Data interoperability and privacy schemes in healthcare data using Blockchain technology
Abstract. Electronic Health/Medical Records (EHR/EMR) lay the foundation for securely maintaining medical records. The traditional EHR systems are not effectively managed data manipulation, delayed communication, trustless data storage, data cooperation, and distribution.
Blockchain technology can play a major role in healthcare cases. This is because it uses decentralized distributed ledgers to securely manage all parties within the network. It also handles individual data through smart contracts, which can be pre-programmed by the patient for access and maintenance of healthcare data.
This thesis focuses on exploring the blockchain in digital healthcare services such as Electronic Health/Medical Records (EHR/EMR). Blockchain-based implementations of Ethereum allow patients to store their medical data with smart contracts that can perform activities such as Registration, Data Append, and Data Retrieve. The challenges faced during the implementation of blockchain protocols are discussed and analyzed in the scope of finding sustainable solutions to develop secure and reliable operation

UNSUPERVISED CHANGE DETECTION FOR MULTISPECTRAL IMAGES
This paper presents a novel approach to unsupervised change detection in multispectral remote-sensing images. The proposed approach aims at extracting the change information by jointly analyzing the spectral channels of multitemporal images without any training data. This is accomplished by using a selective Bayesian thresholding for deriving a pseudo training set that is necessary for initializing an adequately defined binary semisupervised support vector machine (S3VM) classifier. Starting from these initial seeds, the S3VM performs change detection in the original multitemporal feature space by gradually considering unlabeled patterns in the definition of the decision boundary between changed and unchanged pixels according to a semisupervised learning algorithm. The values of the classifier parameters are then defined according to a novel unsupervised model-selection technique based on a similarity measure between change-detection maps obtained with different settings
Design of a Partial Resonant Inverter for solar photovoltaic applications
This paper presents a solar-powered Partial Resonant Inverter (PRI) interfaced with an asymmetrical cascaded nine-level inverter. The DC input of the proposed system is obtained using Solar Photovoltaic (SPV) panel. The input DC sources fed to the asymmetrical cascaded nine-level inverter are in the ratio of 1:3. The step modulated nine-level inverter works with a precalculated switching angle for a fixed modulation of 0.7. Compared to the conventional 50βHz inverter and the multi-output transformer design, the proposed system is more compact because of the high-frequency AC link. The PRI ensures Zero Voltage Switching (ZVS) and reduces the switching losses. The proposed scheme has been validated in the MATLAB/ SIMULINK environment and an experimental prototype is built in the laboratory. Based on the investigations the Selective Harmonic Elimination (SHE) method gives superior performance when compared to the Optimal Harmonic Stepped Modulation (OHSM) method. From the results and comparative analysis, the proposed system uses fewer switches to obtain the nine-level output, uses the PRI setup with the multioutput transformer to make the design compact and improves the power quality of the system
ANDROID - ARM BASED SWITCH CONTROL USING SMART PHONE
The main idea behind this proposal is to provide an ease off access to the user by providing full control over his/her entire home. Due to modern city life we never find time to check any of our electric appliances, switches, thermostats, air conditioners and so on, whether they are regularly switched off when not in use. This results in Energy wastage, security risk, and eventually leads to stress. In our method we suggest an ease off method by using an Android phone with minimal power specifications
Histomorphological and clinicopathological correlates of reflux esophagitis
Background: Inflammatory lesions of the esophagus are major concerns to patients who visit our Medical Out Patient Department (OPD) on a regular basis. Endoscopic examination, with histopathological confirmation is the diagnostic modality employed in many centers. Endoscopic appearance is characteristic, and so are histomorphological findings. In our study we have analyzed the clinical, endoscopic and histomorphological findings of various types of esophagitis. This will help us to arrive at a correct diagnosis to initiate appropriate therapy.Methods: We included 141 cases of esophagitis reported in Sri Ramachandra Institute of Higher Education and Research from January 2016 to December 2020 in our study, mostly the ones which came as biopsy samples in histopathology section. Slides were reviewed, various histological features, clinical and endoscopic findings were correlated. Microsoft excel was used for the calculation of results.Results: Reflux esophagitis was most commonly seen in male patients (64%), between 40-60 years (35%) of age with presenting complaints of heart burn and clinical diagnosis of reflux esophagitis. Classic histological feature for the diagnosis of reflux esophagitis was epithelial hyperplasia noted in 89% male and 86% female patients, followed by increased basal cell thickness noted in 66% male and 55% female patients.Conclusions: Accurate diagnosis of reflux esophagitis is mainly based on histomorphological features. Capillaries in epithelium and basal cell hyperplasia along with history and endoscopic appearance to be considered for the diagnosis of reflux esophagitis
Proneo: Large File Transfer using Webworkers and Cloud Services
Cloud computing is a term, which involves virtualization, distributed computing, networking, and web services. Efficient data transfer among the cloud server and client. Cloud storage enables users to remotely store and retrieve their data. In previous work, the data are stored in the cloud using dynamic data operation with computation which makes the user need to make a copy for further updating and verification of the data loss. The objective of our project is to propose the partitioning method & web workers for the data storage which avoids the local copy at the user side. The cryptography technologies offer encryption and decryption of the data and user authentication information to protect it from the unauthorized user or attacker. MD5 based file encryption system for exchanging information or data is included in this model. This ensures secure authentication system and hiding information from others. The Cloud server allows user to store their data on a cloud without worrying about correctness & integrity of data.

Population dynamics and stock assessment of Delegoa threadfin bream, Nemipterus bipunctatus (Nemipteridae), from the Wadge Bank, South India
Fishery, population characteristics and stock estimates of Nemipterus bipunctatus were studied during June 2015 to May 2016 from Wadge Bank, South India. This region is characterised by rich biodiversity and has a conducive influence of the Indian Ocean and Arabian Sea. The asymptotic length (L?), growth coefficient (K) and arbitrary origin of growth (t0) were estimated as 30.5 cm, 0.85/year and 0.18 respectively. The mortality parameters, total mortality rate (Z), fishing mortality rate and natural mortality rate (M) were estimated as 2.20, 0.95 and 1.25 respectively. Exploitation ratio (E) was found to be 0.57 which showed marginal over exploitation of the species at Wadge Bank. This species has two recruitment seasons, one major season from October to December and another minor season in August. The length structured Virtual population analysis revealed heavy fishing pressure on the length group 24 to 28 cm and hence the delegoa threadfin bream was not found to suffer due to recruitment overfishing in Wadge Bank. Estimated total stock, Maximum Sustainable Yield (MSY) and annual catch were 5625.9348 tonnes, 1935.321t, 2419.152t respectively. Present level of Exploitation rate (U) and Exploitation ratio (F/Z) were estimated to be 0.43 and 0.57 respectively. The study infers the cod end mesh size of the trawls operated at Wadge Bank coast has to be increase from 10 to 25 mm to increase the yield per recruit, the effort could also be maintained as the exploitation ratio of 0.50 to have maximum yield per recruit. The study suggests reducing the present level of effort by 8 percent may be needed to sustain the stock of N. bipunctatus in Wadge Bank, South Indi
Study of characteristics of Al + 5 wt.% TiOβ + 6 wt.% Gr hybrid p/m composite powders prepared by ball milling process
This paper is an attempt to understand the characteristics of Al + TiOβ + Gr hybrid ball
milled composite powders, which is anticipated to have large application in the near future.
Aluminium with titanium dioxide (TiOβ) and graphite (Gr) powders was ball milled in
order to yield the composition like: Al + 0% TiOβ, Al + 5% TiOβ, Al + 5% TiOβ + 2% Gr,
Al + 5% TiOβ + 4% Gr and Al + 5% TiOβ + 6% Gr. From the X-Ray diffraction analysis
of the milled powders, the grain size, lattice space, lattice constant, stress, strain, dislocation
density and unit cell volume were calculated. Compressibility was performed in a
hardened steel die at pressures between 100 to 500 MPa to determine Al with 5 wt.% TiOβ
and 2 & 4 wt.% of Gr powder mixtures. For understanding of compaction behavior of aluminum
based hybrid composites reinforced with TiOβ and Gr particles under various
applied pressure conditions, experimental research has been made using several powder
compaction equations. Microstructure analysis for Al + 5% TiOβ + 6% Gr composite has
been reported.ΠΠΈΠ²ΡΠ°Π»ΠΈ Ρ
