Electromagnetics Volume 1 by Steven W. Ellingson is a 225-page, peer-reviewed open educational resource intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wage equations for voltage and current.

This course covers the major topics of mechanics, including momentum and energy conservation, kinematics, Newton‰ŰŞs laws and equilibrium. The major emphasis is to develop critical analysis, problem solving and scientific reasoning skills by considering numerous different systems and interactions, solving problems and discussion. It uses a systematic approach based on modeling systems by application of basic physics principles, making assumptions, utilizing multiple representations (not just mathematical) in order to become proficient at problem solving. Lab work is required and is designed to help students develop a questioning approach to physical situations, distinguishing the significant behaviors from the less significant behaviors of a system under study.Login: guest_oclPassword: ocl

Labs in this book supplement the information gained in lecture, as well as providing some perspective and experience with hands-on applications of ideas in pest management. The labs are presented in week-by-week order, so the pre-labs and reading for week 1 are labeled “Pre-Lab 1” and “Week 1 Reading”.

Pre-Labs are assignments to be done before lab meets, and will be due at the beginning of Lab. Complete the labs using your textbook, web resources, or the reading assigned for the week.

Readings are short 1-3 page “chapters” covering background topics pertinent to the upcoming lab, particular groups of insects/arthropods, or methods used in Pest Management. This should be read before coming to Lab each week.

Lab Assignments need to be printed and brought to class so that they can be completed as a group in Lab. It is sometimes helpful to read through the assignment ahead of time to get an idea of the subject matter for the week.

Lesson 1 introduces students to the blow fly's life cycle and the accumulated degree hour (ADH) used by forensic entomologists for estimating the time of death. Lesson 2 introduces Dr. Krinsky's entomological work in solving a murder case in 1986. Students access several primary-source documents related to Dr. Krinsky's entomological work. Both lessons help students expand their understanding of a forensic entomologist's work and appreciate how scientists account for environmental/variable factors in forming a conclusion in a scientific study.

Using the Extend 'connect-the-components' visual programming, students can model and simulate ecosystems including social and economic forces as well as study parameter variations to develop an understanding of ecosystem function and productivity.By making 'what if...' changes in the model, the effects of various proposed decisions about the environment can then be shown.EDM includes three ecological systems: Ponds, Grasslands, and Logging. Students can predict results of changes in the models and explore relationships.First, you diagram a model of the system showing parts and connections among them. For example, components of the model, such as the sun, are placed on the computer screen. Each component is linked to the others with a mathematical relationship, such as the transfer of the sun's energy to plants.Values are entered into block dialog boxes to characterize the interactions of the components, such as the amount of sunlight at a particular location or the initial number of bluegill in a pond. When the simulation is run, you can see the growth curves of the various components of the system.

The European Experience brings together the expertise of nearly a hundred historians from eight European universities to internationalise and diversify the study of modern European history, exploring a grand sweep of time from 1500 to 2000. Offering a valuable corrective to the Anglocentric narratives of previous English-language textbooks, scholars from all over Europe have pooled their knowledge on comparative themes such as identities, cultural encounters, power and citizenship, and economic development to reflect the complexity and heterogeneous nature of the European experience. Rather than another grand narrative, the international author teams offer a multifaceted and rich perspective on the history of the continent of the past 500 years. Each major theme is dissected through three chronological sub-chapters, revealing how major social, political and historical trends manifested themselves in different European settings during the early modern (1500–1800), modern (1800–1900) and contemporary period (1900–2000).

This resource is of utmost relevance to today’s history students in the light of ongoing internationalisation strategies for higher education curricula, as it delivers one of the first multi-perspective and truly ‘European’ analyses of the continent’s past. Beyond the provision of historical content, this textbook equips students with the intellectual tools to interrogate prevailing accounts of European history, and enables them to seek out additional perspectives in a bid to further enrich the discipline.

Ontwerpen is een combinatie van logisch redeneren en het creatief combineren van bestaande technieken om tot nieuwe, innovatieve ideeen te komen. Een goede werktuigkundig ontwerper put zijn creativiteit uit kennis van een groot aantal bestaande werktuigbouwkundige systemen. Hoe groter die kennis, hoe groter de kans dat nieuwe, innovatieve ontwerpconcepten ontstaan. Vooral kennis over niet-conventionele techniek bevordert dit creatieve ontwerpproces.

Het doel van het vak Evolving Design is om studenten de onderhavige werkprincipes te tonen van een grote hoeveelheid niet-conventionele werktuigbouwkundige systemen. Er wordt hierbij zowel gekeken naar bijzondere ontdekkingen uit het verleden als uit het heden, met een blik op de toekomst. De ontwerpprincipes worden niet simpelweg opgesomd, maar geplaatst in hun fascinerende, historische ontwikkeling om te laten zien hoe de ontwerpers hun creativiteit en vernuft gebruik(t)en om goedwerkende oplossingen te vinden binnen de beperkingen van de beschikbare fabricageprocessen en beschermingsmogelijkheden (patenten). Veel oplossingen uit het verleden zijn klaar om te worden toegepast in de technologie van de toekomst!

Het vak richt zich primair op het kwalitatief beschrijven van de werkprincipes van bestaande technologieen, met de nadruk op bewegende mechanische constructies. Hoewel het kwantatief, in detail uitwerken van de kracht-bewegingsvergelijkingen niet het hoofddoel van het vak is, zijn mechanische vergelijkingen wel essentieel als zij leiden tot een beter begrip.

This course will examine the main focus that unites existentialists, "existence." Particularly, it will examine the concrete existence of individual human beings. Major figures or study will be, Blaise Pascal, Sóren Kierkegaard, Fyodor Dostoevsky, Friedrich Nietzsche, Martin Heidegger, Jean-Paul Sartre, Simone de Beauvoir, and Albert Camus.

In this activity, students are presented with two objects that have different constant speeds and that will race each other. The students must determine which object will win the race, as well as either how much time elapses between the objects crossing the finish line.

This workbook offers an overview of core educational theories applied in a Higher Education praxis.Addressing such issues and dilemmas as:what is learning? what epistemological and learning theories do we use?, which psychological approaches are applied etc

Throughout the course, we will examine and discuss questions important to feminist politics, such as citizenship, political participation, and political rights; work and family; reproductive rights and birth control; gender representation in the media; and finally, the role of gender in militarism and national security. In considering each topic, we will draw on historical analysis and seek to consider the variety of womenĺÎĺs experiences. Though this course will focus on feminism in the U.S., we will also attempt to incorporate international perspectives on women and feminism.

The course "Fluid Flow, Heat and Mass Transfer," course number ta3220, is third-year BSc course in the program of Applied Earth Sciences at Delft University of Technology. Students in this class have already taken a course in "Transport Phenomena" in the second year, and "Fluid Flow Heat and Mass Transfer" is designed as a follow-up to that class, with an emphasis on topics of importance in applied earth sciences, and in particular to Petroleum Engineering, groundwater flow and mining.
In practice, however I start over again with first principles with this class, because the initial concepts of the shell balance are difficult for students to grasp and can always use a second time through. The course covers simple fluid mechanics problems (rectilinear flow) using shell balances, for Newtonian and power-law fluids and Bingham plastics. Turbulence for Newtonian fluids is covered in the context of friction factors for flow in pipes, flow around spheres and flow in packed beds.
