In recent years, especially in the context of covid health care development, we have seen that a less amount of medical facility gotten to a patient. To track a few individual data at home like temperature, pulse rate and heart beats of the patients and inform the doctors in case of any patient emergency. To track this data doctor needs a platform to see that data like temperature of patient's body, what's the heart rate of patient for this we are using Thing speak server using this doctor can see the condition of patient. This platform where users can display records in real-time basis. In this paper we discussed health monitoring frameworks that allows patients to be supervised without the need to consult a physician who can be using with market sensors. This module provides the necessary opportunity for a day-to-day paramedic company that can be recorded by a doctor and can receive a notice anyway in an emergency. This field position is most commonly used while the patient is under normal examination or under long-term home care. To measure heart rate usually use a heartbeat sensor but this system will use an AD8232 sensor that will display a patient's Electrocardiograph using the IoT system. Our project proposes a flexible health monitoring system with Electrocardiograph modifications.

Abstract Preoperatively diagnosis of colon rupture due to blunt abdominal trauma is difficult. This can lead to delay in treatment, subsequently resulting in increased morbidity and mortality. We present a case of subserosal ruptured sigmoid colon in a 51-year-old man, diagnosed early by carefuly physical examination and highly suggestive findings on CT scan. We suggest that CT scan is the most valuable tool to diagnose hollow visceral rupture after blunt abdominal trauma. In addition to the established value of finding free air in the peritoneal cavity, it also reveals the site of a rupture or a suspected rupture.

Authors: Almayyan Waheeda , Alzayed Asaad
Published: June 2022

Social networking services – such as Facebook.com and Twitter.com – are fast-growing enterprise platform that has become a prevalent and essential component of daily life. Due to its popularity, Twitter draws many spammers or other fake accounts to post malicious links and infiltrate legitimate users' accounts with many spam messages. Therefore, it is crucial to recognize and screen spam tweets and spam accounts. As a result, spam detection is highly needed but still a difficult challenge. This article applied several Bio-inspired optimization algorithms to reduce the features' dimensions in the first stage. Then we used several classification schemes in the second stage to enhance the spam detection rate in three real Twitter data collections. The performance of the chosen classifiers also revealed that Random Forest and C4.5 classifiers achieved the highest Accuracy, Precision, Recall, and F1-score even on class imbalance.

A New Security Boundary of Component Differentially Challenged XOR Pufs Against Machine Learning Modeling Attacks
Authors: Li Gaoxiang , T. Mursi Khalid , O. Aseeri Ahmad , S. Alkatheiri Mohammed , Zhuang Yu
Published: June 2022

Physical Unclonable Functions (PUFs) are promising security primitives for resource-constrained network nodes. The XOR Arbiter PUF (XOR PUF or XPUF) is an intensively studied PUF invented to improve the security of the Arbiter PUF, probably the most lightweight delay-based PUF. Recently, highly powerful machine learning attack methods were discovered and were able to easily break large-sized XPUFs, which were highly secure against earlier machine learning attack methods. Component-differentially-challenged XPUFs (CDC-XPUFs) are XPUFs with different component PUFs receiving different challenges. Studies showed they were much more secure against machine learning attacks than the conventional XPUFs, whose component PUFs receive the same challenge. But these studies were all based on earlier machine learning attack methods, and hence it is not clear if CDC-XPUFs can remain secure under the recently discovered powerful attack methods. In this paper, the two current most powerful two machine learning methods for attacking XPUFs are adapted by fine-tuning the parameters of the two methods for CDCXPUFs. Attack experiments using both simulated PUF data and silicon data generated from PUFs implemented on field-programmable gate array (FPGA) were carried out, and the experimental results showed that some previously secure CDC-XPUFs of certain circuit parameter values are no longer secure under the adapted new attack methods, while many more CDC-XPUFs of other circuit parameter values remain secure. Thus, our experimental attack study has re-defined the boundary between the secure region and the insecure region of the PUF circuit parameter space, providing PUF manufacturers and IoT security application developers with valuable information in choosing PUFs with secure parameter values.
A Class-based Adaptive QoS Control Scheme Adopting Optimization Technique over WLAN SDN Architecture
Authors: Vanitchasatit Pacharakit , Sanguankotchakorn Teerapat
Published: June 2022

Recently, Software-Defined Networking (SDN), a network architecture approach that enables the network to be intelligently and centrally controlled by using software applications, has been introduced. Another important issue in the network management context is Quality of Service (QoS). This work investigates the QoS provisioning of various traffic classes on an SDN-enabled network. We propose and implement the class-based adaptive QoS control scheme on SDN-enabled network for various traffic classes, namely VoIP, Video Streaming and File Transfer. The effectiveness of our proposed scheme is validated by simulation using Mininet and Ryu controller. The procedure to create the simulation platform and all details relevant to all software used are described step-by-step in detail. The main performance evaluation metric is the Maximum Number of Traffic Flows admittable with QoS while Average Throughput, Latency, Jitter, and Packet Loss Rate are maintained at the comparable level of the existing work in the literature called JMABC [11]. Our simulation results are illustrated with 95% confidence interval. According to the simulation results, it is obvious that our proposed class-based adaptive QoS control scheme adopting the optimization technique significantly outperforms the existing similar QoS provision scheme in terms of the maximum number of the high priority traffic flows (VoIP) admittable with QoS while the other evaluation metrics are maintained at the same level.
Constellation Shared Multiple Access - A Noma Scheme for Increased User Capacity in 5G MMTC
Authors: V. Shanbhag Kiran , H. M. Savitha
Published: June 2022

While the legacy cyclic prefix orthogonal frequency division multiple access is retained as the preferred multiple access scheme for 5G enhanced mobile broadband the research is now focussed on the multiple access schemes for massive machine type communication (mMTC) and ultra-reliable low latency communication .Though orthogonal multiple access schemes provide simple reception, they limit number of simultaneous user equipment as against the primary requirement of mMTC. On the other hand, the various non-orthogonal multiple access schemes which have been proposed so far as the likely solution, need complex successive interference cancellation receivers. So a simplified scheme named constellation shared multiple access is proposed here which substantially increases the number of simultaneous users to be served within a single resource block (RB) in LTE or 5G New Radio, thus aiding the massive connectivity requirement of mMTC. This is achieved by differentiating among the users in constellation domain. Moreover, the simple architecture compatible with 5G eMBB makes it a strong contender multiple access contender for 5G mMTC.
UAV Path Planning using Genetic Algorithm with Parallel Implementation
Authors: AlRaslan Mohammad , Hilal AlKurdi Ahmad
Published: June 2022

The objective of path planning algorithms is to find the optimal path from a source position to a target position. This paper proposes a real-time path planner for UAVs based on the genetic algorithm. The proposed approach does not identify any specific points outside or between obstacles to solve the problems of the invisible path. In addition, this approach uses no additional steps in the genetic algorithm to handle the problems resulting from generating points inside the obstacles, or the intersection between path segments with obstacles. For these reasons, this paper introduces a simple evaluation method that takes into account the intersections between the path segments and obstacles to find a collision-free and near to optimal path. This evaluation method take into account overlapped and intersected obstacles. The sequential implementation for all of the genetic algorithm steps is detailed. This paper explores the Parallel Genetic Algorithms (PGA) models and introduces the parallel implementation of the proposed path planner on multi-core processors using OpenMP. The execution time of the proposed parallel implementation is reduced compared to sequential execution.
Building Reliable Cloud Systems through Chaos Engineering
Authors: Zimba Yolam
Published: June 2022

Cloud computing systems need to be reliable so that they can be accessed and used for computing at any given point in time. The complex nature of cloud systems is the motivation to conduct research in novel ways of ensuring that cloud systems are built with reliability in mind. In building cloud systems, it is expected that the cloud system will be able to deal with high demands and unexpected events that affect the reliability and performance of the system. In this paper, chaos engineering is considered a heuristic method that can be used to build reliable cloud systems. Chaos engineering is aimed at exposing weaknesses in systems that are in production. Chaos engineering will help identify system weaknesses and strengths when a system is exposed to unexpected knocks and shocks while it is in production. Chaos engineering allows system developers and administrators to get insights into how the cloud system will behave when it is exposed to unexpected occurrences.
An Evaluation of Security in Blockchain-based Sharing of Student Records in Higher Education
Authors: Arndt Timothy , Guercio Angela , Chae Younghun
Published: June 2022

Blockchain has recently taken off as a disruptive technology, from its initial use in cryptocurrencies to wider applications in areas such as property registration and insurance due to its characteristic as a distributed ledger which can remove the need for a trusted third party to facilitate transactions. This spread of the technology to new application areas has been driven by the development of smart contracts – blockchain-based protocols which can automatically enforce a contract by executing code based on the logic expressed in the contract. One exciting area for blockchain is higher education. Students in higher education are ever more mobile, and in an ever more agile world, the friction and delays caused by multiple levels of administration in higher education can cause many anxieties and hardships for students as well as potential employers who need to examine and evaluate student credentials. Distance learning as a primary platform for higher education promises to open up higher education to a wider range of learners than ever before. Blockchain-based storage of academic credentials is being widely studied due to the advantages it can bring. As with any network-based system, blockchain comes with a number of security and privacy concerns. Blockchain needs to meet several security-related requirements to be widely accepted: decentralization; confidentiality; integrity; transparency; and immutability. Researchers have been busy devising schemes to ensure that such requirements can be met in blockchain-based systems. Several types of blockchain-specific attacks have been identified: 51% attacks; malicious contracts; spam attacks; mining pools; targeted DDoS attacks; and others. Real-world attacks on blockchain-based systems have been seen on cryptocurrency sites. In this paper, we will evaluate the specific privacy and security concerns for blockchain-based systems used for academic credentials as well as suggested solutions. We also examine the issues for academic credentials which are stored “off-chain” in such systems (as is often the case). In this case, a Distributed File System (DFS) implemented with a peer-to-peer (P2P) architecture is often the choice for the storage of the academic credentials since it matches the decentralized nature of blockchain. Blockchain then contributes much to the usefulness of such a DFS, making it in turn a good match for a P2P DFS such as IPFS.

Published: June 2022

There have been many solutions proposed to increase the ability to detection of malware in executable files in general and in Portable Executable files in particular. In this paper, we rely on the PE header structure of Portable Executablefiles to propose another approach in using Machine learning to classify these files, as malware files or benign files. Experimental results show that the proposed approach still uses the Random Forest algorithm for the classification problem but the accuracy and execution time are improved compared to some recent publications (accuracy reaches 99.71%).

Published: June 2022

Open-source enterprise resource planning (ERP) software has become a preferred alternative for modern organizations due to its affordable cost, availability and ease of access. Open-source software allows access to customizable code which in most instances may have security loop holes due to the nature of its releases. The study is motivated by need for accountability and security assurance by stakeholders and the need for justification of investments towards information security. The objective was to analyse security indicators for open-source resource planning software. Papers and journals published between 2017 and 2021 from IEEE, ACM, Springer, arXiv, Wiley online library and EBSCO were reviewed. Out of the publications generated through the Google search, 62 publications were selected by reading the title, abstract, introduction and full text. Results indicate un-updated software, full access rights, inadequate training, failure to comply, single authentication and unauthorized software as some of the factors that indicate open-source enterprise resource planning software security. In conclusion effectiveness of mitigation measures to address these factors shows security or insecurity. Notably, there is need to institute security control measures and metrics for the identified factors to help assess security posture of enterprises during ERP software implementation. We recommend the design of security a measurement framework and definition of a metrics suite for assessing open-source ERP software security.

Published: June 2022

Model-Driven Development and the Model-Driven Architecture paradigm have in the recent past been emphasizing on the importance of good models. In the Object-Oriented paradigm one of the key artefacts are the Statechart diagrams. Statechart diagrams have inherent complexity which keeps increasing every time the diagrams are modified, and this complexity poses problems when it comes to comprehending the diagrams. Statechart diagrams provide a foundation for analysing the dynamic behaviour of systems, and therefore, their quality should be maintained. The aim of this study is to develop and validate metrics for measuring the complexity of UML Statechart diagrams. This study used design science which involved the definition of metrics, development of a metrics tool, and theoretical and empirical validation of the metrics. For the measurement of the cognitive complexity of statechart diagrams, this study proposes three metrics. The defined metrics were further used to calculate the complexity of two sample statechart diagrams and found relevant. Also, theoretical validation of the defined metrics was done using the Weyuker’s nine properties and revealed they are mathematically sound. Empirical validations were performed on the metrics and results indicate that all the three metrics are good for the measurement of the cognitive complexity of statecharts.

Authors: Rochanah Rochanah
Published: June 2022

It is hard to argue that religion has a role in triggering the occurrence of violence that occurs between religious communities. The mistake of Muslims in understanding religion has resulted in Islam showing a radical face. The negative label probably needs to be re-aligned so that the image of Islam returns to its good nature according to its essence. In this case, students as intellectuals have a big role in straightening it out. The aim of this study analyse the students’ perceptions of islamic religious education about islam and radicalism: a study of three PTKIN central Java. This research is a field research with a descriptive analytical qualitative approach. Data collection techniques were carried out through observation, interviews and documentation. The results showed that the current situation of Muslims has not been able to properly practice their religious teachings so that what is practiced in their daily lives does not run in harmony with what is contained in the Qur'an. This is the initial cause of the emergence of acts of violence in the name of religion. In reality, radicalism is shown in dishumanist actions that appear in several tragedies framed in the name of religion. This raises the perception that Islam is a radical religion. However, Muslims must prove that the negative label directed at Islam is a very baseless argument because Islam is not a terrorist religion and all actions that lead to acts of terror are not essentially Islamic teachings.

The dialectic of memory and habit: The situation in the 21st century architecture
Authors: Rappaport Alexander
Published: June 2022

The author’s two articles are united by the theme of the fate of modern architecture in the context of social changes. The first one analyses the dynamics of history, the change in the rhythm of interpretation of its course, and the mal-synchronization of changes in the world and people. The pace of renewal is organically connected with the pace of habituation. Accordingly, the arguments for or against the preservation or change can also radically change. The de-synchronization of historical changes is a problem which can be solved by architecture and urban planning.
