Linear and log-linear models based on generalized inverse sampling scheme
… modeling rare events using generalized inverse sampling scheme. The Poisson model can be used for independent frequency count data. Also negative binomial and negative multinomial (NMn) models are applicable when there is only one rare category in the population. Here, a new model, based on …

A novel technique for phased array receivers based on an economic sampling scheme
… a novel phased receiver, based on an economic sampling scheme is proposed. All the elements in an array receive a common information (signal amplitude) and a unique information (relative delay between elements). The idea is to sample only the information required to reconstruct the transmitted …

High voltage sampling scheme independent of capacitor voltage coefficient for a delta sigma modulator
… battery packs. This paper presents a unique sampling scheme for a delta sigma modulator that is independent of common mode voltage. The rejection of common mode voltage is important in the application of electric vehicles and other large battery packs in order to accurately measure every cell …

Cross product ratio under different sampling schemes and zero truncated negative binomial weighted Weibull distribution with applications
… Bernoulli samples and determine the best sampling scheme. The idea of using Bernoulli samples to conduct clinical trials has been very successful since it is cost effective. Bias and Mean Squared Errors are used as the principal criteria. According to the simulation results, the special …

Sequential Sampling Designs for Estimating Software Reliability
… during testing is a shortcoming of a fixed sampling scheme. We applied sequential sampling schemes to make allocation decisions dynamically throughout the testing process. Under these sampling schemes, we can refine the allocation of test cases sequentially based on the information gained as …

Sequential Designs with Application in Software Engineering
… process. We started with a fully sequential sampling scheme to estimate the reliability of a software system using partition testing. We have shown both theoretically and through simulation that the proposed scheme always performs at least as well as fixed sampling approaches where test case …

A sampling technique based on LDPC codes
… Monte Carlo methods, which rely on repeated sampling of the target distribution to obtain numerical results, is a powerful and popular way to tackle difficult inference problems. In order to use Monte Carlo methods, a good sampling scheme is vital. This thesis aims to propose a new sampling …

Robust Content Identification and De-Duplication with Scalable Fisher Vector In video with Temporal Sampling
… In this work, we propose a scalable hashing scheme based Fisher Vector aggregation of selected key point features, and a frame significance function based non-uniform temporal sampling scheme on the video segments, to create a very compact binary representation of the content fragments that …

Motor Imagery Based Brain Computer Interfaces
… sampled hyper-sphere. A novel non-uniform sampling scheme is proposed to estimate the local mean of multivariate signals. The non-uniform samples are generated by linearly transforming the hypersphere into an N dimensional ellipsoid using singular value decomposition (SVD). A number of …

Design and implementation of A truecolor wide dimming single-pin LED driver
… experimental data show that the low-side current sampling scheme is able to work with the least number of pins with acceptable accuracy.

The development and application of statistical sampling regime to map out hydrocarbons in sediments.
… investigates and develops a stratified random sampling design for sediments in an offshore oil field environment. The sampling area was partitioned equally into sixteen zones. Stratification was based on the near-field and far-field areas, and the number of samples in each zone was chosen by …

Network reliability estimation
… reliability estimation. There are two main sampling techniques in reliability estimation: combinatorial and permutational sampling. Combinatorial sampling has the advantage of speed but has poor performance in rare event simulations. Permutational sampling gives good simulation performance …

Hybrid adaptive sequential sampling for reliability-based design optimization
… In this thesis, a new hybrid adaptive sequential sampling strategy has been developed to substantially improve the efficiency of the surrogate model development process. The developed sampling strategy combines local sampling that focuses on regional model fidelity improvements with global …

Bayesian analysis for categorical survey data
… unknown design variables taking into account the sampling scheme. Random effects are incorporated in the model to deal with the effect of sampling design, that produces the Multinomial GLMM and issues such as model comparison and model averaging are also discussed. The methodology is applied in a …

Hybrid Micro/nanofluidic Sampling Schemes for Mass Spectrometry
Novel analytical sampling techniques are investigated in an effort to advance the exploration of chemical reactions underlying life processes. The analysis of substances found in living organisms is challenging and includes the precise collection, preparation, and identification of complex …

Compiling Fast Partial Derivatives of Functions Given by Algorithms
… will use numerical differencing. This is a sampling scheme that approximates derivatives by the slope of secants in closely spaced points. Symbolic methods that make full use of the program text of Af should be able to come up with a better way to evaluate the gradient of f. The system …
