Mutually Unbiased Bases in Low Dimensions
… exist if it is possible to identify d mutually unbiased (MU) complex (d×d) Hadamard matrices, defining a complete set of d+1 MU bases. This thesis is an exploration of sets of r≤d+1 MU bases in low dimensions. We derive all inequivalent sets of MU bases in dimensions two to five confirming that …

Best Linear Unbiased Estimation Fusion with Constraints
… to the above topics by applying the best linear unbiased estimation (BLUE) fusion. We propose optimal data compression by reducing sensor data from a higher dimension to a lower dimension with minimal or no performance loss at the fusion center. For single-sensor and some particular …

An analytic representation of weak mutually unbiased bases
… Hilbert space are considered. The mutually unbiased bases is a deep problem in this area. The problem of finding all mutually unbiased bases for higher (non-prime) dimension is still open. We derive an alternate approach to mutually unbiased bases by studying a weaker concept which we call …

Efficient Unbiased Estimating Equations for Analyzing Structured Correlation Matrices
… very successful to estimate the correlations and unbiased estimating equation approach has become a popular alternative when there may be a departure from normality. In this thesis we show that the optimal unbiased estimating equation coincides with the likelihood equations for normal data. We …

Unbiased Filtered Rayleigh Scattering Measurement Model for Aerodynamic Flows
The filtered Rayleigh scattering (FRS) optical diagnostic has become an attractive technique for advanced aerodynamic measurements. The appeal of FRS is that it can simultaneously quantify density, temperature, and vector velocity. Additionally, it is entirely non-intrusive to the flow since the …

Active learning in recommender systems: an unbiased and beyond-accuracy perspective
… a biased dataset to generate a new dataset with unbiased-like properties. Compared to the most similar approach proposed in the literature, we give empirical evidence, using two publicly-available datasets, that WTD and WTD_H are more effective at debiasing the evaluation of different recommender …

Partial ordering of weak mutually unbiased bases in finite quantum systems
… with variables in Zd, especially on mutually unbiased bases. The reason for this is due to its wide areas of application. We focus on partial ordering of weak mutually un-biased bases. In it, we studied a partial ordered relation which exists between a subsystem ^(q) and a larger system ^(d) …

An unbiased proteomic approach to identifying cell surface markers in neutrophils
Introduction: Efferocytosis refers to the engulfment of dead cells by phagocytes such as neutrophils and macrophages and culminates in the beneficial removal of inflammatory cargo and auto-reactive material. While many of the mechanisms involved in efferocytosis have been described, the critically …

Lower bounds for the variance of uniformly minimum variance unbiased estimators
… ·for the variance of uniformly minimum variance unbiased estimators. The lower bounds of Cramer and Rao, Bhattacharyya, Hammersley, Chapman and Robbins, and Kiefer were derived and discussed. Each was compared with the other, showing their relative merits and shortcomings. Of the lower bounds …

Dissecting Host-Viral Interactons Through Focused or Unbiased High-Throughput Genetic Approaches
<p>In the world around us, viruses surround and vastly outnumber us. Indeed, there are roughly 1 sextillion—or one thousand million million million—times as many viral particles as humans on earth (1). While most of these viruses do not cause disease in humans, those that do present a grave and …

AN UNBIASED SOURCE LOCATION ALGORITHM AND PERFORMANCE SURFACE OF ZERO TRACKING ALGORITHMS
… the locations of directional sources in an unbiased manner is presented. The zeros of the system, which correspond to the sources' locations, are updated recursively taking into account the effect of receiver noise. A formula relating the variances of the sources' locations to the number of …

An unbiased infrared H2 search for embedded flows from young stars in Orion A
Gasausströmungen, oft in der Form hoch kollimierter Jets, sind ein allgegenwärtiges Phänomen bei der Geburt neuer Sterne. Emission von stossangeregtem molekularem Wasserstoff bei Wellenlängen im nahen Infrarotbereich ist ein Merkmal ihrer Existenz und auch in eingebetteten, im Optischen …

Comparison of Bayes' and minimum variance unbiased estimators of reliability in the extreme value life testing model
… as the life-testing model. First the unbiased minimum variance estimator is derived. Then the Bayes' estimators for the uniform, exponential, and inverted gamma prior distributions are obtained, and these results are extended to a whole class of exponential failure models. Each of the …
