We investigate the details of Titan's interaction with Saturn's magnetosphere, which includes formation of an ionopause and its location and mass loading via ion pickup. We present some new interpretations of the Voyager 1 encounter results, not previously done by Hartle and coworkers [1]. Using arguments based on theory and observation we show that in the outer pickup region, ion pickup of H +...

In the last decade, there has been an increasing body of research in dynamic vehicle routing problems. This article surveys the subclass of those problems called dynamic pickup and delivery problems, in which objects or people have to be collected and delivered in real time. It discusses some general issues as well as solution strategies.

Recently, there is great interest in monolithically integrated free-space micro-optics using micromachining techniques [ 11. Monolithic integration of the whole micro-optical system can drastically reduce its size, weight, and cost. In addition, the expensive packaging process of individual optical elements can also be eliminated. An example of the newly micromachined integrated micro-optical s...

The double travelling salesman problem with multiple stacks (DTSPMS) is a pickup and delivery problem in which all pickups must be completed before any deliveries can be made. The problem originates from a real-life application where a 40 foot container (configured as 3 columns of 11 rows) is used to transport up to 33 pallets from a set of pickup customers to a set of delivery customers. The p...

Voyager 2 and Ulysses were at nearly the same latitude in the southern heliosphere at the beginning of 1999 and their radial separation was about 55 AU. The e ect of pickup ions should be profound at Voyager's position, especially, the deceleration of the solar wind ow. This unique opportunity allows us to investigate the e ect of pickup ions based on direct multi-spacecraft observations. The U...

We have developed an experimental 4K × 2K pixel progressive scan color camera system. This new camera system has a data rate of 297MHz pixel/sec and 60 frame/sec and we are sure that horizontal and vertical limiting resolution of 1500TVL (TV lines) can be achieved on a color monitor. Instead of the previous approach of improving resolution simply by increasing the pixel count in a imager, a nov...

We analyze a business model for e-supermarkets to enable multi-product sourcing capacity through co-opetition (collaborative competition). The logistics aspect of our approach is to design and execute a network system where ‘‘premium’’ goods are acquired from vendors at multiple locations in the supply network and delivered to customers. Our specific goals are to: (i) investigate the role of pr...

Aims. By reevaluating a 13-month stretch of Ulysses SWICS H pickup ion measurements near 5 AU close to the ecliptic right after the previous solar minimum, this paper presents a determination of the neutral interstellar H density at the solar wind termination shock and implications for the density and ionization degree of hydrogen in the LIC. Methods. The density of neutral interstellar hydroge...
