This paper describes power optimization techniques applied to a reconfigurable digital finite impulse response (FIR) filter used in a Universal Mobile Telephone Service (UMTS) mobile terminal. Various methods of optimization for implementation were combined to achieve low cost in terms of power consumption. Each optimization method is described in detail and is applied to the reconfigurable filter
This thesis deals with the properties of wheat storage proteins at interfaces. These proteins are the main constituents of gluten and are recognised for their importance in breadmaking. The components studied were gliadin fractions (a-gliadins, b-gliadins, g-gliadins and w-gliadins), the high-molecular-weight glutenin subunit 1Dx5, and a 58 kDa peptide derived from the central repetitive domain of
The aim of this work was to predict the effect of technological parameters on the physical processes of cheesemaking. To this end we developed and modified techniques with which to measure the physical properties of the curd, such as its permeability and its rheological properties. The effects of different factors, such as pH, temperature, the concentration of casein, the geometry of the curd, app
As travellers, we are usually aware that a map is not the territory it represents. However, as researchers, inquiring into practice, are we always aware of the domain within which that practice is situated? Descriptions of practice sometimes suggest that this is not the case. For example, do engineers actually believe that the models they develop and use are reflections of some reality? It is like
In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length. We are therefore able to investigate friction in th
Industry–academia projects exist in complex contexts of var- ious stakeholders, time perspectives, and goals. In order to analyze projects and communicate about them, we have de- fined an “architectural” model for industry–academia collab- oration, inspired by Kruchten’s software architecture model. The model has four views of i) time, ii) space, iii) activ- ity and iv) domain, corresponding to th
Searches for extra dimensions have been made at the four LEP experiments, ALEPH, DELPHI, L3 and OPAL, where different processes have been searched for within both the ADD and Randall-Sundrum scenarios. Since no signs of any signal have been observed the results have been used to set exclusion limits in the corresponding extra dimension models. This talk presents both individual results from the LE
The before/after study of physiological and biochemical parameters was used to delineate the effects of VDT data entry work on operators. Twenty-nine healthy Chinese students were chosen and divided at random into the simple and the complicated data entry group. The subjects were instructed to work as quickly and correctly as possible according to the 'Data Entry Work Programme’ for 150min. Work p
In this presentation will be given an up-date of the status of epitaxially grown III-V nanowires, from the perspective of growth, processing, physics and applications in the areas of nanoelectronics and nanophotonics
