This paper aims to address the problem of modelling video behaviour captured in surveillance videos for the applications of online normal behaviour recognition and anomaly detection. A novel framework is developed for automatic behaviour profiling and online anomaly sampling/detection without any manual labelling of the training dataset. The framework consists of the following key components: (...

Background: Proteins of various compositions are required by organisms inhabiting different environments. The energetic demands for protein formation are a function of the compositions of proteins as well as geochemical variables including temperature, pressure, oxygen fugacity and pH. The purpose of this study was to explore the dependence of metastable equilibrium states of protein systems on...

The geochemical discriminate diagrams help to distinguish the volcanics recovered from different tectonic settings but these diagrams tend to group the ocean floor basalts (OFB) under one class i.e., as mid-oceanic ridge basalts (MORB). Hence, a method is specifically needed to identify the OFB as normal (N-MORB), enriched (E-MORB) and ocean island basalts (OIB). We have applied Artificial Neur...

Geochemical gene is a new promising concept proposed recently in the discrimination and traceability of geological materials also useful tool to recognize geochemical anomalies mineral exploration. Based on lithogenes LG01 LG03, can be classified into nine types LG_CR compositionally. With respect with 11 LG_CR, order eliminate lithological influence further narrow prospecting target area, tung...

Geochemical characteristics of greywacke and intercalated phyllites from Haveri and Dharwad block (long N 75° 10' to 75° 25' E and lat 15° 30' to 45° 00'S and (long 75° 05'E and lat S 15° 15' to 15° 35') of Shimoga basin have been studied to unravel the provenance and the tectonic setting of the greywackes. The greywackes are medium grained feldspatholithic and show presence of perthitic feldsp...

The Ingur alkaline granite massif and the associated Zr-Nb occurrence make up part of largest Mongolian-Trans-Baikal granitoid provinces. is composed arfvedsonite, biotite, alaskite granites. High content HREE determines low La/Yb n (2–7) value a negative europium anomaly (Eu/Eu*≈0.17). They are depleted in Ba, Sr enriched Nb, Ta, Zr, Hf Y. According to their geochemical properties rocks belong...

We quantify the changes in intensity of Brewer-Dobson Circulation (BDC) during sudden stratospheric warming (SSW) and its impact on tropical thermal structure ozone distribution by composite analysis using observations a chemical-transport model. An increase planetary wave activity enhancement BDC before central date SSW is noticed. A positive anomaly observed upper stratosphere. The lower stra...

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past environmental conditions as new tools continue to be discovered and developed. To date, organic geochemical proxies have been developed mainly for use in marine systems and are widely used in paleoceanography. In contrast, organic proxies have been less commonly used on lacustrine sedimentary records. One ...
