The main factors effecting the usage of recycled course aggregate (RCA) in concrete mix was its lack of quality. The surface of the recycled aggregate may contain some cement mortar which affects the quality of recycled aggregate. This paper is about to study on recycled aggregate in various test performances by the acid soaking treatment methods using sulphuric acid, nitric acid, hydrochloric acid. FIVE series of concrete mixtures are prepared those are natural aggregate, recycled aggregate, recycled aggregate with HCL, recycled aggregate with H2SO4, recycled aggregate with HNO3. The effectiveness of using these treated recycled aggregate in concrete and strength, durability characteristics of concrete were examined and their properties of aggregates were calculated. In the test results the behaviour of recycled aggregate has improved after soaking in acid treatment. Out of this three acids first recycled aggregates treated with sulphuric acid has given best results, after that nitric acid somehow better but hydrochloric acid has given very poor performance. From the overall study the strength and durability characteristics of concrete by recycled aggregate can be improved in a good way by using the treated recycled aggregate in concrete.
影响再生层骨料在混凝土配合比中使用的主要因素是再生层骨料质量差。再生骨料表面可能含有一定量的水泥砂浆,影响再生骨料的质量。本文拟对再生骨料采用硫酸、硝酸、盐酸等酸浸处理方法进行各种试验性能的研究。配制了天然骨料、再生骨料、HCL再生骨料、H2SO4再生骨料、HNO3再生骨料五大系列混凝土配合比。考察了处理后的再生骨料在混凝土中的使用效果和混凝土的强度、耐久性特性,并计算了其骨料性能。试验结果表明,经酸浸处理后,再生骨料的性能有所改善。在这三种酸中,首先用硫酸处理再生骨料的效果最好,然后用硝酸处理效果更好,但盐酸的效果很差。从整体研究来看,在混凝土中使用处理后的再生骨料可以很好地提高再生骨料混凝土的强度和耐久性。

Self-compacting concrete has emerged as a creative invention that is capable of solving the problem and making a remarkable advancement in the field of substantial innovation, which has led to the prior practise of substantial design free from vibration. Self-compacting concrete use today is focused on higher performance, better and more solid quality, and uniformity. Self-compacting concrete (SCC) with GGBS and blended steel strands is being created in this research. The goal of this work is to create M30 SCC with GGBS cream steel fibers and compare its strength to normal concrete. The IS 10262 2009 standard is used to produce regular cement, whereas the alter Nan Su approach is used to produce SCC. In order to increase the volume of cement, the significant is replaced by 0, 10, 20, 30, and 40% of GGBS with the addition of stable steel strands at a 0.5% expansion. The compressive strength of SCC is determined using 3D squares of size 150x150x150mm, while the split tensile strength is determined using cylinder-shaped examples of size 150x300mm, and the flexural strength of SCC is determined using crystals of size 100x100x500mm.
自密实混凝土作为一项创造性的发明而出现,它能够解决这一问题,并在实质性创新领域取得了显著的进步,这导致了先前的无振动实质性设计实践。当今自密实混凝土的使用重点是更高的性能,更好和更坚实的质量,和均匀性。本研究研制了含GGBS和钢绞线的自密实混凝土(SCC)。这项工作的目标是用GGBS奶油钢纤维制造M30 SCC,并将其强度与普通混凝土进行比较。IS 10262 2009标准用于生产普通水泥,而另一种南苏方法用于生产SCC。为了增加水泥的体积,可以用0、10、20、30和40%的GGBS代替,并加入膨胀率为0.5%的稳定钢绞线。SCC的抗压强度采用尺寸为150x150x150mm的三维正方形来确定,劈裂抗拉强度采用尺寸为150x300mm的圆柱形样例来确定,抗折强度采用尺寸为100x100x500mm的晶体来确定。

Design Verification in VLSI is the most important step in the product development process. It aims to confirm that the system designed meets with the standards and requirements of the system. Verification is the process of checking whether the designed system performs all the required functionality specified in the design by writing the test bench or verification environment that contains group of classes and modules which generates input stimulus to the system and the output from that design is compared with the expected output. A communication system has set of roles those are called protocols. UART is a serial communication protocol that is used when only two devices are needed to communicate and it uses peer to peer topology. I2C stands for Inter Integrated Circuit used for communication between master and slave in which more than one slave devices or memory can be connected to a master device. System Verilog has been primarily used for the verification purposes in VLSI because it has the features of Hardware Description Languages such as Verilog and VHDL, C and C++ and functional coverage, assertion coverage, constrained randomization and supports OOPs concepts.
超大规模集成电路中的设计验证是产品开发过程中最重要的一步。其目的是确认所设计的系统是否符合系统的标准和要求。验证是通过编写包含一组类和模块的测试台架或验证环境来检查所设计的系统是否执行设计中指定的所有所需功能的过程,这些类和模块为系统产生输入刺激,并将该设计的输出与预期输出进行比较。通信系统有一组角色,这些角色被称为协议。UART是一种串行通信协议,当只需要两个设备进行通信时使用,它使用点对点拓扑。I2C代表内部集成电路,用于主设备和从设备之间的通信,其中多个从设备或存储器可以连接到主设备。系统Verilog主要用于VLSI中的验证目的,因为它具有硬件描述语言(如Verilog和VHDL, C和c++)以及功能覆盖,断言覆盖,约束随机化和支持oop概念的功能。

Individuals today suffer from a wide range of diseases as a result of their lifestyle choices and the environment in which they live. The objective of forecasting disease at an earlier stage becomes an increasingly vital condition as the identification and prediction of such diseases at their earlier phases become highly significant. Most individuals are too lazy to go to the hospital or see a doctor for a small problem. Our approach focuses on accuracy to detect additional symptoms for illness prediction in healthcare. In this section, I've employed a variety of machine learning algorithms carefully and focused in this few, which achieved the highest accuracy with that specific condition in order to build a strong model that produces the most exact forecasts. This work introduces the topics of illness prediction, disease therapy, and local medical consultation with effective machine learning programming. There are several diseases in the world that are brought on by the conditions of people's living habits or their surroundings. Thus, this study offers a summary of machine learning-based illness prediction.
由于人们所选择的生活方式和所处的环境,今天的人们患有各种各样的疾病。由于在疾病的早期阶段识别和预测这些疾病变得非常重要,因此在早期阶段预测疾病的目标变得越来越重要。大多数人懒得为一个小问题去医院或看医生。我们的方法侧重于准确性,以检测额外的症状,疾病预测在医疗保健。在本节中,我仔细地使用了各种机器学习算法,并专注于这几种算法,这些算法在特定条件下达到了最高的精度,以便建立一个强大的模型,产生最准确的预测。这项工作引入了疾病预测,疾病治疗和有效的机器学习编程的本地医疗咨询的主题。世界上有几种疾病是由人们的生活习惯或周围环境引起的。因此,本研究为基于机器学习的疾病预测提供了一个总结。

Multiple Attribute Decision Making (MADM) is a popular method to be selected in numerous studies in solving decision-making cases. Methods like SAW, WASPAS, SMART, and WP are preferred among researchers to be used for many purposes. However, the best method still not compared in determining best employee. Hence, the study conducted the comparison between the methods by using the Rank Similarity Index (RSI). The index is used to express the most appropriate method. In terms of weighting, we propose the D-CRITIC method as the tool to support the comparison procedure. Moreover, we select the bus driver as the sample case of the study with total of 10 candidates are nominated to be chosen as the best. The company has given the rank list before, so we just compare the actual rank with the result of MADM methods calculations. The result shows that SAW and WASPAS are the methods with the highest similarity towards the rank. Furthermore, these methods also reach the great score of the RSI between the others.
多属性决策(MADM)是众多研究中常用的解决决策问题的方法。SAW、WASPAS、SMART和WP等方法被研究人员用于多种目的。然而,在确定最佳员工时,仍然没有比较最佳的方法。因此,本研究采用秩相似指数(Rank Similarity Index, RSI)对两种方法进行比较。索引是用来表示最合适的方法。在权重方面,我们提出D-CRITIC方法作为支持比较过程的工具。此外,我们选择公交车司机作为研究的样本案例,总共有10名候选人被提名为最佳人选。公司之前已经给出了排名表,所以我们只是将实际排名与MADM方法计算的结果进行比较。结果表明,SAW和WASPAS是排序相似度最高的方法。此外,这些方法在RSI方面也达到了较高的分数。

Water that is clean and hygienic must be available for drinking. Most of the water that is currently available needs to be cleaned. When water is contaminated, it may be required to recycle it. Water must be treated to eliminate impurities and standardize variables like turbidity and pH. Many of the treatment facilities employ any organic coagulants for the treatment, like alum, ferrous sulphate, etc.The usage of plant-based coagulants was developed since these coagulants are hazardous to living things.The utilization of biological plant materials as coagulants, such as agricultural waste, Chitosan, Moringa oliefera, maize seed, cactus plant, etc., has been thoroughly researched. In this project, studies are carried out to determine the turbidity removal efficiency utilizing locally accessible moringa oliefera. The outcomes are encouraging because the optimal dosage is 200 mg/l with an 88.9% clearance efficiency in dry form.
必须提供干净卫生的饮用水。目前大部分可用的水都需要净化。当水被污染时,可能需要回收它。必须对水进行处理,以消除杂质,并使浊度和ph等变量标准化。许多处理设施使用任何有机混凝剂进行处理,如明矾、硫酸亚铁等。由于这些混凝剂对生物有害,因此开发了植物基混凝剂的使用。利用农业废弃物、壳聚糖、辣木、玉米种子、仙人掌等植物生物材料作为混凝剂的研究较为深入。在这个项目中,研究了利用当地可获得的辣木来确定除浊效率。结果令人鼓舞,因为最佳剂量为200mg /l,干燥形式的清除率为88.9%。

Overhead tank are generally classified as Ordinary Moment Resisting Frame (OMRF) and Special Moment Resisting Frame (SMRF) supported response reduction factor. Generally, the Overhead tank consists of structural members like slabs, beams, columns, and footings, where the subjected loads are transferred between the structural members and eventually transferred to the Sub-grade of the soil. The behavior of the Overhead tank is different for various sorts of loadings (Dead, Live, Wind, and Seismic) within the analysis and of overhead tank usefully Indian standards codes suggest various loads combinations supported probability of Occurrence. There are around 52 load combinations and IS codes suggest the lateral load (wind and seismic) acts independently but the load governing the planning of structural members is to be acknowledged. and therefore the present study to research the consequences of wind and seismic forces on Overhead tank structures of heights (15m) are considered in seismic zones II, III, IV, V where length and width of the structures are kept constant. An earthquake load is calculated as per IS and wind pressure calculated as per IS 875-1987. The analysis is done the use of STAAD.pro software.
架空油箱一般分为普通抗弯矩框架(OMRF)和特殊抗弯矩框架(SMRF)两种。一般来说,架空储罐由板、梁、柱、底座等构件组成,承受的荷载在构件之间传递,最终传递到土的路基上。在分析中,架空储罐的行为对于各种负载(死荷载、活荷载、风荷载和地震荷载)是不同的,而架空储罐的印度标准规范提出了各种支持发生概率的负载组合。大约有52种荷载组合,IS规范表明侧向荷载(风荷载和地震荷载)是独立作用的,但控制结构构件规划的荷载是要承认的。因此,本研究将在II、III、IV、V地震带考虑风和地震力对高度(15米)的架空罐结构的影响,其中结构的长度和宽度保持不变。地震荷载按is计算,风压按is 875-1987计算。分析是使用STAAD完成的。专业软件。

In this paper All countries are focusing on sustainable technology that can be economical and adopted for the use of concrete in a better way. Concrete is most widely used construction material and it possess very low tensile strength, shear strength and brittle characteristics. In order to improve this property a new construction materials were developed through research and development work called asbestos fiber concrete and recron 3s fibers concrete. M30 gradeof concrete was designed. The addition of asbestos fiber and recron 3S fiberthe concrete. To determine the properties like tensile strength, compressive strength and flexural strength were performed at different ages like 7,14 and 28 days. The addition of asbestos fiber varies from 0%, 0.25%, 0.5%, 0.75%and 1% by volume of concrete and recron 3S fiber varies from 0%, 0.25%, 0.5%, 0.75% and 1% by volume of concrete.
