Описание:Four common image clustering algorithms are evaluated: k-means clustering and three versions of hierarchical clustering, using average-linkage, complete-linkage, and Ward' s method. In the experimental section of the book, the algorithms are compared using two similarity measures: color-based similarity utilizing MPEG-7 color descriptors only, and total similarity as a weighted sum of features for both color, texture and shape. The experiments show average-linkage hierarchical clustering performing best according to both similarity measures. Notably, though, the addition of texture and shape features degraded the cluster quality of all the three hierarchical methods tested, but improved the quality of k-means clustering. This book describes the clustering process, focusing on clustering algorithms and ways to measure the quality of the created clusters. The image clusters are utilized by content-based image retrieval and querying systems that require effective query matching in large image databases. To be able to retrieve a set of image documents, the images must be clustered according to semantic similarity.

Mastering VMware® Infrastructure3

Master ItPFive ESX Server hosts need to be grouped together for the purpose of enabling the Distributed Resource Scheduler (DRS) feature of VI3. Configure and manage Distributed Resource Scheduling (DRS).PDRS builds off the success and efficiency of VMotion by offering an automated VMotion based on an algorithm that analyzes system workloads across all ESX Server nodes in a cluster.P Master It A DRS cluster should determine on which ESX Server host a virtual machine runs when the virtual machine is powered, but it should only recommend migrations for VMotion. Master ItPA DRS cluster should determine on which ESX Server host a virtual machine runs when the virtual machine is powered on, and it should also manage where it runs for best performance. A VMotion should only occur if a recommendation is determined to be a four- or five-star recommendation. Master ItPTwo virtual machines running a web application and a back-end database should be kept together on an ESX Server host at all times. If one should be the target of a VMotion migration, the other should be as well ...»

Multi-Baseline SAR Imaging. Models and Algorithms
A unified treatment of SAR Tomography (T-SAR) and Interferometry (InSAR) will be provided by considering the multi-image SAR system as a a tool for the 3D reconstruction of the upper portion of the Earth' s surface. By virtue of this interpretation, T-SAR and InSAR will be introduced as the result of particular hypotheses about the imaged scene. Such scenes are typically investigated through interferometric techniques, in order to estimate the topographic profile and the displacement field undergone in the observation time. In the case of forested areas the object under analysis is commonly represented by the vertical structure of the trees, to be inferred through tomographic techniques. Due to the variety of scenarios that are commonly imaged by SAR sensors, different kinds of analyses will be taken into account. The opposite case is given by scenarios for which surface scattering can be assumed. The scope of this dissertation is to provide a discussion about the exploitation of multiple SAR images for the remote sensing of natural scenarios, and describe new procedures to infer information from the data.

FULLERENE-BASED SYSTEMS AS PROSPECTIVE SPIN CLUSTER QUBITS. QUANTUM MECHANICAL TREATMENT OF DIMER AND TRIMER FULLERENE SYSTEMS DOPED WITH VARIOUS METAL AND NON-METAL ELEMENTS
Starting with Richard Feynman' s idea of possibility of quantum mechanical computers success of the special quantum algorithms proposed by Deutsch and Jozsa, Grover and Shor attracted the field of physical implementations of quantum computers. Nuclear or electron spins of metal and non-metal atoms inside the fullerenes serve as spin-qubits in these systems. We already know that carbon based materials have attracted huge interest in chemistry, physics, material science and biology after the discovery of C60 fullerene, carbon nanotube and endohedral fullerene. The book contains the first principle electronic structure calculations of Li,Na,N and P doped carbon dimer and trimer fullerenes in order to investigate their spin qubit properties in the field of fullerene based quantum computer proposals. Endohedrally doped fullerene chains can be a promising candidates in spin based quantum computer proposals because carbon based materials believed to have long spin coherence times due to low spin orbit coupling and provide isolated electronic properties allowing well defined spin-qubits.
