Abstract- This paper presents an X-band voltagecontrolled
hairpin resonator oscillator using GaAs
MESFET varactor. To get wide tuning range, the
hairpin resonator is combined with the MESFET
varactor. It is incorporated into the series feedback
oscillator. The measurement of the oscillator
showed the frequency tuning range of 11.15 MHz
with the output power flatness less than 0.10 dB at

system analysis, we decide current KPI using 4 perspectives from BSC
There are 2 potential issues on current system. First one is that too much immeasurable KPI may lead to subjective evaluation. Another difficulty is that Non-Separation between new growth business & existing business is able to result in de-motivation of new growth business
In order to correct errors and improve efficiency
features1.
fuel cell is a kind of generator that provides electricity, batteries are like warehouses that store electricity.
features2.
The maximum output energy from the battery
= 50% forms of energy+50% heat
=>The energy efficiency is 50%.
features3.
large energy density.
(store a lot of energy per weight)
Recently, as the amount of storage for capacito
Ⅰ. Introduction
1) Location
Russia is located in the north Eurasia continent (Far East Asia ~ Europe). Russia is the largest country in the world which is about 1/8 of the world’s land area. Because of this huge territory, there is an 11-hour time difference between East and West.
2) Climate
The huge territory of Russia also makes a various climate zone. Basically, Russia has continental
Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines that use moving air.
A TSG is a machine that extracts energy from moving masses of water, or tides.
Energy can be captured from tidal streams using two methods,
Tidal fences and Tidal turbines.
Dynamic tidal power or DTP is a new an

1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
