An Efficient Fault Detection of FPGA and Memory Using Built-in Self Test [BIST

In this paper, a new technique for localization of fault detection and diagnosis in the interconnects and logic blocks of an arbitrary design implemented on a Field-Programmable Gate Array (FPGA) using BIST is presented. This technique can uniquely identify any single bridging, open or stuck-at fault in the interconnect as well as any single functional fault, a fault resulting a change in the truth table of a function, in the logic blocks. The test pattern generator and output response analyzer are configured by existing CLBs in FPGAs; thus, no extra area overhead is needed for the proposed BIST structure. The scheme also rests on partitioning of rows and columns of the memory array by employing low cost test logic. It is designed to meet requirements of at-speed test thus enabling detection of timing defects. Experimental results confirm high diagnostic accuracy of the proposed scheme and its time efficiency.

Localization of Light with Two Metallic Wedges: A Step Toward Surface Plasmon Sources

A new technique for localization of the light in subwavelength scale is proposed by using two adjacent metallic wedges, which are made by different metals, i.e., Al and Ag. Green’s function surface integral equation method is exploited to numerically calculate magnetic field at different points. The results illustrate that by controlling the phase difference between two surface plasmon polariton waves propagating on the sides of the first wedge and the distance between two wedges the amplitude and the phase of SPP waves generated on the sides of the second wedge can be adjusted.

Exploiting indoor location and mobile information for context-awareness service

Personal mobile devices such as cellular phones, smart phones and PMPs have advanced incredibly in the past decade. The mobile technologies make research on the life log and user-context awareness feasible. In other words, sensors in mobile devices can collect the variety of user’s information, and various works have been conducted using that information. Most of works used a user’s location information as the most useful clue to recognize the user context. However, the location information in the conventional works usually depends on a GPS receiver that has limited function, because it cannot localize a person in a building and thus lowers the performance of the user-context awareness. This paper develops a system to solve such problems and to infer a user’s hidden information more accurately using Bayesian network and indoor-location information. Also, this paper presents a new technique for localization in a building using a decision tree and signals for the Wireless LAN because the decision tree has many advantages which outweigh other localization techniques.

A new technique for localization of hepatic tumors that are poorly visible with CT fluoroscopy

The purpose of this study was to report a new technique for localization of hepatic tumors that are poorly visible with CT fluoroscopy. Forty-three hepatocellular carcinomas were not visible with CT fluoroscopy. A 22-gauge Chiba end-hole needle was inserted in the approximate location of a lesion estimated on the basis of anatomical landmarks demonstrated on both previous MR and CT images. We injected 3 ml of a mixture of nonionic contrast material and saline solution. Following the first injection, contrast solution filled the hepatic lesion in 29 of 43 cases. In 8 of 43 cases, contrast solution was distributed in the normal surrounding liver. In 7 of these 8 cases, repositioning allowed us to adjust the needle in the tumor. In the other 6 of 43 cases, contrast solution spread within capsule or pseudocapsule (pattern 3). In all 6 cases, repositioning allowed to adjust the needle in the tumor. This new technique allows an accurate localization of hepatic tumors that are poorly visible with CT fluoroscopy.

Recent Advances in Minimally Invasive Pancreatic Surgery

For curative resection of pancreatic endocrine tumours, minimally invasive methods of pancreatic surgery, such as laparoscopy, should be indicated only for benign tumours. Among these uncommon tumours, pancreatic insulinomas are mostly benign and solitary. Successful management of patients with insulinomas relies on accurate localization of the tumour and the use of appropriate surgical techniques. Because of the small size of these tumours, conventional intraoperative ultrasonography combined with palpation has been widely regarded as the best localization procedure. Because contact ultrasonography, a new technique for localization of pancreatic lesions, can be used laparoscopically, several surgeons have used laparoscopy not only for localization, but also for resection of insulinomas. In the era of minimally invasive surgery for benign pancreatic lesions, we attempted laparoscopic-focused exploration of the pancreas for resecting insulinomas based on preoperative localization. We describe the use of this technique for the detection and resection of insulinomas and the results obtained, with a review of previous reports.

Acoustic emission method for testing oil and gas tanks

Results of practical hydraulic tests of railway tanks owned by Altaivagon Corporation by the method of acoustic emission (AE) are given. A new technique for localization of AE signals and an appropriate software package have been developed to detect with a high certainty both internal and penetrating flaws in tanks under a load of 0.5 atm. A technique for estimating the hazard presented by the flaws in railway tanks based on detection of AE signals is discussed.

A new technique for localization of cellulase in situ using silver nitrate.

A new staining technique has been developed for the histochemical localization of cellulase in plant tissues by light microscopy. The products of cellulolysis are reducing sugars which can reduce the salts of heavy metals under appropriate conditions. The present technique relies on the deposition of black silver oxide due to reduction of alkaline silver nitrate to detect cellulase in tissues.

Intra-uterine transfusions. Two interesting cases.

SINCE Liley's introduction of fetal transfusion, 1 there has been a complete revision of thought regarding the management of erythroblastosis fetalis. The following two patients illustrate an additional benefit heretofore unreported. In these patients, in utero transfusion eliminated the necessity of postdelivery exchange transfusions. Further, utilization of a new technique for localization of the fetal peritoneal cavity may significantly reduce the risk of fetal damage. These cases also point to the need for establishing new standards for such procedures, for undoubtedly such cases are more common than one is made to think from reviewing the literature. A review of the literature is included. Report of Cases Case1.—A 34-year-old gravida 4 para 3, was first examined in October 1965. Her last menstrual period was on Aug 5, 1965. Physical examination confirmed the presence of an intrauterine gestation consistent with the period of amenorrhea. Laboratory examination revealed type A blood,
