#IJSRD What is SAP Testing?

The SAP (System Applications Products) testing is same as software application manual testing but here the applications are the SAP R/3 (it is an ERP system) and Enterprise portal. So, whenever you get a change in R/3 and Portal, you need to come up with test cases for the new functionality and test the changes in the application. The SAP tester needs common testing mind with SAP tools knowledge like HR, SD and CRM etc will help in understanding the system and testing the applications.

New 3-D Printer Makes Soft Interactive Objects #ijsrd

A new type of 3-D printer can turn yarn into soft, cuddly objects. 3-D printingtypically uses metals and plastics, although researchers are also using them to make food stuff, tissue, and body parts. Researchers at Carnegie Mellon University who designed the new printer say they wanted to extend 3-D printing to a new class of materials for making objects that people would interact with.

The device is a kind of printer-sewing machine hybrid. It takes designs from a computer and converts them into 3-D objects using a loose felt material. The resulting objects are similar to hand-knitted versions, said CMU computer science professor Scott Hudson in a press release. Hudson developed the new printer with Disney Research support, and presented it at the ACM CHI Conference on Human Factors in Computing Systems.

Most common low-end 3-D printers are based on Fused Deposition Modeling, a process in which melted plastic is extruded to create objects layer by layer. The felting printer works in a similar fashion, but emits yarn instead of melted plastic. A barbed felting needle at the printer head repeatedly pierces the yarn, entangling new fibers into the yarn layers below and bonding the layers together.
