The main drawback of the rapidly evolving field of silicon photonics lies in the absence of efficient monolithically integrated radiation sources as a consequence of the indirect bandgap of Si and Ge. Relevant alternatives based on the hybrid combination of Si with optically active materials have to be technologically simple, temporally stable, and provide efficient coupling to the Si waveguide...

The present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. Performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. This new optimization concept is carried out for unbrac...

For slotted networks carrying full multi-media traac to work successfully, it is essential that connection setup and management is done well under all traac conditions. Major challenges remain with the current state of the technology, however, particularly on how one copes with traac bursts. Existing reservation-based networks do not allow the user to dynamically adjust his bandwidth requiremen...

• Restraining the notch effect in dowels significantly increases connection ductility. Post-elastic steel properties of strongly influence displacement capacity. Optimized detailing combined with an adequate allow to reach a high Constriction contact area plate has been observed. According Eurocode 8 moderate dissipative behaviour timber structures requires sufficient ductility critical regions...

In this paper, we present a study on Aloha and Slotted Aloha protocols for Underwater Sensor Networks (UWSN). Such simple random access protocols allow sensor nodes to communicate in UWSN. We present a simple mathematical analysis as well as simulations to show the performance of Aloha and Slotted Aloha in the acoustic environment. Our results show that long propagation delay of acoustic signal...

Balloon angioplasty of ostial left anterior descending coronary artery (LAD) lesions has been associated with a high rate of acute complications and late restenosis. Recently, coronary stenting has been proposed as an effective treatment modality for ostial LAD lesions. To evaluate the effects of stent design on the development of late restenosis, we retrospectively analyzed the efficacy of slo...
