| "Multi-Object Tracking for Automotive Systems" |
| "Autonomous vehicles, such as self-driving cars, rely critically on an accurate perception of their environment. In this course, we will teach you the fundamentals of multi-object tracking for automotive systems. Key components include the description and understanding of common sensors and motion models, principles underlying filters that can handle varying number of objects, and a selection of the main multi-object tracking (MOT) filters. The course builds and expands on concepts and ideas introduced in CHM013x: ""Sensor fusion and nonlinear filtering for automotive systems"". In particular, we study how to localize an unknown number of objects, which implies various interesting challenges. We focus on cameras, laser scanners and radar sensors, which are all commonly used in vehicles, and emphasize on situations where we seek to track nearby pedestrians and vehicles. Still, most of the involved methods are more general and can be used for surveillance or to track, e.g., biological cells, sports athletes or space debris. The course contains a series of videos, quizzes and hands-on assignments where you get to implement several of the most important algorithms. Learn from award-winning and passionate teachers to enhanceyour knowledge at the forefront of research on self-driving vehicles. Chalmers is among the top engineering schools that distinguish itself through its close collaboration with industry."

| "Electric and Conventional Vehicles" |
| "Electric powertrains are estimated to propel a large part of road vehicles in the future, due to their high efficiency and zero tailpipe emissions. But, the cost and weight of batteries and the time to charge them are arguments for the conventional powertrain in many vehicles. This makes it important for engineers working with vehicles to understand how both these powertrains work, and how to determine their performance and energy consumption for different type of vehicles and different ways of driving vehicles. This course is aimed at learners with a bachelor's degree or engineers in the automotive industry who need to develop their knowledge about electric powertrains. In this course, you will learn how electric and conventional combustion engine powertrains are built and how they work. You will learn methods to calculate their performance and energy consumption and how to simulate them in different driving cycles. You will also learn about the basic function, the main limits and the losses of: Combustion engines, Transmissions Electric machines, Power electronics Batteries. This knowledge will also be a base for understanding and analysing different types of hybrid vehicles, discussed in the course, Hybrid Vehicles. As a result of support from MathWorks, students will be granted access to MATLAB/Simulink for the duration of the course."

| Hybrid Vehicles |
| "Why are hybrid vehicles still more common than battery electric ones? Why are electric vehicles still more expensive than conventional or hybrid ones? In this course, you will get the answers to this and much more. While electric motors can improve vehicles regarding performance, energy consumption and emissions, they suffer from high cost and weight of batteries. Smart combinations of electric motors and combustion engines in a hybrid powertrain can combine these strengths with the advantages of combustion engines. This course is aimed at learners with a bachelor's degree or engineers in the automotive industry who need to develop their knowledge about hybridpowertrains. Inthis course, we willexamine different mechanical layouts of hybrid powertrains and how they influence the performance and complexity of the powertrain.

In this course, you will learn these key concepts through a motivating case study on election forecasting. This course will show you how inference and modeling can be applied to develop the statistical approaches that make polls an effective tool and we'll show you how to do this using R. You will learn concepts necessary to define estimates and margins of errors and learn how you can use these to make predictions relatively well and also provide an estimate of the precision of your forecast. Once you learn this you will be able to understand two concepts that are ubiquitous in data science: confidence intervals, and p-values. Then, to understand statements about the probability of a candidate winning, you will learn about Bayesian modeling. Finally, at the end of the course, we will put it all together to recreate a simplified version of an election forecast model and apply it to the 2016 election."

| "Data Science: Probability" |
| "In this course, part of our Professional Certificate Program in Data Science,you will learn valuable concepts in probability theory. The motivation for this course is the circumstances surrounding the financial crisis of 2007-2008. Part of what caused this financial crisis was that the risk of some securities sold by financial institutions was underestimated. To begin to understand this very complicated event, we need to understand the basics of probability. We will introduce important concepts such as random variables, independence, Monte Carlo simulations, expected values, standard errors, and the Central Limit Theorem. These statistical concepts are fundamental to conducting statistical tests on data and understanding whether the data you are analyzing is likely occurring due to an experimental method or to chance. Probability theory is the mathematical foundation of statistical inference which is indispensable for analyzing data affected by chance, and thus essential for data scientists."

| "Data Science: Wrangling" |
| "In this course, part of our Professional Certificate Program in Data Science,we cover several standard steps of the data wrangling process like importing data into R, tidying data, string processing, HTML parsing, working with dates and times, and text mining. Rarely are all these wrangling steps necessary in a single analysis, but a data scientist will likely face them all at some point. Very rarely is data easily accessible in a data science project. It's more likely for the data to be in a file, a database, or extracted from documents such as web pages, tweets, or PDFs. In these cases, the first step is to import the data into R and tidy the data, using the tidyverse package. The steps that convert data from its raw form to the tidy form is called data wrangling. This process is a critical step for any data scientist. Knowing how to wrangle and clean data will enable you to make critical insights that would otherwise be hidden."

| "Data Science: Linear Regression" |
| "Linear regression is commonly used to quantify the relationship between two or more variables. It is also used to adjust for confounding. This course, part ofourProfessional Certificate Program in Data Science, covers how to implement linear regression and adjust for confounding in practice using R. In data science applications, it is very common to be interested in the relationship between two or more variables. The motivating case study we examine in this course relates to the data-driven approach used to construct baseball teams described in Moneyball. We will try to determine which measured outcomes best predict baseball runs by using linear regression. We will also examine confounding, where extraneous variables affect the relationship between two or more other variables, leading to spurious associations. Linear regression is a powerful technique for removing confounders, but it is not a magical process. It is essential to understand when it is appropriate to use, and this course will teach you when to apply this technique."

| "Data Science: Visualization" |
| "As part of our Professional Certificate Program in Data Science, this course covers the basics of data visualization and exploratory data analysis. We will use three motivating examples and ggplot2, a data visualization package for the statistical programming language R. We will start with simple datasets and then graduate to case studies about world health, economics, and infectious disease trends in the United States. We'll also be looking at how mistakes, biases, systematic errors, and other unexpected problems often lead to data that should be handled with care. The fact that it can be difficult or impossible to notice a mistake within a dataset makes data visualization particularly important. The growing availability of informative datasets and software tools has led to increased reliance on data visualizations across many areas. Data visualization provides a powerful way to communicate data-driven findings, motivate analyses, and detect flaws. This course will give you the skills you need to leverage data to reveal valuable insights and advance your career."

| "Souvent confinée à l'étude des techniques permettant de vendre une encyclopédie en 24 volumes à une octogénaire récalcitrante ou à l'art de marchander son salaire, la négociation est souvent abordée sous un angle exclusivement utilitariste. Mais négocier ce n'est pas se limiter à la recherche du bénéfice maximum. La négociation traverse toutes les dimensions de la vie humaine. Nous négocions tous les jours, dans toutes les sphères de notre existence : au travail, avec la famille, les amis… Dès qu'il s'agit de partager des biens matériels mais aussi de résoudre une divergence d'intérêts, de concilier différentes envies, rêves, goûts, couleurs… Ce cours s'éloigne de l'approche classique des négociations et tente de rendre compte des phénomènes psychologiques à la base du comportement. L'approche poursuivie sera descriptive plutôt que prescriptive. Contrairement aux théoriciens du jeu qui « examinent ce que de super-hommes, ultra-intelligents et impeccablement rationnels devraient faire dans les situations compétitives », nous explorerons la façon dont « des êtres imparfaits se comportent dans la réalité » (Raiffa, 1982, p. 21). Ainsi, les êtres humains poursuivent des motivations, ont des attentes, des préjugés, des biais et des émotions. Ils analysent l'information qui leur est soumise et prennent des décisions à travers le spectre de leurs propres limites cognitives. Leurs actions fluctuent en fonction de la situation ou de leur personnalité. Toutes ces variables influencent non seulement le comportement des personnes mais, plus fondamentalement, elles modifient la dynamique même de résolution des divergences. Ce cours mettra en évidence ces variables multiples et offrira aux étudiantes et étudiants une compréhension fine et detaillée des processus psychologiques qui entrent en jeu avant, pendant et après toute négociation. Ce cours sera enseigné en français."

| "Introducción a la Ciencia de Datos y el Big Data" |
| "El futuro pertenece a la ciencia de datos y a quienes la entiendan. Al igual que el petróleo y el gas impulsaron las economías de los siglos XX y XXI, los datos impulsan cada vez mas la innovación y la economía global a medida que avanzamos hacia una nueva era denominada la revolución digital. Las empresas que están cambiando a una mentalidad de datos van a obtener primero una enorme ventaja competitiva. Esto se ha convertido en una verdad universal: las empresas modernas se están inundando de big data. El año pasado, McKinsey estimó que las iniciativas de Big Data en el sistema de salud de los Estados Unidos, ""podrían representar de $300 mil millones a $450 mil millones en gastos de salud reducidos o del 12 al 17 por ciento de la línea de base de $2.6 billones en costos de salud de los Estados Unidos"". Por otro lado, sin embargo se estima que los datos erróneos le cuestan a los Estados Unidos apróximadamente $3.1 trillones de dólares al año. Aunque la ciencia de datos representará ventajas puntuales para las empresas como mitigar el riesgo y/o el fraude; entregar al cliente productos relevantes y tener experiencias personalizadas al mismo, es sin embargo, importante notar que la ciencia de datos podrá agregar un valor a cuaquier negocio, siempre y cuando pueda usar bien sus datos.

Las herramientas de ciencia de datos o Data Science pueden ser de dos tipos: Uno para aquellos que tienen conocimientos de programación Otro para los usuarios comerciales. Las herramientas para el primer tipo, tienen que ver con el área de las tecnologías de información en donde se busca que la persona tenga conocimientos de algún lenguaje de programación como R o Python y comunmente a estas personas se les denomina científicos de datos. Las herramientas que son para usuarios comerciales se enfocan en automatizar el análisis de datos; en este tipo, los usuarios tienen conocimientos básicos de un lenguaje de programación, pero un fuerte conocimiento del área de dominio; por lo que se han empezado a llamar ciudadanos cientificos de datos. Estas herramientas te permitirán tomar las mejores decisiones basadas en el análisis de datos (también conocido como inteligencia de negocios)."

En este curso online conoceras una parte importante de la ciencia de datos o Data Science; la visualización de los datos y las herramientas que puedes usar para aplicarlos. Debido a la forma en que el cerebro humano procesa la información, usar tablas o gráficos para visualizar grandes cantidades de datos complejos es mas fácil que analizar hojas de cálculo o informes. La visualización de datos es una forma rápida y fácil de transmitir conceptos de manera universal, y es posible el poder experimentar con diferentes escenarios haciendo pequeños ajustes. La visualización de datos es la presentación de datos en un formato gráfico. Permite a los tomadores de decisiones ver el análisis presentados visualmente, para que puedan comprender conceptos dificiles o identificar nuevos patrones. La visualización de datos revela informacion inadvertida, especiamente en grandes conjuntos de datos (big data); da respuestas mas rápido; y ayuda a entender mas fácilmente la relación causa-efecto."

| "Introduction to Sociology" |
| "Very often we see, hear or experience things that seem ""strange"" and incomprehensible to us. We start to wonder about the world around us, asking questions like: “How do certain people become billionaires when others are homeless? Why do humans worship Gods or form families? What makes killing in war acceptable but not in any other situation?” If you have ever wondered about these issues and/or other, you aren’t alone. Similar questions have been asked since the beginning of history, and searching for objective answers using scientific research is the goal of sociology. This course is designed to look critically and analytically through different sociological perspectives, including the functionalist, interactionist, conflict and feminist, to help us realize the extent to which society guides our thoughts and actions. The course material provides a fresh, new look at societies and cultures—more objective, full of inquiry and analysis, striving towards social justice and change. Sociology urges us to draw connections between public issues and personal problems, to see the strange as familiar and the familiar as strange, and to examine biography in a historical and social context. Issues of inequalities, social class, race, sexual orientation, disability, age and gender are critically examined within a global perspective in this course. You do not need any prior knowledge of sociological theories or methods to take this class. Bring your life experiences and knowledge, and see how the Sociological Imagination will allow you to dispel cultural myths and reframe reality. This course will cover topics found on the CLEP Sociology exam."
