Metrics and visualization tools for surface mesh comparison

This paper describes a system for comparing surface meshes using different distance metrics and mapping the results to different visual presentations. Hierarchical and multi- resolution (HMR) methods produce meshes with different levels of details. Different HMR methods produce meshes with varying quality. The surface mesh comparison system presented here allows the user to qualitatively compare and investigate the merits of the meshes produced by different HMR algorithms as well as how different resolution meshes degrade as they are simplified.
Models and Algorithms for Fairness and Priority in Scheduling

In this thesis we address the problem of fair and priority scheduling. We focus our attention on systems characterized by an infinite computation, a discrete decomposition of tasks into atomic operation and a known-a-priori set of precedence-constraints among the activities to be performed. We analyze two fairness and two priority specifications related to the frequency of occurrence of activities. We solve the scheduling problem both when the scheduler has complete control upon the system's execution and when the environment can influence the outcome of a scheduling plan.
Facebook use in the learning environment: do students want this?

The Net Generation (those born in or after 1980) rely heavily on ICTs for social and professional interactions, and it has been suggested that they have the expectation that technology will be an integral part of their education. At the same time, it is argued that Facebook has educational potential, and that today's learners should be encouraged and supported to use Web 2.0 technologies for learning in formal education. However, there is growing evidence that the value of Facebook in the educational context does not relate to formal learning at all, but to the ‘social networking’ elements of the site. This Viewpoint article discusses the results of a study to explore students' views towards the use of Facebook in the university setting, especially with regard to learning and integration into university life. The findings suggest support for informal rather than formal learning use of Facebook within the university setting.
Modelling backscatter in bare organic soils

A study was conducted in 1996 and 1997 to develop a model that would simulate radar backscatter in histosols with different field managements. Measurements were made under various soil moisture content using the Canadian Remote Sensing Centre scatterometer. Seedbed and harrow in 1996, and harrow, moldboard and chisel treatments in 1997, were applied to plots with rows oriented parallel and perpendicular to the view angle of the antennas. The scatterometer operated in two bands (C, L), four polarisations (HH, HV, VH, VV) and four incidence angles (25/spl deg/, 30/spl deg/, 40/spl deg/, 50/spl deg/). This paper presents the methodology, the models and some results from 1996 data analysis. Actual models were not adequate to simulate the backscatter in seedbed plots except at some combinations of incidence angle and polarisation. They were not able to simulate the angular response of the signal when rows were perpendicular to view angle. Calibration and further development is on-going with 1997 data.
Optimization of particle-in-cell codes on reduced instruction set computer processors

General strategies are developed to optimize particle‐cell codes written in Fortran for reduced instruction set computer processors which are commonly used on massively parallel computers. These strategies include data reorganization to improve cache utilization and code reorganization to improve efficiency of arithmetic pipelines. Results show performance improvements of 1.4–3.4 times can be achieved. © 1996 American Institute of Physics.

Guidelines for researchers and practitioners designing software and software trials for children with autism

This article presents practical guidelines for the design of interactive software for children with autism. Many existing software design techniques rely on social interaction and so are not appropriate for this group, and little practical guidance is available. The guidelines presented are based on research experiences during the development of an interactive software game called TouchStory, which was designed to promote an understanding of narrative structure while adapting to the learning needs of individual children with autism. Our results indicate that some children with autism were actively engaged in self‐directed, curiosity‐driven learning, and found TouchStory enjoyable, even after repeated exposures on as many as 20 occasions. The guidelines are not limited to the appearance and behaviour of the software system, and may be fundamental to the research questions asked and the approach adopted. They provide a useful basis for furthering our understanding of the provision of assistive technology for children with autism.
Literacy for All in 100 Days? A research-based strategy for fast progress in low-income countries

In low-income countries many students are marginalized very early and remain illiterate. In grades 1-3 they attend rarely, though they may officially drop out in grade 4. Many others graduate from primary school without having learned letter values. The worrisome outcomes, despite much donor investment in low-income countries, have prompted scrutiny of the methods, and textbooks used to make students literate. This document offers insights from cognitive neuroscience and evidence suggesting that students can be taught basic literacy within the first semester of grade 1, if taught in consistently spelled languages. Teaching students at risk of dropout to read as early as possible enhances equity. However, the reading methods used in many countries are complex and hard for teachers to execute. They pertain to high-income countries and to certain western European languages. English but also French, Portuguese, and Dutch have complex spelling systems. English in particular requires three years of learning time. (French requires about two). Reading instruction for English is expensive and complex. Lists of whole words must be learned, vocabulary and early training in predictions are needed in order to make sense of words that cannot be sounded out. Learning must be started at kindergarten, parents must help at home, and many weaker students require remedial instruction. Since English is an official language in many countries, the travails of learning to read in this language have been considered the normal fate of reading. Overall, reading methods must be resilient to the vicissitudes of implementation. Many activities work well in higher-income countries or small pilots, but at scale-up they sink. Governments and donors should train up to existing capacity, rather than try to raise capacity to the requirements of complex methods.
Time Delay Model for SRAM Compiler

In this paper, we introduced an effective time delay model for SRAM compiler, which represents an important performance of SRAM. Our method divide the delay time into several periods, including decoder delay, word line delay, bit line delay and SA delay. The theory is useful in predicting the delay time when the SRAM size is changed. Simulations by Hsim in 65nm CMOS process proves a high accuracy.
Computational imaging for stop-motion animated video productions

Creating movies using stop-motion technology remains a fascinating approach for storytelling even in the era of digital cinema. A huge number of professional and semiprofessional clips that were produced as fan art can be watched on Internet video platforms and serve as testimonial for the unbroken interest in unleashing creative potential using this technology. However, producing content using stop motion remains a cumbersome task that raises production costs, especially for full-length movies. Consequently, a trend can be observed even for successful television series that were originally produced using stop motion in which the production scheme was changed to computer animation. Against this background, we propose a production scheme for stop-motion-animated movies that has the potential to lower the production costs while increasing the quality of the resulting content. By using a static multicamera array and algorithms from the field of computational imaging, our technology allows artistic effects to be created in the post-production that are difficult to realize using conventional stop-motion production methods. Our approach allows changing the depth of field, smoothly moving the camera along virtual camera paths, and upsampling the frame rate of the stop-motion video in high quality. All effects are computed and applied in post-production, while all intrinsic and extrinsic parameters of the cameras remain static during the whole production. To demonstrate the practicability, results are shown from a stop-motion video that has been produced using the proposed approach.
Creative Task Force Attack on Profit Loss Due to Formation Damage

Many currently accepted drilling and producing practices cause appreciable formation damage. Major changes in field operations are required to prevent or alleviate this damage. In planning a coordinated attack on formation damage, the Creative Task Force offers a proved approach to bring about desired results. Case histories of major task force projects relating to formation damage are presented. Because of the potential economic impact on the oil and gas business, an all out attack on formation damage should be solidly supported by management of the various oil and gas producers, service companies, drilling contractors, and workover contractors on a worldwide basis.

Detection of cytoplasmic immunoglobulin in well‐differentiated lymphoproliferative diseases by the immunoperoxidase method

Lymph node specimens from 101 patients diagnosed as having a well‐differentiated lymphoproliferative disease were studied by the peroxidase–anti‐peroxidase (PAP) method for the presence of intracyto‐plasmic immunoglobulin (Ig). In all but 22 cases, the initial diagnostic material consisted of lymph node biopsy specimens interpreted histologically as showing well‐differentiated lymphoproliferative disease. Based on hematologic and immunologic data, patients who had had a biopsy were subclassified as having (1) well‐differentiated lymphocytic lymphoma (WDL) when no absolute lymphocytosis or monoclonal gammopathy was present (22 patients), (2) lymphoproliferative disease with monoclonal gammopathy (MG) when a monoclonal immunoglobulin was demonstrated in the serum (14 patients), and (3) chronic lymphocytic leukemia (CLL) when the absolute lymphocyte count was more than 4000/mm3 and no monoclonal gammopathy was evident (43 patients). Twenty‐two known cases of CLL in which only autopsy tissue was available were added to this study. A monoclonal intracytoplasmic immunoglobulin was demonstrable in 4 of the 22 WDL cases (18%), in 13 of the 14 MG cases (93%), and in 3 of 62 CLL cases (5%). In 3 cases of CLL, tissues obtained at autopsy reacted with all antisera used. In the MG cases, a good correlation was found between the results of the PAP method and the serum immunoelectrophoretic findings. The lymphoid cell populations, including the plasmacytoid and plasma cells, were entirely monoclonal in 10 and predominantly monoclonal in 3 MG cases. In the latter, a small percentage of the plasma cell population was found to be polyclonal. In 6 of the 18 WDL cases and in 10 of the 59 CLL cases that were negative for immunoglobulin in the lymphoid cells, rare plasma cells were found. These small plasma cell populations were polyclonal. A good correlation between periodic‐acid‐Schiff positivity and the presence of intracytoplasmic immunoglobulin was observed in the MG cases; no such correlation was evident in the WDL and CLL cases.
Leitlinie zur Langzeit-Sauerstofftherapie

Zusammenfassung Die Langzeit-Sauerstofftherapie hat einen hohen Stellenwert sowohl zur Verminderung der Letalität als auch zur Verbesserung der Leistungsfähigkeit bei Patienten mit chronischen Lungenerkrankungen. Die Grundvoraussetzung für die Langzeit-Sauerstofftherapie ist die adäquate Diagnostik und Indikationsstellung. Sinnvoll ist eine kausale Unterscheidung in eine chronische hypoxämische oder hyperkapnische respiratorische Insuffizienz, aus der sich die Differentialindikation zur nichtinvasiven Beatmung ergibt. Die revidierte Leitlinie behandelt u. a. die Diagnostik und die Indikation bei chronischen Lungen- und Herzerkrankungen sowie den Einsatz in der Palliativmedizin und gibt eine detaillierte Beschreibung der verfügbaren Sauerstoffsysteme. Die Leitlinie soll dazu beitragen, die teilweise bestehende Unter-, Fehl- und Überversorgung zu vermeiden. Zudem wird im Kapitel „Postakute Sauerstofftherapie“ die im Alltag relevante, bisher nicht definierte Vorgehensweise für die Verschreibung einer Sauerstofftherapie am Ende eines stationären Aufenthaltes für den häuslichen Bereich diskutiert. Ein weiterer wichtiger Punkt, die korrekte Verordnung mobiler Sauerstoffsysteme, wird auch in der Leitlinie dargestellt. Die vorliegende aktualisierte Leitlinie zur Langzeit-Sauerstofftherapie löst die alte im Jahr 2008 publizierte Version ab.
Interactive Computer-based Game for Decision-making in Ecology

This paper describes a prototype Ecology Decision Game which has been developed for experimental use within IBM. The paper is directed to those in ecology desiring to use similar techniques in developing programs that interrelate computing, management science, mathematics, and APL for training and educational purposes. The game is implemented in two modes: an author mode, which permits an author to write his own scenario; and a player mode, which enables a person to play the game. Features of the game exploit interactive capabilities for both modes. The particular scenario written for the game treats decision-making in the environmental area of solid-waste management. Three submodules explore progressively more complicated situations that give rise to management science problems: shortest route, transportation, andm aximal flow. By active and passive role-playing, and controlled and uncontrolled learning, the player is given the opportunity to use quantitative tools to refine his subjective judgments.
Online plain English and readability resources

To encourage individuals and businesses to write in simpler, more readable English, private and government-backed enterprises have created a number of freely available online resources. While most relate to general English use, some are devoted to writing about medical matters. In this summary article, I take a brief look at what is available and how good it is.
Geometric Definition of the Hidden Part of a Line Drawing in a Sketch-to-Solid Methodology

ABSTRACTThe method presented in this paper is part of a 3-step reconstruction methodology for the extraction of a polyhedron from a single view natural sketch. In particular, the current paper focuses on the 2D geometric definition of the hidden part in a topologically reconstructed line drawing (intermediate wireframe sketch) as this is generated from the given natural sketch. The proposed method is based on the different topologic relations that exist in the hidden part of the intermediate sketch. Contrarily to other approaches it employees the cross-section criterion to ensure that the final fully-determined wireframe sketch is realizable. The proposed method is successfully applied to indicative line drawings with various combinations of visible and hidden elements.
Contention resolution by shared wavelength converters and fiber delay lines in an optical packet switch

Contention resolution techniques greatly affect the architecture and performance of an optical packet switch (OPS). Fiber delay lines (FDLs) and wavelength converters which can resolve the contention problem and provide acceptable performance, have been demonstrated in many OPS designs. However, the large hardware volume of the optical components limits the integration and scalability of the OPS system. In this paper, we propose a design that can efficiently utilize the wavelength converters and use a very limited number of FDLs. The performance of the proposed design has been evaluated by simulation. © 2003 Wiley Periodicals, Inc.

A decomposition based control design approach to output tracking for multivariable nonlinear non-minimum phase systems

We study the output tracking problem for a restricted class of square nonlinear non-minimum phase systems. Our approach is based on decomposing such systems into a minimum phase part and a non-minimum phase part. This decomposition approach leads to a simpler non-minimum phase problem than the original one. We also identify a class of tracking commands for which the output tracking problem has a solution. A multivariable flight control problem is used to demonstrate the approach.
CPSC 420-500: Program 3, Perceptron and Backpropagation

You will implement perceptron learning from scratch (see section 3 for details), and train it on AND, OR, and XOR functions. Then, you will take an existing backpropagation code (see section 4), train it and test it under different conditions and report your findings. The same three boolean functions will be used for the backpropagation learning. For further details on perceptrons and backpropagation, see the lecture slides and also Hertz et al. (1991). Specific submission instruction will be given in section 5 and section 6.
Benchmarking computer systems for robot control

The high computational burden posed by modern control algorithms often precludes their industrial application using present day microcomputers. We evaluate the computational load of different logical and arithmetic operations and the capabilities of several computing systems (software and hardware). Real-time limitations are alleviated through the adoption of general techniques associated with the data representation. Such techniques achieve not only a more efficient management of the computational resources but also provide a deeper insight on developments toward future computer control architectures. >
An Algorithms for Super-Resolution Reconstruction of Video Based on Spatio-Temporal Adaptive

For the weakness of conventional POCS algorithms, a novel spatio-temporal adaptive super-resolution reconstruction algorithm of video is proposed in this paper. The spatio-temporal adaptive mechanism, which is based on POCS super-resolution reconstruction algorithm, can effectively prevent reconstructed image from the influence of inaccuracy of motion information and avoid the impact of noise amplification, which exist in using conventional POCS algorithms to reconstruct image sequences in dramatic motion. Experimental results show that the spatio-temporal adaptive algorithm not only effectively alleviate amplification noise but is better than the traditional POCS algorithms in signal to noise ration.
THE ARCHITECTURE OF IDENTITY: Embedding privacy in market institutions

As the Internet becomes integrated into the institutional world around it, attention has increasingly been drawn to the diverse ways in which information technologies mediate human relationships. As an increasingly commercial Internet has been employed to capture personally identifiable information, privacy concerns have intensified. To analyse these matters more systematically, this article considers the ideas about human identity that have been implicit in the development of economics and computer science. The two fields have evolved along parallel tracks, starting with an assumption of perfect transparency and moving toward a more sophisticated appreciation of individuals' private informational states. Progress in the analysis and resolution of privacy problems will require that this evolution be taken seriously and continued.
Reliability evaluation of distribution systems with renewable distributed generation and load variation models

This paper presents a methodology for reliability evaluation of distribution systems with the presence of distributed generation (DG) based on different energy sources. The methodology considers the possibility of DG connection at the High Voltage (HV) and Medium Voltage (MV) buses of the distribution substation, as well as along the MV distribution network. The uncertainty of energy availability of time varying energy sources, such as the wind generation, and the chronological variation of the loads are included in the methodology. The network representation includes the main protection and reconfiguration devices, such as breakers, manual switches, automatic sectionalizers, reclosers and fuses. Some operative polices in relation to DG, such as islanded operation and protection schemes for network failures, as well as load shedding prioritization and load transfer between feeders, are analyzed.
Influence of the Number of Principal Components used to the Automatic Speaker Recognition Accuracy

This paper discusses possibilities to reduce dimensionality of the standard MFCC feature vectors by applying the technique of Principal Component Analysis (PCA). The reported experimental results suggest that PCA is an appropriate technique to reduce dimensionality without reducing the accuracy of recognition. The applied automatic speaker recognizer shows that already for a 14-dimensional PCA feature space, the recognition accuracy reaches the target value as in the 39-dimensional MFCC feature space. This gives motivation for further research towards more efficient speaker recognizers. Ill. 3, bibl. 9 (in English; abstracts in English and Lithuanian).

Heparin Induces Release of Phospholipase A2 into the Splanchnic Circulation

Cardiopulmonary bypass results in increased plasma activity of phospholipase A2 (PLA2) that appears to be caused by the administration of heparin. High PLA2 activity may be responsible for increased production of eicosanoids and, thus, may be implicated in various pathophysiologic events associated with cardiac surgery. To investigate the site of PLA2 secretion, blood samples were simultaneously collected from the radial artery, the pulmonary artery, and the hepatic vein at 2, 4, 6, and 20 min after systemic heparinization (350 U/kg). Within 2 min of the heparin injection, plasma activity of PLA2 increased 4- to 9-fold and remained so for at least 20 min. Two minutes after the heparin injection, PLA2 was significantly higher in the hepatic vein than in the radial artery (P < 0.01). No such difference was detected between pulmonary and radial arteries. When heparin was added to blood samples in vitro (5–100 U/mL), plasma activity of PLA2 did not increase, which suggests that the enzyme was not secreted by blood cells. Implications Heparin, given in the dosage required for cardiopulmonary bypass, caused release of phospholipase A2 into the splanchnic circulation.
