Strongly Regular Graphs with Parameters ( 4 m 4 , 2 m 4 + m 2 , m 4 + m 2 , m 4 + m 2 ) Exist for

Using results on Hadamard difference sets, we construct regular graphical Hadamard matrices of negative type of order 4m for every positive integer m. If m > 1, such a Hadamard matrix is equivalent to a strongly regular graph with parameters (4m, 2m +m, m +m, m +m). Strongly regular graphs with these parameters have been called max energy graphs, because they have maximal energy (as defined by ...

M m m Queue with Balking, Reneging and Additional Servers

In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...

M M m K Queue With Additional Servers and Discouragement (RESEARCH NOTE)

Waiting in long queue is undesirable due to which in some practical situations customers become impatient and leave the system. In such cases providing additional servers can reduce long queue. This investigation deals with multi-server queueing system with additional servers and discouragement. The customers arrive in poisson fashion and are served exponentially by a pool of permanent and addi...

(E)-N′-(4-Meth­oxy­benzyl­idene)-2-m-tolyl­acetohydrazide

In the title mol-ecule, C17H18N2O2, the benzene rings form a dihedral angle of 83.0 (7)°. In the crystal, N-H⋯O hydrogen bonds, in an R(2)2(8) graph-set motif, link mol-ecules into centrocymmetric dimers, and weak C-H⋯π inter-actions further link these dimers into columns in [100].
