This memo presents the case for adding smaller antennas to the ALMA array. Smaller, higher precision antennas are better able to exploit the excellent submillimeter potential of the 5000 m altitude site, and are better matched to the angular size of many submillimeter sources. Model studies show that the image delity of mosaiced observations with the ALMA array will be limited by pointing and s...

This paper shows how the interaction between decentralized information gathering and discreteness of investment decisions at the individual level can generate random fluctuations in aggregate investment that involve occasionally large allocation errors. This interaction is illustrated in a model in which private information is costly to acquire and prices reveal information. The unique rational...

We study preferences estimated from finite choice experiments and provide sufficient conditions for convergence to a unique underlying “true” preference. Our are weak and, therefore, valid in wide range of economic environments. develop applications expected utility theory, over consumption bundles, menu choice. framework unifies the revealed preference tradition with models that allow errors.

Digital information system do poses errors, these errors are the consequence of path delay in communication system as some sort of errored signal processing to achieve an error free information. Error detection circuits are pivoted several tropology’s are being implied since the last three decade. In the past CMOS era we see how single electron transistor are incorporated to achieve error free ...

We present an approach to the problem of real-time identification of vehicle motion models based on fitting, on a continuous basis, parametrized slip models to observed behavior. Our approach is unique in that we generate parametric models capturing the dynamics of systematic error (i.e. slip) and then predict trajectories for arbitrary inputs on arbitrary terrain. The integrated error dynamics...

Semantic coherence is a higher-order coherence benchmark that assesses whether a constellation of estimates--P(A), P(B), P(B | A), and P(A | B)--maps onto the relationship between sets implied by the description of a given problem. We present an automated method for evaluating semantic coherence in conditional probability estimates that efficiently reduces a large problem space into five meanin...

Denmark has unique health informatics databases such as "The Children's Database" (CDB), which since 2009 has held data on all Danish children from birth until 17 years of age. In the current set-up a number of potential sources of error exist - both technical and human - which means that the data is flawed. The objective of this paper is both to clarify errors in the database and to enlighten ...

This paper presents experimental results for time-optimal control of robotic manipulators along specified paths. The implementation of time-optimal control represents several unique problems: (1) the control is generally discontinuous (bang-bang), (2) actuator dynamics are usually ignored in order to reduce the system order, and (3) the optimal control leaves no control authority to compensate ...

Data Quality has many dimensions one of which is accuracy. Accuracy is usually compromised by errors accidentally or intensionally introduced in a database system. These errors result in inconsistent, incomplete, or erroneous data elements. For example, a small variation in the representation of a data object, produces a unique instantiation of the object being represented. In order to improve ...

A human chromosome is a DNA molecule with approximately 10 8 base pairs. The techniques developed to date for sequencing are restricted to pieces of DNA with up to tens of thousands of base pairs. This means that when a piece is sequenced, only an extremely small part of a chromosome can be seen. Molecular biologists use special techniques to deal with DNA molecules comparable in size to a chro...
