Maxillo-facial surgery is a surgical field where surgical planning and navigation tools are commonly used but there is still a visualization gap among planned surgical activities and those in the operating room. We propose an Augmented Reality platform that includes a planning module and a drill guidance system. Some laboratory tests on 3D printed mandibles have been carried out in order to evaluate the system guidance uncertainty with different sets of fiducial points. The obtained mean value of guidance uncertainty has been of 1.37 mm when 2 anatomical points and 3 implanted screws were used and 1.43 mm when 5 anatomical points were used. The use of three fixed screws reduces the system mean guidance uncertainty and surgeons judged the augmented reality technology helpful in this kind of surgical procedures.

We developed a free form deformation application for an immersive environment in which users can interact freely using data gloves. To ensure better comfort and performances. we added the possibility of bimanual interaction in our environment. To investigate the actual gain obtained by this interaction technique, we designed an experimental protocol based on spatial input tasks. In our experiment. we asked our subjects to use only the dominant hand to achieve the different tasks or, oil the contrary, to use both hands. Comparison of users' performances - time and precision - shows that, Without proper training, executing a task using two hands can he more time consuming than using one hand. In fact, the degree of symmetry of the tasks performed with each hand seems to have a significant impact On Whether users take advantage of bimanual Possibilities. Our results also show that bimanual interaction can introduce proprioceptive Cues that can be of help to achieve more precision in the placement or selection only when proper visual information are missing,

With process variation becoming a growing concern in deep submicron technologies, the ability to efficiently obtain an accurate estimate of failure probability of SRAM components is becoming a central issue. In this paper we present a general methodology for a fast and accurate evaluation of the failure probability of memory designs. The proposed statistical method, which we call importance sampling through norm minimization principle, reduces the variance of the estimator to produce quick estimates. It builds upon the importance sampling, while using a novel norm minimization principle inspired by the classical theory of Large Deviations. Our method can be applied for a wide class of problems, and our illustrative examples are the data retention voltage and the read/write failure tradeoff for 6T SRAM in 32 nm technology. The method yields computational savings on the order of 10000x over the standard Monte Carlo approach in the context of failure probability estimation for SRAM considered in this paper.

Geometric design of sculptured surfaces and solids has been a major concern in recent developments in computer-aideddesign (CAD). A rational parametric cubics and bicubics-based CAD system has been developed in a micro environment. All geometric elements are stored in rational format, thus allowing creation of exact, uniform geometric databases for sculptured surfaces and solids. This paper presents an algorithm, based on the divergence theorem, for evaluating integral properties such as surface area, volume, centroid, and moments of inertia, of shapes bounded by rational parametric bicubic surfaces.

Protocol conformance test plays a necessary and important role in guaranteeing that broadband PLC (Power Line Communication) devices to meet the standards and achieve interoperability. A broadband PLC Conformance Testing System is designed based on TTCN-3 framework. The implementation scheme for conformance testing platform is proposed and the module mechanisms as well as key techniques are described. Test suite are designed according to broadband PLC testing requirements, and finally test cases are executed based on testing environment constructed. The work is of significance for promoting the broadband PLC standardization and interoperability.
