Game Usability Heuristics Evaluation Approach for Speech Therapy Mobile Application Games

In this paper, we present an approach used to evaluate speech therapy mobile application games using a usability heuristics evaluation method for speech delay children. Designing a mobile application specifically for children with speech delay is always a challenge. A well-designed user interface and game flow are vital in a therapy game to promote self-learning and therapy by exploration in the game. There have been many proposed and used usability evaluation methods, however, heuristics evaluation strategy was used in our study as this method was specifically designed and developed to evaluate mobile application games. There are three components in the heuristics models which are Game Usability, Mobility, and Gameplay. In our experiment, we were evaluating a local prototype of speech therapy mobile application using the game usability component because we focus more on the user interface designs. The target group of this study was pre-school children aged 3 to 6 years old with speech delay. Questionnaires were developed based on the game usability heuristics and distributed to their parents or caregivers. Interviews were also conducted to obtain their comments and feedbacks. The study results showed that the game usability heuristics are useful in identifying potential issues and problems in user interface designs of the prototype. In addition, the results also revealed that the heuristics strategy is useful in producing a set of effective design guidelines for mobile application games.
Diversity and regeneration status of tree species at Nainital Catchment, Uttarakhand, India

The existence of a species in a forest community largely depends on its ability to regenerate under varied environmental conditions. In the present study, effect of biotic disturbance was assessed and analysed on diversity and regeneration of pre-dominant tree species of oak forests. For this, two adjacent sites were selected in mixed oak forest zone (2100 m asl), namely, undisturbed open area (inside zoo) and moderately disturbed open area (out side zoo). Phytosociological analysis of tree and shrub layer vegetation was done and density, diversity index, Importance Value Index etc were determined for both the sites. Regeneration status of tree species was analysed by developing population structures. Species richness (tree as well as shrub) was high in disturbed site (11 to 20) as compared to protected site (9 to 11), and in both the sites the species richness was maximum at hill slope. Among the tree species Quercus floribunda was dominant with highest value of IVI in protected site. Contrary to this, Quercus lecotrichophora was dominant in disturbed site at hill base and hill slope, while Q. floribunda was dominant at hill top site. Tree density ranged from 780 to 1000 trees ha-1 in protected site and from 260 to 780 trees ha-1 in disturbed site. In both the sites, Q. leucotrichophoraand Q. floribunda have higher proportion of individual in younger girth classes (seedlings and saplings), indicating expanding type of population structure. However, conversion into higher girth classes was more prominent at protected site as compared to disturbed site. Thus, it can be concluded that oak species of Kumaun Himalayan region have ability to regenerate when anthropogenic pressures are negligible. Key words: Basal area, density, diversity, girth class, population structure, regeneration.
The Weibull Moduli of Si-Zr-C-O Fiber with Diameter Variation about the Gauge Length

Si-Zr-C-O ceramic fibers were evaluated for deriving the Weibull parameters of high accuracy. The approach in this study couples detailed measurements of the diameter along the gauge length with tensile tests. The distribution of critical defects is assumed in the two-parameter single-modal Weibull model to be homogeneous throughout the volume. In the case of ceramic fibers, the term of volume is usually replaced with gauge length assuming the uniformity of the diameter. However the diameter measurements revealed very large variation along the gauge length of each fiber. This affects the reliability of the Weibull parameters, if the parameters are correlated with the gauge length and not with the volume. Therefore, tensile samples of equal volume were made from the sections with negligible variation in the diameter. Then the Weibull moduli were calculated for the two-parameter single-modal case with the tensile results. The obtained results show that the two-parameter single-modal Weibull distribution can successfully characterize the strength of Si-Zr-C-O fibers.
Genetic clustering and parentage analysis of Western Balkan grapevines (Vitis vinifera L.)

A total of 90 grapevine samples collected in five countries of the Western Balkan region were evaluated for trueness-to-type and kinship relations based on comparative analysis with 1,130 grapevine genotypes held at the INRA "Domaine de Vassal" French Grape Germplasm Repository, using 14 microsatellite markers. In the context of the comparative analysis, twenty-four synonyms/counterparts and the putative parents for twelve Balkan accessions were identified. We discovered five pairs of homonyms, subsequently confirming the identity or parentage of three of them. Some of the examined accessions were identified either on the basis of the genotypes found in the literature, or through parentage relationships revealed in this study. For the remaining fifty accessions we were unable to establish either their pedigree or to identify them on the basis of SSR profiles available elsewhere. Finally, the Balkan genotypes that were not well classified by synonymy or parentage analysis were further studied with a Principal Coordinate Analysis to reveal genetic clustering within larger datasets of genotypes. The graphical display of the individual and group distances showed that about forty accessions (85 %) are structured within a group of Balkan and Eastern Europe genotypes and only a minor proportion resulted in admixed population assignment.
The present status of application of the plastic concepts in structural design, presented at ASCE Annual Meeting, San Francisco, October 1984

The different approaches of recognizing plastic behavior in the design of steel structures are reviewed and the design requirements that assure successful utilization of this behavior in practice are described. Partial recognition of plastic behavior is now an important part of the allowable-stress design provisions. Continuous beams and low-rise building frames are routinely designed by the plastic method, which represents a full recognition of plastic response. For the multistory frames, because of the effect of overall instability, design must be based on the stability limit load, not the plastic limit load. This complicates significantly the design process and may have affected wider adoption of the method. Inelastic behavior, however, is extensively utilized in the design of both low- and high-rise structures resisting seismic ground shaking. Some recent advances in this area are described.
Formation of mesospheric clouds on Mars: new model results based on updated parameters

Mesospheric clouds have been observed on Mars for about 15 years. Microphysical modeling studies have provided evidence that an exogenous Ice Nucleus (IN) source is needed to form these clouds. These IN are probably Meteor Smoke Particles (MSPs) as in the Earth's mesosphere. Recent studies have provided new information on the properties of the MSPs and of CO2 ice: we are presenting here updated results using these new parameters.
Agromorphological characterization and dollar spot fungus susceptibility in accessions of common bent (Agrostis capillaris L.) collected in Northern Spain

Fourteen Agrostis capillaris accessions collected in northern Spain were characterized in a trial with a lowfertilization regime, carried out in two successive years (2004 and 2005). The commercial cultivar ‘Golfin’ was included in the study as a control. All accessions and the commercial cultivar were evaluated for 11 agromorphological characteristics and susceptibility to dollar spot disease, caused by Sclerotinia homoeocarpa F.T. Bennet. The data obtained were reduced to five principal components that cumulatively explained 85.4% of the total variance. Cluster analysis was useful in identifying four groups of accessions that described 50% of the phenotypic variation among accessions. Cluster 1 consisted of four accessions with the highest resistance to dollar spot, dark green colour, late heading date and high autumn turf quality. Cluster 2 included the two earliest heading accessions, dark green colour, intermediate tolerance to dollar spot and low autumn turf quality. Cluster 3 comprised six accessions with the latest heading date, dark green colour and low tolerance to dollar spot. Cluster 4 consisted of two accessions and the ‘Golfin’ cultivar, with lightest green colour, low autumn turf quality and the poorest tolerance to dollar spot. The results of this study suggest the potential value of some of these common bent accessions collected in northern Spain for turf and forage improvement.
The Impact of the eNOS Glu298Asp Polymorphisms on Endothelial and Diastolic Function in Non-Diabetic Offspring of Diabetic Parents

Objective: The aim of the present study was to investigate the relationship of the eNOS Glu298→Asp polymorphisms with impaired flow mediated dilatation (FMD) and diastolic dysfunction in Egyptian children with family history of type-2 diabetes Mellitus (DM). Materials and methods: Brachial artery FMD and echocardiographic study were performed in 80 (mean age, 11.5 ± 2.2 years) Egyptian non-diabetic offspring of patients with DM, and 80 (mean age, 10.6+2.4 years) Egyptian non-diabetic offspring of non-diabetic parents. Analysis of the endothelial nitric oxide synthase gene polymorphism using polymerase chain reaction and restriction fragment length polymorphism. for detection of different genotype variants (Glu/Glu (GG), Glu/Asp (GT) and Asp/Asp (TT) genotype). Results: Offspring of diabetic parents showed an increase in the frequency of Glu298Asp polymorphisms, significantly higher compared with controls (P<0.0001). The FMD% was significantly correlated with impaired diastolic dysfunction in offspring of diabetic patients (r=0.435 for IVRT and r=462 for E/Em). The Glu298Asp was significantly associated with impaired FMD and elevated E/Em among non-diabetic offspring of diabetic patients (P<0.001 and <0.005). Conclusion: Glu298Asp polymorphism in the endothelial nitric oxide synthase gene was significantly associated with impaired FMD and diastolic dysfunction in non-diabetic children with family history of diabetes.
Systems Factorial Technology Explained to Humans

The study of mental processes is at the forefront of research in cognitive psychology. However, the ability to identify the architectures responsible for specific behaviors is often quite difficult. To alleviate this difficulty, recent progress in mathematical psychology has brought forth Systems Factorial Technology (SFT; Townsend and Nozawa, 1995). Encompassing a series of analyses, SFT can diagnose and discriminate between five types of information processing architectures that possibly underlie a mental process. Despite the fact that SFT has led to new discoveries in cognitive psychology, the methodology itself remains far from intuitive to newcomers. This article therefore seeks to provide readers with a simple tutorial and a rudimentary introduction to SFT. This tutorial aims to encourage newcomers to read more about SFT and also to add it to their repertoire of analyses.
Se-ing bacteria in a new light: investigating selenium metabolism in Bacillus selenitireducens MLS10

Prokaryotes metabolize selenium in two significant ways. One way prokaryotes metabolize selenium is through incorporation into the 21st amino acid selenocysteine (Sec), which is inserted into proteins co-translationally. Additionally, many prokaryotes exploit the selenium oxyanions selenite and selenate as terminal electron acceptors in anaerobic respiration. Little is known about the evolution of selenoproteins in prokaryotes. While selenate respiration has been studied in several bacteria, nothing is known about the physiology of selenite respiration. I investigated both aspects of selenium metabolism in Bacillus selenitireducens MLS10 by annotating the selenoproteome of MLS10 and constructing phylogenies of these selenoproteins to investigate the evolution of selenoproteins in the bacilli, and by obtaining the protein profiles using SDS-PAGE, determined the cytochrome content using the pyridine hemochrome assay, and tested for enzyme activity in native gels using selenite-grown MLS10 cells. My research demonstrates that the bacilli exploit Sec residues to a far greater extent than has heretofore been appreciated, that the selenoproteins exploited by the bacilli are closely related to those of the clostridia, and provides evidence that the evolution of selenoproteins in Gram-positive bacteria and the d-Proteobacteria is characterized by extensive horizontal gene transfer. Finally, my research provides evidence that selenite respiration is a distinct, inducible respiratory pathway in MLS10, and suggests future directions for further testing of this hypothesis.

Effects of a minimal reminder intervention to reduce the length of urinary catheterization and intravenous fluids therapy for internal medicine inpatients: a parallel controlled clinical trial

Objective: To assess the effectiveness of a twice-weekly simple reminder intervention in shortening the duration of urinary catheterization and intravenous fluid therapy. Methods: Design: Parallel, controlled clinical trial. Setting: Two internal medicine wards. Patients: Patients admitted to the Internal Medicine Department since October 2010 and 3, 7 and 12 months later. Intervention: A twice-weekly simple reminder intervention during the meetings of the medical-nursing team in one ward (intervention group) and no intervention in the other (control group). Measurements: Age, sex, living at home or in a nursing residence, Barthel index, Norton scale, use and duration of urinary catheterization and intravenous fluid therapy, presence of pressure ulcers, onset of delirium, Major Diagnostic Category, and length of stay. Results: 747 patients were included. On 265 of them (35.4%) urinary catheterization was used. Patients in control group hadurinary catheters inserted more frequently (39.1% vs. 31.7%; p = .03) and for a longer time [median (interquartile range) 5 (8) vs. 4 (6) days; p = . 007]; also, the catheter was left in place at discharge more frequently (15.2% vs. 10.1%; p = .04). Intravenousfluid therapy was used on 519 (69%) patients. There were no differences in use between both groups, but it was for a longerperiod in control group [4 (5) vs. 3 (5) days; p = . 001]. Conclusions: A simple face-to-face intervention during the meetings of the medical-nursing team with a twice a week reminder to withdraw unnecessary urinary catheters and intravenous fluid therapy efficiently reduces the duration of such treatments.
Large transmitting arrays for deep space uplinks, solar system radar, and related applications

NASA’s Deep Space Network is now being re-designed to provide the next generation of ground based equipment for communicating with spacecraft throughout our solar system. In the receiving direction, it seems clear that large arrays of relatively small antennas provide the most cost-effective method of increasing the interplanetary data rate by at least 100 times over present capabilities, as is now desired. In the transmitting direction, data must also be sent at increasing rates, and the best approach to this is now being studied. Two-way links are also important for supporting spacecraft navigation and radio science measurements. Furthermore, the ability to generate very high effective radiated power makes possible radar studies of planets, asteroids, and other objects. This paper describes a conceptual design for arrays of antennas that provide transmitting capability to deep space for all these purposes.

Female Leuciscus lepidus May Be a New Alternative for Fish Oil Supplements

The proximate composition of male and female Leuciscus lepidus in Beyşehir Lake was investigated. The fatty acid profiles of total lipid, phospholipid, and triacylglycerol in muscle and liver of male and female L. lepidus were evaluated by gas chromatography. Proximate analyses showed that meat of male and female L. lepidus had 15.13 ± 0.04 and 18.75 ± 0.11% fat, 20.42 ± 0.45 and 22.21 ± 0.56% protein, 65.47 ± 1.37 and 61.28 ± 1.03% moisture, and 1.51 ± 0.05 and 1.50 ± 0.03% ash, respectively. The percentage of total saturated fatty acids was higher in liver than in muscle, whereas the total polyunsaturated fatty acid (PUFA) content was the lowest in all fatty acid profiles. The phospholipids contained more PUFAs than triacylglycerol. Analysis of variance indicated significant differences () between male (47.51%) and female (49.98%) muscle PUFAs in total lipid. The proportion of omega 3 (3) to omega 6 (6) fatty acids of total lipid was 3.15 in male and 3.68 in female. The ratio is an important indicator for comparing the value of fish oil. Therefore, it was concluded that L. lepidus was considered to be a high quality product for healthy food choice. Additionally, female L. lepidus may especially be used to produce fish oil supplements from freshwater fish combined with vegetable oils.
A Majority-Based Aggregation Operator To Represent Emotional States

The Self-Assessment Manikin (SAM) is an universally used instrument of pictographic non verbal measure which is used in many emotional studies in the field of the Psychology. In these emotional studies the usual aggregation operator is the classical mean. In this paper, a new aggregation operator is proposed. This new operator, which is based on the majority concept tries to solve the distribution problems of the mean operator. This new aggregation operator is applied in a real emotional study, in which the SAM is used, achieving better results than the classical mean operator.
Morphological Variation in Selected Accessions of Bambara Groundnut (Vigna subterranea L. Verdc) in South Africa

Bambara groundnut (Vigna subterranea L. Verdc) is an underutilized crop in the African continent. It is a drought tolerant crop and fixes atmospheric nitrogen. Bambara groundnut is primarily grown for the protein content of its seeds and is mainly produced by small scale farmers at subsistence level. The objective of the study was to assess the morphological variation of landraces of bambara groundnut in South Africa. Thirty accessions of bambara groundnut were evaluated for their variability in agronomic and morphological traits. The field experiment was conducted at ARC-VOPI in Roodeplaat research farm during the 2014/2015 summer cropping season. The field trial was arranged as a complete randomized block design with three replications. Eighteen quantitative traits were recorded to estimate the level of genetic variability among accessions. The analysis of variance revealed significant differences among the phenotypic traits evaluated. The UPGMA cluster analysis based on the quantitative traits produced four distinct groups of genotypes and a singleton. Genotypes SB11-1A, SB19-1A, SB12-3B and Bambara-12 were found to possess good vegetative characters and are recommended for use as suitable parents when breeding cultivars for fodder production. Desirable yield and yield-related traits were identified in B7-1, SB4-4C, SB19-1A, Bambara-12 and SB16-5A and are recommended as suitable parental lines for bambara groundnut grain production improvement. The phenotypic characters therefore provide a useful measure of genetic variability among bambara genotypes and will enable the identification of potential parental materials for future breeding programs in South Africa.
Perfect Competition in Di ff erential Information Economies : Consistency of Incentive Compatibility and E ffi ciency

The idea of perfect competition for an economy with differential information is formalized via an idiosyncratic signal process in which the private signals of almost every individual agent can influence only a negligible group of agents, and the individual agents’ relevant signals are essentially pairwise independent conditioned on the true states of nature. The existence of incentive compatible, individually rational and Pareto efficient allocations is shown for such a perfectly competitive differential information economy with or without “common values” via simple measure-theoretic methods. Thus, the conflict between incentive compatibility and Pareto efficiency is resolved exactly, and its asymptotic version derived for a sequence of large, but finite private information economies. ∗This work was initiated in October 2003 while Yeneng Sun was visiting the University of Illinois at UrbanaChampaign.

Detecting Masquerade in Face Recognition System – A Literature survey

A masquerader is an (often external) attacker is one who, after succeeding in obtaining a legitimateuser’s credentials, attempts to use the stolen identity to carry out malicious actions.Automatic detection of masquerading attacks is generally undertaken by approaching theproblem from an anomaly detection perspective: a model of normal behaviour for eachuser is constructed and significant departures from it are identified as potentialmasquerading attempts.The most common techniqueto masquerade a face recognition system is to use a photo print or a video of a valid user to gain illegitimate access. There exist methods in literature addressing this issue. This paper presents an analysis of masquerade detection algorithms in face recognition system.
General bat activity measured with an ultrasound detector in a fragmented tropical landscape in Los Tuxtlas, Mexico

General bat activity measured with an ultrasound detector in a fragmented tropical landscape in Los Tuxtlas, Mexico. � Bat tolerance to neotropical forest fragmentation may be related to ability by bats to use available habitats in the modified environmental matrix. This paper presents data on general bat activity (for three hours starting at dusk) measured with an ultrasound detector in a fragmented landscape in the region of Los Tuxtlas, Mexico. Bat activity was measured in continuous forest, forest fragments, forest�pasture edges, forest corridors, linear strips of vegetation, citrus groves, pastures and the vegetation present in local villages. The highest bat activity rates were recorded in the villages, in forest fragments and in linear strips of vegetation. The lowest activity rates were detected in pasture habitats. Data suggest that native and man�made arboreal vegetation may be important for sustaining bat activity in fragmented landscapes.
