Surveillance scene classification using machine learningUtkarsh Contractor
The problem of scene classification in surveillance footage is of great importance for ensuring security in public areas. With challenges such as low quality feeds, occlusion, viewpoint variations, background clutter etc. The task is both challenging and error-prone. Therefore it is important to keep the false positives low to maintain a high accuracy of detection. In this paper, we adapt high performing CNN architectures to identify abandoned luggage in a surveillance feed. We explore several CNN based approaches, from Transfer Learning on the Imagenet dataset to object classification using Faster R-CNNs on the COCO dataset. Using network visualization techniques, we gain insight into what the neural network sees and the basis of classification decision. The experiments have been conducted on real world datasets, and highlights the complexity in such classifications. Obtained results indicate that a combination of proposed techniques outperforms the individual approaches.

Real-Time Pedestrian Detection Using Apache Storm in a Distributed Environment csandit
In general, a distributed processing is not suitable for dealing with image data stream due to the
network load problem caused by communications of frames. For this reason, image data stream
processing has operated in just one node commonly. However, we need to process image data
stream in a distributed environment in a big data era due to increase in quantity and quality of
multimedia data. In this paper, we shall present a real-time pedestrian detection methodology in
a distributed environment which processes image data stream in real-time on Apache Storm
framework. It achieves sharp speed up by distributing frames onto several nodes called bolts,
each of which processes different regions of image frames. Moreover, it can reduce the
overhead caused by synchronization by computation bolts which returns only the processing
results to the merging bolts.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
2. Outline
• What is the three-dimensional particle tracking velocimetry
• What is the main contribution to turbulence research
• What are the limitations and possible solutions
• The (only) working solution example - Ron Shnapp
3. The take-home message
• You can do it and you better do it
• Real-time image analysis on a dedicated hardware is a key for
long-recording, high-speed 3D-PTV
• Paradigms about 3D-PTV changes from in-lab table-top
experiments to wind tunnel and field experiments
• You can readily get data sets of millions of tracer trajectories
like the one recorded in a canopy flow model in an
environmental wind tunnel, providing Lagrangian velocity and
acceleration distributions in an urban canopy flow model
