Design and Construction of Infrared Remote Controller for Multiple Home Appliances
Get PDFThe infrared (IR) remote control devices are used to operate in the most of modern household applications, such as television, DVDs, Set top box, Home theatre and air conditioner etc. With the development of the society and smart home, there are more and more home appliances and more infrared remote control devices used to operate them. A single IR remote controller can’t be used to manipulate the different kinds of home appliances; as they are not compatible which leads to the wastage of resources. This paper propose an applications and design of Arduino based IR remote control system, which can control multiple devices, code and decode all of the infrared remote control protocol. In this system, we are using IR based wireless communications for controlling home appliances. Arduino is used for controlling whole the process. The remote control transmits a beam of light using an infrared light emitting diode; this light is picked by the IR sensor. After receiving signal from IR remote, Arduino sends related signal to relays which are responsible for switching ON or OFF of the home appliances through a relay driver. The circuit present in this work is designed to control the six electrical devices such as TV, fan, motor, electric bulb, light tube, and CFL to turn on or turn off from a distance using remote control. The program for this project is written in C language and uploaded into the memory of the microcontroller on Arduino board by Arduino IDE window software
Counter-Terrorism Measures in Selected University Campuses in Nairobi County, Kenya
Get PDFThis study endeavored to assess the security measures put in place in selected university campuses in Nairobi in response to the threat of terror. The study is pegged on the rational choice theory. A total of six University campuses and nine government departments were selected to participate in the study using random and purposive sampling techniques respectively. A total of 69 respondents were purposively selected to participate in the study. The participants were comprised of university campus directors, members of the university security management, members of the campus administration, faculty members, and various categories of student leaders. The study used the mixed-method approach and exploratory research design. Questionnaires, observation checklists, and interview guides were used to collect both qualitative and quantitative data. The Statistical Package for Social Sciences (SPSS) version 24 was used to run descriptive statistics. The inductive approach was utilised since the study accorded prominence to qualitative data. In this regard, data from interviews and open-ended questions were categorized according to the research objectives, inductively analysed, and reported in the form of narration. The responses of the principals, deans, and security personnel show that the security measures that existed in the satellite university campuses were not commensurate with or sufficient to counter the threat of a terror attack because of the many risk and vulnerability factors that were at play in each of the sampled campuses. The paper recommends that there is a need to ensure that disaster management education is standardized and introduced in all universities across the country as a compulsory examinable unit. The hiring practices of security guards for all universities need to be standardized and regulated through enforceable laws and policies. The training of security guards meant to be deployed in universities should be standardized and strictly regulated. Additionally, anyone working in a security management capacity at the university should hold a certain minimum formal education and should have served at a certain level in the disciplined forces and honorably discharged
Improving Impact Strength and Water Absorption Properties of Enset Fiber Reinforced Polyester Composite
Get PDFThis study investigated the utilization of natural Enset fiber which is extracted from a perennial herbaceous plant cultivated in southwestern Ethiopia as reinforcement in Polyester resin matrix for non-load bearing structural elements. The composite samples have been developed by manual hand layup followed by a compression technique. The fiber was treated with a 5wt% NaOH solution (Alkali treatment) for better fiber-matrix adhesion. The fiber percentages (10wt%, 20wt% and 30 wt% by weight) were used for the preparation of the composite. Impact strength and water absorption properties of both raw and alkali-treated fiber-based composite were studied. The result obtained shows that NaOH solution treatment has a positive effect on the impact strength and water absorption properties of the composite. For raw fiber-based composite optimum impact strength was recorded at 20wt% fiber content. However, for treated fiber-based composite highest value was obtained at 30wt% fiber content. For both raw and treated fiber-based composite water absorption is directly proportional to fiber content and it is high for raw fiber-based composit

Comparative Study for Color Image Clustering based on Mahalanobis Distance Method: (Improved fuzzy C- mean clustering method)
No full textColor image has the potential to convey more information than monochrome or gray level images, RGB color model is used in many applications of image processing and image analysis such as Image Segmentation. The standard ways to deal with picture investigation and acknowledgment creatures by division of the picture into areas (articles) and figuring different properties and connections among these districts. Image segmentation algorithms, have been developed for extracting these regions. Important image segmentation is difficult to process due to the inherent noise and deterioration of the input indicators of the algorithm. The regions are not always specified, however, and it is often more fitting to consider them as fuzzy subjects in the image. In this work, an algorithm that is used to segment color images with clustering methods is defined. The lower conditions, results and results are illustrated. In the clustering algorithm, the results are compared using both Mahalanobis and Euclidean distances
4-DOF Robot Arm for Pick and Place Process: Review Article
No full textThe more increase in the number of industries in developing countries, the more laborers or workers are required. To reduce the cost of the labor force and to increase the manufacturing capacity of industries, advanced robot arms are more needed. This paper aims to eliminate the control of the robot arm for picking and placing the object. The arm is constructed in this research with four joints, four links, and four Dc motors to drive the robot arm. Arduino Microcontroller is used to generate the required control signals for DC motors. This paper involves the PID-based kinematic control system which is used for doing successful robotic manipulation tasks in its workspace. Standard DH parameter convention is used to calculate forward kinematics. An analytical method for a closed-formed solution of inverse kinematics is applied to solve the unknown joint angles required for the autonomous position of a robot arm. Four DC motors of four joints are controlled using PID techniques for position control. And for the interface control system via PC, a MATLAB GUI is used to interactively communicate with Arduino controller. The control of this pick and place robot arm system is fully tested in real-time, and the results show that the system has a precise control system for obtaining a good system performance.

Simulation and Modeling of an Integrated Process Route for the Synthesis of Vinyl Chloride Monomer from Acetylene: Factorial Design Method and Artificial Neural Network
Get PDFVinyl Chloride gas is a nonirritating and colorless substance. It is usually colorless at a concentration lower than 3900 ppm (10,000 mg/m3). Vinyl Chloride is simply compressed to liquid for storage and shipping. At a concentration between 200 and 500 mg/m3, a Sweetish odor of Vinyl Chloride may be detected. This research paper is focused on the simulation of an integrated process route for the synthesis of Vinyl chloride Monomer from Acetylene via Aspen Hysys Simulation as well as the Factorial Design of the experiment with MINITAB 17.0. Fit Regression and Artificial Neural Network were employed for the modeling of the responses. Molar flow rates of acetylene (C2H2) and hydrogen chloride (HCl) predicts the conversions of acetylene and hydrogen chloride. A recycle unit is added to the process flow diagram and the maximum conversion of C2H2 and HCl is found to be 99.90 and 99.80 %, respectively. Analysis of variance (ANOVA) gives the results of the statistical correlation between the independent variables and response variables. The simulation and modeling results reveal that the Artificial Neural Network model gives better prediction and analysis of the process route with correlation coefficient (R squared values) of 97.921 % and 98.423 % for the conversion of C2H2 and conversion of HCl, respectively compared to the Factorial Design Method model with R squared values value of 79.47 % and 73.70 % for the conversion of C2H2 and conversion of HCl, respectively
