A new algorithm for predicting building rooftop displacements in individual aerial photos utilizing the lens location at the time of photographing and the 3D coordinates of rooftops is proposed in this paper. Based on camera calibration and mathematical relationships, the algorithm will be implemented through unprocessed 1 foot resolution aerial photographs and an approximated rooftop model. Knowing the lens location at data acquisition, the camera calibration, and the 3D rooftop corner coordinates, the original 3D coordinates of the rooftops can be mathematically projected onto the 2D individual photo coordinates. By overlaying the projected rooftops over unprocessed photos, the algorithm will be evaluated. This algorithm can be used for evaluation of existing 3D rooftop models or object-based change detection, such as those used in individual building damage assessment after an earthquake or hurricane.

The worldwide Digital Signage market has been getting increasingly popular in recent years. Nevertheless, for service providers, the Digital Signage business is still not easy to manage and time-consuming to operate. In this paper, based on the GPS and wireless infrastructure, we present a mobile location-aware digital signage system (LDSS). Through the centralized system architecture, the applications for the Digital Signage can be expanded to various advertising vehicles including buses and other mobile advertising vehicles. Also, we present an advertisement recommendation algorithm, by which the advertisement can be broadcasted in the right markets more effectively. Evidenced by simulated experiments and analysis, compared with traditional region trigger advertising, sequential advertising and random advertising, our advertisement recommendation algorithm can effectively reach to the key target audiences in planned regions, while show excellent ability to differentiate markets in unplanned regions reaching to the target consumer groups as well. © 2010 IEEE.

Due to the increase of spectrum demand, the value of spectrum resource has been increased and efficiency of spectrum usage has been important issues in the wireless industry. Therefore recently, there have been many efforts on changing spectrum management framework based on the market mechanism. This research analyzes three different mechanisms as an alternative of secondary trading framework;a brokerage mechanism, auctions and a direct trading. As a consequence, this research suggests an optimal framework for the secondary use trading based on the in-depth simulations which consider different attributes by technical characteristics and market changes and investigate economic values and competition environments. ©2010 IEEE.

This paper reports on the second phase of a research project aimed at the development of an environmentally friendly noise barrier for urban freeways, also known as KMAK [1]. The concrete barrier, which has some unique capabilities to mitigate transportation noise, is made from recycled concrete (RC) aggregate and industrial by-products such as fly ash and reclaimed water. The current developmental work expands on a research project that resulted in a two-layer (2L) concrete barrier. Two prototypes of the 2L barrier were produced, followed by extensive acoustic testing and a number of simulations where standard timber and/or concrete barriers were substituted with KMAK barrier [2]. Current research investigates a variety of architectural finishes applied to the original KMAK barrier with the aim of improving its visual appearance and also fine-tuning its acoustic performance. The new three-layer (3L) barrier optimizes sound absorption in a frequency range characteristic similar to that of transportation noise, especially road traffic noise. Three major aspects related to the development of architectural finishes were considered;environmentally responsible materials, surface features, and production methods. The findings of the current investigation demonstrate that there is a positive correlation between surface features, percentage of perforation as well as depth of the architectural layer, and increased potential of the 3L barrier to mitigate transportation noise. On average, the addition of perforated architectural finish contributes to a 20% increase in sound absorption. The preliminary results also show that the sound absorbency of the 3L barrier can be better controlled and tuned to specific noise frequency than the 2L type. The visual appearance has been significantly improved with the addition of the architectural finish, which makes the barrier an attractive, feasible, and viable alternative to road barriers made from standard concrete or timber. © Chinese

Organizations that have adopted the principles of the Six Sigma methodology have become aware that once they have achieved the five sigma quality levels, the only way to progress further is to redesign their products or processes. This has led to the development of Design for Six Sigma (DFSS). Recently, DFSS has gained much popularity due to the widespread application of Six Sigma principles, particularly in new product development. This research employs the systematic view of the DFSS process and combines it with quality tools to improve the design quality of Original Design Manufacture (ODM) electronic products. A wireless communication company applying the DFSS methodology was analyzed, and an index of one-Year Return Rate (YRR) from TL 9000 Quality management System Requirements of the worldwide telecommunication industry was used to evaluate the measurable effect of product design quality. The average YRR result of an ODM product group employing the DFSS process was observed to be better than an Original Equipment Manufacture (OEM) product group without the DFSS process. Furthermore, its relative value can be improved up to 25 times or 1.12 sigma. By applying the DFSS methodology, the demands of customers can be further satisfied, and the specific needs of the customer are fulfilled.

According to a study conducted by J. D. Angrist (MIT) and colleagues1 involving 1,600 students at a large Canadian university (the equivalent of an American state university with heavily subsidized tuition), the combination of participation in (a) a scholarship program and (b) academic support services resulted in higher grade achievement and retention for females (but both males and females used support services and peer advising at higher rates), compared to groups of students who participated in either (a) or (b) but not both. A report by the Educational Policy Institute2 lists financial aid as one critical factor that affects the decision to pursue a college degree and success in degree attainment for minorities. This paper reports the progress of a persistence-to-graduation scholarship program funded under the National science Foundation Scholarships (NSF) in science, Technology, engineering, and Mathematics (S-STEM) program. We named our program YES (Young Entrepreneur and Scholar) scholarship program. The goal of YES is to enable academically talented, financially needy students to enter the workforce (Entrepreneurship Path) or to pursue a graduate degree (Research Path) following the completion of a baccalaureate degree in a targeted STEM discipline. This goal is facilitated through scholarships offered by the program to qualified student participants in the last two college years (maturing years - juniors and seniors), a mentorship program (faculty and industry mentors), and enhanced educational opportunities (Distinguished Speaker seminar series, Symposium, learning community). The program continues the efforts of and recruits from another NSF-funded program, science, Technology, engineering, and Mathematics Talent Expansion (STEP) program, which focuses on the first two student college years (early years- freshman and sophomore) and has been successful in retaining STEM students at significantly higher rates than academically similar STEM students at the

In this paper, the bullwhip effect in a two-stage supply chain with one supplier and two retailers is measured. The customer demand is assumed to be followed an AR(1) model and is forecasted at each retailer by using the minimum mean square error forecasting method. In addition, the retailers employ the base stock inventory policy. Among the findings of this research, it is interesting to note that the bullwhip effect in supply chains will be minimized as the retailers have the same market share. ©2010 IEEE.
