Interface for an Ultra Large Tablet
نویسندگان
چکیده
In general, Personal Digital Assistant (PDA) devices are utilized for the purpose of reading, typing and playing games and etc. However, PDAs’ small screen size is not often convenience for users when they use it for a long period. A new device is implemented with 17 inch screen size and a touchpad at the back of the display to overcome this problem. Two different user studies have been conducted with the implemented device in order to comparing the performance of using the new device and the iPad through both objective measures and subjective measures. The experimental results show that the new device and the iPad have no significant difference in playing game but the new device is significantly slower than the iPad in typing a paragraph. Key words: Large iPad, Interface, game, typing, BackPad, 17 inch screen, users’ performance

Access control in ultra-large-scale systems using a data-centric middleware
The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between sub-systems is increased, achieving more scalable and dynamic access control system becomes an im...

متن کاملStability-indicating UFLC method for uncoupling and estimation of impurities in clopidogrel, aspirin and omeprazole in their tablet dosage form using PDA detection
In this paper a fast and novel stability-indicating ultra fast LC method for separation and estimation of impurities in clopidogrel and aspirin in their combined tablet dosage form and omeprazole was developed. The separation of USP related substances of clopidogrel (A, B and C), aspirin (D), omeprazole (A, B and C) and few other unknown impurities was detected by using ultra fast liquid chroma...
متن کاملStudy on the strengthening mechanisms and failure modes of the ultra-fine grained tri-modal Al5083-5wt. %B4C-Al2024 and Al5083-5 wt. %B4C-Al5083 composites
In this paper, the influence of Al2024 and Al5083 aluminum alloy coarse grains on mechanical properties and fracture mechanism of Al5083-B4C tri-modal composite has been discussed. Al5083 alloy powders with 5 wt. % of boron carbide were milled for 36 hours and 25 and 50 wt. % of coarse grain (CG) Al2024 and Al5083 powders were added to the milled powders and then hot press under argon atmospher...
