Evaporation-driven, Template-assisted Nanocrystal Assembly (ETNA): A Novel Approach to Fabrication of Functional Nanocrystal Solids

Ghadimi, Arya 24 February 2009 (has links)
Synthesis of nanocrystals is one of the most rapidly advancing areas of nanoscience, and today nanocrystals can be produced with impressive control over their composition, size, shape, polydispersity, and surface chemistry. As such, they are ideal building blocks for fabricating hierarchical architectures with tailorable functionality on every level of the hierarchy. Here an evaporation-driven, template-assisted nanocrystal assembly (ETNA) technique is developed, providing a novel and general approach to fabricating freestanding, 3D, functional architectures using diverse combinations of colloidal nanocrystal species and porous templates of arbitrary geometry. Colloidal PbS (photoluminescent) and CoFe2O4 (superparamagnetic) nanocrystals are template-assembled to fabricate freestanding nanorods and inverse opals, which retain the size-dependent properties of their constituent building blocks while replicating the geometry and preserving the functionality of the templates. Further multifunctionality is demonstrated through mixed-nanocrystal architectures which exhibit the aggregate functionality of their building blocks.

Timing Aware Partitioning for Multi-FPGA based Logic Simulation using Top-down Selective Flattening

Poothamkurissi Swaminathan, Subramanian 2012 August 1900 (has links)
In order to accelerate logic simulation, it is highly beneficial to simulate the circuit design on FPGA hardware. However, limited hardware resources on FPGAs prevent large designs from being implemented on a single FPGA. Hence there is a need to partition the design and simulate it on a multi-FPGA platform. In contrast to existing FPGA-based post-synthesis partitioning approaches which first completely flatten the circuit and then possibly perform bottom-up clustering, we perform a selective top-down flattening and thereby avoid the potential netlist blowup. This also allows us to preserve the design hierarchy to guide the partitioning and to make subsequent debugging easier. Our approach analyzes the hierarchical design and selectively flattens instances using two metrics based on slack. The resulting partially flattened netlist is converted to a hypergraph, partitioned using a public domain partitioner (hMetis), and reconverted back to a plurality of FPGA netlists, one for each FPGA of the FPGA-based accelerated logic simulation platform. We compare our approach with a partitioning approach that operates on a completely flattened netlist. Static timing analysis was performed for both approaches, and over 15 examples from the OpenCores project, our approach yields a 52% logic simulation speedup and about 0.74x runtime for the entire flow, compared to the completely flat approach. The entire tool chain of our approach is automated in an end-to-end flow from hierarchy extraction, selective flattening, partitioning, and netlist reconstruction. Compared to an existing method which also performs slack-based partitioning of a hierarchical netlist, we obtain a 35% simulation speedup.

The Firm Size Effect: An Application of Hierarchy Theories

Wilson, Hugh David, Economics, Australian School of Business, UNSW January 2000 (has links)
In this thesis the positive relationship between firm size and wages is investigated through the application of hierarchy theories. Many different explanations have been proposed for this relationship, but have met only limited success at best. The strongest finding to date is that unobserved ability is a significant factor. The question of interest here is ???why do wages increase as the size firm increases???? Hierarchy theories take a different approach towards the analysis of firms in comparison to the alternate theories which have dominated previous investigations. As a result of their focus on the organisational relationships within a firm???s internal structure, hierarchy theories offer certain insights to the size-wage relationship which to date have been unnoticed. An empirical investigation into the size-wage differential incorporating structural considerations into an augmented wage equation offers strong support for the propositions of hierarchy theories. I find that half of the firm size effect for workers can be explained by controlling for some aspects of management structure, and that span of control has a discontinuous effect on wages. These results are completely consistent with the existing findings on unobserved ability and have the added attraction of providing economic as well as statistical explanatory power.

Power relationships within a corporate finance department: a Foucauldian approach to corporate hierarchies and resistance

Garland, Angela M Unknown Date (has links)
This PhD thesis investigates power relationships within a corporate Finance Department employing a Foucauldian approach to explaining corporate hierarchies and resistance and the implications.Research was conducted in the form of a case study and observation of a corporate finance department, referred to as the 'Finance Department', at the 'Company', referred to as such for confidentiality purposes. The Company is a large Dutch based mail and logistics entity that operates internationally across over 200 countries and has its corporate head office just outside of Amsterdam. The Company's Finance Department was in the throws of change, particularly around hierarchies as a result of the reengineering process with the purpose of creating efficiencies. The aim of the research was to evaluate the power relationships that existed within the hierarchies between management and workers who worked either for the Finance Department or closely with it, and to analyse the outcomes of these power relationships in terms of resistance.The case study is a Foucauldian insight into the different individuals who worked either within the Finance Department or closely with it, with an evaluation of their roles and how their differing power structures impacted upon the workflow within the Finance Department.The outcome of this research is an evaluation of those individuals and their relationships at a particular point in time, which was impacted by so many different factors. The research could give readers an understanding of power relationships and framework for contextual Foucauldian evaluation.The significance of the contribution arising from this particular piece of research is that it involves the combination of a case study method with a Foucauldian perspective. The combination of these two elements allows the research to be done both from the top down and also from the bottom up. Increasing in use as a research tool (Hamel, 1992), the case study contributes uniquely to our body of knowledge of individual, organisational, social and political phenomena (Yin, 1994). The Foucauldian perspective plays an important part in terms of an understanding of power, despite the fact that it is often difficult to fully comprehend the meanings behind Foucault's work (McHoul & Grace, 1993).
