Design of Environment Monitoring System for Intelligent Breeding Base Based on Internet of Things

Xiaojun Zhang, Yan Zhi
With the advent of the intelligent age of electronic information and the continuous improvement of application management, electronic information technology has penetrated into the fields of industry, agriculture, intelligent breeding, and smart home. The aquaculture industry is gradually changing from the traditional method of relying solely on human measurement, control and management to an intelligent, informatized, and automated modern aquaculture method. In order to design an intelligent br...

Investigation of Loss of Consciousness Induced by Gravity Acceleration on the Human Brain

Abbas Shafiee, Amirhossein Ahmadian, Mohammadali Alidoost
Traumatic Brain Injuries (TBI’s) are any disorder in a brain’s functionality that can be caused by numerous reasons, including motor-vehicle crashes, falls, and assaults. Impractical in-vivo head injury experiments compel bio- engineers to develop a robust, accurate, and efficient computer model. In this study, bovine brain samples were tested under a confined compression testing machine. Consequently, the result from unconfined compression tests, at quasi-static strain rates of ε=0.0004...

Web-Based Software for Small Area Estimation under Unit Level Model

James Karangwa, Anshu Bharadwaj
The purpose of this paper is to produce reasonably accurate direct estimators, not only for the characteristics of whole Population but also for a variety of Subpopulations or domains. Many policymakers and researchers also want to obtain statistics for small domains. These small domains are also called small areas, because the sample size in the area or domain from the Survey is small. Due to small sample size, domain-specific direct estimators provide an acceptably large coefficient of variati...

Design and Research of Health Tester System Based on STM32

Zhaoqian Ma, Yan Zhi
In real life, we want to understand our own health status and prevent the risk of disease outbreaks. We need to monitor the physical signs in real time, store and analyze the data, and call the police in time if there is an emergency. According to this requirement, this article designed a multifunctional portable smart health tester based on STM32F407, with Cprtex-M4 32-bit high-performance STM32F407ZGT6 microcontroller as the control core, HP-6 heart rate and blood pressure detection module, LC...

Parallel Self-Timed Adder with Lookahead-Carry Generator

Mohammad Ashfak Habib
Parallel self-timed adder (PASTA) is a newly introduced asynchronous adder. It shows appreciable average-case performance without any special speedup circuitry or look-ahead schema, but its worst-case performance is almost similar to that of ripple carry adder. It is therefore an important research issue to find a technique to improve its worst-case performance without any significant compromise in its other performances. This paper investigates the possibility of such performance improvement of...

Adaptation of Smart Antenna with AODV Routing Protocol for Ad Hoc Wireless Networks

Mebratu Fana Bedasa, Asrat Sime Bedada, Wesenu Bekele Mulatu
In the recent years, Mobile Ad-Hoc Wireless Networks (MANET) have played a key role in communication system. It is a self-configured and infrastructure-less network. It is used in different application areas like disaster recovery operations, hospitals and agricultural sectors. However, there are a lot of problems that limit the performances of this network for significantly achieving its roles in different areas. To overcome these problems, this paper enhances the performances of MANET in wirel...

New Performance Optimization Approach for Cognitive Radio Energy Detection

Patrick Dany Bavoua Kenfack, Fabrice Kwefeu Mbakop, Thomas d’Aquin Biyindi
In this paper, we put forward a new method to deal with energy detection low performance in cognitive radio, especially for small values of signal-to-noise ratio. The method is based on a statistical discrimination of received samples in order to improve probability of detection for a given probability of false alarm. We describe how we have determined discrimination criteria with python pandas library, for a signal-to-noise ratio SNR of 0.5 and a number of samples Ns of 128, assuming Gaussian d...

Design of Library Management System

Chunchao Liu, Sheng Ma
The library management system runs on the DOS system, based on the C lan-guage as the main programming language and Visual C as the development environment. According to the characteristics of the system, we construct the development model and then build structural analysis, system function modules and system flow chart through the demand analysis of the system. Through the analysis of each function module, the definition and at
