ecological changes resulting from climate conditions can severely affect human societies especially in the area of economy and safety. climate catastrophes may cause social and economic tension. forecasting such changes accurately can help the government to control the disasters and to achieve possible benefits (such as water supply in flood). weather forecasting is the application of science a...

A system architecture is proposed to support mobile hotspots. The proposed architecture uses multiple repeaters to relay signals from access routers to vehicles and vice versa. Erasure codes are used in the access router to decompose data packets into fixed size fragments. The fragments are then disseminated to the vehicle through the repeaters. The original packet is reconstructed in the vehic...

Machine translation is the task of automatically translating a text from one natural language into another. In this work, we describe and analyze the phrase-based approach to statistical machine translation. In any statistical approach to machine translation, we have to address three problems: the modeling problem, i. e. how to structure the dependencies of source and target language sentences;...

k-Nearest Neighbor (KNN) is one of the most popular algorithms for pattern recognition. Many researchers have found that the KNN classifier may decrease the precision of classification because of the uneven density of t raining samples .In view of the defect, an improved k-nearest neighbor algorithm is presented using shared nearest neighbor similarity which can compute similarity between test ...

Making sense of, and implementing a new education and training system often results in a cutting-up of the system into more manageable pieces. While it is therefore quite understandable that the Sector Education and Training Authorities’ Education and Training Quality Assurance bodies (SETA ETQAs) have focused their initial energies on the core components of qualifications, namely those parts t...

T ( H r l i p p p r a linical cardiac electrophysiology and cardiac pacing have erged into a common cardiac subspecialty discipline. Comlex cardiac arrhythmias are managed by physicians with pecial expertise in cardiac electrophysiology, the use of cardiac mplantable electrical devices (CIEDs), and the application of ther interventional ablative techniques and pharmacologic reatments. Cardiac i...

1 Truth-relativism For our purposes, truth-relativism can be characterised as the doctrine that in a single world the very same token utterance can take different truth-values when considered in different contexts of assessment. The root semantic idea is already present in Lewis’s 1980, where an utterance of a sentence like “It is raining” is conceived as receiving a truth-value only when the v...

Practices for endo and ectoparasite control in beef cattle were evaluated in two independent experiments. First, the effects of rotenone on Rhipicephalus (Boophilus) microplus ticks were evaluated in vitro and in experimentally infected calves. In the second trial, the effects of grazing systems associated with endo and ectoparasite treatments on parasite burden and weight gain of naturally par...

Aspects of our Solar System’s formation are deduced from observations of the chemical nature of matter. Massive cores are indicative of terrestrial-planet-composition-similarity to enstatite chondrite meteorites, whose highly-reduced state of oxidation may be thermodynamically stable in solar matter only at elevated temperatures and pressures. Consistent with the formation of Earth as envisione...
