This paper presents a novel approach to the control and management of ATM networks, by allowing di erent control architectures to be operational within the same network, and on the same switch. The resources available on an ATM switch are divided into switchlets, each of which encapsulates a subset of the physical ATM switch resources. A set of switchlets on di erent ATM switches combine to for...

In this course so far, we have studied two kinds of links that connect computers together: a point-to-point link, typically constructed from a wire, and a shared medium such as radio, for which we developed frequency division multiplexing. In a point-to-point link, the sharing of the link can be done by the switch to which the link is connected. In contrast, when using a shared medium to connec...

MicroRNAs (miRNAs) are small, noncoding RNAs that play an important role in many key biological processes, including development, cell differentiation, the cell cycle and apoptosis, as central post-transcriptional regulators of gene expression. Recent studies have shown that miRNAs can act as oncogenes and tumor suppressors depending on the context. The present work focuses on the physiological...

In some circumstances, people interact with a virtual keyboard by triggering a binary switch to guide a moving cursor to target characters or items. Such switch keyboards are commonly used by patients with severely restricted motor capabilities. Typing with such systems enables patients to interact with colleagues, but it is slow and error prone. We develop a methodology that can automate an im...

Cellular plasticity refers, among others, to the capability of differentiated cells to switch the differentiation process and acquire new fates. One way by which plant cell plasticity is manifested is through de novo regeneration of organs from somatic differentiated cells in an ectopic location. However, switching the developmental program of adult cells prior to organ regeneration is difficul...

Ka band multimedia satellite networks have the potential to bring two-way broadband services directly to the end-user while providing ubiquitous global connectivity with Quality-of-Service (QoS) guarantees. TRW’s satellite network architecture design process involves Demand, Design and Financial modeling. The main Design challenge is to balance the delivery of network services and QoS demanded ...
