چکیده
Let A, B, be finite subsets of an abelian group, and let G ⊂ A × B be such that #A, #B, #{a + b : (a, b) ∈ G} ≤ N. We consider the question of estimating the quantity #{a − b : (a, b) ∈ G}. In [2] Bourgain obtained the bound of N 2− 1 13 , and applied this to the Kakeya conjecture. We improve Bourgain's estimate to N

یافته علمی کوتاه: کارآیی تور گوشگیر ثابت با چشمه 170 میلیمتر در کاهش میزان صید ماهیان نارس تاسماهی ایرانی (Acipenser persicus)
This study was carried out in Turkmen fishing station to examine suitable mesh size of gill nets for Persian sturgeon, Acipenser persicus, to decrease possibility of catching immature specimens and increase catch likelihood for larger fish. The Holt model was used to determine suitable length for catch and selection of mature Persian sturgeon females. Following preliminary studies some 920 expe...
متن کاملFrequency of illegal abandoned gillnets in the coastal waters of Golestan Province
Gillnets are sometimes abandoned or lost at sea due to sea storms, tearing by a hard object, or the failure of fishermen to find the fishing area. In this study, the data related to the frequency of illegal abandoned fishing nets in Golestan province were collected through field patrols and questionnaire information from spring to winter 2016. 88,465 abandoned fishing nets were collected in the...
متن کاملSelectivity of multifilament trammel nets of different mesh sizes on the red mullet (Mullus barbatus L., 1758) in Western Mediterranean, Turkey
Three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in Finike bay for red mullet (Mullus barbatus L., 1758). The sampling program was arranged during February to May 2012. Holt (1963) method was used for selectivity of trammel nets. Red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...
متن کاملNETS AND SEPARATED S-POSETS
Nets, useful topological tools, used to generalize certainconcepts that may only be general enough in the context of metricspaces. In this work we introduce this concept in an $S$-poset, aposet with an action of a posemigroup $S$ on it whichis a very useful structure in computer sciences and interestingfor mathematicians, and give the the concept of $S$-net. Using $S$-nets and itsconvergency we...
متن کاملUsing Interval Petri Nets and Timed Automata for Diagnosis of Discrete Event Systems (DES)
A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...
متن کاملA rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
