In this paper we present an environment for conceptual design which mimics the interaction of designers with physical mockups. We present novel three dimensional on-and-above-the-surface interactive techniques which combine asymmetric bimanual operations with multi-touch direct manipulation on a flat surface and depth cameras. These take advantage of a continuous interaction space to create and...

Group work frequently involves transitions between periods of active collaboration and periods of individual activity. We aim to support this typical work practice by introducing four tabletop direct-manipulation interaction techniques that can be used to transition the status of an electronic document from private to group-accessible. After presenting our four techniques release, relocate, reo...

In this position paper we present a preliminary concept of a new interaction style called personalized interfaces for multiuser, multi-display systems. Focusing on supporting colocated and collaborative interaction, based on bi-manual direct manipulation interfaces.

Teams arise in a number of important multiagent applications. Several theories of intentions for teams have been proposed. By and large, these theories tend to model team intentions exclusively on the basis of mental concepts, and fail to acknowledge the internal structure of teams. We present a formal theory of intentions for teams that considers the structure of teams explicitly. In this cont...

The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...

drought is random and nonlinear phenomenon and using linear stochastic models, nonlinear artificial neural network and hybrid models is advantaged for drought forecasting. this paper presents the performances of autoregressive integrated moving average (arima), direct multi-step neural network (dmsnn), recursive multi-step neural network (rmsnn), hybrid stochastic neural network of directive ap...
