data envelopment analysis operates as a tool for appraising the relative efficiency of a set of homogenous decision making units. this methodology is applied widely in different contexts. regarding to its logic, dea allows each dmu to take its optimal weight in comparison with other dmus while a similar condition is considered for other units. this feature is a bilabial characteristic which opt...

The University of Colorado Archives holds a substantial collection of audio recordings from the Conference on World Affairs (CWA), held annually at the University since 1948. Recordings of Conference sessions from the 1950s to the present comprise approximately 8,000 hours of material on reel‐to‐reel, cassette, and audio‐only VHS tapes. In 2009 the Archives, along with other units of the CU Lib...

Closed world assumptions” (CWAs) are an important class of implicit completions for logic databases. We present a new general definition of CWA; it is parameterized, so that known and new versions of CWAs can be derived as special cases. Our CWA, in turn, instantiates the more basic notion of “database completion” and satisfies natural properties. It can even be characterized by the property of...

Successful implementation of water-quality management requires accurate scientific knowledge of water systems and sound judgment about environmental policy. This dual requirement calls for interactions between water scientists, managers, and policy experts who can jointly interpret and synthesize the data necessary for decision-making. With regard to non-point source (NPS) pollution in the Unit...

The need for effective methods for the detection and measurement of chemical warfare agents (CWA) has increased in recent years. Current stockpiles need to be monitored to ensure their safe containment. The remediation of sites containing abandoned CWAs requires analysis in support of safe removal and destruction of agents. More recently, counterterrorism efforts have underscored the need for m...

Sound exposure effects have been investigated by broadcasting a group of broilers with sound of Quran verses (Group B) whereas the other group is the control broilers (Group C). The growth rate comparisons in terms of weight and raw meat texture measured by shear force have been investigated. Twenty-seven broilers were randomly selected from each group on Day 24 and weight measurement was carri...

Background: Chemical warfare agents (CWA) were most notably used during the First World War in Europe, against Iranians and Kurdish citizens of Iraq at the hands of Saddam Hossein’s regime in 1980s and more recently in Syria. The use of CWA is banned under the international law. Methods: Ancient uses of CWA are not well studied. Recently, their use during the Persian siege of the Roman-held Dur...

Sea dumping of chemical warfare (CW) took place worldwide during the 20th century. Submerged CW included metal bombs and casings that have been exposed for 50–100 years corrosion are now known to be leaking. Therefore, arsenic-based agents (CWAs), pose a potential threat marine ecosystems. The aim this research was support need real-data measurements accurate risk assessments categorization thr...

To alleviate the negative impact of noise on wireless federated learning (FL), we propose a channel-weighted aggregation scheme FL (CWA-FL), in which parameter server (PS) makes gradients according to channel conditions devices. In proposed scheme, are transmitted PS an uncoded way through orthogonal multiple access (OMA) channel, can avoid synchronization issue among devices faced by over-the-...
