The Selective Catalytic Reduce (SCR) is studied. The unknown parameters of the SCR kinetic model equations are fitted based on the Genetic Algorithm (GA), which is in the range of the allowable error, compared to the experimental data. Then in AVL Boost software, the simulation results of SCR reaction are obtained. Compared to the test data, the simulation results prove that the parameter ident...

1. Background Formulated in the late 1970s to specify the requirements of the Operational Flight Program (OFP) of the A-7 aircraft 8], the SCR (Software Cost Reduction) requirements method is a method based on tables for specifying the requirements of software systems. During the 1980s and the early 1990s, many companies, including Bell Laboratories, Grumman, Ontario Hydro, and Lockheed, applie...

Tabular expressions and the Software Cost Reduction (SCR) method are table-based specification techniques. Both of them were successfully used in practice, especially to formally specify software requirements. Tabular expressions have rather precise semantics, while SCR semantics are more intuition based. In this paper, we want to improve SCR semantics. For that, we show how to convert the SCR ...

This paper investigates the robustness of the Solvency Capital Requirement (SCR) when a log-normal reference model is slightly disturbed by the heaviness of its tail distribution. It is shown that situations with “almost” lognormal data and a rather important variation between the “disturbed” SCR and the reference SCR can be built. The consequences of the estimation errors on the level of the S...

This paper seeks to raise awareness on the SCR extensions derived from industry use, and discusses how an integration of Software Cost Reduction (SCR) modeling concepts address current limitations in the System Modeling Language (SysML) standard. The paper describes an integration of a formal requirement modeling approach based the SCR method with the SysML structure mechanisms providing an alt...

A steel catenary riser (SCR) attached to a floating platform at its upper end encounters fluctuations in and near its touchdown zone (TDZ), which causes the interaction with the seabed. Subsea surveys and the analysis of SCR’s indicated that the greatest stress and highest damage occurred near the touchdown point (TDP), where the SCR first touches the seabed. Nowadays, the linear seabed spring ...

There is conflicting evidence as to whether awareness is required for conditioning of the skin conductance response (SCR). Recently, Schultz and Helmstetter (2010) reported SCR conditioning in contingency unaware participants by using difficult to discriminate stimuli. These findings are in stark contrast with other observations in human fear conditioning research, showing that SCR predominantl...

We analyzed skin conductance response (SCR) as a psychophysiological index to evaluate affective aspects of consumer preferences for cosmetic products. To examine the test-retest reliability of association between preferences and SCR, we asked 33 female volunteers to complete two experimental sessions approximately 1 year apart. The participants indicated their preferences in a typical paired c...
