... statistical analysis of the capacity of N∗Nakagami-m channels. Specifically, we have studied the influence of the severity of fading and the number of hops on the PDF, CDF, LCR, and ADF of the channel capacity. ... levels r. Furthermore, the variance of the channel capacity decreases by increasing the number of hops, while increase in the severity of fading...

... the electronic journal of combinatorics 4 (1997), #R19 2 Theorem. For all graphs G α(G) = min{ rank(B) |B ∈B(G)} implies α(G)= χ(G). Proof. Let S = {v 1 ,v 2 , ,v α(G) } be the stable set of ... ≤|(u\v)∪(v\u)|≤5 for all u, v ∈ V (G). Then [5] χ(G) = 32 and rank(A(G)) = 29 where A(G) is the adjacency matrix of G. Then χ(G)=32and the electronic journal of combinatorics 4 (1997),...

... one colouring they have different colours and with the same colour in the other one. Let us denote r k as the number of different strict colourings of H using k colours; we will call the vector R(H)=(0, ... all the blocks are at the same time C-edges and D-edges [8]. In [8, 9, 10] the necessary conditions for the existence of strict colourings for BSQSswere determined and...

... Suppose that there exists the right unit element e 2 of the operation of the generalized convolution (11) in the space of functions in L(R + ): f(x) ≡ (f γ ∗ e 2 )(x), ∀x>0. Therefore F (f γ ∗ ... 4. In the space of functions belonging to L(R + ) the operation of the generalize d convolution (11) does not have the unit element but the left unit element e 1 = −i...

... α(j) = 0, 0 ≤ j ≤ n. Then the solution of (4.4) and (4.5) is bounded if and only if the condition (5.5) is satisfied. Proof. The proof is immediate consequence from proof of Theorem 4.3 with Remark ... condition for the boundedness of all solutions of (1.1) and the scalar case of (1.1), respectively. The next result provides a sufficient condition for the boundedness of...

... Figure 4 . The peaked- ness of the out -of- band signal exceeds the peakedness of the in-band signal by over an order of magnitude. The lower panel of Figure 5 shows, for the same examples, the total ... the response of the DoL circuit equals that of an RC inte- grator with RC = τ. Otherwise, the output has a smaller absolute rate of ch ange than the abso...
