Complex exponential smoothing
Exponential smoothing is one of the most popular forecasting methods in practice. It has been used and researched for more than half a century. It started as an ad-hoc forecasting method and developed to a family of state-space models. Still all exponential smoothing methods are based on time …

Fuzzy Filters for depth map smoothing
… acting fuzzy filter is applied to the task of smoothing a disparity map. The first order Sugeno fuzzy system is then proposed as an architecture that would be suitable as the basis for a direct acting fuzzy filter. This architecture is then applied to the task of smoothing depth maps derived …

CODE SMOOTHING, UNIFORM DISTRIBUTIONS, AND APPLICATIONS
… The central technique used in this study is code smoothing, which involves applying additive noise to a uniformly random codeword, producing an output distribution that closely approximates uniformity. We characterize the code rate thresholds required to achieve strong uniformity guarantees, …

Nonparametric smoothing in extreme value theory
… to the underlying data by simply changing the smoothing parameter. To evaluate the overall performance of the extreme value theory methodology in smoothing extremes a simulation study was performed.

Income smoothing: An asymmetric information approach
… with private information engage in income smoothing and to provide new insights into income smoothing. In particular, this study extends the existing income smoothing literature by highlighting informational properties of income smoothing. Using comparative statics, this thesis also …

Smoothing estimates for non commutative spaces
"In the first part of this thesis, we follow Varopoulos's perspective to establish the noncommutaive Sobolev inequaties (namely, Hardy-Littlewood-Sobolev inequalites), and extend the Sobolev embedding from noncommutative $L_p$ spaces to general Orlicz function spaces related with Cowling and Meda's …

Smoothing silver nanowires for optoelectronic applications
Silver nanowire meshes have shown potential for becoming a more robust, flexible alternative to traditional ceramic and brittle metal oxides. However, the current methods employed at making these films are not scalable and the high aspect ratios limit their final use. Spray coating is a technique …

Bias Assessment and Reduction in Kernel Smoothing
… local polynomial regression (LPR) with kernel smoothing, the choice of the smoothing parameter, or bandwidth, is critical. The performance of the method is often evaluated using the Mean Square Error (MSE). Bias and variance are two components of MSE. Kernel methods are known to exhibit varying …

Smoothing PV output fluctuation using cooling fan
Due to the growth of solar power and the concern regarding its effects on power system because of its intermittency and zero inertia, in this project I am trying to smooth solar power using electrical consumer. The purpose of this project is to absorb PV output fluctuation as much as possible with …

Smoothing Parameter Selection In Nonparametric Functional Estimation
… to obtain completely data-driven choices of the smoothing parameter in functional estimation, within the confines of minimal assumptions. The focus of the study will be within the framework of the estimation of the distribution function, the density function and their multivariable extensions …

Taxation and income smoothing: Evidence from accruals
… the effects of taxation on managers' income smoothing activities. Risk-averse managers are motivated to reduce the variability of accounting earnings when their compensation heavily depends on such earnings. Taxation enters into managers' income smoothing decisions in two ways. First, the tax …

Human-automation collaboration in occluded trajectory smoothing
Deciding if and what objects should be engaged in a Ballistic Missile Defense System (BMDS) scenario involves a number of complex issues. The system is large and the timelines may be on the order of a few minutes, which drives designers to highly automate these systems. On the other hand, the …

Feature preserving smoothing of 3D surface scans
… devices. This thesis presents new methods for smoothing scanned data, based on extensions of the bilateral filter to 3D. The bilateral filter is a non-linear, edge-preserving image filter; its extension to 3D leads to an efficient, feature preserving filter for a wide class of surface …

On robust corner-preserving smoothing in image processing
This Ph.D. thesis treats consistency, robustness and dicontinuity-preserving issues of M-kernel estimators in one- and two-dimensional regression. The M-kernel smoother was first introduced by Härdle and Gasser (1984) who provide a restricted valid proof of consistency for a monotone score function …

Topics in interpolation and smoothing of spatial data
… of special topics in spatial interpolation and smoothing. The motivation for the thesis comes from two projects, one being to extend the availability of a daily rainfall model for southern Africa to sites at which little or no rainfall data is available, using data from nearby sites, and the …
