Optimization of Air Handler Controllers for Comfort Level in Smart Buildings Using Nature Inspired Algorithm

This research seeks to improve the temperature control of AHU in building sub-levels using optimization algorithms. Specifically, the study applies the FA and PSO algorithms to optimize the PID control of AHU’s temperature. The study addresses the issue of temperature control in building sub-levels, which is a common challenge in HVAC systems. The study uses optimization algorithms and a nonlinear model to improve temperature control and reduce fluctuations in temperature from the desired setting. Additionally, a NL-ARX algorithm is utilized to create a nonlinear model based on the thermal dynamics and energy behavioral patterns of ACMV cooling systems. The study evaluates the performance of three controllers—PID, FA-PID, and PSO-PID—based on ITSE as a performance index. The study compares the performance of these controllers to achieve the desired temperature setting, and it analyses the influence of temperature regulation on occupant comfort levels. In this study, we compare different controllers using ITSE as a performance indicator. This shows how well different optimization algorithms work at setting the right temperature. The research gap is the lack of efficient temperature control solutions in building sub-levels that can optimize occupant comfort and energy efficiency. The experimental findings confirm that PSO-PID outperforms conventional PID and FA-PID optimization in terms of achieving the goal objective via computational complexity. Overall, this study’s focus is to explore and compare different optimization algorithms to improve temperature control and occupant comfort in building sub-levels.

Hybridized artificial intelligence models with nature-inspired algorithms for river flow modeling: A comprehensive review, assessment, and possible future research directions

River flow (Qflow) is a hydrological process that considerably impacts the management and sustainability of water resources. The literature has shown great potential for nature-inspired optimized algorithms (NIOAs), like hybrid artificial intelligence (HAI) models, for Qflow modeling. Qflow forecasting needs to be accurate, robust, reliable, and capable of resolving complex non-linear problems to support the decision authority in local and national governments and NGOs. This extensive survey provides a literature review of 100-plus high-impact factor journal articles on developing NIOAs models during 2000–2022. This encompasses a comprehensive review of the established research in different climatic zones, NIOA types, artificial intelligence (AI) models, the input parameters used for model development, Qflow on different time scales, and model evaluation using a wide range of performance metrics. The review also assessed and evaluated several components of relevant literature, along with detailing the existing research gaps. Moreover, the global research gap with future direction is discussed based on current research limitations and possibilities. The data availability evaluation and futuristic suggestions are drafted logically. The review revealed the superiority of the NIOAs among all applied algorithms in the literature. Further, the review concludes that there is a need to improve technical aspects of Qflow forecasting and bridge the gap between scientific research, hydrometeorological model development, and real-world flood and drought management using probabilistic nature inspired (NI) forecasts, especially through effective communication.

Photothermal‐Driven Crawlable Soft Robot with Bionic Earthworm‐Like Bristle Structure

Remote stimuli‐responsive movable soft robots without the need for complex 3D deformation processes and specific working environments is an unsolved problem and urgent need. In this work, under the inspiration of mother nature, a novel strategy of simple combination of the bionic bristles structure and the photothermal‐driven reversible shape change liquid crystal polymer (LCP) actuator is proposed to work out this difficulty. The combination structure is designed as unique three parts with two bionic bristle units at the two ends and one LCP unit in the center with a soft connection between them. After matching the driving force and the resistance, the prepared soft robot can realize the earthworm‐like unidirectionally crawl on the paper surface upon near‐infrared light irradiation through the contracting and stretching of LCP with a maximum average speed of 4.4 mm min−1. What's more, the crawling speed of the soft robot can be regulated by varying the irradiation distance of near‐infrared light or the length of the actuators. This strategy realizes the type of remote wireless control soft robot and has potential application ability in other soft robots with various demands.

Biomimicry Architecture for Healthy Built Environment: A Review of Existing Literature

Health issues in the 21st century have become essential in addition to sustainable development issues. Health is an urgent need to find solutions to problems so that human health is always maintained. Health issues are also influenced by the built environment, one of which is studied in the concept of healthy building. A healthy building has several criteria that can be a point of view to see if the building is healthy or unhealthy. Physiological, psychological and disease transmission problems are the main problems faced by users who use unhealthy buildings. Biomimicry architecture emerged due to technological and scientific advances, in which cross-disciplinary science has become the power of knowledge today. Biomimicry architecture is a design approach that uses nature to solve human problems. Health problems and the need to produce healthy buildings can use biomimicry architecture as a problem-solving method. This paper uses a descriptive qualitative content analysis method on various written references related to biomimicry architecture and how biomimicry architecture produces healthy buildings. The conclusion of this study shows that biomimicry architecture is an approach to using natural inspiration to solve human problems, one of which is building health. Implementing principles found in nature delivers buildings designed with a biomimicry architectural approach to be healthier. That is due to the successful application of natural traits that are always adaptive, efficient, effective and live in line with the environment in the built environment.

A Nature Inspired Hybrid Partitional Clustering Method Based on Grey Wolf Optimization and JAYA Algorithm

This paper presents a hybrid meta-heuristic algorithm using Grey Wolf optimization (GWO) and JAYA algorithm for data clustering. The idea is use exploitative capability of JAYA algorithm in the explorative phase of GWO to form compact clusters. Here, instead of using one best and one worst solution for generating offspring, three best wolfs and three worst omega wolfs of the population are used. So, the best wolfs and worst omega wolfs assist in moving the new solutions towards the best solutions and simultaneously helps in staying away from the worst solutions. This enhances the chances of reaching the near optimal solutions. The superiority of the proposed method is compared with five promising algorithms, namely GWO, Sine-Cosine Algorithm (SCA), Particle Swarm Optimization (PSO), JAYA and K-means algorithms. The result obtained from the Duncan’s multiple range test and Nemenyi hypothesis based statistical test confirms the superiority and robustness of our proposed method.

Natural deep eutectic solvents (NaDES) as an emerging technology for the valorisation of natural products and agro‐food residues: a review

SummaryA review paper on the natural deep eutectic solvents (NaDES) application to the extraction of bioactives from natural products and agri‐food wastes is introduced. NaDES are eutectic mixtures of two or more natural compounds forming a liquid phase at room temperature based in hydrogen bond acceptors (quaternary amines, alcohols) and hydrogen bond donors (sugars, organic acids). NADES have unique properties such as low toxicity, biodegradability and high solubility for a wide range of compounds. They represent a sustainable alternative to traditional organic solvents in a variety of applications, particularly metabolites extraction. Therefore, the status of NaDES is displayed in terms of their inspiration in nature, their preparation and physicochemical properties, as well as the extraction conditions for biologically important phytochemicals such as alkaloids, carotenoids, and phenolics (anthocyanins, isoflavonoids, and curcuminoids). Remarks on emerging technologies as well on therapeutic, hydrophilic, and hydrophobic NaDES systems are inserted. As NaDES can be easily prepared from natural and renewable sources, they are a promising green alternative in the food, nutraceutical, and pharmaceutical industries.

“A Songwriter’s Avalanche”: Nature and Creativity in Jason Ringenberg’s Stand Tall

Musicians have always sought inspiration in nature. The music they compose may represent nature in different ways. What is less known, however, is how this creative process unfolds. Through one case study—Americana artist Jason Ringenberg’s album Stand Tall—I explore how an encounter with the natural environment resulted in a burst of creative activity. Specifically, Ringenberg was commissioned by the U.S. National Park Service to write songs as an artist-in-residence in Sequoia National Park, California. Primarily based on an in-depth interview with Ringenberg, I show how creativity in nature takes many shapes. Specific sites and the circumstances in which Ringenberg encountered nature matter, as do experiences of solitude and closeness to nature through hikes and primitive living arrangements. The history and nature of the park—particularly its namesake trees and environmentalist John Muir—inspired the writing of songs that were directly representational of that environment. At other times creativity was opaque, even to the composer himself, in that songs were not thematically connected to the setting. Moreover, Ringenberg sensed a spiritual connection with nature which, filtered through his own beliefs and experiences, informed his personal artistic expressions.

Modulation of Biophysical Cues in Nature Inspired Patterning of Porous Silk Fibroin Scaffold for Replenishable Controlled Drug Delivery.

In our daily lives, cuts and wounds are unavoidable. while they are generally minor, sometimes they do turn serious. While a sticking plaster might be enough in most cases, critical situations like surgical wounds, lacerations, gunshot wounds, accidental skin injuries, diabetic wounds, and other cutaneous deep cuts may require implants and simultaneous medications for healing. From the biophysical standpoint one of the least explored aspects to surmount these hurdles is the internal force-based physical surface stimulus crucial for cellular sensing at the time of wound repair. With more people needing medical attention for wound healing, smart patches will be an integral part of the future generation of wound treatment. We report fabrication of a novel biomimetically patterned silk fibroin porous scaffold with an approach to ampicillin loading and replenishment by joining a polytetrafluoroethylene (PTFE) catheter attached 18G butterfly intravenous infusion needle at the bottom of the substrates. In vitro swelling study reveals that the patterned substrates show less swelling compared to that of the other variants and consequently less in vitro degradation. The ampicillin release patterns from the scaffolds follows the Korsemeyer-Peppas model depicting surface hydrophobicity mediated non-fickian first-order anomalous controlled release. The scaffolds show remarkable antibacterial efficacy against Methicillin-Resistant Staphylococcus aureus (MRSA) and Escherichia coli. Four distinct cell-matrix adhesion regimes were investigated for the fibroblasts to eventually form cell sheets all over the hierarchical surface structures. The fluorescence images after DAPI and FDA staining clearly demonstrates that the patterned surface to be superior to its other variants. A comparative study among molecular expressions of collagen I, vinculin, and vimentin using immunofluorescence, substantiated the patterned surface to be superior to others. The work report potential development of a deep cutaneous wound healing drug replenishable implant with biophysical cues capable of controlling fibroblast behavior and release kinetics of ampicillin.

Design and implementation of adaptive network stabilization based on artificial bees colony optimization for nature inspired cyber security

Adaptive Defense has become an important factor in order to maintain device safety and security on the Internet. In 2021, there were more than 10 billion devices connected to the Internet which is estimated to exceed 25.4 billion by 2030. In order to implement the defensive mechanism approach to security, this paper demonstrates the implementation of the Artificial Bees Colonization (ABC) Approach as Nature Inspired Cyber Security Algorithm. This paper analyzes the defensive approach to Distributed Denial-of-Service attack which limits the amount of traffic flow from each node, therefore, minimizing the attack surface. The simulated network shows the difference between the normal and attack throughput and compares the fitness of the network intermediaries with reference to the parametric graph that shows the effect of a simulated attack on each network intermediary. Thereafter, the state of defense from the ABC’s point of view shows the effectiveness of the proposed algorithm in detecting and minimizing traffic flow from malicious nodes thus, maintaining the network throughput while keeping the network stable.The proposed algorithm introduces an Adaptive Defense Approach that works recursively on the nodes attached to a network of clusters that prepares a solution set of probable malicious nodes that are attached to the network. The detected nodes are then analyzed by their properties based on the network parameters such as Network Throughput, End-to-End Delay, and Packet Delivery Ratio. On change in any of the factors in the devised properties, the node or cluster of nodes is marked as malicious and the rate of traffic flow along with the packet delivery ratio is reduced to match the normal node’s generic properties such that the hammering of the network with traffic is done under a controlled environment and the network works with reduced performance but does not halt even under attack thereby, maintaining business continuity under attack scenario.

Sub-Focus Analysis of Naturalist Intelligence In Early Children

The world of early childhood plays, and when children play in nature, it is actually a very valuable practice for children to facilitate their growing bond with nature. Early childhood is a sensitive period that can be a source of inspiration when children play in nature. Learning about nature is part of naturalist intelligence which can generate inspiration and children's exploration of nature. This qualitative research aims to explore the sub-focus of recognizing, differentiating, and classifying as well as expressing naturalist intelligence in early childhood. The participants involved in this study were two people consisting of one teacher and one PAUD head in a city in Indonesia. Interviews and documentation formed the basis of the research method, and data were analyzed using taxonomic analysis, with the results showing that all the children studied had a sub-focus on recognizing, differentiating, and classifying, as well as expressing about plants, animals, and natural objects around them (naturalist intelligence). However, this article only discusses the sub-focus on getting to know plants, animals, and natural objects around children. This research reveals that naturalist intelligence in early childhood can be developed through school support

Wordsworth's View of Nature: Return to nature and Find Psychological Well-being

In modern society, people are suffering from more and more stress, which leads to various mental diseases. However, William Wordsworth, as a famous British romantic poet in the 19th century, had his own methods to release pressure and maintain mental health. His nature poetry is fresh and moving, delicate and beautiful, describing all kinds of beautiful natural scenery. By eulogizing the beauty of nature, we can feel the inspiration of nature to human beings, and express the poet's symbiosis with nature and his love for nature. This paper will mainly analyze the view of nature in Wordsworth's famous work “I Wandered Lonely As a Cloud”, and explore the practical methods to find psychological well-being for modern people.

The Fractal Approach in the Biomimetic Urban Design: Le Corbusier and Patrick Schumacher

Biomimetic design process approaches have been emphasized systematically as a result of works among disciplines of current technology and biological science. In order to find solutions for a decrease in biodiversity, pollution, and issues of the ecosystem, the nature experience shows itself in areas of biomimetic products, architecture, and urban designs in which nature-focused invasions are basically being imitated. Nature-focused designs have set their own framework by examining forms of different nature dynamics (scale, function, formation process) by presenting a sustainable environment. It can be seen that designs are made real by adhering to the resolution of forms, understanding, and interpretation of nature and by embracing fractal designs with the effort of creating a sustainable environment. In this study, emphasis was placed on revealed nature-based design approaches. The article addresses biomimetic design processes, reveals the role of fractal parameters in the design process, and examines the use of biomimetic approaches. By drawing attention to the importance of studying and understanding these internal dynamics, the contribution of natural inspiration and fractal concepts to the design process is examined. We examine research related to the concept of biomimetics, creation/development of conceptual proposals, and analysis of the established theoretical proposal through selected urban design examples in order to determine the respective overlaps between these areas. Our study takes the form of an analysis of the formal organization of living things together with a formal analysis focusing on the design principles. We try to analyze the design principles and the changes in the principles, and discuss the resulting data within the framework of these concepts. The urban designs of Le Corbusier and Patrick Schumacher, who are important names of the 20th century, were examined in line with the findings obtained in terms of biomimesis levels, namely, the organism level, behavior level, ecosystem level, and functional level. Comparisons of urban design approaches are made using the meta-analysis method with respect to findings obtained as a result of an examination of the golden ratio, modular system, fractal, and parameter concepts of urban design. For this reason, when the fractal concept, which is one of the dynamics of biomimetic-oriented nature, is handled with biomimetic levels and its contribution to the design processes is investigated, we are able to determine that it has important parameters in terms of sustainability. This study aims to contribute to the field of industrial products and urban design disciplines in architectural design.

Aquaporin‐Based Biomimetic Membranes for Low Energy Water Desalination and Separation Applications

AbstractThe emergence of biomimetic materials developed using nature's inspiration and biological domains can drive a paradigm shift in the design and operation of future‐generation materials in separation applications. In recent years, biomimetic membranes have drawn interest of many researchers for water treatment applications. Among the biomimetic membranes, protein‐based membranes, specifically those synthesized by aquaporin, have received much attention in recent years due to their high osmotic water permeability and excellent ability to remove small molecules, thereby overcoming the trade‐off between the water flux and the contaminant's rejection. The separation efficiency and fouling properties are significantly improved by taking advantage of the strategies evolved in nature. This review provides a comprehensive overview of the state‐of‐the‐art aquaporin‐based biomimetic membranes (ABMs), mainly focusing on their synthesis, characterization, and performance as selective layer in composite membranes for reverse osmosis, nanofiltration, and forward osmosis for water desalination. Fabrication methods and characterization techniques of ABMs and their performance in water desalination are also reviewed, while the main obstacles for their successful commercial viability in wastewater treatment are provided. The applications of ABMs in various separation processes other than water desalination and their potential market are presented to inspire future researchers in this versatile area.

Nature Inspired Manganese(III)-Calcium Complexes: Towards Synthetic Models for the WOC of PSII

For some time, the presence of high oxidation state Mn ions and Ca(II) in the active center of Photosystem II has been known. However, coordination complexes that combine both Mn(III) and Ca(II) have been difficult to obtain, with only a handful of examples reported. In this paper we report the synthesis of two new Mn(III)-Ca(II) complexes, 1 [Pr2NH2]3[Mn6CaO2(OH)(OMe)3(SALO)6 (SALOH)3] and 2 [Mn18Ca6O12(OH)6(MeO)12(PhCOO)18(MeOH)6]. The complexes have been characterized by single-crystal X-ray diffraction to establish the oxidation state of manganese. The use of salicylato ligands with tert-butyl substituents leads to effective encapsulation of a Ca(II) ion in a cavity that has both hydrophobic and hydrophilic regions, mimicking the enzyme environment.
