Sustainable design aims to reduce the negative impacts either on people (e.g., create healthy) or on planet (e.g., minimize waste). In other words, sustainable design is the philosophy that tends to improve design performance by incorporating health and safety attributes (for people), and environmental attributes (for planet) into products. In this paper, we develop an analytical model to exami...

IR active jammers or the directed infrared countermeasures(DIRCM)generate IR signals which attack the guidance signals passed to the sensors in IR-guided weapons. They provide IR signals with appropriate frequency, phase and intensity which will be superposed on those produced by the IR energy of the target passing through the reticle. When both the jamming signal and the modulated target energ...

Task groups focused on helping a single group member perform well on a task, or the advice-seeking situation, is a familiar occurrence in everyday life: patients and physicians work together to help the patient manage his or her quality of life, students and teachers work together to ensure that the student achieves academic success, and lawyers meet with clients to organize evidence in favor o...

The development of modern air defense missile systems requires robust simulations to adequately place margins on hardware and software design. Coupled with this is the need to accurately model surface reflections that constitute clutter to the missile system. A thorough understanding of these reflections is becoming increasingly important as the air defense threat evolves from large, high-altit...

Multilevel thresholding is one of the most popular image segmentation techniques. This paper presents a new multilevel maximum entropy thresholding method based on modified seeker optimization (MSO) algorithm. In the proposed method the thresholding problem is treated as an optimization problem and solved by using the MSO metaheuristics. Particle swarm optimization (PSO) algorithm is also imple...

On the Internet today, a type of customer called “Information Seeker” may develop more easily, who tries to gather independent sources of information about different products prior to purchase and thus makes a deliberate selection rather than trusting sellers or brands. Therefore, the function of brands in transmitting information will lose significance, with enormous impact on brand loyalty, e...

The flight environment of the Standard Missile, Block IV A interceptor involves high speeds that place severe aerodynamic and aero-thermalloads on the missile optical window and sensor. The supersonic flow over the missile produces aero-optical effects that can degrade IR seeker performance. This report summarizes an analysis of aero-optical aberrations due to shock front and shear layer densit...

This article presents a method for new ideas selection, which uses clustering to filter while considering the seeker’s goals and learning dynamics. Most of previous research has considered idea provider as main subject analysis. Instead, we focus on bounded rationality solution seeker. Seekers often estimate that cost an challenge comes from reward itself; yet, making mistakes in selection proc...

People-Finder Systems are knowledge repositories that attempt to manage knowledge by holding pointers to experts who possess specific knowledge within an organization. This paper presents insights from the development of Expert Seeker, an organizational People-Finder KMS that will be used to locate experts at the National Aeronautics and Space Administration (NASA). This paper discusses insight...
