چکیده
j, 1 i 2n, 1 j 2n, where J2n is the 2n by 2n matrix of all entries 1. It is known that symmetric Bush–type Hadamard matrices exist for all orders 16n2 for all values of n for which there is a Hadamard matrix of order 4n, see [8] for details. A balanced generalized weighing matrix BGW ν κ λ over a group G is a matrix W wi j of order ν , with wi j G 0 such that each row and column of W has κ non–zero entries and for each k

A class of Siamese twin Menon designs
A {0,±1}-matrix S is called a Siamese twin design sharing the entries of I, if S = I +K − L, where I,K,L are non-zero {0, 1}-matrices and both I + K and I + L are incidence matrices of symmetric designs with the same parameters. Let p and 2p−1 be prime powers and p ≡ 3 (mod 4). We describe a construction of a Siamese twin Menon design with parameters (4p, 2p − p, p − p), yielding a Siamese twin...
متن کاملA series of Siamese twin designs intersecting in a BIBD and a PBD
Let p and 2p − 1 be prime powers and p ≡ 3 (mod 4). We describe a construction of a series of Siamese twin designs with Menon parameters (4p, 2p − p, p − p) intersecting in a derived design with parameters (2p − p, p − p, p − p − 1), and a pairwise balanced design PBD(2p − p, {p, p − p}, p − p − 1). When p and 2p − 1 are primes, the derived design and the pairwise balanced design are cyclic. Fu...
متن کاملSigNet: Convolutional Siamese Network for Writer Independent Offline Signature Verification
Offline signature verification is one of the most challenging tasks in biometrics and document forensics. Unlike other verification problems, it needs to model minute but critical details between genuine and forged signatures, because a skilled falsification might only differ from a real signature by some specific kinds of deformation. This verification task is even harder in writer independent...
متن کاملThe Study of different rations of spawning efficiency of siamese fighting fish (Bettasplendens)
The effects of five different foods including: blood worm, artemia cyst, Artemia mass powder, gammarus mass powder and ordinary commercial food were studied on Siamese fighting fish (Bettasplendens) propagation efficiency during thirty days in a Randomize Totally Design with 4 repeats .Experimental plots had been consisted of twenty 30*30*40 (cm) aquarium which a pair of male and female brood s...
متن کاملPreliminary investigation of Boltzmann machine classifiers for speaker recognition
We propose a novel generative approach to speaker recognition using Boltzmann machines, a fledgeling non-Gaussian probabilistic framework that is increasingly gaining attention in several machine learning fields. We show how a modified i-vector representation of speech utterances enables the development of several Boltzmann machine architectures for speaker verification and we report some preli...
