Published: January 2015

A novel active contour model (ACM) for image segmentation, driven by both local and global image‐intensity information encoded by a self‐organising map (SOM), is proposed. Experimental results demonstrate the robustness of the proposed model to the contour initialisation and to the additive noise, when compared with the state‐of‐the‐art local and global ACMs. They also demonstrate its robustness to scene changes.
A novel transmission scheme to inter destination video synchronisation
Authors: Wu Jiyan , Cheng Bo , Shang Yanlei , Yuen Chau , Chen Junliang
Published: January 2015

Inter destination video synchronisation (IDVS) is a key technology in emerging interactive multimedia applications. It is essential to ensure the synchronous experiences of users in such applications. However, one inevitable barrier for IDVS is the packet transfer delay differences (PTDDs) among different destinations. Existing researches have tried to eliminate the side effects of PTDD passively and schedule the video packets in a ‘back‐to‐back’ fashion. In this paper, the authors propose to proactively leverage such differences to design a transmission scheme that enhances video quality while ensuring the synchronous arrival of packets. Based on the network measurements from a real multimedia conferencing system and the Planetlab, they find that the PTDD is between the ranges of 100–250 ms. Motivated by this observation, they propose a scheme named asynchronous departure for synchronous arrival (ADSA), which inserts intervals between consecutive packets according to the synchronisation reference. To prove the superiority of ADSA, they carry out analysis based on Gilbert loss model and continuous time Markov chain. They conduct performance evaluation through emulations in Exata and experimental results show that ADSA improves the video peak signal‐to‐noise ratio by up to 9.1 and 6.9 dB compared with existing latest and earliest schemes, respectively.

Ultra‐wideband (UWB) is a very attractive technology for innovative in‐car wireless communications requiring high data rates. A designated antenna, which presents a reflection coefficient (S11) matched band comparable to the band‐pass filter (BPF) normally required at the transducers, plays a positive contribution in this in‐car application and was validated for the scenario. The inherited BPF‐like response of the antenna relaxes the specification of the front‐end BPF components of the transceivers. The in‐car propagation channel was modelled and used to validate the BPF‐like antenna. For the modelling, a comprehensive set of well‐defined measurements (using a standard antenna) were used to set‐up the in‐car channel simulator and simulated results were used to validate the BPF‐like antenna. In addition, the performance of the UWB radio system is studied and the probability of errors over the communication channel compared using the standard and the BPF‐like antenna by predictions.
Statistical quality of service provisioning in multi‐user centralised networks
Authors: Efazati Sara , Azmi Paeiz
Published: January 2015

Statistical quality of service (QoS) provisioning is a performance metric that determine the user satisfaction as the main purpose of future wireless networks. Effective capacity (EC) is a valuable quantity which helps analysing delay QoS performance as the most popular QoS metric. In this study, the authors concentrate on characterising the delay QoS performance via the EC of uplink transmission mode of individual users in multiuser centralised networks in which the user's transmitted signals may interfere with each other. To reduce the computational complexity of finding EC, the authors first propose closed form expressions for the EC of each user, with or without considering the inter‐symbol interference (ISI). Then, two general algorithms are presented to clarify the relation of EC and QoS guarantee performance of a system in which the way of analysing QoS guarantee performance is explained step‐by‐step. By the use of these algorithms and the obtained closed form EC functions, the authors investigate the statistical delay QoS performance of individual users and the effects of channel conditions and ISI on their performance. The numerical results validate our analytical outcomes in deriving closed form equations and evaluate the offered schemes in characterising delay QoS performance.
Optimal resource allocation for cooperative orthogonal frequency division multiplexing‐based cognitive radio networks with imperfect spectrum sensing
Authors: Hao Wanming , Yang Showyi , Ning Bing , Hao Wanliang
Published: January 2015

This study investigates sensing‐based spectrum sharing access (SSSA) and sensing‐based spectrum opportunistic access (SSOA) schemes in cooperative orthogonal frequency division multiplexing (OFDM)‐based cognitive radio networks with imperfect spectrum sensing. The optimal resource allocation strategy, including sensing time and transmit power, is designed to maximise the ergodic throughput of the secondary system. For a two‐hop cooperative communication in the secondary system, the authors adopt the amplify‐and‐forward relay protocol and enable the source and relay to sense the state of the primary user jointly. To protect the PU effectively from harmful interference, they consider the average interference power constraint in each hop. The total average transmit power constraint of the source and relay is considered. Two simplified versions for the SSSA and SSOA schemes are employed because of the complexity of the problem. They then propose two algorithms that acquire the optimal sensing time and power allocation for both schemes. Finally, simulation results are presented to compare the performance of the two schemes.
Signal detection technique for asynchronous filtered multi‐tone modulation‐based mesh systems
Authors: Shin Seung‐Min , Choi Joo‐Hyung , Park Chang‐Hwan , Yang Won‐Young , Cho Yong‐Soo
Published: January 2015

In this study, the authors propose a signal detection technique of successive interference cancellation to reduce the effect of inter‐symbol interference (ISI), which is caused by the time difference of arrivals among distributed nodes in an asynchronous wireless mesh network based on filtered multi‐tone modulation. The proposed signal detection technique uses partial matrices of a transmission gain matrix to mitigate the ISI effect from the adjacent symbols. Under the assumption of perfect symbol time offset and channel estimation at each node, it is shown by simulation that the proposed technique can improve the bit error rate performance with lower complexity compared with the conventional technique.
Game‐theoretic energy trading network topology control for electric vehicles in mobile smart grid
Authors: Mondal Ayan , Misra Sudip
Published: January 2015

Existing works on energy trading consider different schemes for forming energy trading networks, which assume that each plug‐in hybrid electric vehicle (PHEV) is connected with a single micro‐grid. Consequently, in on‐peak hours, a PHEV obtains the requested energy during the allotted time slot by paying a higher price. Alternatively, the PHEV waits for a significant duration of time to get serviced until the on‐peak hour elapses. In this study, the authors propose that a PHEV may obtain energy from any of the available micro‐grids within a coalition instantaneously without paying higher price. In this work, the problem of energy trading network topology control (ENTRANT) for PHEVs is studied as a ‘multi‐leader multi‐follower Stackelberg game’. In this game, each PHEV acts as a leader, and decides the amount of energy to be requested to the selected micro‐grid. On the other hand, the micro‐grids act as followers, need to decide the price per unit energy. Using variational inequality, it is shown that the proposed scheme, ENTRANT, has generalised Nash equilibrium, which is also socially optimal. ENTRANT enables the PHEVs and the micro‐grids within a coalition to reach the equilibrium state, is evaluated theoretically, as well as through simulations.
Adverse Effect of Trauma on Neurologic Recovery for Patients with Cervical Ossification of the Posterior Longitudinal Ligament
Authors: Lee Soo Eon , Jahng Tae-Ahn , Kim Hyun-Jib
Published: January 2015

Study Design

Retrospective study.

Objective

Minor trauma, even from a simple fall, can often cause cervical myelopathy, necessitating surgery in elderly patients who may be unaware of their posterior longitudinal ligament ossification (OPLL). The aim of this study is to determine the influence of trauma on the neurologic course in patients who have undergone surgery for cervical OPLL.

Methods

Patients who underwent surgery due to OPLL were divided by trauma history and compared (34 in the trauma group; 70 in the nontrauma group).

Results

Ground falls were the most common type of trauma (20 patients, low-energy injuries), but 23 patients developed new symptoms after a trauma. Although the symptom duration (17.68 months) was shorter, the Japanese Orthopedic Association (JOA) score and the Nurick scale showed lower values in the trauma group. Trauma histories led patients to earlier hospital visits. Initial JOA scores were associated with a good recovery status upon the last follow-up in both the groups. The narrowest diameter of the spinal canal showed different radiologic parameters: 5.78 mm in the trauma group and 6.52 mm in the nontrauma group.

Conclusion

Minor trauma can cause the unexpected development of new symptoms in patients unaware of cervical OPLL. Patients with a history of trauma had lower initial JOA scores and showed a narrower spinal canal compared with a nontrauma group. The initial JOA scores were correlated with a good recovery status upon the last follow-up.
gLISA: geosynchronous laser interferometer space antenna concepts with off-the-shelf satellites
Authors: Tinto M. , DeBra D. , Buchman S. , Tilley S.
Published: January 2015

We discuss two geosynchronous gravitational wave (GW) mission concepts, which we generically name gLISA. One relies on the science instrument hosting program onboard geostationary commercial satellites, while the other takes advantage of recent developments in the aerospace industry that result in dramatic satellite and launching vehicle cost reductions for a dedicated geosynchronous mission. To achieve the required level of disturbance free-fall onboard these large and heavy platforms, we propose a new drag-free system, which we have named “two-stage” drag-free. It incorporates the Modular Gravitational Reference Sensor (developed at Stanford University) and does not rely on the use of μN thrusters. Although both mission concepts are characterized by different technical and programmatic challenges, individually they could be flown and operated at a cost significantly lower than those of previously envisioned gravitational wave missions, and in the year 2015 we will perform at JPL a detailed selecting mission analysis.

Published: January 2015

The problem of demixing in the Asakura–Oosawa colloid-polymer model is considered. The critical constants are computed using truncated virial expansions up to fifth order. While the exact analytical results for the second and third virial coefficients are known for any size ratio, analytical results for the fourth virial coefficient are provided here, and fifth virial coefficients are obtained numerically for particular size ratios using standard Monte Carlo techniques. We have computed the critical constants by successively considering the truncated virial series up to the second, third, fourth, and fifth virial coefficients. The results for the critical colloid and (reservoir) polymer packing fractions are compared with those that follow from available Monte Carlo simulations in the grand canonical ensemble. Limitations and perspectives of this approach are pointed out.

Published: January 2015

Exact expressions are derived for the pair and three-body hydrodynamic interactions between a sphere and a number of small particles immersed in a viscous incompressible fluid. The analysis is based on the Stokes equations of low Reynolds number hydrodynamics. The results follow by a combination of the solutions for flow about a sphere with no-slip boundary condition derived by Stokes and Kirchhoff and the result derived by Oseen for the Green tensor of Stokes equations in the presence of a fixed sphere.
