In this work, a novel approach for airborne filtration with particular reference to medical (non-oil) medical mask is discussed. Here, and contrariwise to current approaches, filtration is attained neither by reducing the hydraulic diameter of the pore nor by increasing the fibre layers thickness-both of them with a strong penalty in the breathability of the mask, but rather by...
We report the development of a finite-element-based solver to compute transport of mass, momentum and energy during evaporation of a sessile droplet on a heated surface. The evaporation is assumed to be quasi-steady and diffusion-limited. The heat transfer between the droplet and substrate and mass transfer of liquid-vapor are solved using a two-way coupling. In particular, here...
The illegal harvesting of seafood and the mislabelling of dry fish products have become more prominent in recent years. Traceability in the dry fish supply chain deserves research attention, especially among small and medium enterprises (SMEs) in a developing country like India. To implement the traceability system, it is necessary to identify the variables and their inter...
The present study deals with the analysis of daily average concentrations of respirable suspended particulate matter (RSPM- PM10), sulfur dioxide (SO2), and nitrogen dioxide (NO2) at seven monitoring stations namely, Hazratganj, Talkatora, Mahanagar, Aliganj, Sarai Mali Khan, Gomtinagar, and Ansal TC in Lucknow city from 2016 to 2020. The analysis shows that the annual average...
Drainage systems contain biological contaminants like bacteria and viruses flowing through them. Additionally, these pipelines also have organic matter known as biofilms growing on their walls. These biofilms infact act as incubation zones for further growth of bacteria and coronaviruses. Standard water treatment routines with traditional cleaning agents are known to be not able...
Biomedical Event Extraction (BEE) is a demanding and prominent technology that attracts the researchers and scientists in the field of natural language processing (NLP). The conventional method relies mostly on external NLP packages and manual designed features, where the features engineering is complex and large. In addition, the conventional methods on BEE uses a pipeline...
Sufficient numbers of staff are required for any hospital for providing better services to patients with satisfactory treatment. In most hospitals, the patient's treatment and care depend on the availability of nurses. Less number of nurses are a reason for average care and treatment to patients, whereas more than the required number of nurses may cause wastage of expenditure and...
Due to the pandemic, most of the personal transactions relating to finance, commerce and healthcare services have gone online making privacy preservation a critical requirement. Consequently, privacy has been made a critical parameter in Data Protection Regulations leading to the search for such a privacy compliant system which is also resilient to attacks. A detailed analysis of...
The present paper deals with the studies on the change in concentration of three standard pollutants namely, respiratory suspended particulate matter (RSPM or PM10), Sulphur dioxide (SO2) and Nitrogen dioxide (NO2) because of lockdown in India to prevent the spread of COVID-19 pandemic in 2020. The monthly average concentrations of the above pollutants observed at four monitoring...
Modelling of population dynamics of epidemic diseases is crucial in developing effective strategies for curbing the diseases. It helps us identify the various parameters that can help control the epidemic if the modelling is done carefully. Physical modelling of the dynamics in the form of circuits and systems can augment the understanding of disease mechanisms. In this paper, we...
Recently, there is incredible progress in the arena of machine learning with generative adversarial network (GAN) methods. These methods tend to synthesize new data from input images that are highly realistic at the output. One of its applications in the image-to-image transformation way is the face aging task. In the face aging process, new face images are synthesized with the...
We review recent studies on fomite transmission of COVID-19, caused by the novel coronavirus. In particular, we focus on survival time of coronavirus on solid and porous surfaces. Since the aqueous phase of a respiratory droplet serves as a medium for virus survival, evaporation of the droplet on a surface plays a crucial role in determining the virus survival time. While the...
In this paper, I propose the platform business model to transform the classical Hospital model using the new digital technologies. The ecosystem framework is developed for healthcare service sector where all the stake holders including the core health providers (Hospitals, Pharma manufacturers), Complementors (Diagnostic labs, Pharmacies, Startups), Homecare providers, Software...
We numerically modeled the droplets’ size distribution of sneezing action from the COVID-19 patient, without considering the viral loading of droplets. Thus, we assumed the behavior of COVID-19 droplets same as that of standard water droplets. In this work, we evolved the initial Weibull distribution (typically used for representing the saliva droplets size distribution) using a...
Understanding of airflow dynamics in the human pulmonary acinus is important for increasing targeted drug effectiveness and determining the health impact of toxic aerosols. However, there is a lack of quantitative data about the pulmonary airflow in realistic and flexible idealized geometries. This paper aims to numerically analyse the flow field of the pulmonary acinus using the...
Retinal imaging helps to detect retinal and cardiovascular abnormalities. Among these abnormalities, Diabetic Macular Edema (DME) and Age Related Macular Degeneration (AMD), both are frequent retinal degenerative diseases leading to blindness. Content based retinal OCT scan retrieval process makes use of characteristic features to retrieve similar Optical Coherent Tomography (OCT...
The pandemic COVID-19, caused by SARS-COV-2 virus has shaken the entire world with no such remedy till date. The only possible way to stop transmission of SARS-COV-2 is to take safety precautions including use of facemask. With the ever-increasing concern on the disease, it is necessary to choose facemask components to achieve the performance as good as commercially available N95...
The infectious diseases with a viral origin are of significant worldwide concern. In recent times, pandemics are creating havoc across the entire globe. This paper presents a constructive analysis of a new mathematical concept that will help the medical authorities to predict and to take controlling measures. In this work, we use ordinary first-order differential equations and...
In this paper, it is proposed to understand the opinion of the public regarding the policy of demonetization that is implemented recently in India through Aspect-based Sentiment Analysis (ABSA) that predicts the sentiment of specific aspects present in the text. The major aim is to identify the relevant contexts for various aspects. Most of the conventional techniques have...
