This article deals with the analysis of energy efficiency optimization in battery-based photovoltaic pumping schemes. The study builds on previous findings derived from comparison between a direct water system (DPVWPS) and equivalent including lithium-ion battery (LIB). initial experimental results (PVWPS+LIB) were obtained motor-pump group operating at its rated condition 50 Hz. In present wor...

This paper proposes a positive temperature coefficient (PTC) self-heating method, in which EVs can be operated independently of external power source at low temperature, with a lithium-ion battery (LIB) pack discharging electricity to provide PTC material with power. Three comparative heating experiments have been carried out respectively. With charge/discharge tests implemented, results demons...

We propose a new theory that quantifies information in probability distributions and derive a new document representation model for text clustering. By extending Shannon entropy to accommodate a non-linear relation between information and uncertainty, the proposed Least Information theory (LIT) provides insight into how terms can be weighted based on their probability distributions in documents...

1. White Carneau pigeons develop genetic atherosclerosis. The aorta shows intimal cushions at birth, cholesterol accumulation at 9 months of age and definite atherosclerotic lesions by 3 years of age. To determine whether these age-related arterial changes can be prevented by dietary restriction started early in life, 3-month-old pigeons were subjected to dietary restriction (40% of ad lib. die...

The safety of lithium-ion battery (LIB) becomes increasingly critical as the specific energy and cell capacity rapidly increase. Based on the modified current collector technique recently developed for nickel–cobalt– manganese active materials, here we investigate high-energy LIBs based on functional current collectors (FCC). Two high-voltage active materials were tested in our experiments: lit...
