A First-Order Logic Formalization of the Industrial Ontology Foundry Signature Using Basic Formal Ontology

Basic Formal Ontology (BFO) is a top-level ontology used in hundreds of active projects in scientific and other domains. BFO has been selected to serve as top-level ontology in the Industrial Ontologies Foundry (IOF), an initiative to create a suite of ontologies to support digital manufacturing on the part of representatives from a number of branches of the advanced manufacturing industries. We here present a first draft set of axioms and definitions of an IOF upper ontology descending from BFO. The axiomatization is designed to capture the meanings of terms commonly used in manufacturing and is designed to serve as starting point for the construction of the IOF ontology suite

A Project-based Learning Approach in Teaching Simulation to Undergraduate and Graduate Students

In this study, application of experiential learning into graduate and undergraduate curricula of a industrial system simulation course is presented. Simulation has been among the courses against which students feel uncomfortable or frightened due to heavy software use, prerequisite of probability, and statistics knowledge, and its application requirements. To minimize this fear and improve student’s understanding about the subject matters and have them develop ample skills to build complex models, a project-based learning approach is proposed and used in undergraduate and graduate teaching settings. To achieve the project-based learning goals, a 15-week curriculum is designed to have a balanced lecture and lab sessions, which are specifically designed to address the needs of the term project as the semester continues. In the term project, groups of 2-3 students were asked to form a group, where each group was expected to work on a real system to 1) understand, conceptualize, and model the existing system as a mental, then software-model; 2) validate the existing system model statistically; 3) identify areas for improvement (in addition to the ones given by the supervisor); 4) complete the project with testing out system improvement scenarios and conducting cost/benefit analysis. The effectiveness of project-based learning is surveyed and studied based on the course learning outcomes. The results indicated that the proposed project-based learning approach was found to be effective in students’ learning experience and critically supportive on reaching the learning outcomes, and it was found that students’ learning and skills of simulation modeling and application are improved regardless of their grade

GASTRONOMY TOURISM POTENTIAL OF TURKEY

As a rapidly growing industry, tourism has become, in recent years, an important sector considered attractive to financiers due to the changes tourism has caused in countries’ economic and sociocultural structures and this industry’s positive contributions to national economies and policies. As one of many subtypes of tourism, gastronomic tourism has developed into a strong attractor thanks to gastronomic activities in tourist destinations. As in many countries around the world, Turkey now provides domestic and foreign tourists with chances to participate in activities organized by public and private organizations that seek to generate business in gastronomic tourism. In this context, this study seek to investigate the importance and current status of gastronomic tourism in Turkey and to identify activities organized as part of the development of gastronomic tourism.  </p

The Role of Physical Image Properties in Facial Expression and Identity Perception

A number of attempts have been made to understand which physical image properties are important for the perception of different facial characteristics. These physical image properties have been broadly split in to two categories; namely facial shape and facial surface. Current accounts of face processing suggest that whilst judgements of facial identity rely approximately equally on facial shape and surface properties, judgements of facial expression are heavily shape dependent. This thesis presents behavioural experiments and fMRI experiments employing multi voxel pattern analysis (MVPA) to investigate the extent to which facial shape and surface properties underpin identity and expression perception and how these image properties are represented neurally. The first empirical chapter presents experiments showing that facial expressions are categorised approximately equally well when either facial shape or surface is the varying image cue. The second empirical chapter shows that neural patterns of response to facial expressions in the Occipital Face Area (OFA) and Superior Temporal Sulcus (STS) are reflected by patterns of perceptual similarity of the different expressions, in turn these patterns of perceptual similarity can be predicted by both facial shape and surface properties. The third empirical chapter demonstrates that distinct patterns of neural response can be found to shape based but not surface based cues to facial identity in the OFA and Fusiform Face Area (FFA). The final experimental chapter in this thesis demonstrates that the newly discovered contrast chimera effect is heavily dependent on the eye region and holistic face representations conveying facial identity. Taken together, these findings show the importance of facial surface as well as facial shape in expression perception. For facial identity both facial shape and surface cues are important for the contrast chimera effect although there are more consistent identity based neural response patterns to facial shape in face responsive brain regions

The use of principal component analysis for reduction of training load data in professional soccer

The aim of this study was to explore the use of principal component analysis (PCA) in understanding multivariate relationships in soccer training load data. Training load data were collected from 20 professional male soccer players during a 28-week in-season period. Twelve training load variables (total distance, PlayerLoadTM, low-speed running distance, moderate-speed running distance, high-speed running distance, sprint distance, moderate-speed running efforts, high-speed running efforts, sprint efforts, accelerations, decelerations, and changes of direction) were collected during training sessions, with correlation analysis revealing high intercorrelation between most variables (r = 0.04-0.98). Principal component analysis was performed on datasets containing all players and on individual players. On the whole dataset, two principal components were retained explaining a total of 81% of data variance. The first component comprised variables associated with distances in speed zones and the second component changes of direction. Whilst some individual variation existed among players, distances in speed zones were loaded on the first component and inertial movement analysis variables, such as accelerations, decelerations, and changes of direction, were loaded on the second component. These findings evidence the strong relationships between several common training load variables and highlight the risk of data redundancy. By selecting variables from each component, practitioners can reduce the number of variables reported whilst retaining as much of the variation in data as possible

Effect of Scan Strategies and Use of Support Structures on Surface Quality and Hardness of L-PBF AlSi10Mg Parts

Additive manufacturing allows for a great degree of design freedom and is rapidly becoming a mainstream manufacturing process. However, as in all manufacturing processes, it has its limitations and specificities. Equipping engineers with this knowledge allows for a higher degree of optimization, extracting the most out of this technology. Therefore, a specific part design was devised and created via L-PBF (Laser Powder Bed Fusion) using AlSi10Mg powder. Certain parameters were varied to identify the influence on material density, hardness, roughness, residual stress and microstructures. It was found that on heat treated parts laser pattern strategy is one of the most influential aspects, showing that chessboard and stripes 67° improved outcome; average Ra roughness varied between 8–12 µm, residual stress was higher on vertical surfaces than horizontal surfaces, with the combination of support structures and stripes 67° strategies generating the lowest residual stress (205 MPa on a lateral/vertical face), hardness was non-orientation dependent and larger on samples with chessboard fabrication strategies, while microstructures were composed of α–Al dendrites surrounded by Si particles. The distribution and grain size of the microstructure is dependent on location regarding melt pool and HAZ area. Furthermore, Al–Mg oxides were encountered on the surface, along with pores generating from lack of fusion.The authors would like to acknowledge the Hypermetal Additive Manufacturing for their contribution with some additive manufactured samples and materials, as well as ONA Electro-Erosión Lda. for the use of their electro erosion cutting equipment, used for the separation of certain samples from the build plate.

Knowing what from where : Hippocampal connectivity with temporoparietal cortex at rest is linked to individual differences in semantic and topographic memory

The hippocampus contributes to episodic, spatial and semantic aspects of memory, yet individual differences within and between these functions are not well-understood. In 136 healthy individuals, we investigated whether these differences reflect variation in the strength of connections between functionally-specialised segments of the hippocampus and diverse cortical regions that participate in different aspects of memory. Better topographical memory was associated with stronger connectivity between lingual gyrus and left anterior, rather than posterior, hippocampus. Better semantic memory was associated with increased connectivity between the cuneus/precuneus and left, rather than right, posterior hippocampus. Notably, we observed a double dissociation between semantic and topographical memory: better semantic memory was associated with stronger connectivity between left temporoparietal cortex and left anterior hippocampus, while better topographic memory was linked to stronger connectivity with right anterior hippocampus. Together these data support a division-of-labour account of hippocampal functioning: at the population level, differences in connectivity across the hippocampus reflect functional specialisation for different facets of memory, while variation in these connectivity patterns across individuals is associated with differences in the capacity to retrieve different types of information. In particular, within-hemisphere connectivity between hippocampus and left temporoparietal cortex supports conceptual processing at the expense of spatial ability
