A Comparison Study of Different Optimizing Criteria and Confounding Patterns For Multi-Level Binary Replacement and Other Designs Used in Computer Experiments

We have constructed four different types of designs for computer experiments. The design types are based on latin hypercube sampling (LHS), orthogonal arrays (OA), ran- dom sampling and the recently proposed multi-level binary replacement (MBR) design. For each type of design we have attempted to find the best possible design out of a certain number of constructed designs using three different optimizing criteria: the alias sum of square criterion (ASSC), the L-criterion and a modified A-criterion. The chosen design has then been tested by fitting an approximate model and calculating maximum error (MAX) and root mean squared error (RMSE) values. We observed that out of the three criteria applied the ASSC performed the best. In addition to comparing criteria for optimizing the design choice, we have also constructed non-optimized designs for comparing the different design types and the different ways of constructing MBR designs. In this setting we observed that OA designs performed well in general, whereas the MBR designs performed well when restricted to a small number of factors.

Classical and quantum analysis of quasiresonance in grazing atom-surface collisions

Quasiresonance is a general effect that may arise from the coupling between approximately resonant degrees of freedom in a system perturbed by some transient interaction. In a process induced by a slowly switching on and off of the coupling interaction, quasiresonance is characterized by the existence of significant ranges of initial states in the perturbed system over which some very specific and efficient transfer of energy between the approximately resonant degrees of freedom occurs. This work presents a classical and quantum analysis of quasiresonant processes in grazing incident angle atom-surface collisions. The momentum transfer between the normal components to an index direction is investigated. For fast atoms with grazing angle of incidence there is an interval of azimuthal angles around the index directions, the quasiresonance region, in which the energy transfer can be very efficient. This effect is reflected in quantum diffraction patterns with large nonspecular peaks, associated with the parallel to the surface and normal to the index direction momentum component. We demonstrate the essentially classical underlying mechanism for the persistence of a pattern of diffraction peak intensities for incidence close to an index direction. The analysis also shows that the size of the quasiresonance region is approximately equalmore » to the spectral width of the diffraction pattern. « less
InnovaTouch: a multi-touch framework to support gesture recognition for innovation activities

We introduce InnovaTouch, a framework designed to provide gesture recognition services for applications that utilize multi-touch interactive surfaces. InnovaTouch defines and recognizes a set of gestures for general actions such as selecting, moving, rotating and resizing objects on interactive surfaces, as well as more specific multi-touch gestures intended to serve as accelerators for common actions in innovation settings. These accelerators include gestures for editing or deleting existing objects, extracting and modifying object properties, creating links among workspaces, as well as undoing and redoing recent actions.
The Optimizability-Fidelty Trade-Off in Image Analysis

Image analysis problems (e.g. segmentation and registration) are typically formulated in an optimization framework (energy-minimization). In this work, I present two important recurring questions: What to optimize and how to optimize and expose the resulting tradeoffs between the fidelity (of the domain and range) of the objective function and its optimizability. All slides as a video are available from: http://summit.sfu. ca/item/10897 Direct link to the video: http://summit.sfu. ca/system/files/iritems1/10897/hamarneh-optimizability-fidelity-space-tradeoff.mov
Intelligent data management for real-time spacecraft monitoring

Real-time AI systems have begun to address the challenge of restructuring problem solving to meet real-time constraints by making key trade-offs that pursue less than optimal strategies with minimal impact on system goals. Several approaches for adapting to dynamic changes in system operating conditions are known. However, simultaneously adapting system decision criteria in a principled way has been difficult. Towards this end, a general technique for dynamically making such trade-offs using a combination of decision theory and domain knowledge has been developed. Multi-attribute utility theory (MAUT), a decision theoretic approach for making one-time decisions is discussed and dynamic trade-off evaluation is described as a knowledge-based extension of MAUT that is suitable for highly dynamic real-time environments, and provides an example of dynamic trade-off evaluation applied to a specific data management trade-off in a real-world spacecraft monitoring application.
Making learners aware of the prosody of a foreign language

The work presented here aims at making learners aware of the prosody of a foreign language. Learners are not conscious of the prosody of the foreign language and use prosodic schemes of their mother language instead. To help them, speech signal analysis tools are provided. Then the realization of a learner is com-pared to a model. This comparison enables us to set up several strategies to make the learning easier. In particular, the visualization of the prosodic cues of the two realizations, the modifications of the prosodic cues of the learner and the localization of the deviations help the learners to assimilate the prosody of the foreign language. To evaluate automatically the deviations, two applications were developed: - the automatic localization of the word lexical accent accompanied by a diagnosis on its realization; - an automatic auditory correction of the learners' realization. This work exploits a corpus especially designed by English teachers to fit the needs of learners on each domain of prosody.

On the validity of the Arrhenius picture in two-dimensional submonolayer growth

For surface-mediated processes, such as on-surface synthesis, epitaxial growth and heterogeneous catalysis, a constant slope in the Arrhenius diagram of the corresponding rate of interest against inverse temperature, $\log R$ {\it vs} $1/k_B T$, is traditionally interpreted as the existence of a bottleneck elementary reaction (or rate-determining step), whereby the constant slope (or apparent activation energy, $E_{app}^{R}$) reflects the value of the energy barrier for that reaction. Here, we show that a constant value of $E_{app}^{R}$ can be obtained even if control shifts from one elementary reaction to another. In fact, we show that $E_{app}^{R}$ is a weighted average and the leading elementary reaction will change with temperature while the actual energy contribution for every elementary reaction will contain, in addition to the traditional energy barrier, a configurational term directly related to the number of local configurations where that reaction can be performed. For this purpose, we consider kinetic Monte Carlo simulations of two-dimensional submonolayer growth at constant deposition flux, where the rate of interest is the tracer diffusivity. In particular, we focus on the study of the morphology, island density and diffusivity by including a large variety of single-atom, multi-atom and complete-island diffusion events for two specific metallic heteroepitaxial systems, namely, Cu on Ni(111) and Ni on Cu(111), as a function of coverage and temperature.
Improved Differential Fault Analysis on Block Cipher PRESENT-80/128

A differential fault analysis(DFA) is one of the most important side channel attacks on block ciphers. Most block ciphers, such as DES, AES, ARIA, SEED and so on. , have been analysed by this attack. PRESENT is a 64-bit block cipher with 80/128-bit secret keys and has a 31-round SP-network. So far, several DFAs on PRESENT have been proposed. These attacks recovered 80, 128-bit secret keys of PRESENT with 8~64 fault injections. respectively. In this paper, we propose an improved DFA on PRESENT-80/128. Our attack can reduce the complexity of exhaustive search of PRESENT-80(resp. 128) to on average 1.7(resp. ) with 2(resp. 3) fault injections, From these results, our attack results are superior to known DFAs on PRESENT.
Managing Elective and Non-elective Case Assignments for an Operating Room Suite

The success of operating room management depends on all levels of decision making, from strategic to tactical and operational decisions. One key decision in systems with block booking is to assign sufficient amount of block time to surgeons and surgery groups. While the typical method of block assignment identifies the share of surgery groups from OR times based on average of past usage, this method does not count for the difference between cost of under and overtime. One of the goals of this research is to develop a decision framework for block assignment. This work is presented in chapter two. In this part first, I provide with the linear program that finds the length of block assigned to surgery groups while considering the amount of past undertime and overtime. This model then simplified through valid assumptions. In addition, a case study is conducted to support the usefulness of the method. The results show that 12 months of past data is sufficient amount of data to use in this method. Also, this method of block allocation out performs the existing time series method in literature.
Multi-Domain Sketch Recognition

In this paper, we describe a new framework for multi-domain sketch recognition which is being developed by the Design Rationale Group at the MIT AI laboratory. The framework uses a blackboard architecture for recognition in which the knowledge sources are a combination of domain-independent and domain-specific recognizers. Domain-specific recognizers are automatically generated from the domain description which is written using the domain description language syntax. Domain descriptions can be automatically generated by a system that learns shape descriptions from a drawn example.
Discovering Faithful `Wickelfeature' Representations in a Connectionist Network

Abstract : A challenging problem for connectionist models is the representation of varying-length sequences (e.g., the sequence of phonemes that compose a word). One representation that has been proposed involves encoding each sequence element with respect to its local context; this is known as a "Wickelfeature" representation. Handcrafted Wickelfeature representations suffer from a number of limitations, as pointed out by Pinker and Prince (1988). However, these limitations can be avoided if the representation is constructed with a priori knowledge of the set of possible sequences. This paper proposes a specialized connectionist network architecture and learning algorithm for the discovery of faithful Wickelfeature representations -- ones that do not lose critical information about the sequence to be encoded. The architecture is applied to a simplified version of Rumelhart and MeClelland's (1986) verb past-tense model.
A tutorial on using the rminer R package for data mining tasks

This tutorial explores the rminer package of the R statistical tool. Following a learn by example approach, several code recipes are presented and the obtained results analyzed. The goal is to demonstrate the package capabilities for executing classification and regression data mining tasks, including in particular three CRISP-DM stages: data preparation, modeling and evaluation. The particular case of time series forecasting is also addressed.
A Mathematical Cross-Correlation for Time-Alignment of Cockpit Voice Recorder and Flight Data Recorder Data

A new method is described for performing timing correlations between flight data recorder (FDR) and cockpit voice recorder (CVR) information. This method involves the use of the cross-correlation function to search the typically larger FDR data file for a best match to the event pattern present in the CVR data file. The results of this search give a first-order estimate of the time differential between identical events as recorded on both units. A simple curve fit may then be employed to obtain a general conversion from time as represented in the CVR and time as represented in the FDR.
El estado de la cuestión como género de formación en la carrera de Historia

The state of the art is one of the academic genres that the students of History at the University of Buenos Aires must write to pass some of the subjects in the degree. However, no attention has been paid to the specific characteristics of the state of the art as a student genre. Although the state of the art is not an independent genre for professional writers, in the History degree such kind of text is used as a genre in itself as it is not included in another one. In this paper I aim to analyze the characteristics of the state of the art as an independent and student genre and to study its disciplinary goals through an empirical, contrastive and qualitative analysis of a corpus of eight student’s texts which are labeled as “states of the art”. This analysis can shed some light on student genres research, especially for History writing at university.
Comparing Adaptive Control of Thought-Rational (ACT-R) Baseline Activation Terms for Implementation in the Symbolic and Subsymbolic Robotic Intelligence Control System (SS-RICS)

Abstract : The U.S. Army Research Laboratory is developing the Symbolic and Subsymbolic Robotic Intelligence Control System (SS-RICS) as a robotic control system based on human cognition. It has, as part of its intelligence, a production system similar to that of Adaptive Control of Thought Rational (ACT-R). One feature of the ACT-R system is that chunks of information about the surrounding environment have recorded activation values, which increase when the system turns its attention toward them and decrease in the absence of attention. This feature can be beneficial in keeping recently used information readily available to attention. It can also be detrimental when a feedback loop develops, with a chunk being selected for attention because it has the highest activation and then increasing its activation value as a result. This report explores the behavior of the baseline activation equation with different parameter settings, and over different patterns of selection, in order to provide SS-RICS researchers with information for selecting appropriate parameters. It also makes recommendations as to how the equations might be modified to eliminate such feedback loops.
A Preliminary Study on BN-Robots' Dynamics

Boolean network robotics concerns the use of Boolean networks as robot programs. In this brief contribution, we outline preliminary results on the analysis of the dynamics of BN-robots trained to accomplish a composite task. We find that the successful performing robots, which show the capability of robustly attaining the learned behaviours while adapting to new tasks to perform, are characterised by both number of fixed points and complexity higher than those of unsuccessful ones. These results are in accordance with the conjecture that systems able to balance robustness and evolvability work at the border between order and chaos and may suggest improvements to the automatic design of robot programs.
Visualizing Multiple Two-Dimensional Fields of Data in a Single Image:

With advancemens in scientific measurement instruments and simulation tech- niques come increasingly complex and in many cases multivariate data. The devel- opment and improvement of techniques that are able to convey as much information as possible from this data to scientists, doctors, and other potential users is an important research topic in the field of scientific visualization. This thesis contributes a new automated approach to the visualization of multiple two-dimensional, spatial data fields in a single image. We introduce a new generative formal grammar called texture grammar that combines implementations of existing visualization techniques and image compositing techniques to automatically produce visualizations, depending on the input fields. The image compositing techniques are perceptually motivated, and we evaluated their effectiveness with a user study. The resulting visualizations capture important characteristics of all input fields, as well as relations between the fields. An added benefit of this method is the reduction of user interaction, since a larger amount of data can be perceived at once.
Implementação de um controle digital para o compensador regenerativo de potência ativa

Nowadays, electric power systems are expected to work closer to their operating limits. Power electronics based controllers, such as voltage sourced converters, are increasingly present in power systems. Electronic devices are often used to energy controlling and conditioning. The use of voltage sourced converters, associated to high-density storage elements, is the basic configuration of a Regenerative Active Power Compensator. Regenerative Active Power Compensator is a concept which proposes the energy storage as a possibility for revaluation of electrical energy cost with demand contracts. This concept is based on storing energy surplus during off peak periods, when the energy cost is cheaper, and injecting it back to the system during the overpriced peak periods. This procedure allows a better equalization of energy consumption and a reduction in electric power demand contracts. Therefore, using regenerative active power compensation, the consumption is dislocated from peak periods, resulting in a reduction of energy costs for the consumer. This concept is especially attractive for countries that use hour-seasonal fees police, as in the Brazilian case. This work proposes a three-phase model simulation with digital signal processor controller to investigate the active power flow control between the power system and the compensator, using a proportional-integral-derivative control strategy. The control signals are generate using the Texas Instruments DSP TMS320F2808, witch is embedded into the eZdsp F2808 didactic module, from Spectrum Digital.
Low Energy AES Hardware for Microcontroller

Cryptographic algorithms, like the Advanced Encryption Standard, are frequently used in todays electronic appliances. Battery operated devices are increasingly popular, creating a demand for low energy solutions. As a microcontroller is incorporated in virtually all electronic appliances, the main objective in this thesis is to evaluate possible hardware implementations of AES and implement a solution optimized for low energy consumption, suited for incorporation in a microcontroller. A good cost/performance balance is also a design goal. An existing solution based on a 32 bit architecture with support for 128 bit keys was chosen as a basis and altered in order to lower area and energy consumption. The alterations yielded a 13.6% area reduction as well as 14.2% and 3.9% reduction in energy consumption in encryption and decryption mode, respectively. In addition to alterations in the datapath, low energy techniques like clock gating and numerical strength reduction has been applied in order to further lower the energy consumption. The proposed architecture was also extended in order to accommodate 256 bit keys. Although this increased the area by 9.2%, the power consumption was still reduced by 7.6% and 1.3% in en- and decryption, compared to the architecture chosen as basis. As AES is an algorithm which easily can be parallelized, a high throughput solution utilizing a 128 bit datapath was implemented. This AES module is able to process 372.4 Mbps at an operating frequency of 32 Mhz and is based on the same architecture as the 32 bit datapath solution. In addition, this implementation yielded excellent energy per encryption figures, 24.5% lower than the 32 bit solution. The alternative to performing AES in a dedicated hardware module is to perform it using software. In order to have a basis for comparison, a software solution optimized for 32 bit architectures was implemented. Simulations show that the energy consumption attained when performing AES in the proposed hardware module is approximately 2.3% of what a software solution would use. In addition, the throughput is increased by a factor of 25. The architecture proposed in this thesis combines relatively high throughput with modest demands to area and low energy per encryption.
