Experimental investigation on sol–gel transition of asphaltSpringer Science and Business Media LLC - Tập 3 Số 1 - Trang 131-139 - 2011
Padmarekha, A., Krishnan, J. Murali
This article is concerned about the sol–gel transition of asphalt by dynamic mechanical analysis. By sol–gel transition of asphalt, we mean here the transition from viscoelastic fluid to viscoelastic solid as the temperature is varied. In this investigation two types of asphalt of the same specification grade but manufactured by different process (blending and air blowing) were tested at unaged, s...... hiện toàn bộ
The effect of chemical reaction on thermo-solutal magneto-convection under non-equilibrium temperature conditionsSpringer Science and Business Media LLC - - 2024
Monal Bharty, A. K. Srivastava, Hrishikesh Mahato
The onset of convection in a porous medium saturated by the Oldroyd-type viscoelastic fluid, heated and salted from below, is investigated by incorporating the effects of chemical reactions on boundaries and externally imposed magnetic fields with non-equilibrium temperature conditions. The normal mode technique is used to perform linear stability analysis. The whole study is divided into two part...... hiện toàn bộ
A review of the mathematical models for traffic flowSpringer Science and Business Media LLC - Tập 1 - Trang 53-68 - 2009
V. Tyagi, S. Darbha, K. R. Rajagopal
In this paper, we critically review mathematical models for the flow of traffic that treat traffic as a continuum and provide a discussion of their shortcomings. We also review a spatially discrete traffic flow model that does not suffer from such shortcomings and provide recently collected, corroborating data for a trip-time estimation scheme based on the spatially discrete model.
Graphical dynamical systems and their applications to bio-social systemsSpringer Science and Business Media LLC - Tập 11 - Trang 153-171 - 2018
Abhijin Adiga, Chris J. Kuhlman, Madhav V. Marathe, Henning S. Mortveit, S. S. Ravi, Anil Vullikanti
In this review paper, we discuss graphical dynamical systems (GDSs)
and their applications to biological and social systems (bio-social systems). Traditionally, differential equation-based models have been central in modeling bio-social systems. GDSs provide an alternate modeling framework. This framework explicitly represents individual components of the system and captures the interactions amon...... hiện toàn bộ
Modeling chloride ingress in concrete with thermodynamically calculated chemical bindingSpringer Science and Business Media LLC - Tập 9 - Trang 97-108 - 2017
Vahid Jafari Azad, O. Burkan Isgor
An alternative approach is developed to incorporate chloride binding/release processes during modeling of ingress of external chlorides in concrete through the use of thermodynamic modeling of chemical reactions. Transport of chloride in concrete is modeled through transient finite element analysis. At each time marching step, the chloride binding/release reactions are modeled using thermodynamic ...... hiện toàn bộ
A review of cyclic simple shear test on soils: challenges and new solutionsSpringer Science and Business Media LLC - Tập 14 - Trang 49-59 - 2022
B. R. Madhusudhan
Conventional and earlier versions of the cyclic simple shear tests employed specimens confined within stacked rings or wire reinforced membranes or rigid boundary platens. A new type of cyclic simple shear where the specimens are tested within the confines of a flexible membrane as in the case of the conventional cyclic triaxial testing system is presented and described. The principles, the advant...... hiện toàn bộ
Dynamic response of polysilicon microcantilevers to enzymatic hydrolysis of ureaSpringer Science and Business Media LLC - Tập 2 - Trang 17-22 - 2011
Renny Edwin Fernandez, Enakshi Bhattacharya, Anju Chadha
Micromolar levels of urea [1–20 mM] on surface micromachined polysilicon cantilever beams immobilized with the enzyme urease was studied. Urea hydrolyses to ammonia and carbon dioxide which are volatile in nature. Monitoring the change in resonance frequency of a urease immobilized cantilever beam during the course of urea hydrolysis, mediated by the immobilized enzyme can give us information on t...... hiện toàn bộ
In-network estimation of frequency momentsSpringer Science and Business Media LLC - Tập 5 - Trang 76-84 - 2013
Pooja Vyavahare, Nutan Limaye, D. Manjunath
We consider the problem of estimating functions of distributed data using a distributed algorithm over a network. The extant literature on computing functions in distributed networks such as wired and wireless sensor networks and peer-to-peer networks deals with computing linear functions of the distributed data when the alphabet size of the data values is small, O(1). We describe a distributed ra...... hiện toàn bộ
