 Abstract

Scene boundary detection is crucial in applications like scene segmentation and video skimming, but the presence of ad clips makes it difficult. There are some existing methods based on visual, audio-visual and audio-only features. The existing audio-only feature-based method depends on short silences between program and ad or between ads. Still, short silences can also be present inside the program, affecting performance. So we proposed a detection method for ad shots using MFCC features. MFCC is a basic speech feature based on short-term spectral. We used the average of MFCC for a shot and determined the threshold for detection purposes. We used four episodes of The Big Bang Theory as our dataset. Our method is the first method that uses MFCC features for ad detection and explores the relation between video contents and MFCC features.

 Abstract

Immersive technology is a fast-growing, fascinating, and groundbreaking domain that interests the majority of people. Concisely, immersive technologies widen reality to a greater extent. VR transports the user into a totally different virtual simulator environment. This innovative and fascinating technology is growing at a very fast pace giving hopes for a more digitalized future.Virtual Reality creates a simulator environment, by wearing a headset, so the user can experience an entirely different reality. Augmented Reality is the laying of digital elements into the real physical world. Mixed Reality merges real and virtual environments to produce new visualizations and experiences in real-time. Our major concern is Augmented Reality AR.

 Abstract

Pb1-xZnxS (x=0 to 0.4 in steps of 0.1) ternary semiconductor compounds were synthesized by co-precipitation technique. XRD studies revealed that the compounds are polycrystalline in nature with cubic structure. Variation in density and porosity percentage, dislocation density, lattice strain and average grain size of all samples, with respect to change in Zinc concentration, were calculated.

 Abstract

Tomatoes contain a lot of water, making them more prone to deterioration due to the action of numerous microbes. This makes storage and shipping difficult for this vegetable. Tomatoes are a common vegetable that is eaten fresh in salads, garnished on other foods, and cooked to provide flavours to a variety of dishes. As a result, it is a common food component in both Asian and European countries. Furthermore, tomatoes are high in vitamins, particularly vitamin A, as it contains the precursor -carotene, which is critical for vision. It is also a good supplier of minerals, making it an important food component. Bacteria, the fungus was shown to be the source of spoiling in the majority of the samples. This review paper aims to study various microorganism which are involved in spoilage of tomatoes. This can help in creative different majors for preventing spoilage of tomato. Also, these fungi are the source of highly potent mycotoxins, which can cause serious food poisoning and even death review, the results can be dangerous. We have made an effort to list all of the tomato-related causes that have been researched in this review.

 Abstract

An app, which is short for "application," is a type of software that can be installed and run on a computer, tablet, smartphone or other electronic devices. A mobile application is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Mobile apps allow users to have easy, smooth, functional access to information, products, services and processes that they need in real-time and are optimized for hands on interaction. The messaging apps are used for interacting purposes with others. Chat based applications will provide a way for easy communication through chatting, voice calls, etc. DMgram is a messaging application designed to provide users with features such as one-to- one chat, group chat, camera, scheduling of messages, hiding "online" status and mainly with a alert system. Alert system is being designed where the primary purpose is to alert the guardians or parents when their child uses certain words such as drugs, elope, etc. One-to- one chat is enabled to increase the interaction between two users and also make sure that a single person is connected and is interactive with a group of people through group-chat feature. Other features such as camera option is provided in order to send photos and videos to their contacts on DMgram, scheduling of messages is enabled using which a message can be scheduled and is delivered to the specified contact and hiding the "online" status where the person can enable the and disable the visibility of their online status whenever wanted.

 Abstract

Deep learning (DL) has proven beneficial in medical imaging, and several research have begun to study DL-based solutions for the aided detection of lung disorders in the aftermath of the recent COVID19 epidemic. While previous research has focused on Chest Computed Tomography (CT) scans, this study investigates the use of Deep learning approaches to analyse lung ultrasonography (LUS) data. Which provide a new completely annotated dataset of lung ultrasonography images are gathered from multiple hospitals and some web resources, with reflecting labels shows the severity of illness at the frame and pixel levels. At frame levels, deep networks having Spatial Transformational Network (STN) are introduced to analyse the severity of disease automatically in lung ultrasonography images. In this proposed system, a deep network named Convolutional Neural Networks (CNN) based transfer learning is used and developed from Spatial Transformer Networks (STN) that which predicts the disease from the given image. Once after the disease prediction, U-Net Will applied for the segmentation of the predicted disease part from the given image.

 Abstract

With the increase in the number of complex high rise buildings, ensuring safety is a primary requisite. In the event of an emergency such as an earthquake or a fire, the protocol followed is exiting the building as soon as possible. But in such modern day complex buildings, evacuation becomes slightly more complicated as they have multiple levels, limited exits and house larger number of people. This calls for a system that evacuates people efficiently. The Emergency Evacuation System (EES) based on Internet of Things (IoTs) aims to achieve an effective evacuation process that ensures safety and minimum casualties using sensors for early detection and monitoring, an alarm for warning about the casualty and application for evacuee guidance and easy navigation. In the occurrence of an emergency, the EES detects it, alerts the civilians in the building and provides guidance through an application.
