Résumé :

Mapping, localization, and path-planning are three fundamental problems of robotic. Robot needs a map to perform actions like path-planning. When positioning system is not available, the map is also used for localization. A lot of researches have been done in this area. And newly emerging ranging sensors, like Kinect and TOF camera, have widen people’s choices and greatly enhanced innovative ideas in robot mapping. The price of these sensors is not very high and the performance is decent, which makes low cost, high performance mobile robot solution possible. In this thesis, different existing

Stereo vision uses two adjacent cameras to create a 3D image of the world. A depth map can be created by comparing the offset of the corresponding pixels from the two cameras. However, for real-time stereo vision, the image data needs to be processed at a reasonable frame rate. Real-time stereo vision allows for mobile robots to more easily navigate terrain and interact with objects by providing both the images from the cameras and the depth of the objects. Fortunately, the image processing can be parallelized in order to increase the processing speed. Field-programmable gate arrays (FPGAs) ar

Today companies (especially large companies whose employees make a lot of international business trips) often have very large telephone bills. While international roaming technically works with GSM, the cost of phone calls from one country to another are often much higher than calls within a country. Despite political pressure to reduce the costs of roaming within the European Union, the cost of phone calls from one country to another are often quite expensive.

A number of housing institutions were established , various pieces of legislation were passed and housing subsidies were provided. However, housing backlogs remain a challenge.

Relative localization determines the position of an object based on its previously known location and through sensors that determine speed and heading. Examples of relative positioning sensors incl

The conditions of visibility of a user moving through an outdoor or indoor environment affect his safety. In both environments it is fundamental to guarantee a sufficient visibility in order to avoid possible collisions. In the specific case of urban roads the available sight distance (ASD) is that part of the roadway ahead which is visible to the driver and should be of sufficient length to allow a vehicle to stop before colliding with a stationary object. Unfortunately, the estimation of the ASD is still carried out on 2D maps or digital terrain models (DTM). Furthermore, it is very complica

Many surveying engineering applications require the knowledge of the orientation parameters of instruments. One can use inertial measurement units (IMUs) to determine that. IMUs are combinations of several inertial sensors and comprise at least an accelerometer and a gyroscope. Therefore, they can detect accelerations and angular rates in a three-dimensional space. As micro-electro-mechanical systems, the sensors are increasingly getting smaller and lighter, but without being reduced in their accuracy. The smaller size facilitates diverse placing of the sensors, which allows a variety of uses.

Résumé :

The main topic of this work is the acoustical characterisation and the comparison calibration of a new low cost prototype of a pressure-velocity probe based on MEMS and CMOS technologies. The development during the last years of micro sensors using the double hot-wire anemometric transduction principle, has permitted to directly measure the velocity of the air particle, thus giving a fundamental contribution to the intensimetric measurements. This in turn required a more deep study of the calibration techniques as at least two acoustical signals (pressure and axial velocity) have to be p

Résumé :

Den här uppsatsen beskriver processen av att skapa en plattformsoberoende mobilapplikation för att koppla upp mobila enheter mot trådlösa sensorer med hjälp av Bluetooth Low Energy, samla in data från uppkopplade sensorer och ladda upp den insamlade datan till en molnlagringstjänst. Allt eftersom konsumenter och forskare använder fler sensorer och andra Bluetooth-enheter, [1] ökar behovet av simplare och standardiserade lösningar för att arbeta med dessa. En litteraturstudie har genomförts där information om närliggande forskning insamlats och viktig information om de nödvändiga mjukvarukompon

Résumé :

The study is based on the context of project management; the discipline which employs skills and knowledge to achieve project goals through various project activities. The study concentrates on project management applications to deliver low cost houses (LCH) in the Metsimaholo Local Municipality (MLM). The main purpose of project management application is to enable project managers to track the progress of a project that they are working on. Institutions working on a very large project require project management applications to give periodic updates on the progress of the work that is being do

Résumé :

Heritage Building Information Modelling is strongly connected with the need for accurate surveys, both because BIM models are not usually available and because of the historical buildings’ peculiarity. But acquiring those data demands the involvement of additional costly stakeholders, and that limits the widespread use of LiDAR technologies. New smart devices supplied with this technology may allow customers to acquire point clouds with a different approach, giving us more and more possibilities of easily acquiring a point cloud, possibly omitting the use of expensive equipment and the stakeho

Résumé :

Although typically associated with the provision of low-cost holiday accommodation, for over 30 years city-based caravan parks have provided an unrecognised source of permanent housing to the lower end of the market. Due to their often dilapidated condition and the demographic profile of their residents, caravan parks do not fit within the Australian housing ideal and are often considered enclaves of despondency. Residents are subject to harsh stereotypes and are often referred to as ??trailer trash?? ?? a tag which originated in the USA. However the reality is that caravan parks provide sign

Résumé :

Inspection methods for satellites post-launch are currently expensive and/or dangerous. To address this, BYU, in conjunction with NASA, is designing a series of small satellites called CubeSATs. These small satellites are designed to be launched from a satellite and to visually inspect the launching body. The current satellite revision passively tumbles through space and is appropriately named the passive inspection cube satellite (PICS). The next revision actively maintains translation and rotation relative to the launching satellite and is named the translation, rotation inspection cube sate

Résumé :

The overall aim of the research reported here was the development of a simple, low-cost passive solar heating system for operation in the Portuguese climate. The performance of this device is critically dependent on the rate of convective heat exchange across the cavity behind the heater plate. Both computational and experimental studies of the heat transfer characteristics of this new storage device, have been conducted. An experimental installation in full scale was designed and constructed to enable the measurement of local heat transfer rates. Computer simulations of the laminar flow under

Résumé :

Respiratory motion induces uncertainty in External Beam Radiotherapy (EBRT), which can result in sub-optimal dose delivery to the target tissue and unwanted dose to normal tissue. The conventional approach to managing patient respiratory motion for EBRT within the area of abdominal-thoracic cancer is through the use of internal radiological imaging methods (e.g. Megavoltage imaging or Cone-Beam Computed Tomography) or via surrogate estimates of tumour position using external markers placed on the patient chest. This latter method uses tracking with video-based techniques, and relies on an assu
