Emotion Analysis on EEG Signal Using Machine Learning and Neural Network

Emotion has a significant influence on how one thinks and interacts with others. It serves as a link between how a person feels and the actions one takes, or it could be said that it influences one's life decisions on occasion. Since the patterns of emotions and their reflections vary from person to person, their inquiry must be based on approaches that are effective over a wide range of population regions. To extract features and enhance accuracy, emotion recognition using brain waves or EEG signals requires the implementation of efficient signal processing techniques. Various approaches to human-machine interaction technologies have been ongoing for a long time, and in recent years, researchers have had great success in automatically understanding emotion using brain signals. In our research, several emotional states were classified and tested on EEG signals collected from a well-known publicly available dataset, the DEAP Dataset, using SVM (Support Vector Machine), KNN (K-Nearest Neighbor), and an advanced neural network model, RNN (Recurrent Neural Network), trained with LSTM (Long Short Term Memory). The main purpose of this study is to improve ways to improve emotion recognition performance using brain signals. Emotions, on the other hand, can change with time. As a result, the changes in emotion over time are also examined in our research

Forecasting the Quantity of Shrimp and Dry Fish Export from Bangladesh

This study presents forecasting quantity of shrimp and dry fish export from Bangladesh for five years by using deterministic models that could be used to make efficient forecast of shrimp and dry fishes. These models are very much quick, inexpensive and capable of describing time series data adequately in many situations. In this study, nine different deterministic time series models have been considered. They are all fitted to data of shrimp & dry fish exports from Bangladesh. Among the deterministic type models, the cubic model is best for shrimp export and S-shaped model is more applicable for dry fish export. From this study, it has been found that the increase of shrimp export would be 4.93% annually or 24.67% over coming five years. The total amount would increase from 57017.56 thousand tones to 71081.6 thousand tones during 2010/11 to 2015/16. It has been observed that the quantity of dry fish export would increase by 0.46% annually. The total amount would increase by 2.30% i.e., from 355.30 thousand tones to 363.30 thousand tones during 2010/11 to 2015/16. Keywords: Forecast, Shrimp export, Dry fish export

Analysis of Marketing Efficiency and Spatial Co-Integration of Rohu (Labeo Rohita) Fish in Some Selected Areas of Bangladesh

The study was undertaken to examine the value chain, value addition, marketing cost & margin, marketing efficiency and market integration of rohu fish in selected areas of Bangladesh during the month of July-August 2012. The objectives of the study were to estimate costs and margins, seasonal price variation and to test market integration of rohu fish. Primary and secondary data were used for this study. The higher marketing cost was incurred by paiker and the lowest by retailer. On the other hand, retailers earned the highest net marketing margins. Chain II was found the most efficient chain. Analysis of market integration shows that rohu fish market in Bangladesh was well integrated. The findings of the study revealed that the marketing of rohu fish was a profitable business and some recommendations were provided for the improvement of rohu fish marketing in the country. Keywords: Value addition, marketing cost & margin, marketing efficiency and spatial co-integratio

Pengembangan Metode Daur Ulang Limbah Silika Fase Diam Kromatografi Untuk Kegiatan Praktikum Di Laboratorium

Silika merupakan salah satu limbah laboratorium yang dapat merusak lingkungan. Daur ulang limbah silika mampu meminimalisasi jumlah limbah di laboratorium. Proses daur ulang limbah silika gel terdiri dari empat tahapan yaitu pencucian dengan metanol dan aseton secara maserasi, proses sonikasi dengan gelombang ultrasonik, pemanasan dengan tanur pada suhu 600oC selama 8 jam dan karakterisasi dengan radiasi sinar UV dan FTIR. Hasil karakterisasi dengan radiasi sinar UV pada berbagai perlakuan daur ulang limbah silika gel dapat membuktikan bahwa lama dan jumlah ulangan pencucian berpengaruh terhadap tingkat keberhasilan daur ulang limbah silika. Hal tersebut dapat diindikasikan dengan noda atau area hitam yang semakin memudar. Perlakuan proses daur ulang terbaik berdasarkan karakterisasi dengan lampu UV dilanjutkan proses karakterisasinya dengan FTIR. Berdasarkan hasil karakterisasi dengan radiasi sinar UV dan FTIR perlakuan terbaik untuk proses daur ulang limbah silika gel pada penelitian ini adalah pada perlakuan dengan proses tiga kali pencucian metanol dan aseton dalam waktu 6 jam dalam setiap tahap pencucian.  Silica is a laboratory waste that can damage the environment. The recycling of silica waste can minimize the amount of waste in the laboratory. The recycling process of silica gel waste consists of four stages, namely washing with methanol and acetone by maceration, sonication process with ultrasonic waves, heating with a furnace at a temperature of 600°C for 8 hours and characterization with UV and FTIR radiation. The results of characterization with UV radiation in various recycling treatments of silica gel waste can prove that the duration and number of washing repetitions have an effect on the success rate of recycling silica waste. This can be indicated by blemishes or black areas that are getting faded. The best recycling process based on characterization with UV lamps followed by the characterization process with FTIR. Based on the characterization results with UV radiation and FTIR, the best treatment for the recycling process of silica gel waste in this study is the treatment with a three time process of washing methanol and acetone within 6 hours in each washing stage

Study of wear resistance and nanostructure of tertiary Al2O3/Y2O3/CNT pulsed electrodeposited Ni-based nanocomposite

Electrodeposition of tertiary Alumina/Yitria/carbon nanotube (Al2O3/Y2O3/CNT) nanocomposite by using pulsed current has been studied. Coating process has been performed in nickel sulphate bath and nanostructure of the obtained compound layer was examined with high precision figure analysis of SEM nanographs. The effects of process variables, i.e. Y2O3 concentration, treatment time, current density and temperature of electrolyte have been experimentally studied. Statistical methods were used to achieve the minimum wear rate and average size of nanoparticles. Finally the contribution percentage of different effective factors was revealed and confirmation run showed the validity of the obtained results. Also it has been revealed that by changing the size of nanoparticles, wear properties of coatings will change significantly. Atomic force microscopy (AFM) and transmission electron microscope (TEM) analysis have confirmed smooth surface and average size of nanoparticles in the optimal coating.Вивчено електроосадження методом імпульсного струму потрійного композиту на основі вуглецевих нанотрубок, алюмінію та ітрію оксидів.
