Nuclear shadowing in the structure function F 3 is investigated as a possible test of shadowing models. The F 3 shadowing is studied in two different theoretical models: a parton-recombination model with Q 2 rescaling and an aligned-jet model. We find that predictions in these models differ completely in the small x region. It suggests that the F 3 shadowing could be used for discriminating amo...

This study aimed to compare the effect of teaching metacognitive listening strategies through shadowing activity on the listening comprehension of field-dependent (FD) and field-independent (FI) EFL learners. Since the researcher had access only to female participants,85 female EFL learners from a language institute in Tehran, at the pre-intermediate level of proficiency with the age range of 1...

We define continuous and inverse shadowing for flows and prove some properties. In particular, we will prove that an expansive flow without fixed points on a compact metric space which is a shadowing is also a continuous shadowing and hence an inverse shadowing (on a compact manifold without boundary).

This paper describes measurements which were performed to characterize shadowing in indoor radio environments. The log-normal shadowing model has been traditionally used to characterize the large scale fading component of the received power envelope in mobile and portable radio channels [1,2]. In this research we investigated the suitability of the log-normal shadowing model for indoor radio ch...

We study the genericity of the first weak inverse shadowing property and the second weak inverse shadowing property in the space of homeomorphisms on a compact metric space, and show that every shift homeomorphism does not have the first weak inverse shadowing property but it has the second weak inverse shadowing property.

Cognitive radio network maximizes number of secondary users (SUs) without affecting the service of primary users (PUs). Admittance of SUs is not only affected by the path loss but also lognormal shadowing. In this paper, we have carried out the simulation study of joint admission and power control (JAPC) algorithms: JAPCMRER and JAPC-MSSRA in presence as well as absence of log-normal shadowing....

Shadowing is a method of backward error analysis that plays a important role in hyperbolic dynamics. In this paper, the shadowing by containment framework is revisited, including a new shadowing theorem. This new theorem has several advantages with respect to existing shadowing theorems: It does not require injectivity or differentiability, and its hypothesis can be easily verified using interv...
