Finding the aspect-ratio of an imaging system
Proceedings. 1991 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2002Aspect-ratio is a fundamental parameter of an imaging system. It determines the extent of nonuniformity in sampling. Video signals guarantee a one-to-one match between the camera lines and the lines in the image buffer. The horizontal arrangement of pixels, however. undergoes a resampling due to the digitization process.

The Controlling concept which bases on the RL ratio system (the name derives from the German“Rtentabilitat”, which is “profitability” in English and liquidity), presents a combination including descriptive, explanatory, and normative elements. Its enlarged version consists of the RL balance sheet-ratio system (RL-B) and the RL Controlling-ratio system (

Parallel Ratio Based CF for Recommendation System
Proceedings of the 7th International Conference on Computing Communication and Networking Technologies, 2016With the increase in E-commerce, Recommendation Systems are getting popular to provide recommendations of various items (movies, books, music) to users. To build the Recommendation System (RS), Collaborative Filtering (CF) techniques are proven efficient. From the main two Collaborative Filtering techniques i.e.

Characteristic ratio assignment in fractional order systems
ISA Transactions, 2010In this paper the characteristic ratios and generalized time constant are defined for all-pole commensurate fractional order systems. The sufficient condition for stability of these systems in terms of their characteristic ratios is obtained. Also an analytical approach for characteristic ratio assignment (CRA) to have a non-overshooting fast closed ...

Signal-to-noise ratio gain in neuronal systems
Physical Review E, 2001We explore the possibility of a signal-to-noise ratio (SNR) gain both in a single neuron and a neuronal network. In the presence of a weak sinusoidal or pulse signal and Gaussian noise, the output SNR can exceed the input SNR over a wide range of noise intensities. The high output SNR and SNR gain can be acquired coincidentally at optimal noise levels.

Reliable monitoring system for arteriovenous ratio computation
Computerized Medical Imaging and Graphics, 2013The degree of narrowing or widening in retinal vessels related to several cardiovascular diseases such as hypertension or diabetes may be measured by the arteriovenous ratio (AVR), that is, the relation between the artery and vein retinal vessel widths.

Fundamentals of the RL ratio system
1997The RL ratio system25, established by Reichmann/Lachnit26 (1976), represents a further development in the understanding of ratio systems. The RL system was designed for analysis purposes and, moreover, as an aid to management, in order to provide decision-making information within the framework of the planning and control process. As regards managerial

On the damping ratio of multi‐degree‐of‐freedom systems
Communications in Applied Numerical Methods, 1992AbstractThe damping parameter is commonly used when assessing a vibration system or analysing dynamical response, as well as reducing vibration levels. A basic step towards analysing a damped system is to solve its complex eigenvalues. However, the solution is computer‐time‐consuming.

Likelihood ratio gradient estimation for stochastic systems
Communications of the ACM, 1990Consider a computer system having a CPU that feeds jobs to two input/output (I/O) devices having different speeds. Let θ be the fraction of jobs routed to the first I/O device, so that 1 - θ is the fraction routed to the second. Suppose that α = α(θ) is the steady-sate amount of time that a job spends in the system. Given that θ is a decision variable,
