Enskog-Landau kinetic equation for multicomponent mixture. Analytical calculation of transport coefficients [PDF]

open access: yes, 2000
The Enskog-Landau kinetic equation is considered to describe non-equilibrium processes of a mixture of charged hard spheres. This equation has been obtained in our previous papers by means of the non-equilibrium statistical operator method.

Analytical Method for Calculating Sustainable Airport Capacity [PDF]

open access: yesSustainability, 2020
Capacity is the attitude of an airport to manage a number of operations in a given time interval within a fixed maximum delay (and under given safety conditions). Capacity studies are commonly carried out on five levels of analysis according to the required detail in order to identify the best option that balances economic, logistic and safety issues ...

Higgs-photon associated production at $e\bar{e}$ colliders

open access: yes, 1995
We present complete analytical expressions for the amplitudes of the process $e\bar{e}\rightarrow H\gamma$. The calculation is performed using nonlinear gauges, which significantly simplifies both the actual analytical calculation and the check of its ...

Average diagonal entropy in non-equilibrium isolated quantum systems [PDF]

open access: yes, 2016
The diagonal entropy was introduced as a good entropy candidate especially for isolated quantum systems out of equilibrium. Here we present an analytical calculation of the average diagonal entropy for systems undergoing unitary evolution and an external

Optimizing an analytical dose calculation algorithm for fast 2D calculations

open access: yesZeitschrift für Medizinische Physik, 2010
Previously, an analytical dose calculation algorithm for MLC-based radiotherapy was developed and commissioned, which includes a detailed model of various MLC effects as a unique feature [1]. The algorithm was originally developed as an independent verification of the treatment planning system's dose calculation and it explicitly modeled spatial and ...

On the efficient computation of high-order derivatives for implicitly defined functions

open access: yes, 2009
Scientific studies often require the precise calculation of derivatives. In many cases an analytical calculation is not feasible and one resorts to evaluating derivatives numerically. These are error-prone, especially for higher-order derivatives.

Throughput analysis of S/R shuttle systems and ideal geometry for high performance [PDF]

open access: yesFME Transactions, 2016
Shuttle systems are used in high performance automated storage/retrieval unit load systems. Each storage level is serviced by one transfer car. There is a lift for storage and retrieval on the front side of the load system.

Analytical Calculation of Annular Gap Throttling of Damping Valve [PDF]

open access: yesMATEC Web of Conferences, 2020
For the throttling characteristics of the suspension system damping valve, an analytical method for gap throttling based on turbulent flow state was proposed for the first time. The boundary layer theory was used to give the expression of the three-layer
