Böbrek taşlarının medikal görüntülerdeki teşhisi ve tespiti hastalığın seyri tedavi yönteminin belirlenmesi açısından önemlidir. Abdominal Bilgisayarlı Tomografi (BT) görüntülerinin gürültülü düşük çözünürlükte olması böbrek taşı teşhisini zorlaştıran faktörlerdir. Bu çalışmada abdominal BT görüntülerinde bulunan böbreklerdeki taşların sınırlarının sayılarının amaçlanmıştır. İlk olarak netleşti...

This paper presents the use of polymer coated microelectrodes for the realtime conductivity monitoring in a microchannel photoablated through the polymer without contact. Based on this strategy, a small conductometry sensor has been developed to record in time conductivity variation when an enzymatic reaction occurs through the channel. The rate constant determination, k2, for the dephosphoryla...

A semiautomatic procedure is presented for the separate determination of total T3 and T4 in serum in approximately 10 hrs simultaneously in 25 samples. Removal of the thyroid hormones from the serum, separation of T3 from T4 and concentration of the peaks were achieved in a closed system, consisting of three consecutive columns. The automatic microchemical iodine determination of T3 and T4 resp...

Abstract We consider the problem of estimating a cloud points from numerous noisy observations that after unknown rotations and possibly reflections. This is an instance general estimation under group action, originally inspired by applications in three-dimensional imaging computer vision. focus on regime where noise level larger than magnitude signal, so much cannot be estimated reliably. prop...

In this study, the effect of speech-intrinsic variabilities such as speaking rate, effort and speaking style on automatic speech recognition (ASR) is investigated. We analyze the influence of such variabilities as well as extrinsic factors (i.e., additive noise) on the most common features in ASR (mel-frequency cepstral coefficients and perceptual linear prediction features) and spectro-tempora...

Studies on the circadian rhythm of conidiation in the bd strain of Neurospora crassa Shear and Dodge have shown that temperature step-up and step-down perturbations produce phase advances and delays, respectively. Pulse-up and pulse-down treatments lead to both phase advances and delays. The resulting phase shifts can be very large, and few to no transients are observed.Small amplitude temperat...

We simulated the dynamics of the Pi-Puppid meteoroid stream. The evolution of such a short period stream is dominated by close encounters with Jupiter. The effect is so great that it can cause the stream to split into several parts and form gaps. The difference in period of each part leads to the possibility of a meteor outburst on Earth while the parent body is at aphelion. Past observations a...

In this study, the IWA anaerobic digestion model N°1 (ADM1) was used to simulate and predict the dark fermentation process of a complex organic substrate: household waste. Since ADM1 does not account for metabolic products such as lactic acid, ethanol and some volatiles fatty acids like caproate, that appear during the dark fermentation process, the structure of ADM1 was modified to include the...

Frequently the activity of fresh catalyst changes with time in use. The decrease or increases of the catalyst activity with time during the course of reaction forces the system to an unsteady state operation ([1], [2], [3], [4] and [5]). One of these catalysts is the copper/zinc oxide catalyst, which is industrially used for methanol production. The activity of copper/zinc oxide catalyst declin...
