Abstract. Displacement monitoring is a critical control for risks associated with potentially sudden slope failures. Instrument measurements are, however, obscured by the presence of scatter. Data filtering methods aim to reduce scatter and therefore enhance performance early warning systems (EWSs). The effectiveness EWSs depends on lag time between onset acceleration its detection system such ...

1.1 Preliminaries A code of length n over the finite field Fq is a subset of V = F n q , and it is linear if it is an Fq-subspace of V . When q = 2 we talk of binary codes and binary linear codes. The weight w(a) of an element a ∈ V is the number of non-zero entries in a. The minimum weight of a linear code C is the smallest number which is a weight of a non-zero element of C. The weight enumer...

It is shown that SBIED(4k 2 , 2Jc 2 ± k, P ± k) and Hadamard matrices with maximal excess exist for qs,q {q:q 1 (mod 4) is a prime power}, + 1, g the length of a Golay sequence}. There a proper n dimensional Hadamard matrix of order (4k2)n. Regular symmetric Hadamard matrices with constant diagonal are obtained for orders 4k2 whenever complete regular 4-sets of regular matrices of order k 2 exist.
