Engineering goals are typically rooted in addressing the functional needs of a product. While these engineering goals and specifications can be important in consumers’ buying decisions, many times the first impression of the product comes from judgments of the product’s aesthetic form. For this reason, this paper set out to study how well human judgment of performance based on a car’s shape correlates with the actual measured performance of the car’s shape, and what features of the car’s shape most influence this judgment. More specifically, participants were asked to rate how aerodynamic, sporty, fuel efficient, and rugged a computer generated car design appeared to them, and these ratings were analyzed against the actual aerodynamics of the vehicle as well as key indicators of sportiness and cornering stability such as center of gravity and wheel stance. The inter-rater consistency of human judgments was also studied. Using this human judgment data, the attributes in car design with the greatest effect on participant judgment of vehicle performance were identified, and were compared against their importance and effect in actual vehicle performance. Analysis of this data gives key insights about how car designers can create designs that better convey the desired goals of a car to consumers while also meeting those performance goals.

Engineering goals are typically rooted in addressing the functional needs of a product. While these engineering goals and specifications can be important in consumers' buying decisions, many times the first impression of the product comes from judgments of the product's aesthetic form. For this reason, this paper set out to study how well human judgment of performance based on a car's shape correlates with the actual measured performance of the car's shape, and what features of the car's shape most influence this judgment.

Analysis of this data gives key insights about how car designers can create designs that better convey the desired goals of a car to consumers while also meeting those performance goals. The results of this study provide evidence that consumers are reasonably accurate at determining certain functional performance traits, such as aerodynamics, but are insensitive to other traits, such as the wheelbase of the vehicle design. It was also determined that the stylistic and functional performance judgments of the consumers surveyed may have been influenced by social norms and conventions learned from past experiences with vehicle designs.

The Aesthetic

This is a report of research findings regarding the lore of traditional clothing/costume in Bali Aga village in terms of its form, function, and meaning, along with its transformation in dance creativity. This is recently developed in the villages of Tenganan Pegringsingan and Asak Karangasem, where the art is inherited from one generation to another generation. The developed form of clothing in the traditional village of Bali Aga is distinctively unique, i.e. the featuring form is stimulated by the mutual support between the function and the meaning. In addition to featuring the aesthetic form, the clothing lore also reflects the meaning. This is possible due to the fact that the selected form does not only cater to the aesthetic deliberation, but he content reflects worthy and interesting symbolic values.

Key Indicators

In this paper IPA (importance–performance analysis) is used to assess location attractiveness for investments as a competitiveness factor in Serbian tourism. Based on the theory of Dunning’s eclectic paradigm, regarding locational advantages as a factor for investments, twelve key indicators were selected for assessment by stakeholders in the private and public sectors. The conclusion derived from the analysis implies that Serbia is under performing in relation to the importance of the selected indicators. The largest proportion of indicators is classified as the ‘concentrate here’ strategy type in the IPA matrix. The conclusions regarding the importance and performance of indicators allocated to other quadrants (especially ‘low priority’ and ‘possible overkill’) are also significant. This paper establishes the bases for analysis that can help both the public and the private sector to develop strategies for the development of tourism and the competitiveness of Serbia as a tourist destination, referring to investments (locational advantages) as a competitiveness factor.

Abstract This paper reviews design and analysis methods applied in developing a three-piece Coulomb-damped truck arrangement to meet the requirements of specification M-965. This section of the AAR standards specifies performance criteria for high center of gravity cars over twist and roll inputs. The test input is a track section with a series of staggered low joints. These act to excite car body roll. The review demonstrates that properly designed suspension and damping components, in combination with side bearings, will achieve the required performance through the life of the truck. It also demonstrates the effectiveness of accurate vehicle dynamics simulations as a conservative predictor of actual vehicle performance on perturbed track. The design and analysis methods are described in detail. Guidelines are provided to help determine appropriate suspension arrangements for high CG car applications.

Biomechanical Factors

AbstractThe aim of this study was to identify biomechanical factors affecting successful and unsuccessful snatch attempts in elite female weightlifters during the 2013 World Weightlifting Championships. Fourteen female competitors took part in this study. Their successful and unsuccessful snatch lifts with the same load were recorded with 2 camcorders (50 Hz), and selected points were digitized manually on to the body and the barbell using the Ariel Performance Analysis System. The kinetic and kinematic barbell movement as well as the athlete’s body movement variables during the liftoff phase were examined. The results of this study show statistical differences (p ≤ 0.05) between successful and unsuccessful attempts in relation to the angle values in the knee and hip joints in preparation for the aerial phase position. Similarly, the center of gravity velocity was significantly higher in successful attempts during the catch phase. Thus, coaches should pay particular attention to the accuracy of the execution in preparation for the aerial phase position and to the velocity of the center of gravity of the competitors during the catch phase.
