This paper discusses the design and implementation of an RFID-based access control system for use in a University campus. This system's design begins with the design of a power-efficient and cheap passive 125Khz RFID tags and reader antennae using the HFSS software. The key antenna design goals are miniaturization, power efficiency (passive RFID), linear polarization and a narrow beam/gain width....
Direction of arrival estimation has a wide range of applications, both military and commercial, and the search for low complexity methods with high accuracy is an important research area. Many of the well-known methods rely on time averaging of received data to acquire the covariance matrix, essential in the estimation method. Some methods depend on single snapshot in time (single symbol) to generate...
Recently, a considerable attention has been paid for full duplex communication. Full duplex allows transmitting and receiving at same frequency simultaneously. As a result, the spectral efficiency can be increased two times by utilizing this type of communication. Nevertheless, the substantial issue of applying full duplex communication is the self-interference signal. This paper presents a new method...
A comparative study of performance is conducted between two indoor positioning algorithms described in the Literature, the Vector and Ecolocation algorithms. Both use received signal strength (RSS) to implement a radio frequency fingerprinting technique. The experiment is conducted using commercial ray tracing software called Wireless Insite and Matlab. The Vector algorithm performs better than the...
Research has previously demonstrated the positive effects of robotic companion pets, but while this is important from a research perspective, their cost renders their widespread use currently unfeasible. This research seeks to explore the potential of an affordable robot, with a view to making a realistic difference in quality of life for people with dementia and their carers. Early research results...
This paper discusses an approach of the abnormal condition detection of whole blood using piezo-synthetic effects in blood under dynamic external pressure. Three groups of samples having verified chemical and biological conditions were analysed to prove reliable detection: saline, whole blood and whole blood with colorectal cancer as an example of abnormal conditions. The procedure of a discrete differentiation...
The evolution towards mobile networks flat architecture entreat a key-role for IP mobility management in providing the ubiquitous always-on network access services. This paper provides prospects for efficient mobility management in SDN plus mobile network architecture and describe important call control flows in inter system handover scenario. Distribution of gateway function approach has been followed...
In this article interactive visualization techniques for creating virtual objects are considered. We describe the most common methods of photometric transformations between images and a variety of geometric objects contextualized against the backdrop of increased adoption of 360 videos and virtual reality systems. Two techniques, the Harris-Laplacian and the Scale Invariant Feature Transform (SIFT)...
Implementing Cloud Computing technologies requires strategic planning by decision-makers to avoid the risks of adoption, and to gain full competitive advantage. Adopting Cloud Computing is a decision-making process that raises a number of critical issues for organisational management. This paper presents an Holistic Strategic Assessment approach that covers the five main contexts of organisations...
This research work has resulted in the development of a web application that enables discrete event systems simulation to be created using a Petri-object approach. It provides the development of a model in two stages. In the first stage, the dynamics of the classes of objects are created using Petri net. In the second stage, the model is composed of objects with given dynamics. The simulation algorithm...
P2P-based M2M application frameworks have several advantages, such as increased flexibility, efficiency and a lack of single point of failure as compared to centralised approaches. However, there are several security drawbacks which need to be addressed in order to provide the user a secure environment for the provision and usage of M2M applications. This publication presents different security issues...
The further penetration of renewable sources in the grid requires the implementation of energy storages in order to smooth out the variability and intermittent nature of renewables. This paper looks at the possibilities for a storage solution to meet an unprecedented situation of having no power input from renewables or an outage from grid sources for five consecutive days in the highest demand period...
The Radio Frequency Identification (RFID) network planning problem is a critical issue because it strongly has an impact on Quality of Service (QoS) and cost efficiency. However, finding an optimal planning for a large scale RFID network is an NP-hard optimization problem. In this context, metaheuristics provides a natural framework to solve this optimization problem by finding a near optimal solution...
This paper presents a device for hand injury rehabilitation. It allows recognition of different gestures made by a patient and measures such important healing rating as gesture amplitude, movement speed and motion trajectory accuracy. For use with children's rehabilitation it is implemented an ability to control different external devices with different gestures that could be set by using developed...
This publication proposes a novel testing framework for the functional verification of decentralised services and applications in Peer-to-Peer (P2P)-connected Machine-to-Machine (M2M) networks. Besides presented challenges and requirements for testing within distributed environments, a concept for deriving and generating test cases based on a Test Description Language (TDL)-based approach is described...
This paper explores the software and hardware developed for real time process and analysis from an Electrocardiogram ECG. The portable ECG device is used to capture data from the heart and lungs which is automatically converted from analogue to digital signal for further analysis. Via the use of an ECG device, data is collected at two different speeds i.e. walking and running respectively. The collected...
The remarkable growth in wireless communication technologies in recent times has motivated the synergy between wireless systems and medical sciences for improved healthcare services. Several emerging wireless technologies and approaches have therefore been proposed to achieve various efficient monitoring systems for health-related activities. In this paper, localisation of a patient using the ranging...
An arc-shaped planar-monopole two antennas for WLAN and WiMAX application is proposed. The lengths of the two arcs are designed to meet the requirements for the WLAN and WiMAX standard sat 2.45GHz and 3.5GHz respectively. The separation between centers of the two feed lines is 14 mm (0.098 wavelengths at 2.45GHz).A new technique is proposed to reduce the mutual coupling between the two closely-spaced...
