A Novel Control Scheme for Wind Turbine Driven DFIG Interfaced to Utility Grid

This article deals with a phase-locked loop (PLL)-based novel control for wind turbine driven doubly fed induction generator interfaced to utility grid with a battery energy storage (BES) connected at the dc link. The control of grid-side converter (GSC) is modified to export/import constant power to/from the grid. The state of charge of BES helps in deciding the reference export power to the grid apart from the manual selection using averaged wind power in a particular period of time. An off maximum power point tracking logic is incorporated in the rotor-side converter (RSC) control to operate the BES within its constraints and, moreover, to feed constant power to the grid. In addition, the energy management scheme of the system is presented in the form of flowchart for both exporting and importing power to/from the grid. The RSC and GSC have taken care of unity power factor operation at stator terminals and to mitigate harmonics and grid currents balancing, respectively. The system performance is found robust as the PLL response is not affected even under grid voltages with dc offset. The system is modeled and simulations are carried out in MATLAB using SimPowerSystems tool box. Moreover, the control scheme performance is compared with conventional control algorithms both in terms of PLL and converter controls. To validate the effectiveness of the control scheme, a prototype of the system is developed. Test results demonstrate the satisfactory performance of the system under various operating conditions.
Hybrid Reconstruction of Subsurface 3-D Objects Using FRTM and VBIM Enhanced by Monte Carlo Method

A hybrid method is proposed to reconstruct the subsurface 3-D objects with electromagnetic fields. The frequency-domain reverse time migration (FRTM) is first used to determine the approximate locations and sizes of the objects. Then, based on these results, the full-wave inversion, the variational Born iteration method (VBIM) is used to reconstruct both the shapes and dielectric parameters of the objects. The Monte Carlo method (MCM) is adopted to further refine the reconstructed shapes. Numerical simulations show that the proposed hybrid method can be effectively used for the subsurface imaging and detection.

Implementasi Google Maps API Pemetaan Jalur Evakuasi Bencana Alam di Kabupatem Lombok Utara

Basically, Indonesia is traversed by three active tectonic plates namely the Indo-Australian Plate in the south, and the Eurasian Plate in the north and the Pacific Plate in the east. The plates collide with each other because the Indo-Australian Plate movement drops below the Eurasian plate. As a result of this accumulation, it caused earthquakes, volcanoes, and faults or faults in parts of Indonesia. In the Geographic Information System evacuation routes will be used by Google maps Api to implement the spatial map making of evacuation routes. Google Map Api is an application interface that can be accessed via javascript so that Google Map can be displayed on the web page that we are building. The result or output to be achieved is the creation of a geographic information system mapping natural disaster evacuation route in the North Lombok district that can be run on a Web platform. Based on the trials conducted it can be concluded that this application can help the community to find the location of evacuation routes and gathering points in accordance with the districts and villages where they live.
Obstructive sleep apnea and non-sustained ventricular tachycardia in patients with advanced chronic kidney disease and mild left ventricular dysfunction

Purpose: We conjectured that obstructive sleep apnea (OSA) is associated with an increased risk of ventricular arrhythmias freely of other risk issues and that the harshness of OSA is directly allied with the extent of this risk. In this curent study, we assessed the effects of clonazepam and zolpidem in OSA in patients with advanced chronic kidney disease (CKD) and mild left ventricular (LV) dysfunction. Methods: This transversal study involved 30 patients with CKD stage 4, fifteen of them using clonazepam 2 mg and the other 15 patients using zolpidem 10mg before to sleep due to a disturbance to sleep. Results: During the polysomnography, the group using clonazepam 2 mg showed a higher apnea/hypopnea index events (47.3 ± 6.5 events/hour) in comparison with the group using zolpidem 10 mg (10.4 ± 3.3 events/hour), P<0.0001. The 24-hour Holter monitoring presented a mean number of non-sustained ventricular tachycardia (NSVT) during the day, night, and whole period, respectively of 3.1 ± 1.9, 18.2 ± 2.1, and 10.7 ± 2.0 for the subjects using 2 mg of clonazepam, as well as, 9.4 ± 2.5, 3.3 ± 1.5, and 6.3 ± 1.8 for the individuals using zolpidem 10 mg (all the comparisons between groups into the same period were significant, P<0.0001 for all of them). Conclusion: There were the highest number of AHI events in patients using clonazepam 2 mg than in those using zolpidem 10 mg, as well as, a major incidence of NSVT in the first group compared to the second one, during the whole period recorded by the 24-hour Holter monitoring.

The Relevance of Remittances on Economic Growth in Tanzania

Despite the increasing importance of remittances in total international capital flows, the relationship between remittances and economic growth has not been adequately addressed, especially in Tanzania. This article, therefore, explores the aggregate impact of remittances on economic growth from 1985 to 2017. The Autoregressive Distributed Lag Model is used for time series estimation. Employing the general to specific technique, the article reveals that remittances have a positive and significant effect on economic growth in the country. It also reveals that foreign direct investment and terms of trade have a robust and significant influence on economic growth. However, exchange rates happened to have a negative impact on economic growth in Tanzania. It is therefore being recommended that policy-makers should endorse initiatives to attract huge amounts of personal remittances in the country in order to continue achieving the positive long-run relationship between remittances and economic growth. Also, they should pay more attention to policies that help to engage the diaspora for the development of the country. In this regard, the government ought to establish innovative schemes to trap the diaspora's cash. Keywords : Economic Growth, Remittances, ARDL, Tanzania
Decentralized Bioinspired Non-Discrete Model for Autonomous Swarm Aggregation Dynamics

In this paper a microscopic, non-discrete, mathematical model based on stigmergy for predicting the nodal aggregation dynamics of decentralized, autonomous robotic swarms is proposed. The model departs from conventional applications of stigmergy in bioinspired path-finding optimization, serving as a dynamic aggregation algorithm for nodes with limited or no ability to perform discrete logical operations, aiding in agent miniaturization. Time-continuous simulations were developed and carried out where nodal aggregation efficiency was evaluated using the following metrics: time to aggregation equilibrium, agent spatial distribution within aggregate (including average inter-nodal distance, center of mass of aggregate deviation from target), and deviation from target agent number. The system was optimized using cost minimization of the above factors through generating a random set of cost datapoints with varying initial conditions (number of aggregates, agents, field dimensions, and other specific agent parameters) where the best-fit scalar field was obtained using a random forest ensemble learning strategy and polynomial regression. The scalar cost field global minimum was obtained through basin-hopping with L-BFGS-B local minimization on the scalar fields obtained through both methods. The proposed optimized model describes the physical properties that non-digital agents must possess so that the proposed aggregation behavior emerges, in order to avoid discrete state algorithms aiming towards developing agents independent of digital components aiding to their miniaturization.
Workplace digitalisation and work-nonwork satisfaction: the role of spillover social media

ABSTRACT Prior research has shown that the use of Information Communication Technology (ICT) outside work hours blurs work and nonwork boundaries, exacerbates work-life conflict, and negatively impacts employees’ satisfaction. Conversely, personal ICT-use at work, or cyberloafing, has become an increasing concern among employers given its putative impact on individual and organisational performance. We use the ‘dual-lens’ of Boundary theory and Set theory to conceptualise employees’ work-related ICT-use outside work hours and cyberloafing as a set-theoretic phenomenon reflecting ‘spillover social media’. Drawing on a survey of 403 Australian white-collar employees and using a set-theoretic approach (fsQCA), we discuss the following findings. First, spillover social media positively impacts work satisfaction among people who are single and do not have children. Second, spillover social media positively contributes to nonwork satisfaction among married male participants who do not have children. Third, that parents only reported nonwork satisfaction if they did not engage in spillover social media.
Shedding new light on nostalgia: The origins, consequences and buffering capacity of nostalgia

Nostalgia, a sentimental longing for the past, has several psychological effects. For example, it increases self-continuity, meaning in life, and optimism. Nostalgia also buffers the adverse impact of psychological threats, such as death thoughts or the potential meaninglessness of life. In this thesis, I have expanded upon this existing nostalgia research in three keys ways. In my first empirical paper, I conducted three studies to investigate the, previously undocumented, link between nostalgia and spirituality. In Study 1, nostalgia was related to greater spirituality. In Study 2, nostalgia was again related to greater spirituality, and this relation remained significant after controlling for key demographics and core personality traits. In Study 3, nostalgia fostered spirituality via selfcontinuity and meaning in life serially. Taken together, nostalgia is associated with, and fosters, spirituality through its effect on self-continuity and meaning in life. In my second empirical paper, I investigated an additional psychological threat against which nostalgia may buffer: life uncertainty. Specifically, I examined whether nostalgia buffers the negative effect of life uncertainty on self-continuity. The findings revealed that life uncertainty reduced self-continuity, but only for participants low in nostalgia proneness, not those high in nostalgia proneness. Furthermore, life uncertainty reduced selfcontinuity, but only for those who recalled a recent autobiographical event, not those who recalled a nostalgic event. Thus, nostalgia buffers the negative effect of self-continuity on life uncertainty. In my third empirical paper, I investigated the origins of nostalgic memories in three studies. In particular, I examined whether savouring is implicated in the formation of nostalgic memories. I also examined whether nostalgia for a previously savoured experience predicts optimism for the future. In Study 1, retrospective reports of having savoured a specific event were associated with greater nostalgia for it. In Study 2, retrospective reports of savouring a time period were associated with greater nostalgia for that time period. In Study 3, savouring an experience predicted nostalgia for it 4-9 months later. Lastly, in Studies 2-3, nostalgia for a savoured experience was associated with greater optimism. In all, savouring provides a foundation for nostalgic memories and an ensuing optimism.

Physical therapy of far-advanced primary lower limb lymphedema: a case report and literature review

Physical therapy with good compliance remains the key of success in lymphedema management. Tissue excisions should be reserved for physiotherapy-resistant cases and always followed by extended maintenance compression therapy. We present the case of the successful physical therapy of the young female with a neglected, massive, primary lymphedema of the lower extremity present since birth, with prior extensive tissue resection. Complex decongestive physical therapy has been performed for one year, combined with ten months’ of negative-pressure wound therapy at a hospice facility due to pressure ulcers complication. Obtained reduction of the affected extremity/edema volumes (by 69.4 and 88.2% respectively) enhanced patient’s mobility, helping her become more independent. Ongoing therapeutical program maintained these results for three years. Physical therapy even in far-advanced and neglected cases may be effective. Lymphedema services should be offered widely through a network of fully reimbursed health care system, delivering high-quality evidence-based management tailored to individual patients.
Inadvertent migration of hepatic artery pseudoaneurysm coil during endoscopic retrograde cholangiopancreatography

We report a case of a 72-year-old male with a cascade of complications being diagnosed as an acute cholecystitis. The cascade includes iatrogenic pulling of coils, which were placed for treatment of right hepatic artery pseudoaneurysm, into the common bile duct (CBD) in an attempt for removal of the misplaced/migrated CBD plastic stent inserted by endoscopic retrograde cholangiopancreatography (ERCP). The case demonstrates a series of mishaps leading to a rare complication of iatrogenic migration of transarterial coil in the gastrointestinal tract. This could be the first case of coil migration as a complication of ERCP due to suboptimal stenting/removal techniques.
Impact of land use changes on soil quality and species diversity in the Vindhyan dry tropical region of India

Abstract Conversion of forest land into different land use types is the primary cause of degradation of land resources, which in turn alters nutrient and carbon cycles, land productivity and diversity of species. There is scarcity of information about land-use changes (LUC) and their effect on relationship of soil quality and species diversity at landscape level in the Vindhyan dry tropical region. We evaluated the impact of land-use changes on soil physicochemical quality and the influence of these qualities on species diversity and organic matter accumulation. We also established the relationship between soil quality indicators and species diversity parameters. To examine impact of LUC, we did a detailed field survey and analysed selected soil quality indicators by standard methods. We examined species diversity parameters and established the relationship between soil quality and species diversity. We found that there is a marked decline in soil porosity, water-holding capacity and soil moisture due to LUC. Conversion from forest land (FL) to savanna land (SL) resulted in soil organic carbon decreasing by ∼40–50%. The decrease was more pronounced in cultivated land (CL) and degraded land (DL) (65–70% and 83–85%, respectively). In the case of total N, maximum decrease in total N of 83–87% was noted in DL as compared with FL. The poor soil quality indicators in degraded and agricultural land can be explained by the interaction between the soil organic carbon and nitrogen loss with diversity loss. This study recommends that for management/restoration of land resources, planning strategies should consider the current landscape structure, with land-use planning.
Semantic analysis framework for protecting the power grid against monitoring-control attacks

The pervasive use of heterogeneous and non-proprietary information and communication technology exposes the power grid to cyber-attacks. In particular, monitoring-control attacks (MCA), which manipulate control decisions by fabricating measurements, are highly threatening, because MCA are difficult to detect and can coordinately inflict severe consequences at a large scale. To defend against MCA, a semantic analysis framework is proposed in complement to direct-setting intrusion detection. The proposed framework has the advantages of promising runtime and detection performance. The performance of the proposed framework is evaluated under different attack scenarios and compared with a direct-settings intrusion detection systems using a 6-bus test system and the New-England 39-bus test system.
What explains vast differences in jumping power within a clade? Diversity, ecology and evolution of anuran jumping power

: 12 1. Anuran (frog and toad) jumping power varies greatly across species, yet muscle power does 13 not. Given that the jumping power of some species is up to five times higher than typical muscle 14 power, power amplification by elastic elements is suggested to explain this discrepancy. 15 However, the ecological reasons for this variation in jumping power are unclear. One hypothesis 16 is that small jumpers are limited by the time available to accelerate their body during take-off, 17 leading to small species needing greater power production than larger species to achieve similar 18 jumping performance. Another (non-mutually exclusive) hypothesis is that the microhabitat 19 species inhabit may drive variation through trade-offs with performance in microhabitat-specific, 20 non-jumping behaviors. 21 2. We compared jumping power across 68 anuran species that were diverse in evolutionary 22 relationships, microhabitat use, and body mass. We used phylogenetic comparative methods to 23 compare the role of microhabitat and body mass in explaining variation in jumping power across 24 species. 25 3. We found the strongest support for a model that included two factors and their interaction. 26 First, as body mass increased, jumping power decreased. Second, species that burrowed showed 27 lower jumping power than species that did not burrow. Third, the interaction between body mass 28 and burrowing behavior showed that jumping power declines more rapidly with body mass in 29 burrowing species than non-burrowing species. All 4. The effect of body mass suggests that interspecific variation in jumping power might be partly 31 explained by scaling relationships. Anurans with small body mass may be able to achieve similar locomotor performance (e.g. takeoff velocity) as those with larger body mass, by more 33 effectively amplifying muscle power. Additionally, the effect of burrowing behavior suggests 34 that species that use hindlimbs to burrow may experience a reduction in their ability to generate 35 jumping power. This may indicate a functional trade-off between jumping and burrowing 36 performance.
Knowledge, attitude and practices about tetanus toxoid immunisation amongst general population of an urban semi-slum area: a cross-sectional interview-based study from Western India

Background: Members of the public are frequently unaware of tetanus immunisation schedules and its importance in preventing tetanus. This community-based, cross-sectional, complete enumeration, interview-based study was conducted to assess the knowledge, attitude and practices about tetanus toxoid immunisation amongst the general population in an urban semi-slum area located about 30 kms from Mumbai city in Western India. Methods: Respondents comprised adult residents of either sex, who gave written informed consent to participate in the study. After obtaining approvals, the study was explained during routine home visits and the respondents were interviewed at a time convenient to them. A direct face-to-face interview was conducted using a semi-structured proforma and their responses were recorded and statistically analysed. Results: Of the 161 participants (90 males; 71 females), 16.15% were illiterates. 95.65% thought that a single tetanus toxoid injection was adequate to prevent tetanus while none knew that pregnant women are immunised to protect newborns against tetanus. 67.08% were unaware about the need for maintaining cold chain for storage of tetanus toxoid. 96.89% had received only one injection of tetanus toxoid, irrespective of the type of injury or previous immunisation status. The belief that an adult requires tetanus toxoid after every injury exhibited education-wise significant difference (p=0.02). Conclusion: Sustained and focussed health education efforts are necessary to combat misconceptions regarding tetanus toxoid immunisation.
A MaxSAT-Based Framework for Group Testing

The success of MaxSAT (maximum satisfiability) solving in recent years has motivated researchers to apply MaxSAT solvers in diverse discrete combinatorial optimization problems. Group testing has been studied as a combinatorial optimization problem, where the goal is to find defective items among a set of items by performing sets of tests on items. In this paper, we propose a MaxSAT-based framework, called MGT, that solves group testing, in particular, the decoding phase of non-adaptive group testing. We extend this approach to the noisy variant of group testing, and propose a compact MaxSAT-based encoding that guarantees an optimal solution. Our extensive experimental results show that MGT can solve group testing instances of 10000 items with 3% defectivity, which no prior work can handle to the best of our knowledge. Furthermore, MGT has better accuracy than the LP-based approach. We also discover an interesting phase transition behavior in the runtime, which reveals the easy-hard-easy nature of group testing.
