The following problem is seriously tricky and I urgently need help with it, thanks. For part a: we have the following transition probability matrix P = a0 a1 a2 a3 a0 a1 a2 a3 0 a0 a1 b2 0 0 a0 b1 Now, is a0 = a1 = a2 = a3 =...

Imagine you are in the universe of the Expanse book. First of all, you want to speed up your spaceship to reach the alien gate. And you will use Jupiter's gravity. But there is a queue of spaceship wanting to go to the gate, and they all use Jupiter's gravity to accelerate. Suddenly Jupiter...

Summary:: I have recently started with data structures in java and I tried doing this Program .But I have few confusions. 1.How do I write the main() of the program? 2.What are we supposed to do with the value returned by function pop()? If anyone could point out if there are any errors and...

So far, I have implemented the code below, using Java Priority Queues and Maps. I tried to identify each customer by the time they came in (ranging from 360 and onwards) and their grades. However, this is my first time using priority queues and maps, and I am not very sure if I'm doing things...

This is my funny theory (may be I have found already known things...).Let us assume the following abstract situation. We have a special place where people can get some kind of service (for instance any bureaucratic office). There is only one service clerk who spend a fixed time (we will call it...

Dear colleagues. I have a difficulty in calculating waiting time of the first packet arriving in a buffer using aggregation. Arrival follow Poisson process with rate lambda and the aggregation is done for a maximum 'm' packets or with the expiry of timer T_maximum. Can anyone help me how to...

hi, initially when I saw these statements , I got really amazed, and now I endeavor to find the proofs of these statements, bu I would like assure you of the fact that there are very very very few sources which evaluate M/G/K or M/G/infinite queue, mostly sources prefer to handle the subject of...

Homework Statement Explain and compare two efficient implementations of a priority queue using binary tree. Ilustrate this on an example of ascending priority queue that is created when elements 15, 38, 45, 21, 8, 55,20 are inserted and the two largest elements are deleted. Homework Equations...

Hello guys! I am learning a bit on queue theory in one of my courses, and decided to try and do some simulations even though it is not mandatory. (Curriculum only covers the steady state, where it can be treated mathematically with ease). Im looking at a birth-death process, where the time til...

Hi, I'm working through a question where I need to design the Deque data abstraction giving it's formal specification with axioms. A deque is a queue where items can be added to and remove from either end of the queue. I've already got an abstraction for a normal queue and from what I can see...

People queuing to pick up photos at an event. They have a bar-coded docket. By scanning the docket, printing is initiated on one of eight printers. Each printer takes 40 seconds to print a photo - the software chooses the least heavily loaded print queue - or uses a round-robin approach if print...

Hi! (Wave) I am looking at the operations of a static queue. pointer MakeEmptyQueue(void) pointer Q; /* temporary pointer */ Q = NewCell(Queue); /* malloc() */ Q->Front = 0; Q->Length = 0; return Q; I have to find the complexity of the above...

[b]1. Encountered with cue to a massive billiards ball, which is initially at rest, see figure uploaded. The ball has radius R and mass M. The queue hits with force F horizontally into the bale height h above the table, and the shock lasts a very short time Δt. It is reported that the moment of...

I’m trying to find out the largest number of cores that can be used on a specific queue in LSF with the bqueues command. I’ve used the option –l after reading the manual, but I don’t see any information about cores listed. Any suggestions? Thanks.

Homework Statement OK I am dealing with a Queue type problem that is M/M/2. I have already solved most of the problem but I can not figure out how to solve for ∏0, Lq, L, & W. The information I am given is: λ=11.98, μ=7 and s=2. Homework Equations The Attempt at a Solution I am...

Homework Statement For an M/M/1 queuing system with the average arrival rate of 0.4 min^−1 and the average service time of 2 minutes, compute A- the expected response time in minutes; B- the fraction of time when there are more than 5 jobs in the system; C- the fraction of customers who...

Homework Statement Its a lot but here is the assignment: You are going to implement an event driven simulation of a priority queue serving a printer. Each job will have one of 5 priorities: enum Priority { development, client, preferred, highest, scheduled }; The printer will be assumed...

Homework Statement You want to process x units of a product (at y processing plants), minimizing the total time spent processing all the units. Each place y_i has a queue of q_i units ahead of you and a processing rate of r_i units/minute. If you can simultaneously process units at the same...

Ernie is always keen to go to the Family on Saturday nights and usually arrives around 11pm. On a particular night, Bert decides to start drinking early and he is already inside the Family while Ernie is on his way. Ernie has noticed over time that the expected number of people in the queue to...

Hi everyone, I am trying to solve this problem but I am stuck with doubts. Here are my ideas. Homework Statement Busloads of customers arrive at an infinite server queue at a Poisson rate λ Let G denote the service distribution. A bus contains j customers with probability aj = 1...

Can someone explain how the function queue::store(int i) (see attachment) works for a sequence of calls to it. Or give a reference to something or give a diagram, please. Doesn't each instant (i.e., each memory location) have its own head, tail and next pointers as well as as the data member...

Homework Statement Customers arrive to a register as a poisson process with arrival rate λ and are serviced with an exponential distribution with service rate μ. When a customer arrives he'll decide to join the line or not depending on how many people are currently in the system (not including...

Homework Statement Given an M/M type queuing model on an first come first save basis, where 2 kinds of customers (type 1 and type 2) arrive as poisson processes with arrival rate λ1 and λ2 respectively, being served by one cashier with timewise exponential distribution with parameter μ...

So, my teacher comes to the lecture, writes the notes on the board... and then says: "from now on this part is intuitive"... he means this part: (myFront != (myBack + 1) % max) of the following (C++) code:- void Queue::addQ (int x) { if (myFront != (myBack + 1) % max) { ...

Hi, I am trying to assign a distribution to the the rate at which passengers enter a queue over a period of time. The period of time is to remain constant. Passengers start arriving 4 hours before a flight and stop arriving at the scheduled time of departure. I have been using a Weibull...

Just watching the live feed from the LHC and as if the black hole it was meant to create was speaking to us, it broke on queue. Seriously..is this thing not the biggest piece of junk ever invented? Obviously it is complicated beyond the scope of this forum..but with scientists studying it for...

Homework Statement All I need is an explanation as to why the algorithm I've been given doesn't destroy the queue properly. When I use the code below, and I check if q is NULL or not, it says it isn't, and I'd like to know why. Thanks :)Homework Equations None, this is computer science...

Hello, I'm tasked with building a queue from as many stacks as I'd like, trying to get the fastest implementation possible. The best I can think of is using two stacks and as you enqueue items you push them on the first stack stack, but every time you want to dequeue if there are n items...

Homework Statement Assume an elastic collision (ignoring friction and rotational motion). A queue ball initially moving at 2.2 m/s strikes a stationary eight ball of the same size and mass. After the collision, the queue ball's final speed is 0.61 m/s. Find the queue ball's angle \theta...

Hello everyone, I have been trying to figure this problem since hrs, please help me out. It is most likey very easy for you people. I think the problem is mostly syntax but here it is. I am writing this program which uses Stack and Queue ADT . If you look at the code the program is...

I hope this is the right 'subforum' to post my question, if not, sorry, I was not sure... What kind of model is airport simulation of a queue (planes land and take off) with one runway (one server only). I am sure about the first and the last parameter but not about the 'middle': M/(const)/1...
