Horizon Mass Theorem Honorable Mention Gravity Research Foundation 2005

A new theorem for black holes is found. It is called the horizon mass theorem. The horizon mass is the mass which cannot escape from the horizon of a black hole. For all black holes: neutral, charged or rotating, the horizon mass is always twice the irreducible mass observed at infinity. Previous theorems on black holes are: 1. the singularity theorem, 2. the area theorem, 3. the uniqueness the...

Honorable Mention for CNUR816: Health Assessment at Ryerson University

Contest TTC 2014

ion Level. Our solution combines imperative code in Java and declarative scripts in ETL andEGL. As a result, according to the evaluation criteria [2], the abstraction level of (a) the Java code to launchtransformations is low, (b) XML to XML-model transformation is low, (c) XML-model to Object-modeltransformation is high, (d) Object-model to code transformation is high, and (e) the ...

A Forensic Analysis of a Distributed Two-Stage Web-Based Spam Attack (Awarded Honorable Mention!)

Open mail relays have long been vilified as one of the key vectors for spam, and today – thanks to education and the blocking efforts of open relay databases (ORDBs) – relatively few open relays remain to serve spammers. Yet a critical and widespread vulnerability remains in an as-yet unaddressed arena: web-based email forms. This paper describes the effects of a distributed proxy attack on a v...

Geometry: Combinatorics & Algorithms Lecture Notes Hs 2014

Preface These lecture notes are designed to accompany a course on Geometry: Combinatorics & Algorithms that we teach at the for the rst time in the winter term 2014. The course is a synthesis of topics from computational geometry, combinatorial geometry, and graph drawing that are centered around triangulations, that is, geometric representations of maximal planar graphs. The selection of topic...
