Home NodeBs (HNB)s can be operated in a fullyclosed manner (in which only user equipment (UEs) within a closed subscriber group (CSG) are permitted to connect), a fully-open manner (in which access can potentially be granted to any nearby mobile station), or somewhere in between. An additional option is "hybrid" HNBs, in which a portion of the HNB resources are reserved for exclusive use of the CSG, and the remaining resources are allocated in an open manner. The relationship between access policy and the performance of the overall network is one of the most interesting open questions related to HNB deployment. The present paper explores the relationship between HNB access and quality of service with specific attention to the differences between HSDPA, HSUPA, and the relative mix of traffic types.

Palpation is a traditional method for diagnosis that uses the sense of touch. Due to its subj ective nature, results from palpation are not always accurate andlor consistent. Therefore in order to enable a consistent and quantitative analysis by palpation, we propose this diagnostic by a novel device called the Haptic Lens. Considering the richness of parameters in the cardiac pressure pulse, we focus on developing a quantitative method for measuring arterial pressure pulse parameters using the Haptic Lens. We develop algorithms that enable accurate measurements of arterial pulse parameters. To demonstrate the efficacy of our approach and the ease of learning this method we used this device to measure arterial pulse parameters on 10 individuals.

Abstract-We examine the scheduling problem in the context of heterogeneous cellular networks in the presence of mobility. We demonstrate that the QoS for users in a cellular network can be optimized using an interference-aware approach that is most effective at low Doppler frequency scenarios or a channel-aware approach that is most effective at higher low Doppler frequency scenarios.Among the most recent products introduced to the quickly evolving cellular market are devices called "femtocells", also known as "Home Node B" s in some contexts. Femtocells act similarly to regular base stations (BSs) in a cellular network, with the main exception that they use internet connections within their deployment area to connect to the cellular network. Low cost and low power consumption make femtocells attractive alternatives to the deployment of larger BSs in areas where demand is low or the cost of new BS deployments is high.The present paper focuses on the scheduling of data packets-specifically in the uplink-in a heterogeneous cellular network consisting of both macrocells and femtocells. The significance of this problem in the case of such networks is the limitation in the connectivity between the femtocells and the provider's network. Such limitations can include high latencies and relatively low data rates, which make operations such as soft hand-offs and fast synchronization impossible to achieve. Hence, what is needed is a scheduling approach that utilizes minimal data overhead and has low latency requirements.Scheduling in general has been widely studied in topics such as task assignment problems in operations research (see for example [1]), or scheduling of parallel applications in multiprocessor networks [2]. In [3] a taxonomy of various scheduling algorithms is presented. In the field of cellular packet data networks several studies have been performed. A fairness criterion introduced by [4] referred to as proportionally fair scheduling is a well known and widely deployed mechanism. In [5] it is shown that proportionally fair scheduling converges under various conditions to the solution of a logsum optimization criterion. In [6], [7], and [8] generalized versions of the proportionally fair optimization criteria are considered.The uplink scheduling algorithm presented here is based on simulated annealing, which was first proposed as an optimization method in [9]. Simulated annealing is an iterative optimization technique that has proven to be effective in solving general combinatorial optimization problems. In previous work, simulated annealing has been applied in a wide range of applications including scheduling in parallel systems [10], [11], [12].In this work, we present a unique application of simulated annealing in the context of interference aware uplink packet scheduling in a cellular network. Results are presented that support its utility in the developed system framework, along with a foundation for the analysis of the optimization and necessary conditions for convergence of the proposed algorithm.Our...
