Doelstelling van dit college is een introductie te geven in de theorie van de Thermodynamica, een van de fundamentele werktuigbouwkunde vakken. De Thermodynamica behandelt energie vraagstukken en relaties tussen de eigenschappen van materialen. In dit college wordt voor een ingenieurs aanpak van de Thermodynamica gekozen: onderwerp van studie zijn systemen en hun interactie met de omgeving. Naast gesloten systemen krijgen open systemen veel aandacht. Thermodynamica wordt, in combinatie met stromingsleer en warmte- en stofoverdracht, ingezet om bijvoorbeeld automotoren, turbines, compressoren, pompen, elektriciteit opwekkinginstallaties, cryogenische-, koel- en klimaat-installaties en duurzame energieconversie installaties te analyseren en ontwerpen. De beginselen van de Thermodynamica maken het mogelijk om de ontwerpen van energie gerelateerde werktuigbouwkundige apparaten en systemen te optimaliseren voor het betreffende doel.

De thermodynamische relaties voor compressibele stoffen en de fasendiagrammen voor pure stoffen worden behandeld. Enkele voorbeelden van toestandsvergelijkingen worden behandeld (de viriaal vergelijking, vergelijkingen met twee constanten en vergelijkingen met meerdere constanten). De grootheden Helmholtz energie en Gibbs energie worden geintroduceerd. De Gibbs vergelijking is de basis om tot een beschrijving van evenwichten (van mengsels) te komen. De condities van evenwicht van pure componenten en van mengsels wordt afgeleidt. Uitgaande van de totale differentialen worden partiele afgeleide uit gedrukt in termen van thermodynamische grootheiden. Voor de berekening van processen, zo als compressie, expansie enz worden uitdrukkingen afgeleid voor delta h, delta s en delta u (waarbij delta voor de deviatie="departure" van ideaal gas gedrag staat). Het wordt getoond hoe deze uitdrukkingen (of dimensieloze diagrammen van deze grootheden) voor de berekening van processen gebruikt kunnen worden. Ook wordt de grootheid exergie gepresenteerd, een grootheid die gebaseerd is op de tweede hoofdwet van de thermodynamica, tezamen met enkele nuttige grootheden en hulpmiddelen voor het uitvoeren van exergie analyses (exergie verlies, exergie rendementen, waardediagram). In dit college wordt de definitie van exergie beperkt tot de thermo-mechanische exergie. Het principe van het stoomturbine kringproces wordt getoond en mogelijkheden voor de optimalisatie van dit kringproces worden besproken, zoals de keuze van stoomdruk en -temperatuur en de toepassing van stoomoververhitting en -herverhitting.

The objective is to get insight and practice in the design and use of mathematical models for the estimation of transport demand in the framework of major strategic transportation planning. The course consists of a number of lectures and several exercises in OmniTRANS.

Tá Falado includes 46 podcast lessons on the pronunciation and grammar of Portuguese, specifically designed to help those who already speak Spanish. The lessons are built around Portuguese dialogs that are repeated in Spanish, providing a direct comparison of the two languages. All lessons include downloadable PDF files with the transcripts and notes, mp3 audio files, and blog discussions. Additionally all of the dialogs present cultural scenarios that illustrate differences between North American and Brazilian culture.

This course is the first in the introductory surveys of U.S. History. After exploring North America before the arrival of Europeans, students will study the early interactions of Europeans with indigenous peoples and, as the course progresses, study the history of peoples in the area now defined by the United States' borders. Those who would like to pursue their study of American history will also want to take Hist 147 (U.S. History II) and Hist 148 (U.S. History III).Login: guest_oclPassword: ocl

Welcome to History 147, the second in the introductory surveys of U.S. history. We begin in that decade when the United States in three years (1845-48) grew by 50 percent. Through the Civil War to the 20th century, we explore how different people experienced the transformation of the country into an industrial nation and emerging world power. Those who would like to pursue their study of American history will want to take Hist 146 (U.S. History I) and Hist 148 (U.S. History III).

This course is the third in the introductory surveys of U.S. history. The course surveys the significant forces and people that have shaped American civilization from the Progressive Era to the present. This course starts at the beginning of the 20th century and explores how different people, including you, participated in the nation's transformation through that century until today. Those who would like to pursue their study of American history may wish to take Hist 146 (US History I) and Hist 147 (US History II).Login: guest_oclPassword: ocl

The lectures will discuss characteristics of urban water flows, hydraulics, hydrology and how to apply knowledge of these phenomena to the design and analysis of urban water systems. Integration of various scientific disciplines and technological and practical approaches is a central theme in this course.

Students will design an urban drainage system for a real case in the Netherlands or abroad using the Rational Method. They will use this design as input for a hydrodynamic computer model and perform model calculations for various conditions to check the performance of the designed system and improve where needed. They will prepare a written report of their data, design choices and results and present main results in a plenary session that concludes the lecture series.

This course introduces basic welding and cutting. Emphasis is placed on beads applied with gases, mild steel fillers, and electrodes and the capillary action of solder. Upon completion, students should be able to set up welding and oxy-fuel equipment and perform welding, brazing, and soldering processes. 

This course is meant to be an introduction to MIG welding. It was created in conjunction with the AWESM grant consortium led by Forsyth Tech. The material has been reviewed and acknowledged by the eight colleges within the program.The PDF includes the course layout, embedded readings, and links to video content.The PDF includes the course layout, embedded readings, and links to video content.
