"JavaScript in 2016" by Eduard Tomàs
Some years ago in a far far away company, Brendan Eich created JavaScript. A lot of things happened since then. Times changed, the web grown, the language itself was updated, and we as a developers need to adapt too. Last year the last standard of the language arose: ECMAScript 2015 is here, and has some new and interesting features. In this talk we will show the most relevant ones, and also we will introduce some interesting patterns that you can use in JavaScript: you'll learn how to master the language and made JavaScript your best ally to conquest the world!
The document summarizes new features in Ruby 2, including lazy enumerators that allow infinite enumerations to be cut off, the Module#prepend method that puts modules before classes in the method lookup path, String methods like #bytes now returning arrays instead of enumerators, keyword arguments that allow default parameters, and various other minor changes.
This document discusses non-local neural networks, which use non-local operations to capture long-range dependencies in data. The non-local operation computes the response at a position as a weighted sum of the features at all positions. Adding non-local blocks to existing models leads to improved performance on video classification tasks without increasing parameters or FLOPs significantly. Experimental results show that non-local operations are complementary to 3D convolutions and help models better capture long-range dependencies in space and time.

precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical

Ion propulsion technology is proven to be feasible in the earth’s atmosphere. The study presented in this article shows the design of EHD thrusters and power supply for ion propulsion drones along with performance optimization of high-voltage power supply for endurance in earth’s atmosphere.
An improved modulation technique suitable for a three level flying capacitor ...IJECEIAES
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.
