Adaptive input-output linearization of a switched reluctance motor for torque control (2002)

In this paper a nonlinear adaptive feedback linearizing torque control is designed for a fifth order model of a three phase switched reluctance motor (SRM) which includes both electrical and mechanical dynamics. This nonlinear adaptive control structure compensates for all the nonlinearities between inputs and outputs. In addition, it allows the use of a decoupling linear controller for motion tracking for one phase and stabilization for the two other phases. A validated nonlinear model of the SRM is used for system simulation. The control algorithm contains an adaptive scheme based on the parametrized model. A method based on flux observation is used to measure the instantaneous torque. Simulation results are given to demonstrate the effectiveness of the control method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Shape based learning for a multi-template method, and its application to handprinted numeral recognition (2002)

Character recognition using multi-template methods is promising. Higher classification performance can be achieved according to an increase in the number of templates. However, classification performance is saturated because there is classifiability loss in feature extraction. The paper proposes a new multi-template method which learns training patterns with character shape information assigned by the authors. This method uses contour feature and direction feature, and includes a character shape consistency test applied to the conventional multi-template methods. The paper presents experimental results obtained from handprinted numerals. On the ETL-6 database classification experiment the classification rate was 99.19% and the substitution rate was 0.03%. A higher classification rate could be achieved.
Classification of electrocardiographic P-wave morphology (2001)

The atrial activity of the human heart is normally visible in the electrocardiogram as a P-wave. In patients with intermittent atrial fibrillation, a different P-wave morphology can sometimes be seen, indicating atrial conduction defects. The purpose of this study was to develop a method to discriminate between such P-waves and normal ones. 20 recordings of each type were used in a classification which, based on impulse response analysis of the P-wave and linear discrimination between various parameters, produced a correct classification in 37 of the 40 recordings (sensitivity 95%, specificity 90%).

Crowd Monitoring and Localization Using Deep Convolutional Neural Network: A Review (2020)

Crowd management and monitoring is crucial for maintaining public safety and is an important research topic. Developing a robust crowd monitoring system (CMS) is a challenging task as it involves addressing many key issues such as density variation, irregular distribution of objects, occlusions, pose estimation, etc. Crowd gathering at various places like hospitals, parks, stadiums, airports, cultural and religious points are usually monitored by Close Circuit Television (CCTV) cameras. The drawbacks of CCTV cameras are: limited area coverage, installation problems, movability, high power consumption and constant monitoring by the operators. Therefore, many researchers have turned towards computer vision and machine learning that have overcome these issues by minimizing the need of human involvement. This review is aimed to categorize, analyze as well as provide the latest development and performance evolution in crowd monitoring using different machine learning techniques and methods that are published in journals and conferences over the past five years.
Double Star Measurements with a Three Inch Tasco Telescope (2008)

Observations were made of three double stars with known separations and position angles using a three inch 1960's Tasco telescope equipped with a Meade astrometric eyepiece. After these observations were completed, their mean values were compared with cataloged values. It was concluded that, under appropriate conditions, a modest aperture Tasco telescope can provide remarkably accurate and precise results.

[Reduction of atrial fibrillation. New concepts, new strategies]. (1995)

Restoring sinus rhythm is patients with non-valvular atrial fibrillation has two objectives: restore haemodynamic performance and reduce the risk of thromboembolism. Whether the cardioversion is spontaneous or induced with drugs or electroshock, the process itself carries the risk of systemic embolism attributed to the transitory inactivity of the left atrium. Current practice of giving anticoagulants at least 4 weeks before electric cardioversion is a compromise between the embolic risk of cardioversion estimated at 0.4 to 0.8% and haemorrhagic complications related to low blood coagulability estimated at about 1% per year. The advent of transoesophageal echography has made it possible to study the atrium in detail in search of thrombi. The result has been a revolution in our concepts and therapeutic approach to atrial fibrillation and cardioversion. Recent studies have shown that "rapid cardioversion" associated with minimal 48-hour anticoagulation with heparin IV and transoesophageal echography to eliminate a thrombus in the atrium and/or the atrial appendage can be proposed without increasing the risk of embolism. Besides simplifying the therapeutic protocols (but at the cost of the semiinvasive nature of the transoesophageal echocardiography), this method also has the merit of restoring atrial function rapidly, particularly in cases of recent onset arrhythmia.
The CUP1 promoter of Saccharomyces cerevisiae is inducible by copper in Pichia pastoris (2000)

We report the construction of a Pichia pastoris integrating vector which contains the inducible CUP1 promoter from Saccharomyces cerevisiae. We show that the promoter is indeed inducible by copper when used in P. pastoris and that the level of induction is dependent on the amount of copper in the medium.

Plant Volatiles as a Defense against Insect Herbivores (1999)

Leaves normally release small quantities of volatile chemicals, but when a plant is damaged by herbivorous insects, many more volatiles are released. The chemical identity of the volatile compounds varies with the plant species and with the herbivorous insect species. These volatiles attract both
The Human OCT-4 Isoforms Differ in Their Ability to Confer Self-renewal (2006)

OCT-4 transcription factors play an important role in maintaining the pluripotent state of embryonic stem cells and may prevent expression of genes activated during differentiation. Human OCT-4 isoform mRNAs encode proteins that have identical POU DNA binding domains and C-terminal domains but differ in their N-terminal domains. We report here the cloning and characterization of the human OCT-4B isoform. Human OCT-4B cDNA encodes a 265-amino acid protein with a predicted molecular mass of 30 kDa. Embryonic stem (ES) cell-based complementation assays using ZHBTc4 ES cells showed that unlike human OCT-4A, OCT-4B cannot sustain ES cell self-renewal. In addition, OCT-4B does not bind to a probe carrying the OCT-4 consensus binding sequence, and we demonstrate that two separate regions of its N-terminal domain are responsible for inhibiting DNA binding. We also demonstrate that OCT-4B is mainly localized to the cytoplasm. Overexpression of OCT-4B did not activate transcription from OCT-4-dependent promoters, although OCT-4A did as reported previously. Furthermore, transcriptional activation by human OCT-4A was not inhibited by co-expression of OCT-4B. Taken together, these data suggest that the DNA binding, transactivation, and abilities to confer self-renewal of the human OCT-4 isoforms differ.
An Area Efficient Early ${Z}$-Test Method for 3-D Graphics Rendering Hardware (2008)

In this paper, we propose a new early z-test which requires a minimized internal memory while removing redundant z and color reads as well as texture reads. The proposed method determines whether a pixel is screened by a certain mask plane which is containing the history of a pixel's appearance in front of it. If a pixel is screened by the plane, it can be removed. Given an initial position, the method adaptively updates the plane position to maximize the rejected pixels. As a result, on average 39.9% of the memory bandwidth and 21.2% of total power consumption is saved with only a 256 B on-chip memory. The proposed method was implemented into a multimedia system-on-chip with 61 k application-specific integrated circuit (ASIC) gates using a 0.13-mum CMOS process technology.
Iconic programming for teaching the first year programming sequence (2002)

Research has been undertaken to evaluate the effectiveness of using iconic (as opposed to visual) programming environments in teaching the first two computer programming courses. The co-authors have developed a Windows-based iconic programming language named BACCII. BACCII allows the user to program with icons representing all the major programming constructs and data structures within a syntax-directed environment. The user can then generate syntactically correct code for any one of several text-based languages. This system has previously been used as a supplement to teach a Pascal-based introductory computer science (CSI) course required of both computer science and electrical engineering majors; the empirical results showed a significant increase in learning and comprehension, despite the fact that there were virtually no supplemental teaching materials for BACCII available at that time. Additional research has supplied object-oriented extensions to BACCII for use in the data structures/object-oriented programing (CS2) course. Current research concerns the development of a complete set of course material for the use of BACCII in teaching both CSI and CS2 using C++. Lecture notes, text, and lab manuals are under development. An experiment will be run using the new teaching materials at Texas Tech during the 1995-96 school year. Future research hopes to extend this program to series of pilot programs at other institutions.
Rotary router (2007)

The trend towards increasing the number of processor cores and cache capacity in future Chip-Multiprocessors (CMPs), will require scalable packet-switched interconnection networks adapted to the restrictions imposed by the CMP environment. This paper presents an innovative router design, which successfully addresses CMP cost/performance constraints. The router structure is based on two independent rings, which force packets to circulate either clockwise or anti-clockwise, traveling through every port of the router. It uses a completely decentralized scheduling scheme, which allows the design to: (1) take advantage of wide links, (2) reduce Head of Line blocking, (3) use adaptive routing, (4) be topology agnostic, (5) scale with network degree, and (6) have reasonable power consumption and implementation cost. A thorough comparative performance analysis against competitive conventional routers shows an advantage for our proposal of up to 50 % in terms of raw performance and nearly 60 % in terms of energy-delay product.
Prophylactic Administration of Calf Lung Surfactant Extract Is More Effective Than Early Treatment of Respiratory Distress Syndrome in Neonates of 29 Through 32 Weeks' Gestation (1993)

Prophylaxis was associated with less development of moderate RDS (7% vs 12%), less need for retreatment (5% vs 9%), less need for mechanical ventilation or supplemental oxygen during the first 4 days, and fewer deaths or less requirement for supplemental oxygen at 28 days (5% vs 9%). Although 1-minute Apgar scores were significantly lower in the prophylaxis group, the difference disappeared by the 5-minute score and there was no difference in the incidence of asphyxia-related complications. Sixty percent of the neonates assigned to early treatment received endotracheal intubation and 43% received calf lung surfactant extract at a median age of 1.5 hours. When data were analyzed by gestational age and birth weight subgroups, most of the differences could be attributable to babies born at 30 weeks or less or weighing less than 1500 g, probably because of the higher incidence of surfactant deficiency in this more immature subgroup.
Improved X-Band FM Discriminator (Short Paper) (1986)

The technique of coherent carrier-addition, using injection synchronization of a narrow-band Gunn oscillator, for improving the performance of an X-band frequency discriminator has been examined in detail. The discriminator is implemented from a single magic tee, two adjustable AM detectors, two sliding shorts, a circulator, an isolator, and a difference amplifier of gain unity. Experimental results are presented in partial support of the conclusions of the analysis. Normal operation of the discriminator in absence of the coherent carrier is also described as a special case of the above analysis.
Cooperative robustness to dephasing: Single-exciton superradiance in a nanoscale ring to model natural light-harvesting systems (2014)

We analyze a one-dimensional ring structure composed of many two-level systems, in the limit where only one excitation is present. The two-level systems are coupled to a common environment, where the excitation can be lost, which induces super- and subradiant behavior. Moreover, each two-level system is coupled to another independent environment, modeled by a classical white noise, simulating a dephasing bath and described by the Haken-Strobl master equation. Single-exciton superradiance, an example of a cooperative quantum coherent effect, is destroyed at a critical dephasing strength proportional to the system size, showing robustness of cooperativity to the action of the dephasing environment. We also show that the coupling to a common decay channel contrasts with the action of dephasing, driving the entanglement decay to slow down on increasing the system size. Moreover, after a projective measurement which finds the excitation in the system, the entanglement reaches a stationary value, independent of the initial conditions.
Induction of arthritis in C57B1/6 mice by chlamydial antigen. Effect of prior immunization or infection. (1988)

Antigen from a Chlamydia trachomatis biovar, mouse pneumonitis agent (MoPn), was used to produce an inflammatory arthritis by inoculation in the knee joints of C57B1/6 mice. The production of arthritis was strongly dependent on prior sensitization to chlamydiae by subcutaneous immunization in either sex or genital infection in females. In unimmunized animals quantitatively less inflammation, fibrin exudation, and pannus formation developed than in immunized counterparts. In neither uninjected nor McCoy or HeLa Cell antigen-treated joints did arthritis develop. The arthritis produced was more pronounced at 7 than at 2 days after intraarticular challenge and showed minimal residual changes at 21 days. Residual changes included subsynovial hyperplasia. In genitally infected female mice less severe arthropathy developed than in subcutaneously immunized female mice after intraarticular challenge with formalin-inactivated chlamydial antigen. However, in infected mice challenged with chlamydiae inactivated by ultraviolet irradiation a severe arthritis with destructive pannus developed, suggesting alteration of antigenicity by formalin inactivation. The strong association of the arthritis with the presence of chlamydial antibody suggests its use as a model of human Reiter's disease in which prior sensitization to Chlamydia is an important factor.
Galectin-1 Is a Major Receptor for Ganglioside GM1, a Product of the Growth-controlling Activity of a Cell Surface Ganglioside Sialidase, on Human Neuroblastoma Cells in Culture (1998)

Cell density-dependent inhibition of growth and neural differentiation in the human neuroblastoma cell line SK-N-MC are associated with a ganglioside sialidase-mediated increase of GM1 and lactosylceramide at the cell surface. Because these glycolipids expose galactose residues, we have initiated the study of the potential role of galectins in such cellular events. Using specific antibodies, galectin-1 but not galectin-3 was found to be present at the cell surface. Assessment of carbohydrate-dependent binding revealed a saturable amount of ligand sites approaching 2.6 x 10(6) galectin-1 molecules bound/cell. Presence during cell culture of the sialidase inhibitor 2-deoxy-2,3-dehydro-N-acetylneuraminic acid or of the GM1-binding cholera toxin B subunit effected a decrease of the presentation of galectin-1 ligands by 30-50%. The assumption that GM1 is a major ligand for galectin-1 was reinforced by the correlation between the number of carbohydrate-dependent 125I-iodinated GM1-neoganglioprotein binding sites and the amount of immunoreactive surface galectin-1, the marked sensitivity of probe binding to the presence of anti-galectin-1 antibody, and the inhibition of cell adhesion to surface-immobilized GM1 by the antibody. The results open the possibility that the carbohydrate-dependent interaction between ganglioside GM1 and galectin-1 may relay sialidase-dependent alterations in this cell system.
Sleep apnea syndrome — An alternative treatment to tracheostomy (1981)

Two patients with obstructive sleep apnea syndrome had polygraphic recordings demonstrated upper airway obstruction and sleep with extremely short sleep latency, severely disturbed nightsleep resulting in sleep deprivation, and excessive daytime sleepiness. Radiological investigation showed the upper airway obstruction to be caused by the tongue falling back occluding the pharynx. Nasopharyngeal intubation relieved the symptoms. The patients were trained to perform this treatment themselves every night, demonstrating that this treatment is an attractive alternative to the conventional tracheotomy.

Difference-Set Cyclic Codes (1966)

Codes exist which are capable of correcting large numbers of random errors. Such codes are rarely used in practical data transmission systems, however, because the equipment necessary to realize their capabilities — that is, to actually correct the errors — is usually prohibitively complex and expensive. The problem of finding simply implemented decoding algorithms or, equivalently, codes which can be decoded simply with existing methods, is perhaps the outstanding unsolved problem in coding theory today. In this paper, a new class of random-error-correcting cyclic codes is defined. These codes have two very desirable features: the binary members of the class are nearly as powerful as the best-known codes in the range of interest, and they can be decoded with the simplest known decoding algorithm. Unfortunately there are relatively few codes with useful parameters in this class, despite the fact that the class is infinite.
Human-robot collision avoidance with RFID sensors using fuzzy logic and extended Kalman filter (2013)

At the down of the new millennium, robotic has tendency to contribute to a major transformation in scope and dimension. From a largely dominant industrial focus, robotics is expending into challenge of dynamic unstructured environment. The emerging robots will increasingly touch people and their lives by interacting with, assisting, serving and exploring with them. In this paper, we propose a new strategy for human robot collision avoidance with position estimation. We have used RFID sensors for environment perception since they are frugal. We have used the fuzzy logic algorithm which we adapted to RFID sensor model in order to avoid collision with humans and we corrected the robot position with the well known Extended Kalman Filter. Finally we present some experiments which we have done with our experimental robot AX11. Figure 1: AX11 robot equipped with sonar sensors
