ER measurement was first introduced to soil science in the 1970s to determine soil salinity due to the fact that soil solution extraction in the laboratory is time-consuming and cost intensive and also due to high local-scale variability associated with small volume soil core samples.Rhoades (197...
We study the optimization of large-scale, real-time ridesharing systems and propose a modular design methodology, Component Algorithms for Ridesharing (CAR). We evaluate a diverse set of CARs (14 in total), focusing on the key algorithmic components of ridesharing. We take a multi-objective appr...
In our study, we utilize large-scale real-world data to assess the impact of vehicle electrification on air quality, focusing particularly on China’s super-tier-1 cities, which predominantly rely on coal-based power generation. We analyze the relationship between BEV usage patterns—namely mileage...
body underneath. We decided to keep the photovoltaic area as large as possible for maximum efficiency and range and this is also the main reason for choosing a flat solar panel surface. We deliberately created Sunnyclist to be a three wheeler for lower friction, weight, complexity and cost. ...

1. The transportation sector is responsible for 30% of the U.S. total greenhouse gas (GHG) emissions and light duty vehicles (LDVs) account for close to 60% of the transport sector GHG emissions (U...
Imagine what that 8bil-to-1 weight ratio must cost? For a beach landing, the transition of infantry from the well deck to the shore and inland must be via a single delivery system, not two. And it must carry a sizeable number of Marines, not half a rifle squad. Future, compromised,...
While fully dedicated factories for the large-scale production of EVs have been opened in WE (e.g., VW's factories at Zwickau and Emden, Tesla's fac‑ tory near Berlin) or are being planned (e.g., VW's Trinity factory near Wolfsburg), EE factories have so far employed the strategy...
However, changes in viewpoint, and changes in scale make the object detection task in drones more challenging than traditional object detection. In a traffic surveillance scenario, drones record traffic from a bird's eye view. The advantage of this to 100 m in height to record vehicle traffic...
In the design of automobiles, greater fuel efficiency and improved running performance are aimed for with the reduction of body weight and the computerization of the control systems. Also, development of electric and hybrid cars are taking place at a rapid pace, with the aim of breaking dependenc...
