the term usability refers to a special index for success of an operating system. this study aimed to determine the reliability and validity of the software usability measurements inventory (sumi) questionnaire as one of the valid and common questionnaires about usability evaluation. the back translation method was used to translate the questionnaire from english to persian back to english. more...

It is remarkable that the pathological state of human soft tissues highly correlates with static and low-frequency mechanical properties, particularly shear elasticity (e.g., Sumi, 2005d). Accordingly, we have been developing ultrasonic (US)-strain-measurement-based onedimensional (1D) (Sumi et al., 1993, 1995a, 2010f; Sumi, 1999b, 2005d, 2008a, 2010d; Sumi & Matsuzawa, 2007b), 2D (Sumi et al.,...

PURPOSE To validate the Sumi Visual Disability Questionnaire (Sumi VDQ) to estimate visual disability in glaucoma patients using Rasch analysis. METHODS A total of 162 glaucoma patients underwent visual field (VF) testing in both eyes (Humphrey 24-2 Swedish Interactive Threshold Algorithm [SITA] standard program). The binocular VF was then calculated using the integrated VF (IVF) method. Visu...

Introduction This sketch presents a method for real-time 3D Sumi-e rendering. Sumi-e is the one of representative art forms of the Black ink painting in Korea, Japan and China. Most of researches about Sumi-e paintings in NPR (Non-Photorealistic Rendering) have focused on 2D or 2.5D Sumi-e brushwork simulation. We suggest a new automated rendering system for 3D image of Sumi-e painting. The fol...

Oriental ink painting, called Sumi-e, is one of the most distinctive painting styles and has attracted artists around the world. Major challenges in Sumi-e simulation are to abstract complex scene information and reproduce smooth and natural brush strokes. To automatically generate such strokes, we propose to model the brush as a reinforcement learning agent, and let the agent learn the desired...

This book offers a comprehensive description of the phonetic and phonological features of Sumi, a Tibeto-Burman language of Nagaland, North-east India. It represents the first in-depth investigation of the acoustic phonetics and phonology of tone in Sumi, and is one of the first extensive acoustic descriptions of a language of Nagaland. The book describes the segmental phonology, syllable struc...

Lifelong User Modelling (LUM) is a long-term vision which is a critical element in achieving lifelong personalized learning. One of the key factors for enabling LUM is making the user models scrutable, a feature used for allowing users to inspect and alter the modelling process. A Scrutable User Modelling Infrastructure (SUMI) is proposed in this paper, which attempts to include in the LUM pict...

Brushwork and ink dispersion make it difficult to render 3D common objects in the style of sumi-e painting. We use sphere mapping with brush texture and an image processing techniques to simulate brushstrokes and ink dispersion. The whole process is implemented in shaders running on Graphics Process Unit (GPU) that allows fast and highquality rendering 3D polygonal models in the style of sumi-e...

A Scrutable User Modelling Infrastructure (SUMI) is proposed in this paper, which focuses on three key Lifelong User Modelling (LUM) requirements: interoperability, scrutability and privacy. SUMI attempts to enrich the LUM vision by examining two unexplored “pieces of the puzzle”: the social e-networking and e-commerce domains. SUMI allows users to gather their various (lifelong) models which t...
