Chameleon art: a platform for interactive art production
Authors: M. C. Lim, T. Tan, A. Hutchison, L. Li, M. Lazarescu
Venue: Proceedings of the 2nd international conference on Digital interactive media in entertainment and arts (2007)

Chameleon Art is a script-based system that is used to easily produce Interactive Art. Digital media enables interactivity, non-linearity and mutability of media such as text, images, video and sound. It is this aspect of digital media that makes it very compelling, gaining and holding the attention of the audience. Computer/video games and the Internet phenomenon are obvious examples of this potential. The interactive component of the system comes mainly from the input plug-in system which are in turn linked to live sensor inputs. Specific examples of data that might be gathered include - face detection and recognition, personal tag capture, motion behaviour of individual or groups, sensor network feeds, ambient sound level, temperature, and other electronic form of data. Features of these data can then be used to transform an aesthetically pleasing and dynamic art form, manifested as projected images and/or audio that changes in real time. Chameleon Art is not meant to be a specific, custom created interactive artwork. It's innovation lies in the visual script-based design that solves the huge technical obstacles involved in processing environmental data, and allows these data sources to be turned into unique interactive artwork by artists/designers. In addition, the system is supported by a simple "flow chart and icons"-based graphical interface for the manipulation of this data and its transformation into a visual experience by an artist. Thus, the cost and time to produce interactive works are greatly reduced, and the aesthetic value of the works that can be produced is greatly increased. One of the primary objectives of this project is to develop features that are extensible and scalable across the different levels of the system. This has been achieved via the deployment of modified plug-in architecture. Through the use of plug-ins, new features and functionalities can be added without having to modify the core system. This also allows third-party developers to create new content for the system. The architecture consists of three types of plug-in systems: display plug-ins, input plug-ins, and scripts. The prototype demonstration of Chameleon Art will include showing the functionalities of the three sub modules (e.g. input plug-ins, graphics plug-ins and the scripting interface). We will use the webcam as the input device from which we use OpenCV (http://www.intel.com/technology/computing/opencv/) and some of our in house Computer Vision tools to perform scene understanding (e.g. face detection, gesture recognition, and etc). We will demonstrate how the script-based interface can be use to selectively connect the input features to all the possible graphics rendering techniques. We will also package a complete Art system making use of these functions.
Profitless delays for permanence in a pure-delayed nonautonomous Lotka-Volterra competitive system with infinite delays and discrete delays
Authors: Xinzhu Meng, Huidong Cheng, Lansun Chen
Venue: Proceedings of the Eighth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing - Volume 01 (2007)

This paper studies a pure-delayed nonautonomous Lotka-Volterra competitive system with infinite delays and discrete delays. Sufficient conditions are obtained for the permanence of the system. The permanence of the system is dependent of time delays, that is, they are "profitless" delays because they have effect on the permanence of the system.
Toward a Hardware Real Time SIMO Channel Emulator
Authors: Paul Chatellier, Patrick Tortelier, and Emmanuel Boutillon
Venue: Proceedings of the Third IEEE International Conference on Wireless and Mobile Computing, Networking and Communications (2007)

the most time consuming element of a wireless system simulation, especially when dealing with multiple antennas. Any method that reduces this simulation time is thus welcomed. As an interesting solution, real time simulation using an hardware platform is the most commonly used, especially with the help of high level synthesis tools which will shrink the gap between system level simulations, written in C or C++, and hardware level. In this paper, we extend an existing model of Rayleigh faders with interesting complexity to a SIMO case. We show, analytically and by simulation, that the spatial correlation of our simplified channel model are in accordance with the expected one. For a more realistic model, we take into account the existence of angle spread scenarii.
Heartbeat based fault diagnosis for mobile ad-hoc network
Authors: Pabitra Mohan Khilar, Sudipta Mahapatra
Venue: Proceedings of the third conference on IASTED International Conference: Advances in Computer Science and Technology (2007)

The problem of identifying faulty mobiles in ad-hoc networks is considered. Current diagnostic models were designed for wired network. For the suitability to multi-hop ad-hoc network this paper considers the problem of achieving distributed diagnosis in arbitrary topology networks in dynamic fault environments. In order to diagnose the state of the wireless adhoc network, diagnostic tasks are assigned to all mobiles and the outcomes of these tasks are compared. We describe a new distributed self-diagnosis protocol for wireless adhoc networks that is able to identify crash and value faults in a finite amount of time. Heartbeat based mechanisms have been used to detect the failure and recovery events. It is assumed that the mobiles can change their states at any time provided the network remains connected and the frequency with which events can occur on a node has an upper limit. This is characterized and quantified by deriving a minimum state holding time. The algorithm DDMAN is compared with a similar algorithm FHB given in paper [5] and is shown to produce shorter average diagnostic latency with comparable message complexity under a more realistic fault model.
Montgomery Multiplication with Redundancy Check
Authors: Khanh Nguyen, Michael Tunstall
Venue: Proceedings of the Workshop on Fault Diagnosis and Tolerance in Cryptography (2007)

This paper presents a method of adding redundant code to the Montgomery multiplication algorithm, to ensure that a fault attack during its calculation can be detected. This involves having checksums on the input variables that are then used to calculate a valid checksum for the output variable, in a similar manner to that proposed by Walter. However, it is shown that the proposed method is more secure than the previous work, as all the variables required to calculate Montgomery multiplication are protected.

Authors: Christian Morillas, Samuel Romero, Antonio Martínez, Francisco Pelayo, Leonardo Reyneri, Markus Bongard, Eduardo Fernández
Venue: Neurocomputing (2007)

The cooperation between neuroscience and biomedical engineering gave rise to a recent, but growing research field, known as neuroengineering. We follow its principles to have a system providing basic descriptions of the visual world to the brain's cortex. We describe a set of software and hardware tools to interface with neural tissue, in order to transmit visual information encoded into a bioinspired neural-like form. The set is composed of a retina-like encoder, and a platform to optimize electrical stimulation parameters for a multi-electrode implant. The main objective is to progress towards a functional visual neuroprosthesis for the blind.
On an Ordering of Walsh Functions
Authors: H. Butin
Venue: IEEE Transactions on Computers (1978)

In addition to the automorphism between the sequency and the Gray-code-of-sequency ordering for Walsh functions there is also one for Kacsmarz ordering. This is shown by using a matrix definition suggested by K. W. Henderson some years ago [4].
Subtraction by Minuend Complementation
Authors: G. G. Langdon
Venue: IEEE Transactions on Computers (1969)

In performing the operation of subtraction in additive systems, a popular practice is to complement the subtrahend and add. A second method of performing subtraction, which seems to have been overlooked, is to complement the minuend, add it to the subtrahend, and complement the result. In many cases, this second method is more awkward; however, in two instances it seems to be worthy of consideration. The first instance, surprisingly enough, concerns BCD systems, where minuend complementation can compare favorably with more conventional methods of BCD subtraction. The second instance concerns negative radix numbers where the technique of minuend complementation seems to offer definite advantages.
Optimum fuzzy sliding mode semi-active control of structures subjected to earthquakes
Authors: A. I. Dounis, R. E. King
Venue: Journal of Intelligent Fuzzy Systems: Applications in Engineering and Technology (2003)

This paper presents a design procedure for a class of optimized semi-active controllers for structures subjected to seismic activity. The structure is controlled through a single force applied to a controllable electromagnetic damper placed on the first storey of the structure. The restraining control force is computed in real-time using a fuzzy sliding mode control algorithm. The parameters of the controller are optimized using a global stochastic search based on the Metropolis simulated annealing algorithm. The resultant disturbance mitigation of the proposed controller has been verified through extensive simulation of a multi-storey structure using realistic earthquake data. In this paper a new form of semi-active controller is proposed. The proposed fuzzy sliding mode controller possesses three parameters whose optimum values are computed using simulated annealing. Through simulation of a six storey structure subjected to known earthquake tremors it is shown that the performance of the proposed controller is superior to other semi-active control scheme that have been proposed thus far.
An Improved Migration Strategy of Mobile Agent
Authors: Jian-pei Zhang, Jun Ma, Jing Yang, Li-li Cheng
Venue: Proceedings of the Fourth International Conference on Fuzzy Systems and Knowledge Discovery - Volume 01 (2007)

Mobile agent migrates to several hosts for completing its task. Migration strategy is responsible for planning out an optimal migration path, which ensures mobile agent to accomplish its task correctly and efficiently. In this paper, the concept of migration strategy based on support vector machine is proposed. Mobile agent with support vector machine can perceive the changes of environment, react immediately, embodying the reactivity and autonomy of agent. Compared with other migration strategies, it can obtain the optimal result with high probability. The simulation experiment on Aglet platform shows that the migration strategy is effective and available.

Venue: Proceedings of the 18th International Conference on Database and Expert Systems Applications (2007)

As part of the general growth and diversification of media in different modalities, the presence of information in the form of human speech in the world-wide body of digital content is becoming increasingly significant, in terms of both volume and value. We present a semantic-based search model for human speech corpora, stressing the search for meanings rather than words. Our framework embraces the complete recognition/retrieval cycle, from word spotting to semantic annotation, query processing, and search result presentation.
2007 Special Issue: The apical dendrite theory of consciousness
Authors: David LaBerge, Ray Kasevich
Venue: Neural Networks (2007)

The neural basis of consciousness is theorized here to be the elevated activity of the apical dendrite within a thalamocortical circuit. Both the anatomical and functional properties of these two brain structures are examined within the general context of the cortical minicolumn, which is regarded as the functional unit of the cerebral cortex. Two main circuits of the minicolumn are described: the axis circuit, which sustains activity for extended durations and produces our sensory impressions, and the shell circuit, which performs input-output processing and produces identifications, categorizations, and ideas. The apical dendrite operates within the axis circuit to stabilize neural activity, which enables conscious impressions to be steady and to be sustained over long periods of time. In an attempt to understand how the conscious aspect of subjective impressions may be related to apical dendrite activity, we examine the characteristics of the electric and magnetic fields during the movement of charges along the apical dendrite. The physical correlate of consciousness is regarded here as the relatively intense electromagnetic field that is located along the inside and the outside close to the surface of the active apical dendrite.
Automatic Decision Making in SHM Using Hidden Markov Models
Authors: Constanze Tschope, Matthias Wolff
Venue: Proceedings of the 18th International Conference on Database and Expert Systems Applications (2007)

Decision making and classification methods are very important in the field of structural health monitoring and life cycle prediction. We want to introduce an approach basing on sequence classifiers which can be used to several applications without any explicit knowledge of structures. To illustrate the concept we explain the method by means of a special example. So we can demonstrate our approach detailed, but although not too abstract.

Analyzing Software Safety
Authors: N. G. Leveson
Venue: IEEE Transactions on Software Engineering (1983)

With the increased use of software controls in critical realtime applications, a new dimension has been introduced into software reliability-the "cost" of errors. The problems of safety have become critical as these applcations have increasingly included areas where the consequences of failure are serious and may involve grave dangers to human life and property. This paper defines software safety and describes a technique called software fault tree analysis which can be used to analyze a design as to its safety. The technique has been applied to a program which controls the flight and telemetry for a University of California spacecraft. A critical failure scenario was detected by the technique which had not been revealed during substantial testing of the program. Parts of this analysis are presented as an example of the use of the technique and the results are discussed.
A Quality-Driven Algorithm for Resource Scheduling Based on Market Model on Grid
Authors: Lei Tang, Zhiyi Yang, Zhiwen Yu, Yunlan Wang
Venue: Proceedings of the 2007 International Conference on Parallel Processing Workshops (2007)

Several challenges about computational grid exist in integrating, coordinating and managing of resources and scheduling of applications, due to distributed resources at various levels. In this paper, we employ computational economy as a way to manage and allocate these distributed resources. It can help to rapidly and dynamically select resources meeting users' functional requirements and satisfying their Quality of Service (QoS), from a large number of resources. An economic scheduling system based on market model is presented. On the basis of studying QoS criteria of resource services, we formulate selection as Multiple Attribute Decision Making (MADM) problem. Then, we introduce MQoS model to evaluate resource services for selection, which consists of the MQoS vector, a decision matrix and a qualitydriven scheduling algorithm. The algorithm is classified as lexicographic and Euclidean Distance algorithm with respect to user's preference and object impact. It optimizes system performance through adjusting resource selection automatically according to previous job execution and the current system state information such as load. The results of scheduling experiments showed the superiority of quality-driven algorithm in scheduling on global grids.
On Test Data Generation of Object-Oriented Software
Authors: Andrea Arcuri, Xin Yao
Venue: Proceedings of the Testing: Academic and Industrial Conference Practice and Research Techniques - MUTATION (2007)

Nowadays, Object-Oriented (OO) languages are widely used in the development of many different kinds of applications. However, testing those applications is still very expensive and time-consuming for the software community. The automation of this task would therefore be highly desirable. Although automatic testing of procedural software has been studied in depth for many years, comparatively little work has been done about OO software. Different techniques exist. However, the most promising one is probably to model the task as a Search Problem. This paper explains why automatic testing of OO software is more difficult than procedural software. These difficulties provide strong challenges to the Natural Computation and Software Engineering communities. A brief review of the literature of the subject follows. The issues of the current State-of-Art of the field are then outlined. Finally, some open research problems are discussed.

A New Type of Proxy Ring Signature Scheme with Revocable Anonymity
Authors: Chengyu Hu, Daxing Li
Venue: Proceedings of the Eighth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing - Volume 01 (2007)

In a proxy signature scheme, a potential signer delegates his signing power to a proxy, who signs a message on behalf of the original signer. The ring signature allows a user from a set of possible signers to convince the verifier that the author of the signature belongs to the set but identity of the author is not disclosed. In some real situations, we must apply them both concurrently. In this paper, we present a new type of proxy ring signature scheme with revocable anonymity which allows the original signer to know exactly who the signer is. It plays an important role in some applications.
Exploiting STI stress for performance
Authors: Andrew B. Kahng, Puneet Sharma, Rasit O. Topaloglu
Venue: Proceedings of the 2007 IEEE/ACM international conference on Computer-aided design (2007)

Starting at the 65nm node, stress engineering to improve performance of transistors has been a major industry focus. An intrinsic stress source - shallow trench isolation - has not been fully utilized up to now for circuit performance improvement. In this paper, we present a new methodology that combines detailed placement and active-layer fill insertion to exploit STI stress for performance improvement. We perform process simulation of a production 65nm STI technology to generate mobility and delay impact models for STI stress. Based on these models, we are able to perform STI stress-aware delay analysis of critical paths using SPICE. We then present our timing-driven optimization of STI stress in standard cell designs, using detailed placement perturbation to optimize PMOS performance and active-layer fill insertion to optimize NMOS performance. We assess our optimization on small designs implemented with a 65nm production cell library and a standard synthesis, place and route flow. Our timing-driven optimization of STI stress impacts can improve clock frequency by between 7% to 11%. The frequency improvement through exploitation of STI stress comes at practically zero cost in terms of design area and wirelength.
Inhomogeneities in wall stress measured by microergometry in the heart muscle in situ

Venue: Technology and Health Care (1997)

Microergometry is a method which we have developed as a tool to measure local mesh-tension within the myocardial weave at any measuring site of both ventricles and the septum on the beating heart in situ. In a mapping procedure on pig and dog hearts, both in control conditions and in the hypertrophied state after aortic banding, local mesh-tension was measured in several areas and in up to eight depths proceeding from the epicardium to the endocardium&colon; Probe-to-fibre coupling is definitely more stable in the canine myocardium than in the porcine heart muscle, probably due to a more effective connective tissue fettering of the canine myocardial weave. The observed longitudinal gradient, with the highest tension in the base, of control dog hearts was levelled out in the hypertrophied hearts. Furthermore, in control dog hearts mesh-tension in the subepi- and subendocardial layers was higher than in the midlayers. This pronounced midlayer-hypotension was smoothed in the hypertrophied hearts. Further studies will be dedicated to the question of whether the impact of ventricular size and shape on intersegmental stress transmission is determined by the Frank-Starling mechanism alone or whether protracted remodelling processes on the level of the local fibre weave cause slow coupling alterations.
Pipelined Binary Parallel Counters Employing Latched Quaternary Logic Full Adders
Authors: K. W. Current
Venue: IEEE Transactions on Computers (1980)

Parallel counters are multiple input circuits that count the number of their inputs that are in a given state. In this correspondence, the implementation of pipelined binary parallel counters with networks of latched quaternary threshold logic full adders is described and compared with the implementation using networks of latched binary full adders. Since each signal variable in quaternary logic may assume four logical states, twice the informational content of a binary variable, an over 50 percent savings in the total number of intermediate signal variables required to implement the parallel counter results. With the new quaternary logic circuits we will employ, over 40 percent fewer transistors and resistors are necessary for the implementation of pipelined binary parallel counters. The combination of these two factors could provide significantly reduced die areas for integrated pipelined parallel counters.
A New Method for Measuring Similarity between Intuitionistic Fuzzy Sets Based on Normal Distribution Functions
Authors: Zehua Lv, Chuanbo Chen, Wenhai Li
Venue: Proceedings of the Fourth International Conference on Fuzzy Systems and Knowledge Discovery - Volume 02 (2007)

This paper puts forward a new kind of similarity measure between Intuitionistic Fuzzy Sets (IFSs) based on normal distribution functions. At first, we propose a method to express an intuitionistic fuzzy set by a series of normal distribution functions. Then, we use these normal distribution functions to calculate the degree of similarity between IFSs. The properties of the proposed similarity measure are proved and several numerical examples are taken to validate it. Compared with the existing methods, the proposed similarity measure is more reasonable and more suitable for any special situation. Moreover, by comparing the proposed similarity measure with the existing measures, our method shows that it is much more reliable than the existing measures to linguistic variables. Though having a little difficulty for calculation, the similarity measure presents a brand- new method to deal with fuzzy information.
