BACKGROUND The aim of this study was to evaluate the safety and efficacy of distal pancreatectomy with en bloc celiac axis resection (DP-CAR) for pancreatic body-tail cancer. MATERIAL AND METHODS The medical records of 12 patients who underwent DP-CAR for pancreatic body-tail cancer were retrospectively studied, together with a literature review of studies including at least 3 cases of DP-CAR...

In this paper, a method for reducing unspring mass as well as improving safety and ride properties of vehicles driven by in-wheel motors will be provided. To begin with, the advantages of vehicles armed with in-wheel motors will be described, after which some drawbacks of this idea will be studied. Then, to getting a better analysis, quarter car model will be studied in frequency domain. Gain o...

the six-degree equations of flight in their classic form do not provide a proper physical perception due to a number of interferences. nor do they render visible the important role of attack angles. in this study, attempts have been made to develop a complete set of 3d acceleration equations from the equations of normal and tangential acceleration αn=vωv, αt=v ̇. for this purpose, a coordinate s...

The presence of fast and slow modes in vehicle suspension systems, based on a half car model, is utilized in the design of active suspension control using singular perturbation theory. This strategy is based on the slow-fast control design. The suspension system performance is optimised with respect to ride comfort, road holding and suspension rattle space as expressed by the mean-square-values...

A robust decoupling control law was derived for active car steering under some mild assumptions. The control law simpliies the steering transfer function from the steering wheel input commanded by the driver to the lateral acceleration at the front axle. In this paper it will be shown that the decoupling is preserved even if nonlinear diierential equations are assumed as a tire model.

Following the political discussion of global warming and the political objective to support green mobility, in particular electric mobility, there is a substantial discussion whether or not electrical vehicles are dangerous for pedestrians based on their low noise level. This paper aims at answering the question regarding the specific injury risk resulting from electrical vehicles. The study is...

Current internal combustion engine technology for road vehicles allows us to meet the existing and planned future standards for emission. However, the motion of a moving vehicle used in real operating conditions is frequent changes of the values of power in the powertrain. The analysis of the results of the road test through a measurement of parameters of engine in a passenger car proves, that ...
