“…It is also important to incorporate structures such as jump-outs into fencing designs to allow animals that breach the barrier to return to safety (Huijser et al 2009). Iran’s Ministry of Roads and Urban Development is planning on fencing 12 km of the Shahroud-Sabzevar Highway over the next two years to secure the most dangerous section of the highway (Abdollahpour 2017). While we welcome this development, we recommend that fencing should be integrated with wildlife crossing structures to ensure landscape connectivity.…”

“…Wildlife warning signs that are spatially- and temporally-specific are more likely to be effective at reducing roadkills (Huijser et al 2015). Iran’s Ministry of Roads and Urban Development will install 25 wildlife warning signs with flashing lights before and after the 12 km fences on the Shahroud-Sabzevar Highway to reduce road mortalities involving cheetahs (Abdollahpour 2017). Flashing lights, however, cannot be considered an effective measure unless very low vehicle speeds (i.e.…”

“…comm.). Iran's Ministry of Roads and Urban Development is planning on implementing traffic calming measures before and after the 12 km fences on the Shahroud-Sabzevar Highway to reduce road fatalities involving cheetahs (Abdollahpour 2017). However, we do not recommend this measure since it could be largely ineffective.…”

Wildlife-vehicle collisions are an important cause of mortality for many species, and the number of collisions is expected to grow rapidly as the global road network quickly expands over the next few decades. Wildlife-vehicle collisions also have the potential to be extremely detrimental to small wildlife populations, such as the critically endangered Asiatic cheetah (Acinonyx jubatus venaticus), with only 43 individuals remaining in the wild. We assessed the spatial distribution of road mortalities between 2004 and 2016 to identify roadkill hotspots involving Asiatic cheetahs in Iran using network kernel density estimation. A total of sixteen cheetah fatalities due to wildlife-vehicle collisions were recorded, and we identified six road fragments as roadkill hotspots. Efforts to reduce wildlife-cheetah collisions should be targeted in the densest hotspots. We review the options available to achieve this, and we recommend a strategic shift away from the ineffective warning signage currently used, and instead suggest adopting an evidence-based approach focusing on installing wildlife crossing structures in conjunction with fencing in roadkill hotspots. These measures will help to enhance the conservation status of the Asiatic cheetah, as the current high level of mortality of Asiatic cheetahs on Iran’s roads could have potentially dramatic impacts on this critically endangered subspecies.

This Today's world depends upon utilization of some form of energy. Be it use of mobiles, vehicles, power supply in houses etc., everything functions on the basis of energy input. The use of energy derived from fossil fuels began in early 1800 and is used till date. In the current theme that calls for saving energy and reducing pollution, it’s undoubtedly of great significance to make full use of solar energy. The solar panel system sprouted with the use of a simple magnifying glass to concentrate solar energy which has now revolutionized by using a much higher solar panel system. The framework consists of webcam, electronic circuit, Microprocessor and two DC motors. This solar tracking system is autonomous, dual axis and hybrid type. This tracking system is camera-based and can track the sun continuously. By using Region of Interest algorithm, we can get the sun coordinates from the frame. These values are sent to the microcontroller to actuate the motors and reposition the panel. This framework works free of its primary settings and can be utilized in any geological area. It holds the solar panel opposite to illumination of sun to get the most extreme solar energy and hence produce most effective power yield for the duration of the day. This study yields an output of up to 2-3% increase from a stationary solar panel.

Main challenge of solar-tracking systems are the sunlight detection, providing position and delay of PV movement, designing control module for low consumption dc servo motor(s). Objective of this paper is designing and implementing automatic control for detecting maximum solar light to a solar panel. The two-axis solar tracker is used for optimizing conversion of solar energy into electrical energy, at cost of the mechanical and the maintenance need, for the best efficiency. The hardware development, two dc servomotors are adjusted which is controlled by drive module moving panel by using four Light-Dependent Resistor (LDR) to provide the analog signals; the signals are processed by ATMEGA328P micro-controller with Arduino.
