متن کاملA Review of Travelling Wave Solutions
In this paper we review the existence of diierent types of travelling wave solutions u(x; t) = (x ? ct) of degenerate non-linear reaction-diiusion equations of the form u t = D(u)u x ] x + g(u) for diierent density-dependent diiusion coeecients D and kinetic part g. These include the non-linear degenerate generalized Fisher-KPP and the Nagumo equations. Also, we consider an equation whose diius...
متن کاملToward nonlinear stability of sources via a modified Burgers equation
Coherent structures are solutions to reaction-diffusion systems that are time-periodic in an appropriate moving frame and spatially asymptotic at x = ±∞ to spatially periodic travelling waves. This paper is concerned with sources which are coherent structures for which the group velocities in the far field point away from the core. Sources actively select wave numbers and therefore often organi...
متن کاملThe Design of an Attitude Control System for a Space Vehicle
The system considered la representative of certain inertially stabilized attitude control systems for NASA Space Vehicles. Its design is presented in order to indicate how such systems may be designed using various available analytical and graphical procedures. The essential problem is to select appropriate compensating network parameters such that for a range of variations of the angles betwee...
متن کاملImproving the Operation of Text Categorization Systems with Selecting Proper Features Based on PSO-LA
With the explosive growth in amount of information, it is highly required to utilize tools and methods in order to search, filter and manage resources. One of the major problems in text classification relates to the high dimensional feature spaces. Therefore, the main goal of text classification is to reduce the dimensionality of features space. There are many feature selection methods. However...
