Theory of particle swarm optimization: A survey of the power of the swarm’s potential
Authors: Bassimir Bernd , Raß Alexander , Schmitt Manuel 
Published: October 2019

Abstract
This paper presents a survey on different showcases for potential measures on particle swarm optimization (PSO). First, a potential is analyzed to prove convergence to non-optimal points. Second, one can apply a minor modification to PSO to prevent convergence to non-optimal points by using an easy potential measure. Finally, analyzing this potential measure yields a reliable stopping criterion for the modified PSO.
Assessment of inner reliability in the Gauss-Helmert model
Authors: Ettlinger Andreas , Neuner Hans 
Published: October 2019

Abstract
In this contribution, the minimum detectable bias (MDB) as well as the statistical tests to identify disturbed observations are introduced for the Gauss-Helmert model. Especially, if the observations are uncorrelated, these quantities will have the same structure as in the Gauss-Markov model, where the redundancy numbers play a key role. All the derivations are based on one-dimensional and additive observation errors respectively offsets which are modeled as additional parameters to be estimated. The formulas to compute these additional parameters with the corresponding variances are also derived in this contribution. The numerical examples of plane fitting and yaw computation show, that the MDB is also in the GHM an appropriate measure to analyze the ability of an implemented least-squares algorithm to detect if outliers are present. Two sources negatively influencing detectability are identified: columns close to the zero vector in the observation matrix B and sub-optimal configuration in the design matrix A. Even if these issues can be excluded, it can be difficult to identify the correct observation as being erroneous. Therefore, the correlation coefficients between two test values are derived and analyzed. Together with the MDB these correlation coefficients are an useful tool to assess the inner reliability – and therefore the detection and identification of outliers – in the Gauss-Helmert model.

Abstract
The evaluation of geoscience data is a far-reaching topic which cannot be systematically covered. The purpose of inferential statistics is to harness useful information from data for making decisions. This paper conducts in-depth statistical study for the Bursa-Wolf and Molodensky Badekas models of the three-dimensional transformation parameters. We also considered the combined and observation equations scenarios of these methods for the comparative study. Four key indicators are conducted to evaluate the performance of the two transformation models according to the residual results. These include root mean square error (RMSE), paired t-test, Wilcoxon signed-rank test and the Cohen’s d effect size measure. RMSE evaluation is based on the mean difference between model estimates and observed values. The correlations in the model results is investigated based on paired t-test. Wilcoxon signed-rank test assesses the statistical significance of the model’s paired differences. To estimate the effect size of the performance differences, Cohen’s d measures are computed. Further, the residuals of the estimated parameters are plotted according to their respective control points. The inference results of these tests generally show that Badekas transformation approach is more precise than Bursa-Wolf. Specifically, Badekas combined case is the most precise, followed by its observation case, then Bursa-Wolf combined and finally its observation case is the least performing model. The application of various data analysis and statistical verifications make the task of data interpretation and best model selection easier.
Varying social roles and networks on a family farm: Evidence from Swedish immigrant letters, 1880s to 1930s
Authors: Hoffman Angela , Kytö Merja 
Published: October 2019

Abstract
The present study investigates patterns of language use in the ego documents written by three Swedish immigrants: Nils Blomberg (born in 1839), Mathilda Blomberg, (b. 1863), and Anton Blomberg (b. 1885), their eldest son. The empirical foundation of the investigation is a set of 32 family letters sent over a period of nearly fifty years (1885–1934) from the rural Smoky Valley in Kansas to Mathilda’s home village in Östergötland, Sweden. We analyze the writers’ lexis, discourse patterning (formulaic versus free-flowing), and re-current topics, and the social roles and networks that are manifest in their correspondence. The three writers continued to correspond in the Swedish language over the years. Our diachronic analysis of their lexis and discourse patterning reveals individual variation across the authors’ production. For example, Mathilda’s correspondence contains some evidence of heritage Swedish (i.e. Swedish that has diverged from the home country, due to geographical separation and language contact with English). Across her lifespan, Mathilda integrates some vocabulary for plants, places, and jobs that diverges from the lexis she recalls from her early years in Sweden, and she draws attention to this lexical divergence for the sake of her readers. Anton, a childhood bilingual in Swedish and English, systematically translates English lexis to Swedish in letters, presumably with the goal to bring his Kansas experiences closer to his Swedish relatives. In particular, the letters, especially those by Mathilda, reveal not only how the individuals communicate information about their social roles in rural Kansas, but also their desires to maintain the networks connecting their family farm in the U.S. to Mathilda’s home village in Sweden.
Canadian heritage German across three generations: A diary-based study of language shift in action
Authors: Stolberg Doris 
Published: October 2019

Abstract
It is well known that migration has an effect on language use and language choice. If the language of origin is maintained after migration, it tends to change in the new contact setting. Often, migrants shift to the new majority language within few generations. The current paper examines a diary corpus containing data from three generations of one German-Canadian family, ranging from 1867 to 1909, and covering the second to fourth generation after immigration. The paper analyzes changes that can be observed between the generations, with respect to the language system as well as to the individuals’ decision on language choice. The data not only offer insight into the dynamics of acquiring a written register of a heritage language, and the eventual shift to the majority language. They also allow us to identify different linguistic profiles of heritage speakers within one community. It is discussed how these profiles can be linked to the individuals’ family backgrounds and how the combination of these backgrounds may have contributed to giving up the heritage language in favor of the majority language.
Historical heritage language ego-documents: From home, from away, and from below
Authors: Brown Joshua R. 
Published: October 2019

Abstract
Recent research into heritage languages has shown the results of language contact structurally and socially. This work is almost exclusively synchronic. This special issue presents five papers that look at the historical record of language contact in migration contexts. In using ego-documents written by everyday users of the languages in contact, we uncover the usefulness of incorporating historical sociolinguistic analysis into heritage language research.

Abstract
All-optical processor capable of processing optical bits has been a long-standing goal of photonics. In this paper, we report the results obtained by numerical simulations regarding the designing of an all-optical combinational circuit of an adder and subtractor circuits based on Si3N4 microring resonators. The designs of combinational circuit like adders and subtractor based on the use of all-optical basic logic gates are discussed while presenting the numerically simulated results. Extinction ratios of 5.2 dB, 3.5 dB and 2.7 dB are obtained for the half adder, full adder and half subtractor, respectively.
Power Enhancement of the U-shape Cavity Microring Resonator Through Gap and Material Characterizations
Authors: Amiri IS , Rashed Ahmed Nabih Zaki 
Published: October 2019

Abstract
A U-shape cavity including the microring resonator with a radius of 3 µm has been modeled and studied for the throughput and drop output power enhancement of the microring resonator. We have obtained the maximum output power of the silicon microring resonator by varying the bandgap between the microring and the coupled bus waveguides. The outputs can be further affected by using the different semiconductor materials such as GaAs and InAs as core waveguides, which show significant power enhancement at the throughput and drop, respectively. A time delay of 347 fs is realized for the generated results, which is occurred due to the different light propagation patch.

Authors: Amiri I. S. , Rashed Ahmed Nabih Zaki , Jahan Sohely , Paul Bikash Kumar , Ahmed Kawsar 
Published: October 2019

Abstract
This study presents the polar polarization mode and average radical intensity flux distribution measurements based on all optical spatial communication systems. The numerical technique that is applied with the simulation model is the diffraction fast Fourier integral transform. Spatial optical sources are used such as continuous wave (CW) laser and vertical cavity surface-emitting laser (VCSEL) with spatial connector and spatial aperture. Spatial temporal polarization effects are taken into account. Percentage encircled flux/average flux radical intensity and polar radical polarization are measured with spatial connector distance and spatial aperture width. The encircled flux is constant at 95 % of its value in the case of VCSEL laser source at a radical distance of exactly 10 μm. However, the encircled flux is constant at 92 %of its value in the case of CW laser source at a radical distance of exactly 6 μm. It is noticed that the encircled flux increases with increasing radial distance of spatial apertures that are used with two suggested light sources. The encircled flux is constant at 93 % of its value in the case of VCSEL laser source at a radical distance of exactly 10 μm.

Published: October 2019

Abstract
High-speed single-mode fiber-optic communication systems have been presented based on various hybrid multiplexing schemes. Refractive index step and silica-doped germanium percentage parameters are also preserved during their technological boundaries of attention. It is noticed that the connect design parameters suffer more nonlinearity with the number of connects. Two different propagation techniques have been used to investigate the transmitted data rates as a criterion to enhance system performance. The first technique is soliton propagation, where the control parameters lead to equilibrium between the pulse spreading due to dispersion and the pulse shrinking because of nonlinearity. The second technique is the MTDM technique where the parameters are adjusted to lead to minimum dispersion. Two cases are investigated: no dispersion cancellation and dispersion cancellation. The investigations are conducted over an enormous range of the set of control parameters. Thermal effects are considered through three basic quantities, namely the transmission data rates, the dispersion characteristics, and the spectral losses.

Authors: Kumar Ghanendra , Kumar Chakresh 
Published: October 2019

Abstract
In this review paper, the turbulence of the channel through which the light photons are scattered has been modeled. The channel here is essentially the lower lithosphere. A two-step algorithm called the Method of Expectation–Maximization has been used for the analysis and calculations of the parameters involved. Statistical methods have been used to check temporal correlation and the tolerance of the communication system involved. The simulations and results have been presented and the conclusions show decent performance. The approaches have been applied to the UV scattering channel experiment, NLOS experiment and for link gain at a distance of 0.5 km.

Published: October 2019

Abstract

Purpose
To determine the workspace through an anatomical dimensional study of the skull base to further facilitate the design of the robot for endonasal endoscopic transsphenoidal (EET) surgery.

Methods
There were 120 cases having a paranasal sinus CT scan in the database. The internal volumes of the nasal cavities (NC), the volumes of the sphenoid sinuses (SS), and the distance between the anterior nasal spine and base of the sellar (d-ANS-BS) were measured.

Results
The Pearson correlation coefficient (PCC) between the relevant distances and the volumes of the right NC was 0.32; between the relevant distances and the volumes of the left NC was 0.43; and between the relevant distances and volumes of NC was 0.41; with a statistically significant difference (p < 0.001). All PCCs had a statistically significant meaningful difference (p < 0.05).

Conclusion
The volume of NCs were significantly correlated with distances (p < 0.05). The safest and shortest distance to guide the robotic arm length in the EET approach could be represented by d-ANS-BS. This result was also used as primary information for further robotic design.
Non-surgical removal of dens invaginatus in maxillary lateral incisor using CBCT: Two-year follow-up case report
Authors: Pradhan Babita , Gao Yuan , He Libang , Li Jiyao 
Published: October 2019

Abstract
A 14-year female presented with an atypical looking tooth #7 with a sinus tract on tooth #8. A gutta-percha point inserted into the sinus tract confirmed the affected tooth #7. A radiographic examination of tooth showed a lateral radiolucency with respect to tooth #7. Cone-beam computed tomographic imaging was done for the three-dimensional reconstruction analysis. Dens invaginatus (Oehler’s type III) with pulp necrosis and chronic apical periodontitis was the definitive diagnosis. Use of the dental operating microscope and ultrasonics helped in the removal of the invaginated structure. At the two year follow-up, no clinical and radiographic evidence of infection was observed.

Deontic and epistemic necessity in Turkish sign language (TİD)
Authors: Özkul Asli 
Published: October 2019

AbstractThis study investigates two flavors of the necessity modal sign NECESSARY in TİD and investigates their semantic and syntactic properties and how these properties interact. First, the modal flavors of this modal sign were identified through the contexts they occur in, based on the analysis by Kratzer (1981, 1991). Epistemic and deontic flavors of modality were searched for in the data, which was collected by spontaneous and semistructured elicitation tasks. Then, questionnaires that involve felicity and grammaticality judgment tasks were carried out to explore the semantic and syntactic properties of these modal signs in more detail. A total of 29 TİD signers participated in the data collection. The results of this investigation show that (i) NECESSARY is a necessity modal sign which has both epistemic and deontic interpretations, (ii) NECESSARY has a restricted syntactic position in a clause, (iii) non-manual markers differentiate between the epistemic and deontic interpretations of NECESSARY, which indicates that non-manual markers in TİD have both syntactic and prosodic functions.
Conversion in Albanian
Authors: Paçarizi Rrahman 
Published: October 2019

Abstract
Conversion is a unique way of forming new words, when derived word has the same shape as the original word. In traditional grammars, quite dominant is the definition that during conversions there is a change in the belonging of the part of speech or at least the change of the syntactic category of the word, without any change in the shape. The morpho-syntactic approach is based solely on changing the part of speech, while the lexical approach relies on the creation of the new lexical unit. This paper is an effort to expanded approach and perspective, because conversion in Albanian occurs also within the same parts of speech, or without changing it. While in English and German conversion is one of the most productive ways of word formation, in French, Spanish and Slavic languages it hardly exists. Italian applies conversion in a slightly different way. Albanian, on the other hand, is extremely advanced in this respect, since we have identified more than 500 cases of undoubted conversion as well as hundreds of cases of polysemy with a tendency of dissolution with high chances of differentiation of meaning, making those words new lexical units.
Metaphors in Polish wine discourse: A corpus approach
Authors: Zawisławska Magdalena , Falkowska Marta 
Published: October 2019

AbstractThis paper presents various types of metaphors within the emergent wine discourse in Polish. The analysis is corpus-based and it employs examples excerpted from Synamet – a semantically and morphosyntactically annotated corpus of Polish synesthetic metaphors. Polish wine discourse is juxtaposed against other thematic types of discourse included in the corpus, e.g., texts devoted to perfume, beer, or music, in order to point to their specificity with respect to metaphorical productivity. This comprehensive study of metaphorical expressions and the statistical analysis of the corpus clearly show which source frames are predominant in the conceptualization of wine taste, and which frame elements are most frequently activated. Apart from lexicalized metaphors, which constitute a significant part of Polish metaphorical expressions in wine discourse, we have observed many instances of creative elaboration of basic metaphorical images. Polish wine discourse also abounds with atypical metaphors that cannot be fully accounted for in terms of cross-domain mappings. These textual phenomena include layered metaphors, mixed metaphors, and narrative metaphors. The results of the analysis undermine the attempts to create a universal model of synesthesia in language, and call into question the existing models of source-to-target mappings for synesthetic metaphors.
Utilization of tailings in cement and concrete: A review
Authors: Gou Mifeng , Zhou Longfei , Then Nathalene Wei Ying 
Published: October 2019

AbstractOne of the advantages of cement and the cement concrete industry in sustainability is the ability to utilize large amounts of industrial solid wastes such as fly ash and ground granulated blast furnace slag. Tailings are solid wastes of the ore beneficiation process in the extractive industry and are available in huge amounts in some countries. This paper reviews the potential utilization of tailings as a replacement for fine aggregates, as supplementary cementitious materials (SCMs) in mortar or concrete, and in the production of cement clinker. It was shown in previous research that while tailings had been used as a replacement for both fine aggregate and cement, the workability of mortar or concrete reduced. Also, at a constant water to cement ratio, the compressive strength of concrete increased with the tailings as fine aggregate. However, the compressive strength of concrete decreased as the replacement content of the tailings as SCMs increased, even whentailings were ground into smaller particles. Not much research has been dedicated to the durability of concrete with tailings, but it is beneficial for heavy metals in tailings to stabilize/solidify in concrete. The clinker can be produced by using the tailings, even if the tailings have a low SiO2 content. As a result, the utilization of tailings in cement and concrete will be good for the environment both in the solid waste processing and virgin materials using in the construction industry.
Bayesian analysis of periodic asymmetric power GARCH models
Authors: Aknouche Abdelhakim , Demmouche Nacer , Dimitrakopoulos Stefanos , Touche Nassim 
Published: October 2019

Abstract
In this paper, we set up a generalized periodic asymmetric power GARCH (PAP-GARCH) model whose coefficients, power, and innovation distribution are periodic over time. We first study its properties, such as periodic ergodicity, finiteness of moments and tail behavior of the marginal distributions. Then, we develop an MCMC algorithm, based on the Griddy-Gibbs sampler, under various distributions of the innovation term (Gaussian, Student-t, mixed Gaussian-Student-t). To assess our estimation method we conduct volatility and Value-at-Risk forecasting. Our model is compared against other competing models via the Deviance Information Criterion (DIC). The proposed methodology is applied to simulated and real data.
