Attracting Students to Transportation Engineering

With a significant fraction of the nation's transportation workforce nearing retirement age, it is essential to attract new talent to transportation fields and to retain that talent. In addition, it is also important to attract a diverse wo...

Transportation Engineering Careers

Critical to building an American workforce with 21st century skills is the recruitment and graduation of students in science, technology, engineering, and mathematics fields. However, a nationwide lack of student interest and preparation in...

Transportation Engineering

Assessment of Introductory Transportation Engineering Course and General Transportation Engineering Curriculum

Transportation engineering is a critical subdiscipline of the civil engineering profession as indicated by its inclusion on the Fundamentals of Engineering Examination and overlap with other specialty areas of civil engineering and as recog...

Determination of optimum segmentation parameter values for extracting building from remote sensing images

Lately, with progresses in remote sensing information techniques and the growingly and unprecedented uses of its uses, remote sensing became a science that cannot be dispensed with in most fields and ground object extraction has turned out ...

Integrated modeling in the UK: Practical usability of integrated models

This short paper reviews the range of planning issues that are currently being addressed in Britain and considers how the nature of these issues and the ways in which choices are being assessed impact the modeling approaches being adopted, ...

The Effect of Mutual Coupling on a High Altitude Platform Diversity System Using Compact Antenna Arrays

We analyze the destructive effects of mutual coupling and spatial correlation between the separate antenna elements on a combined diversity system consisting of multiple HAPs (High-Altitude Platforms) employing various compact MIMO (Multipl...

The Impact of Phase-Locked Loop (PLL) Architecture on Sub-Synchronous Control Interactions (SSCI) for Direct-Driven Permanent Magnet Synchronous Generator (PMSG)-Based Type 4 Wind Farms

Electric vehicles (EVs) are a promising solution to reduce carbon dioxide (CO2) emissions, but this reduction depends on the fraction of renewable sources used to generate electricity. Wind energy is thus a vital candidate and has experienc...

Estimation for Two-Dimensional Nonsymmetric Coherently Distributed Source in L-Shaped Arrays

We explore the estimation of a two-dimensional (2D) nonsymmetric coherently distributed (CD) source using L-shaped arrays. Compared with a symmetric source, the modeling and estimation of a nonsymmetric source are more practical. A nonsymme...

Mat-heurística para recuperação de malhas aéreas considerando aeronaves e passageiros

O problema de recuperação da operação de companhia aérea impactada por uma interrupção envolve as malhas de aeronaves, de tripulantes e de passageiros. Modelos para resolvê-lo consideram uma ou mais dessas malhas, de forma integrada ou não....

Predicting Method for Lining External Water Pressure Reduction Coefficient Based on Equivalent Stable Drainage Volume Principle

［Objective］ By establishing a numerical seepage analysis model that aligns with real drainage systems and introducing the concept of a ′virtual permeability coefficient′ for secondary lining, the objective is to delve into the correlation b...

Low-carbon urban transportation: Optimizing mechanical systems for sustainable electric bus and BRT deployment in Kampala

Kampala faces increasing congestion, air pollution, and dependence on fossil fuels, driven by widespread reliance on diesel minibuses and motorcycle taxis. Existing models—KAMPALA-TIMES, KLAP-TIMES, and GKMA-TIMES–CGE—show strong potential ...

Control Strategies, Economic Benefits, and Challenges of Vehicle-to-Grid Applications: Recent Trends Research

With the rapid growth in the number of EVs, a huge number of EVs are connected to the power grid for charging, which places a great amount of pressure on the stable operation of the power grid. This paper focuses on the development of V2G a...

Effects of Titanate Coupling Agent on Engineering Properties of Asphalt Binders and Mixtures Incorporating LLDPE-CaCO3 Pellet

This study was initiated to evaluate the performance of asphalt binders and mixtures incorporating linear low-density polyethylene- calcium carbonate (LLDPE-CaCO3) pellet, either with or without titanate coupling agent. The detailed manufac...

Reputation assessment mechanism for carpooling applications based on clustering user travel preferences

One way to ensure sustainable and environmental friendly mobility is the use of less vehicles for carrying more passengers, and carpooling is a means to achieve this goal. One major concern in carpooling services is related to trust, as car...
