Systematic Mapping Study on RFID Technology

Radio Frequency Identification (RFID) is a technology that not only serves to identify objects but also communicates other information, allowing the real-time monitoring of objects at each step in a mobile object network and the reporting of information on their current status. RFID has become one of the most promising research areas and has attracted increasing attention. This interest sparks a huge amount of literature in the field of RFID. However, the research has been conducted from different perspectives and, as a result, has led to a growing body of knowledge dispersed in different fields. To fill this gap, we carried out a systematic mapping study (SMS) based on a well-established research methodology from the medical and software engineering scientific communities, which aims to study and identify the approaches used, quantity and quality of publications, types of research, and publication trends that shaped the field of RFID research over the past two decades. Its results were based on 219 studies, rigorously selected from among 4294 studies identified in the IEEE Xplore, Scopus, and Web of Science digital libraries and classified according to the research type facet, research area facet, citation facet, and application domain facet. We synthesized and interpreted the results of this SMS to devise future research directions in the RFID domain. This breadth-first SMS provides a solid, comprehensive, and reproducible picture of state-of-the-art RFID technology; the obtained results may have implications for practitioners willing to understand and adopt RFID, including researchers, journal editors, reviewers, and universities. The results obtained revealed that (1) there is a considerable and continuous rise of RFID research activities around different parts of the globe, including in the USA and China, and other English-speaking developed countries, such as Australia, Canada, and the U.K., have a significant influence on this growth; (2) with the technological progress of RFID hardware components and increasingly demanding application domains, RFID technology brings opportunities in some new areas, such as “IoT applications”, “Complex Environments”, and “Industry 4.0”; (3) despite the high number of studies carried out in the field of RFID, especially in the hardware design and performances subfield, a limited number of works have detailed or focused on the “middleware” component of RFID systems, indicating that RFID data processing and management remain an open research issue; and (4) RFID domain challenges, gaps, and feasible future recommendations were highlighted in this study.

Structure and kinetics of three-dimensional defects on the [formula omitted] twin boundary in magnesium: Atomistic and phase-field simulations

Twinning is an important plastic deformation mechanism in Mg. While computational and experimental efforts have studied the two-dimensional equilibrium structure of boundaries and facets that surround twin domains, little consideration has been given to three-dimensional nonequilibrium structures. Furthermore, the relationship between the structure of nonequilibrium facets and the kinetics of twinning is also not well understood. Thus, the objective of this work is to characterize the structure of three-dimensional defects on the {101¯2} twin boundary and to study the kinetics associated with motion of the facets that bound these three-dimensional defects. Atomistic simulations show that the three-dimensional defects are bounded by nonequilibrium facets with prismatic/basal and twist pyramidal/pyramidal interfaces. The three-dimensional defects are surrounded on the {101¯2} twin boundary by disconnection loops. The kinetics of the twin domain facets at finite temperature are analyzed by both molecular dynamics and a newly proposed anisotropic phase-field model. The latter allows the deconvolution of the competing role of interface energy, mobility and internal stress state. Molecular dynamics simulations show that inclined facets control the annihilation process; this behavior is captured in the phase-field model using mobility for the coherent twin boundary that is significantly lower than that of crater inclined facets. Furthermore, molecular dynamics simulation results are best matched via the introduction of facet orientation dependent excess energies.

Facets in LISTA

Knowledge Organization Systems (KOSs) use arrays of related concepts to capture the ontological content of a domain; hierarchical structures are typical of such systems. Some KOSs also employ sets of cross- conceptual descriptors that express different dimensions within a domain—facets. The recent increase in the prominence of facets and faceted systems has had major impact on the intension of the KO domain and this is visible in the domain’s literature. An interesting question is how the discourse surrounding facets in KO and in related domains such as information science might be described. The present paper reports one case study in an ongoing research project to investigate the discourse of facets in KO. In this particular case, the formal current research literature represented by inclusion in the “Library, Information Science and Technology Abstracts, Full Text” (LISTA) database is analyzed to discover aspects of the research front and its ongoing discourse concerning facets. A dataset of 1682 citations was analyzed. Results show thinking concerning information retrieval and the semantic web resides alongside implementation of faceted searching and the growth of faceted thesauri. Faceted classification remains important to the discourse, but the use of facet analysis is linked directly to applied aspects of information science.

Numerical Modeling of a Simplified Ground Heat Exchanger Coupled with Sandbox

The ground heat exchanger (GHE) system is an energy-efficient application employing the geothermal energy in residential and commercial buildings. Compared with field tests or laboratory measurements, computational fluid dynamics and heat transfer offers a cost-effective approach to give accurate prediction on thermal performance assessment of the GHE system. In this study, the effects of different boundary configurations were numerically investigated based on a referred laboratory GHE experiment. First, both recorded input water temperature profile and the given heat load were used as heat input for numerical simulations, and all facets of the ground domain were set as adiabatic condition. Through comparing the numerically predicted output water temperature profile with the experimental recorded one, the first approach using the recorded input water temperature profile as heat input gave a close prediction with the experimental data, while the numerical results based on the second approach using the given heat load showed a considerable discrepancy compared with experimental data. This comparison discrepancy can be attributed to the adiabatic assumption for the ground domain facets through heat balance analysis, and can be addressed by introducing a dynamic thermal boundary configuration for side- and end-walls. This study demonstratedthe significance of boundary conditions consideration and provided a solution by utilizing dynamic thermal boundary treatments compared with the adiabatic assumption. The numerical modeling methods can contribute towards improved GHE numerical simulations based on finite ground domains.

Model Based Self‐Learning System Engineering Approach

AbstractSystem requirements engineering is relatively matured discipline with many trusted and dependable methods and techniques that fairly helps in identifying, analyzing, specifying, managing, verifying, and validating the system requirements. Yet the major challenge perceived in system engineering and development of software that is persisting over many years and pervasive across all domains is the requirements development, analysis, management, and validation. Still there are projects attributing to the defects in system requirements as the prime cause of its failure. Is a radical change to the current approach and techniques is essential or is it that we are not able to put the best practices designed into good use or both? Is there something else amiss that is not proportioned into these methods or tools and needs to be accounted into it? Several approaches attempt to increase the standardized portion by making it more objective and diminish the subjective substance. Towards this objective numerous tools and models were evolved over past several years aiming to standardize the requirements acquisition practice through various instruments like a questionnaire, design of use‐cases or models that consumes inputs from every stakeholder and use a standard template that brings in objectivity eliminating the ambiguity. These models are as intelligent as per the capabilities of the templates or the outlines created and matures per their exposure levels to the scenarios. They concentrates more on the methodology, patterns or blueprint to capture different characteristics and properties associated to the product in the requirements and the domain perspective is less deliberated. Domain viewpoint is of utmost importance to ensure the functioning of the product in the required environment and ambiance with required performance criteria that is suitable to the product. The “Domain Driven Design” is yet another approach to capture the requirements, develop and maintain it. A study of these three different approaches from the existing literature is done in this paper bringing out their prominent features, advantages and shortcomings. The proposed model delves deep into augment the domain facets of the products to ensure the definition of requirements are comprehensive and all‐inclusive to facilitate the flawless development and complete testing by reducing the ambiguity and enhancing the clarity. It also targets to produce all relevant artifacts like use cases, test scenarios, documentation etcetera. Collation and embedding of the precious and adept data from the experienced system engineers is one of the best features of the suggested model.

Phase Separation on Bicontinuous Cubic Membranes: Symmetry Breaking, Reentrant, and Domain Faceting.

We study the phase separation of binary lipid mixtures that form bicontinuous cubic phases. The competition between the nonuniform Gaussian membrane curvature and line tension leads to a very rich phase diagram, where we observe symmetry breaking of the membrane morphologies and reentrant phenomena due to the formation of bridges between segregated domains. Upon increasing the line tension contribution, we also find faceting of lipid domains that we explain using a simple argument based on the symmetry of the underlying surface and topology.

High-Symmetry Polarization Domains in Low-Symmetry Ferroelectrics

We present experimental evidence for polygonal domain faceting in the ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) films with the lower orthorhombic crystallographic symmetry. It is proposed that this effect can arise from purely electrostatic depolarizing forces. We show that, in contrast to magnetic bubble shape domains, where such type of deformation instability has a predominantly elliptical character, the emergence of more symmetrical circular harmonics is favored in ferroelectrics with high dielectric constants.

The percieved roles of academic libraries in present and in future: the case of Faculty of art’s libraries

AbstractThroughout history libraries have had many different roles. They served as educational centres, manuscript transcriptors and collectors, places for study, places offering services, even museums and entertainment facilities, etc. Their quality depends on a number of different factors, e.g. quality of staff, and of services, as well as on environmental characteristics. The current development in the information and communication technology has an important impact on libraries functions and therefore demands their permanent adjustment. In this study the authors tried to find out how 171 students and librarians from the Faculty of Arts perceive the current and future roles of academic libraries. Following this, the questionnaire was prepared on the basis of the following domain facets: time frame, services, communication type and type of material. As expected in the partitions of the three dimensional (Smallest Space Analysis) space three facets with ordered elements appeared (two axial: time frame and material, and one modular: communication type) and one unordered with the polar role: services. With the exception of the service facet, all the other facets clearly revealed themselves.

Superconducting β-ZrNClx probed by scanning-tunnelling and break-junction spectroscopy

Superconducting layered compound β-ZrNClx (x=0.7) with the critical temperature Tc=13–14K was investigated by means of scanning tunnelling microscopy/spectroscopy. The single-crystal domain facet of ∼100μm2 in the c-axis-oriented polycrystal was used as a probing surface. The STM image at 4.9K shows triangular atomic lattice spots with the period of ∼0.36nm, which agrees with the X-ray diffraction measurements. The STS measurements of the local conductance, dI/dV, exhibit broadened gap structures with a substantial distribution of the gap-edge values. Most frequently observed peak-to-peak value of ∼20mV is remarkably similar to the superconducting gap edge of the isostructural β-HfNClx with Tc=24K. Temperature, T, dependence of the dI/dV shows that the gap structure disappears above Tc∼13K. Fitting of the dI/dV curve by the broadened BCS density of states leads to the superconducting gap of 2Δ(4.9K)=11–13meV. This is in accordance with our former break-junction data confirming the intrinsic character of the previously obtained extremely large gap to Tc ratio 2Δ(0)/kBTc≈10 (kB is the Boltzmann constant), thereby pointing to the unusual superconducting properties of this compound.

Domain faceting in an in-plane magnetic reorientation transition

The microscopic structure of the $90\ifmmode^\circ\else\textdegree\fi{}$ in-plane magnetic reorientation transition in Fe(110) films is examined using photoemission x-ray microscopy. At the nanoscale, sharp magnetic boundaries are detected. They are indicative of a first-order transition and are consistent with Fe magnetic anisotropy constants. At the micron scale, the magnetic boundary breaks up into triangular patterns whose characteristic angular dependence is revealed by experiments on conical microwedges. This effect, fully accounted by micromagnetic simulations, opens the possibility to control the sharpness of the transition at the microscopic scale.

Internal Consistencies and Structural Analysis of the MMPI-2 PSY-5 Facet Subscales in Chinese Population

Using the normative data set of the Minnesota Multiphasic Personality Inventory-2 of the People’s Republic of China, this study examined the psychometric properties of the Personality Psychopathology Five facet subscales recently developed by Arnau et al. (2005). The internal consistency reliability, convergent and discriminant validity of the Psy-5 were found to be unsatisfactory. Results of confirmatory factor analysis (CFA) indicated that both item-to-facet factor structure (except the PSYC domain facets subscales) and facet-to-domain factor structure fit the data poorly. These findings suggested that the PSY-5 facet subscales may not be reliable and valid in population independent of those used to derive them. Thus, the utility of these facet subscales in clinical and research settings is premature at least for Chinese people at the present time.

The Validity of Cloninger's Psychobiological Model Versus the Five‐Factor Model to Predict DSM‐IV Personality Disorders in a Heterogeneous Psychiatric Sample: Domain Facet and Residualized Facet Descriptions

The validity of Cloninger's psychobiological model and the Five-Factor Model of personality to predict DSM-IV personality disorders was examined in a psychiatric in-patient sample of 130 individuals. Patients completed Dutch authorized versions of the TCI (Cloninger, Svrakic, & Przybeck, 1993) and the NEO PI-R (Costa & McCrae, 1992) and were also administered the ADP-IV (Schotte & De Doncker, 1994), a Dutch self-report questionnaire to assess Axis-II disorders. No personality-descriptive model proved to be superior in explaining personality disorder symptoms at the higher-order level: the TCI dimensions better explained the Obsessive-Compulsive and the Narcissistic disorders, whereas the FFM accounted for more variance of the Avoidant disorder. However, differences were apparent at the lower-order level with the NEO facets out performing the TCI subscales for six to four personality disorders. FFM facet-level predictions of Widiger, Trull, Clarkin, Sanderson, and Costa (2002) were partially confirmed, with substantially better results using residualized facet scores. A set of TCI subscale personality disorder relationships is suggested.

Clinical spectrum of episodic ataxia type 2.

The authors searched for mutations in CACNA1A in patients with episodic ataxia and describe the clinical spectrum in genetically defined patients. Eighteen families and nine sporadic cases of episodic ataxia were evaluated for mutations in CACNA1A. The families were first genotyped to check for linkage to the chromosome 19p locus of CACNA1A. In families consistent with linkage and in the sporadic cases, the authors screened for polymorphisms in CACNA1A using single-strand conformational polymorphism and denaturing high performance liquid chromatography followed by direct sequencing to identify specific nucleotide changes. Of the 18 families, 11 were linked to 19p and mutations were found in 9. Mutations were detected in four of the nine sporadic cases. Overall, five nonsense mutations, four missense mutations, two deletions, one insertion, and one donor splice mutation were identified. All but two of the 64 genetically defined patients reported episodes of ataxia (two members of one family only had progressive ataxia). All but one had onset before age 20 and all but four had interictal nystagmus. Migraine headaches occurred in more than half, and about two thirds reported a good response to treatment with acetazolamide. Vertigo and weakness accompanied the ataxia in more than half of the genetically defined patients. One family had multiple members with epilepsy. A wide range of mutations in CACNA1A were associated with episodic ataxia. Four of 13 were missense mutations; the remainder predicted truncated proteins. The mutations were scattered throughout the gene, and only 2 of the 13 mutations identified in our laboratory have been reported by other laboratories, so it will not be possible to screen a few "hot spots" in CACNA1A. Overall, the type of mutation, missense versus nonsense, or the location of altered or truncated amino acid residues did not predict the clinical phenotype.

Use of single point mutations in domain I of beta 2-glycoprotein I to determine fine antigenic specificity of antiphospholipid autoantibodies.

Autoantibodies against beta(2)-glycoprotein I (beta(2)GPI) appear to be a critical feature of the antiphospholipid syndrome (APS). As determined using domain deletion mutants, human autoantibodies bind to the first of five domains present in beta(2)GPI. In this study the fine detail of the domain I epitope has been examined using 10 selected mutants of whole beta(2)GPI containing single point mutations in the first domain. The binding to beta(2)GPI was significantly affected by a number of single point mutations in domain I, particularly by mutations in the region of aa 40-43. Molecular modeling predicted these mutations to affect the surface shape and electrostatic charge of a facet of domain I. Mutation K19E also had an effect, albeit one less severe and involving fewer patients. Similar results were obtained in two different laboratories using affinity-purified anti-beta(2)GPI in a competitive inhibition ELISA and with whole serum in a direct binding ELISA. This study confirms that anti-beta(2)GPI autoantibodies bind to domain I, and that the charged surface patch defined by residues 40-43 contributes to a dominant target epitope.

EVENT AND AGENT: TOWARD A STRUCTURAL THEORY OF JOB SATISFACTION

This study evaluates a theory of job satisfaction based on two facets: event and agent. These two facets were derived from a study by Schneider and Locke (1971). In the present study, event and agent were conceptualized as two domain facets of a content universe of job satisfaction. On the basis of the above definition, a radex structure was hypothesized. 104 employees from 8 different industrial organizations in Israel were interviewed. They rated (a) their job satisfaction with respect to 11 job factors, and (b) their conception of influence upon these job factors. The intercorrelation matrix of job satisfaction was treated by a Guttman Smallest Space Analysis. The empirical space was interpreted for each facet individually, and then jointly. It is apparent that when job satisfaction is defined by two domain facets, the radex structure is confirmed.
