For a fault-tolerant SBW (Steer-By-Wire) system, two structural designs with and without a backup mechanical coupling are proposed and assessed by a unified approach from a reliability point of view. An operation procedure to cope with partial system degradations prior to a complete loss of steering is presented for each design. The procedure can be(More)
Steer-by-wire (SBW) systems, which have no mechanical linkage between the steering wheel and front wheels, are expected to improve vehicle safety through better steering capability. SBW system failures, however, can cause hazardous driving situations. This paper introduces fault-tolerant architecture based on diversified steering mechanisms consisting of(More)
A 60s male was admitted to our hospital for a diagnosis of gastric tumor sized 20 mm in diameter at the fornix of the stomach. Endoscopic mucosal resection (EMR) was performed, and the resected tumor was pap, m, ly0, v0, HMX, VM0, pathologically. One month after the EMR, the local recurrence was confirmed and a partial gastrectomy was performed.(More)
We report two cases of neuroendocrine carcinoma of the rectum. CASE 1: A 50s woman was diagnosed as rectal cancer and underwent anterior resection of the rectum and lymphnode dissection. The histological diagnosis was neuroendocrine carcinoma with peritoneal dissemination. She was treated with chemotherapy as an outpatient. One year later from the(More)
We report a case of multiple liver metastases of rectsigmoid colon cancer treated with systemic chemotherapy and hepatectomy. A 40s woman had undergone anterior resection of rectum for rectsigmoid colon cancer with multiple liver metastases. Then FOLFOX4 regimen was performed fifteen times, and FOLFIRI regimen was performed eleven times. After chemotherapy(More)
We describe herein a 72-year-old woman with tumor recurrence in the residual pancreas and metastasis to the liver following a pylorus-preserving pancreatoduodenectomy for multiple endocrine tumors in the head of the pancreas. Abdominal ultrasonography performed 7 years after the initial surgery detected new lesions in the residual pancreas and liver. After(More)
UNLABELLED The expandable metallic stent (EMS) have been used to treat obstructive colorectal cancer. We used EMS in 13 out of 14 cases of obstructive colorectal carcinoma patients (insertion rate 93%). Of these 13 cases, 6 cases were male patients, and 7 cases were female patients. The average age was 69.1-years-old (44-87). The placement of insertion part(More)
We report a case of gastric metastasis of lung cancer performed gastrectomy for the primary foci. A 70s woman was diagnosed as having right lung cancer and underwent right lower lobectomy and lymph node dissection. The histological diagnosis was adenocarcinoma (pT4, N2, M0). Four years later, positron emission tomography (PET)-CT revealed a tumor in the(More)
