THD comparison for power quality (MATLAB simulation & hardware)

Power quality shows the fitness of electrical power system. In recent years, efforts are made to upgrade power quality. Multi pulse converters are used to achieve good quality of electrical power. Phase shift transformer is used to obtain 12 and 24 pulses as outputs. The quality of power mainly depends on some parameters like, variation in voltage magnitude, transients in voltage/current, harmonic content in waveforms etc. So in this paper, improvement in power quality is shown by comparing the THD (total harmonic distortion) of 6, 12 & 24 pulses. In this paper, the results of MATLAB are verified with the hardware results.
Identification of Closely Related Indigenous Languages: An Orthographic Approach

The main focus of this study is to identify the closely related languages amongst the indigenous languages of Sarawak and major languages such as Bahasa Melayu and English. The indigenous languages involved in this study include Iban (standard), Bidayuh (Bau-Jagoi), Kelabit (Bario), Melanau (Matu-Daro), Sa’ban (Long Banga) and Penan (East Baram). The relationship between the languages is established via the proportion of cognates in the Swadesh list of the language pairs. The orthographic approach, which primarily examines the spelling of the vocabulary words, is used. The outcome of this study reveals that some indigenous languages are more closely related to to Bahasa Melayu than others. The findings from this research serve as an initial solution to answer the greater challenges in computational linguistics, such as the use of closely related languages as Pivot solutions in problems related to the under-resourced languages.
A randomized controlled trial of inspiratory muscle training in stable chronic heart failure.

AIMS
To assess whether a domiciliary programme of specific inspiratory muscle training in stable chronic heart failure results in improvements in exercise tolerance or quality of life.


METHODS AND RESULTS
We conducted a randomized controlled trial of 8 weeks of inspiratory muscle training in 18 patients with stable chronic heart failure, using the Threshold trainer. Patients were randomized either to a training group inspiring for 30 min daily at 30% of maximum inspiratory mouth pressure, or to a control group of 'sham' training at 15% of maximum inspiratory mouth pressure. Sixteen of the 18 patients completed the study. Maximum inspiratory mouth pressure improved significantly in the training group compared with controls, by a mean (SD) of 25.4 (11.2) cmH2O (P=0.04). There were, however, no significant improvements in treadmill exercise time, corridor walk test time or quality of life scores in the trained group compared with controls.


CONCLUSION
Despite achieving a significant increase in inspiratory muscle strength, this trial of simple domiciliary inspiratory muscle training using threshold loading at 30% of maximum inspiratory mouth pressure did not result in significant improvements in exercise tolerance or quality of life in patients with chronic heart failure.

Heavy ion single-event effect (SEE) measurements on Xilinx Zynq-7000 are reported. Heavy ion susceptibility to Single-Event latchup (SEL), single event upsets (SEUs) of BRAM, configuration bits of FPGA and on chip memory (OCM) of the processor were investigated.
Ecuador's Rural Nonfarm Sector as a Route Out of Poverty

This paper analyzes a recent household survey for Ecuador to assess the role of the non-agricultural rural sector in reducing poverty. The rural non-agricultural sector in Ecuador accounts for roughly 40% of rural incomes. Nearly 40% of men and 50% of economically active women are employed in this sector. The sector represents an important route out of poverty--poverty declines as the share of total income from non-agricultural sources rises. Non-agricultural employment and earnings are positively associated with higher education levels and better access to infrastructural services. While women are more likely to be employed in this sector than are men, their earnings for given education levels and other household characteristics are significantly lower. All other things equal, the greatest income gains among the poor could be expected from an expansion of employment opportunities in commerce related activities, transport, and services such as administration and the hotel/restaurant trade.
Paper windows: interaction techniques for digital paper

In this paper, we present Paper Windows, a prototype windowing environment that simulates the use of digital paper displays. By projecting windows on physical paper, Paper Windows allows the capturing of physical affordances of paper in a digital world. The system uses paper as an input device by tracking its motion and shape with a Vicon Motion Capturing System. We discuss the design of a number of interaction techniques for manipulating information on paper displays.
REWIEW OF LITERATURE 3.1. URINARY TRACT INFECTION

3.1. URINARY TRACT INFECTION Urinary tract infection is one of the important causes of morbidity and mortality in Indian population, affecting all age groups across the life span. Anatomically, urinary tract is divided into an upper portion composed of kidneys, renal pelvis, and ureters and a lower portion made up of urinary bladder and urethra. UTI is an inflammatory response of the urothelium to bacterial invasion that is usually associated with bacteriuria and pyuria. UTI may involve only the lower urinary tract or both the upper and lower tract [19].

Anxiety and Depression in Patients with Traumatic Spinal Cord Injury: A Nationwide Population-Based Cohort Study

BACKGROUND
Traumatic spinal cord injury (tSCI) may involve new-onset anxiety and depression post-discharge. However, long-term population-based studies have lacked access to follow-up conditions in terms of new-onset anxiety and depression. The objective of this study was to estimate the long-term risk of new-onset anxiety and depression post-discharge.


METHODS
The Longitudinal Health Insurance Database 2000 (LHID2000) from Taiwan's National Health Insurance Research Database was used in this study. Individuals with tSCI were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic codes of 806 and 952 from 1999-2008. The comparison cohort (other health conditions group) was randomly selected from the LHID2000 and was 1:1 matched by age, sex, index year, and comorbidities to reduce the selection bias. All study participants were retrospectively followed for a maximum of 3 years until the end of follow-up, death, or new-onset anxiety (ICD-9-CM: 309.2-309.4) or depression (ICD-9-CM: 296.2, 296.5, 296.82, 300.4, 309.0-309.1, and 311). Persons who were issued a catastrophic illness card for tSCI were categorized as having a severe level of SCI (Injury Severity Score [ISS] ≥16). Poisson regression was used to estimate the incidence rate ratios of anxiety or depression between patients with tSCI and other health conditions. The relative risk of anxiety or depression was estimated using a Cox regression analysis, which was adjusted for potential confounding factors.


RESULTS
Univariate analyses showed that the tSCI patients (n = 3556) had a 1.33 times greater incidence of new-onset anxiety or depression (95% confidence interval [CI]: 1.12-1.57) compared to the other health conditions group (n = 3556). After adjusting for potential risk factors, the tSCI patients had a significant 1.29-fold increased risk of anxiety or depression compared to the group with other health conditions (95% CI: 1.09-1.53). Individuals with tSCI, including patients who were under the age of 35, patients who were males, patients who had a low income, and patients without a Charlson Comorbidity Index score, all had a higher long-term risk of anxiety or depression than the other health conditions group (IRRs: 1.84, 1.63, 1.29, and 1.39, respectively). For all tSCI patients, those with an Injury Severity Score (ISS) ≥16 had an almost 2-fold higher risk of anxiety or depression (adjusted Hazard Ratio: 1.85; 95% CI: 1.17-2.92) compared to those with ISS <16.


CONCLUSIONS
Our findings indicated that tSCI patients have a high risk of anxiety or depression post-discharge, especially among the younger tSCI patients (age <50 years), compared with the other health conditions group. This information could help physicians understand the long-term risk of new-onset anxiety or depression in tSCI patients post-discharge.
Impact of initiating carvedilol before angiotensin-converting enzyme inhibitor therapy on cardiac function in newly diagnosed heart failure.

OBJECTIVES
The purpose of this research was to evaluate the therapeutic value of initiating a beta-blocker before an angiotensin-converting enzyme inhibitor (ACEI) in the treatment of heart failure.


BACKGROUND
Although ACEI and carvedilol produce benefits in heart failure, whether the order of initiation of therapy determines the impact on left ventricular (LV) function and New York Heart Association functional class (NYHA FC) has not been determined.


METHODS
A single-center, prospective, randomized, open-label study was performed. We evaluated whether initiation of therapy with carvedilol either before (n = 38) or after (n = 40) perindopril therapy in newly diagnosed patients in NYHA FC II to III heart failure with idiopathic dilated cardiomyopathy, with the addition of the alternative agent after six months, determined subsequent changes in NYHA FC and LV function (echocardiography and radionuclide ventriculography). Study drugs were titrated to maximum tolerable doses.


RESULTS
There were no differences in baseline characteristics between the study groups. After 12 months 11 patients died (6 in the group where the ACEI was initiated). At 12 months the group receiving carvedilol as initial therapy achieved a higher tolerable dose of carvedilol (43 +/- 17 mg vs. 33 +/- 18 mg, p = 0.03); a lower dose of furosemide (p < 0.05); and better improvements in symptoms (NYHA FC, p < 0.002), LV ejection fraction (radionuclide: 15 +/- 16% vs. 6 +/- 13%, p < 0.05; echocardiographic, p < 0.01), and plasma N-terminal pro-brain natriuretic peptide concentrations (p < 0.02).


CONCLUSIONS
As opposed to the conventional sequence of drug use in the treatment of heart failure, initiation of therapy with carvedilol before an ACEI results in higher tolerable doses of carvedilol and better improvements in FC and LV function.
Super-twisting sliding mode direct torque contol of induction machine drives

This paper presents a new super-twisting sliding modes direct torque and flux controller (STSM-DTC) for induction motor (IM) drives. The STSM is a second-order (type two) variable-structure control which operates without high-frequency chattering. The proposed STSM scheme is a torque and stator flux magnitude controller implemented in the stator flux reference frame, and it does not employ current controllers as in conventional vector control. This controller contains a design parameter that allows the designer to balance its operation between a linear PI-like behavior and a constant-gain sliding-mode-like behavior. The experimental tests show that the STSM-DTC controller displays very robust behavior, similar to a conventional sliding controller, and it works without notable steady-state chattering, like the PI controller. The paper presents theoretical aspects for the new STSM-DTC control, design and implementation details, and relevant experimental results for a sensorless IM drive. The scheme is compared to a second-order sliding mode controller and a linear PI controller. A robustness assessment against the PI controller is also included.
Feature hashing for large scale multitask learning

Empirical evidence suggests that hashing is an effective strategy for dimensionality reduction and practical nonparametric estimation. In this paper we provide exponential tail bounds for feature hashing and show that the interaction between random subspaces is negligible with high probability. We demonstrate the feasibility of this approach with experimental results for a new use case --- multitask learning with hundreds of thousands of tasks.
The Authority of "Fair" in Machine Learning

In this paper, we argue for the adoption of a normative definition of fairness within the machine learning community. After characterizing this definition, we review the current literature of Fair ML in light of its implications. We end by suggesting ways to incorporate a broader community and generate further debate around how to decide what is fair in ML.
The Rate and Risk Factors for Anemia among Pregnant Mothers in Jerteh Terengganu, Malaysia

Background: Antenatal mothers with anemia are high risk to varieties of health implications as well as to their off springs. Many studies show a high mortality and morbidity related to anemia in pregnancy. Methods: This cross-sectional study was designed to determine factors associated with anemia amongst forty seven antenatal mothers attending Antenatal Clinic at Klinik Kesihatan Kuala Besut, Terengganu in November 2009. Systematic random sampling was applied and information gathered based on patients’ medical records and through face-to-face interviewed by using a structured questionnaire. Results: The mean age of respondents was 28.3 year-old. More than half of mothers were multigravidas. Of 47 respondents, 57.4% (95% CI: 43.0, 72.0) was anemic. The proportion of anemia was high for grand multigravidas mother (66.7%), those at third trimester of pregnancy (70.4%), did antenatal booking at first trimester (65.4%), poor haematinic compliance (76.5%), not taking any medication (60.5%), those with no co-morbid illnesses (60.0%), mothers with high education level (71.4%) and those with satisfactory monthly income (61.5%). The proportion of anemia was 58.3% and 57.1% for mothers with last child birth spacing of two years or less and more than two years accordingly. There was a significant association of haematinic compliance with the anemia (OR: 4.571; 95% CI: 1.068, 19.573). Conclusions: Antenatal mothers in this area have a substantial proportion of anemia despite of freely and routinely prescription of haematinic at primary health care centers. Poor haematinic compliance was a significant risk factor. Health education programs regarding haematinic compliance and adequate intake of iron rich diet during pregnancy need to be strengthened to curb this problem. *Corresponding author: NH Nik Rosmawati, Environmental Health Unit, Department of Community Medicine, School of Medical Science, Health Campus, Universiti Sains Malaysia, 16150 Kubang Kerian, Kelantan, Malaysia, E-mail: rosmawati@kk.usm.my Received May 03, 2012; Accepted May 24, 2012; Published May 26, 2012 Citation: Nik Rosmawati NH, Mohd Nazri S, Mohd Ismail I (2012) The Rate and Risk Factors for Anemia among Pregnant Mothers in Jerteh Terengganu, Malaysia.

Intensive referral to 12-Step self-help groups and 6-month substance use disorder outcomes.

AIMS
This study implemented and evaluated procedures to help clinicians make effective referrals to 12-Step self-help groups.


DESIGN
Randomized controlled trial. Setting Out-patient substance use disorder treatment. Participants Individuals with substance use disorders (SUDs) entering a new treatment episode (n = 345) who were assigned randomly to a standard referral- or an intensive referral-to-self-help condition.


MEASUREMENTS
Self-reports of 12-Step group attendance and involvement and substance use at baseline and a 6-month follow-up.


INTERVENTION
The intensive referral intervention focused on encouraging patients to attend 12-Step meetings by connecting them to 12-Step volunteers.


FINDINGS
Among patients with relatively less previous 12-Step meeting attendance, intensive referral was associated with more meeting attendance during follow-up than was standard referral. Among all patients, compared with those who received standard referral, those who received intensive referral were more likely to be involved with 12-Step groups during the 6-month follow-up (i.e. had provided service, had a spiritual awakening and currently had a sponsor). Intensive referral patients also had better alcohol and drug use outcomes at 6 months. Twelve-Step involvement mediated part of the association between referral condition and alcohol outcomes.


CONCLUSIONS
The brief intensive referral intervention was associated with improved 12-Step group involvement and substance use outcomes even among patients with considerable previous 12-Step group exposure and formal treatment. Future 12-Step intensive referral procedures should focus on encouraging 12-Step group involvement in addition to attendance to benefit patients most effectively.
Effectiveness of regional DTI measures in distinguishing Alzheimer's
disease, MCI, and normal aging☆

The Alzheimer's Disease Neuroimaging Initiative (ADNI) recently added diffusion tensor imaging (DTI), among several other new imaging modalities, in an effort to identify sensitive biomarkers of Alzheimer's disease (AD). While anatomical MRI is the main structural neuroimaging method used in most AD studies and clinical trials, DTI is sensitive to microscopic white matter (WM) changes not detectable with standard MRI, offering additional markers of neurodegeneration. Prior DTI studies of AD report lower fractional anisotropy (FA), and increased mean, axial, and radial diffusivity (MD, AxD, RD) throughout WM. Here we assessed which DTI measures may best identify differences among AD, mild cognitive impairment (MCI), and cognitively healthy elderly control (NC) groups, in region of interest (ROI) and voxel-based analyses of 155 ADNI participants (mean age: 73.5 ± 7.4; 90 M/65 F; 44 NC, 88 MCI, 23 AD). Both VBA and ROI analyses revealed widespread group differences in FA and all diffusivity measures. DTI maps were strongly correlated with widely-used clinical ratings (MMSE, CDR-sob, and ADAS-cog). When effect sizes were ranked, FA analyses were least sensitive for picking up group differences. Diffusivity measures could detect more subtle MCI differences, where FA could not. ROIs showing strongest group differentiation (lowest p-values) included tracts that pass through the temporal lobe, and posterior brain regions. The left hippocampal component of the cingulum showed consistently high effect sizes for distinguishing groups, across all diffusivity and anisotropy measures, and in correlations with cognitive scores.
Imatinib mesylate as a preoperative therapy in dermatofibrosarcoma: results of a multicenter phase II study on 25 patients.

AIMS
The treatment of dermatofibrosarcoma protuberans (DFSP) involves wide local excision with frequent need for reconstructive surgery. A t(17;22) translocation resulting in COL1A1-PDGFB fusion is present in >95% of cases. Certain patient observations and a report on nine patients suggest that imatinib mesylate, targeting platelet-derived growth factor receptor beta, has clinical potential in DFSP. The primary aim of this phase II multicenter study was to define the percentage of clinical responders (Response Evaluation Criteria in Solid Tumors) to a 2-month preoperative daily administration of 600 mg of imatinib mesylate before wide local excision. The secondary aims were to determine tolerance, objective response from imaging results (ultrasound and magnetic resonance imaging), and pathologic responses observed in sequential tissue specimens.


PATIENTS AND METHODS
A two-stage flexible design was used with interim analysis after the recruitment of six patients. Twenty-five adults suffering from primary or recurrent DFSP were included from July 2004 to May 2006.


RESULTS
The COL1A1-PDGFB fusion gene was detected in 21 out of 25 patients following fluorescence in situ hybridization analysis (two cases were noninformative). A clinical response was achieved in nine (36%) patients (95% confidence interval, 18.9-57.5). The median relative tumoral decrease was 20.0% (range, -12.5 to 100). Apart from expected grade 1 or 2 side effects, we observed one grade 3 neutropenia, one grade 3 maculopapular rash, and one grade 4 transient transaminitis.


CONCLUSION
Our results support the use of imatinib in a neoadjuvant setting in nonresectable DFSP, or when surgery is difficult or mutilating. These results will be useful for setting hypotheses in the evaluation of new drugs to treat primary or secondary resistance to imatinib.
Computing in the curriculum: Challenges and strategies from a teacher’s perspective

Computing is being introduced into the curriculum in many countries. Teachers’ perspectives enable us to discover what challenges this presents, and also the strategies teachers claim to be using successfully in teaching the subject across primary and secondary education. The study described in this paper was carried out in the UK in 2014 where teachers were preparing for the mandatory inclusion of Computing into the curriculum. A survey was conducted of over 300 teachers who were currently teaching Computing to elicit their perspectives on challenges and strategies. From the analysis of the data, extrinsic and intrinsic challenges were identified for both teachers and students. In addition, a variety of pedagogical strategies were recommended by teachers from their own practice. In categorising approaches taken by teaching to support students five key themes emerged: unplugged type activities, contextualisation of tasks, collaborative learning, developing computational thinking, and scaffolding programming tasks. Further investigation could support whether these strategies can alleviate the challenges of teaching and learning of Computing for students and teachers. In particular developing student resilience in Computing is seen as a challenge while not many strategies are suggested. The results of this study will be useful for teachers who are new to the teaching of Computing.
Association of removable partial denture use with oral and systemic health.

OBJECTIVES
This narrative literature review aims to consider the impact of removable partial dentures (RPDs) on oral and systemic health.


DATA AND SOURCES
A review of the literature was performed using Medline/PubMed database resources up to July 2011 to identify appropriate articles that addressed the objectives of this review. This was followed by extensive hand searching using reference lists from relevant articles.


CONCLUSIONS
The proportion of partially dentate adults who wear RPDs is increasing in many populations. A major public health challenge is to plan oral healthcare for this group of patients in whom avoidance of further tooth loss is of particular importance. RPDs have the potential to negatively impact on different aspects of oral health. There is clear evidence that RPDs increase plaque and gingivitis. However, RPDs have not clearly been shown to increase the risk for periodontitis. The risk for caries, particularly root caries, appears to be higher in wearers of RPDs. Regular recall is therefore essential to minimise the risk for dental caries, as well as periodontitis. There is no evidence to support a negative impact on nutritional status, though research in this area is particularly deficient. Furthermore, there are very few studies that have investigated whether RPDs have any impact on general health. From the limited literature available, it appears that RPDs can possibly improve quality of life, and this is relevant in the era of patient-centred care. Overall, further research is required to investigate the impact of RPDs on all aspects of oral and general health, nutritional status and quality of life.
