A novel approach to uncertainty assessment, known as the NUSAP method (Numeral Unit Spread Assessment Pedigree) has been applied to assess qualitative and quantitative uncertainties in three case studies with increasing complexity: (1) the monitoring of VOC emissions from paint in the Netherlands, (2) the TIMER energy model, and (3) two environmental indicators from the Netherlands 5th Environm...

One of the key elements in LTE (Long Term Evolution) networks is deployment of multiple femtocells for improvement coverage and data rate. However, arbitrary overlapping coverage of these cells makes the HO (handover) mechanism complex and challenging. In this paper, simulations of deploying LTE femtocells in a scenario were evaluated. With this objective, measure impact and correlation of the ...

Public organizations show growing interest in the development of dashboards that aid relief agency managers in crisis preparation. Yet, there is a dearth of research on the development of such dashboards. This paper discusses the experiences gained from a pioneering Living Lab on the development and evaluation of dashboards for assessing crisis preparedness. In order to evaluate and further imp...

Reliability of public transport systems has been considered critically important by public transport users, operators and the government. Lack of reliability in public transport results in uncertainty and delays aggravating anxiety and discomfort for the passengers and increases costs due to lost mileage and lower fleet utilisation for the operators. The government emphasises a reliable bus-ser...

Financial engineering such as trading decision is an emerging research area and also has great commercial potentials. A successful stock buying/selling generally occurs near price trend turning point. Traditional technical analysis relies on some statistics (i.e. technical indicators) to predict turning point of the trend. However, these indicators can not guarantee the accuracy of prediction i...

truncated gaussian simulation (tgs) is a well-known method to generate realizations of the ore domains located in a spatial sequence. in geostatistical framework geological domains are normally utilized for stationary assumption. the ability to measure the uncertainty in the exact locations of the boundaries among different geological units is a common challenge for practitioners. as a simple a...

Introduction: The increasing cost of health care in developed and developing economies has called for a change in the way health activities are implemented. Nigeria is faced with fundamental health care related challenges coupled with recent security issues. Uncertainty prevails as health system dynamics unfolds. Objectives: To explore the relationship between environmental uncertainty and heal...

The correlations among indicators of objective well-being, cultural dimensions, and subjective well-being were investigated using Organisation for Economic Co-operation and Development (OECD) data from 35 countries. The subjective well-being measures included life satisfaction as well as six positive and six negative indexes of experience. Positive and negative experience scores were subjected ...

This article discusses Oppenheimer's theory on marriage timing, reviews the way this theory was received in European demography and family sociology, and develops a new test of the theory using annual panel data from 13 European countries for the period 1994-2001. Several indicators of men's economic status are used, including school enrollment, employment, type of labor contract, work experien...
