The study investigates the departure counting process in a finite-buffer queueing system with batch arrivals and multiple vacation policy. A representation for the mixed double transform of the number of departures up to the fixed time moment is obtained in the explicit form applying analytic approach based on integral equations and linear algebra. Numerical study is attached that focuses on understanding the impact of various system parameters on the behaviour of the mean number of packets processed within a fixed time frame. Utilizing numerical experiments, the study examines the influence of vacation duration, initial buffer state, arrival intensity, and processing rate on the departure process. Results reveal significant dependencies between these parameters and the transient behaviour of the queueing system. Notably, the service speed parameter demonstrates the most substantial influence on the mean number of processed packets, followed by the arrival rate. Conversely, variations in vacation duration and initial packet count exhibit comparatively minor effects on system behaviour. Overall, the findings provide valuable insights into the dynamics of departure processes in finite-buffer queue systems with batch arrivals and multiple vacation policies, offering implications for system optimization and performance enhancement strategies. © 2024, The Authors.

This paper presents a concept for an integrated process chain for tooling production based on metal additive manufacturing. The proposed approach aims at taking advantage of a fully digitized production line, describing the main steps for the synergetic integration of the manufacturing assets. The production line entails digital infrastructure that collects and elaborate data from various monitoring sensors to execute corrective actions and continuously optimize the process. This line will bring breakthrough benefits, like flexibility and full traceability. Also challenges, as change management in the industry, skills gap, the requirement of new business models and product re-design have been addressed. © 2020 The Authors.

We propose an effective and flexible way to assemble tangent stiffness matrices in MATLAB. Our technique is applied to elastoplastic problems formulated in terms of displacements and discretized by the finite element method. The tangent stiffness matrix is repeatedly assembled in each time step and in each iteration of the semismooth Newton method. We consider von Mises and Drucker-Prager yield criteria, linear and quadratic finite elements in two and three space dimensions. Our codes are vectorized and available for download. Comparisons with other available MATLAB codes show, that our technique is also efficient for purely elastic problems. In elastoplasticity, the assembly times are linearly proportional to the number of integration points.

A recent article ‘Burden of proof: A comprehensive review of the feasibility of 100% renewable-electricity systems’ claims that many studies of 100% renewable electricity systems do not demonstrate sufficient technical feasibility, according to the criteria of the article’s authors (henceforth ‘the authors’). Here we analyse the authors’ methodology and find it problematic. The feasibility criteria chosen by the authors are important, but are also easily addressed at low economic cost, while not affecting the main conclusions of the reviewed studies and certainly not affecting their technical feasibility. A more thorough review reveals that all of the issues have already been addressed in the engineering and modelling literature. Nuclear power, which the authors have evaluated positively elsewhere, faces other, genuine feasibility problems, such as the finiteness of uranium resources and a reliance on unproven technologies in the medium- to long-term. Energy systems based on renewables, on the other hand, are not only feasible, but already economically viable and decreasing in cost every year. Copyright © 2017, The Authors. All rights reserved.

We study a new mode of the neutrinoless and two-neutrino double-beta decays in which one of the electrons is emitted from the atom, while the other is directly produced in one of the available s1/2 or p1/2 subshells of the daughter ion. We calculate the phase-space factors, estimate the half-lives and derive the single-electron spectra for 0+ → 0+ ground-state nuclear transitions of the most relevant double-beta-decay isotopes: 48Ca, 76Ge, 82Se, 100Mo, 136Xe and 150Nd. The relativistic electron wave functions are evaluated at the nuclear radius by means of the multiconfiguration Dirac–Hartree–Fock package Grasp2K. We discuss the prospects for detecting these new modes in the tracking-and-calorimetry experiments NEMO-3 and SuperNEMO.

The sustainability of aquaculture industry strongly dependence on numerous factors such as environmental, ecology, economics, industry, human behaviour, policy and many other factors. The interdependence of this factors is called as eco-aquaculture. However, eco-aquaculture field has not been widely studied, especially in Malaysia. Therefore, to fundamentally enhance the sustainable development capacity of an eco-aquaculture system, the integrated simulation and analysis of the material-energy flow processes and the trends of process generates the ecological and economic positive-negative effects should be addressed. Thus, we build a system dynamics model of the eco-aquaculture system named “SD-AQEP” to simulate quantitatively material and energy flow in the local eco-aquaculture industry chain, evaluate and analyse the integrated effects of the ecological-economy and their long-term evolution trends, identify the defects of the system and then make recommendations to improve system performance until 2025. This model is divide into three parts: aquaculture, policy and effects and also the interaction and material-energy flow mechanism among each part as the logical framework of modeling. In this study, we focus on the eco-aquaculture system particularly at Integrated Aquaculture Park (i-Sharp), Setiu, Terengganu; Malaysia. The results from the simulation revealed that the potential risks which are the negative effects of the system are identified. Then, the system improvement especially policies are made in order to reduce, eliminate all the risks as well as negative effects and at the same time bring and expand the ecological and economic to the positive effects. The systems also can diagnose scientifically the potential short-comings and defects in the system, provided the basic improvement policies as well as checking the effectiveness of the improvement policies. Hence, this system is potential to revealing the internal structures in the complex system with ecos
