The origin and evolution of urban form in Wanganui East, Gonville and Castlecliff : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Geography at Massey University
The decision to study the urban form of Wanganui East, Gonville and Castlecliff (Plates 1,2 and 3) was made in 1968 after discussions with Mr. Ross, the then Town Planner for the City of Wanganui. Tho topic was chosen for two reasons. It was felt that the results could provide an insight into the evolution and nuture of the suburbs concerned, which would be of use to the City Planners. In addition it allowed for study in depth of concepts which appeared to be of considerable relevance not only to the geographer, but to the community as a whole. The three suburbs were selected because they alone within the present Borough of Wanganui had once existed as separate towns (see AppendixA), and it was thought that because of this they might exhibit distinctive characteristics in their physical form. This hypothesis appeared to be supported by a preliminary investigation of the material available. Concomitant with this assumption and resultant hypothesis was the belief that it was in any case important to examine and identify the elements of form in urban areas. It was felt that these, if investigated properly, could be helpful in correcting some of the problems inherent in the suburbs, and in New Zealand towns in general
Endoscopic transfer of orbital integrals in large residual characteristic
This article constructs Shalika germs in the context of motivic integration,
both for ordinary orbital integrals and kappa-orbital integrals. Based on
transfer principles in motivic integration and on Waldspurger's endoscopic
transfer of smooth functions in characteristic zero, we deduce the endoscopic
transfer of smooth functions in sufficiently large residual characteristic.Comment: 33 page
A Domain Specific Approach to High Performance Heterogeneous Computing
Users of heterogeneous computing systems face two problems: firstly, in
understanding the trade-off relationships between the observable
characteristics of their applications, such as latency and quality of the
result, and secondly, how to exploit knowledge of these characteristics to
allocate work to distributed computing platforms efficiently. A domain specific
approach addresses both of these problems. By considering a subset of
operations or functions, models of the observable characteristics or domain
metrics may be formulated in advance, and populated at run-time for task
instances. These metric models can then be used to express the allocation of
work as a constrained integer program, which can be solved using heuristics,
machine learning or Mixed Integer Linear Programming (MILP) frameworks. These
claims are illustrated using the example domain of derivatives pricing in
computational finance, with the domain metrics of workload latency or makespan
and pricing accuracy. For a large, varied workload of 128 Black-Scholes and
Heston model-based option pricing tasks, running upon a diverse array of 16
Multicore CPUs, GPUs and FPGAs platforms, predictions made by models of both
the makespan and accuracy are generally within 10% of the run-time performance.
When these models are used as inputs to machine learning and MILP-based
workload allocation approaches, a latency improvement of up to 24 and 270 times
over the heuristic approach is seen.Comment: 14 pages, preprint draft, minor revisio
Seeing Shapes in Clouds: On the Performance-Cost trade-off for Heterogeneous Infrastructure-as-a-Service
In the near future FPGAs will be available by the hour, however this new
Infrastructure as a Service (IaaS) usage mode presents both an opportunity and
a challenge: The opportunity is that programmers can potentially trade
resources for performance on a much larger scale, for much shorter periods of
time than before. The challenge is in finding and traversing the trade-off for
heterogeneous IaaS that guarantees increased resources result in the greatest
possible increased performance. Such a trade-off is Pareto optimal. The Pareto
optimal trade-off for clusters of heterogeneous resources can be found by
solving multiple, multi-objective optimisation problems, resulting in an
optimal allocation of tasks to the available platforms. Solving these
optimisation programs can be done using simple heuristic approaches or formal
Mixed Integer Linear Programming (MILP) techniques. When pricing 128 financial
options using a Monte Carlo algorithm upon a heterogeneous cluster of Multicore
CPU, GPU and FPGA platforms, the MILP approach produces a trade-off that is up
to 110% faster than a heuristic approach, and over 50% cheaper. These results
suggest that high quality performance-resource trade-offs of heterogeneous IaaS
are best realised through a formal optimisation approach.Comment: Presented at Second International Workshop on FPGAs for Software

Income Inequality, Cohesiveness and Commonality in the Euro Area: A Semi-Parametric Boundary-Free Analysis
The cohesiveness of constituent nations in a confederation such as the Eurozone depends on their equally shared experiences. In terms of household incomes, commonality of distribution across those constituent nations with that of the Eurozone as an entity in itself is of the essence. Generally, income classification has proceeded by employing âhardâ, somewhat arbitrary and contentious boundaries. Here, in an analysis of Eurozone household income distributions over the period 2006â2015, mixture distribution techniques are used to determine the number and size of groups or classes endogenously without resort to such hard boundaries. In so doing, some new indices of polarization, segmentation and commonality of distribution are developed in the context of a decomposition of the Gini coefficient and the roles of, and relationships between, these groups in societal income inequality, poverty, polarization and societal segmentation are examined. What emerges for the Eurozone as an entity is a four-class, increasingly unequal polarizing structure with income growth in all four classes. With regard to individual constituent nation class membership, some advanced, some fell back, with most exhibiting significant polarizing behaviour. However, in the face of increasing overall Eurozone inequality, constituent nations were becoming increasingly similar in distribution, which can be construed as characteristic of a more cohesive society
Followership: Why Leadership Works
Using the theory of followership developed by Robert Kelley, this case study will examine the role of the follower, the various types of followers present in organizations and their importance to the study of leadership. lt will examine an alternative theory by lra Chaleff and discuss current literature on the follower-leader relationship. This case study will then examine the followership skills of Agnes Anderson (name changed), through analysis of her followership self-assessment and the followership assessments completed by leaders she has worked with in both professional and volunteer situations and conclude with general observations on the topic
