This article presents the stability and dynamic response of open loop and closed loop control of Bidirectional buck-boost converter(BBC) using PID and PIDN controllers through transfer function model implemented in MATLAB code. In order to ensure the stability of switch mode power supplies the control loop behaviors need to be characterized. Improvement of stability of BBC using PID/PIDN compensators is demonstrated in both analog and digital domains by plotting bode plots. Step response of BBC using PID /PIDN controllers are plotted that defines the dynamic behavior of the system.PIDN compensator is proposed to maintain a healthy balance between the stability and transient behavior since both are indirectly proportional.

Semantic web data use as a unified data model in various areas, such as Bioinformatics, media data, Wikipedia, social networks, and government open data. Sharing information among people using semantic web helps to understand and manipulation of information. In the semantic web, the Resource Description Framework (RDF) denotes the linked data. The logical data is represented as RDF model to manage the unformatted data and it provides an ability to machine interpretability of data. The major problem on the web is to handle the large volume of the data that also has other challenges like query processing and optimization over widely distributed RDF data. In this research, the Teacher Learning based Optimization (TLBO) algorithm is proposed for the query optimization to reduce query cost, and optimize the computation time of the query. The TLBO technique select the suitable location and size of the population based on the data that effectively provide the solution for the distributed data i.e.., triple pattern of semantic web. The experimental result showed that the TLBO in query optimization performed well in the manner of query computation time compared to existing methods like MARVEL. Additionally, the results showed that the proposed TLBO model achieved nearly 4.93 seconds for executing the multiple queries in LUBM dataset.

In today's world, refrigeration systems have shown significant applications in both industrial and domestic sectors. The majority of the domestic sector refrigerators work on vapour compression system. The leakages of widely used hydro fluorocarbon refrigerants from refrigerator show a severe impact on the environment like global warming, ozone depletion, etc. In order to overcome these problems, eco-friendly refrigerants like hydrocarbons, their Mixtures, etc. are to be used in place of HFCs. in this experiment, the HC Mixture of both R600a and R290 is used. HC refrigerant has negligible GWP (0-3) and zero ODP. In the domestic refrigerator, the power requirement to compressor increases with an increase in compression load. The Diffuser reduces the mechanical work required for the compressor by providing extra work to the refrigerant and nozzle enhances the Refrigeration effect by providing an increase in velocity to the refrigerant. Experiments are conducted to analyse the performance.

The problem of global warming is a threat to humankind. A slow, steady and gradual increase in the average temperature on the planet is a systematic event directly related to the negative effects of climate change. This phenomenon contributes to the rise of the world ocean level, and, as a result, leads to flooding of large territories. The world community is concerned about the need for concerted action within the UN to develop common standards and principles to counter the negative effects of global warming and climate change issues have become the subject of legal regulation on international and regional levels. Climate change under discussion has been an important issue for more than a decade. However, at present, humanity is facing a real threat to its further existence, as the increase in the average planetary temperature threatens not only natural but also economic, social and political crises and disasters. In this paper, the authors analyze various effects of global processes, in which humans take part, on the prospects and directions of the development of civilization. The focus is on one of the most important problems – the negative impact of humans on the environment – the current situation and potential threats. The authors attempted to address the specific consequences of climate change from the standpoint of the existing international legal regulation, from the 1992 Framework Convention to the 2016 Paris Agreement, while highlighting the economic and political dilemmas faced by the international community, as well as various scenarios of development for different regions of the world. Naturally, the positions of the two antagonistic world powers, the Russian Federation and the United States of America, are discussed, as well as the conflict of interests of the international community as a whole and individual states. The authors also discuss a rather sensitive matter of protection of individual rights of people, mentioning certain achievements in this area due to the functioning of international human rights mechanisms, both of quasi-judicial and judicial nature. As a conclusion for the commentary, the authors formulated the consequences to which this trend can lead, considering both the economic, social and political aspects.

The web is one of the largest textual data repositories in the world. There is voluminous data in the digital world. To search for online hotels based on specific requirements of the user is not a very easy job. Ratings and reviews available on different travel websites help to some extent but gives generalized recommendations. A recommender system (RS) which uses reviews is known as content-based and is preferred, to produce a recommendation. Proposed RS maps all requirements of a traveler to features of a hotel and produces person specific recommendation. Phrase-based Recommender System is proposed to reduce efforts and time as compared with a traditional generalized recommender system. The proposed approach makes use of hotel reviews downloaded from TripAdvisor site. The technique initiates with phrase-based feature extraction followed by iterative clustering and ends with feature mapping and exports more relevant recommendations. Betterment of a technique is proved in terms of relevance, accuracy, scalability, and consistency by comparing precision and entropy refinement and corpus size with existing technique.

The cooperation for big data applications through the cognitive radio innovation requires wideband spectrum sensing. Conversely, it is expensive to employ long haul wideband detecting and is particularly troublesome within the sight of vulnerability. For example, more noise, obstruction, anomalies, as well as channel blurring. In this article, we project the planning of successive compacted range detecting which together endeavors compressive sensing (CS) and consecutive occasional identification procedures to accomplish increasingly exact and convenient wideband detecting. Rather than summoning CS to recreate the signal in every period, our projected plan executes in reverse assembled packed information consecutive likelihood proportion test (in reverse GCD-SPRT) utilizing compacted information tests in successive identification, while CS recuperation is just sought after when required. This technique altogether diminishes the compressed sensing recuperation overhead, and on different exploits successive location to increase the detecting excellence. Moreover, we project an inside and out detecting plan to quicken detecting basic leadership when an adjustment in channel position is suspicious, (b) a square scanty CS remaking calculation to abuse the square sparsityfeatures of wide range, and (c) a lot of plans to meld results from the recuperated range signs to additionally improve the general detecting exactness. Broad execution assessment results demonstrate that the projected plans can altogether outflank peer conspires below adequately low SNR properties.

Manusia dengan berbagai aspek yang mempengaruhinya seperti tingkah laku, batas sosial, budaya dan kecenderungan menguasai wilayah atau territorial mempunyai peranan yang besar sekali dalam pembentukan dan perkembangan kota dengan pendekatan perancangan kota. Adanya kecenderungan pengelompokan oleh manusia dalam suatu areal perkotaaan berdasarkan pada pemahaman terhadap keserba samaan, penjabaran kualitas lingkungan, gaya hidup, sistim simbol dan pertahanan melawan kepadatan dan ketegangan permasalahan penduduk. Terkait dengan hal ini, pada perkembangan kota Samarinda di Kalimantan Timur ada salah satu fenomena yang timbul dengan lingkungan terbangun atau built environment yang mempunyai properti yang menurut Rapoport(1984) akan diambil alih oleh komunitas bila tempat yang ada bisa memberikan penilaian tinggi terhadap karakteristik lingkungannya atau akan ditinggalkannya bila tempat tersebut mempunyai anggapan negatif. Yang selanjutnya dapat dinyatakan sebagai pull factors dan push factors sebagai istilah yang biasa dipakai dalam Perancangan kota,Fenomena yang ada di kota Samarinda saat ini adalah dengan masih maraknyaÂ  pedagang kaki lima (pkl)Â  yang berjualan di lokasi-lokasi terlarang di Samarinda. Adapun salah satunyaÂ  yang menyolok adalah pedagang buah-buahan yang berada di sepanjang jl. Slamet Riyadi dan jalan sekitarnya. Pada perkembangannya untuk mengatasi para pedagang buah tersebut ternyata pemkot Samarinda mempunyai berbagai kendala dan masalah yang ada. Hal ini ada kaitannya dengan masalah kecenderungan para pedagang buah yang bisa dikatakan sebagai suatu komunitas tersendiri yang mampuÂ  melakukan tindakan pull factors dan push factors.
PERSEPSI MASYARAKAT TERHADAP IMPLEMENTASI KEBIJAKAN ZONASI SEKOLAH DALAM PENERIMAAN PESERTA DIDIK BARU (PPDB) TINGKAT SMA TAHUN AJARAN 2017/2018 DI KOTA SAMARINDA

Published: August 2019

UU Nomor 20 Tahun 2003 tentang Sisdiknas menyebutkan bahwa setiap warga negara mempunyai hak yang sama untuk memperoleh pendidikan yang bermutu. Namun fenomena yang terjadi saat ini terdapat kesenjangan yang cukup kasat mata karena maraknya sekolah negeri berlabel unggul yang digagas pemerintah di hampir setiap daerah yang tentu membuka jurang kesenjangan yang begitu lebar dengan sekolah lain yang berstatus tidak unggul. Sekolah unggulan terkesan hanya bisa dinikmati anak-anak dengan kemampuan akademik serta finansial tertentu.Â  Orang tua murid pun berlomba untuk menyekolahkan anaknya di sekolah unggulan.Â  Sehingga dampaknya ada sekolah yang banyak muridnya dan ada sekolah yang kekurangan siswa.Â  Tentu saja ketidakmerataan ini akan menimbulkan ekses yang tidak baik pada dunia pendidikan nasional.Â Menyikapi hal tersebut, pemerintah melalui Kementerian Pendidikan dan Kebudayaan menetapkan Permendikbud Nomor 17 Tahun 2017 tentang Penerimaan Peserta Didik Baru pada Taman Kanak Kanak, Sekolah Dasar, Sekolah Menengah Pertama, Sekolah Menengah Atas, Sekolah Menengah Kejuruan atau bentuk Lain Yang Sederajat.Â  Dalam Permendikbud tersebut ditetapkan pemberlakuan sistem zonasi dalam penerimaan peserta didik baru.Â  Dalam sistem zonasi diatur bahwa sekolah yang diselenggarakan oleh pemerintah daerah wajib menerima calon peserta didik yang berdomisili pada radius zona terdekat dari sekolah, paling sedikit sebesar 90 persen dari total jumlah keseluruhan peserta didik yang diterima.Penelitian ini bertujuan untuk menggambarkan persepsi masyarakat terhadap pelaksanaan kebijakan zonasi sekolah dalam PPDB tingkat SMA Tahun Ajaran 2017/2018Â  di Kota Samarinda. Jenis penelitian ini menggunakan penelitian kualitatif melalui metode penjelasan (explanatory). Teknik pengumpulan data dilakukan melalui wawancara dengan orang tua murid, perwakilan sekolah dan dinas terkait juga didukung oleh studi literatur yang berhubungan dengan kebijakan zonasi sekolah. Hasil penelitian menunjukkan bahwa pelaksanaan kebijakan zonasi sekolah menimbulkan gejolak di masyarakat. Waktu sosialisasi yang terbatas, kurangnya pemahaman terhadap mekanisme PPDB dengan sistem zonasi dan juga standar pendidikan yang masih belum merata merupakan beberapa kendala dalam pelaksanaannya di lapangan.
Flâneur or Choraster: A Review of the Travel Narrator In the Formation of the Tourist Experience
Authors: Wearing Stephen , Schweinsberg Stephen , Johnson Patricia
Published: August 2019

Media representations of destinations play a powerful role in tourism appeal. The narrator assumes a role infused with knowledge and power, employing discourse to describe and interpret places and people to entice armchair audiences to not only travel vicariously alongside them, but
to follow in their footsteps. This review article uses the English actor and writer Michael Palin to examine this phenomenon through the lens of the flâneur and choraster. Palin's travels have traditionally been viewed based on their ability to create space from the perspective of a
representational voice of authority. In the present article, we wish to ask whether the power of the travel narrator for tourism is perhaps better expressed in their ability to develop a counter (or chora discourse), one where we are able to see space as locally contested. Palin's narrator
expresses appreciation of his reliance on the people (chora) that inhabit the spaces he visits. His narrations of travel evidence how the flâneur perspective is influenced (and/or disrupted) by a chora in two ways—that which influences the perspective before travel and directs
the gaze, and those that occupy and inscribe meaning on the spaces that are traveled to, that influences and/or forms experience.

Airbnb has become a strong competitor for hotels when it comes to accommodation choices. However, few studies have analyzed the service quality provided by Airbnb. In order to approach this gap and to support the industry to maintain competitiveness, this study identified related dimensions
measuring the service quality based on a qualitative design, conducting a content analysis of Airbnbrelated reviews. The following six dimensions are identified and discussed: Accuracy, Cleanliness, Rooms and Facilities, Location, Personalized Service, and Value. Findings indicate that competitive
advantage can be maintained by improving target group-related service quality, the accuracy and relevance of information provided, flexible check-in and check-out slots and services, as well as the organization of tours and events for guests.
Dynamic Performance Assessment System For Green Tourism Supply Chain
Authors: Huang Hai-Yu , Wei Hai-Xiang , Wei Min
Published: August 2019

As a form of sustainable tourism development, green tourism is a means of environmental protection and a trend of tourism development. Evolutionary game theory is applied to examine the generation of green behaviors by tourism enterprises during the development of a green tourism supply
chain. Model deduction and simulation data analysis show that most tourism enterprises do have an incentive towards green development and the formation of the green tourism supply chain is a dynamic evolution process. To better understand the gaps in the process that all the stakeholders need
to fill, the approach of balanced scorecard (BSC) combined with expert interviews is applied to design a periodical performance assessment system for evaluating the performance of the green tourism supply chain. Evaluation results will help to facilitate all participants to implement green
practices for smooth transformation of a traditional supply chain into a green one.
The Influences of Revenue Diversification and Incoming Tourists on the Performance of Star-Rated Hotels in China
Authors: Lei Chun Kwok (Henry)
Published: August 2019

Human capital and a transformed data set are combined into a stochastic frontier analysis to estimate the technical efficiency of star-rated hotels in 30 provinces and municipalities of China for the period of 2011–2015. The influences of revenue diversification across room, food
& beverage, and other services and incoming tourists on technical efficiency, labor, and capital productivities are addressed. Hotels in Zhejiang, Shanghai and Tianjin are found to be the most efficient. For the efficiency and productivities determinants, per capita GDP of the hosting
province is the primary determinant, hotel ranking and diversification in revenue sources contribute to efficiency and partial productivities, while tourists from different origins bring about diversified impacts. Hotels located in regions with more Taiwan tourists are more efficient with
higher capital productivity. Tourists from Hong Kong, Macau, and foreign countries have brought about both positive and negative linkages to efficiency and partial productivities. In general, hotels can reallocate their resources to diversify their services for better efficiency and productivities.
In contrast, expanding external markets cannot guarantee higher efficiency and better productivities. Hotel management should be careful in formulating their marketing strategies.
