Overloaded vehicles is one of the main problemsthat cause premature failure in road infrastructure. This paper presents an analysis overloaded vehicles'effect on flexible pavement based historical weigh-in-motion data. Thisarticle highlights potential use (WIM) data design by addressing overload, percentage overloading, and axle load distribution. The can reach more than 80% total number trucks...
We extend three types of overloaded CDMA systems, by displacing in time the binary signature sequences of these systems: (1) random spreading (PN), (2) multiple-OCDMA (MO), and (3) PN/OCDMA (PN/O). For each of these systems, we determine the time shifts that minimize the overall multiuser interference power. The achievable channel load with coded and uncoded data is evaluated for the convention...
In overloaded CDMA systems the high correlation among users’ signatures determines an overall performace that can be quite poor even for the optimal ML receiver. The geometric properties of signatures affect users’ separability, a condition that is necessary for achieving asymptotic efficiency. In this paper we establish gaussian separability conditions and propose an algorithm for the design o...
Orthogonal drawings are widely used for graph visualization due to their high clarity and ease of representation. But when it comes to highdegree and massive graphs, even orthogonal drawings have difficulties producing a clean and simple visualization. In this paper we present a technique called Overloaded Orthogonal Drawing that greatly improves the readability by proposing a new vertex placem...
The matricellular protein thrombospondin (TSP) 1 is induced after tissue injury and may regulate reparative responses by activating transforming growth factor-β, by suppressing angiogenesis and by modulating inflammation and matrix metabolism. We hypothesized that endogenous TSP-1 may be involved in the pathogenesis of cardiac remodeling in the pressure-overloaded heart. Myocardial TSP-1 expres...
Chemokines have been suggested to play a role during development of left ventricular failure, but little is known about their role during right ventricular (RV) remodeling and dysfunction. We have previously shown that the chemokine (C-X-C motif) ligand 13 (CXCL13) regulates small leucine-rich proteoglycans (SLRPs). We hypothesized that chemokines are upregulated in the pressure-overloaded RV, ...
Overexpression of sarcolipin (SLN), a regulator of sarco(endo)plasmic reticulum Ca2+-ATPases (SERCAs), stimulates calcineurin signaling to enhance skeletal muscle oxidative capacity. Some studies have shown that calcineurin may also control skeletal muscle mass and remodeling in response to functional overload and unload stimuli by increasing myofiber size and the proportion of slow fibers. To ...
