Warning systems as social processes for Bangladesh cyclones

Mesoscale Processes in Tropical Cyclones

I have four long-term goals. My first goal is to finalize the large body of work already carried out by the PI on the predictability of tropical cyclone (TC) forecast tracks out to 72 hours ahead. My second goal is to apply similar, as well as new, ideas to the predictability of forecast intensity out to 72 hours ahead. My third goal is to carry out observing system simulation experiments (OSSE...

Leveraging Localized Social Media Insights for Early Warning Systems

Social Media is more and more positioning as the channel to implement early warning systems for prompt reaction to events that might affect a company’s core business. The enabling of geo-location for social media interactions unlocks new possibilities for decision making scenarios aiming at triage situation where the quality of service decays. In this work we provide a system and a set of soft ...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

Assessing Risks from Cyclones for Human Lives and Livelihoods in the Coastal Region of Bangladesh

As a disaster prone country, Bangladesh is regularly hit by natural hazards, including devastating cyclones, such as in 1970, 1991 and 2007. Although the number of cyclones' fatalities reduced from 0.3 million in 1970 to a few thousand or fewer in recent events, loss of lives and impact on livelihoods remains a concern. It depends on the meteorological characteristics of cyclone and the general...
