Program DownloadsThere are two kinds of program download links you will find on this site. If the program download looks like the following: Macroeconomia [repack] (Fast)Calculated via household surveys, this indicator lags behind economic activity. Falling unemployment typically indicates growth, but a falling rate can also occur if discouraged workers stop looking for jobs. By credibly anchoring long-term inflation expectations, central banks broke the self-fulfilling spiral of inflationary psychology. In this modern synthesis, the Phillips Curve became very flat in the short run: large movements in unemployment produced only small changes in inflation. This gave central banks more room to respond to recessions without fear of igniting inflation. However, the flattening of the curve also presented a new puzzle: if inflation no longer responds strongly to labor market slack, how should central banks fight deflationary recessions? The 2008 Global Financial Crisis tested this, as massive increases in unemployment failed to cause significant deflation, leading to fears of a "liquidity trap." Real GDP is adjusted for inflation, providing a true picture of growth. Nominal GDP uses current prices, which can be misleading during high inflation. Macroeconomia Governments and central banks use two main types of policy to manage these macroeconomic goals [19, 21]: Fiscal Policy: GDP is the total monetary value of all finished goods and services produced within a country's borders in a specific period. There are three ways to calculate it: Calculated via household surveys, this indicator lags behind Balanza de PagosRegistra todas las transacciones monetarias entre un paÃs y el resto del mundo, incluyendo exportaciones, importaciones y flujo de capitales. Objetivos de la MacroeconomÃa Quando lemos manchetes sobre inflação, ouvimos polÃticos debaterem o PIB ou vemos o Banco Central anunciar uma nova taxa de juros, estamos a navegar no mundo da . Embora possa parecer um conceito reservado para acadêmicos e especialistas em financeiras, a macroeconomia é, na verdade, a lente através da qual entendemos a saúde das nações e o bem-estar das sociedades. In this modern synthesis, the Phillips Curve became Focuses on aggregate demand as the primary engine of the economy [4, 18]. Monetarism: Required SoftwareThe downloadable programs for the projects (.rbt files) are written using the NXT-G programming system, which requires the LEGO MINDSTORMS NXT software to be installed in order to view them, edit them, or download them to the NXT brick. The program files cannot be used with RoboLab or any of the other NXT programming systems, not can they be viewed in standard text/graphics programs such as Microsoft Word or Adobe Reader.
If you have the LEGO MINDSTORMS NXT software installed, then a program file (.rbt) will automatically load into the NXT-G programming system when you open the file.
Errors Trying to Load or Compile a Downloaded ProgramAll of the program (.rbt) files on nxtprograms.com should load, compile and upload to your NXT through the standard NXT software without any additional software, if you have a suitable version of the NXT software installed, as explained in the Required Software section above. If you are getting "Error 5002" or "The program is broken. It may be missing required files", you are most likely trying to load an NXT 2.0 program into the NXT 1.X or other older version of the software. If you have the correct NXT software installed but you still get an error trying to load or compile a downloaded program such as "Invalid program file", or "Internal Compiler Error", it is possible that the file was not downloaded completely by your browser or was corrupted. The .rbt files are large and may fail to download completely in some cases. If this happens, try downloading the program again. Saving Changes to a ProgramIf you open a program file directly from the web site without saving it to your computer first, and you want to make changes and save them, you will need to save the file to a different location using the File -> Save As menu command. If you want to save the program to the default location for NXT program files, this location will be something like the following:
NXT 2.0 vs. NXT 1.X and Retail vs. Education Versions of the NXT SoftwareThe retail versions of the NXT kits (The original 8527 and the NXT 2.0 8547) come with the NXT software CD. If you lost your CD, you can contact LEGO Technical Support to get a replacement. The NXT 2.0 software can read and use all programs written for NXT 1.X, so if you have the NXT 2.0, you will also be able to load the programs from the NXT 1.X projects and possibly adapt them a similar robot of your own design. The NXT 1.X software cannot in general use programs written for NXT 2.0. You will usually be able to load them and examine them, but some blocks may not display properly. Some very simple NXT 2.0 programs can be downloaded to a 1.X NXT, but in general you will not be able to use them. The NXT software for the Education version of the NXT (9797) is sold separately here at LEGO Education and contains different help material and building instructions from the retail version of the software, although either version of the software can be used to write programs for either NXT kit.  For the NXT 2.0 projects on this site, the LEGO Education NXT-G 2.1 software is required to use any programs that use the color sensor or the Pack-and-Go (.rbtx) format, otherwise the LEGO Education NXT-G 2.0 software will work with most 2.0 programs. |
