This paper investigates thumb-index interaction on touch input devices, and more precisely the potential of two concurrent stroke gestures , i.e . in which fingers same hand concurrently draw one each. We present fundamental studies, using such for two-dimensional control, by drawing figures, other command activation, roughly sketching figures. Results give a first analysis user performance 35 ...

The research presented here focuses on the understanding of act drawing not only as a means restitution architectural survey but also considering modernization representation techniques. This must be considered first step for creation virtual environments capable offering advanced methodologies dissemination collected data. Expanding techniques that can referred to will necessary process, and o...

Popular method for assessment of final exam answer scripts in university and among the engineering drawing answer scripts based on absolute true or false judgment and assigning a single number or letter to answer of each problem cannot be so fair. To obtain a fair assessment method, we considered “imagination”, “accuracy”, “drawing” and “innovation” that are objectives of engineering dra...

A 60-year-old male presented with dyspnea and chest pain. He was referred with massive bulky mass. A mass in the left lung was observed using chest X-ray (Figures 1).  A computed tomography scan of the chest showed a mass on the left lung with complete lung collapse Figures 2 (A, B). The needle biopsy was performed and the case was diagnosed with solitary fibro...

a new method for increasing ldr in deep drawing is application of anti-lock braking system (abs) on blank holder. in this method, instead of applying a constant force on blank and control the metal flow, the abs system holds and releases the blank several times (20 to 50 times) which results increasing ldr. this study investigates the effect of different parameters of abs on improving the condi...
