Rethinking Suicide

This book presents a critical evaluation of conventional wisdom and traditional assumptions about suicide, with particular attention focused on the assumed centrality of mental illness. It argues that suicide prevention efforts have disproportionately emphasized mental health-focused solutions, notably access to treatment and crisis services, based on research studies that are susceptible to bias and faulty interpretations of research findings. Instead of viewing suicide as a mental health issue, suicide should instead be seen as a “wicked problem” that defies ordinary solutions. Wicked problems cannot be definitively solved or eliminated by conventional solution-oriented thinking, and require process-based thinking that may, in some cases, defy or contradict many of our long-held assumptions about suicide. To flesh out this alternative approach to suicide prevention, the book interweaves historical accounts and personal stories with explanations of scientific findings to illustrate the limitations of widely-used practices and introduce alternative perspectives that could catalyze a paradigm shift in how we think about and prevent suicide.
Optimization of Farm-to-Market Road Investment and Maintenance Activities in Selected Developing Countries

The objective of the administration of farm-to-market roads in countries such as the Central African Republic, Liberia, and South Sudan is to optimize maintenance activities in relation to improving road safety and minimizing life-cycle costs, including road investment, maintenance, and road user costs. The decision on the selection of the most feasible and affordable road dimensions and characteristics, such as all-weather or weather-dependent accessibility, is based on engineering and economic analysis of costs and benefits related to the level of accessibility and the economic life expectancy of the road network. In selected rural areas of African countries such as the Central African Republic, Liberia, and South Sudan, road improvement is a component of an area development program. Traffic volumes are less than 50 vehicles per day (vpd) on these roads, and the development program includes both (a) an engineering and socioeconomic methodology that examines the relationship between road accessibility and agricultural production and (b) social services to evaluate the costs and benefits of the investments of the whole program. Rural investment is most efficient when the most economic type of roadway and the complementary agricultural investments are jointly optimized. The principal benefits achieved are reduced road user costs and reduction of agricultural spoilage. The paper concludes that, when the annual average daily traffic (AADT) is less than 50 vpd, the engineering-improved road surface is the most feasible solution. When the AADT is more than 50 and less than 300 vpd, the most feasible road surface is gravel, and when the AADT is more than 300, blacktop resurfacing is justified.
Simulation framework for electromagnetic effects in plasmonics, filter apertures, wafer scattering, grating mirrors, and nano-crystals

Simulation Framework for Electromagnetic Effects in Plasmonics, Filter Apertures, Wafer Scattering, Grating Mirrors, and Nano-Crystals by Daniel Peter Ceperley Doctor of Philosophy in Engineering Electrical Engineering and Computer Sciences and the Designated Emphasis in Nanoscale Science and Engineering University of California, Berkeley Professor Andrew R. Neureuther, Chair This thesis presents a Finite-Difference Time-Domain simulation framework as well as both scientific observations and quantitative design data for emerging optical devices. These emerging applications required the development of simulation capabilities to carefully control numerical experimental conditions, isolate and quantifying specific scattering processes, and overcome memory and run-time limitations on large device structures. The framework consists of a new version 7 of TEMPEST and auxiliary tools implemented as Matlab scripts. In improving the geometry representation and absorbing boundary conditions in TEMPEST from v6 the accuracy
Characterization of Nominally Singlemode Fiber Systems Used in a Weakly Multimode Regime

The development of cheap laser diodes for large public applications such as compactdisc player has stimulated great interest in the use of nominally single-mode fibers at the wavelength of 1300 nm around 780 nm [3]. The last wavelength can be dedicated to the management of optical fiber networks. For this unusual usage, few studies on the performances of such weakly multimode systems are available. It is difficult to predict precisely the global performances (attenuation, bandwidth) because the systems in a weakly multimode regime are very sensitive to modal effects. The mode transition matrix technique developed by several authors is a powerful tool for characterizing the loss behaviour of a multimode fiber network [4, 5]. To evaluate the bandwidth of a multimode system, G. Evers has improved this technique by introducing the pulse delay and pulse broadening matrices [6, 7], but his approach is inconvenient to the weakly multimode systems. The method presented, also based on the Mode Transition Matrices (MTM), permits one both to take the mode coupling, the modal dispersions as well as the chromatic dispersion into account, and to follow the modal distribution along an optical fiber link. This method makes it possible to predict accurately not only the total loss but also the bandwidth of a multimode fiber network.
Tutorial:implementation of a pedestrian tracker using foot-mounted inertial sensors

Wearable inertial sensors are a convenient way to track pedestrians in situations where other localisation systems fail. More and more researchers are using inertial pedestrian tracking as a component in more complex applications. But despite the many publications on the topic, and the increasing availability of inertial sensors, implementing a reasonably accurate tracker can be challenging for researchers without a background in inertial navigation and Kalman filtering. With this article, we aim to provide fellow researchers with a simple yet effective implementation which works out of the box, but with enough clear explanations and references to allow for further investigation if required. We discuss common mistakes and practical aspects, such as parameter tuning and choice of sensors, which we found to be lacking in other work. The Matlab implementation and a few sample recordings are available online at http://eis.comp.lancs.ac. uk/pdr/.
Application of Over-Current Relay in Offshore Wind Power Plant with VSC-HVDC Connection

This paper presents the setting and coordination of over-current relays in an offshore wind power plant (WPP) grid connected only to the power electronic converters with limited fault current capability. The limited fault current injection capability of the converters has been considered as a hindrance for the relay setting. This characteristic can be utilized to develop a deterministic picture of the radial grid network and then the relays settings could be applied. The relay coordination has been demonstrated through an implementation in the Real Time Digital Simulator (RTDS) platform. The setting of relay parameters based upon maximum nominal currents is explained and the consequences are investigated.
Explicit approximations for the static capacitance of a microstrip patch of arbitrary shape

Closed-form expressions for the static capacitance of a microstrip patch of arbitrary shape are derived for both large and small patch size relative to the substrate thickness. For these formulas, only the capacitance of the isolated patch in free space, or the area, perimeter, and Neumann self-inductance of the perimeter are required. Comparison with existing data obtained by rather extensive numerical computation shows good agreement in the appropriate ranges of validity. The results of this paper have direct application to microstrip lumped circuit elements and to the evaluation of the quasistatic portion of the input impedance of a microstrip patch antenna.
Daily rainfall interpolation models obtained by means of genetic programming

The evolutionary computing algorithm of genetic programming (GP) was applied to obtain mathematical daily rainfall interpolation models in one climatologic station, using the measured data in nearby stations in Cutzamala River basin in Mexico. The obtained models take into account both the geographical coordinates of the climatologic station and also the elevation; the answer of these models was compared against those obtained by means of multiple linear regression, giving genetic programming models a better performance with respect to the multiple linear regression. Isohyets maps were then obtained to compare the spatial shapes between measured and calculated rainfall data in Cutzamala River Basin for a maximum historic storm recorded in year 2006, showing an adequate agreement of the results in case of rainfalls greater than 23 mm. Genetic programming represents a useful practical tool for approaching mathematical models of variables applied in engineering problems and new models could be obtained in several basins by applying these algorithms.
Predicting Neovascular Glaucoma risk in a Chinese Proliferative Diabetic Retinopathy population: development and assessment of a new predictive nomogram

Background: The aim of this study was to develop and evaluate a postoperative NVG risk nomogram based on the clinical data of a Chinese population of patients with PDR.Methods: A prediction model has been established based on the clinical data of 107 PDR patients who underwent vitrectomy from March,2017 to March,2018 in Shenyang Fourth People’s Hospital, and they were followed up for at least 12 months.The presence or absence of NVG were observed.The least absolute shrinkage and selection operator regression model was used to optimize feature selection for the postoperative NVG risk model. Multivariable logistic regression analysis was applied to build a predicting model incorporating the feature selected in the least absolute shrinkage and selection operator regression model. C-index, calibration plot, and decision curve analysis were also introduced to evaluate the model. The bootstrapping validation was also utilized to accomplish internal validation.Results: Risk factors screened out by the model included HbAlc level, presence of diabetic nephropathy and anti-VEGF therapy. The model was testified with a satisfying C-index of 0.852 (95% CI: 0.740–0.964). Decision curve analysis showed that the NVG nomogram was clinically useful when intervention was adopted with the NVG possibility threshold of 2%. Conclusion: This novel nomogram revealed that a good control of HbAlc level, absence of diabetic nephropathy and anti-VEGF therapy are prophylactic factors of postoperative NVG in PDR patients.
The heart of a new machine

Powerformer (an amalgam of power generator and transformer) is a radically new generator design that could herald a new era in high-voltage generation. The new machine from ABB is a 100 RPM, 11 MVA, 45 kV machine, installed as unit 9 (U9) of the Porjus Hydropower Centre, on the Lule river in northern Sweden. The Powerformer uses a cable-wound stator using XLPE insulated cable. The cable's circular cross section solves the two basic problems arising from the use of conventional, rectangular stator windings. First, within the stator slots, the uniform field in the insulator maximises insulation performance, and hence the voltage rating of the cable. Secondly, bending a cable of circular cross section does not result in the kinks and sharp edges that arise with a rectangular cable. Thus, even in the end regions, where the cable is bent to make the transition from one slot to the next, the electric field within the insulator remains free of singularities. In the end regions of the Powerformer the electric field remains confined within the cable, and the need to control an external electrical field as in a conventional machine, is eliminated.
Toward a new flickermeter based on voltage spectral analysis

The paper discusses how flicker prediction can be directly achieved by means of a spectral analysis of voltage. Weighing the spectral components in inverse proportion to the flicker perceptibility threshold is the main concept, proposed in a previous paper by the same authors. That approach is here improved and subjected to the IEC flickermeter calibration tests. The results of comparative applications of this approach and of the IEC flickermeter to numerical and experimental data are discussed and analyzed.
Fake News Detection with Machine Learning

This news can become a major issue to the public and government bodies (especially politically) if its fake hence authentication is necessary. It is essential to flag the fake news before it goes viral and misleads the society. In this paper, various Natural Language Processing techniques along with the number of classifiers are used to identify news content for its credibility.Further this technique can be used for various applications like plagiarismcheck , checking for criminal records.
Implementation of naturally sampled space vector modulation eliminating microprocessors

In this paper, an implementation method of the SVPWM (space vector PWM) excluding a microprocessor is presented. It is analyzed that the SVPWM is equivalent to the conventional naturally sampled SPWM (sinusoidal PWM) with a special type of the zero sequence component. The zero sequence component is generated from the three reference voltage waveforms using a three-phase diode bridge and an inverting adder. Experimental results are provided to demonstrate the validity of the proposed method.
Designing and configuring the value creation network for servitization: a product-service provider's perspective

Despite the numerous benefits that the implementation of a servitization strategy can bring to manufacturing companies, several challenges have to be faced. Among others, changes in competences, resources, organisational structure and value network relationships are required in order to create, capture and deliver new value. In such a context, this thesis investigates how the servitization level of a PS offering impacts on a PS provider as well as on its value-creation network. A theoretical conceptual model, derived from literature, is developed and then expanded into an explanatory conceptual framework through a case-based methodology. Evidence from the empirical investigation are then discussed and summarised into twelve propositions. Finally, contribution to both theory and practice, as well as some directions for future research, are pointed out.
Phase extraction based on sinusoidal extreme strip phase shifting method

Multiple synthetic aperture imaging can enlarge pupil diameter of optical systems, and increase system resolution. Multiple synthetic aperture imaging is a cutting-edge topic and research focus in recent years, which is prospectively widely applied in fields like astronomical observations and aerospace remote sensing. In order to achieve good imaging quality, synthetic aperture imaging system requires phase extraction of each sub-aperture and co-phasing of whole aperture. In the project, an in-depth study about basic principles and methods of segments phase extraction was done. The study includes: application of sinusoidal extreme strip light irradiation phase shift method to extract the central dividing line to get segment phase extraction information, and the use of interference measurement to get the aperture phase extraction calibration coefficients of spherical surface. Study about influence of sinusoidal extreme strip phase shift on phase extraction, and based on sinusoidal stripe phase shift from multiple linear light sources of the illumination reflected image, to carry out the phase shift error for inhibiting the effect in the phase extracted frame.
Minimising native non-target uptake of 1080 fox baits

Red foxes (Vulpes vulpes) are a significant pest species threatening the survival of endangered and vulnerable native Australian fauna. Lethal baiting with the toxin 1080 is currently the most widely implemented form of control. However, non-target uptake is a problem, even in Western Australia where most native species have a high 1080 tolerance. It reduces the number of baits available to foxes and therefore the efficiency and cost-effectiveness of 1080 fox baiting operations. To investigate bait presentation and the use of aversive tastant agents as potential techniques to reduce non-target uptake of 1080 baits, two separate studies were conducted. Study 1 examined different non-toxic meat bait presentations to find the presentation that had the lowest non-target uptake. Baits were laid on the surface, suspended, buried or wrapped in kangaroo hide. Study 2 investigated the effectiveness of potential deterrents in causing aversion both immediately and accumulatively over time. Nine different deterrents (washing-up liquid, citric acid, wasabi, baking powder, bicarbonate soda, salt, sodium saccharin, Bitrex and chilli) were tested for immediate aversion and chilli and Bitrex were tested for accumulative aversion. A cafeteria-style presentation was used, with deterrents applied to apple baits of control, low and high concentrations. For Study 1 and 2 animal activity and bait take were monitored on remote-sensing Reconyx cameras for later photo analysis. The results of Study 1 suggested no significant effect of bait presentation. However, as hypothesised the longevity and non-target uptake was lowest for buried baits. Study 2 suggested that salt, wasabi and chilli created immediate aversion in the most abundant non-target species, quokkas. However, aversion was only carried-over onto untreated apple baits in wasabi and chilli. These findings suggest that bait presentation and the use of aversive tastant agents may have potential to decrease non-target uptake and be employed in future baiting 1080 fox baiting operations.
EQUIVALENT MATERIAL PROPERTIES OF PERFORATED PLATE WITH TRIANGULAR OR SQUARE PENETRATION PATTERN FOR DYNAMIC ANALYSIS

For a perforated plate, it is challenging to develop a finite element model due to the necessity of the fine meshing of the plate, especially if it is submerged in fluid. This necessitates the use of a solid plate with equivalent material properties. Unfortunately, the effective elastic constants suggested by the ASME code are deemed not valid for a modal analysis. Therefore, in this study the equivalent material properties of a perforated plate are suggested by performing several finite element analyses with respect to the ligament efficiencies.
PERANCANGAN MESIN REMAS (SQUEEZE MACHINE) UNTUK TERAPI AUTISME

The last two decades, in the world of autism increased dramatically. In 1990 obtained 4 from 10000 births (1: 2500). In 2000 to 2008 be 1: 88, increased nearly 30 fold. Deep pressure therapy is a method of providing the pressure and the amount of time on the outside of the body most deeply and evenly. Deep pressure generated by stress relieving device, such as squeeze machine. Squeeze machine can give the effect of calmness to the people hypersensitive to sensory stimulation, such as autism. In Indonesia, squeeze machine is still rare because the price is quite expensive. As needed, it should be designed at an affordable price without compromising quality. Phase of the design process, namely: (1) project definition, project planning, and preparation of technical specifications of the product, (2) the design concept of the product, (3) designing embodiment product, and (4) preparation of documents for the manufacture of products. Squeeze machine model design concept originated from the use of the prone position, deep pressure of a V shaped wall. Squeeze machine design usage position supine position, deep pressure of the three arms, namely: (1) hand and body, (2) the hip and thigh, and (3) the lower leg. For ages under 8 - 9 years, deep pressure 30 - 40 psi within 15 - 45 minutes. At the end of the design process gained some documents as the basis for the manufacture of prototypes, namely: (1) layout drawing, (2) arrangement drawing (assembly), (3) detail element drawing, and (4) the bill of materials.
A frequency approach for current loop modeling with a PWM converter

A new method based on a frequency approach is used to obtain a transfer function model of a DC permanent magnet actuator driven by a pulse width modulated (PWM) amplifier for robot applications. The paper investigates two carrier waves used in industrial applications with analog or digital control. The accurate model presented takes into account supply amplifier-motor dynamics and includes the input control voltage sampling effect. Advantages and limitations of both carriers and control waves are discussed. As a result, information about harmonics angle, magnitude and distortion are provided. The PWM model is tested through simulations and experiments with initially an open loop system then with a closed loop system, which introduces ripple current effect in the feedback control path.
Crash Prediction Method for Freeway Facilities with High Occupancy Vehicle (HOV) and High Occupancy Toll (HOT) Lanes

This study developed methods for estimating the expected crash frequency of urban freeway segments with High Occupancy Vehicle (HOV) or High Occupancy Toll (HOT) lanes. The safety impacts of the type of separation between the managed lanes and general purpose lanes were examined. Separate models were estimated for fatal and injury (FI) crashes and all crashes. The models for facilities with HOV lanes were estimated using five years’ of data from California, Washington, and Florida. All these facilities have one HOV in each direction (included in the count of total number of lanes). The effect of separation type on crash rates is found to be statistically significant only in the models for ten-lane facilities. The models for freeways with HOT lanes were estimated using four years’ of data from 27 miles (48 segments) of freeways from the states of California, Texas, and Florida. All these facilities have two HOT lanes in each direction. Facilities with a 1-foot separation are estimated to have more crashes than those that have a 3-foot separation which in turn have more crashes than facilities with a 20-foot separation. All the estimated models have been implemented in a spreadsheet program which will enable analysts to apply these equations for crash prediction. Overall, this study provides procedures that will help Florida Department of Transportation (FDOT) consider safety in decisions about planning and designing freeways with HOV or HOT lanes.
