Active page replacement approaches are required for the virtual memory for the purpose of resolving what data pages are going to be driven out from the memory when a page fault occurs. For years, a lot of algorithms have been developed to avoid page fault, all these algorithms have the efforts of decreasing the proportion related to the reduce error in the same time as incurring minimal overhead. Since up-to-date patterns of memory access have been studied, the study has the aim of creating novel methods for page replacement that can be adaptive to the varying workloads. The presented review aims of comparing the assessed replacement time for the main methods of page replacement. Some conventional methods like CLOCK and LRU will be examined, as well as some new methods like 2-DPR, CLOCK-Pro, LIRS, and CAR.

The development of the automotive industry in the world continues to grow, including also the development of the automotive industry in Indonesia, along with the development of the business, supporting industries that supply components for parts used for automotive must prepare it, especially in terms of quality, quantity, and accuracy of delivery. There are still several automotive failures in terms of quality that have caused recall, it’s as the reason why the research was conducted. Research carried out in one of the oil filter manufacturing industries where defect products namely peel off on the seaming area was reached 35.21%from the total amount of defects that occurred. The focus and purpose of the research are the effort to reduce printing defects. Several techniques are used in this research, such as work time measurement, line balancing approach, and some statistical tools for quality improvement, such as Pareto, fishbone diagrams, and why-why analysis. The result of the study was identified that the dominant cause of printing peel off on the seaming area was caused by the handling process on the packaging line when overlapping time. The handling process has been improved by reducing process handling with added transfer conveyors. Theeffectiveness of improvement has reported in March 2019 that the number of defect printing peels off the seaming area on oil filter products decreased by 46.74%

Health monitoring is an essential task in managing both the daily routine progress of a patient/outpatient during and after the medication period. It plays not only a significant role in the overall well-being of the patient/outpatient but also as the measure of quality and effective healthcare services deliverance. However, achieving this is very challenging in areas with limited infrastructure to support a myriad of current social services, including advanced healthcare services. For instance, instead of relying only on the outpatient’s physical visitations to the healthcare center as a feedback mechanism in case of any complications during medications, continuously remote monitoring of the outpatients' health can improve the deliverance of healthcare services. This paper presents a simplified system model for remote monitoring of the outpatients well-being that has been designed to work in the limited Internet of Things (IoT) infrastructure to address the challenge above. The design is cheap and easily deployable for health remote monitoring purposes as the outpatient’s well-being can be monitored in real-time so that to facilitate detection of the subtle changes and avoid drug intoxication. The system advises and alerts in real-time the doctors/medical assistants about the changing of vital parameters in order to take preventive measures.
在服药期间和服药后,健康监测是管理病人/门诊病人日常进展的一项基本任务。它不仅在病人/门诊病人的整体健康方面发挥着重要作用,而且还作为质量和有效医疗保健服务交付的衡量标准。然而,在基础设施有限的地区,实现这一目标非常具有挑战性,这些地区无法支持大量当前的社会服务,包括先进的医疗保健服务。例如,在用药过程中出现并发症时,不再仅仅依靠门诊患者到医疗中心的实际就诊情况作为反馈机制,而是对门诊患者的健康状况进行持续的远程监控,从而提高医疗服务的提供。本文提出了一个简化的系统模型,用于远程监控门诊患者的健康状况,该模型旨在在有限的物联网(IoT)基础设施中工作,以应对上述挑战。该设计价格便宜,易于部署,可用于健康远程监控目的,因为可以实时监控门诊患者的健康状况,从而便于检测细微变化,避免药物中毒。该系统实时向医生/医疗助理提供重要参数变化的建议和警报,以便采取预防措施。

Encryption technology is one of the main means of protecting information security and includes many forms in terms of digital signatures, authentication, system security, confidentiality and data integrity and other functions. Therefore, Encryption and decryption are the best solution to protect data, especially not only sensitive data and protect them from attackers who aim to steal information. In this paper we use asymmetric encryption algorithms such as (RSA, Elliptic Curve, NTRU) that are used to send data over the network to provide security to users. We work on a review of the algorithms mentioned because of their importance in the encryption side and will give a summary of the performance of its work.

This paper deals with the experimental works on the strength of concrete cube specimens with cement replacement by various percentages (0%, 5%, 7.5%, and 10%) of silica fume in concrete mixtures. The use of supplementary cementitious material is gaining much attention owing to its high pozzolanic property and a further improvement in strength properties. Silica-fume is one among the widely used pozzolanic material which exhibits high cementing efficiency due to high silica content. The physical properties of cement with and without silica fume replacement are tested according to ASTM. Mix design calculations for concrete mixtures with 0%, 5%, 7.5% and 10% silica fume content with constant watercement ratio 0.4 are calculated for concrete mixtures according to ACI. The target strength is 34.5 MPa. Three concrete cube specimens for each mix are prepared. After 7 days and 28 days, compressive strengths of the mortar and concrete cubes are tested. According to the test results, the concrete mix with 10% silica fume has the highest compressive strength. Overall, the strength of concrete with various replacement of silica fume enhances greater strength than the normal mix with 0% replacement.
本文研究了水泥掺入不同比例(0%、5%、7.5%、10%)硅灰对混凝土立方体试件强度的影响。补充胶凝材料因其具有较高的火山灰性能和强度性能的进一步提高而受到人们的重视。硅灰是一种应用广泛的灰火山灰材料,由于硅含量高而具有较高的胶凝效率。采用和不采用硅灰替代的水泥的物理性能根据ASTM进行测试。根据ACI计算了硅灰含量为0%、5%、7.5%和10%、水灰比为0.4的混凝土配合比的配合比设计计算。目标强度为34.5 MPa。每次配合比配制3个混凝土立方体试件。分别在第7天和第28天测试砂浆和混凝土立方体的抗压强度。试验结果表明,掺量为10%硅粉的混凝土抗压强度最高。总体而言,各种硅粉替代的混凝土强度比0%替代的普通混合混凝土强度提高更大。

Overall, the strength of concrete with various replacement of silica fume enhances greater strength than the normal mix with 0% replacement.","PeriodicalId":424923,"journal":{"name":"International Journal of Engineering Research and Advanced Technology","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126258436","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}

It is very difficult for the voice impaired people to convey their messages to regular people since regular people are not trained on hand sign language, communication becomes very difficult. Therefore, I propose a speaking system that will enable dumb and deaf people to deliver their messages to normal people using hand gestures. This proposed system, use of hand gestures reading system equipped with gestures and flex sensors connected to each finger and connected to the RF Transmitter as an input along with the speaker unit. This system powered by a battery-powered circuitry to run it. Also, this system will contain different words and sentences that will help dumb people to deliver basic messages. Thesystem reads a dumb person’s hand gesture for different variations of hand movement. A processor constantly receives input sensor values and then processes it, then searches for matching message for the set of sensor values. Once it found in memory, the message is retrieved and is spoken out using text to speech processing through the interfaced speaker [1]. Data for this study was collected using structured open and closed questionnaires which were clearly administered to the sample used in my study. Data were analyzed using embedded C software. Finally, the findings were positive to my research objectives and it was expected to help the intended group in the society.
对于有声音障碍的人来说,将他们的信息传达给普通人是非常困难的,因为普通人没有接受过手语训练,沟通变得非常困难。因此,我提出了一个说话系统,使哑巴和聋哑人能够用手势向正常人传达他们的信息。该系统采用手势读取系统,配备连接到每个手指的手势和弯曲传感器,并与扬声器单元一起连接到射频发射器作为输入。这个系统是由电池供电的电路驱动的。此外,这个系统将包含不同的单词和句子,帮助哑巴传递基本信息。该系统可以读取哑巴的手势,以识别不同的手势动作。处理器不断地接收输入的传感器值,然后对其进行处理,然后为传感器值集搜索匹配的消息。一旦在内存中找到,消息就会被检索出来,并通过接口扬声器使用文本到语音处理的方式说出来[1]。本研究的数据是通过结构化的开放式和封闭式问卷收集的,这些问卷明确地适用于我研究中使用的样本。采用嵌入式C软件对数据进行分析。最后,研究结果对我的研究目标是积极的,并有望帮助社会上的预期群体。
