The new thiostannate Na4Sn2S6 was prepared by directed crystal water removal from the hydrate ⋅ 5H2O at moderate temperatures. While structure of comprises isolated [Sn2S6]4− anions, that anhydrate contains linear chains composed corner-sharing SnS4 tetrahedra, a structural motif not known in chemistry. This rearrangement requires bond-breakage anion, movements fragments opened anion and Sn−S−S...

This work presents (s, c)-Dense Code, a new method for compressing natural language texts. This technique is a generalization of a previous compression technique called End-Tagged Dense Code that obtains better compression ratio as well as a simpler and faster encoding than Tagged Huffman. At the same time, (s, c)-Dense Code is a prefix code that maintains the most interesting features of Tagge...

In this research study, the effects of aluminum nitride (AlN) additive on the densification behavior and microstructure development of titanium diboride (TiB2) based ceramic matrix composite were investigated. In this way, a monolithic TiB2 ceramic and a TiB2–5 wt% AlN ultrahigh temperature ceramic composite were fabricated by spark plasma sintering (SPS) proces...

Efficient Model Order Reduction of Electrical Networks with Many Ports Denis Oyaro Master of Applied Science Graduate Department of The Edward S. Rogers Sr. Department of Electrical and Computer Engineering University of Toronto 2015 Model order reduction of electrical networks plays a key role in accelerating circuit simulations. Traditional reduction methods, however, do not scale well with n...
