Abstract: |
It is widely acknowledged within the software community
that requirements quality is one of the most important factors in the success
of software projects. In this article, we show how XML and XSLT can be used
to implement requirements verification heuristics that can help to discover
hidden conflicts and defects in requirements expressed in natural language.
This approach is based on the representation of requirements in XML and in
the usage of XSLT stylesheets (i.e. XML to
XML, XML to HTML or XML to text transformation stylesheets)
not only to automatically generate requirements documents, but also to
provide some verification heuristics based on requirements–oriented metrics.
These ideas have been implemented in REM, an experimental XML–based
requirements management tool also described in this article. |

Abstract: |
An important aspect of parallel computing is the synchronization and communication between all the pieces involved in the computation that may be carried out across multiple processors or computers on a network. In this paper we present a prototype of a simple operating system that support parallel computing. Although a lot of research in this area has been conducted, most are sophisticated large-scale projects involving multi-year efforts of multi-person research teams. Simple, robust, cost effective small-scale operating systems are still needed to support most every-day parallel computing tasks. The operating system discussed in this paper is such an attempt. It uses a reliable message transmission protocol for communications between machines over a network. A simulated version of the operating system is designed and implemented. the connected blocks of characters. |

Abstract: |
Nowadays, PC and 3D graphics technology are developing rapidly. Rapid
progress of hardware technology enabled anybody to assort 3D graphics
environment, with functions matching those of workstations few years before,
in moderate prices. 3D graphics is no longer an exclusive property of few
professionals. However, specialized input devices
for manipulation in 3D graphics environment is too expensive for users to
purchase and this is the main reason why 3D input devices are not widely
used. Also, 3D object manipulation interface in existing desktop environment
lack accuracy and correction of error is cumbersome. To overcome these
shortcomings, study for effective 3D interface using basic 2D based input
devices in popularized desktop environment is required. Hence, an interface
that helps accurate selection and manipulation of objects in 3D virtual
environment using 2D mouse is proposed in this paper. When user selects a
certain object, a selection tree internally composed of the selected object
and selectable candidate objects are built and following the traversal of
users of the selection tree, exact object selection and manipulation become
possible. We design 2D mouse based 3D object manipulation interface that
supports translation and rotation of objects connected to the new object
selection method and a prototype is built. This technique can contribute to
improving manipulation in areas that need exquisite 3D object manipulation
such as IETM and animation tools. |

Abstract: |
Procurement of
production goods and services has been the subject of automation for the past
decade. Retailers have implemented supply chain management (SCM) systems in
the 1960s. SCM applications have expanded the scope of traditional SCM systems
as the advent of Internet enables enterprises to perform their business transactions
ubiquitously. That is, e-SCM (electronic-SCM) eliminates the constraints of
time and distance in operating a business, managing the cooperation of system
components in a supply chain. Access control mechanisms in e-SCM are one of
important security concerns to enable each system component to access
sensitive information in a secure manner. In this paper, we propose a
consolidated access control mechanism for e-SCM. This mechanism ensures that system components in e-SCM systems can
access resources based on their role information. |

Abstract: |
In developing application software, it is important to
pay attention to end-users' viewpoints. In particular, in designing Graphical
User Interfaces (GUIs), it is effective to develop a prototype and to show it
to end-users in order to reflect end-users' viewpoints, because the GUI
design strongly affects the usability of the application. Use case diagrams
and scenarios in Unified Modeling Language (UML) can be described from
end-users' viewpoints. Therefore, it is considered that GUIs reflecting
end-users' viewpoints can be developed based on the use case diagrams. In
this paper, we propose a method for extracting GUI-based control struc |

Abstract: |
Interoperability of heterogeneous applications is defined
as the ability for multiple software applications written in different
programming languages running on different platforms with different operating
systems to communicate and interact with one another over different computer
networks. The emerging middleware technologies, including CORBA, COM/DCOM,
and Enterprise JavaBeans offer an industrial de facto standard communication

Abstract |
Performance
engineering techniques have been traditionally applied to computer devices
and networks and more recently also to software systems. In this paper we
propose to use them in an unusual context, i.e., in multiproject
software development environment to support manager’s decisions. The basic
idea is that project teams correspond to the processing elements of a
performance model, and project intermediate phases to the tasks to be
performed within established time intervals. The
