A deep attention based approach for predictive maintenance applications in IoT scenarios

PurposeThe recent innovations of Industry 4.0 have made it possible to easily collect data related to a production environment. In this context, information about industrial equipment – gathered by proper sensors – can be profitably used for supporting predictive maintenance (PdM) through the application of data-driven analytics based on artificial intelligence (AI) techniques. Although deep learning (DL) approaches have proven to be a quite effective solutions to the problem, one of the open research challenges remains – the design of PdM methods that are computationally efficient, and most importantly, applicable in real-world internet of things (IoT) scenarios, where they are required to be executable directly on the limited devices’ hardware.Design/methodology/approachIn this paper, the authors propose a DL approach for PdM task, which is based on a particular and very efficient architecture. The major novelty behind the proposed framework is to leverage a multi-head attention (MHA) mechanism to obtain both high results in terms of remaining useful life (RUL) estimation and low memory model storage requirements, providing the basis for a possible implementation directly on the equipment hardware.FindingsThe achieved experimental results on the NASA dataset show how the authors’ approach outperforms in terms of effectiveness and efficiency the majority of the most diffused state-of-the-art techniques.Research limitations/implicationsA comparison of the spatial and temporal complexity with a typical long-short term memory (LSTM) model and the state-of-the-art approaches was also done on the NASA dataset. Despite the authors’ approach achieving similar effectiveness results with respect to other approaches, it has a significantly smaller number of parameters, a smaller storage volume and lower training time.Practical implicationsThe proposed approach aims to find a compromise between effectiveness and efficiency, which is crucial in the industrial domain in which it is important to maximize the link between performance attained and resources allocated. The overall accuracy performances are also on par with the finest methods described in the literature.Originality/valueThe proposed approach allows satisfying the requirements of modern embedded AI applications (reliability, low power consumption, etc.), finding a compromise between efficiency and effectiveness.

Unmanned Aerial Vehicle (UAV)-Based for Slope Mapping and the Determination of Potential Slope Hazard

This paper discusses the applications of unmanned aerial vehicle (UAV) for slope mapping and the determination of potential slope hazard of three selected areas. With the development of modern technology, the utilization of UAV to gather data for slope mapping can be considered as finest method as it is quick, reliable, precise, cost-effective and also easily to operate. High imagery quality is essential for the effectiveness and nature of normal mapping output such as Digital Surface Model (DSM) and also Ortho Images. The utilization of UAV to capture aerial photo helps to gather information from a normal area to an area which almost impossible to reach. With the data obtained by the UAV, it will later process in established software and the analysis of slope profile of certain selected study areas will be done. Mapping using UAV was within the area of Pahang Matriculation College. Three slope area namely as Area 1, Area 2 and Area 3 are marked. Further analyses are conducted in these three areas to obtain the information of potential slope hazard based on slope angles. For Area 1, the slope is marked at the coordinate of (286136.265, 412066.821) to (286265.423, 411783.038). The slope angle between the two vertexes was 46.18° and considered as very steep slope. For Area 2, the slope is marked at the coordinate of (286054.203, 412021.343) to (285963.651, 411913.543). The slope angle between the two vertexes was 77.66° and considered as very steep slope. The slope at Area 3 is marked at the coordinate of (285847.833, 411775.762) to (285887.450, 411251.046). The slope angle between the two vertexes was 47.43° and considered as very steep slope. In conclusion, the use of UAV in geotechnical engineering proven to be very useful for slope mapping and determination of slope hazard based on slope angle.

Islamophobia as Cultural Racism: The Case of Islamic Attire in Turkey

Grasping the various aspects of Islamophobia in Muslim societies requires much finer methods in order to decipher the intentions of the actors in distinctive life situations varying from the media to education. This article engages in a debate as to whether Islamophobia is a new type of racism, i.e., cultural, geographical, phenotypical, or Xeno-racism, and the relatively recent type that has emerged in neo-liberal states: anti-Muslim racism. In a Muslim-majority society, the ‘culture’ of members is fairly homogenous, so Islamophobia takes another cue, focusing on external markers, like the headscarf or beard. While anti-Muslim racism is sometimes exercised along more subtle lines of cultural difference in Muslim societies, it prevails through old-fashioned, phenotypical racism. The representation or rather misrepresentation of Islam and/or Muslims in the media can be understood as the prevailing source of antagonism between the secular and the traditionalist segments of Turkish society; indeed, Turkish media representation produces and reproduces a racialization of the majority, predominately by rendering Islam invisible, or by depicting Muslims in ways that denigrate their clothing, manners, style, and way of living across various mass media forms.

Graphene oxide as Nano material in high strength self-compacting concrete

The Particles with dimensions less than 100 nm are considered as Nano materials. These Nano materials have the ability to modify elements at Nano scale. By modifying cement at Nano scale, we can improve the micro structure of cement. One such Nano material is Graphene Oxide (GO). GO is incorporated in high strength self-compacting concrete (HSSCC) to improve the performance characteristics. HSSCC is the new age material in the fast growing construction industry. There are various methods to produce HSSCC, one finest method among them is by improving the microstructure of cement using Graphene oxide. It is an advanced Nano material which achieved significant levels in various fields. This paper investigates the rheological and mechanical properties of GO incorporated high strength self-compacting concrete. The percentage increase of Compressive strength, tensile strength and flexural strength was observed to be 17%, 40% and 28% respectively. GO is added to cement at contents 0, 0.02, 0.04, 0.06, 0.08 and 0.1% by weight of powder to determine the achieve High strength self-compacting concrete. Rheological and mechanical properties of HSSCC are determined at 7, 28, 56 and 90 days of curing.

Precise and Parallel Pairwise Metagenomic Comparisons

The comparison and assessment of similarity across metagenomes are still an open problem. Uncultivated samples suffer from high variability, thus making it difficult for heuristic sequence comparison methods to find precise matches in reference databases. Finer methods are required to provide higher accuracy and certainty, although these come at the expense of larger computation times. Therefore, in this work, we present our software for the highly parallel, fine-grained pairwise alignment of metagenomes. First, an analysis of the computational limitations of performing coarse-grained global alignments in parallel manner is described, and a solution is discussed and employed by our proposal. Second, we show that our development is competitive with state-of-the-art software in terms of speed and consumption of resources, while achieving more accurate results. In addition, the parallel scheme adopted is tested, depicting a performance of up to 98% efficiency while using up to 64 cores. Sequential optimizations are also tested and show a speedup of 9× over our previous proposal.

Pre‐Actuation and Optimal State Transition Based Precise Tracking for Maximum Phase System

AbstractPrecise trajectory tracking for the maximum phase system can be achieved by the stable inversion method. However, its side effect is requiring the sufficient extended zero trajectory. To overcome this drawback, firstly, this paper introduces the concept of stable initial state which is of vital importance to achieve precise output tracking. And then several methods have been presented to obtain the stable initial state. Both the standard method and the pre‐actuation method can be seen as the simplified stable inversion method under certain conditions, but the two methods only perform approximate output tracking. To achieve precise trajectory tracking, the optimal state transition method and the combination method consisting of the pre‐actuation and the optimal state transition are introduced. Finally, the optimal combination method is proposed to obtain the best overall tracking effect. In brief, different methods are fit for different situation but the optimal combination method is the finest method in practical situation. The effectiveness of the proposed methods are verified through numerical simulations for the maximum phase system.

Exact solution of a master equation applied to the two-level system of an atom

In this paper we discuss a master equation applied to the two-level system of an atom and derive an exact solution to it in an abstract manner. We also present a problem and a conjecture based on the three-level system. Our results may give a small hint to understand the huge transition from Quantum World to Classical World. To the best of our knowledge this is the finest method up to the present.

Third-Order Leader-Following Consensus in a Nonlinear Multiagent Network via Impulsive Control

Many facts indicate that the impulsive control method is a finer method, which is simple, efficient, and low in cost, for achieving consensus. In this paper, based on graph theory, Lyapunov stability theory, and matrix theory, a novel impulsive control protocol is given to realize the consensus of the multiagent network. Numerical simulations are performed to verify the theoretical results.

Design of Ligand Binding to an Engineered Protein Cavity Using Virtual Screening and Thermal Up-shift Evaluation

Proteins could be used to carry and deliver small compounds. As a tool for designing ligand binding sites in protein cores, a three-step virtual screening method is presented that has been optimised using existing data on T4 lysozyme complexes and tested in a newly engineered cavity in flavodoxin. The method can pinpoint, in large databases, ligands of specific protein cavities. In the first step, physico-chemical filters are used to screen the library and discard a majority of compounds. In the second step, a flexible, fast docking procedure is used to score and select a smaller number of compounds as potential binders. In the third step, a finer method is used to dock promising molecules of the hit list into the protein cavity, and an optimised free energy function allows discarding the few false positives by calculating the affinity of the modelled complexes. To demonstrate the portability of the method, several cavities have been designed and engineered in the flavodoxin from Anabaena PCC 7119, and the W66F/L44A double mutant has been selected as a suitable host protein. The NCI database has then been screened for potential binders, and the binding to the engineered cavity of five promising compounds and three tentative non-binders has been experimentally tested by thermal up-shift assays and spectroscopic titrations. The five tentative binders (some apolar and some polar), unlike the three tentative non-binders, are shown to bind to the host mutant and, importantly, not to bind to the wild type protein. The three-step virtual screening method developed can thus be used to identify ligands of buried protein cavities. We anticipate that the method could also be used, in a reverse manner, to identify natural or engineerable protein cavities for the hosting of ligands of interest.

Rheological properties of an apatitic bone cement during initial setting.

One scientific and technological aspect of main importance to the medical profession is to develop injectable calcium phosphate cements (CPCs) to be used through minimally invasive surgery techniques with still suitable mechanical and biodegradable properties. The objective of this research was to study the influence of several technological factors on the injectability of CPCs. This was performed by studying the rheological behavior of the cement pastes during their initial setting. Cement rheology was approached by looking at the creep response of apatitic cements as a function of the shear stress, the liquid-to-solid (L/S) ratio, the temperature and the addition of organic admixtures. Results showed creep experiments to be a finer method to detect characteristic setting times than other established subjective procedures. However, of all transition times detected none but the dough time seems to be of relevant importance when injectability of cement is concerned. Creep experiments also showed that the addition of organic admixtures such as citric acid increased injectability by retarding the hydration time.

Location of the zeros of polynomials satisfying three-term recurrence relations with complex coefficients

Two papers on the same subject were pubkushed by the authors in 1985:part I[1]and part III[2].The method announced for part II did not give satisfying results.However,we noticed that our method of estimationg the boundaries of zero-free regions for polynomials can be improved by introducing proper optimizing paramcters for each polynomial.The optimization is then performed over all these parameters at the end. It was showed that this finest method of optimimation is sharp in the following sense:it leads to the exact interval where all zeros of classical orthogonal polynomials are licated[3].In the present paper we give the complete proofs of these improved theorems of lication in quaestion.

Standard models for some commuting multioperators

An analogue to the Sz.-Nagy-Foia5 dilation theory is presented for several commuting operators on a Hilbert space. The dilation theory of Hilbert space contractions, a reference of which is the excellent monograph [9], has not yet found a complete counterpart valid for several (commuting) Hilbert space operators. Apart from the results of this type already contained in [9] and other results of general character (i.e., Arveson's or Stinespring's extension theorem), there are not too many contributions specialized to the multiparameter dilation theory. Among these contributions, we quote the works [7, 3-5, 10], which are closer to our topics. The aim of this paper is to analyse some positivity conditions for commuting multioperators, which ensure the unitary equivalence of these objects to some standard models consisting of backwards multishifts. We emphasize, in particular, a situation that seems to satisfy the requirements of an appropriate extension for the dilation theory of Hilbert space contractions and that exploits the results already obtained in [4, 10]. Our finer methods also imply better statements of some assertions from [10] and provide an answer to Question 4.5 from [5]. Let n > 1 be an integer, and let Zn be the set of all n-tuples of nonnegative integers (i.e., the multi-indices of length n). If a = (a, ...I, an) E Zn+, we set, as usual, lal =a,+ + -+a, and a! =a1! .. !. For a,ficZ+ wewrite a + f = (a1 + f1j ... , an + fin), and a < fi whenever aci < /i (i = 1, ... , n). Let H be a Hilbert space, and let 2(H) be the algebra of all bounded linear operators on H. An element T = (T,, ... , T,) E 2(H)n such that T,, ... , T, mutually commute will be designated as a commuting multioperator (briefly, a c.m.). Let T E Y(H)n be a c.m. We define the operator MT: Y(H) -* J(H) by the formula

Modern Technique in Historical Development

We are all aware that the teaching of history today has become a very problematical affair—due as much to the subject as to our times. For centuries and up to a few generations ago the situation was different. In former days the center of gravity of instruction was in ancient history; and this proved itself a magnificent medium for the education of youth. For the history of the Greek-Roman world is understandable to young people as no other area of history; and the ancient historians dispense with the details which preoccupy the moderns. Ancient history is constricted. It can be surveyed completely from its impenetrable dark beginnings to its definitive expiration. We look across the stage from the required distance. The extant source material is limited and of high intellectual content, not loaded up with state proceedings of kingdoms and principalities; the entire development culminates in the two high points—Athens and Rome—and unites them in magnificent harmony. As peers to their subject, the ancient historians have a taste for grand scenes, a taste for the wide contours of world history, for the simplicity and good proportions of form. They do not give too much criticism. They write as moralists and have their firm point of view. They present the universally human, the typical, man and his emotions, not mayhap the individual and his local surroundings; thus as depicted their people remain allied to us; everything can be surveyed and is even accessible to youth without further ado. Ancient history is less fertile than modern, but it is also less full of underbrush. Mighty strides have been made in historical studies since the last century; yet the newer kind is bought with sacrifices. The spirit of criticism has developed the finest methods. Every event of the past has become thoroughly complicated, burdened with controversies; in addition the results shift constantly. Nothing seems to be secure in history. And the spirit of individualization, without which a consideration of historical life can no longer exist, forces us to busy ourselves with the most diverse objects, so that the large outlines are obscured thereby and the integrity of events remains ambiguous.

CONGENITAL ESSENTIAL THROMBOPENIC PURPURA

As a preliminary to reporting this case of congenital thrombopenic purpura, it seemed pertinent to review the literature in order to determine whether the criteria for a correct diagnosis had been fulfilled in every instance of so-called congenital thrombopenic purpura. Perusal of the literature revealed the fact that thirteen observers had reported cases of this disease. These cases were scrutinized carefully, observing the criteria which will be noted here. Since the advent of new procedures, in the last decade, finer methods of study in the hemorrhagic tendencies have been utilized. These include study of the megakaryocytes in the bone marrow and estimation of the prothrombin level. In all fairness to previous reports, diagnosis made by authors without benefit of bone marrow and prothrombin determinations have been accepted if the rest of the findings made the diagnosis plausible. In the future, however, much can be gained by adhering to the criteria
