Evolving a logo design using Lindenmayer system.postscript and grammatical evolution

Creativity in Logo designing, one of the main indicators of graphic includes principles which are innate and intuitional to many graphic designers. But presupposition of this abstract is on the basis of acquirable creativity. The question is how strategies can be made to create visual ideas; creativity is put into challenge practically and academically.
In fact, the study of scientific and academic strategies to create different kinds of Logos out of ideas is the main objective of this paper. To this end, the author has tried to study this subject matter by the expert opinion and firsthand sources. This paper reviews definitions, aesthetic principals, creativity and some strategies theoretically.

The present study attempts to examine the relationship between emotional intelligence and students’ thinking styles in school district 13 of Tehran. The target population included all the high school students in this area 200 of which were selected for the purpose of this study. The method of this study was descriptive and correlational.The data were collected by field study and questionnaire. A questionnaire was used to measure the participants’ emotional intelligence which had 19 questions. In order to investigate the participants’ thinking styles, Sternberg and Wagner’s thinking styles inventory was used which has 40 questions and measures five thinking styles (legislative, judicial, executive, outward, inward). The collected data were analyzed by SPSS software using descriptive (frequency, mean and standard deviation) and inferential statistics (Pearson correlation coefficient, chi2, dependent-samples t-test). Reliability of the emotional intelligence questionnaire was found to be 0.78.The results showed that there was a meaningful relationship between emotional intelligence and thinking styles of boy and girl students; there was a difference between boys and girls in thinking style; there was also a significant difference between the two groups in emotional intelligence. The results pointed to the conclusion that emotional intelligence can highly influence thinking style. Therefore, authorities are recommended to arrange for proper training and educational programsin this regard for students to help them control their emotional intelligence and take appropriate measures forselecting the right thinking style.

This paper presents innovative computer software – AGROLOGIS, which supports decisions concerning the management of logistic costs of agricultural processes and products made by the managerial staff of agricultural enterprises. Process modelling was applied to develop this computer software. The research on the executed business and logistic processes was conducted on the farms whose area was larger than 500 ha, with mixed production. Furthermore, the enterprises under study had at least several production facilities. First the reference models of business processes and the logistic processes included in them were developed for individual agricultural products. The aim of the reference models was to determine all events generating costs in supply, production and distribution processes taking place in agricultural enterprises in reference to each product. The developed models were used in the system architecture to register the consumption of resources. Then the software architecture was developed. Its construction was supposed to enable the identification, analysis and calculation of the costs of logistics with the division into individual processes, products and places of cost generation. The developed computer application provides numerous operational and management reports. The reports specify the cost level in individual processes and in reference to particular products. Furthermore, the program generates logistic measures and efficiency and cost indexes, which provide a package of information supporting management decisions. The information obtained from the software enables the management staff to estimate the profitability of individual agricultural products and to study in detail the costs of logistic processes and costs of products.

A sensor network is an infrastructure comprised of sensing (measuring), computing, and communication elements that gives an administrator the ability to instrument, observe, and react to events and phenomena in a specified environment. Patients who have survived cardiac attack or other physiological problems are at a higher risk of sudden cardiac death. Many of these patients are living at home without any kind of cardiac monitoring systems.
By using a wearable monitoring system for detection of ECG systole, Diastole, Flux, Body temperature, Weight, Accelerometer, Latitude and Longitudinal location, it is possible to alert healthcare professional to the patient’s condition so that the necessary action for an emergency rescue can occur. A special purpose sensor network here, designed to operate autonomously to connect varies medical sensors placed on the human body. In this system, we effectively monitors the patients physiological status such as ECG, Body temperature, systole, diastole, Heartbeat, flex, Accelerometer and successfully processed in the transmitter kit, which is attached in the patients body. Effectively transmits the data from the transmitter kit through a GPRS to the receiver which is located in the hospital server. Hence the patients need not to be in observatory room or under any supervision of health care professionals, and the mobility will be greatly achieved in our work. .In addition to that we are tracking the patient’s location through GPS continuously, by obtaining the Latitude and longitudinal position can easily make emergency rescue operation. . Introduction of effective medical monitoring & other applications continuosly will offer flexibilities and cost saving options to both health care professionals and patients. Here, we produce an efficient, reliable, and secure platform that can meet increasing needs in e-healthcare applications. These applications require to support multiple data rates with reliable and energy efficient data transmission which can be achieved by our earlier developed Efficient and Secure Routing protocols (ESRP).

Eccentrically braced frames (EBFs) are known as both ductile and stiff systems with a large dissipative capacity. The use of EBFs as a primary system in dual systems is a possible way for improving the seismic response of separate EBFs or MFs. This paper discusses nonlinear behavior of two sample cases of 20 and 15-story EBF dual systems. For each case six structural configurations with different relative stiffness of MFs and EBFs, were designed and examined with nonlinear static and nonlinear dynamic procedures. Results indicate that the best combination occurs when almost 45% of lateral load is absorbed by MFs. The results show that dual systems have better seismic behavior than MFs or EBFs, separately. Also the period of EBF dual system and the effect of structure’s height on the period are discussed. To improve undesirable interaction between EBFs and MFs at top stories in the best structural configuration some methods were examined. Results show that any method that can decrease stiffness of EBFs at top stories will improve the undesired interaction.

Evaluation of IEEE 802.11 Mobile Ad Hoc Networks (MANET) security issues becomes significant concern for researchers since Denial of Service (DoS) attacks are recognized as one of the most harmful threats. Variety of security mechanisms are proposed to solve security dilemma in MANETs against different layers of DoS attacks. Physical Layer jamming attacks exhausts the victim’s network resources such as bandwidth, computing power, battery, etc. Unified Security Mechanism (USM) and Rate Adaptation Scheme (RAS) are two of the proposed methods by researchers against DoS attacks. In this research paper RAS and USM has compared in terms of performance metrics under physical layer jamming attacks through simulation experiment.
