Scenario Synthesis from Imprecise Requirements [chapter]

Bill Mitchell, Robert Thomson, Paul Bristow
2005 Lecture Notes in Computer Science  
The paper defines a formal semantics that characterizes a particular type of imprecise compositional semantics derived from industrial case studies, and a process algebra that describes the valid requirements  ...  A further difficulty is caused by the imprecise nature of industrial requirements specifications.  ...  This leads to a technique for synthesising phase composition processes from a collection of requirements scenarios.  ...

The Use of Bayesian Networks to Assess the Quality of Evidence from Research Synthesis: 1

Gavin B. Stewart, Julian P. T. Higgins, Holger Schünemann, Nick Meader, Neil R. Smalheiser
2015 PLoS ONE  
We tested the model using a range of plausible scenarios that guideline developers or review authors could encounter. Results Overall, the model reproduced GRADE judgements for a range of scenarios.  ...  These responses are then entered into the Bayesian network to ascertain the probabilities of risk of bias, inconsistency, indirectness, imprecision and publication bias conditional on review characteristics  ...  This requires evaluation of biases across studies, as well as biases detected during the process of evidence synthesis.  ...

Impreciseness and Its Value from the Perspective of Software Organizations and Learning [chapter]

Grigori Melnik, Michael M. Richter
2004 Lecture Notes in Computer Science  
Traditionally, this is not the case for statements which are imprecise in the sense of being vague or subjective.  ...  For this purpose we relate abstraction, uncertainty and impreciseness to each other by investigating the differences and common properties.  ...  Extract the imprecise statements from this conver sation. 3.  ...

The use of the possibility theory to investigate the epistemic uncertainties within scenario-based earthquake risk assessments

Jeremy Rohmer, Cedric Baudrit
2010 Natural Hazards  
Unlike randomness, epistemic uncertainty stems from incomplete, vague or imprecise information. This source of uncertainties still requires the development of adequate tools in seismic risk analysis.  ...  We propose to use the possibility theory to represent three types of epistemic uncertainties, namely imprecision, model uncertainty and vagueness due to qualitative information.  ...  Therefore, adequate formal tools for their assessment and incorporation are required (Ferson and Guinzburg 1996) .  ...

Exploiting intellectual properties with imprecise design costs for system-on-chip synthesis

Byoung-Woon Kim, Chong-Min Kyung
2002 IEEE Transactions on Very Large Scale Integration (vlsi) Systems  
This paper presents an intellectual property (IP)-based system-on-chip (SoC) synthesis framework focusing on how to select IPs from different sources and how to integrate the selected IPs using on-chip  ...  Furthermore, the framework must exploit IPs with imprecise design costs, e.g., imprecise area, energy consumption, execution time, design time, and design quality, because IPs are developed in different  ...  Imprecise Design Costs of IPs As shown in Fig. 1 , the impreciseness 1 of design cost comes from the fact that an IP is used in various target environments of IP integrators, which can be different from  ...

From requirements to partial behavior models

Ivo Krka
2010 Proceedings of the eighteenth ACM SIGSOFT international symposium on Foundations of software engineering - FSE '10  
In this thesis, I will improve the state-of-the-art for capturing, analyzing, and refining functional requirements by providing support for synthesizing, analyzing, and refining Modal Transition Systems  ...  An example flaw is an implied scenario (i.e., undesirable required behavior) that can appear as a consequence of imprecise specification.  ...  The resulting component MTSs comprise required behavior from the positive scenarios and maybe behavior which does not conflict the negative scenarios and operational requirements.  ...

CINeMA: An approach for assessing confidence in the results of a network meta-analysis

Adriani Nikolakopoulou, Julian P. T. Higgins, Theodoros Papakonstantinou, Anna Chaimani, Cinzia Del Giovane, Matthias Egger, Georgia Salanti
2020 PLoS Medicine  
The evaluation of the credibility of results from a meta-analysis has become an important part of the evidence synthesis process.  ...  CINeMA considers 6 domains: (i) within-study bias, (ii) reporting bias, (iii) indirectness, (iv) imprecision, (v) heterogeneity, and (vi) incoherence.  ...  There are 'no concerns' if the confidence interval is entirely on one side of the no effect line (imprecision scenario 3 in Fig 3) , or if it is entirely within the area of equivalence (imprecision scenario  ...

The Mechanism of Human Nonhomologous DNA End Joining

Michael R. Lieber
2007 Journal of Biological Chemistry  
Part of this heterogeneity arises from the diversity of the DNA ends, but much of it arises from the many alternative ways in which the nuclease, polymerases, and ligase can act during NHEJ.  ...  Pathologically, the imprecision of NHEJ contributes to genome mutations that arise over time.  ...  The template-independent synthesis by pol is the likely basis for occasional antigen receptor junctional additions in lymphocytes from animals in which TdT has been knocked out (25, 26) .  ...
