An interaction form is an abstract model of interaction based on a description of power distribution among agents over alternatives. A solution known as the settlement set is defined at any preference profile. Necessary and sufficient conditions for stability, that is the existence of settlements, are established. A Stability Index that plays a role similar to that of the Nakamura Number is def...

The influence of rotation and magnetic fields on the physical properties of isothermal gas clouds is discussed. The presence of rotation and/or magnetic fields results in an increase of the critical cloud mass with respect to gravitational instability for clouds of a given temperature and external pressure. Rotating clouds have higher densities. Consequently, they are more stable against tidal ...

A study was undertaken in southern peninsular state of India, the Tamil Nadu State, to assess the farmers’ “Willingness to pay” (WTP) for receiving annual health care services to their dairy animals. The districts of the state were categorized as “Livestock developed” (LD) and “Livestock under developed” (LUD) based on initial base line developed. Contingent valuation (CV) approach was used to ...

This paper describes a novel application of Fiber Braggs Grating (FBG) sensors in the assessment of human postural stability and balance on an unstable platform. In this work, FBG sensor Stability Analyzing Device (FBGSAD) is developed for measurement of plantar strain to assess the postural stability of subjects on unstable platforms during different stances in eyes open and eyes closed condit...

Members of dispersed work teams may be located geographically in a variety of configurations. In fully-dispersed teams, each member resides in a unique location, whereas partially-dispersed teams are composed of some colocated and some distant members. Configurations in which team members are divided into geographically-distinct subgroups may create faultline dynamics, characterized by disrupti...

Research into computer support for colocated small group meetings has not delivered any significant benefit in spite of significant investment and decades of research. We suggest that the focus has been on the wrong problem. Each time a process is enacted in small group work it will different (even if only slightly different) due to the situational context. Therefore the process for supporting ...

Academic dissertation To be presented, with permission of the Faculty of Biosciences of the University of Helsinki, for public criticism in the lecture hall 2 of Viikki Information Centre (Viikinkaari 11) on December 2 nd 2006 at 12 o'clock noon.

OBJECTIVES To test a hypothesis that patients with Parkinson's disease may not notice discrepancies between their perceived and actual stability limits and cannot keep their centre of gravity within the stability region. SETTINGS Outpatients with neurological disorders in rehabilitation service. SUBJECTS Twenty-one patients with Parkinson's disease (11 men, 10 women; mean duration 5.9 +/- 3...

Tractor overturning remains a serious problem in agricultural activities. A detailed analysis of problems and causes leading to a tractor overturn have revealed that by improving tractor’s static stability we can positively infl uence the safety as early as during the concept phase. We designed a mathematical model and a numerical simulation of the static stability of a tractor with an oscillat...
