Exploring the Potential of Distributed Computing Continuum Systems

Computing paradigms have evolved significantly in recent decades, moving from large room-sized resources (processors and memory) to incredibly small computing nodes. Recently, the power of computing has attracted almost all current application fields. Currently, distributed computing continuum systems (DCCSs) are unleashing the era of a computing paradigm that unifies various computing resources, including cloud, fog/edge computing, the Internet of Things (IoT), and mobile devices into a seamless and integrated continuum. Its seamless infrastructure efficiently manages diverse processing loads and ensures a consistent user experience. Furthermore, it provides a holistic solution to meet modern computing needs. In this context, this paper presents a deeper understanding of DCCSs’ potential in today’s computing environment. First, we discuss the evolution of computing paradigms up to DCCS. The general architectures, components, and various computing devices are discussed, and the benefits and limitations of each computing paradigm are analyzed. After that, our discussion continues into various computing devices that constitute part of DCCS to achieve computational goals in current and futuristic applications. In addition, we delve into the key features and benefits of DCCS from the perspective of current computing needs. Furthermore, we provide a comprehensive overview of emerging applications (with a case study analysis) that desperately need DCCS architectures to perform their tasks. Finally, we describe the open challenges and possible developments that need to be made to DCCS to unleash its widespread potential for the majority of applications.
Zeolite Facies and Regional Rank of Bituminous Coals

Abstract Diagnostic analcime-, heulandite-, and laumontite-bearing mineral assemblages from four areas in the Upper Carboniferous and the Permian of New South Wales have been correlated with the rank of the associated coals, represented by the carbon content of vitrinite. The coals are high-volatile bituminous to semi-anthracitic; their vitrinites contain from about 82 per cent up to an estimated 91 per cent carbon. Analcime-quartz is found associated with the lower-rank, the laumontite-rich assemblages with the higher-rank coals. Comparison with a similar correlation in Northern Yakutia (U.S.S.R.) indicates that diagnostic zeolites are not necessarily associated with coals of the same range of rank in different areas. Unlike the occurrence and stability range of burial metamorphic zeolitic assemblages, degree of coalification is probably independent of partial pressures of H2O and CO2: it is controlled mainly by maximum depth of burial, its duration, and the geothermal gradient.
Cascade Model of Monthly Municipal Water Use

A time series model of monthly municipal water use is formulated as a set of equations representing the effects of four factors on water use: trend, seasonality, autocorrelation, and climatic correlation. The parameters of these equations are found by passing the water use time series through a cascade of four transformations; in each transformation the parameters of an equation associated with one factor are statistically determined and the series transformed to remove the effects of this factor. After the last transformation, only a random error series remains. Monthly municipal water use at Canyon, Texas, from 1961–1978 is modeled as an example. The model explains 86% of the variance of this series, divided among the four factors as trend (29%), seasonality (44%), autocorrelation (2%), and climatic correlation (11%). The random error is shown to be normally distributed by a nonparametric procedure characterizing probability families by their density quantile functions.
Communicating Health Impact of Air Pollution

Adverse health effects of air pollution are well established mostly through epidemiological studies, although also toxicology is consistently accumulating findings as to the underlying mechanisms of these effects. Mostly, it seems, these mechanisms are not very specific: inflammatory processes and oxidative stress predominate. Some pollutants also have mutagenic properties making cancer also a plausible health endpoint of exposure to air pollution. But the long lags between exposure and final disease make epidemiological studies in this field very difficult, so direct epidemiological evidence for cancer effects of air pollution is rare. Nevertheless the few existing studies give a consistent and plausible picture. More importantly there are studies that rather than looking at ultimate disease investigate biological effects that might lead to cancer like DNA adducts or chromosome damage. So even for cancer epidemiological evidence is growing. Several reviews have described the health effects of air pollution in more detail, namely reports by the World Health Organization (WHO 2000; 2005; 2006; 2007) and by the Health Effects Institute (HEI 2000; 2003; 2007; 2010). This chapter will not repeat these valuable and extensive summaries but is rather interested in the link between the scientific findings and policy implications. In fact policies do not deal with air pollution per se, but with specific sources of air pollution thus affecting the interests of several influential stakeholders. So from a policy perspective science is not only called to estimate the health effect of ‘air pollution in general’ but the health effects linked to a specific source of air pollution or more precisely a specific incremental change in pollutants production by that specific source. Air pollution always consists of a whole range of pollutants, gaseous and particulate alike. Keeping in mind the little specificity of the air pollutants' toxicity it is not surprising that not one single pollutant alone accounts for the observed effects. Routine monitoring of air quality is usually restricted to some very few indicators (particulate mass and some gases like ozone, nitrogen oxides, sulphur oxide, and carbon monoxide). Simply because of data availability most epidemiological studies describe the association between those indicator pollutants and health risks. But that does not mean that other usually unmeasured pollutants (polycyclic aromatic hydrocarbons, volatile organic compounds, aldehydes, to name but a few) are not similarly relevant in terms of health effects. Particle mass itself is an indicator covering a whole range of particles differing in size, shape and chemical
Depolarization properties of cirrus clouds near the tropopause measured by a lidar at Chung-Li (25 deg N, 121 deg E)

The polarization lidar measurements were carried out to investigate the optical properties of ice crystals. The cloud height, extinction-to-backscattering ratio, optical depth, and depolarization ratio for cirrus clouds in the height range of 10-17 km were analyzed. We found the cloud optical depth has a clear height dependence, with high clouds optically thin. There is an increasing trend of depolarization ratio with height between 12-16 km. There is a clear relationship between the depolarization ratio and the optical depth. For cirrus clouds at heights between 13 and 15 km region, the clouds with optical depths smaller than 0.1 have depolarization ratios about 0.3. Large depolarization ratio (0.6) was found for subvisual clouds of optical depthabout 0.02. Thick clouds with optical larger than 0.1 have an average depolarization ratio about 0.2.
Analyse factorielle lissée et analyse factorielle des différences locales

Nous proposons deux methodes qui permettent de tenir compte, dans une analyse en composantes principales, d'une structure de proximite ou de contiguite definie sur l'ensemble des lignes d'un tableau de donnees. La premiere, l'analyse lissee permet d'analyser les tendances generales des donnees en eliminant les fluctuations locales. La deuxieme, l'analyse des differences locales permet, au contraire, d'analyser ces fluctuations en eliminant les variations generales liees aux positions spatiales. Nous comparons cette derniere a l'analyse locale (cf. Lebard 1984) et a l'analyse en composantes principales pour des unites statistiques correlees (cf. Caussinus 1980)
Thambema thunderstruckae sp. n., the first record of Thambematidae (Isopoda: Asellota) from the Southern Hemisphere shelf

: A new thambematid species, Thambema thunderstruckae sp. n. , is described from King George Island, South Shetland Islands, Antarctic. Specimens of the new species were collected during two Polish Antarctic Expeditions in 1985 and 2007. It is the first re− cord of this family from the Southern Hemisphere. The new species most closely resembles Thambema golanachum Harrison, 1987 and T. fiatum Harrison, 1987 but can be distin− guished from both species by the shape of male pleopod 1, the number of claws on pereopods 2–7 and the setation of pereopod 1 and 2 carpus, respectively. A key to all known genera and species in the family Thambematidae is also provided.
Subtropical Cyclones over the Southwestern South Atlantic: Climatological Aspects and Case Study

AbstractHurricane Catarina (2004) and subtropical storm Anita (2010) called attention to the development of subtropical cyclones (SCs) over the South Atlantic basin. Besides strong and organized storms, a large number of weaker, shallower cyclones with both extratropical and tropical characteristics form in the region, impacting the South American coast. The main focus of this study is to simulate a climatology of subtropical cyclones and their synoptic pattern over the South Atlantic, proposing a broader definition of these systems. In addition, a case study is presented to discuss the main characteristics of one weak SC. The Interim ECMWF Re-Analysis (ERA-Interim) and NCEP–NCAR reanalysis are used to construct the 33-yr (1979–2011) climatology, and a comparison between them is established. Both reanalyses show good agreement in the SCs’ intensity, geographical distribution, and seasonal variability, but the interannual variability is poorly correlated. Anomaly composites for austral summer show that sub.
Analysis of the Implementation of Laboratory Activities in High School Physics Learning from the Perceptions of Teachers and Principals

The laboratory is the main means of learning contextual physics. The results of observations in high schools of Padang Pariaman Regency, West Sumatra, showed that the implementation of laboratory activities in learning physics was still low. An analysis was conducted to highlight the implementation of these laboratory activities in high school physics learning in terms of teachers’ and principals’ perceptions. Aspects that can be disclosed are a) the implementation of laboratory activities in terms of; availability of infrastructure and perceptions of teachers and school principals on laboratory activities, and b) the relationship between teachers’ and principals’ perceptions of laboratory activities in physical education. Sampling was done using the Cluster Random Sampling technique. The data obtained were described using the percent technique. The results of data analysis and processing concluded that a) in terms of the availability of facilities and infrastructure for the implementation of laboratory activities, the average was in the very low category (17.86%), b) The perception of teachers and principals on laboratory activities in physical learning was on average the same for the lower criteria (43.00%) and 45.20%); and c) data on the relationship between the perceptions of teachers and principals on laboratory activities is in a very strong (0.816) and strong (0.788) relationship with their respective contributions of 66.60% and 62.10%. In general, this analysis concludes that a very low percentage The implementation of laboratory activities is largely influenced by the low perception of teachers and principals’ perceptions of the role of laboratory activities in learning physics.

Methane emission from flooded forest in central Africa

In this report we give results of methane flux measurement in the flooded forest zone of the Congo River basin in central Africa. Methane fluxes are measured by the static chamber method above three types of soils characterized by various water contents. High methane emission is recorded on flooded soils (4.59 × 1012 molecules/cm2/s) while methane uptake occurs in dry soil (−8.38 × 1010 molecules/cm2/s). Methane flux is also derived from variations of surface concentrations of methane related to the variations of air stability and from vertical profiles in the lower troposphere. The four methods used to determine the average methane emission from this wetland type yield compatible values. The average yearly flux is estimated at 2 to 4 × 1012 molecules/cm2/s or 45 to 90 mg/m2/d The total wetland area being about 105 km2, global methane emission from the flooded forest zone of the Congo River basin would represent 1.6 to 3.2 Tg (CH4) per year.
Impact of materials on performance of Vine Robot

Vine Robots are soft continuum robots designed with low-cost fabrication and for the navigation of difficult environments. Due to their movement patterns resembling those of natural vines, these robots also known as “everting vine robots” grow by pressure-driven eversion. This paper presents the impact of different materials on the performance of Vine Robot. Three of the most easily accessible materials namely Transparent LDPE (125 Microns), Black LDPE (150 Microns) and Tarpaulin HDPE (250 Microns) were acquired and utilized in fabricating the body of Vine Robot. Under the application of these materials, difference in various properties of the robot were studied. By systematic study, the suitability of one material over the other was determined in specific environmental scenarios.
Effects of Velocity on the Transport of Two Bacteria Through Saturated Sand

Transport of the bacteria Klebsiella oxytoca and Burkholderia cepacia G4PR1 (G4PR1) was investigated in column experiments conducted under conditions that allowed us to quantify sorption under a range of ground water velocities. Column experiments (33 mm I.D. × 114 mm long columns) were conducted at four linear water velocities (0.5 to 14 cm.hr−1) through a medium to coarse grained silica sand. The peak C/Co concentrations for both bacteria were attenuated with respect to a conservative tracer (Cl−), and well‐defined tailing was observed. Breakthroughs of both bacteria were influenced by the water velocity. In the case of G4PR1, the attenuation of the peak C/Co concentrations increased as the velocity decreased while the peak C/Co concentrations for K. oxytoca were similar at velocities between 3 and 13 cmhr−1 but decreased at the lowest velocity tested (0.6 cm‐hr−1). The tailing reached constant C/Co values of between 2 × 10−3 and 5 × 10−3, and between 2 × 10−5 and 5 × 10−5 for K. oxytoca and G4PR1 after 2t0. A one‐dimensional mathematical model for advective‐dispersive transport that accounts for irreversible (kirr) and reversible (kf and kr) sorption was used to quantify the sorption process. Both irreversible and reversible sorption was required to obtain good fits to the measured K. oxytoca data. Results of this modeling suggested that kirr and kr are independent of velocity and an empirical relationship was developed relating kf to velocity. For G4PR1, the best fits were obtained using only reversible sorption. Results of the modeling suggested that kf was independent of velocity at all velocities tested and kr was independent of velocity at velocities between 3 and 13 cmhr−1. At the lowest velocity investigated (0.5 cmhr−1), the kf value decreased considerably. This study showed that sorption characteristics are bacteria specific, and are likely related to surface chemistry because G4PR1 is more hydrophobic than K. oxytoca. The study also showed that in order for bacterial transport experiments to be directly applicable to the subsurface, they should be conducted at velocities similar to those observed in the subsurface, or the relationship between the sorption parameter(s) and velocity should be known.
An Experimental Investigation of Surface Quality in Single Point Incremental Forming of Cu-Al Composite Sheets

Single-point incremental forming (SPIF) has been developed as a customized substitute of traditional sheet metal forming techniques. SPIF is a great method for rapidly prototyping sheet metal objects, although it faces challenges in achieving surface quality and thickness distribution. In this investigation, sheets of Cu-Al bimetallic composite were formed utilizing a hemispherical-headed tool with a variety of step depths, spindle speeds, forming speeds, layer arrangements, and lubrication types. Surface roughness and minimum thickness were evaluated as response parameters in relation to the significance of process variables. The best surface quality was attained with 0.4 mm step depth, 750 mm/min forming speed, and 1500 rpm spindle speed with liquid lubrication support for both types of layer arrangements. Layer arrangement and lubricant type were the decisive factors for the minimum thickness response parameters.
On the distributions of long‐lived tracers and chlorine species in the middle atmosphere

A numerical model employing the residual Eulerian formulation and small eddy diffusivity coefficients is used to calculate the distributions of chemical tracers and chlorine species. The predicted densities of nitrous oxide, methane, and chlorocarbons are shown to be in good agreement with available observations and to exhibit strong latitude gradients. Computed spatial variations in methane produce large variations in the HCl and ClO densities. In particular, a pronounced local minimum in HCl is obtained near 40 km for certain latitudes and seasons, with a corresponding maximum in ClO, primarily as a result of transport of atmospheric methane. It is suggested that spatial and short-term temporal variability in methane has potentially important consequences for the HCl and ClO distributions in the atmosphere, and their variability, and for the chlorine-catalyzed destruction of stratospheric ozone.
FLUVIAL GEOMORPHOLOGICAL METHODOLOGY FOR NATURAL STABLE CHANNEL DESIGN 1

A fluvial geomorphological methodology for designing natural stable channels is being widely applied for river restoration. It is an analogue procedure, as the W/d ratio and sinuosity from a reference reach are scaled to determine the restoration design. The choice of reference reach is crucial and published criteria specify that it should be stable, correspond to the stream type at the restoration site, have the same valley type, and be from the same hydrophysiographic region. For stable, meandering gravel cobble bed rivers flowing through alluvial flood plains (C3 and C4 stream types), UK regime equations are used to evaluate the procedure. Successful design requires particular combinations of the ratios of bankfull discharge, bed material size and load, valley slope, and bank vegetation category between the reference and restoration sites. These critical ratios, which are confirmed by U.S. field data, provide guidelines for selecting a suitable reference reach for C3‐C4 stream types. They also indicate that the reference reach can be in any valley type or hydrophysiographic region. The geomorphological procedure will apply to all stable stream types, provided the reference reach is correctly identified. Specific guidelines for each stream type await the development of additional regime equations.
