Development of Dynamic Profiler for Monitoring Functions in Embedded Applications

It is important to guarantee the reliability of applications for real-time systems such as avionics. Generally, a profiler, which uses the static analysis technique, is employed to analyze the performance and temporal problem regions in the embedded applications. However, the profiler based on static analysis considering source codes does not predict the executions of dynamic functions in the application but also monitors the hierarchical execution structure of functions. This paper presents a dynamic profiler to analyze the execution time of each function and to trace the hierarchical structure of function calls.
Neural networks trained with simulation data for outcome prediction in pallidotomy for Parkinson's disease

Neural networks were trained using the ALOPEX technique to predict the outcome of pallidotomy, an operation performed to alleviate Parkinson's disease. Because of the limited number of operations performed, the training procedure relied heavily on simulation data. The assumptions from which the simulation data were derived were reflected in the performance of the resultant networks; the networks nonetheless retained the flexibility to respond appropriately to unusual inputs.

A system of analyzing and synthesizing facial images

A system is presented which analyzes and synthesizes the facial images. This system is focused on analysis and synthesis of facial features. Any particular image is assumed to be a weighted sum of facial image bases. The weights represent the facial features of the particular image. A method which analyzes and synthesizes the facial images on the basis of a three-dimensional facial shape model is presented. The method is extended so that the features of parts as well as the whole of the face can be analyzed and synthesized. Moreover, a procedure is developed for orthogonalizing the image bases for optimal description. <<ETX>>
Synthesis of control circuits in folded pipelined DSP architectures

A systematic folding transformation technique to fold any arbitrary signal processing algorithm data-flow graph to a hardware data-flow architecture, for a specified folding set and specified technology constraints, is presented. The folding set specifies the processor and the time partition at which the task is executed and is typically obtained by performing scheduling and resource allocation for the algorithm data-flow graph and the specified iteration period. The constraints imposed on the hardware architecture are also assumed to be known. The technique is used to derive the control circuitry of the hardware architecture. The authors derive conditions for the validity of a specified folding set, and present approaches to generate the dedicated architecture using systematic folding of tasks to operators. They propose automatic retiming and pipelining of algorithms described by data-flow graphs for folding. The folding algorithm is applied after preprocessing the data-flow graph for automated pipelining and retiming. >
Perceptually based low bit rate video coding

The full motion video described is based on the efficient coding of three dimensional subband data. The resulting bit rates of this coder include 384 kb/s results for image sequences of medium complexity and 128 kb/s results for simpler image sequences. The image data are decomposed into spatiotemporal frequency bands and different quantization schemes are applied to each frequency band based on the characteristics of the data in that band. The lowest spatiotemporal frequency band is coded using an unbalanced tree-structured vector quantization technique where the temporal and spatial correlations are exploited in a lossless coding technique referred to as interblock noiseless coding. <<ETX>>

Over the past few years, the science of developing vaccines have had, and continue to prevent diseases. Veterinary vaccines have a major role in reducing animal suffering, protection of animal health and enhance efficient animal productivity. Ticks are considered among the most important disease transmitting vectors second to mosquitoes. Tick borne diseases affect both human and livestock animals in many tropical and subtropical areas [1,2]. Ticks transmit several viral infections, bacterial and protozoan diseases causing Encephalitis, Crimean-Congo Hemorrhagic fever, Kyasanur forest disease, Lyme disease, Rocky Mountain spotted fever, monocytic and granulocytic ehrlichiosis, and bebesiosis.
Exercise ECG analysis and measurement using an expert system approach

The difficulties of computerized analysis and measurement of the ECG (electrocardiogram) during exercise testing are compounded by the increases in noise and signal complexity at higher workloads and heart rates. By incorporating a hybrid expert-system structure in the analysis approach, information from the serial exercise ECG records are submitted to statistical and heuristic decision-logic to improve the accuracy of detection and measurement algorithms. Thus, in a manner similar to an expert cardiologist, the ECG analysis utilizes findings from previous records to aid in its determinations during each current record as the exercise test progresses. <<ETX>>
Piezo- and pyroelectricity in polymer electrets and their applications

Typical thin film polymer space charge electret materials are polytetrafluoroethylene (FEP). The corresponding dipolar electret materials are polyvinylidene fluoride, PVDF, its copolymer with trifluoroethylene P(VDF-TxFE), odd nylons and several copolymers of vinylidene cyanide, VDCN. The dipolar electrets display piezo- and pyroelectric responses. The present paper reviews briefly the properties of PVDF, P(VDF-TxFE), odd nylon and VDCN electrets and some applications.
Comparison of power quality aspects of switched reluctance and permanent magnet brushless DC motor

Solid state controlled drive systems are viewed as nonlinear loads by AC mains as they generate harmonic currents and create a reactive power burden on the grid. This paper presents a comparison of power quality aspects of switched reluctance and permanent magnet brushless DC motor drives. The key issues covered under power quality comparison are reactive kVA drawn, harmonic spectrum, total harmonic distortion and power factor of the two drives. Experimental results are presented for the motor operating at different loading conditions. A comparison of the results is carried out to assess the level of pollution caused to the utility by each drive system.
Iterative algorithms in irregular sampling: a first comparison of methods

The authors discuss a series of numerical experiments, aiming at the comparison of several iterative algorithms designed to reconstruct band-limited signals from irregularly spaced samples. The authors give a short description of these algorithms and then discuss possible criteria for the quality or performance of these algorithms. It turns out that appropriate criteria for such an evaluation are more involved than one might think from the literature. Among the properties discussed are various notions of speed, measures of the stability of the reconstruction algorithms and the range in which complete reconstruction is performed. The authors concentrate on the representation of the one-dimensional problems, although the underlying theory has been developed for several dimensions. Only qualitative statements are given. <<ETX>>
Design for optimum performance–to–power ratio of a continuous–time ΣΔ modulator

Low-power is a key issue in designing A/D converters for battery powered applications like cellular phones. A continuous-time ΣΔ modulator is well suitable for these applications [1] because of its low-power consumption, which is mainly determined by the noise and distortion requirements. In this paper the relation between power of the input stage and distortion of a continuous-time base-band ΣΔ modulator is analysed. As noise and distortion requirements of the first stage are most stringent, its contribution to the total power consumption of the ΣΔ modulator is dominant. From the theoretical results, a strategy for designing a low-power and high performance ΣΔ modulator is determined. Using this strategy a low-power low-distortion 4th-order ΣΔ modulator has been designed.
Endovascular coil embolization for recurrence of intracranial aneurysms more than 10 years after clipping

Abstract We report three cases of endovascular coil embolization for recurrent cerebral aneurysm after neck clipping more than 10 years previously. In two cases, their first subarachnoid hemorrhage was treated in other hospitals and the details of follow-up after discharge were unknown. After their second subarachnoid hemorrhage recurred 15 and 30 years, respectively. The remaining patient, who was treated in our center, was followed by magnetic resonance imaging 5 years after surgery but since then she didn’t go to our center. She came to our center for follow-up examination 10 years after the first surgery. The digital subtraction angiography showed recurrence of clipped aneurysms in all patients. All of them underwent endovascular coil embolization and total obliteration of the aneurysms without complications related to the procedures. Endovascular coil embolization is an alternative modality to direct surgery for cerebral aneurysms, especially for recurrence after clipping. Endovascular coil embolization of residual aneurysms after surgery may be the treatment of choice because of the difficulties in second direct surgery. We conclude that it is necessary to perform follow-up evaluations after surgery, even if the complete obliteration of aneurysms is performed. Current medical literature does not provide recommendations for the duration of follow-up after aneurysm clipping. The authors suggest that this period perhaps be at least a decade.

Memory Efficient and Robust Software Implementation of the Raycast Algorithm

In this paper we propose two novel software implementations of the ray-casting volume rendering algorithm for irregula r grids, called ME-Raycast (Memory Efficient Ray-casting) and EME-Raycast (Enhanced Memory Efficient Ray-Casting). Our algori thms improve previous work by Bunyk et al [1] in terms of complete handling of degenerate cases, memory consumption, and type of cell allowed in the grid (tetrahedral and/or hexahedral). T he use of a more compact and non-redundant data structure, allowed us to achieve higher memory efficiency. Our results show cons istent and significant gains in the memory usage of ME-Raycas t and EME-Raycast when compared to Bunyk et al implementation. Furthermore, our results also show that ha ndling of degenerate cases generates accurate images, correctly rendering all t he pixels in the image, while Bunyk et al implementation fails in rendering up to 38 pixels in the final image. When we compare our algorith ms to other robust rendering algorithm, like ZSweep [2], we have considerable performance gains and competitive memory consumption. We conclude that ME-Raycast and EME-Raycastare efficient methods for ray-casting that allow in-core render ing of large datasets with no image errors.
Positional and Grammatical Variations of Time Words in Takivatan Bunun

Takivatan Bunun, an Austronesian language spoken in Taiwan, has a dedicated class of words expressing time, place, and manner. These words can occur in various positions in the clause, each of which is associated with a distinct grammatical behavior. In this article, I discuss positional and associated grammatical variation of the four roots that most commonly express temporal location in the Takivatan corpus: dip ‘then’, qabas ‘in former times’, laupa ‘now’, and haip ‘today’. I conclude that the positional variability of Takivatan time words is grammatically meaningful and not the result of random variation. Finally, I suggest that it can be best explained in terms of functional motivations and historical factors that are common to various Austronesian languages in Taiwan.
Broadcast in sparse conversion optical networks using fewest converters

Wavelengths and converters are shared by communication requests in optical networks. When a message goes through a node without a converter, the outgoing wavelength must be the same as the incoming one. This constraint can be removed if the node uses a converter. Hence, the usage of converters increases the utilization of wavelengths and allows more communication requests to succeed. Since converters are expensive, we consider sparse conversion networks, where only some specified nodes have converters. Moreover, since the usage of converters induces delays, we should minimize the use of available converters. The Converters Usage Problem (CUP) is to use a minimum number of converter so that each node can send messages to all the others (broadcasting). In this dissertation, we study the CUP in sparse conversion networks. We design a linear algorithm to find a wavelength assignment in tree networks such that, with the usage of a minimum number of available converters, every node can send messages to all the others. This is a generalization of [34], where each node has a converter. Our algorithm can assign wavelengths efficiently and effectively for one-to-one, multicast, and broadcast communication requests. A converter wavelength-dominates a node if there is a uniform wavelength path between them. The Minimal Wavelength Dominating Set Problem (MWDSP) is to locate a minimum number of converters so that all the other nodes in the network are wavelength-dominated. We use a linear complexity dynamic programming algorithm to solve the MWDSP for networks with bounded treewidth. One such solution provides a low bound for the optimal solution to the CUP.
Ortaokul 6. ve 7. Sınıf Öğrencilerinin Bilimsel Model ve Modelleme Hakkındaki Görüşlerinin Bir Yaz Bilim Kampı Süresince Gelişimi

In this qualitative study, the influence of a ten-day science camp on elementary students’ views about scientific model and modeling was investigated. Twenty-four 6th and 7th grade students participated to the study. The general aim of the science camp was to introduce Nature of Science (NOS). One of the special aims of the science camp was to introduce scientific model and modeling as an aspect of NOS. Students’ views about scientific model and modeling were investigated by Views of the Nature of Science Version D (VNOS D) question “what is the scientific model? ” and open-ended probe questions in the interviews before and after the science camp. Qualitative data were analyzed by using interpretive analysis. Codes and themes acquired by students’ views before and after the science camp were compared and interpreted to determine the change in the students’ views. According to the results of the study, it can be said that students didn’t know what scientific model was before the camp. However, after the science camp, as a result of activities which aimed at introducing scientific model and modeling, they were able to conceptualize that scientific model is a kind of scientific knowledge and were able to define scientific model by stating that scientific model is based on data and thus they are the product of scientific research and experiments.
Intermodulation Effects in Limiter Amplifier Repeaters

A method is presented for analyzing intermodulation (IM) spectra in limiting amplifiers using a statistical approach. Engineering approximations are derived for the case of a large number of input signals. The accuracy appears to be good down to seven signals. The approach permits analysis of arbitrary locations (in frequency) of the input signals. Possible ways of reducing IM interference in limiting satellite repeaters are discussed. The analysis is generally restricted to the ideal hard-limiting amplifier however, its applicability to other nonlinear characteristics is illustrated. Additional sources of degradation, such as amplitudemodulation-frequency-modulation (AM-FM) conversion and system phase nonlinearity, are not treated.
The limitations of modeling finite state grammars with sim-ple recurrent networks

A thermal barrier system for use in a pressure vessel, such as a pre-stressed concrete pressure vessel housing the pressurized primary circuit of a gas-cooled nuclear reactor, in which there is provided a metal liner, stud members fixed to the metal liner, an inner flexible membrane fixed to the stud member, and porous insulation held between the liner and the membrane.
Intermodulation in CDMA

Using a soft limiter of the error function type, the authors have applied the time domain Fourier expansion method to analyze intermodulation in multiplexing of CDMA signals. The individual three-tone third-order intermodulation component, normalized with respect to the signal in CDMA, has the same magnitude as that in FDMA except for the reduction by the processing gain. The intermodulation components in FDMA are distributed among all the frequency channels, whereas all the intermodulation components fall on each CDMA channel in a radio carrier band. In practical cases the intermodulation to signal ratio in CDMA is only slightly lower than that in FDMA. However, a CDMA system with digital coding protection and RAKE receiver is expected to need less signal power.
ISPRS Test Project on Urban Classification and 3D Building Reconstruction: Evaluation of Building Reconstruction Results

The evaluation of building reconstruction results is based on an expansion of the method described in (Rutzinger et al., 2009). The software used for evaluation reads the reference and the roof plane detection results, converts them into a label image and then carries out the evaluation as described in the paper. When generating the label image, each pixel is assigned to the highest roof plane available at the respective X,Y position. The correspondence analysis between the roof planes is carried out in the same way as described for a comparison of object detection results in (Rutzinger et al., 2009). The output consists in a text file containing the evaluation results and in a few images that visualize these results.
Hybrid fault-tolerant control of aerospace vehicles

We describe our recent results (2001) related to the design of hybrid online failure detection and identification and adaptive reconfigurable control algorithms for aerial and space vehicles. Our approach is based on the multiple models, switching and tuning methodology and its extensions, and has been demonstrated as an efficient tool for hybrid fault tolerant control under subsystem and component failures and structural damage.
Frameworks for representing science teachers' pedagogical content knowledge

Over the past five years we have been involved in a research project that has attempted to recognise and then represent the pedagogical content knowledge (PCK) of successful Australian science teachers. The aim has been to capture, document and share teachers' PCK about specific science topics in ways that may be accessible to teachers and researchers involved in science education. In this paper, we illustrate the two integrated ways we have represented science teachers' topic specific PCK and discuss the theoretical framework that has informed our choice of representation.
Comparing Standing Balance at Real and Virtual Elevated Environments

The study evaluated the efficacy of a surround-screen virtual reality (SSVR) system in simulating heights for studying human postural balance at elevation. Twenty four subjects performed standing tasks at 9-m elevation and ground level, on firm and deformable surfaces, in a real environment (RE) and a comparable virtual environment (VE). The RE was the interior of the high-bay laboratory at the National Institute for Occupational Safety and Health (NIOSH) in Morgantown, West Virginia; the VE simulated this environment in the SSVR system. Medial-lateral and anterior-posterior body sways and mean velocity of the human center-of-pressure displacement were collected using a force platform. The results indicated that the sway parameters were similar in VE and RE at elevation on both firm and deformable surfaces. At ground level, the sway parameters were significantly increased in the VE compared to the RE on a deformable surface, but not on a firm surface. It appears that visual simulation of elevated environments within a SSVR is adequate for studying the risk factors leading to losing balance and fall incidents.
Program and data transformations for efficient execution on distributed memory architectures

This report is concerned with the efficient execution of array computation on Distributed Memory Architectures by applying compiler-directed program and data transformations. By translating a sub-set of a single-assignment language, Sisal, into a linear algebraic framework it is possible to transform a program so as to reduce load imbalance and non-local memory access. A new test is presented which allows the construction of transformations to reduce load imbalance. By a new expression of data alignment, transformations to reduce non-local access are derived. A new pre-fetching procedure, which prevents redundant non-local accesses, is presented and forms the basis of a new data partitioning methodology. By applying these transformations in a straightforward manner to some well known scientific programs, it is shown that this approach is competitive with hand-crafted methods.
A primer on implementing compressed simulated annealing for the optimisation of a constrained simulation model in Microsoft Excel

This short paper provides a simple introduction on how a simulation model implemented in Microsoft Excel® can be optimised using Visual Basic for Applications (VBA) programming and the compressed simulated annealing algorithm (Ohlmann et al., 2004; Ohlmann and Thomas, 2007). The standard simulated annealing procedure enters as a special case. Practical advice for determining the parameters that guide the stochastic search process in an annealing algorithm is also given.
