Criptografia em segurança de arquivos confidenciais
… await every Computer Center: fraud, hardware and software failures, operator errors, programming errors, penetration of private informations and others, are briefly discussed. With reference of privacy of information, the classical cryptographic techniques are studied. On this bases, suitable …

Software dependability in the operational phase
Software quality should be built-in and maintained throughout the software life cycle, which requires understanding of software dependability in actual environments. This thesis discusses how to develop analysis techniques for evaluating the dependability of operational software using real …

High Performance Computing Issues in Large-Scale Molecular Statics Simulations
… in programs to the implementation of software tools which create an environment that aids sharing of high performance hardware resources and limits losses caused by hardware and software failures. In this thesis we describe our approach to meeting these challenges in the context of a …

A novel invariants-based approach for automated software fault localization
Software bugs are everywhere. Not only do they infest software during development, but they escape our extermination efforts and enter production code. In addition to severe frustration to customers, software failures result in billions of dollars of lost revenue to service providers. The most …

Designing an experiment to study absorption vs. dose for feedback enabled radiation therapy
… to correctly register dose during hardware or software failures; all of which result in radiation treatments being measured after the procedure or in a fault susceptible manner during the procedure. The integrating feedback f-center dosimeter (IF2D) is a dosimeter that would address these …

Reusing software tests for configuration testing: A case study of the Hadoop project
Configuration is an inseparable piece of today’s software development. Due to its dynamic nature and lack of standardized checking procedure, misconfiguration has been one of the dominant factors contributing to software failures in production and wide spread outages. Existing techniques (static …

On the Viability of Quantitative Assessment Methods in Software Engineering and Software Services
… is important to an IT service provider since software failures are inevitable and their timing is difficult to predict. In this research, a cost model for help desk operations is developed. The cost model relates predicted incidents to labor costs using real help desk data. Incidents are …

Problems in GPS Accuracy
… in the signal such as low signal to noise ratio, software failures, or physical obstruction of the signals. These slips propagate to errors in user positioning. Cycle-slip detection and repair are crucial to maintaining accurate positioning. Linear regression models and sequential hypothesis …

Innovation of a design method (MoIST) that incorporates non-traditional 'soft' systems science into traditional 'hard' information systems design
… literature has identified some weaknesses in the software development methodologies. These weaknesses include premature design decisions taken before major requirements are known. Another is the dearth of options for applying Systems Science and information systems design techniques in a UMLbased …

Test-driven fault navigation for debugging reproducible failures
The correction of software failures tends to be very cost-intensive because their debugging is an often time-consuming development activity. During this activity, developers largely attempt to understand what causes failures: Starting with a test case that reproduces the observable failure they …

Hybrid Causal Logic Methodology for Risk Assessment
… factors in addition to hardware and software failures and adverse conditions of the physical environment. The causal modeling should also extend to the influence of regulatory and oversight functions. This research offers such a methodology. It proposes a multi-layered modeling …

Higher Availability of Services in Heterogeneous Distributed Systems
… for the development of highly available software services. The research focuses on failover functionality and heterogeneous distributed systems that are based on client/server architecture. Failover is the migration of services from one server to another. If one server in the distributed …

An Analysis of the Effect of Environmental and Systems Complexity on Information Systems Failures
… information systems developments are successful. Software project failure is frequent and lamentable. Surveys and statistical analysis results underscore the severity and scope of software project failure. Limited research relates software structure to information systems failures. Systematic …

Addressing production run failures dynamically
The high complexity of modern software, and our pervasive reliance on that software, has made the problems of software reliability increasingly important. Yet despite advances in software engineering practice, pre-release testing, and automated analysis, reports of highsoftware engineering …
