Methods for Comparing Database Management SystemsTörnqvist, Jakob January 2023 (has links)
Zenon AB is an it-company of which, this thesis was made in collaboration with. Zenon AB has clients that generate large amounts of data, therefore it is important for Zenon AB that they make competent choices of database management systems (DBMS) when designing systems for their clients. This thesis will therefore entail research carried out into the comparison of DBMS. Nowadays, there exists a large variety of DBMS. Despite this, there seems to be a lack of comparisons between types of DBMS and therefore a lack clarity of when each type should be used. Thus, this thesis aims to highlight these differences of DBMS types by creating a tailored test for each DBMS type and compare how each type performs in each-others area of specialization. This process will show how big the differences can be and highlight the importance of the choice of DBMS. The time it takes, and how simple DBMSs are to implement seems to be a factor most developers take into consideration when choosing DBMS but there is little research on how to compare the aspect. Therefore, this thesis will investigate the viability of a method to compare how easy the DBMSs are to implement into systems by querying programming help forums such as Stackoverflow. / <p>Examensarbetet är utfört vid Institutionen för teknik och naturvetenskap (ITN) vid Tekniska fakulteten, Linköpings universitet</p>

An Application of Multidisciplinary Water Resources Planning and Management for the San Carlos Apache Indian Reservation: Gila River CaseNovelle, M. E., Percious, D. J., Wright, N. G. 16 April 1977 (has links)
From the Proceedings of the 1977 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona Academy of Science - April 15-16, 1977, Las Vegas, Nevada / The Laboratory of Native Development, Systems Analysis and Applied Technology (NADSAT) was established to provide technical assistance to southwestern Indian Tribes as an aid in the development and use of their natural resources according to their goals and objectives. NADSAT 's role is assistance and technology transfer, with an emphasis on alternative formulation and performance analysis and communicating the technological approach to tribal decision makers. The cost-effectiveness methodology provides a coherent framework and affords a mechanism for technology transfer, which makes it a useful tool in achieving tribal goals. This method was applied to the formulation of possible alternatives for use of the land and water resources of the Gila River Basin within the San Carlos Apache Indian Reservation. Criteria for devising various alternative utilization schemes are discussed, and the advantages of the cost effectiveness methodology.

Fast Low Memory T-Transform: string complexity in linear time and space with applications to Android app store security.Rebenich, Niko 27 April 2012 (has links)
This thesis presents flott, the Fast Low Memory T-Transform, the currently fastest and most memory efficient linear time and space algorithm available to compute the string complexity measure T-complexity. The flott algorithm uses 64.3% less memory and in our experiments runs asymptotically 20% faster than its predecessor. A full C-implementation is provided and published under the Apache Licence 2.0. From the flott algorithm two deterministic information measures are derived and applied to Android app store security. The derived measures are the normalized T-complexity distance and the instantaneous T-complexity rate which are used to detect, locate, and visualize unusual information changes in Android applications. The information measures introduced present a novel, scalable approach to assist with the detection of malware in app stores. / Graduate

Anonymní pohyb v síti internet / Anonymous communication on the internetHořejš, Jan January 2014 (has links)
The objective of this master’s thesis was to describe current capabilities of anonymous browsing over the Internet. The theoretical part focuses on three main methods of anonymization with main focus on Tor network. The master‘s thesis describes advantages and disadvantages of different solutions and possible attacks on them. In the next part is demonstrated Tor network, implementation of Hidden service and secured access to the server for clients and possible attacks against this proposal. The work also includes the results of measurements of all three anonymizers and the effects on their speed.

Inteligentní emailová schránka / Intelligent MailboxPohlídal, Antonín January 2012 (has links)
This master's thesis deals with the use of text classification for sorting of incoming emails. First, there is described the Knowledge Discovery in Databases and there is also analyzed in detail the text classification with selected methods. Further, this thesis describes the email communication and SMTP, POP3 and IMAP protocols. The next part contains design of the system that classifies incoming emails and there are also described realated technologie ie Apache James Server, PostgreSQL and RapidMiner. Further, there is described the implementation of all necessary components. The last part contains an experiments with email server using Enron Dataset.

Stratigraphy and Sedimentology of the Bisbee Group in the Whetstone Mountains, Pima and Cochise Counties, Southeastern ArizonaArchibald, Lawrence Eben January 1982 (has links)
The Aptian-Santonian(?) Bisbee Group in the Whetstone Mountains comprises 2375 m of clastic sedimentary rocks and limestones. The basal Glance Conglomerate unconformably overlies the Pennsylvanian-Permian Naco Group. It consists of limestone conglomerates which were deposited in proximal alluvial fan environments. The superadjacent Willow Canyon Formation contains finer grained rocks which were deposited in the distal portions of alluvial fans. The lacustrine limestones in the Apache Canyon Formation interfinger with and overlie these alluvial fan facies. The overlying Shellenberger Canyon Formation is composed mostly of terrigenous rocks derived from westerly terranes. This formation contains thick sequences of fluvio-deltaic facies as well as a thin interval of estuarine deposits which mark a northwestern extension of the marine transgression in the Bisbee -Chihuahua Embayment. The youngest formation (Upper Cretaceous?) in the Bisbee Group, the Turney Ranch Formation, consists of interbedded sandstones and marls which were deposited by fluvial and marine(?) processes.
