Database Perspectives on Blockchains [PDF]
Modern blockchain systems are a fresh look at the paradigm of distributed computing, applied under assumptions of large-scale public networks. They can be used to store and share information without a trusted central party. There has been much effort to develop blockchain systems for a myriad of uses, ranging from cryptocurrencies to identity control ...

This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Database Consistency Using Update-Ordering in Distributed Databases
Database consistency is one of the major issues in replicated database in distributed database systems. The logical design for the replicated nodes and the transaction management mechanism are two aspects that give a serious impact to the performance and

Modelling a transaction manager using parallel decision processes [PDF]
This is the second report concerning transaction management in the database environment. In the first report the role of the transaction manager in protecting the integrity of a database has been studied [van der Made-Potuijt 1989].

Probabilistic Frequent Pattern Growth for Itemset Mining in Uncertain Databases (Technical Report) [PDF]
Frequent itemset mining in uncertain transaction databases semantically and computationally differs from traditional techniques applied on standard (certain) transaction databases. Uncertain transaction databases consist of sets of existentially uncertain items. The uncertainty of items in transactions makes traditional techniques inapplicable. In this

A novel approach for alloy development in laser powder bed fusion is introduced. Instead of producing massive samples of one composition at a time, prepressed powder bed samples produced from powder mixtures are processed. Guidelines for the selection of precursor powders are developed.

Outlier Detection Credit Card Transactions Using Local Outlier Factor Algorithm (LOF)
Threats or fraud for credit card owners and banks as service providers have been harmed by the actions of perpetrators of credit card thieves. All transaction data are stored in the bank's database, but are limited in information and cannot be used as a ...

Transaction Management Model for Mobile Database [PDF]
Transaction support is crucial in mobile data management. Specific characteristics of mobile environments (e.g. variable bandwidth, disconnections, and limited resources on mobile hosts) make traditional transaction management techniques no longer ...
