Abstract:

Hydraulic engines can be widely used in many fields, such as agricultural machinery, construction machinery, duty vehicle, and many other fixing or mobile devices. The development analysis and study on their structural principle, technical and operational characteristics will be undoubtedly very useful for putting forward new type hydraulic engines. The structural principle of Hydraulic Free Piston Engine, Hydraulic Confined Piston Engine was introduced. The structural principle of Half Crank Hydraulic Engine (HCHE), which inherits the merits of traditional engine, HFPE and HCPE, was put forwa

Abstract:

Life is evolutionarily the most complex of the emergent symmetry-breaking, macroscopically organized dynamic structures in the Universe. Members of this cascading series of disequilibria-converting systems, or engines in Cottrell's terminology, become ever more complicated—more chemical and less physical—as each engine extracts, exploits and generates ever lower grades of energy and resources in the service of entropy generation. Each one of these engines emerges spontaneously from order created by a particular mother engine or engines, as the disequilibrated potential daughter is driven beyon

Abstract:

The general principles of automatic control of aircraft engines and functionally related systems in the conditions of their stand tests are suggested. These principles are prospectively reduced to six sequentially implemented procedures or steps. In accordance with these principles, the control of aircraft engine parameters is carried out by a computer-aided test equipment (CTE) based on a computer complex that implements algorithms based on Boolean algebra and the algebra of events and states. These algorithms allow control procedures to be carried out in dynamic mode in accordance with the s

For a diesel engine, operating conditions have extreme importance in fault detection and diagnosis. Limited to various special circumstances, the multi-factor operating conditions of a diesel engine are difficult to measure, and the demand of automatic condition recognition based on vibration signals is urgent. In this paper, multi-factor operating condition recognition using a one-dimensional (1D) convolutional long short-term network (1D-CLSTM) is proposed. Firstly, a deep neural network framework is proposed based on a 1D convolutional neural network (CNN) and long short-Term network (LSTM)

Automated program repair is an emerging technology that seeks to automatically rectify program errors and vulnerabilities. Repair techniques are driven by a correctness criterion that is often in the form of a test suite. Such test-based repair may produce overfitting patches, where the patches produced fail on tests outside the test suite driving the repair. In this work, we present a repair method that fixes program vulnerabilities without the need for a voluminous test suite.

Abstract:

During the manufacture and overhaul of gas turbines, it is necessary to ensure that all blades in a stage are of an equal and known length to minimize the loss in performance that arises as a consequence of the clearance between rotor tip and engine casing. Modern compressor and turbine blades are generally loose fitting in their root fixings and only adopt their true working position when running. In this paper, a new technique for measuring the rotor radius over individual blades is described. The measurement technique utilizes a capacitance-based clearance measurement system, which enables

Abstract:

Understanding why individuals engage in sport corruption is an emerging topic of research. Micro-level accounts of corruption have generally used a single disciplinary approach toward understanding why actors commit corruption (e.g., doping and match-fixing) in specific sports. The purpose of this study was to first examine individual-level explanations of corruption in the context of intercollegiate athletics; and, second, to generate an interdisciplinary framework. A multi-case analysis was conducted of 20 National Collegiate Athletic Association (NCAA) major infractions (corruption) reports

Abstract:

Legume plants engage in intimate relationships with rhizobial bacteria to form nitrogen-fixing nodules, root-derived organs that accommodate the microsymbiont. Members of the Nuclear Factor Y (NF-Y) gene family, which have undergone significant expansion and functional diversification during plant evolution, are essential for this symbiotic liaison. Acting in a partially redundant manner, NF-Y proteins were shown, previously, to regulate bacterial infection, including selection of a superior rhizobial strain, and to mediate nodule structure formation. However, the exact mechanism by which thes

To succeed in such diverse environments, the bacteria must continually adjust gene expression. Transcriptional plasticity in eubacteria is often mediated by alternative sigma (σ) factors interacting with core RNA polymerase. TheS. melilotigenome encodes 14 of these alternative σ factors, including two putative RpoH (“heat shock”) σ factors. We used custom Affymetrix symbiosis chips to characterize the global transcriptional response ofS. melilotirpoH1,rpoH2, andrpoH1 rpoH

Abstract:

Public licenses have earned a strong position in both protection and transfer of Intellectual Property Rights. Public licenses are an essential part of activities of many companies, projects and even research grants and their use is increasing. This development means that IPRs and related products protected by public licenses engage in competition with products, protected by more traditional licensing schemes. Thus, even public licenses must be assessed through competition law scrutiny. Recent case law and scientific work clearly show that viewing public licenses through competition law perspe

Abstract To effectively manage the traffic flow in order to reduce traffic congestion, it is necessary to know the volumes and quantitative indicators of this flow. Various detection methods are known for detecting a vehicle in a lane, which, in turn, have their own advantages and disadvantages. To detect vehicles and analyse traffic intensity, the authors use a pulse coherent radar (PCR) sensor module. Testing of various modes of operation of the radar sensor was carried out to select the optimal mode for detecting vehicles. The paper describes a method for fixing vehicles of different sizes,

This article examines how older, Western residents make sense of racial and economic hierarchies in the context of relations with Balinese employees and a modern service infrastructure of cafes and restaurants in Ubud, Bali. I examine how these residents engage with contradictory moral regimes that reflect a desire to downplay white privilege, yet place the self at the forefront of narratives of life and lifestyle in Bali. The spatial management of such concerns, I argue, is complicated by a desire to impose fixity on socio-cultural process, in ways that bring symbolic pollution beliefs to the

Abstract:

Most legumes can engage in symbiosis with N-fixing bacteria called rhizobia. This symbiosis, called nodulation, evolved from the more widespread symbiosis that most land plants form with arbuscular mycorrhiza, which is reflected in a common requirement of certain genes for both these symbioses. One key nodulation gene, Nodule Inception (NIN), has been intensively studied. Mutants in NIN are unable to form nodules, which has made it difficult to identify downstream genes under the control of NIN. The analysis of data from our recent transcriptomics study revealed that some genes with an altered

Abstract:

Rhizobia are soil proteobacteria able to engage in a nitrogen-fixing symbiotic interaction with legumes that involves the rhizobial infection of roots and the bacterial invasion of new organs formed by the plant in response to the presence of appropriate bacterial partners. This interaction relies on a complex molecular dialogue between both symbionts. Bacterial N-acetyl-glucosamine oligomers called Nod factors are indispensable in most cases for early steps of the symbiotic interaction. In addition, different rhizobial surface polysaccharides, such as exopolysaccharides (EPS), may also be sym

The jurisprudence of the Supreme Court of India is generally celebrated in the academic literature for its creative use of constitutional interpretation to read in certain socioeconomic rights into the ‘right to life’ provision despite their textual absence from the Constitution. However, this line of case law made the obtainment of a judicial remedy highly conditional upon an extant scheme or law, was necessarily piecemeal, deferent to the executive, and incapable of fixing precise accountability upon a violation or addressing issues of systemic material insufficiency.
