The Golay complementary sequences (GCSs) over 22μ-quadrature amplitude modulation (QAM) constellation are investigated (integer μ ≥ 2), based on the binary standard generalized Boolean functions (GBFs). We develop a sufficient condition so as to produce 22μ-QAM GCSs. Different from the known 22μ-QAM GCSs, the proposed ones are educed by binary signals instead of quaternary signals. Hence, the resultant...
Statistical fault localization techniques find suspicious faulty program entities in programs by comparing passed and failed executions. Existing studies show that such techniques can be promising in locating program faults. However, coincidental correctness and execution crashes may make program entities indistinguishable in the execution spectra under study, or cause inaccurate counting, thus severely...
A general approach to the kinematics modeling and analyses of articulated all-terrain rovers traversing uneven terrain is describes in this paper. In addition, caster and camber are taken into consideration. Based on a four wheel rover, the model is derived for full 6 DOF motion, enabling movements in the, and directions, as well as rotations of pitch, roll and yaw. Differential kinematics is derived...
Based on concatenating iteration, multiple complementary sequence sets which are orthogonal each other are proposed. Each complementary sequence set of the constructed multiple sets is composed of multiple complementary sequences with each complementary sequence containing a flock of element sequences. The complementary sequences in the same complementary sequence set possess ideal auto-correlation...
In continuous integration, a tight integration of test case prioritization techniques and fault-localization techniques may both expose failures faster and locate faults more effectively. Statistical fault-localization techniques use the execution information collected during testing to locate faults. Executing a small fraction of a prioritized test suite reduces the cost of testing, and yet the subsequent...
Fault localization is a major activity in software debugging. Many existing statistical fault localization techniques compare feature spectra of successful and failed runs. Some approaches, such as SOBER, test the similarity of the feature spectra through parametric self-proposed hypothesis testing models. Our finding shows, however, that the assumption on feature spectra forming known distributions...
