Irreversibility as a Structural Requirement for Meaningful Conscious Experience
No full textIrreversibility as a Structural Requirement for Meaningful Conscious Experience Author: Tushar Chaand Abstract This work proposes that meaningful conscious experience requires irreversible temporal constraint as a necessary structural condition. While physical theories often treat time asymmetry as emergent or secondary, lived experience exhibits a strict one-way temporal ordering without which consequence, responsibility, and narrative coherence collapse. By analyzing reversibility, memory continuity, and choice, this framework demonstrates that backward temporal traversal with memory continuity would eliminate meaning by erasing irreversible consequence. The theory is ontology-agnostic and remains compatible with physicalist, block-universe, multiverse, and simulation interpretations. Its contribution is to identify irreversibility not as a contingent feature of reality but as a functional requirement for any system capable of hosting meaningful experience. Core Claims 1. Conscious experience requires temporal ordering. 2. Meaning arises only when outcomes cannot be undone. 3. Memory continuity combined with reversibility collapses consequence. 4. Meaningful experience therefore requires irreversible temporal constraint. Axioms Axiom 1: Conscious experience requires sequential temporal structure. Axiom 2: Meaning requires irreversible outcomes within experience. Axiom 3: Memory continuity is necessary for learning, identity, and responsibility. Axiom 4: Backward temporal traversal with memory continuity eliminates meaning. Postulates Temporal asymmetry is experientially necessary. Irreversibility is local to conscious trajectories. Meaning is perspective-relative rather than globally defined. Ethical responsibility emerges from irreversible interaction. Falsifiability This framework would be weakened if meaningful conscious experience were demonstrated without temporal ordering, if backward time traversal preserved consequence, or if unlimited reversibility supported stable narrative identity. Conclusion Irreversibility is not a limitation imposed on experience but a structural requirement for meaning itself. Any reality capable of hosting meaningful conscious agents must enforce temporal asymmetry and excluded possibility, regardless of its underlying ontology

Understanding drought propagation and its implications for drought management
No full textDroughts have been recognized as one of the most complex natural disasters, especially because they involve interactions between numerous climatological, hydrological and human processes. During a drought event, deficits in precipitation gradually translate into deficits in soil moisture, streamflow, and aquifer and reservoir storages, and eventually result in deficits in water supply for meeting human and environmental requirements. This translation process is known as drought propagation. The drought propagation mechanism of a region is influenced by its climate, watershed and human water use characteristics. Different drought propagation mechanisms from meteorological drought to hydrological drought and to agricultural and water supply drought can result in very different outcomes in terms of magnitude and duration of deficits in water availability during droughts. The objective of this dissertation is to understand drought propagation mechanisms and their controlling factors in different regions of the contiguous US (CONUS), and to provide a holistic framework for the assessment of drought impacts on natural and human systems. The first part of the dissertation focuses on meteorological droughts, which are defined as periods with deficient rainfall. The spatial and temporal patterns of multi-decadal variability of meteorological droughts are analyzed to quantify the non-stationarity in meteorological drought risk. Furthermore, the regional drivers of multi-decadal variability are identified for the assessment of meteorological drought risk in the near future. The second part of the dissertation focusses on hydrologic droughts, which are defined as periods with water deficits in streams and aquifers. The propagation of meteorological to hydrologic droughts is studied to understand how both climate and watershed properties contribute to different characteristics of hydrologic droughts in different regions. By taking the drought propagation mechanisms into consideration, the third part of the dissertation evaluates the impact of droughts on water supply systems in the CONUS and explores how the management of surface and groundwater resources in different regions can be improved. Finally, the understanding of drought propagation mechanisms is applied for identifying hotspots of drought impacts on natural and human systems in the CONUS and for providing insights for regional drought risk mitigation in the near future.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-08-01The student, Tushar Apurv, accepted the attached license on 2020-07-07 at 10:57.The student, Tushar Apurv, submitted this Dissertation for approval on 2020-07-07 at 11:16.This Dissertation was approved for publication on 2020-07-09 at 15:01.DSpace SAF Submission Ingestion Package generated from Vireo submission #15509 on 2020-10-02 at 15:31:27Made available in DSpace on 2020-10-07T22:44:25Z (GMT).

Regulation of shale gas development : an argument for state preeminence with federal support
No full textThesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2012.Cataloged from PDF version of thesis.Includes bibliographical references (p. 106-118).Shale gas development has become big business in the United States during the past decade, introducing drilling to parts of the country that have not seen it in decades and provoking an accelerating shift in the country's energy profile. State governments, which have historically regulated the oil and gas industry and continue to do so today, were in many cases caught by surprise by the speed and the scale of the shale gas boom and are still trying to update and adapt their regulatory practices to respond to the impacts that shale gas development is causing in communities in their states. In some instances, these impacts have included groundwater and surface water contamination, air pollution, exploded homes, and damage to wetlands and other habitats, among other impacts. Shale gas development has also created jobs, brought economic development to distressed communities, lowered fuel costs, and has begun to supplant coal in the nation's electricity supply. The thesis seeks to understand whether primary regulatory authority over shale gas development should rest with the states or with the federal government. In answering this question, the author applies theory from the field of regulatory federalism to the practice of shale gas development to ascertain whether the federal government or state governments are best suited to regulate shale gas development. Grounding the analysis in both regulations as-written and as-applied in a number of states that have active shale gas industries, the author uses four key criteria to gauge whether regulatory authority should rest with the central government or with the states. These four criteria are: the geographic distribution of costs and benefits associated with shale gas development; regulatory capacity at the federal level and at the state level; which level can better foster innovation, flexibility, and adaptability; and which level can better provide efficiency, certainty, and stability. The analysis finds that, in most cases, states are better situated than the federal government to regulate shale gas development on the basis of each of the four criteria. The author also subjects current regulatory practice to a two-part test to determine whether regulatory failure is currently occurring that would compel the federal government to assume regulatory authority. The results from this test are negative. The author concludes that primary regulatory authority over shale gas development should remain with state governments. Finally, the author provides four policy recommendations, two each to state governments and to the federal government, to improve regulatory practice and outcomes in the future.by Tushar Kansal.M.C.P
A Material Model Optimization Approach for the Sheet Metal Forming Process Using the Hole Expansion Test
No full textPublisher Copyright: © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.Sheet metal forming is an important manufacturing process widely used to produce complex stamped parts from flat sheet stock in industries such as automotive and packaging. Due to the global economic climate, these industries need to be highly competitive by reducing production costs and increasing process efficiency. Numerical simulation combined with sheet metal forming expertise is one of the technological innovations adopted to meet these requirements by reducing the traditional time-consuming and costly testing steps. With the progress of finite element simulation, questions about the accuracy or limitations of the type of material description adopted have become particularly important. The influence of the plasticity model is examined in this work by a numerical study using the hole expansion test. This work first presents the yield locus criterion adopted and developed by Tata Steel, which is hereafter referred to as the Tata Steel material model. Hole expansion tests are performed at different hole diameters and the results are compared with FE simulation. The simulations are performed with the finite element software Autoform R11 in which the yield criterion proposed by Abspoel & Scholting [1] has been implemented. The discussion therefore focuses on the influence of the material model on the numerical predictions and its accuracy based on the optimization of the different material parameters measured.The authors would like to acknowledge experimental work carried out at Tata Steel R&D by Frank Schouten and Tushar Khandeparkar.Peer reviewe
Modeling and monitoring of cardiovascular dynamics for patients in critical care
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 231-239).In modern intensive care units (ICUs) a vast and varied amount of physiological data is measured and collected, with the intent of providing clinicians with detailed information about the physiological state of each patient. The data include measurements from the bedside monitors of heavily instrumented patients, imaging studies, laboratory test results, and clinical observations. The clinician's task of integrating and interpreting the data, however, is complicated by the sheer volume of information and the challenges of organizing it appropriately. This task is made even more difficult by ICU patients' frequently-changing physiological state. Although the extensive clinical information collected in ICUs presents a challenge, it also opens up several opportunities. In particular, we believe that physiologically-based computational models and model-based estimation methods can be harnessed to better understand and track patient state. These methods would integrate a patient's hemodynamic data streams by analyzing and interpreting the available information, and presenting resultant pathophysiological hypotheses to the clinical staff in an effcient manner. In this thesis, such a possibility is developed in the context of cardiovascular dynamics. The central results of this thesis concern averaged models of cardiovascular dynamics and a novel estimation method for continuously tracking cardiac output and total peripheral resistance. This method exploits both intra-beat and inter-beat dynamics of arterial blood pressure, and incorporates a parametrized model of arterial compliance. We validated our method with animal data from laboratory experiments and ICU patient data.(cont.) The resulting root-mean-square-normalized errors -- at most 15% depending on the data set -- are quite low and clinically acceptable. In addition, we describe a novel estimation scheme for continuously monitoring left ventricular ejection fraction and left ventricular end-diastolic volume. We validated this method on an animal data set. Again, the resulting root-mean-square-normalized errors were quite low -- at most 13%. By continuously monitoring cardiac output, total peripheral resistance, left ventricular ejection fraction, left ventricular end-diastolic volume, and arterial blood pressure, one has the basis for distinguishing between cardiogenic, hypovolemic, and septic shock. We hope that the results in this thesis will contribute to the development of a next-generation patient monitoring system.by Tushar Anil Parlikar.Ph.D
Investigations Towards Developing Automated Energy Diagnostics and Prediction Models, Based on BMS Sensor Data Analysis
No full textAn investigation into energy optimization techniques for buildings was initiated that led to the development of a Toolbox with several functions for analysis, optimization and prediction techniques for thermal energy demand of a school building. The HHS, or The Hague University of Applied Sciences in Delft, was the most sustainable building for the years 2011-2012. Naturally, the building also incorporated features and capabilities which can help an engineer to study methods of making a smart building, better. Using sensor driven data from stored databases in the building, optimization and analysis tools have been developed for the building, at the room level. These analyses are automated into the toolbox for any given room of the building, with minor changes. The goal is to help an expert analyze the room in a quick and efficient manner. Using the indoor/outdoor climate data, occupancy related profiles, and internal heat loads, the model can also generate predictive patterns and determine the explanatory power of each of these variables on the thermal energy demand of a room. To do this, the Toolbox is designed with two predictive modeling techniques, unique in their own ways. The first being a Multivariate Linear Regression model, that allows for estimation of thermal demean based on a linear thermal balance equation of the room. This is followed by the use of Artificial Neural Networks, to dive deep into the intricacies of the complex data of a room, especially in the case of a highly controlled indoor climate of a room. The goal here was to understand the predictive capacity of these techniques over a) real time data, and b) over the data belonging to a room and not the entire building. Finally, looking outwards to optimizing energy demands of buildings, this Toolbox, aims at estimating quick wins that can be gathered from a smart building, to reduce energy demand further and tend the building towards nearly zero energy in the future.
