While research linking science and aesthetics continues to proliferate, in technical domains like software development, quantitative investigations of aesthetics are virtually nonexistent. As an initial exploration, we administered an online survey to 12 experts and 38 novices in programming, assessing the frequency, nature, time course, and judgment criteria of their aesthetic experience with software code. Both groups reported having aesthetic experiences with code, though somewhat less frequently and intensely than with other creative artifacts. Overall, judgments of "ugly" code were reported to be faster than those of "beautiful" code, which in turn were faster than those of "correct" code. Aesthetic considerations of code were generally rated as quite important, though not as important as functionality. Finally, aesthetic judgment criteria were highly correlated among experts and novices. Results suggest a quantitative approach to aesthetics in software code is a promising direction, with trans-domain implications for aesthetics and creativity.

Many fields of science and engineering rely on running simulations with complex and computationally expensive models to understand the involved processes in the system of interest. Nevertheless, the high cost involved hamper reliable and exhaustive simulations. Very often such codes incorporate heuristics that ironically make them less tractable and transparent. This paper introduces an active learning methodology for adaptively constructing surrogate models, i.e. emulators, of such costly computer codes in a multi-output setting. The proposed technique is sequential and adaptive, and is based on the optimization of a suitable acquisition function. It aims to achieve accurate approximations, model tractability, as well as compact and expressive simulated datasets. In order to achieve this, the proposed Active Multi-Output Gaussian Process Emulator (AMOGAPE) combines the predictive capacity of Gaussian Processes (GPs) with the design of an acquisition function that favors sampling in low density and fluctuating regions of the approximation functions. Comparing different acquisition functions, we illustrate the promising performance of the method for the construction of emulators with toy examples, as well as for a widely used remote sensing transfer code.

A computer code for analyzing the safety feature of triso coated particles for high temperature reactor has been developed based on PANAMA code. This python based code were separated into several modules to perform the main TRIAC-BATAN and linear interpolation calculation, to read the input data file, and to control the sequence of all TRIAC-BATAN calculation. In this initial development phase, TRIAC-BATAN can produce similar pattern as PANAMA calculation in the case of failure fraction of triso particles, either for Depressurized Loss Of Forced Cooling (DLOFC), 100 degrees C higher than DLOFC temperature and constant accident temperature at 1600 degrees C. By using the euclidean distance, TRIAC-BATAN calculation and PANAMA for DLOFC condition are separated in around 3.23.10(-7).

Recent updates in the "Synchrotron Radiation Workshop" physical optics computer code, including the transition to the Open Source development format, the results of the on-going collaborative development efforts in the area of X-ray optics, in particular grazing incidence mirrors, gratings and crystal monochromators, and in other areas, as well as some simulation activities for storage ring and X-ray free-electron laser sources are reported. Future development plans are discussed.

To simulate the intense bunched beam transport, a computer program LEADS-3D has been developed. The particle trajectories are analysed with the Lie algebraic method. The third order approximation of the trajectory solutions is made with space charge forces off, and the second order approximation is made with space charge forces on. The particle distribution in the 3D ellipsoid is uniform or Gaussian. Most of the conventional beam optical elements are incorporated in the code. The optimization procedures are provided to fit the beam lines to satisfy the given optical conditions.

This paper briefly describes the codes used for International Thermonuclear Experimental Reactor (ITER) safety analysis, including some information on their validation status, and summarizes some examples of validation and verification (V&V). V&V information is provided for the codes involved in accident analyses dealing with water coolant ingress into the vacuum vessel. Results obtained by the MELCOR and INTRA codes, and the ISAS system, are compared with the test results of the integrated ICE facility simulating water coolant ingress into the vacuum vessel. Benchmark calculation results of the MELCOR, INTRA, and ISAS were compared with the results from other codes like PAX, CONSEN, TRAC-BF1, CATHARE. (C) 2001 Elsevier Science B.V. All rights reserved.

Dimensionless groups, the output of a successful dimensional analysis, are usually developed via Buckingham's pi theorem. Because this theorem provides a necessary but not sufficient condition for a solution, such a dimensional analysis may, on occasion, appear to fail. The paper presents the necessary and sufficient conditions in a simple form and builds on them to demonstrate how new physical knowledge can augment a 'primitive' set of dimensions to arrive at an optimal number of dimensionless groups. The formulation is used to elucidate the historical Rayleigh-Riabouchinsky controversy and a related thermomechanical problem is analysed to demonstrate the complete 'new knowledge' algorithm. Mathematica code is appended which incorporates these ideas and generates the complete set of admissible dimensionless groups for any specific problem.

Nonlinear finite element analysis was applied to various types of reinforced concrete structures using a new set of constitutive models established in the fixed-angle softened-truss model (FA-STM). A computer code FEAPRC was developed specifically for application to reinforced concrete structures by modifying the general-purpose program FEAR FEAPRC can take care of the four important characteristics of cracked reinforced concrete: (1) the softening effect of concrete in compression, (2) the tension-stiffening effect by concrete in tension, (3) the average (or smeared) stress-strain curve of steel bars embedded in concrete, and (4) the new, rational shear modulus of concrete. The predictions made by FEAPRC are in good agreement with the experimental results of beams, panels, and framed shear walls. (C) 2001 Elsevier Science Ltd. All rights reserved.
