Deep Learning in the Maintenance Industry

The work hereby presented was born from a desire to find how modern machine learning methods can be applied to improve scheduling in the maintenance industry. Efficient scheduling is a daily challenge in the maintenance industry. This industry deals with planned maintenance and daily requests for repairs. Commercial building maintenance work is regularly needed due to deterioration, accidents on the premises or legal requirements for building compliance. Efficient scheduling is a daily challenge in this industry. The scheduling must account for variable workload, variable workforce and variable task duration. In our research, we leverage recent developments in Machine Learning to provide additional information that can aid human operators to make informed decisions when scheduling. We take the approach of using AI to improve human lives instead of replacing human workers. To this end, we propose two methods: • Forecasting workload. • Task classification into short/long duration based on the task’s text description. Solving these tasks would aid the human operator to create a more efficient work plan, optimizing human resources and reducing overwork due to poor scheduling. Our results show that we were able to train skilful models for forecasting workload, which greatly improved on the baselines. We employ recent innovations in Natural Language Processing such as word vectors and attention mechanisms to achieve notable results in classifying tasks, creating models capable to outperform human performance at the task.
Electronic Structure and Photoluminescence Origin of Single-Crystalline Germanium Oxide Nanowires with Green Light Emission

High-quality single-crystalline germanium oxide nanowires (GeONWs) have been synthesized by a thermal evaporation method under a vapor–liquid–solid mechanism. The morphology and nanostructure of the as-synthesized GeONWs were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Energy-dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) of the GeONWs showed the presence of substoichiometric oxygen. The electronic structure and local structure of GeONWs were also investigated by X-ray absorption fine structure (XAFS), which showed disorder and degradation of long-range order in the nanowires due to the nanosize in one-dimension and oxygen vacancies in the nanowires. Synchrotron-radiation-based X-ray-excited optical luminescence (XEOL) from GeONWs exhibits strong green light at 2.3 eV (540 nm), which corresponds to the photoluminescence (PL) spectrum of the individual GeONWs excited by laser. The strong emission i.

Preparation and characterization of a new polyaniline salt with good conductivity and great solubility in dimethyl sulfoxyde

In this study, we propose a novel conducting and soluble polyaniline salt prepared by chemical polymerization in the presence of new doping agent (IAs). This last is prepared by sulphonation of itaconic acid (IA) with concentrated sulphuric acid in THF. The obtained doped polyaniline (PANI-IAs) is extremely soluble in dimethyl sulfoxyde (DMSO) at room temperature, in which the solubility reach 44 mg mL -1 . The conductivity measurement of doped polyaniline powder precipitated in THF as dispersing medium gave a value of 0.13 S cm -1 when the emeraldine base form of polyaniline is fully protonated. The polyaniline salt sample is characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction, UV-Visible spectra and FTIR spectra.
Evaluation of 20 toxic metals and essential elements in the blood of metal recycling tinsmiths of Cotonou (Benin)

It is common for trainees and craftsmen in the informal economy to not use protective equipment. With tinsmiths, exposure to toxic emissions such as fumes of molten metal that may contain metallic particles is likely to lead to uptake of toxic metals. Aims: The principal aim of this study was to evaluate the biological concentrations of toxic metals and essential trace elements in tinsmiths, craftsmen, and trainees working in the informal sector of Cotonou in Benin. Materials and Methods: Twenty metallic trace elements were measured in whole blood from 111 adult male tinsmith craftsmen, while only the blood lead level was measured in twenty-four trainees of less than 18 years of age. The blood samples were collected at the ERASME health center of Cotonou, using 6 ml EDTA-K2 trace element tubes. The analyses were performed by ICP-MS (Inductively Coupled Plasma-Mass Spectrometry) with a NexION 350 D (PerkinElmer) spectrometer. The results obtained were then compared to those obtained with a reference population that was not subject to professional exposure. Results: For three trace elements, more than 25% of the adult tinsmiths exhibited blood concentrations above the biological reference values. By increasing order of uptake, these were antimony (28.8%), tin (31.5%), and lead (71.2%). For trainees under 18year of age, the prevalence of workers with a blood lead level ≥ 100 µg/L was 83%. Conclusions : Exposure to lead was the greatest concern, and protection and awareness measures should be implemented so as to decrease the health risks linked to lead exposure, particularly among young workers.
The Link Between Causal Attribution and Recovery Satisfaction in Mobile Money Transaction Failures: The Mediating Role of Negative Emotions

Purpose – Despite the remarkable growth and importance of mobile money technology, there are reported concerns about transaction failures. This research study evaluates customer perception of and response to trans- action failures and recovery in an emerging market context. Specifi cally, the study proposes a model to analyze the direct eff ect of causal attribution of mobile money transaction failure, employing dimensions of control- lability and stability on recovery satisfaction as well as indirect eff ects through negative emotions. Design/methodology/approach – Data were collected through an online survey using a structured questionnaire on 344 mobile money subscribers who experi- enced transaction failures in the past six months. Findings and implications – The hypotheses of this research study were tested using Partial Least Squares Structural Equation Modeling (PLS-SEM) in SmartPLS 3 software. The study found that both the causal attri- bution dimensions of controllability and stability signifi cantly infl uenced negative emotions and recovery satisfaction. Besides, negative emotions signifi cantly infl uenced recovery satisfaction. The results also re-vealed that negative emotions mediate the relationship between causal attribution and recovery satisfaction. Therefore, service providers are advised to reduce pre-ventable and stable transaction failures. Limitation – Since there was no database of mobile money subscribers who experienced transaction failures, a public online survey with screening questions was employed. Respondents fi lled in the questionnaire based on voluntary response, so care should be employed when generalizing. Originality – This is one of the few studies on service failure in an emerging market. It is the fi rst time that attribution theory has been applied as the main theory to explain the perception of and response to transaction failures in a mobile money setting.
Prevalence of tick infestation of sheep and goats in Bui and Donga-Mantung Divisions of the North West Region of Cameroon

This study was carried out to determine the prevalence, intensity and management systems associated with tick infestation in sheep and goats from Bui and Donga-Mantung Divisions. A total of 704 animals consisting of 342 males and 362 females (463 adults and 241 young (kids/lambs) were physically examined for tick infestation, of which 383 were goats and 321 sheep aged 5 months to 7 years. Of the 704 animals examined, 651 were found positive with one or more ticks giving an overall prevalence of 92.5%. The highest prevalence was recorded in sheep (99.4%) while 86.7% was recorded in goats. There was a significant difference (p<0.05) in the prevalence and intensity of tick infestation of these ruminants in the study area. The overall intensity of infestation or tick burden was 1302 with the highest intensity observed in Boophilus geygei (416). Six species of ticks were identified which were Boophilus geygei, Boophilus annulatus, Boophilus decoloratus, Rhipicephalus sanguineus, Hyalomma truncatum and Haemophysalis laechi with a high prevalence recorded for Boophilus geygei (29.5%) and the least recorded for Haemophysalis laechi (8.4%). Adults and females were the most infested compared to young stock and male animals. Concerning the various management techniques, the prevalence of tick infestation was higher in tethered animals (97.8%), followed by free-range grazing animals (89.8%). Animals confined in paddocks had the least prevalence (71.6%). This study provides an important step to reduce animal infestation and minimize economic losses in sheep and goats by providing information that will help farmers of these areas to use strategic treatment methods and medicinal plants to reduce parasite infestations on the animals and also to practice the right traditional management techniques.
Normal intraepithelial lymphocyte counts in duodenal biopsies and histological features of celiac disease among Jordanian adults

Objective: The earliest histopathological feature of celiac disease (CD) is increased intraepithelial lymphocytes (IEL). The aim of this study is to find out the normal IEL count and to describe the histopathological features of CD among Jordanian population. Methods: This retrospective cohort study included 207 patients, 99 with CD cases and 108 normal controls. IEL were counted in all cases and controls. Histopathological features including villous atrophy and crypt hyperplasia were evaluated in CD cases and were classified according to the Modified Marsh classification. A two-tailed t-test was used to compare the means of variables and a P value of <0.05 was considered significant. Pearson correlation was used to measure relationships between histopathological features in CD cases. The cut-off point was suggested as the mean of normal+ 2 standard deviations (SD). Results: The mean number of IEL in normal biopsies is 11.7. The upper limit of normal is 17, this figure (17) is also the mean + 2SDs. There is no statistical difference of the number of IEL between males and females in the normal group (p = 0.54) or the CD group (p = 0.807). The number of normal IEL significantly decreases with higher age of 49 (p = 0.034). Conclusion: Using 17 as a cut-off point is sufficient to detect CD. Higher thresholds result in missing cases. The cut off points of IEL can vary among geographical areas and thresholds should take these differences into account.
A Modified Mini Incision for The Surgery of Parotid Benign Tumor: A Retrospective Analysis of 48 Cases

Background: Parotid neoplasm is a result of inadequate surgical incision during the treatment of head and neck cancers, and most of them are benign tumors. Hence, to explore a new surgical incision for parotid benign tumor in order to minimize the scar size on the premise of guaranteeing the safety of operation.Methods: We conducted a retrospective study of 48 patients who had undergone parotid surgeries from Jan. 01 2008 to Dec. 30 2014 at the department of otolaryngology, Jinshan Hospital of Fudan University. Histopathological examination confirmed benign parotid tumor (Warthin's tumor, pleomorphic adenoma, cysts, and monomorphic adenomas.) in all cases. All patients underwent a mini incision (cutting the skin directly on the surface of the tumor, and the incision was slightly longer than the diameter of the tumor). Results: Among the 48 cases, no recurrence and facial nerve injury were reported during the follow-up period of more than 4 years. Two cases of saliva fistula and one case of temporary facial nerve dysfunction were reported; however, they recovered quickly after symptomatic treatment.Conclusion: Extracapsular dissection is a safe and effective surgical procedure for the treatment of parotid benign tumor, and the postoperative scar is very small.
Synthesis and Characterization of Soft Magnetic Materials NixZn1-xFe2O4 (x = 0,2 – 0,8) Lombok Iron Sand with Co-precipitation Method

The synthesis of soft magnetic NixZn1-xFe2O4 with variations in composition (x = 0,2 – 0,8) by the co-precipitation method has been carried out. The research objective was to determine the effect of x variation on the crystal structure, microstructure, magnetic properties, and density. The samples were characterized by their crystal structure using XRD, microstructure using FE-SEM, magnetic properties using VSM, and physical properties (True Density). The XRD analysis results obtained two phases, the major phase is nickel-zinc ferrite, and Fe2O3 shows as the minor phase. The crystal size increased and the lattice parameters decreased with the increase in nickel content. The results of FE-SEM analysis at x = 0.2 are spherical in shape with an average particle size found about 47.07 nm. The results of VSM analysis showed that the increase in nickel content, the higher the magnetization saturation value, and the super-paramagnetic properties of all samples obtained. The results of the analysis of physical properties show that true density decreases with an increase of nickel content in each sample.

The field experiment was conducted a t f a r m e r ’ s f i e l d for evaluation of different sowing methods with improved variety MACS-1188 of soybean in Junnar block of Pune district during the year 2016 to 2019. The experiment was conducted by involving two treatments namely Flat-bed method of sowing and Broad bed furrow (BBF) method of sowing. Generally Soybean crop is affected due to excessive rainfall or less rainfall during the germination and at important growth stages of crop. The results indicated that per cent change in yield of f lat-bed method by seed drill over BBF seed drill w a s 18.95 per cent. The average yield of soybean was recorded 24.50 q/ha under BBF sowing. Due to drainage of excessive rain water from the f ields, the broad bed furrow method gave best result. Similarly, 30 to 40 per cent saving in irrigation water was recorded with bed furrow method of soybean in comparison with f lood i r r i g a t i o n in controlled plots. Plant height, number of pods per plant, seed yield weight per plant, seed index, seed yield, straw yield and harvest index (%) found higher in b r o a d bed furrow method as compared to flat bed methods. The net return of Rs. 51424/with B:C ratio of 2.90 was achieved under broad bed furrow method of sowing as compared to flat bed method of sowing.

Study on acetylene preparation from coal conversion directly by plasma

To develop an innovative method for directly converting coal into an important chemical material-acetylene, arc plasma technology was applied to the direct conversion of coal. The powdered coal from Datong was injected into a hydrogen-enriched plasma reactor for pyrolysis. The results show that the coal conversion and the acetylene yield and the special energy consumption (SEC) of acetylene are decreased as coal feed rate is increased, but the concentration of acetylene in production gas is increased. The yield of acetylene is not obviously affected by the formation of CO in production gas. Since oxygen can compete with the active atomic carbon, therefore, the high content oxygen in coal is disadvantageous to the formation of acetylene. Under the experimental conditions selected, the coal conversion rate reach 38.42%, the concentration of acetylene in product gas is 9.30% and the selectivity of acetylene in hydrocarbon is above 70% when the coal feed is 5.0 g/s.
PLASMA CHEMISTRY VALUES FOR THE MONKEY (MACACA MULATTA) AFTER A SUPRALETHAL DOSE OF PULSED MIXED GAMMA-NEUTRON RADIATIONS

Abstract : Monkeys (Macaca mulatta) were given a 4-krad midline tissue dose of pulsed mixed gamma-neutron radiations. Chemical analyses of 11 different constituents of plasma were made before irradiation and at 1, 6, and 12 hours postirradiation to evaluate the extent of radiation injury as indicated by changes in the composition of the plasma. A significant increase in the plasma concentration of glutamic-oxalacetic transaminase, total lactic dehydrogenase, creatinine, creatine, and urea nitrogen was found postirradiation. Although some of the constituents of plasma which were found to increase after irradiation were probably from radiosensitive tissue, other tissues such as muscle, not considered radio-sensitive, appear to have been also injured when subjected to this dose of radiation.
Relationships between developmental feedback, intrinsic motivation, and creative personality and performance

Developmental feedback can motivate employees to take chances and be more creative, at least for employees who interpret feedback as support for new ideas. Drawing on cognitive evaluation theory, we examined relationships between developmental feedback, intrinsic motivation, creative personality (e.g., people who describe themselves as inventive and confident rather than cautious and conservative), and creative performance. We predicted that developmental feedback would contribute to employees? intrinsic motivation and further improve their creative performance, especially those who were high in creative personality. The sample included 215 Chinese employees and their direct supervisors from a big science and technology corporation in Beijing, China. Employees? perceptions of developmental feedback from their supervisor were positively related to employees? ratings of their intrinsic motivation and supervisors? ratings of employees? creative performance. Also, intrinsic motivation of employees mediated the relationship between developmental feedback and their creative performance. These relationships were stronger for employees with a highly creative personality.
ZnFe2O4 nanoparticle: Synthesis and photocatalytic activity under UV-vis and visible light

In the present work, the ZnFe2O4 nanoparticle has been successfully synthesized. The obtained sample was characterized by X-ray diffraction (XRD) and emission scanning electron microscopy (FE-SEM) and its optical property were examined by UV-Vis spectrophotometer. FE-SEM revealed that the particle size of the ZnFe2O4 of about 47 nm was synthesized. The photocatalytic performance under UV-Vis and visible light was evaluated by decolorization of congo red (CR) anionic dye solution. The UV-Vis and visible light irradiation source consist of a high pressure mercury lamp 400 W and filament tungsten lamp 100 W respectively. The photocatalytic results show that the ZnFe2O4 sample can degrade (CR) dye solution up to 100% after 30 and 120 min under UV-Vis and visible irradiation respectively.
Computed Tomography-based Patient-specific Biomechanical and Fluid Dynamic Study of Anomalous Coronary Arteries with Origin from the Opposite Sinus and Intramural Course.

BACKGROUND The anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS) constitutes one of the most clinically relevant coronary artery anomalies in adults. Exact pathophysiology and the impact of intramural (IM) course segment stenting in ACAOS with IM course (ACAOS-IM) has not been clarified. We aimed to elucidate the pathophysiology and impact of stenting applying biomechanical and computational fluid dynamics to computed tomography (CT) in patient-specific coronary vessel reconstruction. METHODS We separated coronary artery (left or L-, right or R-) ACAOS-IM into segments (proximal, mid and distal), based on coronary angiography and coronary CT angiography features, in a series of patients at Rovigo General Hospital, Italy, between 1 January 2003 and 1 January 2018. Blood pressure gradient across the coronary circulation, calculated blood flow, vorticity magnitude, wall shear stress (WSS) and IM segment deformation were analysed by simulating exercise, before and after virtual stent implantation. RESULTS In 21 symptomatic patients (13 males, mean age 46.1 ± 8.1 years, L-ACAOS-IM in 9 and R-ACAOS-IM in 12 patients), computational fluid dynamic analysis in both L- and R-ACAOS demonstrated higher basal WSS values in the IM course (9.5 ± 0.2 and 8.6 ± 0.2 Pa for R- and L-ACAOS, respectively), than in the rest of the vessels. These values decreased after stenting. Vorticity magnitude significantly decreased after stenting as well, compared with baseline. Biomechanical deformation analysis revealed not only compression, but also a twisting of the IM segment with a mean distal pressure drop of 32% and 35% in R- and L-ACAOS, respectively, which was corrected by stent implantation. CONCLUSIONS In both L- and R-ACAOS subtypes, the IM segment appeared to be phasically compressed and deformed with a degree of twisting that causes resting and exercise cross-sectional deformation and a drop in distal pressure. Stenting of the IM segment results in normalisation of the flow profile, correction of the IM segment deformation and reverses the drop in pressure, for both variants of ACAOS.
