There exist many application domains of cyber-physical systems such as autonomous systems, process control systems, robotic systems, and context-aware systems. The physical world is a complex and continuous world that changes in real-time while the computational world is a simplified and discrete world that often stores a delayed, likely inaccurate image of the physical world using sensory data. The mismatch between these two worlds poses unique challenges of developing software for cyber-physical systems. In this paper, we mainly (1) illustrate this mismatch problem by presenting difficulties that we faced during two projects of developing software for cyber-physical systems: the self-adaptive robot car project and iSpace project; (2) systematically analyse the reason for the mismatch problem based on our first-hand experiences; (3) summarize a general methodology on how to partly bridge the gap between the two mismatched worlds to better develop software for cyber-physical systems based on the knowledge learned from the two projects. We expect that these experiences can help others in better design and develop cyber-physical systems and can be used to explore new techniques (such as new testing techniques) to improve the quality of cyber-physical systems.","PeriodicalId":362187,"journal":{"name":"Proceedings of the 5th Asia-Pacific Symposium on Internetware","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122567496","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}

Furthermore, they can perform complex computations which are usually resource-intensive and consuming, e.g., data analytic application and augmented reality games. Mobile devices might suffer from their limited computing capabilities and resources. As mobile devices now are gaining access through excellent connectivity with much more powerful cloud-side services, and offloading can be a potential solution. This paper presents the design and implementation of the AppMobiCloud system for improving mobile web applications by leveraging the mobile-cloud convergence. At development time, AppMobiCloud employs a combination of profiling and points-to analysis. This facilitates application developers to find the computation-intensive code fragments, and specifies whether they can be offloaded with some constraints. At runtime, AppMobiCloud migrates the chosen JavaScript code fragments from the mobile devices for remote execution. It synchronizes client-side application runtime context and constructs the \"cloned\" context at server, executing the codes there and re-integrating the result back to the mobile device. We evaluate our approach on three well-known JavaScript benchmarks, Dromaeo, V8 and Kraken, and a typical computation-intensive AI game. The evaluation demonstrates that our work can reduce JavaScript application's execution time and energy consumption respectively on mobile devices up to 98% and 83%.","PeriodicalId":362187,"journal":{"name":"Proceedings of the 5th Asia-Pacific Symposium on Internetware","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130137359","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}

To reduce uncertainty and boost collaborations in such setting, it is important to provide trustworthiness evaluation mechanisms so that trustworthy partners/entities can be easily found. In this work, we propose a novel trustworthiness evaluation mechanism by enhancing existing mechanisms with similarity and non-negative constraints. To be specific, we first extend an existing multi-aspect trust inference model by incorporating the non-negative constraint. One of the advantages of such constraint is its strong interpretability. Second, we incorporate similarity into two neighborhood models borrowed from recommender systems. When computing similarity, we make use of the intermediate results from the first step. Finally, these models are combined under a machine learning framework. To show the effectiveness of our method, we conduct experiments on a real data-set. The results show that: both our non-negativity extension and similarity computation improve the evaluation accuracy of the original methods, and the combined method outperforms several state-of-the-art methods.","PeriodicalId":362187,"journal":{"name":"Proceedings of the 5th Asia-Pacific Symposium on Internetware","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129455062","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 a smart space, as new providers may come in and existing ones may leave from time to time, the collection of available component services may change dynamically, resulting in broken compositions. Automatic reselection or recomposition mechanisms can be applied to fix broken compositions. However, they may introduce extra efforts and time and there are applications requiring (composed)services to be continuously available (at least) during a period of time, otherwise the applications would break down. Both the situations affect users' experience. If we could know how long each component service would be continuously available, we could optimize the composition process by reducing the frequency of broken compositions. In this paper we propose a scheme to achieve the goal. It utilizes presence-patterns of providers to estimate how long a component service may continuously available and it always selects the most continuously available composition that matches requirements. Simulations are carried out to show how and how well the presence-patterns based scheme work.","PeriodicalId":362187,"journal":{"name":"Proceedings of the 5th Asia-Pacific Symposium on Internetware","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128073426","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}

An emerging software paradigm named Internetware was proposed to handle openness, dynamism of software systems in the context of Internet. An Internetware system is composed of self-adaptive and cooperative entities, which impliedly requires autonomy. How to construct a system equipped with these features brings challenge to developers. Autonomic computing that intends to tackle the self-management issues of complex system is helpful to deal with the development and evolution of Internetware software, but the original model of autonomic element in the area can only be used to make a system autonomic. Hence, in this paper, we extend the model of autonomic elements as a basic construct to support the design and construction of Internetware software. Then we compose an architecture for Internetware entity out of extended elements to support constructing Internetware systems. The architecture describe the essential structure of an Internetware entity and make it and most of its modules performing self-adaptiveness and cooperativity possible, which makes our works different from most of those related. A case study is conducted to illustrate our approach and show its applicability.","PeriodicalId":362187,"journal":{"name":"Proceedings of the 5th Asia-Pacific Symposium on Internetware","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126471683","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}

An important problem related to the development of Internetware applications is how to define their requirements. Traditional requirements modeling methods work well with software applications deployed in predictable environment, but cannot deal with Internetware applications, which have to identify and adapt themselves to the unpredictable situations of their environment. The self-adaptation characteristic of Internetware applications introduces challenges to the effective modeling of the requirements of Internetware applications. In this paper, we carry out a preliminary study on requirements modeling methods for self-adaptive software systems. In particular, we focus on how existing requirements modeling methods address the challenges caused by self-adaptation and what are the advantages and disadvantages of their solutions. By doing this study, we aim to identify the essential capabilities or properties that a requirements modeling method should possess so as to support the requirements modeling of self-adaptive software systems like Internetware.","PeriodicalId":362187,"journal":{"name":"Proceedings of the 5th Asia-Pacific Symposium on Internetware","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121055495","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}
