Abstract:
This thesis addresses the problem of design and analysis of distributed in-network signal processing algorithms for effcient aggregation and fusion of information in wireless sensor networks. The distributed in-network signal processing algorithms alleviate a number of drawbacks of the centralized fusion approach. The single point of failure, complex routing protocols, uneven power consumption in sensor nodes, ineffcient wireless channel utilization, and poor scalability are among these drawbacks. These drawbacks of the centralized approach lead to reduced network lifetime, poor robustness to

This work investigates the problem of efficiently monitoring and disseminating road traffic information in urban settings using fixed and mobile sensor networks. A key challenge in outdoor urban environments is that bandwidth is a scarce resource.

This thesis proposes two distinct approaches to reducing the communication cost of traffic monitoring: 1) in-network data reduction in the context of fixed sensor networks, and 2) efficie

We then use source coding theorems from information theory to develop three results that aid in WSN design. First, we propose a new top-level design metric for W

Abstract:
Rolling element bearings are used to carry load and reduce friction between moving parts in rotating machines, which play a central role in society and industry, for example in the transportation and energy sectors. It is essential to monitor and maintain the condition of bearings such that machines can operate efficiently and any failures resulting in unplanned stoppages are avoided. Therefore, bearings with embedded sensing capabilities are becoming increasingly common, which makes it possible to consider bearings to be sensor systems that can monitor the condition of rotating machines.

Abstract:
The fields of navigation and motion inference have rapidly been transformed by advances in computing, connectivity, and sensor design. As a result, unprecedented amounts of data are today being collected by cheap and small navigation sensors residing in our surroundings. Often, these sensors will be embedded into personal mobile devices such as smartphones and tablets. To transform the collected data into valuable information, one must typically formulate and solve a statistical inference problem. This thesis is concerned with inference problems that arise when trying to use smartphone sensors

The purpose of this master thesis is to develop a mobile and accurate positioningsystem used in the industry. The system is sensor-based, consisting of anaccelerometer (on a LSM9DS0 breakout board) and three gyroscopes(L3GD20) aswell as a microcontroller development kit(Teensy 3.5). This thesis project involvestheoretical study and the development of a prototype. In particular, the theoreticalstudy has been concerned with investigation of different positioning methods whichincludes sensor limitations, calibrations, sensor fusion and ways to implement thesemethods in an effective manner.A proto

Abstract:
This thesis investigates the possibility to automate testing of PCBs with a sensor system.  This PCB testing is today done manually by placing PCBs in a test fixture that determines its condition. This test requires an operator to wait for the test to complete and then place the PCB in the correct section. If this process can be automated time could be saved and the risk of mishandling PCBs could be reduced. A sensors system is made that consists of an Arduino with micro switches, hall effect sensors, a scanner and a LiDAR. The sensor system is designed to achieve a set of requirements that is
