Hydropower Flexibility for Power Systems with Variable Renewable Energy Sources: An IEA Task 25 Collaboration
- 2019
-
Ingår i: Advances in Energy Systems. - : Wiley. ; , s. 385-405

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- In order to effectively utilize hydro production flexibility, a sufficient amount of transmission capacity has to be available between the hydro-dominated part of the system and the part that requires operational flexibility. This chapter starts with a rough categorization of “base” hydropower flexibility, investigating the types of hydropower plants installed in power systems today. The “effective” hydropower flexibility available to support the integration of variable generation is a far more complex and case-specific aspect. It is discussed through national experiences. The chapter presents potential developments that would increase the participation of hydropower and discuss the ensuing challenges. Modeling a flow-based hydro system is a complex exercise, as is modeling the power system. Especially important is the correct assessment of hydropower flexibility to support power systems with a large share of variable generation (VG) and its value for storage. With increasing uncertainty and variability, a stochastic scheduling approach should yield lower costs.

Cellulose nanofillers for food packaging
- 2011
-
Ingår i: Multifunctional and Nanoreinforced Polymers for Food Packaging. - Cambridge : Woodhead Publishing Limited. ; , s. 86-107
-
Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter presents a review of methods for the extraction of cellulose nanofillers, as well as the most important characteristic features related to the exploration of these nanofillers in composite applications. Various methods for the extraction and surface modification of cellulose crystals are presented for the adaption of cellulose crystals in composite applications. A brief review of the different morphological characteristics as well as mechanical properties of different cellulose nanofillers are also presented.

Bokkapitel (refereegranskat)abstract
- The marine environment harbors a large proportion of the total biodiversity on this planet, including the majority of the earths’ different phyla and classes. Studying the genomes of marine organisms can bring interesting insights into genome evolution. Today, almost all marine organismal groups are understudied with respect to their genomes. One potential reason is that extraction of high-quality DNA in sufficient amounts is challenging for many marine species. This is due to high polysaccharide content, polyphenols and other secondary metabolites that will inhibit downstream DNA library preparations. Consequently, protocols developed for vertebrates and plants do not always perform well for invertebrates and algae. In addition, many marine species have large population sizes and, as a consequence, highly variable genomes. Thus, to facilitate the sequence read assembly process during genome sequencing, it is desirable to obtain enough DNA from a single individual, which is a challenge in many species of invertebrates and algae. Here, we present DNA extraction protocols for seven marine species (four invertebrates, two algae, and a marine yeast), optimized to provide sufficient DNA quality and yield for de novo genome sequencing projects.

A Review of Hesitant Fuzzy Sets : Quantitative and Qualitative Extensions
- 2016
-
Ingår i: Fuzzy Logic in Its 50th Year. - Cham : Springer. - 9783319310930 - 9783319310916 ; , s. 109-128

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Since the concept of fuzzy set was introduced, different extensions and generalizations have been proposed to manage the uncertainty in different problems. This chapter is focused in a recent extension so-called hesitant fuzzy set. Many researchers have paid attention on it and have proposed different extensions both in quantitative and qualitative contexts. Several concepts, basic operations and its extensions are revised in this chapter.
