De rol van de Eerste Kamer is het toetsen van wetten op uitvoerbaarheid. Wim Voermans, hoogleraar Staatsrecht, zegt voor NPO Radio1 dat de Eerste Kamer nu te veel een politieke rol in plaats van een controlerende rol vervult.

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

Patterned detectors are an existing technology that can be found in almost all color cameras.

Big Science, commonly defined as conventional science made big in three dimensions, namely organizations, machines, and politics, brings a plethora of different stakeholders together, often for a long period of time. This includes policymakers, scientists, (scientific) managers as well as local “host”…

By training with virtual opponents known as computer generated forces (CGFs), trainee fighter pilots can build the experience necessary for air combat operations, at a fraction of the cost of training with real aircraft.
