The concept of directionally unbiased optical multiport is introduced, in which photons may reflect back out the input direction. It acts as universal qubit and Bell-state processor to implement probabilistic quantum gates.
Quantum computers have been shown to be capable of performing certain kinds of tasks exponentially faster than classical computers. As a result, an enormous amount of effort has gone into their development. Although advances have been made, the ultimate goal of a large-scale programmable, general-purpose quantum computer still seems to be a relatively long way off. Therefore it is useful to consider...
We present the concept of logarithmic computation for neural networks. We explore how logarithmic encoding of non-uniformly distributed weights and activations is preferred over linear encoding at resolutions of 4 bits and less. Logarithmic encoding enables networks to 1) achieve higher classification accuracies than fixed-point at low resolutions and 2) eliminate bulky digital multipliers. We demonstrate...
This paper presents a silicon-proven fault tolerant FPGA architecture that can repair a wide range of hardware faults. This new architecture does not require fine-grained location of fault, and the error map is stored in non-volatile memory that is monolithically integrated on top of the CMOS circuit. Redundancy operations are fully self-contained and do not affect data streaming in and out of the...
We showed here that the scale-up of the production of the rickettsiae could benefit of the control of the migration properties of the host cells. Indeed, bead to bead transfer of endothelial cells, either normal or SV40 transformed and immortalized, was shown to be efficient in cell subculturing using Cytodex 3 microcarriers either if grown in roller-bottles or stirred tank. It should be mentioned...
This case study compares the usefulness and applicability of eight computer tools with respect to the validation of logic control programs for continuous processes. Six simulation packages (Taylor’s Mat-lab-based simulator, Simulink/StateFlow, gPROMS, Shift, Dymola, and BaSiP) and two verification tools (SMV and HyTech) were applied to a single process control example with non-trivial continuous dynamics...
In bombardments of 90Zr, 92Zr and 94Mo with 90Zr ions at energies near the Coulomb barrier, radiative fusion has been observed where the compound nuclei do not evaporate nucleons but emit only γ radiation. The deexcitation by the emission of γ radiation only is probably favoured by the very low excitation energy of the compound nuclei. In addition a substantial enhancement of the El γ strength in...
Matrix multiplication, enabled by multiply-and-accumulate hardware, is ubiquitous in signal processing, computer graphics, machine learning, and optimization. Many important applications with inherent robustness to reduced precision for matrix multiplication, e.g. inference for neural networks [1], can take advantage of analog signal processing for energy efficiency. This work presents a 64-cycle...
Photonic BiCMOS is a novel technology for fabricating electronic-photonic integrated circuits. Broadband silicon photonics devices such as germanium photodiodes and depletion type Mach-Zehnder modulators were monolithically integrated in a high performance SiGe BiCMOS baseline process. Integration aspects and first examples of demonstrator circuits shall be reviewed.
We present matrix factorization as an enabling technique for analog-to-digital matrix multiplication (AD-MM). We show that factorization in the analog domain increases the total precision of AD-MM in precision-limited analog multiplication, reduces the number of analog-to-digital (A/D) conversions needed for overcomplete matrices, and avoids unneeded computations in the digital domain. Finally, we...
Based on the characteristics of Indonesian and Japanese language, we did several experiments on the additional process to an Indonesian-Japanese statistical machine translation (SMT). We proposed several additional processes such as employing the POS tag information, adding the size of monolingual target corpus, using Indonesian stemmer in Indonesian to Japanese translation, eliminating Japanese particle...
High performance image analytics is an important challenge for big data processing as image and video data is a huge portion of big data e.g. generated by a tremendous amount of image sensors worldwide. This paper presents a case study for image analytics namely the parallel connected component labeling (CCL) which is one of the first steps of image analytics in general. It is shown that a high performance...
A technique for object identification using pairs of correlated photons is presented. The detection of rotational symmetries by measuring the joint orbital angular momentum spectrum demonstrates a sparse sensing technique relevant to remote sensing applications.
A spatial domain perceptual image codec based on subsampling and perceptual quantization (SSPQ) guided by the just-noticeable distortion (JND) profile is proposed. SSPQ integrates perceptual image coding and progressive transmission in one framework. The input image is first subsampled by a factor of two in both dimensions and the subsampled image is compressed without loss. The subsampled image provides...
The impact of Cu interconnect scaling on the write/read margin, energy dissipation, speed and reliability of resistive cross-point memory array are quantitatively examined for wire sizes down to the sub-10nm node. The impending resistivity increase due to wire scaling results in significantly degraded write and read windows, substantial interconnect energy, and increased wire latency. The growing...
In this article, a technique to relax particle image velocimetry (PIV) based on the analysis of motion blurring of particles is proposed in order to reduce the frame rate required for measurement of particle velocities. Another advantage is the relaxation of the requirements of the measurement setup while retaining the principle of measurement analysis. This technique is based on convolutions with...
SRAM based configuration memory is the primary contributor to the large area, delay, and power consumption of FPGAs relative to ASICs. In [1] it is estimated that a 3D-FPGA with the configuration memory stacked on top of the FPGA logic and routing can achieve 57% smaller die area than a baseline 2D-FPGA in 65nm CMOS technology. Motivated by these potential performance gains, several programmable logic...
A Fast and Lossless Image Compression (FLIC) algorithm based on the median edge predictor and Golomb coder of JPEG-LS is presented. FLIC eliminates the gradient-based context model from the JPEG-LS standard, the most expensive parts with respect to computational complexity and memory space requirements. To avoid a large context memory, Golomb parameter is selected based on the coding states and the...
Many state-of-the-art lossless image compression standards feature adaptive error modelling. This, however, leads to data dependency loops of the compression scheme such that a parallel compression of neighboring pixels is not possible. In this paper, we analyse the parallelism provided in JPEG-LS by the large number of different and independent context sets. An out-of-order scheduling algorithm is...
