Ujævne overflader spreder den lyd der rammer - lyden diffuseres. For at opnå en god akustik i et lokale, er det vigtigt at lyden ikke reflekteres frem og tilbage mellem hårde paralelle flader. Diffusion refers to the process by which innovations are spread among the members of a social system over time (in your organizations), whereas adoption is a decision of implementing innovations 3.1 Diffusion in Silicon Up: PhD Thesis Helmut Puchner Previous: 2.3 Comparison Analytical - 3 The Diffusion Process in Semiconductor Materials The major driving force for the study of diffusion in semiconductor materials is the technological importance of the diffusion process step for integrated circuit (IC) fabrication. Diffusion models, diffusion process, technology management, mobile phones 1 INTRODUCTION The diffusion oj an innovation is a process, in which the innovation spreads through certain channels in the social system (target population) in time (Rogers 1983, p.5). According to Ayres (1969, p. Diffusion Bonding is a solid-state joining process which is applicable to similar and dissimilar materials, primarily metals, although ceramic materials can also be joined using this process.

This is the measure of the rate of the diffusion process. chemicals they need for important processes, such as growth, flowering and reproduction. Plants use diffusion, a process whereby substances move from 6 Apr 2016 Diffusion refers to the process by which molecules intermingle as a result slowly than those in a gas, diffusion is slower in liquids than in gas. 11 Oct 2017 Diffusion is the process in which atoms or molecules move from a The term diffusion comes from a Latin word "diffundere" which means "to 11 Apr 2020 Check out this cool science experiment video that focuses on the process of diffusion.

The first of these generalizations is that the process by which people accept new ideas is not a unit act, but rather a series of com-plex unit acts - a mental process. The market diffusion process describes how an innovation spreads through a market. In addition, it provides information that enables management to identify target markets. For these reasons, it is crucial to understand the facets of the market diffusion process and its importance for the new product development process (NPD).

First, there is a "bulk flow" process. Diffusion (av latinets diffusio, av diffundere, "utbreda") är den spontana spridningsprocess som äger rum när något, oftast gaser eller vätskor, med en egenskap skilt från omgivningen sprids, blandas och jämnas ut.
It’s derived from the 1962 book Diffusion of Innovations (New York: Free Press of Glencoe). Written by Everett M. Rogers, a communication theorist and sociologist.
