N-ARY POLYGROUPS
Polygroups are multivalued systems that satisfy group like axioms. In this paper the class of n-arypolygroups is introduced. The concepts of n-ary normal subpolygroups and strong homomorphisms of n-arypolygroups are adopted. With respect to these concepts the isomorphism theorems for n-ary polygroups arestated and proved. Finally, we will consider the fundamental relation * defined on an n-ary polygroup andprove some results in this respect.

ALMOST CONVERGENCE THROUGH THE GENERALIZED DE LA VALLÉE-POUSSIN MEAN
Lorentz characterized the almost convergence through the concept of uniform convergence of de laVallée-Poussin mean. In this paper, we generalize the notion of almost convergence by using the concept ofinvariant mean and the generalized de la Vallée-Poussin mean. We determine the bounded linear operators forthe generalized σ-conservative, σ-regular and σ-coercive matrices.

ON A SPECIAL CLASS OF FINSLER METRICS
In this paper, we study projective Randers change and C-conformal change of P-reduciblemetrics. Then we show that every P-reducible generalized Landsberg metric of dimension n 2 must be aLandsberg metric. This implies that on Randers manifolds the notions of generalized Landsberg metric andBerwald metric are equivalent.

A CLASS OF LIFT METRICS ON FINSLER MANIFOLDS
In this paper, we are going to study the g-natural metrics on the tangent bundle of Finslermanifolds. We concentrate on the complex and Kählerian and Hermitian structures associated with Finslermanifolds via g-natural metrics. We prove that the almost complex structure induced by this metric is acomplex structure on tangent bundle if and only if the Finsler metric is of scalar flag curvature. Then we showthat the complex structure is Hermitian if and only if the Finsler metric is of constant flag curvature.

THE INVOLUTE-EVOLUTE OFFSETS OF RULED SURFACES
In this study, a generalization of the theory of involute-evolute curves is presented for ruledsurfaces based on line geometry. Using lines instead of points, two ruled surfaces which are offset in the senseof involute-evolute are defined. Moreover, the found results are clarified using computer-aided examples

DESIGN AND CONSTRUCTION OF A HIGH PRECISION TAC
TAC (Time to Amplitude Convertor) is one of the most important time measurement instrumentswhich has great significance in many fields of science, especially radiation physics. A TAC unit has beendesigned based on the START-STOP analog method and NIM (Nuclear Instrument Modules) standards. Afterdesigning the circuit, it was simulated by PSPICE software and constructed by discrete and integratedcomponents. Accuracy of performance, linearity and time resolution of the TAC were checked in laboratorycondition and a neutron-gamma discrimination experiment was carried out using this TAC. Results of theseexperiments and the spectrum of neutron-gamma discrimination completely agree with those from othersimilar TACs, and are, to some extent, better.
