Test Mass Ring Dampers with Minimum Thermal Noise
Advanced laser interferometers gravitational wave detectors may need to substantially reduce the Q-factor of test mass normal modes to eliminate parametric instability. In this paper we investigate various ring damper configurations for two different laser beam geometries. We show that there is a well defined location near the mid point of a test mass where the thermal noise degradation from th...
متن کاملSome Conditions for Characterizing Minimum Face in Non-Radial DEA Models with Undesirable Outputs
The problem of utilizing undesirable (bad) outputs in DEA models often need replacing the assumption of free disposability of outputs by weak disposability of outputs. The Kuosmanen technology is the only correct representation of the fully convex technology exhibiting weak disposability of bad and good outputs. Also, there are some specific features of non-radial data envelopment analysis (DEA...
متن کاملMinimum degree conditions for cycles
In this note we discuss the lengths of cycles which are forced to exist in an n-vertex graph with minimum degree δ. We show that for any integer k ≥ 2 there exists n0 such that if n ≥ n0 and G is an n-vertex graph with δ(G) = δ ≥ n/k then the following are true. (i) G contains Ct for every even 4 ≤ t ≤ ⌈ n k−1 ⌉ , (ii) either G is in a known exceptional class or G contains Ct for every odd t ∈ ...
متن کاملThe commutative Moufang loops with minimum conditions for subloops I
The structure of the commutative Moufang loops (CML) with minimum condition for subloops is examined. In particular it is proved that such a CML Q is a finite extension of a direct product of a finite number of the quasicyclic groups, lying in the centre of the CML Q. It is shown that the minimum conditions for subloops and for normal subloops are equivalent in a CML. Moreover, such CML also ch...
متن کاملminimum flows in the total graph of a finite commutative ring
let $r$ be a commutative ring with zero-divisor set $z(r)$. the total graph of $r$, denoted by$t(gamma(r))$, is the simple (undirected) graph with vertex set $r$ where two distinct vertices areadjacent if their sum lies in $z(r)$.this work considers minimum zero-sum $k$-flows for $t(gamma(r))$.both for $vert rvert$ even and the case when $vert rvert$ is odd and $z(g)$ is an ideal of $r$it is s...
