Fuzzy Discrete Event Systems under Fuzzy Observability and a test-algorithm
[article]
2007
arXiv
pre-print
In order to more effectively cope with the real-world problems of vagueness, impreciseness, and subjectivity, fuzzy discrete event systems (FDESs) were proposed recently. ...
Also, we use this computing method to check the existence of supervisors in the Controllability and Observability Theorem of classical discrete event systems (DESs), which is a new method and different ...
S P / G equals the degree of s belonging to the prefix-closure of the fuzzy language marked by the supervised fuzzy system S P / G under the effect of observable projection. ...

Scheduling tests for VLSI systems under power constraints
1997
IEEE Transactions on Very Large Scale Integration (vlsi) Systems
Second, the test compatibility graph is used to identify a complete set of time compatible tests with power dissipation information associated with each test. ...
This paper considers the problem of testing VLSI integrated circuits in minimum time without exceeding their power ratings during test. We use a resource graph formulation for the test problem. ...
This is the same system under test as before, except that the test length of each node is different. ...

Tapir: Automation Support of Exploratory Testing Using Model Reconstruction of the System Under Test
[article]
2018
arXiv
pre-print
A screen-flow-based model of the tested system is incrementally reconstructed during the exploratory testing process by tracking testers' activities. ...
Compared with the exploratory testing approach, which is manually performed in two case studies, the proposed framework allows the testers to explore a greater extent of the tested system and enables greater ...

Design and Implementation of System Under Test for LTE Protocol Conformance Testing
2015
Journal of Communications
However, all the test suites developed in TTCN-3 language can not be run without building up a development environment which should connect with the System Under Test (SUT), the target to be tested. ...
The main idea is that the software SUT implemented in TTCN level needs not to simulate all the details of the System Simulator and UE depicted in standard test environment, but only implements some necessary ...

Sequential Testing Policies for Complex Systems Under Precedence Constraints
2012
Social Science Research Network
We study the problem of sequentially testing the components of a multi-component system to learn the state of the system, when the tests are subject to precedence constraints and with the objective of ...
A solution is a testing policy, which is a set of decision rules that describe in which order to perform the tests. ...
Summary In this paper, we have examined different classes of testing policies for k-out-of-n systems under general precedence constraints. ...

System for automated fatigue crack growth testing under random loading
1985
International Journal of Fatigue
Procedures have been developed for computer-controlled crack propagation testing under random load sequences. ...
They include certain features which are not available in conventional systems, but which appear essential for random load testing. ...
Crack extension under such loading occurs predominantly under the larger load cycles. ...

Testing pearl millet and cowpea intercropping systems under high temperatures
2018
Field crops research (Print)
As testing a complex adaptation strategy in controlled environments is difficult, conducting field experiments in the dry season offers opportunities to test cropping systems under extreme but real-world ...
We conclude that successful intercropping systems must be highly specific to conditions and demands. ...

A Two-Plan Sampling System for Life Testing Under Weibull Distribution
2010
Industrial Engineering & Management Systems
A two-plan sampling system is proposed for a failure-censored life testing when the lifetime follows a Weibull distribution with known shape parameter. ...
It has been observed that the proposed system requires only a single failure for the observation. ...
A single sampling plan under a failure censored (type-II) or a time censored (type-I) scheme is usually adopted for a life testing. ...

Test model coverage analysis under uncertainty: extended version
2021
Journal of Software and Systems Modeling
AbstractIn model-based testing, we may have to deal with a non-deterministic model, e.g. because abstraction was applied, or because the software under test itself is non-deterministic. ...
Consequently, performing precise test analyses, e.g. to calculate the test coverage, are not possible.. ...
As a running example, consider the labelled transition system (LTS) in Fig. 1 as a model of some system under test (SUT). The system interacts with its environment through actions a, b, and c. ...

IEICE transactions on information and systems
The increased test data volume requires more tester memory and test application time, and both result in test cost inflation. ...
Small delay defects are becoming possible sources of test escapes, and high delay test quality and therefore a greater volume of test data are required. ...
Let T MC and T C be system clock timing and test timing, respectively. ...

Nonlinear damping quantification from phase-resonant tests under base excitation
2022
Mechanical systems and signal processing
We validate the developed method first in virtual experiments of a friction-damped and a geometrically nonlinear system, and then in a physical experiment involving a thin beam clamped at both ends via ...
Phase-resonant testing has emerged as an important method for this task, as it substantially reduces the amount of data required for the identification compared to conventional frequency-response testing ...
If the structure under test is light compared to the total moving mass (including the shaker armature and the slip table, if applicable), the dynamic forces generated within the structure under test are ...
