This report was carried out as a part of the project OPTIVe (Optimized System Integration for Safe Interaction in Vehicles). OPTIVe’s function is to examine, evaluate and show methods and technical solutions for reliable, efficient and cost effective integration of HMI systems
In this report we will talk about Suppression of reverberation in hearing aids. Reverberation is actually a sound degradation which lead to reduced speech intelligibility. For a hearing impaired person putting on a hearing aid, this could cause communication problems and therefore,
Bioinformatics means using computer techniques to evaluate biological data, It continues to be an exceptionally active research field in the last couple of decades. Developments in this field have led to the collection of gigantic amounts of data, and the sheer amount
Cutting and Packing (C&P) issues are usually present in our daily life. Common instances comprise of resource allocation, material cutting, package packing, to mention a few. The C&P dilemma is an optimization challenge for assigning small objects into some large ones. Its
To relight an item under different illumination circumstances, we have to model the reflectance property of its surface elements. Mathematically, the reflectance property of a surface element is actually a spherical function. Its input domain is the spherical surface and the output
The purpose of this master thesis, performed at FOI, was to evaluate a range gated underwater camera, for the application identification of bottom objects. The master thesis was supported by FMV within the framework of arbetsorder Systemstöd minjakt.
Software patterns have been proven as a valuable way to storing a repeatable solution to a commonly occurring problem in software design. A pattern is not a finished design that can be directly formed into program code; instead it is a description how to solve a problem that may occur in many situations
Steganography, meaning hidden writing, is the technique of concealing secret information into another cover-media, such as audio, video, image and text, in such a manner that the very existence of the information is camouflaged. Unlike the goal of cryptography, which prevents the data from illicit access and modification by transforming the secret data into messy and meaningless bit-streams, the aim of steganography is to conceal their very existence such that the embedded data is inaudible or invisible to the grabbers.
A long-period grating formed in a single-mode optical fiber or waveguide can cause light coupling between the guided mode and the co-propagating cladding modes at specific resonance wavelengths and, therefore, produce a transmission spectrum that consists of a series of rejection-bands centered at those wavelengths.
Currently, code-division multiple access (CDMA) technique continues to be a dominant air-interface technology for personal wireless communication systems. Mobile communication systems based on CDMA is always subject to multiple access interference (MAI) problem due to the difficulty in maintaining orthogonality of CDMA signals in a mobile environment.
