- When Innovation meets Compassion: Dr Sunitha’s Noble Initiative December 21, 2022
The Directorate of Entrepreneurship and Innovation steps forth with yet another brave initiative from Dr Sunitha K A, Associate Professor, the Department of Electronics and Communication Engineering. Dr Sunitha had envisioned a dream to empower patients suffering from ailments that require sustained medical assistance with a specially designed convertible wheelchair that can aid the patients in mobility and self-help. In association with Hatchlab Research Centre, Dr Sunitha has initiated a health-tech startup exclusively for patients who cannot move their bodies due to several medical conditions and to raise awareness of the continuing rise of similar cases in today’s society.
Dr Sunitha says, “The main challenge of the patient is to perform the basic movements like coming out of the bed and to sit in the wheelchair (and vice-versa), and it is almost impossible for a patient to do this simple act without external support of a person or a nurse. We have listed several such scenarios and cases where our specially designed wheelchair can be converted into a bed and can be easily controlled by the patient itself. Apart from that, all the necessary inputs like the urine levels in the drop-bag, pulse rate, emergency indicated, oxygen levels and several other parameters are well integrated into the system itself which displays in the dashboard and is communicated to the stakeholders.”
The prototype for the convertible wheelchair has been successfully tested and appreciated by doctors and experts in Chennai. With the help of Hatchlab Research Centre, the prime focus for the next few months is to create a completely functional prototype. The innovative venture plans to recreate the fully functional prototype, seed funding and round one funding from the investors, followed by large-scale production. Several multinational design patents for the product have already been filed by Dr Sunitha, and the next stage of the cohort is the commercialisation of the product.

- Successful Food-Tech Venture hoists Jaswanth to Newer Heights! December 19, 2022
“The best way to predict the future is to create it”. Jaswanth Sai has proved to be a living and breathing manifestation of this quote with his determination and hard work. The Directorate of Entrepreneurship and Innovation is pleased to announce that Jaswanth Sai Idupulapati, a 3rd year BBA student, has successfully started his own food-tech company, Open Cafe, a cloud kitchen enterprise. Cloud kitchens are centralised, licensed commercial food production facilities where one to dozens of restaurants rent space to prepare delivery-optimised menu items. Jaswanth, an enthusiastic student of the Hatchlab Research Centre had started his business with an investment of Rs. 5000/- and today his turnover is more than 20L per month for a business that was started just three months ago!
“We invested Rs. 5000 and brought a van full of biriyani outside the main gate of our university. Hours passed and not a single sale happened. Those moments were not only depressing but also terribly demotivating. But as a leader, I had to rise up! We immediately changed the pricing strategy and shared the same via WhatsApp groups. In the next 45 minutes, we were left with empty vessels and a handful of cash. Profit was less; the learning and our confidence levels were mountain high,” Jaswanth excitedly mentioned about his first day of business.
As of now, Open Cafe caters to more than 1000+ students from SRM AP and VITAP, with quality food items that are delivered with a caption – 15 minutes delivery. Jaswanth has 15 employees and a big renovated kitchen, generating employment and thousands of satisfied customers.
His dedication and hardcore willpower allowed the materialisation of his idea into reality. Congratulations to Jaswanth Sai for his astonishing achievement!

Abstract
Soil and groundwater contamination is caused by improper waste disposal practices and accidental spills, posing a threat to public health and the environment. It is imperative to assess and remediate these contaminated sites to protect public health and the environment as well as to assure sustainable development. Site remediation is inherently complex due to the many variables involved, such as contamination chemistry, fate and transport, geology, and hydrogeology. The selection of remediation method also depends on the contaminant type and distribution and subsurface soil and groundwater conditions. Depending on the type of remediation method, many systems and operating variables can affect the remedial efficiency. The design and implementation of site remediation can be expensive, time-consuming, and may require much human effort. Emerging technologies such as Artificial Intelligence, Machine Learning, and Deep Learning have the potential to make site remediation cost-effective with reduced human effort. This study provides a brief overview of these emerging technologies and presents case studies demonstrating how these technologies can help contaminated site remediation decisions.
- EEE Students Visited Dr Narla Thatharao Thermal Power Station (NTTPS) December 16, 2022
Industrial visit is an efficient learning strategy that nullifies the distance between academia and industry. Students and faculty of the Department of Electrical and Electronics Engineering visited Dr Narla Thatharao Thermal Power Station (NTTPS) on November 21, 2022. The objective of the visit was to give an overview of the Thermal Power plant, which is a coal-based power plant where coal is transported from coal mines to the power plant by railway in wagons or a merry-go-round system.The state-of-the-art construction and technologies amazed the students as they experienced an insightful industrial visit that exposed them to the actual working of a thermal power plant while enforcing their theoretical knowledge of Power Systems, Control Systems and Electrical Machines. Students from semesters one to four participated in the industry visit. Dr Somesh Vinayak Tewari, Dr Shubh Lakshmi, Dr Bhamidi Lokeshgupta, Dr Ramanjaneya Reddy U, and Dr Venkata Ramireddy Y were the faculty who accompanied the students.
A Detailed Account of the Industry Visit
Coal is unloaded from the wagons using wagon tippler units to a moving underground conveyor belt. This coal from the mines is of no uniform size. So, it is taken to the Crusher house and crushed to a size of 20 mm. From the crusher house, the coal is either stored in dead storage, which serves as coal supply in case of coal supply bottleneck or to live storage in the raw coal bunker in the boiler house. Raw coal from the raw coal bunker is supplied to the Coal Mills by a Raw Coal Feeder. The Coal Mills or pulverizer pulverizes the coal. The powdered coal from the coal mills is carried to the boiler in coal pipes by high-pressure hot air. The pulverized coal air mixture is burnt in the boiler in the combustion zone.Generally, in modern boilers, a tangential firing system is used where the coal nozzles/guns form a tangent to a circle. The temperature in the fireball is of the order of 1300˚C. The boiler is a water tube boiler hanging from the top. Water is converted to steam in the boiler, and steam is separated from water in the boiler Drum. The saturated steam from the boiler drum is taken to the Low-Temperature Superheater, Platen Superheater and Final Superheater, respectively, for superheating. The superheated steam from the final superheater is taken to the High-Pressure Steam Turbine (HPT). In the HPT, the steam pressure is utilised to rotate the turbine, and the resultant is rotational energy. From the HPT, the outcoming steam is taken to the Reheater in the boiler to increase its temperature as the steam becomes wet at the HPT outlet. After reheating, this steam is taken to the Intermediate Pressure Turbine (IPT) and then to the Low-Pressure Turbine (LPT). The outlet of the LPT is sent to the condenser for condensing back to water by a cooling water system. This condensed water is collected in the Hot well and sent to the boiler in a closed cycle. The rotational energy imparted to the turbine by high-pressure steam is converted to electrical energy in the Generator.

SRM AP proudly congratulates Dr Anil K Suresh, Associate Professor, Department of Biological Sciences and his cohort of research scholars for their rare achievement of having their paper featured in the prestigious weekly news magazine Chemical and Engineering News (ACS-C&EN). The news article titled “This catalyst is a Golden Egg“, edited by Prachi Patel highlights the innovative research conducted by Dr Anil K Suresh and his team on developing a low-cost, sustainable catalyst by infusing eggshells with gold nanoparticles that can be reused and eventually recycled.
The research paper titled Sustainable Bio-Engineering of Gold structured Wide-Area Supported Catalyst for Hand-Recyclable Ultra-Efficient Heterogeneous Catalysis (ACS Appl. Mater. Interfaces 2022, DOI: 10.1021/acsami.2c13564) highlights the team’s breakthrough advance in impregnating eggshells with gold nanoparticles to develop a cheap, and reusable ‘mega catalyst’. The research has used the robust “mega catalyst” to detoxify dye waste and run other organic reactions by dropping the eggshell catalyst into reaction solutions.
Dr Suresh and colleagues dipped waste eggshells collected from restaurants in a suspension containing gold chloride for 6 hours. Consequently, the amino acids on the shells reduced the gold ions to form crystalline gold nanoparticles. Dr Suresh attested this method to be one of the simplest syntheses of a supported catalyst that was ever reported. He emphasised that he and his colleagues have also grafted catalytic silver and copper oxide on eggshells and are now working on methods to do this for platinum and palladium.
SRM University-AP manifests pioneering advancement in innovative domains of research in the field of science and technology. The breakthrough research by Dr Anil K Suresh and his research team is of outstanding achievement and incredible addition to the institution’s laurels in the field of translational research.

Breast cancer (BC) is one of the most common types of cancer among women with a high mortality rate. Histopathological analysis facilitates the detection and diagnosis of BC but is a highly time-consuming specialised task, dependent on the experience of the pathologists. Hence, there is a dire need for computer-assisted diagnosis (CAD) to relieve the workload on pathologists. Dr Sudhakar Tummala, Assistant Professor, Department of Electronics and Communication Engineering, has conducted breakthrough research on this domain in his paper titled BreaST-Net: Multi-Class Classification of Breast Cancer from Histopathological Images Using Ensemble of Swin Transformers published in the Q1 Journal Mathematics, having an Impact Factor of 2.6.
Abstract
Breast cancer (BC) is one of the deadly forms of cancer and a major cause of female mortality worldwide. The standard imaging procedures for screening BC involve mammography and ultrasonography. However, these imaging procedures cannot differentiate subtypes of benign and malignant cancers. Therefore, histopathology images could provide better sensitivity toward benign and malignant cancer subtypes. Recently, vision transformers are gaining attention in medical imaging due to their success in various computer vision tasks. Swin transformer (SwinT) is a variant of vision transformer that works on the concept of non-overlapping shifted windows and is a proven method for various vision detection tasks. Hence, in this study, we have investigated the ability of an ensemble of SwinTs for the 2- class classification of benign vs. malignant and 8-class classification of four benign and four malignant subtypes, using an openly available BreaKHis dataset containing 7909 histopathology images acquired at different zoom factors of 40×, 100×, 200× and 400×. The ensemble of SwinTs (including tiny, small, base, and large) demonstrated an average test accuracy of 96.0% for the 8-class and 99.6% for the 2-class classification, outperforming all the previous works. Hence, an ensemble of SwinTs could identify BC subtypes using histopathological images and may lead to pathologist relief.
A brief summary of the research in layperson’s terms
Breast cancer (BC) is the second deadliest cancer after lung cancer, causing morbidity and mortality worldwide in the women population. Its incidence may increase by more than 50% by the year 2030 in the United States. The non-invasive diagnostic procedures for BC involve a physical examination and imaging techniques such as mammography, ultrasonography and magnetic resonance imaging. However, the physical examination may not detect it early, and Imaging procedures offer low sensitivity for a more comprehensive assessment of cancerous regions and identification of cancer subtypes. Histopathological imaging via breast biopsy, even though minimally invasive, may provide accurate identification of the cancer subtype and precise localization of the lesion. However, this manual examination by the pathologist could be tiresome and prone to errors. Therefore, automated methods for BC subtype classification are warranted.
Deep learning has revolutionised many areas in the last decade, including healthcare for various tasks such as accurate disease diagnosis, prognosis, and robotic-assisted surgery. There were studies based on deep convolutional neural networks (CNN) for detecting BC using the aforementioned imaging procedures. However, CNNs exhibit inherent inductive bias and are variant to translation, rotation, and location of the object of interest in the image. Therefore, image augmentation is generally applied while training CNN models, although the data augmentation may not provide expected variations in the training set. Hence, self-attention based deep learning models that are more robust towards the orientation and location of an object of interest in the image are rapidly growing.
SwinTs are an improved version of earlier vision transformer (ViT) architecture and are hierarchical vision transformers using shifted windows that work based on self-attention. For efficient modelling, self-attention within local windows was proposed and computed, and to evenly partition the image, the windows are arranged in a non-overlapping manner. The window-based self-attention has linear complexity and is scalable. However, the modelling power of window-based self-attention is limited because it lacks connections across windows. Therefore, a shifted window partitioning approach that alternates between the partitioning configurations in consecutive Swin transformer blocks was proposed to allow cross-window connections while maintaining the efficient computation of non-overlapping windows. The shifted window scheme in Swin transformers offers increased efficiency by restricting self- attention computation to local windows that are non-overlapping while also facilitating a cross-window connection. Overall, the SwinT network’s performance was superior to that of the standard ViTs.
Therefore, the paper analyses the ability of an ensemble of Swin transformer models (BreaST-Net) for the automated multi-class classification of BC by investigating histopathological images. The work dealt with both benign and malignant subtypes. Further, the benign cancer subtypes include fibroadenoma, tubular adenoma, phyllodes tumour, and adenosis. Whereas the malignant subtypes contain ductal carcinoma, papillary carcinoma, lobular carcinoma, and mucinous carcinoma.
Social implications of the research
Dr Sudhaker Tummala explains that the computer-aided subtyping of breast cancer from histopathology images using an ensemble of fine-tuned SwinT models can be an alternative to manual diagnoses, thereby reducing the burden on clinical pathologists.
Collaborations
- Prof. Seifedine Kadry, Department of Applied Data Science, Noroff University College, Kristiansand, Norway
- Dr Jungeun Kim, Division of Computer Science, Department of Software, Kongju National University, Korea
In the future, Dr Tummala will advance his research to add explainability to the ensemble model predictions and also to develop models that can work on fewer data samples.
