CMSuG: Competitive mechanism-based superpixel generation method for image segmentation
Authors: Cui Qianna , Pan Haiwei , Li Xiaokun , Zhang Kejia , Chen Weipeng 
Published: May 2022

During the last years, object-based image segmentation (OBIA) has seen a considerable increase in the image segmentation. OBIA is generally based on superpixel methods, in which the clustering-based method plays an increasingly important role. Most clustering methods for generating superpixels suffer from inaccurate classification points with inappropriate cluster centers. To solve the problem, we propose a competitive mechanism-based superpixel generation (CMSuG) method, which both accelerates convergence and promotes robustness for noise sensitivity. Then, image segmentation results will be obtained by a region adjacent graph (RAG)-based merging algorithm after constructing an RAG. However, high segmentation accuracy is customarily accompanied by expensive time-consuming costs. To improve computational efficiency, we address a parallel CMSuG algorithm, the time of which is much less than the CMSuG method. In addition, we present a parallel RAG method to decrease the expensive time-consuming cost in serial RAG construction. By leveraging parallel techniques, the running time of the whole image segmentation method decline with the time complexity from O (N) + O (K2) to O (N/K) or O (K2), in which N is the size of an input image and K is the given number of the superpixel. In the experiments, both nature image and remote sensing image segmentation results demonstrate that our CMSuG method outperforms the state-of-the-art superpixel generation methods, and then performs well for image segmentation in turn. Compared with the serial segmentation method, our parallel techniques gain more than four times acceleration in both remote sensing image dataset and nature image dataset.
ARCHITECTURE AND CONSTRUCTION ENGINEERING: BOUNDARIES OF ACCEPTABLE RELATIONSHIP
Authors: Davidich Tetyana 
Published: May 2022

With the emergence of the first organized societies and state formations, construction activity was inextricably linked with the methods of material realization. Even when there were no separate professions of civil engineer and architect, quite complex structures were erected, the construction of arches and vaults allowed to cover huge spaces. Professional skills in the field of construction developed in the process of building associations, so architecture and the beginnings of civil engineering intertwined into a single conglomeration of empirical knowledge passed from teachers to students and consolidated directly in the constructed facilities. The strength of the structure was achieved through the balancing of the structural system and proven in practice methods of load distribution. Construction techniques passed from one era to another, taking into account differences in cultures and worldviews. Each historical culture developed its own style, which reflected the peculiarities of its worldview. The ideological and symbolic content of architecture in those days, of course, dominated the means of functional organization and design solutions. Subsequently, architecture and civil engineering became separate disciplines, which were supplemented by additional ones. Initially, architectural education was provided within art academies, but with the advent of the first educational institutions that graduated civil engineers, it began to be provided there. At the turn of the XIX - XX centuries, the rationalist approach to architecture became increasingly popular. When the final distinction between engineering and architectural training in universities took place, a number of both positive and negative consequences of this phenomenon emerged. Currently, the dominance of construction technology and the widespread introduction of standard architectural solutions have led to the idea that architects can be replaced by developers who need to complete any accelerated courses. To correct the situation at least to some extent, it is necessary to understand that technology exists for the implementation of architectural solutions, and not vice versa.

Published: May 2022

The article has an attempt to reflect the transformation of the process of scientific achievements with reflection of them in real urban planning activities in the formation of the concept of formation and development of territorial communities as group resettlement systems at the local level. An attempt to determine how scientific developments affect the development of urban development theory, practice, norms, laws. Particular attention is paid to territorial planning at the regional level where in the process of administrative-territorial reform there was a new element of the regional system - the territorial community. The scientific and theoretical foundations of the systemic approach of regional planning are considered and substantiated. As a result, six basic conceptual bases of systemicity (system as such, demoecological systems, systems modeling, management of systems, group systems and social aspects of systems are allocated.
Given a city-based understanding of a new object of regional planning - a territorial community, the main advantages and difficulties are allocated in substantiation as such and further development. The methodology for developing the concept of formation of a territorial community as a group system of resettlement of a local level is proposed. A number of shortcomings are defined, which are not taken into account today in the development of project documentation. A number of assumptions are proposed that in the future it is necessary to scientific confirmation in the implementation of the methodology for forming a strategy for the formation and development of group forms of settlement of the local level (territorial communities). It is proved that the group system of settlements (territorial community) as an object of design and planning activity is a subsystem of the overall system of resettlement of Ukraine. The main factors characterizing the information bank of data formation of the local system are highlighted.
ANALYSIS OF THE HISTORICAL SACRED HERITAGE OF SHAANSI PROVINCE
Authors: Ding Yang 
Published: May 2022

The article analyzes the outstanding features of the traditional sacred architecture of Shanxi Province. The largest historical heritage are temples and pagodas. The article focuses on the systematization of monuments within Shaanxi Province, where the sites of nine dynasties are presented, which proves the exclusive place of the province and its capital Xi'an in the history of China. Their example identifies the main semantic features that are the expression of China's national architecture and can be used for modification in modern public buildings for various functional purposes. The turn to national origins in modern architecture has been proclaimed by Chinese government decrees.
The systematization of historical sites by dynastic periods proved the dominance of ruins and burials-tombs in the early periods and their gradual replacement by palaces, temples, city gates.
From the whole set of objects under state protection, those were selected that can be considered as examples of inheritance for modern objects. Thus, the land objects that have preserved their integral form, especially the temple pavilions, were chosen for imitation, taking into account the conservatism and functionality of such buildings as Buddhist pagodas. Land objects included in the conservation register were selected as typical examples of Chinese architecture of a certain period.

Published: May 2022

The article analyzes the conditions for the formation of recreation for children in the structure of an urbanized environment. In the conditions of large cities and metropolitan areas, specialists are faced with the acute issue of creating and shaping a comfortable and safe recreational environment for children. The article explores the main factors that have a decisive influence on the formation of a comfortable environment for organizing children's leisure. The problems of creating recreational areas for children in an urbanized environment are constantly considered by many specialists, including urban planners, psychologists, teachers and others. The article discusses domestic and foreign experience in the creation, operation and development of recreational areas for children in different periods of the development of society, the main tasks of children's leisure and recreation in general.
The modern system of children's recreation, the typology of its objects and elements are analyzed, considering the current standards. In European countries, as well as in Ukraine, the organization of children's recreation is supported by the state and the legislative framework, but the conditions for its formation are milder in comparison with Ukraine. When designing children's recreation in Europe, the state of the urban environment, the unity of space, the overall design and safety issues are necessarily considered, and the child is taught to be careful and competently assess the current situation. In Ukraine, they adhere to the principle – the more sites, the better.
PECULIARITIES OF FORMATION OF RURAL PUBLIC ENVIRONMENT IN THE PROCESS OF ADMINISTRATIVE REFORM

Published: May 2022

The article considers and attempts to draw attention to one of the most important elements of the settlement system, which is the public space of the village, which is represented by multifunctional complexes in accordance with the requirements of administrative reform.
Versatility is becoming more and more an integral part of shaping the community. The concept of "multifunctional" implies the presence of several different functions, which, being independent of each other, can form a common space, be in adjacent rooms and complement each other, forming a kind of social symbiosis of the service system.
Insufficient attention to their formation is one of the reasons for rural-urban migration processes. The article emphasizes some of the main reasons. The mono-profile of individual service facilities does not meet the needs of the population, so the new administrative reform aims to create a complete set of multi-profile system of public service organization on the basis of village centers of the united territorial communities. The historical typological system of formation of rural public environment for the last century in Ukraine is offered.
The selection of individual periods is characterized by a system of criteria according to which the public environment was formed in rural settlements. According to the authors, one of the criteria is the reflection of the public environment in the preserved architectural structures.
The article draws attention to the powerful cultural centuries-old potential of the settlement system of Ukraine and only a small percentage of it we use, losing a number of historical, cultural and ethnic heritage. The new administrative-territorial reform is aimed at involving local self-government not only to preserve, but also to actively develop new concepts and strategies for economic growth of united territorial communities.
On the Effectiveness of Stock Index Futures for Tail Risk Protection
Authors: Zourai Hamadi 
Published: May 2022

This paper examines the effectiveness of using stock index futures contracts as substitutes for fixed-income securities in implementing expected shortfall targeting strategy. We find that the futures-based implementation outperforms its index-and-bill counterpart both in terms of downside protection and risk-adjusted performance at daily rebalancing frequency. This outperformance is driven not only by the transaction cost advantage, but also by the replication imperfections due to futures mispricing providing over the long term a better participation in upward market movements. When less frequent rebalancing intervals are used, the futures-based implementation becomes less effective at protecting the downside risk but still capture better the upside potential of the index.

ABSTRAK Silinder pejal yang menggelinding di atas bidang miring akan mengalami dua gerak sekaligus, yakni gerak rotasi dan translasi. Gerak rotasi terhadap sumbu silinder pejal dan gerak translasi terhadap bidang miring yang dilalui. Dinamika gerak rotasi dan translasi pada bidang miring menjadi kompleks saat silinder pejal bergerak 2 medium yang berbeda kerapatannya. Penelitian ini merupakan eksperimen di laboratorium untuk menentukan profil jarak terhadap waktu dan kecepatan terhadap waktu untuk gerak silinder pada bidang miring dalam air dengan variasi ketinggian air. Pengambilan data dilakukan menggunakan perekaman video dengan variasi ketinggian air pada saat silinder pejal menggelinding pada bidang miring, lalu video tersebut dipindahkan ke laptop untuk di-tracking menggunakan software tracker. Data yang diperoleh dari hasil tracking tersebut kemudian dibuat grafik profil jarak terhadap waktu dan profil kecepatan terhadap waktu. Pada hasil analisis data selain menghasilkan profil jarak terhadap waktu dan kecepatan terhadap waktu juga memperoleh pengaruh variasi ketinggian air pada profil jarak terhadap waktu dan kecepatan terhadap waktu. Semakin tinggi air, maka semakin pendek lintasan yang ditempuh oleh silinder. Perubahan kecepatan silinder cenderung tidak linear bila ketinggian air tidak tinggi karena gaya gesekan dengan lintasan mulai membesar. Silinder bergerak dengan kecepatan hampir konstan pada saat di dalam air. Kata kunci— Silinder pejal, software tracker, bidang miring, air ABSTRACT A solid cylinder that rolls on an inclined plane will experience two motions at once, namely rotational and translational motion. Rotational motion about the axis of a solid cylinder and translational motion about the inclined plane traversed. Rotational and translational motion dynamics on inclined plane become complex as a solid cylinder move inside two different mediums that has different density. This research is an experimental research in the laboratory to determine the profile of distance and velocity versus time of cylinder on an inclined plane in water with variations in water level. Data retrieval is done using video recording with variations in water level when a solid cylinder rolls on an inclined plane, then the video is transferred to a laptop for tracking using tracker software. The data are plotted to obtain graph of distance and velocity profile In the results of data analysis, in addition to producing a profile of distance against time and speed with respect to time, it also obtained the effect of variations in water level on the profile of distance against time and speed with respect to time. Higher the water height, shorter the cylinder path. The changes of cylinder speed tend to be non-linear if the height of water is low. This is due to the drag force with the track start to increase. Cylinder move with the speed almost constant under water. Keywords— Solid cylinder, tracker software, inclined plane, water
