Retractable Technologies (United States)

Wireless sensor networks (WSNs) are systems made up of sensor nodes that communicate wirelessly over short distances, with adaptability and functionality at their coreessence. These networks have traits. Face challenges in devising effective strategies for identifying and thwarting attacks due to limitations, in individual sensor node processing power and the essence of wireless communication. Securing WSN poses a challenge given the constrained processing abilities of sensor nodes and the inherent nature of communication while facing various security threats that have emerged alongside the widespread adoption of these networks. To protect against these dangers it's crucial to put in place the security measures Encryption's key, to keeping data safe from unauthorized users Nevertheless not all encryption methods are equally strong as some are vulnerable Elliptic Curve Cryptography (ECC) is considered the best option due to its smaller key sizes offering strong security with efficiency in space and energy As technology advances conventional encryption techniques are seen as inadequate, for ensuring data privacy and security Utilizing principles from physics to ensure data transmission, between the sender and receiver is a groundbreaking advancement in network security known as quantum cryptography. Quantum Key Distribution (QKD) combined with ECC is highlighted in this study, for authentication processes, key management and energy efficiency. A novel method called QKD ECC has been put into practice. Compared against ECC and other encryption methods to bolster the security of WSN and safeguard the confidentiality of data exchange.

Esta investigación tiene como objetivo identificar cómo debe comunicar el sector alimentación su marca empleadora en redes sociales para atraer talento de la generación Z de Lima. Específicamente, se busca explicar los motivos de los centennials para postular a una organización, descubrir cuáles son las redes sociales preferidas para obtener información sobre la compañía y determinar el contenido más atractivo. El enfoque del estudio es cualitativo, el nivel es descriptivo, el diseño es documental y fenomenológico. Las técnicas utilizadas fueron análisis de contenido, en el cual se revisaron las redes sociales de 3 empresas del sector; y entrevistas semiestructuradas a los responsables de la gestión de marca empleadora y, por otro lado, 20 estudiantes y egresados con experiencia laboral de las facultades de Negocios e Ingeniería. La información se comparó y analizó en base a la escala del atractivo del empleador (EmpAt). Los resultados muestran que las motivaciones de los entrevistados se relacionan con las dimensiones económica, social y desarrollo. Las redes sociales más alineadas a este objetivo son LinkedIn e Instagram. Finalmente, el contenido de interés en estas plataformas son la propuesta de valor al empleado (atributos), cultura, clima, testimonios de trabajadores, información realista del puesto y habilidades blandas que esperan de ellos. Asimismo, los formatos deben ser dinámicos, imágenes de calidad y videos cortos, así como texto reducido y uso de slogans o hashtags llamativos.

Abstract We have studied nine thermoplastic vulcanizate elastomers (TPVs) in four series: as made, after accelerated aging, after γ irradiation, after both irradiation and aging. The materials exhibit two glass transitions, one seen in crosslinked regions and the other in un-crosslinked amorphous regions. Three techniques of determination of glass transitions have been used and the results compared, all three based on dynamic mechanical analysis (DMA): as a peak in the loss modulus E’’; as a peak in tan δ; and as the midpoint of the rapid decrease in the storage modulus E’. We recommend the last method for both fundamental and practical reasons.
