Biologically inspired modeling of vehicle to vehicle communication for intelligent transportation systems applications
No full textIn this study we developed a macroscopic model for simulating the vehicle to vehicle communication process. Real-time information propagation via vehicle-to-vehicle communication is part of the Vehicle Infrastructure Integration (VII) initiative, aimed at
improving the traffic conditions on existing roadways. In VII, Vehicles communicate among themselves using wireless technology. Each vehicle broadcasts any available information regarding the roadway (which might include time taken to travel a small stretch, any hazardous conditions, incidents etc) and other vehicles upstream, which might not be aware of the conditions ahead, receive the information. In this thesis, a
fraction of the vehicles traveling on the network are assumed to be equipped with the wireless technology and have the ability to communicate. These are called the “instrumented” vehicles. The proposed model is based on the Susceptible – Infected –Removed (SIR) model that is used to model the spread of epidemics in a region. We call the vehicles that have received a signal from another vehicle as ‘infected vehicles’, and
those instrumented vehicles that have not received a wireless message are called ‘susceptible vehicles’. The present model predicts the number of infected vehicles present on the roadway at every instant of time. The model is developed for a variety of traffic conditions including different volumes, speed limits and number of lanes. Finally, it is validated using simulation results obtained from Paramics, a microscopic traffic simulation software. Various observations related to the process of vehicle to vehicle communication were also made.M.S.Includes bibliographical referencesby Teja Indrakant

Synthesis of Carboxamide and Sulfonyl Carboxamide Linked Azoles Under Green Conditions
No full textDirect coupling of heteroaldehydes with heteroaryl amines/sulfonylamines is performed under green conditions using PEG-400 in the presence of oxidant CCl3CN/H2O2. The presence of electron-withdrawing substituents on heteroaldehydes increased the yield. Further heteroaryl amines favor the reaction when compared with heteroaryl sulfonylamines. © 2020 Author(s).One of the authors G.

Vortices in Hyperbolic Funnels as Aeration Systems: A Numerical Study
No full textExperiments to characterise vortices in hyperbolic shaped funnels are being conducted at the Water Application Centre (WAC) in Wetsus. These have demonstrated their higher gas transfer rates in comparison to the conventional aeration systems presently in use. Depending on the imposed flow conditions, different regimes of vortices are formed, among which the Twisted vortical structure is observed to have the highest gas dissolution rates. This has probed several questions on the physical mechanisms responsible on both micro-and macroscopic scales. The present research aims to numerically analyse the flow field organisation in these vortices to reason the observed high gas transfer rates using Computational Fluid Dynamics (CFD). Transient simulations were performed on a three-dimensional radially structured hexahedral mesh. Multi-phase modelling was done using the Euler-Euler approach-based Volume-of-Fluid (VOF) method, while the turbulent flow was modelled using Shear Stress Transport (SST) based on k - ω equations with curvature correction. The choice of boundary conditions and their location is crucial for forming a stable vortex in the hyperbolic funnels. The position of the air-water interface from experimental results was used to validate the obtained numerical results. Two regimes of the vortex, namely the Twisted and Straight vortical structures, were evaluated for their gas transfer capabilities in terms of Hydraulic Retention Time (HRT), interfacial area and mixing in the bulk. Instabilities arise in the secondary flow field of these vortical structures analogous to the Taylor-vortices that develop in the well known Taylor-Couette flow systems. In hyperbolic funnels, these instabilities aid in advecting the bulk of liquid to the air-water interfacial region and also enhance mixing within the bulk of water. The former enhances the gas transfer rates while the latter promotes uniform mixing. The strength of these instabilities is qualitatively analysed in terms of average vorticity per unit mass of water. This is found to be higher in the Twisted regime in comparison to other regimes. This is augmented by high air-water interfacial area making this regime possess superior gas transfer rates. Although the gas transfer rates are high, water exiting the funnel is undersaturated at the given operating conditions. In order to further enhance the amount of gas dissolved few possibilities are qualitatively discussed at the end of this study. Mechanical Engineering | Energy and Process Technolog

Study of Phospholipid/Graphene interfaces and the effect of substrate curvature on lipid morphology and dynamics.
No full textPhospholipids are an important class of lipids which are widely used as model platforms to study biological processes and interactions. They have been known to form stable interfaces with solid substrates like graphene, and these interfaces have potential applications in bio-sensing and targeted drug-delivery. In this paper, we perform molecular dynamics simulations of graphene supported lipid monolayers to characterize lipid properties in such interfaces. We observed substantial differences in lipid properties like tail order-parameter, density profile, diffusion rate, etc., between lipids in a supported monolayer and free-standing bilayer. Further, we studied these interfaces on sinusoidally deformed graphene substrates to understand the effect of curvature on the supported lipids. Here, we observed that the nature of substrate curvature—concave, convex or flat—can affect the lipid/substrate adhesion strength as well as induce structural and dynamical changes in the adsorbed lipid monolayer. Together, these results help characterize the properties of lipid/graphene interfaces, as well as understand the effect of substrate curvature on these interfaces, which can enable tuning of lipid properties for various sensor device and drug delivery applications.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-08-01The student, Mohan Teja Dronadula, accepted the attached license on 2021-07-21 at 14:29.The student, Mohan Teja Dronadula, submitted this Thesis for approval on 2021-07-21 at 14:57.This Thesis was approved for publication on 2021-07-22 at 16:43.DSpace SAF Submission Ingestion Package generated from Vireo submission #17054 on 2022-01-12 at 13:05:30Made available in DSpace on 2022-01-12T22:56:15Z (GMT).

Comparison of teaching social studies with and without use of interactive whiteboard
No full textIn thesis we compared the results of teaching social studies with and without the use of interactive whiteboards. In the theoretical part we present information and communication technology. Our emphasis was placed on the use of interactive whiteboard and gadgets that are affiliated with its use. Some teachers that are already using interactive whiteboard have come to know the advantages and disadvantages of working with the interactive whiteboard. Their findings are also presented in this thesis. The biggest advantages of using the interactive whiteboards are different way of presentation of the subject and activities that we can carry out.
In empirical part we present our study. Our participants were two teachers and 32 pupils from the third grade. We conducted the experiment at the subject of environmental studies. We tried to answered on two questions – will the final knowledge of pupils be the same, with or without the use of interactive whiteboards and in which way of learning will pupils be more active (with or without the use of interactive whiteboard)?
Based on our results we have come to the conclusion that the use of interactive whiteboards does not affect the acquisition of knowledge. And we have also discovered that the activity of pupils between both groups did not vary
