EVALUATING CHANNEL-FORMING DISCHARGES: A STUDY OF LARGE RIVERS IN OHIO

Measured data were used to evaluate whether bankfull discharges were related to effective discharges for large rivers in Ohio. The frequency and sediment transport associated with these channel-forming discharges was also examined. Rural watersheds in the Midwest region of the U.S. are dominated by agricultural land uses that incorporate subsurface drainage improvements. Bankfull discharges were determined by measuring fluvial features at each USGS gage and then relating these features to the rating curve and historic daily discharge data for each gage. Effective discharges were determined by using suspended sediment data obtained at the gages, the Wolman-Miller method for calculating geomorphic work, and bin sizes based on stage intervals to group sediment and discharge data. There was good agreement between the effective discharge and bankfull discharge estimates. Bankfull and effective discharges were primarily related to flows that transported the middle 50% of the total sediment load. Recurrence intervals of the bankfull and effective discharges ranged from 0.3 to 1.4 years. These recurrence intervals are more frequent than generally reported in the literature. The duration of daily discharges that equaled or exceeded the channel-forming discharge ranged from 1 to 24 days annually, with mean values of 9 and 11 days for the bankfull discharge and effective discharge, respectively. Common methods for determining the recurrence interval are inadequate for frequent channel-forming discharges, and better insight is obtained by determining the number of days on which these flows are exceeded annually.
Experimental Evaluation of Synchronisation in Footbridges due to Crowd Density

Synchronisation of movements of pedestrians implies a significant increase of the applied loads, and this has been appointed as the cause of excessive vibration in some footbridges. Experimental results on this phenomenon are scarce to support the development of design load models. Two aspects have been appointed as related to the phenomenon of synchronisation: interaction between pedestrians and structure (lock-in effect) and densification. In this paper, an experimental investigation of the potential synchronisation among pedestrians while walking across a prototype footbridge is presented, focusing on the contribution of densification. An additional walking test in a 25 m long corridor was included to evaluate the effect of the path length. In the footbridge, three tests with different pedestrian densities were carried out. The tests were filmed by a video camera and the processing of the images enabled the phase differences among the movement of pedestrians to be determined in both vertical and lateral (transverse) directions, by capturing the lateral movement of each pedestrian's head. The pacing rates of pedestrians walking in groups of varied densities were also determined. Synchronisation was not observed in spontaneous walking in either of the analysed directions (vertical and lateral) for densities up to 0,9 pedestrians/m2. The results presented may be useful for the development of crowd load models for footbridges. However, further tests with higher densities and, ideally, longer pedestrian paths would be necessary to completely clarify the phenomenon.
Development of ultra-stable laser sources and long-distance optical link via telecommunication networks

The transfer of ultra-stable frequencies between distant laboratories is required by many applications in time and frequency metrology, fundamental physics, particle accelerators and astrophysics. This thesis describes the development of ultra-stable optical links over distances from 86 km to 300 km. The long-term objective is to connect the main European National Metrology Institutes with optical links extending up to 1000 km. The optical link is based on the transfer of the optical phase of an ultra-stable laser emitting light of wavelength 1542 nm through an optical fiber of the telecommunication network. For that purpose, ultra-stable cavity-stabilized lasers and fiber-stabilized lasers have been developed. The fractional instability of cavity-stabilized laser is approximately 10-15 at 1s integration time. The fiber-stabilized lasers are robust, compact, simple, tunable and their frequency noise is comparable to that of the cavity-stabilized laser for Fourier frequencies higher than a few tens of Hertz. Optical links were first demonstrated on 86 km and 172 km using dedicated fibers connecting the laboratories LNE-SYRTE and LPL. Fractional frequency instability in the range of or below 10-19 at 104 s integration time has been obtained. For larger distances, the ultra-stable laser signal is transferred on the Internet network simultaneously with the data traffic but on a dedicated frequency channel, using wavelength division multiplexing. Multiplexed links were demonstrated over distances up to 300 km, with fractional frequency instabilities at the same level or better than with dedicated fibers.
Serum Lipids and Lipoproteins

Serum lipids and lipoprotein cholesterol fractions were examined in a newborn cohort that was followed from birth to 7 years of age. Although white and female infants had higher cord blood levels of high-density lipoprotein cholesterol (HDL-C) than did black and male infants, respectively, these differences did not persist throughout early childhood. Mean levels of all serum lipids and lipoproteins increased greatly in the first 6 months of life, and by 2 years of age, levels approached those seen in adolescents. Infants consuming cow's milk had higher 6-month levels of serum total cholesterol and low-density lipoprotein cholesterol than did formula-fed infants. However, milk source in infancy did not significantly influence total cholesterol or low-density lipoprotein cholesterol levels at age 7 years. Serum lipid and lipoprotein levels at age 7 years were associated with previously measured levels as early as 6 months of age, and infants with unfavorable levels were likely to have similar adverse levels at 7 years of age. In addition, increases in obesity between 6 months and 7 years of age were positively associated with increases in levels of serum triglycerides. These results suggest that certain persons at increased risk for cardiovascular disease can be identified in infancy.
Combining scoring method and fuzzy expert systems approach to supplier assessment: a case study

Very often, manufacturing companies have been faced with the problem of assessment and selection of suppliers for their product development. Some methods and techniques have been developed to assist these companies in performing the assessment. However, these methods and techniques lack tge capability to deal with the instrumental and conceptual uncertainties that are involved in the supplier assessment and selection. Fuzzy expert system is an alternative approach from which the heuristics and knowledge of supplier assessment can be captured and the impreciseness and uncertainties due to the human subjectivity, that are common in the process of the supplier assessment, can be handled. In this paper, a combined scoring method with fuzzy expert systems approach is introduced to perform the supplier assessment. With the use of the fuzzy concept, the error due to human judgement in the scoring method could be minimized. First, current methods and techniques of supplier assessment are reviewed in this paper. There follows the description of a case study of combined scoring method and fuzzy expert systems approach to supplier assessment. Some results of the prototype system trial‐run are discussed in the final part of this paper.

An effective data transmission scheme based on IoT system in opportunistic social networks

With the advent of the era of Big Data, users are increasingly demanding network bandwidth and data storage in the Internet of Things (IoT) system. While current research on the opportunistic social network does not take the redundant influence of high‐speed data transmission into account, which leads to problems such as lower delivery ratio, we present an effective data transmission scheme based on IoT system (EDTS). To divide the community, which consists of devices with relatively close connections, we measure the social relationship of nodes by quantifying the remaining cache, social relation, and interest similarity in opportunistic social networks. An efficient strategy is designed in this paper to update the community by analyzing the change of edge weights between two nodes in the community, deciding whether the community should be further divided, and whether the nodes should join the larger community. The proposed scheme also involves data transmission methods based on community, which involve inter‐community forwarding and intra‐community forwarding. Simulation results show that EDTS outperforms other comparative algorithms with regard to average delivery ratio, end‐to‐end delay, and routing overhead.
Field failure database of CNC lathes

To assess and improve the reliability of computerized numerical control (CNC) lathes, it is essential to collect field failure information throughout the products’ life and perform analysis on these data. This paper describes the collection of field failure data, codification of data and establishment of the field failure database for CNC lathes and gives some examples of the kind of analysis possible when sufficient data have been collected and the database has been accrued.
Target racking with glint noise

In tracking targets, there can be an uncertainty associated with the measurements in addition to their inaccuracy, which is usually modeled by aDditive Gaussian noise. However, the Gaussian modeling of the noise may not be true. Noise can be non-Gaussian. The non-Gaussian noise arising in a radar system is known as glint noise. The distribution of glint noise is long tailed and will seriously affect the tracking performance. An algorithm is developed which can significantly improve the tracking performance when glint noise is present. >
The frequency offset estimation algorithm for DBO-CSS (第21回 回路とシステム軽井沢ワークショップ論文集) -- (インタラクティブセッション)

In this paper, we propose a new frequency offset estimation algorithm for DBO-CSS which is a standard for wireless personal area network (WPAN). In DBO-CSS, there can be several integer multiples of 2π in the phase rotation caused by the frequency offset because of the long time difference between the samples of differential relation and the high permissible frequency offset of the crystal oscillators between the transmitter and the receiver. In this paper, we propose an estimation algorithm by using the relationships of each sub-chirp signals to find the integer part without phase ambiguity.
High-dose cervical mobilization to improve central sensitization for a patient with post-fusion neck pain

ABSTRACT Background Few studies have addressed the appropriate joint mobilization dosage for neck pain. Furthermore, the efficacy of manual therapy in patients with post-spinal fusion neck pain is unreported. Case Description A 63-year-old man with a 2-year history of unresolved neck pain post-cervical fusion presented to therapy with an exacerbation of neck and left-shoulder pain. The patient presented with cervical impairments of intervertebral hypo-mobility above and below the fusion site. He exhibited a high Numeric Pain Rating Scale (NPRS) score of 8/10 related to his neck pain. Additionally, he demonstrated marked loss of cervical mobility. Indicators of central sensitization were present, including both hyperalgesia and allodynia. High-dose cervical joint mobilization was applied for durations of up to 10 minutes. Corrective exercises were added to improve muscle strength and endurance. Treatment was applied for 12 sessions over 4 months. Outcomes At the time of discharge, this patient reported a full recovery of neck function. This treatment reduced pain, improved passive joint accessory motion, and restored upper quarter function. The patient demonstrated a 33-point improvement in his Neck Disability Index (NDI) score and his pain was reduced to 0–1/10 on the NPRS. Markers of central sensitization were resolved. Intervertebral passive accessory joint mobility was pain free in addition to concurrent restoration of functional mobility. Conclusion A paucity of evidence exists for appropriate dosage with manual therapy interventions. This case report demonstrates marked improvement of pain and function with the use of high-dose joint mobilization. Improved cervical accessory joint mobility and central pain modulation were achieved with high-dose joint mobilization.
Radio Channel Capacity with Directivity Control of Antenna Beams in Multipath Propagation Environment

The basic technology that will determine the expansion of the technical capabilities of fifth generation cellular systems is a massive multiple-input-multiple-output. Therefore, assessing the influence of the antenna beam orientations on the radio channel capacity is very significant. In this case, the effects of mismatching the antenna beam directions are crucial. In this paper, the methodology for evaluating changes in the received signal power level due to beam misalignment for the transmitting and receiving antenna systems is presented. The quantitative assessment of this issue is presented based on simulation studies carried out for an exemplary propagation scenario. For non-line-of-sight (NLOS) conditions, it is shown that the optimal selection of the transmitting and receiving beam directions may ensure an increase in the level of the received signal by several decibels in relation to the coaxial position of the beams. The developed methodology makes it possible to analyze changes in the radio channel capacity versus the signal-to-noise ratio and distance between the transmitter and receiver at optimal and coaxial orientations of antenna beams for various propagation scenarios, considering NLOS conditions. In the paper, the influence of the directional antenna use and their direction choices on the channel capacity versus SNR and the distance between the transmitter and receiver is shown.
The use of Mobile Phones in Strengthening Health and Demographic Data Collection by Community key Informants : Experiences from the Kintampo Health and Demographic Surveillance System

Identification and reporting of vital events such as births and deaths remain a challenge within communities in low- and middle-income countries (LMICs). LMICs are recently experiencing high mobile phone penetration. This study, therefore, explored the feasibility of Community Key Informants (CKIs) using mobile phone technology to improve reporting of vital events at the community level. Sixty CKIs were purposively sampled from the Kintampo Health and Demographic Surveillance System (KHDSS) setting based on mobile phone ownership. CKIs were grouped into an intervention and a control group. The intervention arm was provided with mobile phone air time to report vital events that occurred in their communities. The control group used the routine system of reporting in the KHDSS. The number of vital events reported by CKIs increased at the end line compared to baseline: (pregnancy: 40.25% to 72.80%; birth: 56.52% to 69.80%; deaths: 33.33% to 68.60%). The time interval between event identification and reporting was much shorter for the intervention group at the end line compared to baseline: (Intervention: 95.06 days to 31.35 days, Control: 87.54 days to 80.57 days). This study demonstrated the feasibility of CKIs using a mobile phone in reporting vital events more timely and effectively.

An Approach Based on VR to Design Industrial Human-Robot Collaborative Workstations

This paper presents an integrated approach for the design of human-robot collaborative workstations in industrial shop floors. In particular, the paper presents how to use virtual reality (VR) technologies to support designers in the creation of interactive workstation prototypes and in early validation of design outcomes. VR allows designers to consider and evaluate in advance the overall user experience, adopting a user-centered perspective. The proposed approach relies on two levels: the first allows designers to have an automatic generation and organization of the workstation physical layout in VR, starting from a conceptual description of its functionalities and required tools; the second aims at supporting designers during the design of Human-Machine Interfaces (HMIs) by interaction mapping, HMI prototyping and testing in VR. The proposed approach has been applied on two realistic industrial case studies related to the design of an intensive warehouse and a collaborative assembly workstation for automotive industry, respectively. The two case studies demonstrate how the approach is suited for early prototyping of complex environments and human-machine interactions by taking into account the user experience from the early phases of design.
UC3855A/B High Performance Power Factor Preregulator

The trend in power converters is towards increasingly higher power densities. Usually, the method to achieve this is to increase the switching frequency, which allows a reduction in the filter component’s size. Raising the switching frequency however, significantly increases the system switching losses which generally precludes operating at switching frequencies greater than 100 kHz.
A fast-response sliding-mode controller for quadratic buck converter

The switched-mode power supplies are widely used in very low voltage and high-power applications where large conversion ratios are required. In such cases, the quadratic buck converter is the suitable one compared to buck, cascaded buck and multi-phase choppers, because of their limitations in switching frequency and losses. This paper presents mathematical analysis, design and simulation of a quadratic buck converter using fixed frequency Pulse-Width Modulation (PWM)-based Sliding-Mode (SM) controller in order to obtain fast dynamic performance. The design aspects include choice of sliding surface, deriving existing and stability conditions, control parameter selection and their analysis. The performance of the proposed converter is compared with the conventional Average Current-Mode (ACM) controller. In average current mode, the tuning of the PI controller for the inner current loop and outer voltage loop is done using bode plots. The simulation results for the two types of controllers are represented for analysing dynamic performance, as well as line and load regulations.
Large-range piston error detection technology based on dispersed fringe sensor

Synthetic aperture is the mainstream structure of current astronomical telescopes. However, after the synthetic aperture telescope is deployed in orbit, there will remain tilt and piston error between adjacent segments, which will sharply deteriorate the imaging quality of the optical system. The traditional piston error detection method based on dispersed fringe sensor has the question that it is difficult to detect the piston error within one wavelength, and the detection accuracy is restricted by the detection range. The method in this paper constructs multiple monochromatic light channels by opening windows in different areas on the dispersed fringe pattern, calculating and obtaining the feature value in each window to form a feature vector. Then, the convolutional neural network is introduced to distinguish the feature vector to detect piston error. Among them, the training set construction method adopted in this paper only needs raw data in one wavelength to construct a training set covering the entire detection range. Through simulation, the method proposed in this paper achieves the detection range of [-208λ, 208λ] (λ=720nm), and regardless of the presence of noise, the root mean square value of the detection error does not exceed 17.7nm (0.027λmin, λmin=660nm).
Dynamics and 2D temperature distribution of plasma obtained by femtosecond laser-induced breakdown

Recently, plasma produced by focusing femtosecond laser in gases has been introduced as an etching tool in materials processing. Proper control of the plasma in this application necessitates the apt understanding of the different morphological features of the plasma. In this contribution we show that, the plasma produced in air goes through several stages of morphological development–from ellipsoidal to spherical to toroidal plasma, whereas in argon, axial compression of an ellipsoidal plasma is observed. To explain this dissimilarity, we have quantified the temperature by emission spectroscopy (Planck analysis with Wien’s approximation). The evolution of temperature shows a triple exponential dependence in time which can be correlated with different stages of morphological changes of the plasma. Open Source Field Operation and Manipulation simulations using experimentally determined temperature values show that—(i) the reverse pressure gradient propagates radially inwards and compresses the plasma in both air and argon and forms a localized high pressure zone at the center that generates a secondary pressure wave in air, but not in argon, and (ii) the baroclinic torque that is generated because of the Richtmyer–Meshkov instability, dominates the rate of vorticity in air, whereas effects of flow compressibility and velocity gradients dominate the vortices in argon. Knowledge of the initial state and the dynamics of the subsequent stages of the plasma formation can be utilized for control and optimization of laser-induced plasma applications.
