Wind Farm Optimization

Sogand, Yousefbeigi 01 March 2013 (has links) (PDF)
In this thesis, a mixed integer linear program is used to formulate the optimization process of a wind farm. As a start point, a grid was superimposed into the wind farm, in which grid points represent possible wind turbine locations. During the optimization process, proximity and wind interference between wind turbines were considered in order to found the power loss of the wind farm. Power loss was analyzed by using wind interference coefficient, which is a function of wind intensity interference factor (WIIF), weibull distribution and power of the wind turbines. Two different programs / Genetic Algorithm and Lingo, were used to solve the MILP optimization formula and results were compared for different cases in the conclusion part.

Regulation of the Proteolytic Processing and Function of Amyloid Precursor Protein by Candidate Ligands

Rice, Heather Caroline 28 August 2013 (has links)
Despite intense interest in the proteolysis of Amyloid Precursor Protein (APP) in Alzheimer’s disease (AD), how the normal processing and function of this type I receptor-like glycoprotein is regulated remains ill-defined. APP is reported to function in neurodevelopment, including migration of neuronal precursor cells into the cortical plate. In recent years, several candidate ligands for APP, including F-spondin, Reelin, \(\beta1\) Integrin, Contactins, and Lingo-1 have been reported. However, a cognate ligand for APP that regulates its function or processing has yet to be widely confirmed in multiple laboratories. First, in an unbiased approach to reveal novel ligands, Pancortin was identified by a mass spectrometry-based screen for factors that bind to the APP ectodomain in rodent brain. Each of the Pancortin isoforms was confirmed to interact with APP. However, only specific Pancortin isoforms reduced \(\beta\)-secretase but not \(\alpha\)-secretase cleavage of endogenous APP. Using in utero electroporation to overexpress or knockdown Pancortin isoforms in rodent cortex, a previously unidentified role for Pancortin in cortical cell migration with evidence for a functional interaction with APP was discovered. Next, I developed new assays in an effort to confirm a role for one or more of the published candidate ligands in regulating APP ectodomain shedding in a biologically relevant context. A comprehensive quantification of APPs\(\alpha\) and APPs\(\beta\), the immediate products of secretase processing, in both non-neuronal cell lines and primary neuronal cultures expressing endogenous APP yielded no evidence that any of these published candidate ligands stimulate ectodomain shedding. Rather, Reelin, Lingo-1 and Pancortin emerged as the most consistent ligands for significantly inhibiting ectodomain shedding. These studies clarify mechanisms regulating the function and processing of APP, which is needed to understand consequences of chronically altering APP proteolysis to treat AD and to develop new potential drug targets.

Optimization combined with process mapping for maximizing product utilization : Investigating the utilization of products in sawmills, a case study

Höglund, Jonas January 2018 (has links)
The handling and utilization of products is an important factor in organization that strive towards and optimal operation, where different methods in the handling of products have a direct effect on the organizations results. This is a case study where a sawmill with a process that is repeated for each new order in the sorting- and packaging of timber. For each scenario, an operator is faced with a decision, where the result of the organization is directly affected by the decision that is made. The decision in question consist of an amount of trays of timber that must be combined in order to meet a constraint in the height of each delivered package. The purpose with this study is to investigate how optimization combined with process mapping can help the organization in maximizing its utilization of products. The study was performed with a mixed methods approach, where a process map was developed to gain understanding of the process. An optimization model was developed and run given collected data. In the process mapping it became clear that for each combination of trays, there is a downgrading in length and/or quality, which affects the total value of the combination. A comparison of the results between the optimization models’ and operators’ solutions showed a theoretical saving of 3 655 435 kr annually, and an increase in product utilization of 3,81 percentage in this process. The results of the study shows that optimization combined with process mapping is effective in the terms of minimizing costs dependent on a decision maker.

Jonasson, Per, Elmvik, Ola January 2002 (has links)
Interaktiv 3d-grafik är ett område som i dagsläget genomgår stora förändringar med ständigt ökad efterfrågan. Tack vare förbättrad mjuk- och hårdvara går det idag att åstadkomma saker som bara för ett par år sedan var fiktion. Syftet med rapporten är att dokumentera dessa möjligheter genom att undersöka grunderna för hantering och manipulering av 3d-modeller i programvaran Macromedia Director 8.5, samt implementera denna kunskap i en interaktiv 3d- applikation. 3d-grafik som används i Director är polygonbaserad och renderas i realtid på användarens dator. Moduleringen av 3d-grafiken kan utföras på två sätt, antingen i programmeringsspråket Lingo eller via fristående program. Director erbjuder goda möjligheter för manipulering av 3d-modeller vilket har utnyttjas i arbetets praktiska del. Den praktiska delen av vårt arbete har resulterat i en applikation där användaren kan inreda ett virtuellt rum i 3d-miljö. All interaktion med denna sker i realtid. Applikationen kan användas som plattform för projekt där företag vill visualisera sina produkter i en interaktiv 3d-miljö. För att skapa en sådan interaktiv 3d-miljö krävs det i dagsläget goda kunskaper om hur 3d-grafik är uppbyggd och hur den hanteras i programmeringsspråket Lingo. Denna rapport är ämnad att ge läsaren en inblick av detta.

Managementspråket idag : En analys av fyra managementkonsultbolags språkbruk på webben / Management lingo today : a study of four management consulting companies’ parlance on their websites

Lindén, Pernilla January 2018 (has links)
Syftet med denna studie var att undersöka hur språkanvändningen på en särskild kommunikationskanal, nämligen webbsidor, ser ut hos olika företag inom branschen för managementkonsulting. Studien gjordes på uppdrag av Madicon Communication AB vilket är grunden till att ett vidare syfte även var att undersöka hur Madicon med hjälp av språket och de likheter samt skillnader som framkommit kan positionera sig annorlunda i förhållande till andra företag i samma bransch. I denna undersökning studerades komposition samt frekvens av engelska uttryck, facktermer, upprepningar, pronomen och tilltal, informella och formella ordval och användning av versaler samt språkhandlingar. Resultatet visade bland annat att alla fyra företagen till stor del använder samma delar i kompositionen, men att det finns skillnader beroende på företagens inriktningar. Vidare använder de två tekniskt inriktade företagen engelska mest. Facktermer visade sig tydligt ha en väsentlig roll inom managementspråket då stor mängd påträffats i texterna. När det kommer till upprepningar och hur företagen valde att synas i sina texter kunde vi återigen se skillnad utefter företagens inriktning. Utifrån studiens resultat är endast Madicon det företag som följer riktlinjerna om att företag vinner på att låta både ett ’vi’ och ett ’du’ synas i texter på webben. Resultatet visade även att företagen håller olika grad av formalitet vilket möjligt gör att företagen uppfattas olika. Madicon använder i jämförelse med de andra företagen versaler mer frekvent. Utifrån att alla fyra företagen använde språkhandlingarna ’erbjudande’ och ’löfte’ i båda sina texter kan dessa tolkas som centrala.
