It does not require to create a new font file for every distinctive style because it can automatically produce a variety of font styles. Therefore, this advantage of METAFONT can also be applied to the complex characters such as CJK (Chinese-Japanese-Korean). The output generated by METAFONT is TeX-based bitmap font such as Generic Font (GF) along with font metrics file. Such fonts cannot be used outside the TeX-based environments. In this paper, a module named TeX Bitmap Font Module is proposed for FreeType font engine. FreeType supports outline and bitmap fonts but it doesn't support TeX related fonts such as GF. TeX Bitmap Font Module enables the direct usage of TeX-based bitmap font such as GF. It also provides a direct support of METAFONT and GF inside FreeType on Linux environment.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130726173","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}

By a programming perspective, context is often used implicitly, and context-aware code is fragmented in the codebase. In Context-Oriented Programming, instead, context is considered a first-class citizen and is explicitly used to modularise context-sensitive functionality and behavioural variability. In this paper, we reflect on the role of context in collective adaptive systems, by a discussion from the special perspective of a macro paradigm, Aggregate Programming, which supports the specification of collective behaviour by a global perspective through functional compositions of field computations. In particular, we consider the abstractions exposed in Context-Oriented and Aggregate Programming, suggest potential synergies in both directions, and accordingly take the first steps towards a combined design.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124206937","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}

The research community has proposed a variety of approaches to automate resource scaling, placement decisions, failure recovery, parameter tuning and many other tasks enabling the self-management of micro-services. Evaluating these approaches in a realistic scenario requires a reference application that offers a range of different behaviors, as well as the necessary degrees of freedom. Existing reference applications either build on an outdated technology stack, do not implement a micro-service architecture or do not have a realistic performance behavior. Production software can usually not be used to evaluate research methods as researchers rarely have access to production software. In this demonstration we showcase the TeaStore, a micro-service reference application with a state-of-the-art technology stack. The TeaStore consists of five services with diverse performance behavior and can be used to evaluate the applicability of novel self-management approaches for micro-services and autonomic software systems in general. We give an overview of the TeaStore architecture, show different deployment options, describe how to run different load profiles and lastly how to collect monitoring data.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121112430","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}

Especially in the context of a set of self-adaptive systems working together in an overall system-of-systems, integration is a very complex task due to the limited predictability of system behaviour. In this position paper, we argue that one approach to tackle the problem can be found in an adaptive coordination of autonomous adaptive systems. Therefore, we characterise existing coordination approaches and identify four research challenges that need to be addressed. We use the scenario of platooning of autonomous vehicles to demonstrate the resulting challenges.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126779362","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}

In the context of selfhealing systems (SHS), employing simulators has been shown to be the most dominant means for performance evaluation. Simulating a SHS also requires realistic fault injection scenarios. We study the state of the practice for evaluating the performance of SHS by means of a systematic literature review. We present the current practice and point out that a more thorough and careful treatment in evaluating the performance of SHS is required.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116712345","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}

Algorithms were evaluated under uncertainty of 4 different dynamic parameters, considering 400 experimental scenarios and taking into account an average objective function cost as evaluation criterion. Experimental results indicate that two-phase algorithms considering predictionbased VMPr Triggering and update-based VMPr Recovering methods are best suited for power consumption minimization.","PeriodicalId":368308,"journal":{"name":"2019 IEEE 4th International Workshops on Foundations and Applications of Self* Systems (FAS*W)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121401950","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}
