A self-healing control method for satellite attitude tracking based on simultaneous fault estimation and control design

This paper proposes a novel self-healing control method for satellite attitude tracking based on simultaneous fault estimation and control design. The proposed method integrates the fault estimation and fault-tolerant control units in a dynamic system, which is less complex and more reliable than the separately designed self-healing architectures. In this paper, the model reference approach is used to obtain a tracking error dynamic equation. Following this, an augmented error system is constructed by taking the fault as an auxiliary vector. Based on the augmented error system, a fault estimator/controller is designed to achieve robust fault-tolerant control and robust fault estimation simultaneously. The design conditions for the proposed fault estimator/controller are transformed as a set of linear matrix inequalities, which can be easily solved. Finally, numerical simulation results are given to demonstrate the effectiveness of proposed method.
Dynamics of Algorithmic Processing in Computer Systems

This paper presents a new analytical and experimental approach to the insertion sort algorithm and task processing dynamics. The dependencies that exist in the task structure can influence the algorithm’s behavior, especially in the number of dominant operations that are needed to compute the computational complexity. The proposed approach is based on a Tsallis definition of entropy suitable for all systems that are far from thermodynamical equilibrium. The ideas presented show how a complex systems approach can provide a good perspective for analyzing the processing dynamics of computer systems that are no longer simple.
Featured Article: Oxidative stress status and liver tissue defenses in diabetic rats during intensive subcutaneous insulin therapy

Long-term insulin delivery can reduce blood glucose variability in diabetic patients. In this study, its impact on oxidative stress status, inflammation, and liver injury was investigated. Diabetes was induced in Wistar rats with a single dose of streptozotocin (100 mg/kg). Untreated rats and rats administered Insuplant® (2 UI/200 g/day) through a subcutaneous osmotic pump for one or four weeks were compared with non-diabetic controls. Body weight, fructosamine level, total cholesterol, Insulin Growth Factor-1 (IGF-1) level, lipid peroxidation, and total antioxidant capacity were measured. Hepatic injury was determined through the measurement of glycogen content, reactive oxygen species (ROS) production, and macrophage infiltration. Liver oxidative stress status was evaluated through the measurement of superoxide dismutase (SOD), catalase (CAT), and nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase) expression, and p38 mitogen-activated protein kinase (p38MAPK) activation. Induction of diabetes led to increased plasma oxidative stress and inflammation. Moreover, ROS production and macrophage infiltration increased in addition to SOD, CAT, and NADPH oxidase expression. Intensive insulin therapy improved metabolic control in diabetic animals as seen by a restoration of hepatic glycogen, plasma IGF-1 levels, and a decrease in plasma oxidative stress. However, insulin treatment did not result in a decrease in acute inflammation in diabetic rats as seen by continued ROS production and macrophage infiltration in the liver, and a decrease of p38MAPK activation. These results suggest that the onset of diabetes induces liver oxidative stress and inflammation, and that subcutaneous insulin administration cannot completely reverse these changes. Targeting oxidative stress and/or inflammation in diabetic patients could be an interesting strategy to improve therapeutic options.
Robust Tracking Control of MIMO Underactuated Nonlinear Systems With Dead-Zone Band and Delayed Uncertainty Using an Adaptive Fuzzy Control

In this paper, trajectory tracking of multi-input multioutput underactuated nonlinear systems with dead-zone band and time delays is synthesized and analyzed using robust control technique based on adaptive fuzzy control. Fuzzy logic systems with online adaptations are utilized to evaluate each unknown nonlinear subsystem. It is assumed that the system includes a combined backlash and hysteresis resulting in a dead-zone band. Moreover, the gain from the delayed states and the upper bounds of the uncertainties caused by the fuzzy modeling errors are estimated online. $H_\infty$ control technique is developed to overcome the effects of the slopes of the dead-zone band and external disturbances. The stability analysis and tracking performance of the closed-loop system are verified based on the Lyapunov stability theory and Ricatti inequality, such that all the states of the system are uniformly ultimately bounded. Finally, a tower crane system is used as a case study in the simulations to validate the effectiveness and robustness of the proposed control scheme.
Teacher Education for Research‐based Practice in Expanded Roles: Finland's experience

Preparing teachers for a research‐based professionalism has been the central mission of teacher education in Finland since the mid‐1970s. More recently, as a result of such national policy developments as school‐based curriculum development and local decision‐making, the conception of teachers' work and professionalism has expanded. Drawing on experience within the teacher education programmes at the University of Helsinki and Åbo Akademi University, this paper discusses some of the programmatic issues that these developments have raised in class‐teacher, i.e. “elementary”, teacher education programmes. We focus in particular firstly on the research thesis that is a part of every teacher education programme in Finland, and the hallmark of the research‐based professional ideal; and, secondly on the emerging issues that derive from the need to incorporate the expanded understanding of the teacher's role within the curriculum of teacher education.
Interferon Gamma in Leishmaniasis

Leishmaniasis is a complex disease that is caused by parasites of the Leishmania genus. Leishmania are further classified into several complexes, each of which can engage in distinct interactions with mammalian hosts resulting in differing disease presentations. It is therefore not unexpected that host immune responses to Leishmania are variable. The induction of interferon gamma (IFN-γ) and response to it in these infections has received considerable attention. In this review, we summarize our current understanding of some of the host responses during Leishmania infections that are regulated by IFN-γ. In addition, studies that explore the nature of parasite-derived molecular mediators that might affect the host response to IFN-γ are also discussed.
Cooperative Scheduling Anti-load Balancing Algorithm for Cloud: CSAAC

In the past decade, more and more attention focuses on job scheduling strategies in a variety of scenarios. Due to the characteristics of clouds, meta-scheduling turns out to be an important scheduling pattern because it is responsible for orchestrating resources managed by independent local schedulers and bridges the gap between participating nodes. Likewise, to overcome issues such as bottleneck, overloading, under loading and impractical unique administrative management, which are normally led by conventional centralized or hierarchical schemes, the distributed scheduling scheme is emerging as a promising approach because of its capability with regards to scalability and flexibility. In this paper, we introduce a decentralized dynamic scheduling approach entitled Cooperative scheduling Anti-load balancing Algorithm for cloud (CSAAC). To validate CSAAC we used a simulator which extends the MaGateSim simulator and provides better support to energy aware scheduling algorithms. CSAAC goal is to achieve optimized scheduling performance and energy gain over the scope of overall cloud, instead of individual participating nodes. The extensive experimental evaluation with a real workload dataset shows that, when compared to the centralized scheduling scheme with Best Fit as the meta-scheduling policy, the use of CSAAC can lead to a 30%61% energy gain, and a 20%30% shorter average job execution time in a decentralized scheduling manner without requiring detailed real-time processing information from participating nodes.
Gender and managerial level differences in perceptions of effective leadership

Purpose – This paper seeks to examine gender‐ and management‐ level differences in perceptions of effective leadership within a framework of new leadership models that focus on the processes of influencing self and others rather than leadership based on hierarchy.Design/methodology/approach – A self‐report questionnaire was distributed to a sample of council employees. The responses were analysed using thematic matrix displays.Findings – Males and non‐management employees (when compared with female and management) perceived effective leadership as that which emphasises fairness, equality and honesty, develops staff, fosters workplace harmony, and is trustworthy. Female employees emphasised communication, decision‐making ability, and supporting the leader as being important to how a work unit could contribute to organizational leadership effectiveness. Employees at the management level underscored vision, supporting the leader, and integrity as being important to how a work unit could contribute to organiz.
A 14‐year‐old girl with multiple, firm, dome‐shaped eroded nodules and itching on the limbs

The standard treatment of prurigo nodularis (PN) includes antihistamines, ultraviolet light, and topical and systemic corticosteroids; unfortunately, PN is notoriously resistant to the conventional therapy. Herewith is described one case of PN, which was initialized with herose as the first‐line therapy resulting in complete clinical clearance. Results of follow‐up examinations from 2005 to 2009 showed no evidence of recurrence. Findings indicate that herose monotherapy is a potentially promising therapeutic options for PN.
The impact of arteriovenous fistulas on aortic stiffness in patients with chronic kidney disease.

BACKGROUND The creation of arteriovenous fistulas (AVF) in patients with advanced chronic kidney disease (CKD) has been shown to have adverse effects on their central pulse wave profile suggesting a likely increase in arterial stiffness. The aim of the present study was to directly evaluate the effect of AVF on arterial stiffness. Method. Thirty-one stage-5 CKD patients underwent haemodynamic assessment prior to and 3 months after creation of AVF. Haemodynamic assessment included measurement of blood pressure (BP), central and carotidal pulse wave profile analysis, and carotido-femoral and carotido-radial pulse wave velocities (PWV). Pre-AVF and post-AVF haemodynamic parameters were compared using the Wilcoxon signed-rank test or the paired Student t-test as appropriate. Pearson correlations, single and multiple linear regressions, were used to determine the association between variables. RESULTS After creation of AVF, peripheral and central BPs decreased without significant change in heart rate (HR) or pulse pressure. Carotido-femoral PWV ((c-f)PWV) fell from 13.2 +/- 4.1 to 11.7 +/- 3.1 m/s (P < 0.001). There was an increase in the central augmentation index (20.8% +/- 11.5 versus 23.7% +/- 11.6, P = 0.07) of borderline significance, and a significant reduction in the subendocardial viability ratio (153% +/- 34 versus 143% +/- 32, P < 0.05), which was mainly the result of a decrease in the diastolic pressure time index (DPTI) without any significant change in the diastolic duration. The reduction of (c-f)PWV was explained by changes in mean BP and HR (R(2) = 0.29). The reduction in DPTI was related to changes in central diastolic BP and changes in end-systolic BP (adjusted R(2) = 0.87). The significant improvement in aortic stiffness was mostly the result of the relative reduction of (c-f)PWV in the subgroup of patients with baseline (c-f)PWV above the median value of 13 m/s. CONCLUSION The creation of AVF is associated with a passive improvement of aortic stiffness especially in patients with stiffer arteries. This improvement in arterial stiffness could potentially be beneficial to the cardiovascular system despite an associated deterioration in the aortic pulse wave profile.
Coordination Imperfection Suppressed Phase Stability of Ferromagnetic, Ferroelectric, and Superconductive Nanosolids

Incorporating the recent bond order-length-strength correlation mechanism [Sun; et al. J. Phys. Chem. B 2002, 106, 10701] into the Ising premise has led to consistent insight, with an analytical expression, into the Curietemperature (Tc) suppression of ferromagnetic, ferroelectric, and superconductive nanosolids. The phase stability is related to the atomic cohesive/exchange energy that is lowered by the coordination number (CN) imperfection of the lower coordinated atoms near the surface edge. A numerical match between predictions and measurements for a number of specimens reveals that the short spin-spin correlation dominates the exchange interaction in the ferromagnetic Fe, Co, Ni, and Fe 3 O 2 nanosolids, whereas the long-range interaction dominates the exchange energy for the ferroelectric PbTiO 3 , PbZrO 3 , SrBi 2 Ta 2 O 9 , and BaTiO 3 and the superconductive MgB 2 nanosolids.

Dual-frequency dual-sense circular polarization on asymmetric crossed-dipole antenna

A novel asymmetric crossed-dipole antenna for dual - frequency dual-sense is presented. By selecting unequal lengths for the arms, the proposed antenna operates in two different frequencies, and by arranging the positions of the arms, the senses of the circular polarized (CP) radiation can be obtained arbitrarily. A prototype was fabricated and measured with left-hand circular polarization (LHCP) for the SDARS band and a right-hand circular polarization (RHCP) for the GPS band. The measurement has a good agreement with the simulation.
Regulation of adaptive immune responses by guiding cell movements in the spleen

The spleen combines the innate and adaptive immune systems in a uniquely organized way. The excision of spleen will induce many complications, especially the increased susceptibility to infections. Recent research shows that besides playing roles during the immune responses, the spleen is also an important organ during immunoregulation, which is different from other secondary lymphoid organs. This unique function is mainly realized by modulating cell migration and proliferation in the spleen. This review provides a better understanding of the functions of this complex organ gained from recent studies.
Excellent power-generating properties by using the HIT structure

We are developing HIT solar cells with high conversion efficiency, which was achieved the world's highest conversion efficiency of 22.3% in a practical size solar cell in July 2007. We have four main approaches to reducing power-generating cost: improve the conversion efficiency, apply the HIT structure to a thin wafer, improve the temperature coefficient, and apply HIT solar cells to a bifacial solar module. Using these approaches, we have achieved the remarkably high conversion efficiency of 21.4% due to a high Voc of 0.739 V with an 85-μm cell, which was measured at SANYO. A thinner Si wafer brings not only high Voc but also generating more output power at high temperature for a better temperature coefficient. We have confirmed that the HIT structure is suitable for use in thinner wafers, allowing us to reduce power-generating cost.
The Antibacterial Activity of Honey

Ergo is traditional Ethiopian fermented milk produced by spontaneous fermentation using traditional utensils under non-hygienic environment. To produce microbiologically safe and chemically defined product; study on the production, processing, utilization and handling of Ergo under different agro-ecological zones as well as the isolation and characterization of potential lactic acid bacteria strains with the potential production of inhibitory factor should be the first essential step. Even though milk is fermented and consumed in all these areas a very limited hygienic care is practiced, 93.4% of the households do not heed for the sanitary aspect of the milk and milk products. To evaluate the antimicrobial activity of the lactic acid bacteria (LAB), 112 strains of LAB, belonging to Lactococcus, Lactobacillus, Entorococcus, Streptococcus, Leuconostoc and Pediococcus were isolated from Ethiopian traditional fermented milk, Ergo . Moreover the culture filtrates of all the isolates were examined for antimicrobial activity on some food borne pathogens Salmonella thyphi, Shigella flexineri , Staphylococcus aures (ATCC-25923) and Escherchia coli (ATCC-25922) using disc diffusion assay method. Twelve strains of lactic acid bacteria that produced the greatest antimicrobial substance were selected. These strains were identified as species of Lactobacillus acidophilus(2) , Lactobacillus plantarum(2), Lactococcus lactic spp crimoris(2) , Lactococcus lactic spp lactic(3), Leuconostoc lactic (1) , Pediococcus pentosaceus(1) and Pediococcus sp. (1). All the inhibitory substance-producing strains were tested for their temperature and pH stability. The antimicrobial activity of the culture filtrate of isolated strains were completely inactivated when treated at 121oC for 15 minutes, whereas at 30, 60 and 80oC there were no Significant (P>0.05) difference in diameter of inhibition compared to untreated (control). The entire culture filtrate were stable with in a wide range of pH (2-10) and no significant (P>0.05) difference was observed between the treated filtrate and the untreated (control). However treating the culture filtrate at pH 12 has significantly (P<0.05) decreased the inhibition diameter.
Inappropriate prescribing in the elderly

Background and objective: Drug therapy is necessary to treat acute illness, maintain current health and prevent further decline. However, optimizing drug therapy for older patients is challenging and sometimes, drug therapy can do more harm than good. Drug utilization review tools can highlight instances of potentially inappropriate prescribing to those involved in elderly pharmacotherapy, i.e. doctors, nurses and pharmacists. We aim to provide a review of the literature on potentially inappropriate prescribing in the elderly and also to review the explicit criteria that have been designed to detect potentially inappropriate prescribing in the elderly.
Endocardial Segmentation in Contrast Echocardiography Video with Density Based Spatio-Temporal Clustering

We present a spatio-temporal clustering algorithm for detection of endocardial contours in short axis (SAX) contrast echocardiographic image sequences. A semiautomatic method for segmentation of left ventricle in SAX videos is proposed which uses this algorithm and at the same time requires minimal expert intervention. Expert is required to specify a few candidate points belonging to the contour, only in the first frame of the sequence. The initial contour is approximated by fitting an ellipse in the region defined by the points specified. This region is identified as the principal cluster corresponding to the left ventriclular cavity. Later the density based clustering was applied for regularization on the inital contour. We have extended the DBSCAN algorithm for identification of the principal cluster corresponding to the left ventricle from the image. The algorithm also incorporates the temporal information from the adjacent frames during the segmentation process. The algorithm developed was applied to 10 data sets over full cardiac cycle and the results were validated by comparing computer generated boundaries to those manually outlined by one expert. The maximum error in the contours detected was ±2.9mm. The spatio-temporal clustering algorithm proposed in this paper offers an efficient semiautomatic segmentation of heart chambers in 2D contrast echocardiography sequences.
