Abstract -
This research purpose is to make electronic braille that connected to Android phone. Research and developmental approaches are used for the method. Data processing and controller utilizes Arduino nano microcontroller, Bluetooth module CH05 for Arduino communicate with android mobile application via wireless Bluetooth communication, and mini solenoid are used as the actuator. Android application is used as final interface with voice and touchscreen features. The results are viable and functional braille electronics which connected to android based application as designed. Electronic braille can form braille letter patterns with character change speed that up to 500mS.

Abstract -
One frequently encountered problem in building and applying Geographical Information Systems (GIS) is to find the optimal path (shortest path). Bus route expansion is one demonstration example. The essence of this problem is the implementation of two options. The first is selecting potential locations for bus stop, and the other is choosing one optimal route which go through some potential locations with “lowest cost”. In the past, the problem of finding the optimal path in GIS will be implemented under hard computing. However, geographical data are inherently inaccurate and imprecise. Therefore, a fuzzy logic approach will make the solution to the problem of optimal path becomes more flexible. In this paper, the authors present four steps to expand bus routes in Thai Nguyen city of Vietnam in which using the fuzzy optimal path algorithm. It includes map database collection, map overlay (to identify potential locations), data fuzzification and appling the fuzzy optimal path algorithm.

Abstract -
A major challenge that faces the wide-range deployment of Wireless Sensor Networks (WSNs) is the sensor nodes limited energy supplies. The majority of WSN applications need sensors to have a long lifetime without human intervention and battery replacement. Consequently, energy conservation is one of the basic goals in WSNs. Design approaches to maximize network lifetime like duty cycling, low power, and listening modes have been proposed. In this paper, we explore the energy saving possibilities through in-network analysis patterns. Propose a scheme to perform in-network analytics which increases the lifetime of the network and reduces the random flooding of the messages, thus improving the bandwidth of the entire network.
