Abstract

Communication is a fundamental human need to interact with each other. For children with special needs, particularly children with hearing impairment, communication becomes very important because they must to learn to communicate harder than a normal child. In SLB Karnna Manohara articulation mirror used as a device to train children with hearing impairment in communication, especially in terms of language expression. But the device is less effective because the size is large and not portable. The purpose of this program is implementation Electronic Portable Articulation Mirror (EPAM) which is a modification of a large mirror articulation into a portable, practical and more effective. Implementation of this program is done through several steps, they are observation, device improvements, feasibility test (calibration), evaluation and revision, application of device, and evaluation. The results of this program are EPAM design that consists of a mirror, an LCD display, a control menu, sound indicator light, power indicator light, power button, display baterray checker, 3.5 mm audio port, audio port 7 mm, charger port, speakers, headsets, and microphone. Then for the implementation of EPAM in speech therapy business unit of SLB Karnna Manohara has succeeded in increasing the expression of language ability of deaf children to gain (g) 0.72 and increased capacity with high criteria.Keywords : articulation portable electronic mirror, children with hearing impairment, language expression

Abstract

The purpose of this study was to design and determine the ability of the catfish smoking system automatically using the ATMega8 microcontroller and the LM 35 temperature sensor as an optimization of catfish smoking production, as well as to conduct a comparative study of smoked catfish quality and economic analysis with conventional systems. The type of research used is research and development with a 4D model approach (define, design, develop and desiminate) and comparative analysis. Data obtained through observation, testing and documentation. Then analyzed qualitatively and quantitatively. The results obtained from this study are the design of a catfish smoking system automatically using an ATMega8 microcontroller and a temperature sensor as an optimization of catfish smoking production. The workings of the catfish smoking system is to control the rotation and smoking time using an ATMega8 microcontroller. The smoking system is able to produce 2 kilograms of smoked catfish in 120 minutes with a distance of 40 cm with a quality water content of 58.14%, ash content of 5.93%, pH value of 6.56 and TBA value of 0.02.

Abstract

Penelitian ini bertujuan untuk menganalisis karakteristik kinematika linier tumit selama aktivitas berjalan, berlari, dan berlari cepat sebagai dasar untuk mengevaluasi biomekanika gerak manusia. Metode yang digunakan meliputi perekaman gerak menggunakan kamera dan analisis kecepatan vertikal tumit melalui perangkat lunak analisis gerak berbasis video. Data dikumpulkan dari grafik kecepatan-waktu vertikal dan pengukuran parameter gaya berjalan seperti panjang langkah, durasi fase berdiri dan berayun, frekuensi langkah, dan waktu siklus gaya berjalan. Hasil penelitian menunjukkan bahwa kecepatan vertikal tumit menunjukkan fluktuasi yang khas pada setiap jenis gerakan, dengan amplitudo dan durasi fase yang berubah seiring dengan peningkatan kecepatan gerak. Selama berlari cepat, kecepatan puncak yang sangat tinggi terjadi pada langkah awal, diikuti oleh pola fluktuasi yang lebih teratur. Temuan ini menunjukkan penyesuaian biomekanika yang kompleks untuk menjaga keseimbangan dan efisiensi gerak. Penelitian ini menyimpulkan bahwa analisis kecepatan vertikal tumit dapat berfungsi sebagai indikator yang berharga dalam memahami pola gerak dan mengidentifikasi potensi ketidakseimbangan atau gangguan gaya berjalan. Disarankan agar metode analisis gerak berbasis video diterapkan lebih luas dalam rehabilitasi, pelatihan atletik, dan pengembangan alat bantu mobilitas manusia.

Abstract

Accurate blood cell classification is crucial for diagnosing Acute Myeloid Leukemia (AML) but limited medical data poses challenges for traditional machine learning models. This study presents a Few-Shot Learning (FSL) framework utilizing a Prototypical Network architecture with a ResNet-34 backbone to classify AML blood cell types from microscopic images. In this study, we utilize datasets consisting of 15 morphologically distinct cell classes. A 15-way, 5-shot, 5-query episodic setup was adopted to simulate data-scarce conditions. Evaluation via 5-fold cross-validation yielded strong performance, with an average accuracy of 97.76%, precision of 98.78%, recall of 96.55%, and F1-score of 97.76%. FSL training times were consistent (4.22–4.26 minutes per fold), and t-SNE along with confusion matrices confirmed the model’s ability to distinguish similar cell types. To validate the approach, its performance was compared with a conventional supervised CNN using the same ResNet-34 backbone. The FSL model outperformed the CNN across all metrics such as accuracy (98.32% vs. 77.25%), precision (98.55% vs. 76.87%), recall (98.31% vs. 78.66%), and F1-score (98.33% vs. 75.26%), while also requiring far less training time (~4.24 min/fold vs. ~420 min total). These results highlight the promise of FSL based methods for accurate, efficient, and scalable hematologic diagnostics in data limited settings.

Abstract

Microneedles are a minimally invasive transdermal technology that has been widely explored in biomedical applications. Copper (Cu) is a promising material for microneedles due to its favorable mechanical properties and inherent antimicrobial effects. However, numerical studies on the structural performance of copper microneedles remain limited. This study aims to evaluate the mechanical response of solid copper microneedles using finite element analysis (FEA) in ANSYS Workbench. A 3D conical microneedle model with a height of 1000 µm was subjected to external pressures ranging from 400 to 1000 MPa. Four key parameters—total deformation, equivalent stress, maximum principal stress, and structural error—were assessed under two mesh densities (coarse and fine). Simulation results indicate that the fine mesh yields more accurate and stable stress and deformation distributions compared to the coarse mesh. Additionally, the fine mesh better captures peak stress concentrations, which are critical for evaluating microstructural failure. These findings underscore the importance of mesh selection in numerical simulations and provide a foundation for the preliminary design of copper-based microneedles for medical applications.
