Currently, most of the SV companies employ underrepresented minorities (URMs) and women at a percentage that is not representative of the U.S. population or degrees awarded to engineers. However, are the percentages representative with respect to URMs and women earning engineering degrees? This paper assesses the use of population parity as an adequate benchmark for measuring diversity in industry using SV as a case study. This work suggests using a novel measure called degree parity as a more appropriate measure. Furthermore, this paper addresses some of the factors that hinder companies from reaching degree parity and offers recommendations as to how companies can improve their diversity record. Results from our analyses indicate that for women, blacks, and Hispanics/Latinos, no company has reached population parity in regards to all domestic employees. However, for women, every SV company has met degree parity when looking at the overall representation of their respective companies. For women in the technical business sectors, only two SV companies have reached degree parity. For blacks, three out of the eleven largest SV companies have reached degree parity in both their overall company representation and technical business sectors. In regards to Hispanics/Latinos, one company has reached degree parity when looking at overall representation and technical business sectors. For Asian Americans, every SV company has met and exceeded degree and population parity in regards to overall representation and technical business sectors. For Whites, only one SV company has met and exceeded degree and population parity with respect to overall representation and technical business sectors. Colleges, universities, and companies continue to work hard to increase the numbers of successful URM and women students in the pathway to engineering careers. A more thorough review of the recruitment and promotion process is needed to ensure that the culture and environment of SV companies are equipped to receive and retain a more diverse pool of graduates and impact diversity in all areas of employment.

For mobile devices, individual nodes should have the ability to propagate messages to interested users over ad-hoc wireless connections thereby removing the dependence on Internet and centralized servers. These nodes are sometimes stationary, but are often mobile, creating intermittent networks of nodes that tend to be socially related. In this paper, we propose LESC, a delaytolerant message delivery protocol, which facilitates efficient message dissemination in a decentralized, ad-hoc fashion and can be implemented using a commodity mobile communication technology such as Bluetooth LE. By leveraging the frequent collocation of socially related peers, nodes strategically become information carriers with the ability to propagate messages to out of range nodes in the future. We design a discrete event simulator that utilizes actual traveling paths derived from Google Maps. The simulator emulates LESC and the epidemic routing protocol to determine if we can achieve reasonable performance. Related works have approached the problem of publish-subscribe systems on mobile devices, but to the best of our knowledge, have not shown the feasibility of a protocol that can directly be implemented over current commodity wireless technologies. We simulate the protocol in Matlab and allow nodes to have multiple publications and subscriptions simultaneously.

The device was designed using an off the shelf motor, microcontroller, DAQ, and force transducer. Once the device was put together a program was written in matlab to control the motor. Tests were done to replicate a spring damper system and once this system was realized, tests were done to replicate the Duffing oscillater that exhibits subcritical pitchfork bifurcation. The finished device can be used to investigate how vision and tactile integration play a role in dynamic manipulation.
