Using Multiple On-Site Markers to Create Large-Scale Augmented Reality Experiences on Smartphones

Augmented Reality (AR) tracking for mobile devices is not realiable in environments where large virtual content, such as an entire virtual building, is to be displayed to the user. This paper presents a study on how multiple on-site markers can be used to better align the virtual scene to the real-world environment to improve large-scale AR...

The trade-offs of RISC-V's lack of the Scaled Index Addressing mode

This paper presents a preliminary study of the set of trade-offs of UC-Berkley’s RISC-V instruction set architecture experiences, due to its lack of the Scaled Index addressing mode. The strong majority of the popular Instruction Sets such as x86, ARM, MIPS and PowerPC include relatively complex ways to calculate memory addresses (addressing...

Scaling Limits of Active Particles

In this thesis, the diffusive limit of active particle motion in R^d is studied via a technique based on homogenisation. Thereafter, this study is extended to active particle motion on a Riemannian manifold. <br/><br/>Furthermore, as an application of active particle motion, a connection is made with the Dirac equation. On the basis of...

Reflections of waves in infinite strings due to mass-spring-damper attachments

In this paper, it is analysed how an infinite cable behaves when a wave from the right hits a TMD system attached to it. The TMD system consists of a mass M1, a spring with stiffness K, a damper with coefficient C and a second mass M2. The cable has a tension T. Then it is investigated what happens when a wave goes through the cable and hits...

Analysis of the response of a simply supported microbeam subject to an electric actuation

In this research a study of the response of a simply supported microbeam subject to an electric actuation is presented. A perturbation method called the method of multiple scales is explained and used to solve our problem. A model concerning the mid-plane stretching and an electric force with a direct and alternating current component is...

Micro-scale effects of stylolite orientation on the motion of tensile failure: A study analyzing strain fields of stylolite limestones using Particle Image Velocimetry

Many laboratory tests of samples where the rock fractures are based on<br/>meso-scale (cm) characterization of effective ‘intact’ strength parameters neglecting the microstructure effects. Understanding fracturing processes at<br/>micro-scale (mm) will require models with microstructure data. However,<br/>data is lacking on micro-scale.<br/...

Reflections of waves induced by a nonlinear spring at the boundary

In this thesis the nonlinear spring system is considered. This system contains a semi-infinite string that is modelled by the wave equation with a pair of inititial conditions and a nonlinear boundary condition. The goal of this thesis is to find a good approximation of this system. Furthermore, the behaviour of the string is studied by plotting...

Effect of Mineral Scaling on Geothermal Wells: Carbonate Scaling

As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly. [3]<br/>In order to overcome this fast increase, the human...

Scaling limit of the odometer of correlated Gaussians on the torus

In the divisible sandpile model, we consider a collection of i.i.d. Gaussian heights on a finite graph. It was shown by Levine et al. (2015) that the odometer function in this case equals a discrete, bi-Laplacian field. Subsequently, Cipriani et al. (2016) proved that the scaling limit of the odometer is a continuum bi-Laplacian field, this time...

On rain-wind induced vibrations of an oscillator with a time-varying mass

This report will study an oscillator with time-varying mass under the influence of rain-wind induced vibrations. The vibrations will satisfy an initial value problem with a nonlinear ordinary differential equation. The multiple time-scale perturbation method is used to solve the initial value problem. As the mass is set periodic in time with...

Feasibility study hyropower plant Vila Volta, Brazil

A remote guesthouse in the Brazilian province of Rio de janeiro is using electricity from the nuclear fed power grid. The owner would like to change the energy supply from nuclear to hydropower if a hydropower plant would produce enough energy to keep the guesthouse running. A small hydropower plant could possibly produce enough energy for the...
