SensorCloud: Towards the Interdisciplinary Development of a Trustworthy Platform for Globally Interconnected Sensors and Actuators
Although Cloud Computing promises to lower IT costs and increase users'
productivity in everyday life, the unattractive aspect of this new technology
is that the user no longer owns all the devices which process personal data. To
lower scepticism, the project SensorCloud investigates techniques to understand
and compensate these adoption barriers in a scenario consisting of cloud
applications that utilize sensors and actuators placed in private places. This
work provides an interdisciplinary overview of the social and technical core
research challenges for the trustworthy integration of sensor and actuator
devices with the Cloud Computing paradigm. Most importantly, these challenges
include i) ease of development, ii) security and privacy, and iii) social
dimensions of a cloud-based system which integrates into private life. When
these challenges are tackled in the development of future cloud systems, the
attractiveness of new use cases in a sensor-enabled world will considerably be
increased for users who currently do not trust the Cloud.Comment: 14 pages, 3 figures, published as technical report of the Department

Design Challenges for GDPR RegTech
The Accountability Principle of the GDPR requires that an organisation can
demonstrate compliance with the regulations. A survey of GDPR compliance
software solutions shows significant gaps in their ability to demonstrate
compliance. In contrast, RegTech has recently brought great success to
financial compliance, resulting in reduced risk, cost saving and enhanced
financial regulatory compliance. It is shown that many GDPR solutions lack
interoperability features such as standard APIs, meta-data or reports and they
are not supported by published methodologies or evidence to support their
validity or even utility. A proof of concept prototype was explored using a
regulator based self-assessment checklist to establish if RegTech best practice
could improve the demonstration of GDPR compliance. The application of a
RegTech approach provides opportunities for demonstrable and validated GDPR
compliance, notwithstanding the risk reductions and cost savings that RegTech
can deliver. This paper demonstrates a RegTech approach to GDPR compliance can
facilitate an organisation meeting its accountability obligations
A Sensing Error Aware MAC Protocol for Cognitive Radio Networks
Cognitive radios (CR) are intelligent radio devices that can sense the radio
environment and adapt to changes in the radio environment. Spectrum sensing and
spectrum access are the two key CR functions. In this paper, we present a
spectrum sensing error aware MAC protocol for a CR network collocated with
multiple primary networks. We explicitly consider both types of sensing errors
in the CR MAC design, since such errors are inevitable for practical spectrum
sensors and more important, such errors could have significant impact on the
performance of the CR MAC protocol. Two spectrum sensing polices are presented,
with which secondary users collaboratively sense the licensed channels. The
sensing policies are then incorporated into p-Persistent CSMA to coordinate
opportunistic spectrum access for CR network users. We present an analysis of
the interference and throughput performance of the proposed CR MAC, and find
the analysis highly accurate in our simulation studies. The proposed sensing
error aware CR MAC protocol outperforms two existing approaches with
considerable margins in our simulations, which justify the importance of
considering spectrum sensing errors in CR MAC design.Comment: 21 page, technical repor
Incorporating Agile with MDA Case Study: Online Polling System
Nowadays agile software development is used in greater extend but for small
organizations only, whereas MDA is suitable for large organizations but yet not
standardized. In this paper the pros and cons of Model Driven Architecture
(MDA) and Extreme programming have been discussed. As both of them have some
limitations and cannot be used in both large scale and small scale
organizations a new architecture has been proposed. In this model it is tried
to opt the advantages and important values to overcome the limitations of both
the software development procedures. In support to the proposed architecture
the implementation of it on Online Polling System has been discussed and all
the phases of software development have been explained.Comment: 14 pages,1 Figure,1 Tabl
Mobile Communication Networks and Digital Television Broadcasting Systems in the Same Frequency Bands â Advanced Co-Existence Scenarios
The increasing demand for wireless multimedia services provided by modern communication systems with stable services is a key feature of advanced markets. On the other hand, these systems can many times operate in a neighboring or in the same frequency bands. Therefore, numerous unwanted co-existence scenarios can occur. The aim of this paper is to summarize our results which were achieved during exploration and measurement of the co-existences between still used and upcoming mobile networks (from GSM to LTE) and digital terrestrial television broadcasting (DVB) systems. For all of these measurements and their evaluation universal measurement testbed has been proposed and used. Results presented in this paper are a significant part of our activities in work package WP5 in the ENIAC JU project âAgile RF Transceivers and Front-Ends for Future Smart Multi-Standard Communications Applications (ARTEMOS)â
Applications of lean thinking: a briefing document
This report has been put together by the Health and Care Infrastructure Research and Innovation Centre (HaCIRIC) at the University of Salford for the Department of Health.
The need for the report grew out of two main simple questions,
o Is Lean applicable in sectors other than manufacturing?
o Can the service delivery sector learn from the success of lean in manufacturing and realise the benefits of its implementation?The aim of the report is to list together examples of lean thinking as it is evidenced in the
public and private service sector. Following a review of various sources a catalogue of evidence is put together in an organised manner which demonstrates that Lean principles
and techniques, when applied rigorously and throughout an entire organization/unit, they can have a positive impact on productivity, cost, quality, and timely delivery of services
