Lattice of weak hyper K-ideals of a hyper K-algebra

In this note, we study the lattice structure on the class of all weak hyper K-ideals of a hyper K-algebra. We first introduce the notion of (left,right) scalar in a hyper K-algebra which help us to characterize the weak hyper K-ideals generated by a subset. In the sequel, using the notion of a closure operator, we study the lattice of all weak hyper K-ideals of ahyper K-algebra, and we prove a ...

Handout 12 : Notes on Dynamic Programming 3 Item 1 2

However, there are only Bn problems that one needs to solve. Namely, it is enough to compute for every 1 ≤ k ≤ n and every 1 ≤ B′ ≤ B whether there is a subset S ⊆ {1, . . . , k} such that ∑ i∈S li = B ′. A dynamic programming algorithm computes a boolean matrix M [·, ·] having the property that M [k,B′] = True iff there is a subset S ⊆ {1, . . . , k} such that ∑i∈S li = B′. (We save some memor...

Fabrication and Characterization of Novel Mixed Matrix Polyethersulfone Based Nanofiltration Membrane Modified by Ilmenite (TECHNICAL NOTE)

This study is focused on fabrication and characterization of mixed matrix poly ether sulfone based nanofiltration membrane by phase inversion method. The effect of different amounts of Ilmenite (FeTiO3) particles as inorganic filler additive in the casting solution on physic-chemical characteristics of membranes was studied. Scanning electron microscopy, surface analysis, water content, contact...
