text: "Wie ist der derzeitige Wissensstand in der Gemeinwesenarbeit? Das Handbuch
systematisiert und aktualisiert das Theorie- und Praxiswissen für dieses Gebiet.
Vorgestellt werden Traditionen und Diskussionen insbesondere in Deutschland, Österreich
und der Schweiz.\r\n\r\nIn der Praxis stellt sich Gemeinwesenarbeit einerseits
als Arbeitsprinzip und als Fachkonzept dar, das an Aktualität gewonnen hat, andererseits
aber zwischen Sozialraumorientierung und aktivierendem Sozialstaat zu verschwimmen
droht. Die AutorInnen arbeiten daher das Konzept Gemeinwesenarbeit historisch
auf und überprüfen es daraufhin, welche Beiträge es für eine fachtheoretische
Weiterentwicklung der Sozialen Arbeit aktuell einbringen kann. Es werden die verschiedenen
Handlungsfelder der Gemeinwesenarbeit betrachtet, nicht mit dem Ziel einer „Leistungsschau“,
sondern vielmehr als kritische Würdigung."

text: In this paper we study the existence of locally most powerful invariant tests
(LMPIT) for the problem of testing the covariance structure of a set of Gaussian
random vectors. The LMPIT is the optimal test for the case of close hypotheses,
among those satisfying the invariances of the problem, and in practical scenarios
can provide better performance than the typically used generalized likelihood
ratio test (GLRT). The derivation of the LMPIT usually requires one to find the
maximal invariant statistic for the detection problem and then derive its distribution
under both hypotheses, which in general is a rather involved procedure. As an
alternative, Wijsman’s theorem provides the ratio of the maximal invariant densities
without even finding an explicit expression for the maximal invariant. We first
consider the problem of testing whether a set of N-dimensional Gaussian random
vectors are uncorrelated or not, and show that the LMPIT is given by the Frobenius
norm of the sample coherence matrix. Second, we study the case in which the vectors
under the null hypothesis are uncorrelated and identically distributed, that is,
the sphericity test for Gaussian vectors, for which we show that the LMPIT is
given by the Frobenius norm of a normalized version of the sample covariance matrix.
Finally, some numerical examples illustrate the performance of the proposed tests,
which provide better results than their GLRT counterparts.

text: In this paper, we study the multiple-input multiple-output two-way relay channel
(MIMO-TWRC) when the nodes and relay use analog beamforming. Following the amplify-andforward
(AF) strategy, the problem consists of finding the transmit and receive beamformers
of the nodes and relay (as well as the power allocated to each one) that achieve
the boundary of the optimal rate region. To solve it, we first express the optimal
node beamformers in terms of relay beamformers and then show that the optimal
rate region can efficiently be characterized using convex optimization techniques.
We also extend our study to the multiple-relay scenario when the source nodes
are single antenna and propose a distributed algorithm to compute the relay beamforming
matrices. The proposed algorithm consists of solving two different subproblems.
First, each individual TWRC is optimized independently. Next, a distributed beamforming
is applied to make the signals from the relays add up coherently at the source
nodes. Numerical examples are provided to illustrate the performance of the proposed
techniques and to compare the performance of analog beamforming architectures
against conventional MIMO schemes that operate at the baseband.

text: In this paper we provide an efficient procedure to compute the total number
of degrees of freedom (DoF), achievable by linear beamforming, of the $K$-user
multiple-input multiple-output (MIMO) interference channel with an arbitrary number
of Tx-Rx antennas at each link. Firstly, we derive an analytical outer bound that
generalizes the results that exist for the symmetric $K$-user $M\timesN$ interference
channel. Secondly, we obtain a tighter bound by solving a convex optimization
problem that includes as constraints the DoF characterizations for point-to-point
MIMO links and for 2-user interference channels. The solution to this convex problem
admits an interesting waterfilling interpretation. Finally, exploiting this outer
bound and using a recently proposed feasibility test, we show that it is possible
to obtain the DoF for any interference channel in an efficient way. Some simulations
results are included to illustrate the tightness of the derived bounds, as well
as to study the DoF achievable for the 4-user channel when we distribute the total
number of antennas among users and between transmitters and receivers in different
ways.

text: This paper gives a solution to the problem of verifying stability of networks
consisting of integral input-to-state stable (iISS) subsystems. The iISS small-gain
theorem developed recently has been restricted to interconnections of two subsystems.
For large-scale systems, stability criteria relying only on gain-type information
that were previously developed address only input-to-state stable (ISS) subsystems.
To address the stability problem involving iISS subsystems interconnected in general
structure, this paper shows how to construct Lyapunov functions of the network
by means of a sum of nonlinearly rescaled individual Lyapunov functions of subsystems
under an appropriate small-gain condition.

text: This work presents a variation of canonical correlation analysis (CCA), where
the correlation coefficient between the instantaneous power of the projections
is maximized, rather than between the projections themselves. The resulting optimization
problem is not convex, and we have to resort to a sub-optimal approach. Concretely,
we propose a two-step solution consisting of the singular value decomposition
(SVD) of a "coherence" matrix followed by a rank-one matrix approximation. This
technique is applied to blindly recovering signals in a model that is motivated
by the study of neuronal dynamics in humans using electroencephalography (EEG)
and magnetoencephalography (MEG). A distinctive feature of this model is that
it allows recovery of amplitude-amplitude coupling between neuronal processes.

text: 'Two concerns often arise simultaneously when applying linear estimation in
communication systems: the computational complexity can be prohibitively high
when the system size is large, and the performance may degrade dramatically when
the presumed model is mismatched with the actual system. In this paper, we introduce
a subspace expansion framework to jointly address these concerns, in which the
observation is first projected onto a lower-dimensional subspace and then the
solution of the projected problem is regularized. We discuss two projection methods
based on eigensubspace and Krylov subspace expansions. We show that the Krylov
subspace projection provides an economical solution to regularized linear estimation.
We also compare different regularization methods, such as principal components
and diagonal loading. We show that diagonal loading generally outperforms other
alternatives and that Krylov subspace rank reduction can yield a regularization
effect close to diagonal loading. Finally, we investigate the impact of preconditioning
on the performance and complexity for mismatched modeling and propose a loaded
preconditioner, which can reduce complexity as well as preserve the regularization
effect. Under the proposed framework, various regularization schemes are studied
and some guidelines for choosing the right scheme are provided.'

text: This article is concerned with global asymptotic stability (GAS) of dynamical
networks. The case when subsystems are integral input-to-state stable (iISS) has
been recognized as notoriously difficult to deal with in the literature. In fact,
the lack of energy dissipation for large input denies direct application of the
small-gain argument for input-to-state stable (ISS) subsystems. Here for networks
consisting of iISS subsystems it is demonstrated that a two-phase approach allows
us to make use of the ISS small-gain argument by separating a trajectory into
a transient and a subsequent convergence. In contrast to the previous iISS results,
the two-phase approach immediately leads to a sufficient criterion for GAS of
general nonlinear networks in a matrix-like form (order condition).

text: Two similar stability notions are considered; one is the long established
notion of convergent systems, the other is the younger notion of incremental stability.
Both notions require that any two solutions of a system converge to each other.
Yet these stability concepts are different, in the sense that none implies the
other, as is shown in this paper using two examples. It is shown under what additional
assumptions one property indeed implies the other. Furthermore, this paper contains
necessary and sufficient characterizations of both properties in terms of Lyapunov
functions.

text: This paper provides sufficient conditions for the incremental stability of
time-delayed nonlinear systems. It relies on the Razumikhin-Lyapunov approach,
which consists in invoking small-gain arguments by treating the delayed state
as a feedback perturbation. The results are valid for multiple delays, as well
as bounded time-varying delays. We provide conditions under which the limit solution
of a time-delayed nonlinear system to a periodic (resp. constant) input is itself
periodic and of the same period (resp. constant). As an illustration, a specific
focus is given on a class of delayed Lur’e systems.

text: Separable Lyapunov functions play vital roles, for example, in stability analysis
of large-scale systems. A Lyapunov function is called max-separable if it can
be decomposed into a maximum of functions with one-dimensional arguments. Similarly,
it is called sum-separable if it is a sum of such functions. In this paper it
is shown that for a monotone system on a compact state space, asymptotic stability
implies existence of a max-separable Lyapunov function. We also construct two
systems on a non-compact state space, for which a max-separable Lyapunov function
does not exist. One of them has a sum-separable Lyapunov function. The other does
not.
