Scheduling problems are NP – Hard combinatorial optimization problems, since many algorithms have been developed which offers new promising insights for solving resource allocation problems. Considering the problems faced in automobile repair shops, who sets the customer due dates of the car based on processing time, jobs already waiting for processing and mechanic available time. Also the work...

This report is a detailed review of the current data on the mechanic and gravitational sensitivity of osteoblasts and osteogenic precursor cells in vitro. It summarizes the numerous responses of cells with an osteoblastic phenotype and osteogenic precursor cells and especially their responses to the alteration of their mechanic or gravitational surroundings. The review also discusses the osteog...

Voluntary Exchange. If an airline mechanic gets paid $30,000 a year, it must be that the mechanic would rather have the money than the leisure time, while the airline would rather have the mechanic than have the money. Another example: apartment rentals. That is, price is bounded below by what the seller will accept: the supply price, and bounded above by what the buyer is willing to pay: the d...

In this paper, a two-dimensional computational model is proposed for predicting the initiation position and propagation path of subsurface crack of spur gear tooth flank. In order to simulate the contact of teeth, an equivalent model of two contacting cylinders is used. The problem is assumed to be under linear elastic fracture mechanic conditions and finite element method is used for numerical...

Depictions of scientific development in popular media carry significant influence over the way that the public envisions science as a process and as an institution. One such popular depiction of science is the “Tech Tree,” a common game mechanic in strategy videogames. This mechanic is often problematic, as in its most common form, the tech tree depicts a technologically deterministic view of s...

Three experiments explore how American (N = 102) and Egyptian (N = 73) preschoolers’ inferences about expertise are affected by an expert’s gender and occupation. Children viewed a nurse and a car mechanic in a gender stereotypical (female nurse, male mechanic) or counterstereotypical (female mechanic, male nurse) presentation and indicated who would know more about profession-related informati...

This study documents age trends, interrelations, and correlates of intellectual abilities in old and very old age (70-103 years) from the Berlin Aging Study (N = 516). Fourteen tests were used to assess 5 abilities: reasoning, memory, and perceptual speed from the mechanic (broad fluid) domain and knowledge and fluency from the pragmatic (broad crystallized) domain. Intellectual abilities had n...

Results He had Type II A aortic dissection with intimal tear at proximal region of the right coronary ostium. Mechanic aortic valve was normal function. Ascending aorta was replaced by using 26 mm Dacron tube graft between annulus of previous mechanic aortic valve and distal ascending aort by using hypothermic circulatory arrest and antegrade selective cerebral perfusion. An 8 mm dacron tube gr...

Level creation is a creative game-play exercise that resembles problem-posing, and has shown to be engaging and helpful for players to learn about the game’s core mechanic. However, in user-authoring environments, users often create levels without considering the game’s objective, or with entirely different objectives in mind, resulting in levels which fail to afford the core gameplay mechanic....
