Finite-valued Streaming String Transducers
Authors: Filiot Emmanuel , Jecker Ismaël , Puppis Gabriele , Löding Christof , Muscholl Anca , Winter Sarah
Published: January 2025

A transducer is finite-valued if for some bound k, it maps any given input to at most k outputs. For classical, one-way transducers, it is known since the 80s that finite valuedness entails decidability of the equivalence problem. This decidability result is in contrast to the general case, which makes finite-valued transducers very attractive. For classical transducers, it is also known that finite valuedness is decidable and that any k-valued finite transducer can be decomposed as a union of k single-valued finite transducers. In this paper, we extend the above results to copyless streaming string transducers (SSTs), answering questions raised by Alur and Deshmukh in 2011. SSTs strictly extend the expressiveness of one-way transducers via additional variables that store partial outputs. We prove that any k-valued SST can be effectively decomposed as a union of k (single-valued) deterministic SSTs. As a corollary, we obtain equivalence of SSTs and two-way transducers in the finite-valued case (those two models are incomparable in general). Another corollary is an elementary upper bound for checking equivalence of finite-valued SSTs. The latter problem was already known to be decidable, but the proof complexity was unknown (it relied on Ehrenfeucht's conjecture). Finally, our main result is that finite valuedness of SSTs is decidable. The complexity is PSpace, and even PTime when the number of variables is fixed.

Артериовенозная мальформация матки (АВМ) – это аномальное соединение между артериями и венами, которое может явиться опасным для жизни источником кровотечения. Обычно у пациенток с АВМ наблюдается вагинальное кровотечение после аборта (медикаментозного/хирургического) или кесарева сечения. Выбор метода лечения АВМ зависит от симптомов, возраста, желания сохранить фертильность, локализации и размера поражения. Мы сообщаем о случае АВМ у пациентки с неразвивающейся беременностью в рубце после кесарева сечения, проявившейся после медикаментозного прерывания неразвивающейся беременности с последующей вакуум-аспирацией.

Uterine arteriovenous malformation (AVM) is an abnormal connection between arteries and veins that can be a life-threatening source of bleeding. Typically, patients with AVM present with vaginal bleeding after abortion (medical/surgical) or cesarean section. The choice of treatment for AVM depends on symptoms, age, desire to preserve fertility, location and size of the lesion. We report a case of AVM in a patient with a nonviable pregnancy in a cesarean section scar that presented after medical termination of the nonviable pregnancy followed by vacuum aspiration.

Published: January 2025

The resumption of postpartum ovarian ac-tivity (RPOA) is influenced by the cow’s meta-bolic profile, though the relationship betweenRPOA and the metabolic profile of dairy cowsat high altitude in the Andean Region of Ecua-dor is still unclear. The goal of this study was todetermine the relationship between RPOA andthe metabolic profile of Holstein cows at highaltitude in the Andean Region of Ecuador. Thir-ty cows were selected and their RPOA and met-abolic profile at 30 days postpartum were evalu-ated. According to the RPOA, the metabolic in-dicators were compared using the t-Student testfor independent samples. A simple linear cor-relation was run between the main indicatorsof the RPOA and the metabolic parameters. Anobservational analytical study was performedto establish the association between RPOA andmetabolic profile. Holstein caws showing anearly RPOA had lower β-Hydroxybutyrate andblood urea nitrogen (P < 0.05), and higher phos-phate, copper, and zinc concentrations (P < 0.05)concentrations in blood serum as compared toHolstein cows with late RPOA. Increased bloodβ-hydroxybutyrate and low phosphate, copperand zinc were risk factors (P < 0.05) for late post-partum RPOA. In addition, the follow param-eters were correlated (P < 0.05): appearance ofthe dominant follicle and zinc levels, follicle di-ameter and copper, occurrence of ovulation andblood β-hydroxybutyrate level, the occurrenceof ovulation and phosphate , luteal activity andcholesterol, corpus luteum volume and cop-per, blood serum progesterone and cholester-ol, and blood serum progesterone and copperlevels. There was a strong correlation (P < 0.01)between the occurrence of ovulation and cop-per levels, luteal activity and blood β-hydrox-ybutyrate levels, and copper and zinc levels.These findings show that RPOA was related tothe metabolic profile at 30 days postpartum, es-pecially with protein excesses and energy, andphosphate, copper and zinc deficiencies.

Critical Factors and Consequences of Delay in Construction Practices of Bangladesh: Analytical Review
Authors: Chowdhury Md. Rejoan , Mondal Dipto
Published: January 2025

Construction project delays are one of the primary challenges around the world. Bangladesh is not out of this problem. The delay of a project can be due to many reasons. By analyzing lots of research papers and practical inspections, 28 factors of delays in projects in Bangladesh have been sorted out and expressed in the Ishikawa fishbone diagram for easy understanding. To identify the critical factors, a questionnaire-based survey was carried out with the participation of owners, workers, contractors, engineers, and students involved in the relevant sector. The relative importance index (R.I.I.) was used to rank critical factors. The topmost critical factors of delay in Bangladesh’s construction works are scarcity of skilled workers, faulty organization and time management, scarcity of experienced construction managers, improper assessment of progress and cost optimization, and an improper feasibility study. Time overrun, cost overrun, poor quality, dispute, and reputation decline are the leading consequences of delays. Appointing skilled labor and a construction manager, arranging a training program, financial stability, and the availability of resources would be practical factors in reducing project delays.

Oxidative stress is a condition in which the free-radical substance is higher than the potential antioxidant in the human body. Therefore, exogenous antioxidants are needed to resolve this problem. Water lettuce (Pistia stratiotes) is an aquatic floating plant that contains several bioactive compounds, including tannins and exhibits antioxidant activity. However, since organic solvent extraction results in a crude polyphenol extract, purification is needed to remove the undesirable compounds. This study was aimed at determining the total tannin content and antioxidant activity of water lettuce leaf extract before and after the purification process. The purification was done using a solid-phase extraction method, the total tannin contents were analysed using Folin-Ciocalteu’s method, and the antioxidant activity was analysed using 2,2-diphenyl-1-picrylhydrazyl. The results showed that the purification process successfully removed undesirable compounds and increased the total tannin content of the extract from 8.71 ± 1.50 mg TAE/g of the dry sample to 13.84 ± 0.28 mg TAE/g of the dry sample. The antioxidant activities also increased after the purification from IC50 135.14 ± 22.44 µg/mL to IC50 78.45 ± 5.42 µg/mL. According to these results,
the tannin from water lettuce extract can be used as a source of natural antioxidants and formulated as an ingredient in food supplements.

Education is an important aspect in economic resilience. Iraqʼs educational and economic indicators reveal a compelling need to improve educational achievements in order to increase economic resilience. While previous studies have explored the relationships among education, human capital, and economic resilience in Iraq individually, this paper aims to empirically investigate the influence of sustainable education on economic resilience, considering the moderating role of human capital in Iraq from 1990 to 2022. Using the ARDL technique, the findings demonstrate that sustainable education has a positive and significant impact on economic resilience, with an increase in education by one year associated with an approximate 0.04% increase in economic resilience in the
long run. Moreover, the impact of education on economic resilience in Iraq intensifies with higher levels of human capital. Specifically, the marginal effect of education on economic resilience ranges from 0.27 at the minimum level of human capital to 0.33 at the maximum level. Therefore, policymakers in Iraq should focus on improving education quality, promoting lifelong learning, and leveraging technology to enhance educational outcomes and human capital. To further develop human capital, policymakers should create and implement comprehensive programs encompassing education, health, and vocational training.

In today’s dynamic business landscape, effective inventory management is essential for minimizing costs and maximizing profitability. Traditional models like EOQ and JIT often fall short in handling demand and supply uncertainties due to their reliance on precise data. This paper introduces a novel approach that combines fuzzy logic and deep learning to address these limitations. Fuzzy logic offers a robust framework for decision- making under uncertainty, while deep learning improves predictive accuracy by identifying complex patterns in historical data. By transforming data into fuzzy sets and applying neural networks for demand forecasting, the proposed model optimizes inventory levels to reduce costs and prevent stockouts. A mathematical model and algorithmic implementation demonstrate the approach’s effectiveness and a numerical example highlights improvements in inventory control, including reduced holding costs. This study underscores the potential of integrating AI techniques for adaptive, data-driven inventory management with broad applications across various industrial processes.

This paper presents a comparative performance analysis of PVC and MS blades in Archimedes Spiral Hydro Turbines (ASHT) for sustainable hydropower generation. There are two types of ASHT prototypes fabricated based on a three-dimensional (3D) design by varying the blade material; one was Poly Vinyl Chloride (PVC) made screw ASHT, and another was Mild Steel (MS) made ASHT. The thickness of PVC and MS was 4 mm and 1 mm, respectively. The generated voltage and current for 0.5 m, 1.0 m, and 1.5 m heads were analyzed, and the output power was compared with various shaft rotations based on the variation of the head. At the same head, voltage and current were obtained much more for MS-made ASHT. At 1.5m, higher voltage and current were investigated; the voltage and current were 10.2V and 0.57A for MS-made. MS-made ASHT exhibited 52.20% and 23.90% more voltage and current, respectively than PVC-made ASHT at 1.5m head. The maximum power was observed for MS-made ASHT, which was 5.82W at 502 rpm. This paper underscores the importance of balancing design parameters, blade material, and operating conditions to optimize ASHT for sustainable hydropower generation.

Various preventive measures, including vector control, are undertaken to reduce dengue fever infections. This study aims to assess the effectiveness of soursop leaf + lemongrass extract, soursop leaf + papaya leaf extract, and lemongrass + papaya leaf extract at a 50% concentration in controlling the vector of dengue fever using larvicides. In this research, extracts from the aforementioned plants were prepared and tested for their effectiveness against Aedes aegypti larvae. The larvae were exposed to different extract combinations, and their mortality rates were recorded over a specific period. The results were statistically analyzed to determine the significance of the findings. The analysis showed a significant difference in the average mortality of larvae using the soursop leaf + lemongrass extract combination and the soursop leaf + papaya leaf extract combination (p<0.05). These findings highlight the potential use of natural plant extracts in managing mosquito populations, particularly Aedes aegypti.  In efforts to prevent and control dengue fever cases, the use of soursop leaf + lemongrass extract and lemongrass + papaya leaf extract as natural larvicides is recommended. It is crucial for community involvement, public health organizations, and policymakers to adopt natural pest control methods and consider integrating these natural solutions into public health strategies.

Peran Usaha Mikro, Kecil dan Menengah (UMKM) menjadi salah satu peranan yang dominan dalam struktur perekonomian Indonesia. UMKM menghadapi tantangan dalam hal keragaman karakteristik dan kondisi usaha yang berbeda-beda, salah satunya adalah Sentra Wisata Kuliner (SWK). Meskipun banyak SWK terletak di lokasi strategis dengan fasilitas yang memadai, mereka belum memberikan pendapatan optimal bagi para pelaku usaha. Pada penelitian ini dilakukan analisis pengelompokan SWK Usaha Mikro, Kecil, dan Menengah (UMKM) di kota Surabaya Tujuannya adalah untuk mengelompokkan SWK berdasarkan kesamaan karakteristik seperti luas sentra, kapasitas, jumlah pelaku usaha, dan produktivitas menggunakan metode Agglomerative Hierarchical Clustering (AHC). Setelah melalui tahapan pra-pemrosesan data, penentuan metode cluster terbaik menggunakan korelasi cophenetic, dan validasi jumlah cluster optimal dengan silhouette coefficient, diperoleh hasil pengelompokan yang membagi SWK menjadi 3 cluster berdasarkan pengukuran jarak menggunakan single linkage, average linkage, complete linkage, dan ward linkage. Complete linkage memberikan performa yang baik yakni nilai cophenetic sebesar 0.8734 dan nilai silhouette coefficient sebesar 0.4864. Interpretasi cluster yang didapatkan yakni cluster 1 menunjukkan stabilitas dan aktivitas ekonomi tinggi, cluster 2 mencakup mencakup sentra yang kurang berkembang, dan cluster 3 menunjukkan karakteristik sebagai pusat-pusat usaha yang sangat besar dan berhasil. Hasil pengelompokan ini dapat digunakan sebagai dasar untuk merancang strategi dan program pengembangan UMKM secara lebih efektif dan berkelanjutan.

Published: January 2025

Abstrak, Krisis energi global dan isu-isu lingkungan mendorong pengembangan sumber energi berkelanjutan seperti Pembangkit Listrik Tenaga Surya (PLTS). Efisiensi penyerapan energi matahari oleh PLTS untuk penerangan jalan umum masih rendah karena posisi panel surya pada penerangan jalan umum yang statis atau tidak mengalami perubahan posisi. Mengakibatkan panel surya menyerap sinar matahari tidak optimal dan energi listrik yang dihasilkan tidak mencukupi untuk pengisian baterai, sehingga baterai sering mengalami pengosongan dan mengakibatkan penurunan umur pakai atau bahkan rusak. Penelitian ini mengembangkan sistem pelacak matahari Solar Tracking System (STS) berbasis arduino ke dalam miniatur penerangan jalan dengan skala 1:2 sehingga dapat meningkatkan penyerapan energi matahari. Sensor Light Dependent Resistor (LDR) digunakan sebagai sensor pembaca posisi sinar matahari dan menggerakkan motor DC actuator melalui relay yang dikendalikan oleh Arduino Mega. Hasil rancangan ini menunjukkan bahwa panel surya dengan STS menjaga penyerapan radiasi matahari lebih optimal, di mana waktu puncak energi matahari yang dapat diserap panel surya pukul 08.00 hingga 17.30 mencapai 300.30 Wh. Sehingga energi listrik yang dihasilkan tersebut masih tersisa untuk disimpan pada baterai sehingga baterai tetap terjaga terisi setiap hari.

Perkembangan teknologi industri modern menuntut pemahaman yang mendalam tentang penggunaan Programmable Logic Controller (PLC). PLC merupakan perangkat elektronika digital dengan memori yang dapat diprogram untuk menjalankan instruksi khusus seperti operasi aritmetika, pewaktu, pencacah, logika, dan sekuensial guna mengendalikan perangkat dalam suatu sistem. Namun, kurangnya sarana pembelajaran menyebabkan rendahnya tingkat pemahaman mahasiswa mengenai konsep dasar dan praktik PLC. Penelitian ini bertujuan untuk menerapkan aplikasi Factory I/O sebagai media pembelajaran penggunaan PLC bagi mahasiswa Teknik Elektro, dengan fokus pada sebuah studi kasus sistem penyortiran benda logam dan nonlogam. Factory I/O adalah software simulasi yang memungkinkan perancangan dan pengujian sistem kontrol industri secara virtual. Dalam penelitian ini, Factory I/O digunakan untuk merancang simulasi pabrik yang kemudian dikendalikan oleh PLC dan dimonitor melalui HMI. Hasil penelitian menunjukkan bahwa sistem ini berhasil memisahkan benda logam dan nonlogam serta memberikan gambaran nyata tentang implementasi teori di industri. Dengan demikian, aplikasi Factory I/O yang dikombinasikan dengan PLC dan HMI dapat dimanfaatkan sebagai sarana pembelajaran pada mata kuliah PLC.
