    Traversing ambiguities : rebuilding perspectives through designed visual education

    Get PDF
    We perceive the world largely through categorizations and associations. We distill people, objects and entities into extremes. ‘Normal’ becomes a measure of acceptable. Reductionist definitions, force anything ambiguous or uncertain to be rejected. Acknowledging our biases towards these misinterpreted, shunned or ignored entities, has long been overdue. In todays world we cannot possibly continue being blind to complexity. Can designed visual education reinterpret ambiguity and embrace multiplicity? How can a designer’s perspective help scaffold these educational systems? Can we do so by looking deep within our own practice as designers, artists, scholars and educators? The thesis explores these various questions through the perspective of a designer and scholar. By delving into historic and current examples of association, the ideas of interpretation and representation are discussed through the analogy of a unique creature, the pangolin. These learnings are then applied to examples of designed visual education. The thesis advocates the use of visual narratives to help preserve or rekindle a childlike worldview of acceptance and inclusion. Designed visual education helps us move beyond knowing and encourages emotional investment, building deep-rooted resilience. Design interventions, in any form are a systemic process of responsible creation, iteration and adaptation. If paired with appropriate mediums of dissemination, we could nurture the future generations to be strategic thinkers, hopefully bringing about longterm impact

    With the rapid increase and availability of seismic data, an automatic, transparent and regular way of earthquake hazard estimation strategy is highly desirable in many seismically active large geographical regions. In this paper, we implement a novel method of nowcasting (Rundle et al., 2016) that can indirectly assess the current progression of a region through its earthquake cycle of large events. Nowcasting differs from the method of forecasting in which future earthquake probabilities are calculated. Using statistics of natural times, counts of small earthquakes between large earthquakes in a defined region, nowcasting provides an earthquake potential score (EPS) to enable scientists and city planners a snapshot of the current level of earthquake hazard in the region. Applied to a number of selected major cities in the northwest Himalaya and surrounding regions, we found that the EPS values corresponding to M ≥ 6 events in New Delhi, Chandigarh, Dehradun and Shimla reach about 0.56, 0.87, 0.85 and 0.88, respectively. These estimated scores thus indicate that New Delhi is about half-way through its cycle for magnitude 6.0 or higher earthquakes, while Dehradun is about 85 percent of the way through its cycle. Towards the end, we discuss some implications and applications of these nowcast values to improve the present earthquake hazard assessment practice in the study region

    Emerging role of transesophageal echocardiography in severe chronic obstructive pulmonary disease

    Get PDF
    Background: Pulmonary hypertension (PH) secondary to chronic obstructive pulmonary disease (COPD) has a prevalence from 20 to 91% depending on the definition of PH (mPAP >20 versus >25 mmHg). Pulmonary vasoconstriction, pulmonary vascular remodeling, endothelial dysfunction, inflammation and destruction of the pulmonary vascular bed being the common mechanisms behind. Transthoracic echocardiograms (TTE) though the most important non-invasive tool to measure degree of PH, may give false negative results in severe COPD cases due to poor echo window. This could be overcome by doing transesophageal echocardiograms (TEE) in those cases, which is, though invasive but gives good results. The aim of the study was to evaluate the role of transesophageal echocardiography in COPD patients.Methods: Total 100 patients of COPD were evaluated for PH via TTE and TEE was performed in all those 33 patients whose TTE were non-confirmatory due to poor echo window.Results: There were 0% patient with poor echo window in COPD grade 1, 18.18% in grade 2, 42.2% and 39.39% in grade 3 and grade 4 respectively. P-value obtained was statistically significant P <0.001. Out of 33 COPD patients with poor echo window, In grade 3 and grade 4, 64.2% and 76.9% patients had TEE findings respectively while in grade1 and grade 2 0% and 33.33% patient had TEE finding.Conclusions: TTE though is an excellent tool for diagnosing  pulmonary artery hypertension in COPD patients, has its limitation especially in severe COPD cases due to poor echo window which may give false negative results. So TEE should be recommended in all those severe COPD cases that have poor echo window

    EARTHQUAKE FORECASTING USING ARTIFICIAL NEURAL NETWORKS

    Earthquake is one of the most devastating natural calamities that takes thousands of lives and leaves millions more homeless and deprives them of the basic necessities. Earthquake forecasting can minimize the death count and economic loss encountered by the affected region to a great extent. This study presents an earthquake forecasting system by using Artificial Neural Networks (ANN). Two different techniques are used with the first focusing on the accuracy evaluation of multilayer perceptron using different inputs and different set of hyper-parameters. The limitation of earthquake data in the first experiment led us to explore another technique, known as nowcasting of earthquakes. The nowcasting technique determines the current progression of earthquake cycle of higher magnitude earthquakes by taking into account the number of smaller earthquake events in the same region. To implement the nowcasting method, a Long Short Term Memory (LSTM) neural network architecture is considered because such networks are one of the most recent and promising developments in the time-series analysis. Results of different experiments are discussed along with their consequences

    This study was carried out as split split plots in a randomized complete block design with three replications at Research Field of Agriculture Faculty, during 2014-2015 in Iran. In this study, the main factor was two safflower cultivars including: Sina and Faraman and subplot were foliar application of fulvic acid in 2 stages as: stem elongation and flowering and also sub sub plot were 3 different fulvic acid concentrations including as: 0: control (distilled water), 0.5 and 1 kg*ha-1. The results showed that the characters including: numbers of seed in head, 1,000 seed weight, seed yield, harvest index and oil percent were affected significantly by safflower cultivars, and also head weight were affected in different growth stages. Also the results of fulvic acid were showed significant different about head numbers, numbers of seed in head, biological yield, harvest index and oil percent. In this study the maximum seed yield and oil percent were achieved by Faraman cultivar in comparison with Sina, as it produced 14.33 and 19.5 percent more seed yield and oil percent in arrangement. Foliar application in stem elongation stage obtained 6.02 percent more seed yield but in flowering stage, fulvic acid spraying were achieved 35.5 percent more oil percent. Finally the results showed the positive effects of foliar application of fulvic acid in 1 kg*ha-1, as it produced 85.67 percent more oil percent in comparison with control

    GPS-BASED MONITORING OF CRUSTAL DEFORMATION IN GARHWAL-KUMAUN HIMALAYA

    Get PDF
    The Himalayan region has experienced a number of large magnitude earthquakes in the past. Seismicity is mainly due to tectonic activity along the thrust faults that trend parallel to the Himalayan mountain belt. In order to study the ongoing tectonic process, we report Global Positioning System (GPS) measurements of crustal deformation in the Garhwal-Kumaun Himalaya through two continuous and 21 campaign stations. We collect GPS data since 2013 and analyze with the GAMIT/GLOBK suite of postprocessing software. Our estimated surface velocities in ITRF2008, India-fixed, and Eurasia-fixed reference frame lie in the range of 42&ndash;52&thinsp;mm/yr, 1&ndash;6&thinsp;mm/yr, and 31&ndash;37&thinsp;mm/yr, respectively. We observe insignificant slip rate (&sim;&thinsp;1&thinsp;mm/yr) of HFT that indicates its locking behavior. The slip rates of MBT and MCT, however, are consistent with the seismic activity of the study region
