Abstract: This article describes the Antenna Interface Standards Group (AISG) standard in telecommunications and details itshardware implementation. It explains how a fully integrated transceiver such as the MAX9947 can help reduce space and cost, andsolve bus arbitrations in base-station tower equipment.
為了能夠滿足基站易于選址、優(yōu)質(zhì)快速的建站要求和易維護(hù)、低成本、高可靠的運(yùn)行要求，本文對(duì)以方艙來實(shí)現(xiàn)一體化結(jié)構(gòu)基站做出一番探討。從系統(tǒng)設(shè)計(jì)的觀點(diǎn)闡述了移動(dòng)通信高性能基站天線設(shè)計(jì)的幾個(gè)關(guān)鍵問題，介紹了智能天線技術(shù)在基站中的應(yīng)用，并且用HFSS軟件仿真了一種新型的對(duì)稱陣子天線，該天線駐波比小于2的帶寬可以達(dá)到60%，具有良好的寬頻帶特性。
Abstract:
In order to meet the station construction requirement of easy site selection and fast base station， and meet the operational requirement of easy maintenance， low cost and high reliability， this paper discussed the unified architecture base station using shelter. Several key problems of high performance mobile communication base station antenna were illustrated from the view of system design， the application of smart antenna in base station was also introduced. And a novel dipole antenna was simulated by using HFSS， the VSWR of the antenna is less than 2， and the bandwidth was reach to 60%. So it has good broadband properties.
Sanos Operating System Kernel ----------------------------- Sanos is an OS kernel for use in PC based server appliances. The kernel was developed as part of an experiment on investigating the feasibility of running java server applications without a traditional operating system only using a simple kernel.

A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value.
Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not.
Input
Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone.
Output
For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise.
Sample Input
10 111
2 110
10 123
6 1000
8 2314
0
Sample Output
yes
yes
no
yes
no
