Conditionally convergent vector series
In this paper we propose to study the behavior of series of complex numbers, or of vectors in two dimensions; and to generalize this study to the case of vectors in n dimensions. The particular properties to be studied are described on page 7. We shall firsts state a few well-known properties of …

Semantic unification for convergent systems
Equation solving is the process of finding a substitution of terms for variables that makes two terms equal in a given theory, while semantic unification is the process that generates a basis set of such unifying substitutions. A simpler variant of the problem is semantic matching, where the …

Convergent evolution of betalains in Caryophyllales
… that allows for the possibility of repeated convergent shifts from anthocyanin to betalain pigmentation. First, I begin by framing my thesis with a review of the concepts of convergence and parallelism, including the connection between these terms and concepts of adaptation and constraint. I …

Ontogeny within a convergent evolutionary context
… morphologies are entirely novel, and focus on convergent morphologies (e.g., longirostry, limblessness, wings) provide a unique opportunity to investigate the micro- and macroevolutionary processes that drive disparity and diversification. Convergent evolution currently is hypothesized to occur …

Design and application of convergent cellular automata
Systems made of many interacting elements may display unanticipated emergent properties. A system for which the desired properties are the same as those which emerge will be inherently robust. Currently available techniques for designing emergent properties are prohibitively costly for all but the …

Inclusion behaviour in steel flows through convergent nozzles.
<p>It is well established that nozzle blockage in Al-killed continuously cast steels is caused by the deposition of preexisting Al 0 inclusions at the narrowest part of the nozzle. Thisa adhere strongly at the wall by interfacial forces. The theory examined in this thesis is that during the curved …

Innovating for survival in a convergent newsroom environment
… a leading role in managing the transition to a convergent newsroom at the Lancashire Evening Post, a regional newspaper in Lancashire. The innovative content produced by the author, and the new editorial processes which he and fellow managers implemented, are critically analysed through the …

Toward a Convergent Evidence-Based Urban Design Approach
… and their concerns, and ultimately argue that a convergent method is necessary. The conceptual framework I develop is one that responds to concerns of equity and accountability in the built environment, while also maintaining the significance of good design and acknowledging the inevitable …

Designing Provably Convergent Algorithms from the Geometry of Data
… structure is then used to derive a provably convergent dataset distillation technique, which finds a small training set that maximises performance after training. These algorithms are derived using techniques from Monte Carlo methods, Wasserstein metrics, optimal quantisation, and diffusion …

Melt generation in the Earth's mantle at Convergent Plate Margins
… low temperatures in the mantle wedge at convergent plate margins in the presence of excess H²O or following the breakdown of the hydrous mineral chlorite. A new petrologic model that simulates anhydrous melting of variably metasomatized upper mantle is developed to investigate the …

Innovative practice in the building process : a convergent development approach
… estate development and architectural design, the Convergent Model, which seeks to simplify the building process and align economic, social, and cultural goals within a truly interdisciplinary team of professionals. The process is a potential solution to the compounded and interconnected issues of …

The mechanisms underlying convergent evolution in the plumage patterns of birds
Convergent evolution is a central theme in biology. Birds are an ideal system to examine the mechanisms underlying convergent evolution. Although bird patterning is diverse, within-feather patterns have repeatedly converged on the same four types: mottled patterns, scales, bars and spots. Other …

Understanding Convergent Innovation in Healthcare Technologies: Relational Models for Nascent Ecosystems
… areas in healthcare technology, underpinned by 'convergent technology' or 'cross-industry' innovation. However, convergence results in greater uncertainty and influence from new knowledge and actors, including previously disparate technologies and capabilities, bringing specific challenges in the …

Elucidation of bipolar disorder : a convergent approach using genetics and imaging
The aims were to determine whether variants, within ten selected candidate genes, have an association with BPD and whether any relationship exists between these variants and brain imaging volumes in subjects with BPD. The objectives were to i) select a list of BPD candidate genes, ii) identify a …
