In this study artificial neural networks (ANNs) are utilized for time series forecasting. Analyzed time series includes two Google AdWords metrics and revenue for an e-commerce. Classes of ANNs included in the analysis are feedforward multilayer perceptron’s and two types of recurrent neural networks (RNNs), specifically Jordan- and Elman neural networks. Since ANNs lack econometric interpretation
Tidigare forskning har visat på en lång rad förmåner kopplade till skönhet och minst lika många nackdelar kopplade till fulhet. Hur skönhet (vad människor uppfattar som skönt hos andra) uppfattas och definieras har dock beskrivits som en till stora delar obesvarad fråga, lämnad i en konceptuell svart låda. De försök som gjorts att definiera innehållet i den svarta lådan har huvudsakligen utgått fr
Arsenik är ett mycket giftigt ämne som finns i berg, mark och grundvatten, och är känt för att orsaka allvarliga hälsoeffekter. Neurologiska skador hos människan inträffar vid koncentrationer så låga som 100 μg/L, medan 1–3 mg/kg kroppsvikt As är en dödlig dos. Exponering för As kan leda till bland annat cell- och DNA-skador, ett antal sjukdomar och störningar samt olika typer av cancer. Höga As-kArsenic is a very toxic element present in rocks, soils, and natural groundwater, and known to cause serious health effects. Neurological damage is known in humans to occur at concentrations as low as 100 μg/L, while 1–3 mg/kg of body weight As is a lethal dose. Exposure to As may lead to e.g. cellular injury and DNA damage, a number of diseases and disorders and several types of cancer. High conc
En revisor har till uppgift att granska aktiebolagets redovisning och bolagsledningens förvaltning enligt 9 kap. 3 § ABL. Den ekonomiska informationen som bolagen ställer ut för tänkbara intressenter i samhället är avgörande för ett fungerande näringsliv. Syftet med revisorns revision är att styrka dels den ekonomiska informationen bolaget har lämnat, men även förvaltningen av företaget för att ökAn auditor has the task of examine the annual report and company's accounts and management of the company according to chapter 9. 3§ ABL. The financial information that companies face for potential stakeholders in society is crucial for a functioning financial community. The purpose of the auditor's inspection is to strengthen the economic information the company has provided, but also the
Recent advances in artificial intelligence have enabled machines to take over many of the tasks that could previously only be carried out by humans. This trend is expected to continue, urging political theory to propose ideas for how the organization of society can be adapted accordingly. Drawing upon John Rawls’s theory of justice, this thesis argues that automation can be instrumental in bringin
This is a M.Sc. thesis investigating the compatibility and performance of a regime switching framework as a complement to the Black-Litterman portfolio allocation model. Conclusively, it is considered to be a compatible match of models in terms of practical implementation and the results indicate that the model is performing well.
In a competitive market like electricity retailing it is crucial for energy providers to estimate risk and cost for ?xed price contracts in order to set competitive but not unpro?table prices. This report calculate three price components that covers the wholesale and retail costs. Pro?le price com- ponent is the expected electricity load to the expected spot prices in every hour in the delivery pe
The extreme value theory has been applied on daily rainfall in the five most exposed areas of Bangladesh between the years 1980-2016 in order to esti- mate extreme rainfalls for the next 10, 50 and 100 years. These types of computations are necessary for optimising planning and preparations for ex- treme future rainfalls which can lead to minimising property damage and ultimately saving lives. Gen
The idea behind Sweden’s export of war material consists of two main arguments. The first is based in Sweden’s policy on neutrality and states that export is needed to enable independence for Sweden’s defence. The second is that the export leads to many jobs in rural areas in Sweden and that a ban would lead to large unemployment. This thesis examines these two arguments by applying an idea critic
I svenska domstolar utvecklades under en period av över 30 år en påföljds-praxis i narkotikamål som i hög grad avvek från vad som gäller för andra brottstyper. Straffvärdebedömningen inom området styrdes i princip helt och hållet av tabeller grundade på arten och mängden narkotika. En omfattande praxisomläggning ägde rum åren 2011 till 2013. Omläggningen medförde att samtliga relevanta omständigheIn Swedish courts, over a period of more than 30 years, a practice of punishment was developed in drug cases, which largely differed from those of other types of crime. The penal value assessment in the area was basically governed entirely by tables based on the art and amount of drugs. A comprehensive practice review took place between 2011 and 2013. The conclusion was that all relevant circumsta
By understanding politics as something that public institutions do one can find a political problem in the public sectors inability to staff positions vital to the function of these institutions. The case that was studied revolves around the expected lack of officers in the Swedish defense. Earlier research regarding the staffing of occupations within the public sector points to a professions attr
Bakgrund Patienter kan i samband med magnetresonanstomografi drabbas av ångest, vilket innebär ett ökat vårdlidande och kan resultera i avbrutna undersökningar och därtill en ökad kostnad för vården. Syfte Litteraturstudien utfördes för att undersöka om utökad information har betydelse för ångest hos patienter i samband med en magnetresonanstomografi. Metod En litteraturstudie genomfördes där åtta
The masters thesis The particular politics of the home - domestication and parental practices of digital games in everyday life aims at providing a closer look at how games played on phones, consoles or computers are regulated within the everyday of family life. Through semi-structured interviews with nine parents, the author creates understanding for how digital games are not only tied to the mor
This thesis aims to contribute to the growing field of research on migrant transnationalism by analyzing immigrant organizations among Bosnian immigrants in Sweden. The main focus of the study is on the effects of the immigrant transnationalism phenomenon for socio-economic development within home communities by investigating and analyzing the structures and processes that allow transnational acti
Female sex workers in Malawi are exposed to multiple occupational health and safety risks. Despite the fact that FSWs are impacting the general public’s health status, health care access is limited due to different challenges. In order to identify the barriers and receive a deeper understanding of the experiences FSWs make when accessing health care and how these experiences impact the women’s age
The purpose of this thesis was to explore how a scholarship distributed to upper secondary school students of ethnic minority in Ratanakiri, Cambodia has promoted educational participation. To do this, this thesis analysed students’ understanding of the value of education, obstacles to participation and how the scholarship has addressed these obstacles. A qualitative approach was used where data w
This thesis set the goal to contribute to the fields of diaspora studies and cultural studies from a media and communication studies angle by addressing the blank spots ‘white minorities’ and book use. White diasporas are nearly invisible within academia and very often ‘under the radar’ in society as well. Books are underresearched within media studies in favour of other media. On the other hand,
A shift in power has been definite since the introduction of news sharing on social media. The ability to control distribution of news and information has been transferred from large media organisations to acting individuals presented as creators of public opinion. A new kind of gatekeepers have been introduced and a vast majority of different verities now have an opportunity for unrestricted dist
With the wide-ranging crisis in Venezuela exacerbating since 2014 and Chile consolidating its leading economic position within Latin America, the number of Venezuelan immigrants in Chile has significantly grown. This paper aims to understand the push and pull factors of Venezuelans migrating to Chile and their perceived integration. The broader purpose is to better understand the push and pull fac
