Significant Enhancement in the Seebeck Coefficient and Power Factor of p-type PEDOT: PSS through the Incorporation of n-type MXene.

ACS Applied Materials and Interfaces, 2020
Thermoelectric (TE) materials are important for the sustainable development because they can directly convert heat into electricity. Intrinsically conductive polymers have been attracting considerable attention because of their advantages over inorganic ...

Coefficients of Products of Powers of Eta Functions

The Ramanujan Journal, 2001
Define sequences \(b(m)\) and \(c(m)\), \(m=0,1,2\dots\), by \[ \sum_{m=0}^\infty b(m)q^m= \prod_{n=1}^\infty \frac{(1-q^n)^3} {(1-q^{2n})} \quad\text{and}\quad \sum_{m=0}^\infty c(m) q^m= \prod_{n=1}^\infty \frac{(1-q^{2n})^3} {(1-q^n)}. \] Let \(p\) be a prime.

Bootstrap power of the generalized correlation coefficient

Statistics and Computing, 1996
We present a bootstrap Monte Carlo algorithm for computing the power function of the generalized correlation coefficient. The proposed method makes no assumptions about the form of the underlying probability distribution and may be used with observed data to approximate the power function and pilot data for sample size determination. In particular, the

Maximum Efficiency Tracking for Wireless Power Transfer Systems With Dynamic Coupling Coefficient Estimation

IEEE transactions on power electronics, 2018
Maximum efficiency tracking is an important issue for wireless power transfer (WPT) system. Traditional maximum efficiency tracking method normally focuses on load impedance matching with fixed coupling condition.

Power quality coefficients for power electronic transformers

2016 17th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM), 2016
This paper proposes three basic configurations of power electronic transformer for distributive networks. Power electronic transformers have a number of essential advantages in comparison to power low-frequency transformers. The configurations proposed include different types of output inverters.

Study of Super-Lift Coefficient of Co-Flow Jet Airfoil and Its Power Consumption

AIAA Aviation 2019 Forum, 2019
This paper studies the super-lift coefficient of Co-Flow Jet (CFJ) airfoil and its power consumption. An optimized CFJ airfoil (CFJ6421-SST150-SUC247-INJ117) for cruise with enlarged injection slot size can achieve higher maximum lift coefficient than ...

Coefficients of powers of univalent functions

Complex Variables, Theory and Application: An International Journal, 1986
Let S be the usual class of normalized univalent functions. We write and consider the behaviour of the upper bounds An (λ) of the |an(λ)| for fψ S. If f(z) is the Koebe function an (λ)= bn (λ) where For λ = 1 de Branges has recently proved Bieberbach's conjecture that An (λ)= bn (λ) and his method extends at once to the case λ > 1.

Power series with i.i.d. coefficients

Statistics & Probability Letters, 2013
Abstract In this work we consider a power series of the form X = ∑ j = 0 ∞ δ j Z j where 0 δ 1 and { Z j } j ≥ 0 is an i.i.d. sequence of random variables. We show that X is well-defined iff E [ ( log | Z 0 | ) + ] ∞ and establish a ...
