Android is the primary software platform for mobile, networked devices such as tablets and smartphones. These devices are increasingly used for safety-critical functions that require verification of correct and robust behavior of applications. Such software written for the Android operating system is hard to test because applications are inherently concurrent, applications are usually being driven by asynchronous user input and network events, the application model is not amenable to unit testing, and the availability of sources for many commercial applications is missing. Safety-critical applications require verification by means of systematic exploration of all possible software behaviors. Conventional testing does not guarantee sufficient coverage, especially for concurrent applications.

Enterprise Business Information System (EBIS) Data Warehouse Quality Inspector

A typical data warehouse may contain thousands of tables. Validating the data quality of all data warehouse content is an unmanageable and unmaintainable task if handled in an ad-hoc fashion. This software seeks to ensure that a data warehouse accurately reflects the contents of the business systems that feed it, in turn guaranteeing accuracy of business reports. Data anomalies can occur due to breaks in processes, unexpected changes to business rules, upgrades, unanticipated data relationships, or inadequate testing. Inspecting the data after each batch load for anomalous conditions allows IT to respond quickly to such issues, and to deliver a higher-quality product to end users.

Network Geolocation Technology

This system is difficult to spoof, and does not generate false positives.

A network geolocation technology (NGT) can be used to determine the physical location of a networked Internet user, as well as accurately determine if an Internet user is in fact in the metropolitan service area that the user claims as his/her location. NGT is based on the laws of physics, and operates independent of an IP address lookup or any other pre-existing user network address profiles.

Using Formal Methods for Engineering Embedded Systems

Between 1985 and 1987, a radiation therapy device called the Therac-25 was involved in at least six incidents in which the device delivered massive overdoses of radiation. The patients involved suffered radiation burns and symptoms of radiation poisoning. Three of those patients eventually died, all because of a latent software bug. A race condition had gone undetected. It was a test case no one had thought to define.

PLOT3D 4.1

PLOT3D is an interactive graphics program designed to help scientists visualize computational fluid dynamics (CFD) grids and solutions. Today, supercomputers and CFD algorithms can provide scientists with simulations of such highly complex phenomena that obtaining an understanding of the simulations has become a major problem. Tools that help the scientist visualize the simulations can be of tremendous aid.

Do you see augmented reality as a way of improving design processes?

A report last week concluded that the augmented reality (AR) market is expected to grow from $2.39 billion in 2016 to $61.39 billion by 2023. The research from the Hadapsar, India-based analyst firm MarketsandMarkets cites increasing demand for AR devices and applications in healthcare, retail, and e-commerce sectors.

AR plays a potential role for design engineers looking to model a product directly into an environment. What do you think? Do you see augmented reality as a way of improving design processes?

Requirements Engineering for Safety-Critical Systems

In safety-critical projects, Requirements Engineering is often perceived as a “necessary evil” rather than active support in the development process. Challenges arise between the writing of requirements, categories and levels of abstraction, and the high degree of freedom in Functional Safety Standards, and the practical benefits of effective requirements engineering are lost.
