A TFT-PIN array substrate and an assembly structure for a flat-panel x-ray detector are provided to overcome the problem that the conventional scintillator substrate and TFT-PIN array substrate are neither penetrated by UV-light nor assembled by UV curable LOCA. The metal layer of the PIN photodiode of the TFT-PIN array substrate is perforated to have at least one hole, whereby UV-light can pass through the TFT-PIN array substrate to cure UV curable LOCA. Therefore, UV curable LOCA can be used as an adhesive layer in the assembly structure of a scintillator substrate and a TFT-PIN array substrate to promote the detective quantum efficiency and image quality of a flat-panel X-Ray detector.

In this paper, we present a high-quality image authentication scheme based on absolute moment block truncation coding. In the proposed scheme, we use the parity of the bitmap (BM) to generate the authentication code for each compressed image block. Data hiding is used to authenticate whether the content has been altered or not. For image authentication, we embed the authentication code to quantization levels of each image block compressed by absolute moment block truncation coding (AMBTC) which will be altered when the host image is manipulated. The embedding position is generated by a pseudo-random number generator for security concerned. Besides, to improve the detection ability we use a hierarchical structure to ensure the accuracy of tamper localization. A watermarked image can be precisely inspected whether it has been tampered intentionally or incautiously by checking the extracted watermark. Experimental results demonstrated that the proposed scheme achieved high-quality embedded images and good detection accuracy, with stable performance and high expansibility. Performance comparisons with other block-based data hiding schemes are provided to demonstrate the superiority of the proposed scheme.

Most algorithmic composition system is implemented based on the input of music parameters, which needs professional music and technology training to complete the automated composition. This paper proposed an innovated way called Geographic and Meteorologic Data Sonification System (GMDSS), to perform the data mappings into music for various devices such as hand phone or other hand-hold devices, and the driver can retrieve the environment information in real time to let people concentrate on driving without the need of paying attention to the long-term complicated data visualization. The mapping relationship between geographic/meteorologic data and music features is discussed, and the result shows the implementation of GIS and weather data which can compose the proper correspondent music accordingly.

Random Pattern Generation for Post-Silicon Validation of DDR3 SDRAM

Due to the demand of pursuing a main memory with larger data bandwidth, higher data density, and lower power, the specification of DRAM has been constantly evolved in the past decade. The new DRAM specifications support multiple operating modes with multiple timing settings. It then becomes computationally infeasible to exhaustively validate all the combinations of different operating modes, timing settings and address/data with pure simulation before silicon. In this paper, we propose a framework to generate proper random patterns for validating a newly designed DDR3 SDRAM based on its first silicon chips. The proposed framework needs to not only guarantee the correctness of the generated patterns according to the state diagram and timing constraints defined in the specification but also provide the flexibility of exploring various design corners for the targeted DDR3 SDRAM. We will also show some successful silicon-validation cases of applying the proposed framework to identify the design errors based on real DDR3 SDRAM products.

The texture observation has long been the core technique in liquid crystal (LC)-based biosensing. One of the drawbacks of this observational means is the difficulty in quantitative analysis. In this invited paper, we report on our recent attempt to improve the LC-based biosensing technique through the analysis of bovine serum albumin (BSA), a protein standard commonly used in the assay of protein concentration. We propose to overcome the technical limitations in the analysis of LC-based biosensors by considering alternative measuring schemes. By means of the induced changes in electro-optical properties of LCs in the presence of different concentrations of BSA, novel quantitative techniques specific for LC-based biosensors are developed.

Induced Groundwater Flux by Increases in the Aquifer\'s Total Stress

Fluid-filled granular soils experience changes in total stress because of earth and oceanic tides, earthquakes, erosion, sedimentation, and changes in atmospheric pressure. The pore volume may deform in response to the changes in stress and this may lead to changes in pore fluid pressure. The transient fluid flow can therefore be induced by the gradient in excess pressure in a fluid-saturated porous medium. This work demonstrates the use of stochastic methodology in prediction of induced one-dimensional field-scale groundwater flow through a heterogeneous aquifer. A closed-form of mean groundwater flux is developed to quantify the induced field-scale mean behavior of groundwater flow and analyze the impacts of the spatial correlation length scale of log hydraulic conductivity and the pore compressibility. The findings provided here could be useful for the rational planning and management of groundwater resources in aquifers that contain lenses with large vertical aquifer matrix compressibility values.

Dynamic Pipeline-Partitioned Video Decoding on Symmetric Stream Multiprocessors

In this paper, we have implemented a dynamic pipeline-partitioning video decoder for the symmetric stream multiprocessor (SSMP) architecture. The SSMP architecture extends the traditional symmetric multiprocessor (SMP) architecture with dedicated per-core scratchpad memories and inter-processor communication (IPC) controllers for efficient data passing between the processor cores. The SSMP architecture allows the processor cores to cooperate efficiently in a fine-grained software pipeline fashion. A traditional software pipelined video decoder has fixed pipeline-stage partitions. The AVC/H.264 video decoder investigated in this paper dynamically assigns different stages of the video macroblock (MB) decoding tasks to different processor cores in order to maintain load balance among the processor cores. The pipeline partitioning policy is based on the queue levels of the inter-stage buffers. Experimental results show that, on average, the proposed dynamic pipeline-partitioning video decoder is 34% faster compared to a wavefront-based parallel video decoder.

Performance Analysis of Fano Coding

A rigorous performance analysis of Fano coding is presented, providing an upper bound on the average codeword length of binary and ternary Fano codes for an arbitrary discrete memoryless source. The performance bound is slightly better than Shannon\'s well-known bound for Shannon coding. As a by-product a novel general lower bound on Shannon entropy is derived that might be of interest also in a different context. This bound is expressed with the help of variational distance and provides a special case of a reverse Pinsker inequality.
