Complex system analysis of the long term dynamics suggests that power transmission systems operate near a critical point. Here the effect of generator operation in a model for power systems is investigated. Two opposing methods of dispatching generators are compared. These two methods are to minimize and maximize the line flows with respect to their limits across the system. These methods are also compared to an economic dispatch. It is shown that the generator dispatch method used affects the frequency distributions and other statistics of blackouts. Dispatching using the maximization method causes a reduction in the frequencies of all blackouts as measured by the amount of load shed. This reduction is concurrent with an increase in the investment in the transmission system. These observations suggest that economic dispatch, while attempting to increase reliability, actually decreases the robustness of the system.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126534935","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}

We know of no other company doing this, yet it provides extreme visibility and control at the CXO level. It promotes agile thinking enterprise-wide, driving non-engineering departments to adopt Scrum. We believe it is making us more profitable.We estimate effort in team months, run quarterly Sprints, assign whole teams to projects, meet in weekly stand-ups. We start, postpone or cancel whole projects. Within individual projects, we still use 1-4 week Sprints and all the trappings of the classic Scrum process, including, in some cases, Scrum-of-Scrums.New challenges arise: Shared resource constraints suggest Kanban methods. Net Present Value can justify prioritization, but creates controversy. Moving teams between projects requires rapid programming environment setup. The process forces executives to justify decisions. We want simple improvement metrics, but they seem elusive.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128068467","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}

Our approach uses data derived from the version control system SVN (subversion) to retrieve the collaboration structures using an elaborate refinement process. The software `SVN Network Analysis Tool' (SVNNAT) aims to reveal the strengths and properties of collaboration ties between the developers in order to analyze their productivity and their quality of work in a given constellation of a software development network. In contrast to an earlier version of SVNNAT, our current approach accounts for the specific structures of programming languages in software code to separate technical artifacts from the information about the actors' collaboration in the development network. The result of the evaluation process is a social network of software developers that can be analyzed using typical indicators of topology properties like betweenness, closeness, and degree centralization. In a further step such network analysis can be used to propose an efficient network structure for developers of newly designed software projects.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128126722","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 using massively parallel processing on large malware program sets we can recognize common code sequences, such as loop constructs, if-then-else structures, and subroutine calls. We can also recognize common subroutine sequences. The Concordia architecture generalizes the recognized elements so they can be collected into invariant forms. The invariant forms can be used by the analyst to understand the program being analyzed. The invariant forms can also be used to classify large numbers of programs automatically.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122222439","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 reap maximum benefits from the methodology, businesses typically need to implement coordinated changes in development methodologies, tools, product architectures, organizational designs, and business models. Product lines are developed in complex international software ecosystems, but there is no coordinated set of international standards for defining and leveraging the methodology. As a result, ecosystems cannot adopt standardized methods and tools for developing product lines, tool vendors face difficulties in developing tools to enable product line engineering, and universities cannot effectively set up product line engineering courses because an internationally accepted curriculum is missing. The International Organization for Standardization has initiated several projects to create a set of international standards for software product line engineering. Practitioners, researchers, and other stakeholders can contribute to these projects through their national standards bodies. This paper discusses the projects and future directions for product line standardization.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121702183","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 process of adaptation, the commanders depend on information management systems for information. Yet there are still numerous reports of situations in which commanders had to make decisions based on incomplete, outdated or incorrect information, indicating poor information quality. In many of these situations, poor information quality can be attributed to the information management process incapable of adapting to external (environmental) changes and internal (team) information needs. Using dynamic capability theory and the findings of a case study, this paper presents four principles for information management adaptability: (1) maintain and update team memory, (2) dedicate resources for environmental scanning, (3) maximize the number of alternative information sources and (4) integrate forecasting and back casting methods in the information management process.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121768350","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}

How can the relationships among multiple ICTs be described and analyzed in a scalable way? In this study, we offer a scalable methodology, based on computational analysis of discourse, to examine the relationships among ICTs. Specifically, we employed Kullback-Leibler (KL) divergence to compare the semantic similarity of forty-seven ICTs discussed in the trade magazine InformationWeek over a decade. Using hierarchical clustering, we have found that the similarity of the technologies can be mapped in a hierarchy and similar technologies demonstrated similar discourses. The results establish the validity of our approach and demonstrate its scalability and richness. This analytical approach not only enables diffusion researchers to undertake multi-innovation, multi-source, and multi-period studies, but also helps practitioners effectively adopt and efficiently use new ICTs in their organizations.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115939756","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}

With the growth in these programs, the complexities in their management and control have also increased. One of the challenges faced by LRPs managers is that of developing models to address various forecasting issues to support short, medium, and long term planning and operational decision-making. We propose in this paper a predictive model of redemption and liability in LRPs. The proposed approach is an aggregate inventory model in which the liability of points is modeled as a stochastic process. An illustrative example is discussed as well as a real-life implementation of the methodology to facilitate use and deployment considerations in the context of a frequent flyer program, an airline industry based LRP.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113932016","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}

So far process modeling has been mainly performed with generic process modeling languages. These approaches have however limitations when it comes to the needs of specific problem domains or automated process analysis. Semantic building block based languages (SBBL) aim to overcome those limitations by integrating domain semantics in the modeling language. However, this class of languages is only useful if they exhibit the same expressiveness as generic languages. In this paper we strive to answer this question by comparing the expressiveness of the SBBL language PICTURE with ARIS as a generic language based on the Bunge-Wand-Weber ontology, showing that PICTURE has hardly construct deficits compared to ARIS while showing less construct redundancy and construct overload in its constructs.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131953169","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 energy storage and conversion system in PHEVs, given potentially high levels of future market penetration, represent a sizable dispersed energy storage resource or reactive power source that electric utilities could leverage to their benefit. In this investigation the impact of PHEVs utilized as reactive power resources on fault delayed voltage recovery on distribution systems is analyzed. It is known that fault delayed voltage recovery can cause serious problems on distribution circuits resulting in stalled air-conditioners, motor tripping and other load disruption events. The impact of these phenomena on the performance of distribution systems is documented with and without PHEVs present.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132041128","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}
