Operational Efficiency (OE) and solvency play an important role in the success of any enterprises. Therefore, studying relationship between OE needs to be taken comprehensively continuously order find out long –term solutions for increasing business effectiveness. This paper examines determinants logistics joint-stock companies (JSCs) listed on Vietnam Stock market with answers above - mentione...

To develop emerging transmission techniques for potential applications of Internet Things (IoT), the system performance analysis a cognitive radio (CR)-enabled ambient backscatter (AmBC) will be studied in this paper with functionality non-orthogonal multiple access (NOMA). In proposed scheme, base station communicates two destinations via designated device. It is assumed that relay node fitted...

according to the current challenges toward low water use efficiency in agriculture, paying attention to the role of public participation in order to improve irrigation efficiency and effectiveness with useful methods and tools is essential. hence, approaches such as participatory irrigation management has been proposed and applied. after the primary investigation in this study, experiences of i...

let ‎x be an ‎‎n-‎‎‎‎‎‎square complex matrix with the ‎cartesian decomposition ‎‎x = a + i ‎b‎‎‎‎‎, ‎where ‎‎a ‎and ‎‎b ‎are ‎‎‎n ‎‎times n‎ ‎hermitian ‎matrices. ‎it ‎is ‎known ‎that ‎‎$vert x vert_p^2 ‎leq 2(vert a vert_p^2 + vert b vert_p^2)‎‎‎$, ‎where ‎‎$‎p ‎‎geq 2‎$‎ ‎and ‎‎$‎‎vert . vert_p$ ‎is ‎the ‎schatten ‎‎‎‎p-norm.‎ ‎‎ ‎‎in this paper‎, this inequality and some of its improvements ...

objectives: joint attention is one of the most important prerequisite of language and social development. there are two types of joint attention, initiating joint attention and responding to joint attention. this study examined the development of responding to joint attention in typically developing children in 8-30 month. methods: this study was cross-sectional. 61 children (40 female and 20 m...

abstract: friction stir welding, a solid state innovative joining technique, is widely being used for joining aluminium alloys for aerospace, marine automotive and many other applications of commercial importance. fsw trials were carried out using a vertical machining centre (vmc) on aa6061 alloy. the main objective of the present work was to evaluate the weld processing parameter of friction s...

Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...

In a cooperative relay network, a relay node (R) may facilitate data transmission to the destination node (D), when the latter is unable to decode the source node (S) data correctly. This paper considers such a system model and presents a crosslayer approach to jointly design adaptive modulation and coding (AMC) at the physical layer and cooperative truncated automatic repeat request (C-ARQ) pr...

We consider sensor networks where energy is a limited resource so that energy consumption must be minimized while satisfying given throughput requirements. Moreover, energy consumption must take into account both the transmission energy and the circuit processing energy for short-range communications. In this context, we analyze the energy-efficient joint routing, scheduling, and link adaptatio...
