Build-in-Self-Test of FPGA for diagnosis of delay fault

Abstract: The recent trend of reconfigurable hardware and convergence of hardware platform in embedded system have enhanced the application of FPGAs. Although the capability and performance of FPGA have advanced, the testing of FPGAs both online and off-line (manufacturer oriented testing) poses a major challenge. Importance of delay testing has grown especially for high-speed circuits. Even presence of small delay fault may cause any critical path to fail. As delay testing, using automatic test equipment is found to be quite expensive; BIST (Built-In-Self-Test) can significantly reduce the cost of delay fault detection without using extra hardware. We have presented a BIST structure to test delay fault of various resources and interconnects of FPGA. The proposed scheme can be implemented for both online as well as off-line testing. We have also proposed a new 3-diagnosable BISTer structure that improves the testing efficiency of our BISTer. The proposed technique can detect the presence of fault, even if all the three units ( TPG, ORA, BUT) in a BIST are faulty. We have simulated our method in Xilinx Vertex-II FPGA, using ISE tool Jbits3.0 API and XHWI (Xilinx Hardware Interface) provided by Xilinx and MATLAB7.0.

How Valuable is Credit Card Lending

Abstract: Standard methodology for valuing interest-dependent assets is by now well established, with the Heath-Jarrow-Morton (HJM) model being one of the most widely-used approaches. However, despite representing a significant portion of many banks9 portfolios, credit card loans as an asset class have not been brought into the standard valuation framework. Like a bond position, valuing a bank9s credit card loan portfolio involves projecting the levels of future interest rates. But a portfolio of credit card loans also has several special features not shared by bonds. One is that the total loan face value shows long-run growth, but also short-term fluctuation, reflecting both seasonal effects and interest rate changes. A second is that the profitability, and hence the capitalized value, of the loan portfolio depends on the difference between the rate earned on the loans and the rate the bank must pay to fund those loans, so both rates need to be modeled. In this article, Chatterjea, Jarrow, Neal, and Yildirim offer a general modeling approach for valuing a bank9s credit card loan portfolio within an extended HJM paradigm, and then illustrate how it works by fitting it to the credit card portfolios of five different banks.

Learning with an Embedded Reject Option

Abstract: The option to reject an example in order to avoid the risk of a costly potential misclassification is well-explored in the pattern recognition literature. In this paper, we look at this issue from the perspective of statistical learning theory. Specifically, we look at ways of modeling the problem of learning with an embedded reject option, in terms of minimizing an appropriately defined risk functional, and discuss the applicability thereof of some fundamental principles of learning, such as minimizing empirical risk and structural risk. Finally, we present some directions for further theoretical work on this problem.

Dynamics of Multiple Memories Reflections From an Inquiry

Abstract: In this article, the author reflects on how a study on “organizational memory” in the context of software development firms in India brought forth a number of issues associated with choices in research. He proposes the conceptualization of organizational memory in heterogeneous, multiple kinds of ways, emphasizing its plurality and explores how this can be done along varied dimensions. He also demonstrates how these findings in turn influenced the ensuing doctoral work, including the framework chosen and the methodology adopted.
