The class of autocorrelation functions of binary sequences is studied in terms of their finite-dimensional projections; that is, the vector ranges of finite sets of consecutive correlation coefficients. These are convex polyhedra whose extreme points can be generated by binary sequences of bounded periods. Algorithms are given for the calculation of the extreme points. Tables are presented for ...

it is near seventy years that the question of palestine and its occupation by the zionists has drawn attentions in iran. since the establishment of the zionist regime in palestine, many iranian politicians, intellectuals and even common people with various political backgrounds have paid attention to this question and have shaped several discourses in this regard. supporting the palestinian cau...

This paper deals with nonlinear equations f(x; ; )=0 and the corresponding ODEs xt=f(x; ; ) satisfying f(0; ; )=0 and a Z2-symmetry. In particular, we are interested in Hopf points, which indicate the bifurcation of periodic solutions of xt =f(x; ; ) from (steady-state) solutions of f(x; ; )= 0. It is shown that under suitable nondegeneracy conditions, there bifurcate two paths of Hopf points f...

In general, feature points and camera parameters can only be estimated with limited accuracy due to noisy images. In case of collinear feature points, it is possible to benefit from this geometrical regularity by correcting the feature points to lie on the supporting estimated straight line, yielding increased accuracy of the estimated camera parameters. However, regarding Maximum-Likelihood (M...

In the following paper, we present ​Noracle ​ , a tool for creating representational artefacts of metacognitive thinking in a collaborative, social environment. The tool uses only question­asking, rather than the typical question/answer paradigm found in threaded discussions, as a mechanism for supporting awareness and reflection on metacognitive activity, and for supporting self­regulated lear...

With the advancement of network technology and globalization of business, distributed software development has become in common. Along with this trend, distributed synchronous collaborative modeling supporting systems were proposed. This study points out two issues traditional systems have; they don’t relate conversations with model diagrams, and they can’t replay histories of modeling by assoc...
