Recent research into intelligent environments (Nixon et al., 1999; Coen, 1998) has focused primarily on systems where a single user interacts with a single intelligent space, through the use of speech, gestures, or more mundane keyboard input. These systems often ignore handling multiple people, yet much interaction occurs in a conference or meeting room, with multiple people interacting with e...

This paper introduces a reliability-based multi-objective design method for spatial truss structures. A multi-objective optimization problem has been defined considering three conflicting objective functions including truss weight, nodal deflection, and failure probability of the entire truss structure with design variables of cross sectional area of the truss members. The failure probability o...

The ornamental and medicinal saffron with high economic value encompasses a great share of non-oil exports in Iran. As a result, identification of suitable areas for saffron cultivation in Ardabil province located in northwestern part of Iran necessitate effective planning for expanding cultivation and production of this product. Given the effect of various environmental factors on growth and y...

A multi-dimensional ensemble empirical mode decomposition (MEEMD) for multidimensional data (such as images or solid with variable density) is proposed here. The decomposition is based on the applications of ensemble empirical mode decomposition (EEMD) to slices of data in each and every dimension involved. The final reconstruction of the corresponding intrinsic mode function (IMF) is based on ...

Resources potential assessment is one of the fields in geosciences, which is able to take great advantage of GIS technology as a substitution of traditional working methods. The gold resources potential in the eastern Kunlun Mountains, Qinghai Province, China was assessed by combining weights-of-evidence model with GIS spatial analysis technique. All the data sets used in this paper were derive...

Recently standardized wireless systems have multiple Time-Slots in a radio frame, but existing MUMIMO schedulers are not utilizing multiple Time-Slots efficiently. In this paper we propose a sub-optimal user grouping algorithm utilizing multiple Time-Slots efficiently. The proposed algorithm disperses highly-correlated users in different Time-Slots to prevent severe degradation of spatial multi...

In this report we show how proper cooperation among radio nodes may provide diversity gain, also for single antenna systems. We consider first the connectivity of a wireless network and show how it can benefit from cooperation. Then, we consider some specific forms of cooperations, based on distributed space-time coding, in both single and multi-user contexts. Finally, we pay a special attentio...

Association rules discovery is a fundamental task in spatial data mining where data are naturally described at multiple levels of granularity. ARES is a spatial data mining system that takes advantage from this taxonomic knowledge on spatial data to mine multi-level spatial association rules. A large amount of rules is typically discovered even from small set of spatial data. In this paper we p...

Travel demand analysis is intrinsically spatial; yet spatial analysis considerations are seldom recognized and accommodated in travel modeling. The objective of this paper is to identify the spatial issues that need to be recognized in demand modeling, and to propose a multi-level, mixed logit, formulation to address these spatial issues in the context of activity stop generation. The multi-lev...

in recent decades, as a result of population growth, industrial developments, scarcity of sources, etc. more attention has been paid to spatial planning. spatial planning needs the consideration of different goals, scenarios, criterions and constraints, which leads us to the usage of spatial multi-criteria decision analysis (mcda) methods. the mail goal of this research is to develop a novel mo...
