Upon the outbreak of COVID-19, community wide mask wearing has become an important tool to prevent spread virus. The use disposable masks -that are generally produced three or more layers synthetic nonwovens- by general public is being questioned from environmental and waste perspective. Conventional textile fabrics, on other hand, may not provide desired level protection against In this study ...

This paper presents an approach for specifying reusable aspect models that define structure (using class diagrams) and behavior (using sequence diagrams). The high degree of reusability of the aspect models is demonstrated by modeling the design of 8 inter-dependent aspects of the AspectOptima case study. Based on this experience, several modeling language features that we deem essential to sup...

Because of the view independence and photo realistic image generation in diffuse environment, radiosity is suitable for an interactive walkthrough system. The drawback is time-consuming in form factor estimation, and furthermore, inserting, deleting or moving an object makes the whole costly rendering process repeat. To solve this problem, we encapsulate necessary information for form factor ca...

There has been a long-standing desire in computer science for a way of collecting and using libraries of standard software components. Unfortunately, there has been only limited success in actually doing this. We believe that the lack of success stems not from any resistance to the idea, nor from any lack of trying, but rather from the difficulty of choosing an appropriate formalism for represe...

The increasing complexity of software applications requires improved software development techniques in order to cope with, a.o., software reuse and evolution, the management of heterogeneous features, and the retargeting of systems towards new SW platforms. The introduction of aspect-oriented software development (AOSD) and the support for model-driven development (MDD) are two important and p...

This paper analysis approaches and possibilities of executive model aimed to MDA approach. The second part of the article proposes guideline to create executive model, describes basic interactions to object oriented approach and shows possibilities of creating a core of executable model in Java programming language. Annotations are used for executive model object extension. Reflection concept i...

In my previous article, http://www.jot.fm/issues/issue_2004_01/column7, we discussed how large reusable assets could provide the seed to design and build complex solutions. As a quick recap we reused large-grained composite e-business patterns (http://www106.ibm.com/developerworks/patterns/select-pattern.html) within a methodology that was modified to match customer requirements to an appropria...

In support of collaboration among individuals whose work involves exploration of data networks (such as the World Wide Web, or sets of intelligence information, or more detailed databases of scientific information), some researchers are examining a problem that I will call “quest reuse”. The central idea is that a person doing such research is on a quest that has specific goals. Those goals are...
