Priyanka Rajan Kumar, Sonia Goel — Sat, 30 Dec 2023 00:00:00 +0000

E-Health is a system of providing health services by making use of electronic technologies. They provide improved, flexible, and affordable health services to a large population, especially in situations like a pandemic. The IoT is helping them to connect, generate and share a huge amount of data. This system of online sharing of health records and advice is generating data at rapid growth. This large data is to be managed in terms of storage, processing, transmission, privacy, and security. The cloud came up as a source of big data management but when it came to latency and bandwidth consumption, a system of processing near the edge came as a Fog Computing with distributed processing, reduced delay, and less bandwidth. The Fog is near the generation of data that provides benefits like location awareness, heterogeneity, real-time access, wireless access, and scalability. Here the security of sensitive data is a prime factor. Security can be achieved with cryptography. The paper implemented RSA, BLOWFISH, AES, and Integrated Encryption Scheme of (RSA+BLOWFISH) and (RSA+AES) combination security algorithms in the Fog-enabled E-Healthcare system. The comparison of performance is done on the basis of key size, encryption-decryption time, and throughput. It is found that BLOWFISH has the least encryption-decryption time and more throughput in a single encryption scheme. In the Integrated Encryption Scheme, the (RSA+AES) combination has improved performance among the two combinations. So, to achieve the security of the E-Health system in the Fog computing environment it is more efficient to use Integrated Encryption Scheme.

Dr. Amrit Kaur, Dr. Sonia — Wed, 28 Feb 2024 00:00:00 +0000

The Corona Virus Disease (COVID-19) pandemic has upended the lives of people all over the world, and people have realized that the demand for new technologies, such as Internet of Things (IoT)-based devices, Vehicle Adhoc Networks (VANETS), and other upcoming technologies is increasing nowadays. These technologies are mostly based on controlling objects from a remote location, and some of them avoid close contact with others. So, a 5G network with more bandwidth is beneficial but the higher frequency signals will have more collisions with obstacles in the air, and thus it tends to reduce its energy more quickly. As a result, 5G networks are segregated into small cells to alleviate this issue but at the same time it is difficult to manage the handover process in small cells. To optimize the handover process, an Adaptive Neuro-Fuzzy Inference System (ANFIS) is adopted in this research. The structure, as well as the input and output variables have been developed, and the rule base mathematical model, which describes all the possible handover scenarios based on these parameters, has been evaluated. A MATLAB simulation was used to test the effectiveness of the proposed handover ANFIS.

Therefore, in this research article, a 160 Gbps-100 GHz RoF system is presented over 160 km link distance by employing PDM-256-QAM and matched filter. Moreover, the eradication of dispersion, time skews, phase compensation and nonlinear effects have been performed by employing different algorithms such as blind phase search (BPS), constant modulus Algorithm (CMA), and viterbi phase estimation (VPE).The presented system is investigated for discerning the effects of different RF frequencies, input powers, matched filter bandwidths on polarization X and y in terms of log bit error rate (log BER), symbol error rate (SER), Q factor, and error vector magnitude (EVM). Results revealed that polarization exhibited better performance as compared to polarization X.

Due to the expansion of world of the internet and the quick acceptance of platforms for social media, information is now able to exchange in ways never previously imagined in history of mankind. A social networking site like Twitter offers a forum where people may interact, discuss, as well as respond to specific issues via short entries, like tweets of 140 characters and fewer. Users may engage by utilizing the comment, like and share tabs on texts, videos, images and other content.Although platforms for social media are now so extensively utilized, individuals are creating as well as sharing so much information than shared before, which can be incorrect or unconnected to reality. It is difficult to identify erroneous or inaccurate statements in textual content autonomously and find emotions of people. In this paper, we suggest an Ensemble method for sentiment and emotion analysis. Different textual features of actual and Emotion and sentiment have been utilized. We used a publicly accessible dataset of twitter sentiment analysis that included total 48,247 authenticated tweets out of 23,947 of which were authentic positive texts labelled as binary 0s and 24,300 of which were negative texts labelled as binary 1s. In order to assess our approach, we used well-known (ML) machine learning models such as Logistic Regression (LR), Decision Tree (DT), AdaBoost, SGD, XG-Boost, and Naive Bayes. In order to get more accurate findings, we created a multi-model sentiment and emotion analysing system utilizing the ensemble approach and the classifiers stated above. Our recommended ensemble learner method outperforms individual learners, according to an experimental study.

Vipul Devendra Punjabi, Dr. Rajesh Kumar Shukla, Dr. B. V. Kiranmayee — Wed, 28 Feb 2024 00:00:00 +0000

A significant source of local and international news for millions of individuals, online social networking websites are rapidly growing. OSNs, on the contrary side, have two disadvantages. Despite the numerous benefits they provide, such as endless, simple communication and instant access to data and news, they can also come with a number of drawbacks and concerns. The spread of misleading information is one of their toughest obstacles. Fake news detection is a difficult & unsolved issue. Nevertheless, designing a solution is anything but straightforward given the unique characteristics and challenges of identifying bogus news on OSNs. Artificial intelligence (AI) techniques, on the other hand, are still incapable of overcoming this difficult obstacle. Even worse, by creating and disseminating false information, artificial intelligence (AI) systems like deep learning and machine learning are being abused to trick customers. Because the material is meant to closely mirror reality, it can occasionally be difficult to assess its reliability using AI alone and without support from outside sources. As a result, it's still very difficult to recognise bogus news automatically. This research seeks to offer a fundamental review of the methods currently used to recognise false news and prevent it from spreading over OSNs in addition to classifying fake news using several classifiers.

We review the use of Mode Division Multiplexing (MDM) as a multiplexing technology for the realization of passive optical networks. We start with approaches for MDM realization – with the use of complex MIMO digital signal processing or without complex DSP using few mode fibers. We proceed to explain basic architecture of MDM PON, and its hybrid with time division multiplexing - TDM MDM PON and hybrid of time, wavelength and mode division multiplexing – MDM TDM WDM PON. We then proceed to discuss recent progress in the field of Mode Division Multiplexing.

Arsh Mahajan, Kulwinder Singh Malhi — Sat, 30 Dec 2023 00:00:00 +0000

In this paper, a design of 40 Gb/s free space optics (FSO) transmission link is proposed employing orbital angular momentum (OAM) multiplexing technique under the different weather turbulence such as clear sky, rain, fog, haze and dust. The system has four channels comprised of OAM multiplexed laser beams such as LG0,0, LG0,13, LG0,40, LG0,80, for realization free space transmission. It has been observed that Interchannel interference is a performance deteriorating constraint is in multi-channel OAM multiplexed FSO systems. To suppress of inter-channel interference a transmitter diversity NRZ/RZ formatting technique has been incorporated. A graphically representation of performance comparison is established considering return-to-zero (RZ), alternate mark inversion (AMI), non-return-to zero (NRZ) and transmitter Diversity- (TD)-NRZ/RZ modulation signal encodings in terms of bit error rate (log BER). The Results revealed that the system performance is better with TD-NRZ/RZ encoding compared to other techniques and it covers a transmission range from 67 to 1200 m depending upon the weather conditions.

Shivmanmeet Singh, Narwant Singh Grewal, Baljeet Kaur — Sat, 30 Dec 2023 00:00:00 +0000

Information transmission channels are essential for global coverage in space communication. Since radio frequency (RF) communication has been shown to have a significant latency and low data transmission rates, inter-satellite communication has grown in popularity recently and optical wireless communication has made significant strides. Inter Satellite Optical wireless Communication (IsOWC) technology is gaining popularity among academics due to its many benefits, including huge channel bandwidth, high-speed connection, and cost-effective operations. High speed inter-satellite communication cannot be conducted using uniphase modulations like NRZ modulation. With the aid of a matching filter and DSP, PDM 512 QAM at 160 Gbps is shown for conducted study. At wavelengths of 850 nm, the proposed work is explored for PDM 512 QAM, and the results are assessed with consideration of the quality factor, symbol error rate, and error vector magnitude.

RECOMMENDING CLONES FOR REFACTORING USING COMMIT MESSAGES

Manpreet Kaur, Dhavleesh Rattan, Madan Lal — Sat, 30 Dec 2023 00:00:00 +0000

Software can have many clones which are required to be managed. One possible method of clone management is refactoring. But all clones do not require the attention of developers for their management through refactoring. There is a need to develop tools that understand the developers' real intent behind clone management and recommend suitable clones for refactoring. In this paper, we proposed an approach that uses commit message analysis for recommending suitable clones for refactoring.
