Memory-Efficient Key/Foreign-Key Join Size Estimation via Multiplicity and Intersection Size

2021 IEEE 37th International Conference on Data Engineering (ICDE), 2021
Join size estimation plays a crucial role in query optimization. In this paper, we present a technique to estimate the size of a key/foreign-key join of two filtered relations. We build on a model by Allen Van Gelder, in which there is no notion of join selectivity.

Particle size: the key to the atherogenic lipoprotein?

QJM, 1994
Using different analytical methods, up to 12 low-density lipoprotein (LDL) subfractions can be separated. LDL particle size decreases with increasing density. Smaller, denser LDL particles seem more atherogenic than the larger, lighter particles, based on the experimental findings that smaller LDL particles are more susceptible for oxidation in vitro ...

Designing Touch Screen Numeric Keypads: Effects of Finger Size, Key Size, and Key Spacing

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1997
Designing numeric keypads for point-of-sale devices to optimize keying speed and accuracy while efficiently utilizing touch screen real estate is a challenge. Existing design guidelines for touch screens are applicable to only specific classes of devices and fail to consider user variables such as finger size.

Square Hash with a Small Key Size [PDF]

, 2003
This paper shows an improvement of square hash function family proposed by Etzel et al. [5]. In the new variants, the size of keys is much shorter while the collision probability is slightly larger. Most of the main techniques used to optimize the original square hash functions work on our variants as well.

Slim Size Card Key Development

2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012
Key being used to identify & allow door access and engine start has been developed to the possibility of integration into the cellular phone with the help of increased electronics and wireless communication skill. But even all electrical function can replace conventional ones, it still need mechanical key blade for the case of emergency situation. From

Choosing key sizes for cryptography

Information Security Technical Report, 2010
After making the decision to use public-key cryptography, an organisation still has to make many important decisions before a practical system can be implemented. One of the more difficult challenges is to decide the length of the keys which are to be used within the system: longer keys provide more security but mean that the cryptographic operation ...

Size, age and innovativeness: Key determinants of growth?

2012 IEEE International Conference on Management of Innovation & Technology (ICMIT), 2012
Young Innovative Companies (YIC) gained increasing attention from governments and scholars due to their expected high innovative performance and growth. Consequently, this study investigates whether Young Innovative Companies, as defined by the EU, grow more than other firms, both in terms of employment and in terms of sales.
