Such a cultural change requires that requirements are defined and managed systematically, not only from a technical point of view, but also from the customers’ and users’ points of view. This paper describes experiences gained from four Finnish organizations that have started to introduce requirements en...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Background. Considering that a person's physical and psychological possibilities are not limitless, the technical means used by athletes are of great importance. In order to achieve high results in the kayak sprint competition, users-athletes orient to the highest quality products; therefore, a significant task falls to their manufacturers to analyze the competitors' products, evaluate users' n...
Developing a usable product involves more than considering the user interface. The product should also fit into a context of use and meet user requirements. It remains a challenge to represent use contexts and user needs in a way that designers with technical backgrounds are able to make direct use of them. This paper proposes an approach to representing user needs and translating them into use...

network expansion studies normally offer new power lines, new substations or expansion of existing substations. they are generally proposed based on technical requirements, but financial restrictions are not considered. because of financial restrictions, ranking of network expansion plans is required. in this paper an algorithm for such ranking, based on technical and financial view points and ...
In this study, water management allocated to the agricultural sector’ was analyzed using stochastic dynamic programming under uncertainty conditions. The technical coefficients used in the study referred to the agricultural years, 2013-2014. They were obtained through the use of simple random sampling of 250 farmers in the region for crops wheat, barley, melon, watermelon and ruby grapes under ...
