The communication between humans and chatbots have been a topic of interest for a long time in the research community. But the aim of my research is to analyze the emotional intelligence of chatbots when they are engage in communication with humans. Since chatbots are known to give monotonous response for a specific question asked by the users thus, it has a uniform answers to all users irrespective of  difference in the questions. So, by utilizing NLP (Natural Language Processing), we can train these chat bots with dynamic datasets containing emotional words commonly used by humans when they use their emotional appeal in achieving results during conversation. Chat bots will be able to understand emotional conversations with humans.

A distributed sensor network has been programmed to simulate synchronized calling exhibited by many species of frogs and insects. The distributed sensor network consists of numerous sensor nodes consisting of a microprocessor, wireless communications and a sensor board containing a buzzer and microphone. The goal was to program the sensor array to mimic the synchronized calling behavior (inspired in no small part by the recent appearance of cicada brood X). To this end, a single leader node was programmed to begin calling (i.e., buzzing). The remainder of the node array was programmed with an algorithm which allows them to detect other buzzing nodes and to synchronize their own buzz to that of the group. After start-up transients, the entire array calls in synchrony. Of particular interest is the system’s transient behavior system when perturbed or when a second leader node begins calling out of synch with the array. The hardware and software algorithms will be described. Furthermor...

The Methods Utilizing the Phenomena of Light Scattering to Measure Particle Size distribution in different solvent, such as deionise water and alcohol and also to study the various structural formation when nanodiamond solution is placed on silicon surface.
The purpose of this research project is divided into two parts
1. to configure the measurement units for examining modified nanodiamond particles, examination of their sizes when placed in different solvents and observing the zeta potential of the particles when placed in different solvents.
2. to observe the structural formation for different nanodiamond particles droplets on silicon glass.
The particle size distribution will be measured using dynamic light scattering techniques
using derived solutions made from either deionized water or alcohol. The particle charges will be determined using the zeta potential.
The structural formation drawn by droplets of nanodiamond particles will be observed using a biological microscope.

A solar security lighting system has been designed, constructed and installed in the Faculty of Engineering and Technology, Ambrose Alli University, Ekpoma. The system incorporates twenty four (24) solar panels each rated 130watts/17vdc connected in series of two and parallel of twelve(12), Ten(10) batteries rated at 200AH connected in series of two(2) to obtain 24volts and also connected in parallel of five(5).AC-DC converter and automatic switching mechanism are incorporated in the system. There are ten (10) poles mounted on concrete bases each having two led fittings with thirty six (36) LED each to illuminate the dark areas of the Faculty during the night. The system is such that it automatically switches on between 6.30pm to 6.30am without human intervention. From test carried out on hourly basis, the battery voltages remain constant from 24volts to 21.5volts, which quite adequate to power the LEDs. The charging current delivered by the controller to charge the batteries during the peak period from 1pm to 3pm is 45.14amps. It was also observed that during rainy day it‟s measures between 6 to 15amps. The incorporation of AC-DC converter enable the charging of the batteries and also to power the load when utility supply(BEDC) is available at night to maintain the voltage level of the battery, so that during the absence of BEDC, the batteries have sufficient energy to work efficiently without much loss and to increase the life span of the batteries. The project have proved to be efficient, reliable and security effective in the Engineering Faculty of Ambrose Alli University Ekpoma, Edo state.
