Semantic Aware Multi-Agent System Advantages
Get PDFInternet changes the way people communicate with each other and also affects the business flow. Technology changes affect how people live and communicate with each other, but they themselves also transform and become more human like. The agent oriented programming and multi-agent systems are relatively new example technologies that manifest these changes in a multifacet way. The goal of this paper is to explore the possibilities one can obtain by combining multi agent systems with the emerging semantic web technologies. This powerful combination leads towards new types of complex system development. Using a case study example, together with a comparison with the traditional system design approach, the paper also discusess the possibilities of semantic agent platforms and their development and shows how developers can benefit from following the standards to agent development

Optimal Cluster Head selection in Wireless Sensor Networks using Integer Linear Programming Techniques
Get PDFWireless sensor network (WSN) consists of sensor nodes which are deployed in the environment densely and randomly. The main constraint of these nodes is limited energy resources, so, the operations which are performed in the network, must be energy efficient. For this reason, routing and data transmission in these networks perform hierarchically and in multi hop manner. One of these hierarchical architectures which have a considerable positive effect on energy consumption is clustering algorithm. But what is important is that the cluster heads election should be done efficiently. Recently some works have focused on optimal cluster head election using Integer Linear Programming techniques. In this paper, Integer Linear Programming techniques are used to formulate the clustering problem. At first, by using Integer Linear Programming techniques, a scalable and multi objective model for optimal cluster head selection is presented and then the distributed clustering algorithm is proposed. As shown in simulation results, the proposed clustering algorithm is more efficient in terms of energy vs. LEACH algorithm

In order to select the students to participate in this program, STMIK STIKOM of Surabaya uses EPPS psychological test which can measure the achievement, deference, autonomy, affiliation, nurturance, and endurance of CO-OP participant. The used of EPPS psychological test is based on the reason that this test is one of the personality tests prepared to measure the power of someone’s need. By the existence of EPS application in selecting CO-OP participant, a proper result’s validity is expected to be reached
Fast Data Acquisition of Aerial Images Using Unmanned Aerial Vehicle System
Get PDFThe present work discusses the technique and methodology of analysing the potential of fast data acquisition of aerial images using unmanned aerial vehicle system. This study utilizes UAV system for large scale mapping by using digital camera attached to the UAV. UAV is developed from the low-altitude photogrammetric mapping to perform the accuracy of the aerial photography and the resolution of the image. The Ground Control Points (GCPs) and Check Points (CPs) are established using Rapid Static techniques through GPS observation for registration purpose in photogrammetric process. The GCPs is used in the photogrammetric processes to produce photogrammetric output while the CP is employed for accuracy assessment. A Pentax Optio W90 consumer digital camera is also used in image acquisition of the aerial photograph. Besides, this study also involves image processing and map production using Erdas Imagine 8.6 software. The accuracy of the orthophoto is determined using the equation of Root Mean Square Error (RMSE). The final result from orthophoto is compared to the ground survey using total station to show the different accuracy of DEM and planimetric survey. It is discovered that root mean square errors obtained from UAV system are ± 0.510, ± 0.564 and ± 0.622 for coordinate x, y and z respectively. Hence, it can be concluded that the accuracy obtained from UAV system is achieved in sub meter. In a nutshell, UAV system has potential use for large scale mapping in field of surveying and other diversified environmental applications especially for small area which has limited time and less man power

Get PDFProviding patients with convenient health facilities at a low cost has always been a great challenge for health service providers. Moreover, the fast changing life style of the modern world and the problem of aging society pose an urgent need to modernize such facilities. The emphasis has to be paid on providing health monitoring in out-of-hospital conditions for elderly people and patients who require regular supervision, particularly in remote areas. This paper presents a recommendation algorithm, which incorporates collaboration and classification techniques in order to generate recommendations and suggestions for the physical activities that the users should carry out in order to improve their health. The algorithm has been evaluated using generic data and considering the daily food intake. The results of the experimental evaluation show that the algorithm is robust and could suggest the physical activities that might compensate the influence of the food intake over the blood glucose level
An Empirical Study on the Relation Between Types of Innovations: Pardis Technology Park as a Case Study
Get PDFNowadays, Innovation is known as an essential component of competitiveness, classified in different types in literature. For instance, on one hand it is classified based on OECD as product, process, marketing and organizational innovations and on the other hand as incremental, competence developing, market developing and radical ones based on the degree of internal and external newness. Also, innovation models have changed from “simple linear” to “networking interactions” and concepts such as ‘open innovation’ and ‘innovation network’ have become important to both academic and market society due to intensive global competition. Therefore, this paper tried to empirically study and analyze the types of innovation based on OECD regarding to other classification based on the degree of internal and external newness in a networking interaction. Thus, in order to empirically explore the relations between these two classifications, we used the data of last three years (2008-2011) of 50 companies from the network Pardis Technology Park (PTP) in Iran as a case study. The results showed that most of the innovations as product, marketing and organizational were new to the market. Also marketing and process innovations were more related to radical and incremental innovation respectively and less organizational innovations were incremental
