A Voltage Controller in Photo-Voltaic System with Battery Storage for Stand-Alone Applications

This paper proposes the new voltage controller in photo-voltaic system for Stand-Alone Applications with battery energy storage. The output of the PV array is unregulated DC supply due to change in weather conditions. The maximum power is tracked with respect to temperature and irradiance levels by using DC-DC converter. The perturbation and observes algorithm is applied for maximum power point tracking (MPPT) purpose. This algorithm is selected due to its ability to withstand against any parameter variation and having high efficiency. The solar cell array powers the steady state energy and the battery compensates the dynamic energy in the system. The aim of the control strategy is to control the SEPIC converter and bi-direction DC-DC converter to operate in suitable modes according to the condition of solar cell and battery, so as to coordinate the two sources of solar cell and battery supplying power and ensure the system operates with high efficiency and behaviors with good dynamic performance. The output of DC-DC converter is converted to AC voltage by using inverter. The AC output voltage and frequency are regulated. A closed loop voltage control for inverter is done by using unipolar sine wave pulse width modulation (SPWM). The regulated AC voltage is fed to AC standalone loads or grid integration. The overall system is designed, developed and validated by using MATLAB-SIMULINK. The simulation results demonstrate the effective working of MPPT algorithm, control strategy and voltage controller with SPWM technique for inverter in AC standalone load applications.
An Anisotropic Model for Annulus Tissue and Enhanced Finite Element Analyses of Intact Lumbar Disc Bodies

The current investigation addresses advanced FE analyses of intact lumbar intervertebral discs. Human disc body units basically consist of a fluid filled cavity (nucleus pulposus) approximately at the disc center and surrounding annulus tissue reinforced by collagen fibers (annulus fibrosus). For the latter component a constitutive model is presented which accounts for nonlinear anisotropic stress response. In contrast to state-of-the-art material descriptions mostly used in the literature (linear elasticity), the current approach provides numerical accuracy in the finite strain regime. Thus, local strain and stress distributions in the annulus fibrosus can properly be determined. Because of the highly nonlinear stress response of the constitutive equations, nonlinear material parameters are required. Although tensile properties of the human annulus fibrosus can already be found in the literature, these material data are not suitable for the current concept as will be shown. The entire constitutive theory is therefore based on a new experimental procedure for the determination of local, nonlinear and anisotropic stress response in annulus tissue. The constitutive model proves its applicability in representative numerical examples. In contrast to state-of-the-art FE analyses, the results do not exhibit parasitic strain (and stress) distributions in annulus tissue under physiological loading conditions. Hence, the current approach seems to be very attractive for refined spinal implant design.
PERSONAL HYGIENE AND REPRODUCTIVE HEALTH KNOWLEDGE AMONG ADOLESCENTS AT KAMPUNG BELAJAR, SURABAYA

Health knowledge is fundamental for everyone, including children. This knowledge provides understanding for children in preparation for entering puberty. However, health education which discusses personal hygiene, anemia, puberty, and healthy relationships, as well as reproductive health is still very limited in formal schools. Because of these limitations, children need to get informal education. One of the ways this is done is through health education activities at Kampung Belajar. The research objective was to analyze health knowledge on personal hygiene, anemia, puberty, healthy relationships, and reproductive health taught through health education at Kampung Belajar in Jambangan, Surabaya. This study used secondary data sources obtained from the teaching team at the learning village. The data obtained were the result of evaluating learning activities related to health knowledge. The research subjects were 22 students from grade 1 to 7. The results of this study were 0.031 with p < 0.05. It can be concluded that there was a difference in health knowledge, which included personal hygiene, anemia, puberty, healthy relationships, and reproductive health in the study group after receiving health education provided by the teaching team at Kampung Belajar.
A Computational Study for Biological Flapping Wing Flight

A computational model for unsteady aerodynamics of a flapping wing has been developed based on the strip theory, which makes use of the concept of dividing the wing into a number of thin strips. This enables us to study the wing as a set of airfoi1s next to one another by assuming no crossflow between them. Wing kinematics including normal and chordwise force calculations was considered to calculate average lift, thrust, power requirements and propulsive efficiency for a flapping wing in flight. In addition, an optimization procedure was developed for obtaining maximum propulsive efficiency within the range of possible flying conditions. Computations were performed on a mechanical flying Pterosaur replica as wel1 as smal1er biological species including the Corvus monedula, Larus canus and Columba livia, which makes use of the vortex gaits. The effect of aerodynarmic parameters on the performance of these biological flight vehicles was studied. It was found that the propulsive efficiency of al1 species considered were around 65-75% whereas the lift and thrust varied largely depending on the weight, flapping frequency and flight speed of the species. The range of dynamic twist for sustainable flying conditions (Lift＞Weight) also varied for different species, becoming smal1er as the size of a bird increases.
Effects of phase-to-intensity noise conversion by multiple reflections on gigabit-per-second DFB laser transmission systems

Large power penalties and bit-error-rate floors have been observed in some Gb/s systems using distributed feedback (DFB) lasers, which could be attributed to interferometric conversion of laser phase noise to intensity noise by multiple reflections at connectors and splices. The authors calculated the power spectral density of the interferometric noise and its impact on system performance as a function of both the magnitude and number of reflections, and they compare the theoretical predictions with experimental results. Their studies indicate that connectors and splices with return losses of more than about 25 dB are required for the reliable operation of Gb/s fiber transmission systems, even if optical isolators are used. >
Leadership Styles in Architectural Design Offices in Turkey

AbstractThe quality of a project depends on the performance of the design team; design faults can be prevented by effective team management. In this context, effective leadership is needed to enable effective team management. The preference for more than one style of leadership is inevitable in complex business life because different styles are contingent on different situated contexts. This paper focuses on determining which of the two leadership styles architects predominantly prefer in Turkey, and whether there are any differences in the preferences of leadership styles between the design and production phases in a construction context. Data were collected through a questionnaire on leadership styles, which was distributed to 40 architects from different design offices in Turkey. The leadership styles are gathered into two primary groups: transactional and transformational leadership styles. Two styles fall under transactional leadership—coercive and authoritative—and four styles fall under transformat.

A Review of Geosynthetic Liner System Technology

This paper presents a general review of geosynthetic liner systems design considerations. The paper emphasizes the fundamental differences between a liner and a liner system, discusses the types of liner systems that are effective in landfill applications, and discusses how the components of a liner system may vary depending on the type of application, regulatory requirements, site hydrogeologic and climatic conditions, and the availability of materials. Regarding regulatory considerations, the paper discusses how liner systems must be selected and designed in conformance with regulatory performance standards in order to ensure long-term protection of the environment, and notes that many American state regulations for municipal waste landfills include minimum design guidelines that may be inadequate to meet the state's performance standards. The two aspects of chemical compatibility—retention and resistance to chemical attack—are discussed, and a generalized approach to designing geosynthetic liner systems is presented. The paper concludes with a discussion on future needs of the discipline and the industry.
Elevated Cardiopulmonary Complications after Revascularization in Patients with Severe Mental Health Disorders.

Introduction Mental health disorders (MHD) are prevalent within surgical patient populations and can be associated with poorer postoperative outcomes, particularly in those with more severe MHD (schizophrenia and bipolar disorder). However, these associations have not been examined in vascular surgery patients. This study investigated patients undergoing lower extremity revascularization, hypothesizing that those with severe MHD would experience worse health and postoperative outcomes. Methods A retrospective chart review of patients from 2010-2015 with peripheral arterial disease (PAD) requiring revascularization was conducted, with subsequent narrowing to those with concurrent MHD diagnoses, including severe MHD (sMHD) defined as bipolar disorder or schizophrenia and non-severe MHD (nsMHD), defined as anxiety or depression. The primary endpoints were 30-day mortality; Major Adverse Limb Events (MALE) including amputation at the above or below knee level; and Major Adverse Cardiac Events (MACE) including myocardial infarction (MI), congestive heart failure (CHF) exacerbation, and arrhythmia. Secondary endpoints were readmission within 30 days, pulmonary complications, and wound infection. Statistical analyses included Fisher Exact Test and Student's T-test. Results Eighteen patients with MHD (sMHD, n=10; nsMHD, n=8) were identified and stratified. Twenty-four limbs were revascularized (sMHD, n=13; nsMHD, n=11). Overall incidence of 30-day mortality, MALE, and MACE were 4.2%, 33.3%, and 50.0%, respectively. Readmission rate, pneumonia, and wound infection occurred in 41.7%, 20.8%, and 16.7% of the population. Stratifying by MHD severity, no significant differences were observed for medical comorbidities, MALE, intervention type (open vs. endovascular), or treatment indication (claudication vs. critical limb ischemia). Patients with sMHD had significantly higher rates of MACE compared to patients with nsMHD (30.8% vs. 18.2%, p<.05). Pneumonia was also more prevalent in this group (38.5% vs. 0.0%, p<.05). Conclusion While patients with concurrent diagnoses of MHD and PAD presented with similar comorbidities, comparable disease severity, and were equally treated by open versus endovascular techniques, those with severe MHD suffered significantly elevated rates of cardiopulmonary complications, specifically MACE and pneumonia. Further investigation is warranted to identify opportunities to optimize post-operative care for these complex patients.

A Progressive Single-Image Dehazing Network with Feedback Mechanism

In the past decade, deep learning methods, especially convolutional neural networks, have received much attention in applications of single-image dehazing. However, the haze in hazy images cannot be distinctly separated because it is complicatedly mixed with the background components. If we roughly remove the haze, the background tone of global atmospheric light may also be destroyed. To resolve the above problem and reconstruct clearer and higher-quality dehazing images, we introduced our progressive feedback progressive network (PFBN) in recurrent structure ties with a feedback mechanism. The feedback mechanism is implemented by stacking feedback blocks that contain feedback connections among iterations. At the input layer of each feedback block, its hidden state in the last iteration is delivered by a feedback connection to the present block as part of the input. The last hidden state, also referred to as high-level information, is fused with low-level information output by the previous block to generate effective feature representation. Moreover, we proposed an enhancement self-ensemble strategy to decrease the random error of the network to reconstruct clearer dehazing images. Finally, we designed a series of extensive experiments to verify the outstanding performance of our method.
MITE circuits: the continuous-time counterpart to switched-capacitor circuits

Some new applications of a family of circuits using op-amps built with multiple-input translinear elements (MITE) circuits are discussed. These include weighted average circuits for resistive networks, defuzzifiers, FIRs, common-mode feedback networks, sigma-delta modulators, and fast digital converters (digital-analog and analog-digital). Some aspects of MITE circuits not reported before are discussed like gain-bandwidth tradeoffs and an analysis showing that the behavior of closed-loop MITE circuits is determined by accurately controllable capacitance ratios; to a first-order approximation it is not affected by the parasitic capacitances of the MOS transistor. From this point of view MITE circuits are considered here as the continuous-time counterpart to switched-capacitor circuits. Experimental results of two test chip prototypes are shown.

This paper aims to study the relationship between wood density (DBM) and diameter at breast height (DAP) in an E. camaldulensis base population, planted in April 1986, in Selvíria, Mato Grosso do Sul State. Twenty tive progenies were distributed in a randomized blocks design, with ten replications and one tree plot spaced 4.0 m x 4.0 m. Assessment at seven years old showed an average of 19,65 em and 0.666 g/cm' for DAP and DBM, respectively. Heritability, at family levei, were 0.49 for DAP and 0.55 for DBM. Genetic correlation response between these two traits was negative, therefore, selection aiming improvement of one trait will decrease the other one. Different breeding strategies should be used to improve both traits.
What empowers individuals and teams in project settings? A critical incident analysis

Purpose – Empowerment is a concept that means different things to different individuals. The factors that engender feelings of empowerment are thus multifarious. The purpose of this paper is to focus on to the factors that empower individuals and teams in projects settings.Design/methodology/approach – Using the critical incident technique (CIT), 122 critical incidents comprising 69 empowering and 53 disempowering experiences of 30 purposively selected construction professionals are elicited and analysed.Findings – Adopting a broad frame of reference on the premise that empowerment of individuals and teams in project settings is associated with drivers and barriers related to: the individual; the team context; the organisation; and the project – mutually exclusive and exhaustive contextual influences within each frame of reference are identified. At the individual‐level, cultural values and factors related to the quality of relationships with leaders and colleagues emerged. At the team‐level, team context.
Long distance migration is a major factor driving local adaptation at continental scale in Coho Salmon

Inferring the genomic basis of local adaptation is a long-standing goal of evolutionary biology. Beyond its fundamental evolutionary implications, such knowledge can guide conservation decisions for populations of conservation and management concern. Here, we investigated the genomic basis of local adaptation in the Coho salmon (Oncorhynchus kisutch) across its entire North American range. We hypothesized that extensive spatial variation in environmental conditions and the species’ homing behavior may promote the establishment of local adaptation. We genotyped 7,829 individuals representing 217 sampling locations at more than 100,000 high-quality RADseq loci to investigate how recombination might affect the detection of loci putatively under selection and took advantage of the precise description of the demographic history of the species from our previous work to draw accurate population genomic inferences about local adaptation. Results indicated that genetic differentiation scans and genetic-environment association analyses were both significantly affected by variation in recombination rate as low recombination regions displayed an increased number of outliers. By taking these confounding factors into consideration, we revealed that migration distance was the primary selective factor driving local adaptation and partial parallel divergence among distant populations. Moreover, we identified several candidates SNP associated with long distance migration and altitude including a gene known to be involved in adaptation to altitude in other species. The evolutionary implications of our findings are discussed along with conservation applications.
DIFFERENCE OF POWER TEST AND TYPE II ERROR (β) ON MARDIA MVN TEST, HENZE ZIKLER'S MVN TEST, AND ROYSTON'S MVN TEST USING MULTIVARIATE DATA ANALYSIS

The Mardia MVN test, Henze Zikler's MVN test, and Royston's MVN test are the most widely used tests to analyze multivariate normal (MVN) data, but there have not been many studies explaining the advantages and disadvantages of these tests. The research objective was to analyze the difference in test strength and type II (β) error in the Mardia MVN test, Henze Zikler's MVN test, and Royston's MVN test. The research data were analyzed using three MVN tests, namely the Mardia MVN test, Henze Zikler's MVN test, and Royston's MVN test. The results of the analysis in the form of test strength and type II error (β) would be compared at alpha (α) 1%, 5%, 10%, 15%, 20%, and 25%. The comparison results explained that the Mardia test had the greatest test strength and the smallest type II (β) error. The study concluded that the Mardia MVN test was a multivariate normal test better than Henze Zikler's MVN test and Royston's MVN test.
Research on Application of the Feature Transfer Method Based on Fast R-CNN in Smoke Image Recognition

Most of the existing smoke detection methods are based on manual operation, which is difficult to meet the needs of fire monitoring. To further improve the accuracy of smoke detection, an automatic feature extraction and classification method based on fast regional convolution neural network (fast R–CNN) was introduced in the study. This method uses a selective search algorithm to obtain the candidate images of the sample images. The preselected area coordinates and the sample image of visual task are used as network learning. During the training process, we use the feature migration method to avoid the lack of smoke data or limited data sources. Finally, a target detection model is obtained, which is strongly related to a specified visual task, and it has well-trained weight parameters. Experimental results show that this method not only improves the detection accuracy but also effectively reduces the false alarm rate. It can not only meet the real time and accuracy of fire detection but also realize effective fire detection. Compared with similar fire detection algorithms, the improved algorithm proposed in this paper has better robustness to fire detection and has better performance in accuracy and speed.
RISK PERCEPTION AND ATTITUDES IN ALBANIA: AN EXPLORATORY STUDY

This paper analyses risk perception and attitudes toward risk in Albanian society. It principally focuses on how age affects risk tolerance, even though also gender impact is taken into account. To particular interest is the shift in risk perception of the individuals before and after the fall of communism. The authors have embraced an exploratory research, using qualitative data from interviews. By considering two groups of participants, those older than 35 and younger than 35, the paper makes distinctions between risk attitude of both groups. In addition, the differences in responses between genders have been analyzed. The paper draws conclusions on the role of age and gender in relation to risk perception by aligning it with main conclusions of academic literature on these aspects. It further discusses the role of the social environment before and after the fall of communism and its effect on the risk tolerance profile of Albanians.
