[Article Title: Design and implementation of a wirelessly controlled object carrying hexacopter / Ifthekhar Ahammad, Ariful Alam, Neyamul Islam, Jamil Sorowar and Mowdud Ahmed, p. 1-11]

Abstract: Unmanned aerial vehicle (UAV) is becoming the future of remote operation, monitoring and delivery system. For a UAV, remote operation requires a versatile control system that can maintain its position without disturbing the task at hand. This paper introduces a hexacopter which is able to pick and place an object by using a robotic arm, while it is flying. The arm is used to grip an object firmly and carry it to the desired destination. It maintains its position on air accurately while performing the pick and place operation. This UAV is able to withstand windflaw to maintain its position. This project can be used for rescuing, transportation of products, first aid supply etcetera.

[Article Title: Intelligent web search system for personalised web search based on recommendation of web page communities / Suruchi Chawla, p. 12-30]

Abstract: In this paper an intelligent web search system is proposed based on recommendation of web page communities for personalised web search (PWS). Web page communities are set of web pages that provide the good quality resource on a given topic. The intelligent search system adapts the web search to the user's information need based on recommendation of web page communities. The groups of similar content clicked web pages in clusters are selected for generation of web page communities using maximum flow algorithm with hyperlink-induced topic search (HITS). The cluster of web page communities is selected for recommendations of relevant web pages to user during web search for effective web information retrieval.

[Article Title: Functional implementation of EEDR routing protocol in wireless sensor networks / M.S. Pramod and Shiva Shankar, p. 31-48]

Abstract: Wireless sensor networks (WSN) are having high attention since there are huge developments and vast applications in the military and environmental applications. In this paper, the software implementation of energy efficient distributed receiver (EEDR) based protocol for WSN using MATLAB is discussed. The proposed mechanism uses information related to channel information, transmission range of sensor nodes and minimum hop. The main objectives of the proposed work include: 1) reduced delay; 2) reduced control packet overhead; 3) increased throughput; 4) high residual energy of all nodes in the network.

[Article Title: Regression-based software fault prediction using biogeography-based optimisation (R-BBO) / Aarti, Geeta Sikka and Renu Dhir, p. 49-63]

Abstract: It is difficult to build model of accurate estimate due to the inherent uncertainty and similarity among different categories in development projects. In this paper, fault prediction is done using biogeography-based optimisation (BBO) with the goal of recognising the faults in software systems in more efficient way. Our methodology includes four steps as follows: 1) firstly pre-processing was employed to remove redundant data; 2) secondly, relevant features are extracted using principal component analysis; 3) thirdly, fault-prediction system based on the optimisation of regression parameter using biogeography-based optimisation (R-BBO) was proposed.

[Article Title: Energy efficient routing protocol for wireless sensor networks using dynamic hyper round policy and ACO / Navin G. Haswani; Pramod J. Deore, p. 64-83]

Abstract: The clustering based routing protocols enhance the performance and scalability of wireless sensor networks (WSNs). State-of-art routing methods perform clustering and cluster head (CH) based on the scheme of fixed time intervals. Repetitive task of the cluster formation and CH selection at each time interval, regardless of its necessity, leads to routing overhead and consumption of network energy. Along with clustering, efficient route formation is a challenge to WSN routing protocols. In this paper, an attempt is made to overcome these challenges based on dynamic hyper round policy and route optimisation strategy.

[Article Title: Adding context to Concept Trees / Kieran Greer, p. 84-100]

Abstract: A Concept Tree is a structure for representing knowledge, where the trees are stored in a Concept Base. It sits between the highly distributed neural architectures and the distributed information systems, with the intention of bringing brain-like and computer systems closer together. Concept Trees can grow from unstructured or semi-structured sources when consistent sequences are presented. Each tree ideally represents a single cohesive concept and the trees can link with each other for navigation and semantic purposes. A consistent build process is managed through a 'counting rule' and mathematical basis that can normalise the database structure. This restricted structure can then be complimented and enriched by a more dynamic context. A number of tests have demonstrated the soundness of the architecture, which may be inherent in natural language. Two types of query language are also described that can answer knowledge-based questions and even enhance the query with new knowledge.
