Wireless Networks-on-Chip (WiNoCs) have emerged to solve the scalability and performance bottleneck of conventional wired NoC architectures. However unlike communication in the macro-world, on-chip communication poses several constraints, hence there is the need for simulation and design tools that consider the effect of the wireless channel at the nanotechnology level. In this paper, we present a parameterizable channel model for WiNoCs which takes into account practical issues and constraints of the propagation medium, such as transmission frequency, operating temperature, ambient pressure and distance between the on-chip antennas. The proposed channel model demonstrates that total path loss of the wireless channel in WiNoCs suffers from not only dielectric propagation loss (DPL) but also molecular absorption attenuation (MAA) which reduces the reliability of the system.

Abstract
Recently wireless Networks-on-Chip (WiNoCs) have been proposed to overcome the scalability and performance limitations of traditional multi-hop wired NoC architectures. However, the adaptation of wireless technology for on-chip communication is still in its infancy. Consequently, several challenges such as simulation and design tools that consider the technological constraints imposed by the wireless channel are yet to be addressed. To this end, in this paper, we propose and efficient channel model for WiNoCs which takes into account practical issues and constraints of the propagation medium, such as transmission frequency, operating temperature, ambient pressure and distance between the on-chip antennas. The proposed channel model demonstrates that total path loss of the wireless channel in WiNoCs suffers from not only dielectric propagation loss (DPL) but also molecular absorption attenuation (MAA) which reduces the reliability of the system.

3D model of the Hanging Gardens of Babylon

Taken from http://www.northampton.ac.uk/news/students-present-their-3d-model-of-the-hanging-gardens-of-babylon-to-research-expert/

Hanging Garden VR
Dr Stephanie Dalley, author of The Mystery of the Hanging Gardens of Babylon: An Elusive World Wonder Traced visited the University of Northampton to talk to students about her research and to feedback on their 3D virtual reality model of the gardens.
The Hanging Gardens of Babylon have been described as one of the Seven Wonders of the Ancient World and are believed to have been built around 600 BC, but there is no evidence that the gardens ever existed. Through her research Dr Dalley has suggested that the gardens weren’t actually located in Babylon, but in Nineveh, which is located around 350 miles north of the ancient city of Babylon.
For the last two years, students studying for the BA (Hons) in Games Art have been developing the 3D visualisation of the gardens based on how various researchers have described it. The students presented their work to Dr Dalley, who was able to critique it and give feedback on the representation.
Martyn Simmons, Senior Lecturer in Games Design, commented: “The virtual reality model that the students have been working on is a conversation piece based on various research and ideas and is an on-going project. It was great to have Dr Dalley’s input and for her to see what the students have created so far.
“We are proud that the model will also be on display on the Dutch National Museum from October 2016 until March 2017.”
Ali Al Sherbaz, Senior Lecturer in Computing, commented: “We are encouraging people around the world to participate in this project. I have met many people in both Babylon and the UK who are interested to be part of it. Part of Dr Dalley’s talk was about utilising technology and virtual reality to rebuild the heritages to be available worldwide in museums, schools or colleagues.”

Model-Based Tool Support for Tactical Data Links: An Experience Report from the Defence Domain

(2015) Ajit, S, Holmes, C, Johnson, J, Kolovos, D, Paige, R: Model-Based Tool Support for Tactical Data Links: An Experience Report from the Defence Domain. Software and Systems Modeling, DOI 10.1007/s10270-015-0480-2, ISSN: 1619-1366, Springer Berlin Heidelberg. 

Abstract:
The Tactical Data Link (TDL) allows the exchange of information between cooperating platforms as part of an integrated command and control (C2) system. Information exchange is facilitated by adherence to a complex, message-based protocol defined by document-centric standards. In this paper, we report on a recent body of work investigating migration from a document-centric to a model-centric approach within the context of the TDL domain, motivated by a desire to achieve a positive return on investment. The model-centric approach makes use of the Epsilon technology stack and provides a significant improvement to both the level of abstraction and rigour of the network design. It is checkable by a machine and, by virtue of an MDA-like approach to the separation of domains and model transformation between domains, is open to integration with other models to support more complex workflows, such as by providing the results of interoperability analyses in human-readable domain-specific reports conforming to an accepted standard.

Embedding Computer Forensics within an Undergraduate Programme

An paper on teaching computer forensics was recent published at 7th Annual Teaching Computer Forensics Workshop University of Sunderland on the 10th Nov 2011.


An Embedded Pedagogic Model for Computer Forensics within an
Undergraduate Programme
Authors: Ali Al-Sherbaz , Amir Minai, James Xue, Rashmi Dravid , The University of Northampton


Abstract
The discipline of computer forensics which has a strong mutli-disciplinary background derives from the computing subjects in networking, programming, security and mathematics. Increasing awareness of cybersecurity and emphasising the need for a common vision among students addresses the challenges. The proposed pedagogic model is to embed the computer forensics materials within the undergraduate modules to extend students’ knowledge and skills in a practical context. However, it is also recognised that the depth of knowledge required learning such topics as cyber security should be offered from the underlying principles to their abstraction.


Cyber crimes are on the rise however, Cyber security professionals are in a depressingly low numbers. The lack of focus on this area has certainly resulted in a limited number of experts. Today, there is a demanding need to create new cyber security jobs, which should hopefully bring leverage to the uncontrollable rise of cyber crimes. It is, therefore, necessary to develop the analytical skills which create challenges in building a constructive approach to learning. Also, reflecting the technological fluctuations, it is seen as essential for students to be continuously updated.


The proposed model focuses on the delivery and assessment of certain computing modules, with an evaluation of its efficiency on the use of time and effort in order to satisfy the minimum requirements of the curriculum. The study has also discovered that some of the modules already cover part of computer forensics implicitly. Therefore, highlighting these topics to the students and making them more visible as computer forensics is one of the main objectives. Another objective is to enhance the existing computing modules by dedicating certain amount of lecture time on computer forensic related concepts. The model can then be adopted by Universities when considering developing new modules.


Over  the  last  few  years  there  have  been  large  increases  in  cyber-crimes  which  have  threatened individuals and organisations. To reduce the threat it is imperative that the computing courses within universities increase the level of student awareness by providing them with professional education in computer forensics and cyber-security without the need to create a separate specialised pathway.

    SELF SERVING SOFTWARE FOR THE FAST FOOD INDUSTRY

    Kumuditha Achini Kariyawasam


    As the consumers, we are expecting the best quality products and services
    from the every customer focused industry and when we are considering the
    fast food industry, it has not achieved the full potential of the technological development. After completing the ethnographical research, the developer has realised that the self-serving software model can only achieve the existing and upcoming challenges of this industry.




    Therefore this project based on designing and developing the customer focused self-serving software model for the fast food restaurant. A Large fast food company providede the key system for the entire project and the developer mainly focused the human computer interaction techniques to enhance the usability of the developing system according to the Agile Methodology and Rapid Application Development Methods.


    The final output of the project is the fully functional self-serving software model for the fast food restaurant.  The implementation of the new system development could theoretically improve the efficiency and effectiveness of the industry as well as the high standard customer satisfaction.
