This paper research of productivity and work organization were investigated of a group made of five workers (two cutters, two tractor drivers and one cutter-inspector) and a team leader. The teamwas equipped with two tractors and three chain saws. The research was carried out in the area of management unit – Ju`na Krndija Kutjeva~ka, at an altitude ranging between 550 m and 750 m in a 55-year b...

Bilateral asymmetry of the paired claws of the lobster Homarus americanus is determined during the fourth and fifth juvenile stages by differential reflex activity; the side with the greater activity becomes the crusher while the contralateral side becomes the cutter. Juvenile lobsters reared during this critical period with a substratum that could not be grasped or with reduced input from pred...

This paper presents a three-component fixed dynamometer based on a strain gauge, which reduces output errors produced by the cutting force imposed on different milling positions of the workpiece. A reformative structure of tri-layer cross beams is proposed, sensitive areas were selected, and corresponding measuring circuits were arranged to decrease the inaccuracy brought about by positional va...

This paper presents a complete procedure for tool path planning and blade machining in 5-axis manufacturing. The actual cutting contact and cutter locations can be determined by lead and tilt angles. The tool path generation is implemented by piecewise curved approximation and chordal deviation detection. An application about drive surface method promotes flexibility of tool control and stabili...

In a nutshell, 21st century regionalism is not primarily about preferential market access as was the case for 20th century regionalism; it is about disciplines that underpin the tradeinvestment-service nexus. This means that 21st century regionalism is driven by a different set of political economy forces; the basic bargain is “foreign factories for domestic reforms” – not “exchange of market a...

This is the authors version of the work. CHI’15 , April 18–23, 2015, Seoul, Korea. Workshop Exploring the Challenges of Making Data Physical Abstract In this paper, we relate the iterative fabrication of a physical Bertin Matrix. Jacques Bertin designed and refined such devices over 10 years (1970–1980) and five iterations of what he called Dominos 1–5. For the purpose of an exhibit dedicated t...

We propose a method to engineer the genome of bacteriophages to increase their effectiveness as antibacterial agents. Specifically, we exploit the redundancy of the triplet code to design genomes that avoid restriction sites while producing the same proteins as wild-type phages. We give an efficient algorithm to minimize the number of restriction sites against sets of cutter sequences, and demo...

mowing. It is run along the ground on one large wheel which is f ree of the motor operat ing the cutter bar. I t can be tilted to cut up or down slopes and can be pivoted sharply in any direction. It has been found part icularly valuable for cutting around trees, boulders, t raps, creek-bottoms, and other golf course obstructions which formerly required hand cutt ing. The motor scythe, powered ...

Industrial robots are used in a great variety of applications for handling, welding and milling operations. They represent a cost-saving and flexible alternative for machining applications. A reduced pose and path accuracy, especially under process force load due to the high mechanical compliance, restrict the use of industrial robots for further machining applications. In this paper a method i...
