the interaction between sea and atmosphere has profound effects on the regions climate. meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surfa...

As semiconductor manufacturing entered into nanoscale era, performance degradation due to Negative Bias Temperature Instability (NBTI) became one of the major threats to circuits reliability. In this paper, we present a model and analysis of NBTI impact on circuit delays. First, we model NBTI impact on gate intrinsic delay and output transition delay. The insights of our models reveal that NBTI...

A consideration of the temperature characteristics or thermal increments for locomotion in Planaria shows that they agree essentially with those reported for certain activities of other animals (Crozier, and Glaser). A process with the lowest increment (micro = 7,000 to 8,000) assumes control of the locomotor rate at temperatures above 20-22 degrees ; that with the highest increment (micro = 18...

The objective of this paper was to organize the information, classify and resolute the altered frequency of climatic types of different micrometeorological stations in Kathamndu valley ( Kakani, Budhanilakantha, Godavari, Khumaltar, Airport, Panipokhari, Nagarkot, Khokana and Thankot). Analyzed data of the stations revealed the prevalence of ‘’C’’ (humid mesothermal)as the major type of climate...

1. introduction one of the six great challenges recognized by the world climate researches program (wcrp) is the prediction and the characteristics of extreme events. the outcomes of various sources indicate that the extreme climate events have significantly increased over the last decades. trend analysis of extreme temperature indicators is of crucial importance in estimating the trend of glob...

In this paper, AISI 441 stainless steel was investigated as a casting using the investment process (ICP). The microstructure and mechanical properties of as-cast normalizing treatment samples were analyzed. results show that tensile strength prepared by ICP is 458 MPa, elongation 22.7%. Normalizing can improve performance ICP, but have slightly decreasing trend with increasing temperature time....

Computational fluid dynamics (CFD) has become a widely used tool for predicting hazardous scenarios. The present study aimed to assess CFD prediction applied LPG containers under heating. Thus, two cylinders, each filled with propane or butane, were experimentally exposed fire, and the pressure increment was recorded. results compared those provided by method (Ansys Fluent). limitations of are ...

analysis of the spatial and temporal trends of precipitation and temperature are pertinent for future development and sustainable management of water resources in a given region. in this paper, we present a study concerning the climatic behavior of two principal observables variables, viz. monthly temperature (maximum and minimum) and mean precipitations obtained from the measurements carried o...
