GATES: What a great era: computers, microchips, browsers, automation, and worldwide windows. FEYNMAN: Don’t forget quantum physics. Don’t forget rubber gaskets. Don’t forget bongo drums. GATES: Quantum physics helps us develop computer networks but gaskets and bongo drums? This is difficult, very difficult, maybe even macrodifficult to understand. FEYNMAN: Inferior rubber gaskets and greed led ...

world, and the anticipated decommissioning of facilities will generate many more drums. Currently, in compliance with federal regulations, waste storage facilities at U.S. Department of Energy (DOE) sites are inspected manually for degradation and to verify inventories. An Intelligent Mobile Sensing System (IMSS) has been developed for the automated inspection of radioactive and hazardous waste...

Assay of the radioactive content of waste drums is important for inventory and waste disposal purposes. The sampling of the drum content is a difficult, time and labor consuming procedure, involving special radiation protection considerations. On the other hand the characterization of waste drums containing radioactivity by measuring the drum as a whole (without opening) offers overall simplici...

This study analysed factors influencing food security status of female headed farm households in Abia state, Nigeria. Multistage random sampling technique was employed in selecting 240 female headed farm households from whom data were collected using structured questionnaire. Data collected were analyzed using descriptive statistics, food security indices and probit regression technique. Result...

This paper presents an automatic description system of drum sounds for real-world musical audio signals. Our system can represent onset times and names of drums by means of drum descriptors defined in the context of MPEG-7. For their automatic description, drum sounds must be identified in such polyphonic signals. The problem is that acoustic features of drum sounds vary with each musical piece...

The motion of binary particles in three horizontal rotating drums with continuous rotational speed changes was studied based on the Discrete Element Method (DEM). Different simulation conditions were compared between two circular and an elliptical drum using same number physical properties for drums, at a series from 0.01 to 21.9 rad/s. By varying speed, four flow regimes produced simulation. F...

Abstract The article notes that the existing mechanical drive of vertical spindle drums in cotton harvester is complex, with uncovered multi-stage gear transmissions create a strong noise, and engagements do not occur throughout height tooth. first left drum particularly as movement from apparatus gearbox transmitted through six engagements. Open gears quickly wear out, which disrupts chessboar...

Historically, scientists have developed software programs with limited resources and a strong focus on algorithms to generate scientific results and verify their approaches. With the rapid growth of hardware power, computer networks, and progress in software engineering, this brings a new challenge in scientific software development: how can scientists move from the development on the “algorith...
