This paper presents GSM speech coder indirect identification algorithm based on sending novel identification pilot signals through the GSM speech channel. Each GSM subsystem disturbs identification pilot, while speech coder uniquely changes the tempo-spectral characteristics of the proposed pilot signal. Speech coder identification algorithm identifies speech coder with the usage of robust line...

Male genital self-mutilation (GSM) is a rare but serious phenomenon. Some of the risk factors for this act are the presence of religious delusions, command hallucinations, low self-esteem, and feelings of guilt associated with sexual offences. Other risk factors include failures in the male role, problems in the early developmental period, such as experiencing difficulties in male identificatio...

T Few dense underwater acoustic sensor networks (UWSN) currently exist because existing commercial acoustic modems are too expensive and power consuming. In order to enable the proliferation of UWSN, a new low-cost, low-power acoustic modem must be designed. This paper investigates the appropriate computational platform and presents the design of a complete FPGA implementation of a Frequency Sh...

background: the use of devices emitted microwave radiation such as mobile phones, wireless fidelity (wi-fi) routers, etc. is increased rapidly. it has caused a great concern; the researchers should identify its effects on people's health. we evaluated the protective role of vitamin c on the metabolic and enzymatic activities of the liver after exposure to wi-fi routers. material and methods: 70...

Ovine lentiviruses and caprine arthritis-encephalitis virus (CAEV) are prototypic lentiviruses that replicate predominantly in macrophages of infected animals. In situ hybridization of pathologically affected tissues from diseased animals has shown that viral RNA exists in permissive macrophages as well as in non-macrophage cell types that do not support productive virus replication. These find...

Mobile wireless networks are more vulnerable to unauthorised access and eavesdropping when compared with the traditional fixed wired networks due to the mobility of users, the transmission of signals through open-air and the requirement of low power consumption by a mobile user. This paper focuses on the security techniques used within the GSM standard. First, current GSM security system vulner...

A new type of Meteor Burst Communication (MBC) network is developed. Each unit of the network is based on a DSP board running a modem software. All the fundamental blocks and functions of a modem are implemented in software. Unlike hardware modems, this software modem has flexibility of system configuration and operation. The system implements adaptability in terms of modulation type (number of...

Open base transceiver station (BTS) project was originally developed using open-source Unix/Linux applications in conjunction with Universal Software Radio Peripheral (USRP) to implement GSM (Global System for Mobile Communications) air interface supporting GSM handsets at much lower cost than commercial carrier BTS systems. This paper emphasizes concepts and methodology of low cost Open BTS im...

This paper discusses the gap created by an international digital divide in Africa. The paper focuses on bridging the digital divide that exists between the developed countries and Africa, especially in the use of the internet and Global System Mobile (GSM) communication services. Issues like bridging the international digital divide, digital divide and Africa, bridging the digital divide in Afr...

This study was conducted to obtain the basic data of two common odorants-geosmin and 2-methylisoborneol (GSM and 2-MIB)-in environmental water. More specifically, the headspace solid-phase microextraction coupled to gas chromatography mass spectrometry (HS-SPME/GC-MS) was applied to determine the levels of GSM and 2-MIB in water samples, and the samples were collected depending on water sources...
