Abstract:
Patients suffering from intestinal failure present unique and difficult challenges to the transplant team. Augmenting the need for interdisciplinary teamwork is the higher incidence of death on the intestinal transplant waiting list. Successful management of this population requires an interdisciplinary approach at each stage of care, beginning with evaluation and continuing through discharge and lifetime management. A close relationship between patients, their caregivers, and all members of the transplant team is an essential component to successful lifetime management. Open communication between team members and unlimited accessibility to each other enables work flow to be managed efficiently, and enables the provision of optimal care. In this article, we describe the functions of the nonphysician clinical personnel needed to manage the intestinal transplant patient—beginning at the evaluation through lifetime follow-up care. The goal of each professional is the same: to restore the patient to the best quality of life possible.

Abstract:
Pneumatic linear peristaltic actuators can offer some potential advantages when compared with conventional ones. The low cost, virtually unlimited stroke and easy implementation of curved motion profiles are among those benefits. On the downside, these actuators suffer high mechanical stress that can lead to short service life and increased leakage among chambers during the actuator lifetime. One way to cope with this problem is to impose the force—instead of the displacement—between rollers, as this has been shown to improve the endurance of the hose while reducing leakage during the actuator lifetime. This paper presents closed control loop results using such a setup. Previous studies with linear peristaltic actuators have revealed that, although it is possible to reach zero steady state error to constant references with closed loop control, the dynamic response obtained is very slow. This paper is mainly focused on this topic, namely on the development of several control laws to improve the dynamic performance of the system while avoiding limit cycles. The new developed control law leads to an average time of 1.67 s to reach a 0.1 mm error band in an experiment consisting of a series of 16 steps ranging from 0.02 to 0.32 m in amplitude.

Abstract:
The energy limitation of wireless sensors limits the lifetime of the traditional wireless sensor networks. The <b>Battery-Free Sensor Network (BF-WSN)</b> is a new network architecture proposed in recent years to address the limitation of wireless sensor networks. In a BF-WSN, the battery-free node can harvest energy from the ambient environment, and thus the lifetime of a BF-WSN is unlimited in terms of energy. The coverage quality is an important measurement of BF-WSNs. Considering the specific features of BF-WSNs, we propose a new deployment concept for BF-WSNs, named <i>Joint Deployment</i>. It aims to determine the locations and working schedules of sensor nodes to maximize network coverage quality. Based on the joint deployment concept, we propose a new deployment problem of battery-free sensor nodes. We prove that this problem is at least NP-Hard. We also analyze the upper bound of this problem. Furthermore, we propose an approximated algorithm to solve this problem and analyze the time complexity and the ratio bound of the algorithm. Extensive simulations are carried out to examine the performance of the proposed algorithm. The simulation results show that the algorithm is efficient and effective.

Abstract:
With the development of wireless sensor networks, many building energy management systems are getting to adopt wireless sensor network as their communication infrastructure. However, the existing wireless sensor network protocols cannot satisfy the energy-saving demand of building energy management systems. Considering the characteristics of the building energy management system wireless sensor networks, a novel energy-efficient routing scheme is proposed called relay participated–new-type building energy management system. Nodes in the building energy management system wireless sensor networks are divided into two types: energy-limited nodes (battery powered) and energy-unlimited nodes (main powered, solar charger, or heat energy powered). Relay participated–new-type building energy management system allows energy-unlimited nodes to temporarily receive packets that are routed to a nearby energy-limited nodes. In this way, time synchronization for low-power sleep at media access control layer is no longer required, which reduces the delay and control overhead at media access control layer dramatically. Relay participated–new-type building energy management system reduces energy usage of energy-limited nodes and extend the lifetime of wireless sensor networks in new-type building energy management systems. Simulation results show that the relay participated–new-type building energy management system protocol significantly improves energy efficiency of limited energy nodes and reduces latency as compared to ad hoc on-demand distance vector–sensor medium access control and low-energy adaptive clustering hierarchy.

Abstract:
RFID is a rapidly developing technology of wireless communication and identification mostly used in supply chain systems, logistic and access control. Nowadays attempts to transfer this technology to other applications are carried out. This paper presents review of global researches performed last years, on application of RFID technology to tasks connected with wireless passive sensing in Structural Health Monitoring, with additional overview of works conducted in this subject by the authors. Sensors based on this technology require neither battery nor wire. It could be interrogated from distance, its lifetime is almost unlimited. Investigations, focused both on using RFID transponder as a sensing element, as well as, using antenna as a energy harvesting part that could power the sensor circuit, are mentioned. Performed studies show, that despite problems connected with using high frequencies, described wireless sensors should be useful for SHM tasks.

Abstract:
Congestion control is one of the key research topics in relation to the routing algorithms of wireless sensor networks (WSNs). In this paper, we propose a congestion-aware routing algorithm (CARA) for unlimited-lifetime wireless sensor networks by integrating the geographic distance and traffic load of sensor nodes. The algorithm takes alleviating congestion as the primary purpose and considers the traffic of the node itself and local network traffic. According to the geographic distance between nodes, CARA defines four decision parameters (node load factor, forward rate, cache remaining rate, and forward average cache remaining rate), selecting the best node as the next-hop through the multi-attribute decision-making method. Compared with the two existing algorithms for congestion control, our simulation results suggest that the CARA algorithm alleviates network congestion and meets reasonable network delay and energy consumption requirements.

Abstract:
Source-free equations of nonlinear electrodynamics minimally coupled to gravity admit regular axially symmetric asymptotically Kerr-Newman solutions which describe charged rotating black holes and electromagnetic spinning solitons (lumps). Asymptotic analysis of solutions shows, for both black holes and solitons, the existence of de Sitter vacuum interior which has the properties of a perfect conductor and ideal diamagnetic and displays superconducting behaviour which can be responsible for practically unlimited lifetime of the electron. Superconducting current flows on the equatorial ring replacing the Kerr ring singularity of the Kerr-Newman geometry. Interior de Sitter vacuum supplies the electron with the finite positive electromagnetic mass related to the interior de Sitter vacuum of the electroweak scale and to breaking of space-time symmetry, which allows explaining the mass-square differences for neutrino and the appearance of the minimal length scale in the annihilation reaction e+e-→γγ(γ).

Target coverage is an important issue of wireless sensor networks and has been received a lot of attention in the past few years. Recent studies have shown that energy harvesting is essential for sensor networks in some specific situations, because it is costly and hard to maintain the wireless networks if the sensors’ battery was frequently replaced. As a result, this paper addresses the target coverage problem for the solar-powered sensor networks, and this paper also consider that the POIs would have the different importance since they are distributed in different places over the network environment. In the considered WSN, each sensor can either recharge its battery or monitor the point of interest (POI) at the same time. To make the WSN perpetual and balance the quality of target monitoring, this paper proposes two efficient sensor activation schedules while guarantee the target coverage and the POIs which with the higher importance will have the higher QoM. In addition, the proposed activation schedules can guarantee that all POIs can be well monitored even during the nighttime. In the performance study, it presents that the proposed mechanism outperforms the existing mechanisms in term of QoM balance index of POIs, decrease the range of the POIs’ QoM.

Abstract:
Market requirements for the gas turbine business have significantly changed in the last years due to a stronger demand for lifecycle cost optimization and the increased share of renewable energy. Gas turbine technology development focus must be adapted accordingly. The need for increased efficiency throughout the operation range, particularly at part load, requires more accurate and faster design methods and prediction capabilities. At the same time, technologies must be developed and validated to increased flexibility in many areas, including unlimited operation range (without aerodynamic, mechanical or emission constraints), fuel types and composition, and faster ramp up rates (despite the increased thermal stress to gas turbine components) to stabilize the grid and to compensate for intermittent renewable power generation. Further lifecycle optimization counts on new technologies in reconditioning, lifetime monitoring and improved lifetime prediction. This paper provides an overview of the recent research and development activities, the approach to bring them into a product and the resulting trend in Alstom gas turbine technologies.

Abstract:
Articular cartilage is the primary compressive load bearing soft tissue in diarthrodial joints. While the tissue can function remarkably well in a demanding environment over a lifetime of use, focal defects and other trauma can initiate progressive degeneration. Cartilage tissue engineering approaches have been developed with the goal of forming biologic replacement materials with functional mechanical properties [1]. While chondrocytes are a popular cell source for such approaches, and can produce constructs with near-native functional properties [2], mesenchymal stem cells (MSCs) derived from bone marrow have emerged as an attractive alternative cell type. MSCs are multi-potent and easy to expand, and so are available in a nearly unlimited supply, and in an autologous fashion. While MSCs can undergo functional chondrogenesis in a variety of 3D contexts [3], we are particularly interested in the translational capacity of hyaluronic acid (HA). Hydrogels formed from this natural constituent of the cartilage extracellular matrix provide a biologically relevant interface for encapsulated cells and gel properties are readily tunable [4, 5]. Indeed, using a methacrylated (and so photo-crosslinkable) HA macromer, we have optimized gel formation and functional matrix production by MSCs with variations in both macromer (1%, [5]) and MSC (∼60 million cells/mL, [6]) concentration, consistently producing cartilage-like constructs with near native compressive properties. Additionally, we have reported that transient exposure of TGF-β3 (for three weeks) to MSCs in agarose constructs at a high-density induced a stable chondrogenic phenotype, with functional properties at six weeks greater than continual exposure to this pro-chondrogenic factor [7]. Transient exposure presents an interesting paradigm with clinical relevance, in vivo defect filling will require robust maturation of the engineered tissue driven by TGF-β3 delivered from the material itself in a controlled and sustained fashion. The purpose of this study was to determine the minimal TGF-β3 dosage and duration of exposure required to promote the most robust chondrogenesis and functional maturation of MSCs in this HA hydrogel system.
