We study the possibility of constructing a Sobolev-Schwartz generalized solution to the problem A(t)x'(t) + B(t)x(t) = f(t), t G T = [0, + infinity), x(0) = a, whose coefficient (n x n)-matrix of derivatives is de...

We study the possibility of constructing a Sobolev-Schwartz generalized solution to the problem A(t)x'(t) + B(t)x(t) = f(t), t G T = [0, + infinity), x(0) = a, whose coefficient (n x n)-matrix of derivatives is degenerate for every t is an element of T in the situation when there is no classical solution x(t) is an element of C-1(T) (the initial data do not satisfy the agreement conditions and the right-hand side is not a sufficiently smooth vector-function). We prove that the generalized solution is the limit of a sequence of classical solutions of the Cauchy problem for a system with constant coefficients, obtained by the perturbation method.

Today, PDF is one of the most popular document formats in the web. Many PDF documents are not images, but remain untagged. They have no tags for identifying the logical reading order, para- graphs, figures, and tables. One of the challenges with these doc- uments is how to extract tables from them. The paper discusses a new system for table structure recognition in untagged PDF doc- uments. It is formulated as a set of configurable parameters and ad-hoc heuristics for recovering table cells. We consider two dif- ferent configurations for the system and demonstrate experimental results based on the existing competition dataset for both of them.
