This paper presents an update on the implementation of a touch-based optical sensor (TTT sensor) for monitoring the alcohol concentration in the driver of a vehicle. This novel sensor is intended to improve driver safety by providing a non-intrusive means of notifying a driver when their blood alcohol concentration may be too high to operate a vehicle safely. Details on implementation of the MARK2 system are presented along with updates on principles of the MARK3 version currently under development. Laboratory validation of the MARK2 system on standard calibration standards are presented along with discussion of next steps in validation of the technology. Updates on the demonstration vehicle implementation are also provided along with lessons learned in the implementation of the human-machine interface aspect of the design.
This paper presents an overview of the theory and implementation of a touch-based optical sensor (TruTouch sensor) for monitoring the alcohol concentration in the driver of a vehicle. This novel sensor is intended to improve driver safety by providing a non-intrusive means of notifying a driver when their blood alcohol concentration may be too high to operate a vehicle safely. The optical alcohol detection system has successfully completed several stages of development and validation. A commercially available, industrial version of the system (TruTouch 2500, or Mark 1) has undergone extensive clinical testing and field validation. Under the DADSS (Driver Alcohol Detection System for Safety) Program, a compact semiconductor version (Mark 2) of the optical system has been developed targeting use in consumer vehicles. Based on proven semiconductor laser technologies, the Mark 2 sensor system has demonstrated excellent spectral accuracy and precision and is currently undergoing laboratory validation testing. A demonstration vehicle version of the system has been designed and will be implemented following completion of the laboratory validation testing.
Using a 512 x 512 Photometrics CCD camera on the 31" telescope operated by the National Undergraduate Research Observatory in Flagstaff, Arizona, we have obtained B,V,R,and I frames of several recent supernovae, most of them observed near peak brightness. The most extensive of these observations, of SN1994D, cover 15 days in March and April, 1994, while the other supernovae, 1993G, 1994I, 1994M, 1994S, and 1994Q, are only sparsely sampled. We present light curves of SN 1994D, along with tables of all the observed magnitudes. We also discuss several alternative procedures used to minimize contamination from the background galaxies and we outline the methods used to reduce our instrumental magnitudes to the standard system. This work was supported by grants from the National Science Foundation RUE program, the NASA Space Grant program, and Gettsyburg College. We acknowledge the support of Lowell Observatory for the use of the 31" telescope on Anderson Mesa by students and faculty of NURO.
Assigning cryptographic attacks as labs in cybersecurity classes is an excellent way to reinforce basic concepts and convey the importance of following cryptography best practices, but there must be a balance between assigning realistic attacks and assigning attacks that the majority of students can readily understand and implement. On the one hand, students will understand the societal impacts better if the attack they implement mirrors a real attack on a real software product, with real-world implications. On the other hand, many real-world cryptographic attacks are too complex for an assignment in an introductory class.
In this short paper, we describe a new lab assignment that we developed (and are releasing open source) that is based on a real-world attack on Tencent QQ Browser's RSA implementation. This assignment is a padding oracle attack on the malleability of RSA, and mirrors a real attack that we implemented on a product with hundreds of millions of users. Because this software product used "textbook RSA", our padding oracle attack is very simple and easy to understand. As a lead-in to describe the attack and lab, we will demo some student-created visualizations of related attacks for a previous lab based on Cipher Block Chaining.
The Online Journal of Astronomy Education has been formed as an experiment whose aim is to fill in a need for information exchange in astronomy education. There is a lack of forums for the publication of innovative astronomy teaching techniques. With this journal, we hope to meet the needs of the astronomy teaching community. The Online Journal of Astronomy Education (OJAE) is made up of three main parts: 1. The Main Journal, a peer reviewed journal. 2. The Forum, an open section for those who want to make contributions and ask questions, without having to deal with the peer review process. And 3. Other Astronomy Resources, pointers to other astronomy sources. The journal is in hypertext format and is available over the world wide web. Submissions to the main journal are accepted in plain text and html format. Submissions to the forum are accepted in plain text, html format, and postscript format. The address of OJAE is: http://artsci.tvi.cc.nm.us/OJAE .
