Developing And Assessing A Case Study For Teaching Engineering Entrepreneurship At San Jose State University, Anuradha Basu, Minnie Patel
Developing And Assessing A Case Study For Teaching Engineering Entrepreneurship At San Jose State University, Anuradha Basu, Minnie Patel
Faculty Publications
In this paper the authors share their experience of developing a case study for teaching engineering entrepreneurship and subsequently developing assessment and instructional material for the case. We also present the lessons learned from that experience. The authors developed the case study in question on the basis of a survey of engineering students’ perceptions of entrepreneurship6. Our survey showed that many students were interested in entrepreneurship, but were hesitant about starting their own business. We proposed two complementary approaches to learning, namely, case studies and active learning, to enhance the engineering students’ understanding of the entrepreneurial process and dispel some …

Climate change is a pressing issue for the world today. There are an increasing number of technological by-products posing a threat to the stability and quality of the world environment. According to the United Nations’ Intergovernmental Panel on Climate Change (IPCC), global warming appears to be accelerating, resulting in higher increases in global temperature and higher rises in the sea level. To effectively address this problem, there is a need for transdisciplinary, transnational approaches, reflecting the complexity of the problem and the interdependence of people’s lives around the world. Consequently, the Davidson College of Engineering at San José State University …
Barriers To Mitigation: A Pilot Study, James Lee, Crystal Paul, Guna Selvaduray
Barriers To Mitigation: A Pilot Study, James Lee, Crystal Paul, Guna Selvaduray
Faculty Publications
This pilot research was undertaken to discover barriers that prevent homeowners from mitigating earthquake hazards in their homes. There is a relatively significant body of literature on disaster mitigation, which is reviewed and summarized in this report. However, no studies address how these barriers may be overcome so that homeowners would be more proactive in mitigation. If the barriers can be identified, then future communications and policy actions that address these barriers can be taken, resulting in more widespread mitigation implementation that reduces the injury and damage potential that communities face, leading to a reduction in the post-disaster response requirement, …

Mobility Handling In Mac For Wireless Ad Hoc Networks, Anjali Raja, Xiao Su
Faculty Publications
Wireless Sensor Networks (WSNs) are becoming popular in a wide variety of applications. In a WSN, sensor nodes can be static or mobile, depending on applications. Handling mobility in a sensor network can pose interesting challenges in sensor protocol design, and special algorithms are needed to adapt to mobility in the network. In this paper, we survey the current state of art in handling mobility in sensor networks. We first study how mobility affects the design of different layers in the sensor network architecture, and then take a closer look at mobility handling in the MAC layer. We also describe …

Query Recommendations For Interactive Database Exploration, Gloria Chatzopoulou, Magdalini Eirinaki, Neoklis Polyzotis

Relational database systems are becoming increasingly popular in the scientific community to support the interactive exploration of large volumes of data. In this scenario, users employ a query interface (typically, a web-based client) to issue a series of SQL queries that aim to analyze the data and mine it for interesting information. First-time users, however, may not have the necessary knowledge to know where to start their exploration. Other times, users may simply overlook queries that retrieve important information. To assist users in this context, we draw inspiration from Web recommender systems and propose the use of personalized query recommendations. …

A Trade-Off Analysis Of Energy Detectors And Partitioned Search For Primary Detection, Birsen Sirkeci-Mergen, Vishal Sawant, Robert H. Morelos-Zaragoza

Cognitive radios aim to coexist in the unused spectrum bands which are licensed to primary users without harming the primary transmission/reception. For a cognitive radio, it is important to detect the band in which the primary is operating as fast as possible and with high reliability in order to adapt its transmission. In this work, we propose P-partitioning method in combination with energy detectors for the search of the band that the primary user is operating. In the P-partitioning method, the spectrum bands are categorized into P groups and the group that the primary band belongs to is detected in …
An Adaptive Adjacent Channel Interference Cancellation Technique, Robert H. Morelos-Zaragoza, Shobha Kuruba
An Adaptive Adjacent Channel Interference Cancellation Technique, Robert H. Morelos-Zaragoza, Shobha Kuruba
Faculty Publications
In this paper, an adaptive adjacent channel interference (ACI) technique is proposed. Results for BPSK modulation with rectangular and square-root raised-cosine pulse shaping, under AWGN conditions, are obtained showing the proposed method to be effective in improving performance under high levels of interference. Basically, the idea is to send pilot signals and then to use them in estimating the amount of ACI in the frequency domain. The estimated spectral error is used to modify tap weights of an adaptive frequency-domain filter. Our simulation results reported suggest that ACI can be effectively reduced with the proposed technique. At the system level, …
