The progress of network and multimedia technologies has been phenomenal during the previous two decades. Unauthorized users will be able to copy, retransmit, modify reproduction, and upload the contents more easily as a result of this innovation. Malicious attackers are quite concerned about the development and widespread use of digital video. Digital watermarking technology gives solutions to the aforementioned problems. Watermarking methods can alleviate these issues by embedding a secret watermark in the original host data, allowing the genuine user or file owner to identify any manipulation. In this study, lots of papers have been analyzed and studied carefully, in the period 2011–2022. The historical basis of the subject should not be forgotten so studying old research will give a clear idea of the topic. To aid future researchers in this subject, we give a review of fragile watermarking approaches and some related papers presented in recent years. This paper presents a comparison of many relevant works in this field based on some of the outcomes and improvements gained in these studies, which focuses on the common characteristics that increase the effect of watermarking techniques such as invisibility, tamper detection, recovery, and security

IF 0.6 Q3 MULTIDISCIPLINARY SCIENCES Pub Date : 2023-03-31 DOI: 10.14500/aro.11174
Due to advancement in internet of medical things, the conventional health-care systems are transformed into smart health-care systems. The medical emergence services can be significantly enhanced by integration of IoMT and data analytic techniques. These technologies also examine the unexplored area of medical services that are still unseen and provide opportunity for investigation. Moreover, the concept of smart cities is not achievable without providing a smart connected healthcare scheme. Hence, the main purpose of this research is to come up with a smart healthcare system based on IoMT, Cloud and Fog computing and intelligent data analytic technique. The major objective of the proposed healthcare system is to develop a diagnostic model capable for earlier treatment of heart disease. The suggested scheme consists of distinct phases such as data acquisition, feature extraction, FogBus based edge/fog computing environment, classification, and evaluation. In data acquisition, different IoMT such as wearables and sensors devices are considered to acquire the data related to heart disease and the various features related to signal and data are extracted. Further, the deep forest technique is integrated into the proposed system for classification task and effective diagnosis capabilities of heart issues. The performance of the suggested scheme is evaluated through set of well-defined parameters. Comparison with other healthcare model was conducted for the purpose of performance evaluation. It is concluded that the proposed model has a superiority over other all other models in different aspects namely, the sensitivity measure, accuracy measure, and specificity.
由于医疗物联网的发展,传统的医疗保健系统正在向智能医疗保健系统转变。通过整合IoMT和数据分析技术,可以显著增强医疗急救服务。这些技术还检查了尚未开发的医疗服务领域,这些领域仍未被发现,并为调查提供了机会。此外,如果不提供智能互联医疗方案,智慧城市的概念是无法实现的。因此,本研究的主要目的是提出一个基于物联网、云雾计算和智能数据分析技术的智能医疗系统。提出的医疗保健系统的主要目标是开发一种能够早期治疗心脏病的诊断模型。该方案包括不同的阶段,如数据采集、特征提取、基于FogBus的边缘/雾计算环境、分类和评估。在数据采集中,考虑不同的IoMT如可穿戴设备和传感器设备来获取与心脏病相关的数据,并提取与信号和数据相关的各种特征。此外,将深度森林技术整合到该系统中,提高了心脏问题的分类任务和有效诊断能力。通过一组定义良好的参数来评估所建议方案的性能。与其他医疗保健模式进行比较,以进行绩效评价。结果表明,该模型在灵敏度、准确度和特异性等方面均优于其他所有模型。

Visual interpretation of satellite images is a very significant technique to recognize and interpret structural features, which indicate lateral growth of folds, the origin of folds, and dating of folds using the exposure dating method. In this study, Landsat 8 (ESSRI) and Google Earth images are used to recognize structural features at Pira Magroon, Surdash, and Azmar anticlines in the Sulaimaniyah vicinity, Kurdistan Region, north of Iraq. The mentioned anticlines are outstanding geomorphological and structural features in the Sulaimaniyah vicinity. The recognized and interpreted structural features include: en-echelon folding, domes, and Neotectonic indication. All these features are discussed in detail with many images to show the discussed cases, most of the interpreted data and presented figures are never mentioned previously.
卫星图像的视觉解译是识别和解释构造特征的重要技术,它可以指示褶皱的横向生长、褶皱的起源以及利用曝光测年法确定褶皱的年代。在这项研究中,使用了Landsat 8 (ESSRI)和Google Earth图像来识别伊拉克北部库尔德斯坦地区苏莱曼尼亚附近的Pira Magroon、Surdash和Azmar背斜的结构特征。上述背斜是苏莱曼尼亚附近突出的地貌和构造特征。已认识和解释的构造特征包括:列梯队褶皱、圆顶和新构造指示。详细讨论了所有这些特征,并提供了许多图像来显示所讨论的案例,大多数解释数据和呈现的图形以前从未提到过。

Fresh and Mechanical Properties of Concrete Containing Oil-Well Cutting Material 含油井切削材料混凝土的新鲜力学性能
IF 0.6 Q3 MULTIDISCIPLINARY SCIENCES Pub Date : 2023-02-25 DOI: 10.14500/aro.10962

Oil-well cutting material (OWCM) is a waste generated during the process of oil-well drilling. Its disposal is costly and harmful to the environment. The chemical makeup for the material implies that it might be used as a partial cement replacement in concrete. It is high in calcium oxide, silica, and aluminum oxide, which are the main oxides found in raw materials used to produce cement. Replacing a part of cement by OWCM in concrete mixtures can directly reduce the quantity of the cement used which leads to decreasing the emission of carbon dioxide and solving the disposal problems for the OWCM as well. This process can be considered as a significant step in producing environmentally friendly concrete. This study focuses on investigating the fresh and mechanical properties of different concrete mixes that have different strength grades, containing different percentages of OWCM as a cement replacement. For this purpose, different concrete mixes containing 10%, 15%, 20%, 25%,30%, 35%, and 40% of OWCM as a cement replacement, besides the control Portland cement for the three different concrete strength grades, were prepared. After performing the slump and flow tests, cube specimens were cast and moist-cured for 3, 28, and 90 days and subjected to compression test, whereas 28-day moist-cured cylinder specimens were subjected to splitting tensile test. The test results have revealed that in spite of small reduction in strength with replacing cement by up to 20% of OWCM, the strength of the concrete remains within the designed strength grade ranges.
油井切削材料是钻井过程中产生的废弃物。它的处理是昂贵的,对环境有害。该材料的化学成分表明,它可能用作混凝土中部分水泥的替代品。它富含氧化钙、二氧化硅和氧化铝,这是用于生产水泥的原材料中发现的主要氧化物。用OWCM代替混凝土混合料中的部分水泥,可以直接减少水泥的使用量,从而减少二氧化碳的排放,同时也解决了OWCM的处置问题。这个过程可以被认为是生产环保混凝土的重要一步。本研究的重点是研究不同强度等级的混凝土混合料的新鲜性能和力学性能,这些混凝土混合料含有不同比例的OWCM作为水泥替代品。为此,配制了含有10%、15%、20%、25%、30%、35%和40%的OWCM作为水泥替代品的不同混凝土配合比,以及用于三种不同混凝土强度等级的对照波特兰水泥。在进行坍落度和流动试验后,对立方体试件进行浇铸、湿固化3天、28天和90天进行压缩试验,对28天湿固化的圆柱体试件进行劈裂拉伸试验。试验结果表明,尽管更换水泥的强度降低了20%,但混凝土的强度仍保持在设计的强度等级范围内。

Effect of Hot Glue Additive on the Rheological Properties of Asphalt Cement and Mixtures Performance 热胶添加剂对沥青水泥流变特性及混合料性能的影响

In general, the physical and rheological properties of asphalt binder are directly affecting the resistance of asphalt mix to the permanent deformation (rutting), water damage, and thermal cracking. The degradation in these properties leads to severe distresses that appear in the pavement and, consequently, make the repair and maintenance very expensive. Since the modified-asphalt cement may help to minimize such aforementioned distresses, this research is established for this purpose. It aims to investigate the physical and rheological properties of modified-asphalt cement with silicone, dense silicone rubber, and ethylene propylene diene monomer rubber. Five contents for each type of hot glue are investigated; 0.4, 0.8, 1.2, 1.6, and 2% of the asphalt cement weight. Conventional asphalt cement tests such as penetration, softening point, dynamic viscosity, and ductility tests are conducted to evaluate the hot glue-modified asphalt cement properties. Moreover, the Marshall and indirect tensile strength tests are conducted to examine the effect of hot glue on the performance of the asphalt mixtures at concentrations of 0.8 and 1.6% of the asphalt cement weight. The results show that the hot glue-modified asphalt cement leads to an increase in the hardness and consistency, and a reduction in the temperature susceptibility of asphalt cement. These features lead to better Marshall stability and tensile strength ratio, as compared with the standard asphalt cement mixture.
一般来说,沥青粘结剂的物理和流变性能直接影响沥青混合料对永久变形(车辙)、水损伤和热裂的抵抗力。这些性能的退化导致路面出现严重的破损,因此,使维修和维护非常昂贵。由于改性沥青水泥可能有助于减少上述痛苦,本研究是为此目的而建立的。研究了有机硅、致密硅橡胶和乙丙二烯单体橡胶改性沥青水泥的物理和流变性能。考察了每种热熔胶的5项内容;沥青水泥重量的0.4、0.8、1.2、1.6、2%。通过常规的沥青水泥渗透试验、软化点试验、动粘度试验和延性试验来评价热胶改性沥青水泥的性能。此外,通过马歇尔试验和间接抗拉强度试验,考察了热胶在沥青水泥重量的0.8和1.6%浓度下对沥青混合料性能的影响。结果表明:热胶改性沥青水泥的硬度和稠度提高,温度敏感性降低;与标准沥青水泥混合料相比,这些特性使其具有更好的马歇尔稳定性和抗拉强度比。

Nowadays, clean and high-power generation is essential matters worldwide. To be improved and optimized, power plants require accurate models that can be introduced to process simulators. There is various commercial software for industrial simulation which is not accessible to everyone. The open-source DWSIM process simulator is the first chemical engineering code that offers many tools for the better study of industrial plants. In this paper, we employ DWSIM software to simulate a combined cycle gas turbine (CCGT) power plant under design conditions for three cases. The generic models are predicted for multistage compressors and compressor maps. In the first case, two models developed in ASPEN HYSYS and GateCycle will be considered. The achieved results by DWSIM are acceptably comparable for thermal efficiency and power generation. The DWSIM result is 3.5% lower than the ASPEN HYSYS for thermal efficiency, and the power generation is completely the same. In the second case, rigorous simulation was carried out using actual field data from the local CCGT power plant. The DWSIM outcomes are very close to the practical data. The power generation of GT and CC is very close; the variety is nearly 0.45%. In the third case, the simulation of CCGT with a cogeneration system is precisely accomplished, and the outcomes of DWSIM are shown in excellent agreement. The DWSIM prediction shows lower values by 0.26%, 4.79%, and 0.72% for the HP turbine, LP turbine, and plant net power, respectively.

Tribolium confusum is one of the most common pests of many commodities, especially cereals and their products. These pests are known for being the most destructive insect pests attacking and infesting stored flour and grain in soil, warehouses, grocery stores, and homes. Therefore, this study aims to control these pests with an environmentally friendly, healthier, and cost-effective pesticide instead of the common artificial chemicals to practice the current management of cereal storage pest control in the Kurdistan Region of Iraq. For this to be achieved, the toxicity effect of crude plant extracts from five different parts of Melia azedarach in tap water with concentrations of 50%, 60%, 70%, 80%, and 90% at different times (2, 4, 6, 8, and 10 h) against stored-product insect was tested. The toxicity effect of these extracts varied based on the crude plant part extracts, concentrations, and exposure period according to the SAS system investigation on the mortality rate of T. confusum adults (Duncan test). The extracts’ compatibility with treated adults of T. confusum in the clear petri dish was noted. Besides, the number of dead adults was measured by loss of motion.
黄曲霉是许多商品,特别是谷物及其产品中最常见的害虫之一。众所周知,这些害虫是最具破坏性的害虫,它们会袭击和侵扰土壤、仓库、杂货店和家庭中储存的面粉和谷物。因此,本研究旨在用一种环保、健康、经济的农药代替常见的人工化学品来控制这些害虫,以实践伊拉克库尔德斯坦地区谷物储存库害虫控制的现有管理。为此,研究了苦楝5种不同部位的粗提取物在不同时间(2、4、6、8和10 h)浓度为50%、60%、70%、80%和90%的自来水中对储物昆虫的毒性作用。根据邓肯试验(Duncan test)的SAS系统调查,这些提取物的毒性作用因植物粗部位提取物、浓度和暴露时间的不同而不同。在透明培养皿中观察了提取物与处理过的黄芪成虫的配伍性。此外,成人死亡的数量是通过失去运动能力来衡量的。

Agriculture crops are highly significant for the sustenance of human life and act as an essential source for national income development worldwide. Plant diseases and pests are considered one of the most imperative factors influencing food production, quality, and minimize losses in production. Farmers are currently facing difficulty in identifying various plant diseases and pests, which are important to prevent plant diseases effectively in a complicated environment. The recent development of deep learning techniques has found use in the diagnosis of plant diseases and pests, providing a robust tool with highly accurate results. In this context, this paper presents a comprehensive review of the literature that aims to identify the state of the art of the use of convolutional neural networks (CNNs) in the process of diagnosing and identification of plant pest and diseases. In addition, it presents some issues that are facing the models performance, and also indicates gaps that should be addressed in the future. In this regard, we review studies with various methods that addressed plant disease detection, dataset characteristics, the crops, and pathogens. Moreover, it discusses the commonly employed five-step methodology for plant disease recognition, involving data acquisition, preprocessing, segmentation, feature extraction, and classification. It discusses various deep learning architecture-based solutions that have a faster convergence rate of plant disease recognition. From this review, it is possible to understand the innovative trends regarding the use of CNN’s algorithms in the plant diseases diagnosis and to recognize the gaps that need the attention of the research community.

Technology has dominated a huge part of human life. Furthermore, technology users use language continuously to express feelings and sentiments about things. The science behind identifying human attitudes toward a particular product, service,or topic is one of the most active fields of research, and it is called sentiment analysis. While the English language is making real progress in sentiment analysis daily, other less-resourced languages, such as Kurdish, still suffer from fundamental issues and challenges in Natural Language Processing (NLP). This paper experimentswith the recently published medical corpus using the classical machine learning method and the latest deep learning tool in NLP and Bidirectional Encoder Representations from Transformers (BERT). We evaluated the findings of both machine learning and deep learning. The outcome indicates that BERT outperforms all the machine learning classifiers by scoring (92%) in accuracy, which is by two points higher than machine learning classifiers.
科技已经主导了人类生活的很大一部分。此外,技术用户不断使用语言来表达对事物的感受和情绪。识别人们对特定产品、服务或主题的态度背后的科学是最活跃的研究领域之一,它被称为情感分析。虽然英语在情感分析方面每天都在取得真正的进步,但其他资源较少的语言,如库尔德语,在自然语言处理(NLP)方面仍然受到基本问题和挑战的困扰。本文使用经典的机器学习方法和最新的深度学习工具NLP和双向编码器表示(BERT)对最近发表的医学语料库进行了实验。我们评估了机器学习和深度学习的发现。结果表明,BERT的准确率(92%)高于所有机器学习分类器,比机器学习分类器高出2分。

This process of this paper is carried out using thechemical spraying method to produce homogeneous thin films ofpure cadmium sulfide-doped with silver at different percentagesof 1%, 3%, and 5% on glass and polyimide plastic substrates at300°C. The aim is to study the optical and structural properties of the samples and the effect of the silver doping rate on films producedwith these properties. Due to X-ray diffraction studies, all filmscreated had a hexagonal phase, and it was noticed that they had avery precise structure free of holes or cracks. The obtained crystalsize ranged between 22.74 nm and 55.05 nm for different substrates, and the prominent plane was (002). From the optical properties, all films exhibited transmission higher than 60%, thus showing a lowabsorption, which makes them be used as light-permeable layers in the Solar Cell system. In addition, emission peaks were revealed by photo luminescence spectra examination at wavelengths ranging between (542.94 nm) and (546.02 nm), which led to calculate the energy gap (Eg). of the produced films, ranged between (2.27 eV) and (2.28 eV) for the different substrates.
