This paper presents a Control Allocation formulation aimed at altering the dynamic transient response of an aircraft by exclusive means aerodynamic effectiveness its control effectors. is done, for given Flight System architecture and, optionally, closed-loop performance, exploiting concept Center Pressure, i.e. center pressure due to only forces. Two formulations are proposed, and their advant...
II. Methods Tested. Three codes were selected from SHARE which represented three different methods. A. Jacobi. SHARE distribution 705 by MIT computing lab (FORTRAN). This is the original version of the Jacobi method [1] in which plane rotations are used to produce zeros in all off-diagonal positions using the maximum off-diagonal element as a pivot at each step. This is probably slower but more...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
We define a family of braid group representations via the action R-matrix (of quasitriangular extension) restricted quantum $\mathfrak {sl}(2)$ on tensor power simple projective module. This is an extension Lawrence representation specialized at roots unity. Although center has finite order representations, this faithful for our extension.
this paper analyzes a linear system of equations when the righthandside is a fuzzy vector and the coefficient matrix is a crisp m-matrix. thefuzzy linear system (fls) is converted to the equivalent crisp system withcoefficient matrix of dimension 2n × 2n. however, solving this crisp system isdifficult for large n because of dimensionality problems . it is shown that thisdifficulty may be avoide...
Recent Monte Carlo research (Lance, Woehr, & Meade, 2007) has questioned the primary analytical tool used to assess the construct-related validity of assessment center post-exercise dimension ratings (PEDRs) – a confirmatory factor analysis of a multitrait-multimethod (MTMM) matrix. By utilizing a hybrid of Monte Carlo data generation and univariate generalizability theory, we examined three pr...
Computed tomography (CT) using metrizamide is a valuable tool in the neuroradiologic evaluation of the spinal cord, but CT must be used with care when measuring object size because size may vary with different window center (level) settings. A simple method to determine appropriate window center (level) settings during CT object measurement is described. A polystyrene core with a Teflon outer c...
Insulators might regulate gene expression by establishing and maintaining the organization of the chromatin fiber within the nucleus. Biochemical fractionation and in situ high salt extraction of lysed cells show that two known protein components of the gypsy insulator are present in the nuclear matrix. Using FISH with DNA probes located between two endogenous Su(Hw) binding sites, we show that...
Energy Dependence of the NN t-matrix in the Optical Potential for Elastic Nucleon-Nucleus Scattering
The influence of the energy dependence of the free NN t-matrix on the optical potential of nucleon-nucleus elastic scattering is investigated within the context of a full-folding model based on the impulse approximation. The treatment of the pole structure of the NN t-matrix, which has to be taken into account when integrating to negative energies is described in detail. We calculate proton-nuc...
