Negative sequential patterns (NSPs) produced by negative sequence analysis (NSA) capture more informative and actionable knowledge than classic positive sequential patterns (PSPs) due to involving both occurring and nonoccurring items, which appear in many applications.

DNA Sequencing With Positive and Negative Errors
Journal of Computational Biology, 1999The problem addressed in this paper is concerned with DNA sequencing by hybridization. An algorithm is proposed that solves a computational phase of this approach in the presence of both positive and negative errors resulting from the hybridization experiment. No a priori knowledge of the nature and source of these errors is required.

Negative sequence impedance of converters
IEE Proceedings B Electric Power Applications, 1981The fundamental frequency behaviour of power convertors to unbalanced supply voltages is described in the paper. The model used caters for the effect of variable unbalance, variable firing angle, different firing systems, and the effect of a noninfinite DC reactance. The results are of use for a wide range of applications, such as HVDC and power drives.

A review of negative sequence current
2010 63rd Annual Conference for Protective Relay Engineers, 2010Sequence component analysis plays an essential role in analyzing power system faults and explaining some power system phenomena. It is very well known that negative sequence current could cause rotor damage, and that damage is highly detrimental to rotating machines such as motors and generators.

Negative priming and sequence learning
European Journal of Cognitive Psychology, 2002Three experiments used a novel sequence learning task, in which participants responded to changes in location of one visual stimulus whilst ignoring another. Experiment 1 demonstrated negative priming effects in this task, in that responses to individual sequence elements were disrupted when the attended stimulus (e.g., red asterisk) appeared at the ...

Calculation of negative-sequence losses and negative-sequence resistance of turbogenerators
IEEE Transactions on Power Apparatus and Systems, 1975The negative-sequence losses and their calculation are of great significance for large turbogenerators having high utilization factors. A generalized method for the determination of negative-sequence losses and negative-sequence resistance is given. With the help of equivalent circuits, accounting for all the given constructional particularities of the

Compensation of Negative Sequence Component using sequence parameters
2014 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2014], 2014Current unbalance is frequently encountered power quality problem. Negative sequence current leads to increase in machine temperature and unnecessary tripping of circuit breakers. Unequal phase current and harmonic current causes increased line losses and skin effect.

Negative obstacle detection from image sequences
SPIE Proceedings, 2011Negative obstacle detection has been a challenging topic. In the previous researches, the distance that negative obstacles can be detected is so near that vehicles have to travel at a very low speed. In this paper, a negative obstacle detection algorithm from image sequences is proposed.
