Abstract:
Purpose of the study: Uninterrupted hospital services and medical functions are the keys to functional resilience to cope with mass casualties. This paper presents the important level of resilience indicators for hospital functions to withstand natural disasters. Methodology: For the survey, 21 indicators are grouped into three domains focusing on i) general concerns of healthcare infrastructure planning ii) design and planning of hospital buildings iii) emergency service and management. The corresponding indicators were ranked on a Likert scale of 1 to 5. The authors collected 389 responses through an online survey of the healthcare professionals including disaster management professionals, medical officers, hospital architects, planners, project managers, and engineers. Main Findings: The data were analysed for determining the Relative Importance Index (RII) of each indicator. The top 7 indicators as an outcome of this research are: ‘access to the emergency services (0.861), ‘planning of refugee settlements’ (0.814), ‘uninterrupted supply of MEP services to critical units’ (0.871), ‘signages for internal circulation’ (0.845), ‘adaptive control, command, and communication system’ (0.848), ‘flexible spatial planning in case of a surge of patients’(0.813), ‘ensuring availability of healthcare workers with the provision of support infrastructure’ (0.758). Applications of this study: Assessment of the top indicators highlight the importance of ‘flexible design’ and ‘access to medical functions of a hospital building’. Based on these outcomes, it is proposed to develop a numerical framework for a comprehensive design appraisal of resilient hospital buildings.

Abstract:
Purpose: This study gives a critical assessment of the rainfall erosivity factor (R) for selected sites in the Majha region, representing different locations use of mean monthly rainfall data. Methodology: By applying empirical methods, the rainfall intensity for all the locations were obtained and was further determined at three different intervals of 30-minutes, 45-minutes and 60-minutes, respectively. The rainfall erosivity factor (R) was calculated by the revised universal soil loss equation (RUSLE). Main Findings: Using RUSLE, the rainfall erosivity factor (R) for each of the locations was measured as follows; EI = 3878.49 (MJmmha-1hr-1), EI = 4013.71 (MJmmha-1hr-1), EI = 4302.24 (MJmmha-1hr-1) for Majha region of Amritsar, Tarntaran and Pathankot respectively. A close observation of the data obtained revealed that as rainfall intensity increased with the duration, the rainfall erosivity index reduced or decreased. Implications of study: Nevertheless, it is expected that if proper cover crop and management practices are applied despite the region, the study area falls within, rainfall erosivity can be cushioned, thus reducing further erosion tendencies and enhancing food production chances from productive lands within the area. The novelty of study: The rainfall erosivity factor (R) was calculated by the revised universal soil loss equation (RUSLE).

Abstract:
Purpose of the study: The purpose of this work is to present an offline Optical Character Recognition system to recognise handwritten English numerals to help automation of document reading. It helps to avoid tedious and time-consuming manual typing to key in important information in a computer system to preserve it for a longer time. Methodology: This work applies Curvature Features of English numeral images by encoding them in terms of distance and slope. The finer local details of images have been extracted by using Zonal features. The feature vectors obtained from the combination of these features have been fed to the KNN classifier. The whole work has been executed using the MatLab Image Processing toolbox. Main Findings: The system produces an average recognition rate of 96.67% with K=1 whereas, with K=3, the rate increased to 97% with corresponding errors of 3.33% and 3% respectively. Out of all the ten numerals, some numerals like ‘3’ and ‘8’ have shown respectively lower recognition rates. It is because of the similarity between their structures. Applications of this study: The proposed work is related to the recognition of English numerals. The model can be used widely for recognition of any pattern like signature verification, face recognition, character or word recognition in another language under Natural Language Processing, etc. Novelty/Originality of this study: The novelty of the work lies in the process of feature extraction. Curves present in the structure of a numeral sample have been encoded based on distance and slope thereby presenting Distance features and Slope features. Vertical Delta Distance Coding (VDDC) and Horizontal Delta Distance Coding (HDDC) encode a curve from vertical and horizontal directions to reveal concavity and convexity from different angles.

Abstract:
Purpose of the study: We propose an approach to hide data in an image with minimum Mean Squared Error (MSE) and maximum Signal-to-Noise ratio (SNR) using Discrete Wavelet Transform (DWT). Methodology: The methodology used by us considers the application of Discrete Wavelet transform to transform the values of the image into a different domain for embedding the information to be hidden in the image and then using Singular Value decomposition we decomposed the matrix values of the image for better data hiding. Main Findings: The application of the SVD function gave the model a better performance and also RED pixel values with the High-High frequency domain are a better cover for hiding data. Applications of this study: This article can be used for further research on applications of mathematical and frequency transformation functions on data hiding. It can also be used to implement a highly secure image steganography model. Novelty/Originality of this study: The application of Discrete Wavelet Transform has been used before but the application of SVD and hiding data in the H-H domain to obtain better results is original.

Abstract:
Purpose of the study: Due to high solar radiation and extreme heat gain in composite climates, the envelope or the façade of the building becomes an essential part to modulate the heat transfer and temperature in the indoor environment. A passive sustainable approach to tackle heat gain is by adopting green living facades as the exterior skin. The objective of this research is to identify the potential of green living walls in modulating temperature and relative humidity in the composite climate of India. Methodology: This research is based on data collection in the form of a Case Study. The paper evaluates the difference of variation in temperature and relative humidity of two façade samples of the same building, one with a “green living facade” and one without it. Main Findings: The research aimed to justify that a green living facade may act as a passive strategy for composite climates. The result demonstrated that there is a significant temperature reduction between the ambient air temperature and indoor room temperature. The result also showed a notable change between ambient air temperature and the gap between the green living façade and the surface of the wall. Implications: Significant drop in indoor ambient temperature in composite climate may save energy for cooling or heating demands. Application of this study: This is a pilot study in order to carry out the main study for a similar application in order to categorize this as a passive sustainable façade strategy. Novelty/Originality of this study: The study is one of its kind attempt to investigate the impact of vertical green walls on thermal comfort in the composite climate of India.

Abstract:
Purpose of the study: The purpose of the study is to determine whether the partial relocation of Hazaribagh tanneries has any effect on the area’s soil quality with respect to chromium and to determine a possible link between human exposure/diseases to chromium, with the focus being placed on children and vulnerable population. Methodology: Geochemical sampling and public health research related to fieldwork (Focus Group Discussions, two In-Depth Interview, and Key Informant Interview). Main Findings: The study indicates that there is a significant presence of chromium in the area’s soil two years following the partial relocation of Hazaribagh tanneries. Flu-like symptoms, generalized skin rash, and fertility issues are common in the vulnerable population. The residents are ignorant, belong to the marginalized section of the society, and do not fully comprehend of the impact of environmental exposure to chromium. Applications of this study: The geochemical data may be used to identify in situ treatment technologies for remediation of the area’s soil. The public health data will allow health policymakers to generate ideas and implement solutions to one of the greatest health challenges faced by the impacted population. Novelty/Originality of this study: The study is multidisciplinary by nature and employs science and technology to systematically develop an insight into the environmental contamination resulting from the release of untreated effluent and solid waste containing chromium.
