Abstract: A method of forming an air gap or gaps within solid structures and specifically semiconductor structures to reduce capacitive coupling between electrical elements such as metal lines, wherein a norbornene-type polymer is used as a sacrificial material to occupy a closed interior volume in a semiconductor structure. The sacrificial material is caused to decompose into one or more gaseous decomposition products which are removed, preferably by diffusion, through an overcoat layer. The decomposition of the sacrificial material leaves an air gap or gaps at the closed interior volume previously occupied by the norbornene-type polymer. The air gaps may be disposed between electrical leads to minimize capacitive coupling therebetween.

Abstract: A process for treating fly ash to render it highly usable as a concrete additive. A quantity of fly ash is obtained that contains carbon and which is considered unusable fly ash for concrete based upon foam index testing. The fly ash is mixed with an activator solution sufficient to initiate a geopolymerization reaction and for a geopolymerized fly ash. The geopolymerized fly ash is granulated. The geopolymerized fly ash is considered usable fly ash for concrete according to foam index testing. The geopolymerized fly ash may have a foam index less than 35% of the foam index of the untreated fly ash, and in some cases less than 10% of the foam index of the untreated fly ash. The activator solution may contain an alkali metal hydroxide, carbonate, silicate, aluminate, or mixtures thereof.

Abstract: The invention relates to a method for preventing TCP SYN package flood attack, and belongs to the computer network security field. First, the firewall receives a client a TCP SYN connection request package, and responses, as an agent of the server, an acknowledgement of the TCP SYN connection request package with zero window size to the client. Then, the firewall records information about the TCP SYN connection request package and checks whether the connection request is legal. When the firewall has received a TCP SYN response package from the server, it returns an acknowledgement of said TCP SYN response package. At the same time, the firewall, as an agent of the server, sends an acknowledgement packet with nonzero window size to the client for initiating data transmission from the client. After that, data packets are transferred between the client and the server forwarded by the firewall as an agent.
