Abstract: As the country’s housing stock grows, so does the number of burglaries and other crimes. Burglary is an unwelcome occurrence that no one wants to occur on their property. It is, however, difficult for everyone to remain vigilant at all times in order to defend their property or identify an unofficial entry. As a result, an IoT-based  burglar/intruder detection and alert system is required to prevent interruption to every home and resident, particularly as crime rates rise. This paper demonstrates the use of low-cost, low-power consumption wireless security technologies to construct a security system for homes or businesses. These systems can be used to protect banks, offices, and other places. This paper is about an eco-friendly burglar/intruder detection and alert system based on the ESP8266 microcontroller. This ESP8266 module will lower the system’s cost and power usage. When there is presence of intruder, the owner will receive a notification via an Android Application. As a result, the user gets alerted.

Abstract: Mobile phones are a very integral part of our day to day life. But with tech advancing at the rate at which it is, devices tend to go outdated within one or two years since their launch due to a lack of updates, patches and support from the manufacturer, even though they are capable of running for longer than that. This project aims to tackle that issue and increase the lifespan and usability of a device, performance, provide the latest security patches and update it to the latest stable android version. Using Google’s Android Open Source Project, we build our own version of the Android Operating System, which will be able to run on older hardware, provide more customizations, etc.

We build a custom android based OS using a Linux based computer with all necessary installations, the AOSP source, device trees and the Android Make Build System (Make/Soong).

Abstract: Battery life remains one of the most critical factors influencing user satisfaction in mobile devices. With the increasing complexity of mobile applications, continuous background processes, and hardware-intensive features such as AI inference, location tracking, and real-time analytics, power consumption has become a major design challenge. Apple’s iOS platform has continuously evolved its battery optimization strategies by combining system-level controls with artificial intelligence driven power management techniques. Recent versions of iOS integrate machine learning models to predict user behavior, optimize background activity, and dynamically manage CPU, GPU, and network resources. This paper presents a comprehensive review of battery optimization techniques in iOS, with a special focus on AI-driven power management mechanisms. It discusses traditional energy-saving approaches, system architecture, developer-level APIs, and the role of on-device intelligence in adaptive energy control. Furthermore, this paper compares conventional rule-based power optimization with AI-assisted strategies and analyzes their impact on application performance and user experience. Challenges, limitations, and future research directions are also highlighted. The study aims to provide useful insights for iOS developers and researchers working on energy-efficient mobile computing.

Abstract: In the ever-evolving world of mobile applications, quality assurance (QA) plays a significant role in delivering reliable, user-friendly experiences. Mobile QA typically involves two main testing approaches: manual testing and automated testing. Each has its own strengths and limitations. Manual testing allows human testers to explore user experience scenarios intuitively, while automated testing offers speed, repeatability, and coverage of large test suites. This paper reviews the synergy between manual and automated testing in mobile QA, discussing how a balanced approach can lead to more robust quality outcomes. We look at the unique challenges in mobile environments, propose models for integrating manual and automated processes, and include real-world case summaries. The study also includes tables summarizing factors for selecting between manual and automated testing, tools comparison, and process integration steps. The objective is to highlight that neither manual nor automated testing alone is sufficient for comprehensive mobile QA; instead, their hybrid approach yields better efficiency, accuracy, and user satisfaction.

Abstract: Accessibility in mobile applications has become a critical aspect of modern software development, driven by increasing awareness, legal mandates, and the need for inclusive digital experiences. Apple’s iOS platform provides a comprehensive set of accessibility tools and frameworks that enable developers to build applications usable by individuals with visual, auditory, motor, and cognitive impairments. Despite strong platform-level support, practical implementation of accessibility in iOS apps continues to face numerous technical, design, and organizational challenges. This paper presents a detailed review of accessibility implementation in iOS applications, focusing on key technologies such as VoiceOver, Dynamic Type, Switch Control, and AssistiveTouch. It also examines common challenges developers encounter, including insufficient testing, design trade-offs, lack of awareness, and performance constraints. Through analysis of existing literature, Apple documentation, and real-world development practices, this paper highlights current gaps and proposes best practices for improving accessibility adoption. The study concludes that while iOS offers robust accessibility infrastructure, achieving truly inclusive apps requires early design integration, continuous testing, and stronger collaboration between designers and developers.

Abstract: The iOS development ecosystem has evolved significantly over the past decade, with Apple providing multiple frameworks for building user interfaces. UIKit, introduced in 2008, has been the foundation of iOS app development for over a decade, providing mature and robust tools for interface creation. In 2019, Apple introduced SwiftUI, a declarative framework designed to simplify UI development while promoting code reusability and modern development practices. This paper provides a comparative review of SwiftUI and UIKit, focusing on performance metrics, developer productivity, learning curve, scalability, and ecosystem compatibility. Benchmarks and case studies are used to evaluate rendering efficiency, memory usage, and speed of UI updates. Additionally, developer surveys and productivity analyses provide insights into how each framework impacts coding efficiency and project timelines. Results indicate that SwiftUI offers faster development cycles and more concise code but may face limitations in complex or legacy project integration, whereas UIKit continues to offer unmatched performance control and backward compatibility. Recommendations are provided for framework selection based on project scope, team expertise, and performance requirements.

Abstract: Jetpack Compose, introduced by Google in 2019, represents a modern approach to building native Android user interfaces (UI) declaratively, replacing traditional XML-based layouts. This paper reviews the adoption trends of Jetpack Compose, its performance impact, and the comparative advantages and challenges developers face during migration from legacy UI frameworks. We analyze both industry adoption and open-source project trends, followed by empirical performance tests measuring rendering times, memory consumption, and responsiveness in common UI patterns. Our findings indicate that Jetpack Compose improves developer productivity, reduces boilerplate code, and offers comparable or slightly better runtime performance in modern Android devices. We also discuss limitations such as learning curve and interoperability with legacy code. The study provides actionable insights for organizations considering full-scale Compose adoption and establishes a framework for future performance evaluation.
