in this research, the calculation method of aerodynamic loads on an airplane in all flight situations is presented. in order to find an calculation equation for aerodynamic loads on an airplane in all flight conditions, the f-5 aircraft is selected as a prototype is divided into one hundred small parts longitudinally. therefore, the numerical solutions are taken place in different conditions of...

The main purpose of this work is the comparison of several objective functions for optimization of the vertical alignment. To this end, after formulation of optimum vertical alignment problem based on different constraints, the objective function was considered as four forms including: 1) the sum of the absolute value of variance between the vertical alignment and the existing ground; 2) the su...

Maneuvering abilities have long been considered key factors that influence habitat selection and foraging strategies in bats. To date, however, very little experimental work has been carried out to understand the mechanisms that bats use to perform maneuvers. In the present study, we examined the kinematics of slow-speed turning flight in the lesser short-nosed fruit bat, Cynopterus brachyotis,...

A near-optimal midcourse trajectory shaping guidance algorithm is proposed for both air and ballistic target engagement mission attributes for generic long range interceptor missile. This guidance methodology is based on the maximum final velocity as the objective function and maximum permissible flight altitude as the in-flight state constraint as well as the head-on orientation as the termina...

the performance and flight behavior of the potato aphid macrosiphum euphorbiae was studied on the 'superior-bt' line transgenic for the cryiiia toxin of bacillus thuringien-sis (bt), resistant to the colorado potato beetle; and non transformed 'superior' line which served as control. mortality of the treated aphids was negligible and potato lines did not affect the development time of m. euphor...

For the inverse synthetic aperture radar (ISAR) imaging of a target at a long range, range alignment using the existing polynomial method brings about poor results because the flight trajectory changes depending on the initial position, and the motion parameters, meaning the polynomial cannot fit the trajectory. This paper proposes an improved range alignment method that models the trajectory u...

With recent advances in mass spectrometry (MS) technologies, it is now possible to study protein profiles over a wide range of molecular weights in small biological specimens. However, MS spectra are usually not aligned or synchronized between samples. To ensure the consistency of the subsequent analysis, spectrum alignment is necessary to align the spectra such that the same biological entity ...

The final goal of strategic management is to implement strategic plans, Therefore the alignment between corporate strategy and functional strategy is considerable. This study investigates the degree of alignment between HR strategy and corporate strategy of the national gas company. Data collection was conducted by questionnaire by 51 questions. The content validity of questionnaire was assesse...

We present an application of ABS algorithms for multiple sequence alignment (MSA). The Markov decision process (MDP) based model leads to a linear programming problem (LPP), whose solution is linked to a suggested alignment. The important features of our work include the facility of alignment of multiple sequences simultaneously and no limit for the length of the sequences. Our goal here is to ...
