IT in lean-based manufacturing industries: systematic literature review and research issues

This systematic literature review is the first to explore the role of IT in lean manufacturing contexts, characterising literature on the field, identifying and exploring the main issues approached, and identifying potential future lines of research. Grounded on an accurate screening process, 124 papers were selected for analysis from the SCOPUS and the ISI Web of Knowledge databases. The structured content analysis process highlights five key issues approached in literature: (1) software and technologies used, (2) benefits achieved through applying IT in lean manufacturing, (3) importance of IT integration, (4) IT and lean as complementary or independent options and (5) role of human resources. Despite an apparent scepticism concerning compatibility between IT and lean, claiming that IT may lead to processes’ complexity, extra tasks, resource consuming, among other issues, among other key findings, the review shows that several different IT instruments may boost improvements, acting as a facilitator in developing lean industrial environments, especially when lean-based improvement processes are introduced first, and then IT infrastructures. Because both IT and Lean may require significant investments in terms of managerial attention, employees’ capabilities and financial resources, it is important for management to balance investment decisions. Authors point to several shortcomings in literature which represent significant opportunities for further research: (1) significant lack of integrated comprehensive frameworks, (2) lack of knowledge concerning hybrid manufacturing systems, supply chains as research unit of analysis, how organisations can respond to staff resistance, and role of IT across the distinctive stages of lean maturity.

Nonlinear optical response of triple-mode silicon photonic crystal microcavities coupled to single channel input and output waveguides

Optical and opto-electronic components play important roles in both classical and quantum information processing technologies. Despite fundamental differences in these technologies, both stand to benefit greatly from moving away from bulky, individually packaged components, toward a scalable platform that supports dense integration of low power consumption devices. Planar photonic circuits, composed of devices etched in a thin slab of high refractive index material, are considered an excellent candidate, and have been used to realize many key components, including low-loss waveguides, light sources, detectors, modulators, and spectral filters. In this dissertation, a novel triple-microcavity structure was designed, externally fabricated, and its linear and nonlinear optical properties were thoroughly characterized. The best of the structures exhibited both high four-wave mixing conversion efficiencies and low threshold optical bistability, which are relevant to frequency conversion and all-optical switching applications. The device consisted of three coupled photonic crystal (PC) microcavities with three nearly equally spaced resonant frequencies near telecommunication wavelengths (λ ∼ 1.5 μm), with high quality factors (∼ 105, 104 and 103). The microcavity system was coupled to independent input and output PC waveguides, and the cavity-waveguide coupling strengths were engineered to maximize the coupling of the input waveguide to the central mode, and the output waveguide to the two modes on either side. A novel and sophisticated measurement and analysis protocol was developed to characterize the devices. This involved measuring and modelling the linear and nonlinear transmission characteristics of each of the modes separately with a single tunable laser, as well as the frequency conversion efficiency (via stimulated four-wave mixing) when two tunable lasers pumped two of the modes, and the power generated in the third mode was monitored. Comparisons of the entire set of model and experimental results led to the conclusion that this
MARKET OPPORTUNITIES and REGULATORY FRAMEWORK CONDITIONS for STATIONARY BATTERY STORAGE SYSTEMS in GERMANY

District heating networks are commonly addressed in the literature as one of the most effective solutions for decreasing the greenhouse gas emissions from the building sector. These systems require high investments which are returned through the heat sales. Due to the changed climate conditions and building renovation policies, heat demand in the future could decrease, prolonging the investment return period. The main scope of this paper is to assess the feasibility of using the heat demand – outdoor temperature function for heat demand forecast. The district of Alvalade, located in Lisbon (Portugal), was used as a case study. The district is consisted of 665 buildings that vary in both construction period and typology. Three weather scenarios (low, medium, high) and three district renovation scenarios were developed (shallow, intermediate, deep). To estimate the error, obtained heat demand values were compared with results from a dynamic heat demand model, previously developed and validated by the authors. The results showed that when only weather change is considered, the margin of error could be acceptable for some applications (the error in annual demand was lower than 20% for all weather scenarios considered). However, after introducing renovation scenarios, the error value increased up to 59.5% (depending on the weather and renovation scenarios combination considered). The value of slope coefficient increased on average within the range of 3.8% up to 8% per decade, that corresponds to the decrease in the number of heating hours of 22-139h during the heating season (depending on the combination of weather and renovation scenarios considered). On the other hand, function intercept increased for 7.8-12.7% per decade (depending on the coupled scenarios). The values suggested could be used to modify the function parameters for the scenarios considered, and improve the accuracy of heat demand estimations.
Private standards for animal welfare in Austrian dairy husbandry: Consequences for farmers in mountain regions

The current shift of regulations for animal welfare from public to private standards allows dairies and retailers to improve their position on the market. However, for easy communication and control they tend to reduce the multifaceted societal demands for animal welfare to freedom of movement, that is, to free stalls with or without access to pasture. Taking a farmers perspective, this contribution examines the situation in Austria, where structure and practices of dairy farming differ greatly between more favourable, arable, and mountainous regions. The theoretical concept of farming styles uncovers fundamental positions grounded in different understandings of how farming practices are supposed to be organized. Private standards privilege rationalized, large-scale dairy farms in advantaged regions over family-owned traditional farms in mountain areas. This may have unintended negative consequences on farming structure, land use and cultural landscape.
Do Characteristics And Political Background Of Regional Heads Influence Financial Performance Of Local Governments In Indonesia?

The present research aims at examining the influence of characteristics and political background of regional heads on financial performance of local governments in Indonesia. The population in the present research includes local governments in Indonesia. The samples are second level of local governments in Java. The total number of final samples is 112. Data comprise the APBD realization reports, data fromofficial websites of local governments, and data from official website of the Local Government Election Commission. Panel data regression was employed for data analysis. The results of the present studyindicate that educational background and level of education exert an influence on financial performance of local governments. Meanwhile, tenure, age, and political background do not have a significant influence on financial performance of local governments. The present research was only conducted at second level of local governments in Java in 2016—2018. The present research gives contribution to the literature of local government performance, especially from the perspectives of financial performance of second level local governments in Java Island. Research on the use of political background has rarely been conducted to assess financial performance of local governments.

Effects of Aqueous and Ethanolic Extract of Rhazya stricta on Control of Date Contamination Under in vitro Conditions

Background: Contamination of tissue culture medium is a common problem that causes the loss of some or all cultures. Despite all measures taken in tissue culture laboratories to prevent culture contamination, bacterial and fungi contamination is still a significant problem under in vitro culture. Achieving a suitable method for controlling the contaminants in the in vitro culture medium will be a considerable development in the micropropagation of dates. Objectives: We aimed to investigate the effects of different aqueous and ethanolic extracts of Rhazya stricta on the disinfection of dates under in vitro culture. Methods: A factorial test was performed based on a completely randomized design with three replications. The study included three factors: plant organs (leaves and roots), solvent type (ethanolic and aqueous), and extract concentration (0, 25, 50, and 75 mg/mL). Results: The lowest contamination (38.33%) was seen in the treatment with ethanolic root extract (50 ppm). In comparison, the control and the treatment containing aqueous leaf extract (with concentrations of 0 and 25 ppm) resulted in the highest contamination rate (100%) in tissue culture conditions. Conclusions: The alcoholic extract of medicinal plants can be used to disinfect the explants and the substrate.
Trace‐element heterogeneity in rutile linked to dislocation structures: Implications for Zr‐in‐rutile geothermometry

The trace‐element composition of rutile is commonly used to constrain P–T–t conditions for a wide range of metamorphic systems. However, recent studies have demonstrated the redistribution of trace elements in rutile via high‐diffusivity pathways and dislocation‐impurity associations related to the formation and evolution of microstructures. Here, we investigate trace‐element migration in low‐angle boundaries formed by dislocation creep in rutile within an omphacite vein of the Lago di Cignana unit (Western Alps, Italy). Zr‐in‐rutile thermometry and inclusions of quartz in rutile and of coesite in omphacite constrain the conditions of rutile deformation to around the prograde boundary from high pressure to ultra‐high pressure (~2.7 GPa) at temperatures of 500–565°C. Crystal‐plastic deformation of a large rutile grain results in low‐angle boundaries that generate a total misorientation of ~25°. Dislocations constituting one of these low‐angle boundaries are enriched in common and uncommon trace elements, including Fe and Ca, providing evidence for the diffusion and trapping of trace elements along the dislocation cores. The role of dislocation microstructures as fast‐diffusion pathways must be evaluated when applying high‐resolution analytical procedures as compositional disturbances might lead to erroneous interpretations for Ca and Fe. In contrast, our results indicate a trapping mechanism for Zr.
A single-nucleus transcriptomic atlas of the dog hippocampus reveals the potential relationship between specific cell types and domestication

Abstract The process of domestication has led to dramatic differences in behavioral traits between domestic dogs and gray wolves. Whole-genome research found that a class of putative positively selected genes were related to various aspects of learning and memory, such as long-term potentiation and long-term depression. In this study, we constructed a single-nucleus transcriptomic atlas of the dog hippocampus to illustrate its cell types, cell lineage and molecular features. Using the transcriptomes of 105 057 nuclei from the hippocampus of a Beagle dog, we identified 26 cell clusters and a putative trajectory of oligodendrocyte development. Comparative analysis revealed a significant convergence between dog differentially expressed genes (DEGs) and putative positively selected genes (PSGs). Forty putative PSGs were DEGs in glutamatergic neurons, especially in Cluster 14, which is related to the regulation of nervous system development. In summary, this study provides a blueprint to understand the cellular mechanism of dog domestication.
Socio-economic and Morpho-biometric Characteristics of the Aftout Camel (Camelus dromedarius) in the Trarza Region of Mauritania

Camels are critically important in the Mauritanian culture and traditions. The study was conducted in May and June 2017 in fifteen localities of two departments of Trarza in Mauritania. The objective was to characterize Aftout camel population from socio-economic and morpho-metric characteristics. A questionnaire was administered to 25 breeders in the study area. Nine morpho-metric measurements were recorded on 104 camels aged 6 years or above. The study showed that camel keeping is a typical men’s activity. All the investigated breeders were men, among which 68% are more than 45 years age, and 84 % has never attended formal education. 80% of the breeders have practiced camel rearing for more than 20 years. The activity was considered a major one, as it contributes more than 75% of the family income for 76% of the breeders. The average zootechnic performances were 5.28±1.64 l/d, 3.48±1.15 years, 5.04±0.84 years, 1.38±0.58 years and 1.6±0.40 years respectively for milk production, age at reproduction of females, age at reproduction of males, age at weaning and duration of lactation. The studied biometric measurements highlighted a marked variability. Four morpho-zoometric indices were estimated, and the average estimated body weight was 352.41±55.12 kg. Based on the obtained results, Aftout camel was characterized by a large diversity of practices, which may be an asset for identifying and orienting the productive potential of various camel types in Mauritania.
Variable stars in the globular cluster M53

We present preliminary results obtained from analysis of the VI photometry of the globular cluster M79. Stellar variability survey performed with the image subtraction method yielded six new pulsating stars: two of RR Lyrae type, three SX Phoenicis stars and even one W Virginis star. Using all eleven RR Lyrae stars known in the cluster we find that M79 is Oosterhoff type II globular cluster.
Integrated Perceptual Decisions Rely on Parallel Evidence Accumulation

Summary The ability to make accurate and timely decisions, such as judging when it is safe to cross the road, is the foundation of adaptive behaviour. While the computational and neural processes supporting simple decisions on isolated stimuli have been well characterised, in the real-world decision-making often requires integration of discrete sensory events over time and space. When crossing the road, for example, the locations and speeds of several cars must be considered. It remains unclear how such integrative perceptual decisions are regulated computationally. Here we used psychophysics, electroencephalography and computational modelling to understand how the human brain combines visual motion signals across space. We directly tested competing predictions arising from influential serial and parallel accounts of visual processing. Using a biologically plausible model of motion filtering, we find evidence in favour of parallel integration as the fundamental computational mechanism regulating integrated perceptual decisions.
Using iron line reverberation and spectroscopy to distinguish Kerr and non-Kerr black holes

The iron Kα line commonly observed in the X-ray spectrum of both stellar-mass and supermassive black hole candidates is produced by the illumination of a cold accretion disk by a hot corona. In this framework, the activation of a new flaring region in the hot corona imprints a time variation on the iron line spectrum. Future X-ray facilities with high time resolution and large effective areas may be able to measure the so-called 2-dimensional transfer function; that is, the iron line profile detected by a distant observer as a function of time in response to an instantaneous flare from the X-ray primary source. This work is a preliminary study to determine if and how such a technique can provide more information about the spacetime geometry around the compact object than the already possible measurements of the time-integrated iron line profile. Within our simplified model, we find that a measurement of iron line reverberation can improve constraints appreciably given a sufficiently strong signal, though that most of the information is present in the time-integrated spectrum. Our aim is to test the Kerr metric. We find that current X-ray facilities and data are unable to provide strong tests of the Kerr nature of supermassive black hole candidates. We consider an optimistic case of 105 iron line photons from a next-generation data set. With such data, the reverberation model improves upon the spectral constraint by an order of magnitude.
Spatiotemporal variation of urban thermal environment and its relationship with urban expansion types from 2000 to 2020: a case of Huai’an central urban area, Huai’an, China

Abstract It is critically important to understand the variation of urban thermal environment since urban heat island (UHI) effect is one of the most worrisome urban environment and impedes urban sustainable development. Taking Huai’an central urban area in China as a case, Landsat images from 2000 to 2020 were used, we first estimated land surface temperature (LST) and land covers based on google earth engineer (GEE) platform. Then explored annual variation of SUHI and urban expansion types using statistics method and urban landscape Analysis tools. Finally, discussed the heat effect of urban expansion types and directions. The results showed that (1) SUHI patches gradually concentrated in Phase I, while in Phase II, concentrated SUHIs spread continuously from urban centre to rural area, changing from two centres to a polycentric pattern. (2) Urban expansion was characterized as a diffusion and coalescence process, extension type is the most dominant urban growth mode, second is leapfrog type, and the smallest is infilling type. (3) Annual trend of NLST shows an increasing trend for all three urban expansion types during the last two decades, which of extension mode was biggest, while, that of infilling growth was smallest. This research can attribute a better understanding for the impact of urban expansion on surface heat island effects.
