Multicopter Dynamics and Control: Surviving Extreme Disturbances and Rapidly Generating Trajectories

December 1

Abstract

Flying robots, such as multicopters, are increasingly becoming part of our everyday lives, with current and future applications including personal transportation, delivery services, entertainment, and aerial sensing. These systems are expected to be safe and to have a high degree of autonomy. This talk will discuss the dynamics and control of multicopters, including some research results on trajectory generation for multicopters and fail-safe algorithms. Finally, we will present the application of a failsafe algorithm to a fleet of drones performing as part of a live theater performance on New York's Broadway.

Abstract

Modern computer systems rely heavily on parallel processing. Effectively, on the one hand almost any machine nowadays includes a multicore CPU, even mobile devices. On the other hand, parallel processing capacities are significantly augmented by the graphics processing unit (GPU): general-purpose computing on graphics processing units (GPGPU) is the typical example. In this research, relying on Microsoft’s DirectX 12 programming interfaces, we experiment a novel approach to enable parallel processing for graphical rendering on both the CPU and GPU for the popular Racket functional programming language and development environment (formerly PLT Scheme). And importantly as part of our objective, this is accomplished without compromising Racket’s ease of use and friendliness towards the programmer. In addition, the proposed framework has been empirically evaluated according to various use cases. Performance evaluations measured significant improvements with respect to execution time ([endif]--> speed-up in some cases), CPU utilisation time (reduced by as much as 80% in some scenarios), as well as the frame rate when using animated graphics.

Towards Intelligent Programing Systems for Modern Computing

May 11

Dr. Xipeng Shen, ACM Distinguished Speaker

Abstract

Modern computing exhibits new challenges, which includes the rapid increase of the volume and variety of data, the shift of computing towards cloud and IoT, and the fast development of heterogeneity in processors and memory. To address these challenges, one of the keys exists in making programming systems more intelligent. In this talk, Dr. Shen will present the progresses his group has achieved in the recent years towards that goal. These techniques help raise program analysis and optimizations to a new level, make programming systems self learn and evolve, and helps programs overcome hardware limitations to better harness the power of modern heterogeneous systems (e.g., GPU).

Hats Off Speaker

Prasant Mohapatra, University of California Davis

Abstract

With the expansive usage of mobile devices and potential growth in the deployment of Internet of things, we will have proliferation of smart sensors in our handheld devices, wearables, and in our surroundings. Making sense out of the web of sensors is what we term as Smart-Sensing. Smart-Sensing would involve accurate and innovative sensing approaches while using minimal resources. In this talk, we will have an overview of a few approaches and novel ideas for smart-sensing using smartphones. Capturing the movement of fingers and hand gestures through accelerometer and gyroscope, we will develop the concept of finger-writing using smartwatches. Sensor assisted biometric authentication will be the next topic of our discussion. Then we will explore how the WiFi APs can detect as well as identify humans. The last part of the talk will demonstrate the unconventional use of smart devices. The talk will conclude with the summary of the scope and applications of Smart-Sensing environments.

Disruption in the Transportation Industry – A Discussion on Current Innovation Trends

April 8

Dr. Jane MacFarlane, Lawrence Berkeley National Lab

Abstract

U.S. transportation infrastructure is undergoing a significant transformation. A confluence of technologies - smart devices with location, sensing and connectivity, ubiquitous data networks, and cloud-based computing infrastructures that can handle large amounts of data ingestion and computation - are being used to digitize and deliver new scaled services at a dramatic pace all of which is disrupting the way the automotive and transportation industries do business. The disruption is occurring from the bottom up as these devices become more intelligent, generate new mobility solutions and integrate more effectively into people’s lives. This discussion will focus on introducing a holistic view of data generation, management and analytics to provide science-based big data analytics that support long-term regional planning, will inform future policy decisions and drive a focus on decarbonization of the transportation system.
