The 408 MHz B 3 . 1 Survey
We present a new 408 MHz survey (B3.1) carried out with the " Croce del Nord " radiotelescope in Bologna. The survey coordinates limits are −2 • 00 ′ to +2 • 15 ′ in Dec. and 21h to 24h, 00h to 17h in R.A., equivalent to 0.388 sr. The B3.1 is complete to 0.15 Jy but many sources down to 0.1 Jy are included. Our aim was to select a new and complete sample of Ultra Steep Spectrum (USS) radio sour...

متن کاملA Correlation Interferometer for 408 MHz
One day in the 1980’s I was helping a visiting scientist get his experiment set up at a remote site to the west of Ottawa. This site contained the decaying remains of decades of radio experiments. Among some trees I found an old shed, crammed to the roof with yagi antennas, combiners, hybrids and many matched lengths of heliax coaxial cable. Many were broken, but mixed in with the debris were s...
متن کاملthe effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولSco X-1: Energy Transfer from the Core to the Radio Lobes
The evolution of the radio emission from Sco X-1 is determined from a 56-hour continuous VLBI observation and from shorter observations over a four-year period. The radio source consists of a variable core near the binary, and two variable compact radio lobes which form near the core, move diametrically outward, then fade away. Subsequently, a new lobe-pair form near the core and the behavior r...
