Quality attribute workshops (QAW) provide a method for evaluating the architecture of a software-intensive system during the acquisition phase of major programs. The architecture is evaluated against a number of critical quality attributes, such as availability, performance, security, interoperability, and modifiability. The evaluation is based on test cases that capture questions and concerns ...

The design of microwave filters and multiplexers usually starts with the synthesis of an equivalent circuit for determining the optimal architecture of the device. One can observe that the requirements for filtering devices in the last-generation of communication systems have broadened the area of traditional filter synthesis. In the recent years, many studies have concerned the synthesis of ad...

An empirical study concerning management accounting information on corporate pricing decisions is presented. The study reveals insufficient information quality in organizations. The lack of information quality concerns the relevance of information available to the decision-making sales departments. In particular, too much irrelevant information is supplied by the controlling departments, as wel...

This paper contributes to knowledge on workshops as a research methodology, and specifically on how such workshops pertain to e-learning. A literature review illustrated that workshops are discussed according to three different perspectives: workshops as a means, workshops as practice, and workshops as a research methodology. Focusing primarily on the latter, this paper presents five studies on...

Magnetic resonance (MR) urography has an expanding role as a problem solving tool in treated cancer. Hydronephrosis is common with abdominopelvic neoplasms and whilst the majority are satisfactorily investigated by urography, ultrasound (US), computed tomography (CT), invasive imaging or endourological techniques, some hydronephroses remain unexplained. These may occur in patients with renal im...

Cutaneous cancer is now the most common human malignancy and in the UK 11% of that total is due to malignant melanoma of which probably 80% is related to increased exposure to sunlight. Although it is the least common skin cancer malignant melanoma is the most deadly, and in 1999 it killed over 1600 individuals in the UK. In 2004, in the USA, 55 100 new cases were anticipated. The incidence of ...

The objectives of this presentation are to discuss the clinical role of magnetic resonance (MR) in local and nodal staging of prostate cancer, and to show new developments. The clinical questions are how can we improve with new MR imaging (MRI) techniques: localization, local staging, targeted radiotherapy planning, and nodal staging? Accurate tumour localisation is important for detection of p...

Reconfigurability/tunability has become an essential feature of modern agile RF and future mm-wave apparatuses and systems for wireless communications, sensing and imaging. In the coming decades there will be a paradigm shift towards smart, cognitive and agile wireless sensing (including imaging) and communication systems. The use of mm-wave frequencies will lead to communications systems showi...

Over 60 years of scholarship have been dedicated to describing meaning-making processes through which organisational learning occurs. Recently, researchers considered the creation shared prolonged and co-located interactions situated in context a community. The spread hybrid working has had an adverse impact on several these processes, disrupting knowledge-sharing ecosystems overall. In this ar...
