the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

Numerical Time Integration for Air Pollution Models

Due to the large number of chemical species and the three space dimensions, o -the-shelf sti ODE integrators are not feasible for the numerical time integration of sti systems of advection-diffusion-reaction equations @c @t +r (uc) = r (Kr c) +R (c) ; c = c(x; t); c 2 IRm; x 2 IR3 from the eld of air pollution modelling. This has led to the use of special time integration techniques. This paper...

Beyond massive parallelism: numerical computation using associative tables

Novel computing devices are exploited for numerical computation. The solution of a numerical problem is sought, which has been solved many times before, but this time with a di erent set of input data. A table is a classical way to collect the old solutions in order to exploit them to nd the new one. This process is extended to more general problems than the usual function value approximation. ...

Explore the Matrix: Browsing Numerical Data Tables Using Sound

When first approaching a two-dimensional (2D) data table, a user often wants to get a quick overview of the data before analysing them in more detail. Blind and visually impaired people cannot do this task at all using visual displays. Furthermore, speech synthesisers do not help sufficiently with browsing and pattern identification. The approach taken in this research work is to use other sens...
