Opis:
The paper presents a static model of the price calculation for the various alternative electricity sources, and includes technical and economic performance of different energy sources for the guaranteed power. The table with calculated technical and economic indicators for various alternative energy sources is provided. The presented dynamic model which unites energy indicators of power generating systems and economic indicators of the closed macroeconomic system because price regulation on the power market of Ukraine happens in a statics. That’s why not allowed to perform an assessment of dynamic change of the tariff price of the electric power in the local isolated systems. When abrupt change isolated power generating capacity of the system is changing the tariff price of electricity cannot be taken into account when using static models. An example of the isolated system consisting of the diesel generator and the consumer is reviewed. The model allows to research influence of transition processes of the generator on change of cost indicators of an economic system, and also to estimate the adequate tariff price both for the producer, and for consumers of the electric power. This model is modelled in Matlab.

Opis:
Purpose: The purpose of the current study was to investigate whether an isolated human body lower limb FE model could predict leg kinematics and biomechanical response of a full body Chinese pedestrian model in vehicle collisions. Methods: A human body lower limb FE model representing midsize Chinese adult male anthropometry was employed with different upper body weight attachments being evaluated by comparing the predictions to those of a full body pedestrian model in vehicle-to-pedestrian collisions considering different front-end shapes. Results: The results indicate that upper body mass has a significant influence on pedestrian lower limb injury risk, the effect varies from vehicle front-end shape and is more remarkable to the femur and knee ligaments than to the tibia. In particular, the upper body mass can generally increase femur and knee ligaments injury risk, but has no obvious effect on the injury risk of tibia. The results also show that a higher attached buttock mass is needed for isolated pedestrian lower limb model for impacts with vehicles of higher bonnet leading edge. Conclusions: The findings of this study may suggest that it is necessary to consider vehicle shape variation in assessment of vehicle pedestrian protection performance and leg-form impactors with adaptive upper body mass should be used for vehicles with different front-end shapes, and the use of regional leg-form impactor modeling the local anthropometry to evaluate the actual lower limb injury of pedestrians in different countries and regions.
