Automatic handover between 3G and WLAN networks is typically done when the current network link is going down. In this paper, we explore another possibility: automatic handover to the network which has highest signal level, to ensure steadier connection and faster download speeds. The proposed solution for Nokia N900 device is modular and extensible. Routines to choose the network to connect to...

Terrence J. Sejnowski Howard Hughes Medical Institute UCSD and Salk Institute, San Diego, CA 92186-5800, USA Songbirds learn to imitate a tutor song through auditory and motor learning. We have developed a theoretical framework for song learning that accounts for response properties of neurons that have been observed in many of the nuclei that are involved in song learning. Specifically, we sug...

We present far ultraviolet spectra of a fast (∼ 300 km s) nonradiative shock in the Cygnus Loop supernova remnant. Our observations were performed with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, covering the wavelength range 905−1187 Å. The purpose of these observations was to estimate the degree of electron-ion equilibration by (1) examining the variation of O VI λλ1032, 1038...

The three sections of this paper illustrate the importance of rationalizing ISM theory and modeling with the observational information.

We develop a method for measuring the amount of insurance the portfolio of government liabilities provides against fiscal shocks, and apply it to postwar US data. We define fiscal shocks as surprises in defense spending. Our results indicate that the US federal government is partially hedged against wars and other surprise increases in defense expenditures. Seven percent of the total cost of de...

In recent years a lot of effort has been put into testing and improving the idea of a three-beam interferometer known as Optical Vortex Interferometer (OVI). Devices based on the idea of an OVI allow, among other things, measuring small rotation angles of the wave [1]. In this paper complex statistical analysis has been used for the results of the small-angle rotation wave measuring method. The...

A Nokia Lumia 1020 cellular phone (Microsoft Corp., Auckland, New Zealand) was configured to image the ova of Ascaris lumbricoides converged into a single field of view but on different focal planes. The phone was programmed to acquire images at different distances and, using public domain computer software, composite images were created that brought all the eggs into sharp focus. This proof of...

Nokia Research Center conducted a usability test for two XHTML Mobile Profile (MP) applications: a news application and an auction application. The goal of the test was to find out how XHTML MP components should and should not be used in order to build a usable mobile application. To compare different user interface solutions, both applications were designed in three different user interface st...
