Bending process is one of the most significant fields of application of sheet metal die. In bending process, it is quite vital that the product should have the desired angle. Furthermore, in order to obtain the desired angle in the bent parts, spring-go and spring-back amounts must be known. In this study, 30o, 60o and 90o bending processes were applied to S235JR (1.0038) sheet metal having 3, ...

A number of studies and researches have been conducted on Virtual Surgery Planning. More specifically, topics on interactive virtual surgery using haptic device have been discussed in [1][2] and so on. Due to the nature of high demand in physical accuracy, many researchers adapted Finite Element Method(FEM) for the simulation. In this paper, I propose simplified massspring model for the interac...

The string pendulum consists of a mass attached to the end of an inextensible string which is fastened to a support. Applying an external forcing to the pendulum’s support is motivated by understanding the behavior of suspension bridges or of tethered structures during earthquakes. The forced string pendulum can go from taut to slack states and vice versa, and is capable of exhibiting interesti...

Cool-season (northern) and warm-season (southern) grasses are grown in Arkansas. Cool-season grasses grow best in the spring and fall and less actively in the summer. They stay reasonably green in the winter. Tall fescue (Festuca arundi­ nacea) is the most commonly grown cool-season grass in Arkansas. Warmseason grasses are slow to green up in the spring, grow best in the summer and go dormant ...

The interpretation of microarray and other high-throughput data is highly dependent on the biological context of experiments. However, standard analysis packages are poor at simultaneously presenting both the array and related bioinformatic data. We have addressed this challenge by developing a system springScape based on 'spring embedding' and an 'information landscape' allowing several relate...

Infratemporal fossa injuries are uncommon and often go undetected presenting later with complications. We present a case of an infratemporal fossa penetrating injury with a ball point spring following a vehicular accident. Post-traumatic trismus even following supposedly trivial injury in the area should raise suspicion of possible injury in this location.
