Konsten att förutspå konjunkturen - Hur användbara är enkätbaserade snabbindikatorer?

Foreseeing future changes in economic activity is of up most importance to a wide array of actors. The time lag in the presentation of official GDP statistics means that to somewhat accurately capture a tendency of where the business cycle is heading one need turn to qualitative sentiment indicators such as Purchasing Managers? Index (PMI) and official sentiment indicators for valuable clues. This thesis uses in-sample and out-of-sample methods to evaluate how well PMI and official Business Tendency Surveys (BTS) in Sweden and Denmark fair against the year-on-year growth rate of industrial production. Moreover, various Swedish regional sentiment indicators get examined and a case study of the indicator for the Öresund region is performed.

Kisa Stationsamhälle : från kyrkoby till municipalsamhälle 1895-1905

The current field of research concerning the impact of railroads in Sweden beside from the State main-line network is relatively narrow. Including cultural impact to the area narrows the results even further. The purpose of this study is to open the field even more into the local societies and to what extent the impact of the introduction of railroad might have had on smaller county villages. Sweden holds a unique position concerning ?station towns? or ?railways towns? in terms of railway policy and the industrial development in towns that were affected by the railway, as the affected towns continued development were based on a hybrid between direct democracy and adaptations of city-law policies.This study takes place in Kisa, a small town in southern Östergötland that during the beginning of the 20th century turned into a municipal community due to the building of Östra centralbanan (roughly translated Eastern central-line).

Framtiden för gamla Habo ullspinneri

This report presents an investigation and a new design of Habo Ullspinneris old industrial premises. It is based on the owners visions and wishes, two questionnaires and also considering of the historical value.Habo Ullspinneri was founded in 1882 by Frans August Johansson and was moved to the location it has today, near Hökån in Habo, three years later. The electricity that the machines in the industry needed was extracted from the small river that is placed under the building. In 1960 there was a fire and the result became the end of the industrial activity that had taken place in the building.There is no steady activity in the building at the moment. It is nowadays temporarily used as an agriculture museum and as a store room.

Inventering och riskklassning av förorenade områden i Öna och Östnor :

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik

This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

Ohälsa hos polisen : en explorativ undersökning av riskfaktorer och dess påverkan på mental ohälsa

Earlier psychological research on stress and its complex of problems has identified several factors which have shown a relation with the occurrence of a poorer mental ill-health. In this study some of these factors have been examined in 69 police officers from Stockholm, Lund and Helsingborg. In the study, police officers with high and low self reported ill-health were compared considering trait anxiety, alexithymia and posttraumatic stress symptoms.The results showed that police officers with poorer mental ill health had a significant higher degree of trait anxiety, the dimension of alexithymia difficulty identifying feelings and the PTSD-dimension avoidance and hyperarousal. The results also showed several positive relations among the variables that divided the groups. On account of the last-mentioned the results will above all be discussed in an integrating perspective..

Collaboration to address a wicked problem : the case of certified palm oil

Corporations meet complex challenges as they operate on a global market. Global multidimensional problems are referred to wicked problems and which cannot be solved only managed. In this case, of certified palm oil, palm oil production can be seen as a wicked problem due to deforestation of rainforest, land grabbing and social conflicts. There are also conflicts regarding the value and interest of palm oil. This thesis investigates the Swedish transformation for certified palm oil and how actors in the Swedish food market address this transformation to have certified palm oil in their production. The aim of this thesis is to explain enabling factors to address the governance gap of ethical sourcing in the food industry.

Bangenerering för industrirobot med 6 frihetsgrader

This thesis studies path generation for industrial robots of six degrees of freedom. A path is defined by connection of simple geometrical objects like arcs and straight lines. About each point at which the objects connect, a region, henceforth called a zone, is defined in which deviation from the defined path is permitted. The zone allows the robot to follow the path at a constant speed, but the acceleration needed may vary. Some means of calculating the zone path as to make the acceleration continuous will be presented.

Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar
