One of the aims of the study was to clarify the reliability and validity of the Job Diagnostic Survey (JDS) and the Eigenzustand (EZ) method as measures of the objective characteristics of work and short-term mental work load in the Finnish data. The reliability and validity were examined taking into consideration the theoretical backgrounds of the methods and the reliability of the measurements. The methods were used for finding out the preconditions for organisational development based on self-improvement and clarifying the impacts of working environment (organisational functioning and job characteristics) on a worker’s mental state and health. The influences were examined on a general level - regardless of individual personal or specific contextual factors. One aim was also to clarify how cognitions and emotions are intertwined and how they influence a person’s perception of the working environment. The data consisted of 15 blue-collar organisations in the public sector. The organisations were divided in target and comparison groups depending on the research frames. The data was collected by questionnaires by post. The exploratory and confirmatory factor analyses (Lisrel) were used as the main statistical methods in examining the structures of the methods and impacts between the variables. It was shown that it is possible for organisations to develop their working conditions themselves on specific preconditions. The advance of the development processes could be shown by the amount of the development activity as well as by the changes of the mental well-being (ability to act) and sick absenteeism of the personnel. It was found that the JDS and the EZ methods were reliable and valid measures in the Finnish data. It was shown that, in addition to the objective working environment (organisational functioning and job characteristics), also such a personal factor as selfesteem influences a person’s perception of mental work load. However, the influence did not seem to be direct. The importance of job satisfaction as a general indicator of perceived working conditions was emphasised. Emotional and cognitive factors were found to be functionally intertwined constituting a common factor. Organisational functioning and the characteristics of work had connections with a person’s health measured by sick absenteeism.

Tässä työssä tutkitaan eri voimansiirtokonseptien vaikutusta referenssitapauksen polttomoottorivoimalaitoksen energiatehokkuuteen ja polttoaineenkulutukseen staattisessa tilan-teessa. Referenssitapaukseksi on valittu ulkomerellä toimiva huoltoalus. Työssä esitellään dieselsähköisen laivan voimansiirtokonseptien toteutusvaihtoehtoja ja luodaan katsaus valittuihin generaattoreihin sekä taajuusmuuttajiin. Voimansiirtokonseptien hankintahintaa arvioidaan saatujen hintatietojen ja aikaisempien tutkimusten avulla. Lisäksi konseptien energian- ja polttoaineenkulutusta arvioidaan vuositasolla staattisessa tilanteessa. Perinteiselle kiinteän pyörimisnopeuden toteutukselle löydettiin haastajia sekä konseptien kuluttaman energian, että polttoaineen kannalta tarkasteltuna. Lisäksi työssä muodostetaan referenssialusta vastaava yksinkertainen simulointimalli, jolla voidaan arvioida voimalaitoksen tehohäviöitä sekä polttoaineenkulutusta eri ajotavoilla. Simulointimallilla tutkitaan myös energiavaraston tuomia etuja lisäämällä energiavarasto malliin. Mallia simuloitiin paikoitusajossa ilman energiavarastoa, sekä sen kanssa. Energiavaraston avulla saavutettiin merkittävät polttoainesäästöt.

This thesis presents a design for an asynchronous interface to Robotiq adaptive gripper s-model. Designed interface is a communication layer that works on top of modbus layer. The design contains function definitions, finite state machine and exceptions. The design was not fully implemented but enough was so that it can be used. The implementation was done with c++ in linux environment. Additionally to the implementation a simple demo program was made to show the interface is used. Also grippers closing speed and force were measured. There is also a brief introduction into robotics and robot grasping.
