14. ETAPAS DO MÉTODO CIENTÍFICO

from Prof. Isaac Siebra · host Isaac Siebra Ferreira

ETAPAS DO MÉTODO CIENTÍFICO Em uma visão simplificada, o procedimento adotado pelos cientistas para investigar a natureza geralmente segue os seguintes passos lógicos: 1. Proposição de uma pergunta. 2. Formulação de uma hipótese. 3. Levantamento de deduções a partir da hipótese. 4. Teste das deduções, por meio de novas observações ou de experimentos. 5. Conclusões sobre a validade ou não da hipótese. Exemplo: A partir da observação de que goiabas podem ter “bichos” e que moscas podem ser vistas pousadas sobre as goiabas r, tendo por base a teoria de que todo ser vivo surge pela reprodução de outros seres vivos, um cientistas elabora uma hipótese para explicar um fato: os “bichos” da goiaba devem ser larvas de moscas. Com base nessa hipótese, são feitas deduções; por exemplo, se as goiabas forem protegidas com saquinhos de papel, nelas não se desenvolverão “bichos”. As hipóteses podem ser refutadas ou não, por meio de experimentos ou de novas observações.

Ringvorlesung - Practical Data Engineering (WT 2019/20) - tele-TASK Prof. Dr. Tilmann Rabl The Lecture Series on Practical Data Engineering will feature presentations by distinguished speakers from industry and academia on the topic of data engineering. We will cover topics on the application of data engineering in industrial setups as well as system level advancements in data engineering research. Is Jesus Lord of your life Pastor Isaac De Los Santos What Does It Mean to Say That Jesus Christ is Lord? For Jesus to be Lord of your life means that He is the ruler, the boss, the master of your whole life. Hardware-Conscious Data Processing (ST 2023) - tele-TASK Prof. Dr. Tilmann Rabl Hardware development continuously advances, with different technologies improving at different pace. While the amount of transistors in a CPU package are growing, the single core performance is stagnating due to physical limitations. These trends require changes in data processing to keep database management systems efficient. In this lecture, we will take a look at current computer architectures and accelerator technologies and how they can be used for efficient data processing. We will cover CPU and memory architecture; the storage hierarchy; modern memory technolgoies, such as NVM and NVMe; fast interconnects, such as Infiniband, RDMA, and NVLink; and accelerators, such as GPUs and FPGAs. The course has a significant practical part, where the students learn to implement data structures and algorithms tailored to hardware concious data processing.
