The Fourth Industrial Revolution (4IR) will dramatically change our work and personal lives. New developments in the fields of artificial intelligence, big data and the internet of things (IoT) hold big promise but also present challenges to our entire society. However, only a very small fraction of the population is sufficiently versed in the new technologies to be able to make informed decisions on matters that will affect all our future lives. In addition, many people feel threatened and fear that they will lose their jobs. Even students in the fields of Information Systems (IS) and IT management do not feel familiar with and confident about their ability to navigate the world of 4IR. This study reports on a series of projects that have been undertaken in South Africa to encourage IS/IT students and professionals to embrace IoT technologies and to upskill themselves in this field. The projects have been undertaken from 2016 to 2019 at a South African university, by making use of a makerspace as well as a maker philosophy. Results indicate that the students and professionals were able to increase their skills as well as their confidence and attitude to engage with IoT technology. The contribution of this study is to suggest good practices for the use of IoT and a maker philosophy to prepare students and professionals for the world of 4IR.
第四次工业革命(4IR)将极大地改变我们的工作和个人生活。人工智能、大数据、物联网等领域的新发展给我们带来了巨大的希望,但也给我们整个社会带来了挑战。然而,只有很小一部分人足够精通新技术,能够在影响我们未来生活的问题上做出明智的决定。此外,许多人感到受到威胁,担心他们会失去工作。即使是信息系统(IS)和IT管理领域的学生,也对自己驾驭第四次工业革命世界的能力感到不熟悉和不自信。本研究报告了在南非开展的一系列项目,旨在鼓励IS/IT学生和专业人士接受物联网技术,并提高自己在该领域的技能。这些项目于2016年至2019年在南非的一所大学进行,利用了创客空间和创客理念。结果表明,学生和专业人士能够提高他们的技能,以及他们参与物联网技术的信心和态度。本研究的贡献在于为物联网的使用提出了良好的实践建议,并提出了一种创客理念,让学生和专业人士为第四次工业革命的世界做好准备。

Today cloud computing is the trending technology and has been proven as a viable business model. We can see fastest growth in the recent years because of it’s easy to access mechanism. As the number of cloud users are increasing exponentially, so to handle this, the concept of load balancing is needed to minimize the overhead and maximize the throughput on the cloud. In this paper, we analyze three cloud algorithms namely Round Robin, Throttled, Equally Spread Current Execution Load and their performance in terms of average response time, hourly data center response time and the cost of Virtual Machine (VM) etc. with the help of Cloud Analyst simulator. Cloud Analyst is the simulator which is best among all simulator for algorithm testing in cloud environment. Simulation results demonstrate that Throttled outperforms among these algorithms as number of users increases.
如今,云计算是一种趋势技术,并已被证明是一种可行的商业模式。我们能看到近年来最快的增长,因为它是容易进入的机制。由于云用户的数量呈指数级增长,因此要处理这个问题,需要负载平衡的概念来最小化开销并最大化云上的吞吐量。本文借助cloud Analyst模拟器,分析了轮循(Round Robin)、节流(throttled)、均摊当前执行负载(equarespread Current Execution Load)三种云算法,以及它们在平均响应时间、每小时数据中心响应时间和虚拟机成本等方面的性能。Cloud Analyst是云环境下算法测试的最好的模拟器。仿真结果表明,随着用户数量的增加,节流算法的性能优于这些算法。

The paper analyzes the Coronary Artery Calcium (CAC) score metric with respect to the age and gender of the individual. CAC score fairly predicts the risk of cardiovascular diseases. As there is an upsurge in the number of heart patients every day, cardiac health of a person should never be neglected. The Calcium Score involves a non-invasive CT scan of the heart and keeps track of the amount of calcified plaque in coronary arteries. The paper presents statistical comparisons among the scores obtained for males and females across different age groups. These findings are beneficial to predict early Cardiovascular Diseases and surely be useful as an awareness to maintain a healthy lifestyle.

Swarm Intelligence (SI) is increasing day by day in the various research fields. There are many swarm-based optimizations introduced since the early ’60s, Evolutionary Algorithms (EA) is the most updated one. All Evolutionary Algorithms have proved their capability to resolve most of the optimization problems. These algorithms are using for training the neural networks in this paper. The main difficulty for any optimization problem is selecting the correct values of parameters to get possible results. The main idea to get the best convergence rate and best performance is to vary the parameters of the algorithms. This paper provides a comparison of the most used and essential swarm-based optimization algorithms. Here, comparing the optimization algorithms, Particle Swarm Optimization (PSO), and Multi-Verse Optimization (MVO) before and after tuning the parameters with three different datasets.
群体智能(Swarm Intelligence, SI)在各个领域的研究日益增多。自60年代初以来,有许多基于群体的优化方法被引入,进化算法(EA)是最新的一种。所有的进化算法都证明了它们解决大多数优化问题的能力。本文将这些算法用于神经网络的训练。任何优化问题的主要困难是选择正确的参数值来获得可能的结果。为了获得最佳的收敛速度和最佳的性能,主要思想是改变算法的参数。本文对最常用的和最基本的基于群的优化算法进行了比较。本文比较了粒子群优化算法(PSO)和多重宇宙优化算法(MVO)在三种不同数据集参数调优前后的差异。

Software Effort Estimation (SEE) is an important activity during development and production of software projects. The estimated effort is directly associated with the various planning and financial activities. It is also directly associated with business success. Constructive Cost Model (COCOMO) is a widely accepted SEE model. But in the current development scenario, existing parameters of COCOMO don't give realistic results. In the recent past, many researchers improved the performance of COCOMO by optimizing the parameters with the help of various Nature-Inspired Algorithms (NIAs). In this paper, a recently proposed NIA which is based on the frog's anti-predator behavior is used for the optimizing the parameters of basic COCOMO for SEE of 18 software projects listed in NASA data set. The performance of the Anti-Predatory NIA (APNIA) based proposed approach is also evaluated on NASA18 software data set in terms of the Mean Absolute Error (MAE). The result obtained shows 93.41% improvement in terms of MAE as compared to the basic COCOMO, 40.69% improvement as compared to Genetic Algorithm (GA) and 0.93% improvement as compared to Particle Swarm optimization (PSO) with inertia weight in effort estimation by proposed approach.

Wireless sensor networks (WSN) became very popular in last few years. They are deployed in distributed manner for collecting variety of data. There are a lot of research issues and challenges in WSN viz; energy efficiency, security, localization etc. Outlier or anomaly detection is one of such area to prevent malicious attacks or reducing the errors and noisy data in millions of wireless sensor networks. Outlier detection models should not compromise with quality of data. We have to identify the anomalies in offline mode or online mode with accuracy, better performance and intake of minimal resources in the network. There are various machine learning techniques which have been used by several researchers these days to detect outliers. This paper presents a survey on outlier detection in WSN data using various machine learning techniques.

From the past few years, Generative adversarial networks (GANs) have gained more and more interest of researchers of Artificial Intelligence and this is only due to the reliability on huge amount of data, well designed network architectures and smart training techniques because of which they produce highly realistic pieces of content of images, texts and sounds. The inspirational idea of working in GANs has been derived from game theory, named as the zero–sum game. GANs consist of two components-a generator as well as a discriminator both of which act like two players of the game playing in opposition with each other. This paper focuses on the basic theory and principle mechanism of GANs. Next, the paper discusses few variants based on architecture as well as loss functions of some kinds. Finally, the last section of paper presents few other variants of GANs which are implemented in the field of computer vision and other real world problems. It is found that this area has a wider scope in terms of virtual real interaction and integration along with parallel learning. So it is considered as new implementation area for GANs in the coming future.
在过去的几年里,生成对抗网络(GANs)越来越受到人工智能研究人员的关注,这仅仅是因为它具有大量数据的可靠性、设计良好的网络架构和智能的训练技术,因为它们可以产生高度逼真的图像、文本和声音内容。在gan中工作的灵感来源于博弈论,称为零和游戏。GANs由两个组成部分组成——生成器和鉴别器,两者的作用就像游戏中的两个玩家相互对立。本文重点介绍了gan的基本理论和原理机理。其次,本文讨论了基于体系结构的几种变体以及几种损失函数。最后,论文的最后一部分介绍了在计算机视觉领域和其他现实世界问题中实现的gan的其他几个变体。研究发现,这一领域在虚拟现实的互动和融合以及并行学习方面具有更广泛的应用范围。因此,它被认为是未来gan的一个新的实现领域。

The user’s request changes dynamically in service-based cloud applications, which requires optimal amount of computing resources to meet service-level agreements (SLAs). The existing server-side resource allocation mechanisms have limitations in provisioning the required resources to handle the incoming load on the basis of user’s requests. To overcome the aforementioned situation, cloud computing provides ample amount of computing resources to meet the SLAs. There are possibilities that cloud resources might not be properly utilized and might suffer over and under utilization. In this study, the authors have proposed an autonomic resource allocation framework, that automatically provisions (allocate and deallocate) the required computing resources as per the load. In this study, the proposed model leverages the queuing model to optimize the resource allocation process. The primary goal of this study is to improve the virtual resource utilization and response time with respect to the existing methods. Finally, the results have shown that the response time and resource utilization have been improved.
在基于服务的云应用程序中,用户的请求会动态变化,这需要最优数量的计算资源来满足服务水平协议(sla)。现有的服务器端资源分配机制在根据用户请求提供所需资源以处理传入负载方面存在限制。为了克服上述情况,云计算提供了充足的计算资源来满足sla。云资源可能没有得到适当的利用,可能出现过度利用和利用不足的情况。在这项研究中,作者提出了一个自主资源分配框架,根据负载自动提供(分配和释放)所需的计算资源。在本研究中,提出的模型利用排队模型来优化资源分配过程。本研究的主要目标是提高虚拟资源的利用率和响应时间相对于现有的方法。最后,结果表明,响应时间和资源利用率得到了改善。

Wearable technologies have begun to play an important role in the workplace. This paper presents a Smart PPE (Personal Protective Equipment) solution which employs a sensor network located on a helmet and a belt to monitor the state of the worker and the environment.

An explosion consequence analysis utilizes explosives science and engineering to determine potential hazards to targets through objective processes and scientific evidence. This paper proposes the implementation of adaptive neuro-fuzzy inference system in providing decision support for accurate and effective explosion consequence analysis. The model is trained over data obtained from United Nations SaferGuard platform and incorporates the consequence analysis of seven different types of explosives, on brick structures over a range of twenty meters. The model has been implemented using block diagrams on MATLAB Simulink. This work adds to the body of evidence that soft computing techniques can be implemented in designing accurate artificial intelligence decision support and expert systems for both military and civilian applications.
爆炸后果分析是利用爆炸科学与工程,通过客观过程和科学证据来确定对目标的潜在危害。本文提出实现自适应神经模糊推理系统,为准确有效的爆炸后果分析提供决策支持。该模型是根据从联合国安全保卫平台获得的数据进行训练的,并结合了对20米范围内砖结构上七种不同类型爆炸物的后果分析。该模型已在MATLAB Simulink中使用方框图实现。这项工作增加了软计算技术可以在军事和民用应用中设计精确的人工智能决策支持和专家系统的证据。
