An Effective Solution Towards Solving the Problem of Deepfake

2023-05-22T10:49:51+00:00

The use of advanced AI algorithms is growing daily, resulting in increasingly realistic fake videos with facial superimposition that are being produced by AI, as these videos involve well-known people, their behavior can have severe consequences. The videos have the potential to not only spread false information that harms the status of individuals, businesses, and nations, but also to trigger widespread hysteria and civil unrest. Therefore, to stop the rapid spread of Deepfake it is of extreme importance to identify it first. A novel Residual Network based model that learns inherently distinct patterns that change between a real video and a Deepfake is proposed in this paper as a method for detecting Deepfakes. An Inception Residual Network Version 2 has been trained by the proposed model to successfully differentiate Deepfake videos using different features of a frame-based approach. This work shows that our model can be used to accurately identify Deepfake faces in each video source. This will help security applications effectively reduce the ever-increasing threat of Deepfakes.

Tetrahedral Hyper-Cube: A New Scalable Hybrid Interconnection Network for Massive Parallel Processing

2023-05-22T10:57:36+00:00

This paper introduces an enhanced highly scalable, recursive and hierarchical interconnection topology called the Tetrahedral Hyper Cube (THC) for high end computing systems. As compared to the other interconnection networks THC is found to be more attractive in terms of various topological attributes such as node connectivity, edges, average node distance and message traffic density etc. The proposed network is bipartite and highly scalable and also robust in nature than the other popular network topologies like Hyper cube (HC), Folded Hypercube (FHC), Exchanged hyper cube (EC), Mobius cube (MC) and Torcube (TC). With increased node count, the average node distance and message traffic density for THC is relatively small. The main attractive property of THC is its comparatively low link complexity which makes it a superior choice for massive scale computing. The optimal peer to peer minimal routing and broadcasting algorithms for the new network are also presented. The isoefficiency of THC lies between 0.6 to 0.56 for a varied magnitude of dimension. The packing density is four times that of the n dimensional hypercube. The detail analysis reveals that the THC topology is an efficient enhancement of the popular Hypercube topology and its variants.

RTO Management System Using Blockchain

2023-05-22T12:32:47+00:00

As the world's population continues to grow, so too does the number of vehicles on the road. It is imperative that drivers possess the proper license and vehicle papers as required by law. However, it can be inconvenient for drivers to carry physical copies of these documents at all times, and the process of verifying them can be time-consuming for traffic police who also need to maintain accurate records of issued challans. To streamline this process, we propose the implementation of a system whereby drivers can register with the RTO services and receive unique login credentials. Through this system, drivers can upload all necessary documents, including their RTO driving license, thereby eliminating the need for hard copies. In addition, drivers can utilize the system to file complaints against any police misconduct.

When traffic police need to verify a vehicle's documents, they can simply enter the vehicle number into the application. The system will then fetch relevant data from the server and display all pertinent information, including emission and insurance details. Moreover, traffic police can use the system to generate challans, which will be linked to the specific vehicle and subsequently paid online by the driver. This approach benefits both drivers and traffic police alike, as it simplifies and automates what can be an arduous process while simultaneously ensuring compliance with all necessary regulations.

Use of Mobile App - Detect SOC to digitize and analyse the readings acquiredthrough SOCDK while checking the level of Soil Organic Carbon in agriculture soil from sample farms

2023-05-25T10:48:57+00:00

The level of atmospheric carbon has increased since the advent of industrial revolution in 18th century. Several innovations and inventions lead to a progressive lifestyle and the consequent burning of fossil fuels. Over a period of time these activities of combustion led to the increase of atmospheric CO2 and eventually global warming. This further disturbed the natural course of seasons across the globe. Today we nearly stand at the threshold of extinction of the globe if the emission of greenhouse gasses is not controlled. Agriculture is one of the prime sectors and is responsible for the contribution of greenhouse gasses, of which CO2 is prominent. As a matter of fact, the Agriculture sector behaves as a source and sink of CO2. Availability of organic carbon in the soil is an indicator that the soil is rich in micronutrients which are essential for a voluminous and good quality crop. Till date several tools of Information Technology have been applied to evaluate the level of SOC in soil. This applied research study probes into the use of Information Technology in the form of a Mobile App - Detect SOC for evaluating the Soil Organic Carbon (SOC). The readings of the Detect SOC App are calibrated against the results of SOCDK kit for the said agriculture soil samples. Based on the evaluated level of SOC the Mobile App provides suggestions to enhance the level of SOC in the sample soil.

2023-05-25T11:12:41+00:00

Machine learning can be used to optimize the application of pesticides in agriculture by predicting the amount of pesticide needed based on various factors such as crop type, growth stage, weather conditions, and soil composition. This can help reduce the amount of pesticide used, increase crop yield, and minimize environmental impact.Machine learning algorithms like logistic regression classification, polynomial regression, and K-nearest neighbor (KNN) can be used to classify which sections of a crop field require repeated pesticide spraying.These algorithms can analyze data on factors such as weather conditions, soil type, pest populations, and previous pesticide applications to determine which areas of the field are most susceptible to pest damage. By using this information, farmers can target their pesticide applications to only the areas that need it, instead of spraying the entire field repeatedly. Thus, in the paper, we discussed accuracy percentages based on different machine learning algorithms.

2023-06-02T11:25:41+00:00

Skin cancer is a widely spread type of cancer that impacts a significant number of individuals globally. As per the data presented by the World Health Organization, almost 2-3 million cases of non-melanoma skin cancers and about 132,000 cases of melanoma skin cancers are identified every year. The survival rate decreases as the skin cancer stage progresses. The timely identification of skin cancer can significantly improve the survival rate of patients by up to 74%. However, it is an expensive and challenging procedure to identify the cancer type in the early stages. Machine learning and deep learning have the potential to make a significant impact on the classification of skin cancer. A robust medical support system for classifying skin cancer from dermoscopic images is required for the prognosis of skin cancer. Therefore the primary objective of our research is to develop a model which automatically classifies skin cancer into distinct types. We conducted several experiments on skin cancer dataset utilizing machine learning and deep learning techniques, including fine-tuning and transfer learning. We observed that the deep learning fine-tuned model, which utilized the Densenet201 architecture to implement fine-tuning, performed exceptionally well across all experiments. Furthermore, we evaluated the performance of all models to classify seven types and further three categories of skin cancer. The accuracy levels achieved by all classification models were notably commendable, meeting the established benchmark for classification.

Risk - Return Analysis of Selected Mutual Fund Companies listed in NSE

2023-06-05T07:35:48+00:00

Since the liberalization process began in 1992, Mutual Funds, which are a component of the Indian Financial Sector, have risen significantly in the economic hierarchy. The capital market reforms and economic expansion that permitted the mutual fund industry's fast rise also provide a clear path for this sector's future development. Only a small portion of savings are now making their way to the stock markets via mutual funds. They are relatively simple, cost-effective, and don't require an investor to choose which securities to buy. Because only 2 to 3 percent of all Indians invest in mutual funds for a variety of reasons, familiarity with the companies that offer these plans is now required. This study will help identify the risk and return of the mutual fund companies that are listed on the National Stock Exchange (NSE).

Parallel mediation analysis of self-image and perceived usefulness between job security, habit, organizational culture and intentionto use AI technologies

2023-06-05T07:41:18+00:00

With technology advancing at a much faster rate today, organisations risk obsoletion if they do not keep up with the fast pace and adoption of artificial intelligence (AI) technologies. The most important aspect of adopting AI technologies is how employees will respond to it. Employees make the core of an organization, and if they do not respond well to changes, the company will be adversely affected. This research report aims at examining whether job insecurity, habit, organizational culture, perceived self-image, and perceived usefulness affects employees’ intention to use AI in the workplace. Data was collected from 204 Indian ITES employees. Three mediation models were hypothesized and explored. For all the three models, parallel mediation analysis was conducted using Hayes’ PROCESS Macro (Model 4). The results from the first model indicate that job insecurity directly affects the intention to use artificial intelligence technology among the respondents. In the second model, both self-image in using technology and perceived usefulness emerged out to be mediators between habit of the respondents and their intention to use AI. From the third model, the results indicate that self-image in using technology and perceived usefulness mediates the relationship between perceived organizational culture and intention to use AI. The study will help the ITES business organizations prepare their employees for radical shifts in technological adoptions to prevent their discomfort. The first step in this process would be to identify the variables affecting their employees’ intention to use artificial intelligence and this research report helps in studying such variables.
