Application of a feedforward controller with a disturbance observer for UAV during missile launch

This paper presents a feedforward controller with disturbance observer for UAV (unmanned aerial vehicle), which is able to reduce the disturbance produced by launching missile from UAV. The focus of this work was in two areas. First, according to the layout characteristics of UAV platform, the aerodynamic interference between UAV and external stores was analyzed, and the flight stability and control performance during two ways of external separation were simulated by establishing six degree-of-freedom dynamics and kinematics equations of UAV. Second, the control law was designed by blending the feedforward controller and disturbance observer into the flight control system. The simulation results show that the stability and anti-interference ability of UAV are improved during the missile launch.
By Choice or by Chance: How the Internet Is Used to Prepare for, Manage, and Share Information about Emergencies

Access to reliable information is essential for emergency managers, whether they're facing tornados or terrorist attacks. How well information is managed before, during, and after a disaster can have a direct influence on how well the crisis is managed. Today the Internet plays a recurring role in all phases of emergency information management. As a communication system and an information repository, a strategic tool and a populist medium, the Internet can be a powerful element in crisis situations. It has been readily used in recent crises and it will, no doubt, be used in the next emergency, by choice or by chance. The choice must be made to use it well. This article explores the implications of the Internet for agencies that work to mitigate, prepare for, and respond to natural and human-made disasters. It also looks at implications of the Internet for members of the general public who are directly or indirectly affected by disasters.
A study on beam tilt angle of base station antennas for Base Station Cooperation systems

Base Station Cooperation (BSC) is one of the key technologies for next generation cellular systems. The BSC can improve channel capacity at the cell-edge unlike conventional single cell transmission. In this paper, we will study about beam tilt angle of base station antennas for the BSC systems. In conventional systems, beam tilt angle is designed to maximize the power of its own cell while minimizing the power from adjacent cells to reduce Inter-Cell Interference (ICI). Unfortunately, performance at the cell-edge cannot be improved since Signal-to-Interference Ratio (SIR) is unchanged regardless of the beam tilt angle. However, since the problem of ICI is removed in the BSC system, beam tilt angle is required to be designed differently from the conventional way. In this paper, we will derive optimal beam tilt angle for the BSC systems based on these considerations. For that purpose, an objective function to maximize average channel capacity of cooperative cell is defined, and the optimal beam tilt angle is derived by solving the problem. By numerical analysis, it is shown that the optimal beam tilt angle for the BSC system is smaller than that of the single cell transmission. By using the optimal base station antennas, channel capacity of the BSC system is greatly improved, especially at the cell-edge.
Domestic Violence in Arab Society: A Comparison of Arab and Jewish Women in Shelters in Israel

The aim of the current study was to address a gap in the literature by determining prevalence, specific types of violence, and risk factors of intimate partner violence (IPV) among Israeli born Arab women compared with Israeli born Jewish women. The following measures were compared: demographic and socioeconomic measures; measures relating to the characteristics of the violence, that is, the three types of violence (physical, emotional, and verbally threatening), sense of danger, and history of violence in childhood; family support levels; and perpetrator characteristics. The sample consisted of 154 Israeli born Arab women and 149 Israeli born Jewish women who were staying in shelters for victims of domestic violence in Israel. A comparison of the two groups revealed that the Arab women were exposed to more physical violence and received less family support than did their Jewish counterparts. The proportion of Arab perpetrators with access to weapons was higher than that of Jewish perpetrators, whereas the proportion of police complaints against Jewish perpetrators was higher than that against Arab perpetrators. Arab women were also younger, less educated, and less a part of the workforce than Jewish women. The contribution of the woman’s age to the variance in levels of physical violence was negative and significant. In contrast, the contribution of her sense of danger, and various perpetrator characteristics, was positive. Moreover, the interaction between sense of danger × ethnicity contributed significantly to levels of violence. This study extends the existing knowledge about the contribution of ethnicity as one of many variables that play a role in the lives of women who are victims of domestic violence and highlights the need to develop, in particular, unique individual, community, and social interventions for Arab women in Israeli society.
Category Learning Through Multimodality Sensing

Humans and other animals learn to form complex categories without receiving a target output, or teaching signal, with each input pattern. In contrast, most computer algorithms that emulate such performance assume the brain is provided with the correct output at the neuronal level or require grossly unphysiological methods of information propagation. Natural environments do not contain explicit labeling signals, but they do contain important information in the form of temporal correlations between sensations to different sensory modalities, and humans are affected by this correlational structure (Howells, 1944; McGurk & MacDonald, 1976; MacDonald & McGurk, 1978; Zellner & Kautz, 1990; Durgin & Proffitt, 1996). In this article we describe a simple, unsupervised neural network algorithm that also uses this natural structure. Using only the co-occurring patterns of lip motion and sound signals from a human speaker, the network learns separate visual and auditory speech classifiers that perform comparably to supervised networks.
New Method for Phosphate Kinetics Estimation during Hemodialysis and On-Line Hemodiafiltration with Endogenous Reinfusion

Aim: The purpose of this study was to optimize the operative and analytical methodologies to a more exact determination of intradialytic kinetics of the phosphates (P) tested in hemodialysis (HD) and in on-line hemodiafiltration with endogenous reinfusion (HFR – Hemo Filtrate Reinfusion). Methods: The mass balance measurements of urea and P were carried out in 18 clinically stable HD patients. The effective blood flow (Qb) was measured with a Transonic® monitor. The plasma was deproteinized with 10% trichloroacetic acid to prevent breakdown of the proteins and the consequent pseudohyperphosphatemia. Subsequently the supernatant containing the ultrafiltrable phosphates was made to react with a solution of ammonium molybdate for a spectrophotometric reading. Results: The mean urea mass transfer in HD was 16.9 g/session and in HFR 15.4 g/session. The mean P mass transfer in HD was 726 mg/session and in HFR 679 mg/session. Nevertheless, in HFR a significant difference was verified between the clearances of P, between the plasma water side (122.4 ± 30.8 ml/min) and the dialysate side (105.9 ± 19.4 ml/min). Conclusion: As far as the P mass transfer is concerned, the data obtained is able to be superimposed with that described in the literature during HD, while in HFR it is possible to hypothesize a high efficiency, thanks to an increased output of P in relation to the phenomenon of adsorption which, although is limited, contributes to the transfer of the total mass. Based on this study and re-examining the literature on P kinetics, there is space for methodological improvement both on the operating front with careful determination of the effective Qb, and on the chemical front overcoming the inaccuracy of automatic analyzers in determining the plasma P owing to possible overestimation of phosphatemia and poor sensitivity in measuring the lower levels of P present in the dialysate and/or ultrafiltrate.
Microalbuminuria reflects a generalized transvascular albumin leakiness in clinically healthy subjects.

1. In epidemiological studies microalbuminuria, i.e. slightly elevated urinary albumin excretion rate, predicts increased atherosclerotic vascular morbidity and mortality. This study aimed to test the hypothesis that microalbuminuria in clinically healthy subjects is associated with a systemic transvascular albumin leakiness. In animal experiments the outflux of albumin and lipids to the arterial wall are highly correlated, and both are elevated in atherosclerosis. 2. All participants were recruited at random from a population-based epidemiological study, where the upper decile of urinary albumin excretion rate was 6.6 micrograms/min. Twenty-seven patients with persistent microalbuminuria (urinary albumin excretion rate 6.6-150 micrograms/min), and 56 age- and sex-matched control subjects with persistent normoalbuminuria (UAER < or = 6.6 micrograms/min) were studied. 3. The systemic transvascular albumin leakage was measured as the fractional disappearance rate of 125I-labelled albumin from the total plasma compartment in 1 h after intravenous injection. 4. The fractional disappearance rate of albumin from the plasma compartment was higher in the microalbuminuric than in the normoalbuminuric group [5.8 (95% confidence interval 5.3-6.2; n = 27) versus 5.0 (4.6-5.5; n = 56)%/h, P < 0.05]. The positive correlation between urinary albumin excretion rate on continuous scale (logarithmically transformed) and the fractional disappearance rate of albumin from the plasma compartment [slope 0.4 (95% confidence interval 0.1-0.7; n = 83), r = 0.29, P < 0.005] was independent of age, sex, smoking status, blood pressure, body size, plasma volume, plasma albumin concentration and concentrations of blood glucose, serum insulin and serum lipids. 5. In conclusion, microalbuminuria is an independent marker of systemic transvascular albumin leakiness in clinically healthy subjects. (ABSTRACT TRUNCATED AT 250 WORDS)
BMCLua: Verification of Lua programs in digital TV interactive applications

The present paper describes a novel scheme for checking for potential defects in Lua programs, by using Bounded Model Checking (BMC). Such an approach, called BMCLua, translates a Lua program into an ANSI-C one, which is then verified by the Efficient SMT-Based Bounded Model Checker (ESBMC). BMCLua is able to check for safety properties related to array bounds, division by zero, and user-specified assertions, in Lua programs. This paper marks the first application of BMC to Lua programs. The experimental results show that the performance of BMCLua is similar to that of ESBMC, in about 70% of the benchmarks used for evaluation.
Study on traffic classification taxonomy for multilateral and hierarchical traffic classification

Internet traffic has rapidly increased due to the increasing use of wireless devices and the appearance of various applications and services. With the rapid increase of Internet traffic, the need for Internet traffic classification becomes important for the effective use of network resources. However, the traffic classification taxonomy has received little attention compared to the study of classification methods. In this paper, we propose novel traffic classification taxonomy for multilateral and hierarchical traffic identification. The proposed taxonomy can support multilateral identification based on the proposed four classification criteria: service, application, protocol, and function. In addition, the proposed taxonomy can support hierarchical structure supporting roll-up and drill-down operation to the classification result. We proved the applicability and advantages of the proposed taxonomy by applying it to real campus network traffic.

Content addressable memory (CAM) is an essential component of high-end network processing systems. In this paper, a novel CAM cell is presented. By simply setting the control signal onto the cell, it can be configured as either the binary or ternary CAM. Simulations on a 64-bit CAM test circuit using 0.13 mum process have been carried out. The functionality, timing and power performance of proposed CAM array are discussed.
A low voltage VGA for RFID receivers

RFID is a worldwide attractive technology for reliable wireless communication system. Automatic gain control system of such devices is very important which is performed by Variable Gain Amplifier (VGA). In this paper, a class AB VGA, consisting of a linear transconductor amplifier and a linear transimpedance amplifier, is designed and simulated in CEDEC (software for design and simulation of ICs) 0.18-μm CMOS process for low power and high speed RFID receivers. The simulation result show that, the proposed VGA has a wide bandwidth of 100 MHz and dissipates power less than 125 uW at 1 V supply voltage. From the results it is also apparent that the circuit is capable of working with high linearity and wide bandwidth. Good frequency response (Gain) and the wide bandwidth of this class AB VGA makes it suitable for low power RFID receiver transceivers.
A novel 2 GHz multi-layer AMBA high-speed bus interconnect matrix for SoC platforms

The paper proposes a novel multi-layer AMBA high-speed bus (AHB) infrastructure designed to sustain a clock frequency of more than 2 GHz, which remarkably provides up to 4 giga data transfers per second of throughput. The interconnect matrix is achieved through a collection of high-performance bridges that serialize transfers toward a high-throughput shared-memory. As a result, we guarantee a maximum of one cycle communication latency to sixteen 125 MHz processors connected to our infrastructure. The proposed solution has been designed and verified with Cadence tools using a 0.18 /spl mu/m CMOS technology.
Therapeutical Administration of Peptide Pep19-2.5 and Ibuprofen Reduces Inflammation and Prevents Lethal Sepsis

Sepsis is still a major cause of death and many efforts have been made to improve the physical condition of sepsis patients and to reduce the high mortality rate associated with this disease. While achievements were implemented in the intensive care treatment, all attempts within the field of novel therapeutics have failed. As a consequence new medications and improved patient stratification as well as a thoughtful management of the support therapies are urgently needed. In this study, we investigated the simultaneous administration of ibuprofen as a commonly used nonsteroidal anti-inflammatory drug (NSAID) and Pep19-2.5 (Aspidasept), a newly developed antimicrobial peptide. Here, we show a synergistic therapeutic effect of combined Pep19-2.5-ibuprofen treatment in an endotoxemia mouse model of sepsis. In vivo protection correlates with a reduction in plasma levels of both tumor necrosis factor α and prostaglandin E, as a likely consequence of Pep19-2.5 and ibuprofen-dependent blockade of TLR4 and COX pro-inflammatory cascades, respectively. This finding is further characterised and confirmed in a transcriptome analysis of LPS-stimulated human monocytes. The transcriptome analyses showed that Pep19-2.5 and ibuprofen exerted a synergistic global effect both on the number of regulated genes as well as on associated gene ontology and pathway expression. Overall, ibuprofen potentiated the anti-inflammatory activity of Pep19-2.5 both in vivo and in vitro, suggesting that NSAIDs could be useful to supplement future anti-sepsis therapies.
Limitation of myocardial infarction by early infusion of recombinant tissue-type plasminogen activator.

In a double-blind randomized trial involving five Sydney hospitals and the city ambulance paramedical service, 145 patients with a first evolving myocardial infarction and with onset of pain less than 2.5 (mean 1.9 +/- 0.5 [SD]) hr previously were allocated to intravenous infusion of 100 mg recombinant tissue-type plasminogen activator (rt-PA) or placebo over 3 hr. The groups at entry were similar. At assessment 21 days later, left ventricular ejection fraction measured both by contrast and radionuclide ventriculography was higher in the rt-PA compared with the placebo group (61 +/- 13%, n = 64, vs 54 +/- 14%, n = 62, contrast, 2p = .006; 52 +/- 13%, n = 66, vs 48 +/- 13%, n = 62 isotope, 2p = .08). This indicates limitation of myocardial infarction by rt-PA.
Waist Circumference and Body Mass Index as Predictors of Health Care Costs

Background In the present study we analyze the relationship between body mass index (BMI) and waist circumference (WC) and future health care costs. On the basis of the relation between these anthropometric measures and mortality, we hypothesized that for all levels of BMI increased WC implies added future health care costs (Hypothesis 1) and for given levels of WC increased BMI entails reduced future health care costs (Hypothesis 2). We furthermore assessed whether a combination of the two measures predicts health care costs better than either individual measure. Research Methodology/Principal Findings Data were obtained from the Danish prospective cohort study Diet, Cancer and Health. The population includes 15,334 men and 16,506 women 50 to 64 years old recruited in 1996 to 1997. The relationship between future health care costs and BMI and WC in combination was analyzed by use of categorized and continuous analyses. The analysis confirms Hypothesis 1, reflecting that an increased level of abdominal fat for a given BMI gives higher health care costs. Hypothesis 2, that BMI had a protective effect for a given WC, was only confirmed in the continuous analysis and for a subgroup of women (BMI<30 kg/m2 and WC <88 cm). The relative magnitude of the estimates supports that the regressions including WC as an explanatory factor provide the best fit to the data. Conclusion The study showed that WC for given levels of BMI predicts increased health costs, whereas BMI for given WC did not predict health costs except for a lower cost in non-obese women with normal WC. Combining WC and BMI does not give a better prediction of costs than WC alone.

A Stable On-line Algorithm for Energy Efficient Multi-user Scheduling

In this paper, we consider the problem of energy efficient uplink scheduling with delay constraint for a multi-user wireless system. We address this problem within the framework of constrained Markov decision processes (CMDPs) wherein one seeks to minimize one cost (average power) subject to a hard constraint on another (average delay). We do not assume the arrival and channel statistics to be known. To handle state space explosion and informational constraints, we split the problem into individual CMDPs for the users, coupled through their Lagrange multipliers; and a user selection problem at the base station. To address the issue of unknown channel and arrival statistics, we propose a reinforcement learning algorithm. The users use this learning algorithm to determine the rate at which they wish to transmit in a slot and communicate this to the base station. The base station then schedules the user with the highest rate in a slot. We analyze convergence, stability and optimality properties of the algorithm. We also demonstrate the efficacy of the algorithm through simulations within IEEE 802.16 system.
A Review of Microfiber and Nanofiber Based Optical Sensors

Rapid advances in optical microfiber and nanofibers (MNF) based sensors have been driven by powerful industries such as automotive, biomedical and defense, with the increasing demand for highly-sensitive, selective, nonintrusive, fast-response, compact and robust sensors that can perform in-situ measurements at remote and harsh environments. A diverse range of MNF based sensors have been developed for measuring refractive index, bio-chemical, temperature, current, displacement, bend, surface, acceleration, force, rotation, acoustic, electric field and magnetic field. Given the growing interest for this exciting area of scientific research, new designs are emerging continuously at a fast pace. This paper attempts to provide a comprehensive review of all MNF based sensors reported to-date. Sensors are divided according to their morphology and measurand.
Anti-tumor necrosis factor therapy increases serum adiponectin levels with the improvement of endothelial dysfunction in patients with rheumatoid arthritis

Lower adiponectin levels in circulation are shown to be associated with endothelial dysfunction, which is a crucial feature in the evolution of atherosclerosis. The aim of our study is to evaluate the effect of anti-tumor necrosis factor (TNF) therapy on adiponectin levels with endothelial function and arterial stiffness. Fifteen Japanese patients with rheumatoid arthritis (RA) received infusions with infliximab (3 mg/kg) at weeks 0, 2, and 6. Serum concentrations of adiponectin, endothelial function, and pulse wave velocity (PWV) were measured before each infusion. Endothelium-dependent vasodilatation and endothelium-independent vasodilatation were evaluated as forearm blood flow response to reactive and nitroglycerin-induced hyperemia using strain-gauge plethysmography. Endothelium-dependent vasodilatation was significantly improved at 2 weeks and 6 weeks by treatment with infliximab. PWV remained unchanged. Anti-TNF therapy significantly increased serum adiponectin levels at 2 weeks and 6 weeks. The adiponectin levels were positively correlated with the endothelium-dependent vasodilatation, and negatively with the disease activity score of 28 joints. Our study shows a short-term efficacy of infliximab on adiponectin levels and endothelial dysfunction of patients with RA, and provides additional evidence to support the regulatory role of TNF-α on the expression of adiponectin in vivo.
Head, eye and arm coordination in table tennis

The aim of this study was to determine the role of head, eye and arm movements during the execution of a table tennis forehand stroke. Three-dimensional kinematic analysis of line-of-gaze, arm and ball was used to describe visual and motor behaviour. Skilled and less skilled participants returned the ball to cued right or left target areas under three levels of temporal constraint: pre-, early- and late-cue conditions. In the pre- and early-cue conditions, both high and low skill participants tracked the ball early in flight and kept gaze stable on a location in advance of the ball before ball-bat contact. Skilled participants demonstrated an earlier onset of ball tracking and recorded higher performance accuracy than less skilled counterparts. The manipulation of cue condition showed the limits of adaptation to maintain accuracy on the target. Participants were able to accommodate the constraints imposed by the early-cue condition by using a shorter quiet eye duration, earlier quiet eye offset and reduced arm velocity at contact. In the late-cue condition, modifications to gaze, head and arm movements were not sufficient to preserve accuracy. The findings highlight the functional coupling between perception and action during time-constrained, goal-directed actions.
