    An exponential increase in number of attacks in IoT Networks makes it essential to formulate attack-level mitigation strategies. This paper proposes design of a scalable Kernel-level Forensic layer that assists in improving real-time evidence analysis performance to assist in efficient pattern analysis of the collected data samples. It has an inbuilt Temporal Blockchain Cache (TBC), which is refreshed after analysis of every set of evidences. The model uses a multidomain feature extraction engine that combines lightweight Fourier, Wavelet, Convolutional, Gabor, and Cosine feature sets that are selected by a stochastic Bacterial Foraging Optimizer (BFO) for identification of high variance features. The selected features are processed by an ensemble learning (EL) classifier that use low complexity classifiers reducing the energy consumption during analysis by 8.3% when compared with application-level forensic models. The model also showcased 3.5% higher accuracy, 4.9% higher precision, and 4.3% higher recall of attack-event identification when compared with standard forensic techniques. Due to kernel-level integration, the model is also able to reduce the delay needed for forensic analysis on different network types by 9.5%, thus making it useful for real-time & heterogenous network scenarios

    A Novel approach for optimization in Mathematical calculations using Vedic Mathematics Techniques

    Get PDF
    Vedic Mathematics is the name given to the ancient system of mathematics, or to be precise, a unique technique of calculations based on simple rules and principles with which any mathematical problem can be solved ā€“ be it arithmetic, algebra, geometry or trigonometry. The system is based on 16 Vedic sutras or aphorisms, which are actually word formulae describing natural ways of solving a whole range of mathematical problems. In this paper, we will be taking a few Vedic sutras. Akadhiken Purven (By one more than the one before), Nikhilam Navtashcharam Dashat (All from 9 and the last from 10) are two of them. NASA has adopted it fully in the realms of advanced robotics. Calculations that can be solved as quick as lightning are a great tool to adopt, but you wouldnā€™t want to teach it worldwide in the fear that you may churn out a generation of child geniuses that may threaten the intellectual status quo. The gift that the Hindus gave to the world, thousands of years ago, and that which is currently responsible for global silicon chip technology, was none other than the invention of zero and the use of the decimal point. We call our common numbers ā€œArabic Numeralsā€ but really they extend back to the Hindu concept of creation and were known as ā€œBinduā€ or Unity. All Vedic Maths is based on the understanding of Unity Consciousness which means they utilize processes or Number Bases that correspond to 0, 10, 100, 1000, 10000, etc all of which add to 1. In light of the fact that the Vedas, literally ā€œthe illimitable storehouse of All Knowledgeā€ came under 4 headings or categories like the Rig Veda, the Yajur Veda, the Sama Veda, and the Atharva Veda. Thus a Vedic Mathematician was also an astronomer, healer, and poet. It was a total system if you are out in the field and you need to tile a square floor that is, say 108 units square. How do you do it with mental ease? I think only of the excess ā€œ8ā€, saying how much is 108 more than my Base of 100. It is ā€œ8ā€. So we will merely add this ā€œ8ā€ to the number in question ā€œ108ā€ and tag on the squaring of this excess: 108 Squared = 108 + 8 / 8Ɨ8 = 116 / 64 = 11,664.Vedic mathematical methods are derived from ancient systems of computations, Compared to conventional mathematical methods, these are computationally faster and easier to perform. An application of Vedic mathematics can be effectively increased if it can make available to the beginners in various fields of study

    STUDY OF CHARKOKTA ANGULA PRAMANA OF SHADANGA AND ITā€™S IMPACT ON PHYSICAL HEALTH

    Get PDF
    Body parts and their Pramana are specially described in Ayurveda which is an important part of Rachana Sharir. Description of Angula Pramana was found in Vedic Kala, Purana-Upanishad Kala. Samhita Kala like Vrahtai (Charaka Samhita, Sushruta Samhita, Ashtanga Sangraha, Astanga Hridya) Kashyapa Samhita, Bhela Samhita, Sharangadhara Samhita, Vangsena Samhita, and Kautilya Arthashastra. Pramanas are not useful only in Rog and Rogi Pariksha but also useful to know about his/her Ayu such as Hitaayu, Ahitaayu, Sukhayu and Dukhaayu. At the time of Acharya Charaka, the length and breadth of different Anga-Pratyanga was measured by using their own fingers. This technique of measurement is known as Anguli Pramana. Anguli Pramana which is based on Swa-Angula Pramana is used for measuring the dimensions (Ayam, Vistara and Parinaha etc.) of the different Anga Pratyanga of the body. The study was conducted on 200 volunteers in the age group of 16-40 years. One Angula as a unit of Angula Pramana was obtained by measuring the width of Madhyamparva of middle finger of working hand. The measurements were taken in centimetres for standardization as per metric system and then converted into Anguli Pramana based on individual. This article summarizes the facts related to Anguli Pramana from classical literature, Ayurvedic literature and modern literature along with result of our research work to identify the anatomical landmark of Shadanga to measure through Anguli Pramana and its impact on physical health in present era. At present, there are many physical anomalies either they are genetic disorders, endocrine disorders, traumatic injury which results as anatomical disfiguration of body parts that can distinguish from their Anguli pramana or anthropometry

    Aim- To correlate association of ultrasonographic markers in antenatal patients with subsequent development of preeclampsia Material Method - 131 pregnant women, in first trimester of pregnancy were investigated for their uterine artery Doppler and  placental volume. These patients were followed up till term for the development of preeclampsia. Results: Out of 131 antenatal cases 20.61% developed preeclampsia. Uterine artery Pulsatility index >95th percentile(>2.3) with mean 2.08Ā±0.43(p value 0.0001) predicted pre eclampsia with sensitivity of 51.85% with specificity of 95.19%. Similarly Resistance index of Uterine artery >95th  percentile(>0.8) with mean 0.771Ā±0.084(p value 0.018) predicted pre eclampsia with sensitivity of 48.15% and specificity of 87.50% . Placental Quotient <10th percentile (<0.81) with mean 0.89 (p value 0.0001)predicted pre eclampsia with sensitivity of 40.74% and specificity of 96%.On combining all three ultrasonographic parameters the sensitivity for prediction of preeclampsia was increased to 70.37% with specificity of 86.54%  with PPV of 36.74% % and NPV of 96.34% %. Conclusion: Maternal ultrasonographic markers like Uterine artery PI, RI, Placental Quotient levels vary between normal pregnancies and those that subsequently developed preeclampsia. Thus our study concludes that  first trimester screening with ultrasonographic markershave high sensitivity, specificity and negative predictive value in detection of preeclampsia

    Lightweight and solution processible thin sheets of poly(o-toluidine)-carbon fiber-novolac composite for EMI shielding

    Get PDF
    An attempt has been made to generate lightweight and processible thin sheets of poly (o-toluidine)-carbon fiber (PoTCF) composite for electromagnetic interference shielding. PoTCF composite synthesized by oxidative emulsion polymerization was physically blended with different weight ratios of novolac resin to prepare a new class of composite material, which was further processed to form thin sheets (thickness of similar to 0.85 mm) by a compression moulding technique. In situ incorporation of carbon fiber into the polymer matrix leads to the formation of composites with improved mechanical, thermal, electrical and shielding properties, which were further optimized by varying the amount of novolac resin in the sheets. Structural and morphological studies were carried out by UV-vis, FTIR, XRD and SEM. PoTCF composite sheets with 50 wt% loading of novolac resin have flexural strength of 36.0 MPa and exhibit a shielding effectiveness of 24 dB in the X-band (8.2-12.4 GHz) at a critical thickness of similar to 2.11 mm, which is more than the limit required for techno-commercial applications. Therefore, indigenously fabricated polymer-based sheets would be potentially useful for making durable enclosures for electronic equipment

    The experience of smart farming can be improved using IoT-based applications. Still, the performance of IoT networks may be degraded due to different factors, i.e., the coverage area of the farm/location (surface or underwater)/environmental conditions etc. Network operations over heterogeneous environments may cause excessive resource consumption and thus may reduce the IoT sensorā€™s lifespan. To optimise energy consumption, in this paper, an energy-efficient method will be introduced for smart farming, and its performance will be analysed using different parameters (i.e., Throughput/energy consumption/residual energy etc.) using two different IoT standards (Long Range Low powered technology (LoRa)/SigFox)
