Artificial lighting accounts for approximately twenty to twenty five percent of all electrical energy usage in the United States. This is surpassed only by the energy consumption of electric machinery. Artificial lighting is a requisite for virtually all activities in residential, commercial, and industrial settings. Whether it is in the area of design, manufacture, application, maintenance, or...

— In the area of distributed systems, there is a segment gaining more importance due to recent development in hardware and software technology. This is the area of home networking. Its target is making inhabitants get more and more comfortable. Comfort system may be considered as value-added services. They can be: the remote access and automatic control of appliances, the surveillance of the ho...

LED-based lighting systems have introduced radically new possibilities in the area of artificial lighting. Being physically small the LED can be positioned or embedded into luminaires, materials and even the very fabric of a building or environment. Together with new functionality and flexibility comes complexity; the simple light switch is not anymore sufficient to control our light. This work...

The specific objective of this paper is to develop a computer vision algorithm to detect and count tangerine flowers in an image for estimate tangerine crops. The algorithm consists of image acquisition, Gaussian filter to remove noise, white color detection, counting of tangerine flowers. A Gaussian filter was used to reduce noise and illumination adjustment as much as possible for better clar...

Estimating the contribution of a blurred photon plane involves the computation of an integral along the interval of overlap between the camera segment and the photon plane. In order to reduce variance introduced by this estimation, we apply control variates [Glasserman 2003] in our implementation of the photon plane estimator for homogeneous media. The concept of control variates is simple. Say...

Reducing energy consumption without compromising the quality of products in a pharmaceutical manufacturing environment and maintaining the comfort of employees is of critical important in maintaining the financial viability and competence of the company. Heating, Ventilation and Air Conditioning (HVAC) system was identified as the major energy consumer in both office building and manufacturing ...

lighting plays a key role in night escapes of urban spaces, in a way that it can be effective in giving identity to them. by considering this importance and inexistence of a process for composing urban lighting strategy made this study to be conducted by the objective of providing process for compilation of context-oriented lighting strategy in urban spaces. reaching a suitable solution for lig...
