Published: October 2021

:
Two VSC-MTDC control strategies with different combinations of controllers are proposed
to eliminate transient fluctuations in the DC voltage stability, resulting from a power imbalance
in a VSC-MTDC connected to wind farms. First, an analysis is performed of a topological
model of a VSC converter station and a VSC-MTDC, as well as of a mathematical model of a wind
turbine. Then, the principles and characteristics of DC voltage slope control, constant active power
control, and inner loop current control used in the VSC-MTDC are introduced. Finally, the
PSCAD/EMTDC platform is used to establish an electromagnetic transient model of a wind farm
connected to a parallel three-terminal VSC-HVDC. An analysis is performed for three cases of single-
phase grounding faults on the rectifier and inverter sides of a converter station and of the withdrawal
of the converter station on the rectifier side. Next, the fault response characteristics of VSCMTDC
are compared and analyzed. The simulation results verify the effectiveness of the two control
strategies, both of which enable the system to maintain DC voltage stability and active power
balance in the event of a fault.

Background:
The use of a VSC-MTDC to connect wind power to the grid has attracted considerable
attention in recent years. A suitable VSC-MTDC control method can enable the stable operation
of a power grid.

Objective:
The study aims to eliminate transient fluctuations in the DC voltage stability resulting
from a power imbalance in a VSC-MTDC connected to a wind farm.

Methods:
First, the topological structure and a model of a three-terminal VSC-HVDC system connected
to wind farms are studied. Second, an analysis is performed of the outer loop DC voltage
slope control, constant active power control and inner loop current control of the converter station of
a VSC-MTDC. Two different control strategies are proposed for the parallel three-terminal VSCHVDC
system: the first is DC voltage slope control for the rectifier station and constant active power
control for the inverter station, and the second is DC voltage slope control for the inverter station
and constant active power for the rectifier station. Finally, a parallel three-terminal VSC-HVDC
model is built based on the PSCAD/EMTDC platform and used to verify the accuracy and effectiveness
of the proposed control strategy.

Results:
The results of simulation analysis of the faults on the rectifier and inverter sides of the system
show that both strategies can restore the system to the stable operation. The effectiveness of the
proposed control strategy is thus verified.

Conclusion:
The control strategy proposed in this paper provides a technical reference for designing
a VSC-MTDC system for wind farms.

Published: October 2021

Background
A large number of patient narratives are available on various web services. As for web question and answer services, patient questions often relate to medical needs, and we expect these questions to provide clues for a better understanding of patients’ medical needs.

Objective
This study aimed to extract patients’ needs and classify them into thematic categories. Clarifying patient needs is the first step in solving social issues that patients with cancer encounter.

Methods
For this study, we used patient question texts containing the key phrase “breast cancer,“ available at the Yahoo! Japan question and answer service, Yahoo! Chiebukuro, which contains over 60,000 questions on cancer. First, we converted the question text into a vector representation. Next, the relevance between patient needs and existing cancer needs categories was calculated based on cosine similarity.

Results
The proportion of correct classifications in our proposed method was approximately 70%. Considering the results of classifying questions, we found the variation and the number of needs.

Conclusions
We created 3 corpora to classify the problems of patients with cancer. The proposed method was able to classify the problems considering the question text. Moreover, as an application example, the question text that included the side effect signaling of drugs and the unmet needs of cancer patients could be extracted. Revealing these needs is important to fulfill the medical needs of patients with cancer.

The anti- microbial activity tests of the seed oil, NaOH and ash soaps of the seed oil, of C.albidum were carried out to determine their effectiveness against gram+, gram– bacteria and some fungi strains. The proximate analysis of C.albidum seeds was performed to determine its nutritional benefits to mankind. Agar diffusion tests using Disc diffusion for the pure oils and soaps while the cup plate test method for dilutions was used in the determination of in-vitro activities. Standard methods as described by AOAC, (1990); AOAC, (1984) and Kjeldahl method described by Chang (2003) were used for proximate determinations. The results show the activity of the oil against Klebsiella pneumonia at a concentration as low as 10 mg/ml. The ash-soap of the leaves shows the highest antimicrobial activities because its MIC is the closest to the standard, Streptomycin. It possesses activity against Escherichia coli and Klebsiella pneumonia at a concentration as low as 5mg/ml. The % proximate analysis composition shows Moisture content, Ash content, Crude Fibre, fat/Oil, Protein, Carbohydrates as follows (14.98, 1.90, 2.09, 2.38, 12.14 and 67.65)%. The study concluded by unleashing the great potential of Chrysophyllum albidum seeds as a useful raw material in food, cosmetics and pharmaceutical industries rather than being regarded as waste in the environment

STUDY ON URBAN RESIDUAL SPACE AS SOLUTIONS REVIEW FOR AREA PROBLEMS
Authors: Ayudya Diana , Anggiani Mona 
Published: October 2021

In cities, spaces were intentionally formed, planned, or unintentionally unplanned. Unlike planned spaces, unplanned spaces in urban areas eventually tend to cause problems for the area. These spaces were referred to as residual spaces, which were generally vacant land or open space in various urban spaces. Urban residual space was also commonly found in tertiary activity centers in big cities like Jakarta, one of which was in the trade and service area of the city. Residual space in such areas grew and developed due to dense activity within the area, resulting building density, irregularity in some spatial use and environmental degradation. Due such conditions, several questions are significant to be raised. What are the typology, utilization, and its impacts on the area? Did it only cause a problem, or could it be a solution to problems within the area? This study aimed to examine the typology of residual space based on the shape, location, utilization, and impact of trade and service activities in South Jakarta, Kebayoran Lama area. The proposed approach used was a qualitative study of the residual spaces in predetermined trade and commercial areas. The study results of the physical, spatial, visual, and social conditions of urban residual space were explained descriptively to get a picture of the characteristics of the form, location, utilization, and impact on the area.
Greenway Network: A Participatory Planning Approach for Municipalities of the South Region of Brazil

Published: October 2021

Abstract
Development of greenways represent a planning strategy that seeks to reconcile both nature conservation and human uses. It is crucial for maintaining landscape connectivity in an increasingly anthropized world. Such strategy encompasses complex socio-ecological variables and its success greatly depends on the integration of different types of knowledge and active support from the local communities and stakeholders. This demands participatory planning processes within multidisciplinary platforms that promote a close collaboration between experts and lay people. The goal of this paper is to describe and analyse a participatory planning approach for the early-stage design of a greenway network for municipalities in South Brazil. The majority of southern Brazilian municipalities contain a very high rate of small farms which are under intensive agricultural production, and consequently, harming the natural landscapes. Actions to effectively tackle this problem are scarcely observed. The procedures encompassed by the approach were determined by the context constraints and potentials that make it applicable in the reality at stake. The approach is focusing on the early-stage design of a greenway network plan and comprises two phases with each a multi-stakeholder workshop for the local landscape analysis and the plan co-design by experts and local actors. The application of the approach in a municipality in southern Brazil has enabled local actors to use key concepts of connectivity planning and foster a critical reflection on local issues, and allowed the incorporation of local knowledge into the solution developed by participants. This resulted in a plan tailored to the local reality.
Football Fans’ Views on the Passolig E-Ticket System and the Decrease in Stadium Attendance: The Case of the Turkish Football Super League
Authors: Çakmak Gökhan , Çiftçi Sevda 
Published: October 2021

Abstract
The aim of this research is to investigate the reasons behind the decline in stadium attendance in the Turkish Football Super League since the implementation of the Passolig e-ticket system as well as football fans’ views on this system. The research sample consisted of football fans living in the province of Sakarya. The total number of participants was 500. A questionnaire comprising three parts was used for data collection. The first part of the questionnaire included questions aimed at identifying personal details of the participants; the second part included questions intended to identify their viewpoints on Passolig; the third part asked about their opinions concerning the reasons behind the decline in stadium attendance. The questionnaire contained 38 questions in total, 37 of which were prepared in the form of a five-point Likert scale with an additional open-ended question to identify participants’ opinions of Passolig. Quantitative data obtained through the study were evaluated using the IBM SPSS 25.0 software package, and qualitative analysis methods were employed for coding the questions about participants’ opinions. The study concluded that based on the opinions of the participants, Passolig has not been able to fulfill its intended functions of increasing stadium attendance, minimizing violence, and preventing ticket touting. The participants view Passolig as a means of generating unearned income and understand its implementation as one of the main reasons for the decline in stadium attendance. Besides the implementation of Passolig, high ticket prices, the weak financial situation of fans, and media broadcasts that provoke violence were among the foremost reported reasons for the decline in stadium attendance.
Object-Verb in Early Modern English: Modelling Markedness
Authors: Pérez-Guerra Javier 
Published: October 2021

Abstract
Although Verb-Object (VO) is the basic unmarked constituent order of predicates in Present-Day English, in earlier stages of the language Object-Verb (OV) is the preferred pattern in some syntactic contexts. OV predicates are significantly frequent in Old and Middle English, and are still attested up to 1550, when they “appear to dwindle away” (Moerenhout & van der Wurff 2005: 83). This study looks at OV in Early Modern English (EModE), using a corpus-based perspective and statistical modelling to explore a number of textual, syntactic, and semantic/processing variables which may account for what by that time had already become a marked, though not yet archaic, word-order pattern. The data for the study were retrieved from the Penn-Helsinki Parsed Corpus of Early Modern English (1500–1710) and the Parsed Corpus of Early English Correspondence (c.1410–1695), the largest electronic parsed collections of EModE texts. The findings reveal a preference for OV in speech-related text types, which are less constrained by the rules of grammar, in marked syntactic contexts, and in configurations not subject to the general linearisation principles of end-weight and given-new. Where these principles are complied with, the probability of VO increases.
