On Descent in Dimension Two and Non-Split Gorenstein Modules (Algebra, Commutative)
… to the same question over normal domains of low dimension (that is, dimension four or less).

Dynamic modeling and analysis of oscillatory bioreactors
… tool for model dynamic analysis, construction of low-dimension model and simple and effective controller design. The validity of a biochemical reactor model often is evaluated by comparing transient responses to experimental data. Dynamic simulation can be rather inefficient and ineffective for …

On Vector Sequence Transforms and Acceleration Techniques
… when we are able to resolve approximations to low dimension invariant subspaces of <em>G</em> which contain large components of the error. When this occurs, simple weighted averages of iterates x,+|, i = 1 ,2 ,... k where k < n are used to produce iterates which contain approximately no error …

The Geometry and Dynamics of Context
… repetitive contexts. We compute the correlation dimension of the space of contexts and show that both visual and semantic context spaces exhibit a two-scaled and low dimensional structure. Finally, we use Takens' delay embedding theorem to show that the low dimension structure is directly related …

Homogenization of Partial Differential Equations with Random, Large Potential
… to a deterministic homogenized PDE in high dimension. The second issue is the convergence of the same equation to a stochastic PDE in low dimension. The third issue is the convergence of elliptic equation with an imaginary potential.

Faster k-means clustering.
… performance of adaptive k-means in medium dimension (20 ≤ d ≤ 200) on uniform random data. Finally, we reformulate the triangle inequality to constrain the search space for a point's nearest center to an annular region centered at the origin. For uniform random data, annulus k-means is …

Projected equation and aggregation-based approximate dynamic programming methods for Tetris
… is some matrix and r is a vector with relatively low dimension. There are two major categories of methods: projected equation methods and aggregation methods. In projected equation methods, the cost-to-go function approximation [phi]r is updated by simulation using one of several policy-updated …

Robust Distributed Stabilization of Interconnected Multiagent Systems
… networks as a few examples. Due to the high-dimension and complexity in configuration of these infrastructures, only a few internal variables of each agent might be measurable and the exact knowledge of the model might be unavailable for the control design purpose. The collective objectives …

Radio resource management techniques for industrial IoT in 5G-and beyond networks
… is a key technology to facilitate Ultra-Reliable Low-Latency Communication (URLLC). Efficient Radio Resource Management (RRM) techniques are necessary to address the challenges posed by interference. The main objective of the research work reported in this thesis is the development of new RRM …

Evolving Network Representation Learning Based on Random Walks
… there is a fast-growing interest in learning low-dimensional continuous representations of networks that can be utilized to perform highly accurate and scalable graph mining tasks. A family of these methods is based on performing random walks on a network to learn its structural features …

Color image quality measures and retrieval
… A novel color correction method applied to low bit-rate JPEG image is developed. A novel method for content-based image retrieval based upon combined feature vectors of shape, texture, and color similarities has been suggested. In addition, an image specific color reduction method has been …

Synthesis and Characterization of Luminescent Nanostructured SiOC Thin Films
… of SiC, C and Si phases. The intense green-yellow luminescence observed in stoichiometric SiOC films caused by the presence of SiC and very low amount of free C. On the other hand, Si rich SiOC film showed a very broad and extremely intense white luminescence peak centred at 620 nm covering …

Efficient solution of the Fokker-Planck Equation via smooth particle hydrodynamics for nonlinear estimation
… and predicting the transient behavior of higher dimensional nonlinear dynamical systems subject to Gaussian white noise excitation remains an open problem with broad application to nonlinear estimation, uncertainty quantification, and reliability to name but a few. These problems remain open in …
