This paper proposes a simple Wireless Sensor Network (WSN)-based water level and water quality monitoring system for fish ponds. The proposed architecture uses RGB color sensors and provides a low cost and real-time monitoring system to grow healthy fish and avoid anomalies such as overflow or low water level and the death or disease of fishes for...

This paper presents a speech-based speaker identification system an efficient approach for selection of acoustic parameters closely related to the vocal track shape of the speaker. Speech endpoint detection algorithm is developed in order to discard the room noise and non-speech signal to achieve high accuracy of the system. Windowing and fast Four...

Data sharing is critical due to the possibility of privacy breaches. In contrast, it is very important to design and implement public-spirited policies to expedite effective services and development (e.g., public health care). This research proposes a randomization algorithm for data sanitization that satisfies \(\epsilon \)-differential privacy to...

In the recent past, there has been a tremendous increase of large repositories of data, examples being in healthcare data, consumer data from retailers, and airline passenger data. These data are continually being shared with interested parties, either anonymously – for research purposes, or openly by financial or insurance companies, for decision-...

The concept of privacy is expressed as release of information in a controlled way. Privacy could also be defined as privacy decides what type of personal information should be released and which group or person can access and use it. Privacy Preserving Data Publishing (PPDP) is a way to allow one to share anonymous data to ensure protection against...

The goal of this research is to evaluate the use of English stop word lists in Latent Semantic Indexing (LSI)-based Information Retrieval (IR) systems with large text datasets. Literature claims that the use of such lists improves retrieval performance. Here, three different lists are compared: two were compiled by IR groups at the University of Gl...

The primary purpose of an information retrieval (IR) system is to retrieve all the relevant documents, which are relevant to the user query. Latent Semantic Indexing/Analysis (LSI/LSA) based ad hoc document retrieval task investigates the performance of retrieval systems that search a static set of documents using new questions. Performance of LSI...
