Abstract:

Cell phones are the most prevalent computing devices. They come pre-loaded with many different functions such as a digital camera, a mobile web browser, a streaming media player, games, GPS navigation, and more. However, if the banks have their way, the cell phone may become the preferred method of payment for everyday purchases. When that happens, there will be a need to securely send and store the receipt information so that they can be quickly analyzed. This thesis will demonstrate the use of a Digital Receipt system to manage transactions using Bluetooth technology to communicate bet

Abstract:

Важное место при проектировании цифровых систем управления (ЦСУ) занимает задача разработки алгоритма работы цифрового вычислительного устройства (ЦВУ) по выработке управляющего воздействия на объект управления, способного обеспечить на выходе системы переходной процесс с оптимальным соотношением всех его прямых показателей качества. Наиболее распространенным критерием выбора алгоритмов работы ЦВУ при синтезе ЦСУ можно считать критерий быстродействия, позволяющий сформировать закон работы цифрового регулятора таким образом, что дискретная переходная характеристика системы будет иметь вид устой

Abstract:

Handheld devices have a limited amount of screen real estate. If a handheld device could take advantage of larger screens, it would create a more powerful user interface and environment. As time progresses, Moore's law predicts that the computational power of handheld devices will increase dramatically in the future, promoting the interaction with a larger screen. Users can then use their peripheral vision to recognize spatial relationships between objects and solve problems more easily with this integrated system. In the spillable environment, the handheld device uses a DiamondTouch Table, a

Abstract:

In a heavy vehicle, internet connection is not reliable, primarily because the truck often travels to a remote location where network might not be available. The data generated from the sensors in a vehicle might not be sent to the internet when the connection is poor and hence it would be appropriate to store and do some basic computation on those data in the heavy vehicle itself and send it to the cloud when there is a good network connection. The process of doing computation near the place where data is generated is called Edge computing. Scania has its own Edge computation solution, which

Abstract:

Powerful, handheld computing devices have proliferated among consumers in recent years. Combined with new cameras and sensors capable of detecting objects in three-dimensional space, new gesture-based paradigms of human computer interaction are becoming available. One possible application of these developments is an automated sign language recognition system. This thesis reviews the existing body of work regarding computer recognition of sign language gestures as well as the design of systems for speech recognition, a similar problem. Little work has been done to apply the well-known architect

Esta técnica consiste na obtenção de múltiplas imagens (cortes) do volume a reconstruir, permitindo dessa forma um diagnóstico mais eficaz, uma vez que os vários tecidos não se encontram sobrepostos numa imagem 2D. Os algoritmos de reconstrução de imagem usados em DBT são bastante similares aos usados em Tomografi

Abstract:

Cybercrime and related malicious activity in our increasingly digital world has become more prevalent and sophisticated, evading traditional security mechanisms. Digital forensics has been proposed to help investigate, understand and eventually mitigate such attacks. The practice of digital forensics, however, is still fraught with various challenges. Some of the most prominent of these challenges include the increasing amounts of data and the diversity of digital evidence sources appearing in digital investigations. Mobile devices and cloud infrastructures are an interesting specimen, as they

Abstract:

Common thought about cinema calls to mind an audience seated in a darkened theatre watching projected moving images that unfold a narrative onto a single screen. Cinema is much more than this. There is a significant history of artists experimenting with the moving image outside of its familiar setting in a movie theatre. These investigations are often referred to as "expanded cinema". This dissertation proposes a genre of expanded cinema called haptic cinema, an approach to interactive narrative that emphasizes material object sensing, identification and management; viewer's interaction wi

Abstract:

With the development of VLSI and wireless communication technology, portable devices such as personal digital assistants (PDAs), pocket PCs, and mobile phones have gained a lot of popularity. Many such devices incorporate a speech recognition engine, enabling users to interact with the devices using voice-driven commands and text-to-speech synthesis. The power consumption of DSP microprocessors has been consistently decreasing by half about every 18 months, following Gene's law. The capacity of signal processing, however, is still significantly constrained by the limited power budget of these

Abstract:

As increasing functionality in mobile devices leads to rapid battery drain, energy management has gained increasing importance. However, differences in user’s usage contexts and patterns can be leveraged for saving energy. On the other hand, the increasing sensitivity of users’ data, coupled with the need to ensure security in an energy-aware manner, demands careful analyses of trade-offs between energy and security. The research described in this thesis addresses this challenge by 1)modeling the problem of context-adaptive energy-aware security as a combinatorial optimization problem (Context

Abstract:

All optical fields that we encounter in nature or in the laboratory have random fluctuations. Although light emerging from lasers can be considered as “well-behaved” electromagnetic fields, that is certainly not the case of natural sources such as stars. Thus, they must be treated statistically using the theory of coherence, in particular, second-order statistics. The Mutual Coherence Function (MCF) and the Cross-Spectral Density Function (CSDF) are central quantities in the space-time and space-frequency domains, respectively, in the theory of coherence. Both quantities are connected through
