Background Hemorrhage is a frequent hallmark of large acute reperfused myocardial infarctions (rMI). Recently, there has been a growing interest in CMR for noninvasive detection of hemorrhage in rMI. While T2*and T2-weighted CMR have been used for this purpose, there is a lack of consensus on which of these methods is the most appropriate and reliable. We investigated the relative abilities of ...

Magnetohydrodynamical evolution of the Richtmyer-Meshkov instability (RMI) is investigated by two-dimensional MHD simulations. The RMI suppressed a strong magnetic field, whereas amplifies an ambient field many orders magnitude if seed weak. We have found that suppression and amplification processes can be evaluated continuously along with amplitude Alfv\'en number $R_A$, which defined as ratio...

The virtual credit card processing system is an e-business system we have developed which provides a secure and universal mechanism for making purchases over the Internet. The system uses Remote Method Invocation (RMI), Java Server Pages (JSP), Java Servlets and Java Database Connectivity (JDBC). We also look at the possibility of implementing the system using the Web Services architecture.

Background: Risk of malignancy index (RMI) is the best method for discriminating benign and malignant pelvic masses. The aim of this study was to determine the RMI for preoperative evaluation of pelvic mass. Methods: This study was performed on 182 women with adenexal mass referred to Yahyahnejiad Hospital of Babol University of Medical Sciences in Iran from 2007 to 2009.The sensitivity, specif...

The parametric singleton design pattern combines the singleton design pattern with a parameter that enables unique creation of instances of a class. These instances are cached in a table. When a user asks for an instance with these parameters, the table is checked and instances are created conditionally. Parametric lazy instantiation causes instance creation, with the given parameters, if, and ...

Richtmyer–Meshkov instability RMI in gas-particle mixtures is investigated both numerically and analytically. The linear amplitude growth rate for a RMI in a two-phase mixture is derived by using a dusty gas formulation for small Stokes number St 1.0 , and it is shown that the problem can be characterized by mass loading and St. The model predictions are compared with numerical results under tw...

This paper presents a framework for automatic pedestrian and motor vehicle classification in a streetcrossing safety surveillance system. The proposed method is a coarse to fine classification approach divided into two branches. The moving objects are detected, tracked and clustered into fast moving and slow moving categories according to a motion speed estimation method. This approach is appli...

As we enter the 21st century, our dependency on the Internet is going to increase each day. This observation has inspired many researchers to invest their efforts into the development of efficient Web-based computing paradigms. JavaRMI is one alternative offered by Sun Microsystems. Using Java-RMI, a software developer can easily design and develop collaborative systems. In this article, we des...

Due to its high protocol overhead, both in data traffic and in round-trips, Java RMI is poorly suited for communication over slow wireless links. However, its performance can be enhanced without breaking compatibility with Java RMI specification, and with minimal changes to existing software and network hosts. This paper analyzes the reasons for the poor performance of Java RMI, outlines a solu...
