The effect of surface structures on the dynamics of wetting was investigated through measurements of the dynamic contact angle and spreading velocity of oil droplets spreading over surfaces with parallel and gridlike V-shaped channels. A rim of liquid was observed to spread out in the channels ahead of the dropfront after a short time of spreading (seconds). The characteristics of the rim were inv

The paper provides an attempt to direct the research in the area of venture capitalist and the board of directors in SMEs. Issues about boards in venture capital-backed technology based industrials are explored, and various research designs are used to meet different research questions. Empirical results indicate that venture capital firms purposefully use boards in the portfolio firm, and boards

The problem addressed in this paper is that of determining the environmental aspects of a transport relation. This problem is addressed from a transport purchasing perspective and in respect of high volume, low value cargo. The research has been both case study inspired as well as action research oriented. The model was developed in a company where the researcher actively participated in its devel

Water vapor sorption isotherms are essential data in models to predict the service life of the cement based structures. The knowledge about sorption isotherms in the presence of supplementary cementitous materials (SCMs) is limited. This study investigates the influence of water to cement ratio (0.4, 0.5 and 0.6), and the presence of two SCMs (70% slag and 10% silica fume) on sorption isotherm in

In this paper, we present a method for estimation of the fundamental frequencies, or pitches, of several periodic sources. This difficult estimation problem occurs, for example, in speech and audio processing whenever multiple speakers or tones are present. The presented method is an extension of a recently proposed method for estimation of the fundamental frequency of a set of harmonically relate

BEAN is a recent stream cipher proposal that uses Feedback with Carry Shift Registers (FCSRs) and an output function. There is a sound motivation behind the use of FCSRs in BEAN as they provide several cryptographically interesting properties. In this paper, we show that the output function is not optimal. We give an efficient distinguisher and a key recovery attack that is slightly better than brut

n this paper a hardware architecture for an OFDM synchronizer is presented. The proposed synchronization unit can be used in any OFDM system that uses a cyclic prefix. The algorithm is based on the correlation introduced by the cyclic prefix, which is exploited in the time domain where both time and frequency offset are estimated simultaneously. The synchronization unit also performs frequency cor

Work place design based on traditional ergonomic science has, to a large extent, been delimited by information collected from studies of individual human beings. This research approach has not been proven to influence industry shop floor work to an extent corresponding to what could be expected from research efforts (Winkel and Westgaard, 1995). Thus the practitioners are left to decide about the

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 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
