Özet Bu araştırmada, matematik öğretmen adaylarının matematiğin önemli bir konusu olan " Limit " hakkındaki kavramsal yapılarını belirlemek amaçlanmıştır. Araştırmaya bir devlet üniversitesinde eğitim gören 152 matematik öğretmen adayı katılmıştır. Ölçme aracı olarak Kelime İlişkilendirme Testi kullanılmıştır. " Limit " anahtar kavramı Kelime İlişkilendirme Testi ile öğretmen adaylarına sunulmuştur. Toplanan verilerden frekans tablosu elde edilmiş olup buna göre kesme noktası tekniği kullanılarak öğretmen adaylarının anahtar kavrama ilişkin kavramsal yapılarını gösteren kavram ağları çizilmiştir. Araştırma sonucunda öğretmen adaylarından limit anahtar kavramına ilişkin toplamada 87 cevap kelime elde edilmiş olup 18 kategori oluşturulmuştur. Oluşturulan kategorilerden 60 ve üzeri frekansta ilişkilendirmenin yapılmış olduğu " Sınırlılık, Yakınsaklık, Belirsizlik, Süreklilik, Sonsuzluk, Türev, Fonksiyon ve Sağ-Sol Limit " kategorileri daha dikkat çekici görülmektedir. Sonuç olarak başka matematiksel kavramlarla da çalışılarak öğrencilerin zihinlerindeki kavramsal yapıların ortaya konması önerilmektedir.

We consider a simple random walk (dimension one, nearest neighbour jumps) in a quenched random environment. The goal of this work is to provide sufficient conditions, stated in terms of properties of the environment, under which the Central Limit Theorem (CLT) holds for the position of the walk. Verifying these conditions leads to a complete solution of the problem in the case of independent identically distributed environments as well as in the case of uniformly ergodic (and thus also weakly mixing) environments.

Purpose of this research is to evaluate vehicle driver especially four wheel vehicle to know driver criteria on speed limit, especially on four wheel vehicle. This research takes the route from Surabaya to Jombang across toll road. This research is conducted with counting each vehicle speed with looking on speed standard on the respective road. The result shown that majority of the driver still not care about speed limit, but driver still care only for the speed not for their safety. For dominant speed is around 80 – 100 km/hour. In this research also counts driver perception percentage that caused by driver who surpass the determined limit or below the limit. It could be concluded that by motoric behavior, we will decide to overspeed or obey the rules that shown by speed limit sign that also has an effect and driver perception on driving affect to driver situation before or while on trip using vehicle.

We present a method to include colour-suppressed effects in the Mueller dipole picture. The model consistently includes saturation effects both in the evolution of dipoles and in the interactions of dipoles with a target in a frame-independent way. When implemented in a Monte Carlo simulation together with our previous model of energy-momentum conservation and a simple dipole description of initial state protons and virtual photons, the model is able to reproduce to a satisfactory degree both the γ * p cross sections as measured at HERA as well as the total pp cross section all the way from ISR energies to the Tevatron and beyond.

We obtain exponential upper bounds for tails of distributions of generalized L-statistics based on a sample from an exponential distribution. We prove the asymptotic normality of generalized L-statistics based on a sample from the uniform distribution on [0,1] and of L-statistics with decomposed kernels (without any restrictions on the sample distribution type).
