Empirical evaluation for finger input properties in multi-touch interaction
Authors: Feng Wang, Xiangshi Ren
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

Current multi-touch interaction techniques typically only use the x-y coordinates of the human finger's contact with the screen. However, when fingers contact a touch-sensitive surface, they usually approach at an angle and cover a relatively large 2D area instead of a precise single point. In this paper, a Frustrated Total Internal Reflection (FTIR) based multi-touch device is used to collect the finger imprint data. We designed a series of experiments to explore human finger input properties and identified several useful properties such as contact area, contact shape and contact orientation which can be exploited to improve the performance of multi-touch selecting and pointing tasks. Based on the experimental results, we discuss some implications for the design of human finger input interfaces and propose several design prototypes which incorporate these implications. A set of raw data and several concrete recommendations which are useful for the research community are also presented.
MANTHA: Agent-Based Management of Hypermedia Documents
Authors: Vito Roberto, Vincenzo Della Mea, Luca Di Gaspero, Antonello Conti
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

We present an open architecture for the authoring, publishing and archiving of hypermedia documents on the Internet. The multi-agent approach is adopted, and provides solutions to design a new software layer on the top of the Internet protocol suite. We propose an agent model with the requirements of autonomy, social ability, reactivity and pro-activeness. An agent template, \textsc{James}, has been developed using \textsc{Java} and KQML as the agent communication language. On this basis, an agency is proposed and designed according to a federated model.The architecture is domain-independent, but a prototype application has been designed in the Telepathology domain. The user is given an integrated set of services, based on a structure model of the clinical case (i.e., the document), as well as metadata representation techniques. Results of the prototype implementation are presented and discussed.
Simulation of Network Traffic Using Self-adaptation Scheme
Authors: Chia-Sheng Tsai, Sh-Bin Cheng
Venue: Proceedings of the 2009 International Conference on Computer Modeling and Simulation (2009)

As communication networking becomes vital to people's digital life. Also, various communication protocols are evolved in e-Service for e-Business models. The main push factor behind this network evolution is the real time transfer of multimedia information, such as, audio, image and video. Several protocols, such as RTP (Real Time Protocol) and RTCP (Real Time Control Protocol), are developed to facilitate the deployment of multimedia services in the Internet. However, as for the intention of deliver high quality of real time multimedia information, data transmission bandwidth becomes a major issue. Insufficient network bandwidth would also result in poor service quality. To overcome this obstacle, this thesis proposes an adaptive load balancing system that targets for intensifying overall network usage in a multi path network environment. The proposed system uses a modified RTP header field to send packets through multiple paths in an RTP session to improve e-service quality. On the sender side, a suggested load balancing algorithm is used to perform RTP packet distribution. Meanwhile, the receiver side would utilize RTCP to notify senders on packet arrival intervals. Via the communication between sender and receiver, overall network bandwidth fluctuation is thus determined. By knowing the actual available network bandwidth, sender is then able to dynamically adjust packet distribution. Therefore, a load balancing system is achieved.
Applying inherent capabilities of quantum-dot cellular automata to design: D flip-flop case study

Nowadays, quantum cellular automata (QCA) has been considered as the pioneer technology in next generation computer designs. QCA provides the computer computations at nano level using molecular components as computation units. Although the QCA technology provides smaller chip area and eliminates the spatial constraints than earlier CMOS technology, but different characteristics and design limitations of QCA architectures have led to essential attentions in replacement of traditional structures with QCA ones. Inherent information flow control, limited wire length, and consumed area are of such features and restrictions. In this paper, D flip-flop structure has been considered and we have proposed two new D flip-flop structures which employ the inherent capabilities of QCA in timing and data flow control, rather than ordinary replacement of CMOS elements with equivalent QCA ones. The introduced structures involve small number of cells in contrast to earlier proposed ones in presence of the same or even lower input to output delay. The proposed structures are simulated using the QCADesigner and the validity of them has been proved.
An office form flow model
Authors: Ivor Ladd, D. C. Tsichritzis
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

Offices are data processing systems involving complex man-machine interactions. In traditional offices, machines have played a passive role. They aid in organizing, preparing, copying, storing, transmitting, analyzing and transforming data, but operations are initiated and directed by people. Replacing machines by computer systems for word processing, phototypesetting, database management and electronic mail may increase the efficiency of the offices, but it does not change their passive role. In automated offices, computer systems will be designed to play a more active role. Many well-defined routine operations can be initiated and directed by computer systems. People can then concentrate on more challenging tasks.
Improved orthogonal array based simulated annealing for design optimization
Authors: K. Y. Chan, C. K. Kwong, X. G. Luo
Venue: Expert Systems with Applications: An International Journal (2009)

Recent research shows that simulated annealing with orthogonal array based neighbourhood functions can help in the search for a solution to a parametrical problem which is closer to an optimum when compared with conventional simulated annealing. Previous studies of simulated annealing analyzed only the main effects of variables of parametrical problems. In fact, both main effects of variables and interactions between variables should be considered, since interactions between variables exist in many parametrical problems. In this paper, an improved orthogonal array based neighbourhood function (IONF) for simulated annealing with the consideration of interaction effects between variables is described. After solving a set of parametrical benchmark function problems where interaction effects between variables exist, results of the benchmark tests show that the proposed simulated annealing algorithm with the IONF outperforms significantly both the simulated annealing algorithms with the existing orthogonal array based neighbourhood functions and the standard neighbourhood functions. Finally, the improved orthogonal array based simulated annealing was applied on the optimization of emulsified dynamite packing-machine design by which the applicability of the algorithm in real world problems can be evaluated and its effectiveness can be further validated.
Data-centric support of a smart walker in a ubiquitous-computing environment
Authors: Hao Chen, James P. Black, Omar Zia Khan, Kamran Jamshaid
Venue: Proceedings of the 2nd International Workshop on Systems and Networking Support for Health Care and Assisted Living Environments (2008)

As our population ages, many researchers have investigated how assistive devices may be used to prolong independent living, thus reducing health-care costs. Some have suggested augmenting walkers (also called rollators) with sensors and actuators to assist elderly users. Such systems may also collect usage behavior and make it available to medical professionals for diagnosis or additional research. Ubiquitous computing provides an opportunity to embed computing and networking technologies in our everyday lives. It is natural to incorporate smart walkers into such environments. Some uses of a walker, such as environment customization and cognitive monitoring, also depend on a smart environment. Existing intelligent walkers usually aim at facilitating user mobility and focus on control. We propose that to support a smart walker in a ubiquitous-computing environment, the system should also focus on data, i.e., it should facilitate data collection, aggregation, and dissemination between the walker and the system. This paper describes a smart walker, and discusses how to incorporate it into a ubiquitous-computing environment using a data-centric approach with Jabber technologies. It also argues that Jabber-based middleware is suitable for general ubiquitous computing. Some applications show how the walker may be used with the middleware support.

Venue: Proceedings of the 2008 International Conference on Advanced Infocomm Technology (2008)

For the first time a distributed Raman temperature sensing system based on single-mode (SM) fiber is proposed in this paper to achieve long distance sensing. The schematic of the measure system has been described. Especially we have discussed the design process of optical splitting module. With the analysis of the whole system we present the reason of use EDFA in the design. We have shown that with 1550nm probe pulse laser being amplified to approximate 300mW, 1465nm Anti-Stokes light and 1665nm Stokes light can achieve several tens of nW and several hundreds of nW respectively.
Increasing the accuracy of neural network classification using refined training data
Authors: Taskin Kavzoglu
Venue: Environmental Modelling Software (2009)

Image classification is a complex process affected by some uncertainties and decisions made by the researchers. The accuracy achieved by a supervised classification is largely dependent upon the training data provided by the analyst. The use of representative training data sets is of significant importance for the performance of all classification methods. However, this issue is more important for neural network classifiers since they take each sample into consideration in the training stage. The representativeness is related to the size and quality of the training data that are highly important in assessing the accuracy of the thematic maps derived from remotely sensed data. Quality analysis of training data helps to identify outlier and mixed pixels that can undermine the reliability and accuracy of a classification resulting from an incorrect class boundary definition. Training data selection can be thought of as an iterative process conducted to form a representative data set after some refinements. Unfortunately, in many applications the quality of the training data is not questioned, and the data set is directly employed in the training stage. In order to increase the representativeness of the training data, a two-stage approach is presented, and performance tests are conducted for a selected region. Multi-layer perceptron model trained with backpropagation learning algorithm is employed to classify major land cover/land use classes present in the study area, the city of Trabzon in Turkey. Results show that the use of representative training data can help the classifier to produce more accurate and reliable results. An improvement of several percent in classification accuracy can make significant effect on the quality of the classified image. Results also confirm the value of visualization tools for the assessment of training pixels through decision boundary analysis.
Virtual reality training applications for the mining industry
Authors: Etienne van Wyk, Ruth de Villiers
Venue: Proceedings of the 6th International Conference on Computer Graphics, Virtual Reality, Visualisation and Interaction in Africa (2009)

Virtual reality is a rapidly growing technology which utilises the ever-increasing power of computers to simulate real-world and imaginary environments and situations with a high degree of realism and interactiveness. Safety in the South African mining industry is a vital issue. On average, one worker dies every working day, and about 16 are injured in mine-related accidents. Inadequate or insufficient training is often cited as a root cause for many mining fatalities. However, training outside the direct working environment provides only limited real-life opportunities and may fail to make a significant impact within the tense working environment itself. Virtual reality-based training tools can, by contrast, provide simulated exposure to real-world working conditions without the associated risks. This paper discusses contextual requirements and constraints for virtual reality application development, applied to safety training in mines. The results of the contextual analysis were applied to the design and development of several prototypes of VR training systems. The paper also reports on how realism can be enhanced in simulation training systems.
Research in Interactive Design: Volume 2
Authors: Xavier Fischer, Daniel Coutellier
Venue:  (2007)

Research in Interactive Design Vol. 2 provides an overview of a wide range of original research and engineering activities related to high-realistic multi-sensorial virtual prototyping dedicated to the improvement of industrial innovation. It is time for usual design and manufacturing support systems to change. Innovation requires industry to have new techniques that enable the rapid emergence of creative ideas, the development of low cost solutions, and the creation of technical consensus immediately to market and economic requirements. Virtuality should be used as early as possible in the industrial process permitting experts to rapidly explore solution spaces,to accurately study draft solutions in their future environment in a high-realistic way and to assess sketch product efficiency with futur product end-users. Interactive methods, tools and processes respond to these expectations. Interactive design and manufacturing covers a wide spectrum of multidisciplinary research largely represented in this book where you will find in-depth details related to: reduced modelling techniques: a new approach to extended and adaptive behavioural simulation development, embedded mechatronic instruments: a new approach multi-sensorial simulation implementation, interactive decision making in innovation: a new socio-technical analysis and process. In this book,both researchers and industrialists will discover the most recent interactive design techniques, and are certain to walk away with new understanding of important concepts.
Malleable iterative MPI applications
Authors: K. El Maghraoui, Travis J. Desell, Boleslaw K. Szymanski, Carlos A. Varela
Venue: Concurrency and Computation: Practice Experience (2009)

Malleability enables a parallel application's execution system to split or merge processes modifying granularity. While process migration is widely used to adapt applications to dynamic execution environments, it is limited by the granularity of the application's processes. Malleability empowers process migration by allowing the application's processes to expand or shrink following the availability of resources. We have implemented malleability as an extension to the process checkpointing and migration (PCM) library, a user-level library for iterative message passing interface (MPI) applications. PCM is integrated with the Internet Operating System, a framework for middleware-driven dynamic application reconfiguration. Our approach requires minimal code modifications and enables transparent middleware-triggered reconfiguration. Experimental results using a two-dimensional data parallel program that has a regular communication structure demonstrate the usefulness of malleability. Copyright &copy; 2008 John Wiley & Sons, Ltd.
Controller for a flexible disk
Authors: Ronald G. Harris, James E. Sustman, John F. McDonald
Venue: Proceedings of the May 6-10, 1974, national computer conference and exposition (1974)

In late 1971 several manufacturers of mass recording media began to announce initial specifications for a class of simple low-cost magnetic disks based on the IBM flexible disk initial microprogram system loader. These disks were marketed for data logging and other applications where repeated read-write activity was minimal. Their extreme low cost made it possible to integrate them into inexpensive hardware configurations as a substitute for conventional disk drives. The Memorex 651 has characteristics that are typical of the available Floppy Disk drives and is selected here as the device to be interfaced.
Efficiently tracing clusters over high-dimensional on-line data streams
Authors: Jae Woo Lee, Nam Hun Park, Won Suk Lee
Venue: Data Knowledge Engineering (2009)

A good clustering method should provide flexible scalability on the number of dimensions as well as the size of a data set. This paper proposes a method of efficiently tracing the clusters of a high-dimensional on-line data stream. While tracing the one-dimensional clusters of each dimension independently, a technique which is similar to frequent itemset mining is employed to find the set of multi-dimensional clusters. By finding a frequently co-occurred set of one-dimensional clusters, it is possible to trace a multi-dimensional rectangular space whose range is defined by the one-dimensional clusters collectively. In order to trace such candidates over a multi-dimensional online data stream, a cluster-statistics tree (CS-Tree) is proposed in this paper. A k-depth node(k=
Exploring Adolescent Peer Relationships Online and Offline: An Empirical and Social Network Analysis
Authors: Mingxin Zhang
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 03 (2009)

The study explores adolescents' online and offline peer social networks with the application of Social Network Analysis approach. Data shows that the two social networks are significantly different in terms of ego-network size, ties, density and centrality, while the expected association between adolescents' peer social network with social support is marginally supported. Data also shows that loneliness does not correlate with any of adolescent's social network basic indicators. Implications of the study are discussed.
Structural characterizations of schema-mapping languages
Authors: Balder ten Cate, Phokion G. Kolaitis
Venue: Proceedings of the 12th International Conference on Database Theory (2009)

Schema mappings are declarative specifications that describe the relationship between two database schemas. In recent years, there has been an extensive study of schema mappings and of their applications to several different data inter-operability tasks, including applications to data exchange and data integration. Schema mappings are expressed in some logical formalism that is typically a fragment of first-order logic or a fragment of second-order logic. These fragments are chosen because they possess certain desirable structural properties, such as existence of universal solutions or closure under target homomorphisms. In this paper, we turn the tables and focus on the following question: can we characterize the various schema-mapping languages in terms of structural properties possessed by the schema mappings specified in these languages? We obtain a number of characterizations of schema mappings specified by source-to-target (s-t) dependencies, including characterizations of schema mappings specified by LAV (local-as-view) s-t tgds, schema mappings specified by full s-t tgds, and schema mappings specified by arbitrary s-t tgds. These results shed light on schema-mapping languages from a new perspective and, more importantly, demarcate the properties of schema mappings that can be used to reason about them in data inter-operability applications.
Model-based test cases synthesis using UML interaction diagrams
Authors: Ashalatha Nayak, Debasis Samanta
Venue: ACM SIGSOFT Software Engineering Notes (2009)

UML 2.0 interaction diagrams model interactions in complex systems by means of operation fragments and a systematic testing approach is required for the identification and selection of test cases. The major problem for test cases synthesis from such an interaction diagram is to arrive at a comprehensive system behavior in the presence of multiple, nested fragments. In this regard, our approach is towards systematic interpretation of flow of controls as well as their subsequent usage in the test case synthesis. We also simplify the proposed flow of controls on the basis of control primitives resulting from UML 2.0 fragments and bring it to a testable form known as intermediate testable model (ITM), which is suitable for deriving system level test cases.
A distributed database design for a communications network control system
Authors: S. C. Lo, S. L. Kota, M. H. Aronson
Venue: Proceedings of the May 16-19, 1983, national computer conference (1983)

A three-level distributed database concept is proposed to meet the high performance requirements of an integrated communications network control system. The three levels are source, user, and control. By using fully replicated subject databases in the source level, one regional operations center can serve as a backup for any other center. The applications database in each user level is a subset of the subject databases residing in the source level. Hence, the user level is localized and can respond to near real-time network control requirements. The control level coordinates updates to the distributed database copies. Interactions among the three levels are discussed and four operational stages are considered: initialization, continuous update, global synchronization, and data recovery. A broader usage of the data dictionary is proposed. Simplification of the replicated database design in terms of isolation of global and local data and some implementation considerations are provided.

Time-of-flight cameras with multiple distributed illumination units
Authors: O. Lottner, W. Weihs, K. Hartmann
Venue: Proceedings of the 8th conference on Signal processing, computational geometry and artificial vision (2008)

In this paper, the simultaneous operation of multiple distributed illumination units for time-of-flight (TOF) cameras is addressed. On the one hand, multiple illumination units can be used independently of each other by several means (spatial, temporal, wavelength and modulation division). On the other hand, constructive interference of a number of illumination units can be used to increase the modulation contrast, to decrease the necessary integration time and to increase the phase data reliability.
