Therefore, one of the main features of the tool is that, for a given number of reflections and temporal resolution, it allows us to study the VLC signal propagation inside any simulation environment, regardless of its geometric shape, size (area), number of obstacles in its interior, etc., with a high computational efficiency.
As the crystal's repeating unit, its unit cell, becomes larger and more complex, the atomic-level picture provided by X-ray crystallography becomes less well-resolved (more "fuzzy") for a given number of observed reflections.
A finite set R ⊂ R d ∖ { 0 } is called a root system if R ∩ R. α = and σ α R = R for all α ∈ R. For a given root system ℛ the reflections σ α, α ∈ R, generate a finite group W ⊂ O ( d ), called the reflection group associated with ℛ.
Specifically, (3) r s = γ 0 + γ e tan θ, where γ0 is a parameter that is initially set to the r.m.s.d. of the Ewald offset calculated for all the reflections on a given image, γ e represents the width of the energy spread and the unit-cell variation (the initial value of γ e is calculated from the average energy spread), and θ is the Bragg angle.
A not so trivial question to answer is what fraction of incident radiation is reflected for any given Bragg reflection and why.
Examples of visualization are given for reflection from a rigid plane, radiation from a two-way loudspeaker system, and diffraction by a barrier with a slow-waveguide filter.
Also, "soft" expenses that aren't really paid for in cash, but give a reflection of the expensing of assets over time (like depreciation expense), show up on the income statement but don't on the statement of cash flow.
This is a particularly poignant moment for such reflection, given scores of companies are converging on New York over the next few days to join Volkswagen in making commitments during Climate Week to creating a low-carbon economy.
