Due to geographic and climatic conditions in mountainous northwest area, Roads in these areas are often covered with snow, ice and mud. Hence Transportation of equipment and soldiers encounter hardship and difficulties in rural area and specially outposts. To solve these problems, it is needed to fabricate portable roadway or traction mats. These high strength mats cover surface of roads and ar...

Title of dissertation: HEAP DATA ALLOCATION TO SCRATCH-PAD MEMORY IN EMBEDDED SYSTEMS Angel Dominguez Doctor of Philosophy, 2007 Dissertation directed by: Professor Rajeev K. Barua Department of Electrical and Computer Engineering This thesis presents the first-ever compile-time method for allocating a portion of a program’s dynamic data to scratch-pad memory. A scratch-pad is a fast directly a...

We solve the Angel Problem, by describing a strategy that guarantees an Angel of power 2 or greater to win. Basically, the Angel should move north as quickly as possible. However, he should detour around eaten squares, as long as the extra distance does not exceed twice the number of eaten squares evaded. We show that an Angel following this strategy will always spot a trap early enough to avoi...

The Angel-Devil game is an infinite game played on an infinite chess board: In each move the Angel, a generalized chess king, jumps from his current square to some location at distance at most k, while his opponent, the Devil, blocks squares trying to strand the Angel. The Angel wins if he manages to fly on forever. It is a long-standing open question whether some Angel of sufficiently large po...

The angel game, as described in [BeCG], has two players the “angel” and the “devil” who play alternately on the 2-dimensional integer lattice, Z. We refer to lattice points as vertices, and write o = (0, 0) for the origin. The angel has a certain fixed power p. (We refer to it as a p-angel .) It starts the game at the origin, and at each play moves to another vertex so that the change in each c...

At the time of an initial public offering, shares in a firm are typically held by venture capitalists, insiders, corporate investors, and angel investors. We examine the role of angel investors in the IPO process. We find that angel investors provide equity capital in industries that venture capitalists are less likely to serve and that shareholders in angel backed IPO firms are more likely to ...

We solve Conway’s Angel Problem by showing that the Angel of power 2 has a winning strategy. An old observation of Conway is that we may suppose without loss of generality that the Angel never jumps to a square where he could have already landed at a previous time. We turn this observation around and prove that we may suppose without loss of generality that the Devil never eats a square where t...

Recently the so called angel problem was solved independently by four authors. We establish an analogous theorem for triangulations of the plane and derive a solution to the original angel problem from this theorem. Compared to earlier solutions, our approach gives a simpler proof as well as a weaker winning angel. We show that an angel moving from the middle square to any other square of a 3 b...
