Solar energy is the least polluting and most inexhaustible of all known energy sources. The sun bathers the earth with more energy each minute then the world consumes in one year. In Malaysia, the sun intensity does not vary by season. It is a suitable place to develop the solar cell system. To make solar energy more efficient, the solar panel syst

يركز هذا البحث في بيان أهم كتب البيان النبوي من حيث اللغة والشرع، مع إيضاح ما فيها من اسرار اللغة من البلاغة والبيان البديع، ومن ثم يهتم البحث بذكر معاني البيان وما يدل عليه، وأقسامه، وسرد بعض �

Islamic institutions of higher learning are keeping abreast in developing their students for future leadership. However, few empirical investigations have been conducted thus giving impetus to this research. The main purpose of this study is to explore the leadership experiences and practices of undergraduate student leaders on their involvement as

We study the phase diagrams for the Potts model on the Bethe lattice with competing nearest-neighbor interactions J1 and ternary interactions Jp and Jt: At vanishing temperature, the phase diagram is fully determined for all values and signs of Jp=J1 and Jt=J1; in particular, we show that the phase diagrams contain ferromagnetic, paramagnetic and &

We study an Ising model on a general Cayley tree with competing interaction of next-nearest-neighbour of two types; prolonged and one-level k-tuple interactions. Vannimenus covers a study of Ising model on competing nearest-neighbour interaction J1 and prolonged next-nearest-neighbour interaction Jp. Later Mariz et al extend Vannimenus work by addi

We study the phase diagram of the Ising model on a Cayley tree with competing prolonged next-nearest neighbour Jp and one-level next-nearest neighbour interactions J0. Vannimenus proved that the phase diagram of Ising model with competing neareast-neighbour interaction J1 and prolonged next-nearest neighbour interactions Jp contains a modulated pha

We study the phase diagram of the Ising model on a Cayley tree with competing prolonged next-nearest neighbour Jpand one-level next-nearest neighbour interactions J. Vannimenus proved that the phase diagram of Ising model with competing neareast-neighbour interaction J1and prolonged next-nearest neighbour interactions Jpcontains a modulated phase,

G.D Birkhoff characterized the set of extreme doubly stochastic matrices. Namely his result states as follows: the set of extreme points of the set of doubly stochastic matrices coincides with the set of all permutations matrices. One can consider a generalization of Birkhoff's result for nonlinear doubly stochastic operators. Among all nonline

Titanium alloys are widely known as difficult to cut materials, especially at higher cutting speeds, due to their several inherent properties. Siekmann [1] suggested that machining of titanium and its alloys would always be a problem, no matter what techniques are employed to transform this metal into chips. When machining Ti-6Al-4V, conventional t
