An antenna is one of the most fundamental elements of wireless communication systems. The radiation behavior of antennas is characterized with the aid of the farfield radiation pattern. In this thesis, a near-field antenna measurement system is designed to predict the far-field pattern of antenna operational frequency 28 GHz and 39 GHz. The near-field measurement system operates by measuring ma

The industrial sector in Sweden accounted for 38 percent of the country’s total energy consumption in 2019. As the world’s focus has shifted drastically on energy consumption, the industry sector’s has as well due to energy initiatives and government-driven regulations. The energy issue is currently of great relevance for energy-intensive industries where enormous potential remains due to factors

Is the general perception that Swedish news always conveys a true picture of reality and that the news is always credible? National security and military threats are today an essential part of the security policy agenda. The nature of the world around us has changed significantly in recent months and Sweden's security policy is directly affected by developments in the world around us. The rap

The aim of this thesis is to further develop the understanding of how different parameters related to the gasket groove of a heat exchanger affect the mechanical performance of the product. Three different parameters with two different gasket materials were evaluated. Comparisons between the parameters where mainly made in terms of contact- and leakage pressure but phenomena related to factors suc

The Swedish armed forces have struggled with recruitment of military personnel for several years. Despite the facts that the military units have equal opportunities to succeed in recruitment, some regiments do better than others. This may be due to difference of the sub-cultures within each military unit. This study examines whether there is a connection between personnel supply and cultures in mi

This essay provides an insight into the situation in Israel today linked to the initial plan from 1947, on the division of the land area into a Jewish part and an Arab part. The area is characterized by armed conflicts both historically and in modern times. Four major Arab-Israeli wars have raged since the declaration of the state of Israel in 1948. Unrest is still raging along the Israel-Gaza-Wes

Human errors happen all the time, everywhere in the world. Most of the errors are corrected before there is an accident. But in a high risk organization such as the military there are often bigger consequences when an accident happens. This case thesis aims to investigate a connection between experience and the human factor complacency in the Swedish armed forces. It also aims to highlight complac

Stigande energianvändning och global uppvärmning har lett till en ökad efterfrågan av förnyel-sebara energikällor. Ett alternativ är att utnyttja avloppsvatten för att producera biogas. Avlopps-vatten kan därav ses som en resurs snarare än avfall. I biogasproduktion används anaerob ned-brytning där mikroorganismer bryter ner organiskt material till metan. Primär rening är första steget inom avlopThe global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. Biogas production is based on anaerobic digestion where micr

This case study seeks to understand why non-commissioned officers (NCOs) in the Swedish armed forces decides to leave the organization. The study uses two different theories; Herzbergs two factor theory which focus on work motivation and a theory called Job embeddedness which tries to explain voluntary turnovers and what makes employees stay or leave. The empirical material is gathered through dee

In the early 20th century liberalism had an upswing. New treaties were signed, and the everlasting peace had finally arrived. In the Far East, Japan was emerging from an agricultural society and making major leaps toward industrialization. They had huge demands in recourses like oil and steel. As an emerging power Japan wanted to compare themselves with USA, Great Britain, and Germany. Their imper

Åland's status as a demilitarized and neutralized zone has achieved customary status and is defended by all parties involved. The Åland solution was historically a way of disarming the risks of a militarized and fortified Åland in a way that all parties could accept. But at the same time, demilitarization means that the military threshold for an attack is low, which in itself creates security

Sweden is currently without a functioning system to secure the supply of food in crisis and war. After the Cold War, the security policy orientation was characterized by peace, disarmament and the dismantling of both civilian and military readiness capabilities. The former assessment that Russia could not pose a threat to Sweden and our neighbouring countries has recently fundamentally changed. Th

In this study, the reagent 3,5-dinitrosalicylic acid (DNS) and high-performance anion exchange chromatography (HPAEC) were used for carbohydrate characterisation. It was revealed that the DNS reaction is not exclusive to reducing ends as commonly thought, but rather that the reagent reacts with other parts of the carbohydrate molecules as well. HPAEC analysis was used to find how the product distr

The purpose of this Essay is to study whether Swedish Army Officers of today are less prepared for an armed conflict than their older colleagues. The study is a text analysis of Meir Finkel’s theory on Cognitive and Command Flexibility, Swedish military Doctrines and other relevant documents. A research report put together by Swedish Defence Research Agency examining the process of career developm

In 2016 Max Abrahms and Justin Conrad published a study that resulted in a theory regarding anonymous terrorist attacks. Terrorism is a political communication strategy used by groups to communicate their grievances and the cost of ignoring them. In practice, however, terrorist groups only take responsibility for a small fraction of all attacks. Terrorist leaders are not honored for the violence a

What was it that prompted a security policy-differentiated action between Sweden and Denmark as a counter action to the Russian power built up with landing ships in the Baltic Sea region mid-January 2022? This study will try to provide answers to this. We look at it as a comparative case study with two of Keren Yarhi-Milo´s theories from the book The Behavior thesis: Knowing the adversary from 201

In the Swedish Armed Forces (SAF) only few female naval officers reach the position of Commanding Officer (CO) of a naval warship. This, even though the percentage of female officers in the Navy is high compared to the entire SAF. This hampers SAF equality ambitions because a command on the lower levels is a stepping-stone towards higher leadership positions. In this student paper eight female nav

The purpose of this study is to survey the Swedish peoples trust to welfare from the perspective of the changes that have occurred since 1986. Have these changes affected Swedish peoples view of the welfare state and of the state itself?
