Let M be a closed oriented 3-manifold which can be triangulated with N simplices. We prove that any map from M to a genus 2 surface has Hopf invariant at most C . Let X be a closed oriented hyperbolic 3-manifold with injectivity radius less than ǫ at one point. If there is a degree non-zero map from M to X, then we prove that ǫ is at least C . In the 1970’s, Thurston invented simplex straighten...

In the present study, field oriented control of step motor implementation has been analyzed sothat it can make a Sensorless control. Efficiency and Facilities of step motor is more than othertypes of electromotor. Therefore, the numbers of mechanisms and different types of turning canbe made into them. Also controlling these motors is easier than other available motors. Steppingmotor has been d...

one of the modern paradigms to develop an application is object oriented analysis and design. in this paradigm, there are several objects and each object plays some specific roles in applications. in an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. for the procedural semantics, we can write a ...

Object-role Modeling (ORM) is a fact-oriented modeling approach for specifying, transforming, and querying information at a conceptual level. Unlike Entity-Relationship modeling and Unified Modeling Language class diagrams, fact-oriented modeling is attribute-free, treating all elementary facts as relationships. For information modeling, fact-oriented graphical notations are typically far more ...

Alliances represent a variety of governance contexts, and hence provide a rich empirical setting for studying the value-creation mechanisms of Information Technology (IT). We examine the influence of IT investment and flexible IT infrastructure, through Service Oriented Architecture (SOA), in the effect of alliance activity on firm performance. We find that the marginal contribution of each joi...
