Abstract

Lebenskunst hat Konjunktur: Offenbar ist der Traum, das Leben als Gesamtkunstwerk einzurichten, zur ethischen Maxime geworden. Beteiligt ist dabei seit der Antike das Motiv von Selbsterforschung bzw. Selbstbesserung, das über die Frühe Neuzeit bis in die Gegenwart wirksam geblieben ist. Tagebücher sind dabei ein notwendiges Begleitmedium gewesen und haben wechselhafte Formen angenommen, die von religiösen, wirtschaftlichen, psychologischen und medizinischen Aufschreibesystemen bestimmt worden sind. In diesem umfassenden mediologischen Sinn untersucht der Autor Programme der Selbstschrift und stellt diese an Beispielen dar, die sich von Pacioli über Pepys, Leibniz, Herder, Moritz, Goethe, Hebbel, Schmitt, Jünger oder Rainald Goetz bis in die Gegenwart der Social Media erstrecken.

Abstract

Value chains of bio-based chemicals are very complex. Hence, a strategic decision support tool for bioeconomic site and logistics planning is developed. It includes an integrated model and three sub-models: optimization for the locations and capacities of pretreatment plants, technical for technical and economic evaluations, risk for the evaluation of uncertainties. As a result, the model suggests a nearly optimal location and the associated logistic network for the production of biochemicals.

Abstract

This book is intended to gather recent studies on particle swarm optimization (PSO). In this book, readers can find the recent theoretical developments and applications on PSO algorithm. From the theoretical aspect, PSO has preserved its popularity because of the fast convergence rate, and a lot of hybrid algorithms have recently been developed in order to increase the performance of the algorithm. At the same time, PSO has also been used to solve different kinds of engineering optimization problems. In this book, a reader can find engineering applications of PSO, such as environmental economic dispatch and grid computing.

Abstract

Scheduling and control are typically viewed as separate applications because of historical factors such as limited computing resources. Now that algorithms and computing resources have advanced, there are new efforts to have short-term decisions (control) interact or merge with longer-term decisions (scheduling). A new generation of numerical optimization methods are evolving to capture additional benefits and unify the approach to manufacturing process automation. This special issue is a collection of some of the latest advancements in scheduling and control for both batch and continuous processes. It contains developments with multi-scale problem formulation, software for the new class of problems, and a survey of the strengths and weaknesses of successive levels of integration.

Abstract

This book contains the successful invited submissions to a Special Issue of Symmetry in the subject area of “Fuzzy Techniques for Decision Making”. We invited contributions addressing novel techniques and tools for decision making (e.g., group or multi-criteria decision making) with notions that overcome the problem of finding the membership degree of each element as in Zadeh's original model. We could garner interesting articles on a variety of setups as well as applications. As a result, this book includes some novel techniques and tools for decision making, such as instrumental tools for analysis (correlation coefficients, similarity measures, aggregation operators) in various settings and novel methodological contributions (discrete optimization with fuzzy constraints, COMET, or fuzzy bi-matrix games) and applications (to project delivery systems, maintenance performance in industry, group emergencies, pedestrians flows, valuation of assets, water pollution control, or aquaculture enterprise sustainability). The published submissions cover models like fuzzy soft sets, hesitant fuzzy sets, (fuzzy) soft rough sets, neutrosophic sets, as well as other hybrid models.

Abstract

Micro-total analysis systems and lab-on-a-chip platforms are widely used for sample preparation and analysis, drug delivery, and biological and chemical syntheses. A micromixer is an important component in these applications. Rapid and efficient mixing is a challenging task in the design and development of micromixers. The flow in micromixers is laminar, and, thus, the mixing is primarily dominated by diffusion. Recently, diverse techniques have been developed to promote mixing by enlarging the interfacial area between the fluids or by increasing the residential time of fluids in the micromixer. Based on their mixing mechanism, micromixers are classified into two types: active and passive. Passive micromixers are easy to fabricate and generally use geometry modification to cause chaotic advection or lamination to promote the mixing of the fluid samples, unlike active micromixers, which use moving parts or some external agitation/energy for the mixing. Many researchers have studied various geometries to design efficient passive micromixers. Recently, numerical optimization techniques based on computational fluid dynamic analysis have been proven to be efficient tools in the design of micromixers. The current Special Issue covers new mechanisms, design, numerical and/or experimental mixing analysis, and design optimization of various passive micromixers.

Abstract

In order to establish general principles in the topic of motion planning for fully-automated driving, an intuitive problem statement in the form of an Euler–Lagrange Model is derived and transformed into a corresponding Hidden Markov Model for global optimization. Geometric and topologic considerations lead to a probabilistic environment modelling in combination with the C² model and result in general conclusions about the structure of traffic situations.

Abstract

The desired properties of surface components include the improvement of different properties, such as aesthetic appearance, oxidation resistance, wear resistance, mechanical properties, electronic or electrical properties, thermal insulation, wear, triboemission and corrosion resistance through barriers.These properties can be enhanced using different methods, such as by adding a coating. Nevertheless, the bulk of the material or substrate cannot be considered independent of the surface treatment. Metal cutting is one of the general machining methods used to achieve high accuracy and productivity for metal parts.The topics of the book “Manufacturing and Surface Engineering” include the full range of surface engineering aspects, i.e., surface integrity, contact mechanics, friction and wear, coatings and surface treatments, multiscale tribology, computational methods, and optimization techniques applied in surface engineering.Recent experimental works by Zhang, Li, Zhang, Zhang and Duan, and by other researchers outlined that coating layer surface treatments may increase the damping behavior of thin-walled mechanical components vibrating in flexural conditions. Nevertheless, it was also experimentally found by the authors that most of these coating surface treatments had a negligible or null effect with respect to the vibrational damped response in testing or operating conditions. Ciniero, Le Rouzic and Reddyhoff report the potential of measuring charged particle emissions and/or tribocharging for the study or monitoring of the failure of coatings. The spatial information of triboemission allows the identification of the exact time and location of the failure. The evolution of the failure during sliding and the change in the characteristics of the contact are also monitored. After studying the effect of the Ti content on the performance of FeCoCrNiAlTix, He, Zhang, Lin, Zhang, Dong and Li establish that the structure of FeCoCrNiAlTix coatings consists of two kinds of BCC phases. With the continuous increase in Ti content, the number of eutectic structures decreases, accompanying the increase in the proeutectic phase and the Ti-rich second phase is precipitated out. Abutaha, Abdul Razak, and Ibrahim developed an experimental investigation into the engineering properties of concrete incorporating POC as an aggregate and filler material. This approach offers an environmentally-friendly solution to the ongoing waste problems associated with palm oil waste material.Liu and Janssen studied the effects of impact on the wear of the structural steel S235 in various liquids. When the impact is small, corrosion plays a dominant role, thus the sample in seawater wears the least due to the beneficial interaction with abrasion. However, when the impact is large, the wear rates of three liquids do not show a noticeable difference, because the wear mechanism changes from material removal to mainly plastic deformation. The influence of corrosion becomes a minor influencing factor when subject to impact.Vázquez Martínez, Salguero Gómez, Batista Ponce and Botana Pedemonte analyzed the different treatments obtained through setup parameter combinations to obtain samples with widely varying features, according to the thickness of the treated layer and the incidence depth of the laser beam. This diversity of samples shows a range of color tonalities from soft gold to medium gray and blue. Microstructural changes and oxidation layer generation provide a significant increase in the material hardness, reaching Vickers hardness values close to 1000 HV for high intensity treatments.Takada and Sasahara studied the FSB process using four levels of tip radius burnishing tools and investigated their effect on surface roughness, hardness and residual stress for a 0.45% C steel shaft. The thickness of the hardened layer increased as the tool tip radius decreased. The hardness value of the processed layer reached 600 HV. The residual stress on the processed surface was compressive when a radius tool with a smaller tip was used, and the residual stress turned tensile when a radius tool with a larger tip was used.Vereschaka, Kataeva, Sitnikov, Aksenenko, Oganyan and Sotova searched for patterns that allow a reliable justification for the choice of the composition of coatings and their micro- and nanostructures depending on the material being machined and the cutting regimes (in particular, the cutting speed).Amadori, Catania and Casagrande investigated experimentally eight different innovative composite solutions. A significant increase in the damping behavior was observed for all of these solutions with respect to the uncoated components, and with respect to the already known solutions that have previously been investigated by these authors and other researchers. The coating solution employing an Al2O3 powder + matrix, made using a screen-printing and curing technology on an Al alloy substrate, proved to be the most effective technology with respect to the aim of this work. Catania and Strozzi investigated the performance of different solutions in a free and forced flexural vibration response; they propose a simple model based on the assumption of a multi-layer, zig-zag beam, which also locally models the dissipative actions at the interface between the layers. Some virtual prototyping application examples are also reported.

Abstract

Neutrosophic logic and set are gaining significant attention in solving many real-life problems that involve uncertainty, impreciseness, vagueness, incompleteness, inconsistency, and indeterminacy. A number of new neutrosophic theories have been proposed and have been applied in Multi-Criteria Decision-Making, computational intelligence, multiple-attribute decision-making, image processing, medical diagnosis, fault diagnosis, optimization design, and so on. Neutrosophic logic, set, probability, statistics, etc., are, respectively, generalizations of fuzzy and intuitionistic fuzzy logic and set, classical and imprecise probability, classical statistics and so on.This Special Issue gathers 11 original research papers that report on the state of the art and recent advancements in Multi-Criteria Decision-Making using neutrosophic environment in computing, artificial intelligence, big and small data mining, group decision-making problems, pattern recognition, information processing, image processing, and many other practical achievements.
