Comparative Water Quality of Cozine, Gooseneck and Mill Creeks

The environmental research methods class of fall 2013 analyzed the water quality of three creeks in the Yamhill (Oregon) Watershed: Cozine, Gooseneck, and Mill Creeks. Our research builds on data collected by previous years\u27 classes (Colahan et al. 2011; Weinbender and Crane 2011; Bailey et al. 2012). The goals of the project were to gain a better understanding of water quality at each site, see how the sites differ, determine causes for any differences, and examine changes in water quality over time. Because Cozine is surrounded by an urban environment, whereas both Gooseneck and Mill are in a rural setting, we hypothesized that Cozine would have the lowest overall water quality. The Greater Yamhill Watershed Council did restoration projects in Gooseneck Creek (Waterways Consulting 2013), so we also hypothesized that the water quality should be improving over time in Gooseneck and Mill. Testing the combination of these three sites allowed us to compare urban vs. rural effects on water quality

Millennials on the Move, but to Where?

The following reports discuss the geographical preferences of Millennials in relation to job selection preferences. Our team analyzed the moving trends of Millennials in both Ohio and the United States to determine what factors influence this decision. Collectively, our team concluded that in order to successfully recruit Millennials, companies must offer benefit packages that center around work-life balance. This entails not just highlighting what a job requires technically, but opportunities for leadership development, social activities outside of work, and more. To recruit this upcoming talent, companies need a holistic approach that convinces Millennials that working for their company creates a great life, not just a great professional career. Our team then created a mock website (www.smuckerrelocation.weebly.com) that features relocation information for prospective employees moving to Northeast Ohio. A pilot usability test and focus groups were conducted to analyze the site’s efficiency, functionality, and ease of use. This service was then pitched to J.M. Smucker Company employees for their review

Two-layer LMDS system architecture: DAVIC-based approach and analysis

Despite the growing interest for LMDS systems there have been only a few commercial implementations until now especially outside of the U.S.A. The use of hierarchical structure through two-layer networking has been even rarer. In many cases LMDS systems have strong advantages against their competitors to cover the last mile. In this article, we review and analyze the standards currently available and describe the European two-layer trial system developed in 1996-2000. We show why further development towards IP based LMDS is useful in the future. Most of our recommendations are based on results derived from the European Union supported research project CABSINET. It had the aim of demonstrating the viability of a 40 GHz cellular digital television system with a return channel to offer interactive services. Two systems were tested: a line of sight link using QPSK, and a non-line of sight with COFDM modulation scheme. In the RF-subsystems, the greatest difficulty of any viable LMDS system is to obtain a moderately low price for the user receiver, while fulfilling the hard OFDM requirements in terms of phase noise, stability and spectrum restrictions. Several options have been studied in order to design the subsystems with the smallest cost. This paper will present the architectures of the transmitters, nomadic terminals, and the design of the IF/RF subsystems for both types of modulations. The discussion is focused on system engineering and selections required in order to build a full two-layer LMDS system.This work has been supported in part by European Commission through the ACTS programme (CABSINET project).

Multihop Medium Access Control for WSNs: An Energy Analysis Model

<p>We present an energy analysis technique applicable to medium access control (MAC) and multihop communications. Furthermore, the technique&#39;s application gives insight on using multihop forwarding instead of single-hop communications. Using the technique, we perform an energy analysis of carrier-sense-multiple-access (CSMA-) based MAC protocols with sleeping schemes. Power constraints set by battery operation raise energy efficiency as the prime factor for wireless sensor networks. A detailed energy expenditure analysis of the physical, the link, and the network layers together can provide a basis for developing new energy-efficient wireless sensor networks. The presented technique provides a set of analytical tools for accomplishing this. With those tools, the energy impact of radio, MAC, and topology parameters on the network can be investigated. From the analysis, we extract key parameters of selected MAC protocols and show that some traditional mechanisms, such as binary exponential backoff, have inherent problems.</p
