Platforms, frameworks, and other forms of software assets are proliferating in the industry for well-documented reasons. Architects may choose from a wide variety of implementation technologies to realize their envisioned software architecture. Each asset provides the ability to fulfill a set of requirements, and imposes a set of constraints. Given these complex compatibility relationships, it is a non-trivial task to determine how best to utilize candidate assets toward a defined business problem. This task is made harder when multiple stakeholders from various backgrounds contribute to the decision-making process, as often occurs in large projects.By grouping requirements by functional area, and relating them to corresponding candidate technologies, we propose an approach that allows stakeholders to collaboratively reason about the satisfaction of requirements, the compatibility of technologies, and integration risk. The goal is to narrow the initial space of technologies to a smaller number of viable candidate technology sets.

Healthcare software systems are becoming more and more complex since they will be highly integrated to support a wide variety of healthcare workflows (e.g., financial, administration, diagnosis, and treatment). In addition, healthcare software systems will be more safety-critical as they will provide medical decision support for doctors. All of those require systematic and thorough testing of the systems before they are put into use or upgraded. Model-Based Testing (MBT) is an approach to apply formal, explicit system use-models to generate the test cases for testing the system behaviors under different input data sets. This paper describes our experiences in applying this approach to testing some Siemens healthcare software systems. We will report the benefits and challenges in using MBT for testing healthcare software systems.

Although compact mobile devices are convenient and have many advantages, their small screens can present problems. A significant proportion of HTML documents are optimally designed to look best when rendered on high-resolution displays of desktop and laptop computers - not small screen mobile devices. Transcoding solutions exist that can intercept HTML pages and transform them for small screen devices, but as consequence the original visual layout and structure of the page is barely recognizable. Described in this paper is the mobile page attenuator, a proxy-based framework that preserves the view of the document as it was originally intended for the desktop in a form renderable on a small screen device. A scheme for region-based interactivity is also introduced, further ameliorating the need for excessive scrolling in either direction.

Bluetooth is a relatively new wireless technology that holds much promise as an inexpensive, power conserving, pervasive global standard for short-range communication with support for voice, data, ad-hoc networking and LAN access. A scalable LAN access solution based on Bluetooth, called blu21, has been developed by Siemens to support information access via mobile devices in enterprise and public hotspots. In this paper we introduce blu21 then describe an associated dynamic content adaptation service called bluMediator and additional services aimed toward improving the efficacy of the mobile browsing experience.
