Chance Constrained Efficiency Evaluation
Management Science, 1995A model for efficiency evaluation based upon the theory of chance constrained programming is developed. The model uses a piecewise linear envelopment of confidence regions for observed stochastic multiple-input multiple-output combinations in the Data Envelopment Analysis (DEA) tradition.

Efficient evaluation of multivariate polynomials
Computer Aided Geometric Design, 1986The authors give an algorithm to evaluate a polynomial of total degree d defined on a triangle T in the plane, \[ p(r,s,t)=\sum^{d}_{i=0}\sum^{i}_{j=0}c_{d-i,i-j,j}\cdot r^{d- i}s^{i-j}t^ j, \] where \(c_{d-i,i-j,j}=(d!/(d-i)!(i-j)!j!)b_{d- i,i-j,j}\), \(0\leq j\leq i\), \(0\leq i\leq d\), and (r,s,t) are the barycentric coordinates of each point in T,

Efficient Evaluation of Matrix Polynomials
2018We revisit the problem of evaluating matrix polynomials and introduce memory and communication efficient algorithms. Our algorithms, based on that of Patterson and Stockmeyer, are more efficient than previous ones, while being as memory-efficient as Van Loan’s variant. We supplement our theoretical analysis of the algorithms, with matching lower bounds

Efficient Private Function Evaluation
2021Private function evaluation (PFE) allows two or more parties to jointly compute a private function of one of the parties on the private inputs of the other parties securely. PFE can provide a viable solution in a scenario where a server holding a function that is his intellectual property or trade secret would like to compute this function on a client ...

Evaluation of thermophotovoltaic conversion efficiency
Journal of Applied Physics, 1982The theory and the experiments on thermophotovoltaic (TPV) conversion are reported in this paper. The various parameters characterizing TPV systems are studied in order to provide design information for actual converters. Both the experimental results and theoretical calculations of TPV conversion efficiency are presented for comparison.

On the efficient evaluation of array joins
2015 IEEE International Conference on Big Data (Big Data), 2015Array Databases close a gap in the database ecosystem by adding modeling, storage, and processing support on multi-dimensional arrays. Declarative queries provide processing of arrays of regularly massive size, such as Tera-to Petabyte datacubes, while allowing internal degrees of freedom in partitioning the large arrays into tractable sub-arrays ...

An evaluation of energy efficient microcontrollers
2014 9th International Symposium on Reconfigurable and Communication-Centric Systems-on-Chip (ReCoSoC), 2014The latest technological trends in many application fields e.g. the Internet of Things call for highly power efficient solutions. These solutions can be realised with current low power off the shelf microcontrollers. However the task of selecting the appropriate microcontroller is more difficult than it seems.

Efficient Parallel Evaluation of Boolean Expressions
IEEE Transactions on Computers, 1976A Boolean expression wilth n literals, i.e., n distinct appearances of variables, can be evaluated by a parallel processing system in at most 1.81 log2n steps, or, equivalently, by a network constructed with two-input AND and OR gates and having at most 1.81 log2n levels.

Designing and evaluating an energy efficient Cloud
The Journal of Supercomputing, 2010Cloud infrastructures have recently become a center of attention. They can support dynamic operational infrastructures adapted to the requirements of distributed applications. As large-scale distributed systems reach enormous sizes in terms of equipment, the energy consumption issue becomes one of the main challenges for large-scale integration.
