Analysis and Comparison of Conventional and Interleaved DC/DC CUK Converter using Fuzzy Logic Controller

Conventional DC-DC converters are widely used in non-conventional power conversions namely in solar and wind power generation systems. Since there is no filter inductor on output side, output current of cuk converter is pulsed, which is not desirable, so it is required to improve the quality of power when DC-DC converters are employed for transferring requisite amount of power. The objective of this paper is to analyze, simulate and examine the operation of interleaved cuk converter and to compare with conventional cuk converter using Fuzzy logic controller. The unwanted ripple content is diminished and reduction in settling time by implementing interleaved structure to cuk converter topology with current and voltage feedback control loop by using fuzzy logic controller. In this paper the proposal model gives high efficiency and gain with limited duty cycle and wide load variation range. The performance of this system is observed in MATLAB/SIMULINK SOFTWARE.
Comparison of open circuit voltage generated by tracking solar panel and static solar panel using arduino board

This paper represents the comparison of the voltages generated by the tracking and static solar panels. The work also aims to design and fabrication of a cheap and efficient tracking device. This device comprises of hardware and software. A rigid mechanical structure with nut and screw as the transmission is developed. 4 LDRs and DC motors are employed, which are cheap and less power consuming. As far as the software concerns, an open source microcontroller “Arduino UNO” board is used because of their simplicity and cost effectiveness. This Sun tracking device with a PV panel installed on it, is placed outside at the roof of the building along with a static solar panel. Output voltages generated from both panels are recorded in SD card through data logger in Arduino UNO. This real-time data shows the difference in amplitude of both the signals. Voltage of rotating panel is more than static one resulting that the tracking device can increase the efficiency of the panel by exposing the PV panel more to the sun light. Hence this setup proves that the solar panel with tracking system generates more energy than solar panel without tracking system.&#x0D; Keywords: Solar Tracker, LDR, PV Panel, Arduino UNO Board.

Designing a Structured System for Mammography Reporting

Background: Breast cancer is among the top causes of cancer-related mortality among females in both developed and developing countries. Screening for breast cancer plays a crucial role in the prevention of disease burden. Among various imaging modalities, mammography is currently considered the first step for the detection of breast lesions. The mammography data of breast cancer patients encompass a wide array of texts related to specific visual findings. Accordingly, unorganized mammography documents usually impede physiciansâ efforts to fully review the previous information in follow-up visits; hence, this not only affects clinical judgment and treatment planning adversely, but also adds to the financial burdens and workload imposed on the healthcare system. This further highlights the great potential of structured mammography reporting in the management of breast cancer patients. Methods: In the first step, an expert panel consisting of two attending radiologists and a health informatician (all affiliated to the Shiraz University of Medical Sciences, Shiraz, Iran) reviewed related guidelines to determine the appropriate items, ontologies, and standard formats for data entry. These included radiology textbooks and the systematized nomenclature of medicine (SNOMED). In addition, 100 mammography reports were completely examined for data extraction and the creation of a template report. In the next step, the structure of the data registry was discussed among a group of radiologists and breast cancer surgeons during several sessions using Delphi technique. Results: Overall, 119 fields were selected for data entry. Our survey showed that all of the contributing physicians believed that a structured reporting system for mammography can help standardize and reduce reporting time and errors. Following the completion of the template, a user interface was developed by the expert panel for integration in the cloud software workflow, which will be deployed and assessed in the next phase of the project. Conclusion: Structured mammography reporting helps radiologists and surgeons to efficiently and confidently track the management course of their patients. In addition, with the advancement of artificial intelligence, especially deep learning for image classification, clean and labeled image databases can be used for designing computer-assisted decision support systems without significant data preprocessing.
Business Policy Violation in Web Service Integration of QoS-Aware Web Service using Hybrid Genetic Algorithms for Security in SOA

The Web services advanced as a pretty good paradigm for publication, service consuming and discovering.The aspects of Service-Oriented Architecture (SOA) are broadly engaged in e-government, e-business, process control, finance, multimedia services, automotive schemes, and many other domains.A Quality-of-Service (QoS) remains as useful for working towards relating to the non-functional principles to the Web services, and then it is employed by way of a significant distinguishing point to the various Web services.Through this incidence, the Web services on the web, the QoS management becomes furthermore essential.Though confident of them are suited a standard, no particular acceptable performance standard maintained by the frameworks of the web services.Additionally, the enforcement of the performance of the existing scheme is generally concerned through service provider besides hardly concerned by the network and the consumer environment.Because of this reason, hybrid Genetic Algorithms (HGAs) used to solve the problems based on QoS service composition.With the help of the proposed method an Adaptive and Secure Service Composition engine (ASSC), proceeds a benefit to an effective heuristic way of the Algorithm to make optimum service compositions in the SOA aspects

Study the Best PenTest Algorithm for Blind SQL Injection Attacks

&lt;p&gt;There are several types of SQL injection attacks. One of the most popular SQL Injection Attacks is Blind SQL. This attack is performed by exploiting a gap in the database server when executing query words. If the server responds to an invalid query, the attacker will then reverse the engineering part of the SQL query, which is obtained from the error message of the server. The process of generating a blind SQL injection attack is complicated. As a result, a Pentester often requires a long time to penetrate the database server. This research provides solutions to the problems above by developing the automation of a blind SQL injection attack. The method used in this research is to generate keywords, such as the database name and table name so that the attacker can retrieve information about the user name and password. This research also compares several search algorithms, such as linear search, binary search, and interpolation search for generating the keywords of the attack. Automation of the Blind SQL Injection was successfully developed, and the performance of the keywords generation for each algorithm was also successfully measured, i.e., 1.7852 seconds for Binary Search, 1.789 seconds for interpolation and 1.902 seconds for Linear Search.&lt;/p&gt;

Emotions in Online Reviews and Product Sales: Unifying Empirical and Theoretical Perspectives

Emotion artificial intelligence, the algorithm that recognizes and interprets various human emotions beyond valence (positive and negative polarity), is still in its infancy yet attracts much attention from both the industry and the academia. Based on the discrete emotion theory and statistical language modeling, this work proposes an algorithm to enable automatic domain-adaptive emotion lexicon construction and multi-dimensional emotion detection in texts. With a large-scale dataset of China’s movie market from 2012 to 2018, we construct and validate a domain-specific emotion lexicon and demonstrate the predictive power of eight discrete emotions (i.e., surprise, joy, anticipation, love, anxiety, sadness, anger, and disgust) in online reviews on box office. Further, we find that representing emotions using discrete emotions yields higher prediction accuracy than using valence or latent emotion variables generated by topic modeling. To understand the source of the predictive power from a theoretical perspective, and to test the cross-culture generalizability of our prediction study, we further conduct an experiment in the U.S. movie market, based on the “feelings as information” theory and theoretical research on emotion, judgement, and decision making. We find that mediated by processing fluency, discrete emotions significantly affect the perceived review helpfulness, which further influences purchase intention. Our work shows the economic value of emotions in online reviews, generates insight into the mechanism of their effects, and has managerial implications for online review platform design, movie marketing, and cinema operations.

Variation of Solar Radiation in Akwanga, Nasarawa State, Nigeria

One of the major environmental problem is the long-term changes in the Earth’s climate. In this study, the variation of solar radiation for Akwanga zone, Nasarawa State, Nigeria were determined. Twelve locations were carefully selected where there is no sunshine and wind obstruction. Three 12V, 5W Solar panels (poly) were used and a three-hour daily measurement interval (12.00 pm to 3.00 pm) was made using the Secondary Standard Pyranometer placed on the top of the panels. Angstrom-Prescott Regression Equation was used to estimate the output. The continuity in the assembled system was measured using an Avometer. The result revealed that the highest monthly average daily global solar radiation was observed in the month of April (25.2 MJ/m2) followed by June (22.94 MJ/m2), and march (22.42 MJ/m2), while the lowest was observed in the month of August (12.04 MJ/m2) followed by July (13.57 MJ/m2), and September (14.26 MJ/m2) in the locations selected. The solar radiation intensity was found to range from 156.44 W/m2 to 293.84 W/m2 with the mean value of 220.04 W/m2. The highest total global solar radiation value of 25.2MJ/m2 was observed in April while the lowest value of 12.04 MJ/m2 was observed in October. The extraterrestrial solar radiation were found to range from 16.72 MJ/m2 in March to 29.90 MJ/m2 in April with average value of 22.89MJ/m2. The atmospheric transmission coefficient over the year is found to range from 0.5 in July and October to 1.3 in June and October. The investigation reveal that there is bright sun shine in the study area which confirms high atmospheric transmission coefficient or clearness index throughout the year in this study.

Optimization from Structured Samples for Coverage Functions

We revisit the optimization from samples (OPS) model, which studies the problem of optimizing objective functions directly from the sample data. Previous results showed that we cannot obtain a constant approximation ratio for the maximum coverage problem using polynomially many independent samples of the form {S_i, f(S_i)}_{i=1}^{t} (Balkanski et al., 2017), even if coverage functions are (1-\epsilon)-PMAC learnable using these samples (Badanidiyuru et al., 2012), which means most of the function values can be approximately learned very well with high probability. In this work, to circumvent the impossibility result of OPS, we propose a stronger model called optimization from structured samples (OPSS) for coverage functions, where the data samples encode the structural information of the functions. We show that under three general assumptions on the sample distributions, we can design efficient OPSS algorithms that achieve a constant approximation for the maximum coverage problem. We further prove a constant lower bound under these assumptions, which is tight when not considering computational efficiency. Moreover, we also show that if we remove any one of the three assumptions, OPSS for the maximum coverage problem has no constant approximation.
