  1. 1. Coincidence Factor and Battery Energy Storage Systems for Industrial Electrical Power Supply : A Field Study of Building 178 at Scania AB, Södertälje

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lucas Wallhager; [2023]
    Keywords : Coincidence factor; Industrial electric load diversity; Velander; Normal distribution; Herman-Beta; Battery energy storage system; Sammanlagringsfaktor; Industriell elförbrukning; Velander; Herman-Beta; Batterier för energilagring;

    Abstract : Coincidence factors have been researched since the late 1800s, as they displays the ratio between the maximum coincidencental power usage of a system, and the sum of the maximum individual loads of the system. Accurate estimations of the highest coincidental power usage allow for minimal material usage when constructing substations, transformers, overhead lines, and cables for power transmission.

  3. 2. Behavior and Performance of Some Inference Tools in Beta Regression

    University essay from Uppsala universitet/Geometri och fysik

    Author : Max Raner; [2022]
    Keywords : ;

    Abstract : Finite interval data, such as proportions, concentrations or rates, often exhibits asymmetryand heteroscedasticy in a regression setting, which can cause issues when tryingto model such data using common modelling approaches. Ferrari and Cribari-Neto, 2004 proposed a modeling approach similar to a generalized linear model, inwhich the response is assumed to be beta distributed, using an alternative parameterisationin terms of a mean and a precision parameter, and then modeled via a linkfunction depending on a linear predictor.

  4. 3. Quantum Chemical Modelling for Predicting Mutagenicity

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Katarina Petrovic; [2021]
    Keywords : in silico; mutagenicity; Mutagen-X; LUMO; Ames test; in silico; mutagenicitet; Mutagen-X; LUMO; Ames test;

    Abstract : Mutageniciteten för olika ämnen bestäms vanligtvis med hjälp av konventionella in vivo och in vitro metoder. Att övergå till in silico metoder vore både etiskt och miljö- mässigt gynnsamt. Flera olika parametrar kan användas för att förutse mutagenicitet. READ MORE

  5. 4. Asset pricing and risk evaluation in the housing market : An empirical analysis of the Swedish housing market

    University essay from KTH/Fastigheter och byggande

    Author : Panagiotis Matiakis; [2019]
    Keywords : Risk assessment; Swedish housing market; asset pricing; quantitative analysis; beta modelling; causal relationship; Risk analys; Svensk bostadsmarknad; tillgångsvärdering; kvantitativ analys; beta modellering; orsakssamband;

    Abstract : During the recent years, the Swedish housing market has developed into a topic of major interest, both domestically and internationally. The sky-rocketing prices, the uprising demand together with the housing shortage, and the market bubble ongoing debate, have resulted in the discussion of risk being more relevant than ever before.

  6. 5. Modelling and Simulation of a bridge interacting with a moving vehicle system

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Rui Duan; Jingrui Yang; [2013]
    Keywords : Vehicles-bridge coupling vibration; Dynamic system; D’Alambert principle; Euler–Bernoulli beam theory; Mode superposition method; Newmark-beta method;

    Abstract : The problem about the vibration of vehicles and bridge is mainly the problem of coupling vibration between the vehicles dynamic system and bridge dynamic system. The vehicles running on the bridge at some speed can make the bridge vibrate, at the same time the vibration of the bridge will also affect the vibration of the vehicles. READ MORE
