During the Mediterranean Intensive Oxidant Study (MINOS) in August 2001 a total of 14 measurement flights were performed with the DLR Falcon jet aircraft from Heraklion, Crete. One objective of this campaign was to investigate the role of long-range transport of pollutants into the Mediterranean area. An analysis of 5-day back trajectories indicates that in the lower troposphere (0–4 km) air ma...

A programmable processor architecture for MPEG-4 video is proposed, that can serve as a coprocessor module in MPEG-4 decoder systems. It consists of a 64-bit dual-issue VLIW macroblock engine, a separate RISC core for bitstream parsing and system processing, and an autonomous I/O processor. A separate DSP is used for MPEG audio support. The architecture is fully programmable and supports parall...

Air samples were collected seasonally at Lake Small Baiyangdian, a shallow lake in northern China, between October 2007 and September 2008. Gas phase, particulate phase and dust fall concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured using a gas chromatograph-mass spectrometer (GC-MS). The distribution and partitioning of atmospheric PAHs were studied, and the major sources...

In this paper we present an enhancement of model-based trajectory selection algorithms – a popular class of collision avoidance techniques for autonomous ground vehicles. Rather than dilate a set of individual candidate trajectories in an ad hoc way to account for uncertainty, we generate a set of trajectory clouds – sets of states that represent possible future poses over a product of interval...

Fig mosaic disease (FMD) is a viral disease that spreads in all Tunisian fig (Ficus carica L.) orchards. RT-PCR technique was applied to leaf samples of 29 fig accessions of 15 fig varieties from the fig germplasm collection of High Agronomic Institute (I.S.A) of Chatt-Mariem, to detect viruses associated to FMD. Analysis results show that 65.5% of the accessions (19/29) and 80.0% (12/15) of th...

Holy Quran, the last religious reference book, describes the importance of various plants in different chapters (Sura). Herbs have always been the principal form of traditional medicine in some countries. In this review article, the authors attempted to describe the impact of one of the Quranic plants (fig) from medicinal aspects. This is a review article that was conducted using verses, reg...

The trajectory planning, which is known as a movement from starting to end point by satisfying the constraints along the path is an essential part of robot motion planning. A common way to create trajectories is to deal with polynomials which have independent coefficients. This paper presents a trajectory formulation as well as a procedure to arrange the suitable trajectories for applications. ...
