Although research on various diamond polishing techniques has been carried for years, some issues still need to be examined in order to facilitate application on large areas in a cost-efficient manner. A compositive technique for machining efficiently thick diamond films prepared by DC plasma arc jet is reported in the present paper. A two-stage polishing was applied on thick polycrystalline diamond films, by employing first electro-discharge machining (EDM) for rough polishing and subsequently mechanical polishing for finishing operations. Experimental results obtained clearly indicate the applicability of the proposed two-stage technique for fabricating transparent diamond films that can be used for the production of X-ray windows. Appropriate etching with EDM is an effective pretreatment method for enhancing the efficiency of rough polishing process in mechanical polishing of thick diamond film. The machined surfaces of diamond films are studied by Scanning Electron Microscope (SEM) and Raman Scattering Spectroscopy (Raman).

In low oil price environments, conducting affordable enhanced oil recovery (EOR) projects can be very challenging. One item of interest for successful future EOR should be in how produced fluids are treated and how to achieve cost-efficiency. Nanoflooding, is an emerging EOR technique, which has attracted deployment in recent years. Meanwhile, Indonesia continues to progress towards the national oil and gas production target of one million barrels per day by 2030. This paper presents the observation of opportunities and challenges of using nanoflooding to enable oil and gas production in Indonesia to achieve its desired targets. The study began by mapping the pain points in major oilfields in Indonesia. We observed and discussed the advantage and limitation of traditional mature EOR techniques, status, and ongoing application of EOR in Indonesia. Then, we briefly explained the main reasons why nanoflooding can be considered for future implementation in accelerating oil production in Indonesia, including a discussion about a successful pilot test. As an emerging EOR technique, nanoflooding can be considered as a cost-efficient technique. Silica-based nanofluid can be accessed in a cost-efficient manner and can be executed from an implementation standpoint considering surface facilities. The mechanism that is introduced can help to displace incremental oil more effectively since it can go inside pore throats due to the nano-size. We observed several recognized benefits and challenges to deploy nanoflooding in Indonesia. Based on this study, nanoflooding is very attractive and has potential to be implemented.

This article examines various methods for involving children in family and child welfare proceedings, surveys varying approaches in different Canadian jurisdictions to the appointment of counsel for children in these cases, and explores the controversies about the role of counsel for children. While child representation is becoming common, in most provinces it is usually limited to welfare proceedings involving older children. All jurisdictions, however, have some provisions to allow for child participation in family relationship cases. Governments and law societies in Canada should develop more coherent and comprehensive programs and policies to ensure that the views of children are considered in the family justice process in a child-focused and cost-efficient manner. There needs to be more recognition of the role of lawyers in facilitating settlement. Appointment of counsel is, however, not always the best way to involve children ; if the child is willing to share views, in some cases this may be better done by a judicial interview, a Views of the Child Report or an assessment. There should be a presumption that counsel will be an instructional advocate, but if a child lacks the capacity or willingness to instruct counsel, counsel should be an advocate for the rights and interests of the child. Regardless of the role adopted, counsel for a child also has responsibility for introducing significant evidence not otherwise before the court.

AbstractThe inclusions of geosynthetic materials (fibers, geomembranes and geotextiles) is a new improvement technique that ensures uniformity in the soil during construction. The use of tension resisting discreet inclusions like polypropylene fibers has attracted a significant amount of attention these past years in the improvement of soil performance in a cost-efficient manner. A series of direct shear box tests were conducted on unreinforced and reinforced Chlef sand with different contents of fibers (0, 0.25, 0.5 and0.75%) in order to study the mechanical behavior of sand reinforced with polypropylene fibers. Samples were prepared at three different relative densities 30%, 50% and 80% representing loose, medium dense and dense states,respectively, and performed at normal stresses of 50, 100 and 200 kPa. The experimental results show that the mechanical characteristics are improved with the addition of polypropylene fibers. The inclusion of randomly distributed fibers has a significant effect on the shear strength and dilation of sandy soil. The increase in strength is a function of fiber content, where it has been shown that the mechanical characteristics improve with the increase in fiber content up to 0.75%, this improvement is more significant at a higher normal stress and relative density.

The triumphant Sandinista revolution inherited a health situation characterized by high mortality, low life expectancy, widespread malnutrition, and a medical system limited in scope. The extent of these problems can only be estimated as a result of the somocista government's failure to develop an accurate system of vital statistics. While there are many options available for rapidly decreasing the high levels of mortality and morbidity in Nicaragua, the revolutionary government has chosen a strategy which fuses public health and politics. A health network based on popular participation and control is being formed which should not only decrease the high rates of malnutrition and infectious diseases in a cost-efficient manner, but should increase the strength of the revolution as well.

Automated monitoring systems are now the standard on most large vessels; however, few are equipped with diagnostic systems. This paper presents new developments in the area of fault diagnosis based on intelligent software agents. The research objective was to design an agent capable of continuous real-time machine learning by using an artificial neural network known as the cerebellar model articulation controller (CMAC). An engine simulator that can model both normal and faulty engine operations was used to develop the learning system controller in a flexible and cost-efficient manner. This paper provides a description of the selected CMAC, a brief overview of the real-time engine simulator and its integration with the learning system as well as a few results.

Coverage Holes

Improving capacity and coverage is one of the main issues in next-generation wireless communication. Heterogeneous networks (HetNets), which is currently investigated in LTE-Advanced standard, is a promising solution to enhance capacity and eliminate coverage holes in a cost-efficient manner. A HetNet is composed of existing macrocells and various types of small cells. By deploying small cells into the existing network, operators enhance the users' quality of service which are suffering from severe signal degradation at cell edges or coverage holes. Nevertheless, there are numerous challenges in integrating small cells into the existing cellular network due to the characteristics: unplanned deployment, intercell interference, economic potential, etc. Recently, game theory has been shown to be a powerful tool for investigating the challenges in HetNets. Several game-theoretic approaches have been proposed to model the distributed deployment and self-organization feature of HetNets. In this chapter, the authors first give an overview of the challenges in HetNets. Subsequently, the authors illustrate how game theory can be applied to solve issues related to HetNets.

The Cost

In the 2000s, the idea of a so-called middle-segment arose in North-West Europe to address the criticism on intensive broiler production systems. Middle-segment systems being indoor housing of slower-growing broiler strains at a stocking density ≤38 kg/m2. Previous literature showed that Dutch middle-segment systems entail a relatively large gain in animal welfare at a relatively low increase in costs, i.e., have a high cost-efficiency. The question is to what extent these findings are applicable to other countries. Therefore, the aim of this study is to gain insight in the global prospects of middle-segment systems by exploring the cost-efficiency of these systems in other parts of the world. A set of representative countries, containing the Netherlands, United States and Brazil were selected. Cost-efficiency was defined as the ratio of the change in the level of animal welfare and the change in production costs. The level of animal welfare was measured by the Welfare Quality (WQ) index score. Data was collected from literature and consulting experts. Results show that in the Netherlands, United States and Brazil a change from conventional towards a middle-segment system improves animal welfare in a cost-efficient manner (the Netherlands 9.1, United States 24.2 and Brazil 12.1). Overall, it can be concluded that in general middle-segment production systems provide a considerable increase in animal welfare at a relatively small increase in production costs and therefore offer good prospects for a cost-efficient improvement of broiler welfare.

Marked changes in equine breeding technologies have occurred over the past 25 years. Although there have been numerous reviews on assisted reproduction techniques for horses, few publications include the acceptance and impact of these techniques on the horse industry. In this review, several techniques are discussed, with an emphasis on how they developed in the horse industry and altered equine reproductive medicine. Embryo transfer has become a widely used technology, allowing multiple foals to be produced per year. Embryos can be collected, cooled or frozen, and shipped to a distant facility for transfer into recipient mares. Failure to obtain embryos from some mares stimulated the development of oocyte collection and transfer. Oocyte technologies became more practical when intracytoplasmic sperm injection was developed in the early 2000s. There are now facilities across the world that routinely produce embryos invitro. Cryopreservation of oocytes has lagged because of limited success, but embryo cryopreservation is commonplace. Techniques such as sex-sorted semen, superovulation and genetic diagnosis of embryos are not widely used, and they will require more development before they are established in the horse industry in a cost-efficient manner.

ABSTRACT Efficient automated detection of flux-transient, re-occurring flux-variable, and moving objects is increasingly important for large-scale astronomical surveys. We present braai, a convolutional-neural-network, deep-learning real/bogus classifier designed to separate genuine astrophysical events and objects from false positive, or bogus, detections in the data of the Zwicky Transient Facility (ZTF), a new robotic time-domain survey currently in operation at the Palomar Observatory in California, USA. Braai demonstrates a state-of-the-art performance as quantified by its low false negative and false positive rates. We describe the open-source software tools used internally at Caltech to archive and access ZTF’s alerts and light curves (kowalski ), and to label the data (zwickyverse). We also report the initial results of the classifier deployment on the Edge Tensor Processing Units that show comparable performance in terms of accuracy, but in a much more (cost-) efficient manner, which has significant implications for current and future surveys.
