OBJECTIVE To investigate the cross-cultural validity of international Dutch-English comparisons when using the Dutch Rivermead Mobility Index (RMI), and the intra-test reliability and construct validity of the Dutch RMI. METHODS Cross-cultural validity was studied in a combined data-set of Dutch and English patients undergoing rehabilitation after stroke, who were assessed with the Dutch vers...

Background/Aim. Ovarian cancer is the leading cause of death from gynecologic malignancies. Risk of malignancy index (RMI) is recommended in assessment of patients with adnexal masses. The aim of this study was to verify the effectiveness of the RMI in the discrimination between benign lesions and malignant adnexal masses in clinical practice. Methods. Ultrasounds were performed for all the pat...

A new implementation of RMI named OnePort RMI is proposed in this paper. OnePort RMI consists of new RMI runtime, classes which are implemented interfaces by RMI specification, and MultiChannelSocketFactory. Using OnePort RMI, when an object on a client invokes methods of remote objects on a server, the client can use sockets of different types to connect one destination port at the same time, ...

Background: Counselling and rapid referral to a specialised facility might be improved with the use of scoring system that could diagnose ovarian cancer. The relative simplicity Risk Malignancy Index (RMI) technique ease which it may applied make strong candidate as primary diagnostic tool for individuals pelvic masses. Methods: Prospective observations study conducted on women diagnosed mass b...

In current Java implementations, Remote Method Invocation is slow. On a Pentium Pro/Myrinet cluster, for example, a null RMI takes 1228 μs using Sun’s JDK 1.1.4. This paper describes Manta, a Java system designed to support efficient communication. On the same Myrinet cluster, Manta achieves a null RMI latency of 35 μs. Manta is based on a native Java compiler. It achieves high communication pe...

Java RMI provides a simple and elegant paradigm for communication with objects in remote address spaces. RMI is a de facto standard for communication in distributed systems that are written in di erent languages and optimized to run in disparate environments. XML [10] has emerged as a promising standard for language-independent data representation, and HTTP as a widely-used rewall-friendly netw...

This paper describes RuCOS runtime code generator for object serialization embedded into RMI. We developed RuCOS and a modified Java RMI. The feature of RuCOS is dynamic code generation for serialization / deserialization at runtime. We can improve the performance of RMI using RuCOS in comparison with standard Java RMI. In this paper, the implementation issues of RuCOS are described. Key-word: ...

Java’s support for parallel and distributed processing makes the language attractive for metacomputing applications, such as parallel applications that run on geographically distributed (wide-area) systems. To obtain actual experience with a Java-centric approach to metacomputing, we have built and used a high-performance widearea Java system, called Manta. Manta implements the Java RMI model u...

Distributed object-oriented platforms are increasingly important over wireless environments to provide frameworks for collaborative computations and for managing a large pool of distributed resources. Due to limited bandwidths and heterogeneous architectures of wireless devices, efforts are needed to support object-oriented frameworks over heterogeneous wireless environments and optimize system...
