Prediction of Individual Non-Linear Aging Trajectories of Faces

Represented in a Morphable Model, 3D faces follow curved trajectories in face space as they age. We present a novel algorithm that computes the individual aging trajectories for given faces, based on a non-linear function that assigns an age to each face vector. This function is learned from a database of 3D scans of teenagers and adults using support vector regression. To apply the aging prediction to images of faces, we reconstruct a 3D model from the input image, apply the aging transformation on both shape and texture, and then render the face back into the same image or into images of other individuals at the appropriate ages, for example images of older children. Among other applications, our system can help to find missing children.     

Fast Image‐Based Modeling of Astronomical Nebulae

Astronomical nebulae are among the most complex and visually appealing phenomena known outside the bounds of the Solar System. However, our fixed vantage point on Earth limits us to a single known view of these objects, and their intricate volumetric structure cannot be recovered directly. Recent approaches to reconstructing a volumetric 3D model use the approximate symmetry inherent to many nebulae, but require several hours of computation time on large multi‐GPU clusters. We present a novel reconstruction algorithm based on group sparsity that reaches or even exceeds the quality of prior results while taking only a fraction of the time on a conventional desktop PC, thereby enabling end users in planetariums or educational facilities to produce high‐quality content without expensive hardware or manual modeling. In principle, our approach can be generalized to other transparent phenomena with arbitrary types of user‐specified symmetries.

The effects of instructional support and learner interests when learning using computer simulations

Within the scope of this study, the effectiveness of two kinds of instructional support was evaluated with regard to the learner’s interests. Two versions of a simulation program about the respiratory chain were developed, differing only in the kind of tasks provided for instructional support: One version contained problem-solving tasks, the other one contained worked-out examples. The focus was on the learner’s interest in the subject and in computers. The first goal of the study was to find to what extent computer simulations incorporating the different kinds of instructional support have positive effects on situational subject-interest. The second goal was to evaluate the interactions between the learner’s interests and the instructional support with regard to the learning results (subdivided into factual knowledge and understanding). Simulations with worked-out examples were shown to have positive effects on the learner’s situational interest in the subject. This was not found to be the case in simulations with problem-solving tasks. Regardless of the kind of instructional support, learners with little interest in the subject were able to achieve significant gains in factual knowledge. However, improvement in understanding was dependent on the kind of instructional support.     

Award for Distinguished Scientific Applications of Psychology.

The Award for Distinguished Scientific Applications of Psychology is presented to persons who, in the opinion of the Committee on Scientific Awards, have made distinguished theoretical or empirical advances leading to the understanding or amelioration of important practical problems. This document lists the winners of this award from 1973 to 2001, and provides the citation, biography, and selected bibliography for the 2001 recipient, David T. Lykken. Lykken's award address, entitled "Parental Licensure," is also included. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Distinguished Scientific Award for the Applications of Psychology 1986: Martin T. Orne.

Martin T. Orne, the 1986 recipient of the Distinguished Scientific Award for the Applications of Psychology, was presented with a check for $2,000 and an engrossed citation of his contribution. Orne receives this award "for his efforts to integrate psychological theory and methods with the pragmatic concerns of psychotherapy, medicine, and law. Through his research he has helped practitioners to realize the potential benefits and limitations of hypnosis, lie detection, sleep, and biofeedback, and the roles played by specific and nonspecific factors in psychotherapy and behavioral medicine. His analysis of the social context of the experiment has elucidated the importance of demand characteristics in shaping experience and behavior, and helped alter the way in which both experimentalists and clinicians evaluate the reactions of subjects, clients, and patients. Psychologist, physician, scientist, clinician, editor, and expert witness, no one better exemplifies the theoretical and practical advantages of transcending disciplinary boundaries in the pursuit of our common goals."

Titanium in Automotive Production

Although titanium has meanwhile made its way into serial production of automotive parts, its use has been widely limited to niche applications and was not driven by weighing the technical and economic aspects. Cost of semi‐finished titanium products is still limiting; indeed, new and cheaper processes for production of Ti itself are urgently needed. However, if one extrapolates the current status of Ti technology based on the historic development of the knowledge bases on other automotive metals (steel, Al, and Mg), the future of titanium use in cars looks quite bright.
