Preprocessing Of Astronomical Images From The Neowise Survey For Near-Earth Asteroid Detection, Rachel Meyer Apr 2022

Preprocessing Of Astronomical Images From The Neowise Survey For Near-Earth Asteroid Detection, Rachel Meyer

Scholar Week 2016 - present

Asteroid detection is a common field in astronomy for planetary defense which requires observations from survey telescopes to detect and classify different objects. The amount of data collected each night is increasing as better designed telescopes are created each year. This amount is quickly becoming unmanageable and many researchers are looking for ways to better process this data. The dominant solution is to implement computer algorithms to automatically detect these sources and to use Machine Learning in order to create a more efficient and accurate classifier. In the past there has been a focus on larger asteroids that create streaks …

Performance Analysis Of Java Persistence Api Providers, Besart Pllana Oct 2018

Performance Analysis Of Java Persistence Api Providers, Besart Pllana

UBT International Conference

Nowadays, fast and accurate access to data is very important. Usually data is managed and processed through software applications. In recent years, the most preferred programming model by most application developers is Object Oriented Programming (OOP) where data is represented through objects. These data must be persistent and therefore needs to be stored, and storage can be done on a variety of databases. The most common databases are Relational Database Management Systems (RDBMS). While persistence of objects in RDBMS is limited by object-relational mismatch which is the inconsistency of the direct interaction between two components based on different approaches, OOP …

Sort Vs. Hash Join On Knights Landing Architecture, Victor L. Pan, Felix Lin Aug 2018

Sort Vs. Hash Join On Knights Landing Architecture, Victor L. Pan, Felix Lin

The Summer Undergraduate Research Fellowship (SURF) Symposium

With the increasing amount of information stored, there is a need for efficient database algorithms. One of the most important database operations is “join”. This involves combining columns from two tables and grouping common values in the same row in order to minimize redundant data. The two main algorithms used are hash join and sort merge join. Hash join builds a hash table to allow for faster searching. Sort merge join first sorts the two tables to make it more efficient when comparing values. There has been a lot of debate over which approach is superior. At first, hash join …

Modelling Approach For A Pcb Inventory In Our Environment, Gerlinde Knetsch Jul 2016

Modelling Approach For A Pcb Inventory In Our Environment, Gerlinde Knetsch

International Congress on Environmental Modelling and Software

The data of more than 100 monitoring programs in Germany for the substance group of persistent organic pollutants (POPs), including the polychlorinated biphenyls (PCBs) are to be used for a modelling approach for a PCB inventory. The application landscape of the Federation/Laender POP-DioxinDatabase, which is operated in the German Environment Agency, pursues an interdisciplinary approach and includes all these data. A cross-media evaluation and assessment of environmental data are necessary and relevant to the target system, compiling an inventory of PCBs in our environment. The question arises how the integrated modelling concept can control the knowledge-based methods, with the aim …

Database For Online Accreditation Process In Directorate For Accreditation Of Kosovo (Dak-Mis), Ibush Luzha

UBT International Conference

Directorate for Accreditation of Kosovo (DAK) is only National Accreditation Body in Republic of Kosovo, recognized by Government, which in accordance with international standards, assesses technical competences of the Conformity Assessment Bodies (CAB)s that deal with activities such as: testing, calibration, certification and inspection both in public and private sector. Till now application for accreditation and all other procedures for accreditation of CABs are carried out so that all the documents of the application and the receipt of the certificate of accreditation are conducted in the offices of DAK. By Management Information System (MIS), database of DAK (DAK-MIS), customers will …

An Integrative Modeling Framework To Evaluate Wheat Production Systems: Fusarium Head Blight, Willingthon Pavan, José Maurício Cunha Fernandes, Alexandre Lazzaretti, Josué Toebe, Jorge Luis Bavaresco, Alex C. Ruane, Rodrigo Yoiti Tsukahara Jun 2014

An Integrative Modeling Framework To Evaluate Wheat Production Systems: Fusarium Head Blight, Willingthon Pavan, José Maurício Cunha Fernandes, Alexandre Lazzaretti, Josué Toebe, Jorge Luis Bavaresco, Alex C. Ruane, Rodrigo Yoiti Tsukahara

International Congress on Environmental Modelling and Software

This paper describes a practical, integrated, web-based and user friendly analysis tool for crop model users that provides quality control of input data, tracks user selections in model parameterization, and enables visual analysis of model outcomes using a single graphical user interface. This allows the user to undertake numerous steps in crop modeling and analysis in a seamless and integrated environment. The analysis and visualization components of the system were enabled utilizing R (pl/r) and the robustness of the underlying data structures and coupling point between crop and disease models were achieved through use of PostgreSQL database management system. The …
