A multstatic frequency-modulated continuous wave (FMCW) radar system is under development for use in the control system of autonomous vehicles. The aim of the system, named Colarado, is the 3D location of obstacles in the surrounding environment. In this paper a laboratory prototype system version, the demonstrator, is described and current results are presented.

Performance tuning of applications for shared-memory multiprocessors is to a great extent concerned with removal of performance bottlenecks caused by communication among the processors. To simplify performance tuning, our approach has been to extend the hardware/software interface with powerful memory-control primitives in combination with compiler optimizations to remove communication bottlenecks in distributed shared-memory multiprocessors. Evaluations have shown that this combination can yield quite dramatic application performance improvements. This raises the fundamental question of how the hardware/software interface in future distributed shared-memory machines should be defined to serve as a good target for performance tuning of shared-memory programs, either automatically or by hand. An approach along those lines is discussed.

We present a novel technique CLIP for optimizing both theheight and width of CMOS cell layouts in the two-dimensional (2-D) style. CLIP is based on integer-linear programming (ILP) and proceeds in two stages: First, an ILP model is used to determine a 2-D layout of minimum width W cell . Then, another model generatesa 2-D layout that has width W cell and requires a minimumnumber of routing tracks. Run times are in seconds for circuitswith up to 16 transistors. For larger circuits, we extend CLIP to ahierarchical method HCLIP that places series-connected transistorscontiguously. This reduces run times by up to three orders ofmagnitude, and still yields optimal results in over 80% of cases.
We address the problem of CMOS cell width minimization in the general two-dimensional (2-D) layout style and propose a novel technique based on integer linear programming (ILP) to solve it exactly. We formulate a 0-1 ...

We address the problem of CMOS cell width minimization in the general two-dimensional (2-D) layout style and propose a novel technique based on integer linear programming (ILP) to solve it exactly. We formulate a 0-1 ILP model whose solution minimizes cell width along with the routing complexity across the diffusion rows. We present experimental results that evaluate the performance of two ILP solvers that have very different solution methods, and assess the effect of the number of rows on cell width. Run-times for optimal layouts are in seconds for cells with up to 20 transistors. For larger cells, we propose a practical circuit pre-processing scheme that dramatically reduces the run time with little or no loss in optimality.

This book constitutes the refereed proceedings of the 7th International Conference on Articulated Motion and Deformable Objects, AMDO 2012, held in Port d'Andratx, Mallorca, Spain, in July 2012.
The 27 papers presented were carefully reviewed and selected from 44 submissions. The volume also contains one full paper length invited talk. The conference dealt with the following topics: advanced computer graphics (human modeling and animation); human motion (analysis, tracking, 3D reconstruction and recognition); multimodal user interaction and applications; and affective interfaces (recognition and interpretation of emotions, ECAs -- embodied conversational agents in HCI).
