Indoor signal propagation characteristics can be difficult to predict accurately. Factors such as building layout and building materials can have a major effect on signal propagation. In this paper we will model indoor signal propagation using lognormal shadowing characteristics. The benefit of this model over others is its simplicity. The accuracy of this model at predicting the relationship between...
In this paper, we are introducing an intelligent valet parking management system that guides the cars to autonomously park within a parking lot. The IPLMS for Intelligent Parking Lot Management System, consists of two modules: 1) a model car with a set of micro-controllers and sensors which can scan the environment for suitable parking spot and avoid collision to obstacles, and a Parking Lot Management...
Wireless Sensor Networks have been widely used by researchers in different personal and organizational applications. Recently, WSN has become the major focus of researchers to establish a secure network against malicious node. The security of WSN can be subjected to threats by attackers. In order to limit these threats on WSNs, Elliptic Curve Cryptography (ECC) introduces great features such as smaller...
Long-Term Evolution (LTE) is a radio access technology. It is a standard cellular network that enables mobile transmission of streaming high definition video in real time. This paper analyzes the development and LTE performance in streaming multimedia through an analysis of the video transmission package performance. Furthermore, we examined the influence of LTE in streaming multimedia through the...
The connecting of physical units, such as thermostats, medical devices and self-driving vehicles, to the Internet is happening very quickly and will most likely continue to increase exponentially for some time to come. Valid concerns about security, safety and privacy do not appear to be hampering this rapid growth of the so-called Internet of Things (IoT). There have been many popular and technical...
Security is the critical subject in wireless sensor networks. Therefore, WSNs are susceptible to several types of security attacks. One reason to attack sensor networks is the limited capacity of sensor nodes. The security attacks could affect the most significant applications in WSNs area such as military surveillance, traffic monitor, and healthcare. Thus, there are different types of detection...
Controlling secure access to web Application Programming Interfaces (APIs) and web services has become more vital with advancement and use of the web technologies. The security of web services APIs is encountering critical issues in managing authenticated and authorized identities of users. Open Authorization (OAuth) is a secure protocol that allows the resource owner to grant permission to a third-party...
Collision Avoidance (CA) systems have been used in wide range of different robotics areas and had extraordinary success in minimizing the risk of collisions. It is a critical requirement in building mobile robot systems where they all featured some kind of obstacle detection techniques in order to avoid two or more objects from colliding. The purpose of this paper is to present an algorithm for performing...
Evaluating the anterior chamber angle with gonioscopy is an essential part of evaluating patients at risk of contracting glaucoma and neovascularization. It also provides useful information for patients with iris abnormalities or a history of trauma or ocular inflammation. Unfortunately, gonioscopy is underutilized by both optometrists and ophthalmologists. There are many symptoms that call for performing...
Electronic capture of patient records, including digital imaging, facilitates: i) collaboration and communication between providers and entities involved in patient care, ii) compilation of lifetime patient histories that are more accessible to treating physicians, and iii) aggregation of population data for evidence-based medicine and creation of decision support tools. The Medicare and Medicaid...
In this work, an efficient digital system is designed using hardware to filter the Electrocardiogram (ECG) signal and to detect the QRS complex (beats). The system implementation has been done by using a Field Programmable Gate Array (FPGA). In the first phase of the hardware system implementation, Finite Impulse Response (FIR) filters are designed for preprocessing and denoising the ECG signal. The...
Scientific data sets usually have similar jobs that are frequently applied to them by different users. In addition, many of these data sets are unstructured and complex, and required fast and simple processing. In order to increase the performance of the existing Hadoop and MapReduce algorithm, it is necessary to develop an algorithm based on the type of data sets and requirements of the jobs. Genomic...
Over the last few decades, telehealth has emerged as another segment of the healthcare continuum. People are now able to gain more control over the care that is provided to them because telehealth technologies allow people to monitor and report the data that is collected to their healthcare providers. It is the providers of healthcare who then interpret the results and take necessary action. This...
As resilient as the human body may appear to be, the aging process is inevitable and takes a physical toll on all bodies, but getting older does not equate to neglecting healthy habits. If anything, as people age it is more important to be vigilant and lead proactive lifestyles. In an effort to increase health awareness and promote a healthier lifestyle Pace University conducted a 7 week pilot study...
Scalable and efficient Medium Access Control (MAC) protocol has been of the paramount significance for boosting the performance of wireless sensor networks (WSNs). In this paper, scalable and efficient medium access control (SE-MAC) protocol is introduced for WSNs. The Goal of SE-MAC is to reduce the communication delay time, channel delay time and control delays caused by acknowledgment packets,...
Physical body signals such as (ECG, EEG) usually interference with high frequency noises, like powerline interference, electromyography (EMG) noise, and equipment's with high vibration which cause wrong reading or effect on our final benefit from [1-2]. One of the most effect method to cancel and reduce all contaminate noise by using adaptive filters which requires an external reference to estimate...
Electricity-operated durable medical equipment (DME), such as ventilators, dialysis machines, and patient monitoring devices, are life-supporting machines used extensively by patients at home. While convenient and economical, at-home use of DME is susceptible to power outages, especially the ones caused by natural disasters that often occur in large area and for a long duration. There is little existing...
The use of low-cost thermopile sensors for aerial vehicle roll angle estimation was investigated as an alternative to GPS reliant navigation solutions. The minimal number of measurements necessary to estimate vehicle roll was determined. A physics-based sensor model was used to investigate the effect on estimate error over sensor field-of-view angle and for nonminimal sensor sets. The bound on error...
Nowadays, analyzing EEG signals has made it easy to diagnose many sleep-related breathing disorders such as Obstructive Sleep Apnea (OSA), which is a potentially serious sleep disorder that affects the quality of human life. This paper introduces an efficient methodology that could be implemented in hardware to differentiate OSA patients from normal controls, based on the Electroencephalogram (EEG)...
