This paper presents the design of a system that is aimed to provide a flexible, portable and low cost solution for optical fiber based sensor systems. The field programmable gate array (FPGA) provides the digital logic to implement the system and ability to reconfigure the system operation. It aims to support different optical fiber sensing requirements by the ability to reconfigure the digital circuitry...
In this paper, the design and operation of a sigma-delta modulation based signal generator for the creation of signal waveforms to be used in current mode control of light emitting diodes (LEDs) is presented. The LED is to be used as the light source within an optical fiber sensor (OFS) system and is to be driven with known current waveforms for use within the system. In this paper, the use of pulse...
In this paper, pole-zero estimation, analysis and simplification of the transfer function for a two-stage operational amplifier (op-amp) is presented. The circuit design considered is a folded cascode complementary metal oxide semiconductor (CMOS) op-amp incorporating both Miller and negative Miller frequency compensation. The design was created using a 0.35 µm CMOS fabrication process and analyzed...
In this paper, the design and operation of a sensor system design using radio frequency identification (RFID) and near field communication (NFC) principles is presented. Data and control signals between an external computer and the sensor electronics are provided for using an RFID card or tag and so this interface is both portable and contactless. The sensor electronics would be embedded within a...
This paper presents a novel technique to design a programmable bandwidth single-ended output CMOS operational amplifier using a serial digital interface. The circuit topology enables the programming of the value of a negative Miller capacitance around first amplification stage and programming of the value of a Miller capacitance around the second amplification stage. Therefore, a controllable frequency...
Cataclysmic circumstances around the globe are increasing day by day either because of some severe natural disasters or human faults. Fire occurrences have a place with the latter kind of fiasco, which typically need to do with human mistake. The biggest casualties of fire risk are generally the commercial ventures, processing plants, oil refineries, industries and comparative locales, which essentially...
The need for securing data across the Internet has become a fundamental issue over the last decade. The Internet protocol security (IPSec) standard has been developed as one solution to the problem of end‐to‐end secure communications. IPSec implementation is computationally intensive and can significantly limit the performance of high‐speed networks. To overcome this speed issue, hardware implementations...
The Advanced Encryption Standard (AES) is a symmetric key Block cipher that is used to provide data confidentiality in many embedded systems. Data confidentiality of each information is very important, either the information is related with bank account statements, credit card numbers, trade secrets, government documents or personal information. The confidentiality of a patient's physiological data...
Real-world deployments of Internet of Things (IoTs) applications require secure communication. The IPSec (Internet Protocol Security) is an important and widely used security protocol (in the IP layer) to provide end to end secure communication. Implementation of the IPSec is a computing intensive work, which significantly limits the performance of the high speed networks. To overcome this issue,...
In wireless body sensor networks (WBSNs), sensors continuously monitor human physiological activities using medical sensors, for example, blood pressure, body temperature and electrocardiography (ECG). A WBSN can be used to develop a patient monitoring system. The traditional body sensor networks (BSNs) have limited hardware resources in terms of computational capabilities, data processing speed,...
Widening participation in higher education is a major component of governmental level education policy within Europe. It consists of an attempt to increase not only the numbers of young people entering higher education, but also the proportion from so-called “under-represented groups” (those from lower income families and some ethnic minorities (socio-economically disadvantaged), along with individuals...
Widening participation in higher education has become a major concern for many higher education institutions in order to redress the imbalance that has be created where specific groups in society have over time become underrepresented within higher education. To redress this imbalance, higher education institutions need to set-up and maintain supports to attract more students from these underrepresented...
Remote laboratories have developed to an extent that they are now regularly used in the teaching and learning of the STEM (Science, Technology, Engineering and Mathematics) subjects within higher education institutions. The available resources of these remote laboratories and the user experience are usually designed with ease of access for students who do not have a disability - either a mental impairment...
In this paper, consideration is given to the use of the Digilent Analog Discovery in the teaching and learning of semiconductor devices and circuits. Specifically, an introduction to the characteristics and uses of diodes and transistors will be considered, along with the types of analogue and digital circuits that can be created using diodes and transistors. The features of the Analog Discovery will...
This paper presents a set of initial results from one of the objectives in the EU supported project SALEIE (Strategic Alignment of Electrical and Information Engineering in European Higher Education Institutions) which runs from October 2012 to November 2015. One of the key work packages within the project considers access to students in higher education within the electrical and information engineering...
Cryptographic hash functions have many security based applications, particularly in message authentication codes (MACs), digital signatures and data integrity. Secure Hash Algorithm-3 (SHA-3) is a new cryptographic hash algorithm that was selected on 2nd Oct '12 after a five year public contest organized by the National Institute of Standards and Technology (NIST), USA. This paper provides a unique...
In this paper, consideration is given to accessibility aspects for students with disabilities in electrical and information engineering laboratories who have limited mobility and who would need to access physical electronic and computer engineering laboratories. Specific consideration is given to the use of remote laboratories which are real experiments that are accessed remotely by a user via an...
Education programmes developed within higher education institutions (HEIs) follow a sequence of student activities from first to final year of study and provide the students with a range of appropriate experiences. The structure of the programme is carefully created to provide the students with a suitable education experience in their chosen domain of expertise. The programmes developed need to have...
In this paper, a discussion is presented into ways in which the area of radio frequency identification (RFID) can be introduced to students studying electronic and computer engineering at the university level and different teaching and learning scenarios will be considered. The idea is to consider how to present the engineering aspects of such technology in a meaningful way and which identifies how...
In this paper, the concept for a radio frequency identification (RFID) enabled student workbook is discussed and a prototype system developed. The workbook is a question-answer notebook in traditional paper format in which hand written solutions to student assignments are written. An embedded RFID tag in the workbook is then used for the student to store his/her solution to the attempted assignment...
