Road transport is a scenario for the use of fossil fuels to large extent, and process electrification can slow down this fuels. This study analyzes annual emissions nitrogen oxides (NOX) carbon dioxide (CO2) from heavy-duty diesel vehicles (HDDVs) feasibility in Beijing based on on-board diagnostics (OBD) remote monitoring data more than 9000 HDDVs. The NOX CO2 13 industry types were 44,980.9 6...

A hybrid micro air/ground vehicle has been developed and is specifically tailored to explore interior spaces with complex terrain. The vehicle, called the hopping rotochute, maneuvers through intricate environments by hopping over or through impeding obstacles. A small coaxial rotor system provides the necessary lift while a moveable internal mass allows directional control. In addition, the lo...

Intelligent vehicle platoon driving is a process of flexible control based on the coordination between vehicle and highway in intelligent vehicle-highway system. It can improve the velocities and reduce the spacing between vehicles in the platoon, thus, to improve road capacity and road safety. It is the most important for developing intelligent vehicle-highway system to construct intelligent v...

Mathematical modeling of supply chain operations has proven to be one of the most complex tasks in the field of operations management and operations research. Despite the abundance of several modeling proposals in the literature; for vast majority of them, no effective universal application is conceived. This issue renders the proposed mathematical models inapplicable due largely to the fact th...

BACKGROUND Although the capacity of exogenous PTH1-34 to enhance the rate of bone repair is well established in animal models, our understanding of the mechanism(s) whereby PTH induces an anabolic response during skeletal repair remains limited. Furthermore it is unknown whether endogenous PTH is required for fracture healing and how the absence of endogenous PTH would influence the fracture-he...

Along a transit line, vehicle traffic and passenger traffic are jointly subject to variability in travel time and vehicle load hence crowding. The paper provides a stochastic model of passenger physical time and generalized time, including waiting on platform and in-vehicle run time from access to egress station. Five sources of variability are addressed: (i) vehicle headway which can vary betw...

In this paper we model and solve the multi-depot fleet size and mix vehicle routing problem (MDFSMVRP). This problem extends the multi-depot vehicle routing problem and the fleet size and mix vehicle routing problem, two logistics problems that have been extensively studied for many decades. This difficult transportation problem combines complex assignment and routing decisions under the object...
