modeling and simulation of processing plants are widely used in industry. construction of a mathematical model for a plant is a time-consuming and error-prone task. in light of extensive advancements in computer science (both hardware and software), computers are becoming a necessary instrument in industrial activities. many software tools for modeling, simulation and optimization of processing...

AnnAGNPS (Annualized AGricultural Non-point Source), a continuous simulation and distributed pollution model, is widely applied in evaluating non-point source pollution and watershed management practices. However, the complexity of required input data and modeling procedure keep it from being an efficient modeling tool. An integrated GIS interface was developed to facilitate organizing and prep...

Sketch-based modeling provides an intuitive and expressive interface for 3D model creation. With the Teddy [Igarashi et al. 1999] system, complex free-form 3D models could be quickly produced using a gesture interface. However, the topological modeling operations implemented in Teddy were limited by the underlying shape representation (triangle meshes). Related systems based on variational impl...

In the paper we explore the possibilities of automated test-case generation from the IFML model of application front–end. As opposed to the previous core UML standard, IFML captures the structure and properties of the application user interface, which gives us new possibilities in model–based test case generation: produced test cases have a higher probability of being consistent and of respecti...

In the past many researchers and companies have focused on mastering different multitouch interface technologies, yet there are currently still only few applications that are truly using the full capabilities of multitouch. In this paper we describe our vision for new multitouch interaction metaphors based on finger and hand gestures especially suited for 3d conceptual modeling and show some id...

Constitutive properties of living cells are able to withstand physiological environment as well as mechanical stimuli occurring within and outside the body. In this context, a quantitative study in single cell mechanics needs to be conducted. Particularly, we will examine fluid flow and Neo-Hookean deformation related to the rolling effect. A mechanical model to describe the cellular adhesion w...

Making 3D models should be an easy and intuitive task like Free-hand sketching. This paper presents iSphere, a 24 degree of freedom 3D input device. iSphere is a dodecahedron embedded with 12 capacitive sensors for pulling-out and pressing-in manipulation on 12 control points of 3D geometries. iSphere exhibits the top-down 3D modeling approach for saving mental loads of low-level machineries. U...

Usability is a core concept in HCI and is a common quality attribute for the design and evaluation of interactive systems. However, usability is a fluid construct and requires context-specific frameworks to be clearly defined and operationalized. Academic search user interfaces (SUIs) include the search portals of academic and research libraries, digital data repositories, academic data aggrega...

A unified interface that can seamlessly merge real/virtual spaces or local/remote spaces are presented as a bi-directional energy interface. An arbitrary system consisted of real/virtual objects has some energy connections between the objects of the system. These energy connections can be simply described by bond graphs. Using the mathematical modeling derived from the bond graphs of the system...

The relation between stimulus transfer and the geometry of the neuron-electrode interface can not be determined properly using electrical equivalent circuits, since current that flows from the sealing gap through the neuronal membrane is difficult to model in these circuits. Therefore, finite element modeling is proposed as a tool for linking the electrical properties of the neuronelectrode int...
