Inom industrin används många typer av värmekällor. Det kan vara öppna lågor, IR strålning, resistiv uppvärmning eller induktionsvärmning. Induktionsvärmningen är en värmingstyp med hög energidensitet, låg investeringskostnad, snabb uppstartstid och hög flexibilitet. Ett serieresonant induktionsvärmningssystem består i sin enklaste form av en växelspänningskälla, en spole, en kondensator och objektMany different types of heat sources are used in the industry. Some of these are open flames, IR-radiation, resistive heating and induction heating. Induction heating is a heating technology that have a high energy density, fast start up times and high flexibility. A simple series resonant induction heating system consists of a voltage source, a capacitor, an inductor and the object to be heated.

Electricity differs from other commodities in that it cannot be stored. This non-storability characteristic results in traditional pricing methods for commodities not being applicable for electricity. An alternative pricing method is therefore needed and the solution is the Hourly Price Forward Curve (HPFC). The HPFC essentially gives the prices as of today for the delivery of electricity at each

Over the course of the last few years climate change has been increasingly framed in terms of security, frequently featuring in discussions and publications of various security actors and institutions. This development generated a vigorous debate within academia as to whether a securitization of climate change in global politics has occurred. By drawing upon Copenhagen School’s Securitization Theo

Modern well-insulated and highly glazed buildings experience increased overheating, even in cold climates. Buildings hold the biggest share of the world’s energy use, and current climate crisis can exacerbate future need for cooling. The study strives to analyse passive solar shadings on a south-oriented façade, having predetermined that external and internal shadings’ main function is solar heat

With the rapid and alarming rate at which forests are disappearing around the world, it is of great importance to effectively estimate loss of forest cover due to different causes. Among those causes illegal logging is a particularly enigmatic and dangerous one made well-known by the destruction of the tropical rainforests of South America and Southeast Asia. A less glamorous hotspot of illegal lo

The project’s purpose is based on how physics is applied in reality for flight safety, efficiency and sustainability purposes. The forecasting and verification of clear air turbulence(C.A.T.) is studied further to understand the demand of high-resolution forecasts by civilaviation. This was done by literature studies and interviews with pilots and meteorologists in Sweden. An alternative way of pr

Strategic thinking is a complex field that consists of more than the concept of strategy. Strategic thinking is important to business success, to maintain a competitive advantage, to strategic planning, and management decision-making. However, this is not an exhaustive list of reasons why strategic thinking is relevant. Research in the science and professional fields have failed to agree on one fi

This study is a literature review of three market-based instruments used for land management; environmental offsets, payments for ecosystem services (PES) and certification, and how they could be used to mitigate environmental impacts from sugarcane cultivation in Brazil when purchasing biopolymers. The study showed that certification is the most common market-based instrument in Brazil. Offset an

Allt fler personer har tillgång till en dator och en telefon idag. Dessa föremål har blivit en central roll i dagens samhälle och utbudet ökar. Över åren så har elektroniken blivit billigare och mer kraftfull vilket har lett till alla personer nu har tillgång till dessa föremål. En nyckel del till det är evolutionen av transistorn. Transistorn har funnits i många år men när den uppfanns så var denModern electronics are becoming more powerful and energy efficient for every new process generation. A key component in electronics is the transistor, which has made this trend possible. For many years the transistor has simply been scaled down.However, that is not possible any longer. To continue improving the transistor, new structures and materials need to be researched. A promising topic in th

Abstract Introduction: This paper aims to explore the alignment of managerial competencies in higher education and the labor market by conducting a Case Study on the MSc in Management (MiM) at Lund University School of Economics and Management (LUSEM). Method: Managerial competencies were identified through content analysis in entry-level management job advertisements in the Swedish Öresund regi

This paper studies the effect of corruption on four selected health outcomes, by using cross- country panel data, containing the 36 member states of OECD. The time period stretches from 1995 to 2017, extending upon previous studies by including data from more recent years. In order to estimate the effects of corruption, the paper uses Ordinary Least Squares, fixed effects and two-way fixed effects

This thesis aims to investigate the different mechanisms that Chinese companies in green industries used to acquire technological capabilities and how they changed over time. The thesis also aims to examine how the geographical pattern in outbound Chinese greenfield foreign direct investment has changed over time. By examining the inbound and outbound greenfield foreign direct investment pattern i

Den söta sanningen – en jämförelse av miljöpåverkan från socker respektive honung Studien handlar om miljöpåverkan från sockerproduktion och honungsproduktion, ett ämne som påverkar allt från biodiversitet till partikelutsläpp. Några miljöaspekter har valts ut för att undersökas på djupet och ge svar på frågan om vilket sötningsmedel som är mest miljövänligt egentligen. Miljöpåverkan från ekologHoney is generally considered to be a healthier option than white sugar, and humans can replace sugar with honey and still maintain a healthy diet. While effects on the body caused by sugar and honey have been investigated, the environmental impact of organic sugar and organic honey has not yet been investigated and compared. The purpose of this study was to perform an overview of the environmenta

Exercising leadership on the edge - this is a condition that concerns managers at ComWire in Dalborg. Due to a persistent organizational crisis which is characterized by uncertainty, doubt, and frustration, ComWire Dalborg seems to have lost some of its identity appeal. This context constitutes the foundation for our qualitative study intending to comprehend leadership in an environment where a fo

As the world population and the world economy continues increasing, theoverallconsumption in some parts of the world reach even more unsustainable proportions, which in turn leads to negative climate effects. To deal with this problem along with others, the concept circular economy has gained great importance.The aim of the circular economy is to minimize and prevent the upcoming of waste and to m

The development of new wireless cellular network technologies is always in progress. As 3G has been considered the foundation of mobile broadband, the latest generation of cellular mobile communications, that is, 5G New Radio, is expected to realize the networked society, where everyone and everything are seamlessly connected everywhere and every time. To ensure the connectivity and provide the re

Operahus runt om i Sverige är i brist på kompetenta repetitörer. Utförandet av ett klaverutdrag kräver utökad kunskap än bara tekniska färdigheter. Därför undersöker jag i denna uppsats inlärningsprocessen till en djupare förståelse till pianoreduktionen av en opera. Min metod har varit att studera bakgrund och kontext till operans framkomst, analysera librettot, textens roll i musiken och det Operas in Sweden are in short supply of competent répétiteurs. The execution of a vocal score requires additional knowledge than just technical skills. For that reason, I decided to investigate in the process of acquiring a deeper understanding to the piano reduction of an opera. The method I have been using are: studying background and context in the creation of an opera, analyse the libretto, t
