  • Weighted sums of squares via generalized eulerian polynomials 

    Pita-Ruiz, Claudio (Fibonacci Association, 2017-12)
    We give explicit formulas for the weighted sum of squares σm-1 j=0 zj (aj + b)2, where a, b ∈ C are given, and z ∈ C, z ≠ 0, 1 is the weight. In the case a, b ∈ Z and z ∈ Q, we show that there is a one-To-one correspondence ...
  • What rules and laws does Socrates obey? 

    Levystone, David Xavier (Universidad Panamericana, 2019)
    Socrates' thought of justice and obedience to laws is motivated by a will to avoid the destructive effects of Sophistic criticisms and theories of laws. He thus requires-against theories of natural law-an almost absolute ...

    Murillo Othón, Enrique (Emerald Group Publishing Ltd., 2019-10)
    Purpose: In consideration that the purpose of talent management is to attract and nurture productive employees for the benefit of the hospitality organization, this study aims to examine why employees respond in such ...
  • Wilkie syndrome : case report 

    Gonzalez Hermosillo Cornejo, Daniel (Academia Mexicana de Cirugía, 2017)
    Background: Wilkie syndrome, also referred as superior mesenteric artery syndrome, is an unusual cause of a proximal small bowel obstruction. It is characterised by the compression of the duodenum in its third portion due ...
  • Wireless ammeter based on ZigBee for continuous monitoring of induction motors 

    Gutiérrez, Sebastián (Institute of Electrical and Electronics Engineers Inc., 2019)
    The Internet of Things (IoT) has shown the ability to exploit the potential of data, transforming objects of everyday life essentially into computers, by equipping them with sensors capable of measuring physical variables ...
  • Wireless communication for railway applications : reactive and proactive protocols 

    Del Valle Soto, Carolina; Valdivia, Leonardo; Rosas-caro, Julio (IEEE, 2019)
    Railway is a critical application; hence, all systems that composed the railway infrastructure must meet two conditions: Availability and safety. The availability ensures the continuous operation of the system; on the other ...
  • Wireless sensor network energy model and its use in the optimization of routing protocols 

    Del Valle Soto, Carolina; Velázquez, Ramiro; Rossa Sierra, Alberto (MDPI AG, 2020)
    In this study, a Wireless Sensor Network (WSN) energy model is proposed by defining the energy consumption at each node. Such a model calculates the energy at each node by estimating the energy of the main functions developed ...
  • Wireless sensor network prototype to monitor the condition of holding furnaces in the aluminum casting plant 

    Gutiérrez, Sebastián (Institute of Electrical and Electronics Engineers Inc., 2019)
    Currently in the industry, higher production levels are required every day, for this reason, it is essential that the machinery used for production is always in optimal conditions which will consequently increase the ...
  • Wireless temperature monitoring system through IoT for domestic solar water heaters 

    Gutiérrez, Sebastián; Rodrigo Cruz, Pedro Manuel; Ponce, Hiram (Institute of Electrical and Electronics Engineers Inc., 2019)
    The popularization of solar water heaters in many houses makes it necessary to create an electronic tool for monitoring water temperature as a function of time. It should be easy to use and cost effective so most of the ...
  • Untitled 

    Gutiérrez, Sebastián (Institute of Electrical and Electronics Engineers Inc., 2020)
    Modeling of Lithium-Ion Battery (LIB) is essential for studying its behavior under different operating conditions like temperature, load current and state of charge. The parameters of a LIB such as capacity, open circuit ...
