Investments in Emerging Countries Essay Example | Topics and Well Written Essays - 250 words

Investments in Emerging Countries - Essay Example Higher global crude oil price is expected to benefit Russia’s economic recovery. But this benefit will be carried away by the expected capital outflows. The capital outflow of Russia is much higher compared to that of the inflow. Business Risks in Czech Republic: The political risk of Czech Republic is lesser compared to that of Russia. Rising oil price is one of the business risks in Czech Republic. Annual oil production of the country is much below its annual oil consumption. (Theodora, 2011) Therefore, the rising oil bills will increase cost of production and paving way for an inflationary situation in the country. Another risk of the country is the strict legal system. Bureaucracy is at an increased rate in the country. Another risk factor is that the capital market of the country is small. Czech Republic is mostly an export related economy with majority of its exports being to other European countries. Therefore, the performance of the country’s economy depends lar gely on the stability of other European nations. Best Investment: The analysis of business risks at both the countries show that Czech Republic is better placed with less investment risks than Russia. Economic factors are positive to Czech Republic than Russia. Therefore, Czech Republic is the better investment destination than Russia.

UWB Ad-Hoc Networks Essay Example | Topics and Well Written Essays - 10000 words

UWB Ad-Hoc Networks - Essay Example gnal has a bandwidth that exceeds the lesser of 500 MHz or 20% of the center frequency, there is an authorized unlicensed use of the frequency range starting from 3.1 GHz and up to 10.6GHz, also the emission limit is -41.3 dBm/MHz. This technology uses the Impulse Ratio (IR) method for its transmission; the rate is different for radar and imaging purposes to the communication purposes. The rate of impulses for radar and imaging is in the range of 1 to 100 mega pulses per second. The communication rate can be in a range of 1 to 2 giga pulses per second. This diagram shows how much faster Ultra Wide Band technology is over any existing current technologies also it provides a high level of mobility which is important for a mobile devices it is intended for. The advantage of UWB over traditional radio transmissions is that traditional way would be to modulate the frequency and phase of the signal as well as power, of a sinusoidal wave. However UWB transmits impulse at a specific time, there fore it allows pulse position modulation and time modulation. Among the advantages of UWB that helps to prevent multi path propagation. It gives the possibility of the system to establish the time for an impulse to travel from the transmitter to the receiver in the direct path. The other advantage of UWB IR system is the short length of pulses does not allow them to overlap so the multipath fading is not an issue in this case. On the other hand in a system with high pulse rate there can be inter-path interference, it can be eliminated by error correction coding at the receiver. UWB can be combined with multiple antenna technology that doesn’t only allow increase in transmission speed but increases the reliability of the channel, there are a number of solutions that can increase the transmission speed over the regular SISO (single-input single-output); Technologies like multiple-input and multiple-output (MIMO) allows reaching gigabits per second range of transmission speed.
