Mengaktifkan Nomor XL Hangus Secara Daring/Online
Sekarang dalam masa pandemi ini, XL menyediakan layanan mengaktifkan nomor yang hangus secara daring tanpa harus datang ke kantor XL.
Langkah-langkah resmi dari XL dapat dilihat disini.
Ini adalah pengalaman saya mengaktifkan nomor XL yang hangus.
Setelah membuka e-form dan memilih layanan reaktivasi kartu, pihak XL meminta data nomor yang ingin diaktifkan:
Setelah itu, seperti yang sudah disebutkan pada petunjuk pada halaman resmi, e-form tadi meminta data diri, KTP dan Kartu Keluarga, sesuai dengan yang didaftarkan ketika nomor XL pertama kali diaktifkan. Dan jangan lupa nomor HP untuk video call. Pastikan nomor ini dapat melakukan video call karena pihak XL akan mengkonfirmasi pelanggan melalui video call, misalnya melalui whatsapp.
E-form tadi juga meminta 19 digit angka yang terletak dibelakang kartu XL yang ingin diaktifkan.
Selain itu, walaupun tidak tertera pada laman resmi, e-form juga akan meminta foto kartu XL tersebut, foto KTP dan juga foto diri beserta KTP.
Setelah semua data diunggah, dalam jangka waktu kalau tidak salah 48 jam, pihak XL akan menghubungi nomor yang dimasukkan untuk video call, dan akan segera melakukan video call jika pelanggan siap. Pihak XL akan meminta pelanggan menunjukkan KTP. Setelah itu, pihak XL akan mengaktifkan nomor dalam jangka waktu beberapa jam.
Setelah nomor aktif, pelanggan akan diminta mengisi pulsa, dan nomor XL akan siap digunakan kembali. Jika nomor masih tidak dapat digunakan, cobalah men-restart HP.

- Linguistic Features for Readability Assessment – Readability assessment aims to automatically classify text by the level appropriate for learning readers.
- Text as Environment: A Deep Reinforcement Learning Text Readability Assessment Model
- Learning to Predict Readability using Diverse Linguistic Features – In this paper we consider the problem of building a system to predict readability of natural-language documents.
- A Machine Learning Approach to Measurement of Text Readability for EFL Learners Using Various Linguistic Features
- Readability Assessment for Text Simplification – We describe a readability assessment approach to support the process of text simplification for poor literacy readers. Given an input text, the goal is to predict its readability level, which corresponds to the literacy level that is expected from the target reader: rudimentary, basic or advanced.
- Integrating LSA-based hierarchical conceptual space and machine learning methods for leveling the readability of domain-specific texts – Text readability assessment is a challenging interdisciplinary endeavor with rich practical implications. It has long drawn the attention of researchers internationally, and the readability models since developed
have been widely applied to various fields. Previous readability models have only made use of linguistic features employed for general text analysis and have not been sufficiently accurate when used to gauge domain-specific texts. - Deep Learning for Prominence Detection in Children’s Read Speech – A previous well-tuned random forest ensemble predictor is replaced by an RNN sequence classifier to exploit potential context dependency across the longer utterance. Further, deep learning is applied to obtain word-level features from low-level acoustic contours of fundamental frequency, intensity and spectral shape in an end-to-end fashion. Performance comparisons are presented across the different feature types and across different feature learning architectures for prominent word prediction to draw insights wherever possible.

Papers on Plant Image Detection
- Zhigang Dai, Bolun Cai, Yugeng Lin, Junying Chen, UP-DETR: Unsupervised Pre-training for Object Detection with Transformers – The model is pre-trained to detect these query patches from the original image. During the pre-training, we address two critical issues: multi-task learning and multi-query localization. (1) To trade-off multi-task learning of classification and localization in the pretext task, we freeze the CNN backbone and propose a patch feature reconstruction branch which is jointly optimized with patch detection. (2) To perform multi-query localization, we introduce UP-DETR from single-query patch and extend it to multi-query patches with object query shuffle and attention mask.
- Strawberry Detection Using a Heterogeneous Multi-Processor Platform.
This paper proposes using the You Only Look Once version 3 (YOLOv3) Convolutional Neural Network (CNN) in combination with utilising image processing techniques for the application of precision farming robots targeting strawberry detection, accelerated on a heterogeneous multiprocessor platform. The results show a performance acceleration by five times when implemented on a Field-Programmable Gate Array (FPGA) when compared with the same algorithm running on the processor side with an accuracy of 78.3\% over the test set comprised of 146 images. - Cream of the Crop: Distilling Prioritized Paths For One-Shot Neural Architecture Search – We introduce the concept of prioritized path, which refers to the architecture candidates exhibiting superior performance during training.
- Bag of Freebies for Training Object Detection Neural Networks [paperswithcode]
In this works, we explore training tweaks that apply to various models including Faster R-CNN and YOLOv3. These tweaks do not change the model architectures, therefore, the inference costs remain the same. Our empirical results demonstrate that, however, these freebies can improve up to 5% absolute precision compared to state-of-the-art baselines. - MMDetection: Open MMLab Detection Toolbox and Benchmark [github]

Standar Ventilasi Untuk Mengatasi Penularan COVID-19
Salah satu media penularan penyakit COVID-19 adalah melalui virus yang terlarut di udara sebagai aerosol.
Partikel virus yang besar (droplet) akan cepat jatuh dan menempel ke permukaan. Untuk mencegah penularan dari partikel ini ini dapat dilakukan hal berikut:
- mencuci tangan dengan sabun atau hand sanitizer
- tidak menyentuh wajah dengan tangan
- membunuh virus dengan cahaya ultraviolet,
- membunuh virus dengan desinfektan anti virus
Untuk mengurangi penularan melalui aerosol ini dapat menggunakan antara lain:
- masker wajah (face-mask)
- Penyaringan udara dengan saringan HEPA atau pembersih udara lainnya.
- penyinaran udara dengan cahaya ultra violet
- Ventilasi ruangan yang baik, supaya konsentrasi virus rendah
Standar ventilasi antara lain dikeluarkan oleh WHO (World Health Organization) dan CDC (Centers for Disease Control and Prevention).
Standar di Belgia [sumber]
- Level A: a CO2 concentration lower than 900 ppm (parts per million). Ventilation and/or air purification must therefore be provided at a rate of at least 40 m³ per hour per person.
- Level B: a CO2 concentration lower than 1,200 ppm or a ventilation flow of at least 25 m³ per hour per person.
