One of the location-based services, spatial trajectory prediction, can be used in a variety of purposes such as travel recommendations and traffic control and planning, but at the same time, just like most location-based services, the concern of user privacy is a major issue. Without rigorous privacy protection, users would be reluctant to use the services. This research proposes a privacy-preserving...
For an unmanned aerial system (UAS) to work seamlessly within the national airspace (NAS), it must have a way to sense and avoid any obstacles autonomously. This paper describes a monitoring system that has the ability to monitor in real-time both the hardware and software components of the UAS during flight operations and execute any actions that are necessary to handle or prevent any issues that...
Location-based services (LBS), one of mobile applications, have attracted a great attention recently. This research proposes a location-based service, which predicts a spatial trajectory based on the current and previous trajectories by using a novel matrix representation. Spatial trajectory prediction can be used in a variety of purposes such as travel recommendations and traffic control and planning,...
In this survey paper, we explore different medical imaging techniques used in the diagnosis of breast cancer. We compare their effectiveness, advantages, and disadvantages for detecting early-stage breast cancer. We mainly focuse on X-ray mammography, ultrasound, and magnetic resonance imaging (MRI), as they are the primary imaging modalities used in the clinic for the diagnosis of breast cancer.
In the electromagnetic spectrum, Terahertz (THz) radiation is located between the infrared and microwave regions. As a result of recent advances in THz technology, numerous opportunities have opened up in this part of the spectrum. The THz frequency range stimulates substantial amplitude vibrational modes of molecules. Water has strong absorptions at THz frequencies and water being a major constituent...
Terahertz (THz) radiation sources are increasingly being used in military, defense, and medical applications. The study of the potential effects of THz radiation on biological systems is therefore an important issue in the safe development of a large number of applications. Despite the fact that the general population has not been exposed to this band of the electromagnetic spectrum, a timely assessment...
Image mosaicing has been practiced in several computer vision and scientific research areas. There is a clear indication of the advancement of the state of the art of mosaicing algorithms. However, the methods of quantitative evaluation of mosaicing algorithms are still inadequate. Furthermore, a majority of the previous evaluation methodologies lack a sufficient number of performance metrics, while...
Many students who switch away from an engineering major cite math, specifically calculus, as one of the most influential factors in that decision. This paper presents a method to improve engineering student persistence and learning in calculus without any changes in the current calculus curriculum. The proposed method combines the integration of real world engineering problems into existing Calculus...
Since the introduction of iPhone in 2007, smartphones have become very popular. The high mobility of smartphones has created many applications that are not possible or inconvenient for PCs and servers, even notebooks. One of the mobile applications, location-based services (LBS), has attracted great attention recently. This paper proposes location-based research, which uses location information to...
It has been demonstrated that transmission systems using Turbo codes can achieve performance close to the Shannon limit. Although these codes were introduced two decades ago, their hardware implementations are still challenging because of the complexity of their equations. This paper presents a Field Programmable Gate Array-based implementation of a Turbo Codec system. This system includes an encoder...
This paper describes a combined Pulse Width Modulation (PWM)-Pulse Frequency Modulation (PFM) technique implemented in a Field Programmable Gate Array (FPGA) to control DC-DC converters. This technique changes the mode of operation from PWM to PFM with the change in the load condition. The efficiency of the proposed technique is determined by implementing a DC-DC converter and calculating the conduction...
Since the launch of iPhones in 2007, smartphones become very popular these days. Because of their small sizes and high mobility, smartphones are easily lost or stolen. When people lost their smartphones, they are worried the private data stored in the phones may be revealed to strangers. This research proposes a novel approach for mobile data protection. Mobile usage data is first collected and usage...
Gel electrophoresis, a widely used technique to separate DNA according to their size and weight, generates images that can be analyzed automatically. Manual or semiautomatic image processing presents a bottleneck for further development and leads to reproducibility issues. In this paper, we present a fully automated system with high accuracy for analyzing DNA and proteins. The proposed algorithm consists...
Gel electrophoresis has significantly influenced the progress achieved in genetic studies over the last decade. Image processing techniques that are commonly used to analyze gel electrophoresis images require mainly three steps: band detection, band matching, and quantification and comparison. Although several techniques have been proposed to fully automate all steps, errors in band detection and,...
