one of the questions that has been ignored in letter of credit is a problem of assignment of proceeds in letter of credit that has been discussed generally below the transfer of lc subject, but has differed with it. so in this article, the author has tried to use the words assignment and transfer exactly in their place to clear the existent differences. at first, the writer’s hypothesis was tha...

A method for solving the descriptor discrete-time linear system is focused. For easily, it is converted to a standard discrete-time linear system by the definition of a derivative state feedback. Then partial eigenvalue assignment is used for obtaining state feedback and solving the standard system. In partial eigenvalue assignment, just a part of the open loop spectrum of the standard linear s...

there is not adequate information available about traditional instruction system in the field of visual arts in the pre-modern period. instruction of calligraphy can be considered as traditional instruction of art in a way that its guidelines and instructional texts are remained almost intact. instruction of calligraphy is implemented in aprofessor-student procedure and is accompanied with vari...

The infrared spectra of proline-rich proteins display a strong band in the 1450 cm(-1) region. In the literature, this band has been assigned either to the deformation modes of the CH(2) and CH(3) groups or to the CN stretching mode of proline residues. In order to establish the correct assignment of this band, the impact of proline vibrations in a polypeptide chain is studied and ab initio cal...

the automatic assignment of protein secondary structure from three dimensional coordinates is an essentialstep in the characterization of protein structure.although, the recognition of secondary structures suchas alpha-helices and beta-sheets seem straightforward, but there are many different definitions, eachregarding different criteria. we have developed a newalgorithm for protein helix assig...

The Personal Access Satellite System (PASS) strawman design, as described in the PASS Concept Study Report, (hereafter referred to as the Strawman Design) utilizes a hybrid Time Division Multiple Access (TDMA)/ Frequency Division Multiple Access (FDMA) implementation. TDMA is used for the forward direction (from Suppliers to Users), and FDMA for the return direction (from Users to Suppliers). I...

Recent infrared spectroscopic results from a new setup for the deposition of mass-selected ions in neon matrices are presented. The strong infrared signal observed for the asymmetric stretch of CNC and the appearance of the corresponding band for CNC in its natural isotopic abundance, demonstrates the sensitivity and usefulness of the apparatus. Evidence of a combination band of CNC involving t...
