In this research work, the possibility of semi industrial production of Al-TiB2 and Al-ZrB2 composites, using reactive slag in a flame furnace have been investigated. For this purpose, commercial pure aluminum and powder mixture of TiO2 (ZrO2) , KBF4 and Na3AlF6 were used. The results showed that using a proper ratio of slag forming materials as well as proper amounts of the above-mentioned com...

Literature and culture are two inseparable issues. When we talk about the culture, the literature can also appear unconsciously, because the culture is composed of thoughts, feelings and emotions and the styles and personal ways of society, which as a general rule, can appear in terms of principles and respectful rules. The literature on the other hand, discloses and transmits these concepts to...

The aim of this paper is to study the (clinical) time-series data of three diseases with complex dynamics: Parkinson’s disease, Huntington’s disease and Amyotrophic Lateral Sclerosis. For this purpose, first all of the time series data are embedded in a vector space of suitable dimension and then the correlation dimension of the above mentioned diseases is estimated. The results are also compar...

− A mobile ad hoc network represents a state of system dynamics where the topology changes rapidly. This is further complicated with the necessity of real world mobility abstraction, represented by mobility models. The other major players in this system are wireless links, often supplemented by limitations in terms of bandwidth, link breakage, etc. With the above mentioned characteristics, it a...

Spontaneous, idiopathic urinary bladder rupture is a very rare disease entity, which may face the problem of proper preoperative diagnosis. In many cases the medical history, physical examination, and additional tests raise false suspicion of gastrointestinal perforation. The study presented a case of a female patient with spontaneous urinary bladder perforation, paying particular attention to ...

We consider the half-linear second-order difference equation Δ rkΦ Δxk ckΦ xk 1 0, Φ x : |x|p−2x, p > 1, where r, c are real-valued sequences. We associate with the above-mentioned equation a linear second-order difference equation and we show that oscillatory properties of the abovementioned one can be investigated using properties of this associated linear equation. Themain tool we use is a l...

In this paper we consider four versions of Kovarik’s iterative orthogonalization algorithm, for approximating the minimal norm solution of symmetric least squares problems. Although the theoretical convergence rate of these algorithms is at least linear, in practical applications we observed that a too large number of iterations can dramatically deteriorate the already obtained approximation. I...

The ab oscillations in absorbing matter are considered. The standard model based on optical potential does not describe the total ab transition probability as well as the channel corresponding to absorption of the b-particle. We calculate directly the off-diagonal matrix element in the framework of field-theoretical approach. Contrary to one-particle model, the final state absorption does not t...
