In tropical areas of China, energy saving is an important part architectural design, and the energy-saving potential residential buildings has attracted extensive attention. This paper studies daylighting, ventilation, building consumption in to find out best performance parameters. The model established by grasshopper, parameters ventilation cooling load are simulated. octopus plug-in grasshop...

Networks are strained by spam, which also overloads email servers and blocks mailboxes with unwanted messages files. Setting the protective level for spam filtering might become even more crucial users when malicious steps taken since they must deal an increase in number of valid communications being marked as spam. By finding patterns communications, detection systems (SDS) have been developed...

Motivated by a geometrical Thue-type problem, we introduce a new variant of the classical pattern avoidance in words, where jumping over a letter in the pattern occurrence is allowed. We say that pattern p ∈ E+ occurs with jumps in a word w = a1a2 . . . ak ∈ A+, if there exist a non-erasing morphism f from E∗ to A∗ and a sequence (i1, i2, . . . , il) satisfying ij+1 ∈ {ij + 1, ij + 2} for j = 1...

The Object Management Group (OMG) have defined mechanisms to support the persistence of CORBA objects with both the now deprecated Persistent Object Service (POS) and the new Persistent State Service (PSS). In this paper we describe both specifications and show that they are deficient in a number of areas. We introduce an alternative CORBA persistence mechanism that makes use of a novel persist...

A study was conducted to evaluate the influence of weather (precipitation and temperature) and plant communities on grasshopper density over a 14-year period (1996-2009) in Benito Juárez County, Southern Pampas, Argentina. Total density strongly varied among plant communities. Highest values were registered in 2001 and 2003 in highly disturbed pastures and in 2002 and 2009 in halophilous grassl...

Current theory on trophic interactions in food webs assumes that ecologically similar species can be treated collectively as a single functional unit such as a guild or trophic level. This theory implies that all species within that unit transmit identical direct and indirect effects throughout the community. We evaluated this assumption by conducting experiments to compare the direct and indir...

Over the last 15 years a number of persistent language systems have been produced whose implementation relies on the persistence mechanisms provided by an underlying operating system. We have produced an operating system called Grasshopper expressly designed to support orthogonally persistent systems. In this paper we demonstrate how the mechanisms provided by Grasshopper may be used to impleme...

The timing of application for the management of rangeland grasshoppers (Orthoptera: Acrididae) is critical, especially as insecticides become more specialized and the use of Insect Growth Regulators becomes more widespread. The general seasonal occurrence of adults of many grasshopper species has been well documented; however, their appearance varies widely between years. We analyzed sweep samp...

in order to improve the knowledge of the caelifera species of north eastern iran, faunistic investigations on grasshoppers of this region were carried out during 2013-2014. collected specimens as well as deposited specimens in insect museum of ferdowsi university of mashhad were examined, in detail. totally 19 species belonging to 17 genera, 9 subfamilies and 3 families were collected and deter...

In the past few years there has been an enthusiastic interest in mobile agent technology and several platforms have been developed. Some of them have only been used for research purposes while others have been deployed as commercial products. The community is now looking for applications where these platforms can be effectively used. Some comparisons about the functionality of some mobile agent...
