The challenge of increasing crop yield to suffice the food demand is being addressed by using modern technology in agriculture or by implementing a Smart Farm. Irrigation plays a very important role in Smart Farm but also requires optimized operating conditions to maintain sufficient water supply while ...
Underwater acoustic communication channels suffer from many problems, such as limited bandwidth, propagation delays, Doppler shifts, time-varying nature and multipath fading. To reduce the effect of fading and time-varying nature of the underwater communication channel, a new Differential Frequency ...
Prediction is one of the most complicated and challenging tasks; if it comes to tidal prediction then it becomes more complicated because of the chaotic nature of gradual increment in water level. Since Bangladesh is a low lying land, performing tidal prediction in seaport area is really a key factor ...
Animals choosing particular display sites often balance sexual and natural selection pressures. Here we assess how physical properties of display sites can alter this balance by influencing signal production and attractiveness of the túngara frog (Physalaemus pustulosus). Males that call from very shallow ...
From the beginning of space era human being has launched more than 5500 rockets in space having different types of payload for various space mission carried out. These payloads, mostly satellites have many types of uses, ranging from earth observation to communication. These satellites, post usage hold ...
Similarity search is the task of retrieving data items that are similar to a given query. In this paper, we introduce the time-sensitive notion of similarity search over endless data-streams (SSDS), which takes into account data quality and temporal characteristics in addition to similarity. SSDS is ...
ABSTRACT This study was undertaken to assess the potential impact of maternal exposures to polychlorinated biphenyl (PCB), dichlorodiphenyl dichloroethylene (DDE) and methylmercury on the secondary sex ratios (the ratio of male to female live births) over a span of 23 years. The study includes prospective ...
In many of the grippers and robot hands developed so far, it is assumed that the target object is fixed firmly to the robot. However, when the object has a complicated shape, it is not easy to give a sufficient gripping force to the contact points. The hand proposed in this paper has a multi-joint 1-finger, ...
In recent years, different energy projects have been developed in the rural sector in Colombia. The projects' goal is to provide clean technologies to people in remote areas in order to increase their productive capacities and improve their quality of life. Production processes in these areas stimulate ...
Technological advances in the field of ecology allow data on ecological systems to be collected at high resolution, both temporally and spatially. Devices such as Dual-frequency Identification Sonar (DIDSON) can be deployed in aquatic environments for extended periods and easily generate several terabytes ...
We present an approach to robotic deep learning from demonstration in virtual reality, which combines a deep 3D convolutional neural network, for grasp detection from 3D point clouds, with domain randomization to generate a large training data set. The use of virtual reality (VR) enables robot learning ...
Fish poisoning is a common cause of human illness in Fiji. Poisonous substances can be initially ingested by fish that typically feast upon marine green growth, spilt oil, dirty water and silted rubbish. Humans can fall ill when eating these infected fish. This is of particular concern given that fish ...
Pseudoplatystoma Magdaleniatum is one of the most representative fish species from the Magdalena river basin in Colombia. This endemic catfish is highly valuable from the economic and environmental perspectives. Nevertheless, it is currently under threat because of the indiscriminate fishery and the ...
Dynamite fishing is a problem in the Philippines. Some fishermen are only after getting as many fish as possible without regard to the damage they are doing to the environment. The purpose of this device is to be able to put a detection system in fishing areas or protected areas to warn coast guards ...
In distant-water fishing industry, production, supply and distribution activities are realized in a dynamic environment including uncertainties of resources in fishing grounds and demands from global markets. Moreover, the capacity of the port cold storage is of great importance to the cold chain network ...
In recent years, the amount of parent fish stock of Pacific bluefin tuna is decreasing. For this reason, efforts are underway to protect tuna resources in countries around the world. In Japan, an upper limit value of the catch amount is set, and when there is a possibility that the catch amount may ...
ABSTRACT In October 2016, a rapid assessment survey of ascidian species was conducted in shellfish farms at Killary Fjord, in the west of Ireland. Two non-indigenous solitary ascidians Ascidiella aspersa and Corella eumoyta were recorded for the first time in shellfish farms at this location. Both ...
Aim: This experiment aimed to evaluate substitution of soybean meal (SBM) by black soldier fly (BSF) larvae meal in a napier grass diet as performed by an in vitro rumen fermentation system. Materials and Methods: Samples of napier grass, SBM, and BSF larvae age 1 week (BSF1) and 2 weeks (BSF2) were ...
Genetic structure of an endemic tooth-carp fish, Aphanius farsicus from four different water bodies in the Maharlu Lake basin was investigated by applying five microsatellite markers. All of the five examined microsatellite loci showed polymor-phism pattern. A total of four alleles were detected at ...
