Determining the Ability to Use Direct Broadcast System (DBS) Data to Forecast Severe Weather

We research the capability of the direct broadcast system (DBS) received sounding radiance data for forecasting severe weather. This study is important for Hampton Roads because severe weather, such as flash floods and severe thunderstorms, is frequent in this area, and the DBS can lead to faster warnings. The DBS is located on top of the Harbor Center in Hampton, Virginia and collects data from satellites as they orbit within the line-of-sight of the receiving antenna. For this research, we focused on the Atmospheric Infrared Sounder (AIRS), Cross-track Infrared Sounder (CrIS), and Infrared Atmospheric Sounding Interferometer (IASI). These three instruments provide sounding data that produces a vertical profile of the atmosphere. The sounding data is compared to different meteorological data sets. These data sets include radiosonde data, Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR) model atmospheric profiles, and geostationary satellite Advanced Baseline Imager (ABI) data. We use statistics to understand how well the soundings created from the DBS hyperspectral radiances compare to the radiosonde, RAP, and HRRR data. We also combine ABI radiance derived sounding data with the DBS sounding data to create a data set that has the high vertical resolution provided by the DBS hyperspectral radiance observations and the much better spatial and temporal resolutions provided by the ABI multispectral radiance observations. The results show that the DBS closely matches the other meteorological data sets and combining the DBS data with the ABI data allows for more detailed and more frequent sounding data as required to improve severe weather predictions.
Study of English Code-mixing and Code-switching in Thai Pop Songs

Code-mixing and code-switching have been around for decades. While the characteristics of code-mixing and code-switching have been well-documented across a variety of languages, little is known about how they are used as communicative strategies for entertainment. This study is an attempt to fill in this gap by exploring and describing the recent phenomenon of English code-mixing and code-switching in Thai pop songs. It was discovered that the use of English codes in Thai pop songs is different from other genres of communication since they are creatively utilized to produce rhetorical and aesthetic effects. The paper investigated what kinds of English units as well as nativized English characteristics were employed as a device for the songwriting. English words were found to be common English code-mixing elements, while simple sentences were the most frequent items appearing at the level of code-switching. As for nativization, reduplication was frequently used in Thai pop songs.
Comparison between Ω'-QPP and random interleavers for space-time turbo codes using doubly iterative decoding algorithm

The performances of a low complexity doubly iterative decoder are analyzed for space-time turbo codes on a quasi-static fading channel. In order to improve them, here is used a quadratic permutation polynomial interleaver with the best Ω' metric (Ω'-QPP) and the obtained frame error rate (FER) and bit error rate (BER) performances are compared to those of random interleavers. To reduce the spatial interference of the received signal, the decoder uses preliminary soft values of the coded symbols, obtained after a limited number of turbo iterations. To improve the quality of the soft values, new turbo iterations are performed. From simulation results it can be seen that in BER domain the obtained coding gain decreases when the number of doubly iterations increases and in FER domain the obtained coding gain is more significant as the number of double iterations increases. When the number of doubly iterations increases, the number of erroneous frames decreases more than the number of errors per frame.
YMXM motifs and signaling by an insulin receptor substrate 1 molecule without tyrosine phosphorylation sites

Tyrosine phosphorylation of insulin receptor substrate 1 (IRS-1) by the activated receptors for insulin, IGF-1, and various cytokines creates binding sites for signaling proteins with Src homology 2 domains (SH2 proteins). Determining the role of specific SH2 proteins during insulin signaling has been difficult because IRS-1 possesses as many as 18 potential tyrosine phosphorylation sites, several of which contain redundant motifs. Using 32D cells, which contain no endogenous IRS proteins, we compared the signaling ability of an IRS-1 molecule in which 18 potential tyrosine phosphorylation sites were replaced by phenylalanine (IRS-1(F18)) with two derivative molecules which retained three YMXM motifs (IRS-1(3YMXM)) or the two COOH-terminal SHP2-Fyn binding sites (IRS-1(YCT)). During insulin stimulation, IRS-1(F18) failed to undergo tyrosine phosphorylation or mediate activation of the phosphotidylinositol (PI) 3'-kinase or p70(s6k); IRS-1(YCT) was tyrosine phosphorylated but also failed to mediate these signaling events. Neither IRS-1(3YMXM) nor IRS-1(YCT) mediated activation of mitogen-activated protein kinases. IRS-1(F18) and IRS-1(YCT) partially mediated similar levels of insulin-stimulated mitogenesis at high insulin concentrations, however, suggesting that IRS-1 contains phosphotyrosine-independent elements which effect mitogenic signals, and that the sites in IRS-l(YCT) do not augment this signal. IRS-1(3YMXM) mediated the maximal mitogenic response to insulin, although the response to insulin was more sensitive with wild-type IRS-1. By contrast, the association of IRS-1(3YMXM) with PI 3'-kinase was more sensitive to insulin than the association with IRS-1. Thus, the binding of SH2 proteins (such as PI 3'-kinase) by YMXM motifs in IRS-1 is an important element in the mitogenic response, but other elements are essential for full mitogenic sensitivity.
Visual Narratives of Parametric Design History Aha !

Histories are underdeveloped and underused features in parametric CAD (PCAD) systems. Designers employ backtracking and deferral strategies that both use and augment history. Using backtracking and deferral as a framework we present two classes of design process graph diagramming techniques for augmented history in PCAD. We compare the second version of these design process graphs across several designers who completed multiple tasks using two parametric systems (SolidWorks and GenerativeComponents). The two systems show similar types of action, with markedly more and deeper backtracking in GenerativeComponents. We present a third diagramming system as a design for a proof of concept prototype. This prototype aims to expand the capabilities of design histories beyond access to single prior states to visualize and enable direct interaction based on backtracking and deferral.
Transparent Self-Cleaning Coating Consisting Hydrophobically Modified-Polymer

Article history: Received 5 October 2018 Received in revised form 4 December 2018 Accepted 8 December 2018 Available online 1 January 2019 In general, hydrophobic coating is termed as the coating with water contact angle (CA) above 90 ̊. The fabrication of hydrophobic coating on the glass substrate has high potential to induce self-cleaning property, anti-fog, and oil-repellent coating. In this study, transparent self-cleaning coating of modified Polydimethylsiloxane (PDMS) has been successfully developed for glass panel application. 3aminopropyltriethoxyslane (APTES) provides a flexible amino group for reacting with the silica structure of Polydimethylsiloxane. The hydrophobic coating is applied onto glass plates through simple dip-coating method. The hydrophobicity of coating is achieved water contact angle as high as 103̊ and the transparency of the coating is above 80% in UV-Vis region. The prepared-coating also exhibit an excellent selfcleaning property which the coating completely expels the mud, dilute-ketchup solution, syrup favor, and methylene-blue dye. In addition, the coating shows great anti-fog behavior which the tiny droplets on the coating surface are completely disappears after 6 min at ambient temperature. The droplet impact testing has showed the hydrophobicity of coating is slightly decreases by 4.9° only after injecting with continuous droplet for 168h which indicated that the excellent surface durability of coating.
Relevance of the Interaction between Alphaherpesvirus UL3.5 and UL48 Proteins for Virion Maturation and Neuroinvasion

ABSTRACT The UL3.5 and UL48 genes, which are conserved in most alphaherpesvirus genomes, are important for maturation of pseudorabies virus (PrV) particles in the cytoplasm of infected cells (W. Fuchs, B. G. Klupp, H. J. Rziha, and T. C. Mettenleiter, J. Virol. 70:3517-3527, 1996; W. Fuchs, H. Granzow, B. G. Klupp, M. Kopp and T. C. Mettenleiter, J. Virol. 76:6729-6742, 2002). In bovine herpesvirus 1 (BoHV-1), the homologous gene products pUL3.5 and pUL48 have been demonstrated to interact physically (N. Lam and G. Letchworth, J. Virol. 74:2876-2884, 2000). Moreover, BoHV-1 pUL3.5 partially complemented a pUL3.5 defect in PrV (W. Fuchs, H. Granzow, and T. C. Mettenleiter, J. Virol. 71:8886-8892, 1997). By using coimmunoprecipitation and yeast two-hybrid studies, we observed a similar interaction between pUL3.5 and pUL48 of PrV, as well as a heterologous interaction between the PrV and BoHV-1 gene products. The relevant domain could be confined to the first 43 amino acids of PrV pUL3.5. Unlike its BoHV-1 homologue, PrV pUL3.5 is processed by proteolytic cleavage, and only an abundant 14-kDa fragment consisting of amino acids 1 to ≥116 could be detected by peptide mass fingerprint analysis of purified wild-type PrV particles, which also contain the pUL48 tegument component. To determine the biological relevance of the protein-protein interaction, pUL3.5-, pUL48-, and double-negative PrV mutants were analyzed in parallel. All deletion mutants were replication competent but exhibited significantly reduced plaque sizes and virus titers in cultured rabbit kidney cells compared to wild-type and rescued viruses, which correlated with a delayed neuroinvasion in intranasally infected mice. Remarkably, the defects of the double-negative mutant were similar to those of pUL48-negative virus. Electron microscopy of cells infected with either deletion mutant revealed the retention of naked nucleocapsids in the cytoplasm and the absence of mature virus particles. In summary, our studies for the first time demonstrate the relevance of the pUL3.5-pUL48 interaction for secondary envelopment of an alphaherpesvirus, give a molecular basis for the observed trans-complementation between the PrV and BHV-1 pUL3.5 homologs, yield conclusive evidence for the incorporation of a proteolytically processed pUL3.5 into PrV virions, and demonstrate the importance of both proteins for neuroinvasion and neurovirulence of PrV.
Optimal Design of 2-Phalanx Underactuated Fingers

This paper presents the optimal design of underactuated fingers considering two issues: the force isotropy of the grasp, namely its ability to generate a uniform pressure on the object seized, and its stability. First, the force isotropy property is defined and a method to achieve the latter is presented. Its robustness with respect to undesired variations of the design parameters is also discussed. Second, guidelines to minimize or completely avoid ejection are presented as well as their influence on the desired optimality. In this work, a stable grasp means that the finger is in static equilibrium. The occurence of the situations where one phalanx force is negative should be decreased (prevention may be impossible [1]) and the ejection avoided. The aim of this paper is to elaborate simple and practical design rules to obtain stable optimal fingers. Previous analyses [2, 3] have described the issue of ejection for underactuated fingers, namely that a grasp sequence can degenerate into ejecting the object, and a numerical minimization was used to obtain effective finger designs. In this paper, the concept of isotropic grasp as an optimality criterion, and also, a method to either minimize or completely eliminate ejection if a limited range of motion is acceptable, are presented. Emphasis should be placed on the fact that the optimal ejection-free design method presented in this paper differs from usual optimization, since one does not maximize a criterion but matches it exactly. The designs resulting from the method proposed are force isotropic and ejection free. Results are given for both tendon-pulley and linkage transmission.
’ s repository of research publications and other research outputs Collaboration and interference : Awareness with mice or touch input Conference or Workshop Item

Multi-touch surfaces are becoming increasingly popular. An assumed benefit is that they can facilitate collaborative interactions in co-located groups. In particular, being able to see another’s physical actions can enhance awareness, which in turn can support fluid interaction and coordination. However, there is a paucity of empirical evidence or measures to support these claims. We present an analysis of different aspects of awareness in an empirical study that compared two kinds of input: multi-touch and multiple mice. For our analysis, a set of awareness indices was derived from the CSCW and HCI literatures, which measures both the presence and absence of awareness in colocated settings. Our findings indicate higher levels of awareness for the multi-touch condition accompanied by significantly more actions that interfere with each other. A subsequent qualitative analysis shows that the interactions in this condition were more fluid and that interference was quickly resolved. We suggest that it is more important that resources are available to negotiate interference rather than necessarily to attempt to prevent it. ACM Classification
Big Data Strategy

The importance of data analysis in companies grows every day, with a global market that generates large amounts of transactions. Industry 4.0 is one of the technological trends, which is a set of diverse technologies whose objective is the digitalization and technological connectivity of the entire value chain of organizations. Data analysis and decision making in real time have a positive impact on efficiency. One of the technologies that support this concept is big data, which can support companies to use and manage large volumes of data as support in decision making. In this research project, the computational environment of Apache Hadoop software has been analyzed to create a technological strategy that supports companies in creating a roadmap to know and implement big data technology; as a result, a computer laboratory for big data has been created at the Autonomous University of Coahuila, Mexico to support medium-sized manufacturing companies in their data analysis strategy for decision making.
Text clustering algorithm based on spectral graph seriation

In the field of information processing, most of the existing text clustering algorithm is based on Vector Space Model(VSM). However, VSM can not effectively express the structure of the text so that it can not fully express the semantic information of the text. In order to improve the ability of expression in the semantic information, this paper presents a new text structure graph model. With the weighted graph, this model expresses the characteristics term of the text and its associated location information. On this basis of spectral graph seriation, a spectral clustering algorithm is put forward. This algorithm replace solving common subgraph with matrix computation, then reduce the computational complexity of graph clustering. There are also algorithm analysis and experiment in the paper. The results of the study show that the text clustering algorithm based on spectral graph seriation is effective and feasible.
Users ’ versus Preparers ’ Materiality Judgments : Risk Relevance of Climate-Change Disclosures in Form 10-K

Do firms’ Form 10-K risk disclosures meaningfully reflect the material uncertainties they face? The question is important because firms’ failure to disclose material risks may leave investors exposed to potentially significant losses. Further, investors and other stakeholders continue to raise concerns that public registrants’ 10-K filings are insufficient and boilerplate, and thus inconsistent with the requirements of Regulation S-K. We address this question with an analysis of about 3,000 climate-change risk (CCR) disclosures in 10-K filings of large public registrants over seven years. A key feature of our study is examination of users’ versus preparers’ CCR materiality judgments. Users’ judgments are proxied by the industry-based criteria for classification of CCR materiality provided by the Sustainability Accounting Standards Board’s panel of experts. Preparers’ judgments of CCR materiality are proxied by managers’ CCR disclosure choices in Form 10-K. Using cost of equity (COE) as a proxy for firm risk, we find that the COE of firms disclosing material CCR information is 21.3 basis points lower than the COE of non-disclosing firms. More importantly, and central to our materiality prediction, we find that, in industries where users judge CCR as material, the COE is 49.1 basis points lower for firms that disclose CCR information in Form 10-K than for non-disclosing firms. In contrast, we find no significant association between disclosing CCR information in Form 10-K and COE for firms in industries where users judge CCR as not-material. Our findings lend support to the concerns that managers’ failure to disclose CCR in Form 10-K imposes additional risk on firms in industries where users judge CCR as material.
Comparison of approximations in stochastic and robust optimization programs

The paper deals with two wide areas of optimization theory: stochastic and robust programming. We specialize to different approaches when solving an optimization problem where some uncertainties in constraints occur. To overcome uncertainty, we can request the solution to be feasible to all but a small part of constraints. Both approaches gives us different methods to deal with this requirement. We try to find fundamental differencies between them and illustrate the differencies on a simple numerical example. MSC 2000: 90C15, 90C25
Optimization Parameters of Multi Walled Carbon Nanotubes ’ Diameter Using Taguchi Design of Experimental Approach

In this study, the effect of operating parameters in improving the diameter of multi-walled carbon nanotubes using Taguchi Experimental Design was presented. Wet impregnation method was employed for the bimetallic (Fe-Ni) on kaolinite clay catalyst development and the MWCNTs were synthesized via catalytic vapour deposition technique. The catalyst was then characterized to determine its suitability for the synthesis of MWCNTs using Scanning Electron Microscopy (SEM), Energy Dispersion X-Ray (EDX), X-Ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) for the surface morphology, elemental analysis, crystallinity and surface functional group respectively. The results of the SEM and the EDX show that the ferrites are well dispersed on the kaolinite support while the XRD and the FTIR depict high level of catalyst crystallinity and efficient ferrite (NiFe2O3) compound for MWCNTs nucleation process. The well characterized catalyst was used for the Taguchi optimization process in a CVD reactor. The effect of reaction temperature, reaction time and acetylene flow rate were determined on the diameter of the MWCNTs produced. The pristine diameter formations of the MWCNTs produced were observed to vary between 23.6 – 57.6 nm. A L9 Orthogonal Array signal to Noise ratio and analysis of variance (ANOVA) are applied to study performance characteristics of the parameters. Reaction temperature was found to be significant factor with percentage contribution of 82.60%. Hence, wet impregnation method proved efficient for the production of catalyst in the synthesis of diameter controllable MWCNTs using Catalytic Vapour Deposition techniques.
Psychological Empowerment, Job Satisfaction and Organizational Commitment Among Lecturers in Higher Education: Comparison of Six CEE Countries

Abstract Background and Purpose: Organizations should implement new findings from the field of human resource management. If an organization wants to have successful and effective employees, they should be satisfied with all aspects of work and at the same time they should be feel commitment towards an organization. To have a full insight in employees, organizations have to take care of psychological side of employees, which manifests in psychological empowerment. Design/Methodology/Approach: The survey was conducted among 409 university lecturers in Austria, Croatia, Czech Republic, Germany, Serbia, and Slovenia. The investigated constructs of psychological empowerment, job satisfaction and organisational commitment were compared. Spreitzer’s PEQ was used for the assessment of the psychological empowerment, Spector’s JSS for job satisfaction, and Allen’s and Meyer’s OCQ for the assessment of organisational commitment. Results: The research showed that the highest level of psychological empowerment can be found among university lecturers from Serbia and the lowest from Germany. Job satisfaction level is the highest in Austria and the lowest in Slovenia. Affective organisational commitment is the highest in Slovenia and the lowest in Germany. Continuance organisational commitment scored the highest in Croatia and the lowest in Czech Republic. Additionally, the outcomes show the highest level of normative organisational commitment in Czech Republic and the lowest in Austria. Only affective organisational commitment was not found as statistically significant. Conclusion: Knowledge of psychological empowerment, job satisfaction and organizational commitment can be helpful for leaders, because with this knowledge they can manage, develop and motivate employees properly.
Post‐hatchling cranial ontogeny in the Early Triassic diapsid reptile Proterosuchus fergusi

The phylogenetic position of Proterosuchus fergusi (Lower Triassic of South Africa) as one of the most basal archosauriforms means that it is critically important for understanding the successful evolutionary radiation of archosaurs during the Mesozoic. The excellent sample of the species provides a unique opportunity to understand early archosauriform ontogeny. Qualitative and quantitative analyses of cranial ontogenetic variation were conducted on an ontogenetic sequence, in which the smallest individual is 37% of the size of the largest one and osteohistological evidence suggests that four of 11 collected specimens had not reached sexual maturity. Through ontogeny the skull of Proterosuchus became proportionally taller, the infratemporal fenestra larger, and the teeth more isodont and numerous but with smaller crowns. The sequence of somatic maturity supports relatively high growth rates during early ontogeny. The skull of juvenile specimens of Proterosuchus closely resembles adults of the basal archosauromorph Prolacerta, whereas adult specimens resemble adults of more derived archosauriforms. As a result, a plausible hypothesis is that ontogenetic modification events (e.g. heterochrony) may have been key drivers of the evolution of the general shape of the skull at the base of Archosauriformes. These changes may have contributed to the occupation of a new morphospace by the clade around the Permo‐Triassic boundary.
