Internet of Things (IoT) is one of the famous applications of internet commuting and of cloud computing, and it is a widely used applications by organizations or by individuals, i.e., smart city, smart home, etc. There are many different IoT platforms that have been developed and used by IoT cloud providers to provide services to their subscribers. These different platforms lead to difficulty understand of each platform by developers. So, the need of IoT standard system is highly required to mitigate the diversity of building IoT-based system using different software layers. In this paper, a unified IoT-based architecture has been proposed based on 7-layers framework to be as a de facto standard to the most of IoT-based applications. Moreover, the proposed architecture has been applied using the car accident system which is a known application of IoT based application using CubCarbon Wireless Senser Networks (WSN) simulator. The proposed architecture shows the consistency between its 7-layers and promising to be as a considered unified IoT architecture.
物联网(Internet of Things, IoT)是互联网通勤和云计算的著名应用之一，是一种广泛应用于组织或个人的应用，即智慧城市、智能家居等。物联网云提供商已经开发并使用了许多不同的物联网平台来为其用户提供服务。这些不同的平台导致开发人员难以理解每个平台。因此，对物联网标准体系的需求提出了很高的要求，以减轻使用不同软件层构建物联网系统的多样性。本文提出了一个基于7层框架的统一物联网架构，作为大多数物联网应用的事实上的标准。此外，所提出的架构已应用于车祸系统，该系统是使用CubCarbon无线传感器网络(WSN)模拟器的物联网应用的已知应用。提出的架构显示了其7层之间的一致性，并有望成为一个被认为是统一的物联网架构。

Exploratory data analysis is a data visualization approach used to extract knowledge from raw data. This approach can be applied to medical data to improve healthcare providers services. In recent years, breast cancer has become more common in women and requires effective procedures to detect it in the early stage. In this context, breast cancer patients' data were collected from the Sebha oncology center through their routine blood tests. The exploratory data analysis technique is used in this study to better analyze the patients' markers. The analysis aims to discover prominent bio and tumor markers that can assist in determining whether a tumor is benign or malignant. Several statistical and visualizations methods are used. The results show that the most effective markers that may be used as cancer predictors are: Cancer Antigen-15.3, Carcinoma Embryonic Antigen, White Blood Cells, Blood platelets, and Albumin. These findings are consistent with the findings of Sebha oncology center specialists. which may eventually aid in their cancer diagnosis.

On-Street parking characterizes most urban streets, especially in the urban centers where it is considered an attractive facility for drivers. However, inappropriate on-street parking could adversely affect the capacity and the driving speeds of the adjacent road and can cause severe delays, especially on busy roads. In addition, it can pose danger to the safety of road users if not managed properly. This paper tries to study and analyze the car parking on El-Wasea Street in Sebha city, and its impact on traffic behavior. The study reveals that parking on the street does not follow any kind of order, parking spaces are not appropriately provided for parking, and in some places along the street parking took parts of traffic lanes endangering traffic safety, especially during peak hours. The paper included some recommendations on how to rearrange the On-street parking on El-Wasea Street, which is expected to solve parking of cars, or at least mitigate, the adverse impacts of parking on the traffic movement on the street.

Government agencies and transportation engineers use pavement management systems (PMS) to evaluate pavement performance and keep pavement above the minimum acceptable performance standards. The Pavement Condition Index (PCI) and the international roughness index (IRI) are among the most commonly used indices to evaluate pavement conditions. Due to IRI data collection being more accessible and less expensive than collecting pavement distress data, this study aims to develop PCI models that can successfully estimate the PCI values based on IRI for flexible pavement using two Machine Learning techniques (ML), namely: Random Forest (RF), and Support Vector Machine (SVM), and three conventional techniques, namely: linear, quadratic, and cubic regression. The study was carried out with the database collected from the Long-Term Pavement Performance (LTPP) program. The results of the dataset reveal that both ML models (RF and SVM) have strong prediction ability with high values of coefficient of determination (R^2 = 99.7 and 96.8) %, and low values of Root Mean Squared Error (RMSE = 1.095 and 3.569) % and Mean Absolute Error (MAE = 0.474 and 2.244). In conclusion, the goodness of fit of the proposed ML models was compared with conventional techniques models previously developed. The results showed that the ML models yielded higher prediction accuracy than conventional techniques.

The cache coherence problem is the challenge of keeping multiple cache synchronized when one of the processors update its local copy of data which is shared among multiple cache. This paper discusses several different varieties of cache coherence protocols including with their pros and cons, and using simulation technique it will address this problem and compare between two protocols that use to solve it: Directory-based protocol and Snooping protocol. Simulation results have shown that snooping based systems are appropriate for high bandwidth systems while directory-based cache coherence protocols are suitable for lower bandwidth systems.

Reactive Powder Concrete (RPC) is a combined material that will allow the concrete industry to enhance material consumption, produce economic benefits, be more durable, and be more environmentally friendly. Due to the highly dense microstructure of RPC, it performs poorly at high temperatures due to the formation of high pore pressure, which causes material breakdown. This paper demonstrates the outcomes of an investigational study of the behavior of six RPC mixes incorporating hybrid steel and plastic waste (polypropylene) fibers after being subjected to high temperatures of up to 500 ºC. Residual compressive strength, residual splitting strength, and density were performed for all the RPC mixes. The results demonstrate that the drop in the compressive strength of RPC is greater than the reduction in their corresponding splitting strength. Furthermore, within a temperature range of about 500 ºC, this mechanical strength showed a noticeable decrease. The decrement of splitting strength ranged between about 8% to 33% . Steel and polypropylene fibers also improve the residual strength of RPC samples. On the basis of these results, a mix containing mixed fibers (25 % steel and 75 % polypropylene) is recommended as appropriate for extreme temperature applications.

On the basis of these results, a mix containing mixed fibers (25 % steel and 75 % polypropylene) is recommended as appropriate for extreme temperature applications.","PeriodicalId":16911,"journal":{"name":"Journal of Pure & Applied Sciences","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83496118","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}
