Drought is one of the most devastating climate extremes in terms its spatial extent and intensity. Rainfed areas are extremely vulnerable to drought, but effective monitoring may lessen impact such events. This study developed a composite drought index (CDI) for assessing seasonal droughts rainfed Potwar Plateau Pakistan, using remotely sensed observed meteorological datasets. We identified fou...

The kinetics of the O + HCNO reaction were investigated by a relative rate technique using infrared diode laser absorption spectroscopy. Laser photolysis (355 nm) of NO2 was used to produce O atoms, followed by O atom reactions with CS2, NO2, and HCNO, and infrared detection of OCS product from the O + CS2 reaction. Analysis of the experiment data yields a rate constant of k1= (9.84 +/- 3.52) x...

This paper describes the intellectual framework and field of study of affective computing. This is a seminar paper written for course Tik-111.590 Digital media research seminar, spring 2001: “Space Odyssey 2001”. The paper is based on a literature study of affective computing.

Den här uppsatsen behandlar ett antal individer begravda mellan 800 e.Kr. och 1150 e.Kr i ett tidigt kristet gravfält kring ruinen av Varnhems gårdskyrka. Av speciellt intresse är den placeringen som gravarna har i förhållande till kyrkomurarna och vad dessa placeringar innebär statusmässigt. Analys av stabila isotoper har därför utförts på de manliga individerna så att deras diet kan faställas...

Frequent droughts induced by climate warming have caused increasing impacts on the vegetation of Loess Plateau (LP). However, effects drought are highly dependent when occurs and how long it lasts during growing season. Unfortunately, most existing indices ignore differences in different growth stages. In this study, we first established a phenology-based condition index, namely weighted index ...

drought is a major problematic phenomenon mostly for semi-arid areas of iran. during drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. therefore, the assessment of drought effects on plant covers is the most important issue. this research was conducted in 2015 using the extracted vegetation indices from moderate resolution ima...

Drought affects a region’s economy intensively and its severity is based on the level of infrastructure present in affected region. Therefore, it important not only to reflect conventional environmental properties drought, but also target region for adequate assessment mitigation. Various drought indices are available interpret distinctive meteorological, agricultural, hydrological characterist...
