Effects of longitudinal bending stiffness and midsole foam on running energetics

Advanced footwear technology has become commonplace in the competitive running world. However, a systematic exploration of the effects of each of the primary components has not yet been presented. Our goal was to quantify running economy and step parameters in four different shoe conditions: PEBA shoes with plate, PEBA shoes without plate, EVA shoes with plate and EVA shoes without plate. Participants ran at 14 km/h (n = 8 males) or 12 km/h (n = 6 females) on a treadmill. The shoe order was randomly assigned for the four shoe conditions, where the participants wore each shoe twice in a mirrored order. There was a significant reduction in metabolic power (1.0%) associated with the presence of a plate, as well as a similar reduction based on foam type (1.0%). However, there was no significant interaction between presence of plate and foam type. Adding a plate significantly reduced metabolic power for EVA by 1.3% but not for PEBA. PEBA foam significantly reduced metabolic power by 1.3% in shoes without a plate, but not for the shoes with a plate. Step frequency and contact time were similar between shoes and not correlated to running economy improvements. Starting from a baseline condition with traditional foam without a plate, either adding a plate or using PEBA foam improved running economy with a similar amount (1.3%). Adding the alternate second feature non-significantly improved running economy with an additional 0.6%. The benefit of both technologies combined (1.9%) was smaller than the sum of its parts (1.3% each).

Innovative Approaches to Beam Forming Antenna Array Systems with Adaptive Partial Update NLMS Algorithms

Improvements in interference cancellation, energy economy, spectrum efficiency, and system security are among the most pressing needs for today's wireless networks. One effective technique for this is the use of a Beamforming Array Antennas (BAA). However, the complexity of the Beamforming (BF) network, the long convergence time, and the large number of adjustable weight coefficients, all work against full band BAA. The key innovation and contribution of this research was to use Partial Update (PU) instead of full band adaptive algorithms, as no previous attempt had been made to do so. A subset of the array's elements, rather than all of them, will be connected to by PU methods. This allows the system to reduce the number of active antennas across all cells while maintaining high efficiency, and low cost. In this research, a new architectural model was proposed that makes use of PU adaptive algorithms, to reduce the required number of phase shifters (PSs), and hence base station antennas. For the most part, we will be discussing PU Normalized Least Mean Square (PU NLMS) algorithms like M-max NLMS, Periodic-NLMS, and Stochastic-NLMS. Using a Uniform Linear Array (ULA) Antennas in a simulation environment, we find that the, in terms of Mean Square Error (MSE), convergence rate, and steady-state error, it is evident that all PU NLMS algorithms (with the exception of Periodic-NLMS) had performed close, and approximately equivalent performance to the full band NLMS algorithms. In other hands, these PU algorithms maintain the radiation pattern with as little change from the original (distortion-free) as possible and symmetrical of the array, while. fewer elements are needed to produce the same amount of radiation. Reducing the number of required coefficients N to M (M = 5; M: Number of coefficients to be update per iteration) compared to the full update method (N = 8), to obtain the Reduction ratio 38%.

The local wisdom of coastal communities is one of the potential for supporting survival amidst limited capital and fishing equipment. Local wisdom, one of which is from natural resources, has the potential to support the improvement of the fishermen's economy. Utilizing local resources by managing fish products into processed products is one of the fishing communities' efforts to develop local potential based on local wisdom. Apart from natural potential in socio-cultural terms, namely the sea picking tradition and knowledge of the fish season calendar, it is also a form of local wisdom from the fishermen of the Pesinggahan Traditional Village which is used to maximize the productivity of marine products. These external factors also encourage the development and production of local products, especially the management of processing marine products into processed products from fishing families. Management developed through efforts to form MSMEs using SWOT analysis to develop local products. These processed products include mackerel fish crackers, smoked fish, fish paste, and dried fish. The results of this research show that the local productivity of the Pesinggahan Village fishing community is maintained because the management is carried out using an integrated work system even though it is very simple and traditional. The efforts made in this research are improvements to build MSMEs through the participation of fishing families which are currently maintained so that local products become regional characteristics. Integrated marine product management can improve the economy of fishermen in meeting their living needs.

Modelling the impact of reducing lubricant viscosity on a conventional passenger car fuel economy and wear protection

This study explores how reducing lubricant viscosity affects fuel economy in passenger cars through experimental characterization and semi-predictive modelling. Thus, three engine oils (0W-20, 5W-30, and 5W-40) were tested for their rheological and tribological properties. Data were introduced into a detailed GT-Suite model of a turbocharged gasoline SUV. Simulations over six different driving cycles, including European homologation and real-driving conditions, used a fast-running model (FRM) to assess engine friction and wear protection. Results showed that lower viscosity oils, especially 0W-20, significantly reduced frictional losses, enhancing fuel economy. However, lower viscosity also increased contact friction under high power demand, raising durability concerns. A comprehensive evaluation of lubricants performance, offering insights into the trade-offs between fuel economy improvements and potential durability risks.

Province-Level Decarbonization Potentials for China's Road Transportation Sector.

Decarbonizing road transportation is an important task in achieving China's climate goals. Illustrating the mitigation potentials of announced policies and identifying additional strategies for various vehicle fleets are fundamental in optimizing future control pathways. Herein, we developed a comprehensive analysis of carbon dioxide (CO2) emissions from on-road vehicles as well as their mitigation potentials based on real-world databases and up-to-date policy scenarios. Total CO2 emissions of China's road transportation are estimated to be 1102 million tons (Mt) in 2022 and will continue to increase if future strategies are implemented as usual. Under current development trend and announced policy controls (i.e., integrated scenario), annual CO2 emissions are estimated to peak at 1235 Mt in 2025 and then decline to approximately 200 Mt around 2050. The scenario analysis indicates that electrification of passenger vehicles emerges as the most imperative decarbonization strategy for achieving carbon peak before 2030. Additionally, fuel economy improvement of conventional vehicles is identified to be effective for CO2 emission reduction for trucks until 2035 while new energy vehicle promotion shows great mitigation potentials in the long term. This study provides insight into heterogeneous low-carbon transportation transition strategies and valuable support for achieving China's dual-carbon goals.

Political economy and slum improvement: a study on longitudinal data of Kolkata slums

This study investigates the political economy of slums to understand the role of political competition, electoral power, and political alignment in service delivery. The paper examines whether political competition is likely to improve housing and basic services in slums. It is based on surveys of slum dwellers in 2012 and 2021–22 in Kolkata, India. The results suggest that slum improvement may lead to slum eviction in the future. The political alignment and their electoral power of elected members influence housing and basic services. Ward level high political competition and fragmentation will degrade service in a slum if the incumbent administration and politician fail to showcase their credibility through overall long-term improvement of the service across all the slums. Housing and some services were found to better in slums facing high political competition and fragmentation. For an inclusive slum improvement, government should plan with the community and engage the market rather than depend on market-led or unplanned government initiatives.

Research on combustion cycle-by-cycle variations under high load in SACI mode and application potential of i-EGR coupling air dilution when fueled with methanol and gasoline

Spark assist compression ignition (SACI) is a efficient combustion mode but roughness combustion under high load limits its application. This test analyzed the combustion parameters variation coefficient and quantified the correlation between combustion parameters with spark ignition ratio under high load SACI mode for engine fueled with methanol and gasoline, further studied the potential of i-EGR combining air dilution on improving combustion performance. Results showed that fueled with methanol can reduce in-cylinder pressure and pressure rise rate, and relieve the combustion roughness. However, compared with gasoline engine, the combustion parameters was more sensitive to ignition timing and i-EGR rate, especially for combustion phase parameters like ignition delay, combustion center and so on. Introducing small amount of high-temperature exhaust gas into cylinder will induce rougher combustion, but cylinder pressure significantly reduced and combustion phase parameters fluctuated with i-EGR rate increasing. Under high i-EGR rate, methanol as an oxygenated fuel was more beneficial to maintain stable combustion. I-EGR coupling air dilution can significantly improve the economic performance under high load SACI mode, fuel economy improvements of up to about 17.4% and 19% compared to the origin point when fueled with gasoline and methanol. EGR combining air dilution can simultaneously improve BSNOX, BSTHC, and BSCO emissions.

The Impact of the Oil Industry on the Economic Development of Nigeria

The study examined the impact of the oil industry on the economic development of Nigeria. The Nigerian petroleum industry dominates the Nigerian economy in terms of profits and revenue. According to the recent Petroleum Export Organization (OPEC) report, Nigeria currently ranks as the world's tenth-largest crude oil reserves and also the world's fifteenth crude oil producer. According to national statistics, the industry generates for the country more than 95% of the country's external revenue and about 80% of government revenue. Secondary data collected on the economic variable used in the study comes from the World Bank, worldometer, and the International Monetary Fund, Statistical Review of World Energy, Central Bank of Nigeria (CBN) Statistical Bulletin, CEICDATA (Organization of the Petroleum Exporting Countries) from 1990 to 2016. An augmented Dickey-Fuller unit root test, and autoregressive distributive lag (ARDL) method, and ARDL related to the test co-integration with various other diagnostic techniques were used for the study. The result reveals that oil production contributed to economic development, but the consumption and export of crude oil did not contribute to the improvement of the Nigerian economy. The study concluded that the government should implement policies that would encourage the private sector to actively participate in the crude oil sector and sectors of the economy. In addition, the government should use the revenue generated from oil to invest in other national sectors such as agriculture and manufacturing to expand the revenue stream of the economy

Research on the Joint Supervision System of Finance, Audit and Inspection in Universities

With the continuous improvement of the global economy and information technology, the education sector has entered an unprecedented new stage of development. As an important component of the education sector, the scale of universities are expanding year by year. With the continuous development of universities, the multi campus education model has quietly emerged, and research projects are increasing day by day. The diversification of research funding channels has put forward higher requirements for government supervision of universities, and relying solely on single department supervision is no longer applicable.
