  • Self-supervised Learning: A Succinct Review

    • Free pre-print version: Loading...

      Abstract: Abstract Machine learning has made significant advances in the field of image processing. The foundation of this success is supervised learning, which necessitates annotated labels generated by humans and hence learns from labelled data, whereas unsupervised learning learns from unlabeled data. Self-supervised learning (SSL) is a type of un-supervised learning that helps in the performance of downstream computer vision tasks such as object detection, image comprehension, image segmentation, and so on. It can develop generic artificial intelligence systems at a low cost using unstructured and unlabeled data. The authors of this review article have presented detailed literature on self-supervised learning as well as its applications in different domains. The primary goal of this review article is to demonstrate how images learn from their visual features using self-supervised approaches. The authors have also discussed various terms used in self-supervised learning as well as different types of learning, such as contrastive learning, transfer learning, and so on. This review article describes in detail the pipeline of self-supervised learning, including its two main phases: pretext and downstream tasks. The authors have shed light on various challenges encountered while working on self-supervised learning at the end of the article.

  • Molecular Mechanics of Disordered Solids

    • Free pre-print version: Loading...

      Abstract: Abstract Disordered solids are ubiquitous in engineering and everyday use. Although research has made considerable progress in the last decades, our understanding of the mechanics of these materials is, at best, in an embryonic state. Since the nature of disorder complicates the realization of physically meaningful continuum-mechanical models, particle-based molecular descriptions provide a powerful alternative. This paper reviews the numerical realization of classical molecular dynamics from an engineer’s perspective, starting with selecting potential functions, boundary conditions, time integration, and thermodynamic ensembles. Then, we discuss the concept of the potential energy landscape and the computational realization of the most suitable minimization methods. Subsequently, we discuss the algorithms necessary to numerically generate disordered materials, considering their thermodynamic properties and structural identification. We comprehensively and critically review computational methods and strategies available to mimic disordered materials on a molecular level and discuss some intriguing phenomena that are, to date, mostly ignored when applying models based on continuum-mechanical frameworks. We present the crucial difference between the shear response of a crystalline and a disordered structure. In this context, we elaborate on why it is beneficial to use an overdamped, athermal description to disentangle the complex deformation mechanics of disordered solids and comprehensively discuss the theory of the mechanics of disordered materials, including the problems of prediction and reversibility. Furthermore, we examine the fracture process on the nanoscale and investigate the response behavior to more complex deformation protocols. Finally, we provide critical conclusions, including challenges and future perspectives for engineers.

  • The Augmented Lagrangian Method as a Framework for Stabilised Methods in
           Computational Mechanics

    • Free pre-print version: Loading...

      Abstract: Abstract In this paper we will present a review of recent advances in the application of the augmented Lagrange multiplier method as a general approach for generating multiplier-free stabilised methods. The augmented Lagrangian method consists of a standard Lagrange multiplier method augmented by a penalty term, penalising the constraint equations, and is well known as the basis for iterative algorithms for constrained optimisation problems. Its use as a stabilisation methods in computational mechanics has, however, only recently been appreciated. We first show how the method generates Galerkin/Least Squares type schemes for equality constraints and then how it can be extended to develop new stabilised methods for inequality constraints. Application to several different problems in computational mechanics is given.

  • State-of-the-Art Load Balancing Algorithms for Mist-Fog-Cloud Assisted
           Paradigm: A Review and Future Directions

    • Free pre-print version: Loading...

      Abstract: Abstract The rapid growth of IoT devices leads to increasing requests. These tremendous requests cannot be processed by IoT devices due to the computational power of IoT devices and the disparate requirements of requests. Cloud computing seemed appealing to service these requests due to its remarkable characteristics. However, the physical gap between the Cloud datacenter and IoT devices causes a huge latency overhead. Furthermore, the centralized datacenter also experiences tremendous power consumption. Therefore, the Fog computing layer is introduced as a complementary layer to Cloud computing in between the IoT and the Cloud layer. Fog computing appears as cutting-edge technology to leverage the large computations in the Fog layer, thereby minimizing the latency gap and the power consumption of the datacenters. A Mist layer is placed in between the Fog and IoT layer to enable routing of the requests to Fog nodes and Cloud virtual machines. Many articles propose different load balancing strategies to distribute the loads uniformly in both Fog and Cloud layers. This contribution considers a wide spectrum of reviews as well as research articles into consideration ranging from 2010 to 2022. Besides, a layered architecture is proposed considering the IoT, Mist, Fog, and Cloud layers. Furthermore, research queries are analyzed and answered about the load balancing for these evolving paradigms, critical issues and challenges, and future directions. It is believed that this contribution would be a helping hand for the nascent researchers to get an insight into evolving paradigms, algorithms, issues, challenges, and future directions.

  • A Review of Image-Based Simulation Applications in High-Value
           Manufacturing

    • Free pre-print version: Loading...

      Abstract: Abstract Image-Based Simulation (IBSim) is the process by which a digital representation of a real geometry is generated from image data for the purpose of performing a simulation with greater accuracy than with idealised Computer Aided Design (CAD) based simulations. Whilst IBSim originates in the biomedical field, the wider adoption of imaging for non-destructive testing and evaluation (NDT/NDE) within the High-Value Manufacturing (HVM) sector has allowed wider use of IBSim in recent years. IBSim is invaluable in scenarios where there exists a non-negligible variation between the ‘as designed’ and ‘as manufactured’ state of parts. It has also been used for characterisation of geometries too complex to accurately draw with CAD. IBSim simulations are unique to the geometry being imaged, therefore it is possible to perform part-specific virtual testing within batches of manufactured parts. This novel review presents the applications of IBSim within HVM, whereby HVM is the value provided by a manufactured part (or conversely the potential cost should the part fail) rather than the actual cost of manufacturing the part itself. Examples include fibre and aggregate composite materials, additive manufacturing, foams, and interface bonding such as welding. This review is divided into the following sections: Material Characterisation; Characterisation of Manufacturing Techniques; Impact of Deviations from Idealised Design Geometry on Product Design and Performance; Customisation and Personalisation of Products; IBSim in Biomimicry. Finally, conclusions are drawn, and observations made on future trends based on the current state of the literature.

  • Explainable Methods for Image-Based Deep Learning: A Review

    • Free pre-print version: Loading...

      Abstract: Abstract With Artificial Intelligence advancement, Deep neural networks (DNN) are extensively used for decision-making in intelligent systems. However, improved performance and accuracy have been achieved through the increasing use of complex models, which makes it challenging for users to understand and trust. This ambiguous nature of these Deep machine learning models of high accuracy and low interpretability is problematic for their adoption in critical domains where it is vital to be able to explain the decisions made by the system. Explainable Artificial Intelligence has become an exciting field for explaining and interpreting machine learning models. Among the different data types used in machine learning, image data is considered hard to train because of the factors such as class, scale, viewpoint, and background variations. This paper aims to provide a rounded view of emerging methods to explain DNN models as a way to boost transparency in image-based deep learning with the analysis of the current and upcoming trends.

    • Free pre-print version: Loading...

      Abstract: Abstract Meta-heuristic algorithms have a high position among academic researchers in various fields, such as science and engineering, in solving optimization problems. These algorithms can provide the most optimal solutions for optimization problems. This paper investigates a new meta-heuristic algorithm called Slime Mould algorithm (SMA) from different optimization aspects. The SMA algorithm was invented due to the fluctuating behavior of slime mold in nature. It has several new features with a unique mathematical model that uses adaptive weights to simulate the biological wave. It provides an optimal pathway for connecting food with high exploration and exploitation ability. As of 2020, many types of research based on SMA have been published in various scientific databases, including IEEE, Elsevier, Springer, Wiley, Tandfonline, MDPI, etc. In this paper, based on SMA, four areas of hybridization, progress, changes, and optimization are covered. The rate of using SMA in the mentioned areas is 15, 36, 7, and 42%, respectively. According to the findings, it can be claimed that SMA has been repeatedly used in solving optimization problems. As a result, it is anticipated that this paper will be beneficial for engineers, professionals, and academic scientists.

      Abstract: Abstract Software development analytics is a research area concerned with providing insights to improve product deliveries and processes. Many types of studies, data sources and mining methods have been used for that purpose. This systematic literature review aims at providing an aggregate view of the relevant studies on Software Development Analytics in the past decade, with an emphasis on its application in practical settings. Definition and execution of a search string upon several digital libraries, followed by a quality assessment criteria to identify the most relevant papers. On those, we extracted a set of characteristics (study type, data source, study perspective, development life-cycle activities covered, stakeholders, mining methods, and analytics scope) and classified their impact against a taxonomy. Source code repositories, exploratory case studies, and developers are the most common data sources, study types, and stakeholders, respectively. Testers also get moderate attention from researchers. Product managers’ concerns are being addressed frequently and project managers are also present but with less prevalence. Mining methods are rapidly evolving, as reflected in their identified long list. Descriptive statistics are the most usual method followed by correlation analysis. Being software development an important process in every organization, it was unexpected to find that process mining was present in only one study. Most contributions to the software development life cycle were given in the quality dimension. Time management and costs control were less prevalent. The analysis of security aspects is even more reduced, however, evidences suggest it is an increasing topic of concern. Risk management contributions are also scarce. There is a wide improvement margin for software development analytics in practice. For instance, mining and analyzing the activities performed by software developers in their actual workbench, i.e., in their IDEs. Together with mining developers’ behaviors, based on the evidences and trend, in a short term period we expect an increase in the volume of studies related with security and risks management.

  • Systematic Fitting and Comparison of Hyperelastic Continuum Models for
           Elastomers

    • Free pre-print version: Loading...

      Abstract: Abstract Hyperelasticity is a common modeling approach to reproduce the nonlinear mechanical behavior of rubber materials at finite deformations. It is not only employed for stand-alone, purely elastic models but also within more sophisticated frameworks like viscoelasticity or Mullins-type softening. The choice of an appropriate strain energy function and identification of its parameters is of particular importance for reliable simulations of rubber products. The present manuscript provides an overview of suitable hyperelastic models to reproduce the isochoric as well as volumetric behavior of nine widely used rubber compounds. This necessitates firstly a discussion on the careful preparation of the experimental data. More specific, procedures are proposed to properly treat the preload in tensile and compression tests as well as to proof the consistency of experimental data from multiple experiments. Moreover, feasible formulations of the cost function for the parameter identification in terms of the stress measure, error type as well as order of the residual norm are studied and their effect on the fitting results is illustrated. After these preliminaries, invariant-based strain energy functions with decoupled dependencies on all three principal invariants are employed to identify promising models for each compound. Especially, appropriate parameter constraints are discussed and the role of the second invariant is analyzed. Thus, this contribution may serve as a guideline for the process of experimental characterization, data processing, model selection and parameter identification for existing as well as new materials.

      Abstract: Abstract The intricacy of the real-world numerical optimization tribulations has full-fledged and diversely amplified necessitating proficient yet ingenious optimization algorithms. In the domain wherein the classical approaches fall short, the predicament resolving nature-inspired optimization algorithms (NIOA) tend to hit upon an excellent solution to unbendable optimization problems consuming sensible computation time. Nevertheless, in the last few years approaches anchored in nonlinear physics have been anticipated, announced, and flourished. The process based on non-linear physics modeled in the form of optimization algorithms and as a subset of NIOA, in countless cases, has successfully surpassed the existing optimization methods with their effectual exploration knack thus formulating utterly fresh search practices. Archimedes Optimization Algorithm (AOA) is one of the recent and most promising physics optimization algorithms that use meta-heuristics phenomenon to solve real-world problems by either maximizing or minimizing a variety of measurable variables such as performance, profit, and quality. In this paper, Archimedes Optimization Algorithm (AOA) has been discussed in great detail, and also its performance was examined for Multi-Level Thresholding (MLT) based image segmentation domain by considering t-entropy and Tsallis entropy as objective functions. The experimental results showed that among recent Physics Inspired Optimization Algorithms (PIOA), the Archimedes Optimization Algorithm (AOA) produces very promising outcomes with Tsallis entropy rather than with t-entropy in both color standard images and medical pathology images.

  • Review of the High-Order TENO Schemes for Compressible Gas Dynamics and
           Turbulence

    • Free pre-print version: Loading...

      Abstract: Abstract For compressible flow simulations involving both turbulence and shockwaves, the competing requirements render it challenging to develop high-order numerical methods capable of capturing the discontinuities sharply and resolving the turbulence with high spectral resolution. In particular when deployed with the advanced large-eddy simulation (LES) approach, for which the governing equations are solved with coarse meshes, the solution is extraordinarily sensitive to the numerical dissipation resulting in large uncertainties for cross-code comparisons. Similar sensitivities have also been observed for a wide range of complex fluid predictions, e.g., turbulent reacting flows, two-phase flows, and transitional flows. In this paper, the family of high-order targeted essentially non-oscillatory (TENO) schemes on both the Cartesian and unstructured meshes is reviewed for general hyperbolic conservation laws with an emphasis on the high-speed turbulent flows. As a novel variant of popular weighted ENO (WENO) scheme, the TENO scheme retains the sharp shock-capturing capability of WENO and is suitable for resolving turbulence with controllable low numerical dissipation. The key success of TENO relies on a strong scale-separation procedure and the tailored novel ENO-like stencil selection strategy. In addition, the built-in candidate stencils with incremental width facilitate the construction of arbitrarily high-order (both odd- and even-order) schemes featuring superior robustness. Detailed performance comparisons between the WENO and TENO schemes are discussed comprehensively as well as the applications of TENO schemes to challenging compressible fluids. At last, the potential future developments to further boost the performance of TENO schemes from various perspectives are highlighted.

  • A Review of Deep Transfer Learning Approaches for Class-Wise Prediction of
           Alzheimer’s Disease Using MRI Images

    • Free pre-print version: Loading...

      Abstract: Abstract Alzheimer's disease is an irreversible, progressive neurodegenerative disorder that destroys the brain and memory functionalities. In Alzheimer's disease, the brain starts shrinking, and over time it converts into dementia. The diagnosis of dementia takes an ample amount of time, around 2.8 to 4.4 years after the first clinical symptoms arise. Alzheimer's disease cannot be cured by any pharmacologic therapies (drugs) now on the market. Alzheimer's disease can only be avoided by early detection and prompt treatment. This paper proposes deep transfer learning models and MRI (Magnetic Resonance Imaging) images to detect the multiple stages of Alzheimer's disease such as "Very-Mild -Demented," "Mild-Demented," "Moderate-Demented," and "No-Demented." Data preprocessing and augmentation process are applied, enabling the model to detect the correct class of Alzheimer's disease. Then further deep transfer learning models (Resnet50, VGG19, Xception, DenseNet201, and EfficientNetB7) are used to classify and predict the early stages of Alzheimer's disease. It is observed that the DenseNet201 model performs the best, with a validation accuracy of 96.59%. The performance of Resnet50, VGG19, Xception, and EfficientNetB7 models was also recorded with validation accuracy of 93.52%, 95.08%, 89.77%, and 83.20%, respectively. The probability curve is then measured and the class-wise prediction of Alzheimer's disease is recorded using the area under curves and receiver operating curve (AUC-ROC) in order to analyze it more deeply.

  • An Extensive Data-Based Assessment of Optimization Techniques for
           Distributed Generation Allocation: Conventional to Modern

    • Free pre-print version: Loading...

      Abstract: Abstract Distributed generation (DG) is a comprehensive, compact, and salient segment of the centralized power system due to its extensive prospective benefits in constrained/unconstrained power quality parameters. Traditional power plants have their own technical, environmental, and economic diminutions for the expansion of power generation in the distribution network. Furthermore, unreserved fossil fuel escorted the electricity companies towards the renewable resources of energy generation. The enhancement of power quality parameters, cost-saving, and fulfilling the energy demand can be achieved by the integration of optimized DG in the distribution network. This paper presents the conventional to modern mathematical approaches enacted for the objective variables’ empowerment via optimization of size and location of DG. The optimization intricacies, parameters, constraints, and benefits are also highlighted in this paper. The exhaustive data-based assessment carried out in this paper is a new work in the literature.

  • Review of Protocol Stack Development of Flying Ad-hoc Networks for
           Disaster Monitoring Applications

    • Free pre-print version: Loading...

      Abstract: Abstract When disasters such as floods or earthquakes occur, we may not have a support of regular infrastructure based networks. This proves fatal because people who are trapped can not be easily located by search and rescue team. In such cases, airborne network consisting of miniaturized drones can be extremely beneficial in providing quick and effective coverage of the affected area, in an on-demand manner providing instant insights to rescue teams. While the challenges offered by such networks are plenty, the ongoing research and development shows promise to make such a technology more reliable and effective. In this paper, we discuss various disaster events in which network of drones can play a vital role in offering support to rescue operations. Mainly, the article discusses the protocols proposed by researchers for various layers of protocol stack including physical layer, data link layer, network layer, transport layer, application layer along with clustering protocols, time synchronization protocols and localization protocols. Finally, a brief summary of software simulation platforms and testbeds, along with future trends of Flying Ad-hoc networks have been provided.
