Measurement of trace chemical impurities in ice cores contributes to the reconstruction of records of the atmospheric environment and of the climate system. Ion chromatography (IC) is an effective analytical technique for ionic species in ice cores but has been used on discretely prepared ice samples, resulting in extensive and slow sample preparation and potential for contamination. A new tech...

The continuous transformation of the US military into an integrated and a dominant “full spectrum” capability requires a comprehensive and evolutionary system model (the objective) and a prescribed set of transformation processes (the means) whose incremental results are measurable against operational requirements. Given its sheer size and complexity, this military system must be partitioned in...

Sampled-data H∞ control of linear systems is considered. The measured output is sampled and the only restriction on the sampling is that the distance between sequel sampling times does not exceed a given bound. A novel performance index is introduced which takes into account the sampling rates of the measurement and it is thus related to the energy of the measurement noise. Three types of contr...

continuous care team has a significant role in the treatment of chronic psychiatric patients and hence mental health services. this article retrospectively studied 55 patients of continuous care system at the shahid esmaily psychiatric center. results showed that compared to three years before intervention, during three years post intervention relapse rates, days of hospitalization (90%) and co...

In quantum physics, recent investigations deal with the so-called ”quantum trajectory” theory. Heuristic rules are usually used to give rise to “stochastic Schrödinger equations” which are stochastic differential equations of non-usual type describing the physical models. These equations pose tedious problems in terms of mathematical justification: notion of solution, existence, uniqueness, jus...

This work addresses the design and performance evaluation of a control system for a class of continuous stirred tank reactors to produce homopolymers via free radicals. The control system claims to be of practical implementation in the sense that: (i) it manages both measurement types existing in this class of processes: continuous-instantaneous, and discrete-delayed with a periodic sampling-ti...

The phenomenal growth of power system network both in terms of geographical sprawl as well as technological advancements, it requires tools for dealing with the system, wide disturbances that often cause widespread catastrophic blackouts in power system networks. When a major disturbance occurs, protection and control measures play the most important role to prevent further degradation of the s...

We study the dynamics of classical and quantum systems undergoing a continuous measurement of position by schematizing the measurement apparatus with an infinite set of harmonic oscillators at finite temperature linearly coupled to the measured system. Selective and nonselective measurement processes are then introduced according to a selection of or an average over all possible initial configu...
