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 (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...

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...

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...

The greenhouse needs to control environmental parameters to obtain the ideal growth of the plant. The scopes of this paper are to design and im-plement system of real-time remote light intensity, temperature and hu-midity monitoring system for greenhouse based on raspberry Pi3 platforms, which enable the user to monitor acquisition data from the greenhouse. The design system, implemented using LabVIEW as platform software, has to ...

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 ...

The limited lifetime
period of wireless nodes of Ad hoc networks due to their battery power, has
been forming a significant issue and concern for researchers. To solve this
previous related research has ignored low energy nodes regardless of its total
residual energy without ignoring the importance of hop count value for
selecting paths in forwarding decision. This paper aims at finding
and proposing a new path selection metric th ...

Biometric technology as a
means of identifying and verifying an individual’s characteristic is widely
used in many aspects of peoples’ lives nowadays. In this regard, Local
Government Unit (LGU) uses this technology to provide a more comprehensive
system in monitoring employee attendance and how it may affect their
performance. The study assesses the impact of the use about the Biometric Attendance Recor ...

Mobile object detection is
one of the most important steps in computer vision applications such as: medical
analysis human-machine interface, robotics, traffic monitoring, and more. In
this article, we apply the Gaussian mixing model which is established on the
background subtraction. A smoothing method was used for the pre-processing step
and a morphological filter was applied to remove unwanted pixels from the
backgro ...

The study aimed to filter and remove noise from
audio, and in this study researcher followed the descriptive
analytical method. The study sample consisted of an audio file and has been
save Audio of on a formula (WAV), and the study used matlab 7.10.0 to read
sound and design low pass filter, then insert the audio signal with the noise
signal into the filter and output a signal audio without noise. The research ...
