Parameterized thermal macromodeling for fast and effective design of electronic components and systems

We present a parameterized macromodeling approach to perform fast and effective dynamic thermal simulations of electronic components and systems where key design parameters vary. A decomposition of the frequency-domain data samples of the thermal impedance matrix is proposed to improve the accuracy of the model and reduce the number of the computationally costly thermal simulations needed to build the macromodel. The methodology is successfully applied to analyze the impact of layout variations on the dynamic thermal behavior of a state-of-the-art 8-finger AlGaN/GaN HEMT grown on a SiC substrate

On the use of honesty priming task to mitigate hypothetical bias in choice experiments

We test whether the use of an honesty priming task from the social psychology literature can help mitigate hypothetical bias in stated preference choice experiments (CE). Using a between-sample design, we conducted experiments with five treatments: (1) hypothetical CE without cognitive task, (2) hypothetical CE with cheap talk script, (3) hypothetical CE with neutral priming task, (4) hypothetical CE with honesty priming task, and (5) non-hypothetical CE. Results generally suggest that marginal willingness to pay estimates from treatment 4 where subjects are given honesty priming task before the choice experiment are not statistically different from marginal valuations from treatment 5 where subjects are in a non-hypothetical choice experiment. Values from both these treatments are significantly lower than those from other three hypothetical treatments (treatments 1-3). Using hold out tasks, our results also suggest that one could get higher correct predictions of participants’ choices in treatments 4 and 5 than in treatments 1-3 and that there is no significant difference in percentage of correct predictions between treatments 4 and

Importance of Social Influence in Consumers' Willingness to Pay for Local Food: Are There Gender Differences?

The authors assess consumers' willingness to pay (WTP) for a local food product using an experimental auction. As local foods involve a social component, they aim also to test if social influence affects WTP for local foods and if the effects of social influence on WTP are different between men and women. They found that consumers are willing to pay a premium for the analyzed local food product. Moreover, social influence indeed affects WTP values, but the effects are different between men and women. Although social influence positively affects WTP for local foods for women, the effect is negative for men. The results have significant marketing and policy implications related to the promotion of local foods.Peer Reviewedexperimental auctionlabellamb meatSpainwillingness to payPublishe

Time domain dynamic electrothermal macromodeling for thermally aware integrated system design

Time domain identification of reduced dynamic thermal models is pursued with well established macromodeling techniques, providing electrical equivalents to be integrated in standard circuit simulators. Self and mutual thermal impedances of electronic structures, preliminarily evaluated through accurate 3-D FEM thermal simulations, are directly identified with Time Domain Vector Fitting and synthesised in a lumped PSPICE circuit. Two relevant examples of dynamic electrothermal co-simulation are given, the results of which exhibit significant differences with respect to their isothermal counterpart
