Local differential privacy (LDP) has been established as a strong privacy standard for collecting sensitive information from users. Although it has attracted much research attention in recent years, the majority of existing works focus on applying LDP to frequency distribution estimation for each individual value in a discrete domain. This paper concerns the important range queries involving multiple discrete values. Till now, only a few works target this problem. They all rely on the B-ary tree to construct a uniform and hierarchical decomposition, so as to decrease the error when answering large range queries. However, the uniform splitting manner ignores the properties of decomposed sub-domains and processes them equally without preferences, which leads to significant performance *** this paper, we tackle the problem head on: our proposal, privNUD, is a novel domain hierarchical decomposition mechanism. It dynamically decomposes each domain with a tailored granularity into some sub-domains, which sensitively considers the potential chances to answer one range query. The issue of granularity is carefully analyzed for better performance. It also can smartly prune the sub-domains with small frequencies. Besides, an adaptive user allocation technique is designed to dynamically decide the scale of users that are involved in each sub-domain's frequency estimation. Extensive experiments using real and synthetic datasets demonstrate that privNUD achieves significantly higher result accuracy compared to the up-to-date solutions. © 2023 IEEE.

Recent neural models for video captioning usually employed an encoder-decoder framework. However, most approaches either neglected the spatial and temporal interactions between objects in a video or implicitly modelled the interactions, resulting in less desired performance. In this paper, we propose a novel relation-aware graph learning framework. It explicitly models both spatial and temporal relations for objects. In particular, a relation-aware graph is designed to depict the spatial relations between different objects in a scene. Parallelly, a temporal graph network is designed to perform relational reasoning for the same objects in adjacent frames. Features of both types of relations are learned and fused for the follow-up language decoder. Experiments on two bench-mark datasets show the effectiveness of our framework. It achieves state-of-the-art performance with CIDEr scores on MSVD and MSR-VTT. © 2023 IEEE.

Many recent studies have been reported that the current distribution has non-uniformity in IGBT under Unclamped inductive switching (UIS) condition. Those discussions are based on the calculation result performed using device simulators. And, the observation of thermal action of device has been reported by using the IR thermography. The non-uniform temperature distribution on chip and thermal map change at every several micro second periods. In this study, time resolved emission (TRE) microscopy was used to get highly precise data. The probability distribution of current in the IGBT under UIS condition was observed. Also, a change of current distribution dependent on the time and motion of current concentration were detected. These areas of high current density existence probability move along termination region of device 1.75μs after avalanche breakdown with damping. This is the first study to show the direct motion observation of photon emission from the current fllamentation in IGBT under avalanche breakdown condition. © 2016 IEEE.

This study investigates public attitudes towards the COVID-19 vaccine through Twitter data analysis. Using the Twitter API, tweets were collected, preprocessed, and labeled. Features were extracted using the Bag of Words representation, and sentiment analysis was conducted using Text Blob and Vader. Machine learning and deep learning models were trained and tested, revealing that deep learning models achieved the highest accuracy and F1 score. The research underscores the efficacy of machine learning and deep learning in analyzing COVID-19 vaccine-related tweets, shedding light on factors influencing vaccine resistance. These insights are crucial for pharmaceutical companies and public health officials, enabling them to address barriers to vaccine acceptance and enhance the societal benefits of widespread vaccination, contributing to the pandemic's resolution. © 2023 IEEE.

Requirements changes sometimes cause a project to fail. A lot of projects now follow incremental development processes so that new requirements and requirements changes can be incorporated as soon as possible. These processes are called integrated requirements processes, which function to integrate requirements processes with other developmental processes. We have quantitatively and qualitatively investigated the requirements processes of a specific project from beginning to end. Our focus is to clarify the types of necessary requirements based on the components contained within a certain portion of the software architecture. Further, each type reveals its typical requirements processes through its own rationale. This case study is a system to manage the orders and services of a restaurant. In this paper, we introduce the case and categorize its requirements processes based on the components of the system and the qualitative characteristics of ISO-9126. We could identify seven categories of the typical requirements process to be managed and/or controlled. Each category reveals its typical requirements processes and their characteristics. The case study is our first step of practical integrated requirements engineering. Copyright © 2010 The Institute of Electronics, information and Communication Engineers.

Cloud computing will be a main informa- tion infrastructure in the future; it consists of many large datacenters which are usually geographically distributed and heterogeneous. How to design a secure data access for cloud computing platform is a big challenge. In this paper, we propose a secure data access scheme based on identity-based encryption and biometric authentication for cloud computing. Firstly, we describe the security concern of cloud computing and then propose an integrated data access scheme for cloud computing, the procedure of the proposed scheme include parameter setup, key distribu- tion, feature template creation, cloud data processing and secure data access control. Finally, we compare the pro- posed scheme with other schemes through comprehensive analysis and simulation. The results show that the pro- posed data access scheme is feasible and secure for cloud computing.

For sustainable and profitable livestock production, precision livestock farming necessitates the formulation of optimal husbandry and management practices across various aspects, including tracking individual animal pedigrees, monitoring milk production performance, assessing health status, managing feeding and nutrition, making culling decisions, and implementing selective breeding. Data-driven decision-making is essential in these practices, and comprehensive and efficient record keeping is fundamental to producing the reliable data needed for them. This paper presents the design and development of an RFID-based record management system tailored for small to medium-sized goat farms, specifically implemented at the Small Ruminant Center of Central Luzon State University. The system integrates RFID technology to streamline data capturing and management processes, enhancing the efficiency of routine herd operations such as milking, weighing, and health treatments. The system comprises four primary components: animal identification and data capturing, task management, financial management, and real-time reporting and data analysis. Upon deployment, practical enhancements were made based on real-world usage, including improved security measures, streamlined data input processes, and enhanced user notifications. The system was evaluated by IT experts using ISO/IEC 25010 criteria, receiving high ratings across functionality, performance, and compatibility. This system will contribute to the advancement of record management practices for goat farming, leading to increased production and improved livelihoods for small ruminant farmers in the Philippines. ©2024 IEEE.
