Comparison of plant-wide oscillation detection methods
Plant-wide oscillations are common in many industrial processes. During the past few years, various methods have been proposed for the detection of plant-wide oscillations, including methods based on the autocorrelation ...
Primes in quadratic progressions on average
In this paper, we establish a theorem on the distribution of primes in quadratic progressions on average.
Level set method for positron emission tomography
In positron emission tomography (PET), a radioactive compound is injected into the body to promote a tissue-dependent emission rate. Expectation maximization (EM) reconstruction algorithms are iterative techniques which ...
L1/Q approach for efficient computation of disturbance rejection measures for feedback control
This paper presents practical methods for computation of disturbance rejection measures, which are useful for assessing the dynamic operability of the process. Using L1 optimal control theory, we consider the cases ...
Neurotrophins : more than Neurotrophic
The Nerve Growth Factor (NGF) is the prototypic member of the neurotrophin (NT) family, which plays an essential role in the development and functioning of the vertebrate nervous system. Although originally defined by their ...
Kagome antiferromagnet : a Schwinger-boson mean-field theory study
The Heisenberg antiferromagnet on the kagome lattice is studied in the framework of Schwinger-boson mean-field theory. Two solutions with different symmetries are presented. One solution gives ...
On extremal k-graphs without repeated copies of 2-intersecting edges
The problem of determining extremal hypergraphs containing at most r isomorphic copies of some element of a given hypergraph family was first studied by Boros et al. in 2001. There are not many hypergraph families for which ...
A nonlinear multigrid method for total variation minimization from image restoration
Image restoration has been an active research topic and variational formulations are particularly effective in high quality recovery. Although there exist many modelling and theoretical results, available iterative solvers ...
Hybrid inorganic/organic microstructured light-emitting diodes produced using photocurable polymer blends
Light-emitting diodes LEDs in the form of a one-dimensional array of microstripes emitting at 370 nm were fabricated from AlInGaN inorganic semiconductor. These microlight sources were then used to “directly write” ...
The PBD-closure of constant-composition codes
We show an interesting pairwise balanced design (PBD)-closure result for the set of lengths of constant-composition codes whose distance and size meet certain conditions. A consequence of this PBD-closure result is that ...
