VIRTUAL MODEL OF THE SYSTEM "INDUCTION MOTOR - SOFTSTARTER WITH TWO CONTROLLED PHASES"
Authors: Toropov Anton , Listovshchyk Leonid , Toropova Liliya , Terentiev Oleh
Published: November 2023

One of the most commonly used start methods of induction motors  is starting by gradually increasing the supply voltage. At the same time, softstarters based on thyristors or triacs are used, which are cheaper in comparison with  frequency inverters based on IGBT - transistors. In turn, the disadvantage of this method of starting with significant reduction of the starting torque, so the possibility of using such starters for various executive mechanisms requires careful research. In the presence of a limitation of power source power, especially in wartime conditions, the problem of limitation of starting currents, especially in the case of using starters with two adjustable phases, is actual. To take into account the multiplicity of starting currents for different types of mechanisms, a mathematical model of the system " induction motor - softstarter with two controlled phases" was created. The model differs from the known ones by the possibility of limiting the power of the power supply network, the appearance of the mechanical characteristics of the executive mechanism and the starting moment at voltage ramp start mode. Transient processes in relative units for the possibility of estimating the multiplicity of starting currents to determine the required power of the autonomous power source are presented. To assess the adequacy of the mathematical model, a research stand with measuring of motor winding currents using a current transformer and a microprocessor device with an oscillography function was created. In the work, a comparative analysis of the results of modeling and experimental studies on a physical model is carried out, herewith the discrepancy of the results did not exceed 10%. It was determined that when using a soft-start device with two adjustable phases, even with small voltages, the current multiplicity is quite high and requires the use of a power source of greater power, but less than in the case of direct start. Formulated conclusions based on research results and recommendations for further reduction of starting currents.
СЕРЕДНЬОВІЧНІ МУЗИКАНТИ У ГЕНУЕЗЬКИХ МІСТАХ КРИМУ
Authors: Джанов О. , Кузьмінський І.
Published: November 2023

Завдання дослідження полягає у тому, щоб виявити писемні свідчення про музикантів, які служили в торгових факторіях генуезців у Криму. Ці свідчення повністю сконцентровані у бухгалтерських книгах казначейства (масарії) міста Кафи. Наступне завдання — порівняти отримані факти з аналогічними, що походять із Генуї, тобто метрополії генуезців. Останній етап — це виявлення автентичних іконографічних джерел з Криму та Генуї з зображенням тогочасних музичних інструментів. Наукові підходи базуються на принципах історизму, системності, наукової об’єктивності та діалектичному підході. Було використано сукупність загальнонаукових, міждисциплінарних та спеціальних методів дослідження. У масаріях було виявлено професійних музикантів, які належать до двох категорій службовців: нічні стражники та слуги консула. Перші з них грали на трубах/тюбетах та накрах (невеликих литаврах). Вони служили в Кафі, Солдайї та Чембало. Музиканти консула використовували ширше коло музичних інструментів. Йдеться про тюбетів і трубачів, накраторів, карамелістів (шалмеїстів), замаристів (зурнистів), псалтеристів, лютнистів та органістів. Окрім цього, у книгах масарії було виявлено відомості про військових тюбетів першого татарського хана Хаджі I Ґерая та музикантів Мамая. Порівняльний аналіз назв музичних інструментів Кафи та Генуї дає змогу відзначити їхню майже повну тотожність. Винятком є лише замара (зурна), яка в середньовічних писемних джерелах Генуї не трапляється, що може свідчити про східний вплив. Місцева специфіка Криму проявляється й у поодиноких свідченнях про грецькі та вірменські хори у Кафі. Перспективи подальших студіювань полягають у дослідженні музичної спадщини інших італійських колонізаторів Криму — венеціанців. А згодом варто порівняти отримані результати не лише зі спадщиною Криму, України та Італії, а й інших європейських міст XIII–XV ст. Оригінальність дослідження полягає в представленні абсолютно нової сторінки музичної спадщини середньовічного Криму.

Ключові слова: музикант, музичний інструмент, Кафа, Солдайя, Чембало, Генуя.
РОСІЙСЬКА ПОЛІТИКА В АЗЕРБАЙДЖАНІ В ДРУГІЙ ПОЛОВИНІ XVIII — НА ПОЧАТКУ XIX СТ. (СУЧАСНИЙ ПОГЛЯД)
Authors: Іскендерова М.
Published: November 2023

У статті обґрунтовано і об’єктивно представляється вивчення факторів, що визначили особливу важливість Азербайджану в загарбницькій південнокавказькій політиці Росії в зазначений період. Розглянуті у статті роботи дали змогу об’єктивно оцінити різноманітні методи реалізації експансіоністської політики Росії в Азербайджані, визначити напрями цієї політики та виявити характерні риси у вивченні політичних відносин Азербайджану з Росією в другій половині XVIII — на початку ХІХ ст.

Геополітичне і геостратегічне значення Азербайджану, як і Південного Кавказу, загалом в імперських планах Росії сприяло тому, що політика Росії в цьому регіоні у XVIII — на початку XIX ст. завжди перебувала в центрі уваги дослідників. У статті зроблено спробу історіографічного аналізу праць деяких представників сучасної історіографії, присвячених вивченню російської політики в Азербайджані та її етапів у другій половині XVIII — на початку XIX ст. Розкривається, якою автори бачили суть політики Росії та її інтересів як в Азербайджані, так і на Південному Кавказу загалом. Роботи сучасних дослідників, присвячені цим питанням, дають змогу охарактеризувати гегемоністську політику царизму в регіоні. Аналіз зазначених праць дає можливість простежити відмову від ідеологізованого підходу радянської епохи до досліджуваної проблеми, завдяки чому ці вчені виявили головне — колоніальну сутність політики Росії в Азербайджані в зазначений період.

Важливість скрупульозного історіографічного дослідження політики Росії в Азербайджані випливає з необхідності з’ясування ролі Росії в насильницькому розподілі території Азербайджану та його народу. Новий підхід сучасних дослідників до вивчення азербайджанського вектору південно-кавказької політики Росії дає змогу виявити рівень вивченості історичного коріння багатьох геополітичних процесів сучасності.

З урахуванням розмаїття поглядів на досліджувану тему, спираючись на значний джерельний матеріал, автори статті обстоюють думку, згідно з якою німецькі протестантські колонії успішно вживлювалися в загалом чужорідний соціальний і конфесійний простір в Україні, незважаючи на статус «терпимої» конфесії й завдяки здебільшого лояльному ставленню до суспільного устрою, державних владних інституцій та етноконфесійного оточення. Постановка і «вирішення» «німецького питання» російським урядом на початку Першої світової війни засобом депортації німців з України на північ та схід імперії тлумачаться як псевдобезпекові й політично вмотивовані.

ПРЕЗЕНТАЦІЯ ВІЙСЬКОВИХ СТАРОЖИТНОСТЕЙ НА ВИСТАВКАХ АРХЕОЛОГІЧНИХ З’ЇЗДІВ У РОСІЙСЬКІЙ ІМПЕРІЇ
Authors: Іванюк О. , Мохнатюк І. , Валанцик M.
Published: November 2023

У статті проаналізовано матеріали археологічних з’їздів, які організовувались у Російській імперії в другій половині ХІХ — на початку ХХ ст., зокрема й каталоги виставок. Встановлено, що експозиції формувалися за територіальним принципом і принципом власності. Пам’ятки надавалися від музеїв, наукових товариств, приватних колекціонерів, дослідників. З’ясовано, що помітною складовою експозицій були старожитності, які стосувалися військової історії. Умовно їх можна поділити на кілька категорій: зброя і обладунки, зокрема археологічні знахідки — вістря стріл, списів, залишки мечів епохи міді та бронзи й ранньої залізної доби, предмети озброєння й амуніції різних історичних епох, предмети фалеристики (жетони та медалі), писемні пам’ятки. Характерною ознакою виставок з’їздів була лише часткова атрибуція експонатів, які стосувалися військової історії, що значно ускладнювало їх систематизацію. Найпотужніші експозиції військових старожитностей було представлено на археологічних з’їздах, які відбувалися в Україні. Акценти ставилися на пам’ятках, пов’язаних з історією козацтва, проте найбільшу частину все-таки становили російські військові меморабілії. Рушійною силою у формуванні виставок майже всіх археологічних з’їздів стали українські дослідники й колекціонери.

Ключові слова: археологічний з’їзд, виставка, військові старожитності, озброєння, експозиція, колекція.
УКРАЇНСЬКА МОВА VS ІМПЕРІЯ: ГЛУХИЙ КУТ ІМПЕРСЬКОГО ЕТНОЦИДУ
Authors: Винарчук Т.
Published: November 2023

Автор статті пропонує доповнити дослідження національної політики Російської імперії щодо українців терміном «етноцид». Цей термін, на відміну від поняття «русифікація», віддзеркалює основну імперську мету, яка полягала в знищенні українців як особливої етнокультурної спільноти. Залучення до наукового аналізу концепції модернізації та теорії модерних націй дає змогу розширити розуміння причин, через які Російська імперія заперечувала самобутність української нації, її культури та мови. Нездатність Російської імперії модифікувати російський національний проєкт відповідно до реалій модерної доби, а також політика етноциду української культури та утисків національних прав інших поневолених народів спричинили занепад імперії.

Algorithm for simulating melting polar ice, Earth internal movement and volcano eruption with 3-dimensional inertia tensor
Authors: Matsuki Yoshio , Bidyuk Petro
Published: November 2023

This paper reports the result of an investigation of a hypothesis that the melting polar ice of Earth flowing down to the equatorial region causes volcano eruptions. We assumed a cube inside the spherical body of Earth, formulated a 3-dimensional inertia tensor of the cube, and then simulated the redistribution of the mass that is to be caused by the movement of melted ice on the Earth’s surface. Such mass distribution changes the inertia tensor of the cube. Then, the cube’s rotation inside Earth was simulated by multiplying the Euler angle matrix by the inertia tensor. Then, changes in the energy intensity and the angular momentum of the cube were calculated as coefficients of Hamiltonian equations of motion, which are made of the inertia tensor and sine and cosine curves of the rotation angles. The calculations show that the melted ice increases Earth’s internal energy intensity and angular momentum, possibly increasing volcano eruptions.
Basic algorithm for approximation of the boundary trajectory of short-focus electron beam using the root-polynomial functions of the fourth and fifth order
Authors: Melnyk Igor , Pochynok Alina
Published: November 2023

The new iterative method of approximating the boundary trajectory of a short-focus electron beam propagating in a free drift mode in a low-pressure ionized gas under the condition of compensation of the space charge of electrons is considered and discussed in the article. To solve the given approximation task, the root-polynomial functions of the fourth and fifth order were applied, the main features of which are the ravine character and the presence of one global minimum. As an initial approach to solving the approximation problem, the values of the polynomial coefficients are calculated by solving the interpolation problem. After this, the approximation task is solved iteratively. All necessary polynomial coefficients are calculated multiple times, taking into account the values of the function and its derivative at the reference points. The final values of polynomial coefficients of high-order root-polynomial functions are calculated using the dichotomy method. The article also provides examples of the applying fourth-order and fifth-order root-polynomial functions to approximate sets of numerical data that correspond to the description of ravine functions. The obtained theoretical results are interesting and important for the experts who study the physics of electron beams and design modern industrial electron beam technological equipment.
Renouées asiatiques envahissantes : la restauration de berges par le génie végétal est-elle si bénéfique à la qualité chimique et à la biodiversité du sol ?

Published: November 2023

Les espèces exotiques envahissantes représentent une menace pour la biodiversité à l’échelle mondiale. Parmi les plantes problématiques en France et en Europe, les renouées asiatiques (Reynoutria spp.) posent un véritable défi, leur gestion étant coûteuse et d’efficacité aléatoire. Premièrement, les gestionnaires doivent choisir d’agir ou de ne pas intervenir. Pour décider, il leur faut mieux connaître les conséquences (y compris de la non-intervention) sur le fonctionnement de l’écosystème. Ensuite, ils doivent décider de la technique de gestion. Les techniques issues du génie végétal basées sur la réintroduction d’espèces végétales indigènes compétitives permettent de réduire la dominance de l’espèce exotique envahissante tout en réintroduisant de la diversité végétale. Si de nombreuses opérations de génie écologique ont été menées, leur efficacité pour restaurer le fonctionnement de l’écosystème n’a jamais été évaluée, encore moins sur la diversité et l’activité des organismes du sol. Cet article synthétise les résultats d’une étude portant sur les effets des renouées asiatiques et de la restauration des berges envahies par génie végétal sur la communauté végétale et le sol. Il s’appuie notamment sur une analyse fine de la chimie et de la faune du sol dans deux bassins versants (en Isère et dans le Rhône).
Demonstration to Unify 4 Interactions in Particle Physics with the Zero‐Point Energy and Quantized Spacetime
Authors: Ishiguri Shinichi
Published: November 2023

We propose a new theory beyond the standard model of elementary-particle physics. Employing the concept of a quantized spacetime, our theory demonstrates that the zero-point energy of the vacuum alone is sufficient to create all the fields, including gravity, the static electromagnetic field, and the weak and strong interactions. No serious undetermined parameters are assumed. Furthermore, the relations between the forces at the quantum-mechanics level is made clear. Using these relations, we quantize Einstein’s gravitational equation: Beginning with the zero-point energy of the vacuum, and after quantizing Newtonian gravity equation, we combine the energies of a static electromagnetic field and gravity in a quantum spacetime. Applying these results to the Einstein gravity equation, we substitute the energy density derived from the zero-point energy in addition to redefining differentials in a quantized spacetime. This is how we derive the quantized Einstein gravitational equation without assuming the existence of macroscopic masses. For the weak interaction, by considering plane-wave electron and the zero-point energy, we obtain a wavefunction that represents a β collapse. In this process, from a different point of view than Weinberg-Salam theory, we derive the masses of the W and Z bosons and the neutrino, and we calculate the radius and lifetime of the neutron. For the strong interaction, we previously reported an analytical theory for calculating the mass of a proton by providing a specific linear attractive potential obtained from the zero-point energy, which agrees well with the measurements. In the present study, we further calculate the strong interaction between two nucleons, i.e., the mass of the pi-meson. The resulting calculated quantities agree with the measurements, which verifies our proposed theory.

Published: November 2023

AbstractTo overcome the negative impacts on the environment and other problems associated with fossil fuels have forced many countries to inquire into and change to environmentally friendly alternatives that are renewable to sustain the increasing energy demand. Solar energy is one of the best renewable energy sources with the least negative impacts on the environment. Different countries have formulated solar energy policies to reduce dependence on fossil fuel and increasing domestic energy production by solar energy. According to the 2010 BP Statistical Energy Survey, the world cumulative installed solar energy capacity was 22928.9 MW in 2009, a change of 46.9% compared to 2008. In this study, a PV generation system has been modeled and installed considering uncertain whether based on the hourly wind speed data of New York City (NYC) of year 2014. Regression models has been used to forecast the hourly, weekly, and monthly wind speed of NYC year 2014. Design of experiment (DOE) has been used to determine the optimal panel size (area), the battery capacity size, and other levels of factors.
Retaining Non-EU Immigrants in Rural Areas to Sustain Depopulated Regions: Motives to Remain
Authors: Diogo Elisete Simoes
Published: November 2023

Rural areas, as a system, face multiple challenges. Among these are population decline and attendant economic and social maladies namely demographic issues considering a scarce population. Pull factors for immigrants to go to other countries are known, nevertheless, to comprehend factors for remaining in rural areas after arriving could support a strategic local policy, and for an informed practice. The purpose of the study is to explore motivations shaping immigrants’ intentions to stay in the Alentejo, a depopulated region in Portugal, using a qualitative approach. Research questions are: What motivates immigrants to remain living in depopulated regions in Portugal? Furthermore, what contributions can practitioners and immigrants give for local policy and practice? Eight practitioners and fifteen non-European Union immigrants living in this region were interviewed between 2020 and 2021. Empirical data were analysed, supported by MaxQDA software. Results point out that the intention to remain in rural areas arise from a progressive construction, it is a process that immigrants experience to become motivated to stay long-term. Factors influencing the process include four components: 1. instrumental and material motivations; 2. emotional and social motivations; 3. motivations based on quality of life; and 4. motivations based on political dimensions. Components are conditioned by the availability of : stable and suitable jobs, access to decent and affordable housing, as well as quality of education and health services for their children; additionally to socio-emotional satisfaction, as family reunification, migrants network, integration and real intercultural living in the host community, close relationships to practitioners from social services; and quality of life, such as lower rents, peaceful and secure living conditions, granted a better future for their children as in any another place in Europe, associated finally to the simplified policy enabling one to become a legal citizen. Conclusions highlight implications for policy and practice, suggesting more investment for rural regions to reverse depopulation reality.
Primary Mosaic Neuroendocrine-/Adenocarcinoma of The Prostate: Clinical and Histological Description
Authors: Almási Kálmán , Kránitz Noémi , Kullmann Tamás
Published: November 2023

Background: Mosaic cancers are composed of two or several genetically different cell populations. Mosaicism has been considered to be rare among malignancies, with the exception of the germ cell tumours. Although it has been described that neuroendocrine foci might be present within adenocarcinomas of the prostate, this was meant for advanced stage diseases and the clinical relevance of the histological finding has not been clarified. Patients and methods: We recall a single centre cohort of patients with neuroendocrine cancer of the prostate. We show for the first time histological images of a primary mosaic neuroendocrine/adenocarcinoma of the prostate. Results: Contrarily to the general assumption of a rare disease with poor prognosis, the clinical incidence was found to be 2%, being 50 fold higher than the earlier data. During the follow-up the overall survival of some metastatic patients reached several years. The particularity of patients with favourable outcome was the parallel elevation of PSA and NSE. They received anticancer treatments in an alternating way directed according to the tumour marker that was actually in rise. Histological images of primary mosaic prostate cancers are shown. A model explaining the development of mosaic cancers is presented. Conclusion: Mosaic neuroendocrine-/adenocarcinoma of the prostate is underdiagnosed and its prognosis is underestimated.

Multiple Gateways (GWs) provide network connectivity to Internet of Things (IoT) sensors in a Wide Area Network (WAN). The End Nodes (ENs) can connect to any GW by discovering and acquiring its periodic beacons. This provides GW diversity and hence improves coverage. If the GWs are within vicinity to each other, and they keep sending periodic beacons to be discovered, the result is interference and collisions. In this study, the impact of such intra-network interference is analyzed to determine the maximum number of GWs that can co-exist within a given urban neighborhood. The paper shows the relationship between beacon collisions and the resulting packet loss rates in a given urban environment. The expected collision rates are calculated for the Medium Access Control (MAC) layer. The eventual packet loss rates are calculated with the MAC and Physical (PHY) layers combined. For this purpose, a new co-channel interference model is presented. The model calculates the average Carrier to Interference ratio (C/I) averaged across all the colliding events. It takes into account the partial overlap durations and the relative power of each colliding signal. The model shows that a collision does not always cause a packet loss. Packet losses occur if there is a collision and if the C/I is below a threshold. The performance evaluation is presented using a combination of analytical and simulation methods. The analytical methods provide the theoretical foundation, and have been used to validate the simulation results. Furthermore, the system models are developed from experimental data obtained from measurements with real hardware. Numerical results are provided with a low bit rate Gaussian Frequency Shift Keying (GFSK) modulation at the PHY layer, which is derived from the IEEE 802.15.4 standard specification. This paper provides guidance on selecting the right GFSK modulation parameters for such low bit-rate and narrow bandwidth IoT applications. The analysis and simulation results show that larger beacon intervals help in reducing beacon loss rates, at the cost of larger beacon acquisition latency. On the flip side, the gateway discovery latency reduces with increasing GW density thanks to abundance of beacons.

The feasibility of recovering bioactive antioxidants from Phyllantus emblica leaves using ethanol -water mixture (0 – 100%) and heat-assisted extraction technology (HAE-T) was investigated in this present study. To this effect, the process parameter of operating temperature (OT: 30 -50 oC), solid -to-liquid ratio (S:L: 1:20 - 1:60 g/mL) and extraction time (ET: 45 - 180 min) were investigated on the extract total phenolic content (TPC, mg GAE/g d.w), yield (EY, %) and antioxidant activity (μM AAE/g d.w) by employing the Box-Behnken experimental design (BBD) available in response surface methodology (RSM). Multi-objective process optimization using the desirability function algorithm to determine set of process variables that simultaneously optimize process responses of TPC, EY and AA was also investigated. The recovery process was thereafter modeled with BBD-RSM and multi gene genetic programming (MGGP) algorithm and model reliability assessment via Monte Carlo simulation were conducted for the best performing set of models for predicting TPC, EY and AA values. The HPLC characterization of the recovered extract was carried out to ascertain the phenolic compound constituents of the Phyllantus emblica leaf extract. The 50% ethanol solution was found to be the best for the optimal extraction of antioxidants from Phyllantus emblica leaves. The HAE-T was suitable for recovering bioactive extract from Phyllantus emblica leaves and investigated process parameters have impacts on the recovery process. The process parameters that simultaneously gave the optimum EY of 21.6565%, TPC of 67.116 mg GAE/g and AA of 3.68583 µM AAE/g were OT of 41.61 oC, S:L of 1:60 g/mL and ET of 180 min. The HPLC extract profiling revealed that the bioactive constituents present in the recovered extract were betulinic acid, gallic acid, chlorogenic acid, caffeic acid, ellagic acid, and ferulic acid. Both the developed BBD-RSM and evolved MGGP-based models predicted the observed process response of TPC, EY and AA satisfactorily with BBD-RSM models marginally better in their predictions. The reliability results showed that the BBD-RSM models predicted TPC, EY and AA values with high certainty of 99.985%, 97.569% and 98.661%, respectively.

Textile and clothing is one of the most important industrial sectors, not only due to the significant number of jobs generated, but also because it addresses one of the people’s fundamental needs (clothing). It is, however, a sector with a huge environmental impact, all over the world, and also an important social impact, especially in developing countries. Sustainability in the Textile & Clothing value chain is a known issue, concerning both environmental, and economical-social facets of sustainability. One way to improve sustainability in this sector is by measuring the environmental, economic and social impacts of value chain activities and, ultimately, computing an Environmental and Circular score for each batch of textile and clothing product, and an Economical and Social score for each involved firm, reflected in their products. The consumer will then have the opportunity and responsibility for selecting products with the least negative environmental, economical and social impact. This article presents the results of STVgoDigital project - PPS1, developed in Portugal with the aim of implementing the traceability of textile and clothing products, boosting sustainability in this sector, and preparing the ground for the implementation of the circular economy. More exactly, a blockchain-based textile and clothing value-chain traceability platform is presented, for tracing textile product lots and activities, along the value chain, classifying them with a score, which measures their environmental and social impact. The environmental, economic and social impact scores are based on a set of proposed indicators. The results are assessed through the presentation of a case study of a face towel (home textile) and a case study of a T-shirt (clothing).

The aim of the study was to evaluate the impact of probiotics obtained from agro-industrial substrates fermented with lactic acid bacteria and/or yeasts on the health and changes in the microbiota of the digestive tract of guinea pigs. Eighty male guinea pigs, Kuri breed, 30 days old and 250 g live weight, were randomly selected and divided into four groups of 20 animals each. T0, Control, T1, Lactobacillus acidophilus and L. bulgaricus. T2, Saccharomyces cerevisiae and Kluyveromyces fragilis and T3. L acidophilus, L bulgariccus, S cerevisiae and K. fragilis. T1, T2 and T3 contained molasses-vinasse substrate in their base, the dose administered was 0.75 mL/animal orally. The parameters evaluated were weight gain, occurrence of diarrhea and mortality, blood profile, macroscopic lesions in the digestive tract organs and changes in the microbiota of the stomach, caecum, small and large intestine. Treatments T1, T2 and T3 improved weight gain (p<0.05) and reduced the presence of guinea pigs with diarrhea (p<0.05) and there was no mortality; hematic indices did not vary significantly (p>0.05) between treatments; animals in the control group presented a greater amount (p<0.05) of macroscopic lesions in the digestive tract organs; in the T1, T2 and T3 group there was an improvement in the natural microbiota. It is concluded that the inclusion of microbial additive in young guinea pigs improves intestinal health, consequently, improves weight gain, reduces diarrhea and deaths, and normalizes the natural microbiota of the gastrointestinal tract.

Published: November 2023

The wind flow patterns and pressure distribution around a plus-shaped building are significantly influenced by the dimensions of its re-entrant corners and the overall building height. The present study aims to find the wind effects and study of the pressure distribution with different flow patterns. Plan area of the building is around 300 square meter while the height of the building is 50 meters by keeping the equal length of the re-entrant corners. The research is performed using ANSYS CFX academic version and the results are depicted in various forms such as pressure coefficient (Cpe), stream lines in both vertical as well as in specific surface and pressure contours. The analysis is carried out by varying the wind incident angles, from 0° to 90° at the interval of 15°. The building dimension are scale down to perform the test on length scale of 1:100. Since the considered building model exhibits symmetry along both the axes, present study mostly emphasis on examining re-entrant corners located in the building. This method yields valuable information about how air circulates and how pressure is distributed across a broad spectrum of wind angles. This study provides valuable insights into flow circulation and pressure distribution for a wide range of wind angles.
High Repetition Frequency Solid-State Green Laser with Large Stable Area for Water Jet Guided
Authors: Wang Ji , Zhang Wenwu
Published: November 2023

This paper presents the design and experimental results of a long cavity length Nd: YAG laser with large stable zone for water jet guided laser (WJGL) applications. The design is based on the light transmission matrix and resonator stability conditions, aiming to achieve a large stable zone and a short cut-off thermal focal length (CTFL). A folded concave resonator is researched to enhance the cavity length, and the influence of the tun-able cavity arm length on the oscillating beam in the resonator and in the YAG crystal is theoretically studied. Moreover, the effects of the output mirror curvature and the cavity arm length on the range of the stable area and the cut-off thermal focal length are also investigated. Experimental results show that a stable green laser output is obtained after second harmonic generation (SHG), with a pulse width ranging from 43ns to 143ns within the laser operating frequency range of 5-20kHz. At an operation frequency of 10kHz, the output power is 21.33W, and the instability of the output power within 400 minutes is 0.88%. The laser source achieves a maximum power of 25.7W at 20kHz, and the maximum single pulse energy reaches 2.7mJ at 6kHz. Finally, this is used as the laser source to couple with a water jet with a diameter of 100 microns, achieving a lossless water conductivity transmission over 60mm length with a peak power density of 0.742GW/cm2. These results demonstrate the suitability of the designed laser source for WJGL technology research.
Vehicle Relocation in One-Way Carsharing: A Review
Authors: Eliyan Afnan Fayez , Kerbache Laoucine
Published: November 2023

Carsharing has become increasingly popular in recent years as a sustainable transportation solution, offering individuals access to shared vehicles on a short-term basis. One-way carsharing, in particular, presents unique challenges due to its flexible nature, allowing users to pick up and drop off vehicles at different locations within a designated service area. This flexibility increases the service ridership but comes at the expense of vehicle imbalance among the stations, as some stations may have excess vehicles while other stations have vehicle shortages. Therefore, carsharing companies need to decide on strategies to ensure a balanced distribution of vehicles among the stations. This is essential as unbalanced vehicle distribution can lead to the unavailability of vehicles when needed or, conversely, result in an increased number of unnecessary rebalancing trips, thereby exacerbating traffic congestion and environmental pollution. Such issues can potentially undermine the overall contribution of carsharing to urban sustainability. To this end, this paper reviews the vehicle imbalance problem that arises in this field and the solution algorithms that solve them.
