The article presents the possibility of verifying efficiency a diesel particulate filter (DPF) with use particle counters using two different measurement methods. tests were carried out at vehicle inspection station condensation counter (CPC) and diffusion charger (DC). This results measurements 50 vehicles. Removal from is prohibited but known phenomenon throughout EU. task periodic technical ...

Particulate mass concentration is a crucial parameter for characterising air quality. The diesel particulate filter (DPF) the primary technology used to limit vehicle particle emissions, but it needs periodic cleaning, process called regeneration. This study aims assess impact of active DPF regeneration on performance and emissions Euro 5 6 vehicles. examined both carbon dioxide (CO2) pollutant...

Although diesel engines have an advantage of low fuel consumption in comparison with gasoline engines, several problems must be solved. One of the major concerns is that diesel exhaust gas has more particle matters (PM) including soot, which are suspected to be linked to human carcinogen. As one of the key technologies, a diesel particulate filter (DPF) has been developed to reduce PM in the af...

Acoustic models of an HMM-based classifier include various types of hidden factors such as speaker-specific characteristics and acoustic environments. If there exist a canonicalization process that represses the decrease of differences in acoustic-likelihood among categories resulted from hidden factors, a robust ASR system can be realized. We have previously proposed the canonicalization proce...

The proliferation of digital images, and the widespread distribution of digital data that has been made possible by the Internet, has increased problems associated with copyright infringement on digital images. Watermarking schemes have been proposed to safeguard copyrighted images, but watermarks are vulnerable to image processing and geometric distortions, and may not be very effective. Thus,...

Serine-arginine-rich nuclear protein LUC7L plays an important role in the regulation of myogenesis in mice. In the present study, we isolated and characterized the Korean rose bitterling Rhodeus uyekii Luc7l cDNA, designated RuLuc7l. The RuLuc7l cDNA is 1,688 bp long and encodes a 364-amino-acid polypeptide containing serine/arginine-rich region at the C-terminus. The deduced RuLuc7l protein ha...

Let φ (z) be a fixed analytic and univalent function of the form φ(z) = z + ∑∞ k=2 ckz k and Hφ (ck, δ) be the subclass consisting of analytic and univalent functions f of the form f(z) = z + ∑∞ k=2 akz k which satisfy the inequality ∑∞ k=2 ck |ak| ≤ δ. In this paper, we determine the sharp lower bounds for Re { Dpf(z) Dfn(z) } and Re { Dfn(z) Dpf(z) } , where fn(z) = z + ∑n k=2 akz k be the se...
