Robust Adaptive Output Tracking for Quadrotor Helicopters

Quadrotor helicopters are drawing considerable attention both for their mobility and their potential to perform multiple tasks in complete autonomy. Moreover, the numerous limitations characterizing these aircraft, such as their underactuation, make quadrotors ideal testbeds for innovative theoretical approaches to the problem of controlling autonomous mechanical systems. In this chapter, we propose a robust model reference adaptive control architecture and design an autopilot for quadrotors, which guarantees satisfactory output tracking despite uncertainties in the vehicle’s mass, matrix of inertia, and location of the center of mass. The feasibility of our results is supported by a detailed analysis of the quadrotor’s equations of motion. Specifically, considering the vehicle’s equations of motion as a time-varying nonlinear dynamical system and avoiding the common assumption that the vehicle’s Euler angles are small at all times, we prove that the proposed autopilot guarantees satisfactory output tracking and verifies sufficient conditions for a weak form of controllability of the closed-loop system known as strong accessibility. A numerical example illustrates the applicability of the theoretical results presented and clearly shows how the proposed autopilot outperforms in strong wind conditions autopilots designed using a commonly employed proportional-derivative control law and a conventional model reference adaptive control law.

EXPERIMENTAL INVESTIGATION OF COORDINATION AT AGGREGATE VERSUS INDIVIDUAL LEVEL

We argue that the ability to coordinate under strategic complementarity is substantially affected by mutual interactive development at the individual and aggregate level. Optimal strategy which is followed by each player does not only depend upon strategy of the other player but also on conditions prevailed at the aggregate level. Results of our laboratory experiment suggest that certain type of player might be or might be not awarded depending on type of the economy, which has important implications at the aggregate level with respect to the speed of the convergence.
Thirty-Two Sample Audio Search Tasks

Searching in audio archives is potentially very useful, and good evaluations can guide development to realize that promise. However most current evaluation programs are technology-centric, rather than user-oriented and task-centric. This paper examines current and potential audio search needs and scenarios, and presents a sample set of thirty-two diverse audio search tasks to support more realistic evaluations.
In Vitro Shoot Multiplication of Two Sugarcane (Saccharum officinarum L.) Genotypes using Shoot Apical Meristem

Conventional propagation of sugarcane (Saccharum officinarum L.) is limited due to low propagation rates, its time demand and potential transmission of pathogens through seed cane from generation to generation. In vitro propagation is the best alternative to overcome such limitations of conventional propagation. Hence, this study was initiated to optimize a protocol for rapid in vitro multiplication of two sugarcane genotypes (B4906 and Pr1013) grown in Ethiopia. This experiment was carried out in completely randomized design (CRD) with 2x5x5 factorial treatments arrangement of genotypes, BAP (0.5, 1.0, 1.5, 2.0, and 2.5 mgl -1 ) and NAA (0, 0.2, 0.3 0.4, and 0.5 mgl -1 ) in combination. Analysis of variance revealed that the interaction effects of genotypes, BAP and NAA were very highly significant (p< 0.001) for number of shoots/explant, shoot length and leaves/shoot. On MS media with 1.5mgl -1 BAP and 0.4mgl -1 NAA, B4906 gave the highest (16.88±0.5) numbers of shoots with 5.94±0.17 cm shoot length and 6.33±0.29 leaves/shoot. Whereas 2mgl -1 BAP and 0.5mgl -1 NAA resulted in a maximum of 11.70±0.28 shoots with 4.48±0.08 cm shoot length and 4.95±0.11 leaves/shoot for Pr1013. It could be concluded that the optimized protocol is useful for rapid clonal multiplication of sugarcane planting materials. Keywords : apical meristem, BAP, multiplication, NAA
Employment Recommendation System: A Review

: Enormous amounts of jobs are posted on the job websites on daily basis and large numbers of new resumes are also added to job websites daily. In such scenario it‟s a very tough job to suggest matching jobs to the job applicants. A recommendation system can solve this problem to the great extent. A recommendation system has already been proved to be very effective in the area of Online shopping websites and Movie recommendation. Given a user, the goal of an employment recommendation system is to predict those job positions that are likely to be relevant to the user. An Employment recommendation system would suggest matching jobs to the users using matching, collaborative filtering and content based recommendation based on ranking.
TEMPORAL DYNAMICS AND COMMUNICATION OF WINNER-EFFECTS IN THE CRAYFISH, ORCONECTES RUSTICUS

A variety of factors influences the formation of hierarchical structures, and can include an altered aggressive state, an ability to physically dominate, and previous agonistic experience. Using male Orconectes rusticus, we tested the duration of the winner effect by varying the time between a winning encounter and a subsequent encounter by a 20, 40 or 60-minute interval. Varying the time between the two fights significantly altered the probabilities of initiating fight behaviour and of winning a fight. A crayfish with a 20-minute delay between its winning experience and its subsequent fight was significantly less likely to initiate fight behaviour and significantly more likely to win its next fight than was an animal whose next fight was delayed for 40 or 60 minutes. We then investigated whether the dynamics of this winner effect were influenced by perception of odour signals during agonistic interactions by blocking the chemo- and mechanoreceptors on the antennae and antennules to prevent reception of relevant cues communicating social status. Individuals fighting an opponent with this loss of sensory information were significantly more likely to initiate a fight, but then escalated at a slower rate to a higher fight intensity level. In addition, individuals had a decreased chance of winning an agonistic bout against an opponent deprived of sensory input from the antennae and antennules.
In vitro Gas Production and Fermentative Characteristics of Cottonseed and Cottonseed By-products

A study was conducted to evaluate the in vitro gas production and post-incubation parameters of cotton seed ( Gossypium spp ) and cotton seed by-products. Cotton seed was processed into four different sample types regarded as treatments i.e. raw cotton seed(A), parboiled cotton seed (B), roasted (C) and cotton seed cake (D). All the chemical constituents investigated were all similar for all treatments (p>0.05). Highest DM (90.07% DM) and CP (24.72% DM) results were obtained from cottonseed cake (D). In vitro gas production characteristics of cotton seed and cotton seed by-products were determined at 24hrs of incubation. The gas production results were significantly different (p<0.05) in all the cottonseed by-products. The result revealed after 24hrs, that cotton seed cake had the highest value of in vitro gas production from soluble and insoluble fraction, potential extent gas production as well as the volume of gas produced at incubation time. It can be concluded from the chemical constituent findings of this research, that cottonseed cake had highest crude protein and digestibility (or possess good fibre content) when compared to feeds consisting of other cottonseed by-products.

The SSVEP-Based BCI Text Input System Using Entropy Encoding Algorithm

The so-called amyotrophic lateral sclerosis (ALS) or motor neuron disease (MND) is a neurodegenerative disease with various causes. It is characterized by muscle spasticity, rapidly progressive weakness due to muscle atrophy, and difficulty in speaking, swallowing, and breathing. The severe disabled always have a common problem that is about communication except physical malfunctions. The steady-state visually evoked potential based brain computer interfaces (BCI), which apply visual stimulus, are very suitable to play the role of communication interface for patients with neuromuscular impairments. In this study, the entropy encoding algorithm is proposed to encode the letters of multilevel selection interface for BCI text input systems. According to the appearance frequency of each letter, the entropy encoding algorithm is proposed to construct a variable-length tree for the letter arrangement of multilevel selection interface. Then, the Gaussian mixture models are applied to recognize electrical activity of the brain. According to the recognition results, the multilevel selection interface guides the subject to spell and type the words. The experimental results showed that the proposed approach outperforms the baseline system, which does not consider the appearance frequency of each letter. Hence, the proposed approach is able to ease text input interface for patients with neuromuscular impairments.
Computación y Sistemas, Vol. 18, No. 4, 2014

In some fields like forensic research, experts demand that a found sample of an individual can be matched with its full counterpart contained in a database. The found sample may present several characteristics that make this matching more difficult to perform, such as distortion and, most importantly, a very small size. Several solutions have been presented intending to solve this problem, however, big computational effort is required or low recognition rate is obtained. In this paper, we present a fast, simple, and efficient method to relate a small sample of a partial palmprint to a full one using elemental optimization processes and a voting mechanic. Experimentation shows that our method performs with a higher recognition rate than the state of the art method, when trying to identify palmprint samples with a radius as small as 2.64 cm.
Spatial tree age structure and fire history in two old-growth forests in eastern Fennoscandia

Two near natural old-growth forests, one dominated by Picea abies and the other by Pinus sylvestris, were studied for their fi re history, and spatial patterns of trees and tree ages. The spatial tree age structure and the disturbance history of the forests were examined by drawing age class maps based on mapped and aged trees and by dating fi res based on fi re scars, and by using spatial analyses at tree scale. The tree age structures of the Picea and Pinus dominated forests were different, mainly due to differences in fi re history and sensitivity of the dominant tree species to fi re. Fire histories and tree age structures of both sites have probably been affected by human in the ancient past. However, in the Picea dominated site, the fi res had been severe, killing most of the trees, whereas in the Pinus dominated site the severity of fi res had been more variable, leaving some Pinus and even Picea trees alive. In the Pinus dominated site, the tree age distribution was multimodal, consisting of two Pinus cohorts, which were established after fi res and a later Picea regeneration. The Picea dominated site was composed of four patches of different disturbance history. In the oldest patch, the tree age distribution was unimodal, with no distinct cohorts, while a single cohort that regenerated after severe fi re disturbances dominated the three other patches. In both sites the overall spatial patterns of living and dead trees were random and the proportion of spatially autocorrelated variance of tree age was low. This means that trees of different age grew more or less mixed in the forest without forming spatially distinct regeneration patches, even in the oldest patch of Picea dominated Liimatanvaara, well over 200 years after a fi re. The results show that detail knowledge of disturbance history is essential for understanding the development of tree age structures and their spatial patterns.
The Generalized Chebyshev Substrate Integrated Waveguide Diplexer

A new generalized chebyshev substrate integrated waveg- uide diplexer is presented for high performance. The diplexer is de- signed with triplet topology based on substrate integrated waveguide technique, which exhibit the generalized chebyshev responses. The triplet topology can facilitate the resonator arrangements of diplexer design for compact size. This diplexer possesses of the advantages of SIW and the generalized chebyshev filters. All couplings, including the negative coupling, are realized by H-plane open windows. A diplexer is designed by using 3th order asymmetric generalized chebyshev filter. Measured results are good agreement with simulation results.
A model for triggering mechanisms of shallow landslides

Abstract. Rainfall-induced shallow landslides, also called "soil slips", are becoming ever more frequent all over the world and are receiving a rising interest in consequence of the heavy damage they produce. At the University of Parma, a simplified physically based model has been recently set up for the evaluation of the safety factor of slopes which are potentially at risk of a soil slip. This model, based on the limit equilibrium method applied to an infinite slope, takes into account some simplified hypotheses on the water down-flow and defines a direct correlation between the safety factor of the slope and the rainfall depth. In this paper, this model is explained in detail and is used in a back analysis process to verify its capability to foresee the triggering instant of rainfall-induced shallow landslides for some recent case studies in the Emilia Romagna Apennines (Northern Italy). The results of the analyses and of the model implementation are finally shown.
Physical ability in bariatric surgery patients : results of the supervised and individual approach

Introduction: Physical activity (PA), exercise, and lifestyle intervention are basic interventions to reduce shortand long-term surgical and non-surgical complications in bariatric patients. The purpose of our study was, first, to evaluate the importance of individualized, professionally guided training, encouraging PA, and subsequent positive effects of physical ability and body composition following a structured and supervised exercise program. Methods: A total of 11 morbidly obese male (n = 4) and female (n = 7), aged 30–54 years, previously subjected to bariatric surgery, were recruited and subjected to 10-weeks structured and supervised exercise protocol with nutritional counseling and motivational support, consisting of twice weekly aquatic and outdoors training sessions. The same protocol was applied to the control group but without supervision, counseling and support. Blood analyses, basic anthropometric measures, body composition analyses, and physical fitness tests were performed before and after the exercise protocol. Results: The weight, body fat, BMI, systolic and diastolic pressures were mildly decreased after the exercise program, while sit-to-stand, handgrip, and one leg stance scores showed mild increase after the exercise program. Conclusion: Obese bariatric surgery patients may benefit from structured, supervised exercise program with nutritional counseling and motivational support. Further studies with larger number of participants are needed to confirm the results.
The effects of antiretroviral treatment on liver function enzymes among HIV-infected out patients attending the Central Hospital of Yaounde, Cameroon

The emergence of liver diseases as one of the major causes of death in people infected with HIV has paralleled the introduction of more effective antiretroviral therapies. This study was carried out with the aim of determining the effects of antiretroviral treatment on liver enzymes (SGOT and SGPT) in patients placed on antiretroviral therapy. A prospective cross-sectional 3 years study was carried out among patients confirmed to be HIV positive and who were to be placed on antiretroviral drugs at the HIV/AIDS out patient clinic of the Yaounde Central Hospital, . Cameroon. Levels of transaminases of patients were measured in four phases using the International Federation of Clinical Chemistry (IFCC) protocol. Of the 150 patients who participated in the study, 54.0 %( 81/150) presented with transaminitis at the final phase of the study with respect to aspartate aminotransferase (AST), 77.78% (63/81) of whose AST levels only increased after initiation of highly active antiretroviral therapy (HAART). 22.67% (34/150) presented with transaminitis with respect to alanine aminotransferase (ALT). At the final phase, 70.58% of whose ALT levels only increased after HAART initiation. Increase in blood transaminase levels was statistically independent on age group and the drug combinations. Increase in AST levels was associated with an increase in ALT levels upon treatment (r = 0.58). There was a significant positive linear relationship between duration of treatment and concentration of transaminases over the years (r= 0.9). We therefore concluded that highly active antiretroviral therapy (HAART) is associated with low level hepatotoxicity at therapy initiation, regardless of drug class or combination.

How do Macroeconomic Changes Impact Islamic and Conventional Equity Prices? Evidence from Developed and Emerging Countries

In theory, the price of equity is determined by the dividend yields and growth potentials of the firms. There exists established empirical proof of the impact of macroeconomic changes to the equity markets. With the advent of Islamic equities, and the recent surge of interest in them have raised the question of whether the same theoretical framework and relationship be considered for Shariah compliant equities or not. This study explores the impact of macroeconomic changes on Islamic and conventional indices for a large set of 37 countries, classifying them according to developed and emerging countries. The study finds a higher impact of Industrial production on the Islamic equities, while the interest rate and money supply have a lesser impact as compared to the impact on conventional counterparts. This lends support to the argument that Shariah screening methodology provides a set of Islamic equities which are more founded on the real sector of the economy. In addition the adjustment process during the crisis is faster for the Islamic equities in both regions. These results provide initial empirical proof for further research on the impact of specific economic variables on the changes in Islamic equity prices.
Parameter Selection Method for Support Vector Regression Based on Adaptive Fusion of the Mixed Kernel Function

Support vector regression algorithm is widely used in fault diagnosis of rolling bearing. A new model parameter selection method for support vector regression based on adaptive fusion of the mixed kernel function is proposed in this paper. We choose the mixed kernel function as the kernel function of support vector regression. The mixed kernel function of the fusion coefficients, kernel function parameters, and regression parameters are combined together as the parameters of the state vector. Thus, the model selection problem is transformed into a nonlinear system state estimation problem. We use a 5th-degree cubature Kalman filter to estimate the parameters. In this way, we realize the adaptive selection of mixed kernel function weighted coefficients and the kernel parameters, the regression parameters. Compared with a single kernel function, unscented Kalman filter (UKF) support vector regression algorithms, and genetic algorithms, the decision regression function obtained by the proposed method has better generalization ability and higher prediction accuracy.
Relation of Physical Activity and Health-related Quality of Life in Korean Elderly

AbstractThis study aims to discover the relations between physical activities of the elderly and their health-related quality of life. For the study, it targeted 720 of the 778 elderly persons whose ages were above 65 for a final analysis except 58 whose physical activities and health-related quality of life could not be evaluated from the data of the first year of the 4th Korea National Health and Nutrition Examination Survey(KNHANES Ⅳ-1), 2007.As a result, it was discovered that there were significant differences in the elderly's health-related quality of life according to age, education, sleeping hours, stress, the number of chronic diseases and subjective awareness of health. In particular, there were significant differences in their health-related quality of life between the group with high physical activity level and the group with low physical activity level. Based on the results above, it is suggested that the persons with higher performance ability of physical activities can have higher quality of living along with increase of energy and further studies dealing with more factors, ranges and periods are needed.
Comparative Evaluation of the Pathloss Prediction Performance Hata-Okumura Pathloss Model for Urban, Suburban and Rural Areas

In this paper, comparative evaluation of the pathloss prediction performance of the popular Hata-Okumura model for urban, suburban and rural areas is carried out. The study is based on empirical measurements conducted at Imo state university campus for 800 MHz GSM network. The prediction performance of the three categories of the Hata-Okumura model is analyzed and compared in terms of Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and Prediction Accuracy (PA). The results showed that the Hata-Okumura model for the Urban area has the best prediction accuracy when not optimised but it has the lowest optimised prediction accuracy. On the other hand the Hata-Okumura model for the rural/open area has the least prediction accuracy when not optimised but it has the highest prediction accuracy when it is optimised. The results show that adoption of a model because it has the highest prediction accuracy is not the best approach to the selection of pathloss models. Rather the models should be optimised and the best optimised model should be adopted.
