Differentiation
Differentiation allows us to find the rate of change of one variable with respect to another. It was developed by Isaac Newton to improve understanding of how celestial bodies move in relation to each other and address navigation problems at sea. Differentiation and integration can help solve real-world problems involving tangents, normals, curvilinear motion, related rates, curve sketching, max/min values, and radius of curvature. Differentiation has many applications in everyday life such as determining object position, stock market calculations, and measuring changes in mechanical properties.

Accessibility is a complex property of information, a composite of several different indicators that measure the ease with which one can get to and work with information from another source. These different indicators of accessibility scale differently with the size and scope of information. As the datasets get bigger, some indicators remain constant, some scale linearly, while others may scale in a more accelerated manner. At the University of Wisconsin Carbon Modeling group, we are building a very large, spatially accessible U.S. national climate dataset for ecosystem process modeling that is bringing up unique challenges and lessons for accessibility in the multi-Terabyte scale datasets. This paper describes the problem, and the information accessibility challenges and lessons learned while putting together its solution.
Virtualbuildspacepowerpoint
VirtualBuildSpace is a proposed online game that would raise money for space exploration projects while inspiring and educating players. It would allow players to complete simulated tasks related to operating equipment on the International Space Station, conducting experiments in zero gravity, planning Mars missions, and more. The game aims to get more countries and individuals invested in funding space initiatives, which currently receive a small fraction of national budgets. It also hopes to introduce more children to STEM fields by making space topics accessible and fun through gameplay.
Esip 2019 Winter Plenary - Dan Pilone - From Baseline Science Instruments to ...
Element 84 has been working in the ballooning CubeSat space and recognizes the massive amount of data flowing in from CubeSats and that the biggest use of CubeSats are commercial companies and universities. Previously, only big government agencies could afford satellite remote sensing instruments, then big companies (e.g. DigitalGlobe), and now CubeSats have commoditized satellite data collection such that universities and smaller companies are able to launch their own missions. Each of these constellations are capable of streaming down massive amounts of data, providing nearly constant Earth observation and rapid revisit rates. This talk discusses CubeSats 101, our commercial data pipeline infrastructure (CubeSatData.com) that commoditized what used to be the exclusively in the realm of NASA, NOAA, and companies like DG, and the implications of the increased accessibility of SmallSat data collection.

The document discusses the impressive engineering feats required for NASA and ESA space missions to land on a comet and flyby Pluto. It summarizes that the spacecraft had to reach escape velocity from Earth in just minutes using rocket boosters and gravitational slingshots from planets to reach speeds over 32,500 mph. It took the Pluto mission 9.5 years to travel billions of miles, and missing the launch date by even one day would have caused it to miss Pluto entirely. The document argues these successful, complex missions demonstrate principles from Lean Six Sigma such as process mapping, risk analysis, and optimization that could be applied to other domains.

Space X
SpaceX's vision involves three phases: 1) Figuring out how to put things in space, 2) Reducing the cost of space travel through ongoing delivery services, 3) Bringing the cost of sending a person to Mars under $500,000. SpaceX aims to safely and reliably deliver payloads to orbit at much lower prices than competitors through transparent pricing, milestone-based development, and carrying risk themselves. They have innovated through reusable rockets using a single engine type, and mass production through vertical integration and newer manufacturing technologies like 3D printing. Key milestones include NASA contracts, crewed flights to ISS, and successful rocket landings.

The Alpha CubeSat project aims to launch a 6U CubeSat into deep space to demonstrate new satellite technologies and conduct experiments. It will travel as far as 4 million km from Earth before entering lunar orbit to study the Moon's surface. The CubeSat aims to win the NASA Cube Quest Challenge by demonstrating advanced operations in deep space using minimal energy trajectories. It will test new satellite instruments and orbital maneuvers. The goal is to establish affordable and regular access to space by taking advantage of launches from the International Space Station and rideshares with other rockets.
Space internet and starlink
Starlink is a satellite internet constellation being constructed by SpaceX providing satellite Internet access started in 2015.
Astronomy Research Via The Internet
This document discusses how astronomy research can be conducted via the internet without the need for expensive local observatories or instrumentation. Some key points made include:
1) Astronomy research can be done remotely using data from space telescopes and other large ground-based facilities available online. This makes research possible from any location with an internet connection.
2) Access to astronomical data archives, journals, software, and opportunities for remote observing and collaborations allow cutting-edge research to be done with only a computer and internet access.
3) The declining costs of computers, internet connectivity, and online data storage have made internet-based astronomy research a low-cost option for developing countries compared to establishing local observatories.
Low Earth Orbit Satellite (LEO)
The document discusses different types of orbits used by satellites, including low Earth orbit (LEO), medium Earth orbit (MEO), and geosynchronous orbit (GEO). It then focuses on using LEO satellites to provide affordable, high-speed internet access globally. Several companies are working on large LEO satellite constellations, including SpaceX, OneWeb, Amazon, and Kepler Communications. These companies face hurdles such as meeting service expectations, ensuring satellite reliability, managing space debris, addressing economic uncertainties, and navigating regulation.
Saltman
The Commercial Spaceflight Federation (CSF) is an industry association working to enable commercial human spaceflight. Its mission is to promote the development of commercial human spaceflight and pursue safety. Michael Lopez-Alegria was recently hired as CSF's President. The document outlines CSF's 45 members and recent activities. It also summarizes NASA's partnerships with commercial companies through programs like COTS, CCDev, and space technology development to make exploration more affordable and efficient.
FDL 2017 3D Shape Modeling
The document discusses improving the process of generating 3D shape models of asteroids from radar observations. It proposes several solutions: a) Pre-processing radar data faster, b) Determining asteroid spin axes faster using Bayesian optimization, c) Improving the generation of training data using non-convex synthetic shapes, and d) Advancing the neural network approach using techniques like variational autoencoders to represent asteroids in a compact latent space. The overall aim is to streamline the modeling pipeline to analyze radar observations of near-Earth asteroids faster than they are acquired.
Internship Poster Session Lorenz Mosser _Lorenz Edit2
The document discusses a proposed technology demonstration mission to test electric sail (E-sail) propulsion. E-sails use charged tethers and solar wind to propel spacecraft without propellant. The mission would deploy 16.5 km of tether from a 12U CubeSat at Earth-Moon L1 point. Previous tether missions often failed during deployment, which is identified as the main risk. Three deployment schemes are considered, with a "barbell" design selected for analysis to assess thrusting with charged 16.5 km tethers and steering capabilities. The goal is to advance E-sail technology needed for future missions like faster travel to the Heliopause.
Use of Micro Satellites for Global Connectivity, High Speed Transmission & Da...
This document proposes using micro satellites in very low Earth orbit to create a global connectivity network providing high-speed transmission and data analysis capabilities. The network would consist of interconnected cube satellites drifting in a planned orbit. Using high-efficiency thrusters and quantum data transmission, the network could provide low-latency connectivity down to 20-30 milliseconds globally. In addition to connectivity, the constant Earth observation capabilities could allow for weather monitoring, disaster alerts and scientific data analysis. The goals are to provide high-speed internet access globally, including rural areas, as well as accurate weather data and monitoring of natural disasters.
IJSRED-V2I5P46
This document proposes using a constellation of interconnected cube satellites in very low Earth orbit to provide global connectivity, high-speed data transmission, and data analysis. The satellites would drift relative to each other while maintaining connections to provide continuous coverage. Later phases would include smaller picosatellites for denser coverage. Data would be transmitted using quantum packets for high speeds and security. The system aims to provide internet access worldwide and enable applications like weather monitoring and disaster alerting.
Will The International Space Station de-orbit_.pdf
The International Space Station is revealing how old it very well may be. It’s more seasoned than 33% of the populace, north of over two billion individuals who have never known a period without people in circle.
Pieces and bits of it continue to turn out badly, most as of late the EVA spacesuits; Russia might possibly be going to bail; and it’s more Red Dwarf than the Enterprise with regards to space microbes.
You thought it was troublesome getting a cleaner to come to your condo in the city? According to one perspective, it’s exhausted, super-costly to run, and isn’t contributing a lot to space investigation any more, and is absorbing substantially a lot of room designers’ mind time.
Does that apply to any inheritance innovation you knew about? IT heritages don’t make cool recordings of the Earth from space or space travelers tumbling in microgravity, so they miss out vigorously to the International Space Station on the advertising front. They won’t be consuming 15% of a $22 billion spending plan by the same token
¿Por qué debemos seguir trabajando en álgebra lineal?
"El álgebra lineal es una herramienta fundamental en muchos campos de la ciencia y la tecnología. Es particularmente importante en la física, la ingeniería, la informática y la estadística. La capacidad de manipular eficientemente grandes cantidades de datos y matrices complejas es esencial en estas áreas para la resolución de problemas y la toma de decisiones.
A priori, puede dar la sensación de que estamos muy lejos del uso del álgebra lineal en nuestro día a día. Sin embargo, algunas técnicas como la descomposición en valores singulares y la regresión lineal para entrenar modelos y hacer predicciones precisas están detrás de la inteligencia artificial y el aprendizaje automático. ¿Te suena ChatGPT? Puede no parecerlo, pero el álgebra lineal también está detrás en algunos de sus procesos. Por este motivo, debemos seguir trabajando en este campo, ya que su importancia seguirá creciendo a medida que se generen y analicen grandes cantidades de datos en el mundo actual.

TECNOPOLÍTICA Y ACTIVISMO DE DATOS: EL MAPEO COMO FORMA DE RESILIENCIA ANTE L...Facultad de Informática UCM
La pandemia de COVID-19 ha supuesto una proliferación de mapas y contramapas. Por ello, organizaciones de la sociedad civil y movimientos sociales han generado sus propias interpretaciones y representaciones de los datos sobre la crisis. Estos también han contribuido a visibilizar aspectos, sujetos y temas que han sido desatendidos o infrarrepresentados en las visualizaciones hegemónicas y dominantes. En este contexto, la presente ponencia se centra en el análisis de los imaginarios sociales relacionados con la elaboración de mapas durante la pandemia. Es decir, trata de indagar en la importancia de los mapas para el activismo digital, las potencialidades que se extraen de esta tecnología y los valores asociados a las visualizaciones creadas con ellos. El objetivo último es reflexionar sobre la vía emergente del activismo de datos, así como sobre la intersección entre los imaginarios sociales y la geografía digital.More Related Content

Internship Poster Session Lorenz Mosser _Lorenz Edit2
The document discusses a proposed technology demonstration mission to test electric sail (E-sail) propulsion. E-sails use charged tethers and solar wind to propel spacecraft without propellant. The mission would deploy 16.5 km of tether from a 12U CubeSat at Earth-Moon L1 point. Previous tether missions often failed during deployment, which is identified as the main risk. Three deployment schemes are considered, with a "barbell" design selected for analysis to assess thrusting with charged 16.5 km tethers and steering capabilities. The goal is to advance E-sail technology needed for future missions like faster travel to the Heliopause.

This document proposes using micro satellites in very low Earth orbit to create a global connectivity network providing high-speed transmission and data analysis capabilities. The network would consist of interconnected cube satellites drifting in a planned orbit. Using high-efficiency thrusters and quantum data transmission, the network could provide low-latency connectivity down to 20-30 milliseconds globally. In addition to connectivity, the constant Earth observation capabilities could allow for weather monitoring, disaster alerts and scientific data analysis. The goals are to provide high-speed internet access globally, including rural areas, as well as accurate weather data and monitoring of natural disasters.

Data would be transmitted using quantum packets for high speeds and security. The system aims to provide internet access worldwide and enable applications like weather monitoring and disaster alerting.
Will The International Space Station de-orbit_.pdf
The International Space Station is revealing how old it very well may be. It’s more seasoned than 33% of the populace, north of over two billion individuals who have never known a period without people in circle.
Pieces and bits of it continue to turn out badly, most as of late the EVA spacesuits; Russia might possibly be going to bail; and it’s more Red Dwarf than the Enterprise with regards to space microbes.
You thought it was troublesome getting a cleaner to come to your condo in the city? According to one perspective, it’s exhausted, super-costly to run, and isn’t contributing a lot to space investigation any more, and is absorbing substantially a lot of room designers’ mind time.
Does that apply to any inheritance innovation you knew about? IT heritages don’t make cool recordings of the Earth from space or space travelers tumbling in microgravity, so they miss out vigorously to the International Space Station on the advertising front. They won’t be consuming 15% of a $22 billion spending plan by the same token

¿Por qué debemos seguir trabajando en álgebra lineal?
"El álgebra lineal es una herramienta fundamental en muchos campos de la ciencia y la tecnología. Es particularmente importante en la física, la ingeniería, la informática y la estadística. La capacidad de manipular eficientemente grandes cantidades de datos y matrices complejas es esencial en estas áreas para la resolución de problemas y la toma de decisiones.
A priori, puede dar la sensación de que estamos muy lejos del uso del álgebra lineal en nuestro día a día. Sin embargo, algunas técnicas como la descomposición en valores singulares y la regresión lineal para entrenar modelos y hacer predicciones precisas están detrás de la inteligencia artificial y el aprendizaje automático. ¿Te suena ChatGPT? Puede no parecerlo, pero el álgebra lineal también está detrás en algunos de sus procesos. Por este motivo, debemos seguir trabajando en este campo, ya que su importancia seguirá creciendo a medida que se generen y analicen grandes cantidades de datos en el mundo actual.

La pandemia de COVID-19 ha supuesto una proliferación de mapas y contramapas. Por ello, organizaciones de la sociedad civil y movimientos sociales han generado sus propias interpretaciones y representaciones de los datos sobre la crisis. Estos también han contribuido a visibilizar aspectos, sujetos y temas que han sido desatendidos o infrarrepresentados en las visualizaciones hegemónicas y dominantes. En este contexto, la presente ponencia se centra en el análisis de los imaginarios sociales relacionados con la elaboración de mapas durante la pandemia. Es decir, trata de indagar en la importancia de los mapas para el activismo digital, las potencialidades que se extraen de esta tecnología y los valores asociados a las visualizaciones creadas con ellos. El objetivo último es reflexionar sobre la vía emergente del activismo de datos, así como sobre la intersección entre los imaginarios sociales y la geografía digital.DRAC: Designing RISC-V-based Accelerators for next generation Computers

Then, it will go through some of the R+D on-going activities that the group is involved with, hand in hand with universities and/or companies. One of the major ones is related to the European rad-hard FPGAs that have been partially founded by ESA for several years and that will be playing a major role in the sector in the upcoming years. It´s also worth talking about the RTL soft IPs that are currently under development and that will allow us to keep on providing the European ecosystem with some key capabilities. The latter will be an overview of RISC-V space hardened on-going activities that might be replacing the current SPARC based processors available for our missions.
Tendencias en el diseño de procesadores con arquitectura Arm
El objetivo de esta charla es presentar las últimas novedades incorporadas en la arquitectura ARM y describir las tendencias en la microarquitectura de los procesadores con arquitectura ARM. ARM es una empresa relativamente pequeña en comparación con otros gigantes del sector tecnológico. Sin embargo, la amplia implantación de su arquitectura, siendo ampliamente dominante en algunos sectores, y sus microarquitecturas, hacen que la tecnología ARM ocupe un lugar central en el desarrollo tecnológico del mundo actual.

Formalizing Mathematics in Lean
"Formal verification has been used by computer scientists for decades to prevent
software bugs. However, with a few exceptions, it has not been used by researchers
working in most areas of mathematics (geometry, algebra, analysis, etc.). In this
talk, we will discuss how this has changed in the past few years, and the possible
implications to the future of mathematical research, teaching and communication.
We will focus on the theorem prover Lean and its mathematical library
mathlib, since this is currently the system most widely used by mathematicians.
Lean is a functional programming language and interactive theorem prover based
on dependent type theory, with proof irrelevance and non-cumulative universes.
The mathlib library, open-source and designed as a basis for research level
mathematics, is one of the largest collections of formalized mathematics. It allows
classical reasoning, uses large- and small-scale automation, and is characterized
by its decentralized nature with over 200 contributors, including both computer
scientists and mathematicians."
Introduction to Quantum Computing and Quantum Service Oriented Computing
"Part of the research community thinks that it is still early to tackle the development of quantum software engineering techniques. The reason is that how the quantum computers of the future will look like is still unknown. However, there are some facts that we can affirm today: 1) quantum and classical computers will coexist, each dedicated to the tasks at which they are most efficient. 2) quantum computers will be part of the cloud infrastructure and will be accessible through the Internet. 3) complex software systems will be made up of smaller pieces that will collaborate with each other. 4) some of those pieces will be quantum, therefore the systems of the future will be hybrid. 5) the coexistence and interaction between the components of said hybrid systems will be supported by service composition: quantum services.
This talk analyzes the challenges that the integration of quantum services poses to Service Oriented Computing."
Computer Design Concepts for Machine Learning
In this talk, after a brief overview of AI concepts in particular Machine Learning (ML) techniques, some of the well-known computer design concepts for high performance and power efficiency are presented. Subsequently, those techniques that have had a promising impact for computing ML algorithms are discussed. Deep learning has emerged as a game changer for many applications in various fields of engineering and medical sciences. Although the primary computation function is matrix vector multiplication, many competing efficient implementations of this primary function have been proposed and put into practice. This talk will review and compare some of those techniques that are used for ML computer design.

Design Automation Approaches for Real-Time Edge Computing for Science Applic...Facultad de Informática UCM
Many emerging applications require methods tailored towards high-speed data acquisition and filtering of streaming data followed by offline event reconstruction and analysis. In this case, the main objective is to relieve the immense pressure on the storage and communication resources within the experimental infrastructure. In other applications, ultra low latency real time analysis is required for autonomous experimental systems and anomaly detection in acquired scientific data in the absence of any prior data model for unknown events. At these data rates, traditional computing approaches cannot carry out even cursory analyses in a time frame necessary to guide experimentation. In this talk, Prof. Ogrenci will present some examples of AI hardware architectures. She will discuss the concept of co-design, which makes the unique needs of an application domain transparent to the hardware design process and present examples from three applications: (1) An in-pixel AI chip built using the HLS methodology; (2) A radiation hardened ASIC chip for quantum systems; (3) An FPGA-based edge computing controller for real-time control of a High Energy Physics experiment.Estrategias de navegación para robótica móvil de campo: caso de estudio proye...

En esta conferencia se presentará una revisión del concepto de autonomía para robots móviles de campo y la identificación de desafíos para lograr un verdadero sistema autónomo, además de sugerir posibles direcciones de investigación. Los sistemas robóticos inteligentes, por lo general, obtienen conocimiento de sus funciones y del entorno de trabajo en etapa de diseño y desarrollo. Este enfoque no siempre es eficiente, especialmente en entornos semiestructurados y complejos como puede ser el campo de cultivo. Un sistema robótico verdaderamente autónomo debería desarrollar habilidades que le permitan tener éxito en tales entornos sin la necesidad de tener a-priori un conocimiento ontológico del área de trabajo y la definición de un conjunto de tareas o comportamientos predefinidos. Por lo que en esta conferencia se presentarán posibles estrategias basadas en Inteligencia Artificial que permitan perfeccionar las capacidades de navegación de robots móviles y que sean capaces de ofrecer un nivel de autonomía lo suficientemente elevado para poder ejecutar todas las tareas dentro de una misión casa-a-casa (home-to-home).Fault-tolerance Quantum computation and Quantum Error Correction
Quantum computing has become a noteworthy topic in academia and industry. The multinational companies in the world have been obtaining impressive advances in all areas of quantum technology during the last two decades. These companies try to construct real quantum computers in order to exploit their theoretical preferences over today’s classical computers in practical applications. However, they are challenging to build a full-scale quantum computer because of their increased susceptibility to errors due to decoherence and other quantum noise. Therefore, quantum error correction (QEC) and fault-tolerance protocol will be essential for running quantum algorithms on large-scale quantum computers.
The overall effect of noise is modeled in terms of a set of Pauli operators and the identity acting on the physical qubits (bit flip, phase flip and a combination of bit and phase flips). In addition to Pauli errors, there is another error named leakage errors that occur when a qubit leaves the defined computational subspace. As the location of leakage errors is unknown, these can damage even more the quantum computations. Thus, this talk will briefly provide quantum error models.
Cómo construir un chatbot inteligente sin morir en el intento
Los chatbots son un elemento clave en la transformación digital de nuestra sociedad. Están por todas partes: eCommerce, salud digital, asistencia a clientes, turismo,... Pero si habéis usado alguno, probablemente os habrá decepcionado. Lo confieso, la mayoría de los chatbots que existen son muy malos. Y es que no es nada fácil hacer un chatbot que sea realmente útil e inteligente. Un chatbot combina toda la complejidad de la ingeniería de software con la del procesamiento de lenguaje natural. Pensad que muchos chatbots hay que desplegarlos en varios canales (web, telegram, slack,...) y a menudo tienen que utilizar APIs y servicios externos, acceder a bases de datos internas o integrar modelos de lenguaje preentrenados (por ej. detectores de toxicidad), etc. Y el problema no es sólo crear el bot, si no también probarlo y evolucionarlo. En esta charla veremos los mayores desafíos a los que hay que enfrentarse cuando nos encargan un proyecto de desarrollo que incluye un chatbot y qué técnicas y estrategias podemos ir aplicando en función de las necesidades del proyecto, para conseguir, esta vez sí un chatbot que sepa de lo que habla.
Automatic generation of hardware memory architectures for HPC
Many HPC applications are massively parallel and can benefit from the spatial parallelism offered by reconfigurable logic. While modern memory technologies can offer high bandwidth, designers must craft advanced communication and memory architectures for efficient data movement and on-chip storage. Addressing these challenges requires to combine compiler optimizations, high-level synthesis, and hardware design.
In this talk, I will present challenges, solutions, and trends for generating massively parallel accelerators on FPGA for high-performance computing. These architectures can provide performance comparable to software implementations on high-end processors, and much higher energy efficiency thanks to logic customization.
Type and proof structures for concurrency
The main challenge of concurrent software verification has always been in achieving modularity, i.e., the ability to divide and conquer the correctness proofs with the goal of scaling the verification effort. Types are a formal method well-known for its ability to modularize programs, and in the case of dependent types, the ability to modularize and scale complex mathematical proofs.
In this talk I will present our recent work towards reconciling dependent types with shared memory concurrency, with the goal of achieving modular proofs for the latter. Applying the type-theoretic paradigm to concurrency has lead us to view separation logic as a type theory of state, and has motivated novel abstractions for expressing concurrency proofs based on the algebraic structure of a resource and on structure-preserving functions (i.e., morphisms) between resources.

Hardware/software security contracts: Principled foundations for building sec...Facultad de Informática UCM
Microarchitectural attacks, such as Spectre and Meltdown, are a class of
security threats that affect almost all modern processors. These attacks exploit the side-effects resulting from processor optimizations to leak sensitive information and compromise a system’s security.
Over the years, a large number of hardware and software mechanisms for
preventing microarchitectural leaks have been proposed. Intuitively, more
defensive mechanisms are less efficient, while more permissive mechanisms may offer more performance but require more defensive programming. Unfortunately, there are no
hardware-software contracts that would turn this intuition into a basis for
principled co-design.
In this talk, we present a framework for specifying hardware/software security
contracts, an abstraction that captures a processor’s security guarantees in a
simple, mechanism-independent manner by specifying which program executions a
microarchitectural attacker can distinguish.Jose carlossancho slidesLa seguridad en el desarrollo de software implementad...

La aparición de vulnerabilidades por la falta de controles de seguridad es una de las causas por las que se demandan nuevos marcos de trabajo que produzcan software seguro de forma predeterminada. En la conferencia se abordará cómo transformar el proceso de desarrollo de software dando la importancia que merece la seguridad desde el inicio del ciclo de vida. Para ello se propone un nuevo modelo de desarrollo – modelo Viewnext-UEx – que incorpora prácticas de seguridad de forma preventiva y sistemática en todas las fases del proceso de ciclo de vida del software. El propósito de este nuevo modelo es anticipar la detección de vulnerabilidades aplicando la seguridad desde las fases más tempranas, a la vez que se optimizan los procesos de construcción del software. Se exponen los resultados de un escenario preventivo, tras la aplicación del modelo Viewnext-UEx, frente al escenario reactivo tradicional de aplicar la seguridad a partir de la fase de testing.Do you trust your artificial intelligence system?

Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
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

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
