Download or read book Magnetic Functions Beyond the Spin Hamiltonian written by David Michael P. Mingos and published by Springer. This book was released on 2010-11-22 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the spin-Hamiltonian formalism the magnetic parameters are introduced through the components of the Lambda-tensor involving only the matrix elements of the angular momentum operator. The energy levels for a variety of spins are generated and the modeling of the magnetization, the magnetic susceptibility and the heat capacity is done. Theoretical formulae necessary in performing the energy level calculations for a multi-term system are prepared with the help of the irreducible tensor operator approach. The goal of the programming lies in the fact that the entire relevant matrix elements (electron repulsion, crystal field, spin-orbit interaction, orbital-Zeeman, and spin-Zeeman operators) are evaluated in the basis set of free-atom terms. The modeling of the zero-field splitting is done at three levels of sophistication. The spin-Hamiltonian formalism offers simple formulae for the magnetic parameters by evaluating the matrix elements of the angular momentum operator in the basis set of the crystal-field terms. The magnetic functions for dn complexes are modeled for a wide range of the crystal-field strengths.

Available in PDF, EPUB and Kindle. Book excerpt: Humans have been “manually” extracting patterns from data for centuries, but the increasing volume of data in modern times has called for more automatic approaches. Early methods of identifying patterns in data include Bayes’ theorem (1700s) and Regression analysis (1800s). The proliferation, ubiquity and incre- ing power of computer technology has increased data collection and storage. As data sets have grown in size and complexity, direct hands-on data analysis has - creasingly been augmented with indirect, automatic data processing. Data mining has been developed as the tool for extracting hidden patterns from data, by using computing power and applying new techniques and methodologies for knowledge discovery. This has been aided by other discoveries in computer science, such as Neural networks, Clustering, Genetic algorithms (1950s), Decision trees (1960s) and Support vector machines (1980s). Data mining commonlyinvolves four classes of tasks: • Classi cation: Arranges the data into prede ned groups. For example, an e-mail program might attempt to classify an e-mail as legitimate or spam. Common algorithmsinclude Nearest neighbor,Naive Bayes classi er and Neural network. • Clustering: Is like classi cation but the groups are not prede ned, so the algorithm will try to group similar items together. • Regression: Attempts to nd a function which models the data with the least error. A common method is to use Genetic Programming. • Association rule learning: Searches for relationships between variables. For example, a supermarket might gather data of what each customer buys.

Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Niet afgebeeld. 1896 edition. Uittreksel: ...van kai met een verbaal woord, bij de verleden deelwoorden met raa, den passieven vorm met ndai en het participium passivum praesens. behandeld in 62, de eenigste vormen, waarin zich in het Bim. eene bepaalde passieve constructie ontwikkeld heeft. Dit is zeer begrijpelijk, bij de actieve constructie toch is het alleen maar eene zaak van vorm of men zegt: ta-bonto-ku kai malanta of ta-bonto-kai-ku malanta (vgl. de vorige ), bij de passieve constructie daarentegen gaat daaraan tevens verschil in beteekenis gepaard. Beteekenen toch, bijv. de van het eenvoudige diki (binden) afgeleide vormen raa-diki en ndai diki, dat, wat gebonden is en dat, wat te binden is (dat, wat gebonden wordt), zoo hebben de van het uit diki en kai samengestelde werkwoord diki afgeleide vormen raa-diki kai en ndai diki kai eene beteekeuis, die wij moeten omschrijven mei, dat, waarmede is gebonden," en dat, waarmede te binden is (gebonden wordt)." Heeft het werkwoord oorspronkelijk intransitieve beteekeuis, dan wordt het door samenstelling met kai transitief, zoodat er dus ook bovengenoemde passieve vormen van afgeleid kunnen worden, bijv. van mat (komen) raa-mai kai en ndai mai kai, de beteekenis van welke vormen wij moeten omschrijven met dat, waarmede (men) gekomen is" en dat, waarmede men komen moet (dat, waarmede men komt)." Wat de beteekenis dezer vormen betreft, is nog op te merken, dat zij behalve het instrument, ook nog de oorzaak kunnen aanduiden, in welk geval wij ze op bovengenoemde wijze kunnen omschrijven door in plaats van waarmede," waardoor" of waarom" te bezigen. De samenhang dezer beteekenissen is bekend genoeg (zie ook Aanm. U. na 140), alleen zij nog...
