This paper presents a high-speed 8-bit Flash ADC. The design, which is considered as a mixed-signal type, includes two main blocks – comparator and encoder. The comparator block contains a TIQ comparator, a control circuit, and a proposed architecture of a Double-Tail (DT) comparator. The advantage of using the DT comparator is to reduce the half number of comparators which helps reduce the design area. The comparator is implemented with custom analog design meanwhile, the encoder block is designed with digital design flow. This mixed-signal circuit is designed and simulated on 180nm CMOS technology. The 8-bit Flash ADC only employs 128 comparators. The applied input clock for testing is 50 MHz with the input voltage ranging from 0.6V to 1.8V. Comparator block outputs 127 bits of thermometer code and sends them to the encoder, which exports 7 LSB bits of the binary code. The MSB bit is decided by only one DT comparator.
本文介绍了一种高速8位Flash ADC。该设计被认为是混合信号类型,包括两个主要模块-比较器和编码器。比较器模块包含TIQ比较器、控制电路和双尾(DT)比较器的拟议架构。使用DT比较器的优点是减少了一半的比较器数量,这有助于减少设计面积。比较器采用定制模拟设计实现,编码器模块采用数字化设计流程设计。在180nm CMOS工艺上设计并仿真了该混合信号电路。8位Flash ADC只使用128个比较器。用于测试的输入时钟为50 MHz,输入电压范围为0.6V至1.8V。比较器块输出127位温度计码并发送给编码器,编码器输出7 LSB位二进制码。MSB位仅由一个DT比较器决定。

Finding a suitable job and hunting for eligible candidates are important to job seeking and human resource agencies. With the vast information about job descriptions, employees and employers need assistance to automatically detect job titles based on job description texts. In this paper, we propose the multi-label classification approach for predicting relevant job titles from job description texts, and implement the Bi-GRULSTM-CNN with different pre-trained language models to apply for the job titles prediction problem. The BERT with multilingual pre-trained model obtains the highest result by Fl-scores on both development and test sets, which are 62.20% on the development set, and 47.44% on the test set.

Satellite images contain an enormous data warehouse and give us details to the general perspective of what is happening on the earth’s surface. These images are essential for agricultural development research, urban planning, surveying and, especially for evaluating the location design of broadcast stations, the input of coverage simulation and signal quality in telecommunications. The analysis of large amounts of complex satellite imagery is challenging while the evolving semantic segmentation approaches based on convolution neural network (CNN) can assist in analyzing this amount of data. In this paper, we introduce an approach for constructing digital maps with dataset provided by Google. We utilize the efficient U-Net architecture, which is an efficient combination of EfficientNet, namely EfficientNet-B0 as the encoder to extract the geographic features with U-Net as decoder to reconstruct the detailed features map. We evaluate our models using Google satellite images which demonstrate the efficiency in terms of Dice Loss and Categorical Cross-Entropy.

Efficiency Enhancement of Evolutionary Neural Architecture Search via Training-Free Initialization 基于无训练初始化的进化神经结构搜索效率提高
Pub Date : 2021-12-21 DOI: 10.1109/NICS54270.2021.9701573
Q. Phan, N. H. Luong
In this paper, we adapt a method to enhance the efficiency of multi-objective evolutionary algorithms (MOEAs) when solving neural architecture search (NAS) problems by improving the initialization stage with minimal costs. Instead of sampling a small number of architectures from the search space, we sample a large number of architectures and estimate the performance of each one without invoking the computationally expensive training process but by using a zero-cost proxy. After ranking the architectures via their zero-cost proxy values and efficiency metrics, the best architectures are then chosen as the individuals of the initial population. To demonstrate the effectiveness of our method, we conduct experiments on the widely-used NAS-Bench-101 and NAS-Bench-201 benchmarks. Experimental results exhibit that the proposed method achieves not only considerable enhancements on the quality of initial populations but also on the overall performance of MOEAs in solving NAS problems. The source code of the paper is available at https://github.com/ELO-Lab/ENAS-TFI.
在本文中,我们采用了一种方法来提高多目标进化算法(moea)在解决神经结构搜索(NAS)问题时的效率,该方法通过以最小的代价改进初始化阶段。我们不是从搜索空间中采样少量的体系结构,而是采样大量的体系结构,并通过使用零成本代理来估计每个体系结构的性能,而不调用计算代价高昂的训练过程。在通过它们的零成本代理值和效率度量对体系结构进行排序之后,然后选择最佳体系结构作为初始种群的个体。为了证明我们的方法的有效性,我们在广泛使用的NAS-Bench-101和NAS-Bench-201基准上进行了实验。实验结果表明,该方法不仅显著提高了初始种群的质量,而且提高了moea解决NAS问题的整体性能。该论文的源代码可在https://github.com/ELO-Lab/ENAS-TFI上获得。

Function exclusion in automated security patch testing using chopped symbolic execution 使用切碎符号执行的自动安全补丁测试中的函数排除

Patch testing is a core component of patch management and is used to verify that modified software modules (i.e. an update or patch) work as expected (functional testing) and do not contain any known vulnerabilities (security testing). Security patch testing requires a lot of time and a professional security knowledge from the tester. In recent years, chopped symbolic execution has been successfully applied in automatic or semiautomatic program testing, to reduce the amount of testing work. Chopped symbolic execution (Chopper) allows users to specify “uninteresting” functions to ignore during analysis, therefore allowing the testing of software modules without running all functions of the program. It is an effective solution for path explosion (one of the main problems of symbolic execution). The effectiveness of the chopped symbolic execution method in patch testing depends on how well the ignored functions are initially chosen. In this paper, we propose a novel method to automatically exclude functions for chopped symbolic execution in patch testing, using a control flow graph. Moreover, we use cyclomatic complexity to optimize the speed of the testing process. Experimental results show that our method can automatically choose the ignored functions and reduce the required testing time, in comparison to typical Chopper techniques.
补丁测试是补丁管理的核心组成部分,用于验证修改后的软件模块(即更新或补丁)是否按预期工作(功能测试),并且不包含任何已知漏洞(安全测试)。安全补丁测试需要大量的时间和测试人员的专业安全知识。近年来,截断符号执行已成功地应用于自动或半自动程序测试中,以减少测试工作量。斩切符号执行(Chopper)允许用户指定在分析过程中忽略的“不感兴趣的”函数,因此允许在不运行程序的所有功能的情况下测试软件模块。它是解决路径爆炸(符号执行的主要问题之一)的有效方法。在补丁测试中,截断符号执行方法的有效性取决于最初选择忽略函数的程度。在本文中,我们提出了一种新的方法来自动排除在补丁测试中切割符号执行的函数,使用控制流图。此外,我们使用圈复杂度来优化测试过程的速度。实验结果表明,与典型的Chopper技术相比,该方法可以自动选择忽略的函数,减少了所需的测试时间。

There are more and more practical applications of remote sensing image retrieval in a wide variety of areas, such as land-cover analysis, ecosystem monitoring, or agriculture. It is essential to have a solution for this problem with both high accuracy and efficiency, e.g. small-sized models and low computational cost. This motivates us to propose a lightweight model for remote sensing image retrieval. We first employ interclass characteristic mining to train a cumbersome and robust model, aiming to boost the quality of retrieval results. Then, from the complex model, we apply the knowledge distillation to reduce significantly the neural network’s size. Our experiments conducted on the UC Merced Land Use dataset demonstrate the advantage of our method. Our lightweight model achieves the mAP of 0.9680 with only 3.8M parameters. This model has a higher mAP and lower number of parameters than EDML method, proposed by Cao et. al.
遥感图像检索在土地覆盖分析、生态系统监测、农业等领域的实际应用越来越广泛。对于这一问题,有一个精度高、效率高的解决方案是至关重要的,例如,小尺寸的模型和低计算成本。这促使我们提出一种轻量级的遥感图像检索模型。我们首先利用类间特征挖掘来训练一个笨重的鲁棒模型,旨在提高检索结果的质量。然后,从复杂模型出发,采用知识蒸馏的方法显著减小神经网络的规模。我们在加州大学默塞德分校土地利用数据集上进行的实验证明了我们的方法的优势。我们的轻量化模型仅用3.8M的参数就实现了0.9680的mAP。与Cao等人提出的EDML方法相比,该模型具有更高的mAP和更少的参数。

This model has a higher mAP and lower number of parameters than EDML method, proposed by Cao et. al.","PeriodicalId":296963,"journal":{"name":"2021 8th NAFOSTED Conference on Information and Computer Science (NICS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114116529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Internet of Medical Things (IoMT) has been witnessing huge leaps in its development due to the advancements of neighboring technologies. Those include 5G, big data and cloud storage. While IoMT provides a rich environment for the ultra-fast share and transfer of pathological analyses and disease diagnoses, it also presents networking and security engineers with unprecedented challenges. The need to protect the transmission of the sensitive information in relation to patients’ identities and diagnoses has always been a priority. This security problem is only exaggerated by the sheer volume of medical data to be transferred through a network in real time. This paper proposes an information security scheme for IoMT that utilizes AES-256, RSA, SHA3-512 and LSB embedding in medical scans or images. The proposed scheme not only guarantees the secure transmission of medical data through a network, but it also satisfies the conditions of user authentication and confidentiality. The numerical results showcase the superiority of the proposed scheme.
由于邻近技术的进步,医疗物联网(IoMT)的发展经历了巨大的飞跃。其中包括5G、大数据和云存储。虽然IoMT为病理分析和疾病诊断的超快速共享和传输提供了丰富的环境,但它也给网络和安全工程师带来了前所未有的挑战。保护与患者身份和诊断有关的敏感信息的传输一直是一个优先事项。通过网络实时传输的大量医疗数据只会加剧这种安全问题。本文提出了一种利用AES-256、RSA、SHA3-512和LSB嵌入医学扫描或图像的IoMT信息安全方案。该方案不仅保证了医疗数据在网络上的安全传输,而且满足了用户认证和保密的条件。数值结果表明了该方案的优越性。
