Learn about the role of dogs in the culture of Papua New Guinea in this video segment from Nature.
In dit college wordt een introductie gegeven van een groot aantal facetten van de scheepshydromechanica en hun onderlinge samenhang zoals die later in de studie meer als geisoleerde onderwerpen aan bod komen. Behandeld worden: de hydrostatica, de geometrie beschrijving van het schip, inleiding lijnenplan, het begrip stabiliteit, de stabiliteit van drijvende lichamen, eenvoudige stabiliteit berekening bij kleine helling hoeken, de weerstand van lichamen onder water en aan het oppervlak, eenvoudige weerstand benaderings methoden voor schepen, de model wetten in de hydromechanica, de extrapolatie methode van Froude, de lift van een vleugel, de vleugel karakteristieken, de toepassing hiervan bij voortstuwing en bij scheepsschroeven, de schroef karakteristieken en een eenvoudige schroef berekening, en tenslotte de fysica van het zeilen en zeilvoortstuwing. Leerdoelen De student kan: 1. de basis van systeem analyse beschrijven (buitenwereld, interfaces, beperkingen, objecten, relaties enz.) 2. maritieme systemen zoals schip/motor/schroef beschrijven en modelleren met behulp van beperkte systeem analyse methodologie; eenvoudige maritieme systemen modelleren door onderverdeling in subsystemen en componenten 3. evenwicht condities van maritieme systemen bepalen en kwalitatief analyseren 4. de definities en belangrijkste karakteristieken van weerstand, voortstuwing en manoeuvreren (snelheid, weerstand, vermogen, RPM, draaicapaciteit) begrijpen en toepassen 5. de relaties tussen algemeen vloeistof dynamica en scheepshydromechanica (bijv. lift/aerodynamica/zeilen; visceuze stroming/Reynolds getal/volgstroomvelden/voortstuwingsrendement; laminair & visceuze stroming/weerstand; niet visceuze stroming/golf patronen/weerstand) beschrijven 6. de achtergrond van de belangrijkste schaal regels (Newton, Froude, Reynolds) d.m.v dimensie analyse uitleggen 7. schaalregels voor schaalmodel experimenten in een sleeptank toepassen en potentiĚÇle complicaties identificeren
ISKME's OER Commons Teacher Training Initiative offers teachers a collaborative professional development model centered on engagement with Open Educational Resources (OER). The OER Commons Teacher Training Initiative is rooted in the idea that equitable access to high-quality education is a global imperative. Open Educational Resources, or OER, offer opportunities for systemic change in teaching and learning through accessible content, and importantly, through embedding participatory processes and effective technologies to engage with learning for all.
In this Wide Angle video, view a city area where illegal migrants from rural China live and work.
Meet two sisters who have migrated from Poland to Ireland, one of three countries in the EU that welcomes immigrant workers from Eastern Europe, in this Wide Angle video.
In this Wide Angle video segment, a young Indian girl talks about her life, family, education and daily routine.
This Wide Angle video segment explores economic and religious development in Kayseri, a city in central Turkey.
Simply put, this is one of my most favorite topics when it comes to talking about computers. In this video we layout the order of this lesson, as well as give basic definitions of:
•Machine-Level Security
•Network Security
•Internet Security
•Social Engineering
The act of physically protecting the computers. The first rule of any type of computer safety is restricting physical access to it. If a bad guy can get their hands on the computer assume they will be able to gain access to all data contained within.
Our third video in our Information Security series (part of the Introduction to Computer course) focuses on Authentication. Authentication is basically proving you are who you say you are
There are three forms of authentication
•Something you know
•Something you have
•Something about you
This video focuses on date protection. We look at how to migrate your data from old to new devices, the importance of data backup AND how to make sure no one can steal your data off a discarded hard drive.
Data is always priceless
Three topics:
-Data migration
-Data backup
-Data disposal
Steps taken to protect computer networks. We cover permissions, user policies (especially how they can get you fired), expectations of privacy, and wireless security.

Our 6 video in the Information Security series (part of Introduction to Computers). We introduce students to the concept of Internet Security.
Specifically we look at defining the players: hackers, crackers, and script kiddies. We also look at steps the home user should take to harden the computer: keep their computer updates, run anti-malware software, and have a firewall.
Video 7 of our information security series (part of Introduction to Computers) we examine malware. Malware is a blanket term that means malicious code, it includes things like viruses, Trojans, worms and spyware.

Our last video in the Information Security lesson covers my favorite topic, social engineering. In this video we look at: Dumpster Diving, Shoulder Surfing, Tailgating, and Spam & Phishing.
I also tell the story about how I used tailgating to get access to a classroom at the FBI Academy.
