рассматривается возможность использования микроэлектромеханических-коммутаторов (МЭМС-коммутаторов) в конструкции планарной антенны Уда-Яги для управления характеристиками диаграмм направленности. Моделирование исследуемой задачи выполнялось на основе использования SPICE-моделей эквивалентных схем МЭМС-коммутатора как в активном (включенном), так и в выключенном (разомкнутом) режиме. Полученные результаты показывают, что использование МЭМС-коммутаторов позволяет обеспечить высокую эффективность работы антенны, при этом удается создать условия для управления характеристиками диаграмм направленности антенны, так как предполагается подключение дополнительных директоров на основе коммутации МЭМС-коммутаторов. Для повышения точности моделирования в выключенном режиме МЭМС-коммутаторы заменялись также эквивалентными схемами. Проведенное исследование подтвердило, что МЭМС-ключи имеют малое сопротивление в активном режиме и высокую изоляцию в выключенном режиме. В процессе моделирования исследовалась планарная антенна Уда-Яги, которая имела тринадцать директоров, из которых двенадцать имели в своей конструкции по два МЭМС-коммутатора для включения и выключения директоров. На основании моделирования было получено, что антенна имеет КНД от 11.8 до 14.1 дБ, при этом КПД во всем рабочем диапазоне частот более 65 %, а благодаря использованию МЭМС-ключей удается обеспечить быстрое подключение дополнительных директоров в планарной антенне Уда-Яги, что повышает направленные свойства антенны

the article considers the possibility of using MEMS switches in the design of a planar Uda-Yagi antenna to control the characteristics of the radiation patterns. The simulation of the problem under study was performed based on the use of SPICE models of equivalent circuits of a MEMS switch in both active and off modes. The results obtained show that the use of MEMS switches makes it possible to ensure high efficiency of the antenna, while it is possible to provide control over the characteristics of the antenna patterns, since additional directors are connected based on switching MEMS keys. To improve the simulation accuracy in the off mode, MEMS switches were also replaced with equivalent circuits. The study has confirmed that MEMS switches have low resistance in the active mode and high isolation in the off mode. During the simulation, the Uda-Yagi planar antenna was studied, which had thirteen directors, of which twelve had two MEMS switches in their design to turn the directors on and off. Based on the simulation, it was obtained that the antenna has an efficiency factor from 11.8 to 14.1 dB, while the efficiency over the entire operating frequency range is more than 65%, and thanks to the use of MEMS switches, it is possible to provide a quick connection of additional directors in the Uda-Yagi planar antenna, which increases the directional antenna properties

Operations, IT, and construction time orientations and the challenges of implementing IOT
Authors: Sturts Dossick Carrie , Snider Madision , Osburn Laura
Published: September 2023

The adoption of Internet of Things has grown significantly in recent years both to address sustainability in campus operations and as part of digital twin systems. This study looks at in-depth cases of large university campus owners and the challenges that this IOT introduces for the maintenance and management of these systems and the data they collect. In this ethnography there are three main time orientations related to facilities management (Facilities), Information Technology (IT), and Capital Projects. First, a university campus is like a small city, with buildings, utilities, and transportation systems - taken together we call this campus infrastructure (buildings 50-100, roads and utilities 20-50 years). Second, IT employees think on 2–3-month scale, working through implementing software and hardware upgrades, configurations and patches, at times needing agile operations to deal with emerging cybersecurity threats. Third, in Capital Projects the design phase can last 9 months, and the construction from 1 - 2 years for a typical project, and this is where IOT technologies are often first introduced into campus. While the capital project teams reflect on the user experience, these teams are often removed from the realities of facilities management and do not understand the time scales or the scope of the work that is required to manage a portfolio of Facilities and IT systems. In this paper, we explore how these time orientations lead to tensions in the owners’ selection of IOT devices and systems, in the integration of new technologies into existing systems, and in the operations of keeping existing systems up and running for the longer time scales of campus infrastructure life spans. Furthermore, this paper presents a paradox: If they speed up, they lose things, if they slow down, they lose other things, and presents ways that owner organizations manage this paradox through temporal boundary spanners who understand the disciplinary requirements, cultures, and frameworks across the organization and helps to mitigate the tensions across these differences.

A major challenge of ocean wave energy converter (WEC) development is to test in the actual ocean. In this article, how a point absorber (PA) WEC was developed and tested during the mid of November 2022 in the ocean is reported. The WEC named Sindhuja-1 was developed from concept, numerical modelling, and laboratory testing. The test site was the VOC Port in Tuticorin, India. The WEC consisted of a buoy, a spar, and a power take-off mechanism. The buoy diameter was 0.75m and the spar length was 10m. The whole design was done at IIT Madras and preliminary tests were done at the wave basin at IIT Madras. The system was transported to the site and a preliminary test was conducted at the harbour area where the water is calm and has a depth of more than 10m. The purpose of the tests was to check any leakage, buoyance, and stability. After that, a hired fishing boat dragged the system over the ocean surface to a location where 20m water dept is there. The distance from the coast was 6km, and wave heights of approximately 0.5-0.8 meters. For the sea trial design, electronic items were insulated, and a cylindrical cover was also put over the electrical components to avoid water splashes or rain. It was found that the system worked vertically, and the system produced a power of about 100W. The paper will explain the challenges faced during the planning and execution of the system.

"The Regeneration of urban brownfields is currently one of the strategies for densification and urban sustainability. However, as an architectural intervention, it is not an easy task and usually leads to two opposing dilemmas; demolition and/or conservation. This difficulty was observed in the regeneration projects of the colonial military brownfields in the city of Tlemcen, where the actors involved adopted different approaches, some of which damaged the existing architectural heritage and its values. The aim of this article is therefore to analyse the transformation processes of the military brownfields studied and to assess their conservation dimension. The latter is considered to be an indicator that makes it possible, on the one hand, to detect the modality of appropriation of the colonial architectural heritage within the projects analysed and, on the other hand, to assess their sustainability from a heritage perspective. This research was therefore based on the following scientific methods: in-situ observation, historical analysis, comparative analysis and semi-structured interviews. The results obtained for the two main study cases showed that the regeneration of the Bedeau barracks has a higher conservative dimension than that of the African hunter’s barracks and can consequently be considered more sustainable in heritage terms.

Microbial fuel cell (MFC) is a green technology that allows recovery of electricity from wastes, thus, it can be applied in environmental conservation, natural resource preservation and bioenergy production. As an attempt to efficiently utilize the increasing amount of bamboo wastes as an input for energy production, this study investigated the electricity generation efficiency of a dual-chamber MFC in sugar conversion into electricity using Pseudomonas aeruginosa PR3 and hydrolysates from the acid pretreatment of Bambusa stenostachya Hack.. MFCs were inoculated with PR3, acclimated with glucose then operated with bamboo hydrolysates containing different total reducing sugars as the anolytes. Total sugar consumption of the MFCs for electricity conversion varied from 76.25 to 96.30% after 48 hours of operation in bamboo hydrolysates. Results from electrochemical analysis showed that MFC with 9.0 g/L sugars from bamboo hydrolysates had better electricity production, with the maximum open-circuit voltage of 620 mV, current density of 1092.08 mA/m2 and power density of 91.16 mW/m2. Microbial communities in these MFCs could effectively recover electricity from up to 9.0 g/L reducing sugars in bamboo hydrolysates, preliminarily illustrating the applicability of the MFC technology in natural resource conservation as a way to produce alternative energy sources from the treatment of bamboo-processing wastes.

FAILURE ANALYSIS OF PRESTRESSED CONCRETE STEEL BAR DURING THE INITIAL DRAWING PROCESS
Authors: Priambodo Toni Agung , Ihlas Apriardi
Published: September 2023

Reinforced concrete is a common structural material used in the modern era. High tension steel provides strength to the concrete structure to reduce internal tensile forces and eliminate cracking. Failure of reinforcing steel causes the reinforced concrete to not have optimal strength and has the potential to cause failure in the main structure. The present paper describes the investigation of the failure case in the prestressed concrete bar (PC bar) during the manufacture of prestressed or pre-tensioned concrete. The failure occurred in the head section area during the initial drawing process. The chemical composition and tensile test showed the raw material complied to the manufacturer's specification. The fractography and microscopic examination of the failure area showed the characteristics of brittle fracture. Stress concentration in the head section and the tempering process of PC bar after quenching process at an inappropriate temperature caused temper embrittlement to be the cause of failure during the initial drawing process.

Published: September 2023

Albania’s pension system faces many challenges and many problems to be addressed. In 2014 the next reform was undertaken in order to facilitate the pension scheme. The literature of the field is not consolidated in the case of Albania, which is mainly due to the short history of poor management and statistics of interest. Foreign literature is a great source of consultation, mainly for reforming the pension system as well as the various schools for social protection. The study aims to shed light on the assumption that the pension system is affected by economic growth. The linear multifactor model is used for the study hypothesis, where it was shown that the pension system affects the country’s economic growth. The main components of the scheme are the income from the scheme, the expenses, and funding from outside the pension scheme. Statistical analysis showed that only the expenditures from the pension scheme indicate the economic growth of the country. Considering the lack of data and time series after these 10 years of study, due to pension scheme problems and the pandemic period, the findings of our study constitute a valuable contribution to the other interested people and researchers in this field, who want to make further investigations and study analysis, financial institutions and governors.

Authors: Weidner Robert , Schmermbeck Katharina , Ott Oliver
Published: September 2023

Um den Menschen bei vielfältigen Tätigkeiten in verschiedenen Arbeitsumgebungen bestmöglich zu unterstützen, muss das Verhalten von Exoskeletten an die wechselnden Anforderungen anpassbar sein. Zur Realisierung wird die Methode eines übergeordneten Reglers nach dem Prinzip der Zustandsautomaten eingeführt. Aufbauend auf Prozesswissen beschreibt der Zustandsautomat den Arbeitsablauf und erlaubt die Betrachtung sowie die Abstimmung der Unterstützung an die Anforderungen einzelner Tätigkeiten.

 

To optimally support humans during diverse activities in different work environments, the behaviour of exoskeletons must be adaptable to changing requirements. To enable this adaptation, the method of a superordinate controller based on the principle of state machines is introduced. Building on process knowledge, the state machine describes the workflow and allows the analysis as well as the tuning of the support with respect to the requirements of individual activities.

Authors: Trung Phạm Quang
Published: September 2023

Chủ nghĩa hậu thuộc địa là một lý thuyết văn hóa - văn học mới ra đời vào thập niên cuối cùng của thế kỷ XX nhưng đã có những ảnh hưởng sâu rộng với tư tưởng của nhân loại, nhất là đối với các nước từng chịu sự thống trị nặng nề về kinh tế, sâu đậm về xã hội của chủ nghĩa thực dân cũ và mới mang tính điển hình như Việt Nam. Đáng tiếc là sự giới thiệu lý thuyết quan trong này ở nước ta hiện nay còn sơ lược, phiến diện, thậm chí lầm lạc, dẫn tới việc vận dụng nó vào thực tế nghiên cứu, sáng tác, phê bình còn nhiều hạn chế. Cùng với việc phân tích, lý giải hiện trạng đó, bài báo đặc biệt tập trung đề xuất một số hướng giải quyết vừa thiết thực trước mắt vừa cơ bản lâu dài, nhằm góp phần đẩy mạnh hoạt động sáng tạo, nghiên cứu văn hóa - văn chương nước nhà lên một trình độ và chất lượng mới, đáp ứng những đòi hỏi ngày một cao của dân tộc và thời đại.

PARALLEL ALGORITHMS OF RANDOM FORESTS FOR CLASSIFYING VERY LARGE DATASETS
Authors: Nghi Do Thanh , Khang Pham Nguyen , Hoa Nguyen Van , Trong Ly Hoang
Published: September 2023

The random forests algorithm proposed by Breiman is an ensemble-based approach with very high accuracy. The learning and classification tasks of a set of decision trees take a lot of time, make it intractable when dealing with very large datasets. There is a need to scale up the random forests algorithm to handle massive datasets. We propose parallel algorithms of random forests to take into account the benefits of Grids computing. These algorithms improve training and classification time compared with the original ones. The experimental results on large datasets including Forest cover type,KDD Cup 1999, Connect-4 from the UCI data repository showed that the training and classification time of parallel algorithms are significantly reduced.
Response planning during question-answering: does deciding what to say involve deciding how to say it?
Authors: Corps Ruth E. , Pickering Martin J.
Published: September 2023

To answer a question, speakers must determine their response and formulate it in words. But do they decide on a response before formulation, or do they formulate different potential answers before selecting one? We addressed this issue in a verbal question-answering experiment. Participants answered questions more quickly when they had one potential answer (e.g., Which tourist attraction in Paris is very tall?) than when they had multiple potential answers (e.g., What is the name of a Shakespeare play?). Participants also answered more quickly when the set of potential answers were on average short rather than long, regardless of whether there was only one or multiple potential answers. Thus, participants were not affected by the linguistic complexity of unselected but plausible answers. These findings suggest that participants select a single answer before formulation.
MODULAR MOBILE TRAINING AND TESTING COMPLEX
Authors: Haponenko H. , Matvieiev L. , Oliinyk O.
Published: September 2023

The materials of the article substantiate the need to create a modular mobile training and testing complex for the purpose of training of experimental-combat units (combat units, groups of scientific and technical support, representatives of manufacturing enterprises of robotic complexes (systems) to conduct tests of experimental or serial samples of robotic complexes (systems) in combat conditions.

The experience of creating proving grounds and their further use allowed to shift the emphasis towards their mobility. The main idea that formed the basis of the modular mobile training and testing complex is the ability to perform tasks as assigned in any part of Ukraine in a completely autonomous mode.

The purpose of the main parts of the complex is presented. It is specified which parts the complex consists of. It was found that they can be: mobile (move on their own car chassis); movable (move on platform means of road, air, rail and water transport); combined. It is allowed to add existing stationary structures (buildings) that meet the requirements of state building regulations to the composition of the elements of the complex.

It has been investigated that the elements of the complex must ensure:

official activity of a permanent staff in the number of at least 30 people (military servicemen, employees) and training of an alternating staff in the number of at least 30 people (those who train), in field conditions regardless of the season and time of day;

conducting tests in field (proving ground) conditions;

residence and daily life of personnel;

storage and maintenance of aerial, ground and water based robotic complexes and systems.

It is assumed that the modular mobile training and testing complex will be used in field conditions, at any time of the year and at any time of the day, and as we emphasized earlier, it should ensure autonomous functioning. It is not intended to be used in areas of hostilities.

If necessary, the complex can be supplemented with other elements.

It is proposed to make such a complex from movable modules. Each module can include: a common compartment (at least 90 % of the total internal volume); technical compartment (cabinet); power supply system; life support system. The development and implementation of other necessary components in mobile modules is allowed.

Further scientific research in this field involves the development of a specification for each element, component, module and their agreement with the certification and codification body of the Ministry of Defense of Ukraine.
