This special issue of Engineering Analysis with Boundary Elements will be devoted to theory and applications related to mesh reduction methods for wave propagation and scattering analysis. Wave propagation and scattering problems appear in a broad range of science and engineering fields. Although computational wave propagation analysis has a long history of development, there seems to be a recent resurgence in their popularity. Wave motion problems in complex medium and boundary conditions, such as layered or functionally graded medium, multi-phase medium, composite materials, have aroused wide attention in recent years.
More detailed and accurate simulation on practical problems will undoubtedly advance better understanding on the wave motion nature. Finite element method (FEM) and Finite difference method (FDM) are two of the most popular mesh-based numerical approaches for wave motion analysis. However, numerical experiments suggest that 8-10 degrees of freedom (DOFs) per wavelength in each coordinate direction are needed for a good accuracy in the standard FEM and FDM. For high-frequency scattering problems, much finer meshing is required. The computational complexity grows quadratically with increasing wavelength/frequency or characteristic length. Therefore, the mesh reduction schemes need to be introduced to reduce the DOF requirement per wavelength in each coordinate direction. Examples of the mesh reduction methods include boundary element methods (BEM), method of fundamental solutions (MFS), Trefftz method, and Wave function expansion method. Papers addressing linear, nonlinear, direct and inverse wave propagation and scattering problems are welcome. The focus can be theoretical analysis of the mesh reduction method, as well as engineering applications.

The estimation problem of unmeasured states, unknown parameters or exogenous inputs for complex dynamics is a prerequisite for the implementation of a control strategy in practice. Emerging new fields of applications, such as biology, renewable energies, Internet of things, etc., necessitate reliable estimation algorithms for diverse classes of uncertain systems admitting new restrictions and requirements. Conventional approaches for estimation are based on the paradigm of asymptotic statistics and convergence, while in many areas the life horizon of a system is finite, and an action has to be performed on a finite interval of time as well. For instance, rapid case detection and response are key to ending a disease outbreak through efficient estimation of its parameter and subsequent decision making. Indeed, the efficacy of healthcare interventions is known to be higher during the burst stage of the epidemic episode. Another example: in a smart grid, after its commutation or a short circuit, the supervision system has only few seconds to take a decision about the new configuration, next guarding electronics may switch off the system for safety, which also requires fault detection and isolation tools working in finite time.

To ensure a non-asymptotic estimation (and control), many convergence concepts have been proposed: finite-time stability, fixed-time stability, hyper-exponential stability, stability in prescribed time. All these notions allow the design of control and estimation algorithms converging in a finite interval of time, then answering the requirements of new developing fields of application. To achieve convergence in finite or fixed-time, most approaches resort to high-gain injection, which calls for particular attention when deployed in noisy environments. Therefore, it is of primary importanceto characterize the robustness of this class of algorithms with respect to measurement noise, sensor delays and exogenous perturbations.

This special issue aims at presenting the last innovative results for design methods of finite-time estimation algorithms and their applications to fault detection and isolation or synchronization. An accompanying objective consists in the stimulation of a discussion on this subject and a comparison of existing finite-time and asymptotical approaches.

The special issue is devoted to all topics related to finitetime estimation and its applications, including (but not limited to) the following subjects:

- Finite/fixed-time (hyper-exponential or in prescribe time) algorithms for estimation of state, parameters or inputs;

- Parameter estimation of multi-sinusoidal signals and exponentially fading sinusoids;

- Benchmarking and comparison of finite-time and asymptotically estimating tools;

- Fault detection and isolation in a finite time Finite-time synchronization;

- Robustness analysis of non-asymptotic estimation algorithms;

- Discrete-time realizations of finite-time estimation algorithms;

- Tuning rules for convergence rate and robustness improvement;

- Applications for emerging and conventional areas of science and technology.

The importance of nonlinear impulsive systems (NISs) cannot be overemphasized. They are pervasive in many areas of science and engineering. Examples include neural networks, physics, secure communication, biological systems, financial markets, computer networks, signal processing systems, mechanics, automatic control, maneuvers of spacecraft, and electrical and mechanical structures. The most prominent feature of NISs is that they can take full account of the effects of instantaneous change and exhibit much complex dynamics. Generally, the study on NISs can be divided into two classes: impulsive perturbation (IP) and impulsive control (IC). In the case where a given system without impulse possesses certain performances such as periodic solution, attractor, stability, bifurcation, and boundedness, while the corresponding performance can be preserved when the system is subject to sudden perturbations. Such case is regarded as IP. While in the case where a given system without impulse does not possess a performance, but it can possess it via proper impulsive control, it is regarded as IC. No matter IP or IC, in past years, NISs have been studied in many areas of natural sciences, social sciences, engineering and mathematical sciences.

The purpose of this special issue is to provide a platform for researchers to disseminate original research in the fields of NISs. This is an excellent opportunity for researchers to report their recent progresses with the scientific community, in general and particularly working in the fields related to the title of the special issue. The researchers can contribute their original work that addresses any aspect of dynamics, control and modeling of NISs.

The list of possible topics includes, but is not limited to:

- Design of controllers for NISs

- Mathematical modeling for NISs

- Event-triggered IC of multi-agent systems or networked control systems

- Consensus and cooperative control of multi-agent systems subject to IP

- Stability and synchronization control of neural networks with IP or IC

- Delayed impulses, large-scale impulses, stochastic impulses, state impulse, hybrid impulse etc.

- Nonlinear stochastic systems with IP or IC

- Nonlinear time-delay systems with IP or IC

- Nonlinear hybrid systems with IP or IC

- Nonlinear fractional systems with IP or IC

This special issue is dedicated to the memory of Professor D.P. Rooke, who was a leading scientist in fracture mechanics. The handbook "Compendium of stress intensity factors" edited by D.P. Rooke and D.J. Cartwright was published in 1976. Both analytical solutions and numerical results of the stress intensity factors for cracked isotropic two-dimensional plate were collected. As the stress intensity factors are dependent of the configuration of the cracked body and loading conditions on the boundary, it is important to develop efficient and accurate numerical methods to deal with the complicated problems in practical engineering.

Although the finite element method is a matured tool to deal with a general problem in engineering, it is, however, not trivial to investigate the crack propagation and fatigue life with high accuracy. The mesh reduction methods, such as the dual boundary integral method, dislocation method, weight function method, displacement discontinuity method, etc., have their unique advantages for dealing with contact and moving boundary problems such as crack propagation. Recently, the meshless approaches including the local boundary integral equation method, the point collocation method with the radial basis function interpolation or the moving least square approximation, the method of fundamental solution, are getting more popular due to their high adaptive and simplicity in numerical implementation. Furthermore, for the fracture problems with anisotropic or functionally graded materials, the meshless methods present their unique advantages over other traditional methods.

This special issue is devoted to mesh reduction methods and their applications in fracture mechanics. Following methods are of specific interest:

1. Weight function method;

2. Dual boundary element method;

3. Dislocation method;

4. Displacement discontinuity method;

5. Boundary collocation method;

6. Semi-analytical method;

7. Meshless methods

Nervous tissue and heart muscle are important examples of biological excitable media. A key characteristic of an excitable medium is its capacity to allow the passage of electrical excitation from one element to another by means of local coupling. For neural and cardiac systems, this corresponds to their ability to respond strongly to the action of a relatively weak external stimulus delivered after the so-called refractory period (relatively weakbut strong enough to allow the membrane potential to cross the excitability threshold).

This special issue aims at providing an overview of recent theoretical and computational around neural and cardiac systems. The basic elements of both systems are excitable cells, neurons or cardiac myocytes respectively, which interact to form nervous tissue or heart muscle. The extensive use of mathematical and numerical techniques has allowed detailed studies to describe these two incredibly complex systems and to investigate underlying mechanisms. As both systems share important characteristics but have specific particularities, major objectives of this issue are, on the one hand, to show how both can be analyzed using similar techniques and, on the other hand, to showcase the dynamics of each particular system.

Specific topics of interest for this special issue focus on mathematical and numerical studies of the nonlinear dynamics of neuronal and cardiac systems, from isolated and coupled cells towards neuronal networks and cardiac tissue, using numerical modeling and time series analysis to elucidate the mechanisms underlying the onset, perpetuation, and control of complex neuronal and cardiac dynamics in health and disease.

Thus, the key objective of this special issue is twofold. First, to propose a snapshot of the current research landscape on these two remarkable examples of excitable media. Second, to emphasize the numerous links between studies on these two excitable scenarios by means of different theoretical (mathematical) and computational approaches. This undoubtedly lies within the scope of the Journal.

Asia has become home to many of the world's most dynamic markets, leading to unprecedented growth in manufacturing activities to meet the region's escalating demand for goods and services. Manufacturing in Asia is mainly carried out by small and medium manufacturing enterprises (SMMEs), which have helped accelerate the economic growth and development of the region. Sustainable economic development (SED) refers to development efforts aiming to make improvement in economic welfare that take social implications and environmental protection into consideration. So, SED seeks to improve the economic well-being and quality of life for a community by creating jobs, retraining/upgrading workers, and growing incomes and the tax base. With the deployment of advanced manufacturing technologies, and information and communications technologies, and increased innovation, the manufacturing sector in Asia has become increasingly more efficient, resilient, and responsive in its operations management. However, increased production activities also mean complex operations issues faced by these SMMEs, with consequences for the environment, resource sustainability, societal well-being, and overall quality of life. According to the Organization for Economic Cooperation and Developments (OECD) 2013 report, SMEs are the predominant form of enterprises, comprising approximately 99% of all firms. Furthermore, small-and-medium enterprises (SMEs) in the manufacturing sector account for a large part of the world's consumption of resources, air and water pollution, and generation of waste. Although the individual environmental footprints of small businesses may be small, the aggregate environmental damage they wreak in some sectors can exceed that of large companies. It is very crucial to get to grips with these phenomena to gain a better understanding of the economic, social, and environmental impacts of the operations of SMMEs in Asia.

SMEs are defined differently across countries, depending on the size of the domestic economy. For comparability across countries, we refer to OECD and define SMMEs as firms with a staff establishment of up to 249 persons with the following breakdown: micro (1 to 9), small (10 to 49), and medium (50-249). Indeed, Asian economies are at different stages of development and the roles played by Asia's SMMEs in contributing to SED may differ. We hope to document in this special issue (SI) the various perspectives and experiences of the SMMEs across Asia in addressing the operations management/production economics issues they face, and the lessons learned.

The purpose of this SI is to publish high-quality original research and review papers that address emerging operations management/production economics issues arising in SMMEs in Asia, and ascertain their roles in the SED of the continent. We invite original research works that employ quantitative and/or qualitative methodologies, such as empirical surveys, case studies, event studies, mathematical modeling, optimization, and simulation. This SI will adhere toIJPE's standard of publishing cutting-edge, relevant, and rigorous scholarship in plugging the existing research gaps. As such, we welcome novel submissions that are neither published nor currently under review elsewhere. Potential topics include, but are not limited to, the following:

- Challenges to operations management in SMMEs in Asia

- Data management and analysis in SMMEs in Asia

- Determinants of facility location by SMMEs in Asia

- Environmental quality and resource sustainability management in SMMEs in Asia

- Green sourcing, green logistics, and green manufacturing by SMMEs in Asia

- Human resources management and productivity in SMMEs in Asia

- Innovation strategies and outcomes in SMMEs in Asia

- Logistics and supply chain management in SMMEs in Asia
