Top Fifty Highly Cited Publications on the Internet of Things

The present study aimed at analyzing the publication pattern of highly cited research publications of Internet of Things. Web of Science citation database was used to extract data for the study. The top fifty highly cited publications were considered as the sample of this study. The data were analyzed based on publication year, document type, source title, time cited, usage count, authorship pattern, collaborative coefficient, research collaboration, and research areas. The findings revealed that majority of the publications were research articles and most of them were published in IEEE journals. Research articles written by multiple authors were more prominent than single-author publications. Researchers from USA and China preferred collaborative research and researchers from Italy preferred non-international collaborative research. The researchers from developed western countries are highly engaging with research in Internet of Things. The most popular research areas under Internet of Things are computer science and telecommunication.
The Relationship of Social Presence and Interaction in Online Classes

The purpose of this research was to study social presence in the online learning environment. Dimensions of social presence were examined using quantitative and qualitative methods. Three dimensions of social presence-social context, online communication, and interactivity-emerged as important elements in establishing a sense of community among online learners. The privacy factor was also an important element in the level of comfort for students online. An increase in the level of online interaction occurs with an improved level of social presence. This can be fostered by considering characteristics of the learners, by selecting the appropriate computer-mediated communication medium, and by applying appropriate instructional elements to course design.
Biopsychosocial factors in drives for muscularity and muscle dysmorphia among personal trainers

Abstract Muscle dysmorphia (MD) is a type of body dysmorphic disorder related to body image disturbances associated with musculature and leanness. This study surveyed the presence of MD and drive for muscularity (DFM) in both male and female personal trainers (n = 1039, Mage = 35.10, SD = .38) using a biopsychosocial foundation. Prevalence rates for MD and a DFM in the current sample were 23 and 28%, respectively. Kendall’s tau-b revealed that general appearance concerns, muscle concerns, and somatic features were positively related to both MD and a DFM. A DFM and MD were significantly, positively correlated with internalization of thin ideals, muscular/athletic ideals, family and peer pressures, but not media pressures. All psychopathologic variables (depression, anxiety, hostility, somatization, interpersonal sensitivity, obsessive-compulsive) were significantly and positively related to MD and DFM. Men and women who displayed high MD and DFM behaviors did so with little disparity, suggesting that these behaviors may be less gender-specific for personal trainers. Physique concealment was the only subscale of the MDI to depict a significantly positive relationship with every variable across each biopsychosocial dimension except for race, suggesting that this behavior may be more central to MD than putatively believed. This study furthers the extant knowledge of MD and a DFM by exploring an under-researched population and providing data structured in a unique biopsychosocial framework that serves as a viable basis for continued research with this and other populations.
Morphological, mechanical and biological assessment of PCL/pristine graphene scaffolds for bone regeneration

Scaffolds are physical substrates for cell attachment, proliferation, and differentiation, ultimately leading to the regeneration of tissues. They must be designed according to specific biomechanical requirements such as mechanical properties, surface characteristics, biodegradability, biocompatibility, and porosity. The optimal design of a scaffold for a specific tissue strongly depends on both materials and manufacturing processes. Polymeric scaffolds reinforced with electroactive particles could play a key role in tissue engineering by modulating cell proliferation and differentia-tion. This paper investigates the use of an extrusion additive manufacturing system to produce PCL/pristine graphene scaffolds for bone tissue applications. PCL/pristine graphene blends were prepared using a melt blending process. Scaffolds with regular and reproducible architecture were produced with different concentrations of pristine graphene. Scaffolds were evaluated from morphological, mechanical, and biological view. The results suggest that the addition of pristine graphene improves the mechanical performance of the scaffolds, reduces the hydrophobicity, and improves cell viability and proliferation.
Review of Methods to Calculate Congestion Cost Allocation in Deregulated Electricity Market

With maturing deregulated environment for electricity market, cost of transmission congestion becomes a major issue for power system operation. Uniform Marginal Price and Locational Marginal Price (LMP) are the two practical pricing schemes on energy pricing and congestion cost allocation, which are based on different mechanisms. In this paper, these two pricing schemes are introduced in detail respectively. Also, the modified IEEE-14-bus system is used as a test system to calculate the allocated congestion cost by using these two pricing schemes.
EXPRESSION OF CYPscc AND 3B-HSD mRNA IN BITCH OVARY AFTER LONG-TERM EXPOSURE TO ZEARALENONE

In the presented study, sexually immature beagle b itches were exposed per os to 50 or 75 µg/kg b.w. of zearalenone (ZEA) for 42 d, and real-time qPCR assay was performed to i nvestigate a possible effect of the treatment on CYP scc and 3 β-HSD mRNA expression in canine ovary. While the exposure of b itches to ZEA at a lower dose (50 µg/kg b.w.; 100% NOAEL) did not cause distinct effect on the expression of examined genes , the treatment with the higher dose (75 µg/kg b.w.; 150% NOAEL) resulted in over 5-fold increase in 3 β-HSD mRNA level (P<0.05). The results suggest that the appearance of ZEA in bitches ovaries may trigge r the accumulation of 3 β-HSD in a way similar to that of pregnenolone. Furt her, more detailed experiments need to be performed in order to assess whether ZEA and its major metabolit es, α- and β-zearalenol, are involved in transcriptional regula tion of the key steroidogenic enzymes.
Determining the relative position of a device in a wireless network with minimal effort

Unlike wired lighting systems, wirelessly controlled luminaires have no fixed connections between lights and switches. The position of a luminaire is an important attribute for either lighting application or other applications requiring position information in a building. Normally during the commissioning process, a commissioning person is required to manually locate the devices and assign their IDs on the floorplan. This master thesis proposes algorithms to perform an almost automatic device localization, in which a relative relationship matrix is generated from Received Signal Strength Indication (RSSI) and the lighting layout with devices’ IDs is determined by matching the relative relationship matrix with floorplan. The automatic device localization will shorten the commissioning time considerably. The main shortcoming of using RSSI is its instability and the interference susceptibleness noticed in real environments. Experiments are carried out to explore the characteristics of fundamental factors contributing to RSSI variability. Methods and assumptions are introduced to come up with a reliable relative relationship matrix between nodes. Two matching algorithms are introduced to match the devices’ IDs with the positions in the floorplan to formulate the final layout and both of them achieve high accuracy.

Weighing Uranus’ Moon Cressida with the η Ring

The η ring is one of the narrow rings of Uranus, consisting of a dense core that is 1–2 km wide and a diffuse outer sheet spanning about 40 km. Its dense core lies just exterior to the 3:2 Inner Lindblad Resonance of the small moon Cressida. We fit the η ring radius residuals and longitudes from a complete set of both ground-based and Voyager stellar and radio occultations of the Uranian rings spanning 1977–2002. We find variations in the radial position of the η ring that are likely generated by this resonance, and take the form of a 3-lobed structure rotating at an angular rate equal to the mean motion of the moon Cressida. The amplitude of these radial oscillations is 0.667 ± 0.113 km, which is consistent with the expected shape due to the perturbations from Cressida. The magnitude of these variations provides the first measurement of the mass and density of the moon Cressida ( kg and g cm−3) or, indeed, any of Uranus’ small inner moons. A better grasp of inner Uranian satellite masses will provide another clue to the composition, dynamical stability, and history of Uranus’ tightly packed system of small moons.

Experimental Sequential Designs for Logistic Regression Models

When the usual hypotheses of normality and constant variance do not hold (e.g. in binomial or Bernoulli processes), the problem of choosing appropriate designs creates problems to researches when pursuing a sequential exploration of process. This paper is based on De Zan (2006), where the author proposes two criteria to evaluate design strategies, that take the amount of information as the main evaluation tool. One into account the information of the fitted model, and the other explores the information that is contained on the approximation of a set of the best conditions of factors found on a fitted model. An example of how these strategies work is also given through a simulation using R software.
How Well is the Tropical Africa Prepared for Future Physiologic Stress? The Nigerian Example

The huge literature gap in the knowledge of physiologic climatology on tropical Africa indicates poor awareness to the issue of physiologic stress in the region. This study examined the variability in the physiologic comfort over Nigeria using both annual and hourly patterns of unitary (temperature and relative humidity) and integrative indices (effective temperature, temperature-humidity and relative strain indices), as well as assessing the perceptions of a randomly selected Nigerians in 18 tertiary institutions across the country. Results indicated thermal stress in Nigeria, and showed that both heat and cold stress varied temporally (annually and hourly) and spatially (1200-1500 Local Standard Time, LST as the most thermally uncomfortable period of the day, and ≤ 0900 and around 2100 LST were more comfortable). Perception of the comfortable climate exhibits variation based on the latitudinal location of the respondents but the coping strategies vary with the wealth of individuals. The study indicated that whilst many parts of Nigeria could be vulnerable to physiologic stress, indigenous and modern know-how to cope with future physiologic stress is largely unknown. The study therefore recommends significant improvement in climate-oriented policies, especially in the areas of healthcare and infrastructure.
An Empirical Approach for Medical DiagnosisUsing Image Segmentation and ShapeAnalysis

An image is an array, or a matrix, of square pixels (picture elements) arranged in columns and rows. The goal of image segmentation is to cluster pixels into salient image regions, i.e., regions corresponding to individual surfaces, objects, or natural parts of objects. The segmentation could be used for object recognition, occlusion boundary estimation within motion or stereo systems, image compression, image editing, or image database look-up. Image processing plays a key role in computer aided diagnosis and medical practice. Shape analysis plays an important role in feature extraction and analysis. In this paper a technique is proposed to detect anaemic erythrocytes using image segmentation and shape parameters.
A detector for filtering gray spectra from weak fusion – evaporation reactions out of strong background and for Doppler correction : The recoil filter detector , RFD

A detector has been designed and built to assist in-beam g-ray spectroscopy with fusion–evaporation reactions. It measures with high efficiency the evaporation residues that recoil out of a thin target into the angular interval from 1.81 to 9.01 at an adjustable distance of 1000–1350mm from a target, in coincidence with g-rays detected in a Ge-detector array. This permits filtering of such g-rays out of a much stronger background of other reaction products and scattered beam. Evaporation residues are identified by their time-of-flight and the pulse height using a pulsed beam. The velocity vector of the g-emitting recoil is also measured in the event-by-event mode, facilitating to correct the registered g-ray energy for the Doppler shift, with the resulting significant improvement of the energy resolution. The heavy-ion detection scheme uses emission of secondary electrons caused by the recoiling ions when hitting a thin foil. These electrons are then electrostatically accelerated and focused onto a small scintillator that measures the summed electron energy, which is proportional to the number of electrons. The detector is able to operate at high frequency of the order of 1MHz and detect very heavy nuclei with as low kinetic energy as 5MeV. The paper describes the properties of the detector and gives examples of measurements with the OSIRIS, GAREL+ and EUROBALL IV g-ray spectrometers. The usefulness of the technique for spectroscopic investigations of nuclei with a continuous beam is also discussed. r 2007 Elsevier B.V. All rights reserved. PACS: 29.30. h; 29.30. Kv; 29.40. Gx
PRINTED MEANDER LINE MIMO ANTENNA INTEGRATED WITH AIR GAP, DGS AND RIS: A LOW MUTUAL COUPLING DESIGN FOR LTE APPLICATIONS

Multiple-input and multiple-output (MIMO) is currently regarded as key technology for long term evolution (LTE) but a critical effect is mutual coupling (S21) due to space constraint in miniaturized design. A compact-size antenna with low mutual coupling would be an ideal choice for better system performance. This paper describes the design of a small-size (48×48 mm2) MIMO antenna system with low mutual coupling for LTE 800 MHz applications. The antenna system comprises of two FR-4 substrate layers; one printed with two meander line antennas (MLAs), the other printed with reactive impedance surface (RIS) and defected ground structure (DGS). The properties of the antenna like S-Parameters, excited surface current distribution, far-field radiation pattern and diversity performance characteristics were studied. The results indicated that MLAs rendered compactness to the system. Introduction of air gap (AG) between the two substrates, DGS and periodic square patches of RIS resulted in 452 MHz bandwidth and mutual coupling of −41.18 dB between antenna elements. The performance of the proposed design compared with other reported geometry has been demonstrated. Parameters including bandwidth, ratio of antenna area/improvement in S21, antenna efficiency and the envelope correlation coefficient were compared. Considering the results, the present system appears to be comparatively more efficient.
Atmospheric and Sea-Ice Conditions in the Northwest Atlantic During the Decade, 1991-2000

Atmospheric and sea ice conditions within the Northwest Atlantic during the decade 1991–2000 are described. The NAO index in the 1990s was the highest in the past 11 decades and there has been a general increase from the minimum of the 1960s. The high NAO in the 1990s was accompanied by an increase in southwesterly winds in the Labrador Sea region. With the exception of Nuuk, mean decadal air temperatures were above their long-term means at selected sites throughout the NAFO area, including record high decadal means in the Gulf of St. Lawrence and at Cape Hatteras. Air temperatures have generally been increasing since the 1960s from the Scotian Shelf northward. Sea-ice conditions off the Labrador and northern Newfoundland coast, in the Gulf of St. Lawrence and the Scotian Shelf indicate the least amount of ice in the 1960s. From Labrador to the Gulf of St. Lawrence there was little difference in ice severity between the 1970s, 1980s and 1990s; however, on the Scotian Shelf the ice area was less during the 1990s compared to the previous two decades. The decadal mean of the number of icebergs drifting southeastward along the Labrador and Newfoundland shelves was at a maximum during the 1990s. There has been large intra-decadal variability in all climate indices examined. The early years of the 1990s were characterized by high NAO indices, strong northwesterly winds, cold air temperatures from the Labrador Sea to the Gulf of Maine, and extensive ice cover. In 1996, the NAO index experienced its largest annual decline in the over 100-year record. During the remaining years of the 1990s decade, the NAO rose achieving values that even exceeded those of the early years of the 1990s. Of significance during the latter half of the decade was the eastward shift in the center of the atmospheric low-pressure system over the Northwest Atlantic. This shift contributed to weaker northwesterly winds, warmer temperatures in the Labrador Sea to the Gulf of Maine, and a reduction in sea-ice.
Forward hadron production at the LHC

Observations of ultra high energy cosmic rays by extensive air showers rely on correct modeling of hadronic interaction in the forward region at very high energy. Recent new data from the LHC, especially for forward particle production, are important for a precise understanding of air shower development. In this article recent forward production data from p-p, p-Pb, and Pb-Pb collisions at LHC are reviewed.
Case of Enterprise Architecture in Manufacturing Firm

— The small and medium enterprises (SME’s) have a low level of survival and are facing serious problems like access to financing, weak management capacity, poor information about market opportunities, limited information about access to innovation and research funds, new technologies and methods of work organization, the integration of its key processes into information and communication technologies (ICT’s). The methodology of Enterprise Architecture (EA) can provide a model of integration supported with strategic planning, integrated by partial architectures like business, data, applications and technology. In this study case, we are providing information that was collected from different sources of a medium manufacturing firm to design and implement an EA. As a result we get to the identification of strategic changes supported by the methodology, the assessment of option for change, and a change plan for the adoption of the methodology in their processes; those processes must improve their competitiveness and productivity.
Crowding under diverse distance criteria for niche formation in multimodal optimization

Niche formation allows evolutionary algorithms to be used when the location and maintenance of multiple solutions appertaining to diverse areas of the phenotypic space is required. Consequently the application field can be extended to multiobjective optimization, simulation of complex systems and multimodal function optimization. In this later case a conventional evolutionary algorithm tends to group the final population around the fittest individual. Thus, other areas of interest in the search process are lost. Niching methods permits the maintenance of solutions located around these areas of interest. This contribution briefly describe problems preventing niche formation in conventional genetic algorithms, a crowding method for niche formation and analysis of results when optimizing two multimodal functions.

An enhanced algorithm for removal of noise in CT scan image and 3D abdomen color video sequence through trimmed based filter

In this paper, a new Trimmed Median (TM) filter to remove high density fixed impulse noise in CT (computerized tomography) scan images and abdomen color video sequence is proposed. Initially, a 3 × 3 sliding window is applied on each pixel in the noisy image and color video sequence frame. The minimum and maximum intensity values are trimmed and the noisy pixels are detected based on the predefined threshold value. In the filtering stage, the noisy pixels are replaced by median value of uncorrupted pixels in the trimmed array. At very high noise density, if all the pixels in the sliding window are corrupted then the proposed algorithm replaces noisy pixel by midpoint of recently processed pixels. The experimental results for noisy lung CT scan image show that the performance of proposed algorithm is superior to existing algorithms in terms of visual quality and edge preservation, even at noise level as high as 95%.
Patterns for distributed machine control system data sharing

In this paper we will present three patterns for sharing sensory data and other information in distributed machine control systems. A distributed machine control system is a software entity that is specifically designed to control a certain hardware system. This special hardware is a part of a work machine, which can be a forest harvester, a drilling machine, elevator system etc. or some process automation system. Some of the key attributes of such software systems are their close relation to the hardware, strict real-time requirements, functional safety, fault tolerance, high availability and long life cycle. Data sharing is essential part of achieving distribution as collaboration between different parts of the system requires data exchange.
