This paper gives an introduction to how StatoilHydro envisages the importance of technology development in an increased oil recovery perspective, and how this is reflected in our work process, i.e.:Defining the challenges and corresponding technology requirementsDevelop the identified technologies, alone or together with one or more service providersTake the technology into operation Increased reserves from IOR activities in mature fields often turn out to be the ‘cheapest and fastest’ way for an operator to find and develop new hydrocarbons. The alternative, which we also have focus on, is to assess exploration assets, perform exploration drilling and ultimately develop the field. StatoilHydro realizes that technology development is mandatory to increase reserves through IOR. As an operator StatoilHydro will not in this setting ‘sit back’ and wait for the suppliers to come up with new ideas. We want to define the type of technology required to meet our IOR ambitions and establish partnerships with selected institutes and service providers. When the technology is deemed necessary by the company's R&D organization, business assets and management, the basis for starting a structured R&D program is in place. Next phase is to select the supplier. We believe that the suppliers will also benefit from such a co-operation, as a successful project will provide a dedicated customer. Benefit from new technology comes with implementation. Key aspects to secure successful technology implementation are:Technology development required by one or more assets1st user specified early in the processFunding secured beyond the R&D budget We realize that there is a tendency that available new oil and gas reserves are becoming more and more marginal, both with respect to location (deep water, remote and cold areas) and reservoir quality (low permeability, high heterogeneity), as well as with respect to product quality (heavy oil, high H2S and CO2 content). As we see it, it is now time to focus even more on increased oil and gas recovery and the necessary technology development to release the full potential. Introduction This paper focuses on StatoilHydro's past and present strategy in developing and implementing IOR technologies. It also lists the technologies that have been key to increased recovery and gives indications regarding the way forward. Figure 1 shows how the ultimate recovery in a number of StatoilHydro assets has increased since the projects were sanctioned. The average ultimate recovery for all StatoilHydro operated oil fields is today approximately 50%. The recovery for developments based on dry wellheads is 10-12% points higher than the recovery in subsea developments. Even though these numbers are high compared to a world wide average, the ambition is to increase the recovery by an additional one billion barrels, corresponding to a major field development. Some important characteristics of IOR-volumes in mature fields are:Their presence are verified (no exploration in traditional sense is required)Significant infrastructure is already in placeThe knowledge of the reservoir is far better than for new developmentsThe economic boundary conditions are well known

Human memory at its best can perform astonishing feats - the tiniest snippet of information can trigger whole chains of associations, ending at an item long-believed forgotten. While modern information systems excel at systematic manipulation of structured or semi-structured information or even vast repositories of unstructured textual information, they are still far from these capabilities

Rangitoto is one of Auckland City’s more iconic landscape features. Guarding the entrance to the Waitemata Harbour, Rangitoto is a symmetrical, ~6-km wide, basaltic shield volcano that last erupted ~550 years ago shortly after the arrival and settlement of Polynesians in the Auckland region (c. 1280 AD). Rangitoto is by far the largest, and also the youngest, volcano in the Auckland Volcanic Field (AVF). The AVF is a monogenetic volcanic field consisting of approximately 53 individual eruptive centres, all of which are within the boundaries of the Auckland urban area. Recent research has revealed more about Rangitoto’s eruptive history, which may date back to c. 1500 years ago (Shane et al. 2013). Some of these findings have been noted below and will be discussed further while we ascend its summit and explore its various landscape and vegetational features

The Sendai Framework for Disaster Risk Reduction 2015–2030 was agreed at the Third UN World Conference on Disaster Risk Reduction in Sendai, Japan in March 2015 and endorsed by the UN General Assembly in June 2015. The goal of the Sendai Framework is to prevent new and reduce existing disaster risk. UNISDR coordinates and ensures synergies among the disaster reduction activities of the United Nations system and regional organizations and stakeholders The role of science and technology in providing the evidence and knowledge on risk features prominently in the Sendai Framework. Expanding the interface between science, technology and policy is therefore essential for effective disaster risk reduction. In January 2016, UNISDR hosted the Science and Technology Conference on the Implementation of the Sendai Framework. The main outcome of the conference was the launching of the Science and Technology Partnership and the endorsement of the science and technology roadmap that outlines expected outcomes, actions, and deliverables under each of the four priority actions of the Sendai Framework. Over the last twenty years, the majority of disasters have been caused by floods, storms, heatwaves and other weather-related events. Most of these disasters can cause landslides, which in turn cause hundreds of billions of dollars in damage and hundreds of thousands of deaths and injuries each year The International Consortium on Landslides (ICL) 2015–2025 and The Sendai Partnerships promotes global understanding and reduction of landslide disaster risk. They will contribute significantly to the implementation of the science and technology roadmap by providing practical solutions and tools, education and capacity building, and communication and public outreach to reduce landslides risks. UNISDR fully supports the work of the Sendai Partnerships and the community of practice on landslides risks

Today's trip to the Raglan district, western North Island, is primarily an introduction to (1) the Alexandra Volcanics, a group of chiefly basaltic deposits of Plio-Pleistocene age, and (2) the Kauroa and Hamilton Ash formations, two groups of weathered, predominantly rhyolitic, tephra beds of Plio-Pleistocene age that, in places, are intercalated with Alexandra Volcanics. Buried paleosols are associated with both the Alexandra and Kauroa/Hamilton deposits. We plan on spending around half the day at one site - Stop 5 - on the Karioi edifice on the west coast, just south of Raglan (Figs. 1.1, 1.5). Here we will examine, in a relaxed and informal manner, outcrops in and near Te Toto amphitheatre and gorge, a critical locality for understanding the stratigraphic succession and petrologic evolution of Karioi (see Fig. 1.9 below)

Federated Machine Learnig (FML) creates an ecosystem for multiple parties to collaborate on building models while protecting data privacy for the participants. A measure of the contribution for each party in FML enables fair credits allocation. In this paper we develop simple but powerful techniques to fairly calculate the contributions of multiple parties in FML, in the context of both horizontal FML and vertical FML. For Horizontal FML we use deletion method to calculate the grouped instance influence. For Vertical FML we use Shapley Values to calculate the grouped feature importance. Our methods open the door for research in model contribution and credit allocation in the context of federated machine learning.

We have a reasonably long day ahead of us, but it promises to be both interesting and relaxing. We will be examining a range of distal and proximal pyroclastic deposits including airfall and flow (ignimbrite) units derived from the Mangakino and Okataina Volcanic Centres, Taupo Volcanic Zone (TVZ), tephric loess deposits, and buried paleosols on tephra beds- in other words, something for everyone attending our three-discipline conference. As well, we shall see a variety of volcanic landforms both on our journey from Hamilton and in the Rotorua region itself. We finish the day with a 'Caldera Dinner' overlooking Rotorua and Haroharo calderas, and Mt Tarawera, from the top of Ngongataha rhyolite dome

Artificial intelligence (AI) is a promising technology to transform the healthcare industry. Due to the highly sensitive nature of patient data, federated learning (FL) is often leveraged to build models for smart healthcare applications. Existing deployed FL frameworks cannot address the key issues of varying data quality and heterogeneous data distributions across multiple institutions in this sector. In this paper, we report our experience developing and deploying the Contribution-Aware Federated Learning (CAFL) framework for smart healthcare. It provides an efficient and accurate approach to fairly evaluate FL participants' contribution to model performance without exposing their private data, and improves the FL model training protocol to allow the best performing intermediate models to be distributed to participants for FL training. Since its deployment in Yidu Cloud Technology Inc. in March 2021, CAFL has served 8 well-established medical institutions in China to build healthcare decision support models. It can perform contribution evaluations 2.84 times faster than the best existing approach, and has improved the average accuracy of the resulting models by 2.62% compared to the previous system (which is significant in industrial settings). To our knowledge, it is the first contribution-aware federated learning successfully deployed in the healthcare industry.

Hydrogen from hydrocarbon production and electricity is an important contribution to meet the energy demand in times of energy transition. As several oil and energy companies focus on a wider range of energy sources, the different hydrogen sources play an important role to meet the global energy demand. The development of new technology and competence is essential to manage handling of new energy sources. The hydrogen technology is so young as a fuel source, that legislation is a subject for current upgrading. So is the technology for storing and fuelling. The technology exploration in optimizing energy concentration, fuel cells, and energy transfer, are important research areas in university research centres in Norway and several other countries. Research in hydrogen energy source is performed by professors together with students at all levels. These students will in next turn fill the industry with new competences. As new energy sources are introduced, the energy transfer between different sources needs to be considered to plan the best and most economical way for transport and consume of hydrogen energy. All together these subjects are important new areas of competence that petroleum engineers need to achieve to fulfil the energy companies’ visions of delivering a wider range of energy. Several oil companies have already sent their engineers to academic programs to upgrade competence in hydrogen technology. When experienced petroleum engineers move back to universities to upgrade their skills to include hydrogen, the good collaboration and industry understanding are developed to the benefit of all parts. The training programs provided by Norwegian universities are under current development in close contact with the ongoing research at universities. This paper will focus how competence in new and upcoming energy technology may be realised in the playground where industry and academia play together. As the graph in Figure 1 shows, the renewable energy sources are in minority, but in a growing scale. The grow in the production and consume of renewable energy sources will have to increase rapidly, both to meet the global decisions of reducing CO2emission, and because they are renewable. The fossil fuel resources will not last forever. The most relevant institutions to perform the energy transition are the existing oil companies. Many of them define them self as energy companies. The energy companies have got the needed technology and competence to start the transition, but they will need support and collaboration with research and education institutions.

Ever since analyzing scientific topics and evolution of technology have become vital for researchers, academics, funding institutes and research administration departments, there is a crucial need to mine scientific trends to fill this appetite more rigorously. In this paper, we procured a novel Call for Papers (CFPs) dataset in order to analyze scientific evolution and prestige of conferences that set scientific trends using scientific publications indexed in DBLP. Using ACM CSS, 1.3 million publications that appear in 146 data mining conferences are mapped into different thematic areas by matching the terms that appear in publication titles with ACM CSS. In recent years, an attempt termed as Topic Detection and Tracking (TDT) [1] is made to find the solution for the problem of "well-awareness" on this dynamic data. As conference ranking has been made by different forums on the basis of mixed indicators1. ERA2 ranks Australia's higher education research institutions. The major contributions of this paper are as follows: (i) compilation of CFPs dataset, (ii) identification of topics and keywords from CFP corpus, and (iii) measure the impact of these extracted hot topics from CFPs

The pear ( Pyrus communis L.) cultivar, Conference, is parthenocarpic but misshapes and marketable fruit losses of 6% at harvest are common. In other studies, insect flower visitors are identified as important for apple quality, but far fewer studies have examined the effects of insects and cross-pollination on pear quality. Using a range of replicated field experiments, this project aimed to determine the; 1) biodiversity of pear blossom insect visitors, 2) pollen limitation and fruit quality as a function of distance from the orchard edge and number of insect visitors, and 3) importance of cross pollination on fruit quality. A wide range of insects, >30 species, visited pear flowers including honey bees, bumble bees, solitary bees and hoverflies. Honey bees were the most frequent visitors, but all guilds, to a greater or lesser extent, made contact with the reproductive parts of the flower. Insect visits resulted in ~10% higher fruit set. There was no effect of distance from the edge (up to 50 m) of orchard on the quality of pears, and no consistent difference in the guild of insects visiting at distances from the orchard boundary. Cross-pollination with the variety Concorde produced better quality Conference fruits. We discuss how pollination of Conference pears could be managed to improve yields of marketable fruit.

Whilst the primary purpose of conferences is work — formal exchange and sharing of information — they almost always also include elements of play: Informal social and entertainment elements, such as receptions, dinners, and tourism activities. These activities also provide the opportunity for ‘serious’ discussions, meeting people, and networking, and are an essential part of a good conference. Despite this, most virtual conferencing tools fail to provide support for such activities, instead focusing on austere goals related to saving money, time, and travel. This paper describes the concept of a Virtual Cocktail Party (VCP) tool to integrate into a virtual conference environment. In VCP the ‘party’ is presented as a mixture of individuals and small conversation groups ‘circulating’ at the virtual venue. Exploiting an automated speech-to-text system, words from conversations are shown in word-clouds displayed around conversation groups, sufficient to identify topics of conversation allowing participants to decide whether or not to join a group

©2024 RAYYAAN_RishadCommercial wind turbine (WT) blades that are now being operational globally, are primarily made of glass-reinforced composites using epoxy or polyester matrix systems, mainly epoxy. The industry is rapidly growing (2100 TWh currently; 17% growth annually) with a forecast of 7400 TWh by 2030. The average lifespan of a WT is 20-25 years, which signifies the importance of repairing the damaged blades. Amongst the methods that have been exploited so far, resistance welding shows eminent potential, due to its ease of operation, promptness of the repair process, and cost effectiveness. Resistance welding was exploited previously for repairing thermoplastic composites. But in this project, repair of thermoset composites was evaluated using thermoplastic welding medium. The project focused on parametric optimisation of resistance welding, evaluation of welding via single lap shear strength, and COMSOL multiphysics modelling to examine the homogeneity of heat-distribution across the welding region. Stainless steel mesh and carbon nonwoven sheet were used as heating elements, while polymethyl methacrylate and thermoplastic polyurethane were used as welding medium. The highest single lap shear strength was shown as 6.4 MPa when nonwoven carbon sheet was used along with thermoplastic polyurethane. COMSOL modelling with a custom-designed heating element showed improvement in thermal homogeneity; however, further modifications will be required to better optimisation of welding.Horizon Europe (UK participants are supported by UKRI [10040791] (University of Leeds
