Re-envisioning Remote Sensing Applications: Perspectives from Developing Countries aims at discussing varied applications of remote sensing, with respect to upcoming technologies with diverse themes. Organized into four sections of overlapping areas of research, the book covers chapters with themes related to agriculture, soil and land degradation studies; hydrology, microclimates and climate change impacts; land use/land cover analysis applications; resource analysis and bibliometric studies, culminating with future research agenda. All the topics are supported via case studies and spatial data analysis. Features:Provides the applications of remote sensing in all fields through varied case studies and spatial data analysis Includes soil and land degradation, microclimates, and climate change impactsCovers remote sensing applications in broad areas of agriculture, hydrology, land use/land cover change and resource analysis Discusses usage of GPS-enabled smartphones and digital gadgets used for mapping and spatial analysisExplores future research agenda for applications of remote sensing in post-COVID scenarioThis book is of interest to researchers and graduate students in environmental sciences, remote sensing, GIS, agricultural scientists and managers, forestry scientists and managers, and water resources scientists and managers.

Ad-hoc networks, every node in the network communicates with other nodes directly or indirectly through intermediate nodes that relay its packets because of transmission power limit. So, all the nodes in the network are virtual routers participating in computing and maintaining the routes. Wireless LAN card can also form a temporary Ad-hoc network to share the files. Depending on the node¿s mobility, there are two types of Ad-hoc networks: Static Ad-hoc Networks and Mobile Ad-hoc Networks (MANETs). Sensor network is an example of a typical static Ad-hoc network since most sensors don¿t move at present. Typically, a sensor network is an equivalent to a static Ad-hoc network in some extent, but high density is an additional property of the sensors. A MANET is defined as a system of independent mobile nodes that can communicate over wireless links without any pre-existing infrastructure. The absence of a fixed infrastructure in MANET poses several types of challenges for it. The biggest challenge among these is routing. Routing is the process of selecting paths in a network along which to send data packets and to exchange information from one host to the other host in a network.

Fakt, ¿e w przesz¿o¿ci lekarze zajmowali si¿ wy¿¿cznie faktycznym porodem, w ¿aden sposób nie wykluczä innych doradców w czasie ci¿¿y; wr¿cz przeciwnie, z tego w¿änie powodu pacjentka by¿a odbiorc¿ wszystkich porad. Käda kobieta, która urodzi¿a dziecko, czu¿a si¿ szczególnie wybrana przez niebiosa, aby doradzä tym, którzy mieli urodzi¿ dzieci. Wraz z rozwojem opieki prenatalnej postawa ta stopniowo zmieniäa si¿, tak ¿e po¿o¿nik stä si¿ doradc¿ naczelnym, ale nadal ma liczne niezamawiane asystentki ¿wieckie. W ci¿gu tygodnia bardzo inteligentna pacjentka, ¿ona lekarza, zapytäa mnie, czy podnoszenie r¿k nad g¿ow¿ jest niebezpieczne. By¿em zaskoczony, gdy us¿yszäem tak prymitywne pytanie od tak wyrafinowanej osoby. W miar¿ mo¿liwo¿ci pacjentka powinna oddä si¿ pod opiek¿ kompetentnego, dobrze wyszkolonego specjalisty po¿o¿niczego. Przy wyborze lekarza nie nale¿y kierowä si¿ op¿at¿, któr¿ ma pobierä, gdy¿ prawie kädy lekarz jest cz¿owiekiem i dostosuje swoj¿ cen¿ do ograniczonego ¿rodka uczciwego pacjenta. Na szcz¿¿cie zakup us¿ug po¿o¿niczych nie jest jak zakup samochodu.
