Abstract Several assessing efforts are approved making both communication and information technologies available. In addition to being a part of universal access and service, we aim at assessing the impact of radio access technologies on universal access indicators. The proposed work demonstrates the possibility of inter-working of all existing Radio Access Technologies (RATs), in a limited area presented in the Six Generation Radio Resources Allocation (6 G-A) network. We propose a solution for the Vertical hand Over (VHO) in 6 G-A heterogeneous system, that adopts Media Independent Handover (MIH) protocol to benefit between different used technologies… More >

Abstract This paper describes a real-time simulator that allows the user in the factories to simulate arbitrary interaction between machinery and equipment. We discussed in details not only the general technique for developing such a real-time simulator but also the implementation of the simulator in its actual use. As such, people on the production line could benefit from observing and controlling robots in factories for preventing or reducing the severity of a collision, using the proposed simulator and its related technique. For that purpose, we divided the simulator into two main models: the real-time communication model More >

Abstract Achievement of sustainable privacy preservation is mostly very challenging in a resource shared computer environment. This challenge demands a dedicated focus on the exponential growth of big data. Despite the existence of specific privacy preservation policies at the organizational level, still sustainable protection of a user’s data at various levels, i.e., data collection, utilization, reuse, and disclosure, etc. have not been implemented to its spirit. For every personal data being collected and used, organizations must ensure that they are complying with their defined obligations. We are proposing a new clustered-purpose based access control for users’… More >

Abstract The multi-purpose forensics is an important tool for forge image detection. In this paper, we propose a universal feature set for the multi-purpose forensics which is capable of simultaneously identifying several typical image manipulations, including spatial low-pass Gaussian blurring, median filtering, re-sampling, and JPEG compression. To eliminate the influences caused by diverse image contents on the effectiveness and robustness of the feature, a residual group which contains several highpass filtered residuals is introduced. The partial correlation coefficient is exploited from the residual group to purely measure neighborhood correlations in a linear way. Besides that, we… More >

Abstract The wheat vernalization response is controlled by three recessive alleles identified and located, that allows to characterize varieties through genetic analysis. However, it is unknown whether the same genetic constitution at a loci scale in different varieties implies the same (1) requirement of cold hours, and (2) interaction with the photoperiod for induction. Therefore, we conducted an experiment with varieties carrying the alleles (vrn-A1, vrn-B1 vrn-D1), extreme condition of vernalization requirements, to compare the duration of the vegetative phase under different photoperiods. The study was conducted in a greenhouse with four varieties of double purpose wheat.… More >

Abstract This study aimed to characterize wheat cultivars for their chilling requirements for differentiation and their relationship to flowering time, to establish a dual purpose ideotype. Seeds of eight genotypes (cultivars and advanced lines) of bread wheat were exposed to constant temperature (4 °C) in germination chambers for 8, 6, 4 and 2 weeks. A control treatment was kept at room temperature. Four replicates of each treatment were placed in the greenhouse in 250 cc pots containing 4 seedlings each, with irrigation and natural photoperiod, following a randomized complete block design. The greenhouse temperature was constant… More >

Abstract Here we develop a general purpose pre/post conditionerT, to solve an ill-posed system of linear equations,Ax=b. The conditionerTis obtained in the course of the solution of the Laplace equation, through a boundary-collocation Trefftz method, leading to:Ty=x, whereyis the vector of coefficients in the Trefftz expansion, andxis the boundary data at the discrete points on a unit circle. We show that the quality of the conditionerTis greatly enhanced by using multiple characteristic lengths (Multiple Length Scales) in the Trefftz expansion. We further show thatTcan be multiplicatively decomposed into a dilationTDand a rotationTR. For an odd-orderedA, we More >

Abstract Forage and grain production of an early sown, long-cycle wheat variety (ProINTA Super) was compared to that in its association with a short-cycle wheat variety (Buck Pronto), both varieties exposed to one or two defoliations. The purpose was producing an earlier and greater amount of dry matter in a dual-purpose wheat. Research was conducted in the Asociación de Cooperativas Argentinas experimental field (38º 36´ S, 61º 58´ W, 122 masl), 15 km SW from Cabildo (Bs. As), in the semi-arid V South wheat subregion. Experimental plots, 7 rows 4m long each and 0,20 m apart… More >

Abstract In mixed systems (beef and grain), double purpose wheat is an alternative to reduce competition between the winter cereals for grazing and wheat for harvesting. In order to optimize grass production and avoid grain yield decreases, it is necessary to use varieties with long vegetative periods and the last defoliation should be made before the apex changes to the reproductive developmental stage. A study was conducted in the experimental field of the Asociación de Cooperativas Argentinas in Cabildo (38º 36' S, 61º 58' W) to evaluate grass and grain production of the facultative wheat variety (Triticum… More >

Abstract Length of the vegetative period and forage production were evaluated in ten commercial, long term cycle wheat varieties: Buck Charrúa, Cooperación Nanihué, Buck Cacique, Cooperación Maipún, Buck Catriel, ProINTA Pigüé, Buck Poncho, ProINTA Pincén, ProINTA Super and Cooperación Liquén. The study was conducted in the experimental field of the Departmento de Agronomia, Universidad Nacional del Sur, Bahía Blanca, Argentina, under dry land conditions. A completely Randomized Block Design with five replicates was used. Seeding was effected on 9 April 1996. From the time the plant had three leaves to the Double Ridge (DA) apex stage,… More >
