    The work described in this thesis is aimed at the exploration of new methods\ud for the integration of design and test development procedures for mixedsignal\ud integrated circuits (IC's). Mixed-signal IC's are currently found in\ud many electronic systems, including telecommunications, audio and video\ud instruments, automotive parts, etc. The testing of these IC's presents\ud problems due to the complex nature of analog functionality and the nonautomated\ud analog design process. Automatic generation of test programs\ud for analog parts is a problem which is not yet fully solved. Once a test is\ud generated, formal methods to ensure the quality of developed tests do not\ud exist or have a large overhead. Systematic links between design and test\ud development processes of analog and mixed-signal circuits are required to\ud improve these points and to ensure high quality and low time-to-market\ud (TTM) for mixed-signal IC's

    An integrated model for cash transfer system design problem

    Get PDF
    This paper presents an integrated model that incorporates strategic, tactical, and operational decisions for a cash transfer management system of a bank. The aim of the model is to decide on the location of cash management centers, number and routes of vehicles, and the cash inventory management policies to minimize the cost of owning and operating a cash transfer system while maintaining a pre-defined service level. Owing to the difficulty of finding optimal decisions in such integrated models, an iterative solution approach is proposed in which strategic, tactical, and operational problems are solved separately via a feedback mechanism. Numerical results show that such an approach is quite effective in reaching greatly improved solutions with just a few iterations, making it a promising approach for similar integrated models

    Micro data on nominal rigidity, inflation persistence and optimal monetary policy

    The popular Calvo model with indexation (Christiano, Eichenbaum and Evans, 2005) and sticky information (Mankiw and Reis, 2002) model have guided much of the monetary policy discussion. The strength of these approaches is that they can explain the persistence of inflation. However, both of these theories are inconsistent with the micro data on prices. In this paper, I evaluate the consequences of implementing policies that are optimal from the perspective of models that overlook the micro-data. To do so, I employ a Generalized Taylor Economy (GTE) (Dixon and Kara, 2007). While there is no material difference between the GTE and its popular alternatives in terms of inflation persistence, a difference arises when it comes to the micro-data: the GTE is consistent with the micro-data. The findings reported in the paper suggest that policy conclusions are significantly affected by whether persistence arises in a manner consistent with the micro-data and that policies that are optimal from the perspective of the models that are inconsistent with the microdata can lead to large welfare losses in the GTEInflation persistence, DSGE models, Optimal Monetary Policy

    Optimal monetary policy in the generalized Taylor economy

    In this paper we use the Generalized Taylor Economy (GTE) framework in which there are many sectors with overlapping contracts of different lengths to analyze the design of monetary policy. We derive a utility based objective function of a central bank for this economy and use it to evaluate the performance of alternative simple rules. We find that a simple rule that targets an index that gives more weight to the sectors which have longer contracts and are more important in the aggregate index yields a welfare outcome nearly identical to the optimal policy. However, we find that potential gains in targeting sector specific inflation rates rather than the aggregate inflation rate is very sensitive to the shape of the distribution. We show that except for the cases where prices/wages are reoptimized very frequently, the performance of the sectoral rule can be closely approximated by a simple rule that targets aggregate inflation.
