Interprocessor communication (PC) overheads have emerged as the major performance limitation in parallel processing systems, due to the transmission delays, synchronization overheads, and conflicts for shared communication resources created by data exchange. Accounting for these overheads is essential for attaining efficient hardware utilization. This(More)
The tremendous growth in wireless LANs has generated interest in technologies that provide higher data rates and greater system capacities. The IEEE 802.11a [1] standard, based on coded OFDM modulation [2,3], provides nearly five times the data rate and as much as ten times the overall system capacity as current 802.11b wireless LAN systems.

M to extend the economic lives of products—such as remanufacturing carried out by closed-loop supply chains—are receiving increased attention because of various economic and regulatory factors. In this paper, we examine drivers of price differentials between new and remanufactured products using data on purchases made on eBay. Our analysis shows that seller(More)
Extended Producer Responsibility (EPR) legislation focuses on the life-cycle environmental performance of products and has significant implications for management theory and practice. In this paper, we examine the influence of EPR policy parameters on product design and coordination incentives in a durable product supply chain. We model a manufacturer(More)
We investigate the implications of collective and individual producer responsibility (CPR and IPR, respectively) models of product take-back laws for e-waste on manufacturers’ design for product recovery (DfR) choices and profits, and on consumer surplus in the presence of product competition. We show that IPR offers superior DfR incentives as compared to(More)
Accelerometer and gyroscope sensors in smart phones capture the dynamics of human gait that can be matched to arrive at identity authentication measures of the person carrying the phone. Any such matching method has to take into account the reality that the phone may be placed at uncontrolled orientations with respect to the human body. In this paper, we(More)
This work investigates the suitability of medium-grained meeting behaviors, namely, speaking time and social attention, for automatic classification of the Extraversion personality trait. Experimental results confirm that these behaviors are indeed effective for the automatic detection of Extraversion. The main findings of our study are that: 1) Speaking(More)
