Abstract: In this paper a concept will be presented that introduces a new element called forwarding mobile terminal (FMT) to the HiperLAN/2 (H/2) world. The FMT is designed to provide users in uncovered areas with access to the fixed Internet by providing an intermediate hop. The FMT is introduced in a way that it is backward compatible to existing H/2 equipment. The FMT is a modified H/2 mobil...

The aim of this paper is to contribute to partner’s network design beyond the common partner’s selection process usually made in the literature. The originality of our approach lies in compatibility concept that comes to consolidate the ordinary approach of partner’s selection. We suggest the use of product architecture to extract its related network of partners that would be analyzed with payi...

We study interacting components and their compatibility with respect to synchronous and asynchronous composition. The behavior of components is formalized by I/O-transition systems. Synchronous composition is based on simultaneous execution of shared output and input actions of two components while asynchronous composition uses unbounded FIFO-buffers for message transfer. In both contexts we st...

Support for multimedia applications by general purpose computing platforms has been the subject of considerable research. Much of this work is based on an evolutionary strat­ egy in which small changes to existing systems are made. The approach adopted here is to start ab initio with no backward compatibility constraints. This leads to a novel structure for an operating system. The structure ai...

This draft report organizes our work on this topic to date. The work will continue. Hence, the bulk of this report is an unfinished appendix. We have organized this work on the impact that software complexity has for aircraft safety by looking in two directions. Backward tracing asks the question, “What aspects of safety, V&V, and certification can be complicated by complexity?” Forward tracing...

In this paper, we introduce the notion of $$\mathbb {M}_2$$ -strict projections in $$M_2(\mathcal {M}_0)$$ where $$\mathcal {M}_0$$ is an abelian von Neumann algebra and prove that absolutely compatible pair strict elements a {M}$$ unitarily equivalent to $$\left( (1 - x_0) \otimes I_2 \right) P_0 + (x_0 I_2) P$$ P'$$ algebra, $$x_0$$ element {M}_0^+$$ , $$P_0 = \begin{bmatrix} 0 &{} \\ 1 \end{...

in recent decades, as a result of population growth, industrial developments, scarcity of sources, etc. more attention has been paid to spatial planning. spatial planning needs the consideration of different goals, scenarios, criterions and constraints, which leads us to the usage of spatial multi-criteria decision analysis (mcda) methods. the mail goal of this research is to develop a novel mo...
