As well as introducing key areas of design with insider's knowledge, Tim focuses on the art of designing circuits so that every production model will perform its specified function - and no other unwanted function - reliably over its lifetime. The combination of design alchemy and awareness of commercial and manufacturing factors makes this an essential companion for the professional electronics designer.Electronic circuit designElectrical & Computer EngineeringHILCCEngineering & Applied SciencesHILCCElectrical EngineeringHILCCElectronic books.Electronic circuit design.Electrical & Computer EngineeringEngineering & Applied SciencesElectrical Engineering621.3815Williams Tim309408AU-PeELAU-PeELAU-PeELBOOK9910457686203321The Circuit Designer's Companion2118824UNINA02749nam 2200529 a 450 991083061950332120230721003737.01-119-20893-91-281-94013-597866119401330-470-72534-6(CKB)1000000000557043(EBL)366752(OCoLC)297117538(SSID)ssj0000230547(PQKBManifestationID)12059971(PQKBTitleCode)TC0000230547(PQKBWorkID)10198352(PQKB)10583890(MiAaPQ)EBC366752(EXLCZ)99100000000055704320070830d2007 uy 0engur|n|---|||||txtccrPublic sector auditing[electronic resource] is it value for money? /Sir John BournChichester, England ;Hoboken, NJ John Wiley & Sonsc20071 online resource (428 p.)Description based upon print version of record.0-470-05722-X Includes bibliographical references (p. [379]-390) and index.Introduction -- Why bureaucracy will never work -- The failure to analyse outcomes -- How effective audit can be secured : the auditor as [c]oach and mentor rather than critic and nark -- Privatisation : the alternative to bureaucracy? -- Public private partnerships : another option -- Regulations : bureaucracy's tentacles -- Meeting citizens' needs : quality of public services -- Risk averse or risk ignorant? -- Vulnerability to fraud, theft and corruption -- Programme and project management : bureaucracies' weakest link? -- Performance measurement : clarity or confusion? -- Organising the audit -- Concluding thoughts.Drawing on 20 years of experience as Comptroller and Auditor General, and head of the United Kingdom National Audit Office, Public Sector Auditing: Is it Value for Money? is Sir John Bourn's own account of the role and influence value for money auditing has in holding governments to account and in helping public bodies improve the ways in which they deliver services. Key features include:In-depth case studies from UK, US, Canada, China, India and Australia;Detailed analysis of complex areas of public expenditure such as health, education, privatisation, regulation, defenceFinance, PublicAuditingFinance, PublicAuditing.657.835657/.835Bourn JohnSir,1934-1713812MiAaPQMiAaPQMiAaPQBOOK9910830619503321Public sector auditing4107084UNINA
