This study emphasizes the simulation and analysis of the compensatory effect of temperature on automatic gain control (AGC). From the analytical results, a temperature regulation mechanism was proposed. The technology most appropriate for and adaptive to mobile terminal stations under various temperatures was considered to ensure excellent transfer quality of the mobile terminal station. Finall...

This paper presents a Particle Swarm Optimization (PSO) based Model Predictive Control (MPC) scheme applied to Automatic Generation Control (AGC) systems. The proposed scheme formulates the MPC as an optimization problem and PSO is used to find its solution. Single area AGC model is taken incorporating Generation Rate Constraint (GRC) nonlinearities and constraints on the control input. Two int...

BACKGROUND Follow-up endoscopy after total gastrectomy for gastric cancer is commonly performed without there being any definite evidence of clinical relevance. Therefore, we investigated the role of the upper endoscopic examinations after total gastrectomy for gastric cancer. METHODS The medical records of 212 early gastric cancer (EGC) patients and 622 advanced gastric cancer (AGC) patients...

Previous work has shown that it is feasible to implement a fully digital test evaluation function to realise partial selftest on an automatic gain control circuit (AGC). This paper extends the technique to INL, DNL, offset & gain error testing of analogue to digital converters (ADC's). It also shows how the same function can be used to test an AGC / ADC pair. An extension to full self-test is a...

Lymph node metastasis plays a crucial role in predicting prognosis in advanced gastric cancer (AGC). In the present study, we formulated a fibrosis ratio (FR), defined as the number of metastatic lymph nodes with fibrosis divided by the total number of lymph nodes, and sought to determine whether it can be used to predict the prognosis of patients with AGC and improve on existing node staging. ...

We report the discovery of a simple environmental sensing mechanism for biofilm formation in the bacterium Bacillus subtilis that operates without the involvement of a dedicated RNA or protein. Certain serine codons, the four TCN codons, in the gene for the biofilm repressor SinR caused a lowering of SinR levels under biofilm-inducing conditions. Synonymous substitutions of these TCN codons wit...

This paper presents a newly proposed Model Predictive (MPC) scheme featuring Particle Swarm Optimization (PSO) technique applied to nonlinear single area Automatic Generation Control (AGC). The proposed scheme formulates the MPC as an optimization problem and PSO is used to find its solution. Single area AGC model is used and it incorporates Generation Rate Constraint (GRC) nonlinearities and c...
