Collisional {delta}f method [PDF]
, 1997 A general method for including various collisional effects, such as the drag and diffusion of test particles due to background plasmas, the effect of particle source and sink, and the like-particle Coulomb collisions, is presented. The marker density g is generally unknown along the particle trajectory, and its evaluation depends on the way particles ...

Democratic Confidence Intervals for comparing two Proportions [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2013 We offer methods to create an accurate graph for comparing confidence intervals for two proportions. The firstmethod involves using weighted sum contrasts when fitting logistic regression with a binary explanatory variable.

A Penalized Likelihood Approach to Parameter Estimation with Integral Reliability Constraints
Entropy, 2015 Stress-strength reliability problems arise frequently in applied statistics and related fields. Often they involve two independent and possibly small samples of measurements on strength and breakdown pressures (stress).

Study of Star-Delta Soft Switch to Extend AC Motor High Speed Operation Region
CES Transactions on Electrical Machines and Systems, 2023 In traction application, speed range of motor is an important index for motor drives. In AC motor control, the maximum speed of the motor is limited by the output voltage capability of the traditional three-phase inverter with star connenction of ...

Delta methods in enveloping rings
Journal of Algebra, 1990 Let L be a Lie algebra over a field K of characteristic 0 with a universal enveloping algebra U(L) (or a restricted Lie algebra with restricted enveloping algebra u(L) when char K\(=p>0)\) and let L act on a K-algebra R as K-derivations. The authors consider the twisted smash products R{\#}U(L) and R{\#}u(L).
