In this paper we prove fixed point theorems for multivalued mappings in ordered topological spaces. Fixed point results in ordered function spaces and in product spaces, and applications to game theory, are also presented.
In this paper we prove fixed point theorems for set-valued mappings in products of posets. Applications to the theory of Nash equilibria are presented.
Preface Infinite praise definitely goes to God Almighty, Who has given me strengths to accept and achieve this challenging task. I wish to thank my thesis supervisors, Professor Aarne Halme and Professor Kalevi Hyyppä for their expert comments and kind guidance. I would really like to thank my instructor Seppo Heikkilä for his kind support and time through… (More)
The objective was to carry out a clinical assessment of different cervical mobility measurements in ankylosing spondylitis (AS), including two new tape methods for measuring cervical rotation and lateral bending. A range of cervical movements was measured in 52 consecutive male AS patients and the results correlated with detailed radiological changes in the… (More)
Different spinal ranges of motion (ROM) were measured and the results of 17 repeated tests correlated with spinal radiological changes in 52 male patients with ankylosing spondylitis (AS). Both Schober tests and measurements of lumbar and cervical rotations (TRi, TR, CR, CRt) and lateral flexions (LFLf, LFLx, CLFLt, CLFLm), together with thoracolumbar… (More)
This paper presents a comparison of three different speech based task communication methods using a simulated astronaut-robot geological exploration mission as a test case. The conventional task communication method, in which the astronaut needs to communicate both the action and target, is compared against communication methods where object affordances,… (More)
Space of two categories connects wievers emotionally with their own childhood. Each person entering the installation space creates a human-shaped view to the world of a little girl with their own shadows. The shadows act as gateways to another temporal state, which is illuminated inside shadows, normally dark and void. The installation deals with the… (More)
The aim of the study was to compare and evaluate the usefulness of Finnish versions of two functional indices used in spondylarthropathies. Seventy consecutive inpatients with different kinds of spondylarthropathies filled in self-administered questionnaires: the Bath Ankylosing Spondylitis Functional Index (BASFI) and the Dougados Functional Index for… (More)
