THE EFFECT OF IMMIGRATION ON WAITING TIME PROCESS FOR M/M/1 QUEUEING SYSTEM

THE EFFECT OF IMMIGRATION ON WAITING TIME PROCESS FOR M/M/1 QUEUEING SYSTEM

Since if no new customers arrive during (0, t), then the waiting time reduces to zero at time x. For n > 1, at least one new customer must arrive during (0, x), as otherwise the waiting time will reduce to zero at x< t; let the first new customer arrive at time , where  has the distribution (+K) e –(+K) d (0<<x). If  m is the service time of this customer, then

A Non Preemptive Priority Queueing System with a Single Server Serving Two Queues M/G/1 and M/D/1 with Optional Server Vacations Based on Exhaustive Service of the Priority Units

A Non Preemptive Priority Queueing System with a Single Server Serving Two Queues M/G/1 and M/D/1 with Optional Server Vacations Based on Exhaustive Service of the Priority Units

We study a vacation queueing system with a single server simultaneously dealing with an M/G/1 and an M/D/1 queue. Two classes of units, priority and non-priority, arrive at the system in two independent Poisson streams. Under a non-preemptive priority rule, the server provides a general service to the priority units and a deterministic service to the non-priority units. We further assume that the server may take a vacation of ran- dom length just after serving the last priority unit present in the system. We obtain steady state queue size distribution at a random epoch. Corresponding results for some special cases, including the known results of the M/G/1 and the M/D/1 queues, have been derived.

Spectrum sharing via hybrid cognitive players evaluated by an M/D/1 queuing model

network in which a subset of nodes operates in full-duplex mode is presented in [19]. Compared to [20] and [21], in which an altruistic player can regain access to shared spectrum in an asynchronous ALOHA network, [19] only allows licensed primary users to access the network. In order to evaluate our game theory modeling approach, we used a queuing analysis that is used in [22]. The opportunistic access used for the performance analysis in [22] does not consider different cost functions or pric- ing schemes, number of primary or secondary cognitive users, or congestion. An M/G/1 queuing system (a queue model in which arrivals are Markovian and service times have a general distribution with a single server) containing one primary and multiple secondary users is presented in [23]. Here, we use an M/D/1 queuing system, merely to be used for analysis. Secondary users can gain access to the spectrum through an amplify-and-forward time-division multiple-access protocol. Our method is more general- ized in that it supports multiple primary users as well as general cost functions that are not imposing any perfor- mance requirement for secondary users such as amplify and forward.

end of the sojourn time in state i, a transition takes place to another state or to the same state. The transition may or may not correspond to an arrival. Let us consider the simple case of two-state MMPP, also known as MMPP(2) system, where the arrival rate, λ i (i=1, 2) appears alternately with exponentially distributed life time, r i − 1 (i=1, 2). These are shown in Fig. 1 where the transition between level-1 and level-2 occurs without any arrival. The two-state MMPP is characterized by the matrix pair (Q, D), where Q is the infinitesimal generator matrix and D is the arrival matrix. Here, both Q and D are 2 × 2 square matrices. The generator matrix Q, is expressed as the sum of matrix D and another matrix C; all the off-diagonal elements of C and all the elements of D are nonnegative but the diagonal elements of C are negative:

The gender dimension of the Spanish social protection system (1978 1996)

The gender dimension of the Spanish social protection system (1978 1996)

Nevertheless, the conflicts between trade unions and the government had no visible effects in govemability15 and further liberalising economic measures were still being adopted, as well as the progress towards the professional character o f the system. This was possible because union pressure aimed at attenuating the consequences o f these policies to the central core o f workers, maintaining a relatively reduced number o f first order social risks. The groups that were affected most by the liberalising measures were those whose interests were not represented by any o f the social and political partners involved in the process. Therefore, from a gender point o f view, the opposition o f trade unions to the governmental reforms was relative. The design o f the social protection system that came under the 1985 reform was never really challenged by trade unions because it did not damage the expectations o f their most solid clientele. Social security consolidated specific circuits o f distribution, as a sort o f what Ferrera (1996) calls ‘welfare clientelism’. As for the employers’ organisation, the CEOE, even when it was not actively involved in policy reform, it has prioritised private market solution to chronic social security problems, far less attention being paid to the peripheral labour market in which Spanish women are over-represented.

Qualitative In this paper the terms d-system, m-system, n-system, U-ternary semigroup are introduced. It is proved that an ideal A of a ternary semigroup T is a prime ideal of T if and only if T\A is an m-system of T or empty. It is proved that an ideal A of a ternary semigroup T is completely semiprime if and only if T\A is a d-system of T or empty. It is proved that every m- system in a ternary semigroup T is an n-system. Further it is proved that an ideal Q of a ternary semigroup T is a semiprime ideal if and only if T\Q is an n-system of T (or) empty. It is proved that if N is an n-system in a ternary semigroup T and a  N, then there exist an m-system M in T such that a  M and M  N. It is proved that a ternary semigroup T is U-ternary semigroup if and only if every ideal A of T is semiprime ideal of T. Further it is proved that if T is a ternary semigroup and A is an ideal of T, then T is U-ternary semigroup if and only if T\A is an n-system of T or empty and if T is U-ternary semigroup and A is an ideal of T, then T\A is an m-system of T.

In an acoustically and electrically shielded room where the subjects were seated comfortably in a reclining chair, the EEG data were obtained from 16 surface electrodes placed on the scalp according to the standard international 10/20 system, namely the 16 channels, Fp1, Fp2, F3, F4, F7, F8, C3, C4, P3, P4, T3, T4, T5, T6, O1, O2 with reference to linked earlobes. The digitization of 16 channels EEG was performed with a sampling rate of 100Hz using a 12 bit AD- converter and the data were recorded on a hard disk. For each subject, recordings covered the EEG activity of a resting condition for time ranging from 3 to 5 minutes approximately.

Counting 4×4 matrix partitions of graphs

Counting 4×4 matrix partitions of graphs

Hell, Hermann and Nevisi’s dichotomy [8, Theorem 10] shows that if M is a symmetric impure 3 × 3 matrix then #M -partitions is #P-hard if M contains ( ∗ ∗ ∗ 0 ) or ( ∗ ∗ ∗ 1 ) (or any permutation of these) as a principal submatrix. Otherwise, #M -partitions is in FP. We will now show that this result is consistent with Conjecture 10, which we have already shown to be equivalent to Conjecture 2. In one direction, if M contains one of these hard principal submatrices then the rows and columns of this hard principal submatrix are an M-derectangularising sequence, so Conjecture 10 also says that M is hard. In the other direction, if M does not contain one of these hard principal submatrices then the following lemma shows that M has no derectangularising sequence, so Conjecture 10 also says that M is easy.

respectively. The retrial is introduced for low priority customers only. The server goes for vacation after exhaustively completing the service to both types of customers. The vacation rate follows an exponential distribution with parameter α. The concept of vacation interruption is used in this paper that is the server comes from the vacation into normal working condition without completing his vacation period subject to some conditions. Let k be the maximum number of waiting spaces for high priority customers in front of the service station. The high priority customers will be governed by the pre-emptive priority service. We assume that the access from orbit to the service facility is governed by the classical retrial policy. This model is solved by using Matrix geometric Technique. Numerical study have been done for Analysis of Mean number of low priority customers in the orbit (MNCO), Mean number of high priority customers in the queue (MPQL), Truncation level (OCUT), Probability of server free and Probabilities of server busy with low and high priority customers and probability of server in vacation for various values of λ 1 , λ 2 , μ 1 , μ 2 , α

On rationality of nonnegative matrix factorization

On rationality of nonnegative matrix factorization

Nonnegative matrix factorization (NMF) is the problem of decomposing a given nonnegative n × m matrix M into a product of a nonnegative n × d matrix W and a nonnegative d ×m matrix H. NMF has a wide variety of applications, in- cluding bioinformatics, chemometrics, communication com- plexity, machine learning, polyhedral combinatorics, among many others. A longstanding open question, posed by Cohen and Rothblum in 1993, is whether every rational matrix M has an NMF with minimal d whose factors W and H are also rational. We answer this question negatively, by exhibiting a matrix M for which W and H require irrational entries.

In contrast to the meteorological variables measured in this paper, the soil hydrological regime was greatly affected by the flood irrigation, as revealed in Figure 4. Daily θ values registered similar patterns to the GWD data, exhibiting a decrease with an increase in GWD over the passage of time during the growing season, which in fact, showed a sudden increase after the flood irrigation. In the vertical profile, the values of θ exhibited an increase with increasing depths (Figure 4a), while the electrical conductivity (EC, mS cm −1 ) varied in agreement with θ data, which also appeared to be
