A Modified Q-Learning Algorithm in Games

A Modified Q-Learning Algorithm in Games Yatao Wang Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2014 This thesis presents a modified Q-learning algorithm and provides conditions for convergence to a pure Nash equilibrium in potential games. In general Q-learning schemes, convergence to a Nash equilibrium may require decreasing step-sizes and long learning time. In this thesis, we consider a modified Q-learning algorithm based on constant step-sizes, inspired by Joint Strategy Fictitious Play (JSFP). When compared to JSFP, the Q-learning with constant step-sizes requires less information aggregation, but only reaches an approximation of a Nash equilibrium. We show that by appropriately choosing frequency dependent step-sizes, sufficient exploration of all actions is ensured and the estimated equilibrium approaches a Nash equilibrium.

Taxonomic implication of AFLP fingerprinting in selected polygonaceous species.

Amplified Fragment Length Polymorphism (AFLP) was used for the first time to demonstrate the relationship among 28 accessions of 13 species belonging to 4 genera of Polygonaceae. Single primer was used to amplify AFLPs and fragments were separated in 6% denaturing acrylamide gels. A total of 131 fragments were analyzed. The AFLP knowledge was found to be sufficiently susceptible to identify small level of variations and could differentiate highly interrelated genotypes. According to present study, this marker system does not support the distinction of Persicaria glabra (Willd.) M. Gomes and Persicaria hydropiper (L.) Spach as a separate species of single genus. No ultimate genus level relationships was seen, owing to very low bootstrap support for branches connecting the different clusters in the tree, all four genera did not occupy distinct positions to form separate clusters and representatives of all genera are intermingled throughout the tree except the genus Polygonum L. Position of Persicraia lapthifolia (L.) S. F. Gray and Persicaria barbata (L.) Hara is also unresolved, as both of these did not show any relationship with other species. These results will form the base for further analysis of the family by AFLP marker system.
Sweep‐Based Plausible Elastic Deformations

We present a simple and efficient technique for a plausible elastic deformation of three‐dimensional objects. An elastic sweep surface is constructed by interpolating key cross sections with positions, orientations, and boundary shapes determined by physical simulation of simple mass‐spring systems. The deformable parts of an object are approximated by the elastic sweep surfaces, and the vertices of the deformable parts are bound to nearby sweep surfaces. As an external force is applied, the corresponding parts of an object change their shapes elastically. We demonstrate the effectiveness of our technique and show its real‐time performance on mesh objects.
Risk of Musculoskeletal Complications in Cancer Patients Treated with Nivolumab

Object: We performed a meta-analysis of the risk of selected musculoskeletal toxicities associated with the PD-1 inhibitor Nivolumab versus other drugs. Methods: Several databases were searched. We assess the relevant articles and relative risks (RRs) with 95% confidence intervals (95% CIs) were estimated regarding the risk of arthralgia, asthenia, myalgia and extremity pain and Nivolumab versus control. Heterogeneity, sensitivity analysis and publication bias of the included studies were also analyzed. Results: There were 5 eligible studies, including 2220 patients that were considered in the present metaanalysis. The RRs of arthralgia, asthenia, myalgia and extremity pain were 1.116 (95% CI: 0.669, 1.860; p=0.675), 0.846 (95% CI: 0.657, 1.090; p=0.197), 0.658 (95% CI: 0.141, 3.062; p=0.593), 1.037 (95% CI: 0.647, 1.662; p=0.882), respectively. Conclusion: Our results suggested that PD-1 inhibitor Nivolumab was not associated with an increased risk of musculoskeletal toxicities including arthralgia, asthenia, and myalgia and extremity pain compared with control.
Internationalization and Performance of Emerging Market Firms: Institutional Embeddedness in Advanced Economies

AIB Insights Vol. 13, No. 3 the woRld is fascinated with emerging market (EM) firms that are starting to establish a global presence. These are firms that have been able to survive and grow despite various “institutional voids” (Khanna & Palepu, 1997) in their home countries and have managed to attract the capital and talent necessary to start internationalizing. Nevertheless, they often lag behind global competitors in brand names, innovation processes, technology, and management systems. Many of these EM firms are searching for ways to catch up by making acquisitions in advanced economies (Madhok & Keyhani, 2012).
Intelligent Traffic System: Road Networks with Time-Weighted Graphs

Driving direction traffic Systems are becoming needed systems among many Geographical Information systems (GIS’S) by many kinds of users. Yahoo maps, MapQuest, and Google Earth are examples of online Internet applications. Vehicles GPS or what is known as navigation systems are also examples. Calculating the best driving path (shorter in distance or faster in time) between two addresses is subject to many factors. Some of these factors are distances, road situation, road traffic and others. This paper presents the driving traffic problem and a solution for finding an efficient path between two points (addresses) having a number factors. It discusses spatial databases, current solutions, and finally presents a smart solution that is an extension previous solution using A* (an artificial intelligent algorithm) and A*Traffic (a variation of A*, proposed in a previous paper). The new solution uses time as the main factor in the graph representing the road network.
Extraction And Characterization of Pectin From Guava Fruit Peel .

The main objective of this research was to determine a practical follow-up to the extraction of pectin from Guava Fruit Peel and to characterize it in a laboratory, aiming at establishing the optimum conditions for acid extraction and to explore its potential for commercial production of pectin. Pectin was extracted from Guava peel powder using two different acids (HCl and Citric Acid) and at three different temperatures, time and pH viz (65, 75 & 85°C), (30,45 & 60min), (2.0,2.5 & 3.0pH) respectively. Pectin yield extracted by using Hydrochloric acid and Citric acid as reagent medium varied from 3.87% to 16.8% and 2.65% to 11.12% respectively. The best extraction condition by both the extraction reagents showed higher in yield by using Hydrochloric acid at 85°C, 60min, 2.0pH. The isolated pectin using Hydrochloric acid and Citric acid as reagents contained 685.3 and 345.4 equivalent weight, 4.25 and 3.50% methoxyl content, 67.4% and 82.1% anhydrouronic acid respectively. The degree of esterification of extracted pectin showed 52.85% and 44.3% for Hydrochloric Acid and Citric acid respectively indicating pectin obtained is low methoxyl pectin . The ash and moisture content of isolated pectin Using hydrochloric acid and Citric acid were found to be (1.8%, 3.2%) and (8.2%, 6.0%) respectively. The sensory quality of jelly developed by using pectin obtained by Citric acid Extraction was found to be the best.
Hands-on Experiments in Dynamic Systems and Control With High Student Throughput

Increased student enrollment with limited instructional resources poses significant challenges when attempting to meet the goal of hands-on experiences in system dynamics and control experiments in a mechanical engineering curriculum. A single-credit, co-requisite required laboratory course in system dynamics and control is redesigned to effectively quadruple throughput of student participation and credit-earning potential from prior course offerings. The strategy to accomplish this goal is described in this paper, as are examples of the experiments, activities related to the experiments, and the methods of assessment.
Data Migration from Grid to Cloud Computing

The advance of information and communication technologies over the last decade has improved the quality of healthcare and medical services tremendously. Especially, the people living in the countryside or remote areas benefit the most from telemedicine and emergency services. Our Health Grid is one of the test beds which provide various health-related Web services associated with mobile devices and physiological data acquisition and analysis instruments. As the number of new applications being developed increases rapidly, the ever-growing volume of collected data and real-time demand of analysis result have driven the architectural migration from Grid to Cloud Computing much sooner than we expected. Our challenge is to make the transition cost effective. This paper describes the data access migration from a relational database to Apache's HBase - one of the cloud databases. Our contribution is to minimize the required change of software for data access. Since the SQL commands of the relational database cannot be used in HBase, various mechanisms for translation and mapping between two sides must be developed. In addition, the services provided by the Web programs in Health Grid are written in various kinds of Web language while HBase does not support the access authority to these Web languages. To reduce the effort of modifying the source code for accessing HBase, we propose the use of Web services as the communication interface between various Web programs and necessary facilities to execute SQL commands in HBase. Although this is a hard engineering work, our results show that the proposed approaches are feasible and cost effective for the development teams at academic institutes. With this preliminary study, our next step is to improve our methods to take advantage of the efficient functions of HBase in processing the large amount of data.
Oceans of the brain

Examination of regional cerebral blood flow is limited by shortcomings inherent in existing neural imaging tech-niques. In this perspective, we identify problems associated with accurate diagnosis; polytypicality of symptoms, especially in aphasia; and suggest that the brain’s responses to acoustic stimuli may provide a fruitful direction for future research. We employ models from oceanography, such as Acoustic Doppler Current Profilers to illu-strate techniques which may inform new ways to examine arterial blood flow.
The Relationship Between Individual and Group Creative Behaviors

The purpose of this study is to examine the relationship between individual and group creative behaviors. Creativity is defined as the interaction among aptitude, process, and environment by which an individual or a group produces a perceptible product that is both novel and useful (Plucker et al. 2004). Group creativity are performed via brainstorming and group meetings (Reiter-Palmon et al., 2012). Data was collected from 108 Indonesian college students. Individual creative behaviors were measured via the activity checklist developed by Runco et al.(2001). Group creative behaviors were evaluated by the self-reported scale that clearly reflected the process to generate ideas in group activities. Factor analysis found five factor solutions for group creative behaviors. Linear regression analysis found that Runco’s individual creative behaviors exerted the significant influences on four out of five group creative factors, i.e., collaborative, originality, ingenious, and self-confidence. Theoretical and practical implications are considered. Key W ords: Individual Creative Behavior, Group Creative Behavior
Adoption of Social Networking Tools in Public University Libraries in Ghana

The current dynamics of information and the recent technological revolution has compelled academic libraries worldwide to embrace web technologies. The focus of this study is to assess the extent of utilisation of social networking tools adopted in the well-resourced public universities in Ghana. The study used quota sampling to select 32 professional librarians from UG, KNUST, UDS and UCC to answer questionnaires. Simple descriptive tools such as charts and percentage tables were used to present the findings of the study. The study exposed that, the most utilised social networking tool used among professional librarians was Facebook then Instant messaging. However, librarians were aware and sometimes use LinkedIn, Twitter, Blogs, Wikis, Flickr, Slideshare, and YouTube, Professional librarians used social networking tools for dissemination of library news, library events, group discussion, general library information, sharing e-resources, and offering library resources. Therefore, it was recommended that professional librarians should be encouraged to use the social networking tools for their intended purposes and observe all ethics regarding it use. Also, the libraries should be stocked with adequate ICT infrastructure and vibrant internet connectivity to ensure proper functioning and effective usage of networking tools.
CREATING 3D WRL OBJECT BY USING 2D D ATA

This paper presents a technique for Creating 3D object by using 2D images by calibration at different angles. The goal of this study is to investigate the construction of 3D graphical models of real objects in a controlled imaging environment and present the work done based on Eigen values and Eigen vectors. Although many parts of the whole system have been well known in the literature and in practice. Based on a multi-images calibration, an algorithm is designed to extract the common features of the images. Furthermore, this can be extended to estimate robustly the initial Eigen values of the object to be modeled. This algorithm has a simpler visibility check. Besides, in order to construct the appearance, we use the application of images based rendering. The reconstruction results are shown both on real world objects.
Multilevel structural equation models for longitudinal data where predictors are measured more frequently than outcomes: an application to the effects of stress on the cognitive function of nurses

Ecological momentary assessment is used to measure subjects' mood and behaviour repeatedly over time, leading to intensive longitudinal data. Variability in ecological momentary assessment schedules creates an analytical challenge because predictors are measured more frequently than responses. We consider this problem in a study of the effect of stress on the cognitive function of telephone helpline nurses, where stress is measured for each call and cognitive outcomes are measured at the end of a shift. We propose a flexible structural equation model which can handle multiple levels of clustering, measurement error, time trends and mixed variable types.
Integration of environmental education in science curricula in secondary schools in Benin, West Africa: Teachers’ perceptions and challenges

The first purpose of this descriptive study was to provide information regarding implementation of the compulsory science curricula in secondary school settings in the Republic of Benin in West Africa in which were infused elements of environmental education (EE). The second was to investigate science teachers’ attitudes towards teaching environmental topics, as well as specifics regarding self-efficacy, teaching practices, and perceived barriers in teaching EE. A Likert-style survey was administered to a total of 537 secondary school science teachers composed of two subpopulations. Ten teachers (5 SPCT and 5 BES teachers) were interviewed. A mixed methods research design was utilized to provide a fuller understanding of participants’ responses. The findings of this study showed that: (1) all teachers indicated strong support for the importance of EE for secondary science students; (2) BES teachers reported significantly greater Personal Efficacy than did their SPCT colleagues; no significant difference between BES and SPCT on the Teaching efficacy scale; (3) teachers indicated use of a diverse set of instructional strategies; (4) teachers had a mean response in the moderate range to perceived barriers; and (5) the BES teachers had a statistically significant lower mean for perceived barriers than did the SPCT teachers. Science teachers’ empowerment to teach EE issues in their class and the requirement for these topics in teacher education and professional development programs are the major implications derived from the study. Finally, suggestions for further research related to these topics are offered.
Analysis of MMSE-Based Anti-Interference Performance for MIMO-UWB Systems

The combinations of MIMO (Multiple-Input-Multiple-Output) and UWB (Ultra-Wide-Band) systems greatly improve the performance of the UWB system. For the MIMO-UWB system, a new decoding scheme is proposed based on the STF (Space-Time-Frequency) coding and it can reduce the decoding complexity. The simulation results show that under the same SNR, the new method can obtain better performance of the bit error rate than the traditional ML decoding method.
Quantitative Analysis of Impression of Robot Bodily Expression based on Laban Movement Theory

A set of physical feature values is proposed in order to explain impression produced by bodily expression. The concept of designing the value set is based on Laban Movement Analysis which is a famous theory in body movement psychology. Impressions produced by body expression are closely related to these feature values. Each of the feature values is defined mathematically, so that it is easy to implement in a computer. Also the feature values are calculated on general body movements. Therefore, the set can be implemented in body expression systems of robots and computer graphics bodies in order to facilitate quantitative evaluation and forecast of impression produced by their bodies. This paper describes the concept and an example of implementation on a robot. Validity of the set is verified in an experiment.
Social Interactivity and Its Impact on a User's Approach Behavior in Commercial Web Sites: A Study Case of Virtual Agent Presence

The purpose of the current research is to investigate the impact of social interactivity (the presence of virtual agents in a commercial web site) on the approach behavior. The experimental study was deemed to be the most relevant for collecting data. The study revealed that indeed the presence of virtual agents in a commercial web site has a positive impact on the perceived interactivity which in itself helps increasing the state of flow.
Influence of food composition on the biokinetics and tissue distribution of zinc and americium in mussels

A series of radiotracer experiments was conducted to investigate the influence of food type on the biokinetics of zinc and americium in the common mussel Myfilus edulis. Four types of food a diatom, a green alga, glass beads, and egg albumin particles were labelled with gamma-emitting isotopes (either 65Zn or 241Am) and fed to the mussels. The beads and albumin particles, of comparable size to the algal species, were used as representative pure mineral and pure protein particles, respectively, enabling a direct comparison of the assimilation of the 2 metals from a common source. Wet weight concentration factors of 65Zn and 241Am in whole mussels ranged from -12 to 35 after 5 d of feeding. 241Am was retained longer than 65Zn by shells, while 65Zn was retained much longer than 241Am in the soft parts. In the soft parts, 241Am was predominantly found in the digestive gland, while 65Zn crossed the gut lining far more effectively than 241Am and was distributed to a greater extent in the gills, muscle, mantle and foot. There was no appreciable influence of food type on the assimilability of the radiotracers, as the mussel tissues distinguished between 65Zn and 2 4 1 ~ m irrespective of food. This was probably a result of the rapid desorption of these radionuclides from the food particles into the acidic gut of the animals, followed by binding of 65Zn to specific ligands or molecules that introduce it into specific metabolic pathways.
Customer Choice Modeling in Hospitality Services: A Review of Past Research and Discussion of Some New Applications

Customer choice modeling techniques have grown in sophistication and applicability, so that this methodology can be useful for assessing the services and amenities that are market drivers for customers of hospitality businesses. In essence, customer choice modeling is an experimental process that seeks to identify the key market drivers by comparing respondents’ choices among packages of products and services, known as choice sets. By comparing the ratings of various choice set packages, one can assess which features of a product or service are most critical to the purchase decision. Also helpful in customer choice modeling is analysis of existing purchase patterns, which can be collected from point-of-sale devices and web activity. However, valuable though it is, collected data are backward looking—telling what customers did, but not what they will do. In contrast, customer choice modeling can look forward to see what customers might like, provided the experiment is designed correctly.
Effects of the 2004 El Niño on tropospheric ozone and water vapor

The global effects of the 2004 El Niño on tropospheric ozone and H2O based on Aura OMI and MLS measurements are analyzed. Although it was a weak El Niño from a historical perspective, it produced significant changes in these parameters in tropical latitudes. Tropospheric ozone increased by 10–20% over most of the western Pacific region and decreased by about the same amount over the eastern Pacific region. H2O in the upper troposphere showed similar changes but with opposite sign. These zonal changes in tropospheric ozone and H2O are caused by the eastward shift in the Walker circulation in the tropical pacific region during El Niño. During the 2004 El Niño, biomass burning did not have a significant effect on the ozone budget in the troposphere, unlike the 1997 El Niño. Zonally averaged tropospheric column ozone did not change significantly either globally or over tropical latitudes.
