How do we understand architecture? One way of answering this question is by looking through the lens of history, beginning with First Societies and extending to the 16th century. This course in architectural history is not intended as a linear narrative, but rather aims to provide a more global view, by focusing on different architectural "moments."
How did the introduction of iron in the ninth century BCE impact regional politics and the development of architecture? How did new religious formations, such as Buddhism and Hinduism, produce new architectural understandings? What were the architectural consequences of the changing political landscape in northern Italy in the 14th century? How did rock-cut architecture move across space and time from West Asia to India to Africa? How did the emergence of corn impact the rise of religious and temple construction in Mexico?
Each lecture analyzes a particular architectural transformation arising from a dynamic cultural situation. Material covered in lectures will be supplemented by readings from the textbook A Global History of Architecture.
Join us on a journey around the globe and learn how architecture has developed and interacted with the world’s culture, religion, and history.

The overall objective of the course is to build financial acumen to make you a successful entrepreneur or manager.
Biomass is the only renewable feedstock which contains the carbon atoms needed to make the molecules to create chemicals, materials and fuels. However, the majority of our current scientific and industrial knowledge on conversion is based on processing fossil feedstocks. In this course we explore the relevant fundamental knowledge on (bio)catalytic conversion in order to produce (new) biobased building blocks, chemicals and products.
The design of an effective (catalytic) process for the conversions of biobased feedstocks to desired products is the core of this course. Unique for bioconversion is the presence of the elements O,N, P, S and the large quantities of water.
We therefore will explore:
- microbial, biochemical and chemical (i.e., catalytic) conversion routes.
- how to use catalysts, either heterogeneous, homogeneous or biocatalysts function in order to optimize the process of conversion. We discuss how these catalysts can be tuned and their specific advantages and disadvantages for biobased conversions.
- the influence of the reactor choice as an inevitable asset in the process. We discuss how to describe the productivity of catalytic processes depending on the choice of the reactor and how the choice of the reactor can add to the stability of the conversion process.
The knowledge you gain allows you to design processes specifically targeted on biomass based conversions as well offering an opportunity to interact with chemist, engineers and scientists who mainly focus on the traditional fossil based conversions.
All analytics work begins and ends with a story. Storytelling is the analytics professional’s missing link in delivering the essence of signals and insights from data to executives, management and more for real business results.
In this analytics storytelling course, you’ll learn effective strategies and tools to master data communication in the most impactful way possible—through well-crafted analytics stories.

Explore how to create a sustainable future by moving away from dependence on fossil resources to biomass resources for the production of food, chemicals and energy-carriers.
We’ll focus on five topics in this course:
1. Introduction to Biobased Sciences
Learn about the products that can be derived from biomass and the processes used to do so, compared to current fossil based products and processes.
Biorefinery deals with the challenge of extracting valuable biomass components and converting them to final products. To achieve this you first need knowledge of the different types of biomass, the molecules present and their chemical characteristics. Biorefinery is all about efficient processing. Aspects of processing include the harvesting, pre-treatments, conversion and separation technologies.
3. Consumer Behaviour
Understand the challenges of moving towards a biobased economy and gaining consumer acceptance. How do consumers evaluate products? And how is their perception influenced by communication strategies? Understanding the basics of consumer science will help you to implement a consumer view when developing a product.
4. Biomass production
A biobased economy runs on biomass. It is therefore important to understand which factors play a major role in crop growth, yield formation and quality. In this module you’ll learn to identify design criteria for the production of biobased crops on both a crop and farm level.
5. Achieving Sustainability
Delve into the true meaning of sustainability and how sustainability issues are linked to human activities. Biobased products are not always as sustainable as it seems on first glance. You’ll learn that an understanding of the degree of sustainability requires a thorough analysis of a variety of factors and constituents.
Preventive security and reducing privacy threats are global issues in the 21st century. This world first course investigates the biological traits that uniquely identify individuals such as fingerprints, irises and signatures and the biometric technologies that safeguard against identify theft and electronic fraud.
Have you ever wondered why humans walk on two legs rather than four? In this course, we will explore how science investigates this unusual form of locomotion. We will start our investigation by looking at the mechanics of upright walking in humans and comparing that to bipedal locomotion in large birds, bears, and apes.
We will journey back millions of years into the human fossil record in an effort to understand how and why upright walking evolved. Around our first birthday, each of us learned how to walk, but how does this happen? With bipedalism came costly trade-offs as well-- we’ll examine these aches and pains as byproducts of our evolutionary history.
This course will take an intentionally interdisciplinary approach to studying how and why humans move bipedally. You will be exposed to anthropology, biomechanics, anatomy, evolution and paleontology to explore something deeply human: upright walking.
This course was developed in collaboration with SmithsonianX (National Musuem of Natural History and the National Zoological Park).
Technologies are always being defeated.
If you own an information asset that’s valuable enough to the right adversary, it’s only a matter of time before there’s a breach. Today’s technologies attempt to keep adversaries out, but the sad fact is they will inevitably be defeated. This means a successful cybersecurity professional needs to have an expanded arsenal in their toolkit that extends far beyond technical proficiency.
Cybersecurity professionals need to be agile, multifunctional, flexible, and dynamic given how quickly things can change. They need to be able to adapt to change and problem solve quickly, have diverse knowledge to perform many activities, respond to new threats and shift priorities to meet the challenge of the day.
The purpose of this course is to give learners insight into these type of characteristics and skills needed for cybersecurity jobs and to provide a realistic outlook on what they really need to add to their “toolkits” – a set of skills that is constantly evolving, not all technical, but fundamentally rooted in problem-solving.
Students will learn from thought leaders from both the academic and practitioner communities.
For marketers, an understanding of how a consumer selects, purchases, uses and disposes of products and services is pertinent to successfully managing the marketing function.
In this course, you will learn about the role of consumer behaviour within marketing. We will discuss how this behaviour is shaped by the social and cultural environment, as well as a number of psychological factors.
You will learn about decision-making processes in consumption behaviour in different buying situations. This will develop your ability to integrate marketing processes at a higher level.
Concepts drawn from various disciplines such as psychology, economics and anthropology will be examined.
This course is part of the CurtinX MicroMasters Credential in Marketing in a Digital World that is specifically designed to teach the critical skills needed to be successful in this exciting field. In order to qualify for the MicroMasters Credential you will need to earn a Verified Certificate in each of the five courses.
Las estructuras están implicadas en nuestras vidas: las plantas, los animales, casi todo lo que fabrica el ser humano, incluso nuestro propio cuerpo, deben soportar una serie de fuerzas sin romperse, y por lo tanto prácticamente cualquier elemento de nuestro entorno es una estructura de una clase u otra.
No cabe duda de que entender cómo se comportan las estructuras es fundamental para entender el mundo que nos rodea, para comprender la naturaleza y para juzgar mejor los progresos que ha hecho la humanidad a lo largo de la historia. Sin embargo, los ingenieros hemos fallado una y otra vez cuando hemos intentado explicar esta materia de forma que los no entendidos puedan entender su importancia.
Este curso pretende saltar esa brecha existente entre los expertos en cálculo de estructuras y los profanos utilizando un lenguaje asequible, empleando ejemplos históricos y proponiendo ensayos sencillos que pueden hacerse en casa. El curso abordará no sólo el problema de por qué los edificios y los puentes se caen sino también otras muchas cuestiones. ¿Por qué las ventanas de los aviones son redondas? ¿Por qué los gusanos tienen esa forma? ¿Por qué los murciélagos pueden volar dentro de un rosal sin rasgarse las alas? ¿Cómo funcionan las arterias? ¿Por qué las catedrales góticas pueden ser tan esbeltas? ¿Por qué hay construcciones romanas que siguen en pie 2000 años después? ¿Qué podemos aprender sobre los constructores de las diferentes estructuras que nos han legado nuestros antepasados?
Muchos contenidos de este curso pueden ser útiles para médicos, biólogos, artistas, historiadores y arqueólogos.
We will explain how to start with raw data, and perform the standard processing and normalization steps to get to the point where one can investigate relevant biological questions. Throughout the case studies, we will make use of exploratory plots to get a general overview of the shape of the data and the result of the experiment. We start with RNA-seq data analysis covering basic concepts of RNA-seq and a first look at FASTQ files. We will also go over quality control of FASTQ files; aligning RNA-seq reads; visualizing alignments and move on to analyzing RNA-seq at the gene-level: counting reads in genes; Exploratory Data Analysis and variance stabilization for counts; count-based differential expression; normalization and batch effects. Finally, we cover RNA-seq at the transcript-level: inferring expression of transcripts (i.e. alternative isoforms); differential exon usage. We will learn the basic steps in analyzing DNA methylation data, including reading the raw data, normalization, and finding regions of differential methylation across multiple samples. The course will end with a brief description of the basic steps for analyzing ChIP-seq datasets, from read alignment, to peak calling, and assessing differential binding patterns across multiple samples.
Given the diversity in educational background of our students we have divided the series into seven parts. You can take the entire series or individual courses that interest you. If you are a statistician you should consider skipping the first two or three courses, similarly, if you are biologists you should consider skipping some of the introductory biology lectures. Note that the statistics and programming aspects of the class ramp up in difficulty relatively quickly across the first three courses. By the third course will be teaching advanced statistical concepts such as hierarchical models and by the fourth advanced software engineering skills, such as parallel computing and reproducible research concepts.

The aim of this course is to offer basic cement chemistry to practitioners, as well as new students in the fields of chemistry and engineering.
You will learn how cement is made and hydrated, as well as the environmental and economical benefits it offers. You’ll learn to test your samples in isocalorimetry in order to track the hydration and to prepare and observe samples by scanning electron microscopy. In the last two weeks of the course, you will also learn how X-ray diffraction works and how to apply it to cements.
Because the course is designed for beginning students, it’s not necessary to have a cement background, however basic concepts in chemistry and crystallography will help. This course lasts 6 weeks, during which you can take theoretical courses and tutorials to test the cement in the laboratory.
La Codificación de Audio (también conocida como compresión de audio) es una representación digital de las señales de sonido para ser almacenadas o transmitidas por cualquier medio digital. En este proceso se busca siempre ocupar el mínimo número de bits posible para poder transmitirla por canales limitados en velocidad o bien poder almacenar muchos sonidos o música en el menor espacio posible. Todo ello se debe realizar manteniendo una calidad de sonido cada vez más exigente y, en los últimos años, permitiendo sistemas más avanzados que el estéreo que proporcionan sonido espacial. En este curso veremos los estándares más conocidos, como el MP3, así como otros formatos superiores aparecidos en los últimos años.
- Sección 1: Digitalización y compresión de audio, ¿cómo afecta a nuestra percepción?
- Sección 2: Escalas auditivas y tipos de compresión
- Sección 3: Estándares MPEG de compresión de audio
- Sección 4: Codificadores avanzados de audio
- Sección 5: Evaluación de codificadores
