Economical evaluation of large-scale photovoltaic systems using Universal Generating Function techniques [PDF]

open access: yesJournal of Modern Power Systems and Clean Energy, 2013
Solar energy plays an important role in the global energy framework for future. Comparing with conventional generation systems using fossil fuels, the cost structure of photovoltaic (PV) systems is different: the capital cost is higher while the ...

Generating functions for the universal Hall-Littlewood $P$- and $Q$-functions [PDF]

open access: yes, 2018
Recently, P. Pragacz described the ordinary Hall-Littlewood $P$-polynomials by means of push-forwards (Gysin maps) from flag bundles in the ordinary cohomology theory. Together with L.

Towards the third generation universities: The core innovative function approach [PDF]

open access: yesMedical Journal of The Islamic Republic of Iran, 2021
Background: Undoubtedly, economic and social value added depends on the functions of universities. Moving toward third-generation universities (3rd GU) is an inevitable process. These universities need different functions than traditional ones; therefore, identifying and determining their functions is essential. The purpose of this study is to collect,

Renormalization flow for unrooted forests on a triangular lattice [PDF]

open access: yes, 2007
We compute in small temperature expansion the two-loop renormalization constants and the three-loop coefficient of the beta-function, that is the first non-universal term, for the sigma-model with O(N) invariance on the triangular lattice at N=-1.

Approximate Analysis of Multi-State Weighted k-Out-of-n Systems Applied to Transmission Lines

open access: yesEnergies, 2017
Multi-state weighted k-out-of-n systems are widely applied in various scenarios, such as multiple line (power/oil transmission line) transmission systems where the capability of fault tolerance is desirable. However, the complex operating environment and

Universal Generating Function Based Probabilistic Production Simulation Approach Considering Wind Speed Correlation

open access: yesEnergies, 2017
Due to the volatile and correlated nature of wind speed, a high share of wind power penetration poses challenges to power system production simulation. Existing power system probabilistic production simulation approaches are in short of considering the ...

Universal Functions on Complex General Linear Groups

open access: yesJournal of Approximation Theory, 1999
Let \(S\) be a Stein manifold, and denote by \(\mathcal A(S)\) the set of all holomorphic functions on \(S\). For a compact set \(K \subset S\), the \(\mathcal A(S)\)-hull \(\widehat{K}\) of \(K\) ist defined by \[ \widehat{K} := \{ x \in S : |f(x)|\leq \sup_K{|f|} \text{ for all } f \in \mathcal A(S) \} , \] and \(\mathcal A(K)\) denotes the set of ...

Reliability Assessment of Random Uncertain Multi-State Systems

open access: yesIEEE Access, 2019
The random uncertain multi-state system is defined as a multi-state system consisting of multi-state components whose performance rates and the corresponding state probabilities are presented as uncertain variables. Reliability assessment of random multi-
