Taisnes nogriežņu telpiskas tīklveida konfigurācijas algoritmiska atpazīšana no stereopāra
2017
Mācību rakstura mēģinājums telpiski atpazīt specifiskus stereopārus, kurus veido telpisku ģeometrisku grafu divas plakanas projekcijas. Aplūkoto ģeometrisko grafu šķautnes ir taisnes nogriežņi, bet virsotnes šo nogriežņu galapunkti. Ar šādiem grafiem, kurus saucam arī par nogriežņu tīkliem, mēs vienkāršoti un abstrakti modelējam gan dabisku, gan mākslīgu telpiskus tīklus veidojošu līniju struktūru fundamentālo uzbūvi. Piemēram, organisma asinsvadu tīklus vai augu lapu dzīslojumus bioloģijā, vai dažādas stieņu konstrukcijas sadzīvē un industrijā. Šādā nostādnē algoritmiskajā apstrādē dominē struktūru kombinatoriskais aspekts, kuru tad arī mēs izvēršam savā darbā. Mūsu mērķis bija pārliecināt…
Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans
2017
In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…
Effects of integrating a bioethanol production process to a kraft pulp mill
2010
Abstract The integration of an ethanol production process based on prehydrolysis of softwood chips to a kraft pulp mill is discussed. A simulation model of this biorefinery has been created with WinGEMS simulation software to calculate the mass and energy balances of the biorefinery and to examine the effects of the integration on the operation of the pulp mill. Integrating the prehydrolysis process to the modeled pulp mill producing 1000 Adt/day of pine pulp would increase the wood consumption by 16%. With the increased wood consumption, 40 t/day of ethanol could be produced, and the excess power production could be increased by 460 MWh/day. The integration of the ethanol production proces…
Effect of indirect composite treatment microtensile bond strength of self-adhesive resin cements
2016
Background: No specific indications about the pre-treatment of indirect composite restorations is provided by the manufacturers of most self-adhesive resin cements. The potential effect of silane treatment to the bond strength of the complete tooth/indirect restoration complex is not available.The aim of this study was to determine the contribution of different surface treatments on microtensile bond strength of composite overlays to dentin using several self-adhesive resin cements and a total-etch one. Material and Methods: Composite overlays were fabricated and bonding surfaces were airborne-particle abraded and randomly assigned to two different surface treatments: no treatment or silane…
