Green Polymorphic Cooperative Formation Strategy of Low-Carbon Unmanned Surface Vessels

At the current stage of a global energy shortage, the optimization of marine energy consumption has received attention. In order to save marine energy consumption and reduce pollution, research on low-energy-consumption Unmanned Surface Vessels (USVs) and their green and low-carbon cooperative operation methods needs to be paid attention to. Due to the ever-changing environment of USVs in actual sea conditions and the increasingly complex tasks, the cooperation of a single swarm of USVs is incompetent. First, in order to cope with larger-scale and complex tasks, we construct the multilateral cooperative control system for USVs with topology scalability under a polymorphic network and propose the multilateral distributed control protocol. Second, in order to reduce the energy consumption of the cooperative operation of USVs, the low-energy-consumption and low-carbon USVs are selected with the lowest EEOI index as the optimization goal, and based on ad hoc on-demand distance vector routing (AODV), the optimal path between USVs is obtained. Then, the swarms are grouped by External Equitable Partition (EEP), and the green autonomous cooperative formation strategy is proposed. Finally, the simulation examples are used to verify the effectiveness of the method proposed in this article.

Decisions and Coordination of Green Supply Chain Considering Big Data Targeted Advertising

The application of big data targeted advertising in the green supply chain makes the green marketing of products more accurate and effective. This paper applies game theory to study the decisions and coordination issues of a green supply chain in which the online retailer conducts big data targeted advertising. A centralized model and two Stackelberg game models (an online-retailer-led decentralized model and a manufacturer-led decentralized model) were constructed and solved. The zero wholesale price-side-payment contract and greedy wholesale price-side-payment contract were introduced into the green supply chain for coordination. The study found that: (1) the increase in demand attenuation coefficient, green sensitivity coefficient, and big data targeted advertising sensitivity coefficient will be beneficial to the growth of total consumer demand, supply chain profit, and environmental benefit; (2) supply chain coordination is necessary because greenness, demand, supply chain profit, and environmental benefit under the centralized model are higher than those under two decentralized models; (3) two contracts can achieve the coordination of the green supply chain, and the profits of the manufacturer and online retailer under the contract are greater than those under the decentralized model. The results can provide insights for promoting green supply chain operations.

Assessing Green Supply Chain OperationReference with Life Cycle Inventory: The Case ofGamboeng Green Tea, Indonesia

This study aims to assess the performance of the Gamboeng green tea production system using the Green Supply Chain Operation Reference (GreenSCOR). Fifteen environmental performance indicators were incorporated in the five main processes in the supply chain: planning, sourcing, production, delivery and return. The data were collected from field observations of the supply chain structure and flow process inventory, then validated through in-depth interview with key informants. Data inventory of processes was utilized for measuring several indicators especially in the planning process and the realization of the plan in the production process. Gamboeng tea has an advantage score in indicator of realization (15%) for use of clean energy source (i.e., wood pellet) to substitute liquified petroleum gas as well as for using environmentally friendly packaging, zero waste disposal and total recyclable waste. Further improvements are recommended for the five performance indicators, particularly in the planning process, such as providing training and education for personnel about environmental awareness and management, planning for minimizing water usage, planning in minimizing inorganic fertilizer usage, screening suppliers, and using larger portions of wood pellets.

Strategic investment for green product development and green marketing in a supply chain

Growing environmental awareness among consumers and corporate environmental responsibility prompt enterprises to pay more attention to green operations. Green practices, such as green product development (GPD) and green marketing strategies, affect the sustainability of a supply chain. This paper considers four scenarios to determine who is more suitable to implement GPD or green marketing in a supply chain consisting of a manufacturer and a retailer regarding products with green attributes. Several findings are derived. First, there is a significant interaction between GPD and green marketing decisions. These two important decisions should be considered simultaneously in a supply chain. Second, when the green marketing cost factor is sufficiently high, the manufacturer, retailer, whole supply chain, environment, and consumers will benefit from the scenario where the manufacturer leads in both GPD and green marketing, which may explain the common practice of the manufacturer conducting both GPD and green marketing. From the retailer's perspective, adopting both GPD and green marketing is always a bad choice. The environmental impact and consumer surplus are also investigated. For improving the environment and enhancing consumer surplus, it is best to enhance consumers' awareness of a product's green degree and enable the consumers to derive more positive utility from green marketing.

Research on Internal Parameter Filtering of Natural Gas Pipeline under Duty Cycle Transmission Mechanism

In recent years, with the continuous growth of China's long-distance oil and gas pipeline network, wireless communication network applications have become more and more extensive with the continuous promotion of intelligent oilfield construction, while the energy-saving problem in the process of information transmission has become increasingly prominent. In order to ensure the sustainable development of China's oil and gas industry, low-power wireless transmission has become a basic requirement for the current intelligent oil and gas pipeline communication construction. For the monitoring of pipeline operating conditions, pressure and flow rate values are important parameters. If the accuracy and comprehensiveness of pipeline operation data can be ensured simultaneously under an energy-efficient transmission mechanism, it will provide strong support for the green and safe operation of pipelines. Therefore, in this paper, a recursive filtering study is conducted for natural gas gathering pipeline flow system under duty cycle transmission mechanism to complete the reliable monitoring of pipeline fluid transportation status.

Enhancing the Green Climate Fund operations through a climate justice lens

The prevailing issues in the Green Climate Fund on implementation and governance can be seen as symptoms of the ills of the international climate finance architecture. These are compounded by the inadequate financial support provided by developed countries to developing countries and the low volume of funding channelled to adaptation projects. Evidently, the cited issues highlight the need to fully integrate the principles of justice and equity into the global climate change regime. Thus, this policy brief discusses the key challenges related to climate finance, and outlines several options and considerations on improving the Green Climate Fund operations using a climate justice lens. This paper intends to take a more normative and ethical discussion on the topic of climate finance.

Milk provides the basis for an eco-friendly shorter process for skin preservation and leather manufacture

The traditional beamhouse method for tanning skins to produce leather uses copious amounts of water, large quantities of chemicals deemed to be dangerous by the public and produces large quantities of liquid waste (90 kg/ton of raw hide) that have become a significant problem due to environmental concerns. In this work, we chart the development of the use of a milk product that both preserves unwashed sheepskins and depilates them, removing the need for salt, sulfide and lime and reduces the copious amounts of water used in the traditional process. This method can completely replace salting and the first five steps of the traditional beamhouse process and the depilated skins can be taken straight to degreasing and tanning. Evaluation of the depilated skins by both eye and high-resolution microscopy showed no apparent damage to the grain or fraying of the collagen bundles. The leather produced from them had physical properties that were either identical or better than those of leather made using the traditional methods. To try and understand the process, microbial culturing of the depilation liquid routinely identified two major bacterial species ( Lactococcus lactis and Lactiplantibacillus plantarum ) and two major fungal species ( Geotrichum candidum and Yarrowia lipolytica ) among other minor species. We predict that the secretion of an unidentified mix of antimicrobial substances and extracellular enzymes from these microorganisms are responsible for the preservation and depilation of sheepskin. This procedure shows potential for further development and could result in a sustainable green beamhouse operation for the leather industry. • A completely sulfide free protocol for sheepskin depilation has been developed. • It uses dairy by-products whey or permeate to preserve and depilate over 3–4 days. • No need to lime, delime bate or pickle so water use is considerably reduced. • The resulting leather has an enhanced appearance compared to normal leather. • The leather's physical properties are the same as those of the traditional product.

Constant and Green Mode Operation Technique in Flyback and Push-Pull DC-DC Converter

Abstract: The high frequency switching causes switching losses and reduces the efficiency of converters. Therefore, operating the DC-DC converters with lower frequencies at light loads reduces the switching losses significantly. Variable frequency switching is generally defined as Green mode operation. The green mode control method is obtained from high efficiency over the entire load range. This method is also called variable frequency control and it changes the switching frequency according to the load condition. At full load conditions, the controller increases the switching frequency to decrease switching ripple and ripple-related conduction loss. When the load decreases, the controller decrease switching frequency to diminish switching loss and increase switch life cycle. In this paper, the flyback and push-pull converter topologies are simulated using MATLAB/Simulink and the results obtained from the variable switching converter are compared with the results obtained from constant switching frequency. Keywords: Green Mode Operation, Flyback Converter, Push-Pull Converter, Variable Switching Frequency, Constant Switching Frequency.

Green Supply Chain Performance Measurement using Green SCOR Model in Agriculture Industry: A Case Study

The agriculture industry has proliferated in the last decades, increasing the envi­ron­mental footprint. Several development concepts include integrating the ecological aspect into the supply chain to reduce environmental degradation. In implementing the idea, companies in the agriculture industry need to evaluate their performance in the environmental area. This measure­ment uses the Green Supply Chain Operations Reference (GSCOR) Model that provides its entire supply chain aspect. This study demonstrates that the enable parameter criterion, which shows the magnitude of employee management toward environmental requirements, significantly impacts supply chain performance. Other criteria are also critical, such as a plan that considers every entity's usage and a source that considers the supply of the entities. The performance measurement produces a 6.357 value in the yellow color category with an average condition in the company. It produces three key performance indicators (KPI), such as water usage, percentage hazardous materials in inventory, and percentage hazardous waste, with a red classification that should be improved.

Effect of Pd-Sensitization on Poisonous Chlorine Gas Detection Ability of TiO2: Green Synthesis and Low-Temperature Operation.

Ganoderma lucidum mushroom-mediated green synthesis of nanocrystalline titanium dioxide (TiO2) is explored via a low-temperature (≤70 °C) wet chemical method. The role of Ganoderma lucidum mushroom extract in the reaction is to release the ganoderic acid molecules that tend to bind to the Ti4+ metal ions to form a titanium-ganoderic acid intermediate complex for obtaining TiO2 nanocrystallites (NCs), which is quite novel, considering the recent advances in fabricated gas sensing materials. The X-ray powder diffraction, field emission scanning electron microscopy, Raman spectroscopy, and Brunauer–Emmett–Teller measurements etc., are used to characterize the crystal structure, surface morphology, and surface area of as-synthesized TiO2 and Pd-TiO2 sensors, respectively. The chlorine (Cl2) gas sensing properties are investigated from a lower range of 5 ppm to a higher range of 400 ppm. In addition to excellent response–recovery time, good selectivity, constant repeatability, as well as chemical stability, the gas sensor efficiency of the as-synthesized Pd-TiO2 NC sensor is better (136% response at 150 °C operating temperature) than the TiO2 NC sensor (57% at 250 °C operating temperature) measured at 100 ppm (Cl2) gas concentration, suggesting that the green synthesized Pd-TiO2 sensor demonstrates efficient Cl2 gas sensing properties at low operating temperatures over pristine ones.
