Casimir Rack and Pinion
As the technological advances lead to miniaturization of mechanical devices, engineers face new challenges that are brought about by the fundamentally different rules that apply at small scales. One of the biggest problems in small machines is the excessive wear of the many surfaces that work in contact with each other, which severely constrains the durability of such machine parts. Here, a for...
متن کاملDetailed Vibration Analysis of Pinion Gear with Time- Frequency Methods
Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the Lead Center for NASA's scientific and technical information. The NASA STI Program Office provides ...
متن کاملFlank milling with flat end milling cutters
In this paper, we give a detailed mathematical understanding of flank milling with flat end cutters, which we use to develop a method for milling with such a cutter. This method slides the cutter along two rails, providing two points of contact on the surface.
متن کاملScheduling Coast Guard District Cutters
United States Coast Guard (USCG) districts schedule cutters 180 feet or less in length to weekly statuses (statuses is USCG jargon for assignments) from which they primarily respond to calls for search and rescue, law enforcement, and pollution control. The First Coast Guard District, based in Boston, has one of the largest scheduling problems: Each of 16 cutters is assigned weekly to one of si...
متن کاملA new class of genome rare cutters
Although significant efforts have been directed at developing efficient techniques for rare and super rare genome cutting, only limited success has been achieved. Here we propose a new approach to solve this problem. We demonstrate that peptide nucleic acid 'clamps' (bis-PNAs) bind strongly and sequence specifically to short homopyrimidine sites on lambda and yeast genomic DNAs. Such binding ef...
