RodentSQL: A software suite for colony management of animal protocols

Most of the mouse experiments tend to generate a large-scale data, which is needed to be stored and eventually made publicly available. Many research groups still struggle to have central storage and integrated management system of this metadata. Some existing tools like Microsoft excel sheets and couple other colony management web/cloud-based tools are either cumbersome or expensive. There seems a constant need for...

Creating E-pedigree Kanban to secure customers’ chain using multi-agent image technique

Egypt is one of the countries mostly faced with the problem of China’s fake spare parts used in replacing original components. The spare parts components trade is close to 2.7 billion LE out of 9.3 billion LE, that is, the volume of imported spare parts in Egypt, as announced by the official speaker of the Ministry of Trade and Industry in Egypt. Hence, it can be seen that China’s components adulteration...

Comparison and performance analysis of reactive type DSR, AODV and proactive type DSDV routing protocol for wireless mobile ad-hoc network, using NS-2 simulator

  Routing in MANET is a critical task due to highly dynamic environment. A routing protocol is needed whenever a packet needs to be transmitted to destination via number of nodes and numerous routing protocols have been proposed for ad-hoc network. In this paper we try to judge the impact of both reactive as well proactive type protocols by increasing the density of nodes in the network, keeping...

Optimization of spatial join using constraints based- clustering techniques

  Spatial joins are used to combine the spatial objects. The efficient processing depends upon the spatial queries. The execution time and input/output (I/O) time of spatial queries are crucial, because the spatial objects are very large and have several relations. In this article, we use several techniques to improve the efficiency of the spatial join; 1. We use R*-trees for spatial queries since R*-trees are...

New approaches to automatic headline generation for Arabic documents

  A headline is considered a condensed summary of a document. The necessity for automatic headline generation has been on the rise due to the need to handle a huge number of documents, which is a tedious and time-consuming process. Instead of reading every document, the headline can be used to decide which ones contain important and relevant information. There are two major approaches to automatic headline...

Interference reduction in mobile ad hoc and sensor networks

  There are still a lot of open questions in the field of mobile ad hoc networks (MANETs) and sensor networks. If a topology incurs a large interference, either many communication signals sent by nodes will collide, or the network may experience a serious delay at delivering the data for some nodes, and even consume more energy. So, we reach the conclusion that interference imposes a potential negative impact...

Commodity futures market mechanism: Mathematical formulation and some analytical properties

  This paper deals with the internal structure of a commodity futures market. We proposed a mathematical model representing the mechanism of this market. The model shows the links between market components (transactional prices, transactional quantities, open interest) and traders' states (position, position’s average price, potential wealth and realized wealth). Later, we stated and demonstrated some...

Scenario based performance analysis of reliant ad hoc on-demand distance vector routing (R-AODV) for mobile ad hoc network

  A mobile ad-hoc network (MANET) is a peer-to-peer wireless network, that is, nodes can communicate with each other without the use of infrastructure. Besides, nodes are free to join and/or leave the network at anytime, move randomly and organize themselves arbitrarily. Due to this nature of MANET, there could be some malicious and selfish nodes that try compromise the routing protocol functionality and make...

Sample reduction using recursive and segmented data structure analysis

  Support vector machine (SVM) is one of the widely used machine learning algorithms because of its salient features such as margin maximization and kernel substitution for classification and regression of data in a high dimensional feature space. But SVMs still face difficulties in handling large datasets. This difficulty is because of solving quadratic programming problems in SVMs which is costly, especially...

Construction and adjustment of differential polynomial neural network

  Artificial neural networks in general are used to identify patterns according to their entire relationship, responding to related patterns with a similar output of applying absolute values of variables. However, a lot of real data contain some unknown relations of variables. Learning of these dependencies could be a new way of modelling complex systems instead of usual time series prediction based on pattern...

Design of fuzzy PD-controlled overhead crane system with anti-swing compensation

  This work aimed to find a proper control strategy to transfer loads using overhead cranes. The proposed control strategy, which is Fuzzy PD-based, should take into account two main factors. First, the time needed to move the payload from the initial pick up point to the destination point that must be minimized. Secondly, the oscillation of the payload must be reduced to prevent hazards for people and...

Cooperative control and synchronization with time delays of multi-robot systems

  In this article, we investigate the cooperative control and global asymptotic synchronization of Lagrangian system groups, such as industrial robots. The proposed control approach works to accomplish multi-robot systems synchronization under an undirected connected communication topology. The control strategy is to synchronize each robot in position and velocity to others robots in the network with respect to...

Statistical modeling and computer simulation of corrosion growth in aluminum alloy

  An extension of a brick wall model was used to describe corrosion of aluminum alloys. The extended model simulates the behavior of corrosion paths at intersections of grain boundaries within the metal sample. Situations considered include the cases where a corrosion path might assume an upward turn, skip an intersection (not turn) or split into branches. The splitting of a corrosion path results in a smaller...
