Abstract

Cytochrome P450 enzymes are hemoproteins showing extraordinary di- versity in the reactions they catalyze. We developed a database containing all the needed data to provide a comprehensive data source on reactions cat- alyzed by cytochrome P450 enzymes. This data mainly includes information about the substrates, products of characterized reactions, and the sequence of these enzymes. The database was developed by collecting data from reliable protein and reaction databases like UniProt and RHEA. The work presents an in-depth analysis of the created database of reactions catalyzed by cy- tochrome P450 enzymes. This database can be utilized for future machine learning approaches to predict the function of uncharacterized cytochrome P450s.

Abstract

This paper describes possibilities of using replications for updating database applications. This approach is based on the fact that each database application can be divided into three main parts: presentation functions, application functions and data management. Application functions represent logic of the application (data processing in the database application) and they can be implemented by means of DataBase Management Systems (DBMS), i.e. stored procedures, triggers, user defined functions and rules. Next the paper characterizes the replications and describes their categorization and properties. Considering that the replications in distributed DBMS allow to send to the remote node not only tables with data, but also selected stored procedures, triggers, user defined functions and rules, the update of the entire database application can be executed using replications. In the conclusion the paper compares the update of a database application using SQL scripts and replications. [ABSTRACT FROM AUTHOR]

Abstract

4th International Symposium on Multidisciplinary Studies and Innovative Technologies, ISMSIT 2020 -- 22 October 2020 through 24 October 2020 -- -- 165025 Queueing theory deals with creating mathematical models for waiting and queueing events. These determine the performance values of waiting lines, such as queue length, occupancy rate, waiting time, arrival, and service rates. Estimation or detection of these issues provide benefits for problems, such as, the design of road structures, length of turn lanes, number of lanes at intersections, number of box offices and traffic signal timing. Queueing models are created with some determinations or assumptions, such as arrival patterns, departure characteristics and service discipline of the vehicles coming to the system. In this study, firstly a queuing model was created with some assumptions, then the arrival and departure distributions of the data were examined, and a new queue model was determined based on the results. According to the distribution of the data collected from signalized intersection, the model was renewed, and the performance of the queuing was obtained. The results according to M/M/1, M/G/1 and G/G/1 models are compared. © 2020 IEEE.
