Brute Force is not Ignorance
Chaitin’s notion of program elegance, that is of the smallest program to satisfy some specification, does not explicitly take account of the balance between a formal notation’s expressive power and the richness of its semantics. To explore this wider space of elegance, we are investigating realisations of the Busy Beaver game (BBG) which involves finding programs of given size that produce maxi...

تجزیه و تحلیل گیت (gait analysis)عبارت است از تحقیق روی راه رفتن از نظر حرکت اندامها می باشد، در این بررسی می توان مواردی نظیر کنترل موقعیت، سینتیک و سینماتیک بدن ، کنترل بدن و کنترل عصبی را در نظر داشت. اینگونه تحقیقات در ارتوپدی ، بیومکانیک ورزش و عصب شناسی و کاربرد دارند. پارامترهای مهم در اینگونه تحقیقات عبارت از نیرو ، ممان ، سرعت ، مصرف انرژی و فشار کف پا می باشند. سه روش برای اندازه ...
15 صفحه اولWhen working is not enough: food insecurity in the Canadian labour force.
OBJECTIVE Food insecurity, lack of access to food due to financial constraints, is highly associated with poor health outcomes. Households dependent on social assistance are at increased risk of experiencing food insecurity, but food insecurity has also been reported in households reporting their main source of income from employment/wages (working households). The objective of the present stud...
متن کاملModeling and analysis of a three-component piezoelectric force sensor
This paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. The cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. Hamilton's principle is used to derive...
متن کاملFORCE-DIRECTION DISCRIMINATION IS NOT INFLUENCED BY REFERENCE FORCE DIRECTION (Short Paper)
The authors report an experiment in which twenty-five participants discriminated force vectors presented along five directions (up, left, right, diagonally up left, diagonally up right). The force vectors were presented with a three degree-of-freedom forcefeedback device. A three-interval one-up three-down adaptive procedure was used. The five reference force-direction conditions were presented...
