in this paper, the temperature distribution in workpiece and microstructure of welded zone in friction stir welding of aluminum 1100 alloys and the effect of the tool rotational speed on these parameters have investigated experimentally. also feed forward back propagation neural network has been used to predict the temperature of the workpiece during the welding process by considering the proce...

Economic activities of a capitalistic society are organized around the principle of free competition and voluntary trading. In a capitalist society, the right for private properties is divine and the right for political equality for all is regarded as god-given. Political and economical freedom, human dignity and civil rights are commonly promoted. The tremendous power unleashed from liberation...

We propose a formalization of analog algorithms, extending the framework of abstract state machines to continuous-time models of computation. The machine to be described here, like almost every contrivance, apparatus, or machine in practical use, is based very largely upon what has been accomplished by others who previously labored in the same field. —Description of the U.S. Coast and Geodetic ...

Résumé Taking inspiration from neural principles of decision-making is of particular interest to help improve adaptivity of artificial systems. Research at the crossroads of neuroscience and artificial intelligence in the last decade has helped understanding how the brain organizes reinforcement learning (RL) processes (the adaptation of decisions based on feedback from the environment). The cu...

Amendments to laws are necessary to keep up with the changing needs of the society. Such a process is largely manual, and takes feedbacks from the society for the introduction of an amendment. The Right to information (RTI) Act 2005 gives Indian citizens the opportunity to interact with the government. The present paper discusses how analysis of the RTI system can assist in mining feedbacks tha...

Predicting entailment between two given texts is an important task upon which the performance of numerous NLP tasks depend on such as question answering, text summarization, and information extraction. The degree to which two texts are similar has been used extensively as a key feature in much previous work in predicting entailment. However, using similarity scores directly, without proper tran...

Marine invertebrates often have complex life histories that include a swimming planktivorous larval stage, at which time they are vulnerable to a variety of stressors, including those associated with nutritional stress and harmful algal blooms. Lipid stores have been shown to be especially important for post-metamorphic survivorship and growth in a variety of marine invertebrates. We investigat...

Near Infrared spectrometry can be used for measuring the evolution of fruit quality traits. The main characteristics that can be measured are sugar content but also in some case acidity. In conjunction with IFV (institute of Vine and wine), Cemagref research centre and Pellenc SA company have conducted long term researches to get accurate measures of grape sugar and acidity in field conditions,...

Our aim was to compare non-linear and linear mathematical model responses for backstroke start performance prediction. Ten swimmers randomly completed eight 15 m backstroke starts with feet over the wedge, four with hands on the highest horizontal and four on the vertical handgrip. Swimmers were videotaped using a dual media camera set-up, with the starts being performed over an instrumented bl...

Using data from a longitudinal study on Mexican-origin female adolescents, this study examined whether mother-daughter conflict (intensity and frequency) at Wave 1 predicted adolescent depressive symptomatology at Wave 2 and examined the possible mediating role of romantic relationship conflict. A total of 100 participants had complete data on the variables of interest. Results indicated that c...
