This paper applies wireless communication technology using 2.4 GHz frequency in marine field to support Vessel Monitoring System, where it sails on the island and marine field that are not getting signal coverage from Base Transceiver Station (BTS) on land. Applying of Long Range (LR) WiFi with 2.4 ...
An optimization method is proposed for the geometric parameters of an convergent nozzle ejector in the anode gas recirculation system in PEM fuel cell in this paper. The mathematical model of ejector is established by employing the hydrodynamics, thermodynamic principles and chemical constraints. An ...
OceanNet project uses a hierarchical point-to-multi-point backhaul network using long range Wi-Fi technology to provide extended offshore connectivity for fishing vessels. This work is aimed to understand the interrelationship between the design parameters and the reason for considering specific parameter ...
Green Trust, Kilowatts for Humanity, Seattle University and General Electric's We Share the Power installed a 2.4 kW solar energy kiosk in Chalokwa, Zambia. Green Trust has kept detailed records of the kiosk expenses and revenue sources, permitting a high fidelity analysis of the different aspects of ...
As the number of international tourist has been rapidly increasing recently, they have more opportunities to experience different cultures. With the upcoming Olympic game in Tokyo, Japan 2020, digital signage is expected to be utilized for an effective information presentation device for them. This ...
Food security is a prerequisite for health. Availability and accessibility of food in rural areas is mainly achieved through subsistence production in which community members use local practices to produce and preserve food. Subsistence food production ensures self-sufficiency and reduction of poverty ...
Statoliths are a pair of calcareous structures which can provide biological and ecological information for cephalopods. Understanding their shape will help us know the taxonomy of cephalopods, even to the species level. Ommastrephes bartramii, Dosidicus gigas and Illex argentinus are chosen to compare ...
Thromboxane synthase (TBXAS1) catalyzes the isomerization reaction of prostaglandin H2 producing thromboxane A2, the autocrine and paracrine factor in many cell types. A high activity and metastability by these arachidonic acid derivatives suggests the existence of supramolecular structures that are ...
Water is one of the precious factors in human life. It plays a vital role in the survival and existence of flora and fauna. But, now a days it is been exploited heavily by dumping of human waste, industrial and chemical waste in to the water bodies which is the resultant of water being contaminated ...
This paper explores the interactive art installation, Fiber Optic Ocean, portraying the consequences of technology's invasion of oceans. Three life-size shark skeletons are trapped in an ocean made of fiber optic threads. This 20-foot-by-20-foot installation combines fiber optics with sculptural elements ...
Just as in educational robotics the students solve problems in order to build their own knowledge, so too in contextualized learning the students learn by solving problems. The difference is that the former works with interdisciplinary problems that are solved by the construction and use of a robotic ...
Drawing inspiration from the psychological literature on social change [e.g., 1, 2], we classify approaches to development engineering into three categories based on the depth, sustainability, and scalability of the resultant change within a community. In this context, we define “first-order change” ...
Coral reefs are of global economic and biological significance but are subject to increasing threats. As a result, it is essential to understand the risk of coral reef ecosystem collapse and to develop assessment process for those ecosystems. The International Union for Conservation of Nature (IUCN) ...
Pectoral fin types of biological fish have an enormous diversity, and they play an essential role in locomotion of fish. The adaptation to shapes and movement mechanism of pectoral fin types helps swimming motion of the main body effectively, that results in the high flexibility and maneuverability ...
This study builds an automatic monitoring system for the fish pond culture environment. The purpose of this study is to reduce the financial losses in fish culture stock resulting from natural disasters, and facilitate better control of the fish pond environment. The physical water quality signals are ...
Underwater noise levels are increasing due to anthropogenic activities, especially in the densely populated coastal area and open ocean. Many studies have been evaluating the effect of anthropogenic noise on marine fish. However, the more information is needed to predict any negative effects. The startle ...
Petroleum hydrocarbon profiles of water and sediment samples of Algoa Bay in the Eastern Cape Province of South Africa were assessed using standard analytical procedures. Water (from surface and bottom levels) and sediment samples were collected from five locations in the bay from February to June 2016. ...
Human longevity is influenced by environment and nutrition. We considered environmental and nutritional factors relating to longevity in Chinese cities. We found higher 85+/65+ distribution ratios, indicating enhanced longevity, in the coastal and southern regions of China. These areas also featured ...
Members of the Vibrio genus are autochthonous inhabitants of aquatic environments and play vital roles in sustaining the aquatic milieu. The genus comprises about 100 species, which are mostly of marine or freshwater origin, and their classification is frequently updated due to the continuous discovery ...
The interplay between nutrition and immune system is well recognised, however the true integration of research between nutrition, animal energy status and immune function is still far from clear. In fish nutrition, especially for species maintained in aquaculture, formulated feeds are significantly ...
