This article applies the history of emotions lens to study the emotions experienced by the ‘comfort women’ in the Japanese Empire. Emotions have been a long-neglected aspect in the study of military sexual violence. The article examines how a mélange of positive and negative emotions enabled those women to exercise some limited agency in a confined and tightly regulated space and, in some rare cas

This thesis investigates what mechanisms that contribute to the interaction between lateral and vertical dynamics in a fourwheeled vehicle. For this a vehicle model was derived. To capture all the essential dynamics of the vehicle, both a horizontal model and a vertical model was used. The interaction between the models turned out to be quite evident, making it possible to use the active suspensio

A previous paper addressed the "PI+p" controller (a PI augmented with an additional, stable pole) and demonstrated its advantages over standard PIs, particularly if tuned with a combined model-relay-based method along the "contextual" approach proposed in another recent work. This manuscript extends the scenario to the PID+p structure, with obvious meaning, and applies the contextual approach to i

This paper presents new tuning rules for PIDcontrollers based on loop shaping. Previous research has shownthat maximization of the integral gain subject to constraints on the maximumsensitivity is an efficient design method for PI controllers, but thatadditional constraints are needed for design of PID controllers. Inthis paper, an additional constraint is obtained by restricting theratio between

This paper describes new simple tuning rules for design of feedforward compensators. The problem of feedforward from load disturbances is analyzed, and it is shown that the feedback controller should be taken into account in the feedforward design process. Simple rules based on IAE minimization with restrictions on the process output overshoot and the high-frequency gain of the compensator are the

Design rules for optimal feedforward controllers with lead-lag structure in the presence of measurable disturbances are presented. The design rules are based on stable first-order models with time delays, FOTD, and are optimal in the sense of minimizing the integrated-squared error. The rules are derived for an open-loop setting, considering a step disturbance. This paper also discusses a general

A method for assessing disturbances in SISO loops has been developed. The method indicates if the SISO loop under consideration will benefit from an addition of feedforward control from a measured disturbance. An implementation in Java of the methodology is presented in the paper.

The purpose of this thesis is to look into the knowledge city concept and the preferences and requirements of companies on such a city. Furthermore, suggestions of ideal conditions in a knowledge city are proposed. The thesis has been conducted through a qualitative approach where a deductive procedure has been implemented. In order to examine knowledge cities, Barcelona has sketchily been looked

In November 2018, the Danish government passed a bill that introduced the category ‘severe ghetto’ to the law on non-profit housing. Moreover, the bill prescribes extraordinary policy measures in the targeted areas in order to encourage urban regeneration. The non-profit housing associations in ‘severe ghettos’ are forced to reduce the share of non-profit housing stock to 40% through relabelling,

In recent years, women entrepreneurship has received much attention from both economic policy-makers and entrepreneurship researchers - women entrepreneurs are considered important for inno-vation and thus economic development. This is manifested in an increasing interest in, and a prolif-eration of writings on, the topic. A number of studies undertaken in recent years to investigate women entrepr

This paper describes several adaptive techniques based on frequency response analysis, which are used in industrial controllers. Automatic tuning is used to obtain PID controller parameters, to build up gain schedules, and to initialize adaptive algorithms. A simple adaptive feedback algorithm which is based on the idea of tracking a point on the Nyquist curve is presented as well as an adaptive f

This thesis examines the transformation of Finnish international identity between Finland’s accession to the EU in 1995 and its membership in NATO in 2023. The study is significant as Finland’s NATO accession has frequently been portrayed as a sudden and unprecedented rupture in Finnish foreign and security policy following Russia’s full-scale invasion of Ukraine in 2022. Challenging this interpre

This paper proposes a closed-loop propofol admission strategy for depth of hypnosis control in anesthesia. A population-based, robustly tuned controller brings the patient to a desired level of hypnosis. The novelty lies in individualizing the controller once a stable level of hypnosis is reached. This is based on the identified patient parameters and enhances suppression of output disturbances, r

The development seen within industrial automation in recent years enables the emergence of manufacturing sites that utilise technology for improved productivity, quality and safety. Increased communication demands introduced by Industry 4.0 have motivated the development of cloud-fog automation; a technique characterised by wireless communication between lower levels of the automation pyramid.

This paper offers a two-zone NOx model suitable for vehicle on-board, on-line implementation. Similar NOx modeling attempts have previously been undertaken. The hereby suggested method does however offer clear and important benefits over the previously methods, utilizing a significantly different method to handle temperature calculations within the (two) different zones avoiding iterative computat
