Όψεις της αναπαράστασης του μαθητικού ρόλου στον ελληνικό κινηματογράφο
Authors: Παπαναστασίου Παναγιώτης
Published: January 2025

Η κινηματογραφική αναπαράσταση του μαθητή στη διεθνή και ελληνική βιβλιογραφία μπορεί να χαρακτηριστεί ως στερεοτυπική, κατασκευασμένη από ενήλικους, αναντίστοιχη, έστω εν μέρει, με την πραγματικότητα, ενώ αποκλείει ζητήματα που απασχολούν τους πραγματικούς μαθητές και τους γονείς τους (σχολική εκπαίδευση), καθώς και κάποιες κατηγορίες μαθητών (π.χ. μαθητές σε δυσμενείς συνθήκες διαβίωσης, σε μη αστικά κοινωνικό-οικονομικά περιβάλλοντα, με προβλήματα υγείας, κ.ο.κ.). Θεωρώντας ότι η παραπάνω θέση δεν αποσαφηνίζεται πλήρως και επαρκώς, η παρούσα θεωρητική μελέτη επιδιώκει να χαρτογραφήσει την κινηματογραφική εικόνα του μαθητή και την ένταξή του στο σχολικό περιβάλλον διερευνώντας τα σημεία εκείνα που δεν αναφέρονται στη διεθνή και ελληνική βιβλιογραφία και μη λησμονώντας βεβαίως, ότι κάθε χαρτογράφηση δεν είναι παρά μία εντελώς υποκειμενική πρόταση ανάγνωσης ενός ανεξερεύνητου, μέχρι στιγμής, χώρου. Με την οπτική αυτή, χαρτογραφείται ο μαθητής σφαιρικά μέσα από ένα αντιπροσωπευτικό δείγμα ταινιών του ελληνικού κινηματογράφου (κλασικός και σύγχρονος), ώστε να παρουσιαστούν οι κοινωνικές και πολιτικές καταστάσεις που αντιμετωπίζει ο μαθητικός ρόλος στο πλαίσιο του εκπαιδευτικού θεσμού και παράλληλα να αναδυθεί ο έμφυλος ρόλος του.

Το παρόν άρθρο αναφέρεται στη διαδικασία δημιουργίας του εκπαιδευτικού ντοκιμαντέρ «Εβηβ[ί]α», το οποίο δημιουργήθηκε στα πλαίσια του μαθήματος «Ανάπτυξη Ψηφιακού Οπτικοακουστικού Υλικού» με διδάσκοντα τον κύριο Σοφό Αλιβίζο. Το θέμα του ντοκιμαντέρ αφορά στη βία των ανηλίκων και προορίζεται για εκπαιδευτικά αξιοποίηση στη διδασκαλία του μαθήματος της «Κοινωνικής και Πολιτικής Αγωγής» της Γ΄ Γυμνασίου, με στόχο την καλλιέργεια προβληματισμού και ευαισθητοποίησης των μαθητών, σχετικά με το φαινόμενο της νεανικής βίας. Το περιεχόμενο του ντοκιμαντέρ καλύπτει διαφορετικές μορφές βίας, όπως σωματική, λεκτική, ψυχολογική, σεξουαλική βία, κυβερνοεκφοβισμό κ.λ.π. Στην Ελλάδα, η νεανική βία παρουσιάζεται κυρίως σε χαμηλή και μεσαία ένταση, όμως μετά την πανδημία παρατηρείται αύξηση των περιστατικών, καθώς και μείωση του ορίου ηλικίας κατά το οποίο ανήλικοι εμπλέκονται σε βίαια αδικήματα. Σημαντικό ρόλο διαδραματίζει η οικογένεια, ιδιαίτερα σε περιπτώσεις όπου υπάρχουν σοβαρά ψυχολογικά προβλήματα ή εξαρτήσεις. Τα περιστατικά βίας επικεντρώνονται στις αστικές περιοχές, όπου η έλλειψη κοινωνικής συνοχής και η παρορμητικότητα των εφήβων επιδεινώνουν το φαινόμενο. Μέσα από συνεντεύξεις ειδικών, δραματοποίηση και οπτικοακουστικά μέσα, το ντοκιμαντέρ επιδιώκει να αναδείξει τα αίτια της βίας, τις κοινωνικές δομές που την ενισχύουν και τις πιθανές λύσεις για την πρόληψη του φαινομένου.

Η παρούσα εργασία διερευνά το ολλανδικό κοινοτικό σχολείο της Αθήνας στο οποίο φοιτούν μαθητές/τριες οι οποίοι/ες προέρχονται από οικογένεια με τουλάχιστον έναν/μία Ολλανδό/ή γονέα. Τα κοινοτικά σχολεία (community schools) στοχεύουν, στην πλειονότητα των περιπτώσεών τους, τόσο στο ελληνικό όσο και στο διεθνές συγκείμενο, στη γλωσσική διατήρηση της ‘μειονοτικής’ γλώσσας, της γλώσσας καταγωγής. Επίσης, η φοίτηση παιδιών σε κοινοτικό σχολείο θεωρείται μια ισχυρή γλωσσική πρακτική εκ μέρους οικογενειών με μεταναστευτικό υπόβαθρο, στο πλαίσιο της θεωρίας της ‘οικογενειακής γλωσσικής πολιτικής’ (family language policy). Παράλληλα, η γλωσσική πολιτική και ο γλωσσικός σχεδιασμός (language policy and planning, LPP) θεωρούνται ένας σημαντικός παράγοντας που συμβάλλει στη γλωσσική διατήρηση και, υπό αυτό το πρίσμα εξετάζεται στην παρούσα εργασία το ολλανδικό κοινοτικό σχολείο της Αθήνας: πώς προσλαμβάνεται η ολλανδική γλώσσα και η διδασκαλία της στο πλαίσιο του συγκεκριμένου κοινοτικού σχολείου και των οικογενειών, των οποίων τα παιδιά φοιτούν στο εν λόγω κοινοτικό σχολείο και ποια ζητήματα γλωσσικής πολιτικής και γλωσσικού σχεδιασμού αναδύονται. Για την διερεύνηση αυτών των ερωτημάτων διεξήχθησαν συνεντεύξεις με γονείς και εκπαιδευτικούς του σχολείου. Η ανάλυση των δεδομένων ανέδειξε τον γλωσσικό σχεδιασμό και τη στοχοθεσία του κοινοτικού σχολείου, που διαφέρει από λοιπές περιπτώσεις κοινοτικών σχολείων στον ελληνικό χώρο.

Published: January 2025

Ένας σημαντικός αριθμός μαθητών και μαθητριών, συμπεριλαμβανομένων των μαθητών/τριών πρωτοβάθμιας εκπαίδευσης, αντιμετωπίζει σε κάποιο βαθμό προβλήματα ψυχικής υγείας. Η πρόληψη, ο εντοπισμός και η υποστήριξη τέτοιων δυσκολιών μέσα στο σχολικό πλαίσιο θεωρούνται κρίσιμα, καθώς το σχολείο είναι συνήθως το πρώτο και μοναδικό μέρος όπου τα παιδιά λαμβάνουν υποστήριξη. Οι εκπαιδευτικοί μπορεί να διαδραματίσουν έναν σημαντικό ρόλο στην προαγωγή της ψυχικής υγείας των μαθητών και μαθητριών τους, αλλά μπορεί επίσης να αισθάνονται ότι χρειάζονται και οι ίδιοι/ες στήριξη σε αυτόν τον ρόλο. Σκοπός της παρούσας έρευνας ήταν να εξετάσει πώς οι αντιλήψεις των εκπαιδευτικών σχετικά με δυσκολίες ψυχικής υγείας των μαθητών/τριών τους επηρεάζουν την αναζήτηση στήριξης των εκπαιδευτικών, όταν δηλαδή αναζητούν υπηρεσίες τεχνικής συμβουλευτικής και επιδιώκουν τη συνεργασία με επαγγελματίες ψυχικής υγείας στο σχολείο (π.χ., ψυχολόγους). Εκπαιδευτικοί πρωτοβάθμιας εκπαίδευσης στην Δυτική Θεσσαλονίκη (N = 124) συμπλήρωσαν ηλεκτρονικά ένα ερωτηματολόγιο που αποτελούνταν από δημογραφικού τύπου ερωτήσεις, κλίμακες που μετρούσαν την αντιλαμβανόμενη επάρκεια, την αντιλαμβανόμενη ευθύνη και τα αρνητικά συναισθήματα των εκπαιδευτικών ως προς τη ψυχική υγεία των μαθητών/τριών τους, καθώς και τρεις κλίμακες που αφορούν την εφαρμογή της τεχνικής συμβουλευτικής και συγκεκριμένα την αποδοχή, την καταλληλότητα και το πόσο εφαρμόσιμη είναι στο σχολικό πλαίσιο. Τα αποτελέσματα έδειξαν ότι το υψηλό αίσθημα ευθύνης των εκπαιδευτικών για ζητήματα ψυχικής υγείας των μαθητών/τριών τους φαίνεται να προβλέπει θετικά την απόφασή τους να αξιοποιήσουν την τεχνική συμβουλευτική. Επιπλέον, το αν την αξιολογούν ως κατάλληλη και αν την αποδέχονται δε φάνηκε να επηρεάζει την επιλογή τους για αξιοποίησή της. Τα αποτελέσματα πλαισιώνονται εντός της ευρύτερης δημοσιευμένης βιβλιογραφίας. Παρουσιάζονται ερευνητικές προεκτάσεις και προτάσεις για εφαρμογή.

Με το παρόν κείμενο, επιχειρούμε να συζητήσουμε κριτικά τον τρόπο με τον οποίο η παιδική ηλικία και η γονεϊκότητα με τη μορφή της εντατικής μητρότητας αναπαρίστανται στην ταινία του Baker (2017) The Florida Project. Η ταινία χαρακτηρίστηκε ως αντιπροσωπευτικό δείγμα του κινηματογράφου της επισφάλειας (Berlant, 2011· Sticchi, 2021) , καθώς ακολουθεί τα χνάρια της φθοράς όλων των σχεσιακών πρακτικών που συνδέουν τους κεντρικούς χαρακτήρες, μέσα από εθνικούς, οικονομικούς, πολιτικούς δεσμούς. Η ανάλυση της ταινίας αξιοποιεί το έργο της Berlant «Cruel Optimism» (2011) και τον κινηματογράφο της επισφάλειας για να διερευνήσει κριτικά τις κατασκευές της παιδικής ηλικίας και της οικογένειας στον νεοφιλελευθερισμό. Χρησιμοποιώντας ως μεθοδολογία την κειμενική φιλμική ανάλυση και την πολιτισμική κριτική, η ταινία του Baker προσφέρει μια οπτική των τρόπων με τους οποίους τα παιδιά διαπραγματεύονται με συναισθηματικές χρονικότητες και με τη φαντασία τα βιωμένα αδιέξοδα μιας οικογενειακής ζωής σε καθεστώς επιτήρησης και ελέγχου. Η ταινία αντιστέκεται σε αφηγήσεις θυματοποίησης και παθολογικοποίησης και δυνητικά συντελεί στην επίγνωση των νεοφιλελεύθερων μετασχηματισμών των υποκειμένων και της κοινωνίας. Δυνητικά, αντίστοιχα είδη ταινιών παρέχουν ένα κριτικό λεξιλόγιο στην παιδαγωγική που προβληματικοποιεί απλοϊκές παραδοχές για την αναπτυξιακή μετάβαση από την αθωότητα στην εμπειρία, από την παιδική ηλικία στην ενηλικότητα. Τελικά, το  The Florida Project σηματοδοτεί ένα σύνθετο σημείο καμπής για τις οικογένειες στην ύστερη νεωτερικότητα, συνηγορώντας για την ενεργητική δράση της παιδικής ηλικίας και αναδεικνύοντας τα αδιέξοδα θεσμικών κρατικών παρεμβάσεων για «περιθωριοποιημένες» οικογένειες.

Optimization of Catfish Pond Water pH with PID Control using Outseal PLC
Authors: Rachman Abdillah Ali , Ariandi Muhamad
Published: January 2025

The increasing need for national consumption fish every year makes the business of cultivating consumption fish such as catfish increasingly developed. In catfish farming, the pH level factor in water affects the growth and development of catfish. If the pH level is not appropriate, it causes catfish disease and catfish appetite decreases. So it is necessary to control the pH level of water automatically which makes it easy to maintain pH levels in fish ponds using PID control. The system is designed using Outseal which is an Arduino bootloader-based PLC (Progammable Logic Control) which is open source at an affordable price connected to the RDD-AFE-001 sensor to send readings of actual pH levels into the PID control process. The PID output is in the form of a pwm value to run the L2890N motor driver as a nutrient pump speed regulator based on the pH value. The results of analyzing the value of PID parameters using simulink software obtained the value of Kp = 30, Ki = 20 and Kd = 15. The Propotional role produces a better rise time so that the pH sensor reading response is faster, then the integral role eliminates overshoot which causes more accurate sensor readings and the derivative role eliminates steady state errors that affect the stability of the pH sensor reading. The test results successfully maintain the pH level in water with a value of 7.0 with water temperatures ranging from 26 ° C - 30 ° C. The existence of this system can increase the growth and stability of the pH sensor reading. With this system can improve the growth and development of catfish and away from contracting diseases and facilitate farmers in terms of maintaining the pH level of catfish water.

Published: January 2025

Flood detection devices and water levels from several previous research studies were not optimal because they were still running and manual information, such as through loudspeakers, in some research, electronic devices have been used, but no information has been obtained, and it is not optimal if there is a danger sign. So this research is a study on the development of an automatic flood detection system and water level based on the IoT (Internet of Things). The system uses a NodeMCU Esp8266 controller with a combination of potentiometer sensors mounted on a water-level mechanic and connected to the Thingspeak IoT platform. Based on the results of the analysis and testing that have been done, the system is designed to combine the previous research algorithms so that it works more optimally and is better. The flood detection system and water level are made in two parts: one is placed upstream and the other is placed downstream, where the devices are connected. The device will turn on a danger alert when the altitude percentage is more than 85% of the maximum height. The lag time in the upload and download process is included in the Fast category (≤10 seconds). The resulting information can be monitored through the media portal website.
Fuzzy A* for optimum Path Planning in a Large Maze
Authors: Airlangga Gregorius
Published: January 2025

Traditional A* path planning, while guaranteeing the shortest path with an admissible heuristic, often employs conservative heuristic functions that neglect potential obstacles and map inaccuracies. This can lead to inefficient searches and increased memory usage in complex environments. To address this, machine learning methods have been explored to predict cost functions, reducing memory load while maintaining optimal solutions. However, these require extensive data collection and struggle in novel, intricate environments. We propose the Fuzzy A* algorithm, an enhancement of the classic A* method, incorporating a new determinant variable to adjust heuristic cost calculations. This adjustment modulates the scope of scanned vertices during searches, optimizing memory usage and computational efficiency. In our approach, unlike traditional A* heuristics that overlook environmental complexities, the Fuzzy A* employs a dynamic heuristic function. This function, leveraging fuzzy logic principles, adapts to varying levels of environmental complexity, allowing a more nuanced estimation of the path cost that considers potential obstructions and route feasibility. This adaptability contrasts with standard machine learning-based solutions, which, while effective in known environments, often falter in unfamiliar or highly complex settings due to their reliance on pre-existing datasets. Our experimental framework involved 100 maze-solving trials in diverse maze configurations, ranging from simple to highly intricate layouts, to evaluate the effectiveness of Fuzzy A*. We employed specific metrics such as path length, computational time, and memory usage for a comprehensive assessment. The results showcased that Fuzzy A* consistently found the shortest paths (99.96% success rate) and significantly reduced memory usage by 67% and 59% compared to Breadth-First-Search (BFS) and traditional A*, respectively. These findings underline the effectiveness of our modified heuristic approach in diverse and challenging environments, highlighting its potential for real-world pathfinding applications.

Authors: Airlangga Gregorius
Published: January 2025

This study explores the application of Particle Swarm Optimization (PSO) in Unmanned Aerial Vehicle (UAV) path planning within a simulated three-dimensional environment. UAVs, increasingly prevalent across various sectors, demand efficient navigation solutions that account for dynamic and unpredictable elements. Traditional pathfinding algorithms often fall short in complex scenarios, hence the shift towards PSO, a bio-inspired algorithm recognized for its adaptability and robustness. We developed a Python-based framework to simulate the UAV path planning scenario. The PSO algorithm was tasked to navigate a UAV from a starting point to a predetermined destination while avoiding spherical obstacles. The environment was set within a 3D grid with a series of waypoints, marking the UAV's trajectory, generated by the PSO to ensure obstacle avoidance and path optimization. The PSO parameters were meticulously tuned to balance the exploration and exploitation of the search space, with an emphasis on computational efficiency. A cost function penalizing proximity to obstacles guided the PSO in real-time decision-making, resulting in a collision-free and optimized path. The UAV's trajectory was visualized in both 2D and 3D perspectives, with the analysis focusing on the path's smoothness, length, and adherence to spatial constraints. The results affirm the PSO's effectiveness in UAV path planning, successfully avoiding obstacles and minimizing path length. The findings highlight PSO's potential for practical UAV applications, emphasizing the importance of parameter optimization. This research contributes to the advancement of autonomous UAV navigation, indicating PSO as a viable solution for real-world path planning challenges.

Authors: Airlangga Gregorius
Published: January 2025

In the realm of Unmanned Aerial Vehicles (UAVs), efficient navigation in complex environments is crucial, necessitating advanced pathfinding algorithms. This study introduces the Fick's Law Algorithm (FLA) for UAV path optimization, drawing inspiration from the principles of molecular diffusion, and positions it in the context of existing algorithms such as A* and Dijkstra's. Through a comparative analysis, we highlight FLA's unique approach and advantages in terms of computational efficiency and adaptability to dynamic obstacles. Our experiment, conducted in a simulated three-dimensional space with static and dynamic obstacles, involves an extensive quantitative analysis. FLA's performance is quantified through metrics like path length reduction, computation time, and obstacle avoidance efficacy, demonstrating a marked improvement over traditional methods. The technical foundation of FLA is detailed, emphasizing its iterative adaptation based on a cost function that accounts for path length and obstacle avoidance. The algorithm's rapid convergence towards an optimal solution is evidenced by a significant decrease in the cost function, supported by data from our convergence graph. Visualizations in both 2D and 3D effectively illustrate the UAV’s trajectory, highlighting FLA's efficiency in real-time path correction and obstacle negotiation. Furthermore, we discuss FLA's practical implications, outlining its adaptability in various real-world UAV applications, while also acknowledging its limitations and potential challenges. This exploration extends FLA's relevance beyond theoretical contexts, suggesting its efficacy in real-world scenarios. Looking ahead, future work will not only focus on enhancing FLA's computational efficiency but also on developing specific methodologies for real-world testing. These include adaptive scaling for different UAV models and environments, as well as integration with UAV hardware systems. Our study establishes FLA as a potent tool for autonomous UAV navigation, offering significant contributions to the field of dynamic path optimization.

Published: January 2025

PT SINAR INDOGREEN KENCANA is a company that produces AAC (Autoclave Aerated Concrete) lightweight bricks, the existence of a limestone grinding machine (Mill MTW) into lime powder and maturation of raw materials with the steam process of the autoclave machine, as well as the occurrence of rain that disrupts air circulation in the production area, causing a lot of dust and hot water vapor from the machining process to enter the production area, thus disrupting the performance of employees. This research aims to design a prototype blower for air quality control in the production area of PT SINAR INDOGREEN KENCANA. Where this system is designed to control and monitor dust and temperature levels, utilizing ESP8266 as a monitoring unit and Arduino UNO as a controller, with Blynk integration as a user interface. In operation, ESP8266 monitors dust levels and temperature through the I2C LCD, turning on the blower to suck dust and water vapor from the remaining hot production. Arduino UNO as a link between the GP2Y1010AU0F sensor for dust detection and the DHT22 sensor for temperature detection, sends data on dust levels and temperature to ESP8266. Through the BLYNK application, users can find out dust levels, temperature, and whether the blower is on or off. The application of this system obtained the result that the whole system provides an integrated and effective solution for controlling air quality in the production area of PT SINAR INDOGREEN KENCANA.

Published: January 2025

In this paper, we aim to review current methods of energy harvesting, focusing on piezoelectric energy. To optimize the use of piezoelectric devices in applications, a model is needed to observe the performance generated from piezoelectricity. To achieve better performance, the rectifier and capacitor systems are connected to a boost converter circuit. Another method is to use the Synchronized Switch Harvesting Inductor (SSHI) method. This method implements a stand-alone switching technique based on transistors and rectifier diodes and does not require an external power supply. This research creates an electric energy harvesting floor device by utilizing piezoelectricity in the form of a harvester, which aims to find out how piezoelectric works and to obtain a circuit with the most efficient characteristics as a piezoelectric power generator using SSHI and a boost converter. This study compares the characteristics of series, parallel, and series-parallel circuits on the floor of the most optimal piezoelectric energy harvester to generate voltage. The results of the data collection were based on the number of steps on the floor of the 16-piece piezoelectric energy harvester with a series-parallel circuit configuration connected with an SSHI circuit and without an SSHI circuit. In this test, the resulting voltage output is a DC voltage with an input step of 60 times the step on piezoelectricity. In this paper, an energy harvester using the SSHI circuit provides a more stable voltage on the harvester floor than a boost converter by providing 16 piezoelectric pieces arranged in series parallel. A floor energy harvester with a series-parallel configuration connected to SSHI gets the most optimal result compared to using a boost converter.

Published: January 2025

Bangkok Chicken (Gallus Gallus Domesticus) is a type of chicken in Indonesia that has a high source of protein and supports the community's economy. The growth and development phase of chicks is a critical period because chicks are very vulnerable to attacks by infectious and non-infectious diseases. These diseases can cause high mortality rates and cause significant economic losses for farmers. This study aimed to investigate the potential for using CNN technology in the early detection of disease in Bangkok chicks in the Ponorogo district. As an artificial neural network, CNN can recognize patterns in visual data with high accuracy. The use of CNN technology in the agricultural sector, including animal husbandry, has shown promising results in supporting early disease detection systems in livestock. This study aims to investigate the potential of using CNN technology in the early detection of disease in Bangkok chicks in the Ponorogo district. By processing visual data from chicken images, CNN will be trained to identify early signs of disease in chicks. The result of this research is that this research can help maintain the availability and security of animal food supplies, which is an essential component of overall food security. In addition, by reducing losses caused by disease, this research can contribute to sustainable agriculture by ensuring the continuation of stable and sustainable animal food production.
Atomic quadrupolar fluorescence in the presence of a spherical nanoantenna: cesium 6S1/2 − 6D5/2
Authors: Zurita-Sánchez Jorge R.
Published: January 2025

We examine the fluorescence of a quadrupolar transition occurring in a three-level atom near a spherical nanoantenna with plane-wave excitation; the atom can be only excited by means of a quadrupolar transition, and it can decay either by a direct quadrupolar transition or a ladder decay composed of two dipolar transitions. Since dipolar transitions are unavoidable, fluorescence from them is also studied. Specifically, we analyze the fluorescence rates of the radiative transitions of the cesium atom (6S1/2−6D5/2), as well as the involving competing processes, namely, the excitation rate and quantum yield. In relation to the case without a nanoantenna: (1) the quadrupolar quantum yield can be enhanced by about 2.55 orders of magnitude; (2) the excitation rate of the quadrupolar transition reaches an enhancement between 2 and 3.7 orders of magnitude; (3) because of the simultaneous enhancement of the excitation rate and quantum yield, the quadrupolar fluorescence rate can be enhanced by 4.7 orders of magnitude, enabling the practical detection of the fluorescence from the quadrupolar transition, whereas the dipolar fluorescence rates are augmented about 2.18 orders of magnitude. These findings occur when the atom is placed in an interval less than 10 nm from the surface of the nanoantenna. In addition, even in the presence of the nanoantenna, the quadrupolar fluorescence rate is smaller than the dipolar one; the ratio of these quantities with respect to its free-space value can be improved at most 2.3 orders of magnitude. Our setup is simple for practical implementation; hence, our work might impact applications related to atomic spectroscopy and sensing as well as control and manipulation of light emission and quantum states.
Towards 250-m gigabits-per-second underwater wireless optical communication using a low-complexity ANN equalizer

Published: January 2025

The breakthroughs in communication distance and data rate have been eagerly anticipated by scientists in the area of underwater wireless optical communication (UWOC), which is seriously limited by the obvious aquatic attenuation in underwater channels. The high-power laser source and ultra-sensitive photodetector are straightforward in extending the UWOC distance. However, nonlinear impairments caused by bandwidth-limited high-power transmitters and sensitive receivers severely degrade the data rate of long-distance UWOC. In this paper, we develop a UWOC system using a high-power transmitter by beam combining of 8-channel cascaded laser diodes (LD) and a sensitive receiver by a silicon photomultiplier (SiPM). The combined linear equalizer and low-complexity artificial neural network (ANN) equalizer are used to robustly achieve 1-Gbps data transmission over a 250-m UWOC system. To the best of our knowledge, this is the first Gbps-level UWOC experimental demonstration in >250-meter underwater transmission that has ever been reported. To lower the complexity of the ANN equalizer, a linear equalizer is applied first in order to prune the input size of the ANN equalizer. The optimal input size of the ANN equalizer is identified as 9. The ANN architecture consists of two hidden layers, with 10 neurons in the first layer and a single neuron in the second layer. The performance of the proposed ANN-based system is compared with that of systems employing Volterra and linear equalizers. The bit error rate (BER) at a data rate of 1 Gbps over a 250-m UWOC is reduced to 3.4 × 10−3 with the combined linear and ANN equalizer, which is below the hard-decision forward error correction (HD-FEC) limit. In contrast, the linear and Volterra equalizer-based systems achieve data rates of 500 Mbps and 750 Mbps, respectively.

Published: January 2025

Here we report a simple self-masking technique for fabricating bioinspired broadband antireflection coatings on both single-crystalline and multicrystalline silicon wafers with the assistance of a polyimide tape. Subwavelength-structured moth-eye nanopillars, which exhibit superior antireflection performance over a broad range of visible and near-IR wavelengths, can be patterned uniformly on the wafer surface by applying a chlorine-based reactive ion etching (RIE) process. The resulting random nanopillars show improved antireflection properties compared with ordered nanopillars templated by colloidal lithography under the same RIE conditions. X-ray photoelectron spectroscopy analysis suggests that energetic bombardment by reactive ions and radicals during RIE sputters the polyimide tape and spontaneously forms nanomasks over the wafer.

Published: January 2025

We report our design and fabrication of a laterally coupled tighten-ridge-waveguide distributed feedback (LC-TRWG-DFB) laser with 37th-order sidewall gratings and 30 µm ridge width. Unlike the LC-DFB lasers with narrow ridge waveguides, our proposed LC-TRWG-DFB improves the output power by widening the width of the ridge waveguide. Simultaneously, the reduction of grating coupling ability and the emergence of high-order lateral modes caused by the widening are mitigated by the tighten structure at the rear of the ridge waveguide. Experimental results demonstrate that by using the tighten-ridge-waveguide, the spectral width is narrowed from 0.72 nm to 0.07 nm, and the temperature-dependent shift in wavelength is reduced from 0.2 nm/K to 0.12 nm/K at 0.4 A. Compared to the LC-DFB laser, the maximum output power of the LC-TRWG-DFB is increased from 136 mW to 328 mW. This study provides valuable insights for the development of high-power LC-DFB semiconductor lasers with a simple fabrication process.

Published: January 2025

We demonstrate the feasibility of swept-source visible-light optical coherence tomography (SS-vis-OCT). We used a fanout periodically poled lithium niobate (PPLN) crystal for second-harmonic generation (SHG) to convert a commercial near-infrared swept-source (NIR-SS) laser into a visible-light SS laser. To enhance SHG efficiency, we amplified the NIR-SS output with booster optical amplifiers (BOAs) and generated up to 580 µW of power. The SS-vis-OCT achieved a maximum axial resolution of 7.3 µm and an imaging depth of 5 mm in air, corresponding to 5.4 µm and 3.7 mm in tissue (n = 1.35). Compared with spectral-domain vis-OCT, SS-vis-OCT provides a 2.2-fold increased imaging depth and a 2.8-fold improved roll-off. Additionally, we validated SS-vis-OCT performance using a 3D-printed pyramid phantom, with its feature measurements cross-validated by scanning electron microscopy (SEM).

Published: January 2025

Optical projection tomography (OPT) is an imaging technology that employs light to reconstruct 3D models of objects. Recent advancements in neural radiance field (NeRF) have improved 3D biomedical imaging, yet they perform suboptimally with low signal-to-noise ratio (SNR) data in low-cost setups and are not directly applicable to OPT systems. Here, we introduce neural optical projection tomography (NeOPT), leveraging a low-cost OPT imaging setup combined with a pose-robust neural-based 3D reconstruction method to achieve high-quality OPT results. NeOPT incorporates discrete wavelet transform (DWT) to reduce imaging noise under low-SNR conditions. Experiments demonstrate that NeOPT significantly outperforms traditional OPT techniques.
