Opis:
A graph G =(V,E) with p vertices and q edges is said to have skolem difference mean labeling if it is possible to label the vertices x ϵ V with distinct elements f (x) from {1,2,3,…,p+q} in such a way that the edge e =uv is labeled with |f(u)-f(v)|/2 if |f(u)-f(v)| is even and (|f(u)-f(v)|+1)/2 if |f(u)-f(v)| is odd and the resulting labels of the edges are distinct and are from {1,2,3,…,q}. A graph that admits skolem difference mean labeling is called a skolem difference mean graph. In this paper, the author studied the edge reduced skolem difference mean number of some graphs.

Opis:
Let G = (V, E) be a simple connected graph. The induced weak cycle partition of G is defined as the partition of V(G) into subsets such that each subset induces a cycle or K2 or K1. The induced weak cycle number of G, denoted by ρ_wc (G), is the minimum cardinality taken over all induced weak cycle partitions. In this paper, the concept of induced weak cycle number is introduced and induced weak cycle number of path and some of its derived graphs are studied.

Opis:
Numbers of the form (n(3n-1))/2 for all n ≥ 1 are called pentagonal numbers. Let G be a graph with p vertices and q edges. Let f : V(G)→{0,1,2,…,P_q} where P_q is the q^th pentagonal number be an injective function. Define the function f *: E(G) → {1,5,…,P_q} such that f *(uv)=│f(u)-f(v)│for all edges uv∈E(G). If f *( E(G)) is a sequence of distinct consecutive pentagonal numbers {P_1,P_2,…,P_q}, then the function f is said to be pentagonal graceful labeling and the graph which admits such a labeling is called a pentagonal graceful graph. In this paper, pentagonal graceful labeling of some graphs is studied.

Opis:
Numbers of the form n(n+1) are called oblong numbers. Let O_n be the n^th oblong number. An oblong sum labeling of a graph G =(V,E) with p vertices and q edges is a one to one function f : V(G)→{0,2,4,6,8,…} that induces a bijection f^*: E(G)→{O_1,O_2,O_3,…,O_q } of the edges of G defined by f^* (uv)=f(u)+f(v) for all e = uv ∈ E(G). The graph that admits oblong sum labeling is called oblong sum graph. In this paper, oblong sum labeling of some special graphs is studied.

extra skolem difference mean labeling
Opis:
A graph G =(V,E) with p vertices and q edges is said to have skolem difference mean labeling if it is possible to label the vertices x ϵ V with distinct elements f (x) from the set {1,2…p+q} in such a way that the edge e =uv is labeled with |f(u)-f(v)|/2 if |f(u)-f(v)| is even and (|f(u)-f(v)|+1)/2 if |f(u)-f(v)| is odd and the resulting labels of the edges are distinct and are from {1,2…q}. A graph that admits skolem difference mean labeling is called a skolem difference mean graph. If one of the skolem difference mean labeling of G satisfies the condition that all the labels of the vertices are odd, then we call this skolem difference mean labeling an extra skolem difference mean labeling and call the graph G an extra skolem difference mean graph. In this paper, extra skolem difference mean labeling of some graphs are studied.

Opis:
In this work, the pulse electrodeposition technique was employed for the first time to deposit $AgInSe_2$ films. The films were deposited at room temperature from a bath containing Analar grade 10 mM silver sulphate, 50 mM indium sulphate and 5 mM $SeO_2$. The deposition potential was maintained at -0.98 V (SCE). Tin oxide coated glass substrates (5.0 $Ω$/sq) were used for depositing the films. The duty cycle was varied in the range of 6-50%. The X-ray diffraction pattern of the thin films deposited at different duty cycles indicated the peaks corresponding to $AgInSe_2$. The transmission spectra exhibited interference fringes. Resistivity of the films increased from 1.5 $Ω$ cm to 12.4 $Ω$ cm. Mobility increased with duty cycle. Carrier density decreased with duty cycle. The photovoltaic parameters of CdS/$AgInSe_2$ solar cells increased with duty cycle.
