Transportation Of Commodities Research Articles

Machine learning-based anomaly detection and prediction in commercial aircraft using autonomous surveillance data.

Regarding the transportation of people, commodities, and other items, aeroplanes are an essential need for society. Despite the generally low danger associated with various modes of transportation, some accidents may occur. The creation of a machine learning model employing data from autonomous-reliant surveillance transmissions is essential for the detection and prediction of commercial aircraft accidents. This research included the development of abnormal categorisation models, assessment of data recognition quality, and detection of anomalies. The research methodology consisted of the following steps: formulation of the problem, selection of data and labelling, construction of the model for prediction, installation, and testing. The data tagging technique was based on the requirements set by the Global Aviation Organisation for business jet-engine aircraft, which expert business pilots then validated. The 93% precision demonstrated an excellent match for the most effective prediction model, linear dipole testing. Furthermore, the "good fit" of the model was verified by its achieved area-under-the-curve ratios of 0.97 for abnormal identification and 0.96 for daily detection.

Identifying mïmï as ‘Linseed’

Summary mïmï appears to have diverse applications, appearing in administrative documents, jar labels, depictions of commodity transportation, as well as being used in therapeutic recipes. To date, a consensus for its translation has not been reached. This article re-evaluates the suitability of past identifications in terms of new perspectives in Egyptology, and explores an extended corpus of source material that together suggest a new identification, ‘linseed’, is more appropriate. The hypothesis is further supported through the recreation and discussion of the materiality of ancient Egyptian medical recipes composed of mïmï and other ingredients with secure translations, and demonstrates: 1) that linseed was a commodity which was taxed, stored, and distributed by the ancient Egyptian administration; 2) that the effect of this product upon the body was observed and harnessed in therapeutic medical recipes.

Minimum Space When Transporting Pigs: Where Is the "Good" Law?

This paper focuses on the problem of numeracy when writing regulations, specifically how to describe a threshold for crowding of pigs during transport, considering transported pigs range in body mass from 5 to 500 kg. When scientific findings provide the basis for regulation in the public interest, those findings must be communicated in a consistent way to regulators and policymaking bodies. Numeracy is the ability to understand, reason with, and apply appropriate numerical concepts to real-world questions. Scientific understanding is almost always based on rational understanding of numerical information, numeracy. The threshold of administrative offenses is often a numerical description. Commercial livestock transporters have an interest in loading livestock compartments to the maximum to achieve the largest payload allowed by axle weight laws, as is the case in all bulk commodity transport. Maximizing payload minimizes costs and environmental hazards of fuel exhaust and can benefit the public with lower pork prices, but has a serious animal welfare risk. Livestock production academics, veterinarians, and animal welfare activists have been working for decades to determine the level of livestock crowding in transport containers that would be appropriate for regulatory enforcement. The scientific discourse has been plagued by a lack of numerical standardization when describing results of trials and forming recommendations. Exceeding specific numerical thresholds is the core to implementing enforcement actions. This paper examines the communication and other barriers that have prevented emergence of a consensus on this question and provides a direction toward resolution. Further confirmation of effects of crowding livestock in transit is needed. This paper suggests that articulating an enforceable standard in pig transport is possible. In inspection for compliance, discovering the LP50 (lethal pressure-50) for slaughter-weight pigs is an initial global benchmark goal. The LP50 is the loading floor pressure in a commercial transport compartment, under field conditions, that would result in the death of at least one pig in the group 50% of the time.

A Multiperiod, Multicommodity, Capacitated International Agricultural Trade Network Equilibrium Model with Applications to Ukraine in Wartime

The world is facing immense challenges because of increasing strife and the impacts of climate change with accompanying disasters, both sudden-onset as well as slow-onset ones, which have affected the trade of agricultural commodities needed for food security. In this paper, a multiperiod, multicommodity, international, agricultural trade network equilibrium model is constructed with capacity constraints on the production, transportation, and storage of agricultural commodities. The model allows for multiple routes between supply and demand country markets, different modes of transport, and storage in the producing and consuming countries as well as in the intermediate countries. The generality of the underlying functions, coupled with the capacity constraints, allow for the modeling of competition among agricultural commodities for production, transportation, and storage. The capacity constraints also enable the quantification of various disaster-related disruptions to production, transportation, and storage on the volumes of commodity flows as well as on the prices. A series of numerical examples inspired by the effects of Russia’s full-scale invasion of Ukraine on agricultural trade is presented, and the results are analyzed to provide insights into food insecurity issues caused by the war.

Numerical Investigation of the Flow Structure of Cryogenic Hydrogen in Corrugated Metal Flexhoses Due to Fluid Structure Interactions

Abstract In this paper, details of flow field characteristics and pressure drop of cryogenic hydrogen in corrugated metal flexhoses will be numerically evaluated using multiphase flow physics coupled with fluid structure interactions. Multiphase flow regime is often influenced by concentration ratio, shape factor, and orientation of the piping. Corrugated metal flexhoses are commonly used as part of cryogenic commodity transportation for their ability to operate in a large range of temperatures and pressures with a high degree of geometric flexibility. These sharp changes in the geometry of the flexhose convolutions are one of the leading factors of liquid and gas phase entrainment which can significantly reduce the efficiency of piping systems and fuel delivery systems to the engine components. The entrained gas phase hydrogen can eventually propagate in successive convolutes leading into the permanent entrapment of the gas phase hydrogen in the corrugations. The volume fraction up to 5% gas phase with various convolute heights and pitch will be evaluated, with a hose length to diameter ratio (L/D) range between 20 to 60 and a Reynolds number range between 5,000 to 350,000 based on the hose hydraulic diameter. The findings of the study contribute to a better understanding of multiphase flow physics of hydrogen in corrugated metal flexhoses.

Sustainable operation of on-street parking within Hilla City by Simulation Model (VISSIM) with Surrogate Safety Assessment Model (SSAM)

Abstract The preservation of sustainability poses an ongoing and persistent problem. To attain sustainability, it is imperative to prioritize the preservation of road traffic safety, the prevention of crashes, the utilization of pollution-free vehicles, and the secure transportation of commodities. The research approach employed in this study involves collecting data about many factors, including air pollution, noise levels, incident frequency, and traffic volumes. The study focuses on 20 links with on-street parking facilities in Hilla City, Iraq. This study uses the VISSIM microsimulation model SSAM software. This study used PTV VISSIM (Thesis) 2024 (SP 02). This license(Thesis) of PTV VISSIM software enables one to conduct the research unlimitedly, which is good for obtaining accurate results. The simulation time used in this study is 3600 seconds. PTV ViSSIM software enables the emulation of traffic movements on selected streets that contain on-street parking. Six streets in Hilla City are divided into 20 links. The streets were monitored using video recordings to collect real traffic data, which was then used to estimate delay and emissions. Additionally, trajectory files were created for future analysis. The SSAM program can be used to determine the conflicts in each link. The simulation models were effectively calibrated and validated using actual data. This study assesses the sustainable, social, economic, and environmental aspects of roadways, including on-street parking spaces. This project intends to construct a sustainable composite index utilizing existing data collection methods. Existing data on urban transportation sustainability considers economic factors like delay, social factors like safety, and environmental factors like noise and air pollution. The composite sustainability index incorporates economic, social, and environmental data, effectively tackling the difficulties related to normalization, weighting, and aggregation. This study aims to evaluate the long-term viability of transportation in Hilla’s central business area (CBD) by considering the incorporation of on-street parking. The Composite Sustainability Transportation Index (ICST) results for links with on-street parking in Hilla City indicate that the sustainability operation is evaluated at different levels: low (8 links), moderate (7 links), and high (5 links).

Regulatory Framework on Ocean Threats –Transportation Law Analysis to Multiple Oil-Spill Cases in Indonesia

This research aims to analyse the legislation pertaining to the environment and transportation as outlined in Article 1 point 1 of Law No. 22 of 2001, which deals with oil and natural gas. The Minister of Energy and Mineral Resources' Regulation No. 7 of 2019 Article 1.2 relates to the management and use of oil and gas. Articles 316, 318-322, 324-329, and 332 govern criminal offenses committed in the maritime domain. This study employs a doctrinal legal research methodology, using both conceptual approach and statutory approach. The agreement for the maritime transportation of commodities establishes rights and duties that the involved parties are required to fulfill. One of the duties and liabilities of the carrier is to maintain the security of the vessel and the merchandise it transports. The legal framework governing the transportation of commodities is established under Articles 466 to 520 of the Criminal Code. This concept is founded upon two additional ideas, i.e. strict liability and the absence of the necessity to establish the party responsible for environmental damage prior to attributing blame. The principle of strict responsibility in Indonesian national law is governed by Article 88 of Law No. 32 of 2009, which pertains to environmental protection and management. This article only focuses on the environmental degradation and marine contamination resulting from oil spills. The obligation for transportation in maritime agreements and the legal repercussions for causing marine pollution must be followed by all the sea transportations company especially carrying dangerous material.

Ethylene Elimination Using Activated Carbons Obtained from Baru (Dipteryx alata vog.) Waste and Impregnated with Copper Oxide.

Ethylene is a plant hormone regulator that stimulates chlorophyll loss and promotes softening and aging, resulting in a deterioration and reduction in the post-harvest life of fruit. Commercial activated carbons have been used as ethylene scavengers during the storage and transportation of a great variety of agricultural commodities. In this work, the effect of the incorporation of copper oxide over activated carbons obtained from baru waste was assessed. Samples were characterized by X-ray diffraction (XRD), N2 adsorption-desorption at -196 °C, field-emission scanning electron microscopy (FESEM) coupled with energy-dispersive X-ray spectroscopy (EDS), and infrared (IR) spectroscopy. The results showed that the amount of ethylene removed using activated carbon obtained from baru waste and impregnated with copper oxide (1667 μg g-1) was significantly increased in comparison to the raw activated carbon (1111 μg g-1). In addition, carbon impregnated with copper oxide exhibited better adsorption performance at a low ethylene concentration. Activated carbons produced from baru waste are promising candidates to be used as adsorbents in the elimination of ethylene during the storage and transportation of agricultural commodities at a lower cost.

Expansion of fluvial transport of commodities through the Pantanal floodplains of Brazil: Potential impacts and interference by climate change

AbstractInland waterways have historically been viewed as a desirable means for transporting commodities. However, creating and maintaining navigable river channels can entail substantial geomorphological modifications, resulting in changes to the ecohydrology of a river and its adjacent floodplains. In addition, barge traffic has important environmental impacts. The proposed expansion of the Paraguay River Hidrovia through the Pantanal floodplains of Brazil will negatively impact biodiversity due to bank erosion, water pollution, and the introduction of invasive species. Dredging would decrease the area and duration of inundation of connected floodplains renowned for their biodiversity, including fish and wildlife. Furthermore, the effects of the Hidrovia on greenhouse gas emissions are potentially important, although the net effects are complex and require further research. Global climate change is projected to cause greater variability in rainfall and river levels, with longer and more severe low water periods that would impede navigability and require further channel modifications. Modifications of the Paraguay River channel that lower the water levels and reduce the extent of surface water persisting during the dry season would negatively impact aquatic life in the main channel as well as in the floodplains, where recent increases in wildfire severity and excessive heat are already stressors. These changes threaten traditional livelihoods for people in the Pantanal, including artisanal fisheries, cattle ranching, and ecotourism.

A Forgotten Maritime Highway: Maritime Cultural Heritage of the Emperor Seamounts with Implications for High Seas Conservation

AbstractThis article seeks to complement efforts to summarize information on the exceptional natural significance of the Emperor Seamounts. The human history of the Emperor Seamounts is culturally diverse and spans thousands of years. This ranges from indigenous cultures to the period of European colonial exploration and expansion to the rise of the modern global economy and its impact on the area through the hunting of marine mammals, fishing, and the transportation of commodities across these remote waters on ships. Some of these vessels were wrecked or disappeared, and may rest on the seabed of the Emperor Seamounts. Understanding this human history is critical in approaching the assessment, ongoing study, public outreach and management of this remote region, which has been highlighted as one of the most important areas beyond national jurisdiction to protect globally.

Finding Optimal Location Development UPPKB In South Sumatera Province Using Multi-Criteria Analysis

The distribution of commodity transportation is a crucial factor for the sustainability and continuity of economic activities in specific regions. Shipments occur daily, especially on main roads, with the majority of goods transported exceeding tonnage limits when passing through roads. If this continues without control and security measures, it will lead to a deterioration of the physical quality of the road, disrupting the distribution of goods transportation. The Vehicle Weighing Station (UPPKB) is a form of control and security implemented by the government to regulate the transportation of goods distribution above tonnage limits. Every day, the transportation of goods distribution in South Sumatera Province is significant due to its numerous power plants and tourist destinations. This research aimed to identify the location for the development of UPPKB using a quantitative method to obtain indicators for multi-criteria analysis. The conclusion drawn from the identified potential points indicates positive results, making it feasible to construct a new UPPKB at those locations. The potential locations for the development of a new UPPKB in South Sumatera are Betung 1 Street and Yusuf Singadekane 1 Street

Predictive Analysis of Maritime Congestion Using Dynamic Big Data and Multiscale Feature Analysis

The maritime industry is one of the most crucial sectors in the global economy, facilitating the transportation of goods and commodities across vast distances. However, maritime network congestion has become an increasingly critical challenge that significantly affects shipping efficiency and the overall operational performance of the industry. This study proposes an innovative congestion prediction approach using dynamic big data analysis of vessel trajectories and multiscale feature analysis. First, the dynamic analysis of vessel trajectories aims to extract valuable information from ships’ data as they navigate the oceans, enabling proactive traffic management and optimized routing. Second, the multiscale feature analysis provides a comprehensive understanding of maritime network congestion by examining it from different perspectives and scales, leading to more accurate predictions and effective congestion management strategies. Furthermore, this study introduces an enhanced Faster R‐CNN vessel detection model for real‐time tracking, integrating convolutional and SKNet networks. To improve short‐term traffic flow prediction accuracy, this study employs multiscale feature analysis through wavelet transformation. The foundational traffic data undergo wavelet decomposition for a detailed representation across frequencies. Gated recurrent unit (GRU) neural network and autoregressive moving average (ARMA) models are utilized to predict trend and noise components, respectively. Fusion of predictions demonstrates superior accuracy and is validated against real data. Empirical results showcase minimal errors and heightened prediction accuracy compared to actual data.

New findings of terrestrial arthropods from the Azorean Islands.

The knowledge on taxonomic diversity of arthropods is key to better understanding the biodiversity patterns and processes and guiding sustainable conservation strategies and practices. In the Azores, terrestrial arthropods are relatively well-inventoried following the publication of comprehensive checklists that have been regularly updated. Nevertheless, every year, new species are found as a result of new arrivals to the Archipelago and from addressing specific taxonomic lacunae. Here, we update the taxonomic terrestrial arthropod biodiversity of the Azores by reporting for the first time 13 species for the Archipelago, namely Oligonychusperseae Tuttle, Baker & Abbatiello, 1976, Textrixpinicola Simon, 1875, Pholcommagibbum (Westring, 1851), Schistocercagregaria (Forsskål, 1775), Phoracantharecurva Newman, 1840, Diachusauratus Fabricius, 1801 Phyllotretaprocera (Redtenbacher, 1849), Phyllotretastriolata (Fabricius, 1803), Diboliaoccultans (Koch, 1803), Pseudolynchiacanariensis (Macquart, 1839), Hermetiaillucens (Linnaeus, 1758), Dryocosmuskuriphilus Yasumatsu, 1951 and Ectemniuscephalotes (Olivier, 1792), and several new species records for specific islands. These species benefitted from the increase in transportation of goods and commodities, both from outside the Archipelago and between islands, to arrive and spread across the Archipelago with some of them posing new challenges to local agriculture, forestry and biodiversity conservation management.

Политика против декарбонизации

This study describes the methodology and results of calculating the increase in global greenhouse gas emissions caused by disruptions in international logistics due to geopolitical restrictions introduced by Western countries against Russia since 2022. The Western sanctions policy regarding, first of all, trade in Russian hydrocarbons has caused the breakdown of trade routes, which until recently could be characterized as “conditionally optimal.” That is, hydrocarbon supplies were carried out along the shortest routes, which ensured minimal fuel combustion during transportation and minimal greenhouse gas emissions, respectively. Now, a forced reorientation has led to an increase in commodity transport work, which requires more fuel combustion and, accordingly, provides an increase in emissions. Closed airspace also has an additional negative effect on rising emissions, as most flights from Europe to Asia and back from 2022 will overfly Russia, which on average adds an extra 2 hours to the flight, requires more fuel to be burned, and therefore leads to increase in greenhouse gas emissions. And considering that flights have only just begun to recover after the 2020 crisis, the impact of the closure of airspace over Russia on greenhouse gas emissions will only grow in the future. The study’s calculations show that reorienting trade in oil and natural gas and extending air routes alone would increase emissions by 261–290 Million t of CO2 eq. This is comparable to the UK’s annual emissions. If we take into account all the distortions in global trade, emissions growth could be even 40–60% higher. Thus, it can be argued that existing trade restrictions brought a significant negative impact on the implementation of global low-carbon development agenda.
