Opportunistic communications have been recently proposed as a key strategy for offloading traffic from 3G/4G cellular networks, which is particularly beneficial in case of crowded areas where many users are interested in similar contents. To conserve energy, duty cycling schemes are typically applied, and therefore contacts between nodes may become intermittent and sporadic also in dense networ...

The study examined the relationship between type of non-psychotic diagnosis at time of hospitalization, pre-Navy non-psychotic condition, and paygrade for active duty, enlisted Navy personnel. The sample (N = 27,210) consisted of all hospitalized cases of active duty, enlisted Navy personnel from 1981 through 1984 with a nonpsychotic mental disorder as the primary diagnosis. Results indicated t...

In this paper we describe a system that uses patterns of eye blinks as a biometric. Each user chooses a personal blink pattern based on a song (for example “Jingle Bells”). To establish their identity, the user looks at the system’s camera and blinks to the cadence of their chosen song. Computer vision is used to detect the blinks and to compare the blinked cadence to a database of stored blink...

A simple odd number frequency divider with 50% duty cycle is presented. The odd number frequency divider consists of a general odd number counter and the proposed duty cycle trimming circuit. The duty cycle trimming circuit can output 50% duty cycle with only additional six transistors. A prototype divide-by-5 circuit with 50% duty cycle was implemented for a 500-Mb/s ∼ 5.6-Gb/s 1:10 CDR/DEMUX ...

Metris is a version of the Tetris game that uses a player’s musical response to control game performance. The game is driven by two factors: traditional game design and the player’s individual sense of music and sound. Metris uses tuning principles to determine relationships between pitch and the timbre of the sounds produced. These relationships are represented as bells synchronised with signi...

This paper considers the Greenspan/Summers/IMF (GSI) argument that the Asian way of doing business was the deep cause of the Asian crisis. The IMF reform programme for the crisis-affected Asian countries suggested they should abandon the Asian business model and adopt the US corporate model. The main findings are: a) contrary to GSI doctrine, poor corporate governance and lack of competition ar...

Color preference research has traditionally focused on summarising or explaining the color preferences of groups of people. Claims of universal patterns and trends in color preference have generally been based on group analyses, with little consideration of the individual. Initial investigation of this issue has revealed that, although patterns can be identified at the group level, individual d...

A novel wake-up receiver for wireless sensor networks is introduced. It operates with a modified medium access protocol (MAC), allowing low-energy consumption and practical latency. The ultra-low-power wake-up receiver operates with enhanced duty-cycled listening. The analysis of energy models of the duty-cycle-based communication is presented. All the WuRx blocks are studied to obey the duty-c...

Electron linacs in the 100 MeV to 25 GeV energy range have by now been in operation for periods ranging from one year to over 20 years. In 1951 the Mark III accelerator at Stanford became the first electron linac to exceed an energy of 100 MeV. Since then significant increases in maximum electron energy have been made by the h'Iark III (reaching an energy of 1 GeV in 1960) and SLAC (exceeding 2...
