Le travail hospitalier psychiatrique, comme celui de l’hôpital général, réunit des acteurs formations, statuts et milieux sociaux très différents qui œuvrent concert à la prise en charge patients. Or, les logiques hiérarchique économique ont engendré une délégation cascade, renforcée par distribution officielle officieuse tâches. Ainsi, l’application du soin est déléguée le psychiatre l’infirmi...

A new data fusion method called joint probability density matrix (JPDM) is proposed, which can associate and fuse measurements from spatially distributed heterogeneous sensors to identify the real target in a surveillance region. Using the probabilistic grids representation, we numerically combine the uncertainty regions of all the measurements in a general framework. The NP-hard multisensor da...

We present a new proof of the quantum Cramer-Rao bound for precision parameter estimation [1–3] and extend it to a more general class of measurement procedures. We analyze a generalized framework for parameter estimation that covers most experimentally accessible situations, where multiple rounds of measurements, auxiliary systems or external control of the evolution are available. The proof pr...

The efficiency of the MLE is demonstrated indirectly by using the following theorem. Theorem [7, p. ZSS]: If an estimator exists such that equality is satisfied in the Cramer-Rao inequality, it can be determined as a solution of the maximum likelihood equation. We will show that such an estimator exists. This implies that the covariance matrix of the MLE is given by the inverse of the Fisher in...

The paper deals with the problem of development of the effective time delay difference estimator of beat signals, obtained by processing the frequency modulated signals. Such beat signals can be formed by the heterodyne scheme of receiver of linear frequency modulated signals with internal coherence. The described problem is actual in many radar applications such as radio direction finding. The...

The Cramer-Rao Lower Bound is widely used in statistical signal processing as a benchmark to evaluate unbiased estimators. However, for some random variables, the probability density function has no closed analytical form. Therefore, it is very hard or impossible to evaluate the Cramer-Rao Lower Bound directly. In these cases the characteristic function may still have a closed and even simple f...

Violence and assaults by residents against staff or other residents in the long-term care system are a major public health concern. Direct care workers in long-term care facilities (LTCs) are the workers at highest risk to suffer from workplace violence (eg, grabs, chokes, hair pulls, kicks, hits, bites) and injury as a result of interactions with residents. Aggressive behavior in the form of t...
