Yayın Controlling electrical appliance by thinking in mind(Maltepe Üniversitesi, 2019) Sharif, Md. Haidar; Uyaver, ŞahinBrain Computer Interface (BCI) technologies open up a world of possibilities. They use signals recorded from the brain (e.g., EEG: Electroencephalography) to apply miscellaneous controls and communications without using any external devices or muscle intervention. Their applications include but not limited to: (i) Brain to device control, (ii) Device to brain control, (iii) Brain to Internet communications with an infinite amount of information storage and retrieval, (iv) Mind to mind communication, (v) Memories and feelings transformation, and (vi) Brain to brain control. However, BCI technologies are still in its emerging stages. This paper demonstrates a brain to device control application for controlling electrical appliances by deeming mind thinking signal of the EEG.Yayın Sentiment analysis of turkish twitter data(Maltepe Üniversitesi, 2019) Shehu, Harisu Abdullahi; Tokat, Sezai; Sharif, Md. Haidar; Uyaver, ŞahinIn this paper, we present a mechanism to predict the sentiment on Turkish tweets by adopting two methods based on polarity lexicon (PL) and artificial intelligence (AI). The method of PL introduces a dictionary of words and matches the words to those in the harvested tweets. The tweets are then classified to be either positive, negative, or neutral based on the result found after matching them to the words in the dictionary. The method of AI uses support vector machine (SVM) and random forest (RF) classifiers to classify the tweets as either positive, negative or neutral. Experimental results show that SVM performs better on stemmed data by achieving an accuracy of 76%, whereas RF performs better on raw data with an accuracy of 88%. The performance of PL method increases continuously from 45% to 57% as data are being modified from a raw data to a stemmed data.Yayın Zayıf/annealed polielektrolitlerin kötü çözücülerde simülasyonu(2008) Uyaver, Şahin; Gümüş, İdris[Abstract Not Available]
