Abstract:
The power take-off (PTO) damping mechanism is very important to the motion and power conversion for the wave energy converters. Based upon the potential flow theory, the series expression with unknown Fourier coefficients of velocity potential function of the basin where the cylindrical floating buoy is located is obtained by using the eigenfunction expansion method. According to the characteristics of the PTO damper, the motion and wave energy conversion characteristics of the float under the linear and non-linear PTO damping are studied, respectively, and the over-damping problem under the l

Abstract:
The Power Take-Off (PTO) system is the key component of a Wave Energy Converter (WEC) that distinguishes it from a simple floating body because the uptake of the energy by the PTO system modifies the wave field surrounding the WEC. Consequently, the choice of a proper PTO model of a WEC is a key factor in the accuracy of a numerical model that serves to validate the economic impact of a wave energy project. Simultaneously, the given numerical model needs to simulate many WEC units operating in close proximity in a WEC farm, as such conglomerations are seen by the wave energy industry as the pa

Abstract:
The AQWA software is often used to perform hydrodynamic analysis, and it is highly convenient for performing frequency domain simulations of Pelamis-like wave energy converters. However, hydraulic power take-off (PTO) must be simplified to a linear damping model or a Coulomb torque model when performing a time domain simulation. Although these simulation methods can reduce the computational complexity, they may not accurately reflect the energy capture characteristics of the hydraulic PTO. By analyzing system factors such as the flow and pressure of each branch of the hydraulic PTO, the output

In particular, the 540E PTO application greatly reduces fuel consumption for unit work. The best results in terms of hourly fuel consumption were achieved in 540E PTO application and V1 working speed.

Combined loading of engine power significantly reduces driving force as well as drawbar pull. In general, any change in power distribution will affect power balance and overall efficiency.

One of the primary challenges for wave energy converter (WEC) systems is the fluctuating nature of wave resources, which require the WEC components to be designed to handle loads (i.e., torques, forces, and powers) that are many times greater than the average load. This approach requires a much greater power take-off (PTO) capacity than the average power output and indicates a higher cost for the PTO. Moreover, additional design requirements, such as battery storage, are needed, particularly for practical electrical grid connection, and can be a problem for sensitive equipment (e.g., radar, co

Abstract:
Marine waves have the potential of playing a significant role in future energy production. Most converter prototypes utilise a hydrostatic transmission or Power-Take Off (PTO) to convert the mechanical motion of an oscillating body to generate electrical power. A test rig has been installed at the Institute for Fluid Power Drives and Controls (IFAS) together with Aquamarine Power and Bosch Rexroth. Currently a new PTO is tested with this test rig. This new PTO is called WavePOD and is intended to become an industry wide standard by providing flexibility to suit a range of different wave energy

Abstract While the field of wave energy has been the subject of numerical simulation, scale model testing, and precommercial project testing for decades, wave energy technologies remain in the early stages of development and must continue to prove themselves as a promising modern renewable energy field. One of the difficulties that wave energy systems have been struggling to overcome is the design of highly efficient energy conversion systems that can convert the mechanical power derived from the oscillation of wave-activated bodies into another useful product. Often the power take-off (PTO) i

Abstract:
Marine hydrokinetic devices are becoming a popular method for generating marine renewable energy worldwide. These devices generate electricity by converting the kinetic energy of moving water, wave motion or currents, into electrical energy through the use of a Power-Take-Off (PTO) system. Most PTO systems incorporate a mechanical or hydraulic drive train, power generator and electric control/conditioning system to deliver the generated electric power to the grid at the required state. Like wind turbine applications, the PTO system must be designed for high reliability, good efficiency, long s

Abstract:
In 2024, Zambia experienced the driest agricultural season in over 40 years, with significant crop losses, increased livestock deaths and, consequently, worsening poverty. Over 9 million people in 84 out of 116 districts were affected. Rising inflation impeded access to food for vulnerable households Being dependent on hydropower, the drought resulted in an enormous power deficit. In 2024 and early 2025 Zambia experienced power cuts of 21 hours a day, disproportionately affecting small and medium-sized enterprises that cannot afford solar power or generators.

This paper studies concentration and market power in Chile and Colombia and the role that globalization and automation have had in shaping these two phenomena. Using panels of firm surveys, we compute firm-level markups and industry-level concentration measures. Applying a difference in differences methodology that relies on variation across industries in exposure to robotization technology, import competition from China and tariff declines in US markets due to the signature of free trade agreements, we study the causal effects of these shocks on market power and concentration.

Abstract:
Changes in brand ownership resulting from cross-border mergers and acquisitions impact competition and consumer welfare. Foreign acquisitions of local brands often lead to an increase in cost or a decline in appeal for the acquired brand, with limited gains in efficiencies. However, the accompanying rise in market power has translated into higher profits for the majority of brand-acquiring firms. Pro-competitive policies in the United States and European Union that required divestitures in the beer industry as a condition for merger approval led to significant consumer savings.

Abstract:
Federalism settles decision-making power to state levels close to the citizens. This political decentralization should enable political output being as responsive and corresponding as possible to the diverse demands and needs, thus, resulting in politically happy citizens. As such, federalism and decentralization may represent a polity of good governance. Based on the theoretical literature and previous empirical studies the paper undertakes a large N, cross-section analysis of the relationship between federalism and political satisfaction. The empirical result shows that federalism as well as

Research about trade liberalization's impact on markups has focused on manufacturing due to data availability considerations. How do these effects vary across sectors? Which industries become more and less competitive as trade barriers are eliminated? We leverage firm-level tax records from the universe of formal-sector businesses in Costa Rica with the 2009 trade liberalization as a natural experiment to evaluate its industry-specific effects on markups across all industries. We find negative effects on markups in agriculture, mining, electricity, water supply, and business services. Alternat

This paper uses standard fiscal incidence analysis to study how much income redistribution and poverty reduction are accomplished through the fiscal system in eighteen Latin American and Caribbean (LAC) countries. We show there is considerable heterogeneity in the income inequality and poverty-reducing power of LAC fiscal systems. While all LAC fiscal systems reduce income inequality, fiscal systems in nine LAC countries are poverty-increasing, and this startling characteristic has not improved over time. When analyzing specific fiscal elements, we find that direct taxes, direct transfers, and

The 2024 European Parliament (EP) elections have produced tectonic shifts in the Hungarian political landscape. While the populist governing party, Fidesz, secured first place in the elections, it lost two seats in the EP, and a new political force emerged that has reshuffled the power balance in Hungary’s opposition. Additionally, Prime Minister Viktor Orbán and his party, along with the pro-government media and social media outlets, spent huge amounts to deliver the government’s campaign messages, and the party reportedly broke mobilization records before the election.
