An Indirect Approach to Forecast Produced Power on Photovoltaic Plants Under Uneven Shading Conditions

In this paper a forecasting method is proposed for the prediction of the generated power in photovoltaic systems. The approach exploits the combination of a virtual irradiance sensing methodology and a neural network forecasting system. The strength of this approach resides in its capability to support forecasting in presence of distributed shading patterns along the PV plant, without the necessity of external pyranometers or a complex data acquisition system. The technique was validated experimentally by forecasting the produced power on a PV array mounted on the building roof at the ENEA research center of Casaccia (Rome, Italy), and shows very good results in the forecasting of One Day- Ahead PV generated power. The results obtained validate this approach as a competitive option to pyranometer-based monitoring in PV installations.
Finite-Key Analysis for Quantum Key Distribution with Discrete-Phase Randomization

Quantum key distribution (QKD) allows two remote parties to share information-theoretic secret keys. Many QKD protocols assume the phase of encoding state can be continuous randomized from 0 to 2π, which, however, may be questionable in the experiment. This is particularly the case in the recently proposed twin-field (TF) QKD, which has received a lot of attention since it can increase the key rate significantly and even beat some theoretical rate-loss limits. As an intuitive solution, one may introduce discrete-phase randomization instead of continuous randomization. However, a security proof for a QKD protocol with discrete-phase randomization in the finite-key region is still missing. Here, we develop a technique based on conjugate measurement and quantum state distinguishment to analyze the security in this case. Our results show that TF-QKD with a reasonable number of discrete random phases, e.g., 8 phases from {0,π/4,π/2,…,7π/4}, can achieve satisfactory performance. On the other hand, we find the finite-size effects become more notable than before, which implies that more pulses should be emit in this case. More importantly, as a the first proof for TF-QKD with discrete-phase randomization in the finite-key region, our method is also applicable in other QKD protocols.
Comparative and Evaluation of Anomaly Recognition by Employing Statistic Techniques on Humanoid Robot

This paper presents the study to differentiate between normal and anomaly conditions detected by humanoid robots using comparative statistics.The study has been conducted in robotic software as a platform to examine the scenario and evaluate between the anomalies and normal behaviour in different conditions.This study employed a machine vision technique to run an image segmentation process and carry out semi-supervised object training within a controlled environment.The robot is trained by differentiating the measurement size of the target object, its location, and the object's visibility within three different frames.The effect is measured by extracting the positive predictive value (PPV) value, mean and standard deviation value from the captured image using statistical techniques in machine vision.The results showed that the mean value decreased by around 50% from the normal scenario when an anomaly occurred.Aside from that, the standard deviation values were more than twofold compared to the common scenario, especially after the object's size grew.In contrast, the deviation value is remarkably small when the target is situated in the middle of adjacent frames, compared to the value when the entire shape is positioned in the frame.Simultaneously, the mean values from the processed image produced a minor difference.
The Meaning of Local Autonomy Seen Through the Results of Local Elections During the Rhee Syngman Government

1949년 지방자치법 제정 이후 줄곧 연기되던 지방선거가 1952년 이승만 대통령의 직선제 개헌안을 위한 정치적 목적하에 별안간 실시되었다. 그런데 지방자치제의 실행은 아래로부터의 민주적인 경험 축적과 제도 확립으로 중앙과 다른 지역 정치의 논리도 확대될 수밖에 없었다. 그와 같은 모습이 제1~2회 지방선거 결과를 통해 어느 정도 나타났다. 제1회 지방선거 결과는 표면적으로 이승만 대통령의 의도에 부합하는 자유당을 비롯한 범여권 계열이 다수를 점했다. 하지만 무소속의 등장과 그 존재감은 단순히 이승만 대통령을 지지하는 측면만이 아니라 그에 반대할 수 있는 세력의 등장으로 이해할 수 있었다. 즉, 지방선거 직후 성립한 시읍면 및 도의회 과반 정도가 대통령 직선제 지지 결의안을 제출하지 않은 점은 이를 잘 보여준다. 또한 이승만 정부로부터 임명된 수많은 지방자치단체장이 지방의회의 불신임에 의해 사퇴하는 상황이 속출한 것도 이를 뒷받침해준다. 이어서 제2회 지방선거에서도 시읍면장을 비롯해 시읍면 및 특별시도의원 선거에서 무소속과 야당은 선전했다. 물론 자유당 당선자의 비율이 제1회보다 높았지만, 그렇다고 야당과 무소속이 참패하지는 않았다. 특히 시읍면장의 경우 무소속의 비율이 자유당보다 높았으며, 특별시 및 도의회 선거에서 서울과 경기는 야당이 앞섰고 경남은 무소속이 앞서는 등 중앙과 다른 지역 정치의 모습을 확인할 수 있다. Local elections, which had been postponed ever since the enactment of the Local Autonomy Act in 1949, were suddenly held in 1952 for the political purpose of President Rhee"s constitutional amendment for a direct election system. However, the practice of local self-government had no choice but to expand the logic of central politics and other local politics through the accumulation of democratic experience and establishment of institutions from the bottom up. Such an aspect was revealed to some extent through the results of the 1st and 2nd local elections. As for the results of the first local elections, the liberal party, which supported President Rhee on the surface, and the pan-ruling party still occupied the majority. However, the emergence of independents and their presence could be read as the emergence of forces that could oppose him, not just the side of supporting President Rhee. In other words, the fact that the city, town, village, and provincial councils that submitted the resolution supporting the direct presidential election system did not have a majority shows this well. This is supported by the fact that many local governors appointed by the Rhee government have resigned due to the non-confidence of the local council. Subsequently, in the second local elections, independents and opposition parties performed well in the elections for the head of city, town, and village, as well as city, town, village, special city and provincial council members. In particular, in the case of the heads of a city, town and village, the ratio of independents was higher than that of the Liberal Party, and in the special city and provincial assembly elections, the opposition parties took the lead in Seoul and Gyeonggi, and the independents took the lead in Gyeongnam, confirming local politics that are different from central politics.
The Recognition of “Goryeodogyeong” from the late Goryeo Dynasty to the early Joseon Dynasty’s intellectuals

Goryeodogyeong is a book recognized for its value as a major historical source of research during the Goryeo dynasty. As such, it can be thought that people have widely read and used Goryeodogyeong since old times. However, the perception of Goryeodogyeong by intellectuals in the late Goryeo dynasty and early Joseon dynasty was very different from now. First of all, it is very rare to directly cite or mention the Goryeodokyeong. In most cases, it stays in re-authentication or simply mentions the name and author. This phenomenon means that even though the dynasty was replaced, the nature of the social culture shared by intellectuals did not change significantly.&#x0D; However, at the same time, there is a strange difference in the attitude toward Goryeodogyeong in the late Goryeo dynasty and the early Joseon dynasty. In the late Goryeo dynasty, Goryeodogyeong was mainly used to find forgotten facts or quote them in poetry. But, in the early Joseon dynasty, Goryeodogyeong was cited as a historical source to explain the history of the old dynasty and critically reviewed in the sentence. In the attitude toward the book called Goryeodogyeong, the continuity and disconnection of intellectual society in the late Goryeo dynasty and the early Joseon dynasty are shown at the same time.&#x0D; On the one hand, this fact suggests that Goryeodogyeong was not widely distributed through engraving or manuscript in the late Goryeo dynasty and early Joseon dynasty. According to the records, the existence of the Goryeo dynasty edition of the Goryeodogyeong, which is different from the current Goryeodogyeong, is confirmed. However, it was not known exactly until now whether there was a Goryeo version of Goryeodokyeong.&#x0D; If the Goryeo version of Goryeodogyeong existed, it is most likely that the engraving was published after correction based on the Song dynasty version introduced from Yuan in the mid-14th century. However, even if it existed, it seems to have disappeared soon after it was not widely distributed. This means that unlike after the 18th century, the demand for Goryeodogyeong was not high among intellectuals at that time.
Robust and blind watermarking algorithm for chaotic system encryption based on discrete cosine transform-singular value decomposition

Through comparison with most frequency-domain digital watermarking approaches, the spread transform dither modulation (STDM) method exhibits a good embedding effect and is capable of meeting the requirements of blind extraction. However, the rotating attack is difficult to counter, and the cropping attack is seriously impacted by location factors. In addition, there exist numerous algorithms concentrate solely on the watermarking process, ignoring the image’s security. In these views, our work proposes a two-dimensional hyperchaotic system, the so-named Chebyshev ICMIC cascade map with the Knuth–Durstenfeld method, aiming to enhance the security of digital watermarking systems. The scrambled pixels improve the anticropping attack effect through breaking the location correlation of watermark information. For the purpose of magnifying resistance to rotation attack impact, the radial harmonic Fourier moments subtraction coefficient matrix distribution expectation is appropriately adapted to carry out the rotation correction. The performed experiments reveal that the suggested improved STDM watermarking algorithm demonstrates better robustness and invisibility, resisting more attacks than the existing methodologies. Finally, the feasibility of the proposed methods is proved based on the simulation results.
Application of Agile Project Management Approaches in the Automotive Industry

Agile Project Management (APM) is a standard approach in the software industry, and because of its success in allowing projects to better meet its requirements, its application has lately been extended to other industries, without prejudice of its underlying principles and advantages. Among APM practices there are: iterative and incremental deploying the product, presence of informal communication and low bureaucracy and use of visual tools. Additionally, sprints allow the exercise of creativity to solve the presented problem and just-in-time planning to better use people’s time. However, adapting practices that were designed for developing a software to other types of products poses many challenges. To shed some light as to how agile practices may be adapted to different contexts, this work conducts a case study of a project in manufacturing that adopted an agile approach. The objective is to analyze how agile practices were applied in this project, from the factory floor to the car dealership. The analyzed project aimed to improve the quality of the after sales services of the company, reducing the percentage of customers problems and complaints related to the service. A semi-structured interview was conducted with the agile coach responsible for the project, which divided the analysis into five areas of study: work and efforts, materiality, agency and creativity, knowledge, and interests and power. Results showed that the highlighted areas are interrelated, since their benefits intertwine while achieving project success. These observed benefits match the application of APM in a software project and were related to practices such as the use of small teams, periodic short meetings, and tools for informal communication. These characteristics made improved project agility and eliminated unnecessary formal documentation and communication. Nevertheless, not all the characteristic tools of APM were used, for example, there was a lack of a project’s backlog and the utilization of an agile board, even though visual monitoring was used during the project’s execution. Future research is proposed to amplify the study, analyzing other types of projects, and develop a framework with the best practices found to implement the APM methodology outside of software projects.
Utilization of Spatial Data on Agricultural Activities Case Study of Tebas District

The dominant potential of agricultural activities is not in line with the dissemination of adequate information on agricultural activities, thus causing agricultural activities in Tebas District to be unknown to the wider community. Information about agricultural activities will be more easily accessed by the community in Tebas District with the existence of a web-based geographic information system where people can get non-spatial information and also spatial information from agricultural activities in Tebas District. The purpose of the study is to determine the use of GIS web applications in monitoring agricultural activities. The research location focused on the Tebas Komplek agricultural area which is designated as a sustainable food agriculture area in Sambas regency which includes Tebas Sungai Village, Pangkalan Kongsi Village, Dungun Perapakan Village, Serumpun Buluh Village and Mekar Sekuntum Village. The research method used in this study used remote sensing and waterfall methods. The remote sensing method is used to build spatial data by using remote sensing imagery, while the waterfall method is used to build a home GIS web for spatial data to be placed. The technique of collecting data on attributes of agricultural activities is carried out by filling out questionnaires, while spatial data collection is carried out by interpreting satellite images and testing the accuracy and tracking of land in the field. The results of the study stated that: 1) A Web Gis application design has been composed which contains the home page, poktan data page, poktan detail page, whole rice field data page, member detail page, login page, poktan data input page, and rice field data input page; 2) The agricultural land system in Serumpun Buluh Village has its own uniqueness compared to Mekar Sekuntum village, Tebas Sungai, Dungun Perapaakan and Pangkalan Kongsi in Tebas Agricultural Area Complex, which uses an overlay system. Serumpun Buluh Village uses a domicile system, which is based on the domicile of farmers and some are based on the location of land owned by farmers; 3) There are differences in the variation in the area of poktan spatial data in each gappoktan located in the Tebas Complex Agricultural Area. The conclusion of the use of the gis web application will make it easier for extension workers and gapoctans to monitor agricultural activities in the Tebas Komplek agricultural area.

Visual Context Embedding and Deadlock Processing for Target-driven Visual Navigation

In this paper, we propose a novel deep neural network-based agent model, (VCENet), for performing target-driven visual navigation tasks. Most recent agent models for visual navigation try to recognize the real-time task context by using only objects and their relationships detected from RGB input images. However, such object-oriented visual context does not contain detailed information about the background scene, which is important for ground navigation. Moreover, it may result in a misrecognized context due to because of errors in of the object and relation detectors. To overcome these problems, the proposed VCENet model represents the real-time task context by using as the appearance and geometric features of the background scene extracted from RGB-D input images well as the object relation features derived through from graph embedding. Many existing models, which learn an action policiesy based upon on reinforcement, learning, do not provide any reward functions to avoid deadlocks ahead during of navigation or any effective deadlock recovery policyy learning mechanisms to escape the deadlocks. To address these problems, the proposed VCENet model provides not only reward functions for deadlock avoidance and recovery, but also a deadlock recovery policy based on imitation learning. Conducting a variety of various experiments in photo-realistic virtual indoor environments provided by the 3D simulator AI2THOR, we made sure of demonstrated the superiority of the proposed VCENet model.
K-Means clustering model to improve competency of diploma program graduates

Completion of studies by students is the result of the process carried out in the learning process in university. The problem that arises related to this condition is that many diploma students are often late in completing their studies or even dropping out of school. Departments at the university do not have a significant measuring tool in predicting student graduation rates based on the competencies mastered. This paper proposes a program model to predict the basic abilities of Information System Diploma Program students to be mapped in the level of ability in an effort to reduce the delay in the learning process. The method used in the program model was a quantitative method with a K-Means Clustering model approach. The results showed that there was a significant increase in the timely graduation rate for Information System Diploma Program. Keywords: Graduates Competency, Diploma Program Student, Information System, K-Means Clustering, Higher Education;
Research-Problem Validity in Primary Research: Precision and Transparency in Characterizing Past Knowledge

Four validity types evaluate the approximate truth of inferences communicated by primary research. However, current validity frameworks ignore the truthfulness of empirical inferences that are central to research-problem statements. Problem statements contrast a review of past research with other knowledge that extends, contradicts, or calls into question specific features of past research. Authors communicate empirical inferences, or quantitative judgments, about the frequency (e.g., “few,” “most”) and variability (e.g., “on the one hand,” “on the other hand”) in their reviews of existing theories, measures, samples, or results. We code a random sample of primary research articles and show that 83% of quantitative judgments in our sample are vague and do not have a transparent origin, making it difficult to assess their validity. We review validity threats of current practices. We propose that documenting the literature search, reporting how the search was coded, and quantifying the search results facilitates more precise judgments and makes their origin transparent. This practice enables research questions that are more closely tied to the existing body of knowledge and allows for more informed evaluations of the contribution of primary research articles, their design choices, and how they advance knowledge. We discuss potential limitations of our proposed framework.
Sweet science: Gluten-free piecrust and Pasteur’s patisserie

When pie is not so easy A couple of months back, the Newscripts gang sliced into the science of piecrust . The secret to a perfectly flaky pastry, our sources said, is to break up gluten with globs of fat and to carefully control water content to prevent formation of too much gluten in the first place. This revelation prompted reader Bradley K. Norwood to write in about challenges he’s had making gluten-free piecrust. “In most gluten-free flours, the gluten replacement is xanthan gum, and I have a homemade mixture that I use as a 1:1 replacement in all my baking, to great success—except in piecrusts,” he writes, along with a request for Newscripts to serve up a helping of gluten-free piecrust science. Water is the reason Norwood’s gluten-free mix succeeds for cakes and muffins but fails when it comes to piecrust, according to Andrea Brown, who is the research
ROLE OF SOCIAL MEDIA IN IMPROVING SPEAKING AND WRITING SKILLS OF ESL LEARNERS AT SECONDARY SCHOOL LEVEL

Social media platforms are popular among young people all around the world. Many institutions have integrated social media as a learning tool to deliver new information and connect students. Social media is one of the most popular kinds of media today, with a wide range of characteristics and attributes. Today the usage of social media is increasing at an alarming rate. Social media is the excellent channel for students to digitally communicate with their peers and teachers. They are able to discuss important topics that are relevant to learning process. The goal of this paper was to find out the role of social media on developing speaking and writing skills of ESL learners and whether social media could motivate or encourage ESL learners enhance their speaking and writing skills. The current study utilized mixed methods including quantitative and qualitative approaches. The instrument, Questionnaires was utilized in data collection. Questionnaires were designed for ESL learners and ESL teachers. The questionnaires’ data were analyzed quantitatively using SPSS. The questionnaires ultimately revealed how much social media affects ESL Learners' speaking and writing skills, develop their talents, boost up their confidence, provide enough chances to practice speaking and writing skills, provide platforms to share their ideas, provide opportunities for discussion with fellows and motivate them. As a result of this study, it is also suggested that social media should be integrated into the pedagogical system in order to dramatically improve ESL Learners' speaking and writing skills. Keywords: speaking skills, writing skills,, social media, ESL learners, ESL teachers.
Raja Ram Mohan Roy's Contributions to Indian Society

One of the most famous Bengali and Indian philosophers of all time, Raja Ram Mohan Roy was a leader of the Renaissance. When superstition, poverty, harassment-neglect-oppression of women, the collapse of Indian education, and other social ills dominated Bengali and India's entire societies in the eighteenth century, Ram Mohan Roy emerged. The social position, rights, and education of women have all deteriorated as a result of the lengthy period of Muslim dominance in India. There were many problems under the East India Company's rule, despite the fact that the colonial rulers established some schooling to support their rule and trade. The caste system was surrounded by an air of untouchability, and the social structure was split into several castes, races, and faiths. The caste system, both high and low, affected women's lives and educational opportunities. This essay aims to demonstrate that Ram Mohan Roy was influential at the time and helped to break down discrimination in the traditional culture and create a modern one. On the other side, he was able to effect a ground-breaking transformation in India's educational system as well as the preservation of women's lives and rights. The study's objective is to describe and evaluate Raja Ram Mohan Roy's contributions to Indian society. The study used an analytical and documentary approach to come at a conclusion.
