Logo Programming language

Dec 11, 2017Download as PPTX, PDF4 likes1,740 views

it's about an educational programming language which was designed for children learning through entertainment. The logo was created in 1967 at Bolt, Beranek and Newman, a Cambridge, Massachusetts research firm, by Wally Feurzeig, Cynthia Solomon, and Seymour Papert. Its intellectual roots are in artificial intelligence, mathematical logic, and developmental psychology.Logo's most-known feature is the turtle, an on-screen "cursor" that showed output from commands for movement and small retractable pen, together producing line graphics. There are 197 variations of the Logo Language and 130 existing implementations but broadly used and prevalent early implementation of Logo is the logo of Apple Inc. It was a primary influence on the Smalltalk programming language. For easily coding in Logo Language Stephane Norte & Fernando G. Lobo from UAlg informatics Laboratory at the University of Algarve, Portugal implemented an on-screen keyboard name Virtual Logo Keyboard. you can download the keyboard from http://w3.ualg.pt/~snorte/LogoKeyboard.htm

This document provides an introduction to basic computer concepts. It begins by outlining the goals of learning common computer terms, hardware, software and the desktop. It then defines a computer as a device that accepts input, processes data, stores and retrieves information, and provides output. Hardware is described as the physical components like the console, monitor, mouse, keyboard and printers. Software is defined as the set of instructions that directs the hardware. The desktop, icons, taskbar, start button and system tray are introduced as core elements of the graphical user interface. Basic mouse and keyboard functions are also reviewed.

Computer lesson 7 files & foldersallsaintstech

Files and folders are used to organize data on a computer. A file is a collection of data that is stored together and can be given a name, type, and location. Files are organized into folders, also called directories, to further group them together. The location and name of a file, including the file type extension, allows the computer to identify and retrieve the correct file when needed. Maintaining an organized folder structure with descriptive file names is important for efficiently finding and working with files on a computer.

Evaluation in hcisajid rao

The document discusses different methods for evaluating user interface designs, including expert evaluation techniques like heuristic evaluation and cognitive walkthroughs. It also covers user testing, which is considered more reliable than expert evaluation alone. Formative evaluation involves testing prototypes during development to identify issues, while summative evaluation assesses the final product. Both qualitative and quantitative methods are important to identify usability problems from the user's perspective.

Graphical User Interface Bivek Pakuwal

Graphical User Interface (GUI) is a visual way for users to interact with a computer program using graphical elements like windows, icons, menus, etc. rather than text-based commands. A GUI makes programs easier to use by presenting commands visually and allowing users to perform actions by clicking on screen elements rather than memorizing commands. Well-designed GUIs help users avoid complex text commands by providing intuitive graphical layouts and controls.

Ai EnvironmentJoy Protim

This document defines key properties of environments in reinforcement learning: 1) Environments can be deterministic, where the next state is completely determined by the current state and action, or episodic, where an agent's experience is divided into episodes with each episode consisting of perception and action. 2) Environments can be static, where they do not change while an agent deliberates, or dynamic if they can change during deliberation. They can also be discrete, with a limited number of percepts and actions, or continuous. 3) Environments are accessible if an agent's senses provide complete access to the environment state.

The Striatal-Cerebellar Pathways of Forming Beat- and Interval-based Temporal...Ana Lu��sa Pinho

This study explores the neural mechanisms underlying temporal predictions in beat-based and interval-based event sequences. Prior research has identified distinct roles for the dorsal striatum and cerebellum in the mediation of beat- and single-based predictions, respectively. Behavioral results from 39 participants show better performance in beat-based conditions, particularly in auditory tasks, suggesting a selective role of the basal ganglia in rhythmic processing. fMRI data from 31 participants reveal bilateral activation of the dorsal striatum and cerebellum during temporal sequence encoding, wherein the dorsal striatum exhibits a significantly stronger response in beat-based auditory tasks. Significant activation differences within these regions during the temporal encoding of the production task when compared to the other tasks highlight their selective role in timing-based predictions, with ongoing analyses exploring interactions with the cortex.

INVESTIGATING TARDIGRADES RESISTANCE AS A MODEL FOR LIFE IN EXTREME SPACE ENV...S��rgio Sacani

Introduction: Tardigrades, microscopic extremophiles renowned for their exceptional resilience to hostile environments, have emerged as a pivotal model for astrobiological research and the exploration of life's potential beyond Earth. These organisms exhibit remarkable adaptability, surviving extreme conditions such as temperatures ranging from -271��C to over 150��C, pressures exceeding 1,200 times atmospheric levels, desiccation, and intense ionizing radiation. Their unique biological traits pose fundamental questions about the molecular and cellular mechanisms underpinning such resilience. Central to this adaptability are specific proteins, such as Dsup (Damage Suppressor), which mitigates radiation-induced DNA damage by forming a protective shield around genetic material, reducing double-strand breaks and preserving genomic integrity.

Fading Light, Fierce Winds: JWST Snapshot of a Sub-Eddington Quasar at Cosmic...S��rgio Sacani

The majority of most luminous quasars during the epoch of reionization accrete near or above the Eddington limit, marking the vigorous growth of primitive supermassive black holes (SMBHs). However, their subsequent evolution and environmental impact remain poorly characterized. We present JWST/NIRSpec prism integral field unit observations of HSC J2239+0207, a low-luminosity quasar at z �� 6.25 likely in a late stage of mass assembly with an overmassive SMBH relative to its host galaxy. Using H�� and H�� broad emission lines, we estimate an SMBHmass MBH��3��108 Meand confirm its sub-Eddington accretion at ��Edd��0.4. Strong FeII emission and a proximity zone of typical size suggest a metal-rich, highly evolved system. In the far-UV, this quasar presents strong broad absorption line features, indicative of high-velocity winds (�� 104 km s?1). Meanwhile, minimal dust reddening is inferred from the quasar continuum and broad-line Balmer decrement, suggesting little dust along the polar direction. Most interestingly, we identify a gas companion ��5 kpc from the quasar with a high [O III]/H�� ratio (?10), likely representing outflowing gas blown away by active galactic nucleus (AGN) feedback. These results highlight HSC J2239+0207 as a likely fading quasar in transition, providing rare insights into SMBH evolution, AGN feedback, and AGN�Cgalaxy interactions in the early Universe.
