The paper “ARM Based Agricultural Field Monitoring System using GSM” is mainly focused on modernizing the irrigation technology in agriculture and also to provide adequate irrigation in particular area. The set up consists of mainly ARM7TDMI core and GSM. GSM serves as an important part as it is responsible for controlling the irrigation on field and sends them to the receiver through coded sig...
Gastrin stimulates the growth of gastric mucosa by increasing mostly its glandular region but is not known to induce the growth of a pit region where its major constituent cells, gastric surface mucous (GSM) cells, turn over rapidly. To investigate the effect of gastrin on GSM cells, we generated hypergastrinemic mice by expressing a human gastrin transgene. We obtained a hypergastrinemic mouse...
Poor accuracy of frequency references used in GSM Base Transceiver Stations (BTS) can lead to dropped calls, slow handover between cells and even co-channel interference. In this paper, we report some results of an experimental trial carried out in the Omnitel-Vodafone test plant in Milano (Italy). In authors' knowledge, this is the first paper confirming with experimental data that lack of B...
In real-life applications, errors in the speech recognition system are mainly due to inefficient detection of speech Ž . segments, unreliable rejection of Out-Of-Vocabulary OOV words, and insufficient account of noise and transmission channel effects. In this paper, we review a set of techniques developed at CNET in order to increase the robustness to mismatches between training and testing con...
This paper describes a multi-rate codec family developed as a potential candidate for the GSM Adaptive Multi Rate (AMR) codec standard. The codec family consists of the GSM Enhanced Full Rate (EFR) codec [I] and lower bit-rate extensions thereof: The codec family consists of several codecs, i.e., modes that have different bit-rate partitionings between source coding and error protection. All th...
The Global System for Mobile Communication (GSM) is a popular mobile communication standard. GSM networks collect personal communication information required for the billing of its subscribers. These communication records, known as Call Data Records (CDRs), may infringe on basic subscriber privacy principles as personal details of performed network events are managed and stored by the serving G...
It has been nearly 60 years since the introduction of Gough–Stewart manipulator (GSM). With advantages superior load capacity and high precision, GSM still plays an important role in many fields. However, limitations such as a small workspace complex singularities. To overcome these problems, novel kinematically redundant parallel robot is designed with three actuators added on basis GSM. First...
the place of information in addressing market access and participation limitation, which hinders farmer’s welfare and poverty reduction efforts in many developing countries, cannot be over-emphasized. this study therefore examined the use of mobile phone in the marketing of food crops among farming households in rural south east, nigeria. a multi stage sampling procedures was used in the select...
BACKGROUND Adults infected with HIV have increased atherosclerosis potentially associated with both HIV and non-HIV associated factors. We characterized risk factors for atherosclerosis as measured by noninvasive vascular imaging. METHODS AND RESULTS We used B-mode ultrasound to examine levels and correlates of echogenicity and vessel wall thickness of the carotid artery intima-media complex ...
Right after its introduction, GSM security was reviewed in a mostly theoretical way, uncovering some major security issues. However, the costs and complexity of the required hardware prohibited most people from exploiting these weaknesses in practice and GSM became one of the most successful technologies ever introduced. However, there is an enormous amount of mobile enabled equipment out there...
