This paper looks at the motivation for simulating painting directly on 3D objects, and investigates the main issues faced by such systems. These issues include the provision of natural user interfaces, the reproduction of realistic brush effects and the surface parameterization for texture mapping so that the results of the painting can be stored on texture maps. The paper further investigates ...

Because of the scarcity of observational data, existing estimates of the heat and water budgets of the Persian Gulf are rather uncertain. This uncertainty leaves open the fundamental question ofwhether this water body is a net heat source or a net heat sink to the atmosphere. Previous regional modeling studies either used specified surface fluxes to simulate the hydrodynamics of the Gulf or pre...

BACKGROUND During the 1990-1991 Gulf War, approximately 700,000 U.S. troops were deployed to the Persian Gulf theater of operations. Of that number, approximately 100,000 have presented medical complaints through various registry and examination programs. OBJECTIVES Widespread symptomatic illness without defining physical features has been reported among veterans of the 1991 Gulf War. We asce...

We realize a painting system that imitates painting on real objects in the real world. Many studies have proposed methods of painting simulation on 2D canvas, and the quality of such methods is improving. However, painting on 3D objects is not easy using conventional input devices such as a mouse or graphics tablet with 2D display. We solved this problem by providing a ToolDevice in a mixed rea...

Brain-computer interfaces (BCIs) enable paralyzed patients to communicate; however, up to date, no creative expression was possible. The current study investigated the accuracy and user-friendliness of P300-Brain Painting, a new BCI application developed to paint pictures using brain activity only. Two different versions of the P300-Brain Painting application were tested: A colored matrix teste...

It is difficult for consumers to judge whether a painting or poster would fit well in their rooms without actually mounting the painting on the wall. A solution is proposed to allow users to their DROID mobile phones to preview what the painting looks like on the wall using the phone’s camera and its screen. The system is a marker-based, augmented-reality system that can place paintings on wall...

The reporting of pain was compared for U.K. Persian Gulf War veterans, veterans from the Bosnian conflict, and personnel employed in the military at the time of the Persian Gulf War but not deployed (era comparison group). Pain manikins were used to assess the prevalence of the reporting of pain in different body sites and the prevalence of the reporting of widespread pain, in relation to compa...

OBJECTIVE The most commonly used instrument for the research and treatment of excessive internet use is Young's Internet Addiction Test (IAT). While the IAT has been translated to several languages (including Persian) and has demonstrated good psychometric properties across several independent studies, there is still a room for alternative assessment instruments. This study reports a validation...

The Indo-Persian state secretary has occupied center stage in the emerging discourse on bureaucracy, administration and the political formation of the Mughal state. The status and role of the munsh? (the IndoPersian state secretary) within the Mughal bureaucratic structure in 17th and 18th century have formed the basis of recent historical analysis. Scholarship on the Indo-Persian munsh? have b...

Finding an appropriate dataset for natural language processing applications is one of the main challenges for researches of this field. This issue is more problematic in Non-Latin languages especially Persian language. Access to an appropriate dataset that can be used in development of practical programs in language processing field, helps us to validate the obtained results and provide the fea...
