Robust GM Wiener Filter in the Complex Domain
… a STAP radar processing system based on Adaptive Complex Projection Statistics has been proposed and successfully"filters out the noise condition even when outliers are present. However, this algorithm requires the data to be entirely real. Radar data, which consists of amplitude and phase, is …

High-Order and Wavelet-Adaptive Immersed Methods for PDEs on Complex Domain Geometries
… transform algorithm applicable to computational domains with arbitrary geometries. This wavelet transform maintains the order of the wavelet and serves as an indicator for local truncation error (LTE), resulting in an adaptive resolution strategy with explicit error control. To address the …

Solving planning problems with deep reinforcement learning and tree search
… learning methods are capable of learning complex heuristics starting with no prior knowledge, but struggle in environments where the learning signal is sparse. In contrast, planning methods can discover the optimal path to a goal in the absence of external rewards, but often require a …

Modeling phonon-polariton generation and control in ferroelectric crystals
… demonstrates considerable improvement in complex domain by achieving varied accuracy over space based on the level of interest of the region, which may facilitate scientific exploration in high power terahertz generation and polaritonic signal processing.

The application of natural language processing to open source intelligence for ontology development in the advanced persistent threat domain
… to build an open source Ontology in the APT domain with the goal of building a dictionary and taxonomy for this complex domain.</p>

Developing Bottom-Up, Integrated Omics Methodologies for Big Data Biomarker Discovery
… (GWAS) datasets. These data sets are often complex, poorly annotated or require complex domain knowledge to sensibly manage. These novel datasets provide a rare, multi-dimensional omics (proteomics, transcriptomics, and genomics) view of a single sample or patient. Previously, biologists …

Wave Propagation Problems in Certain Elastic Anisotropic Half Spaces
… The mapping of the wave fields in the complex domain composed of a four-sheeted Riemann surface is examined in detail. Some of the techniques used in the numerical treatment of certain singularities are briefly discussed. The numerical results are given in the form of time histories for …

Closability of differential operators and subjordan operators
… with compact support on the real line, and the domain of D is taken to be the polynomials. Approximation questions more general than what is needed for the operator theory result are also discussed. Specifically, an explicit characterization of the closure of the graph of D for a large class of …

Plausible Inference: A Knowledge-Intensive Approach to Induction (An Application of PI to the Problem of Hidden Homology Modeling)
… as a user-controlled tool that assists in complex domain modeling. Using this perspective we develop Plausible Inference (PI)--a framework based on the tradeoffs suggested by this learning-as-a-tool perspective. Four aspects of the approach distinguish it from other learning approaches, and …

Exploration of Sensemaking in the Education of Novices to the Complex Cognitive Work Domain of Air Traffic Control
<p>Many current complex business and industry jobs consist primarily of cognitive work; however, current approaches to training may be inadequate for this type of work (Hoffman, Feltovich, Fiore, Klein, & Ziebell, 2009). To try and improve training and education for cognitive work, Klein and Baxter …

A Unified Overlapping Finite Element Formulation
… obtaining an adequate mesh for a geometrically complex analysis domain is still challenging in traditional finite element analysis since the elements can be severely geometrically distorted and thus perform poorly. The AMORE meshing scheme and the overlapping finite elements have been recently …

Wavelets Based on Second Order Linear Time Invariant Systems, Theory and Applications
… second is a generalization of the first to the complex domain and is similar to the Laplace transform kernel function. The first takes the acronym of SOULTI wavelet, while the second is named the Laplace wavelet. The most important criteria for a function or signal to be a wavelet is the ability …

A dynamic visual analytics framework for complex temporal environments
… data streams. An overabundance of information in complex environments have been attributed to information overload, a state of exposure to overwhelming and excessive information. The use of visual analytics provides leverage over potential information overload challenges. Apart from automated …

Tracking and modelling of team game interactions
… rapidly changing, and frequently occluded domains (for example a soccer pitch) is a complex problem, particularly given the non-linear nature of each player's movements. This thesis presents a stochastic sampling based multiple object tracker, capable of tracking objects from a single …

IT Consumerization & Enterprise Architecture: An Exploratory Case Study
… research suggest that IT Consumerization is a complex domain characterized with unpredictability, unknown decision variables, and no single correct answer in the context of problem solving and decision making. Our research suggests that in order for an EA practice to help in IT Consumerization …

Exploiting quasiperiodic electromagnetic radiation using software-defined radio
… very poor. Coherent periodic averaging in the complex domain can suppress noise and uncorrelated background sources. I design a phase-locked loop to perform clock recovery and synchronisation of the video signal, negating the effects of temperature drift in the local oscillators. This permits …

The Functional Contributions of Consciousness
… processing in different psychological domains, namely, vision, emotion, and social cognition. I also defend the principle of functional pluralism: given that conscious experiences presumably form a relatively diverse class in the natural world, we should expect them to facilitate a …

A Pattern-Based Approach to Changing Software Requirements in Brown-Field Business Contexts
… processes. 'Socio-technical' refers to the complex systems of people, tasks and technology. Supporting this alignment is exacerbated by the speed of technological change and its relationship with organisation growth. This complexity is further aggravated in a number of ways. Organisations …
