Prediction of Streamflow Recession Curves in Gauged and Ungauged Basins

Prediction of the time for perennial outflow from a natural basin to recede from the mean to some low flow value is an important practical and difficult problem in water resource management. This study aims to gain further understanding of this complex problem and to put forward new practical and accurate methods for predicting flow recessions between nominated limits in both gauged and ungauged basins. For a gauged basin, a three parameter recession model is employed to estimate the recession time, from day‐to‐day, as flow recedes from mean flow using previously measured site recession curves and a library of recession curve shapes generated by the RObust Parameter Estimation algorithm. The model is tested using data from 10 New Zealand basins which are diverse in low flow hydrological behavior and yields a Median Absolute Error (MAE) of 1 day. Another new model is also developed to predict recession time in an ungauged basin using catchment characteristics and information from master recession curves in a suite of 10 reference basins geologically and hydrologically similar to the ungauged basin, as assessed by a Random Forest model. Model performance is robust with a MAE of 1 day and the models advance the use of past flow records to enable more accurate predictions to be obtained. They can be applied elsewhere with confidence although further testing is desirable.
Time-Dependent Reliability of PSC Box-Girder Bridge Considering Creep, Shrinkage, and Corrosion

Bridge performance undergoes time-varying changes when exposed to aggressive environments. While much work has been done on bridge reliability under corrosion, little is known about the effects of creep and shrinkage on the reliability of concrete bridges. In this paper, the CEB-FIP model for creep and shrinkage is applied by using finite-element (FE) analysis in conjunction with probabilistic considerations. Verification is made by comparing the analytical findings with existing test data. More specifically, a time-dependent reliability assessment is made for a composite prestressed concrete (PSC) box-girder bridge exposed to a chloride environment. This realized via an advanced probabilistic FE method. The postcracking behavior of the thin-walled box girder is described using composite degenerated shell elements, and importance sampling is used to improve the efficiency of the reliability analyses. It is shown that concrete creep and shrinkage dominate during the early stages of bridge structure deterio.
Structural safety–issues and progress

A major aspect of ensuring safe structures is the management of uncertainty. The nature of safety, risk and uncertainty is discussed. Three types of uncertainty are considered: aleatoric, epistemic and ontological. The first is readily described in terms of probability distributions, so within this type of uncertainty, safety involves achieving less than a particular failure probability. The second cannot so easily be described by probability distributions, though the uncertainty can be estimated. The third type of uncertainty is essentially unknown. The different kinds of uncertainty call for different strategies. Probabilistic structural analysis deals with aleatoric uncertainty and to some extent epistemic uncertainty. Ontological uncertainty requires different strategies such as quality assurance or indicator methods. In addition, the traditional narrow focus on structural analysis is now broadening to include economic analysis and the social and environmental context of safety. This requires a different way of looking at safety. There is a shift from a narrow technical focus to the broader systemic viewpoint required for modern problems. The paper ends with a summary of problems needing to be addressed.
DGS resonator with two transmission zeros and its application to lowpass filter design

A novel defected ground structure (DGS) with two transmission zeros and a sharp cutoff frequency response is proposed. Both the two transmission zeros generated by the new DGS are lower than the one generated by a dumbbell-shaped DGS etched the same square area dimensions. On the basis of the proposed DGS, a lowpass filter has been designed, fabricated and measured. The filter with 3 dB cutoff frequency at 4 GHz exhibits a very sharp cutoff frequency response and an ultra wide stopband with rejection better than 25 dB from 4.2 to 23 GHz. Measured results show good agreement with simulated ones.
Optimum Reactive Control and Control by Latching of a Wave-Absorbing Semisubmerged Heaving Sphere

The theoretical potential for maximising energy output of wave-energy converters by means of optimum control is quantified for a heaving semi-submerged sphere on deep water. The heave amplitude is constrained to not exceed 0.6 units of the radius. Sinusoidal incident waves of amplitudes up to 3 m and period in the range of 6 s to 12 s are considered, when the sphere radius is 5 m. Optimum reactive control, contrary to sub-optimal latching phase control, requires ability for reversing the energy flow through the power take-off machinery. Computed results show that, for a typical wave of 0.5 m amplitude and 9 s period, the maximum absorbed power is 24, 137, and 172 kW for the cases of no phase control (passive system), sub-optimal latching control, and ideally optimal reactive control, respectively. The ratio between the maximum/minimum instantaneous power and the average absorbed power is 2/0, 4.1/0 and 11.0/-9.0, respectively, for the three different strategies.Copyright © 2002 by ASME
A simulation technique to compute phase noise induced from cyclostationary noise sources in RF oscillators

This paper describes a simulation method to compute oscillator phase noise which combines transient and periodic-transfer-function analyses, available in most of the commercial circuit simulators. The proposed calculation technique is simple to implement and provides the designer a deep insight into phase noise generation mechanisms for both stationary and cyclostationary sources, thus resulting a powerful tool to perform an optimum design in RF applications.
Relationship of rumination and self-compassion to posttraumatic stress symptoms among Veterans

ABSTRACT Past research demonstrates interrelationships amongst rumination, self-compassion, and posttraumatic stress disorder (PTSD) symptoms. However, little research has considered rumination and self-compassion together in relation to PTSD in clinical populations. In this cross-sectional study, we examined the unique effect of self-compassion on PTSD beyond the effect of rumination. Secondarily, we examined if rumination mediates the effect of self-compassion on PTSD. Participants included 52 US military Veterans (73.1% male) enrolled in a community support program for PTSD who completed self-report measures of study variables at one time point. Hierarchical regression results showed rumination was related to higher PTSD scores (f2 = .12; small ES) in step one, and the addition of self-compassion in step two was related to lower PTSD scores (f2 = .10; small ES) and explained a unique 9% of the variance. In contrast to previous research, results showed self-compassion mediated the relationship between rumination and PTSD, with a significant indirect effect (ab) of . 20 (95% confidence interval [CI] = .028 to .457). Findings suggest the explanatory value of self-compassion for PTSD after accounting for rumination and may also reflect a process where rumination about behaviors one regrets gives rise to uncompassionate responding, which then contributes to greater PTSD.
Stretchable copper interconnects with three-dimensional coiled structures

We propose a new scheme of stretchable metal interconnects utilizing the electroplated three-dimensional (3D) coil structure, as a strategy for improving the stretching performance of spring-like electrodes through the suppression of local stress concentration. In this process, the 3D copper coils are fabricated by a multi-step electroplating process, and embedded within an elastomeric substrate forming stretchable configuration. By comparing the stretching behavior of the two-dimensional and 3D coils under static or cyclic deformation, the beneficial effects of the 3D configuration have been demonstrated. The present technique can be regarded as an effective way to enhance the stability of interconnects under cyclic deformation significantly, while maintaining the high mechanical strength and electrical conductivity of electroplated electrodes.
L’endettement Est-Il Un Moyen D’ajustement Entre Les Besoins Et Les Ressources Ou Un Levier Créateur De Valeur?

Since the development of F. Modigliani and M. Miller's theorem (1958-1963), the financial literature has been abundant with works dealing with the impact of financing policy on value of the company. It is within this framework that the objective of this research falls, by posing the following problematic: Is debt a means of adjusting financial resources to the need for financing or on the contrary a source of creation valuable? Auteur correspondant à Mme ASSOUS Nassima,Email:assousnassima1@gmail.com Thus, our research aims to examine the impact of debt on value and empirically verify whether debt is a primary means for the business to be profitable. In order to respond to our research concern, we adopt a study based on the simple linear regression model and the "T.Student" significance test, applied to the cases of "N.C. A-Rouiba and Biopharm".
Riscos toxicológicos dos corantes de tatuagens: uma revisão narrativa

Objetivo: Abordar por meio de uma revisão narrativa, os potenciais riscos toxicológicos à saúde humana associados aos corantes para tatuagens. Revisão bibliográfica: As tintas de tatuagens são frequentemente uma combinação de água, compostos orgânicos e álcool isopropílico. Contudo, essa composição é bastante variável a depender do fabricante, sendo também encontrados pigmentos inorgânicos, pigmentos orgânicos e aditivos. Com a popularização das tatuagens nos últimos anos, o número de relatos envolvendo reações aos pigmentos tem aumentado. Foram encontradas na literatura, reações alérgicas e/ou de hipersensibilidade atrasada aos pigmentos, incluindo relatos de casos sobre uveíte pós tatuagem, assim como a identificação da presença de níquel e cromo na pele de indivíduos tatuados em decorrência do estresse mecânico das agulhas utilizadas na técnica. Verificou-se também que a quebra de partículas de pigmentos por fotodecomposição pode ocasionar aumento na toxicidade. Considerações finais: Evidencia-se a necessidade de maior rigor na regulamentação e fiscalização desses corantes, bem como a criação de normas padronizadas de controle de qualidade para os pigmentos, métodos de identificação e quantificação dos compostos utilizados.
Energy metabolism in high yielding cows

Whilst current rationing systems are used to calculate the metabolisable energy (ME) requirements of dairy cows producing more than 50kg milk/day, the extent to which the digestive efficiency of the cow may be compromised at high intake levels has not been established. Equally the effect of a sustained energy deficit on milk composition is not known whilst the extent of energy contribution from mobilised tissue has not been quantified. This study was designed to examine energy metabolism in high yielding cows offered ad libitum total mixed ration during early/mid lactation.
Visual Memory Scan Slopes: Their Changes over the First Two Seconds of Processing

Using the prime–probe comparison paradigm, Jacob, Breitmeyer, and Treviño (2013) demonstrated that information processing in visual short-term memory (VSTM) proceeds through three stages: sensory visible persistence (SVP), nonvisible informational persistence (NIP), and visual working memory (VWM). To investigate the effect of increasing the memory load on these stages by using 1, 3, and 5 display items, measures of VSTM performance, including storage, storage-slopes, and scan-slopes, were obtained. Results again revealed three stages of VSTM processing, but with the NIP stage increasing in duration as memory load increased, suggesting a need, during the NIP stage, for transfer and encoding delays of information into VWM. Consistent with this, VSTM scan-slopes, in ms/item, were lowest during the first NIP stage, highest during the second NIP stage, and intermediate during the third, non-sensory VWM stage. The results also demonstrated a color-superiority effect, as all VSTM scan-slopes for color were lower than those for shape and as all VSTM storages for color are greater than those for shape, and the existence of systematic pair-wise correlations between all three measures of VSTM performance. These findings and their implications are related to other paradigms and methods used to investigate post-stimulus processing in VSTM.
A Novel Corner Detection Based on Improved SUSAN Model

The paper proposes a novel corner detection algorithm based on classical Susan model. The improvement is given from two aspects. One is the choice of the self-adaptive threshold. The other is that we present a rotate coordinate system to find all possible corner points. Experiment result shows that the modified algorithm is robust and of high efficiency.
Burr Hole Surgery for Drainage of Chronic and Subacute Subdural Hematomas: Low Recurrence Rate in a Single Surgeon Cohort

Background: A complication after surgical intervention for chronic and subacute subdural hematoma drainage is the recurrence of hematoma, often requiring repeat surgical management. Recurrence rates varied widely across the published series, which may partially be due to different technical strategies used by the surgeons involved in the study. We decided to review our patients with chronic and subacute subdural hematomas that were surgically managed with a burr hole procedure by a single surgeon to compare recurrence rates with the evidence available. Methods: A retrospective review of the medical records was performed on the patients who underwent burr hole surgical intervention to drain a chronic or subacute subdural hematoma between April 1995 and March 2020. All patients were under the care of a single surgeon at an academic institution. Variables analyzed included age, sex, laterality of the hematoma, and recurrence. Results: During the selected timeframe, 610 cases were identified. There were 35 cases of recurrence of the hematoma. The recurrence rate after burr hole drainage was 5.73%. Conclusion: Surgical drainage of chronic and subacute subdural hematoma via burr hole using consistent stepwise management is associated with a relatively low recurrence rate in our single surgeon patient cohort.
Theory of eddy-current brakes with thick rotating disc

The braking forces acting on a thick conducting disc rotating in the field of rectangular electromagnets are examined. The analysis is based on the solution of quasi-one-dimensional vector potential in the plate and airgap regions of the device. Finite thickness of the plate is taken into account explicitly in deriving the general expression for the braking force. This expression is shown to reduce to the conventional induction motor characteristic in the thin plate limit and a simple original expression is presented for the calculation of braking forces in the skin-effect region.
Consumer Motivation by Using Unified Theory of Acceptance and Use of Technology towards Electric Vehicles

The transport sector is the leading source of growing greenhouse gas (GHG) emissions globally. To consider environmental degradation aspects due to transport, electric vehicles (EVs) have the prospect to lead road transport to electric mobility from conventional petroleum vehicles. Despite various eco-friendly benefits, the EV market penetration ratio is very low, especially in developing countries. The primary reason for low penetration is consumer limited motivation and knowledge about the EVs features. This paper uses a unified theory of acceptance and technology (UTAUT) model to assess consumer motivation and environmental knowledge towards EVs. This research used convenience random sampling to collect data and analyzed the results using the Partial Least Squares (PLS) method on the example of 199 respondents from Malaysia. The study results revealed that factors identified in the motivational context significantly influence consumer intentions to purchase EVs. Perceived environmental knowledge and technophilia have been included in UTAUT from a motivational perspective. Furthermore, a significant relationship between effort expectancy, social influence, technophilia, perceived environmental knowledge, and purchase intention towards electric vehicles has been observed, without performance expectancy. The study findings serve to inform policymakers and automakers to formulate effective marketing strategies to enhance consumer motivation, knowledge, and value creation for EVs in a sustainable era. Ultimately, the policies will help to encourage consumers to buy eco-friendly vehicles that will help reduce transport carbon emissions and attain sustainable development goals (SDGs).
Self-diplexing antenna using the square patch with a hole

The paper proposes a double-layered circularly polarised self-diplexing antenna (SDA) using a square patch with a shorted hole, which is a new type antenna with improved diplexing characteristics. The equivalent relative permittivity can be adjusted by changing the size of hole. The E-plane radiation energy at /spl plusmn/90/spl deg/ is largely reduced when the relative permittivity is unity. To utilise this characteristic, a double-layered SDA is proposed which consists of the lower layer of a square patch with a hole and the upper layer of a 0.5 /spl lambda//sub 0/ airgap square patch. Using this antenna, the isolation level was improved by a minimum of -54 dB.
Third‐order dual‐band filter with dual‐band admittance inverter

In this article, stepped impedance resonator with dual‐band admittance inverter is proposed to design the dual‐band microstrip filter to operate at (2.4, 5.2) GHz and at (0.9, 2.3) GHz, respectively. The proposed dual‐band microstrip filter consists of stepped‐impedance resonators (SIRs) in shunt cascaded by dual‐band inverter. The half‐wavelength SIR is constructed to simultaneously excite the dual resonances at those specified frequencies. The dual‐band admittance inverter used is composed of two open stubs and one transmission line to make the contribution of the performance of the J‐admittance. The transmission zeros of the admittance inverter can also enhance that of SIRs. The enhanced transmission zeros can be designed on the basis of the required J value and characteristic impedances of the inverter. The study has indicated that the proposed structure and method can achieve the design goals of dual‐band filter. Experimental filters are fabricated and measured to confirm the design. © 2010 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:140–143, 2011; View this article online at wileyonlinelibrary.com.

A newly revised edition of the popular 1994 book, this clear account of plants from which natural dyes can be obtained will be welcomed not only by all who work with fiber arts but also by botanists. The authors have selected 48 plants from different parts of the world and they describe each plant's structure and cultivation, the history of each as a dye source, and the best method for a plant's use based on their own experiments. Most well-known dye plants are discussed, and each plant is beautifully illustrated by Gretel Dalby-Quenet in a full-page painting that shows the colors the plant can yield.
Comparing electronic probes for volumetric water content of low-density feathermoss

Purpose – Feathermoss is ubiquitous in the boreal forest and across various land‐cover types of the arctic and subarctic. A variety of affordable commercial sensors for soil moisture content measurement have recently become available and are in use in such regions, often in conjunction with fire‐susceptibility or ecological studies. Few come supplied with calibrations suitable or suggested for soils high in organics. Aims to test seven of these sensors for use in feathermoss, seeking calibrations between sensor output and volumetric water content.Design/methodology/approach – Measurements from seven sensors installed in live, dead and burned feathermoss samples, drying in a controlled manner, were compared to moisture content measurements. Empirical calibrations of sensor output to water content were determined.Findings – Almost all of the sensors tested were suitable for measuring the moss sample water content, and a unique calibration for each sensor for this material is presented. Differences in sensor.

Estimating the Impacts and Uncertainty of Climate Change on a Municipal Water Supply System

The preponderance of evidence in the scientific community supports the premise that global climate is changing. The precise impacts of climate change on natural and man-made systems remain less certain. Municipal water supplies, particularly those that rely on summer snowmelt to augment storage capacity, may experience significant changes in their flow regimes in the future. This paper presents an evaluation of climate change impacts on a water resource system using a three-stage modeling approach: General circulation models (GCMs) to simulate global climate, basin scale hydrology models, and water resource system simulation models. This approach is applied to two river basins in the Puget Sound Region of the Pacific Northwest: The Cedar and South Fork Tolt Rivers, which are the principal sources of water for the Seattle metropolitan region. The greatest source of uncertainty associated with climate change impacts arises from the range of future scenarios produced by GCMs. This uncertainty is addressed by.
PROCESS MODELLING FROM REFLECTIVE PRACTICE FOR ENGINEERING QUALITY

Abstract Reflective practice, as previously introduced (Schon, 1983; Dias, Blockley, 1995), is used to begin the development of a language for the modelling of processes be they physical, human or organisational. The aim is to improve the quality of both products and processes in the short term for immediate application with ‘passive’ data and in the longer term for process enactment in inter/intranet systems with ‘active’ data. One simple advantage will be improved handling of problems with often occur at the interface between difficult technical problems and human and organisational issues. The hypothesis presented is that everything is an holistic process. The theory is based on the reflective practice loop. Attributes of process models are presented and an algorithm is given for determining them. Some suggestions for generic organisational processes are presented. The models can be used with standard project management tools if deemed necessary. The potential benefits from adopting these ideas are imp.
Treachery and Deceit: Parallels in Tribal and Terrorist Warfare?

The use of treachery (a deliberate betrayal of trust) and deceit (the ensnaring by guile) are generally overlooked aspects of warfare, whether in tribal or state societies. What distinguishes treacherous attacks from other forms of ambush is the necessity of peaceful social interaction between attacker and victim immediately prior to the assault. This article examines the cross-cultural evidence for its use in tribal societies, and relates the implications of these findings to the apparent use of treachery and deceit in a number of guerrilla/terrorist conflicts, including the Al Qaeda attacks of 11 September 2001.
