A novel model of grid cells (GCs) to place cells (PCs) based on radial basis function network (RBFN) is proposed. The connection between multi-scale GCs and a PC is established through RBFN. For each PC, it is associated with a learned RBFN. During vehicle's space exploration, PCs and RBFNs are recruited flexibly after analysing the firing status of the existing PCs, and the transformation from GCs...
In this paper, a CMAC (cerebellar model articulation controller) neural network application on fault diagnosis of automobile automatic transmission system is proposed. Firstly, we build a CMAC neural network based diagnosis system with different coding scheme depending on the fault types. Secondly, the fault patterns, obtained from the China scholar's technical data, would be used to train the CMAC...
With fast speed and reliable capability of depth recovery, two-frequency phase measuring profilometry (PMP) is widely used for reconstructing 3-D surface. However, it suffers from random noise when the number of patterns is less. In this paper, we propose a hybrid pattern coding scheme which embeds Gray coding patterns into high-frequency PMP patterns through amplitude modulation. From captured modulated...
A Depth Template based 2D-to-3D Video Conversion and Coding system (DTVCC) is proposed by this paper. In DTVCC, triangle meshes are exploited to describe depth template for scenes in 2D video, an interactive system is designed to generate reliable depth template, depth map can be automatically reconstructed based on the depth template and 2D video frame pixels information, and the generated 3D video...
The purpose of this study was to evaluate the effectiveness of using procedural scaffoldings to enhance group discourse levels in a paper-plus-smart phone learning context. Sixty undergraduate and graduate students enrolled at a four-year university in southern Taiwan participated in this experimental study. All participants used built-in camera smart phones to learn new knowledge by scanning QR codes...
A reliable, energy-efficient on-chip interconnection network employing low-swing signaling can be designed by incorporating error-correcting code. Orthogonal Latin Square Code (OLSC) can protect the interconnection against transient errors, while also lowering energy consumption. When applied to a 64-bit link using a 45-nm CMOS technology with low-swing signaling, OLSC provided up to 55% energy reduction,...
The ultra-wideband (UWB) wireless technology is a crucial technique. Pulse position modulation with time hopping (PPM-TH) is one of the basic UWB modulation methods. In this paper, we study the traditional UWB and time reversal (TR) UWB performance in the PPM-TH system respectively. Although the performance of TR UWB is better than normal UWB, the Bit Error Rate (BER) is high when the noise is large...
There has recently been much interest in stream processing, both in industry (Cell, Storm series, NVIDIA G80, AMD FIRESTREAM) and academia (IMAGINE). Some researchers have accelerated a lot of applications in media processing, scientific computing and signal processing with a special programming style called stream programming. This paper presents a framework to program DSP with this special programming...
Real-time encoding of high-definition H.264 video is a challenge to current embedded programmable processors. Emerging stream processing methods supported by most GPUs and programmable processors provide a powerful mechanism to achieve surprising high performance in media/signal processing, which bring an opportunity to deal with this challenge. However, traditional serial CAVLC has highly input-dependent...
This paper presents a traffic signal control method based on ??large phase?? to solve the problem of traffic signal control. And a traffic signal control method using fuzzy system and genetic algorithm (GA) for city single-intersection is studied. The results of simulation indicate that the method can improve control effect and reduce computational cost.
Reducing program size is a critical issue in many embedded systems which require more functionalities without increasing the memory size. One of the approaches is to adopt a mixed-width instruction set architecture (ISA) which usually has an instruction set in general formats (usually 32-bit long) as normal instruction set and an instruction set in shorter format(usually 16-bit long) with limited...
Polyphase codes have a large mainlobe-to-sidelobe ratio in matched filter processing. However, the conventional matched filter processing of polyphase codes suffer severe signal loss in performance under large Doppler environment. The basic approach for overcoming the Doppler effect is to use a bank of Doppler-matched filters. Each of the Doppler-matched filters is designed to match a different Doppler...
In this paper, a weighted joint prediction mode is proposed. It not only compares the motion prediction and disparity prediction, but also compares the motion prediction, disparity prediction and the weighted joint prediction. Then, the prediction mode which leads the least prediction distortion is chosen as inter prediction. Experimental results show that the proposed encoding scheme can solve the...
