HYDROLOGICAL UNDERSTANDING AND SOCIETAL ACTION 1

ABSTRACT: Hydrology is both an applied practical science and a pure geophysical science. The goal of hydrology, as a geophysical science, is to achieve theories capable of explaining with satisfactory accuracy the phenomena of interest. Through the rapidly accelerating power and versatility of digital computing technology, theory development and application are immensely facilitated via increasingly sophisticated predictive modeling schemes, which are now the principal operating tools both for applied management hydrology and for basic geophysical hydrology. While this approach treats phenomena as classes or generalizations, social and behavioral scientists have long argued that human beings base their actions on percepts, i.e., on the concrete specifics of their experience. Thus, the commonly held ideal of basing policy, decisions, and public actions on the best possible science encounters a conflict in belief systems. A possible resolution of this dilemma lies in the use of observational components, which in concept‐centered science serve as data to test or calibrate models. These components also serve as a great repository of natural experience that is closely attuned to the perceptual reality that propels societal action. Landscapes and sediments provide indices of real processes, whose occurrence can be expected by continuity to extend to present and future activity. More attention to research on such indices is warranted as a means of triggering perception‐based action by responsible decision‐makers. Grounded in reality, and tempered by their intrinsic fallibility, the scientifically powerful conceptual schemes (models) will then serve as guides to further action. The full societal benefit of hydrological science requires a balanced approach in which subdisciplines focused on environmental indices are afforded equal attention to those focused on conceptual idealization.
Testing and modelling a semi‐actively controlled steel frame structure equipped with MR dampers

In this paper, analysis of the shaking table tests performed on a four storey, large‐scale, steel mock‐up, equipped with a bracing system including magnetorheological (MR) dampers operating both in passive and semi‐active (SA) ON–OFF mode, is presented. The adopted SA control algorithm is derived from an ‘energy‐based’ instantaneous optimal control process.
Wideband bandpass filters using corrugated substrate integrated waveguide and periodic structures

Two wideband bandpass filters are designed and implemented by combining corrugated substrate integrated waveguides (CSIWs) and periodic structures, moreover, the novel CSIW is for the first time used for creating filtering devices. The CSIW performs similar to the traditional substrate integrated waveguide (SIW); however, it provides a completely floating conductor. As a result, active devices can easily be connected to the edge of the CSIW without using extra biasing chokes. With the help of the bandstop characteristics of periodic structures, such as defected ground structures (DGSs) and electromagnetic band gaps (EBGs), the proposed filters show wide passband, high frequency‐selectivity, and low insertion loss. The filters are fabricated and investigated, and the simulation results and experiment results are in good agreements. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2665–2668, 2015
Novel bandpass filter with size reduction and harmonic suppression

A novel microstrip bandpass filter with size reduction and harmonic suppression is proposed in this article. The filter is based on microstrip open loop resonators with coupled open stubs. By adding coupled open stubs to open loop resonator, extra controllable transmission zero can be obtained. The extra transmission zero can be tuned at the second harmonic frequency to suppress spurious response. When compared with the conventional microstrip open‐loop bandpass filter, this filter could achieve size reduction and spurious responses suppression simultaneously. A demonstration filter was designed, fabricated, and measured. Theoretical and experimental results are presented and show good agreement. © 2007 Wiley Periodicals, Inc.

Ultra wide band pass filters (UWBPF) based on complementary split rings resonators

In this work, a new strategy for the design of microstrip filters with ultra‐wide bandwidths is proposed. This is based on the combination of square‐shaped complementary split‐ring resonators (CSRRs) etched in the ground plane and grounded stubs. Coupling between adjacent resonators is achieved by means of λ/4 lines, acting as impedance inverters. To illustrate the potentiality of the approach, a prototype device with 90% fractional bandwidth has been designed for operation at C‐band. The measured fractional bandwidth (87%), in‐band losses (<1.3 dB), and out‐of‐band rejection (>30 dB), obtained on a device scaled down in frequency, point out the high performance achievable with this design methodology. Moreover, the first frequency parasitic (spurious) does not appear up to three times the central filter frequency. Due to the small dimensions, wide bandwidths, and compatibility with planar circuit technology, it is believed that the approach presented in this work can be of actual interest to the design of filters for ultra‐wideband applications. © 2005 Wiley Periodicals, Inc.

Tests and assessments of NDT methods for concrete bridges

A research project is described involving a comparison of different non-destructive test methods for concrete bridges. A cooperative test series was started with the aim to compare and evaluate the performance and benefits of the latest technical developments in this field. For this purpose test specimens with localized defects were produced. Different modifications of radar, ultrasonic-echo and impact-echo methods were investigated. Including two- and three- dimensional reconstruction models. The experiments were accompanied by numerical simulation of the propagation of sound waves and microwaves. The results showed that the radar and the ultrasonic methods were efficient tools to locate the tendon ducts accurately if the reinforcing bars were not to narrowly spaced. The ultrasonic imaging methods were capable of identifying injection and compaction faults in a blind test. The good performance of the impact-echo method with regard to locating tendon ducts which was claimed in several publications could not be validated in the present investigations. The simulation models provided valuable information on how to improve the experimental test program and its evaluation.
Biologically inspired climbing with a hexapedal robot

This paper presents an integrated, systems-level view of several novel design and control features associated with the biologically inspired, hexapedal, RiSE (Robots in Scansorial Environments) robot. RiSE is the first legged machine capable of locomotion on both the ground and a variety of vertical building surfaces including brick, stucco, and crushed stone at speeds up to 4 cm-s, quietly and without the use of suction, magnets, or adhesives. It achieves these capabilities through a combination of bioinspired and traditional design methods. This paper describes the design process and specifically addresses body morphology, hierarchical compliance in the legs and feet, and sensing and control systems that enable robust and reliable climbing on difficult surfaces. Experimental results illustrate the effects of various behaviors on climbing performance and demonstrate the robot's ability to climb reliably for long distances. © 2008 Wiley Periodicals, Inc.

Using a Public Education Campaign to Improve Driver Compliance with Streetcar Transit Lanes

On-street operation in mixed traffic is the least desirable right-of-way for light rail and tram systems. Melbourne, Victoria, Australia, operates one of the world's largest streetcar systems. Most of Melbourne's 195 km of streetcar tracks is protected by road rules that require traffic to avoid delays to trams. However, the rate of compliance with and the level of understanding of these rules are poor. This paper reviews the performance of a public education campaign, called Obey the Yellow, aimed at increasing the level of awareness of and the rate of compliance with road rules. It reports the results of community surveys and provides an analysis of the operational performance of the campaign. Community surveys established that the level of awareness of the road rules that apply to tram lanes has improved, with 28% of respondents saying that they changed their behavior after the campaign. Evidence about the tram system's operational performance suggests a small improvement, although this has not conclusively been linked directly to the campaign. Operations staff perceived improved driver compliance, but this impact is thought to have lasted less than 4 months after the campaign. There was no significant change in customer satisfaction with trams during the campaign. These results suggest that the campaign was successful in meeting its objectives of improved community awareness of road rules. However, any improvements with compliance have had only small, if any, impacts on reliability and travel time performance. The paper discusses the lessons learned from this experience and how they might be applied to improve streetcar performance in other contexts.
Factors related to pasung on people with mental illness

Physical restraint and confinement (pasung) by families of people with mental illness is known to occur in many parts of the world Pasung is a common human right violation on people with mental illness found on every country in the world especially in developing countries like Indonesia. In Indonesia the term pasung refers to the physical restraint or confinement of "criminals, crazy and dangerously aggressive people. Despite the classification as Human Right Violation, pasung is constantly performed in Indonesia. In 2018, around 18% people with mental ilness experienced pasung. This study aimed to identify factors related to pasung. The researcher conduct the literature review on the credible sources. Five databases were used including Science Direct, Proquest, Scopus, Ebsco, and Google Scholar. Study result identified that factors related to pasung come from person with mental illness, family and community. The pasung phenomena within the community on people with mental illness ironically have a limited sources of research especially the ethnographic study of the said phenomena. Ethnographic study on pasung is important to elucidate the social and cultural meanings of the practice in a variety of settings and cultures especially in Indonesia, which take an enourmous impact within the community including the practice of pasung on people with mental illness.

The advantages include their small size compared to multi-machine multi-inverter systems, lower weight, and overall cost. This article presents a consolidated study and comparison of vector control methods applied to multi-machine drives along with relevant simulation and experimental results. The mean control method and its modifications prove to be superior to the other control approaches.
Europol and EU Counterterrorism: International Security Actorness in the External Dimension

This article offers an analysis of Europol's security actorness in the external dimension of EU counterterrorism. While Europol has attracted some scholarly attention, not so much work has focused on the meaning of its international agreements in counterterrorism. This article aims to investigate the international actorness of Europol at the international level in relation to the fight against international terrorism. It offers original conceptual insights based on empirical case studies of international agreements: Europol agreements with U.S. law enforcement, as well as Europol agreements with countries in the European Neighbourhood policy.
Prediction of Crack Initiation of Rail Rolling Contact Fatigue

A plain-strain finite element (FE) model of the rail is developed by ABAQUS. The 1070 rail steel is considered in the model by Jiang and Sehitoglu's cyclic plastic constitutive equation. The wheel-rail rolling contact is represented by a moving load applied on the contact surface. Based on the FE results the initiation of rolling contact fatigue (RCF) crack is further evaluated by Jiang's fatigue model. Effects of the rail material inner defect and the friction coefficient are also investigated. The results show that the stress-strain state of the rail surface material becomes stable after about thirty passages. The maximum residual stress and strain are located in the subsurface. The life of a defected rail can be as low as 1/27~1/17 of a qualified rail, and the most probable location for crack initiation is highly dependent on the inner defect. The fatigue life is found to considerably decrease with the friction coefficient, while the location of crack initiation and its direction of propagation are less affected.
Is the Euphoria Surrounding Shariah-compliant Status Announcement long-lasting?- Event Study on Abnormal Returns of Incoming and Outgoing Firms in the Kuala Lumpur Shariah Index (KLSI) Listing

During the early years of Kuala Lumpur Islamic Index (KLSI), past literatures on the study of abnormal returns show investors’ euphoria surrounding the launching of the index and subsequent later studies, the sustainability of the abnormal returns in the long-run by comparing the performances of the KLSI against the conventional counterpart, Kuala Lumpur Composite Index (KLCI). Abnormal returns of KLSI were found to be significant in the short-run but unfortunately, absent in the long-run. With more extensive panel data (1999 – 2010), this study revisits the presence of the past euphoria by applying Buy-and-hold Abnormal Returns (BHAR) analysis. Unlike previous studies, this study assesses the short-run and long-run performances of the individual stocks rather than the index (KLSI) in order to remove the survivorship bias’ drawback of previous studies. In addition, to complement previous studies, analysis on the performance of stocks ‘expelled’ from KLSI (after losing shariah -compliant certification) also conducted. The study reveals the favourable short-run and long-run impact on firms attaining shariah-compliant status and the unfavorable impacts on firms losing shariah-compliant status, indicating that the investors are optimistic on the performance of firms attaining shariah-compliant status and pessimistic on firms losing shariah-compliant status. In essence, the findings indicate that shariah-compliant status provides information on past and present performance of the firms.
A Study on the Combined Effect of Obesity and Load Carriage on Plantar Pressure Patterns of Primary School Children

From childhood, children are required daily to carry a load (necessary to perform their regular school activities) that is often beyond the limits established for adult workers. While some critical issues related to possible negative consequences in terms of postural alterations and onset of musculoskeletal diseases are well known and investigated, little information is available for the population of overweight and obese children, which appears to increase year after year. As their bodies are physiologically subject to a certain degree of overload, the addition of a supplemental load may induce further stress, the effects of which should be carefully evaluated. This study focuses on the foot-ground relationship, with special attention on plantar pressure distribution. The primary goal is to assess whether or not backpack presence alters in different ways the physiological pressure patterns in obese subjects compared with normal ones. To this end, 45 obese and overweight children (6-10 years old) and an equal sample of non-obese schoolmates matched for gender, age and height, were tested with a pressure platform to acquire the plantar pressure distribution in absence and presence of a backpack. Results show that the carried load induces similar increases in both groups, even though a significant shift of the center of pressure in presence of a backpack was found for obese female subjects. The very high pressure peaks observed in the obese population suggest that further studies are required to evaluate specific issues of the musculoskeletal system related to the combination of load carriage and obesity.
PN Junction Defects Detection in Solar Cells Using Noise Diagnostics

PN junction is one of the most important parts of solar cells. Its quality affects lifetime and efficiency of solar cells. Local defects which appear in PN junctions during the manufacture process are very important from this point of view. These are caused by localized areas with high donor or acceptor doping agents, impurities, dislocations or other mechanisms which effect in lower breakdown voltage of PN junction in reverse bias. Several base methods can be used for solar cells nondestructive diagnostics. Measuring methods of low-band noise current effective value with reverse bias junction were used in this paper. This method allows detection of local defects and volume degradation in PN junctions of solar cells and it can be used for detection of microplasma noise. This noise is an impulse noise and it is caused by local avalanche breakdowns in small area of the junction. It can be recognized by two or more level random square current pulses with constant height, random appearance time and random pulse length. Information about these effects can be used in noise diagnostics of structural defects of PN junctions and then it can be used for quality and lifetime estimation of samples with these parameters.

WindFloat: A floating foundation for offshore wind turbines

This manuscript summarizes the feasibility study conducted for the WindFloat technology. The WindFloat is a three-legged floating foundation for multimegawatt offshore wind turbines. It is designed to accommodate a wind turbine, 5 MW or larger, on one of the columns of the hull with minimal modifications to the nacelle and rotor. Potential redesign of the tower and of the turbine control software can be expected. Technologies for floating foundations for offshore wind turbines are evolving. It is agreed by most experts that the offshore wind industry will see a significant increase in activity in the near future. Fixed offshore turbines are limited in water depth to ∼30–50 m. Market transition to deeper waters is inevitable, provided that suitable technologies can be developed. Despite the increase in complexity, a floating foundation offers the following distinct advantages: Flexibility in site location; access to superior wind resources further offshore; ability to locate in coastal regions with limited.
