Reducing vehicle weight is critical to improving fuel economy and addressing range, performance, size, and cost challenges associated with fuel-cell and hybrid propulsion systems. This paper describes the design, fabrication, and assembly approach used for the carbon-fiber composite body structure in Hypercar, Inc.’s Revolution concept vehicle. The Revolution’s 187-kg body structure is 57% ligh...
BACKGROUND Heart failure with left ventricular (LV) hypertrophy is often associated with insulin resistance and inflammation. Recent studies have shown that dipeptidyl peptidase 4 (DPP4) inhibitors improve glucose metabolism and inflammatory status. We therefore evaluated whether vildagliptin, a DPP4 inhibitor, prevents LV hypertrophy and improves diastolic function in isoproterenol-treated rat...
This paper describes the fundamental motivation and ideas surrounding current developments in available energy-based methods for vehicle design, which are a class of methods allowing direct estimation of the total cost chargeable to each loss mechanism in any general vehicle design (land, sea, air, or space). It is shown that losses can be expressed in terms of chargeable fuel weight. These are...
In the field of motor vehicle recognition, use neural network models has become standard, and tuning hyperparameters loss functions been shown to be an effective way improve performance these models. However, when using classical convolutional architectures (e.g., ImageNet) training them on images with random labels, overparameterization problem can lead suboptimal results increased risk recogn...
Abstract We present a set of new instances the maximum weight independent problem. These are derived from real-world vehicle routing problem and challenging to solve in part because their large size. with up 881 thousand nodes 383 million edges.
