This paper presents an optimal control-based energy management strategy for a parallel hybrid electric vehicle (HEV). Not only does this try to minimize fuel consumption while maintaining the state of charge battery within reasonable bounds, it also seeks wear and extend its life. focuses on understanding control solution offered by Pontryagin's minimum principle (PMP) in context. Simulation-based results are presented analyzed, which show that algorithm is able reduce decreasing operating...
Energy-efficient metro operation has received increasing attention because of the energy cost and environmental concerns. This paper developed an integrated optimization model on train control timetable to minimize net consumption. The extents motoring braking as well configurations such headway interstation runtime are optimized consumption with consideration utilizing regenerative energy. An improved is proposed reduce traction by allowing coasting downhill slopes much possible. Variations...
Transport-energy transitions pose complex challenges that have been extensively studied in high-income countries response to national mandates for climate action.Low-and middle-income countries, however, low but rapidly growing motorisation rates and face very different adopting new technologies foster economic development ensure equitable access clean transportation.Here, we present a set of narrative scenarios the future Kenyan transport-energy system co-developed through engagement with...
This paper presents an optimal energy management strategy for a parallel hybrid electric vehicle (HEV) equipped with continuous variable transmission (CVT). Not only does this try to minimize fuel consumption while maintaining the state of charge (SOC) battery within prescribed limits, it also seeks capacity loss and extend its life by optimally controlling torque split as well CVT ratio. Different from traditional scenario, in which recuperated braking is free, regenerative has cost aging...
This paper presents an optimal control based charging strategy for plug-in hybrid electric vehicles (PHEVs) and battery (BEVs). work proposes a method to minimize capacity degradation incurred during by optimizing current profile. A semi-empirical aging model is adopted quantify the loss; generic control-oriented vehicle cabin thermal developed describe surroundings taking into account solar radiation. Optimal solution offered Pontryagin's Minimum Principle (PMP) presented. Simulation-based...
Modern trams, as a rapidly developed high-volume transport model, have strict requirements on schedule, because the delay will reduce attractiveness of public transportation to passengers. To improve punctuality and reliability, Transit Signal Priority (TSP) has been employed at intersections, which can extend or insert green phase trams. However, extending inserting for every tram might lead heavy delays crossing vehicles. address this problem, study an integrated optimization model...

Electric mobility transition has been gradually gaining momentum, driven by several considerations, including the urgency to combat climate change impacts attributed private transport based on internal combustion engine. The nature and of such a will inevitably vary across countries because differences in patterns preferences societies, as well policy landscape. In Sub-Saharan Africa, paratransit is one dominant forms transport. This motivates need assess its viability for electric...
Purpose Selective laser melting (SLM) enables the fabrication of lightweight and complex metallic structures. Support structures are required in SLM process to successfully produce parts. Supports typically lattice structures, which cost much time material manufacture. Besides, manufacturability these supports is undesirable, may impact quality parts or even fail process. The purpose this paper investigate efficiency mechanical properties advanced internal branch support for SLM....
Prioritizing traffic signals for trams crossing intersections without stops can increase the service punctuality and travel speed of trams, but it may also delays other vehicles at intersections. This paper presents a model on coordinated control among successive along tramline, taking into account driving characteristics vehicles. The objective is maximizing valid bandwidth vehicle green wave to reduce delays, while cross stops. Linear Interactive General Optimizer (LINGO) applied solve...
This paper presents an optimal control-based energy management strategy for a parallel hybrid electric vehicle (HEV). not only seeks to minimize fuel consumption while maintaining the state-of-charge of battery within reasonable bounds, but also wear and extend its life. multi-objective control problem is solved numerically using Pontryagin's Minimum Principle (PMP).
Passengers on metro platforms can board a train only when the has surplus capacity and dwell time is sufficient, while latter condition omitted in previous studies. Taking into account impacts of passengers boarding, this study develops model optimizing timetable to reduce passenger travel operating cost, through regulating trains' inter-station run-time, headway. The NSGA-II algorithm employed obtain near-optimal Pareto Frontier proposed model. To address insufficient scheduled timetable,...
This paper presents two optimal energy management strategies for a parallel hybrid electric vehicle (HEV) equipped with continuously variable transmission (CVT). The goal both is to try minimize fuel consumption while maintaining the state of charge (SOC) battery within prescribed limits, as well capacity loss and extend its life. first strategy, which referred sequential optimization, operates CVT along engine operating line (OOL) then uses dynamic programming determine torque split between...
The National Transit Database (NTD) includes comprehensive data on transit organization characteristics, vehicle fleet revenues and subsidies, operating maintenance costs, reliability inventory, services consumed supplied, safety security. Some of these have been used extensively to derive values for performance measures become the sole source standardized use by all constituencies U.S. industry. An important application NTD has in trend analysis, which requires multiple years data. However,...
The existing literature suggests that worker's cognitive and non-cognitive abilities have a significant impact on wages. However, presently there is little research in this area of China's labor force, due to scanty data. To end, Paper conducted CEES-based data research, which found that, the male, skilled workers greater their wages, as compared with those female, unskilled workers. OLS regression based Mincer Wage Equation wages generally larger than abilities. All positive wherein...
The vibrant signal of diesel engine is analyzed by the method bispectrum, and bispectral feature planes are searched along diagonal parallel lines at certain step in modulus field, mean breadth value calculated as which capable describing fault. support vector machines used to diagnose fault successfully importing features training samples. experiment results show that, noise can be eliminated bispectrum extracted effectively; perfectly described exist not only on but also field besides...
