We constructed systems with neural networks using one-dimensional numeric sequences from chest X-ray images for detection of abnormal areas and investigated the effect of pre-processing for input patterns on performance of the systems. We changed the number of data in one-dimensional numeric sequences, and applied differential filters to the sequences.(More)
We constructed neural network systems using one-dimensional numeric sequences from X-ray images of chest for detection of abnormal areas in the images and investigated the effect of number of input layer units on performance of the systems. In order to construct the neural networks with different number of input layer units, we changed the number of data in(More)
In order to remove high noise of the CT image reconstructed by a hard kernel efficiently and to minimize the number of images to be added, we constructed the system to fit the discrete data to a continuous function and developed the algorithm which calculate the MTF through a curve fitting technique with two steps. From the results, we found that the MTF(More)
Although the presence of an oxygen reservoir (OR) is assumed in many models that explain resistive switching of resistive random access memory (ReRAM) with electrode/metal oxide (MO)/electrode structures, the location of OR is not clear. We have previously reported a method, which involved the use of an AFM cantilever, for preparing an extremely small ReRAM(More)
A 64-year-old man underwent radical esopha-gectomy for cancer and simultaneous reconstruction using the gastric conduit through the posterior mediastinum. Two courses of adjuvant chemotherapy were performed. Twenty-eight months postoperatively, recurrence of the cancer was detected in the mediastinal lymph nodes, and he underwent concurrent(More)
We constructed measurement systems for fatigue using the F-values and the ΔF-values, and investigated their performance. The system consisted of four units, which are generation of fatigue, data-collection, data-processing and estimation. In addition, we classified the fatigue into 3 types, which are physical, mental and mix fatigues. From the(More)
