Using the Activity Vector Analysis to Determine Teacher Dispositions for Charter School Teachers in Urban High Schools
This study examined responses to the Activity Vector Analysis by both teachers and students in two urban charter high schools. The premise of this research was that the five dispositions of assertiveness, sociability, calmness, conformity, and conscious restraint were needed to be successful …

Diagnosis of Loblolly Pine (Pinus taeda L.) Nutrient Deficiencies by Foliar Methods
… optimal nutrient ratios, DRIS methodology, vector analysis, and changes in individual fascicle and total current year foliage weight/area were used to identify deficiencies. Phosphorus was repeatedly indicated as most limiting growth at TX while K was implicated at SC. The GA site revealed …

Analysis of soft charging switched capacitor power converters
… with switch capacitor converters. A topology analysis is performed to determine which topologies can support soft-charging, and the Dickson charge pump is selected for the continued development of soft-charging control. The specifics of adapting soft-charging to the Dickson topology are …

Optimisation of chaotic thermoacoustics
… system. First, we propose covariant Lyapunov vector analysis as a tool to calculate the stability of chaotic acoustics, making connections with eigenvalue and Floquet analyses. Second, covariant Lyapunov vector analysis is applied to an acoustic system with a heat source. We find that …

The Navier-Stokes equations for elliptic quasicomplexes
… of hydrodynamics are usually written in terms of vector analysis. More promising is the formulation of these equations in the language of differential forms of degree one. In this way the study of Navier-Stokes equations includes the analysis of the de Rham complex. In particular, the Hodge theory …

Applications of a generalized integral transform to vibrations of continuous media
… from which approximate eigenvalues and eigenvectors were obtained. The differential equations were uncoupled using a transformation matrix of the eigenvectors and then were solved for the generalized time function. Finally, the inversion series for the transform was used to obtain the …
