Carved Arabesques in Malay Traditional Houses: Skill, Tradition and Preservation of Identity
Authors: Zumahiran Kamaruddin
Published: December 2024

This study aims to explore the placement and fabrication of the wood carvings within the old Kelantan and Terengganu timber houses. The main objective of this study was to examine the placement of wood carvings in the houses with emphasis on its fabrication as house components. Non-interactive and interactive methods of data collection were employed as research tactics. The non-interactive method involved archival review of 25 sets of measured drawings of the Kelantan and Terengganu timber houses from the Centre for Study of Built Environment in the Malay World at the Universiti Teknologi Malaysia. The interactive method involved semi-structured interviews with five woodcarvers to obtain their verification on the findings from the analytical review which served as the primary data. The study found that architectural components of the houses especially perforated ventilation panels of walls, doors and windows were fabricated in different composition of carvings with intricate arabesque design. Regularity in the placement of these components give spatial identity to the principal spaces such as â€˜rumah ibuâ€™ (core house), â€˜serambiâ€™ (verandah) and main bedrooms. Fabrication of the carvings as housecomponents was in parallel with their structural layouts and functions. This architectural inclination addresses the relationship of creativity, skill and intrinsic knowledge of the Malay craftsmen in keeping the tradition upon the exquisite forms of the houses in general and the carved arabesques in particular. The regional identity of the carvings has been practically and consistently sustained through ages, which suggests preservation of architectural identity within the traditional living environment.

Published: December 2024

Kanser gibi yaşamı tehdit eden hastalıklarda, tanı aşamasında, tedavi sürecinde sık karşılaşılan yan etkiler, hastalık sürecindeki değişimler ve gerçekleştirilen majör cerrahi müdahaleler, hastaların uyum sürecinde çeşitli zorluklar yaşamalarına neden olabilmekte ve bu durum ruhsal sorunların ortaya çıkışını tetikleyebilmektedir. Bu bağlamda, ruhsal sorunların önlenmesi amacıyla yapılan çalışmalarda, bireylerin hastalığa uyum düzeylerini ve baş etme stratejilerini daha iyi anlamak için sahip oldukları kişilik özelliklerinin belirlenmesi önem taşımaktadır. Bu araştırmada hastaların tanı ve tedavi aşamasında önemli katkısı olacağı düşünüldüğünden, betimsel araştırma yöntemi kullanılarak meme kanserli hastaların kişilik özelliklerinin belirlenmesi amaçlanmıştır. Araştırmanın örneklemini olasılıksız rastlantısal örnekleme yöntemi ile 86 meme kanserli hasta oluşturmaktadır. Veri toplama araçları olarak Kişisel Bilgi Formu ve MMPI Çok Yönlü Kişilik Envanteri (Minnesota Multiphasic Personality Inventory - MMPI) kullanılmıştır. Araştırmaya katılan hastalarda L (yalan), F (sıklık-nadirlik), Pd (Psikopatik Sapma) ve Ma (Hipomani) alt ölçek ortalama puanlarının, katılımcıların yaşlarına, algılanan aile gelir durumuna ve eski meme probleminin varlığına göre anlamlı düzeyde farklılaştığı görülmektedir (p<0.05). Daha önce meme problemi yaşamayan hastaların yaşayan hastalara göre ölçek maddelerini daha fazla gelişigüzel şekilde yanıtladığı görülmüştür. Daha önce meme problemi yaşamayan hastaların yaşayan hastalara göre daha fazla toplumsal kurallara ve değerlere uymada güçlük yaşadığı bulunmuştur. Meme kanseri tanısı alan hastalarda, bireye özgü bir olgu olan “kişilik yapısının” belirlenmesinin, başta hemşireler olmak üzere, bütüncül bakım sunan tüm sağlık profesyonellerine hastaların uyum süreçlerini destekleyici ve ruhsal açıdan güçlenmelerine katkı sağlayacak müdahalelerin planlanmasında önemli bir rehberlik sağlayacağı düşünülmektedir.

Authors: Kağıtcı Yıldız Burçin , Uysal Gürdal Hacer Hande
Published: December 2024

Abstract: The present study aims to explore the insights of Turkish early-career researchers into the use of self-mention and code-meshing strategies to construct an authorial identity. The data were obtained from six early-career researchers in the field of social sciences who have publication experience in both Turkish and English, and collected through a demographic information questionnaire and in-depth individual and group interviews. The qualitative analysis of the data revealed that Turkish early-career researchers tend to have a distant approach towards highlighting their authorial identity in academic texts, bringing forward the issues of academic culture, intelligibility and power dynamics, although some milder views are present suggesting that such practices help establishing a strong existence in academia. Some suggestions are made towards creating a more inclusive and flexible writing education that fosters voice development of writers.

Keywords: academic writing, authorial identity, early-career researchers, self-mention, code-meshing

Published: December 2024

Capital structure is the mixture of debt and equity financing that a company uses to funds its operational activities and investment activities. This financing influences a firm’s risk profile and capacity to respond to the market competition and market pressures, directly affecting its financial health and competitive standing. In this paper, we examine the impact of capital structure on firm performance and market competitiveness, specifically within Pakistan textile sector. The research explains how different financial metrics influence market concentration, measured by the Herfindahl-hirechman index (HHI). Empirical results reveal that DAR and ROA have a positive impact, statistically significant effect on market competitiveness, that demonstrating the increased leverage and asset efficiency can enhance a firm’s competitiveness. Generalization of the results may be limited which mean that the future research is required to study the phenomenon in multiple industries and regions, other than the core main variables, the use of other variables could enhance a better insight about the market competitiveness.

Recognition of Animal Pain
Authors: Olivier Abraham
Published: December 2024

Animal pain and suffering is mostly caused by humans, particularly by the human use of domestic animals. This calls for the recognition of animal pain and suffering. My focus is on pain-related suffering. I argue for recognition in the phenomenological sense of giving adequate regard to pain experience in animals and their capacity to express it in their own species-specific terms, in a way that will motivate us to prevent it. My advocacy for the recognition of pain in animals consequently includes a consideration of moral and political action to avert their suffering.

Published: December 2024

The purpose of this study was to test and analyze how Indonesia's foreign exchange reserves were affected by imports, exports, inflation, and foreign debt. Regarding the relationship between Indonesia's foreign exchange reserves and imports, exports, inflation, and foreign debt for the 2019–2023 timeframe, there is a gap between theory and empirical data, which makes this study noteworthy. In order to regulate it and preserve economic stability, it is crucial to constantly track the movement of foreign exchange reserves. Data for the study were taken from official publications of Bank Indonesia (BI), the Central Statistics Agency (BPS), and the Indonesian Economic and Financial Statistics (SEKI). Monthly data was gathered for the study between 2019 and 2023. Using time series data for the 2019–2023 period, including monthly data and up to 60 series data, the sampling was carried out in Indonesia. using conventional hypothesis testing (t, f, and determination tests) and assumption checking (multicollinearity, normality, and heterokedasitas tests) to estimate multiple linear regression. While imports, exports, inflation, and foreign debt are independent factors, foreign exchange reserves are the dependent variable. The results of the study show that the dependent variable is influenced by two independent variables. Foreign exchange reserves are positively impacted by exports, but negatively by inflation. Furthermore, imports and foreign debt have no effect on foreign exchange reserves, making them independent variables that do not affect the dependent variable.

Декарбонизация, как системная проблема для Казахстана, становится всё более актуальной. Республика занимает 64-е место в рейтинге стран с худшим индексом загрязнения воздуха. Доля выбросов вредных веществ от промышленных предприятий превышает 85%. В 2020 году министерство экологии привело данные, что суммарно каждый год в воздух выбрасывается более 2,5 млн. тонн отходов. Этот показатель ежегодно увеличивается на 100 тыс. тонн.
Одним из основных источников загрязнения атмосферы являются энергогенерирующие предприятия. В Казахстане ~ 75% электроэнергии вырабатывается из угля и нефтепродуктов. Последствия использования угля в качестве энергоносителя являются наиболее тяжёлыми. При его сжигании выделяются азот- и серосодержащие оксиды, летучие органические соединения, зола, пыль и СО2, а также металлы, которые могут рассеиваться на больших площадях.
Технология декарбонизации как процесса может быть сильно осложнена присутствием в дымовых газах вышеперечисленных компонентов. Следовательно, необходима предварительная очистка, поскольку ни один сорбент или мембрана для извлечения диоксида углерода не выдержит длительного «давления» со стороны пылевых частиц и отравляющих примесей.
Вместе с тем, установка систем газоочистки, в том числе с использованием каталитических модулей в дымоотводы (трубы) промышленных предприятий, сопряжена с определёнными трудностями, связанными с изменением прочностных характеристик дымоотводов и возрастания газодинамического сопротивления для отходящих газов внутри них.
Данная работа посвящена решению именно этой проблемы путём использования универсального узла крепежа для установки модулей каталитической нейтрализации в дымоотводы промышленных предприятий при предварительной очистке дымовых газов в технологии декарбонизации. В работе описывается конструкция универсального узла крепежа и приводится его схема.

Authors: Bindelli Francesca
Published: December 2024

This paper presents a reconstruction study of the ‘Tappatino’, a rustic farmhouse in the Archaeological Park of the Roman city of Suasa (Castelleone di Suasa, AN). As a multi-stratified site, a wide range of data from both archive sources and archaeological research has been analysed as a starting point for this study. In addition, topographic surveys and the stratigraphic analysis of the masonry were conducted. Finally, the paper describes the application of the Extended Matrix Framework (EMF) to the 3D reconstruction of this area and suggests a reconstructive proposal for the Roman imperial age.
Documenting a hilltop settlement: methodologies and preliminary results of the joint Albano-Italian project at Çuka e Ajtoit (Albania).
Authors: Bogdani Julian
Published: December 2024

The archaeological site of Çuka e Ajtoit (lit. “mount of the eagle”) is located at the southern fringe of the Albanian territory, a few kilometres from the Greek border, on the top of a conical hill with very steep slopes. Its sharp profile dominates the lowland area extending from Butrint in the north, a World Heritage site by UNESCO, to the valley of Kalamas, ancient Thyamis in the south. The area, known as Cestrine or Cammania during Antiquity was located in a highly significant geographical position, along the channel of Corfu, opposite to the city of Corcyra, along the maritime route connecting Balkan Greece to Sicily and Magna Graecia.
DÖNGÜSEL ANLAM TANIMLAMASININ AŞILMASI: ANNA WİERZBİCKA VE SEMANTİK YAKLAŞIMI
Authors: Güngör Selim
Published: December 2024

Semantik araştırmaların en temel sorusu anlamın ne olduğudur. Sözcük anlamının tanımlanması sırasında karşılaşılan en büyük sorunsallardan biri ise döngüsellik veya dögüsel anlam tanımlamalarıdır. Çünkü döngüsellik herhangi bir anlamın, eş-yakın anlamlılık içeren başka bir sözcük aracılığıyla tanımlanmasıdır. Buna göre, döngüsel anlam tanımlamaları aslında bir yer değiştirme işlemidir; bu da sözcük anlamlarının tanımlanmasında bir kısırdöngüye neden olur. Dolayısıyla döngüsel anlam tanımlamaları anlama dair hiçbir açıklama içermemekle kalmaz; aynı zamanda eş-yakın anlamlı sözcükler arasındaki farka ilişkin bilgi sunmakta da yetersiz kalır. Sözlükçülük açısından ise döngüsellik, yapılacak ek açıklamalarla bir tanımlama yöntemi sayılır. Üstelik, sözlükçülük alanında döngüsellikten kaçınmanın mümkün olmadığı da belirtilir. Yine de yerine ikâme yoluyla bir anlamın tanımlanması, semantikçilerce eleştirilmektedir. Anlam sorununa bağlı olarak döngüsellik çıkmazlarına eleştiri getiren birkaç saygın semantikçi sayılabilir: Wierzbicka, Apresyan. Wierzbicka için döngüsel anlam tanımlamaları büyük bir anlam sorunu barındırır. Döngüsellik içeren tanımlarda, tanımlamaların bir aldatmacadan ibaret olduğunu söyleyen Wierzbicka, kısırdöngüden kurtulmanın yolunu semantik ilkler temelinde yapılacak bir yorumlamada bulur. Anlamsal olarak daha alt bir ayrıştırmaya indirgenemeyen ve tanımlanamayan semantik ilkler temelinde yapılacak bir yorumlama-açımlama, anlamsal olarak en basit düzeydeki sınırlı sayılı sözvarlığı birimleri ile gerçekleştirilir. Gerçekleştirilen açımlama işlemi, Doğal Semantik Üstdil terimiyle adlandırılır. Wierzbicka’nın karmaşık anlamları daha basit anlama indirgeyici yaklaşımı, döngüsellikten kaçınmanın olası yollarını göstermekte oldukça başarılıdır. Bu doğrultuda makale, döngüsellik, döngüselliğe getirilen eleştiri ve Wierzbicka’nın kuramının tanıtılmasıyla Türkçe sözlüklerde görülen döngüsellik ve döngüselliğin aşılması çerçevesinde kurgulanmıştır.

Semboller, soyut veya aşkın kavramları temsil etmek için sıklıkla kullanılan somut varlıklardır. Görünenin ardındaki görünmez gerçeğe işaret eden semboller, insanın derinliğini de ifade etmektedir. Semboller, hem açıklayıcı hem de gizleyici bir niteliğe sahiptir. Bu nedenle sembollerin antik çağlardan bu yana tarih boyunca tüm toplumlarda kullanıldığı görülmektedir. Hem kullanım sıklığı hem de alan çeşitliliği açısından semboller, araştırmacıların ilgisini çekmiş ve çok sayıda disiplinde araştırma konusu olmuştur. Semboller resim, matematik, psikoloji, din, felsefe ve mitoloji gibi çok çeşitli alanlarda kendini göstermektedir. İnsanlarla belirli bağlam dâhilinde iletişim kuran sembol, gösterdiğinden daha derin olan örtük anlamlar taşımaktadır. Bu nedenle, edebî, dinî ve kültürel bağlamlarda bireyler tarafından sıklıkla kullanılan sembollerin genellikle belirli kodlara sahip olduğu açıktır. Birçok kültürde karşılaşılan ve kültürel aktarım için bir kanal görevi gören semboller, dil ve edebiyat alanlarında da önem taşımaktadır. Edebî metinlerde, mitlerde, anlatılarda ve diğer kültürel ifade biçimlerinde gözlemlenen çeşitli semboller arasında lotus çiçeği özellikle dikkat çekmektedir. Hinduizm ve Budizm gibi doğu dinlerinde özel bir öneme sahip olan bu çiçek, Eski Uygur Türkleri arasında da önem kazanmıştır. Budizm'in benimsenmesiyle birlikte Eski Uygurların değişen dinî, siyasi ve kültürel hayatının etkileri zaman içinde yayımlanan metinlerde kendini göstermiştir. Çok sayıda anlama ve evrensel bir yapıya sahip olan lotus çiçeği Budist metinlerde, özellikle de Budizm'in bir kolu olan Vajrayāna okuluna ait metinlerde yaygın bir semboldür. Çiçek, Budist ve Tantrik düşüncede yaratılış, doğum-ölüm-yeniden doğuş, üreme ve saflıkla ilgili olanlar da dâhil olmak üzere büyük öneme sahip kavramları aktarmak için bir araç görevi görmektedir. Ayrıca, lotus çiçeği metinlerde bulunan benzetme ve tasvirlerde saflık ve güzellik gibi benzer anlamları iletmek için kullanılmıştır. Tantrik özellikler taşıyan Eski Uygur metinlerinde lotus çiçeğinin yaygınlığı, Tantrik anlayışın kapalı ve gizemli yapısıyla ilişkilendirilebilir. Çiçek, metinde çeşitli anlamlarına uygun olarak temsil edilmiştir. Bu çalışma, bağlamsal yorumlamaya vurgu yaparak lotus çiçeğinin Eski Uygurca yazılmış metinlerde ifade edilen sembolik anlamlarını aydınlatmayı amaçlamaktadır. Bunu yaparak, anlamları şifreli olan sembollerin bir metni anlama ve yorumlamada oynadığı önemli rolün altını çizmek amaçlamaktadır.

The current posture adjustment and docking of various engine models typically rely on rigid tooling for support and locking, with the position and posture of the engine being confirmed and adjusted manually. Such docking methods often come with issues such as intense labor, low assembly efficiency, and lengthy assembly cycles. To address these problems, this paper takes the common aircraft engine as the research object and builds an automatic engine docking system. In the AMESim software, a theoretical model of Diverter-regulated cylinder position control is established. Parameters are adjusted based on different working condition parameter scenarios, and the variation curves of parameters such as pressure and flow rate over time under different working conditions are measured to analyze the actual operating status of the system. In the Simulink software, the Diverter-regulated cylinder position control system is reestablished. Sensitivity is used to analyze the Diverter-regulated cylinder unit, and the first-order sensitivity equation and the first-order sensitivity matrix are established. The values of each state variable of the system are extracted in real time using the simulation platform to obtain the sensitivity of the system to each parameter and obtain the optimal solution for each parameter, ensuring the high-precision response of each adjusting leg. The high-precision automatic mounting of the engine is achieved through numerical simulation.

With the development of soft robotics, soft robotic hands are increasingly attracting attention. Compared with their rigid counterparts, they are safer, more adaptive, and lower cost. However, most studies have focused on the soft fingers and actuators, while the significance of the palm is usually overlooked. In this study, a pneumatic fully soft anthropomorphic hand with an active soft palm is proposed. With 12 degrees of freedom (2 in the palm), the soft robotic hand can execute metacarpal and thumb opposition motions. The hand was made using the mold casting method, and the strain energy density function of the silicone rubber is employed in the Yeoh model to calculate the relationship between the air pressure and the bending angle. Next, we tested the bending angle of the fingers and the palm under different air pressure, and grasped objects with various sizes, shapes, and weights, demonstrating good grasping ability. This soft hand can further broaden the potential applications of robotic hands.

Published: December 2024

The State of Charge (SoC) of an electric vehicle plays a crucial role in its performance. SOC can be used to accurately formulate an electric vehicle charge control strategy, which can improve the vehicle’s endurance, reliability, and cost. This paper introduces a new feature parameter as an improvement to the Adaptive Forgetting Factor Recursive Least Squares (AFFRLS) algorithm. The new parameter is designed to capture the dynamics of innovation, thus optimizing the battery model parameter estimation process, and improving its accuracy. Moreover, a function with adjustable parameters was developed with the objective of dynamically determining the optimal value of the forgetting factor. In this paper, the improved AFFRLS algorithm is referred to as the IAFFRLS algorithm. Additionally, we enhance the Adaptive Extended Kalman Filter (AEKF) algorithm by introducing an innovative threshold detection mechanism, thereby optimizing its estimation process. Specifically, the Sage-Husa estimator is employed to adjust the process noise covariance and the measurement noise covariance when the innovation falls below a specified threshold. Conversely, when the innovation exceeds the defined threshold, the algorithm maintains the current parameter state to avoid unnecessary adjustments, effectively minimizing computational burden and the risk of error accumulation during the estimation process. Similarly, the improved AEKF algorithm is hereafter referred to as the IAEKF algorithm. Furthermore, a process for lithium battery SOC estimation using the IAFFRLS-IAEKF joint algorithm is described. To conclude, the results of a series of simulations and experiments demonstrate that the IAFFRLS parameter identification accuracy is higher than the AFFRLS algorithm, and the IAFFRLS-IAEKF joint algorithm outperforms the IAFFRLS-AEKF joint algorithm in terms of accuracy. The effectiveness of the algorithm proposed in this paper has been validated.

To analyze the energy flow in the area, trace the flow path of energy categories used in thermal power generation in the energy system, establish the connection relationship between the energy, power system and the total carbon emission control, and form the power system carbon emission evolution path established by the equilibrium theory method, meeting the goal of GDP growth and global temperature rise carbon budget constraints. The deduction model predicts the installed capacity and the distribution infomation of coal and natural gas power in the future carbon peak stage, as well as the distribution and utilization of renewable energy. China’s energy activities carbon emissions will peak in 2027 and renewable energy installed capacity will reach 1.84 billion kilowatts. Considering the optimization of DC operation curve and system reserve capacity, the peak shaving capacity will be further released by 60 million kilowatts, with the 100 million kilowatts energy storage to ensure the safe and stable operation of power.

Published: December 2024

Haptics, besides visual and auditory sensing, is the third important sensing technology for human-computer interaction. In this paper, a pressure sensor for haptic sensing is designed and demonstrated. The sensor comprises active carbon-based thin film transistor (TFT) and piezoresistive film (PF). The sensing area is fabricated to 0.5 mm × 0.5 mm, which equals human skin’s 1 mm spatial resolution. In the experiment, the sensor can suffer an extensive range of pressure, about 1000 kPa. Additionally, the relationship between sensing current and pressure is linearly fitted at higher pressure with Pearson’s R of 0.976 and R2 of 0.953. Moreover, the active TFT-based sensor realizes an ultrahigh crosstalk suppression of 78.5 dB. More importantly, since the carbon material has the merit of bending, our sensor can be further fabricated to be flexible shortly.
