Survey on the virtual commissioning of manufacturing systems

Chi G. Lee, Sang C. Park
2014 Journal of Computational Design and Engineering  
Two main issues are identified, the physical model construction of a virtual device, and the logical model construction of a virtual device.  ...  The expected benefits of virtual commissioning are the reduction of debugging and correction efforts during the subsequent real commissioning stage.  ...  Acknowledgments This work was partially supported by the Agency for Defense Development (UD120035JD, UD110006MD), and the Natural Research Foundation grant (2010-0021040) funded by the Ministry of Education  ...

Modelling Devices for Natural Interaction

Alan Dix, Masitah Ghazali, Devina Ramduny-Ellis
2008 Electronical Notes in Theoretical Computer Science  
One aspect of our studies has been to try and unpack which properties of physical interaction are essential to make them comprehensible, and which can be relaxed [5, 9, 10] .  ...  We do not interact with systems without first performing some physical action on a physical device.  ...  Either of these conditions may be broken, but that would suggest that some aspect of the physical device is not being fully utilised, or some signal from the logical device is being ignored.  ...

Physigrams: modelling devices for natural interaction

Alan Dix, Masitah Ghazali, Steve Gill, Joanna Hare, Devina Ramduny-Ellis
2008 Formal Aspects of Computing  
This paper explores the formal specification of the physical behaviour of devices 'unplugged' from their digital effects.  ...  By doing this we seek to better understand the nature of physical interaction and the way this can be exploited to improve the design of hybrid devices with both physical and digital features.  ...  Acknowledgments This work has been supported by the AHRC/EPSRC funded project DEPtH 'Designing for Physicality' (http:// www.physicality.org/), part of the joint AHRC/EPSRC research initiative 'Designing  ...

2005 Software engineering notes  
As consequence of this trend everyone has a lot of small or invisible devices in his direct environment, e.g. mobile phones, PDAs, or music players.  ...  In this paper we describe both an architecture supporting the integration of heterogeneous mobile devices at runtime and a concrete implementation.  ...  In section 3 the logical architecture of the AmI system is described. Section 4 deals with the realization of the logical architecture within a given physical setting.  ...

Analysis of Physicality Aspects in Physical User Interfaces of Embedded Systems

Mahmood Ashraf, Masitah Ghazali
2013 Jurnal Teknologi  
Negligence towards the interaction aspects of physical interface is resulting in the generation of interaction complexities for the user.  ...  The result analysis highlights the significance of exposed state, tangible transition, and inverse action over other physicality aspects.  ...  Thirdly, during the operation, anytime the user may know the internal (logical) state of the device by looking at the physical state.  ...

The effect of the geometry aspect ratio on the silicon ellipse-shaped surrounding- gate field-effect transistor and circuit

Yiming Li, Chih-Hong Hwang
2009 Semiconductor Science and Technology  
In analog circuits, the device with an aspect ratio of less than 1 is promising because the short-channel effect is suppressed.  ...  Thus, a device with a large aspect ratio, such as 2, will be more suitable for digital applications.  ...  from 10% of the logical '1' level to 90% of the logical '1' level, as presented in insets of figures 9(a) and (b).  ...

1984 Computer Performance  
Most of this work, however, has dealt primarily with only one aspect of program behaviour, namely, memory reference behaviour.  ...  In addition, it is possible (at least in principle) to obtain the physical 1/O behaviour, either analytically or by simulation, from the knowledge of the logical 1/O behaviour and the buffering mechanism  ... 

Service Oriented Device Integration - An Analysis of SOA Design Patterns

Christian Mauro, Jan Marco Leimeister, Helmut Krcmar
2010 2010 43rd Hawaii International Conference on System Sciences  
It is based on the encapsulation of devices as services, and therefore on design principles of service oriented architectures (SOA).  ...  Service oriented device architecture (SODA) is a promising approach for overcoming interoperability issues and especially for extending the IT support of business processes to devices.  ...  For devices, the physical aspect is essential. In contrast to software systems, the embedded software (but not the hardware) is a means to an end.  ...

J. Madhusudanan, S. Geetha, V. Prasanna Venkatesan, U. Vignesh, P. Iyappan
2018 Mobile Information Systems  
In this paper, a survey on the various hybrid aspects of the different context-aware middleware has been done. This middleware is classified based on service, context, and device aspects.  ...  The pervasive devices act based on the context of the situation, that is, they do their actions according to the environment of the application.  ...  Device aspects act as a logical device to share information between context aspects and physical devices.  ...

Multi-dynamics adaptations using cascaded aspect of assembly

Nicolas Ferry, Stéphane Lavirotte, Jean-Yves Tigli, Gaëtan Rey, Michel Riveill
2010 Proceedings of the 9th International Workshop on Adaptive and Reflective Middleware - ARM '10  
To handle such a dynamic, we present in this paper a mechanism for adaptation called cascaded aspects of assembly (AA).  ...  They have to be able to handle both dynamics: the dynamic of the environment and of the application. But, at least, they must consider the dynamic of the underlying software infrastructure.  ...  PHYSICAL DYNAMIC AND ADAPTATION USING CASCADED AA Aspects of Assembly (AA) [4] are based on the AOP model to define adaptation schemas and on a weaving process with logical merging.  ...
