Rapid multi sample DNA amplification using rotary-linear polymerase chain reaction device (PCRDisc)
Multiple sample DNA amplification was done by using a novel rotary-linear motion polymerase chain reaction (PCR) device. A simple compact disc was used to create the stationary sample chambers which are individually temperature controlled. The PCR was performed by shuttling the samples to different temperature zones by using a combined rotary-linear movement of the disc. The device was successfully used to amplify up to 12 samples in less than 30 min with a sample volume of 5 μl. A simple spring loaded heater mechanism was introduced to enable good thermal contact between the samples and the heaters. Each of the heater temperatures are controlled by using a simple proportional–integral–derivative pulse width modulation control system. The results show a good improvement in the amplification rate and duration of the samples. The reagent volume used was reduced to nearly 25% of that used in conventional method
Estimating social distance in public places for COVID-19 protocol using region CNN
The Coronavirus disease has spread throughout the world and its fear has made people to be more cautious in public places. Since precautionary measures are the only reliable protocol to defend ourselves, social distancing is the only best approach to defend against the pandemic situation. The reproduction number i.e. R0 factor of COVID-19, can be slowed down only through the physical distancing norms. This research proposes a deep learning approach for maintaining the social distance by tracking and detecting the people present indoor and outdoor scenarios. Surveillance video is taken as the input and applied into you only look once (YOLO) V3 algorithm. The persons in the video are identified based on the segmentation algorithm present within the framework and then using Euclidean distance the image is evaluated. The bounding box algorithm helps to segregate the humans based on the minimum distance threshold. The proposed method is evaluated for images with peoples in the market, availing essential commodities and students entry inside a campus. Our proposed region-based convolutional neural network (RCNN) algorithm gives a better accuracy over the traditional models and hence the service can be implemented in general for places where social distancing is mandatory
Monitoring of the Social Distance between Passengers in Real-time through Video Analytics and Deep Learning in Railway Stations for Developing the Highest Efficiency
Near the end of December 2019, the globe was hit
with a major crisis, which is nothing but the coronavirusbased
pandemic. The authorities at the train station should
also keep in mind the need to limit the spread of the covid
virus in the event of a global pandemic. When it comes to
controlling the COVID-19 epidemic, public transportation
facilities like train stations play a pivotal role because of the
proximity of so many people who may be exposed to the
virus. Using common place CCTV cameras and deep
learning with simple online and real-time (DeepSORT)
methods, this study develops social distance monitoring
using a YOLOv4 identification of a Surveillance Object
Model. Based on experiments conducted with a
minicomputer equipped with an Intel 11th Gen Intel(R)
Core(TM) i3-1115G4 at 3.00GHz, 2995 Mhz, two Core(s),
four Logical processor, four gigabytes of random-access
memory (RAM), this paper makes use of CCTV
surveillance, which was put into practice at the Guindy
railway station, Chennai, Tamilnadu in India in order to
detect the violation of social distancing
Optimal knowledge extraction technique based on hybridisation of improved artificial bee colony algorithm and cuckoo search algorithm
We present a framework that we are currently developing, that
allows one to extract knowledge from the knowledge discovery in database
(KDD) dataset. Data mining is a very active and space growing research area.
Knowledge discovery in databases (KDD) is very useful in scientific domains.
In simple terms, association rule mining is one of the most well-known
methods for such knowledge discovery. Initially, database are divided into
training and testing for the aid of fuzzy generating the rules using fuzzy rules
generation the set of rules are generated from the given dataset. From the
generated rules, we are extracting the significant rules by using the improved
artificial bee colony algorithm and cuckoo search algorithm (IABCCS). After
extracting optimal knowledge from the dataset via rules, the data will be
classified using fuzzy classifier with the aid of this finally we will classify the
attack and normal
A technique to stock market prediction using fuzzy clustering and artificial neural networks
Stock market prediction is essential and of great interest because success-
ful prediction of stock prices may promise smart benets. These tasks are highly
complicated and very dicult. Many researchers have made valiant attempts in
data mining to devise an ecient system for stock market movement analysis. In
this paper, we have developed an ecient approach to stock market prediction by
employing fuzzy C-means clustering and articial neural network. This research has
been encouraged by the need of predicting the stock market to facilitate the investors
about buy and hold strategy and to make prot. Firstly, the original stock market
data are converted into interpreted historical (nancial) data i.e. via technical indi-cators. Based on these technical indicators, datasets that are required for analysis
are created. Subsequently, fuzzy-clustering technique is used to generate dierent
training subsets. Subsequently, based on dierent training subsets, dierent ANN
models are trained to formulate dierent base models. Finally, a meta-learner, fuzzy
system module, is employed to predict the stock price. The results for the stock
market prediction are validated through evaluation metrics, namely mean absolute
deviation, mean square error, root mean square error, mean absolute percentage
error used to estimate the forecasting accuracy in the stock market. Comparative
analysis is carried out for single Neural Network (NN) and existing technique neu-
ral. The obtained results show that the proposed approach produces better results
than the other techniques in terms of accuracy

User Activity Analysis Via Network Traffic Using DNN and Optimized Federated Learning based Privacy Preserving Method in Mobile Wireless Networks
Mobile and wireless networking infrastructures are facing unprecedented loads due to increasing
apps and services on mobiles. Hence, 5G systems have been developed to maximise mobile user
experiences as they can accommodate large volumes of traffics with extractions of fine-grained data
while offering flexible network resource controls. Potential solutions for managing networks and
their security using network traffic are based on UAA (User Activity Analysis). DLTs (Deep
Learning Techniques) have been recently used in network traffic analysis for better performances.
These previously suggested techniques for network traffic analysis typically need voluminous
information on network usages. Hence, this work proposes OFedeMWOUAA (optimal federated
learning-based UAA technique with Meadow Wolf Optimisation) and DNN (deep Neuron
Networks) for minimizing risks of data leakages in MWNs (Mobile Wireless Networks). In the
proposed OFedeMWOUAA, the need to submit data to cloud servers does not arise because it trains
DLTs locally and only uploads model gradients or knowledge weights. The OFedeMWOUAA
approach effectively decreases dangers to data privacies with very minor performance losses in
simulations
Estimation of Social Distance for COVID19 Prevention using K-Nearest Neighbor Algorithm through deep learning
Coronavirus disease has a crisis with high spread
throughout the world during the COVID19 pandemic period.
This disease can be easily spread to a group of people and
increase the spread. Since it is a worldly disease and not plenty
of vaccines available, social distancing is the only best approach
to defend against the pandemic situation. All the affected
countries' governments declared locked-down to implement
social distancing. This social separation and persons not being
in a mass group can slow down the spread of COVID19. It
reduces the physical contact between infected persons and
normal healthy persons. Almost every health organization tells
that to follow social distancing people should maintain at least 6
feet of distance from each other. This research proposes a deep
learning approach for social distancing which is developed for
tracking and detecting people who are in indoor as well as
outdoor scenarios using YOLO V3 video analytic technique.
This approach focuses to inspect whether the people are
maintaining social distancing in many areas, using surveillance
video with measuring the distance in real-time performance.
Most of the early studies of detecting social distance monitoring
were based on GPS for tracking the movements of people where
the signals could be lost. On the other hand, some countries use
drones to detect large gatherings of people who cannot have a
clear view at night times [10]. In the future, the proposed system
can be used fully for detecting threats in the public crowded or
it can detect any person affected by critical situations (ie
fainting, Cordia arrest) or planting the crops in the forms evenly
with a uniform measurement. This proposal could be used in
many fields like crowd analysis, autonomous vehicles, and
human action recognition and could help the government
authorities to redesign the public place layout and take
precautionary action in the risk zones. This system analyses the
social distancing of people by calculating the distance between
people to slow downing the spread of the COVID 19 virus
