Content-based image retrieval (CBIR) uses the content features for retrieving and searching the images in a given large database. Earlier, different hand feature descriptor designs are researched based on cues that are visual such as shape, colour, and texture used to represent these images. Although, deep learning technologies have widely been applied as an alternative to designing engineering that is dominant for over a decade. The features are automatically learnt through the data. This research work proposes integrated dual deep convolutional neural network (IDD-CNN), IDD-CNN comprises two distinctive CNN, first CNN exploits the features and further custom CNN is designed for exploiting the custom features. Moreover, a novel directed graph is designed that comprises the two blocks i.e. learning block and memory block which helps in finding the similarity among images; since this research considers the large dataset, an optimal strategy is introduced for compact features. Moreover, IDD-CNN is evaluated considering the two distinctive benchmark datasets the oxford dataset considering mean average precision (mAP) metrics and comparative analysis shows IDD-CNN outperforms the other existing model.
基于内容的图像检索(CBIR)利用内容特征对给定的大型数据库中的图像进行检索和搜索。早先,不同的手特征描述符设计是基于视觉线索,如形状、颜色和纹理,用于表示这些图像。尽管如此,深度学习技术作为设计工程的替代方案已经被广泛应用了十多年。通过数据自动学习特征。本研究提出了集成双深度卷积神经网络(IDD-CNN), IDD-CNN包括两个不同的CNN,首先CNN利用自定义特征,然后设计自定义CNN来利用自定义特征。此外,设计了一种新的有向图,该有向图由学习块和记忆块组成,有助于发现图像之间的相似性;由于本研究考虑的是大型数据集,因此引入了紧凑特征的最优策略。此外,考虑两个不同的基准数据集对IDD-CNN进行了评估,牛津数据集考虑了平均平均精度(mAP)指标,对比分析表明IDD-CNN优于其他现有模型。

In this paper, a novel reduced instruction set computer (RISC)- communication processor (RCP) has been designed with 32-bit operations which access 64-bit instruction format and implemented using field programmable gate array (FPGA). The design of the RISC processor is facilitated with communication operations like basic signals sine, cosine, and square, and modulation schemes like amplitude modulation, amplitude shift keying, analog, and digital quadrature amplitude modulation. Additionally, application-oriented operations like a traffic light, digital clock, and linear feedback shift register are included in the design. The pipeline mechanism is incorporated in the design to enhance the performance characteristics of the processor, hence allowing the execution of the instructions more effectively. Also, the design is implemented with Xilinx Virtex 7 family FPGA. The device utilization analysis of the proposed FPGA along with different FPGA families is evaluated and compared.

Agriculture is essential to the prosperity of agricultural countries like India. Thus, the suggested strategy is to use automation and internet of thing (IoT) technology to make agriculture smart. Applications enabled by the IoTs include irrigation decision assistance, crop growth monitoring and selection, and more. an Arduino-powered technology that boosts agricultural productivity. This study's main goal is to find the least quantity of water necessary to grow crops. Most farmers squander a lot of time on the fields rather than concentrating on the water that plants have access to at the right moment. The suggested system determines the required amount of water based on the data obtained from the sensors. Two sensors provide data on the soil's temperature, humidity, amount of sunlight each day, and soil temperature to the base station. The suggested systems must determine the amount of water required for irrigation based on these criteria. The system's main benefit is the use of precision agriculture (PA) in conjunction with cloud computing, which will maximise the use of water fertilisers while maximising crop yields and also assist in determining field weather conditions.
农业对印度等农业国家的繁荣至关重要。因此,建议的策略是使用自动化和物联网(IoT)技术使农业智能化。物联网的应用包括灌溉决策辅助、作物生长监测和选择等。这是一种由arduino驱动的技术,可以提高农业生产率。这项研究的主要目标是找到种植作物所需的最少水量。大多数农民在田里浪费了大量的时间,而不是把精力集中在植物在适当的时候可以获得的水上。建议的系统根据从传感器获得的数据确定所需的水量。两个传感器向基站提供土壤温度、湿度、每天的日照量和土壤温度等数据。建议的系统必须根据这些标准确定灌溉所需的水量。该系统的主要优点是将精准农业(PA)与云计算相结合,这将最大限度地利用水肥,同时最大限度地提高作物产量,还有助于确定田间天气条件。

This paper demonstrates a framework that entails a bottom-up approach to accelerate research, development, and verification of neuro-inspired sensing devices for real-life applications. Previous work in neuromorphic engineering mostly considered application-specific designs which is a strong limitation for researchers to develop novel applications and emulate the true behaviour of neuro-inspired systems. Hence to enable the fully parallel brain-like computations, this paper proposes a methodology where a spiking neuron model was emulated in software and electronic circuits were then implemented and characterized. The proposed approach offers a unique perspective whereby experimental measurements taken from a fabricated device allowing empirical models to be developed. This technique acts as a bridge between the theoretical and practical aspects of neuro-inspired devices. It is shown through software simulations and empirical modelling that the proposed technique is capable of replicating neural dynamics and post-synaptic potentials. Retrospectively, the proposed framework offers a first step towards open-source neuro-inspired hardware for a range of applications such as healthcare, applied machine learning and the internet of things (IoT).

The numerically controlled oscillator (NCO) is one of the digital oscillator signal generators. It can generate the clocked, synchronous, discrete waveform, and generally sinusoidal. Often NCOs care utilized in the combinations of digital to analog converter (DAC) at the outputs for creating direct digital synthesizer (DDS). The network on chips (NOCs) are utilized in various communication systems that are fully digital or mixed signals such as synthesis of arbitrary wave, precise control for sonar systems or phased array radar, digital down/up converters, all the digital phase locked loops (PLLs) for cellular and personal communication system (PCS) base stations and drivers for acoustic or optical transmissions and multilevel phase shift keying/frequency shift keying (PSK/FSK) modulators or demodulators (modem). The basic architecture of NCO will be enhanced and improved with less hardware for facilitating complete system level support to various sorts of modulation with minimum FPGA resources. In this paper design and memory optimization of hybrid gate diffusion input (GDI) numerically controlled oscillator based on field programmable gate array (FPGA) is implemented. compared with NCO based 8-bit microchip, memory optimization of hybrid GDI numerically controlled oscillator based on FPGA gives effective outcome in terms of delay, metal-oxide-semiconductor field-effect transistors (MOSFET’s) and nodes.
数控振荡器(NCO)是数字振荡器信号发生器的一种。它可以产生时钟,同步,离散波形,一般正弦。通常,NCOs被用于在输出端组合数模转换器(DAC)以创建直接数字合成器(DDS)。片上网络(noc)用于各种全数字或混合信号的通信系统,如任意波的合成,声纳系统或相控阵雷达的精确控制,数字下/上转换器,蜂窝和个人通信系统(PCS)基站的所有数字锁相环(pll)和声学或光学传输的驱动器以及多电平移相键控/移频键控(PSK/FSK)调制器或解调器(调制解调器)。NCO的基本架构将以更少的硬件得到增强和改进,以便用最少的FPGA资源实现对各种调制的完整系统级支持。本文实现了基于现场可编程门阵列(FPGA)的混合门扩散输入(GDI)数控振荡器的设计和内存优化。与基于NCO的8位微芯片相比,基于FPGA的混合GDI数控振荡器的内存优化在时延、金属氧化物半导体场效应晶体管(MOSFET)和节点方面都取得了较好的效果。

A pair of wideband antenna serve as an impedance transformer for the proposed antenna, which consists of a dipole with periodic capacitive loading. Periodic capacitive loading is achieved at each sector by adding interlaced coupling lines. In order to create a broad impedance bandwidth, the periodic interlaced coupling lines split each arm of the dipole into five portions. Currents are dispersed on the various sections at different frequencies. The suggested antenna is an excellent choice for radar applications since it has a high gain and a low amount of cross polarisation. With the aid of innovative design methods including codirectional inclusion of interdigital capacitance, this research study proposes an interdigital capacitance for wideband (WB) applications interdigital capacitor (IDC). The suggested IDC antenna, which works between 4.70 and 11 GHz, has dimensions of 6.36x6.35x1.6 mm3. This page explores in-depth data on gain over frequency, far field patterns, and surface current distribution on antennas. The suggested antenna's feasibility is shown by simulation data that demonstrates excellent equality on return loss.

The primary factor contributing to the high mortality rate in our country is coronary heart disease, which affects almost 50% of people from rural regions. Internet of things (IoT) contributes effectively to the development of point of care (POC) gadgets that support the medical upkeep of an expanding agricultural population. An electrocardiogram test is crucial for analysing cardiac disorders. Therefore, we must develop a POC piece of hardware to assess the health of the heart in an affordable manner and to design it for the patients without interfering with their daily regular procedure in order to monitor the patient's coronary heart disease. As a result, we must design an uninterrupted workbench, which consists of three main integrated parts. The first is a mobile Bluetooth low energy device that has 5-lead electrocardiogram (ECG) surveillance equipment and the smallest form factor. The smart phone Android application that inherits, resolves, and maps the data sent from the ECG device comes next. The patient's information and report details are then compiled on a cloud server for the doctor's future attribution needs.

Therefore, we must develop a POC piece of hardware to assess the health of the heart in an affordable manner and to design it for the patients without interfering with their daily regular procedure in order to monitor the patient's coronary heart disease. As a result, we must design an uninterrupted workbench, which consists of three main integrated parts. The first is a mobile Bluetooth low energy device that has 5-lead electrocardiogram (ECG) surveillance equipment and the smallest form factor. The smart phone Android application that inherits, resolves, and maps the data sent from the ECG device comes next. The patient's information and report details are then compiled on a cloud server for the doctor's future attribution needs.","PeriodicalId":158991,"journal":{"name":"International Journal of Reconfigurable and Embedded Systems (IJRES)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126431433","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}

Property growth, especially in high-rise buildings in developed and developing countries, has experienced a significant increase. The increasingly expensive resources and the development of information technology encourage the growth of smart buildings in almost all countries, especially in developed and developing countries, and become a trend. The Internet of things (IoT) is the main driver in the development of smart buildings. Property businesses are competing to adopt and implement smart buildings on their properties. This is further strengthened by the development of smart cities in almost all cities around the world, one of the criteria is a smart community. The purpose of implementing smart buildings is to make property management effective and efficient. Using the systematic literature review, this paper will discuss what components must be met for a property called a smart building, then what is the role of smart buildings for an area or community, and how the current smart building trend will be in the future.
房地产增长,特别是在发达国家和发展中国家的高层建筑,经历了显著的增长。日益昂贵的资源和信息技术的发展促使智能建筑在几乎所有国家,特别是发达国家和发展中国家的增长,并成为一种趋势。物联网(IoT)是智能建筑发展的主要驱动力。房地产企业正在竞相在其物业上采用和实施智能建筑。世界上几乎所有城市都在发展智慧城市,这进一步加强了这一点,其中一个标准就是智慧社区。实施智能建筑的目的是使物业管理有效和高效。通过系统的文献综述,本文将讨论智能建筑必须满足哪些组成部分,然后智能建筑对一个地区或社区的作用是什么,以及当前的智能建筑趋势将如何在未来。

Breast cancer is the most common type of cancer in women and the leading cause of death from a malignant growth in the world. Machine learning methods have been created to help with cancer detection accuracy. There are several methods for detecting cancer. Histopathological images are more accurate. In this study, we employed the Gabor filter to extract statistical features from invasive ductal carcinoma histopathology images. From the histopathological images, we chose 100, 200, 400, 1000, and 2000 at random. These statistical features were used to train several models to classify these images as malignant or benign, including the decision tree, quadratic discriminant analysis, extra randomized trees, gradient boosting, Gaussian process, Naive Bayes, nearest centroid, multilayer perceptron, and support vector machine. The models' accuracy, sensitivity, specificity, precision, and F1_score were examined. The models produced the highest results when there were 100 images and a wavenumber of 0.2. While as the number of images increased, the models' effectiveness reduced. The most obvious finding to emerge from this study is that we suggest using deep learning instead of machine learning models for large datasets.
乳腺癌是妇女中最常见的癌症类型,也是世界上恶性肿瘤导致死亡的主要原因。机器学习方法被用来帮助提高癌症检测的准确性。有几种检测癌症的方法。组织病理学图像更准确。在这项研究中,我们使用Gabor滤波器从浸润性导管癌的组织病理学图像中提取统计特征。从组织病理图像中,我们随机选择100、200、400、1000和2000个。利用这些统计特征训练多个模型,包括决策树、二次判别分析、额外随机树、梯度增强、高斯过程、朴素贝叶斯、最近质心、多层感知机和支持向量机,对这些图像进行恶性或良性分类。检验模型的准确性、敏感性、特异性、精密度和F1_score。当有100张图像,波数为0.2时,模型产生了最高的结果。而随着图像数量的增加,模型的有效性降低。从这项研究中得出的最明显的发现是,我们建议使用深度学习而不是机器学习模型来处理大型数据集。
