The objective of the dissertation thesis was to evaluate the effects of two different types of milking systems (CMS - conventional milking system vs. AMS - an automatic milking system) on average daily milk yield, on frequency of attending robots, on pre-milking teat preparation procedures and stimulation and milking time, on the teats traumatization of Holstein cows. The experiments were performed in two locations: Žabčice School Farm of Mendel University in Brno and ZEMAX, a. s. in Šitbořice. Data was collected for a period 1st January 2014 to 15th December 2015. Higher average milk yield per day and lower milk yield per milking on the other hand on the farm with AMS were caused by a higher frequency of milking. Cows on farm with CMS were milked twice a day. On the farm with AMS dairy cows were milked in accordance with their own needs. Milking frequency in the AMS was in 2014 2.47, in 2015 2.88 per day. Heat stress has negative impacts on milk production. Effect of heat stress showed more markedly in 2015, which is probably related to the fact that the value of THI greater than 80 lasted longer. The length of pre-milking teat preparation procedures and stimulation various neighborhoods was found in AMS in 2014 from 0:13 min. to 0:16 min., in 2015 from 0:14 min. to 0:19 min. On farm with CMS time not be registered. The length of milking time with CMS in both years was 5:02 min. In AMS was in 2014 from 3:03 minutes to 3:53 min., in 2015 from 3:05 min. to 4:45 minutes. In process of milking machine teat traumatization were smaller when using AMS.

The purpose of my project has been to create a voting feature on a campaign site for WWF, where visitors to the website can participate in voting and vote for different cities around the world to improve their sustainability efforts. The website has been developed in WordPress based on specified requirements, including security and voting frequency. The development of the website and the plugin has been done in collaboration with other developers in the project. For the website, a custom WordPress theme was created, and the majority of the site was constructed using custom Gutenberg blocks. A survey was performed to compare and analyze existing plugins in WordPress, and an evaluation showed that a custom-developed plugin for the project was the most suitable option. To achieve maximum security on the website, existing security features in WordPress were used, and control of the voting frequency were implemented. The result of the project culminated in a voting feature on the website, where votes were controlled, and the administration interface required authorized users. User tests of the website with colleagues on the company were planned, but due to time constraints, they could not be carried out before the project deadline. These tests were primarily intended to verify the functionality of the voting feature. / Syftet med mitt projekt har varit att skapa en röstningsfunktion på en kampanjsite för WWF där besökare på webbplatsen ska kunna delta i omröstning och rösta på olika städer världen över för att förbättra städernas hållbarhetsarbete. Webbplatsen har utvecklats i WordPress utifrån uppsatta krav på bland annat säkerhet och röstningsfrekvens. Utvecklingen av webbplatsen och pluginet har skapats i samarbete med övriga utvecklare i projektet. För webbplatsen skapades ett eget WordPress tema och med egenutvecklade Gutenberg-block konstruerades merparten av siten. En undersökning har utförts för att jämföra och analysera befintliga plugins i WordPress och en utvärdering visade att ett egetutvecklat plugin för projektet var det mest passande alternativet. För att uppnå maximal säkerhet på webbplatsen användes befintliga säkerhetsfunktioner i WordPress och bland annat röstningsfrekvensen kontrollerades. Resultatet av projektet utmynnade i en röstningsfunktion på webbplatsen där röstningar kontrollerades och administrationsgränssnittet krävde auktoriserad användare. Användartester av webbplatsen med testpersoner inom företaget planerades, men på grund av tidsbrist hann dessa inte genomföras innan projekttiden löpte ut. Dessa var tänkta främst till att kontrollera röstningsfunktionens funktionalitet.

The following report discusses the use of the Blackboard Course Management in terms of overall patterns of activity as recorded in the Blackboard activity database across the whole campus of Brigham Young University during the 2004-2005 academic year. The report contains a set of data represented by tables and graphs that summarize activity, or clicks, in the Blackboard system performed by students, professors, and assistants. The clicks are summarized according to a number of different categories and criteria and analyzed to show interesting patterns of activity. The report is designed to show a general campus wide summary of Blackboard activity and also to briefly explore patterns that may be used as a platform for further detailed research.

Although astrophysical evidence supports the existence of dark matter (DM), it remains one of the unanswered questions left by the Standard Model (SM) of Particle Physics. However, under hypotheses of new interactions, the production of dark matter can be detected as an excess of events with large missing transverse momentum (p_T^miss) over the SM background process. This thesis documents a search for new particles at the Compact Muon Solenoid (CMS) at the Large Hadron Collider (LHC), targeting events where large p_T^miss and energetic jets are produced in a proton-proton collision at 13 TeV. The data were collected from 2017 to 2018 during the second half of LHC Run-II. The analysis also targets events where a jet is produced from W or Z bosons identified by a deep-neural-network-based tagger. Multiple control regions targeting specific background processes are defined which estimate background yield in the signal region through a simultaneous fit across control regions of all search channels. The result for the Run-II data corresponding to an integrated luminosity of 137 fb^-1 is obtained by combining this analysis with the previously published 2016 data. No excess of events is observed compared to the SM background expectations. The result of this search is interpreted in several new physics models, including simplified dark matter models, large extra dimension model (ADD), Higgs portal models, and leptoquark models. Limits are set on model parameters providing the most stringent direct constraints on dark matter search from colliders.

<p>Syftet med detta arbete är att utvärdera innehållshanteringssystemet WordPress och sättet man utvecklar ytterligare funktionalitet för detta system. Arbetet berör utformning av administreringsverktyg för godkännande av inlägg samt ett verktyg för att hantera de företag som ska kunna länkas in under olika sidor på en portal vid namn ImageTalk. ImageTalk är slutprodukten, och är en webbplats för publicering av digital media på internet.</p><p>WordPress är skrivet i PHP och använder sig av css, javascript och databasen mySQL. Eftersom detta innehållshanteringssystem är vida använt kändes det både relevant och intressant att utvärdera, särskilt genom att tillföra ny funktionalitet.</p><p>Slutsatsen av detta arbete är att WordPress är ett mycket kompetent innehållshanteringssystem som har mycket goda förutsättningar för att byggas ut och förändras på de flesta sätt. Däremot är det svårt att ge en ordentlig struktur i den ytterligare funktionalitet man tillför, eftersom den ibland blir för utspridd eller ibland inte tillräckligt skingrad.</p> / <p>The purpose of this work is to evaluate the content management system WordPress and the way to develop additional functionality for this system.

Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro / Apresenta-se neste trabalho um estudo sobre o impacto do empilhamento de eventos (pile-up), nas distribuições das variáveis comumente utilizadas para identificar eventos difrativos, na topologia de difração dura simples produzindo dijatos, nas condições do CMS para baixa luminosidade (2 x 1033 cm -2 s-1). O cenário de baixa luminosidade citado acima equivale aproximadamente a 5 eventos de pile-up em média por cruzamento de pacotes. Para simular o sinal, difrativos (com e sem pile-up), usamos o gerador POMWIG (1). Para os eventos não-difrativos (com e sem pile-up), utilizamos o gerador PYTHIA (2),bem como para a produção dos eventos de pile-up (eventos simulados utilizando eventos de minimum bias). / We present here a study on the pile-up impact in the variables commonly used to identify diffractive events, the topology of single diffraction producing hard jets in the CMS conditions for low luminosity (2 X 1033 cm -2 s-1). The low luminosity scenario mentioned above is equivalent to approximately 5 pile-up events on average by crossing packages. To simulate the signal, diffractive events (with and without pile-up), we use the generator POMWIG(1). For the non-diffractive events (with and without pile-up), we use generator PYTHIA(2), and for the production of events of pile-up as well (events simulated using minimum bias events).

Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro / Este trabalho apresenta um estudo sobre a produção de dijatos exclusivos em interações pp, do tipo pp &#8594; p "+" dijatos "+" p, onde os prótons desta interação permanecem intactos, e o símbolo "+" indica uma lacuna na pseudorapidez, uma região com ausência de atividade hadrônica entre os prótons espalhados e o sistema central de dijatos; este processo é conhecido como produção central exclusiva. A análise utiliza uma amostra de dados que corresponde a uma luminosidade efetiva de 24;48 pb-1 coletados pelo experimento Compact Muon Solenoid (CMS) no Large Hadron Collider (LHC), no ano de 2010, com energia de centro de massa &#8730;s = 7 TeV. Este canal possui uma assinatura experimental única, caracterizada pelos prótons espalhados na região frontal, ou a baixos ângulos e duas grandes lacunas opostas. O processo da produção central exclusiva é útil para o entendimento das interações no contexto da QCD. / This work presents a study about the exclusive dijets production in pp interactions of type pp &#8594; p "+" dijets "+" p, where the protons this interaction remain intact, and the symbol "+" denotes a gap in pseudorapidity, a region with no hadronic activity between the scattered protons and the central dijets system, this process is known as central exclusive production. The analysis uses a data sample corresponding to effective luminosity of 24:48 pb -1 collected by the experiment Compact Muon Solenoid (CMS) at Large Hadron Collider (LHC), in 2010, with center of mass energy of &#8730;s = 7 TeV. This channel has a experimental signature unique, characterized by scattered protons in the frontal region or low angles and two large gaps opposite. The central exclusive production process is useful for understanding the interactions in the context of QCD.
