Fast panoramic video generation method using morphological corner detection

We present a method for building panoramic video for Video GIS. The panoramic video is composed of several images taken by adjacent cameras. The perspective transformation, which estimated from the appropriate corresponding pairs between the images, can construct the panoramic video without unwilling distortions. We use corner points for the corresponding feature, and morphological structures are utilized for fast and robust corner detection. We propose a criterion method of corner strength, which guarantees the robust detection of corner in any situations. For the transformation, 8-parameters are estimated from perspective equations, and bilinear color blending is used to construct a seamless panoramic video. Experiments show that our method yields good results in various conditions.
Monitoring System of Blind Areas in a Skiing Resort using a USN

ABSTRACT This paper introduces an efficient USN (ubiquitous sensor network) for monitoring blind areas in a skiing resort, developed as a part of u-Sport showcase project of Gangwon Province. Blind areas of a skiing resort are dangerous and/or steep areas located aroud ski slopes, which are rarely traveled and not easily seen by a ski patrol. If an accident occurs in such a blind area, the main control center of the sking resort can hardly recognize the accident and provide first aid and rescue services promptly. The blind area monitoring system proposed in this paper monitors a blind area of a skiing resort using five battery-powered sensor nodes each of which has an image sensor on it and wirelessly transmits images around the blind area to the main control center on a regular basis, therebly allowing real-time monitoring of the blind area and prompt rescue services in case of accidents. Additionally, the monitoring system provides an emergency button which skiers injured in the blind area can push. If the button is pushed, an image around the button and an alarm signal are transmitted to the main control center and therefore the main control center can take prompt actions for rescuing the injured skiers.Keywords:USN, Kangwon-do Yong-Pyeong, u_Sports, Blind Areas
Prevalence of smoking among nurses in the Ninth region of Chile

Background: Smoking is noxious for health and is considered a public health priority. The prevalence of smoking is increasing, specially in women. Among nurses, its prevalence is 42.7%. Aim: To study the prevalence of smoking among Chilean nurses. Material and methods: A cross sectional analysis of the prevalence of smoking among 290 female nurses living in 9th Region of Chile. A nicotine addiction scale was applied to smokers. Results: The prevalence of smoking was 37.9% and the percentage of former smokers was 18.3%. Twenty percent of the sample was an occasional smoker. The starting age for the habit was between 17 and 20 years (49.4%). Twenty seven percent of nurses without children and 42% of those with children smoked. Having a couple or not, did not influence the smoking habit. Ninety percent of smokers had a very low addiction to nicotine. Conclusions: The prevalence of smoking obtained in a sample of nurses is similar to that obtained by former studies in other population samples in Chile (Rev Med Chile 2003; 131: 269-74).
Avances más recientes en el desarrollo de vacunas contra la malaria

According to reports of the Pan American Health Organization, malaria transmission continues to occur in 21 countries of the Americas. Of the 835 million inhabitants of the Region of the Americas, 293 million live in areas with some possibility of transmission of the disease. The most advanced of the candidate vaccines that have been designed based on the sequences of the circumsporozoite protein, is one based on the RTS,S/AS02A polypeptides of Plasmodium falciparum. A test of that vaccine was conducted in Mozambique with children from 1 to 4 years old. The test proved the vaccine to be safe, well tolerated, and immunogenic, but the level of protection reached was still low. However, the advantages that the RTS,S/AS02A vaccine offers to people who live in malaria-endemic areas justifies its being tested in the Americas in order to evaluate its effectiveness in the clinical and epidemiological conditions specific to the Region.
QoS and fairness for CDMA packet data

Motivated by higher bandwidths and the need to handle a range of packet data services, several enhancements over the IS 95A/B packet interface have been proposed for third generation (3G) CDMA systems: enhanced physical layer to provide data rates greater than 64 kbps, enhanced MAC layer to support concurrent operation of any combination of voice, circuit and packet data, each with varying QoS and enhanced signaling to enable efficient resource management. The objective of this paper is to introduce concepts from queueing theory that address radio resource management issues for supporting packet data services over 3G CDMA systems.
PanoramaSeek: intelligent streaming for Internet video retrieval

In this paper, we present "PanoramaSeek", a new video streaming system suitable for Internet video retrieval. The system features intelligent streaming, which enables users to take quick glances at arbitrary portions of a video sequence by using slide bars. The streaming system utilizes multi-level interactive streaming and content-based selection of key frames. Multi-level interactive streaming supports three levels of display on a video window: key frame display, normal playback, and specific frame display. Users can switch between levels at any time. Content-based selection of key frames defines key frames by analyzing the changes occurring in video sequences and selecting appropriate, representative frames. Our evaluation of the system demonstrated that multi-level interactive streaming is effective in providing users with random browsing capability, and that content-based selection of key frames improves the efficiency of video retrieval by reducing the number of frames users have to check.

Efecto de la realimentación en la composición corporal de mujeres con anorexia nerviosa restrictiva; antropometría frente a impedancia bioeléctrica

Objective: To assess the body composition in a group of malnourished patients with anorexia nervosa as compared to healthy controls, before and after nutritional support, by means of anthropometry and bioimpedance. Methods: Prospective observational study. Complete anthropometry was performed as well as bioimpedance analysis in 12 women (24.5 years) with restrictive anorexia nervosa at hospital admission and weekly thereafter during re-feeding. The control group was formed by 24 healthy women (21 years). The Student’s t test, the Mann-Whitney U test, the Student’s t test for repeated measurements, and the Wilcoxon’s test were applied. The level of agreement between anthropometry and BIA was calculated by the interclass correlation coefficient and the Bland-Altman s test. Results: The patients had significant improvements in all indexes of body composition throughout their hospital staying although their values at discharge still were lower than those of the control subjects. The average weight gain was 5.22 kg (SD: 1.42), of which 51.4% was fat mass, preferentially centrally distributed. In the control subjects, the BIA equation that correlated the best with anthropometrics was Sun s equation (CCI = 0.896); in the patients, the level of agreement was weaker, both at hospital admission and at hospital discharge. Conclusions: Re-feeding produces weight gain, essentially at the expense of fat mass, which is centrally distributed; the nutritional status is not reestablished. The level of agreement between anthropometry and bioimpedance for studying body composition is acceptable, especially in healthy subjects. In those cases with severe changes in body composition and/or water balance, anthropometry is recommended when vectorial BIA or some other gold standard method are not available for the analysis of body composition.
Uses of Eye Tracking Technology in Design

Eye tracking technology has caught the attention of designers who wish to better understand how users visually interact with products and technologies. Given the availability of eye tracking technologies, which are able to measure users' eye gaze on computer screens, designers and researchers can employ eye tracking to answer a very wide variety of questions about users' visual behavior, cognition, and visual attention strategies. Yet, commercial eye tracking software typically provides a limited number of out-of-the-box analysis tools for understanding the massive amount of data generated during eye tracking sessions. This poster (1) surveys the range of questions that people have successfully asked using eye tracking technology and (2) summarizes how raw eye tracking data is transformed into higher-level constructs that are more appropriate for analysis and the kinds of analysis that can be performed. The goal of this poster is to help designers make more informed decisions when considering the use of eye tracking to aid them in design.

El Internet como fuente de información sobre la salud: la visión de estudiantes de Andalucía, España

El Internet (la red para usuarios de computadora) puede ser una herramienta útil para adolescentes y jóvenes en la búsqueda y uso de información sobre la salud. Las razones para ello han sido descritas en diversos estudios, sin embargo la confianza en la información disponible en el Internet es variable y persisten necesidades de alfabetización para su uso. Tanto el sistema de salud como el educativo pueden desempeñar un papel fundamental para el asesoramiento de la materia. Es necesario conocer las opiniones que tienen los estudiantes de educación secundaria y de universidad en Andalucía, España, sobre la relación entre el Internet y la salud, el concepto de salud y la imagen que proyecta el Internet y el ‘social media’ (medios o redes sociales electrónicos) con relación a la juventud y su salud. Hemos desarrollado un estudio, usando técnicas de etnografía virtual: hemos consultado a 55 estudiantes de enseñanza secundaria en foros virtuales y a 21 estudiantes universitarios en video entrevistas semi-estructuradas. Los estudiantes aportaron un concepto de salud integral, relacionado con los hábitos de salud física y emocional, y con los activos o factores positivos para la salud. Exponen una visión crítica de la utilidad del Internet para la salud, y sobre la calidad y credibilidad de los contenidos de salud en el Internet, manifestando la necesidad de tener asesoramiento y alfabetización. Presentan una opinión alternativa, más positiva que la visión que se da en social media e Internet sobre sus estilos de vida, y sugieren desarrollar al Internet como herramienta para potenciar la conversación participativa y el aprendizaje en salud. La metodología empleada en este estudio puede contribuir a probar nuevas formas de investigación y acción en futuros trabajos sobre la salud con adolescentes y jóvenes en Internet.
Adaptive bin sizing in Monte Carlo modeling of light transport in tissue

For high-accuracy modeling of light propagation in biological tissue, the Monte Carlo method is currently the best tool in our arsenal. Its principal drawbacks include relatively slow convergence and, in the case of 3D problems, prohibitive computer memory requirements. Furthermore, in most problems, the number of iterations required to obtain satisfactory convergence varies substantially with distance from the light source; obtaining useful information at large distances from the light source requires that we generate more data than needed at smaller distances. We will present our work on an adaptive technique, which trades off spatial resolution in regions of low light intensity against the two aforementioned drawbacks to generate an `optimal' intensity map from the available data. With this technique, memory requirements scale with the degree of detail required, and not with the physical size or dimensionality of the problem. The reduced memory requirements make 3D problems tractable, and because the technique is adaptive, a generic approach is applicable to virtually any problem, without need to tailor the program to particular geometries.
Space-time iterative MMSE multiuser detection in frequency selective coded CDMA wireless mobile channels

Iterative multiuser detection in coded CDMA uplink channels is based on the iterative exchange of soft information between a (multiuser) demodulator and a bank of single-user soft decoders to mutually benefit them. From a practical perspective, using the MMSE multiuser interference suppressor for demodulation yields good performance over a wide range of received signal powers. However, the progressively increasing correlation between estimates (with an increasing number of iterations) limits the improvement that can be obtained via further iterations, implying that the suboptimality of the MMSE demodulator plays a role in the performance levels that can be achieved. An immediate enhancement of the demodulator's performance is obtained by introducing multiple sensors at the receiver; the resulting space-time demodulator now operates on received signal mixtures with components whose spatial separation is accounted for, by virtue of their different directions of arrival. Since this separation is limited in practice, by restrictions on sensor count, array geometry, and the receiver's inability to control arrival directions, a multisensor block modulation scheme is proposed. This scheme transmits cyclically block-shifted versions of bit sequences from additional sensors using different random spreading sequences, and exploits the variation in the channel response between various transmission instances of a given bit. An iterative multiuser channel state estimator is also developed. Performance studies indicate significant reductions in the decoded bit error rate-up to that of a single user at moderately low received signal powers-and hence vastly increased spectral efficiencies.
Synchronous Control of Hyper-Chaotic System Based on Inverse-System Design

Hyper-chaotic synchronization can be applied in vast areas of physics and engineering science, and especially in secure communication. A hyper-chaotic synchronization method based on inverse-system theory is studied. The reversibility and relative degree of the synchronization error function are determined through Lie derivation calculation. A close-loop controller is obtained by synthesizing and designing a pseudo-linear feedback system, which used for estimating output variable synchronization error. Hype-chaotic synchronization of a four dimensional oscillatory system is selected as typical example and the simulation results demonstrate the validity of the method. The research results provide a useful reference for realizing hyper-chaotic synchronization.
A multi-channel optical star LAN and its application as a broadband switch

A simple optical star local area network is considered with an equal number of users and channels in the system. Optical LANs provide very high aggregate network throughputs due to concurrency achievable through wavelength division multiplexing (WDM). Using a WDM technique, multiple channels can be created in an optical fiber and a multichannel LAN can be configured using these parallel channels and a simple passive optical star coupler. The authors consider such an optical star network. Some switching protocols are developed for this LAN and its application as an integrated broadband switch, is also presented. Some of the numerical results of the throughput and delay equations for the switching protocols are presented. <<ETX>>
The Tongue and its Control by Sleep State-Dependent Modulators

The neural networks controlling vital functions such as breathing are embedded in the brain, the neural and chemical environment of which changes with state, i.e., wakefulness, non-rapid eye movement (non-REM) sleep and REM sleep, and with commonly administered drugs such as anaesthetics, sedatives and ethanol. One particular output from the state-dependent chemical brain is the focus of attention in this paper; the motor output to the muscles of the tongue, specifically the actions of state-dependent modulators acting at the hypoglossal motor pool. Determining the mechanisms underlying the modulation of the hypoglossal motor output during sleep is relevant to understanding the spectrum of increased upper airway resistance, airflow limitation, hypoventilation and airway obstructions that occur during natural and drug-influenced sleep in humans. Understanding the mechanisms underlying upper airway dysfunction in sleep-disordered breathing is also important given the large and growing prevalence of obstructive sleep apnea syndrome which constitutes a major public health problem with serious clinical, social and economic consequences.
Adaptive Routing Protocol for Reliable Sensor Network Applications

Abstract The existing routing protocol for sensor networking can be divided into proactive routing protocol, reactive routing protocol and hybrid routing protocol. Each routing protocol has its merits and shortcomings. The lifetime will end when the working routing protocol can no longer support the whole wireless sensor network. An adaptive method based on redundancy node and dual routing protocol was proposed in the study. Redundancy node, when wireless sensor network is being deployed, can divide the wireless sensor network into operating and sleeping modes, and can use the different routing protocol. Dual routing protocol individually designs two kinds of different routing protocols in the sensor node, using the merits of these two different kinds of routing protocols to accomplish the mission of sending the data. The scenario set up is when the wireless sensor network has been used for a long time; the power kept in these sensor nodes is different. It is possible that some sensor nodes contain lower power because the heavy load of work, and some with more power because of less work load. After we send a query to the source node and unfortunately find out there is more than one wireless sensor in the routing path, and if there is power shortage, we can only query a message to send the sink to the source node. At the meantime, the source node will judge the storing condition of the power in all the sensor nodes when sending the query from the sink to the source node. Then the target wireless sensor will send a broadcast to all the neighbors. If there is a sleeping node in the neighbor and run a second kind of routing protocol, the sleeping wireless sensor will wake up. The woken sensor node will build up a path to ensure the data get sent from the source to the sink. Simulation results showed that the proposed mechanism is about 44% of packet delivery ratio can be increased compared to existing proactive/reactive routing protocol.
Using Interactive Radio to Enhance Classroom Learning and Reach Schools, Classrooms, Teachers, and Learners

This article provides a case study of the development of the Open Learning Systems Education Trust's “English in Action” programme in South Africa from 1993 to the end of 2004. It describes the programme's development from a model focused on enhancing learner involvement and learner gains to a model of distance education and open learning focused on promoting teacher and learner gains through school, classroom, and teacher support, and through in‐service teacher training. It documents the expansion of schools, teachers, and learners involved in the programme over a 12‐year period. It also points out the implications and limitations of the use of radio to enhance teacher and learner involvement in open learning, in terms of the renewed interest in radio learning which has taken place over recent years in developing countries, as well as more broadly internationally.
Not measuring evolvability: initial investigation of an evolutionary robotics search space

Investigates the underlying search space of a difficult robotics problem. Previous work (P. Husbands et al., 1998) on the development of neural networks incorporating a model of gaseous neuromodulation (the GasNet) suggested that such networks are well-suited to evolutionary design for some problems. Networks that are allowed to use the gaseous signalling mechanism evolved significantly faster than networks with the mechanism disabled, implying a significant difference between the two search spaces. In this paper, we investigate this difference using a series of standard techniques for predicting the "difficulty" of searching in fitness landscapes. We show that, in this instance, measures based on random sampling do not discriminate between the two search spaces, due to the highly skewed nature of the fitness distributions, similar to those found in other difficult optimisation problems. It may be that such metrics are not useful as measures of difficulty for a class of complex problems.
