With the renewed emphasis in control theory on qualitative structural issues, as distinct from techniques of optimization, the last decade has brought significant growth in the application of geometric ideas to the formulation and solution of problems of controller synthesis. In this article we review the status of geometric state space theory as developed for application to systems that are linear, multivariable and time-invariant. After a brief summary of the underlying geometric concepts (( A , B )-invariant subspaces and ( A , B )-controllability subspaces) we outline two standard problems of feedback control that have been successfully attacked from this point of view, and briefly survey recent results in a range of other topic areas. Then we discuss certain issues of methodology, and conclude with some remarks on computational procedures.
In computer vision, texture plays an important role. In this work we propose five human perceptual texture features heuristically extracted. Since a modeling can not be obtained from these features, we use a discrimin...

In this paper we study how the language cocktails are composed. How many languages are used in each software projects, which language types are used and which languages are typically used together. Our study was done on a sample of over 15,000 projects from the largest software forge, GitHub. The results show that many languages are used in each project: 96% projects employ at least 2 languages, over 50% employ at least two programming languages. Finally, there are strong relations between different languages: hence sets of languages tend to be adopted together. Copyright 2014 ACM.
