Rademacher Complexity Bounds for a Penalized Multi-class Semi-supervised Algorithm (Extended Abstract)
Authors: Maximov Yury , Amini Massih-Reza , Harchaoui Zaid
Published: July 2018

We propose Rademacher complexity bounds for multi-class classifiers trained with a two-step semi-supervised model. In the first step, the algorithm partitions the partially labeled data and then identifies dense clusters containing k predominant classes using the labeled training examples such that the proportion of their non-predominant classes is below a fixed threshold stands for clustering consistency. In the second step, a classifier is trained by minimizing a margin empirical loss over the labeled training set and a penalization term measuring the disability of the learner to predict the k predominant classes of the identified clusters. The resulting data-dependent generalization error bound involves the margin distribution of the classifier, the stability of the clustering technique used in the first step and Rademacher complexity terms corresponding to partially labeled training data. Our theoretical result exhibit convergence rates extending those proposed in the literature for the binary case, and experimental results on different multi-class classification problems show empirical evidence that supports the theory.

Deception
Authors: Sarkadi Stefan
Published: July 2018

Recent events that revolve around fake news indicate that humans are more susceptible than ever to mental manipulation by powerful technological tools. In the future these tools may become autonomous. One crucial property of autonomous agents is their potential ability to deceive. From this research we hope to understand the potential risks and benefits of deceptive artificial agents. The method we propose to study deceptive agents is by making them interact with agents that detect deception and analyse what emerges from these interactions given multiple setups such as formalisations of scenarios inspired from historical cases of deception.

Authors: Camacho Alberto , Muise Christian , Baier Jorge A. , McIlraith Sheila A.
Published: July 2018

Automatic synthesis of software from specification is one of the classic problems in computer science. In the last decade, significant advances have been made in the synthesis of programs from specifications expressed in Linear Temporal Logic (LTL). LTL synthesis technology is central to a myriad of applications from the automated generation of controllers for Internet of Things devices, to the synthesis of control software for robotic applications. Unfortunately, the number of existing tools for LTL synthesis is limited, and using them requires specialized expertise. In this paper we present SynKit, a tool that offers LTL synthesis as a service. SynKit integrates a RESTful API and a web service with an editor, a solver, and a strategy visualizer.
Learning Deep Unsupervised Binary Codes for Image Retrieval
Authors: Chen Junjie , Cheung William K. , Wang Anran
Published: July 2018

Hashing is an efficient approximate nearest neighbor search method and has been widely adopted for large-scale multimedia retrieval. While supervised learning is more popular for the data-dependent hashing, deep unsupervised hashing methods have recently been developed to learn non-linear transformations for converting multimedia inputs to binary codes. Most of existing deep unsupervised hashing methods make use of a quadratic constraint for minimizing the difference between the compact representations and the target binary codes, which inevitably causes severe information loss. In this paper, we propose a novel deep unsupervised method called DeepQuan for hashing. The DeepQuan model utilizes a deep autoencoder network, where the encoder is used to learn compact representations and the decoder is for manifold preservation. To contrast with the existing unsupervised methods, DeepQuan learns the binary codes by minimizing the quantization error through product quantization technique. Furthermore, a weighted triplet loss is proposed to avoid trivial solution and poor generalization. Extensive experimental results on standard datasets show that the proposed DeepQuan model outperforms the state-of-the-art unsupervised hashing methods for image retrieval tasks.

Enhanced-alignment Measure for Binary Foreground Map Evaluation
Authors: Fan Deng-Ping , Gong Cheng , Cao Yang , Ren Bo , Cheng Ming-Ming , Borji Ali
Published: July 2018

The existing binary foreground map (FM) measures address various types of errors in either pixel-wise or structural ways. These measures consider pixel-level match or image-level information independently, while cognitive vision studies have shown that human vision is highly sensitive to both global information and local details in scenes. In this paper, we take a detailed look at current binary FM evaluation measures and propose a novel and effective E-measure (Enhanced-alignment measure). Our measure combines local pixel values with the image-level mean value in one term, jointly capturing image-level statistics and local pixel matching information. We demonstrate the superiority of our measure over the available measures on 4 popular datasets via 5 meta-measures, including ranking models for applications, demoting generic, random Gaussian noise maps, ground-truth switch, as well as human judgments. We find large improvements in almost all the meta-measures. For instance, in terms of application ranking, we observe improvement ranging from 9.08% to 19.65% compared with other popular measures.

Achievement goals and self-determination in adult football players – a cluster analysis
Authors: Sarmento Hugo , Marques Adilson
Published: July 2018

To better understand the relationship between aspects of motivation and performance level in adult football players, this study aimed to identify differences in motivation among different motivational profiles created by means of hierarchical cluster analysis. The participants were 304 adult football players (90 professionals, 144 semi-professionals, 70 amateurs, age: 25.4±4.6 years). Participants completed the Task and Ego Orientation in Sports Questionnaire and the Self-Regulation Questionnaire. Based on the constructs of the questionnaires, cluster analyses were performed. Chi-square was used to determine any relationships between the players and clusters. Four different clusters were identified. There was no typical motivational profile for football players of different competition levels. However, the differences in all four clusters represented specific characteristics of football players of different competition levels most represented in each respective cluster. Cluster 1, which was the most adaptive, was not related to any competition level. On the other hand, professional athletes were significantly less represented in the least adaptive motivational profile (Cluster 4). The results highlight the complex relationship between competition and sporting motivation. Identifying the motivational profile characteristics of football players who can reach higher competition levels presents itself as a future research opportunity.
Energy expenditure of type-specific sedentary behaviors estimated using sensewear mini armband
Authors: Jin Jing , Zhuang Jie
Published: July 2018

SenseWear Mini Armband, an accelerometer with multiple physiological sensors, could be a practical means to estimate energy expenditure (EE) of children and adolescents, but its validity reported for these age groups has not been consistent within the literature. EE of twenty-six healthy Chinese 12-year-old adolescents was measured simultaneously using both SenseWear Mini Armband (SWMA) and metabolic chamber (MC) during a 16-hour stay in a MC. SWMA systematically underestimated the adolescents’ EE during sedentary behaviors, resting metabolic rate (RMR), basal metabolic rate (BMR), and total EE, with the absolute error rate ranging from 14.85% to 28.65%. The SWMA significantly underestimated EE compared with MC in Chinese adolescents. However, the amount of error can be reduced by applying correction equation proposed in this study.
The effects of a soccer match on muscle damage indicators
Authors: Devrnja Antonela , Matković Branka R.
Published: July 2018

During a soccer match players perform a substantial number of explosive activities such as jumps, duels, shots and dribblings, accelerations, decelerations, changes of direction and sprints. Precisely such repetitive eccentric contractions are related to muscle damage (exercise-induced muscle damage) that is, two or three days after the match, clinically presented as muscle soreness. The aim of this research was to identify the changes in muscle damage indicators in young players after playing a soccer game. The sample of examinees was composed of 43 soccer players (16.8±1.06 years) who were divided into two groups according to their age (22 cadets aged 15.86±0.35 years and 21 U19 players aged 17.76±0.54 years). Each group played one soccer game lasting 90 minutes each. Right before and immediately after the soccer match, examinees venous blood samples were taken in order to determine the markers of muscle damage. All statistical analyses were conducted by the SPSS software. The examinees demonstrated significantly higher values of myoglobin, creatine kinase, lactate dehydrogenase, aminotransferase, alkaline phosphatase and gamma-glutamyl-transferase after the game, as well as total number of leukocytes and concentration of C-reactive protein as indicators of inflammation. The results of this research showed that, as the muscle protein concentration was increased and an inflammatory reaction also occurred, soccer matches caused muscle damage in young players.
Effects of block and daily undulating periodization on neuromuscular performance in young male handball players
Authors: Sabido Rafael , Fernández-Fernández Jaime
Published: July 2018

The purpose of the present study was to compare block periodization (BP) and daily undulating periodization (DUP) in eliciting changes in strength, jumping performance and throwing velocity in young male handball players. Fifteen players, of the same competitive level, were assigned to one of the periodization groups (DUP=9; BP=6). Pre- and post-tests included a one repetition maximum (1 RM) back squat, countermovement jump (CMJ), triple jump with the left and right leg, 20 m speed test, standing medicine ball throw, 7 m standing throw, and 9 m jumping throw. Strength training was performed twice a week throughout an 8-week period. The BP group performed training phases in the following order: hypertrophy, power strength and explosive strength; DUP alternated every week two sessions with a different focus. Total volume and intensity during the 8-week period were equal in both training groups. Despite both groups significantly improved 1 RM squat (33.3%, effect size [ES]=1.48 for DUP and 17.4%, ES=1.40 for BP) and triple jump (4-6.3%, ES=0.32-0.51 for DUP and 9.7-12.7%, ES=1.40 for BP) performance, greater gains (ES=0.96) were detected in DUP for the 9 m throwing velocity. No significant changes were found in either group for the 20 m sprint and CMJ. It can be concluded that both periodization programs elicited significant improvements in maximal strength and jumping performance in young male handball players, while DUP was more effective than BP on throwing velocity.
Sylvan's Bottle and other Problems
Authors: Proudfoot Diane
Published: July 2018

According to Richard Routley, a comprehensive theory of fiction is impossible, since almost anything is in principle imaginable. In my view, Routley is right: for any purported logic of fiction, there will be actual or imaginable fictions that successfully counterexample the logic. Using the example of ‘impossible’ fictions, I test this claim against theories proposed by Routley’s Meinongian contemporaries and also by Routley himself (for what he called ‘esoteric’ works of fiction) and his 21st century heirs. I argue that the phenomenon of impossible fictions challenges even today’s modal Meinongians.
Reflections on Routley's Ultralogic Program
Authors: Nolan Daniel
Published: July 2018

In this paper, I take up three tasks in turn. The first is to set out what Routley thought we should demand of an all-purpose universal logic, and some of his reasons for those demands. The second is to sketch Routley's own response to those demands. The third is to explore how else we could satisfy some of the theoretical demands Routley identified, if we are not to follow him in endorsing Routleyan Ultralogic as a foundational logic. As part of this third project, I articulate what seems to me a preferable way of going to respond to the challenges Routley correctly identifies: and while I doubt what I will have to say would have convinced Routley himself, I will try to show that the approach I prefer has several advantages over Routley's.
A Note on Goddard and Routley's Significance Logic
Authors: Szmuc Damian , Omori Hitoshi
Published: July 2018

The present note revisits the joint work of Leonard Goddard and Richard Routley on significance logics (namely, logics able to handle nonsignificant sentences) with the aim of shedding new light on their understanding by studying them under the lens of recent semantic developments, such as the plurivalent semantics developed by Graham Priest. These semantics allow sentences to receive one, more than one, or no truth-value at all from a given carrier set. Since nonsignificant sentences are taken to be neither true nor false, i.e. truth-value gaps, in this essay we show that with the aid of plurivalent semantics it is possible to straightforwardly instantiate Goddard and Routley’s understanding of how the connectives should work within significance logics.

Performance Expectancy, Effort Expectancy, and Facilitating Conditions as Factors Influencing Smart Phones Use for Mobile Learning by Postgraduate Students of the University of Ibadan, Nigeria
Authors: onaolapo sodiq , Oyewole Olawale
Published: July 2018

Aim/Purpose: This study examines the influence of Performance Expectancy (PE), Effort Expectancy (EE), and Facilitating Conditions (FC) on the use of smart phones for mobile learning by postgraduate students in University of Ibadan, Nigeria.

Background: Due to the low level of mobile learning adoption by students in Nigeria, three base constructs of the Unified Theory of Acceptance and Use of Technology (UTAUT) model were used as factors to determine smart phone use for mobile learning by the postgraduate students in the University of Ibadan.

Methodology: The study adopted a descriptive survey research design of the correlational type, the two-stage random sampling technique was used to select a sample size of 217 respondents, and a questionnaire was used to collect data. Descriptive statistics (frequency counts, percentages, mean, and standard deviation), test of norm, and inferential statistics (correlation and regression analysis) were used to analyze the data collected.

Contribution: The study empirically validated the UTAUT model as a model useful in predicting smart phone use for mobile learning by postgraduate students in developing countries.

Findings: The study revealed that a significant number of postgraduate students used their smart phones for mobile learning on a weekly basis. Findings also revealed a moderate level of Performance Expectancy (𝑥 =16.97), Effort Expectancy (𝑥 =12.57) and Facilitating Conditions (𝑥 =15.39) towards the use of smart phones for mobile learning. Results showed a significant positive relationship between all the independent variables and use of smart phones for mobile learning (PE, r=.527*; EE, r=.724*; and FCs, r=.514*). Out of the independent variables, PE was the strongest predictor of smart phone use for mobile learning (β =.189).

Recommendations for Practitioners: Librarians in the university library should organize periodic workshops for postgraduate students in order to expose them to the various ways of using their smart phones to access electronic databases.

Recommendation for Researchers: There is a need for extensive studies on the factors influencing mobile technologies adoption and use in learning in developing countries.

Impact on Society: Nowadays, mobile learning is increasingly being adopted over conventional learning systems due to its numerous benefits. Thus, this study provides an insight into the issues influencing the use of smart phones for mobile learning by postgraduate students from developing countries.

Future Research: This study utilized the base constructs of the UTAUT model to determine smart phone use for mobile learning by postgraduate students in a Nigerian university. Subsequent research should focus on other theories to ascertain factors influencing Information Technology adoption and usage by students in developing countries.

High Sensitive MEMS Intraocular Capacitive Pressure Sensor (Glaucoma)
Authors: Abbas Tania Mohammed , Al-Gayem Qais Kareem
Published: July 2018

Micro Electro Mechanical Systems (MEMS) are a small-scale technology that was largely adopted by the IC industry and applied to miniaturize of all systems (electrical systems, mechanical, optical, fluidic, magnetic, etc.). Minimization has been accomplished with small manufacturing processes. A Capacitive pressure sensor is simply a diaphragm-type device in which the diaphragm displacement is determined by measuring the capacitance change between the diaphragm and a metal plate that is close to it.

For this purpose, intraocular pressure sensors are important in detection and treatment of an incurable disease called glaucoma. To improve the sensitivity of the capacitive pressure sensor, low stress doped polysilicon material is used as a biocompatible material. Glaucoma is a group of eye diseases that occurs by high intraocular pressure (IOP). IOP is the pressure exerted by the ocular fluid called aqueous humor (the clear fluid inside the eye) that fills the anterior chamber of the eye

The results Shows the simulated relation between capacitance and pressure for clamped ++silicon and polysilicon clamped. It can be seen from figure that the initial capacitance for clamped p++ silicon is about 1.81 pF the capacitance varies from 1.81 to 2.162 pF for clamped p++silicon and clamped polysilicon diaphragm, respectively, so the total variation of the capacitance. This result shows the use of poly silicon material in diaphragm is high sensitivity than the p++ silicon.
FROBENIUS’ SOLUTIONS AND THE ANALYSIS OF THE TUNNELING EFFECT FOR SPIN 1/2 PARTICLE THROUGH THE SCHWARZSCHILD BARRIER
Authors: Ovsiyuk E. M. , Voynova Ya. A. , Red’kov V. M.
Published: July 2018

For a Dirac particle, the general mathematical study of the particle tunneling process through an effective potential barrier generated by the Schwarzschild black hole background is done. The study is based on the use of 8 Frobenius’ solutions of the related second-order differential equation with 3 regular and 2 irregular singularities of the rank 2. Solutions of the radial equations are constructed in explicit form, and the convergence of the involved power series is proved in the physical range f the variable (1, ). r∈ +∞ Results for the tunneling effect are significantly different for two situations: one when the particle falls on the barrier from the inside and another when the particle falls from the outside. The mathematical structure of the derived asymptotic relations is exact, however the analytical expressions for the involved convergent powers series are unknown, and a further study of penetration and reflection coefficients should be based on the numerical summation of the power series.
SOLID PHASE RECRYSTALLIZATION OF A MECHANICALLY DISRUPTED SILICON LAYER SUBJECTED TO RAPID THERMAL TREATMENT
Authors: Pilipenko V. A. , Solodukha V. A. , Gorushko V. A. , Omelchenko A. A.
Published: July 2018

Quality and reliability of integrated circuits to a great extent depend on the surface condition of silicon wafers. In view of this, great attention is paid on the aspects of their preparation prior to their formation. It is of significant interest to study the possibility of applying rapid thermal treatment for solid phase re-crystallization of a mechanically disrupted layer of the wafer working side. The objective of this work was to establish the behavior regularities of a mechanically disrupted layer subjected to rapid thermal treatment with 2 s light pulses. As samples, there were used the silicon wafers with a diameter of 100 mm, grade KDB 12 and KEF 4.5, orientation <100> after chemical-mechanical polishing subjected to rapid thermal treatment during 7 s, which ensured their heating up to 1100 °C and without treatment. The application of the methods of Auger-spectroscopy, spectral ellipsometry, X-ray diffraction made it possible to state that such treatment increases the structural flawlessness of the surface layer of silicon wafers due to a decrease in the mechanically disrupted layer, thus ensuring obtaining the atomic-flat surface.

The article presents the results of comparison of the biochemical composition of the muscles of two-year carp of two-way crosses and the breeds and lines of different-origin carp and Amur sazan. The combinations characterized by an increased level of the dry basis content, fat and protein are established in comparison with a mean-population value, a mean level of the Belarusian collection lines, import breeds and Amur sazan bred under the same conditions. The mean mass of two-year carp selected for investigation was 531.3 g within the range from 370.2 to 645.0 g mainly with a low and mean degree ofvariation. The mean level of the dry basis content of all examined crosses was 25.85 %, the maximum value of this parameter of German × three prim was 27.92 %, and the minimum value of Germany ×Lahvin scaleless was 24.08 %. The low values of the variation coefficient (1.0–9.8 %) point to a slight variation of this parameter of different mixed bred crosses.

Published: July 2018

The results of investigations in the field of existing soil loading schemes by tracks of tracked vehicles and their effect on the traction force realized by a caterpillar propulsion device are presented. The review shows that most researchers emphasize the important role of lugs in the creation of tractive effort. However, most of the existing methods of calculating the traction force on the clutch are based on one or another specific design scheme that does not depend on the loads acting on the tracks, on the combination of the parameters of the grousers and on the physical and mechanical properties of the soil. The use of these methods does not allow us to consider the sequence and alternative variants of soil disruption, and also to establish a relationship between the magnitude of the tangential force acting on the tract with a wide range of combinations of geometric parameters of the grousers, and to link it to the physical processes taking place in the soil. Consequently, these methods do not fully describe the interaction of the crawler tracks with the ground, which makes it difficult to use them to optimize the geometric parameters of the lugs. The authors proposed an analytical method for analyzing the interaction of soil with a track of a caterpillar engine based on the regularities of the theory of the limiting state of ground masses and the main provisions used in the theory of cutting soil, taking into account the revealed features of this interaction, which makes it possible to investigate the interaction of tracks of a caterpillar propulsion with soil, taking into account the multiphase and alternative options for the destruction of soil between the grousers. This method allows you to choose the parameters of the lugs, providing an improvement in traction and coupling properties of crawler tractors.

Published: July 2018

It is essential that teachers’ capabilities developing an assessment item and setting scoring criteria in educational context that emphasizing core competency-based teaching-learning. Therefore, in this study, we conduct qulaitative research on the ability to assess math competencies based on item development and items aimed at fostering competence of pre-service mathematics teachers who assess students’ math competencies. In particular, we examined socring criteria which are developed by pre-service mathematics teachers with respect to math competencies and anlayzed how pre-service teachers’ intentions were reflected in scoring criteria. As a result, many pre-service mathematics teachers selected the analytical scoring method, and almost all pre-service mathematics teachers reflected the problem-solving competency in the scoring criteria. The rate, the students who did not reflect their own assessment intention was high students who solve the problem without teachers’ question purpose was high and the math competencies was also not reflected completely in the scoring criteria. In order to suggest accurate information on learing achievement and directions for learing to Korean students and parents who are sensitive to assessment results, research on socoring criteria should be continuously carried out. In addition, pre-service mathematics teacher education institutes should make efforts to educate teachers with assessment expertise by opening various assessment related courses.

Published: July 2018

This study investigated the effects of math problem-solving and metacognition on the problem-posing type of students. Middle school students were asked to solve real-life problems and mathematical problems, and also to answer metacognitive questions before/after solving the suggested problems. And they were asked to create new problems with the solving method similar to the suggested problems. The results are followings. First, there were no such characteristics of problem-posing type in accordance with the problem-solving level. Second, in accordance with the type of given problems, there were differences in students' problem-posing. In case that students fully understood problems as the structure of the given problems was clear even though they were real-life problems unfamiliar with students, they were able to create diverse types of problems. Finally, through the metacognitive questions before/after problem-solving, students could think of conditions for solving the suggested problems. Such students with the high level of metacognitive knowledge created more similar problems in the problem-posing activity.

Effect of Transformational Leadership, Job Design, and Human Resource Practices on Job Satisfaction of Banking Staff in Pakistan
Authors: Nasreen Amira , Mehmood Khawaja Khalid
Published: July 2018

Employee job satisfaction has been one of the crucial factors behind an organization’s success. Review of literature in the field of management, leadership, and organization behavior regarding antecedents of job satisfaction indicates that job design, transformational leadership, and human resource management practices are essential antecedents of job satisfaction as accounted by a variety of researches. However, there have been limited researches that study impact of job design, transformational leadership, and HR practices on job satisfaction in one research outline. Further, literature review indicates that such research is warranted in Pakistan because there is extremely limited research on this topic in Pakistani context. To fulfil this research gap, this study took data from banking sector as this sector is considered to be essential one contributing to Pakistan economy; and job satisfaction among bank staff has always been an important concern. The study utilized final response of 170 questionnaires from various private banks in Southern Punjab, and relied on SmartPLS3.0 for analyses of data. The study suggests that job satisfaction is affected positively by HR practices and transformational leadership, whereas job design does not affect job satisfaction in the banking context. This study makes invaluable contribution to transformational leadership theory, organization behavior, and dynamic capabilities perspective through its hypotheses testing. The study recommends banks’ management to improve quality of HR practices as well as concentrate on promoting transformational leadership style in their banks.
Trade Liberalization-Trade Revenue Nexus: An Empirical Enquiry of Trade Laffer Curve of Pakistan
Authors: Ahmad Khalil
Published: July 2018

This study tries to explore the trade revenue implication of trade liberalization for Pakistan. Laffer curve approach is used to see the non-linear relationship between trade openness and trade tax revenue.  Empirical evidence shows that trade openness has constructive impact on trade tax revenue in linear term. The non-linear relationship has also been explored in the presence of other macroeconomic variables. The marginal impact of non-liner squire trade liberalization has adverse effect on trade tax revenue. In the long run, the empirical investigation proves the existence of inverted U-shaped behavior between trade liberalization and trade tax revenue in Pakistan but this behavior does not exist in short run.
