Several algorithms have been proposed to achi...

abstract: With robots being used extensively in various areas, a certain degree of robot autonomy has always been found desirable. In applications like planetary exploration, autonomous path planning and navigation are considered essential. But every now and then, a need to modify the robot's operation arises, a need for a human to provide it some supervisory parameters that modify the degree of autonomy or allocate extra tasks to the robot. In this regard, this thesis presents an approach to in...

Web forums are a popular way of exchanging information and discussing various topics. These websites usually have a special structure, divided into boards, threads and posts. Although the structure might be consistent across forums, the layout of each forum is different. The way a web forum presents the user posts is also very different from how a news website presents a single piece of information. All of this makes the navigation and extraction of text a hard task for web scrapers. The focus ...

Autonomous relative terrain navigation is a problem at the forefront of many space missions involving close proximity operations to any target body. With no definitive answer, there are many techniques to help cope with this issue using both passive and active sensors, but almost all require high fidelity models of the associated dynamics in the environment. Convolutional Neural Networks (CNNs) trained with images rendered from a digital terrain map (DTM) of the body’s surface can provide a way ...

We propose the use of a personal video navigation history, which records a user's viewing behaviour, as a basis for casual video editing and sharing. Our novel interaction supports users' navigation of previously-viewed intervals to construct new videos via simple playlists. The intervals in the history can be individually previewed and searched, filtered to identify frequently-viewed sections, and added to a playlist from which they can be refined and re-ordered to create new videos. Interval s...

By making a website responsive, its layout and content will adapt to the screen size, no matter if the website is visited from a smartphone or a computer. Designing for a small screen is about compromising since it is only possible to show fairly little content at a time, but still take account for the user experience. One aspect that heavily relies on screen size is navigation on the website. Within this project, different navigation solutions for responsive web design are examined and a suitab...

In this thesis we present a method for achieving real-time view interpolation in a virtual navigation application that uses a collection of pre-captured panoramic views as a representation of the environment. In this context, viewpoint interpolation is essential to achieve smooth and realistic viewpoint transition while the user is moving from one panorama to another. In this proposed approach, view interpolation is achieved by first computing the optical flow field between a pair of adjacent pa...

Guidance is defined as the determination of a strategy for following a nominal path in the presence of o-nominal conditions, disturbances and uncertainties, and the strategy employed is called a guidance law. Variants of Proportional Navigation (PN), such as True Proportional Navigation (TPN) and Pure Proportional Navigation (PPN), have been studied extensively in the literature on tactical missile guidance. In the absence of target maneuvers, in a linear interceptor guidance problem, TPN was sh...

Creating 3D models of our surrounding world has seen a rapid increase in research and development over the last few years. A common method is to use laser scanners. Mapping is done either by ground based systems or airborne systems. With stationary ground-based laser scanning, or terrestrial laser scanning (TLS), it is possible to obtain high accuracy point clouds. But stationary TLS can often be a cumbersome and time-demanding task due to its lack of mobility. Because of this, much research has...

In this thesis, we develop a model predictive control (MPC) scheme for the navigationof multiple quadrotors in an environment with obstacles. The overall controlscheme is decentralized, since each quadrotor calculates its own signal based on localinformation. The MPC constraints take care of collision with the static obstacles,inter-agent collisions as well as input saturations. Firstly, we formulate and solvethe problem using a nonlinear MPC framework, where the agents and the obstaclesare mode...

We propose a novel 3D navigation system for autonomous vehicle path-planning. The system processes a point-cloud data from an rgb-d camera and creates a 3D occupancy grid with adaptable cell size. Occupied grid cells contain normal distribution characterizing the data measured in the area of the cell. The normal distributions are then used for cell classification, traversability and collision checking. The space of traversable cells is then used for path-planning. The ability to work in three-di...

A rapid clearance of a third of the number of Onchocerca lienalis microfilariae injected into Simulium vittatum, a laboratory host, occurred within 2 hr post inoculation (pi) regardless of dose. A second injection, 2.5 hr after the first, resulted in a lower proportion of microfilariae eliminated, suggesting that availability of active factors were reduced after the first inoculation. Microfilariae did not differ in their susceptibility to clearance as microfilariae that were recovered 2 hr pi a...

In image-guided surgical navigation, instruments tools are tracked by a position sensor and their locations rendered along with the patient's anatomy. Conventional methods require an invasive, time-consuming and potentially uncertain process of intra-operative registration of the images to the patient. In a direct navigation system, such an intra-operative registration is replaced with pre-operative patient-independent calibration in a process that determines the relationship between the coordin...

Behavioural, electrophysiological, and anatomical evidence suggests that retrosplenial (RS) cortex (areas RSA and RSG) plays a role in spatial navigation. It has been recently suggested that it is damage to the underlying cingulum bundle (CG) (areas CG and IG), and not RS, tht disrupts spatial place learning. I revisited this issue by comparing the rat strains and lesions used in studies that typically report RS deficits, to those used in studies in which no RS deficit is reported. I found both ...
