Krishna Researchers from Ohio State University have developed a machine learning method which helps to determine which existing medications could be applied to improve outcomes in diseases for which they have not been prescribed. Drug repurposing – which accelerates the commercialisation of drugs and lowers the risk associated with safety testing – is not a new concept. … Read more
The Singaporean Minister for Home Affairs has confirmed that the state’s police force has the authority to access Covid-19 contact-tracing app data for the purposes of criminal investigations, raising potential privacy concerns. Singapore’s TraceTogether app was developed in less than two months and was among the first Covid-19 contact tracing apps to be launched. The … Read more
Researchers from University College London’s Sainsbury Wellcome Centre have devised a brain-machine interface (BMI) which allows mice to learn to move a cursor to a target using only their brain activity The study sheds light on how the brain represents causally-controlled objects. When a mouse was controlling the cursor, brain activity in the higher visual … Read more
Engineers from Rutgers University have developed a 3D-printed smart gel that changes shape when exposed to light and can be utilised as a colour-changing “artificial muscle”. The smart gel is inspired by the ability of cephalopods such as octopuses, squid and cuttlefish to change the colour and texture of their skins for camouflage and communication. … Read more
A film that effectively evaporates sweat from skin while using the moisture to power wearable electronics has been developed by researchers from the National University of Singapore (NUS). The main components of the thin film are two hygroscopic chemicals – cobalt chloride and ethanolamine. Besides being extremely moisture-absorbent, the film can rapidly release water when … Read more
Digital systems have such a prominent role in everyday life that we refer to the present technological period as the digital age. Digital systems are used in communication, business transactions, traffic control, spacecraft guidance, medical treatment, weather monitoring, the Internet, and many other commercial, industrial, and scientific enterprises. We have digital telephones, digital televisions, digital … Read more
Microplastics have been found to be so light they can be carried on the wind and transported to far-flung parts of the ocean, including those that appear to be clear of the pollutant. Microplastics – which are defined as particles smaller than 5mm in diameter – can stay airborne for hours or days. This … Read more
Test conditions should be able to be linked back to their sources in the test basis, this is known as traceability. Traceability can be horizontal through all the test documentation for a given test level (e.g. system testing, from test conditions through test cases to test scripts) or it can be vertical through the layers of development … Read more
Static analysis tools are generally used by developers as part of the development and component testing process. The key aspect is that the code (or other artefact) is not executed or run but the tool itself is executed, and the source code we are interested in is the input data to the tool. These tools are mostly … Read more
Performed on requirement design or code without actually executing the software or before the code is actually run. Goal of static analysis is to find the defects whether or not they may cause failure. Static analysis find defects rather than failures.
