...Optimal Power Allocation and Scheduling for Two-Cell Capacity Maximization ∗ Dept. Anders Gjendemsjø∗, David Gesbert†, Geir E. Øien∗ , and Saad G.

In [10] it is assumed that each base station, when it transmits, transmits with maximum power Pmax . Which base stations that should be active at each time slot is decided according to a rate maximization objective. However, no proof of optimality is given for the on/off power allocation. In [11] transmit power allocation for a downlink two-user interference channel is studied under a sum transmit power constraint and the assumption of symmetric interference. The derived power allocation depends on the level of interference; when the inference is above a certain threshold the total power is allocated to the best user. For interference less than the threshold, the available power is divided among the two users according to a water-filling principle. However, due to the sum power constraint and symmetry of interference assumption these results are not readily applicable for two-cell power allocation, where it is more reasonable to assume individual power constraints...

...Team 3 National Cranberry Cooperative Analysis and recommendations 1. 2. The resource with least capacity determines the maximum long-term achievable throughput rate. Because wet and dry berries follow different routes at RP#1 there will be a maximum achievable throughput for each. The capacity of the dryers is the bottleneck for the wet berries. The maximum throughput for wet berries is 600 bbls/hr. For dry berries the separation process is the bottleneck. The maximum throughput for dry berries is 1200 bbls/hr. The percentage of wet berries to dry berries would affect the throughput rate. Given the current proportion of berries received the capacity of the dryers would be the maximum throughput of the system. The dryers are the system bottleneck. And as the trend of water harvesting continues, this situation worsens. All the process/resources at RP#1 contribute to the throughput but the limitation is the bottleneck. 3. The trucks wait because the processing capacity is less than the system input. And the temporary holding bins are inadequate to buffer the berries coming in and the plants processing capacity. But by using the Theory of Constraints to identify the system bottle necks we are able to discover the root cause of the waits. The large back log of berries is caused by several factors The plant is not currently equipped to handle the supply of wet berries. This problem has likely been increasing over the years as more cranberries are being...

I do not know if our government system has been to discourage managers to adhere to the objectives of the company, which is growing fast and being above average ROA compared with other companies in the industry. I want you to have it in mind when you are evaluating our system. proliferation Metal industry Metal Service Centers purchase from many factories (e.mills), including USX, Bethlehem, Alcoa, Reynolds and smaller companies like Crucible, Northwestern and Youngstown . These suppliers sell products in large batches. By doing this they maximize the throughput capacity of large production end collisions (e.run). Service Centers sells its consumers in smaller batches and shorter processing time. The distribution of metal industry was generally considered of mature, highly competitive and sundering industry. Still has a lot of firsts in the industry who have given Service Centers opportunity to grow. cuts in steel plant in their effort to be more competitive by increasing production capacity, most large national metal manufacturers have been withdrawn product lines by skip specialty produced in limited quantities. Also, they had to reduce service to customers by reducing the salesforce size and technical services. Full-line service centers, have noticed that many of their customers prefer to do...

...Anthony Nedelka Journal #2 9 September 2015 Technical goals for a company can include: * Scalability * How much growth is this network going to have to support? When planning for this, you want to make sure that the company is going to have room to grow, which may vary depending on the company. For example, Target is probably going to be a faster growing network than a local mom/pop shop. * Availability * How long your network is available to users. Basically: is your network and up and running all day, every day? * Network Performance * This includes categories that measure the throughput of data and how efficient your network actually is. (Optimum Utilization) * Security * Security design is one of the most important aspects of a network. Without proper security your network is vulnerable to online cyber attacks that can cripple and steal from your databases. * Manageability * This technical goal is going to vary based on company needs. Some customers are going to have more precise goals. The book talks about a company planning to record the number of bytes sent and received to each router. Other clients may have less specific goals than this, it just tends to vary based on company objectives. * Usability * Close to manageability, but different. Usability refers to people who are accessing and using the network you have setup. Your network needs to be easy to use for them (different from management. Easier...

...operations. We performed some analysis in Excel and created a dashboard to illustrate various data. Specifically, we regressed the prior 50 days of jobs accepted to forecast demand over the next 2 - 3 months within a 95% confidence interval. The yellow and grey lines represent the maximum and minimum variability, respectively, based on two standard deviations (95%). Exhibit 1: Forecasted and actual demand by Day 50 and Day 270 Our two primary goals at the beginning of the simulation were as follows: 1) Eliminate bottlenecks and increase capacity in order to meet forecasted demand 2) Decrease lead time to 0.25 days in order to satisfy Contract 2 and maximize revenue In order to achieve these goals, we would need to know the capacity and throughput time of the entire system. We used the time required by each machine to process a lot to calculate capacity per station and then capacity of the entire production line (380 kits/day or 6 orders/day). In Exhibit 2 we can observe that the capacity of the production line is given by the station that produces the least number of units per day. Exhibit 2: Capacity of the production line The Decisions We decided to work with the maximum variability of demand because there was a penalty for late jobs and because there was no revenue for orders that took more than “x” days. Since the simulator runs at a rate of 34 simulated days per each real day, we had to estimate the demand for the following 34 days. Day 1 We identified the bottleneck...

...Home Network Speed Name Wilmington University INTRODUCTION- The Speed test was carried out for my home network through the period from 8/31/15 to 10/13/2015. Various screen shots were taken, and with the help of them, the graph was plotted. The different type of the network pattern was seen. The different changes were found while performing these tests. The jitter shown variations from 17 to 175 ms. One of the reason for this cause is network congestion. It can be at the router interfaces or in a provider or carrier network if the circuit has not been provisioned correctly. There is a variation in ping from 11 to 14 ms. As the there is inadequate bandwidth a ping becomes variable. In addition, the speed claimed by Comcast is 100mbs but it showing minimum speed of 4.60 mbps and maximum of 13.25 mbps. ANALYSIS: With the graph's assistance, I can watch the general pattern of net index and unpredictable values of ping and jitter for my home system. My ISP is Comcast. As indicated by this chart, I can say that Comcast is not ready to satisfy the speed that was guaranteed for my agreement. Variations of Ping and Jitter prompts lessened reaction both for upload and download speeds. I have utilized different devices, for example, Smartphone, three tablets to the same modem/switch that made the heap on my home system. Particularly amid evening time and late evenings, I have seen a drop in the speed. I think my plan ought to be checked that will help me to get great speed for what...

Please read the Assignment Collaboration Guidelines in Course Syllabus: Collaboration between groups is not allowed; however, if you hear something from some other group, please give a reference. Below, write your answers to Questions 1-4 (on BB/Cases). Your analysis should be based on the assumptions listed in the Syllabus. If you need to make additional assumptions to answer a question, clearly state them, logically defend them, and then proceed to answer the question accordingly. The idea is to answer the questions concisely. Double spacing is preferred, 1.5-line spacing is the minimum (consider the reader’s eye strain). 1. Analyze the current process. Using the process flow map (available on CTools) of the current process at Receiving Plant No.1, mark the capacity and utilization of each of the resources. Show the flows of wet and dry berries separately. First we receive 18,000 barrels over a 12 hour period which leads to a 1,500 bbl/ Hr, Then 75% of 1,500 total berries per hour equal 1,125 bbl/Hr and the remaining 25% or 375 bbl/Hr are dry berries. While our Dumper is holding a capacity of 3,000 bbl/Hr and utilizing only the 1,500 bbl/Hr we are receiving. Those berries would then split up in the dry and wet storage bins. Dry bins have a capacity of 4,000 bbl/Hr which is 16 bins holding 250 bbl/Hr each. Whereas the wet bins kept a storage capacity of 3,200 with 8 bins holding 250 bbl/Hr...

...Blast from the Past and The Truman Show both depict the story about men growing up in an artificial world. Since they are born, they live in a world that is created by others and they do not contact with the real world. However, both of the men in these two movies do not give up their dreams and they are determined. They are eager to get out of the present situation and they have a strong desire to live in the way they like. Finally, through their efforts, they shake off the shackles and both of them lead a free and happy life. Also, there is an interesting thing appears in both movies that the Christian image is mentioned. In Blast from the Past, each time Adam’s family ascent to the ground, the druggies who are religious acolytes are pious and reverent to them, thinking Adam’s family are Father and Son. In The Truman Show, after the vicious storm, Truman emerges from the water in a cruciform position which represents the Jesus after being tortured. Although the style of the two movies is similar, there are a lot of differences between them. First of all, Adam lives in a world full of love and what around him is the beautiful and positive aspect of life. Since he is born, his parents, who are the only person that he can contact with, tell him what the real world is. Moreover, his parents teach him dance, languages and sports. He learns from his parents to be modest, kind and a man of morality. Although his parents create an unreal world for Adam, they are not on...

...Abnormal Psychology 2300 The Diagnosis of Edward Gein Rainy River Community College Delaney Peters 13 November 2013 Edward Theodore Gein was born to Augusta and George Gein on August 27th, 1906 in La Crosse, Wisconsin. Edward had an older brother named Henry. George Gein was a violent alcoholic who was frequently unemployed. Augusta on the other hand followed to a different beat she was a very religious individual whom had very harsh opinions on other women. Often times, Augusta would refer to other woman as prostitutes and instruments of the devil. According to Dr. George Arndt, a psychiatrist that studied the case of Edward Gein, Augusta’s obsessive and negative perspective on women rubbed off on her children, more specifically on Edward. She reserved time every afternoon to read her children verses from the bible, usually selecting graphic verses from the Old Testament dealing with death, murder and divine retribution. Without surprise, Edward himself became a target for bullies. Classmates and teachers recalled off-putting mannerisms, such as seemingly random laughter, as if he were laughing at his own personal jokes. Despite his poor social development, he did surprisingly well in school and was often viewed as an average academic student. Many sources cite that Edward’s mother Augusta often beat her children because she was convinced that they were going to become just like their father, a drunken failure...
