In process multi-input multi-output (MIMO) systems are observed that are dominated by interactions between input and outputs. Process decouplers are synthesized to reduce these interactions before controller design. In this work analytical expressions for closed-loop interactive transfer functions are found and interaction reducers (IR) are designed (as process decouplers) for closed-loop contr...

The widespread use of beatand tempo-tracking methods in music information retrieval tasks has been marginalized due to undesirable sporadic results from these algorithms. While sensorimotor and listening studies have demonstrated the subjectivity and variability inherent to human performance of this task, MIR applications such as recommendation require more reliable output than available from p...

Technical efficiency has been widely studied in the literature, but in its pursuit, many of the inputs used can impact on the environment. Environmental effects can be modelled as undesirable output or, as has been the case in more recent studies, as conventional inputs. This paper examines the concept of environmental efficiency and how it can be used to evaluate the performance of Australian ...

Imperfect monitoring of actions in rank-order tournaments makes it possible that undesirable but output-enhancing activities, such as cheating, may occur. Cheating may be especially tempting when one player has an advantage over another. We show that when audit probabilities are low, the leading player has more incentive to cheat; when audit probabilities are high, the incentive is reversed. Fu...

We propose an unsupervised bootstrapping method to generate a new type of affect knowledge base: the sentiment expectation of nouns (e.g., “high salary” is desirable while “high price” is usually undesirable, because people have opposite sentiment expectation towards “salary” and “price”). A bootstrapping framework is designed to retrieve patterns that might be used to express complaints from t...

In many cases, optimal operation for a plant is the same as maximum throughput. In this case a rigorous model for the plant is not necessary if we are able to identify the bottleneck. Optimal operation is the same as maximum throughput in the bottleneck. If the bottleneck does not move, this can be realized with singleloop controller from the throughput manipulator to the bottleneck. However, i...

Policy-gradient approaches to reinforcement learning have two common and undesirable overhead procedures, namely warm-start training and sample variance reduction. In this paper, we describe a reinforcement learning method based on a softmax value function that requires neither of these procedures. Our method combines the advantages of policy-gradient methods with the efficiency and simplicity ...

This article proposes a model for evaluating inefficiency accounting firms’ corporate social responsibility engagement as part of their broader output production activities. The combines the marketable outputs, socially responsible and undesirable outputs into overall measures firm performance using data envelopment approaches. Methodologically, builds on dynamic by-production model, which acco...

We investigate the origin of undesirable transverse cracks often observed in thin films obtained by the layer transfer technique. During this process, two crystals bonded to each other containing a weak plan produced by ion implantation are heated to let a thin layer of one of the material on the other. The level of stress imposed on the film during the heating phase due to the mismatch of ther...

The input data for DNA computing must be encoded into the form of single or double DNA strands. As complementary parts of single strands can bind together forming a double-stranded DNA sequence, one has to impose restrictions on these sets of DNA words (=languages) to prevent them from interacting in undesirable ways. We recall a list of known properties of DNA languages which are free of certa...
