Functional models explicitly represent the functions of a system and enable teleological reasoning. Structurebehavior-function models of a physical device, for example, specify the device functions and also its internal causal behaviors that explain how the device structure achieves the functions. They enable reasoning about the device teleology in tasks such as adaptive design and redesign. An...

The massive parallel approach of neuromorphic circuits leads to effective methods for solving complex problems. It has turned out that resistive switching devices with a continuous resistance range are potential candidates for such applications. These devices are memristive systems nonlinear resistors with memory. They are fabricated in nanotechnology and hence parameter spread during fabricati...

When designing a device, the final product of the design process is usually considered to be a physical specification of a device. However, the design of the causal mechanism underlying the physical specification, i.e. how the device is intended to work to achieve its function, is a product just as important as the physical specification, if not more. Capturing this knowledge of causal mechanis...

The emergence of software-intensive systems connecting physical devices to network-based applications involves new design challenges. As an example, flexible manufacturing systems composed of multiple networked devices in interaction with the physical world, are subject to imprecision and to unpredictable breakdowns. Applications and control software are therefore highly complex, and must opera...

In the mobile wireless industry, system size and cost are important factors for having a competitive product. Because of this, in the future system-on-chip (SOC) solutions are likely to emerge. For wireless communications products, this means that the power amplifier (PA) needs to be integrated with the rest of the analog and digital circuitry. This thesis has experimentally studied the suitabi...

The project envisages the implementation of an e-payment system utilizing FIPS-201 Smart Card. The system combines hardware and software modules. The hardware module takes data insertions (e.g. currency notes), processes the data and then creates connection with the smart card using serial/USB ports to perform further mathematical manipulations. The hardware interacts with servers at the back f...
