there are many reports of serious problems of dust storm events in the western parts of iran. based on many researches, iraq is one of the main sources of dust storms in western parts of iran. the radial basis function network (rbfn) model has been used to assess wind erosion hazard in iraq as a main source area of dust storms over several western cities of iran. the percentage of vegetation is...

Global maps of science can be used as a reference system to chart career trajectories, the location of emerging research frontiers, or the expertise profiles of institutes or nations. This paper details data preparation, analysis, and layout performed when designing and subsequently updating the UCSD map of science and classification system. The original classification and map use 7.2 million p...

Compression can be achieved by exploiting knowledge both internal and external to a given image or video source. In this paper, we present means for generating and exploiting the specific external knowledge of a 3D stereoscopic depth map of the given scene to compress the given monoscopic source. Several instances in which the depth map can potentially increase compression or provide improved f...

This paper introduces the LiDAR compass, a bounded and extremely lightweight heading estimation technique that combines a two-dimensional laser scanner and axis maps, which represent the orientations of flat surfaces in the environment. Although suitable for a variety of indoor and outdoor environments, the LiDAR compass is especially useful for embedded and real-time applications requiring low...

Adult sea turtles of several species migrate across vast expanses of ocean to arrive at specific nesting areas and feeding sites. Two hypotheses have been proposed to account for this remarkable navigation. The first is that chemical cues emanating from target areas guide turtles to their destinations. The second is that turtles can approximate their position relative to target regions using fe...

[1] The southern flanks of the central Nepalese Himalaya correspond to a sharp transition in landscape morphology and bedrock mineral cooling ages that suggests a change in rock uplift rate. This transition can be explained by either (1) accretion of footwall material to the hanging wall across a ramp in the décollement separating India from Eurasia, thereby enhancing rock uplift rates above th...

Transaction States In our model of transactions, an update transaction, once started, updates the abstract database atomically when the transaction commits, or makes no changes in the database, when it aborts. We have represented the global state of update transactions by a variable transstatus in the abstract model of the transactions. The variable transtatus is defined as transtatus ∈ trans →...

Joint source-channel decoding based on residual source redundancy is an e ective paradigm for error-resilient data compression. While previous work only considered xed rate systems, the extension of these techniques for variablelength encoded data was recently independently proposed by the authors [6], [7] and by Demir and Sayood [1]. In this paper, we describe and compare the performance of a ...

In areas where groundwater overexploitation occurs, land subsidence triggered by aquifer compaction is observed, resulting in high socio-economic impacts for the affected communities. In this paper, we focus on the Konya region, one of the leading economic centers in the agricultural and industrial sectors in Turkey. We present a multi-source data approach aimed at investigating the complex and...
