The Motivated engineering Transfers - STEM Talent Expansion Program (METSTEP) is a partnership between Arizona State University's (ASU's) Ira A. Fulton schools of engineering (lead institution) and non-metropolitan Arizona Community Colleges (CCs) designed to significantly increase the number of CC transfer students (especially women and underrepresented minority students) that graduate with engineering and computer science - hereafter referred to as engineering - BS/E and graduate degrees. The targeted students are enrolled in pre-calculus/calculus, engineering, biology, chemistry, physics, and geology courses at Arizona's CCs and their local high school (HSs). The partner CCs (Arizona Western, Central Arizona, Cochise, Eastern Arizona, and Mohave) have been selected because (1) they possess a significant pool of untapped engineering talent (a high percentage of women and underrepresented minorities) and (2) they have enthusiastically embraced the vision to reach out to students to attract them to exciting engineering careers. This project develops a supply-chain of high quality engineering students by 1) supporting the CCs' HS student outreach activities, 2) supporting the CC engineering courses by providing materials, tutoring, local engineering speakers, and tuition scholarships, 3) conducting "Be an Engineer" events on the CC campuses to CC students and local HS students and their parents, 4) following up with classes/workshops/seminars - exploiting time-tested techniques, assignments, as well as one-on-one and group mentoring - for all participants either via live teleconference or webcast, 5) providing an engaged community of mentors (with extensive experience and commitment) for all students, as well as remote tutoring and mentoring via phone, email, or Blackboard, 6) hosting an Orientation at ASU specifically for engineering transfer students, 7) managing a Fulton Transfer Center where engineering transfer students and their CC cohorts can study together an

The ability to realize an Intelligent Transportation System (ITS) to improve driver safety has attracted huge interests from researchers this decade. Vehicular Communication covering vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) communication supported by ITS provide ubiquitous internet connectivity among the vehicles to improve safety for drivers. In addition to carrying driver safety messages, such as emergency warning messages, accident alerts and road work messages, multi-hop routing carrying the information for driver's comfort such as long route traffic information, on road advertisements and parking assistance are also an important and challenging task in vehicular ad hoc networks (VANET). This paper presents a multi-hop long range transmission of packets among the vehicles on the basis of reduced transmission hops by choosing the most suitable vehicle within the transmission range for packet transmission. The algorithm proposed in this paper, Fastest Multi-Hop Routing Scheme (FMHR) is evaluated based on incoming and outgoing throughput and compared with another multi-hop transmission algorithm using different radio access technology. The simulation environment used for the evaluation of proposed algorithm is NCTUns-6.0.

This paper presents the improvement of the watershed from propagated markers, a generic method to interactive segmentation of objects in image sequences, by the inclusion of a temporal gradient to the segmentation framework. Segmentation is done by applying the watershed from markers to a gradient image extracted from the temporal gradient sequence and using markers provided by the binding of markers heuristics. The performance of the improved method is demonstrated by application of a benchmark that supports a quantitative evaluation of assisted segmentation of objects in image sequences. Experimental results provided by the combination of temporal gradient with the binding of markers heuristics show that the proposed improvement can decrease the number of human interferences and the time required to process the sequences.

Sensors are being deployed to improve border security generating enormous collections of data and databases. Unfortunately these sensors can respond to a variety of stimuli, sometimes reacting to meaningful events and sometimes triggered by random events which are considered false alarms. The intent of this project is to supplement human intelligence in a sensor network framework that can assist in filtering and real-time decision making from the large volume of data generated. Our conceptual design of a human-computer system is to use off-line learning to identify the important patterns. The critical real-time system uses the identified patterns from off-line learning in a system that relates the risks of false alarms with the length of patterns and the time interval distributions between sensors in the patterns to allow the human to generate intervention decisions. The human would supplement the computer information with the current threat levels and the available resources for reactions.

The Extended Ant Colony Optimization (EACO) metaheuristic is applied to the problem of Metric Temporal Logic (MTL) falsification of nonautonomous hybrid systems. The goal of the MTL falsification problem is to detect operating conditions and input signals that will generate system trajectories that do not satisfy a user provided specification in MTL. A new method for parameterizing the input space using splines and Hermitian polynomials is introduced and the performance of the new algorithm is compared against Monte Carlo testing techniques. It is envisioned that this work will help practitioners in designing complex control or mixed-signal systems.

We present a multi-channel MAC protocol for ad hoc networks, for nodes equipped with a single half-duplex transceiver, combining the use of OFDMA and CDMA. To ease OFDMA channel management the network is clustered. Channel groups are defined by a resolvable balanced incomplete block design (BIBD) to minimize interference. Unique CDMA codes are assigned to each cluster. Clusterheads manage and assign channel groups through an extended handshake. Idle nodes that overhear the handshake cooperate to reduce the incidence of the multi-channel hidden- and exposed-terminal problems, and also the near-far problem of CDMA. Simulation results show a significant improvement in average delivery ratio and delay, especially in dense network topologies.
