Objective: The first aim of this study is to describe the length, weight, condition factor, and GSI Alburnus istanbulensis (Battalgil, 1941) in two different connected habitats (stream habitat reservoir lake) Karamenderes River, Çanakkale. second state growth type species sampled using length-weight relationship (LWR) model. Materials Methods: sampling areas are Bayramiç Reservoir tributaries o...

We report on the detection in Sloan Digital Sky Survey data of at least three, roughly parallel components in a 65 •-long, stellar stream complex previously identified with the Anticenter or Monoceros Ring. The three-stream complex varies in width from 4 • to 6 • along its length and appears to be made up of two or more narrow substreams as well as a broader, diffuse component. The width and co...

A new method for low complexity image coding is presented, that permits different settings and great scalability in the generation of the final bit stream. This coding presents a continuoustone still image compression system that groups loss and lossless compression making use of finite arithmetic reversible transforms. Both transformation in the space of color and wavelet transformation are re...

Essential to understanding the overall structure of river networks is a knowledge of their detailed architecture. Here we explore the presence of randomness in river network structure and the details of its consequences. We first show that an averaged view of network architecture is provided by a proposed self-similarity statement about the scaling of drainage density, a local measure of stream...

Existing crypto-based Private Information Retrieval (PIR) schemes are either limited in the set of queries they can perform, or have prohibitively large performance overheads in making query comparisons. On the other hand, most previous tamper-resistant hardware schemes can support more general queries and have lower performance overheads, but need to trust that the query program will not leak ...

We consider the problem of approximating the frequency of frequently occurring elements in a stream of length n using only a memory of size m ≪ n. This models the process of gathering statistics on Internet packet streaming using a memory that is small relative to the number of classes (e.g. IP addresses) of packets. We show that when some data item a occurs αn times in a stream of length n, th...

Absrract.-Log length exerted a critical influence in stabilizing large woody debris (LWD) pieces added as an experimental stream restoration technique. Logs longer than the average bank-full channel width (5.5 m) were significantly less likely to be displaced than logs shorter than this width. The longest log in stable log groups was significantly longer than the longest log in unstable groups....

We introduce a new model – the Filter-Combiner model – for memoryless synchronous stream ciphers. The new model combines the best features of the classical models for memoryless synchronous stream ciphers – the Nonlinear-Combiner model and the Nonlinear-Filter model. In particular, we show that the Filter-Combiner model provides key length optimal resistance to correlation attacks and eliminate...
