Full textAbstract:
This paper presents a concept for an SDRAM controller targeting video processing platforms with dynamically reconfigurable processing units (RPUs). A priority-arbitration algorithm provides the required QoS and supports high bit-rate data streaming of multiple clients. Conforming to common video data structures the controller organizes the memory in partitions, frames, lines, and pixels. The raised level of abstraction drastically reduces the complexity of clients' addressing logic. Its uniform interface structure facilitates instantiations in systems with various clients. In addition to SDRAM controllers for regular applications, special demands of reconfigurable platforms have to be satisfied. The aim of this work is to minimize the number of required bus macros leading to relaxed place and route constraints and reducing the number of critical design paths. A suitable interface protocol is presented, and fundamental implementation issues are outlined.

Background Patients in psychiatric wards typically have very limited access to individual psychological therapy. Inpatients often have significant time available, and an important transition back to everyday life to prepare for—but historically, there have been few trained therapists available on wards for the delivery of evidence-based therapy. Automated virtual reality (VR) therapy may be one route to increase the provision of powerful psychological treatments in psychiatric hospitals. The gameChange automated VR cognitive therapy is targeted at helping patients overcome anxious avoidance and re-engage in everyday situations (such as walking down the street, taking a bus, or going to a shop). This treatment target may fit well for many patients preparing for discharge. However, little is known about how VR therapy may be viewed in this setting. Objective The objectives of the study are to explore psychiatric hospital staff and patients’ initial expectations of VR therapy, to gather patient and staff views of an automated VR cognitive therapy (gameChange) after briefly experiencing it, and to identify potential differences across National Health Service (NHS) mental health trusts for implementation. Guided by an implementation framework, the knowledge gained from this study will be used to assess the feasibility of VR treatment adoption into psychiatric hospitals. Methods Focus groups will be conducted with NHS staff and patients in acute psychiatric wards at 5 NHS mental health trusts across England. Staff and patients will be interviewed in separate groups. Individual interviews will also be conducted when preferred by a participant. Within each of the 5 trusts, 1 to 2 wards will be visited. A total of 8-15 staff and patients per ward will be recruited, with a minimum total of 50 staff and patients recruited across all sites. Focus group questions have been derived from the nonadoption, abandonment, and challenges to the scale-up, spread, and sustainability (NASSS) framework. Focus groups will discuss expectations of VR therapy before participants are given the opportunity to briefly try the gameChange VR therapy. Questions will then focus on opinions about the therapy and investigate feasibility of adoption, with particular consideration given to site specific issues. A thematic analysis will be conducted. Results As of May 15, 2020, 1 patient focus group has been conducted. Conclusions The study will provide unique insight from patients and staff into the potential for implementing automated VR therapy in psychiatric wards. Perspectives will be captured both on the use of immersive technology hardware and therapy-specific issues in such settings. International Registered Report Identifier (IRRID) DERR1-10.2196/20300

Various field bus protocols come up with the development of technology, each device manufactures are using their own way to managing assets in their assets function managing systems, the shortage of this self-enclosed solution is self-evident. Users are looking forward to more and more functions realized by filed device, thus the devices linked into field bus are getting more and more complicated. To echo this needs, FDT/DTM technology is used in process of developing device managing system. FDT technology is one truly liberal technology, users could easily transfer device data into useful information, beyond the influence of their filed bus protocol, device vendor, as well as the device type, to realize supporting various field bus in one system.

Background Hand-foot skin reaction (HFSR) is a serious side effect induced by multiple-tyrosine kinase inhibitors (TKIs). HFSR can cause treatment interruption or decreased dosing. HFSR also markedly decreases quality of life and is associated with the therapeutic efficacy of multiple-TKIs. Therefore, the management and prevention of HFSR is an important issue; however, an effective method for its prevention has not been established. Specific ascorbic acid derivatives can reverse multiple-TKI-induced keratinocyte growth and pathological changes in vitro. Objective This study was designed to evaluate the safety of bis-glyceryl ascorbate (Amitose DGA), a novel, hydrosoluble, and moisturizing ascorbic acid derivative, in patients with renal cell carcinoma (RCC) receiving sunitinib therapy. This study was also designed to evaluate Amitose DGA’s preventive efficacy for sunitinib-induced HFSR. Methods This is a Phase I/II, single-center, uncontrolled, single-arm, open-label trial. We will recruit a total of 30 patients with RCC receiving sunitinib therapy, with a 2-week-on and 1-week-off schedule. The participants will apply Amitose DGA-containing cream over both palmar and plantar surfaces within two treatment cycles (ie, 6 weeks) of sunitinib in combination with a general moisturizing agent, in addition to standard-of-care processes. Safety assessments will include dermatological abnormalities, clinical laboratory tests, and incidence of adverse events. Efficacy assessments will include development of HFSR and therapeutic outcomes associated with sunitinib. Results Recruitment to the study began in August 2017 and is ongoing in Japan. To date, 21 subjects have been recruited. Study completion is expected in 2021. Conclusions This is the first clinical study of Amitose DGA-containing cream in patients with RCC who are receiving sunitinib therapy. The single-center, single-arm, open-label design was selected to maximize subject exposure and increase the likelihood of achieving our study endpoints. The results will provide valuable and preliminary evidence of the effects of Amitose DGA-containing cream on HFSR.

With the application of digital information technology and communication technology, industrial intelligence and integration also began to develop rapidly, and the importance of the research on bus communication in industrial control communication also increased. As the first international bus standard, PROFIBUS has been widely used in the field of industrial control; in recent years, it was mainly used to connect devices to the control layer and convert data through token transmission. Based on the understanding of the transmission mechanism of PROFIBUS fieldbus protocol, this article carries out a simulation study on its communication performance. Through analysis of the data link layer, changing the target token cycle time (high and low priority) and random setting each site message number, as well as the number of master station and slave station, how the main token latency and packet loss rate and efficiency of bus affect the change of performance parameters was observed. For multiple communication systems, the relationship between the address value on the main token ring and transport performance is found by experiments on the site address value on the main token ring and the target token cycle time value. Finally, the scheduling algorithm is applied to the communication scheduling of PROFIBUS fieldbus. The results confirm that the scheduling algorithm has better transmission efficiency than the traditional MAC media access protocol under the condition that the load rate does not exceed 100%, which makes up for the shortcomings of the original PROFIBUS bus system and makes the communication performance better.

In the design of CAN network system, as CAN bus topology will affect network performance and cost, it is important to optimize the network topology. This paper analyzes the CAN busload based on CAN protocol, calculates the upper limit of transmission message frames in a single CAN bus. As the amount of information on the bus is increasing, a single CAN bus cannot meet the communication requirements, we put forward dividing the network into multiple homogeneous segments via multi-objective optimization method, developing a genetic algorithm strategy and solving the problem in a MATLAB platform. Finally utilize the method to design a pure electric vehicle network topology.

This paper describes a research on The Flexible Bus Systems (FBS) using SMAC as a communication medium. The Flexible Bus System is a demand responsive transit (DRT) but it is more efficient and convenient in a sense that it entertains passengers demands and gives bus locations in real time. The real time synchronization of The Flexible Bus System makes it information rich and unique as compared to other DRTs. The Flexible Bus Systems is a system that can replace the Traditional Bus Systems with its flexibility and efficiency. This paper discusses the use of wireless technologies in The Flexible Bus Systems and how to make it more reliable using short range wireless technology SMAC protocol.

Full textAbstract:
In a System on a Chip (SoC), interconnect is the factor limiting Performance,
Power, Area and Schedule (PPAS). Distributed crossbar switches also called as
Switching Central Resources (SCR) are often used to implement high performance
interconnect in a SoC – Network on a Chip (NoC). Multiple issue bus protocols like AXI
(from ARM), VBUSM (from TI) are used in paths critical to the performance of the
whole chip. Experimental analysis of effects on PPAS by architectural modifications to
the SCRs is carried out, using synthesis tools and Texas Instruments (TI) in house power
estimation tools. The effects of scaling of SCR sizes are discussed in this report. These
results provide a quick means of estimation for architectural changes in the early design
phase. Apart from SCR design, the other major domain, which is a concern, is deadlocks.
Deadlocks are situations where the network resources are suspended waiting for each
other. In this report various kinds of deadlocks are classified and their respective mitigations in such networks are provided. These analyses are necessary to qualify
distributed SCR interconnect, which uses multiple issue protocols, across all scenarios of
transactions. The entire analysis in this report is carried out using a flagship product of
Texas Instruments. This ASIC SoC is a complex wireless base station developed in 2010-
2011, having 20 major cores. Since the parameters of crossbar switches with multiple
issue bus protocols are commonly used in SoCs across the semiconductor industry, this
reports provides us a strong basis for architectural/design selection and validation of all
such high performance device interconnects.
This report can be used as a seed for the development of an interface tool for
architects. For a given architecture, the tool suggests architectural modifications, and
reports deadlock situations. This new tool will aid architects to close design problems and
bring provide a competitive specification very early in the design cycle. A working
algorithm for the tool development is included in this report.<br>text

Work to date on negotiation protocols has focused almost exclusively on defining contracts consisting of one or a few independent issues and a relatively small number of possible contracts. Many real-world contracts, by contrast, are much more complex, consisting of multiple interdependent issues and intractably large contract spaces. This chapter describes a simulated annealing-based approach appropriate for negotiating such complex contracts that achieves near-optimal social welfare for negotiations with binary issue dependencies.

Informatics begins with organized data. This consists of creation of a structured approach to data classification and management. The implications of the terms data, information, and knowledge are understood to be a hierarchy of data complexity and interrelationships. Knowledge management is a key component of the information system. Knowledge management has multiple potential pitfalls. Errant and obsolete data are the most common issues. Guidelines change, and for a busy clinician, it is hard to keep track of the new changes. New indications for medications and procedures may be found. This new knowledge ultimately triggers changes to protocols and order sets, and these changes have to be made with appropriate speed as well as caution. Those in informatics make every decision on the basis of the best and most accurate information available at the time. Knowledge management needs to keep up.

In ad hoc networks, it is essential and desirable that running applications offer appropriate QoS. However, it becomes a challenge, especially in wireless sensor networks. This chapter concentrates on integrating the security aspect with those of disconnection because of the excessive utilization of a particular node. It is seen that in ad-hoc networks that it is possible to enhance the network lifetime significantly by incorporating the battery properties in the routing protocol. So that will increase the network performance while routing protocol integrates the security with battery to support the simulation results. These results show that adaptive DSR protocol maintains useful network lifetime in addition to improved performance. The chapter attempts to improve the overall QoS of the MANET. It is well known that QoS provisioning is an intricate and challenging issue in mobile ad hoc networks, especially when there are multiple QoS constraints.

Issues related to power system voltage levels have become increasingly important issue during last two and half decades. In power networks, low voltage situations may result in the loss of stability, voltage collapse and eventually to cascading power outages. Large number of incidents of voltage collapse has been reported in different countries across the globe. A simple indicator that has the potential in real time, i.e. L indicator has been used to find voltage profile at different switching condition and simulated using ANN in network reconfiguration for the improvement of voltage stability. A method for improving voltage stability in a power network comprising of multiple lines and switches has been suggested in this chapter based on system reconfiguration approach. ANN based fast and efficient methodology has been developed to obtain the optimum switching combination to achieve best voltage stability.

Avoiding from congestion and provision of reliable communication characterising the low energy consumption and high data rate is one of the momentous challenges at Media Access Control (MAC) layer. This become more difficult to achieve when there is energy constraint mixed with mobility of nodes. Same issue is addressed in this underlying paper. Here we have proposed a Time-Sharing Energy Efficient Congestion Control (TSEEC) technique for Mobile Wireless Sensor Networks. Time Division Multiple Access Protocol (TDMA) and Statistical Time Division Multiple Access Protocol (STDMA) are major constituents of this technique. These helps in conserving the energy by controlling the sleeping, waking up and listening states of sensor nodes. Load Based Allocation and Time Allocation Leister techniques further helps in conserving the network energy minimizing the network congestion. First mentioned technique is designed on the basis of STDMA Protocol and uses the sensor node information to dynamically assign the time slots while later said technique is does the job of mobility management of sensor node. This Time Allocation Leister techniques further comprises of Extricated Time Allocation (ETA), Shift Back Time Allocation (SBTA), and eScaped Time Allocation (STA) sub techniques for managing the joing and leaving of nodes to cluster and redundant\absence of data for communication respectively. To control the movement of mobile sensor nodes, we have also introduced mobility pattern as part of TSEEC that helps in making the protocol adaptive to traffic environment and to mobility as well. A comparitive analysis of proposed mechanism with SMAC is performed in NS2 along with mathematical anslysis by considering energy consumption, and packet deliver ratio as performance evaluation parameters. The results for the former outperforms to that of later. Moreover, comparative analysis of the proposed TSEEC with other MAC protocols is also presented.

Handling unpredictable attack vulnerabilities in self-proclaiming secure algorithms in WSNs is an issue. Vulnerabilities provide loop holes for adversary to barge in the privacy of the network. Attacks performed by the attacker can be active or passive. Adversary may listen to the sensitive information and exploit its confidentiality which is passive, or adversary may modify sensitive information being transferred over a WSN in case of active attacks. As Internet of things has basically three layers, middle-ware layer, Application layer, perceptron layer, most of the attacks are observed to happen at the perceptron layer in case of both wireless sensor network and RFID Tag implication Layer. Both are a major part of the perceptron layer that consist a small part of the IoT. Some of the major attack vulnerabilities are exploited by executing the attacks through certain flaws in the protocol that are difficult to identify and almost complex to identify in complicated bigger protocols. As most of the sensors are resource constrained in terms of memory, battery power, processing power, bandwidth and due to which implementation of complex cryptosystem to keep the data being transferred secure is a challenging phase. The three main objectives studied in this scenario are setting up the system, registering user and the sensors via multiple gateways. Generating a common key which can be used for a particular interaction session among user, gateway and the sensor network. In this paper, we address one or more of these objectives for some of the fundamental problems in authentication and mutual authentication phase of the WSN in IoT deployment. We prevent the leakage of sensitive information using the rabin cryptosystem to avoid attacks like Man-in-the-middle attack, sensor session key leakage, all session hi-jacking attack and sniffing attacks in which data is analyzed maliciously by the adversary. We also compare and prove the security of our protocol using proverif protocol verifier tool.

Wireless sensor networks act as an important role in the wireless communication area because of its properties, its intelligence, cheaper costs, and its smaller size. Multiple nodes are required for coperative communication, the low energy adaptive clustering hierarchy and LEACH-Vector Quantization are used for cluster and active cluster headformation. Further, Dijkstra Algorithm is used to find the shortest path between the active CHs and high-energy utilization, respectively. The main issue of inter-cluster communication is carried out in earlier work using LEACH and LEACH-V protocols. The chapter illustrates the LEACH-Vector Quantization Dijkstra protocol for shortest path active CH communication in a cooperative communication network. In the application point of view, LEACH-VD performs the lowest energy path. LEACH-V provides the intra-cluster communication between the cluster head, and using Dijkstra Algorithm, the minimum distance is calculated connecting the active cluster heads, which creates the shortest path results using an energy-efficient technique.

Full textAbstract:
Mobile adhoc network (MANET) is a collection of mobile devices which form a communication network with no pre-existing wiring or infrastructure. Multiple routing protocols have been developed for MANETs. As MANETs gain popularity, their need to support real time applications is growing as well. Quality of service(QoS) provisioning is becoming a critical issue in designing mobile adhoc networks due to the necessity of providing multimedia applications.These applications have stringent QoS requirements such as throughput, end-to-end delay, and energy. Due to dynamic topology and bandwidth constraint supporting QoS is a challenging task. QoS aware routing is an important building block for QoS support. The primary goal of the QoS aware protocol is to determine the path from source to destination that satisfies the QoS requirements. This article proposes a new energy and delay aware protocols called, energy and delay aware Adhoc On demand Distance Vector Routing (EDAODV) and energy and delay aware Dynamic Source Routing(EDDSR) based on extension of AODV and DSR. Simulation results show that the proposed protocols have a better performance than AODV and DSR in terms of energy, packet delivery ratio and end-to-end delay.

Mathematical models predict limit cycle oscillations (LCOs) in postural sway when the combination of neuromuscular time-delay and feedback gains are excessively large. LCOs have been observed in the standing posture of various populations known to have longer time-delays including concussed young adults and adults with neuromuscular impairment such as multiple sclerosis (MS) and Parkinsons disease (PD) but not healthy controls. However, the relationship between feedback gain and time-delay that leads to these LCOs has yet to be explored experimentally. In this study, we examine the relationship between the time-delay of healthy adults and the onset of LCOs under altered visual feedback. We find that there is an inversely proportional correlation between feedback gain and intrinsic neuromuscular time-delay for which LCOs arise. This finding has implications for the assessment and diagnosis of neuromuscular related balance issues through a simple and invasive protocol similar to that used in this study.

The behavior of suction piles that are installed by suction into soft Speswhite clay was investigated by model tests in a large geotechnical centrifuge. Many different placement and loading tests were carried out in similar soils, thereby providing a reliable method for evaluating the effects of selected parameters on pile response. Techniques and equipment were developed to prepare normally consolidated clay samples with a high degree of repetitiveness and to measure their characteristics in-flight (e.g., on-board movable Cone Penetrometer device – abbreviated CPT in this paper) in order to simulate deepwater offshore soil conditions. The CPT tests performed in-flight indicate that these objectives were achieved with the soil samples tested. Special devices were developed for this program to apply well-controlled vertical and inclined monotonic and cyclic loads. A well-controlled system was necessary to investigate sustained and cyclic loads for simulating environmental loading conditions on anchor pile moorings for floating production and drilling facilities, or on other facilities used in the storage and off-loading of oil and gas. In the test program, the capacity measured during monotonic loading served as a reference value for establishing a scale factor to be used in applying cyclic and sustained loading. A monotonic load test was always carried out before and after each cyclic or sustained load test in order to quantify any change in capacity due to a given loading event. Issues addressed in the program and discussed in this paper include the effect of suction installation methodologies on pile capacity, and the behavior of piles during inclined monotonic loading and cyclic loading due to simulated Gulf of Mexico hurricane events. Other issues were addressed in the program (e.g., simulated loop current events, effect of a sand layer on suction pile penetration) but are not included in this paper due to space limitations. A number of tests were performed for each loading condition and the data are judged to be robust because of the consistency of the results within the same tub when applying multiple loading sequences, and between tubs when applying a similar test protocol. The experimental data from the test program will be used to update ExxonMobil suction pile design practice, and to validate in-house and contractor numerical models.

Full textAbstract:
The FlexRay bus protocol recently adopted by the automotive industry provides both a time- and event-triggered communication paradigm, combined with communication via two independent channels, as well as optional bus-guardians in order to meet the bandwidth and reliability requirements by present and future emerging automotive applications. Despite the benefits and improvements, when compared to traditional bus systems (e.g., CAN), rare faults may still occur. In this regard, this paper presents an experimental investigation of the clique problem, where a FlexRay network gets partitioned into multiple functional domains. In such a scenario the nodes within a domain may still be able to communicate with each other, however, not across domain boundaries. As a result affected applications that rely on information from nodes of either domain may be impaired in their intended functionality as long as such a clique exists. Such an impairment affecting critical applications like the braking system may result in hazardous situations.
