Non - LTE Revisited
The development of sophisticated techniques for quantum-mechanical computations has lead to the determination of large amounts of accurate atomic data by e.g. the Opacity and IRON Projects in recent years, stimulated by the demands of astrophysical and fusion research. Here, we report on the incorporation of such data in a new generation of non-LTE model atoms for a number of elements of astrop...
متن کاملامنیت دگرسپاری در شبکههای LTE
سیستم ارتباطی نسل چهارم مخابرات، مبتنیبر فناوری LTE میباشد. LTE تکاملیافته شبکههای دسترسی بستهای با سرعت بالا (HSPA) است و با تحقق نرخ داده بالاتر، سازگاری بیشتر با شبکههای ناهمگن و معماری شبکه یکنواختتر ارائه شده است. LTE از سری استانداردهای نسخه 8، 3GPP است. یکی از اهداف LTE و هر سیستم بیسیمی، فراهم نمودن دگرسپاری یکپارچه و سریع از یک سلول (سلول منبع) به سلول دیگر (سلول مقصد) میباش...
متن کاملLTE and LTE-Advanced factsheet
LTE (Long Term Evolution) designates the successor to the widespread mobile radio standard UMTS (Universal Mobile Telecommunications System). Its introduction is one of the responses to the rapid growth in mobile data traffic. To date, the volume of traffic transmitted over mobile networks worldwidehas doubled every year. In many countries, including Switzerland, this traffic doubling time is j...
متن کاملEmotive or Non-emotive: That is The Question
In this research we focus on discriminating between emotive (emotionally loaded) and non-emotive sentences. We define the problem from a linguistic point of view assuming that emotive sentences stand out both lexically and grammatically. We verify this assumption experimentally by comparing two sets of such sentences in Japanese. The comparison is based on words, longer n-grams as well as more ...
متن کاملSTEMI or non-STEMI: that is the question
Acute coronary syndromes are usually classified on the basis of the presence or absence of ST elevation on the ECG: ST-elevation myocardial infarction or non-ST-elevation myocardial infarction (NSTEMI)patients with acute myocardial infarction (AMI) need immediate therapy, without unnecessary delay and primary percutaneous coronary intervention (PPCI) should preferably be performed within 90 min...
