In this paper, a simple, efficient, and parameter free algorithm, DISCUR, is proposed to reconstruct curves from unorganized sample points. The proposed algorithm can reconstruct multiple simple curves that may be open, closed, and/or with sharp corners. The criteria for the curve reconstruction are based on two observations we have made concerning the(More)

Creativity is an important topic in design research. Attempts have been made to develop methods and tools that can help designers become more creative. Yet how and why creativity occurs is still unknown to researchers. In this paper, we propose a theoretical model for creative design. This theoretical model builds on two postulates: 1) design reasoning(More)
A retrospective review of 48 consecutive morbidly obese patients with urolithiasis who were treated successfully by endoscopic modalities over 3.5 years was performed. Of the 73 endoscopic procedures, 48 were ureteroscopic laser lithotripsy (UL), 4 were ureteroscopic basket extraction, and 21 were percutaneous nephrolithotripsy (PCNL). The patients' weight(More)
This paper presents the results of a study designed to compare the processes followed by practitioners of 9 three design methods: the algorithm of inventive problem solving, axiomatic design, and environment-based design. 10 Prior literature has postulated the complementary nature of these design methods, and in some cases, has provided 11 case studies of(More)
Graphical password is an authentication means alternative to textual password and biometric password. Graphical passwords are classified into two groups: picture based password and user-drawn based password. To pass the authentication, in the picture based graphical password, users have to choose right photos whereas in the user-drawn based graphical(More)
