The development of the modern power system has led to an increasing complexity in study systems, and also presents new challenges stability, particular, aspects transient stability small-signal stability.Transient control plays a significant role ensuring stable operation systems event large disturbances faults, is thus area research.This paper investigates improvement two-area system, using UPFC (Unified Power Flow Controller) which effective FACTS (Flexible AC Transmission System) device...
Mobile ad hoc network (MANET) is a collection of autonomous mobile nodes forming an without fixed infrastructure. Dynamic topology property MANET may degrade the performance network. However, multipath selection great challenging task to improve lifetime. We proposed energy‐aware routing scheme based on particle swarm optimization (EMPSO) that uses continuous time recurrent neural (CTRNN) solve problems. CTRNN finds optimal loop‐free paths link disjoint in MANET. The used as optimum path...
Abstract Chest X-rays are the most economically viable diagnostic imaging test for active pulmonary tuberculosis screening despite high sensitivity and low specificity when interpreted by clinicians or radiologists. Computer aided detection (CAD) algorithms, especially convolution based deep learning architecture, have been proposed to facilitate automation of radiography modalities. Deep algorithms found success in classifying various abnormalities lung using chest X-ray. We fine-tuned,...
Abstract Background The mucus from fish and gastropods contains a wide range of bioactive molecules with biomedical properties. were collected Oragadam lake, Kanchipuram district, Tamil Nadu, India. In this study, we wanted to examine the anticancer potential mucus. biochemical components crude screened. Results analysis showed that Anabas testudineus Pila virens contained high level carbohydrates (2.8 1.5 mg/ml), Channa striata lipids (0.9 Helix aspersa protein (1.3 mg/ml). results...
The solution of author’s mathematical model Magnetohydrodynamics (MHD) flow a Casson fluid is discussed. given nonlinear partial differential equations are converted into ordinary using similarity transformations. simple and closed form analytical expression for concentration profiles provided. compatibility results with simulation can be observed from the graphs table presented.
Tuberculosis (TB) mortality rose during the COVID-19 pandemic, as did food insecurity worldwide. Undernourished individuals are at increased risk for incident TB disease and mortality. This study examines impact of COVID lockdowns on security households with in Southern India. In-depth interviews focus group discussions were conducted household contacts enrolled a nutritional intervention study, Puducherry Tamil Nadu (2018–2024), which provided persons six-month intervention. During...
A BSTRACT Primary synovial sarcoma (SS) is an uncommon lung tumor. The thigh, knee, ankle, foot, and upper extremities are the most often reported locations of origin. Sarcomas barely make up 0.1–0.5% cases. This report presents two cases primary pulmonary SS. Typically, tumor manifests at a younger age. When diagnosis SS confirmed by clinical, histological, immunohistochemical examinations, molecular testing not necessary. Instead, radiological histopathological findings necessary for Early...
Flexible alternating current transmission systems (FACTS) technology opens up new opportunities for controlling power and enhancing the usable capacity of present, as well upgraded lines.The Unified Power Flow Controller (UPFC) is a second generation FACTS device which enables independent control active reactive besides improving reliability quality supply.This paper describes real flow through line by placing UPFC at sending end an electrical system.The performance compared with that other...
Bronchial asthma is a common chronic inflammatory airway disease diagnosed and based on symptomatic history Pulmonary Function Tests (PFT). Fractional exhaled Nitric Oxide (FeNO) exclusively non-invasive biomarker of on-going eosinophilic inflammation which remains unpredictable only with PFTs. FeNO measurement recommended in predicting severity Inhaled Corticosteroid (ICS) response but further research required to understand its clinical utility agreement current recommendations specific...
Cloud computing evolve as a cost effective business model for IT companies to focus on their core without perturbing infrastructure related issues.Hence, major firms and Small & Medium Enterprises (SME) are adopting cloud services rental basis from providers.Cloud Service level agreements (SLA) act key liaison between consumers providers renting Anything (AaaS).Design of such an agreement must aim greater profit well assured availability consumers.However in reality, SLA is not satisfying...
Contrast enhancement of an image can efficiently performed by histogram equalization. However, this method tends to introduce unnecessary visual deterioration such as saturation effect. One the solutions overcome weakness is preserving mean brightness input inside output image. This paper proposes a new equalization called contrast stretching recursively separated (CSRSHE), for preservation and enhancement. algorithm applies two stage approach: 1) A intensity assigned each pixel according...
Zygomycosis refers to a group of disorders caused by filamentous fungi in the class Zygomycetes. This is subdivided into 2 orders, Mucorales and Entomophthorales, both implicated human disease. The majority infections are order; hence, terms
In this paper, an enhanced Z-source inverter (ZSI) is introduced for controlling the speed of permanent magnet brushless DC motor (PMBLDCM) drive. It extension conventional ZSI and elements used in circuit are same as those ZSI, except that position Inverter Bridge diode would be exchanged from classical diagram. This avoids startup path inrush current hence reduces improves efficiency. Different modes studied with PMBLDCM. The voltage polarity capacitors proposed input polarity....
Background: The national tuberculosis (TB) programme in India recommends screening all pregnant women for TB, but this is rarely implemented. We carried out systematic TB among attending the antenatal clinic of a tertiary care hospital Puducherry, South India, during February to April 2018.Objective: To assess number screened and (proportion) with presumptive active understand potential implementation from healthcare providers' perspective.Methods: conducted mixed-methods study. quantitative...
Lung cancer is the most common malignancy in both gender. Early diagnosis needed to reduce morbidity and mortality. There a debate about accurate investigating modality for of lung cancer.It retrospective cohort analysis determine whether an approach combined contrast-enhanced computed tomography (CECT) thorax with bronchoscopy method has higher sensitivity specificity than CECT sputum cytology method. Records patients who had visited hospital within last 6 months were retrospectively...
Background On December 21, 2019, a pneumonia-like outbreak of an unknown cause or origin was found to be emerging in Wuhan, China. In India, the first case COVID-19 Kerala and then started spread all over India. Most infected people have recovered from disease, but some patients were symptoms at post-discharge follow-up. Although there are many studies on signs during hospital stays, is scarcity information regarding post-COVID-19 manifestations. The purpose this study analyze clinical...
