Monte Carlo software MCNP and Geant4 were used to study the factors affecting the detection efficiency of the lanthanum bromide detector, mainly including the thickness of the detector al shell and the size of the crystal. The results of the two softwares were compared. The results show that only the thickness of the front Al shell increases the detection efficiency of the full energy peak, and the side al shell has little effect on the detection efficiency of the full energy peak; The increase ...

Protein is a class of food needed daily by humans and even animals. Protein is rated as 20% to 30% of daily food requirements making it a very significant part of daily needs in compliance with the International Labour Organization (ILO) order on food. This class of food from animals has been threatened and carries a lot of health risks unlike protein from plant sources. The need for an alternative to plant protein led to this work. A neuro-fuzzy expert system for detection of leghemoglobin in l...

A wireless communication system for cellular technology is currently considered a very important topic for mobile phone. The design of such systems needs to include their multipath and fading main problems. In this paper, a MIMO-OFDM channel is designed and modeled to combat such problems, as well as STBS and directivity are also involved in this design to increase system reliability and enhance BER performance. The modeling and simulation process of the designed systems are carried out using Ma...

This paper presents the performance analysis of Bluetooth Low Energy (BLE) IEEE 802.15.1 standard in the piconet topology networks. The performance of the BLE network is analyzed in terms of connection interval (CI) and the number of slaves (NS) by using OMNET (v4.6) simulator. In the performance investigation process Data Length Extension (DLE) features is used with an application payload size of 60 bytes in order to achieve the best performance in a BLE (P2P) network. The modeled networks an...

In this paper, a modified SIS (susceptible-infected-susceptible) model with infective medium
and feedback mechanism on scale-free networks is presented. The model is suited to describe some epidemic spreading which are not only transmitting by
medium but also spreading between individuals by direct contacts. Considering
biological relevance and people’s subjecti ...

The whole globe is covered universally by water with a majority space. In
view of extraction of minerals as well as national security reasons, underwater
communication has become quite important for all the mankind. Researchers,
around the world are working for optimizing the multiple scheme in acoustic
channel. Recently, the researchers have reported valuable employability of IDMA
scheme in acoustic communica ...

In this paper electronic feed forward
equalization is performed to mitigate the link chromatic dispersion. The
equalizer coefficients are computed by a decision-directed process based on the
sign-sign least mean square and the recursive least square algorithm.
Therefore, this paper evaluates the performance of these algorithms in
chromatic dispersion compensation at bit rate of 10 Gb/s. This paper compares
these two adaptation algorithms for receiver based on analogue elec ...
