The internship is dedicated to the modeling of RF and electrical performances of a 250 W Ka traveling- wave tube, using computation codes developed internally. The objective was to compare simulations and measurements in order to design a 5-stages collector. The modeling of the interaction wave -beam (RF model) is discussed in the first part. Simulations are done with the internal code MVTRAD. In p

Both energy security and the demand for energy, particularly from renewable energy sources, as principle drivers, call for the investigation of renewable energy potential in Poland. The city of Zabrze, located in the Upper Silesia province and urban zone of Katowice, dedicates continuous efforts to the improvement of its waste management against the background of European Union Directives requirin

“Energy Futures Øresund” is the final report on the energy system of the Øresund Region. It comprises a regional overview of the current state and trends of selected energy systems, discussions on potential technological solutions to overcome barriers and an analysis of the energy strategy of the island Bornholm. The report forms the basis for further strategic energy planning of Energi Öresund, a

In this bachelor thesis I study the prevalence of taqiyya among a group of Swedish Muslims belonging to the Twelver Shia sect. Furthermore I examine their opinions regarding its use and whether taqiyya is relevant in a contemporary Swedish context. Beside the empirical study, I use social theories to examine how the individual relates to their own right to religious interpretation outside the para

Den så kallade multikanals-strategin myntades redan på 90-talet som ett sätt att beskriva återförsäljares användning av två eller mer kanaler för att sälja produkter och tjänster till kunder. I mitten på det första årtiondet började det här begreppet att evolvera på grund av framväxande diskussioner kring integration mellan säljkanalerna. Det här ledde till introduceringen av omni-kanalsstrategin.The so called multi-channel strategy was coined back in the 90's as a way to describe retailers' use of two or more channels for selling products and services to customers. In the middle of the first decade this concept started to evolve, due to emerging topics around integration between the sales channels. This ultimately led to the introduction of the omni-channel approach. Its main idea

Purpose: Based on excisting theories within marketing and psychology research investigate how scent marketing can affect customers and whether attitudes towards an ambient scent differ between men and women. Methodology: A quantitative study has been conducted with its starting point in positivism. A deductive approach has been used, meaning that a theory is being proven or disproven using a spec

“Strategic Energy Solutions” is the final report on energy solutions for a zero emission Öresund region. It consists of numerous solutions that have been, or can be, applied in the region in order to minimise the environmental impact of the energy sector. Additionally it includes a case study of energy transition projects on Lolland Island in Denmark. The report seeks to provide recommendations fo

During the recent decades, concerns about the environment and climate change have progressively gained importance in political, social and economic arenas. Amid environmental conferences and international political negotiations, on the business side corporations have scrambled to find ways to secure themselves and even prosper on an environmentally aware consumer base. This thesis examines how Ik

“The Future is distributed: a vision of sustainable economies” is a collection of case studies on distributed economies, a concept describing sustainable alternatives to the existing business models. The authors of this publication are international Masters students of the Environmental Sciences, Policy and Management Programme at the International Institute for Industrial Environmental Economics

Enzymer är biologiskt aktiva molekyler med en katalytisk förmåga. Detta innebär enzym kan medföra en omvandling av ett ämne i en reaktion som normalt inte sker spontant. Laccas är ett enzym som kan bryta ner (oxidera) fenolföreningar, och i naturen förekommer det i växter, svampar och bakterier där det fyller olika funktioner.In order to broaden the use of laccase and increase its economic practicability for industrial oxidative processes, we have immobilized the enzyme in cross-linked enzyme aggregates (CLEA). The immobilization was carried out in two steps consisting of 1) precipitation- and 2) cross-linking of the enzymes. A factorial design was used in order to reveal the importance of different process parameters

This thesis and technical report concentrates on distributed control using a distributed model predictive scheme. The model of a two room house and three room houses is build and a distributed model predictive control (MPC) algorithm is implemented in order to reach specified room temperatures with minimized energy effort in each room. For reference tracking Target Calculation and the delta input

Model-Based Design is a development method that is becoming popular to use when creating control systems. In this thesis a demonstration of the advantages of using this method is made for Combine Control Systems AB. The 3D simulation software IndustrialPhysics is used to represent a real process in form of a gantry crane. A controller for this crane is developed in Simulink and Model-in-the-Loop (

The integration of multiple data sources and the convergence of process control systems and business intelligence layer such as the enterprise resource planning (ERP) are paving the way for important progress in plant operation optimization. Numerous companies offer “Analytics Services” to leverage this newly available mine of data but applications still appear to be limited to certain specific t

In Nampula Province, Mozambique, locating productive wells is a problem due to the heterogeneity in local geology, which consists of mainly weathered crystalline rock. This study estimates hydraulic conductivity of 10 hand pumped water wells in rural areas of Nampula Province using slug tests, and is a follow up of Andersson and Björnström (2013) and of Enkel and Sjöstrand (2013). This thesis aim

Zabrze is a medium size town of 200 000 inhabitants in the region of Upper Silesia, Poland. The development of the town was originally based on the exploitation of heavy industries. In the past few years Zabrze has, however, moved towards more service and tourism oriented industries. As part of this journey, the city of Zabrze sees the need to improve its existing waste management system. This rep

We present simulations done on the onset of common envelope evolution with giant donors by taking into account the mass loss through the outer Lagrange point and the forming of the common envelope. In addition we apply proper stellar models and evolve our simulations using an Runge-Kutta integrator with adaptive step-size. We show that each of these processes are significant in the onset of common

The Modelica language is an object-oriented, equation-based language used for modeling and design in many different domains and for various physical applications. In order to exchange models both between Modelicabased tools and other tools the Functional Mock-up Interface (FMI) has emerged. This interface enables exchange of virtual models between manufacturers and/or divisions within a company. T
