The insertion of phenyl acetylenes at the reactive positions indeno[1,2- b ]fluorene leads to tune its optoelectronic and magnetic properties. Furthermore, single-molecule conductance has been investigated for first time.

Engineering, education to workplace, is not just about technical knowledge. Rather, who becomes an engineer and why says much about the profession. Engineering has a “diversity” problem. Like all professions, it must narrow the gap between practitioners on the one hand, and their clientele on the other; it must become “culturally competent.” Given the current composition of the engineering facu...

While software design is increasingly based on models, requirements engineering is generally performed using structured text; as a consequence, only a weakly structured connection to design is possible. Model-based requirements engineering can bridge this gap. With AutoRAID we introduce a tool prototype supporting a structured and integrated requirements model, and operations for refinement and...

The inertness of today’s software systems turns innovative applications into an obstacle rather than an enabler and results in dependability degradation during the systems’ lifetime. Even more so, heterogeneity, scale, and dynamics open up what Laprie called the dependability gap. In this position paper, we identify the need to converge methods from software engineering with traditional middlew...

We demonstrate experimentally the tuning of complete photonic band gaps in patterned silicon nitride waveguides. Transmission measurements were performed using an ultrabroadband high-brightness white light laser continuum, extracting extinction ratios as low as 10 in the gap regions. Angle-resolved measurements show the perfect alignment of the gap around the G-J direction. © 2000 American Inst...

Packaging designers often come up with splendid design proposals, without being aware of technical, marketing or economical restrictions. This leads to infeasible proposals, so many packaging design projects fail. To bridge the gap between design and marketing, a tool has been developed that shows several designs to an extensive community. Designers now have the possibility to get feedback of t...
