Abstract

Let $T$ be a tree with no degree 2 vertices and $L(T)=\{l_1,\ldots,l_r\}, r \geq 2$ denote the set of leaves in $T$. An Halin graph $G$ is a graph obtained from $T$ such that $V(G)=V(T)$ and $E(G)=E(T) \cup \{\{l_i,l_{i+1}\} ~|~ 1 \leq i \leq r-1\} \cup \{l_1,l_r\}$. In this paper, we investigate combinatorial problems such as, testing whether a given graph is Halin or not, chromatic bounds, an algorithm to color Halin graphs with the minimum number of colors. Further, we present polynomial-time algorithms for testing and coloring problems.

9. The lives of the underprivileged people found in Tamil literature

Abstract

It is an undetermined rule that all beings that have arisen in this world must be respected equally. There is no one who has adhered to such a canon. Inequality between every living being that can live in this world is a fundamental matter of nature. The beginning of inequality is the definition that he should and should not do even the most common activities in the world. We can identify such a preliminary difference in the Tolkappiyam itself. People like errand runner and Panar, who works for the life of others more than their own needs, can be considered grassroots people. The focus of this article is on examining the atrocities faced by these underprivileged people from time to time, the obstacles they faced in their daily way of life, and the rights denied by birth through the literature that has emerged from time to time. Even in the Sangam literature, which can be portrayed as the golden age of the Tamils, there are records of the fact that the people of the lower strata were untouchables and should not be seen. Similarly, moral literature also highlights the sufferings of downtrodden people. Whoever sees inequality in the world, God does not see it. But even in devotional literature, there are caste-based devotees. From Minor Literature to Modern Literature, the life of the downtrodden is seen as a place of suffering and misery. Thus, this article proves that the lives of the lower classes are the same in the literature that reflects the society from the Sangam period to the present day.

Abstract

Corona Virus Disease 2019-Covid-19 is one of the most severe and acute disease that affected the economy and wellbeing of the globe. The Covid-19 diagnostic method was carried out in two broad categories: RT-PCR in the laboratory and chest radiography (X-ray and CT scan). Recently, the rapid researches have pioneered to collaborate the healthcare with Artificial Intelligence (AI). With focus of AI, the huge studies on going in the COVID-19 disease for obtaining the ultimate accuracy results and diagnosis the disease at an early time. This survey provides systematic review and meta-analysis with highlighting novelty for the future research directions and mostly concentrated on analysis work of previous models on classification of dataset which is containing Covid-19, Pneumonia, SARS-COV2, and Normal lungs of CT (Computerized Tomography) scan images using the techniques of Deep Learning.

13. Effect of ultrasonication and enzyme activity on dye uptake of cationised cotton fabric.

Author

Subathra, S., Vinothini, R., Sowmiya, S., Hemamalini, T., and Dev, V. R. Giri

Abstract

To eliminate the usage of salt, salt-free reactive dyeing using CHPTAC (3-Chloro-2-hydroxypropyl trimethylammonium chloride) has been proposed. Studies have shown promising results, such as better dye shade attainment and less effluent load compared to conventional methods. In this work, to improve the effective utilisation of CHPTAC, the cotton fabric has been treated with cellulase enzyme and the application of CHPTAC is carried out using the ultrasonication technique. The samples are then characterised for colour parameters and it is found that the enzymatic treatment and ultrasonication lead to improve the dye uptake, as the interaction of CHPTAC with the fabric becomes better.

Abstract

This proposed paper is to model and simulate the sensor less control of Brushless DC motor with four switch three phase inverter. Here, a new structure of three phase inverter with reduced number of switches i.e. four switch for BLDC drive is introduced to reduce the switching losses that occur in the six switch method and eliminate the mechanical commutation. Conventionally used hall sensors for position detection increase the size of the motor and are temperature sensitive since they are mounted inside. So sensor is eliminated and the back emf method is adopted for switching. The zero crossing point can be detected and it is used to commutate a motor thereby increasing the overall efficiency.

Abstract

To evaluate the effectiveness of structured teaching programme regarding weaning practices among Primipara mothers. To determine the association on weaning practices with the selected demographic variables. The convenience sampling technique with the sample of 53 primipara mothers and self structured questionnaire to assess the pre-test and post-test knowledge of mothers on weaning practices. The structured teaching programme to assessing the level of knowledge of primipara mothers on weaning practices. The level of significance selected was p<0.05. The data collection tools was validated and reliability was established. The data were collected by self structured questionnaire. The collected data was tabulated and analyzed. Descriptive and inferential statistics were used. The pre test mean value is 8 and post test mean value is 97 and the pretest standard deviation is 2.227 and post test standard deviation is 336.4 .The study showed that pretest on 1.88 % of primipara mothers had adequate knowledge, 58.4% of primipara mothers had moderate knowledge, 39.6% of the primipara mothers had inadequate knowledge and post test on 92.4% of primipara mothers had adequate knowledge, 7.54 % of primipara mothers had moderate knowledge, 0% of the primipara mothers had inadequate knowledge on weaning practices and there was a significant association of the knowledge with demographic variables.

23. Feature Extraction, Risky Classifications and Fault Diagnosis on Rolling Bearings of EEG Signals Denoised using Stationary Wavelet Transform of Patient Monitoring and IoT

Author

Abstract

Background: One of the primary causes of sleep disorders, depth of anesthesia, coma, encephalopathy’s and brain death in the world is epilepsy. EEG is most often used to diagnose epilepsy which causes the abnormalities in EEG readings. Different high-resolution anatomical imaging techniques are used to detect these abnormalities like MRI, PET, CT, etc. Methods: SWT method will be an enhanced system from wavelet transform. It may be fit for the signal for time-invariant on the break down also enhance those force of indicator denoising. SWT additionally employs upsampled technique at every level of decay for those signs. The decay of SWT produces the coefficients from claiming close estimation and points in the same length. The DWT will be actualized by a channel bank that decomposes those indicators over progressive coarser approximations. The output of the low pass and high pass filter coefficients is decomposed to the next level and further proceeds up to N levels. The yield of the wavelet decay may be that close estimation and the point of interest coefficients which would get to each level of decay. This system consists of five main processing steps: acquisition, pre-processing, feature extraction, feature selection and classification. Results: This paper overviews some of the current state-of-the-art IOT systems and presents the statistical-based algorithm used for each processing step. Conclusion: This paper also provides a comparison of the performance of the existing approaches.
