The Times

With the progress of the times, the network has grown into the people's work and life. The limitations of the traditional wireless sensor network (WSN) have become increasingly prominent, and it is obviously unable to meet the requirements of Internet access. Therefore, the 4G mobile Android system is used as a carrier, to design an application layer gateway system for realizing wireless communication between wireless sensor networks and heterogeneous cellular networks, so as to build wireless sensor cellular network. The design and implementation of the AP module, data receiving and forwarding module, network packet loss management and retransmission of the gateway systemis the focus, and then the implemented gateway system is tested. The test results show that the design of the Android platform wireless sensor network gateway system can connect the sensor network to the cellular network, so as to realize data communication, and to ensure that the data loss rate is less than 0.1%. Through testing, it is concluded that the system can meet the actual demand

Wireless Sensor Network (WSN) extends the advantages of small price, quick employment, and shared transaction medium, although it induces a lot of security and secrecy challenges. In this paper, the Elliptic Curve Cryptography based Secure Data Communication and Enhance sensor Reliability (SDER) in WSN. In this scheme, an Elliptic Curve Cryptography (ECC) Weierstrass function is used to verify the sensor reliability, and ECC cryptography technique is useful for providing the data security in the network. The simulation result demonstrates that the SDER reduces both the packet loss rate and the network delay.

The bus is one of the mass transportation used by many people. With the rapid development of technology to find out the position of the bus, you can use a GPS tracker which has the ability to transmit real-time data. Use the barcode added to the bus ticket to find out the status of passengers getting on or off. Raspberry Pi functions to control Modem, Barcode Scanner, GPS Tracker. Raspberry Pi will process the GPS Tracker data on the bus to find out the coordinates of the bus. Barcode and GPS Tracker information will be retrieved from the webserver. Users will get bus information via a web smartphone by sending the bus police ID number. The application features contain agent information, bus destination code information, bus departure hours, bus tracking, and passenger status. Based on the test results, the tolerance value is 0.1" for latitude, the distance meter longitude value is 0.2". GPS Tracker will send more accurate data when in the city. In the Malang-Jakarta GPS Tracker test, there were not too many tree obstacles. Barcodes that have been scanned using a barcode reader will turn the seats on the display green.

We argue that developmental hormones facilitate the evolution of novel phenotypic innovations and timing of life history events by genetic accommodation. Within an individual’s life cycle, metamorphic hormones respond readily to environmental conditions and alter adult phenotypes. Across generations, the many effects of hormones can bias and at times constrain the evolution of traits during metamorphosis; yet, hormonal systems can overcome constraints through shifts in timing of, and acquisition of tissue specific responses to, endocrine regulation. Because of these actions of hormones, metamorphic hormones can shape the evolution of metamorphic organisms. We present a model called a developmental goblet, which provides a visual representation of how metamorphic organisms might evolve. In addition, because developmental hormones often respond to environmental changes, we discuss how endocrine regulation of postembryonic development may impact how organisms evolve in response to climate change. Thus, we propose that developmental hormones may provide a mechanistic link between climate change and organismal adaptation.

AbstractIf my discernment of the thought that underlies his study of Nuer religion is not entirely misconstrued, then one can assert a logical consistency between Collingwood's methodology for history and Evans-Pritchard's for ethnography. It is worthwhile, in that light, to consider the fact that "at one time Evans-Pritchard contemplated writing Collingwood's biography" (Beidelman 1974:559). One commentator, (Kuper 1980:118) typifies this methodology as "postwar idealism" and suggests that the major works he published in the later decades of his presence at Oxford demonstrate the "sterility" of his methodology and theory. Still others have hinted that his entry into the Catholic Church was later reflected in his depiction of Nuer religous life. These are remarkable assertions, when one takes the time to reflect on the many ways in which his own approach and writings have so profoundly influenced the direction of anthropological enquiry in his own country and abroad. The fact is, one can no longer write ethnography in lieu of a solid understanding of the historical circumstances which have resulted in the contemporary 'ethnographic present'. At the same time, practitioners of the discipline have addressed from almost every angle the proposition that all ethnography is indeed a good part confession-that we write what we are able to see. That is precisely the quality of the work that will guarantee the status of Nuer religion as a classic. The methods of history and anthropology can only become more similar. Anyone who holds an absence of definition or presumed repugnance toward theory as criticisms of his contributions, has truly lost the forest for the trees. It is all the more remarkable that his methodological and theoretical advances in the anthropological study of religion are to be found not in his answers, but in the questions he raised.10

This essay considers some of the insight we have gathered about language, feminism, racism and power. In many respects, it celebrates the linguistic power of the many theories about how Black women navigate intersectionality where racism and sexism intermingle, suggesting that our analyses should always recognise that a lethal combination of factors are in play. Black women, in particular, actively insist on forms of language and discourse that both represent and create their world through words, expressions and verbal routines that are created within and outside of the African American speech community to confront injustice. One example involves the verb ‘play,’ which I argue often functions as a power statement or ‘powermove’ that demands respect while presenting a threat to the status quo. This use of ‘play’ is the opposite of inconsequential games of play or joking.
