the welding speed on the track height in comparison to the wire feed rate (Pearson’s r − 0.90 < > − 0.16), the closed-loop-control was realized by means of a simple P-control for the welding speed. The proposed approach enabled the manufacturing of multi-layer multi-bead parts with multi-axes deposition paths.","PeriodicalId":255059,"journal":{"name":"Proceedings of the 2021 European Symposium on Software Engineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123880433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in developing countries, such as those in the Middle East, Agile is still in the early stages of adoption compared to Europe and North America. This is problematic, specifically in the case of Saudi Arabia, which is increasingly looking at the software industry to diversify its economy to reduce the reliance on the oil industry. It is essential to understand the factors that influence the decision of Saudi software organisations to adopt Agile. Hence, this study aims to critically review the influential factors identified in the Agile adoption framework that may support or challenge the adoption of Agile in small and medium-sized enterprises (SMEs) in Saudi Arabia. To this end, we carried out a focus group study with five software practitioners working in different Saudi software SMEs. The main findings indicate the apparent influence of all the identified factors in the developed framework except those related to process, with a high level of importance attached to culture, people and knowledge factors. This study refines the framework and helps software organisations assess their readiness for adopting Agile during the development process.","PeriodicalId":255059,"journal":{"name":"Proceedings of the 2021 European Symposium on Software Engineering","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123954302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This affects the software industry significantly because SSCs dominate the industry, and most of all, over 80 percent of software products are produced by SSCs. This cross-sectional survey was conducted in 3 countries attracting 115 respondents with the primary objective of investigating the software practice concerning the utilization of process tools in SSCs. The study focused on the tools used in requirements engineering and software testing as critical process areas for quality software products. Our findings indicate that the number of personnel intertwines with the complexities arising from lengthy procedures of the tools and processes, aggregating into difficulty in tool usage. Due to the constant evolution of practices, the volatility in processes also causes slow adoption of other tools, for instance, testing that must accompany the main engineering tools during a project. These findings are significant in informing theory and communicating to the practitioners what they should do regarding process tools.","PeriodicalId":255059,"journal":{"name":"Proceedings of the 2021 European Symposium on Software Engineering","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127904631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
