Dynamic traffic management strategies (e.g. perimeter control, gating) that benefit from macroscopic fundamental diagram (MFD) dynamics provided promising results regarding their effects on network capacity and performance. However, this raises the question of route choice behavior in case of heterogeneous urban networks, where different parts are modeled with separate MFD functions. In this st...
High frequency force balance ~HFFB! measurements have recently been utilized to identify the distribution of spatiotemporally varying fluctuating wind loads on buildings. These developments, predicated on their ability to compute any response component of interest, based on actual building characteristics, attempt to offer a framework that eliminates the need for mode shape corrections generall...
12 In vibration-based structural health monitoring, changes in the natural frequency of a structure 13 are used to identify changes in the structural conditions due to damage and deterioration. 14 However, natural frequency values also vary with changes in environmental factors such as 15 temperature and wind. Therefore, it is important to differentiate between the effects due to 16 environment...
Modelling Crack Propagation in Aluminium-Alloys 2524-T3 and 7050-T7452 Subjected to Fatigue Loading at Low Temperature M. D. Liu and J. J. Xiong * School of Transportation Science and Engineering, Beihang University, Beijing 100191, China; [email protected] * Correspondence: [email protected] Abstract: This paper seeks to model the crack propagation in of AAs (aluminum-alloys) 2524-T3 and 705...
BACKGROUND It has been demonstrated that frequency modulation of loading influences cellular response and metabolism in 3D tissues such as cartilage, bone and intervertebral disc. However, the mechano-sensitivity of cells in linear tissues such as tendons or ligaments might be more sensitive to changes in strain amplitude than frequency. Here, we hypothesized that tenocytes in situ are mechano-...
This is a dummy paper to test the loading of heterogenous papers into the citeseer database. It was generated using the “SCIgenAn Automatic CS Paper Generator” [12]. I then inserted random references through out the paper pointing to papers randomly downloaded from the dtic web site to test. Any text contained in this pseudo paper is completely artificial.
Current therapeutic angiogenesis strategies are focused on the development of biologically responsive scaffolds that can deliver multiple angiogenic cytokines and/or cells in ischemic regions. Herein, we report on a novel electrospinning approach to fabricate cytokine-containing nanofibrous scaffolds with tunable architecture to promote angiogenesis. Fiber diameter and uniformity were controlle...
BACKGROUND Reset osmostat (RO) occurs in 36% of patients with syndrome of inappropriate antidiuretic hormone secretion (SIADH) and is not often considered when evaluating hyponatremic patients. Patients with RO are not usually treated, but recent awareness that symptoms are associated with mild hyponatremia creates a therapeutic dilemma. We encountered patients with hyponatremia, hypouricemia a...
