Abstract: This paper is an overview of fuzzy set hypothesis connected in group examination. These fluffy grouping calculations have been broadly contemplated and connected in an assortment of substantive territories. They likewise turn into the real systems in group investigation. In this paper, we give a study of fuzzy grouping in three classifications. The main classification is the fuzzy grouping in view of fluffy connection. The second one is the fuzzy bunching in view of target work. At last, we give a diagram of a nonparametric classifier. That is the fuzzy summed up k-nearest neighbor run the show. Picture division particularly fuzzy based picture division systems are generally utilized due to powerful division execution. Therefore, an immense number of calculations are proposed in the writing. This paper shows a review report of various kinds of traditional fuzzy grouping methods which accessible in the writing.

Paper Title:

Abstract: Telecommunications services square measure the foremost necessary parts within the new information society. Information and Communication Technologies (ICTs) represent a major challenge in terms of productivity, growth and jobs. Ethiopia is a land of cultural diversity. It is the part of tropical region of Sahara and Sub-Sahara continent. Eighty percent of the population in Ethiopia is living in remote and rural areas, where there is a very little basic facilities are available for daily needs. Ethiopia is the part of African Union and situated at east Africa and referred as horn of Africa. The AU and its Member country should quickly adopt rapidly-developing ICT so as to bridge the e-skills gap and be in a very position to form a true knowledge-based economy. The beginning of the telecommunications market to competition had the impact of a catalyst in a various sector formerly reserved oligopolies. To enhance these developments, the Africa union decision-making authorities have adopted legislation to synchronize with technological and current market requirements.

Abstract: The laser fields are very wide and advance for the coming optical generations. Fiber lasers are worth to play a vital role in the upcoming new uprising of science due to their role in experimental operations and to their strong experimental arrangement for any starter. Different categories of optical laser found for widespread use such as Erbium Doped Fibre laser (EDFL), Ytterbium Doped Fibre Laser (YDFL). We consider about EDFL and YDFL which are made by doping the fibre core with rare-earth elements of Erbium and Ytterbium respectively. The system has been designed to analyze the gain and pump power and output power dependence of the optical laser EDFL and YDFL for various fiber lengths. The output power of YDFL in ring resonator is 40mW and in linear resonator is 25mW, which is better than EDFL which gives 20mW in ring and 10mW in linear. The YDFL gives better output power then EDFL. Ring resonator is better than linear resonator.

Paper Title:

Abstract: In any fibre optic communication systems the transmission distance is limited by the fibre losses. The recent approach to overcome the loss limitation is the use of optical amplifiers which ensures the accomplishment of fibre optic communication systems for long distances efficiently. Different categories of optical amplifiers found for widespread use such as Erbium Doped Fibre Amplifier (EDFA)], Ytterbium Doped Fibre Amplifier (YDFA). We consider about EDFA and YDFA which are made by doping the fibre core with rare-earth elements of Erbium and Ytterbium respectively. The gain of EDFA is 10dB, 15dB, 20dB and 25dB with fiber length at 5m, 7.5m, 10m and 12.5 m respectively and the gain of YDFA is 15dB, 20dB, 30dB and 30dB with fiber length at 0.5m, 0.75m, 1.0m and 1.25 m respectively. Amplifier performance improves with increase with fiber length.

Paper Title:

Abstract: Optical intensifiers are ordered in light of the system that is fused for enhancement of the flag. Optical amplifiers are helpful in long separation correspondence that requires least weakening misfortune. This datasheet will expand on the development, working guideline and the uses of the different kinds of optical amplifiers. Doped fiber amplifiers (DFAs) are optical amplifiers that use a doped optical fiber as a gain medium to amplify an optical signal. They are related to fiber lasers. The signal to be amplified and a pump laser are multiplexed into the doped fiber, and the signal is amplified through interaction with the doping ions.

Abstract: In this paper a three phase 6-pulse convertor model is designed. The Synchronized 6-Pulse Generator block can be used to fire the six diode of a six-pulse converter. The output of the block is a vector of six pulses individually synchronized on the six diode voltages. DIODE, MOSFET and THYRISTOR are used as a controlled rectifier which reduces the total harmonics distortion in output current and voltage.
