Adaptive sampling and forecasting with mobile sensor networks
… in this combinatorial decision process. This approach computes the reward of each possible sensing choice by propagating the information backwards from the verification time/space to the search space/time. It is shown that this backward method provides an equivalent solution to a standard …

Graph-theoretical consideration in the design of complex engineering systems for robustness and scalability
(cont.) and (2) a forward approach which achieves optimality at the start and grows the system using an optimization technique. We systematically compare the two staging techniques in the context of telescope arrays and evaluate the hypothesis that the backward approach is superior for telescope …

Adjoint Venture: Fast Greeks with Adjoint Algorithmic Differentiation
This dissertation seeks to discuss the adjoint approach to solving affine recursion problems (ARPs) in the context of computing sensitivities of financial instruments. It is shown how, by moving from an intuitive 'forward' approach to solving a recursion to an 'adjoint' approach, one might …

Application of Adjoint Differentiation (AD) for Calculating Libor Market Model Sensitivities
… of financial instruments. The adjoint approach to solving affine recursion problems (ARPs) is presented as a solution to this challenge. A Monte Carlo setting is adopted and it is illustrated how computational efficiency in sensitivity calculation may be significantly improved via the …

Hydrogeology of the Kalahari in north-eastern Namibia
… recharge for the entire catchment was done by a forward approach using satellite images and by an inverse approach using hydrochemical data. From the inverse hydrochemical approach a basin-wide balanced recharge amount of 1.39 mm/a is achieved. The forward approach gave a basin-wide figure of …

Toward an Artifact-Forward Feminist Design History
… allows for testing the efficacy of an artifact-forward research method, Prownian analysis, as a means of studying such objects. Through this case study, I discover the rich potential in highlighting dimmed design histories through subsidizing the more formal, close looking of an artifact-forward …

Design and development of a target-costing model for machining
… this objective. Target costing is a structured approach to determine the cost at which a proposed product, meeting the quality and functionality requirements, must be produced in order to generate the desired profits. It subtracts the desired profit margin from the company's selling price to …

DSM64: A Distributed Shared Memory System in User-Space
… Linux operating systems. I discuss a straight-forward approach to implement SDSM systems in a Linux environment using system-provided tools and concepts avail- able entirely in user-space. I show that the SDSM system presented in this paper is capable of resolving page faults over a local area …

Developing locally relevant applications for rural South Africa : a telemedicine example
… Protocol (VoIP) combined with a store and forward approach for communication. MuTI was tested over a Wireless Fidelity (WiFi) network for several months.

Inverse methods in quantum many-body physics
… phases of matter have been studied using a ""forward"" approach, where a model for the phase is solved to understand the phase's properties. In this thesis, we explore an alternative ""inverse"" approach to the problem, where we find models from properties, and show how inverse methods and …

Towards Advanced Photonic Integrated Systems Through Electronic-Assisted Design
… Since the wavelength of the electrical signals approaches the millimeter region, attention is given to the electromagnetic field distribution, packaging, signal integrity, and noise contributions. This receiver is enabled by the detailed noise analysis, careful modeling of both photonic and …

Dysmorphology Training and Utility in Genetic Counseling
… has shifted the use of dysmorphology from a forward to backward approach. There is no literature describing the continued use of dysmorphology within the genetic counseling field or the training that genetic counseling students receive. The study aims to describe the dysmorphology training …

Space Vector Modulation and Control of Multilevel Converters
… unavoidable neutral point voltage ripple, a feed forward type of control method is developed next. The proposed feed forward algorithm can effectively prevent the neutral point voltage ripple from creating distortions in the converter output voltage under all loading conditions and without causing …

Efficient packet delivery in modern communication networks
… coding. Instead of the traditional store-and-forward approach, network coding allows intermediate nodes in a multi-hop path to code multiple packets into one in order to reduce bandwidth consumption. The coded packet can later be decoded by its recipients to retrieve the original plain packet. …

Probabilistic methods for distributed information dissemination
… Gossip is an alternative to classical flooding approaches: Instead of nodes repeatedly forwarding information to all their neighbors, gossiping nodes forward information only to a small number of (random) neighbors. We show that, when done right, gossip disperses information almost as quickly as …
