My presentation given at the Association for Science Education eastern Region Annula Conference at Stewards School, harlow on 13th March 2010
The main subject of the presentation is an introduction to the west Point Bridge Design Challenge and how to download and use the free software but it also covers me, the ICE, bridges and the basics of bridge design plus also the PASCO bridge kit.
Teaching bridge basics to high school teachers for implementing more engineering curriculum in their classes. This was followed up with many hands on and digital bridge building exercises. Made for the http://www.dyfference.org program.
This is a power point I created for the presentation of a Senior Project at school. The project was the design of a wood pedestrian bridge to connect two buildings on campus. All of the images are my own or used with permission.
I got a bit of creative inspiration from other ppt's on this site, so I thought I would give back as much as I could!

Op Componenten geBaseerde Eindige Elementen Model voor staalverbindingen
Veertig jaar geleden werd numerieke analyse van staalverbindingen door sommige onderzoekers als een niet-wetenschappelijk geval gezien. Twintig jaar later is het reeds een breed gebruikte toevoeging en uitbreiding van het experimentele en theoretische werk. Vandaag is numerieke analyse, en met name numerieke mechanica en vloeistofdynamica, algemeen gebruikt, als een onvervangbaar ontwerphulpmiddel en katalysator voor meerdere onderzoeksgebieden. De aanbevelingen voor de berekening m.b.v. deze geavanceerde, numerieke modellering is hoewel verborgen, maar gereed om te gebruiken volgens hoofdstuk 5 en bijlage C van EN 1993-1-5:2005.
Om de mogelijkheden van de praktische toepassing en de kennis van het gedrag van staalverbindingen te verenigen in de geavanceerde berekening door eindige elementen methode (EEM), is de Componenten geBaseerde Eindige Elementen Model (CBEEM) ontwikkeld. Het model gebruikt de EEM voor de totale berekening van de snedekrachten in de verbinding. Het materiaalmodel gebruikt het elasto-plastische gedrag met de grenswaarde van 5% plastificatie. Het EE-net moet automatisch gemaakt worden en worden geverifieerd, zodat een goede weergave van het gedrag volgens een plastische berekening verkregen wordt.
Met name de verbindingsmiddelen, zoals lassen, bouten of gedrukte, slanke platen worden beschouwd, als een component met een stijfheid, sterkte- en vervormingweerstand. Deze procedure stelt men in staat om de ontwikkeling van de snedekrachten te beschouwen tijdens het belasten van eenvoudige of complexe verbindingen, de juiste beschouwing van de weerstand van de verbinding belast door eenvoudige of complexe belastingsituaties te doen, en de inschatting van de vervormingscapaciteit van de verbindingen en de aansluiting zelf te maken.
De enige manier om de juistheid van de gesimuleerde resultaten in het geval van complexe modellen aan te tonen is via een methodische validatie- en verificatieproces. Om de juistheid van de toepassing van CBEEM voor de berekening van verbindingen te controleren is een hiërarchische verificatie voorbereid t.o.v. de componentenmethode voor verbindingen van open profielen volgens hoofdstuk 6 van EN 1993-1-8:2006 en verbindingen van kokerprofielen in ISO 14346:2014. De validatie tegen gepubliceerde en eigen experimentele resultaten is gebruikt voor complexe situaties. Deze benchmark resultaten zijn beschikbaar voor de gebruiker om het juiste gebruik van het hulpmiddel toe te staan.
Het seminar zal de huidige stand van zaken m.b.t. verbindingsontwerp opsommen. Tevens zal de methode van het CBEEM-hulpmiddel worden getoond aan de hand van software.
the presentation gives a brief description about the architectural and engineering design and the construction methodologies applied and some statistical and engineering data
These slides are very help for the Diploma (civil engineering) as well students and those students who have great interest in model making. Some of the important models taken as a projects are Eiffel tower model, Geodesic dome, Load bearing spaghetti tower, spaghetti arch truss bridge, load bearing pops sticks truss bridge, load bearing pops sticks arch bridge, cable stayed bridge, Suspension bridge & hydraulic bridge.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
