MILE is an e-learning tool to support teaching, learning and student’s assessment during basic programming courses. This project integrates three existing educational systems: Mag, Svetovid and Testovid, developed by authors of the paper. Mag is the tutor for learning programming languages. Svetovid is system that helps instructors to leverage the effort of practical programming exercises and e...

In this paper we give an exact analytic solution for tachyon condensation in the modified (picture 0) cubic superstring field theory. We prove the absence of cohomology and, crucially, reproduce the correct value for the D-brane tension. The solution is surprising for two reasons: First, the existence of a tachyon vacuum in this theory has not been definitively established in the level expansio...

We rederive a relation between the genus-one GW-invariants of a quintic threefold in P and the genus-zero and genus-one GW-invariants of P. In contrast to the more general derivation in our previous paper, the present derivation relies on a widely believed, but still unproven, statement concerning rigidity of holomorphic curves in Calabi-Yau threefolds. On the other hand, this paper’s derivatio...

Thank you, John, for your very gracious introductory remarks. I'm rather surprised by what you've been able to extract from sources I once thought to be loyal. Dr. Podos, officers and members of the Association, ladies and gentlemen: I am profoundly grateful to the Trustees of ARVO for having invited me to deliver the Proctor Lecture. It is a great privilege to honor the memory of Dr. Francis P...

There are many methods for numerical solutions of integral equations. In various branches of science and engineering, chemistry and biology, and physics applications integral equation is provided by many other authors. In this paper, a simple numerical method using a fuzzy, for the numerical solution of the integral equation with the weak singular kernel is provided. Finally, by providing three...

New collision-finding attacks on widely used cryptographic hash functions raise questions about systems that depend on certain properties of these functions for their security. Even after new and presumably better hash functions are deployed, users may have digital signatures and digital time-stamp certificates that were computed with recently deprecated hash functions. Is there any way to use ...

In this paper we intend to examine the application of Kullback-Leibler, Hellinger and LINEX loss function in Dynamic Linear Model using the real price of oil for 106 years of data from 1913 to 2018 concerning the asymmetric problem in filtering and forecasting. We use DLM form of the basic Hoteling Model under Quadratic loss function, Kullback-Leibler, Hellinger and LINEX trying to address the ...
