An evaluation of energy efficient microcontrollers

2014 9th International Symposium on Reconfigurable and Communication-Centric Systems-on-Chip (ReCoSoC), 2014
The 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.

Efficiency Evaluation for the 3G and WiMAX

2009 Fifth International Joint Conference on INC, IMS and IDC, 2009
When the client moved quickly, from 3G into WiMAX service coverage, then leaved the WiMAX service coverage and accessed to another 3G range of services. At this time, that handoff frequently in a short period of time, and decreased system efficiency, also decreased the QoS. In this research, we use NS-2 to simulate the situations.

On the efficient evaluation of array joins

2015 IEEE International Conference on Big Data (Big Data), 2015
Array 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 ...

Chance Constrained Efficiency Evaluation

Management Science, 1995
A 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, 1986
The 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,

Towards efficient partial evaluation

Proceedings of the 1993 ACM SIGPLAN symposium on Partial evaluation and semantics-based program manipulation - PEPM '93, 1993
In general, a partial evaluator needs to keep track of the tasks that have already been completed or initiated, so that it can recognize when to stop unfolding. In the MIX-style polyvariant specialization algorithm, this is accomplished by a global log.

Efficient Evaluation of Matrix Polynomials

2018
We 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

Designing and evaluating an energy efficient Cloud

The Journal of Supercomputing, 2010
Cloud 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.

Efficiency evaluation of data warehouse operations

Decision Support Systems, 2007
We present an efficiency model for data warehouse operations and analyze a data set to evaluate the model. The model contains salient variables to evaluate the efficiency of an organization's data warehouse operations for refresh processing and query production. The variables in the model include resource consumption (labor usage and computing budgets),

Efficient Parallel Evaluation of Boolean Expressions

IEEE Transactions on Computers, 1976
A 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.
