High frequency variable oscillator is central to the construction of high speed clock for data communication. A very wide variable frequency oscillation is designed that could be used in data communication for reliable and fast data transmission. A voltage controlled oscillator in Colpitt configuration is used in the design. The design is found to be capable of producing frequencies from 800MHz to 1.5GHz for a reverse biased voltage (VR) of 0 to 25V while maintaining a good tuning flatness throughout the range. The design is found to be free from noise and frequency variations over the tuning range.
Ocenjujuci rezultate I sv. rata, kao oslobodjenje ipobedu demokratije nad autoritarizmom ("mracnim vekovima"), znaci ponistenje nauke u istorijji i prelazak u politikantstvo. Svakako, kraj rata je doneo slobodu okupiranim zemljama i narodima ali i razaranje drzavnosti, pre svih, Rusije i Nemacke (koja, do danas nije povratila svoj suverenitet). Posebno, jos tokom rata, pod Kerenskim ("slucajno",sluzbenikom MI6), pre dolaska Lenjina, Trockog, ... i komunista na vlast, toko prvih meseci 1917, u potpunosti je razgradjena drzavnost (njene institucie) Rusije, kao i nemacke i austrijske carevine(i dodatno, turske).
The real estate market is expanding in a fast speed as well as the demand for the real estate projects, so many property portals have been established to help the real estate agents and buyers with their property related needs.
The reality that Southampton blends the different natural and organic bonuses among the shore while keeping a distinctly New York attitude, indisputably makes it one of the few country's most top notch online sites for buying the other property or home. Very close up your eyes and take note to be the mayhem of the metro area carefully fades and locate all by yourself swaying with regard to the tempo of soft surf that act like the range of motion from this relaxing metropolis. Its proximity in the Atlantic Ocean definitely makes the metropolitan area a haven for sunbathers, fishermen and swimmers as well. No matter if you're indulging in a game of golf for an top level school by day or enjoying a delightful candlelit meal on your glamorous sail boat experience by occasion, you are likely to obviously feel the unrivaled bliss of buying another property with this exquisite place.
Rail inspection is an important task in railway maintenance. The speed and loads of trains have been increasing greatly in recent years, and these factors inevitably raise the risk of producing rail defects. Mainly the discrete surface defects impact the riding quality and safety of a railway system. However, it is a challenge to inspect such defects in a vision system because of illumination inequality and the variation of reflection property of rail surfaces. This project presents a realtime VIS for discrete surface defects of rail heads. VIS comprises the Image Acquisition Subsystem (IAS) and the image analysis subsystem. IAS acquires gray rail images for the surface of a rail head, and the latter processes rail images and detects possible defects. This paper propose the Local Normalization(LN) method to enhance the distinction between defects and background in a rail image, considering illumination inequality and the variation of reflection property of rail surfaces
With the advancements in optical and satellite communications for high speed long range data transmissions, serrated antennas plays a vital role. In this work we have designed a Edge Serrated Microstrip Patch antenna used for these applications has been modeled on FR4 substrate as a dielectric medium which has a relative permittivity value of 4.4. The proposed antenna was resonating at two different frequencies in L & S band Microwave frequency ranges. This antenna was fed with coaxial feeding and was designed in a software HFSS.
This paper presents an enhanced 32-bit carry lookahead(CLA) adder implementing using the constant delay (CD) logic, targeting at full-custom high-speed applications. The CD characteristic of this logic style regardless of the logic type makes it suitable in implementing complicated logic expressions such as addition. CD logic exhibits a unique characteristic where the output is pre-evaluated before the inputs from the preceding stage is ready. This feature offers performance advantage over static and dynamic domino logic styles in a single-cycle multistage circuit block. Several design considerations including timing window width adjustment and clock distribution are discussed. Using 65-nm general-purpose CMOS technology, the proposed logic demonstrates an average speed up of 94% and 56% over static and dynamic domino logic, respectively, in five different logic gates. Simulation results of 8-bit ripple carry adders show that CD logic is 39% and 23% faster than
As the world runs fast, its our duty to run with the world compensating its speed. There is an urge to prove everyone unique. Hence time management play a worthless role in the daily work of a person. At morning it is a herculean task to wake up from the bed. “Let me sleep for some more time” is the first slogan of everyone every morning. But feeling guilty for not waking up in the morning is also encountered in several cases. In this paper we propose a novel “Murderer Algorithm” based automatic waking up system that helps to wake up every morning. The uniqueness of the system is to make the person in the bed to wakeup and get away from the bed. The device employs simple capacitive touch sensor to sense the presence of a person and also a brig

Many times you face with car paint problems, such as car’s paint getting chipped off due to one reason or other. This can happen by chance when your car scratched past against a wall or a bush, or a lorry truck tossed few marble size stone chips on your car’s hood while changing lanes, ripping off the car’s paint on several places.
