This paper presents a recognition algorithm combining the vehicle detection and the color difference of RGB color space to recognize the brake-lights state of moving vehicles in order to achieve the intelligent-car’s rear-end collision warning about the vehicle in front of it. Firstly, we train and build AdaBoost cascade classifier by haar features samples and scaling sub-windows are used to de...

A 75-year-old male presented to the emergency department (ED) following a fall from his bicycle. The patient fell face-first onto the handlebars, with the brake handle impaling his left upper lip. Paramedics were able to detach the handle from the bicycle and transport him to the ED. He denied loss of consciousness, neck pain, dental pain, or other injuries. Examination revealed the brake handl...

A brake hardware-in-the-loop simulation (HILS) system for a railway vehicle is widely applied to estimate and validate braking performance in research studies and field tests. When we develop a simulation model for a full vehicle system, the characteristics of all components are generally properly simplified based on the understanding of each component's purpose and interaction with other compo...

During the braking action, the kinetic energy produced at the wheel is transformed into heat energy, which doesn’t dissipate fast enough into the air stream from the brake to the brake disk; as a result, the thermal conductivity plays a critical role in handling such heat generated. Thermal judder, which is a result of non-uniform contact cycles between the pad and the disk brake rotor, which i...

In this paper, the brake driving intention identification parameters based on the fuzzy controlare summarized and analyzed, the necessary parameters based on the fuzzy control of the brake driving intention recognition are found out, and I pointed out the commonly corrupt parameters, and through the relevant parameters ,I establish the corresponding driving intention model.

A cost effective, low maintenance generator brake is proposed using recent developments in thick film, metal oxide resistors. The brake has very low resistance, and virtually no inductance, allowing its use &ring a fault to slow a generator’s acceleration. Simulation results using the 39 Bus New England system show that placing brakes at each machine dramatically increases the global stability ...

In this paper, we consider the minimal period estimates for brake orbits of nonlinear symmetric Hamiltonian systems. We prove that if the Hamiltonian function H ∈ C(R,R) is super-quadratic and convex, for every number τ > 0, there exists at least one τ -periodic brake orbit (τ, x) with minimal period τ or τ/2 provided H(Nx) = H(x). §

The thermal balance analysis is a useful method to determine energy distribution and efficiency of internal combustion (IC) engines. In engines cooling concepts, estimation of heat transfer to brake power ratio, as one of the most significant performance characteristics, is highly demanded. In this paper, investigation of energy balance and derivation of specific heat rejection is carried out e...

AbstractStringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for the petro-diesel. The oxygenated fuel used is dibutyl ether(DBE). While injection pressure is 200 bar and injection timing is 20.5 0 BTDC we get higher brake thermal efficiency and lower brake specific fuel consumption for DBE10 compare to diesel.

there are several methods for analysing the behaviour of underground structures under different loading conditions. most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. on the other hand, for stability analysis and the designing of support systems, these methods consider segme...
