Processors for Mobile Applications

Mobile processors form a large and very fast growing segment of semiconductor market. Although they are used in a great variety of embedded systems such as personal digital organizers (PDAs), smart cards, internet appliances, laptops, smart badges, cellular phones, wearable computers, and sensor networks, they share the common need for low power, code density, security, cost sensitivity and multimedia and communication processing

Fabrication and characterization of micro-porous ceramic membrane based on kaolin and alumina

Kaolin and α-alumina powders are used to synthesise microporous ceramics using starch as an organic pore-former, and phosphoric acid as an inorganic binder. This work has been carried out to further develop microporous ceramic materials based on alumina-kaolin for filtration purposes. The membranes are characterized using SEM, XRD, permeability, porosity, density, average pore size, chemical stability, shrinkage, and solvent permeation. The ceramics sintered at 1200°C, after being compacted at 14.7 MPa, exhibit porosity of about 32.2±3%. These ceramics show reasonably good permeability as well as mechanical strength. The average pore sizes of these supports found to be approximately between 0.5–1.5 µm and are hydrophilic in nature

Bi-modal Network Relationships in Online Health Networks

Several studies have examined online patient networks from a social network analytic perspective. Conventional methods of analysis of online networks rely on the mechanisms provided by the platform such as “friends†(Facebook), “followersâ€, “retweets†and “mentions†(Twitter) in order to identify network connections among users. Similar mechanisms have been incorporated into online patient portals as well. However, as an alternative approach, the interactions among the users in such online patient forums can also be used to identify their network connections. This study aims to provide a deeper understanding of the impact of selecting one approach over the other. We delineate the difference between network characteristics of users such as centrality derived from (1) network identified through the existing mechanism of followers and (2) network identified based on the interactions alone (participation in the same thread). This exploration of multiplexed networks provides an insight on how the network characteristics’ impact on the respective user’s popularity differs based on the two identification approaches. The data consists of Parkinson’s disease-related discussions and associated user characteristics collected from a popular online patient network
