Design Automation of Things: Power Consumption Characterization, Modeling and Estimation of Electric Vehicles

Title: Design Automation of Things: Power Consumption Characterization, Modeling and Estimation of Electric Vehicles

Speaker:  Professor Naehyuck Chang

Date/Time:  Tuesday, February 10, 2015, 2:00pm to 3:00pm

Location:  Harut Barsamian Colloquia Room (EH 2430)

Host: Nikil Dutt

Abstract:

Rapid electric vehicle (EV) penetration gives a threatening challenge in electric energy generation. An 1,814 kg curb weight full electric vehicle driving 18,129 km/year consumes electricity energy equivalent to 74% of the total residential electricity use per person in the US. This implies that 27% more nationwide electricity generation is needed when 70% of passenger vehicles are replaced with EVs.

This talk introduces the first step toward systematic EV design-time and runtime optimization. We develop instantaneous power consumption modeling of an EV by the curb weights, speed, acceleration, road slope, passenger and cargo weights, motor capacity, and so on, as a battery discharge model. The model also considers the onboard charger, regenerative braking and so on, as a battery charge model. To insure model fidelity, we fabricate a lightweight custom EV, perform extensive measurement, and derive model coefficients using multivariable regression analysis. We estimate the EV instantaneous power consumption of a given speed and route profiles and verify the estimation fidelity with a real test run data. This talk will also cover the on-going project for the next version electric vehicle with four-wheel drive capability.

 

 
Inertial and Bio-potential-based Wearable Computers: Algorithms and Applications

Title: Inertial and Bio-potential-based Wearable Computers: Algorithms and Applications

Speaker:  Professor Roozbeh Jafari

Date/Time:  Thursday, February 12, 2015, 11:00am to 12:00pm

Location:  Donald Bren Hall 4011

Host: Eli Bozorgzadeh

Abstract:

Wearable computers bring to fruition many new opportunities to continuously monitor human body with sensors placed on body; whether they are intended to detect an early onset of a disease, assess human performance or determine the effectiveness of a treatment. In the past few years, the community has observed a large number of applications leveraging wearable computers. There are, however, a number of fundamental challenges that need to be addressed before realizing the true ubiquitous use of the wearable computing systems.

In the first half of the talk, we highlight several inertial-based wearable applications including systems capable of monitoring activities of daily living (ADLs) and home exercises for senior citizen. We focus on a class of signal processing algorithms that provide extreme robustness leveraging accelerometers and gyroscopes. We present our results on ADLs and highlight our efforts in line with data dissemination for the scientific community. In the second half of the presentation, we focus on dry-contact electroencephalography (EEG). We present our brain-computer interface (BCI) system developed for intensive care units leveraging dry-contact EEG. We outline several components of EEG systems and focus on skin-electrode contact noise.

We provide techniques for noise reduction including contact reconfiguration along with experimental verifications. We provide concluding remarks on the trends of wearable computing technology development and future directions.
