We find that the performance distribution of the individual stocks inside a mutual fund can toss out additional information about the fund manager’s stock picking ability. When a mutual fund contains mostly mediocre-performing stocks but one super-performer, it is likely that the overall fund performance, albeit good, would be due to luck. On the other hand, a fund that has a larger number of a...

This paper is aimed at evaluating the performances of different measures which have been proposed in literature for robust matching. In particular, classical matching metrics typically employed for this task are considered together with specific approaches aiming at achieving robustness. The main aspects assessed by the proposed evaluation are robustness with respect to photometric distortions,...

The global development of the world has an adverse affect on the natural environment, such as global warming, is continuing to mount. Green manufacturing systems that focus on minimizing environmental impact of manufacturing processes and products are ever more important to sustain our future. Green manufacturing systems are slow to gain acceptance as manufacturers are focusing more on implemen...

Some general arguments in the light of the application of the inorganic crystal scintillators in the search for rare processes are addressed. The continuous innovation provided by physics, chemistry and technology in their development allows the improvement of their performances. Also the possibility of detectors exploiting new materials is open and the further application to this field of rese...

The Alice and LHCb collaborations equipped their detectors with many technologies to identify particles in a large momentum range, both in the barrel and the forward regions. The methods used are described and some details on the hardware implementation are given. A few physics results illustrate the performances obtained by the two detectors.

As the offshore market faces deepwater production challenges, the oil and gas industry is investing in new technologies to bring down the costs in the subsea fields exploitation. A breakthrough technology solution is the development of a subsea centrifugal compressor module installed on the seabed, transporting the wellstream to a central platform or directly to shore. The typical application o...

The EA Sports Player Performance Index is a rating system for soccer players used in the top two tiers of soccer in England—the Premier League and the Championship. Its development was a collaboration among professional soccer leagues, a news media association, and academia. In this paper, we describe the index and its construction. The novelty of the index lies in its attempts to rate all play...

In this paper, alternative approaches to structure the parametric geometry in relation to information on various performances are described and exemplified. They relate to different levels of knowledge that concern the performances considered in the process and which are available to the designer while the parametric model is being set. A theoretic framework embeds the different approaches, for...

An intention to adopt IP protocol for future mobile communication and subsequent extension of Internet services to the air interface calls for advanced performance modeling approaches. To provide a tool for accurate performance evaluation of IP-based applications running over the wireless channels we propose a novel cross-layer wireless channel modeling approach. We extend the small-scale propa...

Abstract: Let Y be a Gaussian vector of R of mean s and diagonal covariance matrix Γ. Our aim is to estimate both s and the entries σi = Γi,i, for i = 1, . . . , n, on the basis of the observation of two independent copies of Y . Our approach is free of any prior assumption on s but requires that we know some upper bound γ on the ratio maxi σi/mini σi. For example, the choice γ = 1 corresponds ...
