As microscopic swimmers survive in nature, they have evolved unique structures and swimming patterns under the water, which has special advantages. The movement of bacteria at low Reynolds number (Re) environment has aroused extensive research interest. The two typical swimming methods of bacteria are introduced in this paper. Based on this, we are inspired to design the bionic robot on a micro scale, which is an artificial structure that imitates the external shape, movement principle and behavior mode of organisms in nature. Compared with traditional robots, nano bionic robots are easier to miniaturize. They also have higher maneuverability so that they can move continuously and flexibly. We expect to simulate its motion at low Reynolds number (Re) fluids and explore complex future applications in different fields.

This paper proposes a new approach for the non-invasive detection of Anaemia using the images of anterior conjunctival pallor captured by the Smartphone. The aim of this research work is to integrate technology with the visual detection technique used by the clinicians to estimate the anaemia detection for quick preliminary diagnosis as well as follow-ups, especially in the remote areas of India where accessibility & affordability of healthcare services is still a major concern.
The objective of this research work is to introduce the automation of healthcare facilities in remote areas of India by developing an open-source website integrated with an accurate computational based algorithm. The proposed algorithm developed could achieve 81.27 % accuracy for the detection of Anaemia and with further improvement can be a viable alternative to the existing methods for anaemia detection thereby creating a humanitarian impact.

This paper studies how artificial intelligence (AI) and machine learning (ML) have an impact on healthcare service delivery, specifically on patient care in the Indian healthcare scenario. The study tries to understand the impact in different areas of health service, both the utopian and dystopian views, and the antecedents of AI in healthcare services. It then exploresthe Indian healthcare scenario to understand the applicability of AI there. The paper performs a detailed literature review on AI in healthcare by looking into the journals and articles published in last two years. A conceptual framework was developed based on the findings and the gaps identified in the literature. Five independent variables were identified: data governance, workforce competency, patient voice, predictive medicine, security and privacy. Five sub variablesunder each of the dependent variables were further identified and a conceptual framework was developed to measure patient experience. This work provides a novel framework integrating different factors while discussing several barriers and benefits of AI-ML based health. In addition, five insightful propositions emerged as a result of the main findings. Further quantitative study can be done to establish the relationship between the factors and establish the validity of the model.

Many different pregnancy complications cause a decrease in the gestation period of mothers. Due to which babies with immature lungs and organs are given birth. But the baby cannot survive in the outer environment with immature organs. Thus it implicitly involves a series of special care focused on the monitoring of the evolution in terms of weight gain, movements of the baby, etc. Therefore, the use of incubators is emerging continuously. But in cities like Bangladesh having many complications like this, it is not feasible for all families to use incubators as the majority of families residing there are below the poverty line. For such a problem low-cost infant incubator has come into the light. This article is an attempt to understand various methods to create a low-cost neonatal incubator that is portable, affordable, and efficient in use. The papers cited below use a microcontroller as the source for processing the data and some of the results are somewhat simulated using a fuzzy logic system. This is a review paper based upon different methods of development of a low-cost infant incubator.

This paper presents a current-mode square-rooting circuit with electronically tuned based on off-the-shelf IC. The proposed circuit has a simple structure. It has been designed by using three LT1228s without the employment of additional passive elements. The output current can be linearly/electronically adjusted with a wide input dynamic range. The proposed circuits performance is proved by real-practical testing. Its experimental results agree well with the theory. Furthermore, the output current of the proposed circuit is temperature-insensitive.

This study aims to determine the impact of land use changes on flood discharge in the Keramasan watershed and to calculate the flood discharge used the rational method. The data used in this study include rainfall data, land use data and topographic data. Rainfall data used is daily rainfall data recorded at BMKG Kenten Palembang. Daily rainfall is transformed into hourly rainfall intensity using the Mononobe method. The results of this study indicated that the increase in flood discharge due to changes in land use is approximated by the linear trend equation Y = a + b*X1 + c*X2 + d*X3. Variable Y is flood discharge. The variables X1, X2, and X3 are the area of rice fields, the area of agricultural land, and the area of housing. The combination correlation coefficient is 0.969. it’s mean that 96,9 % of variable flood discharge influence of the Variables of rice fields, the area of agriculture land and the housing area. Where the coefficient a, b, c, and d are –350.60, 33.63, -75.00, and 1.006. The partial correlation coefficient, RYX1 is 0.57, RYX2 = 0.57, and RYX3 = 0.57.

Thermal control of electronics aims to maintain their temperature within the recommended temperature range. Satellite avionics are getting smaller and have a higher power density. Furthermore, the heat transfer modes in space are limited to conduction and radiation, which makes thermal control more difficult. Thermal energy storage materials are a promising candidate for the thermal control of satellite avionics. Solid-liquid Phase change materials (PCMs) are latent heat thermal storage materials that store and release thermal energy during melting and solidification. The best method for using the PCMs in thermal control of satellite avionics is PCM encapsulation. PCM encapsulation refers to packing the PCM into a closed rigid container to isolate it from the surrounding. In the present work, a PCM-based heat sink was adopted for thermal control of a small satellite subsystem. The heat sink was made of aluminium due to its relatively high thermal conductivity and was designed based on the outer dimensions of a small satellite subsystem. RT 35, RT 31, and RT 24 were used as the PCM materials, and thermal conductivity enhancers (TCE) with different geometries were used to get over the lower thermal conductivity of the PCM. The present study delivers a transient numerical investigation of the effect of TCE geometry on the thermal control performance of the PCM-based heat sink. Circular pin fins, triangular pin fins, and novel metal foam geometry were used with a TCE volume fraction of 20 %. The electronic subsystem was assumed to be "ON" for 10 min generating 20 W of heat, and "OFF" for 80 min. During the cycle, the heat sinks base plate temperature and the liquid fraction of PCM were recorded. The results showed a significant decrease in the base plate temperature when the PCM was used. RT 24 reduced the temperature by about 46 % compared to the case without PCM. At the lower melting points PCM recorded a higher liquid fraction. RT 24 increased the liquid fraction by 27.7 %. The results also concluded that the novel metal foam geometry significantly enhanced thermal performance and delivered the lowest base plate temperature.

This paper represents the results of a capstone project that took place in the mechanical engineering department at Abu Dhabi Mens College. Emphasis was placed on determininghow much cooling can be stored in a 10 L water tank from 3 water thermoelectric coolers(WTCs) connected thermally in series. The results obtained were analyzed for 3 different scenarios, a) one WTC, b) 2 WTCs, c) 3 WTCs and two different mass flow rates of 0.02 kg/s and 0.04 kg/s. A decrease in the water storage tank temperature with time was shown under all the conditionsthe experiments were conducted. On the other hand an increase in the amount of cooling capacity in the water storage tank was observed. Of interest,the results showed that the rate with which the storage tank temperature gradient and consequently the amount of cooling stored decreased as the number of the connected WTCs was increased.
