The Internet Engineering Task Force has developed Mobile IP to handle mobility of Internet hosts at the network layer. Mobile IP, however, suffers from a number of drawbacks such as high handover latency, packet loss, and conflict with network security solutions. In this paper, we describe TraSH, a new Transport Layer Seamless Handover solution to mobility. TraSH utilizes multi-homing to achiev...

The outdoor service robot which we call OSR-01 is presently under development intending for cleaning up urban areas by means of collecting discarded trash such as PET bottles, cans, plastic bags and so on. We, in this paper, describe the architecture of OSR-01 consisting of hardwares such as sensors, a manipulator, driving wheels, etc. for searching for and picking up trash, and softwares such ...

The status of video cotton trash and cotton color measurement work at Southwestern Cotton Ginning Research Laboratory (SWCGRL) is presented. New accomplishments are in the areas of video measurement of absolute color in CIE XYZ and Hunter’s Rdab color spaces and improvements of bark trash type identification.

In Gucheng Lake, Jiangsu Province, China, randomly selected crabs were fed 2 diet types. Crab crude oil methyl ester analysis was performed using gas chromatography-mass spectrometry. Fatty acid compositions in the 3 edible parts of a crab - the hepatopancreas, gonad, and muscle - were analyzed. C16:1 and C18:2 were significantly higher in most commercial pellet feed-feeding crabs than in small...

Air pollution experienced by expanding urban areas is responsible for serious health effects and death for millions of people every year. Trash burning is a common disposal method in poor areas, yet it is uncontrolled in many countries, and its contribution to air pollution is unclear due to uncertainties in its emissions. Here we develop a new trash burning emission inventory for Mexico City b...

The local and regional impacts of open fires and trash burning on ground-level ozone (O3) and fine carbonaceous aerosols in the Mexico City Metropolitan Area (MCMA) and surrounding region during two high fire periods in March 2006 have been evaluated using WRFCHEM model. The model captured reasonably well the measurement-derived magnitude and temporal variation of the biomass burning organic ae...

Trash deposits in aquatic environments have a destructive effect on marine ecosystems and pose a long-term economic and environmental threat. Autonomous underwater vehicles (AUVs) could very well contribute to the solution of this problem by finding and eventually removing trash. A step towards this goal is the successful detection of trash in underwater environments. This paper evaluates a num...
