Necrotizing sialometaplasia of palate: a case report
Sowmya Krishna,Ramnarayan BK 대한구강악안면방사선학회 2011 Imaging Science in Dentistry Vol.41 No.1
Necrotizing sialometaplasia (NS) which mimics malignancy both clinically and histopathologically is an uncommon benign, self-limiting inflammatory disease of the mucus-secreting minor salivary glands. The lesion is believed to be the result of vascular ischemia that may be initiated by trauma. Till date, the diagnosis of NS remains a challenge. This report demonstrates a case of NS in a 73-year-old male patient who presented with an ulcerative lesion in his palate. He had a history of local trauma and was long-term user of salbutamol inhaler. An incisional biopsy was carried out and the diagnosis was established through history, clinical examination, histopathology using Hematoxylin and Eosin stain. The patient was given symptomatic treatment and the lesion healed in about 7 weeks.
Application of Quasi Infinite Horizon Nonlinear Model Predictive Control to Unstable Tank Reactor
Sowmya Gupta,Chinmay Rajhans 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.6
Ensuring asymptotic stability of nominal nonlinear model predictive control scheme is not a trivial task. Various approaches like terminal equality constraint, terminal inequality constraint and without terminal inequality constraint are available in the literature. Current paper details application of two novel approaches for the terminal set computation of discrete time quasi infinite horizon nonlinear model predictive control formulations around open loop unstable equilibrium condition. Case study used for demonstration is a standard continuous stirrer tank reactor system. Fundings are displayed without any noise case i.e., nominal case and for with input noise and state noise i.e., robust case. Studies validate and verify the asymptotic stability result. State trajectories for with noise case i.e., robust cases remained close to the trajectories in without noise case i.e., nominal case as per expectation (because of the bounded disturbances).
Human fall classification system for ceiling-mounted kinect depth images
Sowmya Kasturi,Kang-Hyun Jo 제어로봇시스템학회 2017 제어로봇시스템학회 국제학술대회 논문집 Vol.2017 No.10
The number of elderly people living alone has been considerably increased over the past few years. Hence the research regarding Ambient Assisted Living (AAL) systems has been given significant importance to improve the quality of life for them. Falls have become one of the major health concern among elders. Many fall detection and classifications methods are being developed to provide a reliable solution. The proposed system presents a vision based human fall classification method to discriminate falls from non-fall events. The depth images from a ceiling mounted Kinect camera are considered in the proposed system to preserve privacy, reduce the influence of occlusion and complex cluttered background. Human silhouettes are obtained after background subtraction and shape based features are extracted. A binary Support Vector Machine(SVM) classifier fed with these features is used to classify the fall events from non-fall events. The proposed method was tested on a publicly available dataset and classifies falls from other actions with an accuracy of 93.04%.
The Immune Landscape in Nonalcoholic Steatohepatitis
Sowmya Narayanan,Fionna A. Surette,Young S. Hahn 대한면역학회 2016 Immune Network Vol.16 No.3
The liver lies at the intersection of multiple metabolic pathways and consequently plays a central role in lipid metabolism. Pathological disturbances in hepatic lipid metabolism are characteristic of chronic metabolic diseases, such as obesity-mediated insulin resistance, which can result in nonalcoholic fatty liver disease (NAFLD). Tissue damage induced in NAFLD activates and recruits liver-resident and non-resident immune cells, resulting in nonalcoholic steatohepatitis (NASH). Importantly, NASH is associated with an increased risk of significant clinical sequelae such as cirrhosis, cardiovascular diseases, and malignancies. In this review, we describe the immunopathogenesis of NASH by defining the known functions of immune cells in the progression and resolution of disease.

Cost Minimization for Big Data Processing in Geo-Distributed Data Centres
T. Sai Raaga Sowmya 사단법인 미래융합기술연구학회 2016 아시아태평양융합연구교류논문지 Vol.2 No.4
Demand on big data is being increasing day by day and also increasing heavy burden on computation, storage and communication in data centres, which lead to considerable expenditure to data centre providers. So, cost minimization became an issue for the upcoming bid data.one of the main feature of bid data is coupling of data and computation as computation task. This can be done only when that corresponding is available for computation. Three tasks like data placement, task assignment and data movement influence the expense of data centres. In this paper we study how to minimize cost through joint optimization of these above three factors for big data service in geo distributes data centres. Here we propose 2-D Markov chain to describe time to complete a particular task with consideration of data transmission and computation to derive average task completion time in closed time. In addition, we here model the problem as mixed integer nonlinear programming and propose a solution to linearize it.

Objectives: This study is aimed to evaluate and compare the effect of moist heat fomentation therapy with ultrasound therapy in patients with the masticatory myalgia. Materials and Methods: The study was conducted on 42 patients with masticatory myalgia, dividing them into two groups; Group A (21 patients), received moist heat therapy and Group B (21 patients), received ultrasound therapy for seven effective days. Prior and after the treatment the numeric rating scale (NRS) and the electromyography (EMG) scores were recorded and compared. The observations were analyzed clinically and statistical support was taken to assess the NRS and EMG data. Results: Irrespective of the groups, patients testified a significant reduction in pain after the treatment. From the EMG readings; even though the standard deviation for each group was varied considerably, EMG recorded an improved muscle activity. Statistical analysis was used to assess and identify the best treatment methodology between the two modalities. Conclusion: From the statistical analysis, it is concluded that, though both the therapies had significantly reduced the symptomatic response, it is moist heat fomentation that improved muscle activity both statistically and clinically in comparison to ultrasound.
Heat transfer analysis of nanofluid flow in a channel with non-parallel walls
H. Berrehal,G. Sowmya 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.1
The aim of the current investigation is to explore the heat transfer of nanofluid flow in a channel with non-parallel walls. Two different nanoparticles, namely, Cu and Ag, with water as the base fluid are considered. The equations governing the flow are obtained using an appropriate similarity transform and solved analytically with the optimal homotopy asymptotic method (OHAM). Here, OHAM was first used to solve the problem to ensure a much more rapid convergence of the solution only after one iteration, with high efficiency. Comparative analysis was carried out to ensure the authenticity of the results. The effects of the involved parameters on fluid velocity, temperature, skin friction coefficient, and Nusselt number are presented in graphical and tabular forms with comprehensive discussions in this paper.
