  • ISSRE Workshops - Survivability modeling to assess deployment alternatives accounting for rejuvenation
    2015 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW), 2015
    Co-Authors: Gabriela Jacques-silva, Alberto Avritzer, Daniel Sadoc Menasche, Anne Koziolek, Lucia Happe, Sindhu Suresh
    Abstract:

    In this paper we apply survivability and software rejuvenation modeling to evaluate alternative software Architectures. We analyze failure history in two large industrial projects and propose a unified failure model to be used for the assessment of system survivability at the software Architecture Phase. Our goal is to assess the mean time to repair a system, conditioned that it starts from a failure prone state. To this aim, we use the failure model as one of the components of an analytical survivability framework which yields the desired metric of interest. The framework comprises a Phased-recovery model and a software rejuvenation model. We instantiate the proposed framework to analyze a data streaming system used as case study. Numerical investigation allows us to quantify the impact of Architecture deployment alternatives, Phased recovery and software rejuvenation on the mean time to repair.

  • developing software reliability models in the Architecture Phase of the software lifecycle
    International Symposium on Software Reliability Engineering, 2014
    Co-Authors: Alberto Avritzer, Andre B Bondi
    Abstract:

    We present an approach for software reliability modeling at the Architecture Phase that has been applied to a large complex industrial system. The practicality of the approach is supported by the ease of use and model simplicity, which followed from the failure data analysis and the system Architecture workflow modeling of this large and complex industrial system.

  • EASE - Security at software Architecture level: A systematic mapping study
    15th Annual Conference on Evaluation & Assessment in Software Engineering (EASE 2011), 2011
    Co-Authors: Ali Arshad, Muhammad Usman
    Abstract:

    Background: Non functional requirements (NFRs) are greatly influenced by the architectural choices and designs made during Architecture Phase. Security is an important concern in today's world in most applications. Security, like other NFRs, is also related with software Architecture. A lot of work is being reported to deal with security at Architecture level. Aim: This paper synthesizes the work that has been reported about security at Architecture level. Results: This paper reports a mapping study conducted to see the quantity and type of work reported about security at software Architecture level. Results show that most of the work in this area is about proposing and evaluating a solution. Conclusion: The mapping study identified the efforts that have been reported about security at Architecture level. The use of systematic mapping technique can bring a significant contribution to research areas and based on the systematic maps, not only state of art of an area can be identified at an abstract level but it can also suggest future directions for research.

  • The cotton HD-Zip transcription factor GhHB12 regulates flowering time and plant Architecture via the GhmiR157-GhSPL pathway.
    Communications biology, 2018
    Co-Authors: Tianyi Wang, Nian Liu, Lichen Wang, Xiangyin Luo, Xianlong Zhang, Longfu Zhu
    Abstract:

    Domestication converts perennial and photoperiodic ancestral cotton to day-neutral cotton varieties, and the selection of short-season cotton varieties is one of the major objectives of cotton breeding. However, little is known about the mechanism of flowering time in cotton. Here, we report a cotton HD-ZIP I-class transcription factor (GhHB12) specifically expressed in axillary buds, which antagonisticlly interacts with GhSPL10/13 to repress the expression of GhFT, GhFUL, and GhSOC1, resulting in bushy Architecture and delayed flowering under long-day conditions. We found that GhHB12-mediated ancestral upland cotton phenotypes (bushy Architecture and delayed flowering) could be rescued under short-day conditions. We showed that overexpressing of GhrSPL10 partially rescues the bushy Architecture and delayed flowering phenotypes, while overexpression of GhmiR157 reinforced these phenotypes in GhHB12-overexpressing plants. This study defines a regulatory module which regulates cotton Architecture, Phase transition and could be applied in the breeding of early maturing cotton varieties.

  • GhHB12, a HD-ZIP I Transcription Factor, Negatively Regulates the Cotton Resistance to Verticillium dahliae
    International journal of molecular sciences, 2018
    Co-Authors: Tianyi Wang, Wan Zhu, Yujing Wang, Longfu Zhu
    Abstract:

    The homeodomain-leucine zipper (HD-ZIP) is a plant-specific transcription factor family that plays important roles in plant developmental processes in response to multiple stressors. We previously isolated a cotton HD-ZIP class I transcription factor gene, GhHB12, which is regulated by the circadian clock and photoperiodism. Furthermore, it regulates cotton Architecture, Phase transition, and photoperiod sensitivity. Here we report that GhHB12 was induced by methyl jasmonate (MeJA) and Verticillium dahliae infection. Additionally, stress-responsive elements were found in the GhHB12 promoter. Promoter fusion analysis showed that GhHB12 was predominantly expressed in primary roots and that it was induced by mechanical damage. Overexpression of GhHB12 increased susceptibility of the cotton plant to the fungal pathogens Botrytis cinerea and V. dahliae, which was coupled with suppression of the jasmonic acid (JA)-response genes GhJAZ2 and GhPR3. Our results suggest that GhHB12, a cotton stress-responsive HD-ZIP I transcription factor, negatively regulates cotton resistance to V. dahliae by suppressing JA-response genes.

  • QUEST2: Project plan for preliminary analysis/system Architecture Phase (PA/SA)
    1995
    Co-Authors: F.d. Braaten
    Abstract:

    This Project Management Plan combines the project management deliverables from the P+ methodology that are applicable to this part of the QUEST2 work. This consolidation reflects discussions with WHC QA regarding an appropriate method for ensuring that P+ deliverables fulfill the intent of WHC-CM-3-10 and QR-19.

  • QUEST2: Sysdtem Architecture deliverable set
    1995
    Co-Authors: F.d. Braaten
    Abstract:

    This document contains the system Architecture and related documents which were developed during the Preliminary Analysis/System Architecture Phase of the Quality, Environmental, Safety T-racking System redesign (QUEST2) project. Each discreet document in this deliverable set applies to a analytic effort supporting the architectural model of QUEST2. The P+ methodology cites a list of P+ documents normally included in a ``typical`` system Architecture. Some of these were deferred to the release development Phase of the project. The documents included in this deliverable set represent the system Architecture itself. Related to that Architecture are some decision support documents which provided needed information for management reviews that occurred during April. Consequently, the deliverables in this set were logically grouped and provided to support customer requirements. The remaining System Architecture Phase deliverables will be provided as a ``Supporting Documents`` deliverable set for the first release.

  • QUEST2: Release 1, SA/Release 1 supporting documents deliverable set
    1995
    Co-Authors: F.d. Braaten
    Abstract:

    This document contains deliverables which reflect the last of the System Architecture Phase analysis for the Quality, Environmental, Safety Tracking System redesign (QUEST2) project. These deliverables are focused on the final insights required to start functional design of the first QUEST2 release. They include the data definitions, conversion rules, standards for design and user interface, performance criteria, and rules to be followed during the prototyping activity described in the Project Management Plan.
