Abstract: Recommender system is an encouraging technology for enterprises to present personalized suggestions to their customers. But this technology suffers from sparsity problem. In addition, greatest researches are grounded on explicit rating. But most users do not spend time for rating of products. Therefore, this research proposes an effective recommendation based on user behavior Consumer behavior is one of the most important issues that have been discussed in recent decades. Organizations always want to understand how consumer makes decisions so that they can use it to design their products and services. Having a correct understanding of the consumers and the consumption process has many advantages. These advantages include helping managers make decisions, providing a cognitive basis through consumer analysis, helping legislators and regulators legislate on the purchase and sale of goods and services, and ultimately helping consumers make better decisions. Here is a solution for recommending goods based on the users’ past behavior over deep learning. The architecture expressed for deep learning is trained by users’ past behavioral data. Amazon data was studied and the results indicated that the proposed method has a much higher accuracy than similar methods. Primary contribution is implementation of a user behavior-based recommendation method that discovers interest of users based on implicit rating of product attributes. In addition, this approach uses sequential pattern of purchasing to improve the quality of recommendation.

Abstract: Tungsten and halogen lamps are normally used for microscope illumination. However, if there is an electrical fault in any of these lamps, extra money to purchase a new one and the sacrifice of a long time for its arrival may be required to get the lamp replaced, especially in some developing countries. The aim of this study therefore is to develop a cheap and easily obtainable light source, built with Light Emitting Diodes (LEDs) to replace a faulty tungsten or halogen lamp. The LEDs are cheap to buy, easily available and operate at a much lower voltage. A light source, using LEDs, was designed and constructed to fit easily into the space previously occupied by the tungsten or halogen lamp. An integrated switching low power DC-DC converter, having a microcontroller unit at its heart and powered from a 5 Volt source, was also constructed to control the LED light source. It was observed that the contrast of the sample image obtained with the halogen lamp was reproduced by the LED light source. In this study, a replacement LED based light source for illuminating optical microscopes was constructed, and it gave a reasonable result compared to that obtained by using the halogen lamp. This work will be very useful in those places where it may be very difficult to get a quick replacement halogen or tungsten lamp or where electric power is not always available.
