Although the Java package is incomplete in this regard, it represents a good foundation when combined with an advanced programming environment inspired by Vesta. The few ways in which the Java package is unsuitable appear to be correctable with careful programming conventions and support from the environment.

Typed, immutable objects combined with ubiquitous versioning provide a much more sound basis. A prototype configuration management system cur- rently under development relies upon persistent objects provided by a commercial object-oriented database sys- tem. Mechanisms and

NOEMOL: integrated molecular graphics and the simulation of Nuclear Overhauser effects in NMK spectroscopy

Journal of Molecular Graphics, 1989

Nuclear Overhauser effects (NOEs) are a widely used method of determining the spatial proximity o... more Nuclear Overhauser effects (NOEs) are a widely used method of determining the spatial proximity of spins in Nuclear Magnetic Resonance (NMR) spectroscopy. This paper describes a C program developed for the Sun-3 workstation family that allows the computation of multispin NOE effects for a given molecular structure and given NMR parameters (i.e., resonance frequency and correlation time for molecular reorientation). The integration of these facilities with simple molecular graphics display routines allows modifications to the molecular conformation (such as bond rotations) to be performed, and the effect of these modifications on the NOE effects can then be rapidly calculated and easily visualized. Using the Sun windowing system, the NOE effects can be calculated for two (or more) candidate structures and compared to experimental NMR results. The overall molecular reorientation can be modeled by either isotropic or symmetric top diffusion models, and the internal motions of methyl groups are modeled using an algorithm reported by Tropp.

Providing Orthogonal Persistence for Java (Extended Abstract)

This is a simple consequence of the fact that most software is written to support human activities and many human activities continue for days, weeks, months or even tens of years. The design of an aircraft or the construction and

It is also a useful tool that can be used now to experience the advantages of orthogonal persistence for a popular language. Many research challenges remain. Perhaps the primary ones are: – Developing a better understanding of the different nature of applications and

The model for checkpointing the state of a computation, including live threads, is analyzed and related to a transactional approach. The problem of dealing with state that is external to the PJama environment is explained and

Extending a J2EETM Server with Dynamic and Flexible Resource Management

A single J2EE server can support multiple applications much like a traditional operating system, but performance levels can be difficult to control, due to the absence of resource management facilities in the Java platform. The Resource Management (RM) interface

Orthogonal Persistence for the Java Platform

Software: Practice and Experience, 2006

Similar to an operating system, a J2EE server can host multiple applications, but this is rarely seen in practice due to limitations on scalability, weak inter-application isolation and inadequate resource management facilities in the underlying Java platform. This leads to a proliferation of server instances, each typically hosting a single application, with a consequent dramatic increase in the total memory footprint and more complex system administration. The Multi-tasking Virtual Machine (MVM) solves this problem by providing an efficient and scalable implementation of the isolate API for multiple, isolated tasks, enabling the co-location of multiple server instances in a single MVM process. Isolates also enable the restructuring of a J2EE server implementation as a collection of isolated components, offering increased flexibility and reliability. The resulting system is a step towards a complete and scalable operating environment for enterprise applications.

The reason for this choice was that the low weight and small size of the spectrometer to be carried by the person in the radiation field are more important than an excellent energy resolution . This paper deals with the generation of the response matrix for the CdTe detectors and with the unfolding procedure.
