Impact of smart irrigation systems and water management on climate change

As a result of the rapid and unconscious consumption of existing natural resources in the world, climate change is accelerating negatively. It should be remembered that changing of climate has the potential to threaten the security of water, food and energy systems. One of the main problems causing this is improper water management. In this article, the effects of smart irrigation systems, which are a product of climate-smart agriculture and water management for the changing climate in the world, are reviewed in the literature and the effects of these systems on climate change are discussed. The aim of the study is to provide appropriate solutions against climate change. Water management is basically about being conscious of saving by making more use of irregularly used water resources and reducing wastage to zero in both agriculture and drinking water. Climate-friendly agriculture is practices that ensure sustainability in agriculture with climate resilience. Smart irrigation is a technological irrigation system applied to remotely control irrigation with artificial intelligence and minimize water waste. Considering that water resources will deplete more rapidly over time in the fight against climate change, necessary measures should be taken to minimize this loss

Semantic Edge Caching and Prefetching in 5G

Recent popularity of mobile devices increased the demand for mobile network services and applications that require minimal delay. 5G mobile networks are expected to provide much lesser delay than the present mobile networks. One of the conventional ways for decreasing the latency is caching the content closer to the end user. However, currently deployed methods are not effective enough. In this work-in-progress paper, we propose a new astute caching strategy that is able to smartly predict subsequent user requests and prefetch necessary contents to remarkably decrease the end-to-end latency in 5G systems. We employ semantic inference by mobile edge computing, deduce what the end-user may request in the sequel and prefetch the content

Power characteristics of a new contactless piezoelectric harvester

4th International Conference on Electric Power and Energy Conversion Systems, EPECS 2015 -- 24 November 2015 through 26 November 2015 -- -- 118937This paper reports the preliminary results of a new designed harvester system called as the contactless piezoelectric wind energy harvester (CPWEH). It consists of three piezoelectric layers attached with the non-magnetic bars in different lengths in order to produce maximal power for a wide wind wide speed regime. Preliminary magnetic design has proven that three layers can be excited by the magnetic forces synchronously and this situation prevents to damage the piezoelectric layers since it does not make any physical contact to the layer. According to the results, this new harvester produces electrical power at low wind speeds such as 2.5 m/s. The harvested power can be obtained from the range of 2.5 mW to 17 mW. Therefore the efficiency of the harvester having a single piezoelectric layer has been introduced three times in the proposed design and implementation. © 2015 IEEE.Türkiye Bilimsel ve Teknolojik Araştirma KurumuThis research has been supported by The Scientific and Technological Research Council of Turkey (TUBITAK) under grant EEEAG-114E017
