Efficient and effective cage generation by region decomposition
Authors: Xian Chuhua , Li Guiqing , Xiong Yunhui 
Published: April 2014

AbstractCage‐based deformation has become a popular method for shape deformation in computer graphics and animation. To edit a shape first requires a cage to be built to envelop the target model which is a tedious work by manual approaches. In this paper, we develop an automatic method to generate the cage for a model using voxelization based decomposition. We first voxelize the input model, and then use the seed filling algorithm to group the inner voxels. By dilating the inner voxel groups, we decompose the model into broad regions and narrow regions. Then we construct partial cages using different strategies and unite them to get a cage. Experiment results demonstrate that our method is effective, efficient as well as robust to model transformation. Copyright © 2014 John Wiley & Sons, Ltd.
Generating a multiplicity of policies for agent steering in crowd simulation
Authors: Boatright Cory D. , Kapadia Mubbasir , Shapira Jennie M. , Badler Norman I. 
Published: April 2014

AbstractPedestrian steering algorithms range from completely procedural to entirely data‐driven, but the former grossly generalize across possible human behaviors and suffer computationally, whereas the latter are limited by the burden of ever‐increasing data samples. Our approach seeks the balanced middle ground by deriving a collection of machine‐learned policies based on the behavior of a procedural steering algorithm through the decomposition of the space of possible steering scenarios into steering contexts. The resulting algorithm scales well in the number of contexts, the use of new data sets to create new policies, and in the number of controlled agents as the policies become a simple evaluation of the rules asserted by the machine‐learning process. We also explore the use of synthetic data from an “oracle algorithm” that serves as an as‐needed source of samples, which can be stochastically polled for effective coverage. We observe that our approach produces pedestrian steering similar to that of the oracle steering algorithm, but with a significant performance boost. Runtime was reduced from hours under the oracle algorithm with 10 agents to on the order of 10 frames per second (FPS) with 3000 agents. We also analyze the nature of collisions in such a framework with no explicit collision avoidance. Copyright © 2014 John Wiley & Sons, Ltd.

Design of reduced complexity feedback precoding for MIMO‐OFDM
Authors: Ghirmai Tadesse 
Published: April 2014

SummaryBeamforming technique is applied to significantly increase the performance of a MIMO system, if the channel information (CI) of the communication system is available at the transmitter. For the transmitter to obtain the entire CI, however, a considerable reverse‐link bandwidth is required. To save the bandwidth, a limited‐rate closed‐loop system, therefore, uses a predetermined codebook which is derived from the CI. The codebook consists of a finite number of precoders out of which the index of the best one is transmitted from the receiver to the transmitter using only a few bits saving substantial bandwidth. However, the amount of bits that need to be fed back can still be significantly large for MIMO‐OFDM systems when the precoding matrix index (PMI) for each subcarrier should be transmitted. Such per‐subcarrier precoding scheme has high feedback overhead and also incurs huge computational cost to determine the best PMI for each subcarrier. We, therefore, propose a per‐band precoding scheme that precodes a band (group) of subcarriers by only one precoder. More importantly, we develop, for the proposed per‐band scheme, reduced‐complexity precoding selection methods that lead to the design of efficient receivers. The effectiveness of the proposed scheme is investigated through computer simulations. Copyright © 2014 John Wiley & Sons, Ltd.
Development of Metal Cyanurates: The Example of Barium Cyanurate (BCY)
Authors: Kalmutzki Markus , Ströbele Markus , Bettinger Holger F. , Meyer H.‐Jürgen 
Published: April 2014

AbstractMetal cyanurate compounds were prepared by means of solid‐state metathesis reactions between a metal halide and an alkali cyanurate. Following this procedure, a mixture of BaCl2 and K(OCN) was heated in a fused silica tube at 575 °C to yield highly crystalline barium cyanurate. This reaction was analyzed by differential scanning calorimetry (DSC) measurements and involves a cyclotrimerization of cyanate ions to yield the cyclic cyanurate (O3C3N3)3– ion. The crystal structure of Ba3(O3C3N3)2 was refined by single‐crystal X‐ray diffraction, and the presence of cyanurate was verified by infrared spectroscopy.
