This paper talks about the self-oraganized index maintainance approach of database cracking. It provides fundamental knowledge as well as the description of a basic implementation of database cracking. Alongside multiple cracking algorithms, the implementation also contains the code of a cracking index. By combining these two features the implementation allows the execution of range queries on ...
This work evaluated the process for heptaldehyde, undecylenic acid and methyl undecenoate production from castor oil, ester of oil ricinoleic acid. Experiments were performed in a continuous pilot-plant scale pyrolysis reactor. Those are very important green chemical products that might be obtained by thermal cracking oil. Transesterification produces ricinoleate its generates heptaldehyde. The...
background: solid targets that consist of powder and electrodeposited targets are used commonly to produce radionuclides by accelerators. since silver is easily electrodeposited in cyanide baths and has a very excellent thermal conductivity, the electrodeposited target is preferable to produce 109cd. to avoid cracking or peeling of the target during bombardment, it should have a level surface a...

With the rapid development of internet technologies, social networks, and other related areas, user authentication becomes more and more important to protect the data of the users. Password authentication is one of the widely used methods to achieve authentication for legal users and defense against intruders. There have been many password cracking methods developed during the past years, and p...
