Abstract

As the world is moving further into the core of digital technology, the requirements of computational devices are growing rapidly that are small in size and consume bare minimum energy. Wireless Sensor Networks (WSNs) belong to this category that form a pervasive set of computational devices, deployed in environment for sensing and monitoring physical phenomenon. Sensor nodes find plenty of applications in industries where we need to continuously monitor parameters such as humidity, temperature etc. They are deployed for lengthy periods in environment, mostly at inaccessible places. As WSNs are deployed in a form of a huge network, it Continue reading...

A robotic arm is a kind of mechanical arm, mostly programmable; that mimics the functions of a human arm. The close emulation of a human hand is desired in robotic arms because it increases the number of applications for which it can be used. A typical arm consists of 3-7 metal segments connected by 3-6 joints. A computer controls the robotic arm by rotating the servo motors linked to each joint. The robotic arm also uses sensors to control the movement of the parts to the required extent. Sensors are used to determine the system’s current state. Robotic Continue reading...

Introduction

The extreme limitations and demand for the installation setting of wireless communication network for sensor enables safety of wireless systems extra difficult as compared to traditional networks. Nevertheless, a number of features portrayed by networks for sensors can assist in tackling the difficulties of setting up protected networks. The exceptional features of this type of network might possibly permit fresh defenses that do not exist within the traditional networks. A network for wireless sensors consists of several minute and low-priced sensor nodes having many different features. It has extremely less power for processing alongside radio ranges, allowing extremely low Continue reading...

Intelligent door controlled by Raspberry pi

Abstract
This paper proposes the use of an embedded system - Rasperry Pi to develop smart home software. The system utilizes the recent phenomenon in computing referred as Internet of Things. The objective of the phenomenon is to extend the positives of regular internet in terms of connected every device in the home environment to create a smart network. A proposed intelligent door control management system is presented. The intelligent system uses 512 MB RAM Raspberry Pi microcontrollers with a Broadcom BCM2835 system chip, a passive infrared sensor and a Wi-Fi dongle and a door bell. The system is Continue reading...

The re a number of technologies that are associated with network security defense. Firstly are those technologies that supports wireless sensor network where many features of sensor networks might aid in tackling the challenge of building network that is secure. The unique feature of sensor network might permit fresh defenses that do not actually exist in conventional network. Some of the wireless technologies for network security defense include SPINS, TINYSEC, and LEAP (Singh, Singh & Singh, 2011).
The security protocol for sensor network (SPINS) is a security building block that is optimized for resource limited environments and communication using wireless Continue reading...

Advances in technology should be used to improve patient care. In acute and chronic illness, biomedical monitoring of indicators such as pulmonary artery pressure in COPD, right ventricle pressure in right-sided heart failure, and pressure in an aneurysm sac can aid clinicians in detecting real-time changes that require modifications in the treatment plan where doing so ensures optimum patient outcomes. One recent technology is the monitor integrated with medical stent (MIMS) that permits the continuous measurement of pressure in the heart and blood vessels. Knowing what the technology is, its indications and contraindications, its application, and the expected outcomes Continue reading...

The following method chosen for the study is large-scale study with various lung cancer patients. The low cost of the electronic nose unit used in this study allowed gave us freedom to do a larger clinical trial to detect lung cancer in patients. Within this study we cooperated with a number of fields including: nanotechnology, biomedical designs & engineering, medical oncology as well as computational approaches. This multilevel approach allowed us to design a very sensitive, low cost, non-invasive nanometric electronic nose (e-nose) that has a very quick response time. Similar approaches were done in previous studies (Li et al, Continue reading...

Problem Statement

This is a proposal to design an automatic door opener prototype. The door will be controlled by an IR sensor circuit programmed with open and close door functions. The automatic door opener will be connected to a power supply which will operate the door opening and closing mechanism. The operation principle of the door opener is that it will sense an oncoming object such as a human; it will then open the door wide enough for the objet to go through the door. The door will remain open until there is no object within the door opener’s operation Continue reading...
