Space frame , space structure and geodesic domesNarendra Shah
our presentation will provide information about space frame , space structures and geodesic domes, these technology used to cover large/long span shed, beautification of buildings.
The aim of this PPT is to take an overview of the ‘membranes’ in cable and membrane structures. Before installation on site a membrane has to go through several stages right from design including the steps as form finding, load analysis and design of fabric geometry. The paper also talks about several shapes and forms a membrane can achieve and the principle behind the design of these shapes. Important aspect of membrane structure is availability of membranes in market. This paper accounts various available covering materials in the market and the criteria have to be considered before their installations on the site. Joinery plays a significant role in attaining the required shape and equilibrium. This PPT takes a review of significant junctions in a membrane structure.
a space frame or space structure is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior support

Timber is a renewable building material which has been in use since early ages. Timber needs to be used in the way which minimizes the wastage, because when we cut a tree, it has massive negative impact to the environment. So, when look from this point of view, it is better to reduce usage of timber. But when consider materials for structural elements, substitutes for timber such as concrete, steel, fiber glass, plastic, glass, etc., effect to the environment after demolishing structures which are built from these substitutes is huge which is not done by timber. Therefore, use of timber effectively in construction industry has become a timely need.
Lot of research has been carried out to gain the maximum output from timber. From that lot of products have been made. As an example, use of composite timber products, built up sections can be identified. Most architects tend to use timber in their designs mainly to give the structure an esthetically pleasing output.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Definition:
• Tension roofs or canopies are those in which
every part of the structure is loaded only in
tension, with no requirement to resist
compression or bending forces. Vandenberg; page 6

Shapes
• Anticlastic Surfaces
• The centers of curvature of
the membrane are on
opposite sides of the
membrane e.g. hyperbolic
parabaloid, torus
7. Carnegie Mellon • Department of Architecture • Third Year Studio
Shapes
• Synclastic Surfaces
• The centers of
curvature of the
membrane are on the
same side of the
membrane. E.g sphere
or balloon

A Simple Paraboloid
• Defined by a Minimum of Four Points w/ at
Least One out of Plane
9. Carnegie Mellon • Department of Architecture • Third Year Studio
Equilibrium Forces
• Anticlastic Surfaces
• The surface is stabilised because the tension forces
from prestressing or load are in equilibrium.
• Synclastic Surfaces
• The surface is stabilised because the tension forces
from internal pressure are in equilibrium with the tension
forces in the membrane.

Deformations
• By definition, the membrane can only resist
forces in tension, so forces perpendicular to the
membrane cause large deformations and large
membrane forces.
• Tensile roofs are susceptible to vibration.
• Reverse curvature and/ or prestressing can bring these
forces to zero.
