It is required that in-situ pressure of hydrothermal fluids should be maintained before analyzing. For this reason, gas-tight samplers with accumulator attached on the sample chamber have been developed. Pre-charged gas in the accumulator is used for compensating decompression of sample caused by its volume change during withdrawing onboard. Besides the structure of the sampler, pre-charged internal...
Time-related properties are a critical type of extrafunctionalrequirements for designing real-time systems. Modeling and validating time-related properties at therequirements specification and analysis phases is important forthe successful development of real-time systems in terms of cost, quality and productivity. In the literature and practice, timinganalyses (e.g., Worst Case Execution Time) are...
An analytical model is proposed to describe the on-state current in linear and saturation regions for the high-voltage C-SenseFET. As C-SenseFET is an important sensing and charging integrated device, two key parameters–-sensing ratio K and charging swing factor α are analyzed in detail and some optimizational structures are provided. For the practical application of C-SenseFET, K and α are required...
To reduce the cost and risk of the development of system of systems (SoS) by pre-evaluation before the SoS is built, a model-driven approach is proposed to evaluate the SoS based on its architecture, especially focused on measures of performance and effectiveness. In order to implement the pre-evaluation, the system architecture needs to be transformed to the simulation model of the system under the...
Several variance analysis methods that are used in fault localization based on program behaviors were analyzed and compared. None of these methods takes into account the features of object-oriented programs, thus, could not be used accurately in fault localization in object-oriented programs. The present study proposed that when doing variance analysis, object behaviors could be described by using...
