Formation and structural assignments of four trimethylcyclopentadienes
Recueil des Travaux Chimiques des Pays-Bas, 1968AbstractThermolysis of isobornyl acetate in an inert gas atmosphere in a tube reactor, at temperatures between 420° and 480°C yields four trimethylcyclopentadienes as well as other compounds. Their isolation is described. Their structures were established by hydrogenation and by spectroscopic methods.A number of vicinal, allylic, homoallylic and long ...

Secondary structure-based assignment of the protein structural classes
Amino Acids, 2008Structural class categorizes proteins based on the amount and arrangement of the constituent secondary structures. The knowledge of structural classes is applied in numerous important predictive tasks that address structural and functional features of proteins. We propose novel structural class assignment methods that use one-dimensional (1D) secondary

Transitive Assignment Kernels for Structural Classification
2015Kernel methods provide a convenient way to apply a wide range of learning techniques to complex and structured data by shifting the representational problem from one of finding an embedding of the data to that of defining a positive semi-definite kernel.

Monothiodibenzoylmethane: Structural and vibrational assignments
Vibrational Spectroscopy, 2007Abstract The vibrational structure of the title compound (1,3-diphenyl-3-thioxopropane-1-one, TDBM) was studied by a variety of experimental and theoretical methods. The stable ground state configuration of TDBM was investigated by infrared (IR) absorption measurements in different media, by linear dichroism (LD) polarization spectroscopy of samples ...

The structural aspects of pole assignment
International Journal of Control, 1981The ability to assign the poles of a multivariable system, even under an imposed set of constraints ‘e.g. decentralized control’ is shown to reside completely in structural properties made explicit in the system digraph. A graph-theoretic approach to both the analysis and synthesis of multivariate control systems is then possible.

The Assignment Problem in Federal Structures
1977This paper contains a simple model of the assignment of functions among the jurisdictional levels that make up the public sector. The model rests on the notion that it is possible to classify the activities of individuals and governments who participate in the public sector and to impute costs—sometimes called transaction costs—to these activities ...

On the Assignment of Structure in Music Performance
Music Perception, 1996Cues for listeners' assignment of melodic structure are investigated in music performance. Performers' interpretations of musical structure can influence listeners' perceptions, especially when structural relations among musical events are ambiguous. Performances recorded on a computermonitored acoustic piano were compared with each performer's notated

Structural case assignment in Korean
2012In this dissertation, I aim to provide a theory on the distribution of structural Case in Korean. I propose the following Structural Case Assignment Hypothesis (SCAH) regarding the assignment of structural Case: "Structural Case is assigned by phase heads (C: nominative; v: accusative) to every argument in the c-command domain of the phase head at the ...
