A survey of scan-capture power reduction techniques

With the advent of sub-nanometer geometries, integrated circuits (ICs) are required to be checked for newer defects. While scan-based architectures help detect these defects using newer fault models, test data inflation happens, increasing test time and test cost. An automatic test pattern generator (ATPG) exercise’s multiple fault sites simultaneously to reduce test data which causes elevated switching activity during the capture cycle. The switching activity results in an IR drop exceeding the devices under test (DUT) specification. An increase in IR-drop leads to failure of the patterns and may cause good DUTs to fail the test. The problem is severe during at-speed scan testing, which uses a functional rated clock with a high frequency for the capture operation. Researchers have proposed several techniques to reduce capture power. They used various methods, including the reduction of switching activity. This paper reviews the recently proposed techniques. The principle, algorithm, and architecture used in them are discussed, along with key advantages and limitations. In addition, it provides a classification of the techniques based on the method used and its application. The goal is to present a survey of the techniques and prepare a platform for future development in capture power reduction during scan testing

Government employment and pay : a global and regional perspective

The authors try to replace myths about government pay and employment with reliable facts from a survey for about 100 countries in the early 1900s. The study also outlines the general nature of civil service problems in the different regions. Nevertheless, while the facts are useful to"flag"possible problems and initiate a dialogue, recommendations for reform must be based on country-specific analysis. Globally, government employment is negatively associated with wages, and positively with the fiscal deficit (although the availability of financing is more important) and with per capita income (confirming"Wagner's Law"). But the global results stem almost entirely from strong results for Africa and Latin America. Civil service reform has suffered in the past from an overemphasis on retrenchment for fiscal reasons. Its true objective, for each country, is to achieve a civil service of the size and skill-mix, incentives, professional ethos, and accountability needed to provide public goods, help formulate and enforce the rules, and intervene to remedy market failures -as these government roles happen to be defined in the country in question. Civil service reform can begin with various diagnostic and fact-finding activities. The key measures concern rightsizing, incentives, and accountability. These are all relative notions: the right size of the workforce depends on the roles assigned to government; wage adequacy depends on private compensation levels; and strengthening of accountability must define accountability for what and to whom. When retrenchment is warranted, it must be carried out with great care to avoid skill reduction, demoralization, and lower-quality service. Adequate compensation is a must, and wage compression isto be avoided. But performance bonuses, popular in some advanced countries, have been only marginally effective in improving performance in developing countries, even in the private sector. And they can be dangerous in countries with ethnic, clan, or religious conflicts. Finally, improvements in accountability will most often require greater external openness and systematic feedback from service users.Banks&Banking Reform,Enterprise Development&Reform,Municipal Financial Management,Decentralization,Environmental Economics&Policies,National Governance,Banks&Banking Reform,Municipal Financial Management,Environmental Economics&Policies,Economic Policy, Institutions and Governance

Vascular Surgery

This book aims to provide a brief overview of conventional open vascular surgery, endovascular surgery and pre- and post-operative management of vascular patients. The collections of contributions from outstanding vascular surgeons and scientists from around the world present detailed and precious information about the important topics of the current vascular surgery practice and research. I hope this book will be used worldwide by young vascular surgeons and medical students enhancing their knowledge and stimulating the advancement of this field

Do Report Cards Tell Consumers Anything They Don't Already Know? The Case of Medicare HMOs

The use of government-mandated report cards to diminish uncertainty about the quality of products and services is widespread. However, report cards will have little effect if they simply confirm consumers' prior beliefs. Moreover, documented "responses" to report cards may reflect learning about quality that would have occurred in their absence ("market-based learning"). Using panel data on Medicare HMO market shares between 1994 and 2002, we examine the relationship between enrollment and quality before and after report cards were mailed to 40 million Medicare beneficiaries in 1999 and 2000. We find evidence that consumers learn from both public report cards and market-based sources, with the latter having a larger impact during our study period. Consumers are especially sensitive to both sources of information when the variance in HMO quality is greater. The effect of report cards is driven by beneficiaries' responses to consumer satisfaction scores; other reported quality measures such as the mammography rate did not affect enrollment decisions.
