...Telephone Analysis Report The telephone analysis was conducted with several telephone providers. These providers were AT&T, Earthlink, and Comcast. I received several quotes and information regarding 3 years contract terms. The findings are as follows: Current Service with AT&T: The audit of the AT&T bill revealed a monthly increase for several reasons. One reason the monthly increase arose over several months is that the promotional contract expired after a 24 month term. The price that was originally quoted was based on a 24 month term with the company entering into a new contract after the term was fulfilled, because we failed to renegotiate with AT&T, our bill increased by an average of $150 dollars at its highest price. I have enclosed an AT&T Monthly Analysis to show the increase over the past year. We also had a double increase in our long distance charges during the months of September, October, and November. The charges also made our monthly charges higher. The only consistent charges that we are paying are the internet charge. It was consistent at $54.95 per month. The areas of comparison were on set-up fees, local, long distance, internet, voicemail and installations. The findings are as follows: * AT&T- This term is for 2 years, the local service includes all of our current services plus the internet will be charged at a rate of $139.00 monthly. This includes 3 lines, long distance, internet, and voicemail. There are no setup fees...

...1. INTRODUCTION Title of the article is “Minimizing the sum of earliness/tardiness in multi-machine scheduling: a mixed integer programming approach”, and which at first defines the ET systems briefly. An early or late delivery will affect cost directly and objective of the ET problem fits perfectly. Assumptions in this problem are; • Due date assignments; being JIT is important to have maximum benefit from the sold product. • Penalty costs for being early or late; both situations cause penalty costs from warehouse or customer. • Sequence dependencies; machines setups are important in some cases and also the precedence may be required. • Machines; single or multiple machine systems are designed and N jobs are assigned to M machines. Moreover expectation is to reduce penalty costs by assigning in the right sequence. The author constructed a model by considering the above definitions and made a first draft, provided in the appendix 1. The objective function is about reducing the sum of earliness and tardiness costs with respect to the times of being early or tardy. First constraint claims the equality of the due date in terms of the time including the completion, earliness, tardiness, which restricts the values of being tardy or early because the due dates are appointed. Second constraint is a determination factor in binary system where if Z11 equals to 1 that job is held on machine 1 otherwise 0. Third and fourth constraints define the relation between precedence of jobs...

...Hello again, its been six months since my last letter and through that time a lot of new things happened to me. I have finished my second year, successfully if I may add, and went out to semester vacation, which unfortunately ended two weeks ago. During the summer I spent time working at the coffee place near my house, and spent a lot of time with my family do to the fact that my older sister gave birth to my beautiful niece. They've named her Evellin, and she's almost one month old. I've tried to help my sister as much as I could towards the birth by taking care of my 3years old nephew. After Evellin's birth, I'm spending most of my time with them. The third year is filled with new and interesting courses, which involve less math and more theoretic knowledge. Finally we're beginning to learn more about of major, and from it looks I'm about to have a pretty interesting career. It was very fun to see everyone from my class again, I really love the people who study with me. we've created a very cohesive group. At Rosh Hshana we began our volunteer project from "LATET" at the super market, collecting food for the needy families. The project went very well, and continued for a week and a half. We were able to break our own record with the number of mills we collected. I would like to wish you a great year; followed with joy and happiness. Thank you so much for giving me the opportunity to...

V-Time: this is voluntary overtime to meet production needs; extra hours are 'banked' and taken as time off or as extra pay. It differs from flexitime where starting and finishing times are staggered, and can mean reduced or increased weekly working hours over a period of time. Work-life balance, workplace culture and maternity/childcare issues - A literature review Zero hours contract: this is a flexible contract that does not specify the amount of time a worker will spend per year on their employment, leaving it open to meet demand. E-working: the term used to describe flexible working that can be done from any location using technologies such as laptops, wireless internet connection and mobile phones. Teleworking: this is where the location is flexible by using technologies to complete work - this allows work to be done from home; also known as e-working.

...1. John wants to have an interest income of $3,000 a year. How much must he invest for one year at 8%? i = prt 3000 = p × 0.08 × 1 3000 = 0.08p p = 37,500 2. Jane owes the bank some money at 4% per year. After half a year, she paid $45 as interest. How much money does she owe the bank? i = prt 45=p*0.04* 1/2 45 = 0.02p p = 2250 3. Robert deposits $ 3000 in State Bank of India for 3 year which earn him an interest of 8%.What is the amount he gets after 1 year, 2 years and 3 years? Solution: In every $ 100, Robert gets $ 8. (Since rate is 8% → 8 for every 100) Therefore, for $ 1 he gets = $ 8/100 And for $ 2000 he gets = 3000 x 8/100 = $ 240 Simple Interest for 1 year = $ 240. Simple Interest for 2 year = $ 240 x 2 = $ 480 Simple Interest for 3 year = $ 240 x 3 = $ 720 Therefore, Amount after 1 year = Principal (P) + Simple Interest (SI) = 3000 + 240 = $ 3240 Amount after 2 years = Principal (P) + Simple Interest (SI) = 3000 + 480 = $ 3480 Amount after 3 years = Principal (P) + Simple Interest (SI) = 3000 + 720 = $ 3720 We observe from the above example that, the Interest cannot be calculated without Principal, Rate and Time. Therefore, we can conclude that Simple Interest (S.I.) depends upon: Principal (P) (ii) Rate (R) (iii) Time (T) And therefore, the formula for calculating the simple interest is Simple Interest (SI) = {Principal (P) × Rate (R) × Time (T)}/100 Amount (A) = Principal...

...majority of people now-a-days having Netflix, so you will get a lot of feedback and different opinions. My opinions on your questions are followed: I do not think the increase in price is going to hurt Netflix. Like you mentioned, cable along with satellite are quite expensive. I became a Netflix customer earlier this year, and since then I have used Netflix more than our satellite TV. The $1 increase does not bother me, especially since it will not affect me until next year. Nor do I think new customers will be bothered with it. As long as they use that extra revenue to their advantage to be ahead of their competitors and provide more for their customers then their customers will not mind paying for it. It’s obvious that one best way Netflix can increase their revenue other than raising their prices is to add advertisement, however, I believe this would cause a down fall in customers. So possibly taking another route would be best for them. Maybe they can lock their customers in by providing contracts, or let their customers pay yearly rather than monthly. With contracts they can provide short ones of six months or one year, and longer ones for maybe three to five years. For myself, I rather just pay one big amount yearly than having to deal with paying it monthly. The can also provide a discount for paying it yearly. I do not think the market has saturated for Netflix. Netflix...
