  • In addition to the physical parameters such as magnetization intensity distribution, the volume and the shape of the magnetized material, directions of the magnetization and the ambient field, the distance between the observation surface and the causative sources significantly affects the shape and the amplitudes of the magnetic anomalies. Aeromagnetic surveys are performed using either a draped surface or a constant elevation plane above sea level. These surveys can easily reconnoiter large territories in a short time.

  • The sponge pores decorated with Au nanoparticles could effectively capture and concentrate microplastics in the pores from aquaes sample. Interestingly, the adjustable size of the sponge could allow the distance between the “hot spots” on the substrate surface to be controlled, hence controlling the SERS signal intensity.

  • Fractal analysis helped find differences in species in the organisation of fish otolith crystalline surfaces in 2 closely related and 2 distant species. To determine regularities of this organisation, we used the microcanonical method of multifractal spectra. It was revealed that the differences of multifractal spectra were more significant for longer distances of taxonomic divergence.

  • Silk fibroin, which has many characteristic properties such as low inflammation reaction, biodegradation, suppleness, good antithrombogenic details, biocompatibility and high tensile strength is a very good candidate for biomedical applications. Electrospinning procures high surface area, porous, nanofiber dimension fiber generation, which is a plain method. An experimental study was carried out to produce nanofiber structure from silk fibroin by electrospinning and the electrospinning parameters for the spinning of uniform, continuous and silk fibroin fibers were optimized.

  • Weeding is one of the major control operations in the vegetable crops. The traditional method of weed control is to remove the weed manually by a Khurpi or Spade. This is a very time consuming process. Due to shortage of agricultural labour in peak season, farmers cannot compete weeding in time. Mechanical weeding keeps the soil surface loose, which results in better aeration and moisture conservation. In our country the average land is about 0.

  • Non-covalent interactions in term of hydrogen bond in complexes of chloroform with hydrogen cyanide and its fluoride derivative were investigated thoroughly by scanning the potential energy surface. The complexes of both examined systems show blue-shift at their most stable geometries. All of systems experience the contraction in C-H bond length at long distances. At specific RN-H distance, the C-H bond of CHCl3 molecule in complexes with FCN tends to be more blue-shifted than one in connection with HCN counterpart.

  • We introduce an inclusion-field technique for fast detection of collisions between a highly deformable object and another object with limited deformations. We mainly target the cloth simulation application where cloth (highly deformable) collides with deforming skin of a moving human model (has limited deformation as skin stretches and compacts within finite spacial and temporal limits specified by the bending angle and speed). Our technique intermixes concepts from space voxelization and distance fields to make use of the limited deformation nature of human skin.

  • The western termination and total length of the earthquake rupture is still a matter of debate because the surface rupture goes off shore in the Gulf of İzmit after displaying a coseismic displacement of ~5 m. Such a considerable slip implies that the fault rupture must definitely continue some distance westward on the sea floor, but where exactly it terminated is difficult to determine.

  • We introduce an alternative approach to extracting word pair associations from corpora, based purely on surface distances in the text. We contrast it with the prevailing windowbased co-occurrence model and show it to be more statistically robust and to disclose a broader selection of significant associative relationships - owing largely to the property of scale-independence. In the process we provide insights into the limiting characteristics of window-based methods which complement the sometimes conflicting application-oriented literature in this area. ...

  • South-east Asian components of our population are increasing rapidly. The ethnic mix in each organisation is likely to be quite different, so the best approach may be to develop anthropometric distributions for each organisation from different data sets, using the proportions of each ethnic group. Some applications of anthropometric data are discussed below. The arrangement of equipment on a working surface should be based on placing the most frequently used items within the easiest reach.

  • In this paper, we focus our attention on providing a formal framework for expressing data mining tasks in- volving time granularities, and on proposing efficient algo- rithms for performing such tasks. To this end, we introduce the notion of an event structure. An event structure is essen- tially a set of temporal constraints on a set of variables representing events. Each constraint bounds the distance between a pair of events in terms of a time granularity.
