Towards Healthy Communities: An approach through built environment interventions, a case of Bhopal
No full textRegular physical activity reduces the rate of diabetes and other chronic diseases like blood pressure, cardiovascular disease etc. Despite this few people involve themselves in daily physical activity. The Healthy Community Movement is a growing global effort for the improvement of health and well-being of individuals and families, primarily through policies that sustain positive and lasting changes to local, state, and national systems and environments. The health of the community is not just a medical issue but rather affected by built, social, natural and economic environments. From various research studies, it was seen that if people have adequate paths to walk on, have destinations to walk to and people to stop and chat with and feel safe they are much more likely to engage in physical activity and walk instead of driving. In India, the approach of National Health Policy is just limited to development and improvement of health care systems. The policy does not have specify any role of built environment in shaping the health of an individual. Therefore, this research aims to develop a framework for promoting healthy communities by identifying parameters and its indicators related to built environment. The objectives of the research are to study and identify relationship between built environment and healthy communities;
to study various approaches and identify parameters and indicators that contributes for making healthy communities; to assess the health environment of communities through developed framework for study areas in Bhopal and finally prepare strategies and spatial plans for interventions to promote healthy communities. For assessment of health conditions two wards of Bhopal were selected, one located at core (ward 18) while another at periphery (ward 63) and assessed using HIART matrix inspired from HEART Urban matrix. The study involved an analysis of built environment conditions to find out what
discourages people from using Non-motorized transport through primary survey of the study areas. The results showed that lack of non-motorized transport infrastructure, high vehicle usage, unsafe streets, improper solid waste management, poor water quality, lack of open spaces and its maintenance leads to increase in diseases like diabetes, cardio vascular diseases, blood pressure, arthritis, cholera/ malaria/ gastric diseases etc. Planning interventions in shaping built environment to promote physical activity can act as an approach towards the healthy communities. Hence the study proposes detail planning
interventions which would be helpful in improving the health conditions of the communities. Also it proposes a framework to assess the health condition of the community thereby making it less prone to diseases. The further scope of the research would be to develop a model for healthy communities in terms of density, land use mix, housing and transportation which would promote healthy living among the communities

Stochastic stability of power systems
Get PDF"The utilization of synchronous machines in electric power systems as central generators and in electric drive applications as high-performance motors makes their modeling, simulation, state estimation, and analysis important in many scenarios; however, the multiple time-scale nature of the associated dynamic model, coupled with the presence of noise, complicates traditional methods.
We approach the problem in this work through dimensional reduction in nonlinear filtering. This can be understood as a combination of filtering and averaging. Recent advances in the development of particle filters are applied to the Single Machine Infinite Bus (SMIB) seven dimensional model of a synchronous generator and to the specific problem of a line contingency. Excellent system tracking coupled with significant computational savings are achieved.
In addition to system tracking, the traditional deterministic methods currently used in industry to quantify system stability are looked at from a Random Dynamical Systems (RDS) perspective. The maximal Lyapunov exponent (MLE) for a two dimensional model of a synchronous generator is calculated analytically to account for multiple white noise forcing elements. The ``real"" or colored noise case is also considered and an analytic expression derived.
Further, the presence of resonant zones and their stability for a two dimensional swing model is established. The stability of these zones is looked at from the Large Deviations perspective and is facilitated through an understanding of the Mean Exit Time. Numerical procedures are developed to calculate the Most Probable Exit Path along which; rare, long time transitions take place."Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-08-01The student, Vishal Chikkerur, accepted the attached license on 2017-07-14 at 13:01.The student, Vishal Chikkerur, submitted this Dissertation for approval on 2017-07-14 at 13:37.This Dissertation was approved for publication on 2017-07-14 at 15:32.DSpace SAF Submission Ingestion Package generated from Vireo submission #11473 on 2018-03-02 at 13:02:17Made available in DSpace on 2018-03-02T19:59:42Z (GMT).

The bard in Bharadwaj: Politics of transculturation in the cinematic adaptations of Shakespeare by Vishal Bharadwaj
No full textCinema adaptations play a vital role in recreating the imaginations. When the author scripts his ideas into a text, again the text in converted into visual by the director, where he is both an author and an adopter. This paper investigates the three adaptations of Shakespeare by Vishal Bharadwaj – Maqbool, Omkara and Haider. It argues that the adaptations are transculturating Shakespeare in the Indian context and like Shakespeare was a cultural commodity propagated by British imperialism, Bollywood is a cultural commodity of the hegemonic discourse of Indian Nationhood. Thus, the paper aims to study if by transculturating Shakespeare, Bharadwaj dismantles the narrative of Indian Nationhood or if he merely reinforces it despite situating it in the uncomfortable margins that threaten it. Finally, the paper locates the struggle between the narrative of nationhood and the counter narratives on the body of the female subject and studies the leads in 10 100 Identity and Marginalisation in South Asian Literature and Media Shakespeare’s plays transculturated onto Bharadwaj’s screen in this ligh
Investigation of bioclimatic design features in vernacular architecture of Northeast India: Case studies of Assam-type houses and stilt houses (Chang Ghar) in Assam, India
No full text664-673Bioclimatic design features in the buildings are based on surrounding geography and climate to create comfortable and healthy spaces. These features are observed in the vernacular architecture styles across the regions of India. Various bioclimatic design strategies are also observed in Northeast India; however, they are less focused when compared to other regions of India. Therefore, this paper attempts to investigate bioclimatic features in the vernacular architecture of Northeast India, wherein it focuses on two typologies, i.e., Assam-type house and Stilt houses (Chang Ghar). A qualitative analysis based on the site surveys was done to identify bioclimatic features used in the two selected typologies. The parameters selected to investigate bioclimatic features include the type of construction materials and methods used; the spatial arrangement of spaces; orientation and layout of the building; wall thickness; nearby open spaces; vegetation and water bodies; openings and ventilation; window to wall ratio; plinth height; design and material of shading devices; structure, height, and material of ceiling, any other special features. Overall, the results indicated that Assam-type houses and stilt houses are highly responsive to the local climate, utilizes locally available materials (bamboo, wood, and mud), and reflects the living style, customs, and socio-economic conditions. The outcome of this qualitative study was the identification of multiple bioclimatic features observed in both typologies. The recommendations from this study can act as a reference for designing buildings that shall promote sustainable built environments as per United Nations Sustainable Development Goal number 11 (Sustainable cities and communities)

Inventory and Modelling of Different Objective Functions and their Impact on Optimal Design of an Offshore Wind Farm
No full textThe design of an offshore wind farm (OWF) is multidisciplinary in nature as it involves the design of many disciplines such as the wake effects, support structure, electrical cables etc. For the optimal design of an OWF, an optimization procedure is required where all the disciplines are optimized simultaneously. The objective function plays a significant role in optimization as it expresses the main aim of the model which is to be either minimized or maximized. So far, cost of energy (COE) and annual energy production (AEP) are one of the commonly used objective functions for OWF optimization as far as the author is aware. However, there might be other objective functions that may influence the optimal design of an OWF as well. This may include maximizing the profit, minimizing the environmental impact, reducing their carbon emissions etc. Hence, this thesis investigates the overview of different objective functions and understand its impact on the optimal design of an OWF.An inventory of different objective functions is prepared, and relevant ones are selected for further study. It is observed that even though some objectives are dissimilar, they still depend on the same wind farm parameters and are therefore expected to give similar design results. From the list of objective functions, net present value (NPV) and risk management objectives are chosen for further research.The selected objective functions are then formulated in a metric for optimization. The price of electricity plays a significant role in determining the NPV. It is learnt that electricity price varies with the power supply depending on the site conditions. The electricity price is low if the supply of power is high in a region where there are many OWF’s and vice versa. Moreover, OWF investors value constant power output without any fluctuations. Hence, taking all these aspects into consideration, the electricity price in the NPV function is modelled for a constant value, wind variability and wind power predictability.The risk management function, on the other hand, aims at minimizing the uncertainty associated with an OWF project. The risk here refers to the uncertainty associated with the profit obtained from the OWF. A set of annual average wind speeds is computed using monte carlo simulations and the AEP and NPV are estimated. The mean( NPV_mean) and standard deviation ( NPV_std ) of NPV are then calculated. NPV_std represents the uncertainty in this scenario and is minimized to reduce the risk.A suitable method is then identified to deal with multiple objectives. The NPV function is maximized for maximum profit and this objective is evaluated using a single objective optimization technique. The risk management objective involves the calculation of NPV_mean and NPV_std. Both objectives are contrasting in nature as a significant reduction in NPV_std corresponds to an undesirable reduction in NPV_mean. A tradeoff between both these objectives is the best possible solution. Therefore, a multi- objective optimization technique is used, and a list of solutions is obtained by generating a pareto front.The new approach is then evaluated by implementing different case studies. It is observed that optimum rotor diameter and number of turbines for the single objective optimization technique are influenced by economic indicators such as the real interest rate and lifetime. However, they are not influenced by variation in the electricity price. Nevertheless, the NPV function is sensitive to the economic indicators and variation in the electricity price. For the multi - objective optimization technique, multi criteria analysis was used to determine the weight to the objective functions while moving along the pareto curve. It was observed that the improvement of one objective led to the deterioration of the other objective. Hence, the pareto front provides opportunities to investors to negotiate and decide on the weight they want to specify for their objectives.Electrical Engineering | Sustainable Energy Technolog
Higher order convergent fast nonlinear Fourier transform
No full textIt is demonstrated in this letter that linear multistep methods for integrating ordinary differential equations can be used to develop a family of fast forward scattering algorithms with higher orders of convergence. Excluding the cost of computing the discrete eigenvalues, the nonlinear Fourier transform (NFT) algorithm thus obtained has a complexity of O(KN+CpNlog2N) such that the error vanishes as mathop O(N-p) where p ϵ {1,2,3,4} and K is the number of eigenvalues. Such an algorithm can be potentially useful for the recently proposed NFT-based modulation methodology for optical fiber communication. The exposition considers the particular case of the backward differentiation formula (Cp=p3) and the implicit Adams method (Cp=(p-13,p>1) of which the latter proves to be the most accurate family of methods for fast NFT.Accepted Author ManuscriptTeam Raf Van de Pla
Fuzzy logic based active vibration control using novel photostrictive composites
No full textAlthough conventional actuators like piezoelectric and electrostrictive are efficient, but they required hard wiring, which contaminates the control signal and adds to the weight of the structure. The current study presents a wireless control strategy using photostrictive actuators. Owing to the fortunate combination of photovoltaic effect and converse piezoelectric effect, a photostrictive actuator can generate mechanical strain, when irradiated with light intensity. Limited choices of photostrictive material with high electromechanical coupling coefficient give the motivation to design photostrictive composites. The finite element-based formulation incorporating fuzzy logic controller is employed to study the active vibration control response of cantilever structure when equipped with photostrictive composite actuator. A parametric study has been carried out to study the influence of inclusion's volume fraction on wireless active vibration control of the structure. Control merits have been defined to compare the control performance of different composites. It is found that particulate composites are the better choice for lightweight structure and fiber composites are better if there is no weight constraint.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport Engineering and Logistic
