Engine/Transmission Matching
2014
This chapter deals with the forecasting of vehicle performance on the road, according to the installed engine. It begins with Section 1, which shows the calculation of the resistance to motion, that is, the forces that the vehicle must overcome to advance on flat roads and uphill. The calculation excludes accidental resistance in curves because it is not essential for predicting the behavior of the vehicle on the road. Section 2 begins with the power characteristic, the forecast by traction–speed and power–speed diagrams, calculation of gear ratios, and then passing to the limits to the estimated acceleration, feature consumption, and distance. This chapter concludes with a section on the d…
Does using a visual-representation tool foster students’ ability to identify forces and construct free-body diagrams?
2013
Earlier research has shown that after physics instruction, many students have difficulties with the force concept, and with constructing free-body diagrams (FBDs). It has been suggested that treating forces as interactions could help students to identify forces as well as to construct the correct FBDs. While there is evidence that identifying interactions helps students in quantitative problem solving, there is no previous research investigating the effect of a visual-representation tool—an interaction diagram (ID)—on students’ ability to identify forces, and to construct the correct FBDs.We present an empirical study conducted in 11 Finnish high schools on students (n ¼ 335, aged 16) takin…

Augšdevona ūdens horizontu apūdeņotību raksturojošie parametri un to savstarpējā saistība Latvijas teritorijā
2017
Maģistra darba “Augšdevona ūdens horizontu apūdeņojošie parametri un to saistība Latvijas teritorijā” galvenais mērķis ir, izmantojot pieejamos urbumu datus, atrast sakarības starp augšdevona ūdens horizontu apūdeņotību raksturojošiem parametriem – caurplūdes koeficientu T un īpatnējo debitu q. Izpildot izvirzītos uzdevumus secināts, ka pastāv sakarības starp ūdens horizontu apūdeņotību raksturojošām q un T vērtībām, bet šīs sakarības ticamību būtiski ietekmē ūdens horizontu veidojošie nogulumi, galvenokārt, to viendabīgums. Nav konstatēts kāds izteikts parametrs ar ļoti būtisku ietekmi - vairāku faktoru mijiedarbība raksturo apūdeņotību Latvijā.
