VLSI Implementation of Block Error Correction Coding Techniques

Communication Engineering has become the most vital field of Engineering in today’s life. The world is dreaded to think beyond any communication gadgets. Data communication basically involves transfers of data from one place to another or from one point of time to another. Error may be introduced by the channel which makes data unreliable for user. Hence we need different error detection and error correction schemes. In the present work, we perform the comparative study between different FECs like Turbo codes, Reed-Solomon codes and LPDC codes. But among all these we find Reed Solomon to be most efficient for data communication because of low coding complexity and high coding rate. The RS codes are non-binary, linear and cyclic codes used for burst error correction. They are used in numerous applications like CDs, DVDs and deep space communication. We simulate RS Encoder and RS Decoder for double error correcting RS (7, 3) code. Then we implement RS (255,239) code in VHDL. In RS (255,239) code, each data symbol consists of 8 bits which is quite practical as most of the data transfer is done in terms of bytes. The implementation has been done in the most efficient algorithms to optimize the design in terms of space utilization and latency of the code. The behavioral simulation has been carried out for each block and for the whole design also. Finally, the FPGA utilization and clock cycles needed are analyzed and compared with the already developed designs

Online Platforms for Teaching-Learning in View of COVID – 2019

In almost all countries, classroom teaching has been suspended from mid March 2020 and currently no fresh dates have been announced by Governments to start the date. In view of this, almost all educational institutions in India are offering a variety of alternative teaching learning platforms to their students, whether Government run Institutions or privately run Institutions. The Institutions also conducted or planning to conduct their internal or final examinations through various platforms. In this paper, a number of online options for teaching and evaluation are discussed. The study is limited to India and discussion of software based platforms, whether web based or mobile apps based are considered. The research is limited to higher education sector specifically in undergraduate engineering education

Life prediction model for creep-fatigue interaction of P92 advanced grade martensitic steel

Creep-fatigue interaction has been identified as a possible degradation mechanism leading to failure of power plant components such as thick sections header pipe etc. During startup/shutdown processes, severe thermal gradient sets in across the thickness between the inside and outside of the component. Fluctuation of demand also results in alternation of such operation results in thermal gradient. Both the above mentioned situation leads to hold time fatigue kind of situation. P92 (9Cr-1Mo-2W) martensitic steel is widely used for the manufacturing of header pipes and is subjected to creep-fatigue loading condition. The aim behind the present study is to verify an existing unified viscoplasticity constitutive model, proposed by Choboche. This model includes combined isotropic hardening and kinematic hardening with a viscoplastic flow rule for time-dependent effects. For this study isothermal, uniaxial, fully reversed, strain controlled low cycle fatigue and stress relaxation fatigue tests at various hold time duration at maximum/minimum strain amplitude were conducted on P92 material at 600¢ªC. The P92 material in the present study has been recognized as a cyclic softening material Here the initial value of material constants associated with Chaboche model has been determined from the first cycle stress-strain data, the maximum stress evolution during tests and the stress relaxation data. Then, the initial constants need to be optimized using a least-squares optimization algorithm in order to improve the general fit of the model to experimental data

SIMULTANEOUS ESTIMATION OF PROPAFENONE AND ITS TWO METABOLITES IN HUMAN PLASMA BY LIQUID CHROMATOGRAPHY/TANDEM MASS SPECTROMETRY LC-MS/MS

Objective: A simple, sensitive and rapid performance liquid chromatography/positive ion electrospray tandem mass spectrometry method was to be developed and validated for quantification of propafenone (PPF) and its two major metabolite 5-hydroxy propafenone (5-OHP) and N-depropyl propafenone (NDP) in human plasma.Methods: Liquid-liquid extraction (LLE) with ethyl acetate was used of extraction of plasma samples. The analytes were separated using an isocratic mixture of 0.1% formic acid/acetonitrile (20:80 v/v) on a reversed-phase column Hypurity Advance C18 50 x2.1 mm, 5µ and analysed by mass spectrometry in the multiple reaction monitoring mode using the respective [M+H] Ions. The m/z was 342.20/116.10 for propafenone, m/z 299.80/74.10 for N depropyl propafenone and m/z 358.30/98.10 for 5-hydroxy propfenone along with m/z 409.2/238.0 for Amlodipine as internal standard respectively.Results: The method had a short chromatographic run time of 1.5 min. The method exhibited a linear dynamic range over 5.11 to 1000.73 ng/ml for propafenone, 0.51 to 100.06 ng/ml for N-depropyl propafenone and 5.11 to 1001.64 ng/ml for 5-hydroxy propafenone respectively, in human plasma.Conclusion: The validated method has been successfully used to analyze human plasma samples for application in pharmacokinetics, bioavailability and bioequivalence studies
