Multiple feed reflector antenna analysis
… to determine the incident field via a coordinate transformation approach. The incident field from each element is superimposed to form the total field used in finding the surface currents of the physical optics radiation integral. The technique allows each element to be arbitrarily excited, …

Interdepdence Of Community Mental Health Care Providers In An Urban County: A Spatial Panel Approach
… with individual effects and other controls. A transformation approach is applied to ensure consistency of the estimates. Results support some degree of interdependence between neighboring sites/clinics and time dynamics in terms of their gross revenue. The study also provides other implications …

The required ansatz to construct Lie point transformations and the symmetries of a first-order stochastic differential equation
… the required ansatz to determine Lie point transformations of evolution-type equations from the contact transformation approach. We indicate that the Lie point transformations of the Fokker-Planck equation (FPE), which is a second-order linear parabolic partial differential equation (PDE), …

Automating The Detection and Resolution of Build Conflicts in Software Merge for Java Programs
… and implemented a graph-based pattern matching approach, BUCOND (Build Conflict Detector), to detect conflicts via static analysis. Our evaluation shows that BUCOND accurately identified build conflicts on both synthetic and real-world datasets; it demonstrated great applicability in scenarios …

Many-body entanglement : topological orders, tensor networks and superconductivity
… wave functions, obtained in the string-net approach by Levin and Wen and the local unitary transformation approach by Chen, Gu and Wen. In doing so, (S, T)-matrices act as our non-local "order parameter" and give a full characterization of 2+ 1D exact topological orders (topological orders …

Modeling of acoustic-emission wave propagation in layered media
… layer is solved with the use of an integral transformation approach. The 3D wave motions are decomposed into 2D wave motion with coupled P-SV waves and 1D with SH waves in a transformed, frequency-wavenumber domain, where P and S indicate respectively compression and shear waves, SH denotes a …

Organizational assessment processes for enterprise transformation
Enterprise transformation is a dynamic process that builds upon and affects organizational processes. Organizational assessment plays critical role in planning and execution of enterprise transformation. It allows the assessment of an enterprise's current capabilities as well as for identification …

Case reuse in textual case-based reasoning.
… textual solution. Thereafter, compositional and transformational approaches to text reuse are introduced to address the question of how to reuse textual solutions. The main idea in the compositional approach is to generate a textual solution by using prototypical sentences across similar authors. …
