The first CNN technology-based, high performance industrial visual computer called Aladdin is reported. The revolutionary device is the world premier of the ACE4k Cellular Visual Microprocessor (CVM) chip powering an industrial visual computer. One of the most important features of the Aladdin system is the image processing library. The library reduces algorithm development time, provides efficient codes, error free operation in binary, and accurate operation in grayscale nodes. Moreover the library provides an easy way to use the Aladdin system for those who are not familiar with the CNN technology.

Nitrated-pyrazole-based energetic compounds have attracted wide publicity in the field of energetic materials (EMs) due to their high heat of formation, high density, tailored thermal stability, and detonation performance. Many nitrated-pyrazole-based energetic compounds have been developed to meet the increasing demands of high power, low sensitivity, and eco-friendly environment, and they have good applications in explosives, propellants, and pyrotechnics. Continuous and growing efforts have been committed to promote the rapid development of nitrated-pyrazole-based EMs in the last decade, especially through large amounts of Chinese research. Some of the ultimate aims of nitrated-pyrazole-based materials are to develop potential candidates of castable explosives, explore novel insensitive high energy materials, search for low cost synthesis strategies, high efficiency, and green environmental protection, and further widen the applications of EMs. This review article aims to present the recent processes in the synthesis and physical and explosive performances of the nitrated-pyrazole-based Ems, including monopyrazoles with nitro, bispyrazoles with nitro, nitropyrazolo[4,3-c]pyrazoles, and their derivatives, and to comb the development trend of these compounds. This review intends to prompt fresh concepts for designing prominent high-performance nitropyrazole-based EMs.

Navigation signals should be steadily tracked to allow the extraction of navigation information, and support the calculation of navigation solution. Generally, extraction of navigation information is realized by GNSS tracking loops, which need to implement two critical operations: 1) tracking parameters should be precisely estimated in order to reliably decode the navigation message. 2) Successive tracking method of navigation information. This paper proposes a novel tracking framework using dynamic FLL assisting PLL strategy and a loop state detection monitor. The new framework extends traditional phase and delay locked loop (PLL/DLL) tracking framework, and contributions mainly lie in two parts. A dynamic framework for parameters adjustment is proposed to avoid tracking failure due to the change of environment, which is complemented in a FLL-PLL cooperative framework. Experimental results demonstrate the advantages of our algorithm compared with standard PLL/DLL framework. It is shown that the algorithm proposed is more suitable for tracking under signal attenuation situation, while maintaining high performance at the same time.

A statistical approach for modeling the code vectors designed using a supervised learning neural network is proposed in this paper. Since wavelet-based compression is more robust under transmission and decoding errors, the proposed work is implemented in the wavelet domain. Two crucial issues in compression methods are the coding efficiency and the psycho visual quality achieved while modeling different image regions. In this paper, a high performance wavelet coder which provides a new framework for handling these issues in a simple and effective manner is proposed. First the input image is subjected to wavelet transform. Then the transformed coefficients are subjected to Quantization followed by the well known Huffman Encoder. In the Quantization process, initially a codebook is designed using Learning Vector Quantizer. Since codebook is an essential component for the reconstructed image quality and also to exploit the spatial energy compaction of the codevectors, the codebook is further modeled using Savitzky–Golay polynomial. Experimental results show that the proposed work gives better results in terms of PSNR that are competitive with the state-of-art coders in literature.

The new JAliEn (Java ALICE Environment) middleware is a Grid framework designed to satisfy the needs of the ALICE experiment for the LHC Run 3, such as providing a high-performance and high-scalability service to cope with the increased volumes of collected data. This new framework also introduces a split, two-layered job pilot, creating a new approach to how jobs are handled and executed within the Grid. Each layer runs on a separate JVM, with a separate authentication token, allowing for a finer control of permissions and improved isolation of the payload. Having these separate layers also allows for the execution of job payloads within containers. This allows for the further strengthening of isolation and creates a cohesive environment across computing sites, while avoiding the resource overhead associated with traditional virtualisation. This contribution presents the architecture of the new split job pilot found in JAliEn, and the methods used to achieve the execution of Grid jobs while maintaining reliable communication between layers. Specifically, how this is achieved despite the possibility of a layer being run in a separate container, while retaining isolation and mitigating possible security risks. Furthermore, we discuss how the implementation remains agnostic to the choice of container platform, allowing it to run within popular platforms such as Singularity and Docker.
