TVs, laptops, head-mounted displays, heads-up displays and augmented reality headsets, broadcast reference boards, medical monitors, cell phones, smart gadgets are familiar with the present world. Significant advances in display technology are steadily developing visual environments from CRTs to New Quantum Dots Technology as per improvement in the modern age. The visual environment starts with the small LED (Light Emitting Diode) display that displays numerical contain, then after jumbo CRT (cathode ray tubes) The evolution continued from a lighter and simpler to bring LCD (Liquid Crystal Display), but the key issue with LCD is that it does not see consistent images from various angles. The ground-breaking discovery of OLED overcame this challenge (Organic Light Emitting Diode). The inhabitants of the Planet are faced with a severe lack of energy supplies due to the increased population and consumption of more energy. The main concern of researchers and producers is thus directly related to the use of energy. A lot of research has been done in recent years to attain efficient and low-energy sources of light. The ability to produce versatile, transparent and very thin displays through Quantum dots Organic light emitting diode (QD-OLED) is important adaptive evolutionary advances in show (QD-OLED). With better power, QD-OLED has the ability to equal OLED's infinite contrast ratio.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82215094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A probabilistic thematic model was built to make it possible to cluster the publications of scholars in scientific areas, taking into account the citation network, which was an important step for solving the problem of identifying scientific subject spaces. As a result of constructing the model, the problem of increasing instability of clustering the citation graph in connection with a decrease in the number of clusters was solved. This problem would arise when combining clusters built on the basis of citation graph clustering, taking into account the similarity of abstracts of scientific publications. In the article, the presentation of text documents is described based on a probabilistic thematic model using n-grams. A probabilistic thematic model was built for the task of determining the completeness of covering the materials of an author’s dissertation research in scientific publications. The approximate values of the threshold coefficients were calculated to evaluate whether the articles of an author included the research provisions that were reflected in the text of the author’s abstract of the dissertation. The probabilistic thematic model for an author’s publications was practised on the basis of the BigARTM tool. Using the constructed model and with the help of a special regularizer, a matrix was found to evaluate the relevance of topics specified by the segments of an author’s dissertation abstracts to documents that are produced by the author’s publications. Important aspects of the possibilities of using latent semantic analysis were studied to identify tasks of scientific subject spaces and to reveal the completeness of covering the results of dissertation research science degree seekers.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"2012 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88152447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various routing protocols are designed basically to establish correct and efficient paths between source and destination. In the recent years, several routing protocols have been proposed in literature and many of them studied through extensive simulation at different network characteristics. In this paper, we compare the performance of three most common routing protocols of wireless sensor networks i.e. AODV, DSDV and ZRP. These protocols have been simulated using NS2 Package. This study investigates the routing protocols corresponding to packet delivery ratio, packet loss ratio, average throughput, dropped packets and end-to-end delay. Hence, evaluation and comparison between routing protocols is required because performance of any routing protocol can be changed with various parameters such as speed of nodes, pause times and number of nodes.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80401726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Taxonomy of Training Data: Disentangling the Mismatched Rights, Remedies, and Rationales for Restricting Machine Learning","authors":"Benjamin Sobel","doi":"10.2139/ssrn.3677548","DOIUrl":"https://doi.org/10.2139/ssrn.3677548","url":null,"abstract":"This chapter addresses a crucial problem in artificial intelligence: many applications of machine learning depend on unauthorized uses of copyrighted data. Scholars and lawmakers often articulate this problem as a deficiency in copyright’s exceptions and limitations, reasoning that legal uncertainties surrounding today’s AI stem from the lack of a clear exception or limitation, and that such an exception or limitation could resolve the current predicament. In fact, the current predicament is a product of two systemic features of the copyright regime — the absence of formalities and the low threshold of copyright-able originality — combined with a technological environment that turns routine activities into acts of authorship. Equilibrating the economy for human expression in the AI age requires a solution that focuses not only on exceptions to existing copyrights, but also on the aforementioned doctrinal features that determine the ownership and scope of copyright entitlements at their inception. \u0000 \u0000The chapter taxonomizes different applications of machine learning according to the qualities of their training data. Four categories emerge: (1) public-domain training data, (2) licensed training data, (3) market-encroaching uses of copyrighted training data, and (4) non-market-encroaching uses of copyrighted training data. Copyright can only regulate market-encroaching uses of data, but these uses represent a narrow subset of AI applications and exclude many of the most socially harmful uses of copyrighted materials. Moreover, paradoxically, copyright’s property-style remedies are ill-suited to addressing market-encroaching uses, and are in fact much more appropriate remedies for the categories of worrisome AI that fall outside copyright’s normative mandate. \u0000 \u0000Finally, this chapter discusses a variety of remedies to the “AI problems” it identifies, with an emphasis on facilitating market-encroaching uses while affording human creators due compensation. It concludes that the exception for Text and Data Mining in the European Union’s Directive on Copyright in the Digital Single Market represents a positive development precisely because the exception addresses some structural causes of the training data problem that this chapter identifies. The TDM provision styles itself as an exception, but it may in fact be better understood as a formality: it requires rights holders to take positive action to exercise a right to exclude their materials from training datasets. Thus, the TDM exception addresses a root cause of the AI dilemma rather than trying to patch up the copyright regime post hoc. The chapter concludes that the next step for an equitable AI framework will be to transition towards rules that not only clarify that non-market-encroaching uses do not infringe copyright, but also facilitate remunerated uses of copyrighted works for market-encroaching purposes.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80950208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use LSTM networks to predict the direction of stock movement and a numerical measure of the strength of the stock trend prediction, and use these in stock selection and within the Markowitz mean-variance portfolio optimization framework. Four types of LSTM models are constructed using the Indian SENSEX stock data - individual and ensemble models, each trained using both batch and incremental learning methods. We utilize the accuracy of classification of stock movement direction in shortlisting stocks for the portfolio optimization stage. Diversified and short-selling enabled Markowitz formulations in addition to the standard Markowitz formulation are constructed in the portfolio optimization stage. We also explore the use of a function of the LSTM classification accuracies as a risk measure both in lieu of and in addition to the covariance matrix within the Markowitz framework. Results from each of the above combinations of LSTM construction and portfolio optimization formulation type are benchmarked against the SENSEX and the standard optimal Markowitz portfolios without stock selection. We also analytically derive the conditions under which Markowitz formulations with stock price predictors more accurate than the mean stock price outperform the standard Markowitz formulations. Our work presents a framework that investment analysts can use to incorporate stock trend prediction outputs generated by machine learning techniques in informing their stock selection and optimal portfolio allocation decisions.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79275643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Transistor, an Emerging Invention: Bell Labs as a Systems Integrator Rather Than a ‘House of Magic’","authors":"Florian Metzler","doi":"10.2139/ssrn.3678081","DOIUrl":"https://doi.org/10.2139/ssrn.3678081","url":null,"abstract":"The transistor is one of the most consequential human inventions with dissemination of the eventual MOS-FET design estimated to exceed one quintillion devices. However, the transistor’s genesis remains poorly understood. Many received accounts associate transistor invention closely with a small group of Bell Labs scientists during the 1947-1948 period. This paper argues that such a view is too narrow. Rather, the transistor – as a solid-state amplifier – emerged over a period of several decades starting with early observations of anomalous amplification in semiconductor crystals and early device designs during the 1910s and 1920s. Other types of relevant knowledge evolved in the form of advances in solid-state physics and materials processing techniques during the 1930s and early 1940s. Bell Labs identified, absorbed, evaluated, and integrated such diverse but interrelated knowledge streams – making Bell Labs appear much more like a systems integrator than the prototypical closed innovation organization it is often portrayed as. The Bell Labs transistor effort was both mission- and device-oriented with the specific goal of turning existing but imperfect solid-state amplifier designs into reliable substitutes for vacuum tubes – as such the research program is better described as applied industrial research rather than basic research. Through its systems integration activities, Bell Labs catalyzed a qualitative shift in the hitherto fragmented semiconductor field, enabling greater resource allocation and intensified research activity, as reflected in a hike in publication growth rates and the later introduction of marketed products. Thus expanded research activity eventually led to the 1959 MOS-FET design as the transistor’s dominant design used in large-scale dissemination such as in modern computer chips. Consequently, I propose to view the transistor as an emerging invention – in contrast to a discrete or singular one – with an emergence period spanning several decades. I propose to distinguish between an exploration phase (~1920-1945), a consolidation phase (1945-1950), and a maturation phase (1950-) whereas the intermediate consolidation phase represents a topological transition as is characteristic of emerging fields. Another emphasis of this article lies on the role of informal knowledge in the invention process. In the transistor case, such informal knowledge included patent specifications with proposed device designs, amateur radio magazine articles with reported anomalies, and oral anecdotes in practitioner circles describing experimental configurations of interest. This research asserts that such kinds of informal knowledge played an important role early on in the invention process as they guided both early research campaigns and managerial decisions, including at Bell Labs.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84822729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper promotes the intention of infrastructure in an urban scenario and studies the performance of routing protocols considering the constraint of mobility. This leads us to analyze a wide range of routing protocols to ensure optimal coverage and continuous connectivity, taking into consideration two types of data traffic in realistic environments that depend on certain performance metrics.

The turbojet engines have higher main-shaft speeds operating at elevated temperature conditions, reducing the bearing estimated life and thus the need of schedule maintenance. This system can identify some of the bearing damages like cracks, dents, fatigue, fretting and smearing conditions prevailing due to thermal effects, high axial and radial loads over the main-shaft, propeller shank and auxiliary systems bearings. It finally assists the aircraft maintenance engineers and technicians to reach to the conclusions of bearing conditions by taking pictures of bearings from any device and fetching them to the system for better results of bearing conditions.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89453216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, researchers have mainly focused on individual-level drivers of behaviors in communities, while downplaying (formal, informal) context at various levels. We theorize that different dimensions of context (i.e. omnibus and discrete context) influence decision-making in online communities through mechanisms involving community members’ attention. Specifically, context influences which problems members perceive and which solutions they retrieve and apply, thereby shaping the process of matching solutions and problems. We derive four hypotheses about contribution behaviors in online communities and how such behaviors are influenced by context. The empirical setting for our study is the open-source software community.

To this end, fundamental theoretical principles, thermodynamic and kinetics modeling, and existing literature data are employed. Two different AM processes, namely, laser-directed energy deposition and electron-beam powder-bed fusion are considered. The general aspects of phase formation during solidification and solid state in Alloy 718 are first examined, followed by a detailed discussion on phase transformations during the two processes and subsequent standard post heat-treatments. The effect of cooling rates, thermal gradients, and thermal cycling on the phase transformation in Alloy 718 during the AM processes are considered. Special attention is given to illustrate how the segregated composition during the solidification could affect the phase transformations in the Alloy 718. The information provided in this study will contribute to a better understanding of the overall process–structure–property relationship in the AM of Alloy 718 718.","PeriodicalId":89488,"journal":{"name":"The electronic journal of human sexuality","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73886028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
