Streszczenie:

In a single capture-recapture problem, two new Wilson methods for interval estimation of population size are derived. Classical Chapman interval, Wilson and Wilson-cc intervals are examined and compared in terms of their expected interval width and exact coverage properties in two models. The new approach performs better than the Chapman in each model. Bayesian analysis also gives a different way to estimate population size.

Streszczenie:

Metagenomics allows studying genetic potentials of microorganisms without prior cultivation. Since metagenome assembly results in fragmented genomes, a key challenge is to cluster the genome fragments (contigs) into more or less complete genomes. The goal of this project was to investigate how well CONCOCT bins assembled contigs into taxonomically relevant clusters using the abundance profiles of the contigs over multiple samples. This was done by studying the effects of different parameter settings for CONCOCT on the clustering results when clustering metagenome contigs from in silico model c

Unit testing is an important part of software testing that aids in the discovery of bugs sooner in the software development process. Extreme Programming (XP), and its Test First Design technique, relies so heavily upon unit tests that the first code implemented is made up entirely of test cases. Furthermore, XP considers a feature to be completely coded only when all of its test cases pass. However, passing all test cases does not necessarily mean the test cases are good. Extreme Coverage (XC) is a new approach that helps to assess and improve the quality of software by enhancing unit testing.

Multi-agent systems are extensively used in several applications. An important class of applications involves the optimal spatial distribution of a group of mobile robots on a given area, where the optimality refers to the assignment of subregions to the robots, in such a way that a suitable coverage metric is maximized. Typically the coverage metric encodes a risk distribution defined on the area, and a measure of the performance of individual robots with respect to points inside the region of interest. The coverage metric will be maximized when the set of mobile robots configure themselves a

BACKGROUND:Phylogenomic studies based on multi-locus sequence data sets are usually characterized by partial taxon coverage, in which sequences for some loci are missing for some taxa. The impact of missing data has been widely studied in phylogenetics, but it has proven difficult to distinguish effects due to error in tree reconstruction from effects due to missing data per se. We approach this problem using a explicitly phylogenomic criterion of success, decisiveness, which refers to whether the pattern of taxon coverage allows for uniquely defining a single tree for all taxa.RESULTS:We esta

To quantify the flow-oriented reliability and coverage-oriented reliability of WSNs with multistate nodes, this thesis proposes new metrics: WSN Reliability (WSNRel), Area-Coverage Reliability (ACR) and Coverage-oriented Reliability (CORE). WSNRel provides a minimal-path based approach to evaluate flow-oriented reliability of WSNs with multistate nodes. The metrics, ACR, and CORE, aim at quantifying the coverage-oriented capability of a WSN. To quantify ACR and CORE, Monte Carlo simulation approaches that utilize an energy matrix are presented.

On-chip coverage monitors are a possible solution, where a coverage monitor is a hardware circuit that sets to one when the coverage event of interest occurs. However, prior research has shown that the overhead is prohibitive for anything beyond a small number of coverage monitors. In this thesis, I explore techniques that reduce the

The application in wireless sensor networks (WSNs) is referred as barrier coverage. Previous research used an omni-directional sensing model for the barrier coverage. This thesis makes use of directional sensors to construct k-barrier coverage of a belt region. In the thesis, theoretical foundations for laying barriers with the directioanl sensing model is developed. A m

Streszczenie:

A wireless multicast network with a stringent decoding delay constraint and a minimum coverage requirement is characterized when the fading channel state information is available only at the receiver side. In the first part, the optimal expected rate achievable by a random user in the network is derived in a single antenna system in terms of the minimum multicast requirement in two scenarios: hard coverage constraint and soft coverage constraint. In the first case, the minimum multicast requirement is expressed by multicast outage capacity while in the second case, the expected multicast rate

Streszczenie:

Concurrency errors are notoriously difficult to debug because they may occur only under unexpected thread interleavings that are difficult to identify and reproduce. These errors are increasingly important as recent hardware trends compel developers to write more concurrent software and to provide more concurrent abstractions. This thesis presents algorithms that dynamically and systematically explore a program's thread interleavings to manifest concurrency bugs quickly and reproducibly, and to provide precise incremental coverage guarantees. Dynamic concurrency testing tools should provide (

In order to evaluate the link coverage and the mean spectrum efficiency in different environment, we consider a HetNet consisting of multiple tiers of BSs and randomly distributed users. In each user association scenario, the void probabilities of the BSs in each tier are found and the tight lower bounds on the link coverage and the mean

In this work, I propose new method which optimal number of sensor required in weep coverage.

Most of the apps are developed by small teams that could not afford expensive software process and maintain appropriate documentations. It would be interesting and pragmatic to develop testing tools to help test engineers in such a situation. We develop a software tool that crawls through the screen activities of an app to automatically learn the &;#64257;nite-state machine (FSM) of the app and then generates test cases with a certain adequacy criterion.

Unlike conventional omni-directional sensors that always have an omni-angle of sensing range; directional sensors may have a limited angle of sensing range due to technical constraints or cost considerations. Area coverage is still an essential issue in a directional sensor network. In this paper, we will discuss how to move sensors to the smaller overlap region or no overlapping areas to enhance coverage rate to maximize coverage for area coverage. We present distributed self-deploymen

Streszczenie:

The demand for cellular radio and personal communications services (PCS) continues to increase. Expectations for third generation wireless systems include higher data rates, improved quality of service, and ubiquitous coverage and access. Microcells with low base site transceiver antenna heights and small coverage areas are proposed to increase capacity. Microcellular architectures increase the frequency of handoffs and areas of low radio signal levels (radio "holes"). Accordingly, we propose multiple base site coverage with either extended overlapping microcells or macrocells overlaying
