many genetic disorders or possible abnormalities that may occur in the future generations can be predicted through analyzing the features of the chromosomes. for this purpose, karyotype is often used which to make it, there is necessary to identify each one of the 24 chromosomes from the microscopic images. the first step of this process is to define the morphological and band pattern based fea...

Big Bang Nucleosynthesis (BBN) represents a key subject of modern cosmology since it is a powerful tool to study fundamental interactions. In the recent years, the improvement on the measurement accuracy of light primordial nu-clei abundances allowed BBN to enter in a sort of precision era. In view of this, a great theoretical effort has been devoted to make theoretical predictions comparably a...

Given a vector of floating-point numbers with exact sum s, we present an algorithm for calculating a faithful rounding of s into the set of floating-point numbers, i.e. one of the immediate floating-point neighbors of s. If the s is a floating-point number, we prove that this is the result of our algorithm. The algorithm adapts to the condition number of the sum, i.e. it is very fast for mildly...

With the increasing popularity of a E-mail users, E-mail spam problem growing proportionally. Spam filtering with near duplicate matching scheme is widely discussed in recent years. It is based on a known spam database formed by user feedback which cannot fully catch the evolving nature of spam and also it requires much storage. In view of above drawbacks, we proposed an effective spam detectio...

We report late-time observations of the radio afterglow of GRB 030329. The light curves show a clear achromatic flattening at 50 days after the explosion. We interpret this flattening as resulting from the blast wave becoming transrelativistic. Modeling of this transition enables us to make estimates of the energy content of the burst, regardless of the initial jet structure or the distribution...

Yehea I. Ismail Department of Electrical and Computer Engineering Northwestern University Evanston, IL. 60208 Abstract A method is introduced to evaluate time domain signals witbin RLC trees with arbitrary accuracy in response to any input signal. This method depends on finding a low frequency reduced order transfer function by direct truncation of the exact transfer function at Merent nodes of...

Most process models calibrate their internal settings using historical data. Collecting such data collection is an expensive, tedious, and often incomplete process. Hence, we seek an alternative to calibration from historical data. Formally, historical data offers constraints to a set of model options. An alternative methods of generating those constraints is to augment a process model with a s...

We enlarge our set of supersymmetric models and update accelerator constraints in our precise calculation of the relic density of the lightest neutralino, which includes relativistic Boltzmann averaging, subthreshold and resonant annihilations, and coannihilation processes among charginos and neutralinos.
