Ranked voting data arise when voters select and rank more than one candidate with an order of preference. Cook et al.[1] introduced data envelopment analysis (DEA) to analyze ranked voting data. Obata et al.[2] proposed a new method that did not use information obtained from inefficient candidates to discriminate efficient candidates. Liu et al.[3] ranked efficient DMUs on the DEA frontier with...

evaporation of micro-liter drops from solid surfaces at room condition is mainly governed by diffusion. therefore, there should be no difference between evaporation rate of sessile and pendant drops. however, some studies indicate a difference and explain the difference using buoyancy. the objective here is to reconcile the inconsistency in the literature. for that, first, by comparing two iden...

凝固波形解析（clot waveform analysis: CWA）は自動凝固分析装置を用いた凝固機能評価法として発展している．CWAはプロトロンビン時間（prothrombin time: PT）や活性化部分トロンボプラスチン時間（activated partial thromboplastin APTT）の “凝固時間” のみならず，装置内で解析した結果を画面に表示することができ，汎用性が高いため，臨床検査室で凝固異常症の迅速な鑑別ができる．近年，CWAが出血性疾患だけでなく，血栓傾向を示す疾患に有用だと報告された．今後は，波形による鑑別の精度向上が課題である．一方，APTTによる凝固反応の後，フィブリン溶解過程を評価できる凝固線溶波形解析（clot fibrinolysis CFWA）が登場した．CFWAは，間接的に凝固のみならず線溶能や線溶抑制効果を反映する画期的な方法で，...

Recently, in (Loyer & Straccia 2005) the Any-World Assumption (AWA) has been introduced for normal logic programs as a generalization of the well-known notions of Closed World Assumption (CWA) and the Open World Assumption (OWA). The AWA allows any assignment (i.e. interpretation), over a truth space (bilattice), to be a default assumption and, thus, the CWA and OWA are just special cases. Whil...

Data envelopment analysis (DEA) calculates the relative efficiency of homogenous decision-making units (DMUs) with multiple inputs and outputs. Classic DEA models usually suffer from several issues such as: discrimination power, variable weights of inputs/outputs, inaccurate efficiency estimation for small number of DMUs, incapability in working with zero and negative data, and not having exter...

IntroductIon Typically, relational databases operate under the Closed World Assumption (CWA) of Reiter (Reiter, 1987). The CWA is a metarule that says that given a knowledge base KB and a sentence P, if P is not a logical consequence of KB, assume ~P (the negation of P). Thus, we explicitly represent only positive facts in a knowledge base. A negative fact is implicit if its positive counterpar...

  A data envelopment analysis (DEA) method can be regarded as a useful management tool to evaluate decision making units (DMUs) using multiple inputs and outputs. In some cases, we face with imprecise inputs and outputs, such as fuzzy or interval data, so the efficiency of DMUs will not be exact. Most researchers have been interested in getting efficiency and ranking DMUs recently. Models of th...

in this paper, a new revenue efficiency data envelopment analysis (re-dea) approach is considered for finding the most revenue efficient unit with price uncertainty in both optimistic and pessimistic perspectives. the optimistic and pessimistic perspectives use efficient frontier and inefficient frontier, respectively. an integrated model is introduced to find decision making units (dmus) that ...
