For able-bodied people within the art and design discipline, access to computeraideddesign (CAD) and visual graphic interface is a well-defined iterative process. However for non-sighted people or people with impaired vision, this is a difficult process to facilitate. Often this issue excludes and/or limits access for people with vision impairments to fully utilise CAD systems, web interface, and any other visually led interface which mainly communicates through graphical or pictorial cues and image-based metaphors. This paper presents an ongoing inclusively designed multimodal system. Whereby the use of digitally adapted haptic technology is explored via a clinically established and valid fine motor skills test: 'Wade's Nine-Hole-Peg- Test' (NHPT). Particular attention is paid to assess whether non-sighted participants can gain a level of speed and efficacy of NHPT task by using the haptic technology together with their own tacit haptic perceptions compared to a subject group of healthy sighted participants. The results indicate better performance of non-sighted participants when compared to the sighted, while also showing that implemented multimodal cues assist the performance of both participant groups based on insertion time. Given these results, future work will focus on analysing collision data from haptic insertion of the pegs in holes to compare performance based on recorded error. Additionally, these findings will be used towards providing tools for more inclusive interfaces to be used in pedagogic practices.

Medical imaging techniques offer novel visualization and analysis methods of the vocal folds during phonation and automatic computation of indices aiding the phoniatrist in a more precise diagnosis of voice disorders. The aim of this study is to apply computer vision algorithms for qualitative and quantitative analysis of vocal folds' vibrations. Videostroboscopic examinations of the larynx were carried out for 30 patients. Image pre-processing and image segmentation algorithms were applied to compute the glottis area during phonation. The glottovibrograms which are spatio-temporal visualizations of the vibrating vocal folds were also built. The proposed indices allow for a quantitative and comparative analysis of normal and disordered phonatory processes. The conducted pilot study has confirmed the validity of the computeraided imaging methods for the qualitative and quantitative analysis of the videostroboscopic images of the phonatory motions of the vocal folds.

First year design courses in the Mechanical Engineering Curriculum typically intend to familiarize students with the use of a CAD software package in preparation for future design or CAE coursework. Learning outcomes of these introductory courses often focus on the mechanics of generating the models using the software of choice. While most students find CAD modeling interesting, the focus on learning the software, as imparted in these traditional first or second semester CAD courses, often does not allow experiencing the role of the software tools within the design process, becoming an exercise in modeling rather than design. At the University of Maine's Brunswick Engineering Program (BEP), an engineering studio course has been developed that shifts the focus from learning the software mechanics to learning and experiencing the engineering design process;CAD software skills are conveyed "in passing", with just-in-time instruction to support students in completing the design portion of a common integrated project. Survey results after two iterations of the course indicate high levels of perceived learning and student satisfaction. This is supported by the formative and summative course assessment, and initial results of a post-test Purdue Spatial Visualization Test - Rotations.

SISPAD and Technology computeraideddesign (TCAD) are relatively new compared to semiconductors. The history of using computers to design technology dates to the 60's and the first conferences devoted to the field started in the late 70's. As the field matured, the various conferences combined. TCAD has both benefited from and contributed to Moore's Law. New frontiers in nano-devices, sensors, reliability, and alternate materials are still active areas of research.

One of the most valuable problems in control systems design is fast and accurate numerical simulation. The developer of a particular simulation system should choose the most efficient numerical integration method, taking into account features of the hardware platform. Today personal computers became a powerful tool for engineering and scientific applications, but have some disadvantages comparing to modern supercomputers: lack of parallelism, scalar processors and special problem requirements to effective program execution on GPU are the first problems that the simulation software faces. In this paper, we propose an efficient semi-implicit extrapolation D-method that shows the best performance on the modern personal computer than the other studied integration methods, and is suitable for embedded platforms as well. A brief description of the method is given, and experimental results are presented.

In a system-on-a-chip (SOC) design, several to hundreds of design blocks or intellectual properties (IPs) are integrated to form a complex function. Prior to verify the functionality of the integrated IPs, it is very important to ensure the correctness of the port connections among these IPs. This paper addresses the problem of verification on port connections while IPs are integrated into a larger block or a system, and presents a new connection model and the corresponding error model for port connections. An algorithm providing the minimum pattern set and a general verification flow used to verify port connections are also proposed.
