Enabling PID and SSSC for load frequency control using Particle Swarm Optimization

Rapid human population has led to increasing number of load demand. This load demand increased could potentially lead to instability of power system such as frequency stability. It is well known that governor has a significant role in controlling frequency on the generator. Generally, the governor usually used simple integral controller as the controller. However, with increasing number of load and rapid load changing, integral control only is not enough to handle the problems. Hence, deployment additional devices such as flexible alternating current transmission systems (FACTS) devices and changing the governor controller to PID controller is crucial. This paper proposed an enhancement of load frequency control using PID controller and Static Synchronous Series Compensator (SSSC). A Particle Swarm Optimization (PSO) is used as an optimization method to find the best parameter. Two area power system are used as a test system to analyze the performance of system with proposed method (PID and SSSC based on PSO). To examine the performance of the system with or without proposed method. From the simulation, it is found by using PID and SSSC based on PSO the frequency performance of the system is enhanced.
Cardiac interbeat interval dynamics from childhood to senescence : comparison of conventional and new measures based on fractals and chaos theory.

BACKGROUND New methods of R-R interval variability based on fractal scaling and nonlinear dynamics ("chaos theory") may give new insights into heart rate dynamics. The aims of this study were to (1) systematically characterize and quantify the effects of aging from early childhood to advanced age on 24-hour heart rate dynamics in healthy subjects; (2) compare age-related changes in conventional time- and frequency-domain measures with changes in newly derived measures based on fractal scaling and complexity (chaos) theory; and (3) further test the hypothesis that there is loss of complexity and altered fractal scaling of heart rate dynamics with advanced age. METHODS AND RESULTS The relationship between age and cardiac interbeat (R-R) interval dynamics from childhood to senescence was studied in 114 healthy subjects (age range, 1 to 82 years) by measurement of the slope, beta, of the power-law regression line (log power-log frequency) of R-R interval variability (10(-4) to 10(-2) Hz), approximate entropy (ApEn), short-term (alpha(1)) and intermediate-term (alpha(2)) fractal scaling exponents obtained by detrended fluctuation analysis, and traditional time- and frequency-domain measures from 24-hour ECG recordings. Compared with young adults (<40 years old, n=29), children (<15 years old, n=27) showed similar complexity (ApEn) and fractal correlation properties (alpha(1), alpha(2), beta) of R-R interval dynamics despite lower spectral and time-domain measures. Progressive loss of complexity (decreased ApEn, r=-0.69, P<0.001) and alterations of long-term fractal-like heart rate behavior (increased alpha(2), r=0.63, decreased beta, r=-0.60, P<0.001 for both) were observed thereafter from middle age (40 to 60 years, n=29) to old age (>60 years, n=29). CONCLUSIONS Cardiac interbeat interval dynamics change markedly from childhood to old age in healthy subjects. Children show complexity and fractal correlation properties of R-R interval time series comparable to those of young adults, despite lower overall heart rate variability. Healthy aging is associated with R-R interval dynamics showing higher regularity and altered fractal scaling consistent with a loss of complex variability.
Image sequence enhancement using multiple motions analysis

A method for detecting and tracking multiple moving objects, using both a large spatial region and a large temporal region, without assuming temporal motion constancy is described. When the large spatial region of analysis has multiple moving objects, the motion parameters and the locations of the objects are computed for one object after another. A method for segmenting the image plane into differently moving objects and computing their motions using two frames is presented. The tracking of detected objects using temporal integration and the algorithms for enhancement of tracked objects by filling-in occluded regions and by improving the spatial resolution of the imaged objects are described. <<ETX>>
The Use of the MPI Communication Library in the NAS Parallel Benchmarks

The statistical analysis of traces taken from the NAS Parallel Benchmarks can tell one much about the type of network tra c that can be expected from scienti c applications run on distributed memory parallel computers. For instance, such applications utilize a relatively few number of communication library functions, the length of their messages is widely varying, they use many more short messages than long ones, and within a single application the messages tend to follow relatively simple patterns. Hardware and software designers can use information such as this to optimize their systems for the highest possible performance. This paper presents speci c data on how these generally known characteristics about distributed memory applications are exhibited in the NAS Parallel Benchmarks.
Hepatocyte cell lines: their use, scope and limitations in drug metabolism studies

Gaining knowledge on the metabolism of a drug, the enzymes involved and its inhibition or induction potential is a necessary step in pharmaceutical development of new compounds. Primary human hepatocytes are considered a cellular model of reference, as they express the majority of drug-metabolising enzymes, respond to enzyme inducers and are capable of generating invitro a metabolic profile similar to what is found in vivo. However, hepatocytes show phenotypic instability and have a restricted accessibility. Different alternatives have been explored in the past recent years to overcome the limitations of primary hepatocytes. These include immortalisation of adult or fetal human hepatic cells by means of transforming tumour virus genes, oncogenes, conditionally immortalised hepatocytes, and cell fusion. New strategies are currently being used to upregulate the expression of drug-metabolising enzymes in cell lines or to derive hepatocytes from progenitor cells. This paper reviews the features of liver-derived cell lines, their suitability for drug metabolism studies as well as the state-of-the-art of the strategies pursued in order to generate metabolically competent hepatic cell lines.
Impact of the first 5 years of a national abdominal aortic aneurysm screening programme

The Abdominal Aortic Aneurysm (AAA) Screening Programme was introduced by the National Health Service (NHS) in England to reduce the rate of death from ruptured AAA in men. The programme commenced in 2009 and was implemented completely across the country in April 2013. The aim was to review the first 5 years of the programme, looking specifically at compliance and early outcome.
Not only the Sugar, Early infarct sign, hyperDense middle cerebral artery, Age, Neurologic deficit score but also atrial fibrillation is predictive for symptomatic intracranial hemorrhage after intravenous recombinant tissue plasminogen activator

ABSTRACT Background: Symptomatic intracranial hemorrhage (sICH) is the most unwanted adverse event in patients with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator (i.v. rt-PA). Many tool scores are available to predict the probability of sICH. Among those scores, the Sugar, Early infarct sign, hyperDense middle cerebral artery, Age, Neurologic deficit (SEDAN) gives the highest area under the curve-receiver operating characteristic value. Objective: We aimed to examine any factors other than the SEDAN score to predict the probability of sICH. Methods: Patients with acute ischemic stroke treated with i.v. rt-PA within 4.5 h time window from January 2010 to July 2012 were evaluated. Compiling demographic data, risk factors, and comorbidity (hypertension, diabetes mellitus, dyslipidemia, atrial fibrillation (AF), ischemic heart disease, valvular heart disease, previous stroke, gout, smoking cigarette, drinking alcoholic beverage, family history of stroke, and family history of ischemic heart disease), computed tomography scan of patients prior to treatment with rt-PA, and assessing the National Institutes of Health Stroke Scale (NIHSS) score for the purpose of calculating SEDAN score were analyzed. Results: Of 314 patients treated with i.v. rt-PA, there were 46 ICH cases (14.6%) with 14 sICH (4.4%) and 32 asymptomatic intracranial hemorrhage cases (10.2%). The rate of sICH occurrence was increased in accordance with the increase in the SEDAN score and AF. Age over 75 years, early infarction, hyperdense cerebral artery, baseline blood sugar more than 12 mmol/l, NIHSS as 10 or more, and AF were the risk factors to develop sICH after treated with rt-PA at 1.535, 2.501, 1.093, 1.276, 1.253, and 2.492 times, respectively. Conclusions: Rather than the SEDAN score, AF should be a predictor of sICH in patients with acute ischemic stroke after i.v. rt-PA treatment in Thai population.
Epidemiology, management, and outcome of severe acute renal failure of critical illness in Australia

ObjectiveTo study the epidemiology, style of management, and outcome of intensive care patients with acute renal failure requiring replacement therapy in Australia. DesignProspective epidemiologic study. SettingAustralian adult intensive care units providing acute renal replacement therapy. PatientsAdult intensive care patients with acute renal failure treated with renal replacement therapy. InterventionsDemographic and clinical data collection for 3 months. Measurements and Main Results A standardized data collection form for each case of severe acute renal failure was used to collect demographic, biochemical, clinical, and outcome data. Severe acute renal failure affected 299 patients (approximately eight cases per 100,000 adults per year). Among these patients, 99 (33.1%) had impaired baseline renal function, 238 (79.6%) needed mechanical ventilation, and 232 (77.6%) needed continuous vasoactive drug administration. Critical care physicians controlled patient care and renal replacement therapy in 289 cases (96.7%). Critical care nurses performed such therapy alone in 288 (96.3%) cases. Continuous renal replacement therapy was used in 292 (97.7%) patients. There was no nephrological input in 173 (57.8%) cases. Predicted mortality rates were 52.1% by Simplified Acute Physiology Score II, 49.5% by Acute Physiology and Chronic Health Evaluation II score, and 51.9% by an acute renal failure-specific score. Actual mortality rate was 46.8%. Only 25 (15.7%) patients were dialysis-dependent at hospital discharge. Of these patients, 20 (80%) had premorbid chronic impairment of renal function. ConclusionIn Australia, critical care physicians and nurses manage severe acute renal failure with limited consultative nephrological input. Renal replacement therapy is continuous and outcomes are satisfactory. Our findings support the view that this approach to management of severe acute renal failure is safe.
Energy Efficient Privacy Preserved Data Gathering in Wireless Sensor Networks Having Multiple Sinks

Wireless sensor networks (WSNs) generally have a many-to-one structure so that event information flows from sensors to a unique sink. In recent WSN applications, many-to- many structures are evolved due to need for conveying collected event information to multiple sinks at the same time. This study proposes an anonymity method bases on k-anonymity for preventing record disclosure of collected event information in WSNs. Proposed method takes the anonymity requirements of multiple sinks into consideration by providing different levels of privacy for each destination sink. Attributes, which may identify of an event owner, are generalized or encrypted in order to meet the different anonymity requirements of sinks. Privacy guaranteed event information can be multicasted to all sinks instead of sending to each sink one by one. Since minimization of energy consumption is an important design criteria for WSNs, our method enables us to multicast the same event information to multiple sinks and reduce energy consumption.
AUGMENTED REALITY ON ARCHITECTURAL AND BUILDING ENGINEERING LEARNING PROCESSES. TWO STUDY CASES

In this paper we present the first conclusions of an educational research project which seeks to evaluate graphic and spatial capabilities improvement of undergraduate and master's degree in architecture, construction, urbanism and design students, throughout their academic training period, and by the use of Augmented Reality (AR) technology. The whole project consists of twelve case studies to be carried out in several university centers. At this moment, after the two finished case studies, it has been demonstrated that by combining the use of an attractive technology, to create dynamic photomontage for visual evaluation of virtual models in a real environment, and by the user-machine interaction that involves the AR, students feel more motivated, development and evolution of graphic competences and space skills are increased in shorter learning periods, and their academic performance is highly improved. We have used for this experience mobile phones, laptops, as well as low cost AR applications.
Probabilistic strategies to coordinate multiple robotic pursuers in pursuit-evasion games

This paper examines the problem of coordinating multiple robotic pursuers in locating and tracking a non-adversarial mobile evader in a dynamic environment. We have proposed a probabilistic and distributed algorithm in this paper. Our method considers the uncertain state information of the pursuers and the evader using the probabilistic formulation of the pursuit-evasion problem, in order to minimize the expected time of capture rather than guaranteeing capture. Unlike many other approaches to this problem, our method provides a distributed technique to enhance the search efficiency of multiple pursuers as a result of avoiding overlapping search. Finally, we present simulated results to demonstrate the performance of our algorithm in a complex dynamic environment. The results show that our algorithm successfully reduces the expected capture time of the evader with a limited number of pursuers.
Spatialized audioconferencing: what are the benefits?

Audioconference participants often have difficulty identifying the voices of other conferees, especially in ad hoc groups of unfamiliar members. Simultaneous presentation of multiple voices through a single, monaural channel can be discordant and difficult to comprehend. To address these shortcomings, we have developed the Vocal Village, a communications tool that allows for real-time spatialized audioconferencing across the Internet. The Vocal Village system uses binaural audio signals to present the voices of individual conference participants from different apparent positions in space by adding location cues to audio information.This paper describes our experimental research to determine whether the real-time, "within the head," spatialization cues implemented by Vocal Village are sufficient to provide performance benefits compared to traditional, monaural audio-conferencing methods. Performance benefits included memory, speaker identification, and participant preference. We also investigated whether providing users with the ability to control the location of conference participants within a virtual auditory space further enhanced any such benefits.The "within the head" spatialization used in this experiment did not lead to a statistically significant increase in the ability to remember who said what in an audioconference. However, there was a borderline significant increase in remembering who said what when participants were given the opportunity to move the voices of two similar sounding conferees into different apparent locations. Participants also significantly preferred spatialized audio formats over the mono audio format. Spatialization had a significant effect on improving participants' perceived confidence in their memory of conferee viewpoints. Additionally, spatialization significantly reduced both the perceived difficulty of identifying speakers during conferences, as well as the amount of attention perceived to be dedicated to performing such voice identification. Providing subjects with the ability to control the apparent location of conference participants resulted in the greatest benefit to both of these measures.
In silico bone mechanobiology: modeling a multifaceted biological system

Mechanobiology, the study of the influence of mechanical loads on biological processes through signaling to cells, is fundamental to the inherent ability of bone tissue to adapt its structure in response to mechanical stimulation. The immense contribution of computational modeling to the nascent field of bone mechanobiology is indisputable, having aided in the interpretation of experimental findings and identified new avenues of inquiry. Indeed, advances in computational modeling have spurred the development of this field, shedding new light on problems ranging from the mechanical response to loading by individual cells to tissue differentiation during events such as fracture healing. To date, in silico bone mechanobiology has generally taken a reductive approach in attempting to answer discrete biological research questions, with research in the field broadly separated into two streams: (1) mechanoregulation algorithms for predicting mechanobiological changes to bone tissue and (2) models investigating cell mechanobiology. Future models will likely take advantage of advances in computational power and techniques, allowing multiscale and multiphysics modeling to tie the many separate but related biological responses to loading together as part of a larger systems biology approach to shed further light on bone mechanobiology. Finally, although the ever‐increasing complexity of computational mechanobiology models will inevitably move the field toward patient‐specific models in the clinic, the determination of the context in which they can be used safely for clinical purpose will still require an extensive combination of computational and experimental techniques applied to in vitro and in vivo applications.

Ventricular Diastolic Function in Normal Fetuses and Fetuses with Hb Bart’s Disease Assessed by Color M-Mode Propagation Velocity using Cardio-STIC-M (Spatio-Temporal Image Correlation M-Mode)

Abstract Purpose: To determine whether ventricular diastolic dysfunction contributes to the pathogenesis of fetal cardiac failure due to fetal anemia using fetal Hb Bart’s disease as a live model and cardio-STIC-M as a diagnostic tool. Materials and Methods: Color cardio-STIC volume datasets were acquired from fetuses at risk for Hb Bart’s disease during 18 – 22 weeks of gestation and normal pregnancies and pregnancies with hydrops fetalis caused by Hb Bart’s disease at 28 – 32 weeks. The volumes were analyzed off-line for velocity propagation (Vp) of the right and left ventricles to assess ventricular diastolic function using color cardio-STIC-M. Results: The Vp for the right and left ventricles was studied in fetuses at 18 – 22 weeks, including 64 normal fetuses (group 1) and 22 fetuses with Hb Bart’s disease (group 2), and in fetuses at 28 – 32 weeks, including 22 normal fetuses (group 3) and 16 fetuses with Hb Bart’s hydrops fetalis (group 4). The Vp of the fetuses in group 1 and group 2 was not significantly different. However, the Vp for the right and left ventricles in group 4 was significantly lower than in group 3 (19.02 vs. 9.78, p < 0.001; and 20.24 vs. 13.40, p < 0.001, respectively). The inter-observer variability had fair agreement with the intra-class correlation coefficient of 0.531 (95 % CI 0.393 – 0.646, p < 0.001). Conclusion: Hydrops fetalis secondary to fetal anemia is initially caused by hypervolemia rather than ventricular diastolic dysfunction while ventricular diastolic compromise is a late occurring consequence of persistent hypervolemia, different from the mechanism of hydropic changes caused by cardiac causes.

High-volume calcium hydroxylapatite filler to the lower one-third of the face.

infections, it can also cause highly invasive and potentially lethal infections, including necrotizing pneumonia, septic cavernous sinus thrombosis, and pyogenic brain abscess. The fulminant nature of these unusual cases has led many investigators to speculate that CA-MRSA may be more virulent than HA-MRSA. In fact, CA-MRSA strains have been shown to be more virulent than HA-MRSA in neutrophil survival and murine infection studies; however, the factors that may make CA-MRSA more virulent or transmissible have not yet been clearly defined. Herein, we present a case of surgical site infection after face-lift surgery caused by the epidemic strain of CAMRSA USA300. At least 1 of the cases of MRSA face-lift wound infection described by Zoumalan and Rosenberg was also likely caused by a CA-MRSA strain based on the antibiotic susceptibility pattern of the isolate, but molecular analysis was not performed. To our knowledge, this is the first report of death attributable to an infection complicating face-lift surgery and the first fatal case of septic dural sinus thrombosis caused by CAMRSA. In the preantibiotic era, uncontrolled infections of the face were a common cause of septic dural sinus thromboses, and mortality rates of these now-rare conditions remain high in the modern era (30% for septic cavernous sinus thrombosis, 78% for septic sagittal sinus thrombosis). The emergence of MRSA as a CA pathogen will likely be an ongoing challenge in the care of ambulatory surgery patients. All MRSA wound infections should be treated aggressively with surgical drainage and appropriate antibiotic therapy. A recent study reporting a higher than 90% cure rate of uncomplicated CA-MRSA skin abscesses with incision and drainage combined with either a placebo or an antibiotic predicted to be ineffective (cephalexin) is yet another clear demonstration of the primacy of surgical drainage in the treatment of these infections. Less clear and in need of study are the optimal methods to identify, treat, and prevent disease in ambulatory patients at risk for MRSA surgical site infections. In conclusion, emergence of MRSA within the community represents a clear and present danger to individuals traditionally considered to be at low risk for MRSA infection, including those undergoing ambulatory surgical procedures.
