متن کاملRepresentative Delay Measurements (RDM): Facing the Challenge of Modern Networks
Network access technologies have evolved significantly in the last years. They deploy novel mechanisms like reactive capacity allocation and time-slotted operation to optimize overall network capacity. From a single node’s perspective, such optimizations decrease network determinism and measurement repeatability. Evolving application fields like machine to machine (M2M) communications or real-t...
متن کاملLifetime Measurements in 178Hf
Lifetimes of levels from K(π) = 2(+), K(π) = 4(+) and several K(π) = 0(+) bands have been measured in the (178)Hf nucleus using the GRID technique. Lifetimes of the 2(+) and 3(+) levels were measured within the K(π) = 2(+) γ band. A lower limit was established for the lifetime of the 4(+) level of the K(π) = 4(+) band. The resulting upper limits for the absolute B(E2) values exclude collective ...
متن کاملLifetime measurements in Tl
Lifetimes are reported for the 6s6p P1, 6s6d D2 and 6s7s S0 levels in Hg-like Tl II, measured using beam-foil excitation. The values obtained were τ(P1) = 0.59 ± 0.02 ns, τ(P1) = 39 ± 2 ns, τ(D2) = 6.5 ± 0.5 ns, and τ(S0) = 3.0 ± 0.4 ns. Isoelectronic trends for line strengths of the resonance and intercombination transitions are studied through comparisons with earlier measurements for Hg I–Bi...
متن کاملTrends in Lifetime Measurements
The interpretation of lifetime measurements and new characterization techniques are addressed in this paper. Parameters such as surface/interface recombination, sample thickness, and injection level are discussed. Novel characterization techniques using frequency-dependent capacitance, conductance, or impedance measurements are described and are shown to be useful for thin layer, e.g., epitaxia...
