...Risk Analysis on Investment Decision Silicon Arts, Incorporated (SAI) is a manufacturer of circuits that are used in the manufacture of electronic equipment items. During their initial years in operation, there was an increase in the industry followed by a 40% decline. In order to remain competitive and stay profitable, SAI controlled expenses. Current trends indicate the industry may be on the rise again. SAI wants to develop some new capital investment projects that are in line with their goals: increase their market share, and keep pace with new technology (University of Phoenix, 2007). Future Scenarios The first task in the simulation was to examine probable future scenarios that could potentially affect SAI cash flow with two projects, Dig-image and W-Comm. Part of SAI’s plans is their desire to earn $54 million in their first year by selling 400,000 units, however they first need to determine their working capital. “Working capital rises over the early years of the project as expansion occurs. However, all working capital is assumed to be recovered at the end, a common assumption in capital budgeting” (Ross, Westerfield, & Jaffey, 2005, p. 183). SAI is expecting growth will be 20% in the first three years and then decrease 10% annually in years 4 and 5. SAI is expecting increasing competition, decreasing prices, and a short lifespan of the technology that could be obsolete before the lifespan of the project itself. Although increasing the volume of units will increase...

...sizes does stop and wait give an efficiency of at least 50%? Consider the use of 1000-bit frames on a 1-Mbps satellite channel with a 270-ms delay. What is the maximum link utilisation for: (i) Stop-and-wait flow control? (ii) Sliding-window flow control with W = 127? (iii) Sliding-window flow control with W = 255? (iv) Sliding-window flow control with W = 511? With a k-bit sequence number field the maximum window should be 2k. Why is the maximum allowable window 2k -1? Two stations communicate via a 1-Mbps satellite link with a propagation delay of 270 ms. The satellite serves merely to retransmit data received from one station to another, with negligible switching delay. Using HDLC frames of 1024 bits with 3bit sequence numbers, what is the maximum possible data throughput (not counting the 48 overhead bits per frame)? Solution (a) Consider a window W = 2k and a sender that has successfully transmitted all frames in that window (SEQ = 0 … 2k - 1). The receiver will return an RR 0, but does this mean all 2k frames have been received (next SEQ is 0) or that all frames have been lost (next SEQ is also 0)? (b) Tprop = 270 x 10-3, Tframe = (L=1024)/(R=106) = 1.024 x 10-3 so a = 263.7 and 1 + 2a = 528.3. With k = 3 then W = 7 and since W < 1 + 2a, the utilisation is: W 7 U= = = 13.25 × 10 −3 which means an effective throughput of U x R = 13.25 kbps. 1 + 2a 528.3 But only (1024-48)/1024 = 0.9531 of the transmissions pertain to actual data, so the data throughput is 12.63 kbps...

...The Caldera Cont. [W-07.2] == Once back at the Caldera, open the SPECIAL CHEST that contains a GORGON EYE and use your Fire Blades to break the gears holding the archimedean screw together. You may now backtrack to that new type of door you saw earlier, and break it down. Inside grab the GREEN CHEST and a RED CHEST before continuing along the path. When you slide down the next ramp you'll land onto a platform where you have to face two Minotaurs and some firebirds. Grab the BLUE/GREEN CHEST and then pull the lever here. Jump onto the lava rock and you will float along the lava flow. You will fight a small wave of fire crab-spiders before eventually needing to jump onto a wall as the lava rock begins to burn away. At the top open the SPECIAL CHEST that contains a MINOTAUR HORN and be sure to save at the Save Point. Sidle your way across the ledge to your right then break the gears on another one of the archimedean screws. Climb up the ledge here and keep moving. At the end of the path open both the GREEN CHEST and BLUE CHEST before breaking down another fire door. Open the SPECIAL CHEST and sidle your way through the crevice here and around into the Volcano Core. _______________________________________________________________________________ | NOTE: If you find all the SPECIAL CHESTS some will only contain Orbs, but if| | you miss some, the others will compensate. | |_____________________________________________________________________________| Before you can get completely around...

...(Greto, Schotter, & Teagarden, 2010). However, after the war Toyota faced bankruptcy until the US submitted a request for the production of vehicles for the US Military (Greto, Schotter, & Teagarden, 2010). Toyota would establish their first subsidiary in the US and would begin production in 1988 (Greto, Schotter, & Teagarden, 2010). The global automobile industry was estimated to be US $ 1.9 trillion business with Toyota moving to number one in sales in globally in 2008. However, that success would come amongst great adversity and leadership challenges (Greto, Schotter, & Teagarden, 2010). In the beginning, Toyota’s leadership came from within the Toyoda family; however, after an illness the organization found it necessary to go outside the Toyoda family for leadership (Greto, Schotter, & Teagarden, 2010). The company was built on the principle of safety first, quality second, and volume third, known as the Toyota Way (Greto, Schotter, & Teagarden, 2010). The Toyota Way, is known throughout the world of organizational management and many organization have patterned their organization after Toyota (Greto, Schotter, & Teagarden, 2010). The Toyota Way is based upon long term planning, addressing problems and not hiding problems, encouraging teamwork, and most important,...

...electric vehicles are very much environment friendly. Still electric vehicles are falling behind in the automobile industries due to the problem of storage of energy. This paper is based on the concept of charging the batteries of an electric vehicle when it is in motion or propelling. This may be done by using the energy of wind which is caused by the relative motion between the vehicle and the wind surrounding it. Wind turbines can be mounted on the body structure of the vehicle to generate electricity in such a way that it must not create any additional drag force (rather than the existing drag force due to frontal area and skin friction) upon the vehicle. An elaborate aerodynamic analysis of the structure of the vehicle along with the flow pattern and wind turbine is presented in the paper. Some techniques and methods are proposed to minimize the drag imposed by the introduction of the turbines as much as possible. Optimum values of different design parameters and rated velocity of...

The first option is to covert his facility into a high technological facility with the latest manufacturing technology. Guillermo Navallez’s initial cost for the equipment will be high, and he will have to weigh the cost of equipment with the benefits that the equipment will bring to the organization over time. Guillermo Navallez second option is to become a broker for another manufacturing company. Guillermo Navallez will have to change his business from being a manufacturer to a distributor. The third option that Guillermo Navallez has is to simply keep on his current path and hope he doesn’t go out of business.

...capital management. It is important that the decisions being made in regards to financial management be concise, educated, and understandable. This paper addresses the three types of financial management decisions which guide companies in the direction for success, and will point out a few possible ethical problems company’s may face in their quest for that success. Part 1: Capital Budgeting Capital budgeting is the process of planning and managing a firm's long-term investments. “Evaluating the size, timing, and risk of future cash flows is the essence of capital budgeting” (Ross, Westerfield, Jordan, 2007, p. 5). The size, timing, and risk of future cash flows are the most important things to consider with capital budgeting. Formal methods that are used in capital budgeting include profitability index, valuation of future cash flows, and net present value. Profitability index is the present value of an investment’s future cash flows divided by its initial cost, also known as benefit-cost ratio. The index measures the value of each dollar invested in the company and is rationed from the present value of the benefits (PVB) to the present value of the costs (PVC). The index is used instead of Net Present Value, which is the present value of benefits minus present value of costs, when evaluating mutually exclusive proposals that have different costs. The advantages of using the profitability index are it tells whether an investment increases the firm's value; considers...
