C-13-alkylated methoxy-8tf-dibenzo[a,g]quinolizin-8-ones 2a-e were synthesized by photocyclization of 1 -alkylidene-N-benzoyl-1,2,3,4-tetrahydroisoquinolines 1. Moreover, condensation of l,2,3,4-tetrahydro-6,7-dimethoxy-l-oxo-isoquinoline with homophthalic acid anhydrides 7a and b leads to the C-13-alkylated 8-oxoberbines 2b and c and improves the yields compared with those of the photocyclizat...

A series of new fluorene bisamide derivatives were synthesized through multi-component Ugi reaction and tested for their in-vitro anti-mycobacterial activity. The structures of the products 5a-w were deduced from their IR, 1H NMR, and 13C NMR spectra. Elemental analyses (CHN) for novel compounds (5a, 5d, 5f, 5h, 5k, 5l, 5p, 5s, 5t, 5v, 5w) was done. These compounds were evaluated as anti-bacter...

the biologists now face with the masses of high dimensional datasets generated from various high-throughput technologies, which are outputs of complex inter-connected biological networks at different levels driven by a number of hidden regulatory signals. so far, many computational and statistical methods such as pca and ica have been employed for computing low-dimensional or hidden representat...

This paper is devoted to application of neural network with a specific restricted connectivity structure for identification and control of a real process. Parameters of the identified model are used to design a controller based on dynamic feedback linearization. The designed neural network based controller is verified on mathematical model within MATLAB/Simulink environment and applied to the r...

this paper presents an accurate differential global positioning system (dgps) using multi-layered neural networks (nns) based on the back propagation (bp) and imperialistic competition algorithm (ica) in order to predict the dgps corrections for accurate positioning. simulation results allowed us to optimize the nn performance in term of residual mean square error. we compare results obtained b...

Handwriting recognition has been one of the active and challenging research areas in the field of image processing and pattern recognition. It has numerous applications that includes, reading aid for blind, bank cheques and conversion of any hand written document into structural text form. Neural Network (NN) with its inherent learning ability offers promising solutions for handwritten characte...
