This paper presents and discusses findings from a study where the use of enterprise modeling has been empirically investigated in eight combined process change and information technology initiatives. Artifacts, guidelines and tools used in enterprise modeling practice are identified. We identify three types of barriers to enterprise modeling: Challenges, Resistance and Moderators. We compare th...

What are the determinants of consumer choice over payment mechanisms? The answer to this question is important for a variety of reasons. Every government has the responsibility of supporting an efficient and effective payment system. Doing so is an explicit mandate of the Federal Reserve Bank in the United States. In addition, nothing is more central to private sector commerce than collecting p...

Recent financial research has provided evidence on the predictability of asset returns. In this paper we consider the results contained in Pesaran-Timmerman(1995), which provided evidence on predictability over the sample 1959-1992. We show that the extension of the sample to the nineties weakens considerably the statistical and economic significance of the predictability of stock returns based...

Several approaches have been introduced in literature for active noise control (ANC)systems. Since Filtered-x-Least Mean Square (FxLMS) algorithm appears to be the best choice as acontroller filter. Researchers tend to improve performance of ANC systems by enhancing andmodifying this algorithm. This paper proposes a new version of FxLMS algorithm. In many ANCapplications an online secondary pat...

Despite traditional four-step model is the most prominent model in majority of travel demand analysis, it does not represent the potential correlations within different travel dimensions. As a result, some researches have suggested the use of choice modelling instead. However, most of them have represented travel dimensions individually rather than jointly. This research aims to fill this gap t...

Wheeled mobile manipulators utilize both the locomotion capabilities of the wheeled platform and manipulation capacity of the arm. While the modelling and control of such systems have previously been studied, most of them have considered robots with rigid suspension and their wheels are subject to pure rolling conditions. To relax the aforementioned limiting assumptions, this research addresses...

Resources/reserves classification is crucial for block model creation utilised in mine planning and feasibility study. Selection of estimation methods is an essential part of mineral exploration and mining activities. In other word, resources classification is an issue for mining companies, investors, financial institutions and authorities, but it remains subject to some confusion. The aim of t...

The present study aims to predict the potential geographic distribution and future expansion of invasive alien lionfish (Pterois miles) with ecological niche modelling along the Mediterranean Sea. The primary data consisted of occurrence points of P. miles in the Mediterranean and marine climatic data layers were collected from global databases. All the used models run 100% su...
