Traditionally the tuning of dynamic matrix control (DMC) type multivariable controllers is done by trial and error. The APC engineer chooses arbitrary starting values and tests the performance on a simulated controller. The engineer then either increases the values to suppress movement more, or decreases them to have the manipulated variables move faster. When the controller performs acceptably...

Consider a list of n files whose popularities are random. These files are updated according to the move-tofront rule and we consider the induced Markov chain at equilibrium. We give the exact limiting distribution of the search-cost per item as n tends to infinity. Some examples are supplied.

Intrusive thoughts and attempts to suppress them are common, but while suppression may be effective in the short-term, it can increase thought recurrence in the long-term. Because intentional suppression involves controlled processing, and many aspects of controlled processing decline with age, age differences in thought suppression outcomes may emerge, especially over repeated thought suppress...

Suppressing noise in physical systems is of fundamental importance. As quantum computers mature, error correcting codes (QECs) will be adopted order to suppress errors any desired level. However the noisy, intermediate-scale (NISQ) era, complexity and scale required adopt even smallest QEC prohibitive: a single logical qubit needs encoded into many thousands qubits. Here we show that, for cruci...

The present paper investigated the effect of teacher’s follow‐up move approach on Iranian EFL learners’ conversation quality. Ninety students were selected in a senior high school in Poldokhtar, Iran. Through an oral test sixty out of ninety students whose scores were between one standard deviation (SD) above and below the mean were selected as the participants of the study. Then they were divi...

The current study compared thought suppression, focused attention (mindfulness) and unfocused attention as strategies for managing spider fear. Spider fearful participants were exposed to a strategy induction before completing a Behavioural Approach Test (BAT). The BAT is a 10 step measurement of how close participants are willing to move towards a spider. Participants were instructed to use wh...

Wigner Distribution, one of many methods to compute time frequency representation, satisfies large number of mathematical properties and gives optimal energy concentration in time frequency plane. However, Wigner distribution suffers from severe cross-term interference problem, which limits its scope for practical applications. Different modified versions of Wigner distribution have been develo...
