Attack Models

Approaches for securing digital assets of information systems can be classified as active approaches based on attack models, and passive approaches based on system-models. Passive approaches are inherently superior to active ones. However, taking full advantage of passive approaches calls for a rigorous standard for a low-complexity-high-integrity execution environment for security protocols. We sketch broad outlines of mirror network (MN) modules, as a candidate for such a standard. Their utility in assuring real-world information systems is illustrated with examples.

3D Content

Managing capital oil and gas and civil engineering facilities requires a large amount of heterogeneous information that is generated by different project stakeholders across the facility lifecycle phases and is stored in various databases and technical documents. The amount of information reaches its peak during the commissioning and handover phases when the project is handed over to the operator. The operational phase of facilities spans multiple decades and the way facilities are used and maintained have a huge impact on costs, environment, productivity, and health and safety. Thus, the client and the operator bear most of the additional costs associated with incomplete, incorrect or not immediately usable information. Web applications can provide quick and convenient access to information regardless of user location. However, the integration and delivery of engineering information, including 3D content, over the Web is still at its infancy and is affected by numerous technical (i.e. data and tools) and procedural (i.e. process and people) challenges. This paper addresses the technical issues and proposes a Web3D enabled information integration framework that delivers engineering information together with 3D content without any plug-ins. In the proposed framework, a class library defines the engineering data requirements and a semi-structured database provides means to integrate heterogeneous technical asset information. This framework also enables separating the 3D model content into fragments, storing them together with the digital assets and delivering to the client browser on demand. Such framework partially alleviates the current limitations of the JavaScript based 3D content delivery such as application speed and latency. Hence, the proposed framework is particularly valuable to petroleum and civil engineering companies working with large amounts of data.

The Given

The chapter intends to propose a hybrid cryptosystem based on a chaotic map and a fractal function. The sequential order of process execution provides a computationally less expensive and simple approach that still designed a secure cryptosystem. A one-dimensional Ricker map and its modified form are employed to initially shuffle the image pixels twice, and also a pseudo-random sequence is generated using both maps. The algorithm implemented a sequence of pixel confusion-diffusion steps using the image rotation and a transcendental anti-Mandelbrot fractal function (TAMFF) and its Mann-iterated fractal function (Sup-TAMFF). Finally, the pixel value of an image obtained in the last step and the recent two pixels of the encrypted image is XORed with the corresponding pseudo-random matrix value to get the cipher image. Subsequently, various performance tests are conducted to verify the suitability of the given method to be used in real-world information transmission.

Data Elements

Real-world information, knowledge, and procedures after which information systems are modeled are generally of dynamic nature and subject to changes, due to the emergence of new requirements or revisions to initial specifications. E-government information systems (eGIS) present a higher degree of volatility in their environment, since requirement changes may stem from multiple sources, including legislation changes, organizational reforms, end-user needs, interoperability, and distribution concerns, etc. (Jansen, 2004; Prisma Project, 2002; Scholl, Klischewski, & Moon, 2005. To this end, the design and implementation of eGIS must adhere to paradigms and practices that facilitate the accommodation of changes to the eGIS as they occur in the real world. Object-oriented technologies have been extensively used to encapsulate reusable, tailorable software architectures as a collection of collaborating, extensible object classes; however the inherent conflict between software reuse and tailorability has inhibited the development of frameworks and models that would effectively support all requirements exposed by eGIS (Demeyer, Meijler, Nierstrasz, & Steyaert, 1997). The lack of such frameworks has lead to eGIS that cannot easily be adapted to the new requirements, mainly because only the predetermined specifications are taken into account and design decisions are fixed during the implementation phase (Stamoulis, Theotokis, Martakos, & Gyftodimos, 2003). A key issue to a viable solution eGIS modeling is the provision of the ability to multiple public authorities (PAs) to represent different aspects of the same real-world entity, while maintaining at the same time information consistency. Aspect representation is not only limited to data elements that describe the particular entity, but may extend to behavior alterations, when the entity is examined in different contexts. For example, an entity representing the citizen is expected to assume the behavior of beneficiary, when used in the context of the Ministry of Social Security, and the behavior of taxpayer, when accessed from the Ministry of Finance’s eGIS. Distinct behaviors may rely on different data representations and/or respond differently in requests. In this work we present a role-based modeling and implementation framework, which can be used for building eGIS and we argue that this model promotes the tailorability and maintainability of eGIS.

This work aims to make use of information technology to improve present test platform, proposing TPIF(Test Process Integration Framework) as an integrated interaction framework for enginer, quality controller, corporate vendor, and manager to test data and analyze information. Also, it suggests a practicable system framework and implementation case to illustrate the integration and reconciliation degree of TPIF. In TPIF, a component utilizes ATML as the basic format for test information is designed to transform ATML message to Web Services rapidly, upgrading the reliability of test information and be a reference for relevant research. The implication of this proposed framkwork is to mature the integration of test imformation; besides, the engineers could have better understanding of the completed status in production process through combining ATML and information flow , as well as enhancing the yield rate and reduce the possibility of damage.

Why would a person who is terrified of cockroaches use them in a math lesson? The idea for this investigation did not occur to me until I read a newspaper article that described Italian scientist Paolo Domenici's research about cockroaches' escape trajectories. In particular, he found that cockroaches have preferred escape trajectories of 90, 120, 150, and 180 degrees from the source of danger (Domenici et al. 2008). Because this real-world information presents a unique problem-solving context for fifth graders to explore angles formed by clockwise and counterclockwise rotations, I overcame my fear of the creatures to develop this investigation.

e18314 Background: There is limited real-world information on the utilization of TPO-RAs, eltrombopag (ELT) and romiplostim (ROM), for the treatment of ITP. Methods: The study employed a retrospective, longitudinal cohort design using integrated healthcare claims data from July 2008-June 2015. Adults diagnosed with ITP initiating TPO-RA therapy from Jan 2009-July 2014 were included. Patients not continuously enrolled in benefits for 6-months prior and 12-months post the index date (first TPO-RA claim date) were excluded. Index TPO-RA discontinuation rates, concomitant therapy, restarts, subsequent therapy, and treatment free periods were assessed. Results: Of the 1,067 patients included, 26.5% (283) received ELT and 73.4% (784) ROM. Age (58.8 vs 59.3; P= 0.705) and gender (males: 45.9% vs 46.6%; P= 0.858) were similar between cohorts. Among ELT and ROM patients 35.7% and 27.6% continued therapy (no gap of ≥30 days) for ≥1 year ( P= 0.010). The average duration of continuous therapy (up to gap ≥30 days) was 131 and 108 days, respectively ( P= 0.001). During continuous course of index TPO-RA treatment 52.7% ELT and 47.2% ROM patients received concomitant ITP-related treatment ( P= 0.115). Following discontinuation, 42.9% of ELT patients restarted ELT, 22.0% did not initiate any subsequent ITP treatments, and 35.2% started a new ITP treatment. Among patients who discontinued ROM, 38.4% restarted, 26.9% did not receive any subsequent therapy, and 34.7% initiated a new treatment. Treatment free periods (≥30 days with no ITP treatment) were experienced by 52.7% of ELT patients and 61.6% ROM patients ( P= 0.009). Mean duration of treatment free period was 109 and 137 days ( P< 0.001), respectively. Conclusions: ITP patients receiving ELT had a longer duration of treatment and shorter treatment free periods compared to patients receiving ROM. Further research is needed to compare clinical outcomes (e.g., platelet counts, bleeding symptoms and remissions) among ITP patients receiving ELT and ROM, in the real-world setting.
