Evaluating the Applicability of Mainstream Wave Energy Converters in the South China Sea

Based on the past ten years of ERA5 wave field data, this study analyzed the distribution of wave energy resources in the coastal waters of each province around the South China Sea. In view of the single resource evaluation method, a regional classification method was established that comprehensively considered the three factors that impact wave energy resource reserves, the suitable water depth of the wave energy conversion device, and the device layout mode that affects energy absorption efficiency. From this information, the locations of key deployment stations around the coastal provinces were determined. Additionally, the CRITIC method was used to build indicators that can comprehensively evaluate the performance of different devices, and the most suitable devices for deployment in the five provinces were identified. The wave energy propagation direction of each key station was analyzed. The results show that the wave energy propagation direction of each station is relatively concentrated, which is convenient since this helps the device absorb and utilize energy more efficiently. Finally, the power generation performance and economic benefits of each key station’s most suitable device were analyzed. This article provides an assessment of the applicability of mainstream wave energy conversion devices in the nearshore area of the South China Sea, which is of great significance for the development and utilization of wave energy resources in the South China Sea’s nearshore waters. It provides a scientific basis for the selection, deployment, operation, and other practical operations of the follow-up devices in the South China Sea, as well as the power generation performance and economic benefits of the devices.

Concurrent 24. Presentation for: The infrastructure of net zero: a unique challenge for Australia

Presented on Thursday 19 May: Session 24 In August 2021, Worley and Princeton University’s Andlinger Center for Energy and the Environment published a report titled ‘From ambition to reality: Weaving the threads of net-zero delivery’ which examined the challenge of building the assets of net zero. It used as a basis Princeton’s Net-Zero America study which detailed a number of pathways to achieve net-zero, finding for all an enormous infrastructure challenge – like nothing the world has ever seen. This joint publication considered the complex execution challenge of delivering this infrastructure. Extrapolating these results to the world economy, it was obvious that if infrastructure was delivered using historical, linear development and deployment paths then it would not be possible to reach net zero by 2050 regardless of which technology pathway was used. The joint publication developed five key shifts in practice that could bridge the gap between net zero ambition and reality. In this paper we explore the implications of this for the Australian energy markets, focusing on energy exports and the decarbonisation technologies most relevant to the oil and gas sector assuming a net zero ambition. In particular, we consider the shifts that will be needed to deliver these technologies, focusing on key deployment levers that may prove pivotal to meeting this ambition.

Socio-Economic Determinants for Biochar Deployment in the Southern Highlands of Tanzania

Biochar may contribute to both agricultural productivity and atmospheric carbon dioxide removal. However, despite the many potential upsides of adding biochar to amend carbon-depleted soils in sub-Saharan Africa, deployment is largely lacking. This paper explores the socio-economic factors that can explain tendencies to avoid action. Based on a survey of 172 farming households, key informant interviews, and focus group discussions in the Mbeya and Songwe regions of Tanzania, which were targeted for a biochar aid program in 2014, several socio-economic drivers behind the continued use of biochar deployment were identified in this follow-up study. A key deployment driver was the increased crop yields, perceived to be the result of adding biochar to soils, increasing yields from 1 metric ton per hectare to 3 metric tons per hectare. Food security and family income were cited as the main reasons to engage in biochar production and use. Climate change mitigation and increased resilience were other key reasons that motivated adoption. In terms of socio-economic factors, farmers with low education and income, the majority being males aged 40–60 years, contributed to low adoption rates in the study area. Respondents often cited the alternative usage of biochar feedstocks, lack of government involvement or extension services, traditions, and farming customs as the main constraints limiting biochar deployment.

Analysis on the Development Status of Intelligent and Connected Vehicle Test Site

With the development of automobile intelligence and connectivity, Intelligent and Connected Vehicle (ICV) is an inevitable trend in the transformation and upgrading of the automotive industry. The maturity of any advanced technology is inseparable from a large number of test verifications, especially the research and application of automotive technology require a large number of reliable tests for evaluation and confirmation. Therefore, the ICV Test Site (ICVTS) will become a key deployment area. In this paper, we analyze the development status of ICVTS outside and within China, summarize the shortcomings of the existing test sites, and put forward some targeted suggestions, in an effort to guide the development and construction of ICVTS towards the path that seems to be most promising.

Development trend of protection technology for oil storage tank

Petroleum is the lifeline of the national economy and an important strategic resource for the survival and development of the country. Nowadays, the main way of storage of raw materials and products in the petroleum and petrochemical industry is tank storage, so the operation, maintenance and anti-corrosion of storage tanks play a vital role in the industrial safety of the entire industry. This paper summarizes the development of tank anti-corrosion technology in petrochemical industry at present, discusses the mechanism of tank inside and outside corrosion, various anti-corrosion measures, highlights the importance of tank anti-corrosion protection, and looks forward to the future development of tank anti-corrosion technology. Petroleum is the blood of modern industry and serves the national energy security. The anti-corrosion measures of storage tanks are of great significance to the key deployment of strategic oil reserves in China.

Joint Routing and Resource Allocation for Millimeter Wave Picocellular Backhaul

Picocellular architectures are essential for providing the spatial reuse required to satisfy the ever-increasing demand for mobile data. A key deployment challenge is to provide backhaul connections with sufficiently high data rate. Providing wired support (e.g., using optical fiber) to pico base stations deployed opportunistically on lampposts and rooftops is impractical, hence wireless backhaul becomes an attractive approach. A multihop mesh network comprised of directional millimeter (mm) wave links is considered here for this purpose. Such networks are well suited for scaling backhaul data rates due to the abundance of spectrum in the mm wave bands, and the ability to form highly directional, electronically steerable beams. The backhaul design problem is formulated as one of joint routing and resource allocation, accounting for mutual interference across simultaneously active links. A computationally tractable formulation is developed by leveraging the localized nature of interference and the provable existence of a sparse optimal allocation. Numerical results are provided for topologies modeling urban and suburban settings.

LISA: Visible light based initialization and SMS based authentication of constrained IoT devices

Future healthcare systems, smart homes, power managementsystems will all involve a large number of smart inter-connected wireless devices (such as wireless sensor and IoT nodes). One of the major challenges to securing these systems presents loading initial cryptographic credentials into a relatively large number of wireless devices. This challenge is further aggravated by the fact that many of these technologies and systems involve low-cost and highly interface constrained devices — lacking usual wired interfaces, displays, keypads, and alike.In this paper we propose two novel multichannel key deployment schemes for wireless (sensor) networks, LISA and LISAT, that only require a presence of a light source device, such as a multi-touch screen, tablet or a smartphone device. Both key deployment schemes are secret key-based multichannel protocols and are suitable for interface/resource constrained wireless devices. We use one-way visible light channel (VLC) of multitouch screens (the flashing displays) to initialize sensor devices in a secure, usable and scalable way. More interestingly, LISAT protocol is suited for initialization of geographically remote devices via a trusted third party device. We provide formal analysis of the proposed protocols using the automated verification tool. From the user’s perspective of protocol execution, device initialization is quite simple as user simply places the devices on the top of the multitouch screen after which the remaining process is fully automatized. Indeed, through the experiments with 34 users we showed that our solution is user-friendly and has a good performance concerning the time consumption.

Wireless Power Transfer With Magnetic Resonator Coupling and Sleep/Active Strategy for a Drone Charging Station in Smart Agriculture

Drones can be used in agriculture applications to monitor crop yield and climate conditions and to extend the communication range of wireless sensor networks in monitoring areas. However, monitoring the climate conditions in agriculture applications faces challenges and limitations, such as drone flight time, power consumption, and communication distance, which are addressed in this study. Wireless power transfer (WPT) can be used to charge drone batteries. WPT using a magnetic resonant coupling (MRC) technique was considered in this study because it allows high transfer power and efficiency with tens of centimeters, power transfers can be achieved in misalignment situations, charging several devices simultaneously, and unaffected by weather conditions. WPT was practically implemented based on a solar cell using a proposed flat spiral coil (FSC) in the transmitter circuit and multiturn coil (MTC) in a receiver circuit (drone) for the alignment and misalignment of two coils at different distances. FSC and MTC improved power transfer and efficiency to 20.46 W and 85.25%, respectively, at 0 cm with the loaded system under alignment condition. In addition, the two coils achieved appropriate transfer efficiencies and power for charging the drone battery under misaligned conditions. The maximum power transfer and efficiency were 17.1 W and 71% for the misalignment condition, at an air gap of 1 cm between two coils when the system was loaded with the drone battery. Moreover, the battery life of the drone was extended to 851 minutes based on the proposed sleep/active strategy relative to the traditional operation (i.e., 25.84 minutes). Consequently, a 96.9% battery power saving was achieved based on this strategy. Comparison results showed that the proposed system outperformed some present techniques in terms of the transfer power, transfer efficiency, and drone battery life. The proposed WPT technique developed in this study has been proven to solve the misalignment issue. Thus it offers a great opportunity as a key deployment component for the automation of farming practices toward the Internet of Farming applications.

A review of acoustic telemetry in Europe and the need for a regional aquatic telemetry network

BackgroundGlobally, there are a large and growing number of researchers using biotelemetry as a tool to study aquatic animals. In Europe, this community lacks a formal network structure. The aim of this study is to review the use of acoustic telemetry in Europe and document the contribution of cross-boundary studies and inter-research group collaborations. Based on this, we explore the potential benefits and challenges of a network approach to identify future priorities and best practices for aquatic biotelemetry research in Europe.ResultsOver the past decade, there was an approximately sevenfold increase in the number of acoustic telemetry studies published on marine and diadromous species in Europe compared to a sixfold increase globally. Over 90% of these studies were conducted on fishes and undertaken in coastal areas, estuaries, or rivers. 75% of these studies were conducted by researchers based in one of five nations (Norway, UK, France, Portugal, and Spain) and, even though 34% were based on collaborations between scientists from several countries, there was only one study with an acoustic receiver array that extended beyond the borders of a single country. In recent years, acoustic telemetry in European waters has evolved from studying behavioural aspects of animals (82.2%), into more holistic approaches addressing management-related issues (10%), tagging methods and effects (5%), and technology and data analysis development (2.8%).ConclusionsDespite the increasing number of publications and species tracked, there is a prominent lack of planned and structured acoustic telemetry collaborations in Europe. A formal pan-European network structure would promote the development of (1) a research platform that could benefit the acoustic telemetry community through capacity building, (2) a centralized database, and (3) key deployment sites and studies on priority species requiring research in Europe. A network may increase efficiency, expand the scope of research that can be undertaken, promote European science integration, enhance the opportunities and success of acquiring research funding and, ultimately, foster regional and transatlantic collaborations. It may also help address research priorities such as the large-scale societal challenges arising from climate change impacts and assist the EU’s Marine Strategy Framework Directive via identification of good environmental status of endangered or commercially important species.

Impact of Interference Between Neighbouring 5G Micro Operators

Local small cell deployments will become an important part of the future 5G networks, in particular in the higher frequency bands. In order to speed up the wide-spread deployment of such ultra-dense networks, new business and spectrum authorization models are needed. The recently proposed concept of micro operators with local spectrum micro licensing has gained significant interest in research, industry and regulation to complement the traditional models based on networks deployed and operated by the mobile network operators. While assessing the applicability of the proposed micro operator concept, one important aspect is to evaluate the impact of the inter-operator interference on the performance of the victim network when deployed in the same or adjacent channel. To support such interference evaluations between micro operators, this paper proposes a deployment scenario including two neighbouring buildings, propagation models for connections both within a building and between the buildings, and a criteria for the required minimum separation distance based on the observed throughput loss. Finally, system simulations are performed to evaluate the impact of the key deployment aspects on the required minimum separation distance between the micro operators in the 3.5 GHz band. The obtained results indicate that the required minimum separation distances are highly scenario-specific, which needs to be considered in the overall local spectrum micro licensing model development and the setup of appropriate rules to coordinate the interference.

Formal verification: will the seedling ever flower?

In one sense, formal specification and verification have been highly successful: techniques have been developed in pioneering academic research, transferred to software companies through training and partnerships, and successfully deployed in systems with national significance. Altran UK has been in the vanguard of this movement. This paper summarizes some of our key deployments of formal techniques over the past 20 years, including both security- and safety-critical systems. The impact of formal techniques, however, remains within an industrial niche, and while government and suppliers across industry search for solutions to the problems of poor-quality software, the wider software industry remains resistant to adoption of this proven solution. We conclude by reflecting on some of the challenges we face as a community in ensuring that formal techniques achieve their true potential impact on society.This article is part of the themed issue 'Verified trustworthy software systems'.

Design of 20 W fiber-coupled green laser diode by Zemax**Project supported by the National Key R& D Program of China (No. 2016YFB0402105), the Key Deployment Program of the Chinese Academy of Sciences (No. KGZD-SW-T01-2), and the National Natural Science Foundation of China (No. 61404135).

We represent a design of a 20 W, fiber-coupled diode laser module based on 26 single emitters at 520 nm. The module can produce more than 20 W output power from a standard fiber with core diameter of 400 μm and numerical aperture (NA) of 0.22. To achieve a 20 W laser beam, the spatial beam combination and polarization beam combination by polarization beam splitter are used to combine output of 26 single emitters into a single beam, and then an aspheric lens is used to couple the combined beam into an optical fiber. The simulation shows that the total coupling efficiency is more than 95%.

Coherent Transfer of Optical Frequency over 112 km with Instability at the 10−20 Level**Supported by the Special Fund for Major Scientific Equipment and Instrument Development of the National Natural Science Foundation of China under Grant No 61127901, the National Natural Science Foundation of China under Grant Nos 10225417, 11273024, 61025023 and 91636101, the Young Scientists Fund of the National Natural

We demonstrate optical-carrier transfer over a 112-km single-span urban fiber link. By actively compensating the phase noise induced along the fiber link, a noise suppression of 55 dB at 1 Hz is obtained. A fractional frequency instability of 2.5 × 10−16 at 1s is achieved, and reaching 7.5 × 10−20 at 10000 s. The system is stable and able to run for a long time. This work will contribute to optical frequency distribution and remote comparison among atomic clocks.

Evaluation of new large area PMT with high quantum efficiency*Supported by Strategic Priority Research Program of Chinese Academy of Sciences (X-DA10010200), Key Deployment Project of Chinese Academy of Sciences and CAS Center for Excellence in Particle Physics (CCEPP)

The neutrino detector of the Jiangmen Underground Neutrino Observatory (JUNO) is designed to use 20 kilotons of liquid scintillator and approximately 16 000 20 inch photomultipliers (PMTs). One of the options is to use the 20 inch R12860 PMT with high quantum efficiency which has recently been developed by Hamamatsu Photonics. The performance of the newly developed PMT preproduction samples is evaluated. The results show that its quantum efficiency is 30% at 400 nm. Its Peak/Valley (P/V) ratio for the single photoelectron is 4.75 and the dark count rate is 27 kHz at the threshold of 3 mV while the gain is at 1 × 107. The transit time spread of a single photoelectron is 2.86 ns. Generally the performances of this new 20 inch PMT are improved over the old one of R3600.

Early Hydrogen Station Economics Analysis

Deployment of the hydrogen supply infrastructure is one of most critical issues that must be addressed for a successful market transition to fuel cell electric vehicles (FCEV). Not only must hydrogen refuelling infrastructure be constructed, it must also be commercially viable and sell hydrogen to customers at retail prices that will encourage the continued expansion of the vehicle market. The objective of this study is to develop a station deployment optimization model and analyze station network economics and risk of investment. The model optimizes key deployment decisions to meet fuel demand by trading off infrastructure cost and fuel accessibility cost. Decision variables are when, where to build and the size of stations. Fuel accessibility cost is relative to gasoline, measured by additional detour time in order to access hydrogen refuelling stations. A case study is conducted for the City of Santa Monica in California. Deployment schemes generated from the optimization model are relatively robust to assumed level of fuel inconvenience cost, suggesting that the importance of station scale economy outweighs fuel convenience, subject to the caveats of model limitations. The model does not capture the dynamic interaction between vehicle demand and refuelling convenience. If vehicle demand was modelled endogenously, the importance of refuelling convenience would be valued higher by the model. Another factor might be that the area of study is small, which limits potential detour time savings that could be achieved from adding more stations. Cash flow analysis results suggest that the station network at the study area (the city of Santa Monica) may endure negative cash flows for about a decade. Driving patterns of early FCEV adopters matter to the economics of city station network. If FCEV users on average have long annual driving distance and trips are concentrated within the region, the profitability of local station networks would be improved.

Flashing displays: user-friendly solution for bootstrapping secure associations between multiple constrained wireless devices

Future healthcare systems, smart homes, and similar will involve a large number of smart inter-connected wireless devices (such as wireless sensor nodes). One of the major challenges to securing these systems presents loading initial cryptographic credentials into a relatively large number of wireless devices. Furthermore, many of these technologies involve low-cost and highly interface constrained devices (lacking usual wired interfaces, displays, keypads, and alike). We propose two novel multichannel key deployment schemes for wireless networks that only require a presence of a light source device, such as a multi-touch screen (tablet or smartphone device). The first key deployment scheme is based on secret key cryptography and is suitable for interface/resource-constrained wireless devices. The second scheme assumes a strong attacker and requires the use of public key cryptography. In both our solutions, we use one-way visible light channel of multi-touch screens (flashing displays) to initialize devices in a secure, usable, and scalable way. From the user's perspective, this boils down to placing the devices on the multitouch screen after which the remaining process is fully automatized. We showed through the experiments with 48 users that our solution is user-friendly and scales linearly with the number of nodes. Copyright © 2015 John Wiley & Sons, Ltd.
