This paper presents a novel design of microstrip-fed pentagon patch monopole antenna for ultra wideband (UWB) applications. This antenna consists of a pentagon patch with suitable dimensions on the upper side of a dielectric substrate; a 50-Ω microstrip feed line and a slotted ground plane. Numerical analysis for the antenna dimensional parameters using CST Microwave Studio is performed and presented. The radiation characteristics of the proposed antenna such as radiation pattern, gain, impedance bandwidth are investigated. The proposed antenna provides a compact size, an UWB frequency range of 3.6-14.7 6GHz (121.6% relative bandwidth), and a maximum gain of 4dBi. These features including the good radiation characteristics of the antenna satisfy the requirements of UWB systems.

The paper considers possible future changes based on what is, to what could be within the next ten years and the possible social, legal and ethical considerations. This ranges from the Internet of Things in the home and garden, to changes of entertainment, sport, travel and marketing. Predicted changes in technology supported learning, and the effect it could have on Higher Education globally are considered. Possible changes to our lifestyle relating to day-to-day living, medical intervention and potential legislation are discussed, for both individuals and organisations.

Physical layer network coding (PNC) is a promising technique used to improve the network throughput in a wireless two-way relay (TWR) channel. In this paper, the PNC technique is embraced for a TWR-free space optical (FSO) communication link for the full utilization of network resources. Such a scheme is particularly useful in situations where multiple nodes wish to exchange their information but there is no direct link between them. Compared with a traditional relay-assisted FSO link, the new scheme uses two phases in a round loop for a TWR transmissions link. We present simulation results for the bit error rate (BER) performance of the proposed system considering the effect of both the atmospheric turbulence and the path loss using subcarrier intensity modulation binary phase shift keying (SIM-BPSK). The result shows that for the TWR FSO link based PNC technique under an atmospheric channel with a weak fading strength of 0.3, a BER of 10-4 is achieved at a signal-to-noise ratio (SNR) of ~25dB.

Research in art and design involves the knowledge and understanding associated with creative works. Practice-led research is also an integral part of art and design. All these areas have been subject to ongoing discussion and debate. One of the current challenges is to produce models that facilitate and enable the development and advancement of research within art and design. However, these models must also synchronise with institutional, national and international frameworks for research development, evaluation, and assessment. The latter can have implications for faculty advancement and also formulaic allocations of research funding across the sector. Practice-led and practice-based research have also generated substantial discussion in terms of seeking a consensus on what is appropriate for developmental purposes and academic assessment. In addition, this area also needs evaluation methods which are fair and consistent across different types of practice. The current situation is that works in these areas are assessed, various types of metric are compared and evaluated, and a proposal is made for the inclusion of metrics alongside the development and use of research models for the development of research. It is argued that deeper analyses of, and more enlightened interdisciplinary approaches to, this are clearly needed.

Basically, the computer-based face recognition area is very challenging, especially when it comes to recognizing objects and images under different illumination conditions. One effective way to solve this problem is to examine the extent to which features remain available for extraction in differing illumination conditions. This paper studies the effect of different illumination conditions on feature extraction in improving the recognition of images. The Discrete Wavelet Transformation technique is used for feature extraction under different types of illumination. Based on the results of our experiments on the collected data set, it is concluded that features remain the same i.e. they are not affected by illumination conditions. It is also concluded that when features are extracted, light only affects the smooth areas of the face.

In this paper we review a class of the Continuous Phase modulation (CPM), namely, the Quaternary Frequency Shift Keying (CP-QFSK) signaling and investigate its suitability for the application in mobile radio systems. This type of modulation renders its self as a spectrally efficient scheme that is currently used in a wide variety of applications ranging from communications systems to sonar, geophysics, and biomedicine, etc. It is exhibited herein that this scheme outperforms its MSK and QPSK counterparts in terms of bandwidth occupancy due to its spectral containment. An extensive survey of research material is provided and some of the CP-QFSK system applications in various realms are highlighted. It is concluded that this signaling scheme due to its spectral efficiency is a viable and promising modulation scheme particularly in the multichannel systems of communications.

This work aims is to offer an assessment process to support architectural decisions in the derivation of specific products of a Software Product Line (SPL) family according to customer requirements, from an optimal feasible solution among a set of feasible solutions. The approach starts from a reference architecture (RA) constructed by a bottom-up process from existing products in a domain. This RA has imbedded the domain knowledge on architectural style(s), main functionality and quality properties. Due to the difficulty of measuring quality properties at architecture design stage, an heuristic is proposed to derive an optimal feasible solution from the weights assigned to architectural choices based on this knowledge and customer requirements. Our results, that are applied to the Integrated Healthcare Information System domain, offer a practical and straightforward way of deriving SPL products that can be partially automatized, and can also be useful from a didactical point of view, to show a complete product derivation process from RA that is often missing to illustrate known approaches.

SPICE based circuit simulation is one of the most important parts of IC design flow. The original SPICE algorithm is very slow and most of EDA companies use different approaches to make simulation faster. Most of these approaches work so that simulator works much faster but obtained solution is less accurate. This is why it is so important to develop new algorithms for transistor level IC simulation speed up with saving of SPICE accuracy. This work reports on attempt to accelerate simulation without accuracy loss.

The impact of plug-in electric vehicles on urban power grids is a major issue for distribution network operators. To avoid a reduction in quality of electricity the operation of electric vehicle charging stations should be coordinated. The paper presents a model of a Smart Control System aimed to coordinate the charging stations and bring benefits to both the power network operator and EV users. The model has been developed in AnyLogic software environment using agent-based and discrete approaches. Two different control strategies were simulated to validate the proposed model. The first strategy aimed to provide equal load to all charging stations. The second strategy focused on bringing EV drivers to the nearest charging station. It was shown that the first strategy is more efficient compared to the second strategy if the cars' flow rate is low.
